Light Use Roads <br />Light use roads have been designed and constructed in accordance with Rule 4.03.3(7). Some <br />light use roads are permitted to be left in support of approved post -mining land use. <br />IV. Rule 4.04 Support Facilities <br />No new support facilities are anticipated on the site. The construction of existing support <br />facilities has not damaged or caused disruption of any pipelines, railroads, or utility lines that <br />pass over, under, or through the permit area. The Division approved the existing facilities [Rule <br />4.04(6)]. <br />Several gas wells have been installed within the permit area by third parties. The gas companies <br />maintain these well sites and access to the wells. These locations have been classified as <br />industrial land use. Reclamation of the well sites is the responsibility of the gas companies, and <br />this responsibility is stated in the contracts between them and CEC. <br />V. Rule 4.05 Hydrologic Balance <br />Water Quality Standards and Effluent Limitations <br />CEC has established drainage systems, including sediment ponds, to meet the applicable State <br />and Federal water quality requirements for downstream receiving waters [Rule 4.05.2]. <br />There is currently no surface water monitoring at the Keenesburg Mine Site, because there is no <br />point of surface water discharge. On December 18, 1989, Technical Revision 23 approved the <br />deactivation of the Colorado Discharge Permit System (CDPS) permit, and the Department of <br />Health (former name of CDPHE) concurred with this decision. Permit COG -850038 was later <br />reinstated with an expiration date of June 30, 1997. CEC again proposed, and CDPHE approved, <br />the expiration of the CDPS permit without renewal (the CDPHE letter regarding the Request for <br />Inactivation of this permit can be found in Division files). <br />Because of the limited size of certain small disturbed areas, (topsand storage and reference area <br />sites), The Division proposes to continue the approved exemption from the requirement to have <br />runoff from these areas report to sediment ponds. Also, ponds and treatment facilities are not <br />necessary for drainage to meet the effluent limitations of Rule 4.05.2 and applicable State and <br />Federal water quality standards for receiving streams. As there are no underground workings <br />within the permit area, mixing of surface drainage from these areas with discharge from <br />underground workings will not occur. The small areas to be exempted are described in the Index <br />Maps and Legal Description sections of the Permit [Rule 4.05.2(3)(b)(i)]. <br />Ground Water Monitoring Plan <br />The following ground water monitoring plan is required by Rule 4.05.13(1). <br />Monitoring Wells <br />The table below summarizes well information.
