Chapter 16.55
BEST MANAGEMENT PRACTICES
Sections:
16.55.010 Stormwater Pollution Prevention Manual.
16.55.010 Stormwater Pollution Prevention Manual.
(1) General. The King County Stormwater Pollution Prevention Manual (BMP manual) applies to existing facilities and activities and to new development activities not covered by the King County Surface Water Design Manual (KCSWDM) and Federal Way Addendum to the KCSWDM. The BMP manual describes the types of regulated activities, the types of contaminants generated by each activity, the contaminant’s effect on water quality, the required source control BMPs, and the available treatment BMPs. The BMP manual includes information on design, maintenance, allowable use of alternative BMPs, and a schedule for BMP implementation.
(2) Priority of BMP implementation. Compliance with this section shall be achieved through the use of best management practices described in the BMP manual. In applying the BMP manual, the director or his/her designee shall first require the implementation of source control BMPs unless the BMP manual specifically requires treatment BMPs. If source control BMPs (or treatment BMPs if required by the BMP manual) do not prevent contaminants from entering surface and stormwater or groundwater, the director or his/her designee may require implementation of additional source control BMPs and/or treatment BMPs according to AKART.
(3) Prevention of pollution of surface and groundwaters. BMPs shall be applied as required herein, so that when all appropriate combinations of individual BMPs are utilized, pollution of surface or groundwaters is prevented. If all BMPs required herein or by the director are applied, and pollution still occurs, the discharger shall modify existing practices or apply further water pollution control measures, as specified by the director. In the absence of implementation of applicable BMPs, the director shall be authorized to conclude that individual activities are causing pollution in violation of this chapter, and shall be authorized to enforce this chapter accordingly.
(4) Technical assistance. The Federal Way surface water management division will provide, upon reasonable request, available technical assistance materials and information, and information on outside financial assistance options, to persons required to comply with this title.

16.55.020 Exemptions.
It is intended that all persons shall apply appropriate BMPs, whether as required by this title or under the authority of another program. Notwithstanding the requirements of FWRC 16.55.010, implementation of BMPs prescribed by this chapter is not required when:
(1) Alternative BMPs are being implemented pursuant to another federal, state, or local program, unless the director determines the alternative BMPs will not prevent or sufficiently reduce the discharge of contaminants. If the other program permitting alternative BMPS requires the development of a best management practices plan, the person shall, upon request and at no cost to the city, provide the director a copy of the BMP plan within five days of the request;
(2) A general or individual NPDES permit for stormwater discharges has been issued by the Washington State Department of Ecology for the property or activity in question, and the NPDES permit includes a water quality pollution control plan; unless the director determines that the plan is not being implemented or that implementation of the water quality pollution control plan will not prevent or sufficiently reduce the discharge of contaminants;
(3) A farm management plan approved by the director is being implemented and maintained according to the plan;
(4) An approved forest practices application has been approved by the Washington State Department of Natural Resources for forest practices, with the exception of forest practices occurring on lands platted after January 1, 1960, or on lands being converted to another use, or regulatory approval has otherwise been issued by the city of Federal Way or other local government under RCW 76.09.240;
(5) The director is authorized to and has issued an exemption from BMP requirements under another provision of this title.
