Rick McBroom, Water Resources Engineer, briefed the Committee on the 2009 Annual Report for the National Pollutant Discharge Elimination System (NPDES) Phase II Municipal Stormwater Permit. The permit, issued by the Department of Ecology in 2007, requires the City to create and implement a Stormwater Management Program (SWMP) which addresses five program elements: 1) Public Education and Outreach, 2) Public Involvement and Participation, 3) Illicit Discharge Detection and Elimination, 4) Controlling Runoff from Development and Construction Sites, and 5) Pollution Prevention, and Operations and Maintenance for Municipal Operations. The permit authorizes the City’s discharge of stormwater to surface waters and groundwaters of the state, and requires an Annual Report to be in compliance. The report must be submitted to DOE by March 31, 2010.
Rick listed key requirements for 2009 that need to be updated in the Stormwater Management Program and Annual Report:
- An ordinance prohibiting non-stormwater, illegal discharges, and dumping into the City’s storm sewer system. Council adopted Ordinance No. 1332 updating the City’s stormwater maintenance standards.
- Education and Outreach/Public Involvement programs to change behaviors and practices that contribute to adverse stormwater impacts. The City continues ongoing public outreach programs through Stream Team, community events, workshops, neighborhood meetings and site visits.
- Track estimated cost of development and implementation of each component of the SWMP. The City is tracking the number of inspections, official enforcement actions and public education activities through specialized software programs.
- Develop and implement a program to detect and address non-stormwater discharges, spills, illicit connections and illegal dumping into the City’s storm sewer system. The City has begun development of the Illicit Discharge Detection and Elimination Program (IDDE) to address these issues. Rick said staff will identify what pollutants come through the basin, and then track them back to the source by monitoring upstream sites.
- Implement requirements to control quality and quantity of stormwater runoff at new development, redevelopment and construction sites. Council adopted Ordinance No. 1342 to create the 2010 Stormwater Design Manual.
Staff responded to Council questions on several issues:
- There is a lack of federal funding sources for implementation of the SWMP. Limited grant funding was provided by the EPA through DOE which was dispersed to competing local jurisdictions. Councilmember Mary Dean noted that with limited funding, the EPA should provide general direction, but should not require specific criteria. Rick remarked although funding is a challenge, progress is being made.
- Stormwater runoff flows to 3 separate basins, which include Woodland Creek, Woodard Creek and the Deschutes River.
- Stormwater runoff is filtered through a storm pond system; a treatment/ settling pond and then an infiltration pond prior to discharging to groundwater. Peter Brooks Water Resources Manager, remarked it is important to prevent contaminants from entering the storm system, such as soap, and oil.
- The City coordinates with the County on development and implementation of its SWMP, and participates regionally through the Technical Advisory Group, Stream Team, and the Stormwater Outreach Board. Rick noted the City of Lacey successfully partnered with the City of Olympia on the Fones Road Treatment Facility to control storwmater runoff from Sleater Kinney Road.
- Funds have been approved for a Car Wash Program that would provide community (fund raising) car washes with 2 catch basin inserts to reduce the runoff of soapy water. Rick noted that car wash owners are responsible for cleaning the catch basins at their facilities annually. The City will begin initiating a program to notify property owners they must report to the City on the management of their storm systems.
- Neighborhood Homeowner Associations are responsible for storm pond maintenance. If no HOA exists, and the City performs the service, a maintenance fee will be charged to the residents.
Rick reported 2010 requirements and activities will include continuing education, continuing development of the IDDE Program, verifying municipal storm sewer system maps, continuing regional coordination, developing and implementing an Operations and Maintenance Program (O & M), and developing a tracking system for inspections and enforcement. Rick noted the most expensive component for the City will be the O & M program, because storm systems will need to be maintained and modified. Septic to Sewer Conversion
In other business, the Committee discussed failing septic systems in the City. Currently, residents are responsible for the maintenance of their septic systems. Scott Egger, Public Works Director, reported surveys were conducted in the Enterprise/Midway neighborhood and the Homann/Alanna neighborhood in the fall of 2008 to determine if residents would be interested in forming a ULID (Utilities Local Improvement District) to convert from septic to City sewer. The responses were not favorable, because costs were estimated at $35,000 per lot. Scott noted the Department of Ecology has limited funds available for repairing failing sewer systems and that septic conversion projects have never competed well for those funds.
Scott added that Woodland Creek Estates is a regional priority project for septic to sewer conversion, due to its negative impact of the septic systems on the water quality in Woodland Creek and Henderson Inlet.
