You had requested guidance from the Water <br /> Quality Control Division(WQCD) on acceptable reclamation criteria for the above-referenced site, <br /> under a stormwater discharge permit. <br /> The criteria as outlined in your letter will be acceptable for allowing termination of discharge permit <br /> coverage, once the vegetation has become established. I have attached a copy of the tent from the <br /> stormwater Metal Mining permit(which also covers coal mines)that is relevant to this situation. <br /> .Also note that the basic underlying tenet for coverage of mines is that a stormwater permit is <br /> required only if runoff contacts overburden,raw material,intermediate or finished products, or watte <br /> products,and is then discharged to state waters. It sounds as if completion of the process described <br /> in your letter will eliminate the need for a permit. <br /> It is important to be very clear about what sites will be covered under the Division of Minerals and <br /> Geology's stormwater permit,and what sites will remain under Mid-Continent's industrial discharge <br /> permit. This should be specified in the permit application,as well in as the Stormwater Management <br /> Plan(SWMP). I have enclosed a copy of the application for your use, as well as a copy of the <br /> guidance document for preparing a SWMP. <br /> Exhibit E to Settlement Ag <br />
