University of Washington (UW) Bothell and Cascadia College (CC) are classified as a Secondary Permittee under the Western Washington Phase II Municipal Stormwater Permit (Permit). As such, UW Bothell and CC must comply with Permit requirements, and all relevant ordinances, rules and regulations of the local jurisdiction (City of Bothell). Applicable rules and regulations include the City of Bothell stormwater and drainage control code, Chapter 18.04 and City of Bothell Surface Water Management Program.
As a Phase II Secondary Permittee, UW Bothell and CC are required to develop and implement a Stormwater Management Program (SWMP). This document serves as the UW Bothell and CC SWMP. The UW Bothell and CC SWMP is designed and implemented to reduce the discharge of pollutants from the stormwater system to the maximum extent practicable and protect water quality.
This UW Bothell and CC SWMP includes the following six (6) minimum measures:
- Public education and outreach on the impacts of stormwater pollution,
- Public involvement and participation,
- Illicit discharge detection and elimination,
- Construction site stormwater runoff control,
- Post-construction stormwater management for new development and redevelopment, and
- Pollution prevention and good housekeeping for facilities operations.
The SWMP describes these six minimum measures. Following each measure description is a list of actions that UW Bothell and CC are conducting to meet these requirements. The dates for completing these actions is available on the City of Bothell Stormwater Maintenance and Inspections Website.
According to the Permit, UW Bothell and CC will implement the following stormwater education strategies:
- Storm drain inlets owned or operated by UW Bothell and CC that are located in maintenance yards, in parking lots, along sidewalks, and at pedestrian access points will be clearly labeled with the message similar to “Dump no waste – Drains to water body.” As identified during visual inspection and regular maintenance of storm drain inlets per the requirements of S6.D.3.d. and S6.D.6.a.i. below, or as otherwise reported to UW Bothell and CC, any inlet having a label that is no longer clearly visible and/or easily readable will be re-labeled within 90 days.
- Each year, beginning no later than three years from the initial date of permit coverage, public ports, colleges, and universities will distribute educational information to tenants and residents on the impact of stormwater discharges on receiving waters, and steps that can be taken to reduce pollutants in stormwater runoff. Distribution may be by hard copy or electronic means.
Appropriate topics may include:
- How stormwater runoff affects local water bodies,
- Proper use and application of pesticides and fertilizers,
- Benefits of using well-adapted vegetation,
- Alternative equipment washing practices, including cars and trucks that minimize pollutants in stormwater,
- Benefits of proper vehicle maintenance and alternative transportation choices; proper handling and disposal of vehicle wastes, including the location of hazardous waste collection facilities in the area, and
- Hazards associated with illicit connections, and illicit discharges.
- Benefits of litter control and proper disposal of pet waste.
To meet this requirement:
- Most storm drains at UW Bothell and CC have gratings forged with “Outfall to Stream / Dump No Pollutants” on them. The gratings that do not have this forged on them are labeled with plastic pucks that say “No dumping, drains to wetlands.” UW Bothell Facilities Services has a stormwater system and catch basin preventative maintenance program.
- The stormwater system is cleaned and inspected annually.
- The UW Bothell Sustainability Office has a stormwater awareness brochure for students and staff.
According to the Phase II permit, UW Bothell and CC will:
- Make the annual report available on the UW Bothell and CC website.
- Make available on the UW Bothell and CC website the latest updated version of the SWMP Plan.
- If UW Bothell and CC does not maintain a website may submit their updated SWMP Plan in electronic format to Ecology for posting on Ecology’s website.
According to the Phase II permit, UW Bothell and CC will:
- From the initial date of permit coverage, comply with all relevant ordinances, rules, and regulations of the local jurisdiction (City of Bothell) in which UW Bothell and CC are located that govern non-stormwater discharges.
- Implement appropriate policies prohibiting illicit discharges and an enforcement plan to ensure compliance with illicit discharge policies.
These policies will address, at a minimum: illicit connections; non-stormwater discharges, including spills of hazardous materials; and improper disposal of pet waste and litter.
- Allowable discharges: The policies do not need to prohibit the following categories of non-stormwater discharges:
- Diverted stream flows
- Rising ground waters
- Uncontaminated ground water infiltration (as defined at 40 CFR 35.2005(20))
- Uncontaminated pumped ground water
- Foundation drains
- Air conditioning condensation
- Irrigation water from agricultural sources that is commingled with urban stormwater
- Uncontaminated water from crawl space pumps
- Footing drains
- Flows from riparian habitats and wetlands
- Discharges from emergency firefighting activities in accordance with S2 Authorized Discharges
- Non-stormwater discharges authorized by another NPDES or State Waste Discharge permit
- Conditionally allowable discharges: The policies may allow the following categories of non-stormwater discharges only if the stated conditions are met and such discharges are allowed by local codes:
- Discharges from potable water sources, including but not limited to water line flushing, hyper-chlorinated water line flushing, fire hydrant system flushing, and pipeline hydrostatic test water. Planned discharges will be de-chlorinated to a total residual chlorine concentration of 0.1 ppm or less, pH-adjusted if necessary, and volumetrically and velocity controlled to prevent re-suspension of sediments in the MS4.
- Discharges from lawn watering and other irrigation runoff. These discharges will be minimized through, at a minimum, public education activities and water conservation efforts conducted by UW Bothell and CC and/or the local jurisdiction (City of Bothell).
- De-chlorinated swimming pool, spa, and hot tub discharges. The discharges will be de-chlorinated to a total residual chlorine concentration of 0.1 ppm or less, pH-adjusted and re-oxygenated if necessary, and volumetrically and velocity controlled to prevent re-suspension of sediments in the MS4. Discharges will be thermally controlled to prevent an increase in temperature of the receiving water. Swimming pool cleaning wastewater and filter backwash will not be discharged to the MS4
- Street and sidewalk wash water, water used to control dust, and routine external building washdown that does not use detergents. UW Bothell and CC will reduce these discharges through, at a minimum, public education activities and/or water conservation efforts conducted by UW Bothell and CC and/or the local jurisdiction (City of Bothell). To avoid washing pollutants into the MS4, the Secondary Permittee will minimize the amount of street wash and dust control water used.
- Other non-stormwater discharges will be in compliance with the requirements of a pollution prevention plan reviewed by the Permittee which addresses control of such discharges.
- UW Bothell and CC will address any category of discharges in bullets two and three above if the discharge is identified as a significant source of pollutants.
- Maintain a storm sewer system map showing the locations of all known storm drain outfalls, labeling the receiving waters (other than groundwater), and delineating the areas contributing runoff to each outfall. Make the map (or completed portions of the map) available on request to Ecology and to the extent appropriate to other Permittees. The preferred format for mapping is an electronic format with fully described mapping standards. An example description is provided on Ecology’s website.
- Conduct field inspections and visually inspect for illicit discharges at all known MS4 outfalls. Visually inspect at least one third (on average) of all known outfalls each year beginning no later than two years from the initial date of permit coverage. Implement procedures to identify and remove illicit discharges. Keep records of inspections and follow-up activities.
- Implement a spill response plan that includes coordination with a qualified spill responder.
- No later than two years from initial date of permit coverage, provide staff training or coordinate with existing training efforts to educate staff on proper BMPs for preventing illicit discharges, including spills. Train all UW Bothell and CC staff who, as part of their normal job responsibilities, have a role in preventing such illicit discharges.
To meet these requirements:
- UW Bothell and CC has a policy to meet or exceed all environmental laws.
- UW has developed and adopted policies that prohibit illicit discharges and illegal dumping.
- UW Bothell and CC has a storm system map showing all known storm drain outfalls, receiving waters and storm drainage areas.
- UW Bothell and CC inspect stormwater outfall annually.
