HB 2731 - DIGEST

Authorizes the department to issue storm water general permits under the national pollution discharge elimination system of the federal clean water act if such permits are required to comply with federal standards or are necessary for the effective implementation of chapter 90.48 RCW. However, the permits are subject to the following conditions: (1) The implementation and maintenance of best management practices for on-site pollution control is presumed to constitute compliance with the standards and requirements of the permit, subject to the conditions of this act.

(2) For purposes of storm water discharges, meeting effluent discharge limits must be demonstrated through implementation of best management practices sufficient to equate to all known and reasonable treatment. The department may monitor best management practices, for as long as deemed necessary, to determine their effectiveness in managing pollutants in storm water.
