2. Immediately begin the process to fully implement and maintain appropriate source <br /> control and/or treatment BMPs as soon as possible. Address the problems within 10 <br /> days of the date the discharge exceeded the benchmark. If installation of necessary <br /> treatment BMPs is not feasible within 10 days, Ecology may approve additional time <br /> when the Permittee requests an extension within the initial 10-day response period. <br /> 3. Document BMP implementation and maintenance in the site log book. <br /> If the turbidity exceeds 250 NTU or the transparency is 6 cm or less at any time, the following <br /> steps will be conducted: <br /> 1. Telephone or submit an electronic report to the applicable Ecology Region's <br /> Environmental Report Tracking System (ERTS)within 24 hours. <br /> • Central Region (Benton, Chelan, Douglas, Kittitas, Klickitat, Okanogan, <br /> Yakima): (509) 575-2490 or <br /> http://www.ecv.wa.pov/proarams/spills/forms/nerts online/CRO nerts online.html <br /> • Eastern Region (Adams,Asotin, Columbia, Ferry, Franklin, Garfield, Grant, <br /> Lincoln, Pend Oreille, Spokane, Stevens,Walla Walla,Whitman): (509) 329-3400 <br /> or http://www.ecy.wa.aov/proarams/spills/forms/nerts online/ERO nerts online.html <br /> • Northwest Region (King, Kitsap, Island, San Juan, Skagit, Snohomish, <br /> Whatcom): (425)649-7000 or <br /> http://www.ecy.wa.gov/programs/spills/forms/nerts online/NWRO nerts online.html <br /> • Southwest Region (Clallam, Clark, Cowlitz, Grays Harbor, Jefferson, Lewis, <br /> Mason, Pacific, Pierce, Skamania, Thurston,Wahkiakum,): (360)407-6300 or <br /> http://www.ecy.wa.qov/programs/spills/forms/nerts online/SWRO nerts online.html <br /> 2.

Document BMP implementation and maintenance in the site log book. <br /> 4. Continue to sample discharges daily until one of the following is true: <br /> • Turbidity is 25 NTU (or lower). <br /> • Transparency is 33 cm (or greater). <br /> • Compliance with the water quality limit for turbidity is achieved. <br /> 0 1 - 5 NTU over background turbidity, if background is less than 50 NTU <br /> 0 1% - 10% over background turbidity, if background is 50 NTU or greater <br /> • The discharge stops or is eliminated. <br /> Page � 28 <br />
