City of Sumner SWMP 2013

INTRODUCTION

The National Pollutant Discharge Elimination System (NPDES) permit program is a requirement of the Federal Clean Water Act. The Phase I and Phase II municipal stormwater permits were initiated to protect water quality through the development and implementation of programs and procedures designed to regulate, detect and eliminate pollutant discharges. The Federal Environmental Protection Agency (EPA) has delegated permit authority to state environmental agencies towards developing, implementing and enforcing stormwater regulations and policies. In Washington State, the NPDES-delegated permit authority is the Washington State Department of Ecology (Ecology).

1.1 PERMIT BACKGROUND

The first cycle of NPDES municipal stormwater permits were issued by Ecology in January of 2007 to Phase I and Phase II jurisdictions. Ecology designated Phase I Permitees as jurisdictions with a population of 100,000 or greater and Phase II Permitees as jurisdictions with population of less than 100,000 according to the 1990 census. Phase II communities were required to complete an NPDES Phase II Stormwater Permit Application and submit to Ecology by March 10, 2003. The first cycle of NPDES Phase II Permits (Permit) were issued to Sumner on January 17, 2007 and went into effect for a 5-year term on February 16, 2007. In June 2009 the permits were modified to reflect changes made in response to a multijurisdictional appeal of the Permit. The first cycle of permits expired in June of 2012 but remained in effect until the next permit was issued August 1st, 2012. This second permit will remain in effect for a 1- year permit term at which point the second 5-year cycle of permits will become effective, August of 2013.

1.2 STORMWATER MANAGEMENT PLAN (SWMP)

This document, known as the Stormwater Management Plan (SWMP) describes the annual programs and plans to be implemented in compliance with the NPDES Phase II municipal stormwater permit (Phase II Permit). The SWMP is updated annually by the City of Sumner to meet the requirements of the Phase II Permit. The SWMP was developed to outline the City’s advancement and strategy for implementing Permit required programs and policies. The SWMP also illustrates the City’s individual approach towards the reduction of pollutant discharges from the City’s Municipal Separate Storm Sewer System (MS4). The overall purpose of this program is to protect water quality by reducing pollutant discharges to the maximum extent possible (MEP). This will be accomplished through proper education, program development, the application of Best Management Practices (BMP’s) and compliance

City of Sumner SWMP 2013 with Washington State’s All Known and Reasonable Treatment (AKART) requirements where applicable in the major divisions of the NPDES Permit listed below: • • • • •

Public Education and Outreach Public Involvement and Participation Illicit Discharge Detection and Elimination Controlling Runoff from New Development, Redevelopment and Construction Sites Pollution Prevention and Operation and Maintenance for Municipal Operations

The Phase II Permit requires a comprehensive annual report describing completed requirements and deadlines for future requirements. This report must be submitted to the Ecology, by March 31st of the following year. The SWMP document is an element of the annual report that provides an explanation of the Permit requirements and previous year’s activities as well as a summary of potential plans based on future requirements of the Permit in the forthcoming years. An updated SWMP is required with each year’s annual report to Ecology.

1.3 FUTURE PERMIT (2013-2018)

Sumner is defined as a Phase II community by the Washington State Department of Ecology (Ecology), and therefore, is required to comply with the requirements of the NPDES Phase II Permit. Phase II communities are those that: •

Own and operate a storm drain system.

•

Discharge to surface waters.

•

Are located in urbanized areas.

•

Have a population of more than 1,000 but less than 100,000.

In 2011, a legislative alteration lead Ecology to reissue the (2007-2012) Phase II Permit unchanged, for one additional year. This Permit is currently in effect until August 2013 at which point the next 5-year cycle permit becomes active. Ecology worked with other interested parties to developed draft permits through a permit reissuance process that began in the summer of 2008. A 3-month public comment period ending February 3, 2012 was provided to allow jurisdictions the opportunity to provide constructive feedback on new permit requirements. Ecology reviewed the comments submitted and incorporated changes where applicable to final permits. Currently there is a 1year and a 5-year Phase II Permit that was issued on August 1, 2012 and August 1, 2013 respectively. Section G18 of the permit required Phase II jurisdictions to reapply for coverage under the new Permit by submitting a Duty to Reapply Notice of Intent (NOI) application. Permittees were required to complete this task 180 days prior to the expiration of the last Permit cycle.

NPDES PHASE II PROGRAM COMPONENTS

The Phase II Permit is a booklet of defined special and general conditions designed to guide and direct Permittees in developing stormwater code, policies and programs. These programs focus to educate, promote and enforce water quality standards within their jurisdiction. The Phase II Permit contains several sections and subsections pertaining to program requirements and protocol. The following list describes the 6 core programs of the current Phase II Permit and new Monitoring section that will be a part of the future (2013-2018) Permits: • • • • • •

The additional section for monitoring will not become effective until August of 2013 when the new Phase II Permit will be issued. The City of Sumner is currently exempt from monitoring requirements due to criteria requiring a population greater than 10,000. The requirements of these program components and how the City of Sumner is currently addressing and plans to address future requirements are discussed in greater detail in the following sections. In general, the City of Sumner has activities and programs in place that meet current NPDES Phase II Permit requirements. As future requirements are introduced, the City will need to develop and implement additional programs, training, educational materials, and update policies and procedures to manage current specifications and demands.

PUBLIC EDUCATION AND OUTREACH

2.1.1

Permit Requirements

This component aims to implement a public education program that actively provides educational materials, learning opportunities, and activities regarding stormwater management to the community. More specifically, this program focuses to distribute significant and applicable stormwater information to various audiences including: the general public, businesses, homeowners, engineers, contractors and City staff. The messages in these materials contain a general theme concerning the impacts of stormwater discharges on local and regional water bodies. These materials can be distributed in an assortment of ways including but not limited to: seminars, trainings, events, commercials, online postings, newsletters, posters, coloring books and brochures. A portion of this program focuses on providing informative methods and behaviors the general public can adopt to reduce the amount of pollutants in stormwater runoff generated from the homeowner. Other segments focus on business and property management, maintenance of stormwater facilities, and hazardous materials. The education program targets a variety of groups, in an effort to contact and inform a large percentage of those most likely to impact stormwater. To ensure that the program is successful, a measurement of the behaviors and understanding of water quality was recorded after a regional survey developed in conjunction with Pierce County was administered to the citizens of Sumner. The data and results provided will be used as a baseline to guide future public education and outreach programs. Additional surveys will be administered intermittently to determine whether or not the current methods of informing the public are effectively educating and reducing pollutant discharge. This program promotes a positive change in behaviors to ensure and protect water quality in local and regional waters of the state. 2.1.2

Public Education Activities

The City of Sumnerâ&#x20AC;&#x2122;s public education program addresses the requirements identified in the Public Education and Outreach component of the Permit. Annual requirements have been met in the past through the implementation of the following activities:

Sumner policy requires that stormwater control facilities, serving other than singlefamily residential developments, be owned and maintained by the homeownersâ&#x20AC;&#x2122; association, property owner or other designee. The developer is required to execute and record an Agreement to Maintain Stormwater Facilities and to Implement a Pollution Source Control Plan in instances where the City will not assume ownership and maintenance of a stormwater facility.

City of Sumner SWMP 2013

The City of Sumner entered into contract with the Washington State Department of Ecology to start a Local Source Control Program. This program entailed hiring an employee to conduct site inspections of local small quantity generator businesses, regarding hazardous waste maintenance and disposal. The Local Source Control Specialist documents potential issues identified during the inspections and provides technical assistance to local business managers.

The City maintains a list of Stormwater Maintenance Agreement holders and conducts inspections of the businesses stormwater facility with property managers or maintenance staff. Proper maintenance and repairs are explained during the walkthrough inspection of the facility with the intent of improving the water quality of their facilities discharge.

The City’s Community Connection Newsletter often provides articles on various stormwater public education topics.

The police department at City Hall has a bin to accept expired prescription drugs. Information about the take-back program is distributed to local pharmacies to post. The City also hosts a spring clean-up event and offers take-back bins during the event.

Continued the promotion of using “Bonney Good Sumner Grow” biosolids from the Waste Water Treatment Facility as a slow release nitrogen fertilizer for plants and landscape vegetation.

The City of Sumner developed a fertilizer poster to assist local gardeners in reducing the chances of over fertilizing and creating toxic runoff. The poster is made available online at City Hall and some local nurseries.

The City of Sumner continues collaboration with Pierce County to acquire and distribute coffee sleeves for distribution at local coffee stands during the month of May for Puget Sound Starts Here (PSSH) Month. Each coffee sleeve was designed with specific stormwater messages for the common home owner.

Pet waste bag dispenser stations are located at Parks and trail sections for pet owners to learn and properly dispose of pet wastes.

The City of Sumner continues to promote the use of the City’s Carwash Kit. The kit is made available for check-out to the local residents and businesses in the area.

PUBLIC INVOLVEMENT AND PARTICIPATION

2.2.1

Permit Requirements

This program component requires that the City of Sumner develop a public involvement and participation program that complies with state and local public notice requirements. The City of Sumner currently participates in various groups and organizations pertaining to the importance of water quality and future issues. The City also has a program available for the public to partake in the development and formation of this SWMP. 2.2.2

Public Involvement and Participation Activities

The City of Sumner has a public involvement and participation program in place that meets requirements of this program component, by providing opportunities for the public to learn, comment or propose suggestions regarding stormwater projects, programs and policy.

The City has been a member of the Puyallup River Watershed Council (PRWC) for several years. This group works to coordinate water quality programs, activities, and organizes discussions concerning environmental and habitat issues in the Puyallup River basin.

Another environmental organization the City has partnered with is Puget Sound Starts Here (PSSH). This group focuses on promoting stormwater tips for the homeowner in several categories such as: natural yard care, car maintenance and washing, and pet waste. The City utilizes the promotional materials provided by PSSH to propagate the same messages creating a regional effort to reduce pollutants from entering the water systems of Puget Sound.

The Community Development Department has formed its own program called Sumner University. This curriculum presents information regarding local government, giving the citizens of Sumner the opportunity to learn discuss various departments and programs in their jurisdiction. A portion of this presentation includes information on our stormwater program.

During the Puyallup Fair, City staff manned a booth for Pierce Conservation Districts Stream Team Program. Staff provided answers to questions from Fair guests regarding the Rain Barrel and permeable demonstrations and other displays. Children were asked if they wanted to feed Sammy the Salmon, in an effort to educate the youth on salmon habitat and how they directly impact their quality of living environments.

The City is also an active member of the South Puget Sound Phase II Coordinatorâ&#x20AC;&#x2122;s Group. This organization meets bi-monthly to discuss stormwater related issues and address

11 of 27

City of Sumner SWMP 2013 methods of compliance regarding NPDES Permit deadlines. A continuous focus for this group is public education.

Another group the City has become affiliated with is the Stormwater Work Group (SWG). This group met quarterly to discuss specific topics of the overall plan to provide Ecology with a proposal for a regional monitoring system that would satisfy the monitoring requirements of the Permit. In October of 2010 the SWG provided recommendations and comments pertaining to new Permit requirements regarding a regional monitoring program. Most of the recommendations were implemented into the draft version of the next NPDES Phase II Permit. The group continues to work with Ecology on the development of the effectiveness monitoring program, updating the 2012-2013 work plans, overseeing the processes for status and trends and pooling resources, and development of the repository for source identification information.

In addition to involvement in the PRWC, the South Puget Sound Phase II Coordinator’s Group, and the local caucus group, the City focuses extend stormwater education to industrial and commercial development through stormwater regulations requiring all industrial and commercial sites to paint or emboss “DUMP NO WASTE – DRAINS TO STREAM” adjacent to all storm drain inlets.

Sumner also has a public involvement and participation activity for car washes. The City has implemented the use of a car wash kit designed to collect waste water from car washes so that it can be pumped into the sanitary sewer system. There is also an informational handout for this activity in Appendix A.

Another organization the City collaborates with is Pierce Conservation Districts Stream Team. Various Capital Improvement and Trail Projects offer the opportunity to provide additional habitat restoration near the rivers and creeks of Sumner. The City utilizes Stream Teams expertise to efficiently organize volunteer events to complete environmental projects. The public has the continuous opportunity to aid in the development of the City’s SWMP through an online commentary. Citizens are encouraged via the online Stormwater webpage to read the SWMP and submit comments to the NPDES Permit manager. The SWMP, annual report(s) and other submittals are made available to the public on our City website. Comments are being addressed accordingly. 2.2.3

Future Public Involvement and Participation Activities

The City will post the updated versions of the SWMP and annual report on its website (www.ci.sumner.wa.us) by March 31st. Any other submittals required by the Permit will also be posted as necessary on the website. The public will continue to have the opportunity to comment on the SWMP by means of the contact information provided. The City also hosts

12 of 27

City of Sumner SWMP 2013 several council meetings for which the public can attend and voice their opinions on various stormwater projects. The City of Sumner has recently joined up with Citizens for a Healthy Bay (CHB) to organize a project called Puyallup River Pollution Patrol. This project gets students involved with water quality issues, teaching them about pH, turbidity and the effects on aquatic habitat and resources. In May, the City will distribute promotional coasters and coffee sleeves to local participating coffee stands to use and support stormwater messages provided by PSSH. The project goal is to generate awareness of PSSH and the information they provide concerning stormwater impacts and management. The City would also like to organize a stenciling project, likely with the assistance of CHB or Stream Team. Active involvement with the various groups and organizations as well as coordination between municipal departments will continue in support of protecting water quality. The City of Sumner plans to be a part of the EPA Puget Sound Watershed Management Assistance Grant in collaboration with the City of Puyallup and many other municipalities in the Pierce County region.

ILLICIT DISCHARGE DETECTION AND ELIMINATION

2.3.1

Permit Requirements

Compliance with this program component requires the City to implement and enforce an Illicit Discharge Detection and Elimination (IDDE) program for the City’s MS4. Required program elements are as follows: •

Develop a municipal storm sewer system map that includes information on the City’s MS4 (e.g. outfalls, receiving waters, connection points, areas that don’t discharge to surface water, etc.).

•

Effectively prohibit, through ordinance or other regulatory mechanism, non-stormwater, illegal discharges, and dumping into the City’s MS4.

•

Develop and implement a program to detect and address non-stormwater discharges, spills, illicit connections and illegal dumping into the City’s MS4.

•

Inform public employees, businesses, and the general public of hazards associated with illegal discharges and improper waste disposal.

•

Implement procedures for program evaluation and assessment which includes a program to track spills and illicit discharges (both number and type), record inspections made and record any feedback received from public education effort.

•

Provide appropriate training to City employees on IDDE into the City’s MS4.

2.3.2

Illicit Discharge Detection and Elimination Activities

The City’s Illicit Discharge Detection and Elimination Program works to minimize impacts of pollution entering the local water ways, by identifying pollutant substances, tracking down the source and eliminating the cause for water contamination. This program includes responding to spill situations and field screening.

The City of Sumner has a Municipal Separate Storm Sewer System (MS4) base map that is regularly updated by the City to include development and redevelopment projects upon completion and receipt of as-built information. Additional information is periodically provided by Pierce County (due to Interlocal agreement).

A supplementary map of the MS4s known outfall sites and structural BMPs owned, operated, or maintained has also been developed in response to Permit requirements. Other maps illustrate land uses, areas served by the MS4 and those that do not discharge surface waters.

14 of 27

City of Sumner SWMP 2013

The City provides training through the use of webinars and in-house training sessions to educate staff and field personnel regarding identification and elimination of various discharges, and procedures to remedy specific situations.

City crews respond to spill and/or accident situations to provide immediate containment and clean-up of pollutants from entering local waterways.

A phone hotline and email link is in place and currently displayed on our City website for citizens to use and report incidents. The number will either contact the City’s Maintenance and Operations Facility during business hours or the Police Department for after hours to respond.

Outfall reconnaissance and field inspections are conducted on a prioritized waterway. Sumner ordinances and other programs are in place and meet requirements for the IDDE component of the Permit. Sumner Municipal Code (SMC) and other programs currently in place concerning illicit discharge control are as follows: •

SMC 13.48.233 Illicit connection, this code defines an illicit connection according to the City

•

SMC 13.48.234 Illicit discharge, this code defines an illicit discharge according to the City.

•

SMC 13.48.820, Illicit discharges, this code prohibits illicit discharge.

•

SMC 13.48.830, Enforcement, this code defines how the City will enforce the codes.

•

SMC 13.48.860, Penalty, this code defines how the City will penalize failure to comply with the codes.

•

Nonpublic stormwater facility operators are required to execute and record an Agreement to Maintain Stormwater Facilities and to Implement a Pollution Source Control Plan as shown in Appendix C. Operation, maintenance and repair responsibility resides on the facility owner. Included in this plan is a maintenance checklist which contains line items regarding identification of oil and chemical sheens or odors. A database for properties possessing recorded Stormwater Maintenance Agreements has been created to monitor inspections, annual report submissions and maintenance/repair activities.

•

Stormwater Pollution Prevention Plans have been developed for Sumner-maintained streets, the Sumner WWTP, and the Sumner Meadows Golf Links. The golf course and WWTP plans state that dry weather surveys will be conducted annually for IDDE.

•

Illicit discharges to the Sumner storm system are detected during routine catch basin and stormwater conveyance system maintenance activities. Catch basin and stormwater conveyance cleaning is typically conducted on an as-needed basis.

City of Sumner SWMP 2013 â&#x20AC;˘

Documentation of activities including when inspections take place, times and types of spills, public feedback from education efforts and training for municipal staff has been implemented and recorded.

TOTAL MAXIMUM DAILY LOAD (TMDL) The Federal Clean Water Act requires each state to develop water quality standards with the intention of protecting and preserving water quality and water resources. Bi-annually, states are required to conduct water quality assessments and develop a list of water bodies that fail to meet water quality standards. This list is called the 303(d) list. The Clean Water Act requires a Total Maximum Daily Load be formed for all waterbodies on the 303(d) list. The ultimate goal of the TMDL is identify causes of pollution and eliminate or reduce these sources and re-establish water quality standards. The Department of Ecology identified several waterbodies within the Puyallup River Watershed that do not currently meet water quality standards for Fecal Coliform and thus have developed a TMDL for the watershed. The City of Sumner is working with Ecology and other local jurisdictions to reduce the impacts of local waterways and the overall quantities of Fecal in the Watershed. The City conducts water quality assessments and utilizes the IDDE program to identify potential contributing sources of Fecal Coliform and eliminate these sources.

2.3.3

Future Illicit Discharge Detection and Elimination Activities

The City continues its ongoing program to detect Illicit Discharges and Illicit Connections of the MS4, train staff to document illicit connections and spills as well as continue investigations for sources of fecal coliform in Salmon Creek. Staff will continue training in performing field assessments and visual inspections of high priority outfalls and water bodies in preparation for regulated monitoring of receiving waters and source identification. The planned activities stated earlier for public education and outreach will continue to provide information on IDDE in an effort to decrease the number of illicit discharges and connections found throughout the City. In response to the TMDL report developed by Ecology in June 2011, the City of Sumner has initiated an investigation on Fecal Coliform sources discharging to Salmon Creek. Water samples from various locations on the Creek have been tested to determine the location(s) of the significant contributors (source identification). The process of sampling and identifying potential sources of pollution will continue until Ecology determines the waters of Salmon Creek meet water quality standards. Outfall screening activities will continue on at least one high priority water body.

16 of 27

City of Sumner SWMP 2013 The City will continue to develop its map of the MS4 including the locations of all known stormwater outfalls and structural BMPâ&#x20AC;&#x2122;s. Methods for locating and tracking areas with a higher probability for having illicit discharges will be developed. The City will also continue to develop, modify, implement and improve procedures for source identification and proper response when contamination is known.

2.5.2

Maintenance and Operations Activities

The City of Sumner’s Maintenance and Operations Crew provides various services to inspect, maintain, repair and install stormwater structures and facilities. Agreements, Stormwater Pollution Prevention Plans and Maintenance Standards, were developed to aid with the maintenance and operation of these systems.

21 of 27

City of Sumner SWMP 2013

The City’s maintenance standards for stormwater facilities are addressed in the Agreement to Maintain Stormwater Facilities and to Implement a Pollution Source Control Plan as shown in Appendix C or in a SWPPP specific to the site. The agreement standards are composed of those specified in Chapter 4 of Volume V of Ecology’s 2005 SWMMWW and addresses various types of BMP’s, identifiable water quality issues, as well as proper maintenance of each BMP. Catch basins are currently inspected with routine maintenance activities. These smaller activities are done on an as-needed basis. However, a complete cleaning of the MS4 system is typically performed bi-annually to ensure good housekeeping behaviors are followed. Ongoing street sweeping activities help minimize the need for catch basin cleaning. Stormwater Pollution Prevention Plans (SWPPP’s) were developed for City facilities likely to discharge to the City stormwater infrastructure. These facilities include: the Sumner Wastewater Treatment Facility (WWTF), Sumner Meadows Golf Links, and Street Maintenance Division. Each SWPPP describes implemented measures to reduce stormwater impacts including pollutant discharges from all the areas owned by the City. They also include on-going training programs for employees. The SWPPP's for each City facility contain recommendations for routine pollution prevention, stormwater facility maintenance, stormwater facility inspection schedules, and training related to stormwater pollution prevention. SWPPP’s for City facilities are contained in separate documents entitled City of Sumner Wastewater Treatment Facility Stormwater Pollution Prevention Plan, City of Sumner Sumner Meadows Golf Links Stormwater Pollution Prevention Plan, and City of Sumner Street Maintenance Stormwater Pollution Prevention Plan. An Agreement to Maintain Stormwater Facilities and to Implement a Pollution Source Control Plan was previously executed for the City Shop. To satisfy the requirements of this component of the Permit for City owned facilities, the City has developed and implemented a plan to inspect of all the inlets, ponds, oil water separators and grease interceptors stormwater treatment and flow control facilities owned and operated by the City. Our Maintenance and Operations crew annually inspects all City owned stormwater facilities, verifying proper function and managing maintenance when necessary. The plan also includes spot checks on potentially damaged permanent treatment and flow control facilities after major storm events. Catch basins are typically cleaned bi-annually due to the efficiency of our scheduled sweeping of the City roadways. The plan also includes documentation of the inspections and work performed or needed on the stormwater facilities.

22 of 27

City of Sumner SWMP 2013 2.5.3

Future Maintenance and Operations Activities

The City will continue to inspect and maintain facilities as described by the SWPPPâ&#x20AC;&#x2122;s, Maintenance Agreements and in accordance with NPDES Permit regulations established for City owned equipment and structures. Maintenance checklists will be documented and recorded to reflect the current maintenance and operating status of the facility. Spot checks and annual inspections of the Cityâ&#x20AC;&#x2122;s MS4 will continue as scheduled. Maintenance will be performed to resolve any identified issues or water quality concerns. The City will continue to identify and develop methods for reducing stormwater pollution from roadways, parking lots and other City owned facilities in accordance with the NPDES Permit standards. Training seminars will be scheduled to maintain the status of currently certified employees as well as certify other staff as this program continues to develop. The Maintenance and Operations program for preventing pollution generated from City owned facilities will continue to modify its current processes and maintenance programs in an effort to develop efficient practices and methods for pollution reduction. In order to accomplish this objective, the City will utilize training opportunities and informational seminars to learn and educate staff of the potential means and methods of maintenance and operations applicable to City owned facilities.

2.6

MONITORING

The Clean Water Act requires municipalities to obtain an NPDES Permit and to develop a stormwater management programs to prevent harmful pollutants from reaching local water bodies. The first NPDES Phase II Permit cycle (2007-2012) did not require any water quality monitoring for the City, unless it was pursuant to a TMDL requirement or part of the IDDE program. Due to the size of Sumner (population under 10,000), the City was not required to develop a monitoring program. This requirement however, will be changing with the administration of the next cycle of permits. Ecology recently issued the next cycle of Phase II Permits including the implementation of a regional monitoring program to include 3 monitoring programs. The first program is called Status and Trends monitoring. This program focuses to monitor the status of the marine near shores and streams of Puget Sound, by sampling and examining muscle growth and habitat, sediment and benthos in the local streams and shorelines. The second proposed program involves Regional Effectiveness Studies. The specific studies to be conducted are yet to be determined. In the 2010 annual report, Permittees were required to submit two questions with selected sites where a monitoring study could be implemented. These questions were gathered and will be used as a starting point for Ecology to determine the studies to be conducted during this next Permit cycle. The third program to implement is a Source Identification Program which proposes to develop an Illicit Discharge Detection and Elimination Manual for Western Washington. This Manual would include: a Quality Assurance Program Plan (QAPP) Library, information repository and Standard Operating Procedures (SOPs) for identification and diagnostic monitoring. A data base will also be developed for regional use and provide assistance in identifying locations in need of additional education efforts. These programs will be funded through an allocation process for which participating agencies will be charged an annual cost or fee for the implementation of each program. The estimated annual cost for the City of Sumner to participate in all three programs is approximately $6,254.00. If the City chooses to opt out of an individual program or two programs, the costs to remain compliant with Permit requirements may increase significantly with the additional funding necessary to purchase equipment, lab testing and staffing resources. The City has until December 1st of 2013 to determine and notify Ecology regarding the Cityâ&#x20AC;&#x2122;s participation in the regional monitoring program. Although the City is not currently required to implement a monitoring program, the City established a Groundwater and Stream Low Flow Monitoring program to provide useful data regarding groundwater gradients, calibrate a hydrologic and hydrogeological model, and evaluate the feasibility of utilizing infiltration techniques such as Low Impact Development (LID) technologies.

City of Sumner SWMP 2013

The Groundwater and Stream Flow Monitoring program consists of 12 shallow groundwater monitoring wells and 4 stream gauges. The groundwater monitoring wells measure the depth of the groundwater and record the data using data loggers. The stream gauges located in Salmon Creek, Middle Creek and Milwaukee Ditch (2) measure depth and velocity of the flow and record using data loggers as well. The goal of this monitoring is to estimate groundwater gradients within the White River Valley to assess whether development has an effect on groundwater flow patterns and stream base flows. The City has also implemented a second monitoring program. This monitoring program has been established to track stormwater runoff from a small Low Impact Development in Sumner. The equipment purchased in 2007 includes a rain gauge, soil saturation meter, weir and other related telemetry and controls. The runoff/weather station was installed in 2008 and has then been programmed to record data regarding the amount of rainfall, and soil moisture to try and determine the infiltration rate and efficiency of the implemented LID system. Data from this station has been collected and is in the process of being converted and formatted to better understand the results of LID implementation. Another monitoring project the City recently initiated is the water quality testing of Salmon Creek. The Department of Ecology in June of 2011 issued a Total Maximum Daily Load (TMDL) for Fecal Coliform in the Puyallup River Watershed. This report identified Salmon Creek as a tributary in need of fecal coliform reduction in order to meet state water quality standards. In response to this report, the City of Sumner began to study and sample various locations on the Creek to identify potential causes and sources of Fecal contamination in the stream. The City and Tacoma Pierce County Health Department are currently in the process of investigating possible sources of fecal contamination in relation to Salmon Creek. Samples of the creek and testing of the water will continue until fecal rates are below the water quality standards identified in the TMDL report. Although the City of Sumner is not required to submit an established plan and site locations for future long term monitoring, the City was required to develop a plan for two effectiveness monitoring experiments. This plan identifies two hypotheses to be tested, sites for which the data will be retrieved and an explanation of why these suggested plans would be of significance use to other jurisdictions. This document is included as a part of the annual Permit that was submitted to Ecology for the year 2010. As this first Permit cycle has come to an end the City will continue to improve its program components to remain in compliance with Permit standards and regulations. A final draft of the next cycles of NPDES Phase II Permits was issued September of 2012 with the 1-year reissuance of the current Permit to be followed by the issuance of the next 5-year Permit.

City of Sumner SWMP 2013

CONCLUSION

The City of Sumner has met all the minimum requirements for the first cycle of NPDES requirements. The City has an established stormwater utility that is and will continue to be a funding source for stormwater facility improvements and permit requirements. There are many projects and activities that the City is performing and executing that line up with Permit requirements. In the coming years there will be several more programs and activities to develop and implement to remain in compliance with the issuance of new Phase II NPDES Permits. The Public Education and Outreach component for the SWMP continues to provide materials and opportunities for the public to learn and participate in stormwater related activities. During the next reporting period the City will need to develop and distribute more educational materials to specific target audiences listed in the new Permit. The City also needs to continue documenting the progress of the behaviors of the targeted audiences and compare the results with those from past administered surveys. The City is actively participating in several watershed groups as part of their Public Involvement and Participation component. This relationship will continue and promote involvement of local residents in the development of this SWMP document. The City also needs to continue to create programs and events such as a stencil or emboss “Dump No Waste – Drains to Stream” project near all stormwater inlets, or a restoration project on Salmon Creek to keep local citizens involved and aware of the impacts they can have on the environment. The City has developed a stable Illicit Discharge Detection and Elimination program. The MS4 maps include the City’s existing infrastructure and will continue to develop as more information and as- builts are gathered. The SMC’s clearly state the procedures for managing and resolving illicit connections and discharges. Documentation of the inspections, spills, feedback and training is currently in place to meet the Permit requirements. The City of Sumner Development Specifications and Standard Details and SMC’s reflect the requirements for Controlling Runoff from New Development, Redevelopment and Construction Sites. These modifications will bring the City standards into alignment with many future requirements of the Permit. Additional work will be necessary to maintain documentation of inspection and enforcement actions and continue training for City staff according to the Permit requirements. The Maintenance and Operations component of the SWMP has a solid agreement in place for maintaining stormwater facilities and pollution source control plans. The SWPPP’s created for Street Maintenance; Sumner Meadows Golf Links and the Wastewater Treatment Facility have established guidelines and requirements for reducing and preventing pollution during operation and maintenance of Municipal facilities. The City shops operate under an Agreement to Maintain Stormwater Facilities and to Implement a Pollution Source Control Plan.

SUMNER Approximately 75% of all pollution in Puget Sound comes from stormwater runoff that starts in our neighborhoods.

Look for the sign!

Clean& Green

When you support a fundraiser car wash in Sumner, look for the city’s Clean & Green symbol. This way, you know this wash is using the city’s Car Wash Kit to raise money without making our rivers and environment pay the price.

Whether you enjoy fishing, hiking, boating or simply drinking clean water, this affects you. Every time you wash your car on a driveway that drains onto a street, you’re pouring your car’s grease, grime plus some soap, into our rivers and water system!

How to Wash Your Car (& Not Get the River Dirty)

Find out more

www.ci.sumner.wa.us www.PugetSoundStartsHere.org http://www.ecy.wa.gov/pubs/95056.pdf

A few changes to your routine will keep grease and soap out of our rivers and fish.

Washing Your Vehicle What can you do to wash your car without dirtying the environment?

Charity Car Washes The Problem

What about charity car washes? How can they operate in parking lots within the law?

1. Go to a commercial car wash. By law, they must run the water through special filters and processes so that it is not sending the soap and grease into the storm drains and rivers

1. Hold car wash on gravel. Same principle applies with the ground filtering the grease and soap out of the water before it returns to our water system.

2. Wash vehicles on lawn or gravel. The soil is a natural filter. By washing your car on the lawn or gravel, your run-off will be filtered by the ground rather than go into the street to the storm drain and to the river.

2. Check out the Car Wash Kit. Sumner has a car wash kit that diverts water from the storm drain and into the sewer system where it will get treated before returning to the river. One kit is available on a first-come, first-serve basis, so act early. Contact the Permit Center at 253-299-5530.

3. Divert the water. Many of Sumner’s driveways are adjacent to gravel alleys rather than the street. If you are sure your run-off water is going into a gravel alley or lawn, you’re fine. 4. Use biodegradable soaps. Biodegradable soaps are known to be less harmful to the environment, but still contain oxygen depleting chemicals. Use sparingly and in addition to rather than instead of the other options. 5. Use a California Duster Wax coated cotton strands lift dust without scratching paint. When used often enough, the duster can reduce number of car washings.

Storm drains go right into the river without passing through the wastewater treatment plant. If you wash your car in your driveway or on pavement that leads to the street, you’re sending the grease and oil and even detergent right into the Puyallup and White rivers. What else can you do? • Pick up pet waste. If left in the yard, it also gets washed down the storm drains by rain. • Don’t overfertilize. Extra fertilizer doesn’t go into the ground--it waits on top for the next rain to wash it down the drain and into the river.

3. Reward Clean & Green washes. Car washes using the Car Wash Kit will have a sign that says “Clean & Green.” If a charity car wash isn’t on gravel and doesn’t have the sign, pass it by. If you feel comfortable, let them know that you would have been happy to support their cause if they were taking the proper precautions to keep our water clean.

TAKE OUTDATED MEDICATIONS TO CITY HALL Puget Sound starts here in Sumner.

When to fertilize

Winter

Spring

Summer

Fall

A little knowledge and planning means a lot less useless fertilizer going into our water system.

www.ci.sumner.wa.us vegetables

Although spring is the absolute best, you can also add amendments (compost or manure) in winter as well and till into the soil.

Fertilize when soil is being tilled and prepared for planting. Use a ratio of 1 nitrogen-2 phosphorus-2 potassium and apply 20 lbs per 1,000 sq ft. Till into top 6-8 inches of soil.

grass

Fertilize November 15-December 7 Use a ratio of 3 nitrogen-1 phosphorus-2 potassium (21-7-14 or 15-5-10) Never use more than 4 lbs of nitrogen per 1,000 sq ft per year.

Fertilize April 15-May 7. Use a ratio of 3 nitrogen-1 phosphorus-2 potassium (21-7-14 or 15-5-10) Never use more than 4 lbs of nitrogen per 1,000 sq ft per year.

perennials

Fertilize June 15-30. Use a ratio of 3 nitrogen-1 phosphorus-2 potassium (21-7-14 or 15-5-10) Never use more than 4 lbs of nitrogen per 1,000 sq ft per year.

Fertilize September 1-15. Use a ratio of 3 nitrogen-1 phosphorus-2 potassium (21-7-14 or 15-5-10) Never use more than 4 lbs of nitrogen per 1,000 sq ft per year.

Summer and fall flowers: use seven tablespoons of 10-10-10 soluble fertilizer or equivalent monthly from shoot emergence until the plants reach full flower.

Spring flowers: when planting bulbs use five tablespoons of 10-10-10 soluble fertilizer or equivalent.

Apply a ratio of 1 nitrogen-2 phosphorus-2 potassium just before plants begin a new season of growth. Apply 20 lbs per 1,000 sq ft over the root zone. Use shallow cultivation or irrigation.

bulbs

Spring flowers: use five tablespoons of 10-10-10 soluble fertilizer or equivalent when shoots begin to show. Do NOT fertilize after flowering.

shrubs

Use nitrogen-rich fertilizer (i.e. 16-8-8, 21-7-14 or 20-10-5) February through May. Fertilize according to the shrub’s height or spread. Use .05 to .10 pounds of nitrogen per foot of shrub.

deciduous trees

Use 2 lbs of nitrogen per 1000 sq ft in when leaves start showing, February through May.

annuals

Although spring is the absolute best, you can also add amendments (compost or manure) in fall as well and till into the soil.

Fertilize 1-2 times during growing season. Use higher nitrogen until plants reach full size, then switch to high in phosphorus for increased blooming.

Utility Billing Stormwater Facts:

•

Think about washing your car at a carwash. Washing your car in the driveway or street allows the chemical soaps, gunk and grime to wash into the drains and out into our rivers and streams. If you are going to wash at home, wash on the lawn or gravel. 11-28-12

•

Be mindful when fertilizing. Know the proper amounts and time of year to fertilize your plants. Check out our website for a poster with more information! http://www.ci.sumner.wa.us/Documents/Public%20Works/Fertilizer_poster.pdf 2-26-13

•

Did you know most stormwater is not treated and flows directly into our rivers, lakes and streams? Do your part and make sure “only rain goes down the storm drains!” – 7/26/12

•

See something other than rain water running into the storm drain? Call or email our Report a Problem hotline, at 253-299-5740 or by email at http://www.ci.sumner.wa.us/report_problem.htm.

•

Getting your carpet cleaned by a mobile carpet cleaning company? Make sure the mobile washer doesn’t dump the waste water into the gutter line or storm drain. Waste water should be discharged to sanitary sewer. – 1/22/13

•

Does your car leave a black oil stain on your driveway or street? That oil residue gets washed in to the storm drains when it rains. Help protect our rivers, lakes and streams by fixing your oil leak. Check out the Don’t Drip and Drive website at www.fixcarleaks.org where you can find an ASA shop that will conduct a free oil leak inspection of your vehicle. 3-21-13

Dams resulting in a change or function of the facility When insects such as wasps and hornets interfere with maintenance activities, or when mosquitoes become a nuisance. Tree growth does not allow maintenance access or interfere with maintenance activity (i.e., slope mowing, silt removal, or equipment movements). If trees are not interfering with access, leave trees alone.

Rodent holes

Vegetation not growing or is overgrown.

For grassy ponds, selectively thatch, aerate and reseed ponds. Grass cutting unnecessary unless dictated by aesthetics. For wetland ponds, hand-plant nursery-grown wetland plants in bare areas. Pond bottoms should have uniform dense coverage of desired plant species. Rodents destroyed and dam or berm repaired.

EXHIBIT 2 POLLUTION SOURCE CONTROL PROGRAM WHAT ARE POLLUTION SOURCE CONTROLS, AND WHY ARE THEY NEEDED? Pollution source controls are actions taken by a person or business to reduce the amount of pollution reaching surface and ground waters. Controls, also called "best management practices" (BMPs), include: •

Altering the activity (e.g., substitute non-toxic products, recycle used oil, reroute floor drains to sanitary sewer from storm sewer).

•

Enclosing or covering the activity (e.g., building a roof)

•

Segregating the activity (e.g., diverting runoff away from an area that is contaminated)

•

Routing runoff from the activity to a treatment alternative (e.g., to a wastewater treatment facility, sanitary sewer, or stormwater treatment area).

Pollution source controls are needed because of the contamination found in runoff from commercial areas and the effect of this contamination on aquatic life and human health. Research on urban runoff in the Puget Sound area and elsewhere has found oil and grease, nutrients, organic substances, toxic metals, bacteria, viruses, and sediments at unacceptable levels. Effects of contaminated runoff include closure of shellfish harvesting areas and swimming areas, mortality of young fish and other aquatic organisms, tumors on fish, and impairment of fish reproduction. PROFESSIONAL SERVICES DESCRIPTION: Presented here are the remaining service businesses including theaters; hotels/motels; finance, banking, hospitals and medical services; nursing homes, schools and universities, and legal, financial and engineering services. MATERIALS USED AND WASTES GENERATED: The primary concern is runoff from parking areas. Stormwater from parking lots will contain undesirable concentrations of oil and grease, suspended particulates, and metals such as lead, cadmium, and zinc. It will also contain the organic byproducts of engine combustion. Some also produce Dangerous Wastes, for example, hospitals, nursing homes, and other medical services. These materials are stored within the building until disposal. REQUIRED ACTIONS: The following actions shall be taken to ensure that pollution generated on site shall be minimized: R:\Development\SWMA- Stormwater Maintenance Agreements\SWMA Base\Stormwater Maintenance Ageement-corporation 7-10.doc Page 21 of 22

Warning signs (e.g., "Dump No Waste--Drains to Stream") shall be painted or embossed on or adjacent to all storm drain inlets. They shall be repainted as needed.

Parking lots shall be swept when necessary to remove debris and, at a minimum, twice a year. Use of newer model high-velocity vacuum sweepers is recommended as they are more effective in removing the more harmful smaller particles from paved surfaces.

Sediment removed from ponds/catch basins shall be disposed of in a proper manner. Contact the City for instruction prior to completing this task.

No activities shall be conducted on site that is likely to result in short-term highconcentration discharge of pollution to the stormwater system. Such activities may include, but are not limited to; vehicle washing, vehicle maintenance, and cleaning of equipment used in the periodic maintenance of buildings and paved surfaces.

Employees shall receive basic instruction regarding the control of pollution from commercial operations. Contact the Public Works Department at (253) 863-8300.

Medical offices with high volume customer contacts have potential to influence individuals' water quality practices. Owners are encouraged to have informational brochures provided by the City (see Item 5 above) available in waiting rooms.
