The Eastern Washington Phase II Municipal Stormwater Permit required Permittees to have programs to control runoff from new development, redevelopment. These programs are required to include a review of stormwater site plans for development activities. The WSC partnered with the Department of Ecology to develop a Plan Reviewer Training. This training is intended to provide municipal staff whose primary function is to review plans for a general overview of how to review a plan set to ensure compliance with the Permits.
