iii. Document BMP implementation and maintenance in the site log book. <br /> b. Turbidity 250 NTUs or greater,or Transparency 6 cm or less: <br /> If a discharge point's turbidity is 250 NTUs or greater, or if discharge <br /> transparency is less than or equal to 6 cm,the Permittee must complete the <br /> reporting and adaptive management process described below. <br /> i. Telephone or submit an electronic report to the applicable Ecology <br /> Region's Environmental Report Tracking System (ERTS)number(or <br /> through Ecology's Water Quality Permitting Portal [WQWebPortal] — <br /> Permit Submittals when the form is available)within 24 hours, in <br /> accordance with Special Condition S5.A. <br /> • Central Region(Okanogan,Chelan,Douglas,Kittitas,Yakima, <br /> Klickitat, Benton): (509) 575-2490 <br /> • Eastern Region(Adams,Asotin,Columbia,Ferry,Franklin,Garfield, <br /> Grant, Lincoln,Pend Oreille, Spokane, Stevens,Walla Walla, <br /> Whitman): (509) 329-3400 <br /> • Northwest Region(Kitsap, Snohomish,Island,King, San Juan, <br /> Skagit, Whatcom): (425) 649-7000 <br /> • Southwest Region(Grays Harbor,Lewis,Mason,Thurston,Pierce, <br /> Clark, Cowlitz, Skamania,Wahkiakum, Clallam,Jefferson,Pacific): <br /> (360)407-6300 <br /> Links to these numbers and the ERTS reporting page are located on the <br /> following web site: <br /> http://www.ecy.wa.gov/programs/wq/stormwater/construction/index.html. <br /> ii.

Immediately begin the process to fully implement and maintain <br /> appropriate source control and/or treatment BMPs as soon as possible, <br /> addressing the problems within 10 days of the date the discharge <br /> exceeded the benchmark. If installation of necessary treatment BMPs is <br /> not feasible within 10 days,Ecology may approve additional time when <br /> the Permittee requests an extension within the initial 10-day response <br /> period. <br /> iv. Document BMP implementation and maintenance in the site log book. <br /> v. Sample discharges daily until: <br /> a) Turbidity is 25 NTUs(or lower); or <br /> b) Transparency is 33 cm(or greater); or <br /> Construction Stormwater General Permit <br /> Page 18 <br />
