standards for receiving streams. These areas have also been exempted because no <br /> mixing of surface drainage with a discharge from underground workings will <br /> occur. Three small area exemptions are permitted for the three topsoil stockpiles <br /> (TS-1, a portion of TS-2, and TS-3) associated with the loadout and six topsoil <br /> stockpiles (A, C, D, E, F, and G) and one temporary waste stockpile (TWS) <br /> associated with the TAHR outside the sediment control system. The remaining <br /> SAES consist of the rail loop, drainage from an electrical substation located at the <br /> previous office trailer location, the office/parking lot/leach field, two areas <br /> designated as "areas 1 and 2" on Exhibit 12-2 of the PAP, and H-G shallow well <br /> and associated pipeline corridor. Documentation of these exemptions is found in <br /> Volume 12, Tab 12 of the permit application (4.05.2(3)(b)(i)). <br /> B. Diversions and Conveyance of Overland Flow <br /> All diversions within the permit area are designed and constructed in accordance <br /> with Rule 4.05.3. Designs are discussed in the text and diversion locations are <br /> displayed in Exhibit 12-1 and Exhibit 12-2 of Volume 2, Tab 12 of the PAP <br /> (4.05.3). <br /> C. Stream Channel Diversions <br /> No stream channels are proposed to be permanently diverted. <br /> D. Sedimentation Ponds <br /> Two sediment ponds are in place as previously approved by the Division and have <br /> been treating disturbed area surface water runoff under the existing permit for the <br /> Loadout. These ponds are the Truck Loop Pond(Pond A) and Railway Loop <br /> Pond(Pond B). The Truck Loop Pond was fitted with a separate secondary <br /> spillway in 1992 (a separate secondary spillway was not necessary for the Rail <br /> Loop Pond due to the size and configuration of its single spillway). Designs for <br /> these ponds are included in Volume 2, Tab 12,Appendix 12-1 and locations of <br /> the ponds are displayed on Exhibit 12-2 of the PAP. <br /> E. Acid-forming and Toxic-forming Spoil <br /> No coal is being mined at the site; therefore,there is no acid-forming or toxic- <br /> forming spoil. Prior to backfilling the site, all debris and coal fines were disposed <br /> of in a manner that prevented contamination of surface and ground water <br /> F. Impoundments <br /> No impoundments other than two sediment ponds are proposed. <br /> G. Surface and Ground Water Monitoring <br /> 18 <br />
