Establishes a presumption of compliance for entities under the industrial stormwater general permit if they meet permit conditions and implement best.

The bill establishes a presumption of compliance for entities covered under Washington's industrial stormwater general permit, provided they are in full compliance with permit conditions and fully implement stormwater best management practices. The Department of Ecology must notify permittees in writing if a discharge caused or contributed to a potential violation of water quality standards. The bill aims to mitigate adverse impacts such as third-party litigation and health and safety concerns for employees.
