o Backfill the remainder of the hole with cuttings or other suitable material <br />and regrade the associated surface area. <br />o Broadcast approved seed mixture on associated disturbance areas. <br />EFCI is responsible for the sealing and site reclamation for all holes drilled by <br />Dorchester and Energy Fuels. Appropriate abandonment and reclamation <br />reports, utilizing all available information, will be filed with the Division for all <br />holes that are EFCI's reclamation responsibility. <br />Compliance With Applicable Air and Water Oualitv Re4ulations <br />EFCI's ongoing mining and reclamation plans have been designed to effect <br />compliance with applicable air and water quality regulations. Compliance is <br />effected by a variety of control and mitigation measures aid is documented by <br />comprehensive monitoring programs. <br />Compliance with applicable Federal, State and local water regulations is a result <br />of design and implementation of the comprehensive drainage and sediment <br />control plan as described in this permit text and detailed by Exhibit 19, <br />Drainage and Sediment Control Plan. Ongoing monitoring programs, and <br />operation under the provisions of NPDES discharge permits (Permit Nos. <br />CO-0036595 and CO-0037109) issued by the Colorado Department of Health <br />are also important components of EFCI's ongoing compliance efforts. Operation <br />under and compliance with the NPDES permits effects compliance with both the <br />Federal Clean Water Act and the Colorado Water Quality Control Act. A detailed <br />discussion of hydrologic control and mitigation measures is presented in Section <br />2.05.6, Mitigation of Surface Mining Operation Impacts. <br />Compliance with applicable air quality regulations is effected by operational <br />control and mitigation measures and operation under the provisions of air <br />emissions permits issued by the Colorado Department of Health. EFCI does not <br />operate any point source generators, consequently any air emissions are limited <br />to fugitive dust emissions from surface refuse disposal operations, crushing and <br />coal preparation activities, and coal stockpiling and reclaim activities. EFCI has <br />not experienced any significant problems with fugitive dust emissions from any <br />mining or related operations. The primary controlling factor is the significant <br />percentage of surface moisture in coal and refuse materials which limits <br />potential dust emissions. In addition, all coal processing activities involve wet <br />processing so dust generation is not a problem. <br />2.05.4-31 Revised 10/04/07 <br />MR-55 <br />
