Resources and guidance for local stormwater managers implementing permit requirements for operation and maintenance of municipal storm sewer systems.
The following materials were prepared by Washington state municipal stormwater permittees to support their permit implementation. The permittees have made these materials available to others to modify for their own use. Ecology has not formally reviewed and approved these materials.
Stormwater Best Management Practices – training PowerPoint by Ellen Stewart, Seattle Public Utilities
Storm Watch - the City of Bremerton's fact sheet for municipal employees on BMPs to prevent pollution and identify illicit discharges
Seattle developed a generic SWPPP for all heavy equipment maintenance or storage yards and material storage facilities conducted at facilities owned or operated by their Fleets and Facilities Department. This SWPPP is based on Ecology's existing SWPPP guidance for industrial facilities, but has been modified to remove those components that are relevant only to industrially-permitted sites.
An Ecology industrial stormwater SWPPP template differs in some ways from a SWPPP under the municipal permit but may be a good starting point for developing a SWPPP that meets the municipal stormwater permit requirements. Permittees should consult the appropriate municipal permit section and modify the template as needed. For example, water quality sampling under Section 4 - Sampling Plan of the template does not apply. Other references to the Industrial permit, BMP implementation schedules, inspections, and reporting throughout the template should also be modified to comply with SWPPP requirements under the municipal permit.
The City of Kent prepared the following Stormwater Pollution Prevention Plan (SWPPP) for its heavy equipment maintenance/storage yard and materials storage facility. Appendix B provides a list of the associated Best Management Practices (excerpted from Volume IV of the Ecology 2005 Stormwater Management Manual for Western Washington). Please contact Shawn Gilbertson, Kent NPDES Coordinator, for more information, email@example.com.
Mercer Island developed the following SWPPPs to cover its Administrative and Maintenance Site and two major parks. Both SWPPPs include several forms (e.g., Spill/Leak Records, Inspection sheets (dry and wet weather), and training records) that may be of interest to permittees.
Ecology prepared this spill kit checklist to support the work of the Local Source Control Program, which supports local government efforts in Puget Sound and Spokane with on-site technical assistance to businesses. This kit checklist will help create a kit that could be used to mop up small oil and grease spills. Other types of kits are designed for specific spill types – other chemicals, other viscosities, etc.
Pierce County's Stormwater Maintenance Manual for Private Facilities provides descriptions and maintenance checklists for 32 common stormwater facilities/components. These checklists are consistent with the maintenance standards specified in Chapter 4 of Volume V of the 2005 Stormwater Management Manual for Western Washington. It also provides guidance on vegetation management and information for private facility owners on developing a maintenance program and working with contractors.
The City of Wenatchee developed an Operations and Maintenance Plan template and Template Guidance. The O&M Plan Template is designed so that municipalities can quickly develop an O&M Plan that meets the Eastern Washington Phase II Permit requirements. The resulting O&M Plan for each community will focus on the activities and BMPs that field staff, supervisors, and managers need to implement on a regular basis in order to meet the Eastern Washington Phase II Permit requirements. The O&M Plan can also be utilized as a training document to instruct field staff on the activities and BMPs that must be implemented in order to meet the water quality requirements of the Eastern Washington Phase II Permit. The major participating partners included the city of East Wenatchee, Douglas and Chelan Counties. Other jurisdictions throughout Eastern Washington were also involved in the development of the template. Funded by an Ecology Grant of Regional or Statewide Significance.
The Port of Seattle shows and discusses their new tool and procedure for cleaning docks over water in this short video.
Seattle's Department of Transportation Best Management Practices (BMP) Manuals cover many types of transportation maintenance activities, from concrete repair to tree management. If you would like to use any of this material, including text and photos, please contact Maureen Meehan at the City of Seattle, (206) 684-8750 or Maureen.Meehan@Seattle.gov for a format that can be edited.
Ecology welcomes and encourages permittees to send us additional examples. Please work with your regional permit manager to add your SWMP program materials to this webpage.
