Monitoring and Reporting <br />Tab 13, Hydrologic Monitoring Program, provides details of pact and proposed efforts *ega~++ <br />monitoring oP local ground and s,.'caw water. Both surfaw and ground water monitoring sites <br />rill be maintained for the life of the loadout facility or until such time as CDbT. may agree that <br />they era no longer newssary. After consultation with CDtT. aurfaw water monitoring at Site <br />HGSD2 ceased following April 1994. Monitoring of ground water from walls HGDALl and H(~AI.2 <br />ceased following October 1995. The monitoring at these stativea ceased in acmrdanca with the <br />monitoring plan outlined in Tab 13. In additive, monitoring at the outfalla of Panda 1 and 2 <br />(OOlA and 002A) will be conducted during the life of the facility in accoxdanca with the terms <br />and conditives of NPDES Permit No. COG-850008 (see Appendix 13-1, Tab 13). <br />All surfaw and ground water data collected at each monitoring nits in each Future calendar year <br />(January through December) will be oongailed and submitted to the CDAG in the foe of the HGT <br />Ioadout Facility Annual Hydrology Report (AHR) by March 1 following calendar year. <br />Stream Buffer Zones <br />A.v defined in Section 4.05.18 of the Colorado Surfaw Coal Mining Reclamative Act, the m: r; <br />operative shall not disturb the Stream buffer zone within 100 feet of a pezannial stream or <br />stream with a biological cr.,.~...+ty. Dry Creek ie not categorized an ro ~~~, although during <br />wet years wr'tain reaches may flow year rrnu~d. The stream is intermittent. The available fish <br />and wildlife resources information indicates that a biological comity ae defined at sh.ie <br />4.05.18(3), is present (sea Tab 11). In additive, the U. S. Fish and Wildlife Serviw has <br />verbally indicated they would like to sea habitat associated with Dry Creek protected (sea Tab <br />11). '~'~+oroFOra, a stream buffer zone hna bean eatabliahed along Dry Creek (see Tab 21). <br />Diaturbanws within and immediately adjawnt to Dry Creek are limited to the following existing <br />atrvetures: 1) two railroad crossings of Dry Creak, and 2) sediment pond 002. The railroad <br />Ci0991nga and the a°'~'^`°^t pond have b60i1 de9lgned and COi19tNCted t0 `^ ~^i Ze diaLVrbanw9 tD <br />the stream segment. The original main channel of Dry Creek has not bean either diverted or <br />realigned at any of the above mentioned stxucturas. The railroad crossing culverts and the <br />ad++~~t pved are properly designed (rill venveY the runoff o£ a 10-year, 24-hour storm) to <br />prevent water quality degradation in Dry Creek an a result of the embankment diaturbanws. No <br />additional charmel disturbances are contemplated. <br /> <br />3 <br />RN-ol <br />Revised 2/98 <br />
