9.24.030 Storm water pollution prevention plan (SWPPP).
A storm water pollution prevention plan (SWPPP) shall be prepared for all projects meeting the state regulatory threshold. The SWPPP shall be implemented beginning with initial soil disturbance and shall apply until final stabilization after completion of construction. Refer to Sections 9.D and 9.E of the construction storm water general permit for detailed instructions on how to complete a construction SWPPP.
(1) The storm water pollution prevention plan shall include each of the following twelve elements below in the narrative of the SWPPP and ensure that they are implemented unless site conditions render the element unnecessary and the exemption from that element is clearly justified in the SWPPP.
(A) Preserve vegetation/mark clearing limits;
(B) Establish construction access;
(C) Control flow rates;
(D) Install sediment controls;
(E) Stabilize soils;
(F) Protect slopes;
(G) Protect drain inlets;
(H) Stabilize channels and outlets;
(I) Control pollutants;
(J) Control de-watering;
(K) Maintain BMPs
(L) Manage the project;
(2) Construction site operators must maintain and repair, as needed, all sediment and erosion control BMPs to assure continued performance of their intended function.
(3) For projects meeting the state regulatory threshold, construction site operators must periodically have their site inspected by a certified erosion and sediment control lead (CESCL) who shall be identified in the SWPPP and shall be present on-site or on-call at all times. The city of Selah public works director, or his/her designated representative, shall inspect projects smaller than one-acre.
(4) Construction site operators must maintain, update and implement their SWPPP. Modifications to the SWPPP must be made and submitted to the Washington Department of Ecology, with a copy to the city, whenever there is a change in design, construction, operation, or maintenance at the construction site that has, or could have, a significant effect on the discharge of pollutants to waters of the state.
(5) For projects meeting the state regulatory threshold, construction site operators must comply with all storm water monitoring and testing requirements as stated in the Section 4 of the construction storm water general permit. (Ord. 1800, § 1, 2010.)
