SECTION 1: PROJECT NARRATIVE 1.1
CONCISE STATEMENT OF THE PROBLEM
Dudley Pond is an 84-acre Great Pond located in the SuAsCo Basin, a FFY 2010 priority basin for 604(b) grant funding. Dudley Pond is on the Massachusetts 2008 Integrated List of Waters as Category 5 “Water Requiring a TMDL” for organic enrichment/ low dissolved oxygen, turbidity, and exotic species. Algal blooms fueled by watershed nutrient sources regularly impair pond uses throughout the summer. Eurasian milfoil is also serious problem for the Pond that significantly impairs its ecological and recreational values. The proposed project will complete a water quality assessment and TMDL for Dudley Pond, which the Town will use as the basis for landscape fertilizer and septic system regulations for the Pond watershed, and for evaluation of physical infrastructure improvements. The Town of Wayland Surface Water Quality Committee (SWQC) and the Dudley Pond Association (DPA) have worked continuously over the past decade to mitigate water quality impairments using both in-lake and watershed Best Management Practices. Despite ongoing these ongoing efforts, funding has not been available for a comprehensive assessment of Dudley Pond’s water quality and trophic status since the 1983 Dudley Pond Diagnostic/Feasibility (IEP, Inc) was completed 27 years ago. The proposed project will provide a long overdue update on pond water quality and provide the Town with information critical to the proper management of this important ecological and recreational resource. Examples of recent management efforts within Dudley Pond and its watershed include: 106 leaching catch basins were installed during the 1990’s throughout the Dudley Pond watershed, reducing direct stormwater discharges to the Pond. The Town regularly cleans all of the 150 catch basins in the watershed. In 1995, a pilot program was conducted to test the effectiveness of milfoil hand harvesting techniques, including diver hand-pulling and suction harvesting. Another diver hand-harvesting effort was conducted in 2002. In 2003, a Drawdown feasibility study for Dudley Pond was conducted by ENSR. Drawdown was determined to be infeasible, due primarily to the Pond’s slow rate of refill. Sonar (fluridone) treatments were conducted in 1992, 1999, 2003 and 2007 to provide relief from the serious Eurasian milfoil infestation impeding swimming, boating and fishing over much of the Pond. It is an important goal of the Town and the Dudley Pond Association to reduce the need for costly and repeated herbicide applications. A large bioretention cell and swale were constructed in 2007 to infiltrate and treat runoff from Wayland Middle School into Dudley Brook, Dudley Pond’s primary surface tributary. This Section 319 grant-funded project also included the stocking of milfoil weevils (Eurhychiopsis lecontei) in the Pond for Eurasian milfoil control. In 2007, the Town funded a study titled Nutrient Loading Assessment for Three Ponds in Wayland, MA, which included dry and wet weather sampling of tributaries to Dudley Pond. 1
In 2007 the Town purchased three pond circulators and performed testing during 2007, 2008 and 2009 to determine the effectiveness of pond circulators as a tool to manage milfoil and improve water clarity. Hand pulling in resulted in the removal of more than 6,000 milfoil root crowns in 2008 and 18,000 rooted plants in 2009. As summarized above, a significant ongoing effort has been maintained by the Town and the DPA to manage nuisance algae and aquatic vegetation at Dudley Pond. These impairments are symptoms of eutrophication accelerated by excessive nutrient sources from the Pond watershed and internal recycling of nutrients from the Pond’s sediments. The proposed water quality assessment and TMDL development will provide important tools for the long-term management of the Pond’s nutrient sources, allowing the Town to (1) focus resources on the sources of water quality impairments, (2) reduce expenditures on treating the symptoms, and (3) work to develop new regulatory tools for improved watershed management.

CONSISTENCY WITH EOEEA WATERSHED ACTION PLANS
The proposed project directly addresses two priority action items identified in the EOEEA 2005 SuAsCo Watershed Action Plan (WAP), as described below: Section 5 (page 5-5) of the WAP states that is a priority for the watershed to “conduct TMDL studies by tributary watershed, where necessary, and implement the results of all TMDL studies. A major deliverable for this project is completion of the EPA-required TMDL for Dudley Pond. Section 5 of the WAP also recommends the creation of “local bylaws to minimize use of lawn fertilizers, pesticides, and herbicides”. The Town will use development of a TMDL as a critical first step to reducing nutrient loading to Dudley Pond. The TMDL will be used to justify watershed regulations for fertilizer use and septic system inspection and maintenance, and to provide a scientific basis for infrastructure improvements. 1.3
APPROACH TO THE PROBLEM
The proposed project will provide: 1. A comprehensive assessment of in-lake and tributary conditions for Dudley Pond, including development of a nutrient budget and associated water quality model for Dudley Pond; 2. An assessment of land-use and nutrient loading issues in the Dudley Pond watershed; 3. Development of an EPA- and DEP-approved TMDL for Dudley Pond; and 4. Public outreach and education of the project results. A summary of the approach to these project elements is provided below, followed by a detailed Scope of Services in Section 2. The Town will coordinate the activities of its proposed consultant (Geosyntec Consultants) through the Wayland Surface Water Quality Committee. LITERATURE AND DATA REVIEW Geosyntec will conduct a literature and data review of past studies and water quality monitoring related to Dudley Pond. Based on this review, Geosyntec will provide a written summary of past studies. ASSESSMENT OF IN-LAKE AND TRIBUTARY CONDITIONS In-lake and Tributary Water Quality Monitoring: In conformance with a project QAPP, a five-month monitoring program will (1) provide an updated baseline assessment of in-lake and tributary water quality and (2) support development of a nutrient loading budget and Vollenweider model for the Pond. To allow for collection of monitoring data that reflects wet weather conditions, two of sampling events will be conducted during storm events. Additional tributary sampling data for Dudley Pond is also available from the recent Watershed Nutrient Loading Assessment for Three Ponds in Wayland, MA (Geosyntec, 2007) project. Algae Sampling: Phytoplankton will be sampled at the lake deep hole in early June, early August and late October for enumeration and species identification. Aquatic Vegetation Survey/Mapping: A detailed survey and mapping of the aquatic vegetation in Dudley Pond will be conducted. A written assessment and map of the lake's macrophyte community will be provided, including recommendations on long-term management of the macrophyte community in Dudley Pond.

PHOSPHORUS LOADING ANALYSIS AND VOLLENWIEDER MODEL Land Use Model: A land-use pollutant loading model will be used to estimate annual phosphorus export from subwatersheds within the Dudley Pond watershed. The land-use model will provide a comparative measure of the relative impact that each subwatershed has on pond water quality, and will help in prioritization of sites for watershed improvements. Phosphorus Loading Budget: An estimate of Dudley Pond’s annual phosphorus loading budget and trophic status will be derived from analysis of water quality data, groundwater sources (including septic systems), atmospheric sources, internal nutrient recycling from lake sediments, and the estimates derived from the land use pollutant loading model described above. The loading budget will be calibrated with water quality data derived from the water quality sampling program described under Task 2-1. Vollenweider Equation: A Vollenweider equation will be used to calculate estimated in-lake phosphorus concentrations for Dudley Pond based on the phosphorus loading budget, the pond’s hydraulic residence time and other data. TMDL DEVELOPMENT Based on the water quality data, phosphorus loading budget and Vollenweider equation described above, Geosyntec will develop a TMDL and target goal for reducing the volume of annual phosphorus loading to Dudley Pond. The format of the TMDL will be based on discussions and coordination with DEP staff, and will be generally consistent with existing lake and pond TMDLs that have been prepared by DEP (e.g. Indian Lake, Leesville Pond, etc.). A draft TMDL will be prepared for EPA and DEP review. A final TMDL will then be prepared based on comments received from EPA and DEP on the draft. WATERSHED SURVEY A field investigation of the Dudley Pond watershed will be conducted to (1) document sources contributing sediment and nutrients to the Pond and (2) identify sites for improvements, such as stormwater retrofits, installation of Low Impact Development (LID) practices, stabilization of eroding areas, on-site wastewater upgrades, etc. Based on the watershed survey and review of other data sources, Geosyntec will develop recommendations for watershed nutrient loading improvements that will be presented in the “Implementation” section of the TMDL. PUBLIC OUTREACH / TMDL PUBLIC PARTICIPATION Project Website: A project website will allow the public and all project stakeholders to access all project-related reports and documents. The website will provide a convenient method for review of draft reports and other deliverables described within the Scope of Services. Public Meeting: The WSWQC and Geosyntec will host a public meeting to present the project results in a PowerPoint presentation format. The meeting will be coordinated with Town Boards and Commissions and will be promote public consensus-building on the pond restoration recommendations included in the Plan. Public Education Materials: The Wayland SWQC will develop and distribute public materials on the results of the project, including a brochure and a septic system operations and maintenance document. A detailed Scope of Services for the tasks described above is provided on the following pages. 4
SECTION 2: SCOPE OF SERVICES TASK #1: QUALITY ASSURANCE PROJECT PLAN Geosyntec will develop a DEP- and EPA-approved Quality Assurance Project Plan (QAPP), which will govern protocols for water quality, sediment and aquatic vegetation sampling conducted to evaluate project results. A draft version of the plan will be submitted for DEP and EPA review and comments. Based on the comments received on the draft QAPP, Geosyntec will develop and submit a final QAPP for the project monitoring tasks. TASK 1 DELIVERABLES: A DEP- and EPA-approved QAPP. COST: $2,443
TASK #2: ASSESSMENT OF IN-LAKE AND TRIBUTARY CONDITIONS Task 2-1: Literature and Data Review Geosyntec will conduct a literature and data review of past studies and water quality monitoring related to Dudley Pond. Geosyntec will provide a written summary and analysis of the past studies. Task 2-2: Water Quality Monitoring A water quality monitoring program will be conducted in conformance with the DEP-approved QAPP described under Task #1. Monitoring will be conducted on monthly basis from May to September during the first year of the project (if feasible based on the contract authorization date), for a total of five (5) sampling events. To allow for collection of tributary monitoring data reflecting wet weather conditions, two of the monthly sampling events will be conducted during storm events. Water quality monitoring will be conducted at the following tributary and in-lake locations (Figure 2): Confluence of Tributary #1 and Dudley Pond; Dudley Pond “deep hole�; Dudley Pond outlet; and Four storm water outfall pipes (when flowing).

Deep Hole Tributary #1
A multi-parameter in-situ water monitoring instrument will be used to establish a water quality profile for the Pond’s deep hole sampling location, with measurements recorded for each parameter at 0.5meter intervals. Nutrient samples will be obtained (for analysis at a Massachusetts-certified laboratory) with a Kemmerer sampler at the surface, middle and bottom of the water column at the deep hole. Chlorophyll-a samples will be taken from the deep hole location with a tube sampler. Monitoring for all parameters except chlorophyll-a will be conducted just below the water surface for the tributary and outlet monitoring sites. Monitoring will be conducted at each sampling station for the following parameters: pH; Temperature; Dissolved oxygen; Specific conductance; Nutrients: Ortho-phosphorus, total phosphorus, Kjeldahl-N, Ammonia-N (lab); Chlorophyll-a (deep hole only); and Secchi disk water clarity (deep hole only). Additional sampling for total phosphorus only will be conducted at the four storm water outfall 6
locations (see Figure 2) when flowing during wet weather sampling or if observed flowing during any other sampling event. All field data will be presented in tabular or graphic formats in a report, along with a GIS map depicting all sampling locations. All field data, including mapping data will be delivered in electronically readable forms. Based on the monitoring program described above, the report will also include Geosyntec’s assessment of Dudley Pond’s trophic status, potential impairments, and provide recommendations for future monitoring. Task 2-3: Algae Sampling and Analysis On three of the proposed water quality sampling dates, a phytoplankton sample will be collected from the deep hole sampling location for enumeration and species identification. Geosyntec will present the laboratory data in a table and provide a narrative description of the sampling results. Algae sampling is proposed for early June, early August and late October, to allow for assessment of seasonal trends in algal abundance and species composition. Task 2-4: Aquatic Vegetation Survey In conformance with the QAPP described under Task #1, an aquatic vegetation survey will be conducted to provide updated information on the macrophyte community within Dudley Pond during the height of the growing season (July/August). Aquatic vegetation will be sampled from a boat. Plant species will be identified both by visual inspection and by using an aquatic vegetation grappling hook to sample submerged vegetation. Emergent wetland species growing within Dudley Pond will also be identified. All plant species identified will be recorded on a tally sheet that will be provided as part of the final report. An aquatic vegetation maps will be developed using GIS software and will provide information in a format that is consistent with the MassDEP aquatic macrophyte survey standards, including: (1) species identification; (2) bio-volume estimates; and (3) an estimate of aerial coverage throughout the lake. A minimum of forty (40) pre-determined locations throughout the lake’s littoral zone will be sampled for all plant species present, with the dominant plant(s) also noted. A running documentation of dominant plant(s) throughout the littoral zone will also be recorded. Particular emphasis during the vegetation survey will be also placed on documenting the location and dominance of any invasive, non-native plants. TASK 2 DELIVERABLES: A water quality monitoring report including data analysis, assessment of Dudley Pond’s trophic status, potential impairments, and recommendations for future monitoring; Phytoplankton sampling for enumeration and species identification at the pond deep hole on three dates, including a final report section on the sampling results; and An aquatic vegetation survey, with supporting maps and information on the distribution and dominance of macrophytes in Dudley Pond; COST: $12,653

TASK #3: PHOSPHORUS LOADING ANALYSIS AND VOLLENWIEDER MODEL Task 3-1: Land Use Model Based on the data collected by Geosyntec under Task 2, Geosyntec will develop an assessment of inpond phosphorus concentrations and the pond’s trophic status. Geosyntec will also conduct land-use based modeling to estimate annual phosphorus export from subwatersheds within the Dudley Pond watershed. MassGIS land-use data and associated land-use export coefficients will be used to model the watershed’s current land-use and external pollutant loading. Land use based exports are an average measure of pollutant export for specific land use categories. These data will be used in a land-use based pollutant model to predict annual phosphorus loading from each subwatershed. The results of the land-use loading model will be presented in table format and Geosyntec will also provide a written description of the predicted phosphorus loading and dominant land uses within each of the subwatershed areas. The land-use based pollutant loading model provides a tool for estimating and comparing (1) total annual pollutant loads (2) annual pollutant load rates normalized to the watershed for each subwatershed. This type of land-use model cannot be used to accurately predict in-lake conditions (e.g., in-lake total phosphorus concentrations) because it does not reflect site-specific land management practices or other variables such as internal nutrient recycling, lake volume, etc. However, the land-use pollutant loading model estimates do provide a useful comparative measure of the relative impact that each subwatershed has on lake water quality, and therefore are a useful tool to prioritize sites for watershed improvements. Task 3-2: Phosphorus Loading Budget To estimate the Dudley Pond annual phosphorus loading budget, Geosyntec will assess groundwater sources (including septic systems), atmospheric sources, internal nutrient recycling from lake sediments, and the estimates derived from the land use pollutant loading model described above. The loading budget will also be calibrated with water quality data derived from the proposed water quality sampling program described under Task 2-1. The estimated annual phosphorus budget will be used to develop the Vollenweider equation described below. Task 3-3: Vollenweider Equation Estimate of In-lake Phosphorus Concentrations The Vollenweider equation is commonly used to predict in-lake phosphorus concentrations as a function of annual phosphorus loading, mean lake depth and hydraulic residence time. The Vollenweider equation will be used to calculate an estimated in-lake P concentration for Dudley Pond based on phosphorus loading data from proposed water quality monitoring program, and the land use model. The Vollenweider model will also be used to derive a target goal for reducing the volume of annual phosphorus loading to Dudley Pond. TASK 3 DELIVERABLES: A land use-based phosphorus loading model for the Dudley Pond watershed and its subwatersheds, as described above; A phosphorus loading budget calibrated with water quality data, as described above; and A Vollenweider equation for Dudley Pond, target phosphorus concentration goal and target reduction in annual phosphorus loading. COST: $5,446

TASK #4: WATERSHED ASSESSMENT TASK 4 DELIVERABLES: A field investigation of the Dudley Pond watershed will be conducted to (1) document sources contributing sediment and nutrients to the Pond and (2) identify sites for stormwater improvements, such as retrofits to existing structures, installation of Low Impact Development (LID) practices to increase infiltration and nutrient attenuation, and stabilization of areas where erosion is contributing sediment to the Pond and its tributaries. Based on the watershed survey and review of other available data sources, Geosyntec will develop a list of recommendations for stormwater management improvements and other nutrient load reductions in the Dudley Pond watershed. This information will be presented in narrative and table format in the “Implementation� section of the Dudley Pond TMDL. COST: $7,814 TASK #5: DEVELOP TMDL FOR DUDLEY POND Based on the water quality data, phosphorus loading budget and Vollenweider equation described above, Geosyntec will develop a TMDL and target goal for reducing the volume of annual phosphorus loading to Dudley Pond. The format of the TMDL will be based on discussions and coordination with DEP staff, and will be generally consistent with existing lake and pond TMDLs that have been prepared by DEP (e.g. Indian Lake, Leesville Pond, Lake Quinsigamond/Flint Pond, etc.), including the following sections: Executive Summary Introduction General Background and Rationale Waterbody Description and Problem Assessment Pollutant Sources and Background Water Quality Standards Violations TMDL Analysis Loading Capacity Wasteload Allocations, Load Allocations and Margin of Safety Implementation Reasonable Assurances Water Quality Standards Attainment Statement Monitoring Public Participation Public Comment and Reply References Tasks related to public participation and public comment/reply are described below under Task 6. TASK 5 DELIVERABLES: A draft TMDL will be prepared for EPA and DEP review. A final TMDL will then be prepared based on comments received from EPA and DEP on the draft. COST: $12,548 9
TASK #6: PUBLIC OUTREACH / TMDL PUBLIC PARTICIPATION TASK 6 DELIVERABLES: Project Website: A project website will allow the public and all project stakeholders to access all project-related reports and documents. The website will provide a convenient method for review of draft reports and other deliverables described within the Scope of Services. Public Meetings / TMDL Public Participation: Upon completion of the draft Water Quality Assessment and TMDL, the Town and Geosyntec will host a public meeting in coordination with DEP staff to present the draft TMDL to local government representatives, the Dudley Pond Association, and other interested parties. The draft TMDL will also be announced in the Environmental Monitor for public review and comment. A second public meeting will be held to present the final draft TMDL and provide a forum for public comment. Geosyntec will compile a list of all attendees at the public meetings for inclusion in the final TMDL as an appendix. Reply to Public Comments: The final TMDL for Dudley Pond will include a section that summarizes and provides responses to comments provided at the public meetings and in writing. Where appropriate, the final TMDL will incorporate revisions and additional information in response to the public comments received. Public Education Brochure: The Wayland SWQC will develop and distribute public materials on the results of the project, including a two-page, six panel, color educational brochure and a multipage septic system operations and maintenance document. These materials will be mailed to watershed residents, distributed at the Town Offices, and made available for in downloadable form on the Project Website. These public education materials will be prepared and distributed as an in-kind service from the Town at no cost to the project. COST: $5,040
TASK #7: REPORTING The Town of Wayland will prepare quarterly progress reports for the duration of the project, summarizing all work completed and activities planned for the next quarter. Regular invoices will submitted according to the required form. A Final Draft report will be submitted to DEP, including all of the analyses, maps and other deliverables as described above under Tasks 1-6. Based on DEP's comments on the Final Draft, a Final Report will be completed and submitted to DEP in both hard copy and electronic formats.
