(1) To guide stormwater standards and BMP selection for development, the City adopts, by reference, definitions, minimum requirements and exceptions, adjustment and variance criteria found in Appendix 1 of the most current NPDES Eastern Washington Phase II Municipal Stormwater Permit (NPDES Phase II Permit), including the mandatory incorporated provisions of the Stormwater Management Manual for Eastern Washington (2004), as amended. The regulatory thresholds and other requirements are as described in Appendix 1 of the NPDES Phase II Permit and the most currently adopted City of Pullman Design Standards except where superseded within Sections 10.32.050 and 10.32.060 of this Chapter. All Large Projects shall follow all requirements of the Stormwater Management Manual for Eastern Washington (2004), as amended, except where superseded in Appendix 1 of the NPDES Phase II Permit, or this Chapter. Unless the context requires otherwise, references to the local jurisdiction shall be construed to mean the City of Pullman.

(2) The most currently adopted City of Pullman Design Standards shall be used when developing ESC Plans and determining the design storms and the minimum requirements, thresholds and standards for designing permanent stormwater collection, conveyance, flow control and treatment facilities and BMPs.

(3) Use of BMPs not designed, constructed, and maintained in accordance with the design manuals and/or guidance documents identified in Section 10.32.080(1) and (2) shall be subject to Administrator approval and must be monitored for performance to demonstrate that they meet the minimum flow control and water quality performance standards of the NPDES Phase II Permit requirements.
