ISSUE STATEMENT: The City's stormwater/drainage management activities have been evolving since 1999 to address water quality problems and declining conditions of our open waterways. State and Federal requirements, as well as Council objectives, have guided these efforts. Over the past nine years, the City has made significant progress. At the May 5th work session, staff will provide to Council a "State of the Stormwater" presentation, reflecting the CitY's progress to date, current efforts, and future issues and challenges. A IT ACHMENTS: Attachment A - Springfield's "7 Key Outcomes for Stormwater" . Attachment B - Stormwater Management Plan: Six Minimum Control Measures Attachment C - Springfield's TMDL Implementation Plan Summary DISCUSSION: In 1999 and 2000, staff began to inform the Council regarding the conditions of our stormwater drainage system, the effects of urban activities on water quality and drainage capacity, and the steps needed to expand and modify our stormwater management activities. Since that time, Springfield's stormwater management activities have evolved to recognize the functions and benefits the open drainage/stormwater system provides to the community, and to address water quality and drainage problems. This process has been guided by State and Federal Clean Water Act and Endangered Species Act requirements, as well as the Council's "7 Key Outcomes for Stormwater." These Key Outcomes, which were endorsed by the Council in 1999, provided the local framework for the City's first Stormwater Management Plan, 2004. (See Attachment A) Springfield has taken significant steps, and has made substantial progress toward addressing the challenges. Springfield's Stormwater Management Plan was accepted by the Department of Environmental Quality (DEQ), which issued the City a Stormwater Discharge Permit in 2007. The permit and plan enable the City to lawfully discharge stormwater to local rivers and streams, and address the City's obligation to reduce stormwater pollution "to the maximum extent practicable" through implementation of Best Management Practices (BMPs) in six focus areas. (See Attachment B.) Another milestone recently reached by the City was completion and submittal of an Implementation Plan to manage specific pollutants under the Total Maximum Daily Load (TMDL) program requirements of the Clean Water Act. This Implementation Plan, currently under review by the DEQ, will provide a framework for the City's activities to meet mercury, bacteria and temperature reduction goals in our rivers and streams. (See Attachment C.) In November of 2007, staff submitted Springfield's first required annual report to DEQ demonstrating progress under the discharge permit. While the report demonstrates progress, it also reveals that we are somewhat behind in meeting the full range of targets that must be met within the five-year duration of our discharge permit. The City's stormwater management program currently lacks sufficient staff to address all of the permit requirements and to implement required TMDL Implementation Plan activities. These stormwater program deficiencies will be addressed in the fiscal year 2008-2009 budget process. The May 5th presentation will highlight the range of efforts that have been undertaken across the City's various Departments, and how the Council's leadership and guidance have translated into results on the ground. It will briefly touch on forthcoming program requirements, strategies for regulatory compliance, and identified program gaps. This presentation is intended to be both informative and thought-provoking, and to serve as recognition and appreciation of organizations, citizens, businesses, and industries who have stepped up to reduce and minimize stormwater pollution in Springfield. Attachment A Springfield's "7 Key Outcomes for Stormwater" The Springfield City Council adopted the 7 Key Outcomes (Goals) for Stormwater in 1999, as a guide to stormwater management in the City. The Key Outcomes function as guidance for stormwater planning as well as operations and maintenance procedures, and are included as Goals in the City's adopted Stormwater Management Plan. The Stormwater Management Plan. policies provide specific direction, consistent with local goals and State and Federal requirements, and support implementation of the Metro Plan and Public Facilities and Services Plan Policies. The Goals are listed below, along with a summary overview of how each is implemented. Goal 1 - Protect citizens and property from flooding · Maintain surface drainage in the City to reduce the threat of flooding, through proper maintenance of the City's stormwater drainage system infrastructure, with practices that are protective of water quality. GOAL 2 - Ensure compliance with State and Federal requirements to reduce risks of third party lawsuits or enforcement actions. · Implement feasible changes to any applicable City practices and programs to reduce pollutants regulated under the CWA and effectively address applicable provisions of the ESA. Goal 3 - Improve surface and subsurface waters for aquatic life and other beneficial uses · Monitor and implement practices and programs of improving surface and groundwater quality to meet State water quality standards, protect threatened and endangered wildlife, meet State guidelines, and comply with the State Antidegradation Policy. · Maintain open waterways in a manner protective of their natural habitat functions for the benefit of the citizens of Springfield and local wildlife, including threatened or endangered species, and for future generations. Goal 4 - Preserve and maintain surface waters, wetlands, and riparian areas as functional and attractive for people, fish, and wildlife. · Through the development review process, ensure that development is protective of significant open waterways, wetlands, and riparian areas. Implement permitting programs, educational outreach, compliance . Attachment A, page 1 of 2 Attachment A inspections and enforcement activities to reduce erosion, sedimentation, illicit discharges, and other pollution impacts to the City's waterways. Goal 5 - Citizens, businesses, and industries understand the need to protect water quality. .. Develop education, outreach, and technical assistance programs for keeping pollutants out of the stormwater system. Train stakeholders in appropriate erosion control and sediment prevention practices, as well as stormwater management BMPs.. · Seek partnerships with neighborhoods or groups interested in providing stewardship of local waterways (such as Friends of ["xx"] Creek). · Develop appropriate building, design, and Municipal Codes to address water quality issues, including pollution, habitat, and aesthetic issues, to encourage the development of urban waterways that are positive amenities in the community. GOAL 6 - Provide regulatory certainty for the development community while ensuring that growth is not constrained by lack of planning or facilities. · Develop and implement Codes addressing water quality and natural resource management, consistent with State and Federal requirements, to provide clear and objective standards for development. · Develop, within fiscal constraints, adequate stormwater infrastructure, and maintain a Stormwater Facilities Master Plan that identifies public and private infrastructure needed to facilitate planned growth patterns. Goal 7 - Urban drainageways become community amenities · Conduct education and outreach activities to increase understanding of the importance of maintaining safe and clean drainageways, and seek volunteers willing to be caretakers for water features near them. · Through the Development Code and Engineering Design Standards and Procedures Manual, protect open waterways and encourage site planning that enhances the attractiveness and natural functions of the water features. Maintain urban drainageways in a manner that provides for safe and attractive conditions within the limits of fiscal constraints. Attachment A, page 2 of 2 Attachment B City of Springfield's Stormwater Management Plan Six Minimum Measures The Federal Clean Water Act (CWA) National Pollutant Discharge Elimination System (NPDES) program requires cities such as Springfield that own and operate municipal separate storm sewer systems (MS4s) to obtain an NPDES permit for stormwater discharges. One component of this permit is a requirement to develop and implement a Stormwater Management Plan (SWMP). In 2003, Springfield developed its SWMP, which described local receiving waters, the City's stormwater drainage system, and a summary of the City's stormwater management strategies for reducing pollutants discharged from the system. The SWMP was subsequently adopted by the Council in 2004. The Plan addresses six required Minimum Control Measures. For each Minimum Control Measure, the development and implementation of stormwater Best Management Practices (BMPs) are required. In addition, measurable goals for each of the BMPs must be established, responsible parties for implem81ting the BMPs must be identified, and a discussion of the rationale for how and why the specific BMPs are selected must be provided. The 6 Minimum Measures included in the City's SWMP are outlined below: . Citizen Involvement - Involving the public in the process of the SWMP development, as well as subsequent updates, revisions, and amendments of the SWMP and other stormwater-quality related planning efforts. . Public Education and Outreach - Ensuring that stormwater education for businesses, industries, and citizens is a primary emphasis of the plan. . Illicit Discharge Detection and Elimination- Identifying and eliminating sources of dumped, spilled, or illegally discharged pollutants, including inspections, incident tracking, and compliance/enforcement eforts. . Construction Site Erosion Control- Ensuring that erosion at construction sites is minimized through permitting, inspections, and compliance efforts. . Post-Construction Stormwater Management- Ensuring that development provides for long-term stormwater runoff treatment, through effective municipal and development codes and plan review. . Good Housekeeping for Municipal Operations - Reviewing and adapting standard maintenance procedures to ensure that the City's normal maintenance practices, such as eqLipment operation and maintenance, or landscape/waterway management do not contribute pollutants to the stormwater system. Springfield has subsequently developed and submitted an Annual Report to the Oregon DEQ (April 2008); this report is presently underreview by the DEQ, and will allow revisions of the SWMP to enhance and streamline its implementation. Attachment B, page 1 of 1 Attachment C Springfield's Total Maximum Daily Load Implementation Plan Summary The City of Springfield's Implementation Plan (IP, or the "Plan") for the Total Maximum Daily Load (TMDL) program describes strategies the City will implement to reduce temperature, bacteria, and mercury pollution in the Willamette and McKenzie Rivers. The IP is required to comply with the Willamette Basin TMDL order and help meet pollutant load allocations for the Upper Willamette sub-basin as approved by the US Environmental Protection Agency (EPA) in September 2006. The Plan compliments Springfield's existing Stormwater Management Plan, and supports City programs addressing the Clean Water Act, Endangered Species Act, Safe Drinking Water Act, and Springfield's endorsed "Key Outcomes for Stormwater." It describes each of the three major pollutants addressed in theWillamette Basin TMDL (Temperature, Bacteria, and Mercury), their sources in Springfield, and explains the region's water resources and important issues related to water quality. The goal of the Plan is to identify and prioritize measures that the City will take to minimize, to the extent practicable, temperature, bacteria, and mercury contributions to surface waters within the jurisdictional control of the City. It does not propose ordinances, or establish or limit land use, but focuses on education, inspection, municipal operations, and partnerships to reduce specific sources of contamination within the City's jurisdiction, and improve water quality. TMDL Requirements The Clean Water Act of 1977 "authorizes the U.S. Environmental Protection Agency (EPA) to 'restore and maintain the physical, chemical, and biological integrity of all waters of the nation'" (DEQ, 2004). In response to the Clean Water Act, the EPA designated state agencies to develop water quality standards, perform water quality monitoring and/or conduct assessments to understand current conditions, determine sources of pollution, and develop and establish metrics for pollutant loading (the TMDLs) as a tool to improve water quality. Both the McKenzie and Willamette Rivers fail to consistently meet State water quality standards for temperature; the Willamette also fails to meet water quality standards for bacteria, and through a complex analysis, has been listed as not meeting state standards for mercury. The Oregon Administrative Rule that addresses TMDLs requires local governments, agencies to develop TMDL Implementation Plans for listed waterways within their jurisdiction. TMDL Parameters Temperature, bacteria, and mercury are the parameters included in all of the Willamette Basin TMDLs. Brief summaries of these pollutants, as well as their sources and impacts, and potential strategies to address each parameter are included in the Plan. Attachment C, page 1 of 3 Attachment C Strategies in Springfield's TMDL Implementation Plan are summarized below. TEMPERATURE - The Plan proposes to both support and refine existing programs and develop new progra'ms to address gapsinthe City's temperature management. They include: Inventory Existing and Potential Shade & Enhancement Areas · Develop priority project list for shading. · Work to develop public/private partnerships for demonstration projects. · Evaluate tree planting requirements for new development · Review City tree-planting program for streetscape shading opportunities Riparian Protection · Review Development Code and subsequent enhancement for riparian setbacks, buffers, and riparian vegetation management requirements, as appropriate. · Work with Army Corp of Engineers to continue Mill Race Restoration and Temperature Mitigation project. · Continue outreach and education to groups, citizens, businesses, and industry. · Pursue additional or alternative funding sources for shade development projects, as well as project prioritization and phasing to initiate these shading projects. Industrial Discharges · Work with warm water point source dischargers and the DEQ to address point sources through the NPDES permit program. BACTERIA - Springfield's existing water quality programs include Best Management Practices (BMPs) to address bacterial contamination; the strategies below build on or refine existing programs. Sanitary Sewer Overflows - Work Practices · Review current standard operating procedures for spill response. Amend or revise if appropriate to ensure rapid and effective sewer overflow response, cleanup and reporting. · Review contractor work provisions to ensure that contractors know and understand Springfield's requirements for dealing with sanitary spills and are aware of the required cleanup and reporting regulations. Animal/Pet Wastes - Program Enhancement · Coordinate with Willamalane Park arid Recreation District to identify locations for additional pet waste disposal stations in public areas used by pet owners, and work cooperatively to assist with station maintenance and new installations as appropriate. · Inspect pet "parks" and pet day care sites to ensure proper waste handling. · Conduct outreach to recreational wildlife feeders to discourage feeding wildfowl and nutria. Attachment C, page 2 of 3 Attachment C · Continue existing pet waste outreach and education; work with citizen groups, students, and at public events. Septic Tank, Transient Camping and Private Sanitary Infrastructure Outreach and Education · Identify septic systems within the City limits, and assess feasibility or need for connection to the City's sanitary sewer system. · Initiate education and outreach to septic owners where options for hookup to the sanitary sewer system exists. · Continue investigations into illicit recreational vehicle and commercial business waste disposal and sewer cross-connects. · Focus on illegal transient camper enforcement procedures and at sites where wastes impact open waterways. .Seek enforcement through existing camping regulations and local codes. MERCURY - Mercury control efforts focus on supporting and refining existing programs to minimize stormwater runoff and erosion and exploring a post-construction inspection program for stormwater BMPs. Construction Site Erosion Program Review · Review LDAP (construction site erosion control) program, identify program needs, and assist with any program adaptation or support. Post Construction Support · Continue participation in plan review; expand review by water resources staff into broader involvement, particularly of smaller projects. · Initiate development of an ongoing, post-construction BMP inspection program to ensure ongoing maintenance of water quality BMPs at private sites. Street Sweeping Review · Review the existing sweeping program, including equipment, sweeping schedule, and any needed support efforts for equipment upgrades, schedule revisions or service level adjustments, within resource limitations, to optimize program . effectiveness.
