Permit Appealed

On December 29th, 2010, the Puget Soundkeeper Alliance appealed the NPDES permit to the Washington State Pollution Control Hearings Board. The appeal calls for a re-write and reissue as they consider the permit to be ” unlawful and unfair” because it does not meet the “requirements or intent” of the Clean Water Act, Environmental Protection Agency rules, Washington state water quality law ( RCW 98.40 and WAC 173-201A), or Department of Ecology rules.

Construction Stormwater General Permit

Construction Stormwater General Permit

Construction site operators are required to be covered by a Construction Stormwater General Permit if they are engaged in clearing, grading, and excavating activities that disturb one or more acres and discharge stormwater to surface waters of the state. Smaller sites may also require coverage if they are part of a larger common plan of development that will ultimately disturb one acre or more. Operators of regulated construction sites are required to:

  • Develop stormwater pollution prevention plans.
  • Implement sediment, erosion, and pollution prevention control measures.
  • Obtain coverage under this permit.
