DESCRIPTION OF AMENDMENT <br />By lever dated June 16, 1998, the permittee requested deletion of two outfa[!s, numbers 016 and 017. Outfa!! 016 is the <br />discharge point for Pond M; outfail 017 is the discharge point for Pond K. Both outfalls have been approved for <br />removal from the permiaee's surface runoff treatment system by the Colorado Division of Minerals and Geology <br />(CDMG). And, by letter dated August 18, 1999, the permiltee requested deletion of outfall number 010. This outfall is <br />the discharge point for pond M3S. Final bond release for these three sites, as well as for pond M3N covered under <br />general permit certificarion number COG-850013, has been granted by the CDMG. <br />The surface property owner of the area upon which Pond M is located has asked that this pond remain in place <br />permanently for use as a stock watering pond. This pond's outfall would na longer serve as a discharge point from an <br />industrial facility; it is considered to 6e a discharge from an agricultural operation and, as such, is exempt from <br />Colorado Discharge Permit System (CDPS) requirements. The CDMG has approved of the pond remaining for this use. <br />The permittee is the owner of the property upon which Pond K is located. Pond K is required to be removed under the <br />CDMG approval. The pond area will be reclaimed. <br />The CDMG has alto approved Pond M3S (outfall 010) to remain as a stock watering pond, thus it will also remain after <br />ftnal bond release. <br />Table 11-1 indicates that spoils springs may be sources to Ponds M3S and M (outfalls 010 and 016, respectively). This is <br />because the permittee, when they applied for authorization for these outfal[s, believed that the possibility existed for <br />spoils springs to develop that might contribute to the discharges. <br />CORRECTED SEP 24. 1 999 <br />
