<br />EXHIDIT G -- Water Information--This information has not changed from the original permit in <br />as far as surface and subsurface water considerations. The original permit document should be <br />referenced for this information. Stormwater management aspects, however, were scrutinized in <br />detail in 1994 by DMG, which resulted in TR-O1 Technical Revision to Permit M-77-247, This <br />included the design and construction of storm ditches, sediment ponds, and spillway devices to <br />contain and handle 10, 25, and 50 year storm events on the property without allowing a <br />stormwater outfall to leave the property boundaries. The specific storm watershed calculations <br />and other criteria developed for the Technical Revision are now part of the original permit <br />package and can be referenced as such. At the completion of closure work on the site, the <br />current crusher site will become a large stormwater containment area, capable of holding up to <br />four acre feet of stormwater prior to controlled release of the stormflows to a lined dual system <br />armored storm ditch, which will convey the stormflows to an additional one acre sediment pond <br />prior to controlled release. This system of stormwater control is designed to handle anticipated <br />storm volumes and peak discharges up to 100 year storm events without allowing stormwater to <br />leave the property boundaries. <br />
