Woodard & Curran and Tata & Howard January 2014

EXECUTIVE SUMMARY This Volume II – Sustainable Water System Plan of the Comprehensive System Facility Plan (CSFP) has been developed to enable The Maine Water Company - Biddeford and Saco Division (“Maine Water”) to make informed decisions on improvements to the Biddeford and Saco water system. It complements Volume I – Water System Assessment of the CSFP which reviews the water system’s assets and performance from source through distribution and provides recommendations for immediate and short-term enhancements. Volume I includes demand projections, an evaluation of the water source, reviews treatment facility flooding potential, and provides a detailed assessment of the treatment facility and the transmission and distribution system. The recommendations provided in Volume I are required to bring the system into compliance, improve health and safety of employees, and improve fire flow conditions within the distribution system. Volume II addresses mid and long-term concerns in the system including major rehabilitation of the treatment facility or construction of a new treatment facility. Sections 2 and 3 of Volume II detail mid-term and long-term rehabilitation recommendations for the treatment facility and distribution system. These recommendations are necessary for the long-term sustainability and efficiency of the system. Section 4 of Volume II analyzes options and costs associated with construction of a new treatment facility. The review analyzes three treatment capacity ranges, two types of treatment technologies and two potential sites for construction of a new treatment facility. Section 5 of Volume II provides a life cycle cost analysis which evaluates the cost difference between the alternatives of rehabilitating the existing treatment facility and constructing a new treatment facility. Treatment Facility Improvements The mid-term priority rehabilitation recommendations for the treatment facility total $1,865,000, and the long-term priority recommendations range from $9,700,000 to $12,900,000. These costs are separate from the immediate and short-term priority recommendations provided in Volume I that total $7,110,000. The cost and a description of each recommended upgrade is listed in the tables in Section 2. A breakdown of mid-term recommendations by location within the facility is located in Appendix A

Interconnections with Neighboring Systems As Maine Water evaluates options for upgrading the water system, there may be opportunities to sell or purchase water from neighboring systems. There are already interconnections with Kennebunk, Kennebunkport and Wells Water District (KKW) to the south that could potentially be strengthened. If Maine Water decides to pursue an interconnection with Portland Water District (PWD), transmission improvements in the area of Portland Road and Cascade Road will be necessary. Various improvements on the PWD system will also be required, depending on the volume and direction of water transferred. The costs associated with the most likely transmission recommendations for interconnection with PWD are estimated to be $3,864,000. Macro Modeling Transmission and distribution system renewal was examined at the “macro” level, in addition to the analysis performed at the pipe or “micro” level. The macro analysis considered capital renewal needs over the long term to ensure the sustainability of the water transmission and distribution system. The macro analysis indicates that for sustainable renewal, Maine Water should replace approximately 1.5 to 2 miles of pipe per year as shown in Figure ES-1. At an average of $150 per linear foot of pipe, the annual investment is approximately $1.6 million per year as shown in Figure ES-2. This annual investment increases over time peaking at approximately $1.8 million per year in 2030. While the macro model provides the over-arching annual renewal budget, the specific pipelines to be renewed are listed in the distribution system recommendations section of this report. The results of the macro analysis should be used concurrently with the mid-term and long-term prioritized distribution system recommendations which are described in this report and total $12,680,000 and $11,382,000, respectively. At an average annual investment of $1.7 million per year, the water mains recommended as mid-term and long-term priority could be replaced within approximately fifteen years.

New Treatment Facility Analysis The option to construct a new treatment facility has been analyzed as an alternative to long-term rehabilitation of the existing treatment facility. The Biddeford and Saco system has been identified as having one of the two premier sources of water supply in Southern Maine by the Maine Regional Water Council. It has capacity far beyond the Biddeford and Saco system demands as explained in Volume I. As part of a new treatment facility analysis, the potential for Biddeford and Saco to become a regional supplier of drinking water was evaluated. Three treatment capacities ranges were developed, including a 12 MGD facility extendable to 16 MGD, a 20 MGD facility extendable to 24 MGD and a 36 MGD facility extendable to 40 MGD. Costs for conventional and packaged treatment technologies were developed at each capacity.

A review of the existing site and an alternate site also owned by Maine Water was performed to identify constraints to locating a new facility. Estimated footprints for each capacity/treatment were developed. Site constraints for the existing site include: steep slopes in some areas of the site, the presence of the existing facility, challenging subsurface conditions, a large Central Maine Power easement that runs diagonally through the property, flooding potential from the Saco River and the presence of wetlands including wetlands of special significance. Site constraints for the alternate site include site access, a deer wintering area, wetlands and a 100-year floodplain. Costs for a new transmission main to the reservoir and access road work for the alternative site across the street from the existing site have been included in the cost estimates. Although easements, floodplains, topography and wetland impacts were taken into consideration in the layout options presented, the site work costs associated with these properties were not detailed in the estimates because further investigation is needed to determine specific costs.

Life Cycle Cost Analysis A life cycle cost analysis (LCCA) was performed on two alternatives: rehabilitating the existing treatment facility and constructing a new 12 MGD packaged treatment facility on the existing site. The LCCA allows comparison of the costs associated with capital investments and operations and maintenance costs of the two alternatives over the life of the facility. The following table summarizes the LCCA assumptions. The Maine Water Company - Biddeford and Saco (226317) Comprehensive System Facility Plan – Volume II

The existing facility capital investment value is a summation of the immediate, short-term, mid-term and long-term recommendations made in Volume I and Volume II. The new facility capital investment is the cost of construction of a new 12 MGD packaged treatment facility on the existing site as described in Section 4 of this report. The LCCA resulted in the following Net Present Values for the two alternatives:

Capital Investment Financing Costs Lifecycle Operations and Maintenance Total

Total LCC

The LCCA indicates that over the 50 year planning horizon, the lifecycle cost of the rehabilitated existing treatment facility would be approximately equal to the alternative of constructing a new facility. While the initial capital cost of a new facility is approximately $4 million higher than the costs to rehabilitate the existing facility, the cost to operate the existing facility is approximately $4 million higher than the costs to operate a new facility, essentially balancing the lifecycle costs. In addition to direct costs and costs that can be easily estimated, there are costs that are difficult to quantify that should be considered. These include cost associated with a higher frequency of age-related failures at the existing facility. It also includes additional construction and rehabilitation challenges at the existing facility that may lead to higher costs. Finally, the risks associated with flooding and the existing facility overall reliability are not included, but would negatively impact rehabilitating the old facility if they were monetized. These factors are not explicitly captured within the LCCA as they are difficult to quantify, but they should be considered. With an approximately $4 million difference in capital costs and a breakeven 50 year lifecycle cost, and including other considerations such as ease of capacity expansion at a new treatment facility and the precarious location of the existing treatment facility within the flood plain, Woodard & Curran recommends that Maine Water invest in a new

treatment facility. Although construction of a new treatment facility will result in a higher initial capital investment, in comparison with rehabilitating the existing facility, a new treatment facility will be more efficient, will reduce staffing and maintenance costs, will improve reliability and will ease replacements and upgrades.

1. INTRODUCTION This Volume II – Sustainable Water System Plan of the Comprehensive System Facility Plan (CSFP) has been developed to enable The Maine Water Company – Biddeford and Saco Division (“Maine Water”) to make informed decisions on upgrades to the Biddeford and Saco water system. Volume II addresses long-term options for the system including large-scale rehabilitation of the existing treatment facility and construction of a new treatment facility. Volume II complements Volume I – Water System Assessment which reviews the water system’s assets and performance from source through distribution and provides recommendations for immediate and short-term enhancements. Volume I includes demand projections, an evaluation of the water source, the flooding potential at the treatment site, and a detailed assessment of the treatment facility and transmission and distribution system. The recommendations listed in Volume I are needed to bring the facility into compliance, improve health and safety of employees, and improve fire flow conditions within the distribution system. Sections 2 and 3 of Volume II list mid-term and long-term rehabilitation recommendations for the treatment facility and distribution system. These recommendations are necessary for the long-term sustainability and efficiency of the system. Mid-term recommendations should be completed in the next 3 to 7 years to ensure continued compliance and reliability of finished water, optimize operational flexibility and extend the life of the facility. Recommendations that are categorized as long-term priority are improvements that are necessary if the decision were made to continue the use of the facility past 7-10 years. These upgrades will improve process efficiencies and ensure adequacy of equipment and facilities. Section 4 of the report analyzes options and costs associated with construction of a new treatment facility. The review analyzes three treatment capacity ranges, two types of treatment technologies, and two potential sites for construction of a new facility.

2. MID-TERM & LONG-TERM TREATMENT SYSTEM RECOMMENDATIONS This section identifies mid-term and long-term recommendations to address deficiencies at the water treatment facility. A detailed assessment of the treatment facility and a description of processes, along with immediate and short-term recommendations, are included in Volume I of this CSFP. Priority Descriptions are as follows: Mid-term: Recommendations that are categorized as a mid-term priority are improvements that, while not essential to implement immediately, must be performed in the next 3 to 7 years to ensure continued compliance and reliability of finished water production, provide capacity to meet future predicted demands, optimize operational flexibility and extend the life of the facility. Long-term: Recommendations that are categorized as long-term priority are improvements that are necessary if the decision were made to continue the use of the facility past 7-10 years. These upgrades will improve process efficiencies and ensure adequacy of equipment and facilities.

2.1 MID-TERM RECOMMENDATIONS Mid-term recommendations are listed by category in Table 2-1 and are organized by common categories (i.e. brick, roof, windows). For each issue, the table provides the area in the facility where the item is located, the item description, and recommendations. Planning level costs, which encompass design, engineering and construction, are included for each recommendation. These items are also organized by location within the facility in Appendix A. Several mid-term deficiencies listed in the table below require further evaluation and analysis to determine the extent of the required upgrades. The costs associated with these items include the estimated cost to implement subsequent upgrades or replacements; however the actual costs may vary based on the outcome of the evaluation and analysis.

Abandoned Filter Building

Metal roof deck is uniformly corroded and its load capacity is likely compromised; bar joists and joist girders are corroded but in salvageable condition; The corroded roof deck is the major potential safety hazard in this area.

Evaluate the future use of this space. If not to be used, doors should be locked to prevent entry. The metal roof deck may be in danger of failure or collapse as it continues to corrode over time. Closer inspection by a structural engineer could confirm this. If area is to be used moving forward, all observed issues should be properly addressed.

Roof steel is in fair condition, but has peeling paint.

Roof should be replaced with a new deck and membrane; roof framing should be structurally analyzed and upgraded as required to meet code. Steel framing should be repainted.

Building- Roof

General

Multiple roof areas are beyond their useful life and in need of replacement, and many areas currently leak. The Sedimentation Basin and Filter Room roofs are two sections that should be replaced in the short-term. A detailed assessment of each specific roof area is beyond the scope of this report.

A detailed assessment of each roof area should be performed and a phased approach for replacement of each section should be developed.

Filter Valve Replacement

The effluent valves in the filter gallery leak, which results in clearwell and courtyard flooding. The effluent valves need to be replaced to correct this situation. The filter gallery valves, adjacent piping and pipe supports are very old. Considering the amount of effort to replace the effluent valves and the condition of the piping and supports, it is recommended that the filter gallery piping and valves are replaced as part of one project. The project would include influent, effluent and backwash valves, all interconnected piping and associated pipe supports, as well as installation of flow meters. In addition to the cost of the large diameter piping and appurtenant items, the cost of construction considers restricted access to the filter gallery and the need for a complex temporary piping arrangement that will be required during construction.

2.2.2

Lab and Administration Spaces

A basic chemical building with no additional facilities is identified as a short-term recommendation in Volume I of this CSFP due to the numerous issues surrounding chemical handling. If a new chemical handling building is constructed, Maine Water may choose as a long-term improvement to relocate the laboratory, administrative spaces, employee kitchen and break area, and bathrooms/locker area to the second story of the new building.

2.2.3

Facility-Wide HVAC

The entire facility is heated with a combination of forced hot air furnaces and portable electric space heaters. Remnants of the original steam boiler system and discontinued hot water unit heaters remain. As part of the proposed chemical handling building recommended in Volume I of this CSFP, a centralized heating system could be installed that could heat the new space and adjacent areas. Longer term, a new centralized heating system should be extended throughout all the areas of the facility, including the filter and sedimentation basin wings. This long-term recommendation could either assume that a system large enough to serve the entire facility is installed as part of the new chemical building (one that could be expanded as part of a second project) or that a second centralize heating system is installed in another part of the facility.

2.2.4

Facility-Wide Electrical

The medium voltage entrance and distribution panels are obsolete. At some point, due to lack of available parts, code compliance issues, or equipment change out, it will become necessary to replace the system in its entirety. The existing medium voltage high-lift pump motors would require replacement if a facility-wide electrical system upgrade were to occur. In addition, given their present age, the replacement of one or both of the medium voltage high-lift pumps themselves should be anticipated during the full design life of the facility.

2.2.5

Facility-Wide Flood Proofing

”Flood-proofing” is accomplished to varying degrees within a couple of the short-term projects addressed in Volume I of the CSFP. New lagoon construction and its related courtyard improvements, the sealing of the corridor by the main entrance, and a new chemical handling building help keep portions of the facility and support facilities from being inundated. A long-term recommendation for facility flood-proofing would build upon earlier measures by potentially recontouring much of the site, removing the abandoned filter building and putting a berm around the area, and by eliminating all floor drains and other points of water back-up to the facility. Allowing the facility to be accessible, but not necessarily fully functional, during high water conditions would be the goal of this recommendation.

2.2.6

Facility-Wide Roof Replacement

Urgent roof replacements are covered under the short-term recommendations in Volume I of this CSFP and mid-term recommendations in Volume II of this CSFP. Before the design life of the facility is exceeded, virtually all roof systems (with the possible exception of the slate roof on the original building) will need replacement.

2.2.7

Intake/Headworks

The present two intakes are in close proximity to one another and at the same river depth. Benefit may be derived from locating intakes at two different depths in order to access raw water with different characteristics and treatability during different seasons and river levels. In addition, the present intakes pass through the headworks sump area and are piped directly to one or the other of the two low lift pumps. In order to provide maximum flexibility for intake selection and pump operation, a raw water wetwell (or pipe crossover and valving network) should be constructed that would allow either intake to feed either low lift pump.

2.2.8

Replace Backwash Tank

The existing backwash tank is known to be leaking. In the long-term, the present 65,000 gallon backwash tank, even if repaired, would be too small to support multiple concurrent filter backwashes that might be necessary if the facility was routinely operating near peak capacity or during extended periods of reduced raw water quality. A tank of somewhere between 120,000 gallon to 160,000 gallon capacity would be sufficient to allow multiple concurrent backwashes or a series of backwashes after short filter runs.

2.2.9

Add Third Sedimentation Basin

Although short-term recommendations addressed in Volume I of this CSFP propose ways to maximize the effectiveness of the sedimentation basins through the installation of weir troughs and lamella plates, for peak flows and primarily to provide redundancy, Maine Water should consider the installation of a third floc/sedimentation basin train in a new building extension.

2.2.10 Yard Piping Process and transmission piping within the facility property will need to be replaced as part of the long-term rehabilitation of the facility. Replacement will be complicated because of the pipe’s location within the courtyard adjacent to buildings and because the treatment facility will need to stay in operation as new piping is installed. Additionally, this work is within the 100-year flood plain and subject to flooding.

2.2.11 Lagoon System Waste Solids Removal The waste solids from the existing lagoon system will need to be removed and disposed of off-site to allow for upgrades, for the addition of the third sedimentation basin and for the yard piping project.

2.3 SUMMARY OF MID-TERM AND LONG-TERM TREATMENT RECOMMENDATIONS Mid-term and long-term treatment facility recommendations have been developed to enable Maine Water to make informed decisions about upgrades to the Biddeford and Saco water system. The total cost for all mid-term and longterm treatment system recommendations are listed in Table 3-1. These costs are separate from the immediate and short-term priority treatment system recommendations provided in Volume I of this CSFP that total $7,110,000.

3. MID-TERM & LONG-TERM DISTRIBUTION SYSTEM RECOMMENDATIONS This section provides recommendations to address distribution system deficiencies that are not immediate or short term priority. Immediate and short-term priority recommendations, along with suggested operational changes, are listed in Volume I of the CSFP. This section includes recommendations intended to eliminate insufficient storage, improve system operation, strengthen the transmission capabilities, and mitigate fire flow deficiencies. Hydraulic capacity, location in proximity to critical users and facilities, and break history were considered when prioritizing water main recommendations. Additionally, this section provides recommendations for a potential interconnection with the Portland Water District (PWD). All recommendations are prioritized based on the previously described Priority Descriptions, which are as follows: Immediate and short-term recommendations are addressed in Volume I of this CSFP. Mid-term: Recommendations that are categorized as mid-term priority are improvements that, while not essential to implement immediate, should be considered in the next five to ten years to improve the water distribution system. The mid-term recommendations are listed in Table 5-1. Long-term: Recommendations that are categorized as long-term priority are improvements that are necessary going forward to provide adequate storage, supply, and recommended fire protection to the system while planning for future growth beyond the next five to ten years. The long-term recommendations are listed in Table 5-2.

3.1 MID-TERM RECOMMENDATIONS â&#x20AC;&#x201C; WATER DISTRIBUTION SYSTEM A new 12-inch diameter ductile iron water main is recommended on West Street from Forest Street to the existing 12inch diameter water main. Currently the main in this location is 8-inch diameter. This water main will improve transmission from the Forest Street Tank and BPS to the eastern portion of the HSS. The estimated probable construction cost of approximately 7,400 linear feet of 12-inch diameter water main is $1,620,000. The existing 6-inch and 8-inch diameter water mains on Main Street and North Street should be replaced with 12inch diameter ductile iron water main from School Street to the existing 12-inch diameter water main on North Street. This improvement will improve transmission within the LSS. The estimated probable construction cost of approximately 3,700 linear feet of 12-inch diameter water main is $972,000. The existing 4-inch diameter water main on Temple Avenue between Bridge Street and West Grand Avenue in Old Orchard Beach should be replaced with 12-inch diameter ductile iron water main. By creating a grid of 12-inch diameter water main, this improvement will strengthen the transmission grid. The estimated probable construction cost of approximately 2,000 linear feet if 12-inch diameter water main is $504,000. The existing 6-inch and 8-inch diameter water mains on Pool Street should be replaced with 12-inch diameter polyethylene wrapped ductile iron water main from Pike Street to Guinea Road. This improvement will improve transmission and increase the available flow to the eastern portion of the HSS. This recommendation combined with the replacement of 8-inch diameter water main on West Street will create a grid of 12-inch diameter water main in an area of projected future growth. The estimated probable construction cost of approximately 12,000 linear feet of 12inch diameter water main is $3,213,000 Due to the proposed surplus of available storage in the Low Service System (LSS) and the condition of the Bradbury Tank, demolishing the Bradbury Tank is recommended. The hydraulic model was utilized to evaluate the impact taking the tank offline would have on pressures and available flow in the LSS. Based on the remaining storage in the service area, and the fact that the residential area surrounding the Bradbury Tank is served by the High Service System (HSS), removing the tank and the booster station has minimal hydraulic impact on the LSS. Once the tank is removed, the only storage in the LSS will be the 7.5 mg reservoir and the Pine Point Tank. The altitude valve at the Pine Point Tank should be taken out of service or replaced to eliminate the potential for over pressurizing the system if the altitude valve at the Pine Point Tank were online and the control valves at the Reservoir were closed. The estimated construction cost for demolishing the existing Bradbury Tank is approximately $150,000.

A new 16-inch diameter corrosion-protected ductile iron water main is recommended to replace the existing 8-inch diameter cast iron water main on Pool Street and Newtown Road from Guinea Road to the proposed tank location near the UNE athletic facilities on Pool Street. The estimated construction cost of approximately 11,300 linear feet of 16-inch diameter water main is $3,314,000. A new 16-inch diameter ductile iron water main is recommend on Lina Avenue and Industrial Park Road in Saco from Shadagee Road to the existing 16-inch main at Lehner Road. A new 16-inch tap to the existing 24-inch main should be completed to provide the full capacity of the new 16-inch main, while eliminating the existing 6-inch restriction. This improvement will improve transmission in the LSS area. The existing water main is 12-inch cast iron. The condition of this water main should be evaluated. If the water main is in fair to good condition, a parallel 12-inch diameter water main could be considered. The estimated construction cost of approximately 2,100 feet of 16-inch diameter water main is $604,000. To strengthen distribution capabilities and provide recommended residential fire flows in the Camp Ellis area of Saco, cleaning and lining the existing 8-inch diameter, 1909, cast iron water main on Ferry Road and Lower Beach Road from Bayview Road to the end is recommended. The estimated construction cost of approximately 7,000 linear feet of cleaned and lined 8-inch diameter water main is $1,007,000. Prior to implementing this improvement, it is recommended that a pipe assessment is performed to confirm the condition of the water main. The assessment should calculate the pipe wall thickness and to determine the extent of internal and external corrosion. Furthermore, this recommendation was made based on the assumption that the water main has not experienced significant breaks. If institutional knowledge identifies this water main as having experienced several breaks, unrelated to joint breaks or construction site error, then it is recommended that this water main be replaced with new 8-inch diameter corrosion-protected ductile iron pipe. The estimated construction cost of approximately 7,000 linear feet of new 8-inch diameter water main is $1,540,000. To improve residential fire flows in the Camp Ellis area of Saco, new 8-inch diameter corrosion-protected ductile iron water main is recommended to replace the existing 6-inch diameter cast iron water mains on Camp Ellis Avenue from Ferry Road to Fore Street, Pine Tree Avenue from Lower Beach Road to Main Avenue, Main Avenue from Pine Tree Avenue to North Avenue, and North Avenue from Main Avenue to Beach Avenue. The estimated construction cost of approximately 2,450 linear feet of 8-inch diameter water main is $469,000. A new 8-inch diameter ductile iron water main is recommended on Portland Avenue from Walnut Street to the existing 8-inch diameter water main on Portland Avenue. Replacing the existing 6-inch diameter water main will reduce the bottleneck in the LSS. The estimated construction cost of approximately 1,900 linear feet of 8-inch diameter water main is $357,000. A new 8-inch diameter ductile iron water main is recommended on Jordan Street and Bonython Avenue from North Street to the existing 8-inch diameter water main. Replacing the existing 2-inch and 6-inch diameter water mains with new 8-inch diameter water main will improve residential fire flows in the area. The estimated construction cost of approximately 1,350 linear feet of 8-inch diameter water main is $254,000. To improve residential fire flows in the Glenwood Avenue neighborhood, a new 8-inch diameter ductile iron water main is recommended to replace the existing 6-inch diameter cast iron water mains on Lawn Avenue, Birch Street, and Glenwood Avenue from Beach Street to Laurel Avenue. The estimated construction of approximately 1,150 linear feet of 8-inch diameter water main is $216,000.

3.2 LONG TERM RECOMMENDATIONS â&#x20AC;&#x201C; WATER DISTRIBUTION SYSTEM STUDY To provide capacity to meet the estimated ISO recommended fire flow at the University of New England campus on Hills Beach Road, a new 12-inch diameter corrosion-protected ductile iron water main is recommended to replace the existing 8-inch diameter cast iron water main on Hills Beach Road from Pool Street to Old Pool Road. The estimated construction cost of approximately 2,300 linear feet of 12-inch diameter water main is $591,000.

To improve residential fire flows on Moody Street in Saco, a new 8-inch diameter ductile iron water main is recommended to replace the existing 6-inch diameter cast iron water main on Moody Street from Main Street to the end of the road. The estimated construction cost of approximately 2,450 linear feet of 8-inch diameter water main is $460,000. To strengthen transmission capabilities and improve the estimated ISO recommended fire flows in downtown Old Orchard Beach, a new 12-inch diameter corrosion-protected ductile iron water main is recommended to replace the existing 10-inch diameter cast iron water main on Grand Avenue between the existing 12-inch diameter water main at Ladd Avenue and Old Orchard Street. The estimated construction cost of approximately 4,500 linear feet of 12-inch diameter water main is $1,155,000. A new 12-inch diameter ductile iron water main is recommended on Hillview Avenue and Buxton Road from Jeffery Avenue to Wendy Way in Saco to replace the existing 8-inch diameter water main. This will improved transmission in the LSS. The estimated construction cost of approximately 2,600 linear feet of 12-inch diameter water main is $683,000. The LSS has a projected 1.75 mg of surplus storage. The 7.5 mg reservoir is old and the existing lining system could be leaking and the floating cover has historically caused problems. It will likely continue to be an issue in the future. It is recommended that Maine Water Company construct a new water storage tank at the reservoir location and abandon the existing reservoir. Then new tank should be designed to provide 2.5 mg of usable storage. The estimated construction cost for abandoning the existing reservoir and constructing a new water storage tank is approximately $3,000,000. It is important to note that the timing for when this improvement is necessary may change based on the results of the recommended tank inspection and leakage test. The recommendations from the HSS Evaluation and Tank Siting Study should be used to design and construct a new water storage tank in the HSS. The estimated construction cost of the tank depends on the construction material, site conditions, site location, and tank size. The estimated construction costs range from $1,800,000 to $2,100,000. These estimates do not include costs associated with land acquisition, easements, permits, legal fees, excessive site work, or distribution system modifications to connect the tank to the existing distribution system. To provide the estimated ISO recommended residential fire flows in the Pine Point area of Scarborough, new 8-inch diameter corrosion-protected ductile iron water main is recommended to replace the existing 6-inch diameter cast iron water main on Jones Creek Drive between Pine Point Road and Avenue 5 and on Avenue 5 between Jones Creek Road and King Street. The estimated construction cost of approximately 2,400 linear feet of 8-inch diameter water main is $459,000. To strengthen transmission capabilities, improve the fire flows in downtown Old Orchard Beach, and replace a section of water main with a history of significant breaks, a new 12-inch diameter corrosion-protected ductile iron water main is recommended to replace the existing 10-inch diameter cast iron water main on Grand Avenue between Pine Point Road and the existing 16-inch diameter water main at Longwave Place. The estimated construction cost of approximately 3,350 linear feet of 12-inch diameter water main is $860,000. A 12-inch diameter corrosion-protected ductile iron water main is recommended on Hills Beach Road from Old Pool Road to Ocean Edge Lane to provide estimated ISO recommended residential fire flows. The estimated construction cost of approximately 5,900 linear feet of 12-inch diameter water main is $1,317,000. To strengthen distribution capabilities and improve fire flow on Fern Park Avenue, it is recommended to connect the dead end water mains on Laurens Drive and Balsam Lane with new 8-inch diameter ductile iron water main. The existing 4-inch diameter water main on Balsam Lane should be replaced with new 8-inch diameter water main. The estimated construction cost of approximately 600 linear feet of 8-inch diameter water main is $113,000. To provide the capacity for the estimated ISO recommended fire flow to the Salvation Army facilities off of Church Street, a new 12-inch diameter water main is recommended to replace the existing 6-inch diameter cast iron water

main on Eleventh Street from Evergreen Avenue to Maplewood Drive. The estimated construction cost of approximately 300 linear feet of 12-inch diameter water main is $94,000. A new 12-inch diameter water main is recommended to replace the existing 6-inch diameter cast iron water main on Bluff Avenue to provide the estimated ISO recommended residential fire flows. The estimated construction cost of approximately 200 linear feet of 12-inch diameter water main is $63,000. A new 8-inch corrosion-protected ductile iron water main is recommended to replace the existing 6-inch diameter cast iron water main on Ocean Avenue between Grand Avenue and Seaside Avenue to provide the estimated ISO recommended fire flow. The estimated construction cost of approximately 300 linear feet of 8-inch diameter water main is $102,000. The sections of 6-inch diameter cast iron water main along Smithwheel Road should be replaced with new 8-inch diameter ductile iron water main to improve distribution capabilities and provide estimated ISO recommended residential fire flows. One section is located between Ervin Avenue and the existing 8-inch diameter water main located to the northwest of Ervin Avenue, and a second section is located between Valle Lane and the existing 8-inch diameter water main located to the southwest of Valle Lane. The estimated construction cost of approximately 2,050 linear feet of 8-inch diameter water main is $385,000.

3.3 INTERCONNECTION WITH PORTLAND WATER DISTRICT There may be opportunities to sell or purchase water from neighboring systems. To provide redundancy to the system, a future interconnection with the Portland Water District could be considered. If Maine Water decides to pursue an interconnection in the future, the following transmission improvements will be necessary to purchase large amounts of water. A new 20-inch or larger diameter ductile iron water main is recommended on Portland Road from the existing 12-inch diameter water main on Portland Road to Cascade Road. Replacing the existing 8-inch diameter water main will improve transmission in the LSS. The estimated construction cost of approximately 3,400 linear feet of 20-inch diameter water main is $1,173,000. A new 20-inch or larger diameter ductile iron water main is recommended on Portland Road from Cascade Road to the Scarborough town line, along with a new 20-inch or larger diameter water main on Cascade Road from Portland Road to Milliken Mills Road. The condition of the 16-inch water main should be evaluated. The estimated construction cost of approximately 7,800 linear feet of 20-inch diameter water main is $2,691,000.

3.4 MACRO MODELING The Biddeford & Saco water system is similar to many other aging water systems that began installing pipe in the late nineteenth century. The robust nature of cast iron pipe, which constitutes a bulk of the system’s piping, has delayed the need to invest in widespread distribution system rehabilitation and replacement (renewal). Even though cast iron pipes have extended useful lives that can exceed 125 years, their lives are not infinite. Maine Water can expect that a considerable portion of older water mains will reach the end of their useful lives in the next few decades and will require renewal. Investment in the renewal of these aging assets will be required to maintain current level of service. Delaying this investment will likely result in lower service levels, more frequent leaks and breaks, and increased expenditures for emergency repairs. This will ultimately require significantly more money to address. Macro modeling provides a way to evaluate the long term pipe renewal picture. It can help predict the needed investments to sustainably managing the distribution system. Although the macro analysis can tell you how much pipe to renew, it does not specify which individual pipe segments to renew. The micro analysis provides pipe asset renewal recommendations by evaluating risks associated with individual pipe segments and prioritizing renewal based on pipeline specific data. The prioritized list for the Biddeford & Saco system is provided in the Distribution System Recommendations (Section X) portion of this report. Combining the macro and micro analyses provides Maine Water with a defensible and sustainable long-term distribution renewal plan. Macro analysis tools, such as KANEW and the Buried No Longer Pipe Replacement Modeling Tool (which was recently developed by the American Water Works Association) help water systems understand long-term pipe renewal needs. The Buried No Longer Tool is derived from a comprehensive, national-level analysis of the cost and timing of the investments necessary for sustainable distribution system renewal. Keys to development of the model included: 

Tracking the timing of water system development through grow and recession over the last 150 years;



Cataloging the materials from which pipes were made and where and when pipes of each material were likely to have been installed;



Measuring the service lives of the various pipe types and sizes in actual operating environments;



Developing replacement costs for each type and size of pipe; and



Establishing a probability distribution to estimate service life for each pipe group; these values can be adjusted for local conditions and differences.

The Buried No Longer model has twelve sub-models that encompass three water system size categories in four regions of the US (very small, medium small and large; and northeast, south, Midwest and west). Data used by the model’s developers included: 

Regional pipe installation profiles by system size and pipe diameter from USEPA, water industry and US Census Bureau data



AWWA Water/Stats database



USEPA Community Water Supply Survey



2002 Public Works Infrastructure Survey



Survey of professionals in the field

Figure 3-1: Historical Production and Use of Water Pipe by Material1 This data was used along with a “typical” useful service live which assumes that pipe is replaced at the end of the pipe’s useful life. The result is a Nessie Curve, which is a graph of the annual replacement needs for a specific water system, based on when pipes were installed and how long they are expected to last in that water system. The model takes into account pipe failure probability distributions based on a compilation of various utilities’ current operating experiences, extensive research and professional experience. The model assumes “typical” service lives of each material type for each regions/sizes as shown in Figure 3-2. Note that the service lives for pipes within a particular water system may vary from the “typical” as the rate of deterioration is not determined solely by the age of the pipe, but rather is the cumulative effect of pipe installation practices, soil conditions, the quality of the material and other factors. For example, the Biddeford & Saco system may have pipes with services lives greater than 100 years whereas other utilities may conversely be observing significantly shorter services lives, because of local conditions. Although the Buried No Longer Tool has not been developed to allow the user to input specific services lives, Woodard & Curran is working with the Tool’s developer to expand the model to allow water system specific calibration based on known conditions including leak and break rates.

Figure 3-2: Derived Current Service Lives for Installed Mains2 3.4.1 Model Inputs The macro model requires utility-specific data including distribution system commencement date, population served, expected growth rate, pipe costs and summary of pipe materials and sizes in the distribution system. The model provides system growth profile options based on the commencement date of the distribution system. The model allows the selection of a growth profile based on region/size or the most representative growth profile based on utility specific cumulative percent of pipe installed per decade. The utility specific cumulative percent of pipe installed per decade is only applicable if the utility has accurate pipe installation information. Otherwise, the sub-model is selected based on the utility’s region and size. Biddeford & Saco’s distribution system GIS data was analyzed to develop the inputs for the Buried No Longer Tool. The Buried No Longer Tool allows input of the following material categories: cast iron, concrete lined cast iron, ductile iron, asbestos cement, PVC, steel and concrete & PCCP. The Biddeford & Saco data was adjusted for consistency with model terminology and to fill in missing data gaps. As with any data adjustment such as assuming material types based on installation year, a degree of imprecision is introduced into the model; however as approximately 15 percent of the pipes had unknown material types, the model would be significantly less accurate if the pipes with unknown material types were omitted from the model. The following assumptions were made based on review of available data and based on the distribution system analysis in Section 8 of Volume I of this report.

3.4.2 Model Results The analysis uses the Nessie Model to combine demographically based pipe inventories with average service lives to yield an estimate of how much pipe of each size and material must be replaced in each of the coming years to the year 2050. The model is scaled based on specific water system inputs and the average cost to replace these pipes is applied to determine the total investment for each year. The tool outputs a series of graphs (Nessie curves) that display the amount of investment required in each future year to replace each of the different pipe materials and size categories. The macro analysis for the Biddeford & Saco system indicates that for sustainable renewal, Maine Water should replace approximately 1.5 to 2 miles per year as shown in Figure 3-2. At an average investment of $150 per linear foot of pipe, the annual investment is approximately $1.6 million per year as shown in Figure 3-4 and Figure 3-5. This annual investment increases over time peaking at approximately $1.8 million per year in 2030. While the macro model provides the over-arching annual renewal budget, the specific pipelines to be renewed are listed in the distribution system recommendations section of this report. The results of the macro analysis should be used concurrently with the mid-term and long-term prioritized distribution system recommendations which were described previously in this report and totaled $12,680,000 and $11,382,000, respectively. At an average annual investment of $1.7 million per year, the water mains recommended as mid-term and long-term priority could be replaced within approximately fifteen years. The following figures are the graphical outputs of the model and include the estimated miles of replacement per year, estimated replacement investment by pipe material and by pipe size category and the estimated investment per capita of population served.

Figure 3-3: Estimated Replacement in Miles per Year Figure 3-4 depicts cumulative investment by pipe material type whereas Figure 3-5 depicts cumulative investment by pipe size category (pipe diameter). While cast iron is generally the oldest pipe in a system, it has a longer service life than many other materials so the oldest pipes in the system will not necessarily be the first renewed. As shown in Figure 3-4, the investment should shift over time.

4. NEW TREATMENT FACILITY OPTIONS An analysis of options for construction of a new treatment facility was performed. The analysis is a planning level review which takes into account three production capacity range options, siting options and two treatment technologies.

4.1 PRODUCTION CAPACITY OPTIONS The Biddeford and Saco water system is located adjacent to multiple southern Maine water systems including Kittery Water District (Kittery), Kennebunk, Kennebunkport and Wells Water District (KKW), York Water District (YWD) and the Portland Water District (PWD). The Biddeford and Saco system has been identified as having one of the two premier sources of water supply in southern Maine by the Maine Regional Water Council. As part of a new treatment facility analysis, it is prudent to evaluate the potential for Biddeford and Saco to become a regional supplier of drinking water. The three production capacity options considered, which are detailed subsequently, are as follows: 1. Capacity for Biddeford and Saco’s projected 2050 demands 2. Capacity for Biddeford and Saco’s projected 2050 demands, plus additional capacity to supply Kittery and KKW’s anticipated surface water demands 3. Capacity for Biddeford and Saco’s projected 2050 demands, plus additional capacity to supply all of Kittery, KKW and YWD’s demands and roughly half of Portland’s anticipated demands

4.1.1

Capacity for Biddeford and Saco

A demand projection was given for the Biddeford and Saco system in Volume I of this report. The demand projection did not include any future demands from adjacent regional water systems. The results were a 2050 average day demand range of 4.5-7.1 MGD, a maximum day demand range of 8.1-12.8 MGD and a peak week demand range of 7.7-12.0 MGD. The maximum day demand is capable of being buffered by the system’s storage of approximately 3 MG and, therefore, the capacity of a new treatment facility is based on the peak week future demand. Using this projection, a 12 MGD facility that is expandable to 16 MGD is appropriate. Another potential capacity consideration is an interconnection with the Portland Water District. A letter from the Portland Water District to Tata & Howard dated July 18, 2013, states that through hydraulic modeling, it appears Portland Water District could provide 3.7 MGD to the Biddeford and Saco system after major upgrades to the Portland Water District’s distribution system including the addition of an interconnect between the two systems. If Maine Water chooses to work with the Portland Water District on an interconnection, the design capacity of the Biddeford and Saco treatment facility could be reduced to 8-10 MG with the Portland interconnect supplying the additional peak week flows. In this case, the facility should allow for future extension to 12 MGD. This production point is comparable to that envisioned in Volume I for the proposed upgrades to the existing treatment facility. As such, the costs for this new facility option and PWD interconnection should be compared to the costs developed for the existing facility rehabilitation option.

4.1.2

Additional Capacity for Kittery and KKW’s Surface Water Demands

In considering Biddeford and Saco as a regional supplier, the new facility would likely need to supply water to Kittery as well as replace KKW’s aging surface water treatment facility. KKW obtains a portion of their present supply from groundwater wells, and it was assumed that they would continue to rely on those wells for a future portion of their needs. Kittery’s current demands average approximately 2.2 MGD in the summer, spring and fall and 3.4 MGD in the winter; however demands in the winter can spike to 3.8 MGD. The increase in winter demands is due to consumption at the Portsmouth Naval Shipyard. Demands have been fairly steady over the last few years, but they have the potential to decrease with changes in workload at the shipyard. The Maine Water Company - Biddeford and Saco (226317) Comprehensive System Facility Plan – Volume II

4-1

Woodard & Curran and Tata & Howard January 2014

KKW’s current demands average approximately 6 MGD in peak summer months and 1.25 to 2 MGD in the winter. KKW’s production has increased slowly over the last few years with residential construction. District staff indicate that approximately 60 percent of the summer production, or approximately 4 MGD, comes from their surface water source with the remaining 40 percent coming from their groundwater wells. The wells have minor iron and manganese concerns as well as supply limitations. The surface water source, Branch Brook, is very limited in capacity. The historical demand analysis for the Biddeford and Saco system revealed a declining trend in per capita water use. Even with modest residential growth, the declines in per capita water use result in a leveling off or, in some cases depending on growth, declining water demands into the future. It is anticipated that this trend is generally applicable to other southern Maine water systems and therefore, it is estimated that Kittery and KKW’s future demands will be similar to current peak demands; although this should be vetted before any future facility is designed. The estimated capacity of a treatment facility capable of supplying Biddeford and Saco, Kittery and KKW’s 4 MGD surface water demand totals approximately 20 MGD. The layout for such a treatment facility should be designed for 20 MGD and allow for extension to 24 MGD.

4.1.3

Additional Capacity for KKW Wells, YWD and to Supplement PWD

This option includes capacity for Biddeford and Saco, all demands for Kittery, KKW, YWD and back-up supply for PWD. This option is likely to be considered in only long term planning scenarios as it would require major upgrades to the distribution networks, particularly when considering large volume transfers north to the Portland system. In addition to the previous option’s 20 MGD for the Biddeford and Saco, Kittery and KKW surface water demands, the facility would be required to produce an additional 2 MGD in place of KKW’s well supply, 2 MGD for YWD and half of PWD’s estimated 25 MGD demand. This totals approximately 36 MGD. The layout for the treatment facility include should be designed for 36 MGD and allow extension to 40 MGD.

4.1.4

Summary of Capacity Options

4.2 SITE REVIEW This section provides a review of the existing site constraints and discusses how these constraints can impact the development of a new treatment facility. As part of this analysis, both conventional filtration and packaged filtration treatment technologies, and assumed a facility size of 16 MGD, expandable to 24 MGD and/or 40 MGD were considered. The analysis considered treatment facility development at both the existing treatment facility parcel and the nearby reservoir parcel. Maine Water owns two parcels of land along South Street: the treatment facility parcel at 466 South Street, adjacent to the Saco River and identified as Tax Map 2-40; and the reservoir parcel, located at 439 South Street, identified as Tax Map 2-19. The locations of these two parcels are shown on Figure 4-1.

Figure 4-1: Parcel Options The review considered several potential development constraints as part of this evaluation, including topography, floodplains, wetlands, soils, habitats, easements, zoning restrictions and access. Readily available mapping documentation from City of Biddeford GIS databases as well as the existing conditions survey and wetland delineation recently performed at the treatment facility site was utilized.

4.2.1

Topography

A survey of the existing treatment facility parcel was provided by Royal River Survey; and is attached as Appendix B of this report. The site generally slopes from southwest to northeast. The site contains several areas of steep slopes, and in some cases slopes exceed 2H:1V and have embankment heights of over 20 feet. Areas with steep slopes include portions of the site adjacent to South Street, areas adjacent to the access road, and a large portion of the north corner of the parcel. Construction in these areas of steep slopes will result in substantial earthwork prior to new building construction. Field survey information was not available at the reservoir property; therefore topography information from GIS maps as well as visual observations of the site were used to conduct this review. The following figure shows the topography of the site, with 10â&#x20AC;&#x2122; contour intervals.

Woodard & Curran and Tata & Howard January 2014

Figure 4-2: Reservoir Parcel Topography Topographic mapping indicates that the site generally slopes from South Street towards the reservoir at roughly a 6 percent slope. The areas adjacent to the reservoir are relatively flat. A review of these figures indicates that the reservoir property appears to be the preferable site from a topographic perspective.

4.2.2

Floodplain

Review of FEMA Firm maps indicate that both parcels have areas designated as the 100-year floodplain. The treatment facility parcel is located within the floodplain of the Saco River, and has a history of flood impacts. FEMA has established a flood elevation of 62 in this area. This flood elevation is shown on the planning schematics attached as Appendix D, and show on the following GIS map for reference.

500 year floodplain

Figure 4-3: Treatment Facility Parcel Floodplain Approximately one-fourth of the existing treatment facility site is within the 100-year floodplain, including the treatment facility and lagoon system. All proposed site improvements within the 100-year floodplain will require additional fill to bring structures above the flood elevation, and/or construction of flood berms or other mitigation measures, potentially adding significant costs to the development. The reservoir parcel also contains some areas within the 100-year floodplain, although no elevation has been set by FEMA for this area. The floodplain delineation is shown on the following figure as well as on planning schematics in Appendix D. Given the size of the parcel, Woodard & Curran anticipates that significant impacts to this floodplain can be minimized, and that the reservoir site is preferable from a flooding perspective.

Wetlands

Wetland areas appear to be present on both the treatment facility and reservoir sites. A wetland delineation of the treatment facility site was performed by FB Environmental Associates in September 2013. The report, which is included in Appendix C, includes a description of soils, as well as an identification and classification of wetlands. The locations of the wetlands are also shown as green hatches on the planning schematics in Appendix D. As shown in the following figure, a large area in the south corner of the site has been delineated as wetlands. The wetlands are described as having been significantly disturbed as a result of historical land uses including agriculture, development and deposition of fill material. Several species of invasive plants were documented throughout the site.

Woodard & Curran and Tata & Howard January 2014

Figure 4-5: Treatment Facility Wetland Delineation A portion of the wetlands are located within the 100-year FEMA floodplain and therefore are classified as Wetlands of Special Significance. Impacts to these wetlands will require significant levels of compensation, as described in following sections of this report. The wetland delineation also identified a potential vernal pool in the northern portion of the site, although FB Environmental notes that the vernal pool is unlikely to be classified as significant. Additional review of this area in the spring (including counting of egg masses) will be necessary to fully classify this area. Woodard & Curran reviewed National Wetland Inventory Maps to determine if any known wetland areas are mapped for the reservoir site. These mapped wetland areas are shown as dark blue on the following GIS map, with municipal buffer areas shown in light purple.

Woodard & Curran and Tata & Howard January 2014

Figure 4-6: Reservoir Parcel Mapped Wetlands No field wetland delineation was conducted on the reservoir site, and consequently the actual location of wetlands can vary significantly from the mapped locations. However, these maps are a good indication that wetland areas are likely to be present at the reservoir parcel. Due to the size of the parcel, a full wetland delineation of the 126 acres would be cost prohibitive. Instead, it is recommend that a wetland scientist walk the site and provide siting recommendations, if Maine Water chooses to further pursue a new treatment facility at this site.

4.2.4

Soils

No geotechnical investigation was conducted as part of this planning exercise, so information regarding soils is relatively unknown. The wetland delineation indicates that soils between the treatment facility and South Street are poorly draining and have slow permeability. These soft soils will likely require large investments in foundations for a new treatment facility. If Maine Water chooses to further pursue development of a new treatment facility, it is highly recommend that exploratory geotechnical analysis of the potential sites be conducted prior to advancement of a site design.

Habitats

Information from the Maine Natural Areas Program, Department of Agriculture, Conservation & Forestry and the Maine Department of Inland Fisheries and Wildlife (IF&W) was requested to determine if any known rare or threatened habitats are located within the area. Documentation from these review agencies is included as part of Appendix C. Woodard & Curran has received confirmation that no known rare or threatened botanical features are located within the treatment facility site; however Red Maple Swap, which is an exemplary natural community, has been identified within the reservoir parcel. Although it appears that the Red Maple Swap is located southwest of the anticipated development area, the agency review does not provide a definitive delineation, and an on-site assessment by a biologist would be required to confirm the extents of the feature.

Figure 4-7: Red Maple Swamp The Maine Department of Inland Fisheries and Wildlife (IFW) reviewed the two parcels in regards to wildlife habitat and confirmed that no known rare or threatened species are mapped for this area. Please note, IFW confirmed that the reservoir parcel is listed as Deer Wintering Habitat, and will be classified as a significant wildlife habitat, which may result in additional permitting through the Maine DEP Natural Resources Protection Act. As suggested by IF&W, forestry regulations and guidelines for management of Deer Wintering Areas should be followed to minimize impacts to this habitat.

The existing treatment facility site contains a 100-foot wide easement for Central Maine Powerâ&#x20AC;&#x2122;s (CMP) high voltage overhead electrical system. This easement cuts diagonally through the western half of the site. The location of the easement is shown on the survey attached as Appendix B as well as the planning schematics in Appendix D. The configuration and location of the easement represents a significant site constraint for the treatment facility site, because it reduces the amount of contiguous land available for development. Relocation of the easement would likely represent significant costs and require additional time for negotiation with the utility company and development of new legal documents. Since no survey of the reservoir site has been conducted to date, there is limited information available regarding the easements on the property.

4.2.7

Zoning Restrictions

The zoning maps and local land use regulations were reviewed as they pertain to these two sites. A copy of the zoning map is shown on Figure 4-8.

Woodard & Curran and Tata & Howard January 2014

Figure 4-9: Zoning Map The treatment facility parcel is located within the Suburban Residential 1 (SR1) Zone and portions of the site within 250 feet of the Saco River are designated as being in the Limited Residential Shoreland Overlay Zone. Setbacks for structures in this zone are listed as 40-feet along South Street frontage and 10-feet along the side and rear property lines. The reservoir parcel is located within the Rural Farm (RF) zone, and has setback of 40-feet along South Street frontage and 25-feet along the side and rear property lines. The local regulatory permitting requirements will largely be driven by the “use classification” assigned to the new treatment facility. Water treatment facilities are not currently listed in the City’s Table of Land Uses, and therefore the extent of local permitting is difficult to determine at this stage. If Maine Water chooses to further pursue the development of a new treatment facility, meeting with City Planning officials prior to finalization of site development is recommended. In general, it is anticipated that permitting of development within the treatment facility parcel may be more challenging because the shoreland zone will require additional regulatory review.

4.2.8

Site Access

The treatment facility parcel has over 1,000 feet of frontage along South Street which can be utilized to establish access to the new treatment facility. As discussed above, the topography along South Street and the access path includes some steep side slopes which will need to be considered during establishment of access paths. The reservoir site is rather limited in site access. A wet area of significant size is located along the South Street frontage. An easement was provided across abutting properties for the existing access road to the reservoir. Maine Water should review their easement to determine if it is restricted for access to the reservoir exclusively, or if it could The Maine Water Company - Biddeford and Saco (226317) Comprehensive System Facility Plan – Volume II

Woodard & Curran and Tata & Howard January 2014

be used to access the property for treatment facility operations. In addition to the cost of easements, the road would likely require upgrades in order to accommodate access to the treatment facility. The reservoir is approximately 3,200 feet from South Street, so these road upgrades would be a significant cost.

Both sites have constraints that will need to be thoughtfully considered during the design of a new treatment facility. Although these site constraints do not eliminate the potential for a new treatment facility, they have the potential to add time and cost to the project. They also drive the selection of treatment technology options towards those that require a smaller footprint on the treatment facility parcel.

4.2.10 Planning Schematics To better understand how the constraints identified above impact the development of a treatment facility, a series of planning figures, which are attached as Appendix D, are provided. Conventional filtration and packaged filtration treatment facilities with an assumed initial capacity of 16 MGD, 24 MGD and 40 MGD were evaluated. These represent the maximum anticipated size of the three size range options considered for a new treatment facility. The following table summarizes the potential footprints for each treatment capacity and treatment technology.

The planning schematics are based on facility capacity at full expansion (16 MGD, 24 MGD and 40 MGD), and take into account layout considerations for expansion from base capacities. These footprints are for planning purposes only and would need to be refined in the preliminary and design phases. Three site locations for the treatment facility were considered: 

Northwest Quadrant of the treatment facility parcel, between the CMP Easement and South Street



Southwest Quadrant of the treatment facility parcel, in front of existing treatment facility



Adjacent to the reservoir

The following sections describe the suitability of these three sites for treatment facility development.

4.2.10.1Northwest Quadrant of the Treatment Facility Parcel For purposes of this analysis, the Northwest Quadrant is defined by a triangular piece of land east of the setback from South Street, south of the side setback, and west of the CMP Easement. This area of the site is approximately 2.5 acres. Although clear of wetlands, the topography of the area includes steep embankments and ravines. This quadrant is likely not of sufficient size to support a 40 MGD conventional filtration facility. An example of a 16 MGD Facility, expandable to 24 MGD, is shown on Figure 1A in Appendix D. Note that the 24 MGD conventional facility is likely to infringe upon the CMP easement and the setbacks. Furthermore, the northwest quadrant does not have sufficient area for the lagoons, which would need to be located to the southwest resulting in wetland impacts and associated compensation costs. The packaged filtration facility, shown in Figure 1B of Appendix D, can accommodate up to a 40 MDG facility in this northwest quadrant. The footprint is significantly smaller than that of the conventional treatment facility because a packaged facility does not require sedimentation basins. Lagoons will still need to be located to the southwest resulting in wetland impacts and associated compensation costs. Wetlands impacts of this nature will be difficult to permit, because Maine Water would need to document that no other alternative is available. Wetland impacts also have significant compensation costs. As a point of reference, the in-lieu compensation costs for impacts to the 1.6 acres of wetlands in front of the treatment facility would cost approximately $300,000, according to the current Maine DEP’s In-Lieu Compensation Rates, per the rates published on their fact sheet http://www.maine.gov/dep/land/nrpa/ILF_and_NRCP/ILF/fs-in-lieu.pdf. Please note this rate could further escalate if the wetlands are determined to be within significant wildlife habitat.

4.2.10.2Southwest Quadrant of the Treatment Facility Parcel The Southwest Quadrant is described as a piece of land east of the setback from South Street, north of the side setback, and west of the existing treatment facility. This area is approximately 5 acres in size; 1.6 acres of which are wetlands. Roughly half of the area is within the 100 year floodplain.

Woodard & Curran and Tata & Howard January 2014

An example of a 16 MGD conventional filtration facility, expandable to 24 MGD and 40 MGD, is shown on Figure 2 in Appendix D. As you will note, the conventional facility and lagoons will impact significant areas of wetlands, including wetlands of special significance. As noted above, the compensation and associated permitting costs for these wetland impacts will be significant.

4.2.10.3Adjacent to Reservoir In light of the significant constraints to construction of a new treatment facility on the existing site, it is recommended that Maine Water consider the reservoir parcel as a potential development site. An example of a conventional treatment facility is shown on Figure 3 of Appendix D. A principal advantage of locating a new treatment facility in the vicinity of the reservoir is that there appears to be a large suitable building site. A conventional filtration facility, fitted with a gravity sedimentation step, tends to occupy a larger footprint than some other package-type treatment methods. A conventional filtration facility has the advantage of more robust performance and recovery in periods of high loading during high raw water turbidity events, and generally lower energy requirements compared to the upflow adsorption clarifiers and their captive media which require backwashing and scouring. A second significant advantage of locating a new facility near the reservoir is that it would be possible to convert the treatment system to a single-pumped system. New raw water pumps, installed in a new or redesigned facility on the present treatment site, could move water to the high elevation treatment facility. From there the reservoir and the distribution system (other than the high service zone) could be served by gravity. One downside to operating in this fashion is that initial calculations suggest that the present transmission line between the existing treatment facility and the reservoir is suitable for only upwards of 14 MGD flow. This line could continue to be used for a new treatment facility constructed at the first breakpoint of 12 MGD to serve the existing Biddeford-Saco service territory. This process consideration also applies for construction of a treatment facility on the existing site. Any future facility capacity expansion to serve areas to the south of Biddeford, or deliver large volumes of water to PWD would require a new transmission line be included as an element of the expansion project. Other advantages to the upland site include moving away from the residential neighborhood surrounding the existing facility, reducing concerns with flooding, and co-locating a staffed treatment facility adjacent to the storage reservoir (or some future replacement reservoir). This provides an additional measure of security for the reservoir, which is remote and susceptible to vandalism. As described above, additional research into site accessibility, wetland delineation, and site soils is recommended prior to finalizing site selection; however overall, the reservoir site appears to be the preferred location.

4.3 TREATMENT TECHNOLOGIES The existing treatment facility utilizes conventional treatment which has historically performed well for the Biddeford and Saco system. When considering design of a new treatment facility, it is prudent to evaluate multiple technologies to ensure the most cost effective and reliable technology is utilized. This section describes the technologies that were evaluated as well as provides parameters for the selected treatment technologies. Existing source water conditions, chemical application rates and process design criteria are described in Volume I of this CSFP.

4.3.1

Conventional Filtration

4.3.1.1 Traditional Layout Conventional filtration, utilizing alum or PAC-based flocculation, gravity settling, and dual media filters, is the existing treatment method and the one most likely to successfully treat the full range of Saco River water conditions. Filters could be within cast-in-place concrete basins or in painted steel or stainless steel tanks. Steel tank based filters The Maine Water Company - Biddeford and Saco (226317) Comprehensive System Facility Plan â&#x20AC;&#x201C; Volume II

4-15

Woodard & Curran and Tata & Howard January 2014

would be easier to situate on an upland site since they could be located in a building with a shallow foundation and with greater access to the interconnected piping gallery. Steel tanks also lend themselves to simpler building arrangements that could be more readily expanded to the second and third production volumes, should this become necessary. The selection of steel tanks would reduce initial capital costs but would likely increase maintenance costs. Whether steel or concrete filters are selected, it is envisioned that plastic sectional underdrains, such as those manufactured by Roberts or Leopold would be installed. Such filters, with their sintered or slotted caps, eliminate the need for media support gravel while improving uniform filtration. Filters would be fitted with an air scour system with air discharge headers mounted above the underdrain for ease of maintenance and to avoid the risk of air-binding the underdrains. Individual filter monitoring, filter-to-waste, and automated backwashing based on differential pressure or breakthrough would be included in a new design. A conventional flocculation/sedimentation step would be based on the design parameters previously noted. Sedimentation basins would be concrete and would be paired with two filters each. Sedimentation basins could be located beneath the filter level, or could be located outside from the filtration building. Other than concrete tank tops and access structures, no additional building coverage would be necessary above the basins. Disinfection contact chambers, a separate chloramination basin, and finished water clearwells could be located beneath the filtration building floor. Given the operating history of the Biddeford-Saco system, an ozone preoxidation step does not appear necessary and would only add complexity. Given the systemâ&#x20AC;&#x2122;s Long Term II Enhanced Surface Water Treatment Rule (LT2) Bin classification, continued primary disinfection using chlorine should be sufficient for the foreseeable future. Conversion to chloramines to provide a distribution system residual should continue to be practiced. Potential layouts on the existing site are shown for the 16 MGD and 24 MGD options. Both would be crowded in the available area and by the Central Maine Power right-of-way. The fully built-out 40 MGD option would not fit to the west of the CMP easement but could be located within the south corner of the site within the floodplain and wetland zones. Sufficient land exists near the reservoir site to accommodate even the largest build-out of a conventional filtration system.

4.3.1.2 Packaged Layout One modification to the classic conventional filtration system is the use of packaged treatment units, such as those produced by Trident or Suez-Degremont. These packaged filters, in steel tanks or concrete basins, paired with captive plastic media in high-rate upflow adsorption clarifiers can significantly reduce the footprint and construction costs for a conventional filtration facility. Steel tank units typically range in capacities up to 2 MGD each, while concrete basin mounted units can be sized for up to 20 MGD each. For the full build out at 40 MGD, steel tank units would be impractical for a single facility. At the lower production breakpoints, the use of steel tanks could be justified, particularly if there was a significant interval between the initial construction and the first expansion. High rate clarifiers are not as resilient during high turbidity spikes, such as can occur on the Saco River, as traditional settling basins. In addition, they are far more sensitive to coagulant dosing. From an operations standpoint, it would be preferable to consider traditional settling basins if the upland reservoir site was considered for development. Highrate, upflow clarifiers with packaged filters may be the only filtration option feasible on the existing facility site, given the space constraints.

4.3.2

Direct Filtration & Pressure Filters

Direct and pressure filtration systems without pre-treatment such as sedimentation or clarification are generally not be suitable for source waters that could see turbidities exceeding 5-10 NTU. Pressure filters are typically for lower flow applications and for groundwater sources, principally for iron and manganese removal. Experience has shown that the turbidity in Saco River water settles readily, even during periods of high turbidity. From an operations standpoint, the easiest and best location for removing these readily settleable solids would be during a separate The Maine Water Company - Biddeford and Saco (226317) Comprehensive System Facility Plan â&#x20AC;&#x201C; Volume II

4-16

Woodard & Curran and Tata & Howard January 2014

sedimentation treatment step. Removal of solids through a clarification step, such as that of a packaged facility is also possible, but less robust than through conventional sedimentation. Clarification tends to struggle water that has turbidity over 50 NTU. The tradeoff is the higher construction cost of conventional sedimentation basins. Direct and pressure filtration alone without pre-treatment would not be suitable for a source such as the Saco River and for the capacities and reliability required of the Biddeford-Saco treatment system. Since the floc at the existing treatment facility has been observed to settle under gravity conditions quite readily, there is no operational driver to employ more complex, energy intensive measures such as dissolved air floatation or ballasted floc systems. The only reason to consider these technologies would be to reduce the treatment facility footprint, but this would come with proportionately greater operational costs that are not justified.

4.3.3

Membrane Treatment

While some membrane treatment facilities have been sized as large as 100 MGD, the technology is most appropriate for facility sizes less than 5 MGD and for facilities with extremely high raw water quality. Low chemical consumption and backwash volumes are membranes biggest advantages. They are, however, a high energy process and are not well suited to source waters susceptible to turbidity spikes.

4.4 COSTS Planning level costs associated with a new treatment facility were developed using formulas presented in the Cost Estimating Manual for Water Treatment Facilities in combination with data from similarly-sized treatment facilities constructed in New England within the last 5 years.3 Although the manual was developed based on national costs, as described below, regional construction costs were also reviewed for comparison. It was impractical to base costs solely on the similar treatment facilities build in New England, since relatively few facilities in the size ranges considered have been constructed in the last 5 years. As the Cost Estimating Manual for Water Treatment Facilities manual was developed in 2007, an ENR cost factor of 1.17 was applied to the estimated costs to bring costs to 2013 dollars. The estimated costs were developed using the formulas for individual processes and components of a treatment facility. These costs were then summed as a process subtotal and additional percentages were applied for sitework, yard piping, landscaping, site electrical and controls, engineering, legal, administration and twenty percent contingency. Also included as appropriate were estimated costs for replacement of the transmission main to the reservoir and access road work for the alternative site across the street from the existing site. The individual values associated with each of these line items are included in Appendix E. The cost estimates were developed based on the following criteria.

As the selected technologies are similar to the current treatment, the estimate assumed continued use of the chemicals currently used unless otherwise recommended in Volume I of this report including sodium hypochlorite, aluminum sulfate, sodium aluminate, polymer, lime, fluoride, phosphate and aqua ammonia. For each initial capacity, it was assumed that the filter building footprint required for the extended capacity would be built in the first phase of the project (for example, the initial 12 MGD facility footprint would be designed to accommodate the process equipment for the extended 16 MGD capacity), and the additional filters required to extend the treatment capacity would be installed during a second phase. Additional sedimentation basins and lagoons were also assumed to be installed as part of the second phases. For the existing site, the additional lagoons required for the 36 MGD and 40 MGD conventional option are located at a higher elevation than the treatment facility and will require pumping. These costs have been included in the estimate. On the existing site, the 12 MGD facility will not require replacement of the transmission main from the existing site to the reservoir; however, costs associated with all other capacities including extension to 16 MGD include the cost for the replacement of this transmission main. The planning level cost estimates below assume site work adds 15 percent to the process construction total. Due to the numerous existing site constraints on both sites as previously discussed, it is anticipated that the site work costs will likely be higher than this, especially considering potential impacts to protected resources. Although easements, floodplains, topography and wetland impacts were taken into consideration in the layout options presented, the site work costs associated with these were not specifically included in the estimates below because the magnitude of the costs will be specific to the chosen site. A more detailed site work cost should be investigated and determine after a decision has been made to move forward with construction of a new treatment facility and a site has been selected. The estimated costs do not include costs associated with demolition of the existing treatment facility. The layouts have been designed such that the building and lagoon footprints are outside of the existing treatment facility footprint. The estimated costs do not include the costs associated with additional survey, wetland delineation or soils investigation necessary for site selection. The following table includes planning level cost estimates for construction of a new treatment facility on the existing site for each selected technology at each selected treatment capacity including the additional cost to extend the facilityâ&#x20AC;&#x2122;s capacity. A more detailed estimate is located in Appendix E.

A new facility on the alternate site would have similar costs as a facility on the existing site except that the alternate site allows for a single-pump system, which should eliminate the need for pumping into the distribution system, and the alternate site requires upgrades to the existing 3,200 LF access drive. With the reduction in costs due to elimination of pumping and addition of costs due to the access road upgrades, the total capital costs for each site are very similar. A life-cycle cost analysis including operations and maintenance costs was not performed. This type of analysis may show that eliminating secondary pumping significantly reduces long-term operations costs. The estimate assumes that the existing access road will continue to be used and upgraded to a paved roadway for improved access to allow for higher levels of traffic such as chemical deliveries. If it is determined that the access drive does not have an easement that allows use for a new treatment facility, then the costs of constructing a new access road within the property boundaries would be higher than estimated. As the road requires upgrading for any size facility, the transmission main replacement was assumed to be included in the cost of construction at the 12 MGD capacity. Other site elements that have been considered in the facility layout, but that have not been captured in the estimates due to lack of site information, include costs for potential ledge removal and blasting and any costs associated with construction within the deer wintering areas. The following table includes planning level cost estimates for construction of a new treatment facility on the alternate site for each selected technology at each selected treatment capacity including the additional cost to extend the facilityâ&#x20AC;&#x2122;s capacity.

In addition to providing formulas for the individual process costs as previously described, the capital cost for conventional treatment per million gallons per day treatment capacity are provided. The cost estimated for the Biddeford and Saco treatment facility, which were developed by estimating the costs of individual process items and components, are also shown on the graph. This graph illustrates that the costs estimated for the 12/16 MGD facility are within 18 percent, and estimated costs for the 20/24 MGD and 36/40 MGD facilities are within 5 percent of the general estimate based on treatment facility capacity.

The construction costs for the 25 MGD alternative water treatment facility constructed in 2008 in Pawtucket, RI, totaled approximately $44,000,000. This facility included upflow clarifiers, GAC filters, UV disinfection and a 5 million gallon clearwell. Note that the capital costs of these technologies are more expensive than conventional treatment and the 5 million gallon clearwell is atypical for a facility of this size.



The construction costs for a 4 MGD water treatment facility constructed in 2009 in Portsmouth, NH, totaled approximately $18,000,000. The facility included dissolved air flotation (DAF) with conventional filters.

Construction costs for each option for Biddeford and Saco are included in Appendix E and include the sum of the Subtotal Process Cost, the Sitework, Yard Piping, Landscaping and Site Electrical and Controls line items. The Lawrence, MA, project construction costs are within 0.1 percent of the construction costs estimated for the Biddeford and Saco 16 MGD conventional facility, and the Pawtucket, RI project construction costs are within 10 percent of the construction costs estimated for the 24 MGD conventional facility for Biddeford and Saco. These comparisons confirm the cost ranges estimated for the new Biddeford and Saco treatment facility.

5. LIFE CYCLE COST ANALYSIS A life cycle cost analysis (LCCA) was performed on the alternatives of rehabilitating the existing water treatment facility and construction of a new 12 MGD packaged treatment facility on the existing site. The LCCA allows comparison of the costs associated with capital investments and operations and maintenance of the two alternatives over a defined time period. In the case of this analysis, a 50 year period was selected corresponding to the expected useful life of a new treatment facility.

5.1 LIFE CYCLE COST ANALYSIS METHOD AND ASSUMPTIONS One of the best ways to compare mutually exclusive alternatives is to summarize their estimated lifecycle costs in present day dollars. The Net Present Value method, which allows for comparison of uneven cash flows among alternatives by discounting and then summarizing annual and future costs to present day value is the desired tool for this analysis. Costs include capital investment costs, annual operations and maintenance costs and financing costs. Engineering economic analysis focuses on the future consequences of current decisions. Because these consequences are in the future, they must be estimated and cannot be known with certainty. The following assumptions were incorporated into this analysis. One of the fundamental principles in engineering economics analysis is that in choosing between completing alternative, the emphasis is on the difference between the alternatives; therefore costs that would be equal for both alternatives have not been included in this analysis. The analysis does not include revenue as it is anticipated that as the treatment facilities are the same capacity, the revenue from each alternative would be equal. Additionally, intermittent capital replacement costs have not been included as it is anticipated that after initial rehabilitation of the existing facility was complete, intermittent capital replacement costs would be approximately equal across both alternatives. The planning horizon for this analysis was selected to be 50 years and it is assumed that the useful life of each alternative equals the planning horizon. Fifty years was selected as this is the anticipated life cycle of a new treatment facility before large scale upgrades, such as structural upgrades would be required. Additionally review of the existing facility showed approximately a 50 year cycle between major upgrades, with the facility being constructed in 1880, and major upgrades in the 1930s and 2010s. Although the existing facility has not had a major upgrade in 70 years, the upgrades that are being conducted were delayed and likely should have been performed prior to the turn of the century. The discount rate of 10% percent was selected based on discussions with Maine Water. The present loan interest rate was based on the current Drinking Water State Revolving Loan Fund (SRF) lending rate of 2 percent. It is estimated that in the future, the loan rate will increase to 4%. A 30 year SRF loan is anticipated. The following table summarizes the LCCA assumptions.

Salvage costs were not included in the LCCA due to the assumption that the investment is intended to be long-term, with no expectation of salvaging of assets. The salvage values would be similar between alternatives. Future intermittent capital costs associated with wear and tear of equipment and facilities were not included in this analysis. These costs are difficult to estimate for a new facility and even more challenging for an aging facility without meticulous historical records, which were not available for the Biddeford & Saco treatment facility. These costs will certainly be higher for the existing facility as compared with a new facility. For example, it is anticipated that roof repairs, outside of the ones specifically mentioned in this report, will cost more than similar repairs to a new facility. Repairs to older facilities typically require upgrading to current building codes, working with non-standard or obsolete equipment, and unusual measurements (non-square openings, old standards, etc.). It is anticipated that the roof upgrades for the existing facility will cost approximately $15 more per square foot more than similar replacements on a newer facility. This results in approximately $450,000 more costs over the lifecycle of the existing facility (roof lives are approximately 20 years which results in two replacements within the analysis lifecycle leading to an estimated additional $1 million in cost for maintenance to the existing facility.) Due to the complexity of determining replacement costs and the specific timing of these costs, they were not included in the LCCA. This results in a slightly lower LCCA value for the existing facility. These additional costs should be subjectively considered in the evaluation.

5.2 CAPITAL INVESTMENTS The existing treatment facility’s capital investments are a summation of the immediate, short-term, mid-term and long-term treatment facility recommendations detailed in Volume I and Volume II, which total $21,875,000. The new facility’s capital investments is the estimated cost of construction of a new 12 MGD packaged treatment facility on the existing site as detailed in Section 4 of this report, which totals $26,000,000. Construction of a new facility on the reservoir site and/or a larger facility was not evaluated using the LCCA methodology even though they may be a more desirable alternative from other perspectives. This type of comparison was not considered equivalent.

5.3 FINANCING COSTS Renewal of the existing treatment facility was assumed to be financed through SRF loans initiated in 2014 to finance the immediate and short-term capital recommendations, 2016 to finance the mid-term recommendations, and 2020 for the long-term recommendations. Financing costs for the new facility assumed an SRF loan for the entire cost of the capital investment initiated in 2015.

5.4 OPERATIONS AND MAINTENANCE COSTS It is anticipated that the annual costs to operate and maintain the existing facility will be greater than the costs to operate and maintain a new facility. The anticipated operations costs are broken down into six categories including: 

Staffing Costs



Electrical Costs



Heating Costs



Chemical Costs



Remaining Operations & Maintenance Costs

Operations and maintenance costs were estimated based on Public Utilities Commission (PUC) reports from 2008 to 2012 and input from Maine Water. Though PUC reports provide valuable data, it appears that some of the cost categories overlap resulting in double-counting of some costs such as labor. Adjustments were made based on available data to account for overlapping categories. For LCCA purposes, annual costs are assumed at the end of each year. The following are the operations and maintenance assumptions that were included in the analysis. The Maine Water Company - Biddeford and Saco (226317) Comprehensive System Facility Plan – Volume II

Woodard & Curran and Tata & Howard January 2014

5.4.1 Staffing Costs Based on the PUC reports and discussions with staff, the number of staff required to operate and maintain the existing water treatment facility includes one dedicated lab employee and seven general water treatment operators. It also assumes that there are two fully staffed shifts per weekday and one partial weekend shift. A new treatment facility would have a significantly higher degree of SCADA automation than the existing facility. This automation would reduce the need for staff. It is assumed that new facility could be operated by a total of five operators working overlapping shifts. A dedicated lab employee would not be required due to automated sampling. The facility would operate without staffing during certain periods through careful monitoring and a highly automated SCADA system. Based on PUC reports and for the purposes of this analysis, it is estimated that employee salaries average $60,000 a year, including all overhead costs and benefits. A review of PUC reports and discussions with Maine Water indicate an average of a 3 percent annual raise in employee salaries.

5.4.2 Electrical Costs A 2005 Power Assessment of the existing treatment facility performed by Woodard & Curran estimated that the facility purchases an average of approximately 2 gigawatt-hours of electricity annually at a cost of approximately $180,000. A new facility could reduce electrical costs by approximately 20 percent through more efficient piping configurations, better use of shoulder and off-peak pumping, more efficient electrical equipment, and elimination of space heaters in the chemical areas.

5.4.3 Heating Costs The new treatment facility is anticipated to have a smaller footprint than the existing facility, and the new facility would be designed to meet current energy codes which require a substantially higher thermal resistance value than the existing building. Much of the existing facility is not heated or is marginally heated, so it is difficult to use historical heating costs as a guide. For the purposes of this life cycle cost analysis, it is assumed that the heating costs for each alternative are equal.

5.4.4 Chemical Costs The existing facility purchases approximately $130,000 in chemicals annually. It is anticipated that the higher degree of SCADA automation at a new facility including such changes as pacing chemicals to flow would lead to approximately 15 percent savings in chemical costs.

5.4.5 Remaining Operations & Maintenance Costs The existing facility's remaining operations and maintenance costs averaged $100,000 annually, which includes maintenance, materials, supplies, contractual services, transportation and other miscellaneous expenses related to treatment facility operations but excludes the previously described labor, electrical, heating and chemical costs. It is anticipated that due to efficiencies in construction and operations of a new treatment facility, the new treatment facility operations and maintenance would be approximately 50 percent more efficient than the existing facility.

5.4.6Summary of O&M Annual Costs All annual costs were inflated by the assumed interest rate (except salaries which were inflated by 3 percent as previously discussed). The following table summarizes the O&M assumptions made for this LCCA.

Biddeford-Saco Wetland Delineation- October 2013

1.0 INTRODUCTION FB Environmental (FBE) was contracted by Woodard & Curran to conduct a wetland delineation for approximately 18.5 acres of land located at 466A South Street in Biddeford, Maine (Figure 1). The project area is located at the Maine Water- Biddeford Saco water treatment facility, which supplies drinking water to the cities of Biddeford, Saco, Old Orchard Beach and Scarborough. The existing facility was constructed in 1881 and renovated in 1936. Maine Water is proposing to update and expand the facility, which in addition to the renovation or complete reconstruction of the existing building, will involve the construction of several lagoons used to temporarily store water used to back-flush water filters. Section 2 of this report provides an overall description of the survey area. Section 3 describes wetland survey methodology, and survey results are presented in Section 4. Appendix A contains photographs from the delineation. Appendix B includes letters of correspondence from Maine Natural Areas Program (MNAP) and the Maine Department of Inland Fisheries and Wildlife (MDIFW). Appendix C includes copies of original wetland delineation data forms completed during the field survey. 2.0 SURVEY AREA 2.1 General Site Description The survey area is located at the Maine Water- Biddeford and Saco water treatment facility, between South Street in Biddeford, Maine and the Saco River (Figure 1). The site is divided roughly in half by the facility’s access road. The area to the east of the road is bound by the access road to the west, by a steep bank leading to South Street to the south, by a steep bank bordering an adjacent landowner’s property to the east, and to the north by the Saco River. Hydrologic inputs to this area consist of precipitation, runoff from adjacent slopes, and connections to the groundwater table. The treatment facility is located in the north-east corner of the survey area approximately 25 feet from the bank of the Saco River. An approximately ¼ acre treatment lagoon is situated just east of the facility. To the south of the facility is approximately six-acres of reverting field/pasture that is currently a complex mosaic of wetland and upland areas. Conversations with Maine Water employees indicate that the field was mowed in the past, has served as both hayfield and pasture for horses, and that tile drains were installed at some point, presumably to improve the area for agricultural purposes. A large, approximately ¼ acre pile of silt, that has been excavated from the aforementioned lagoon, was documented at the northeast end of the field. A leaky fire hydrant, southwest of the treatment facility Area 1. View north towards treatment facility from has resulted in a small wet area (~ 10' x 10'). wetland 1A.

The western portion of the survey area is bound to the east by the access road, to the south by South Street, to the west by a residential area and to the north by the Saco River. Hydrologic inputs to this area consist of precipitation and connections to the groundwater table. This area is predominantly forested, and is bisected by a transmission line corridor that runs southeast to northwest. A power station is located along the west side of the treatment facility access road. An abandoned house and detached garage are located at the southern end of the survey area along South Street. An additional old (collapsed) garage was documented to the northeast. Old car parts, a large bottle dump, and other debris are present throughout this portion of the study area. In addition, several invasive plant species were noted within the area including Oriental bittersweet (Celastrus orbiculatus), honeysuckle (Lonicera tartarica) and Japanese barberry (Berberis thunbergii) and multiflora rose (Rosa multiflora), indicative of the disturbed nature of this portion of the survey area. Overall, the project area includes a number of natural resource features including several unmapped wetlands and the Saco River and its floodplain. The wetlands within the survey area include emergent wetlands (PEM), scrub-shrub (PSS), and a forested wetland (PFO). 2.1 Soils Description Soils information for the survey area was obtained from the USDA-Natural Resources Conservation Service Soil Data Mart (USDA-NRCS, 2013) and the Soil Survey of York County, Maine (USDA Soil Conservation Service, 1982). Soils within the survey area include Scantic silt loam (Sc) and Buxton silt loam (BuB & BuC) (Figure 2). Scantic silt loam (Sc) is considered a hydric soil in Maine. It is a nearly level, poorly drained, deep soil found at low elevations. It receives runoff from adjacent, higher areas. The surface layer is typically nine inches thick and consists of dark greyish brown silt loam. The subsurface layer typically five inches thick consisting of mottled, olive gray silty clay loam. The subsoil is mottled, dark grayish brown and olive gray, firm silty clay 22 inches thick. The substratum is firm, mottled, olive gray silty clay to a depth of 60 inches or more. The soil has a moderate or moderately slow permeability in the surface and subsurface layers and slow or very slow permeability in the subsoil. Buxton silt loam, 3 to 8 percent slopes (BuB) is a gently sloping, somewhat poorly drained, deep soil. Areas of this soil are oval or finger-shaped and typically range in size from 3 to 20 acres. The surface layer is typically dark brown silt loam seven inches thick. The upper part of the 30-inch thick subsoil is yellowish brown and mottled, light olive brown silt loam and mottled, light brownish grey silty clay loam. The lower part is firm, mottled, olive gray and grayish brown silty clay. The substratum is firm, mottled, olive gray silty clay to a depth of 60 inches or more. The soil has moderate or moderately slow permeability in the surface layer and upper part of the subsoil and slow or very slow permeability in the lower part of the subsoil and in the substratum. Buxton silt loam, 8 to 15 percent slopes (BuC) is a sloping, somewhat poorly drained, deep soil. Areas of this soil are oval or finger-shaped and typically range in size from 4 to 30 acres. The surface layer is typically dark brown silt loam seven inches thick. The subsoil is 30 inches thick, the upper part of which is yellowish brown FB Environmental Associates, Inc.

and mottled, light olive brown silt loam and mottled, light brownish gray silty clay loam. The lower part is firm, mottled, olive gray and grayish brown silty clay. The substratum is firm, mottled, olive silty clay to a depth sometimes exceeding 60 inches. The soil has a moderate or moderately slow permeability in the surface layer and upper part of the subsoil and slow or very slow permeability in the lower part of the subsoil and in the substratum. 3.0 REVIEW OF BACKGROUND INFORMATION 3.1 National Wetland Inventory Maps The National Wetland Inventory Maps (NWI) are produced by the U.S. Fish and Wildlife Service (USFWS) and are produced using aerial photography and infrared color photography. The USFWS provides information on the characteristics, extent, and status of the nation's wetlands and deepwater habitats and other wildlife habitats. Wetland Inventory Maps of this project area were acquired from the Maine Office of GIS. There is one mapped NWI wetland within the survey area (Figure 2). NWI classifies the small wastewater lagoon on the north-east corner of the survey area as an excavated palustrine wetland (PUBHx). However, conversations with facility employees indicate that the lagoon is lined. Therefore the lagoon would not meet the regulatory definition of a wetland because it will not meet the soil and possibly vegetation requirements. Lack of ground-truthing to create NWI maps sometimes result in misclassification such as this. 3.2 Maine Natural Areas Program Correspondence A letter was sent to the Maine Natural Areas Program (MNAP) by Woodard & Curran on September 16, 2013 requesting a search of their Biological and Conservation Data System files for rare or unique botanical features and Registered Critical Areas known to occur at or near the survey area. Rare and unique botanical features include the habitat of rare, threatened, or endangered (RTE) plant species and unique or exemplary natural communities. A reply letter was sent on September 26, 2012 from Don Cameron of MNAP stating that there are no known rare botanical features documented within the project area (Appendix B). 3.3 Maine Department of Inland Fisheries and Wildlife Correspondence A request was sent to the Maine Department of Inland Fisheries and Wildlife (MDIFW) on September 16, 2013 for review of any known or potential significant wildlife resources (Appendix B). The purpose of this review is to aid in documenting potential rare species or habitats along the project area so that avoidance, protection and mitigation steps can be taken. As of the writing of this report, a reply letter has not yet been received.

4.0 SURVEY METHODS 4.1 Wetland Delineation Survey methods followed standard practice for a routine wetland delineation using the Regional Supplement to the Corps of Engineers Wetland Delineation Manual (USACE, 2012). This methodology involves identifying wetlands based on three main criteria: Hydrophytic Vegetation, Hydric Soils, and Hydrology. For a given area to be considered a wetland, all three of these criteria must be met. Hydrophytic vegetation is defined as the community of macrophytes that occurs in areas where inundation or soil saturation is either permanent or of sufficient frequency and duration to influence plant occurrence (USACE, 2012). Vegetation data were based on the percent aerial coverage for each plant species visually estimated within a 30’ plot for the tree stratum, a 15’ plot for the sapling/shrub stratum, and a 5’ plot for the herb stratum. Sample points were selected within each wetland and within the adjacent upland. A hydric soil is a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (USDA Soil Conservation Service, 1994). The concept of hydric soils includes soils developed under sufficiently wet conditions to support the growth and regeneration of hydrophytic vegetation (Environmental Laboratory, 1987). Soils within the survey area were examined using soil augers for reconnaissance purposes, and where practicable, soil pits were hand dug ~ 18 inches deep to document soil profiles. Soil test pits were located as close to the wetland-upland transition as practicable to better constrain soil properties in the transition region. Determination of whether hydric soils were present was carried out according to the methods in the Field Indicators of Hydric Soils in the United States (USDA-NRCS, 2010). The term "wetland hydrology" encompasses all hydrologic characteristics of areas that are periodically inundated or have soils saturated to the surface at some time during the growing season. Areas with evident characteristics of wetland hydrology are those where the presence of water has an overriding influence on characteristics of vegetation and soils due to anaerobic and reducing conditions, respectively. Hydrology is often the least exact of the parameters, and indicators of wetland hydrology are sometimes difficult to find in the field (Environmental Laboratory, 1987). Indicators of hydrology, if present, were noted at all wetland and upland test pits. Glo-pink “Wetland Delineation” flagging was sequentially numbered and hung at intervals along wetland boundaries within the survey area. Blue flags were sequentially numbered and labeled as TOB (top of bank) along the edge of the river. TOB flags at the edge of the survey area were labeled as “start open” or “end open”, indicating that the resource continues beyond the survey area. Red flagging was used in indicate wetland and upland soil determination pits (DP). Orange and black striped flagging was used to demarcate small upland islands within a wetland.

4.2 Wetlands of Special Significance In Maine, Wetlands of Special Significance (WoSS) are regulated by the Maine Department of Environmental Protection (DEP) under chapter 310 of the Maine Natural Resources Protection Act. All coastal wetlands and great ponds (inland bodies of water >10 acres in size) are classified as WoSS. In addition, a freshwater wetland may be considered one of special significance if it: (1) contains a natural community that is critically imperiled or imperiled as defined by the Maine Natural Areas Program; (2) contains significant wildlife habitat; (3) is located within 250 feet of a coastal wetland; (4) is located within 250 feet of a great pond; (5) contains at least 20,000 square feet of aquatic vegetation, emergent marsh vegetation, or open water; (6) is inundated with floodwater during a 100-year flood event based on flood insurance maps (Figure 3); (7) is or contains peatlands; and (8) is located within 25 feet of a river, stream or brook. The survey area was assessed for WoSS.

4.3 Rivers, Streams and Brooks Rivers, streams and brooks were determined according to the definition of “River Stream or Brook” provided in Maine’s Revised Statutes, Title 38, § 480-B (9). "River, stream or brook" means a channel between defined banks. A channel is created by the action of surface water and has two or more of the following characteristics: (A) It is depicted as a solid or broken blue line on the most recent edition of the U.S. Geological Survey 7.5minute series topographic map or, if that is not available, a 15-minute series topographic map; (B) It contains or is known to contain flowing water continuously for a period of at least 6 months of the year in most years; (C) The channel bed is primarily composed of mineral material such as sand and gravel, parent material or bedrock that has been deposited or scoured by water; (D) The channel contains aquatic animals such as fish, aquatic insects or mollusks in the water or, if no surface water is present, within the stream bed; (E) The channel contains aquatic vegetation and is essentially devoid of upland vegetation. "River, stream or brook" does not mean a ditch or other drainage way constructed, or constructed and maintained, solely for the purpose of draining storm water or a grassy swale. Rivers, streams and brooks were documented if present within the survey area. 4.4 Potential Vernal Pools Vernal pools are a protected natural resource feature both at the state and federal level. At the state level, vernal pools meeting specific criteria are considered significant wildlife habitat under Chapter 335 and are a protected resource under the Natural Resources Protection Act (NRPA). Before making a significance determination, a feature, often identified as a potential vernal pool (PVP) must first meet either the federal and or the state definition of a vernal pool. Whether a vernal pool is significant or not is based on the number and type of amphibian egg masses, the presence of fairy shrimp, or use by threatened or endangered species. Both the pool and its critical terrestrial habitat (within 250’ of the pool) are protected under these rules. A vernal pool is considered significant if it contains any number of fairy shrimp (at any life stage) or the presence of at least 10, 20, or 40 Blue-spotted Salamander (Ambystoma laterale), Spotted Salamander (Ambystoma maculatum), or Wood Frog (Lithobates sylvaticus) egg masses, respectively. At the federal level, vernal pools are less strictly defined and are protected on a case-by-case basis, largely reliant upon both the definition of ‘vernal pool’ included in the Department of the Army, General Permit (PG), State of Maine, and the functions and values of the vernal pool. Potential vernal pools were documented if present within the study area.

5.0 SURVEY RESULTS 5.1 Description of Delineated Wetlands (Copies of all field survey forms are located in Appendix C) Wetlands were delineated over six days on September 18-20 and 23-25, 2013. FBE Wetland Scientist Kevin Ryan and Wetland Scientist/Project Manager Jennifer Jespersen conducted the survey. FBE Project Scientist Logan Cline assisted with the delineation on September 18th. Four wetland areas were identified and delineated in Area 1: 1A, 1B, 1C, and 1D. Two wetland areas, 2A and 2B, and two single line drains, 1 and 2, were delineated in Area 2 (Figure 4). Delineated wetlands are described below. Photos of the wetlands and other areas notable features within the survey area are included in Appendix A. Wetland 1A Wetland 1A is the largest and most hydrologically and botanically diverse wetland within the project area. It is a palustrine emergent wetland (PEM) dominated by wetland graminoids, particularly invasive reed canary grass (Phalaris arundinacea). Other observed wetland vegetation included immature green ash (Fraxinus pennsylvanica), calico aster (Symphyotrichum lateriflorum), wrinkle-leaved goldenrod (Solidago rugosa), cattail (Typha latifolia), fowl blue grass (Poa palustris), as well as various sedges (Carex spp.), rushes (Juncus spp.) and patches of silky dogwood (Cornus amomum). Several areas of invasive purple loosestrife (Lytrhum salicaria) were also documented within Wetland 1A. Soils within this wetland met the criteria for redox dark surface (USDA-NRCS, 2010) due to a layer that was greater than four inches thick but entirely within 12 inches of the mineral soil that had low value and low chroma and five percent redox concentrations (soft masses). The soil texture for this area consists of sandy -clay loam, although gravelly fill material is present within the first several inches of the soil profile (Appendix C). The boundary of this wetland was in many areas very difficult to establish due to subtle changes in vegetation and hydrology bordering on wetland/upland transition. It is likely that the plant and hydrological characteristics area are a result of the underlying soils (Scantic) and historical use of the area (tile drains, pasture). A small upland area containing common milkweed (Asclepias syriaca) was delineated near the center of this wetland, however several very small areas of upland are also present within the flagged wetland boundary within Area 1, but were not flagged. The portion of Wetland 1A within the 100-year floodplain is considered Wetlands of Special Significance (WoSS).

Wetland 1B Wetland 1B is a small, circular palustrine emergent (PEM) wetland situated in a small depression at the westcentral portion of Area 1. The vegetation is dominated solely by reed canary grass (Phalaris arundinacea). Soils within wetland 1B meet the criteria for depleted matrix (USDA-NRCS, 2010) due to a layer of high value and low chroma starting within ten inches of the soil surface. The soil texture for this wetland is silty clay loam (see Appendix C). Wetland 1C Wetland 1C is a palustrine emergent (PEM)/palustrine scrub-shrub (PSS) wetland located west of Wetland 1B (Figure 4). The wetland consists of a small depression situated at the base of the slopes leading to South Street and the access road in the southwest corner of the survey area. The PSS portion of the wetland is dominated by silky dogwood (Cornus amomum). The PEM portion is dominated by sensitive fern (Onoclea sensibilis) and jewelweed (Impatiens capensis). Other observed wetland plants in this area include fringed willowherb(Epilobium ciliatum), New England Aster (Symphyotrichum novi-angilae), and reed canary grass (Phalaris arundinacea). Soils within wetland 1C meet the criteria for depleted matrix (USDA-NRCS, 2010) due to a layer of high value and low chroma starting within ten inches of the soil surface. The soil texture for this wetland is silty-clay loam. Wetland 1D This wetland is located at the southeastern side of Area 1. The majority of the wetland is palustrine emergent (PEM) although the portion bordering the eastern property boundary is palustrine scrub-shrub (PSS). The emergent area is dominated by reed canary grass (Phalaris arundinacea) and the scrub-shrub area is dominated by silky dogwood (Cornus amomum). Soils within this wetland met the criteria for redox dark surface (USDA-NRCS, 2010) due to a layer that was greater than four inches thick but entirely within 12 inches of the mineral soil that had low value and low chroma and five percent redox concentrations (soft masses). The soil texture for wetland 1D is a silty clay loam. Wetland 2A Wetland 2A is a palustrine forested wetland (PFO) located in the east-central portion of Area 2. The wetland is in a depression at the base of single line drain 1. Green ash (Fraxinus pennsylvanica) and quaking aspen (Populus tremuloides) dominate the tree layer and silky dogwood (Cornus amomum) dominates the shrub layer. The herb layer is sparsely vegetated. Observed species include American cranberrybush viburnum (Viburnum trilobum), bristly dewberry (Rubus hispidus), and lady fern (Athyrium filix-femina).

Biddeford-Saco Wetland Delineation- October 2013

Soils for this wetland meet the criteria for redox depressions (USDA-NRCS, 2010) in that five percent redox concentrations occur in a layer more than two inches thick entirely within the upper six inches of the soil profile. Soil texture for this wetland is silt loam. Wetland 2B This wetland is a narrow, linear, palustrine scrub-shrub wetland situated mostly within the transmission line corridor. Single line drain 2 empties into and drains out of the wetland from the west and east, respectively. Single line drain 3 enters this wetland from the north. The shrub layer in the wetland is dominated by silky dogwood (Cornus amomum) and the herb layer is dominated by thyme-leaved speedwell (Veronica perphyllifolia) and jewelweed (Impatiens capensis). Sensitive fern (Onoclea sensibilis) and fringed willow-herb (Epilobium ciliatum) are also present. Soils for this wetland meet the criteria for redox depressions in that five percent redox concentrations occur in a layer more than two inches thick entirely within the upper six inches of the soil profile. Soil texture for this wetland is silt loam. 5.2 Wetlands of Special Significance Only the northern portion of Wetland 1A within the 100-year floodplain is considered a WoSS (Figure 3). Wetland 2A was documented as a potential vernal pool. Though the probability of significance is low due to short hydroperiod and a disturbed landscape, a spring survey is recommended to confirm that this area is not a WoSS. However, there has been no response to date from the MDIFW regarding significant wildlife habitat, which potentially could result in other areas being classified as WoSS. This is unlikely, however, due to the highly disturbed nature of the site. 5.3 Rivers, Streams and Brooks The Saco River meets the regulatory definition of a river; the south bank (top-of-bank) of the river was delineated. The three single line drains in Area 2 do not meet the definition of a river, stream or brook. 5.4 Potential Vernal Pools Wetland 2A is a sparsely vegetated depression that likely holds water for during a portion of spring and summer. However, due to its apparently short hydroperiod and surrounding urban landscape, it is highly unlikely that the wetland would meet the criteria to be considered a significant vernal pool. A spring vernal pool survey consisting of egg mass counts would be needed to confirm that the area does not function as a vernal pool.

6.0 SUMMARY OF RESULTS Six wetlands and the top of the south bank of the Saco River were delineated within the survey area. Characteristics of all wetlands, including hydrology, vegetation and soils have been significantly disturbed as a result of historical land uses including agriculture (hayfield, pasture, tile drains), residential development/use, and deposition of fill material from the water treatment facility. Several species of invasive plants were documented throughout Area 1 and 2 and along the bank of the river. A portion of one of the delineated wetlands (1A) met the criteria for Wetlands of Special Significance (WoSS); however, correspondence from MDIFW has not yet been received to determine if significant wildlife habitat exists at the site. In addition, wetland 2A was documented as a potential vernal pool. Though the probability of significance is low due to short hydroperiod and a disturbed landscape, a spring survey is recommended to confirm that this area is not a WoSS.

October 21, 2013 Denise Cameron Woodard & Curran 41 Hutchins Dr. Portland, ME 04102 RE: Information Request - Biddeford Saco Water Treatment Facility, Biddeford Dear Denise:

Per your requests received October 1 and October 16, 2013, we have reviewed current Maine Department of Inland Fisheries and Wildlife (MDIFW) information for known locations of Endangered, Threatened, and Special Concern species; designated Essential and Significant Wildlife Habitats; and fisheries habitat concerns within the vicinity of the two proposed sites of the Biddeford Saco Water Treatment Facility, located on the north and south sides of South Street in Biddeford. Findings for each category of protected resource are specified below. Rare, Threatened, and Endangered Species Our information indicates no locations of Endangered, Threatened, or Special Concern species within either parcel area. Essential Habitat Currently, Essential Habitat is designated only for Piping Plovers, Least Terns, and Roseate Terns, all of which are coastal breeding species and which do not occur in this area. Significant Wildlife Habitat The parcel located on the south side of South Street bisects a Deer Wintering Area, a Significant Wildlife Habitat identified under the Natural Resources Protection Act. Depending on what activities are proposed and how they are designed, development here could impact deer wintering habitat. Forestry regulations should be closely adhered to and the attached guidelines for managing Deer Wintering Areas should also be followed. Please contact, Brad Zitske, MDIFW Region A Wildlife Biologist (657-2345) for additional information and to discuss project details. At this time, Significant Vernal Pools have not been mapped within either parcel area. A comprehensive statewide inventory for Significant Vernal Pools, however, has not been completed at this time. Vernal pool surveys may need to be conducted prior to project design to verify the presence or absence of

Significant Vernal Pools. Once surveys are completed, our Department will need to verify vernal pool data sheets prior to final determination of significance. Fisheries habitat concerns The parcel on the north side of South Street is located adjacent to the Saco River, which supports wild brook trout. Best Management Practices should be closely followed to avoid erosion, sedimentation, and other impacts to the river habitat. This consultation review has been conducted specifically for known MDIFW jurisdictional features and should not be interpreted as a comprehensive review for the presence of other regulated features that may occur in this area. Prior to the start of any future site disturbance we recommend additional consultation with the municipality, and other state resource agencies including the Maine Natural Areas Program and Maine Department of Environmental Protection in order to avoid unintended protected resource disturbance. Please feel free to contact my office if you have any questions regarding this information, or if I can be of any further assistance. Best regards,

John Perry Environmental Review Coordinator

October 25, 2013 Lauren Swett Woodard & Curran 41 Hutchins Drive Portland, ME 04102 Re: Rare and exemplary botanical features in proximity to: Biddeford & Saco Water Treatment Facility, south of South Street, Biddeford, Maine Dear Ms. Swett: I have searched the Natural Areas Programâ&#x20AC;&#x2122;s Biological and Conservation Data System files in response to your request received October 24, 2013 for information on the presence of rare or unique botanical features documented from the vicinity of the alternatives analysis location south of South Street in Biddeford, Maine. Rare and unique botanical features include the habitat of rare, threatened, or endangered plant species and unique or exemplary natural communities. Our review involves examining maps, manual and computerized records, other sources of information such as scientific articles or published references, and the personal knowledge of staff or cooperating experts. Our official response covers only botanical features. For authoritative information and official response for zoological features you must make a similar request to the Maine Department of Inland Fisheries and Wildlife, 284 State Street, Augusta, Maine 04333. Our comments of September 26, 2013 are the same provided the facility is located north of the transmission line in the parcel south of South Street. The southern area of this parcel intersects with an exemplary natural community, a Red Maple Swamp. If you are planning work in the southern portion of the parcel, we would want to look at details of the project to provide recommendations. For more information about red maple swamps in Maine, please visit our website, http://www.maine.gov/doc/nrimc/mnap/features/communities/redmapleswamp.htm.

This finding is available and appropriate for preparation and review of environmental assessments, but it is not a substitute for on-site surveys. Comprehensive field surveys do not exist for all natural areas in Maine, and in the absence of a specific field investigation, the Maine Natural Areas Program cannot provide a definitive statement on the presence or absence of unusual natural features at this site.

The Natural Areas Program is continuously working to achieve a more comprehensive database of exemplary natural features in Maine. We would appreciate the contribution of any information obtained should you decide to do field work. The Natural Areas Program welcomes coordination with individuals or organizations proposing environmental alteration, or conducting environmental assessments. If, however, data provided by the Natural Areas Program are to be published in any form, the Program should be informed at the outset and credited as the source. The Natural Areas Program has instituted a fee structure of $75.00 an hour to recover the actual cost of processing your request for information. You will receive an invoice for $150.00 for our services. Thank you for using the Natural Areas Program in the environmental review process. Please do not hesitate to contact me if you have further questions about the Natural Areas Program or about rare or unique botanical features on this site. Sincerely,
