SECTION B <br />The following findings and specific approvals are required by Rule 4. <br />No specific approvals are granted under this section. <br />No specific approvals are granted under this section. <br />A. Water Quality Standards and Effluent Limitations <br />The Division proposes to grant small area exemptions from use of <br />sediment ponds due to the limited size of the area and due to the fact that <br />ponds and/or treatment facilities are not necessary for the drainage in <br />these specific areas to meet the effluent limitations of Rule 4.05.2 and <br />applicable State and Federal water quality standards for receiving streams <br />and also due to the fact that no mixing of surface drainage with a <br />discharge from underground workings will occur. The small areas to be <br />exempted are located as follows: <br />West Portal Substation <br />West Portal Core House <br />East Portal Water Tanks <br />West Portal Water Tanks Areas 1 and 2 <br />West Portal Pumphouse <br />Topsoil pile north of the river and west of the RDA belt (4.05.2(3)(b)(i)). <br />B. Stream Channel Diversions <br />The Division proposes to approve the diversion of a perennial stream <br />draining at least one square mile. This decision is based on a finding that <br />the proposed diversion meets the requirements of 4.05.18 and 4.05.4, <br />applicable local, State, and Federal statutes and regulations and that the <br />diversion is designed to safeguard public safety and to minimize adverse <br />impacts to the hydrologic balance. The Middle Fork of the Purgatoire <br />River was permanently diverted in order to construct the coal preparation <br />plant (4.05.4(1) and (4)). <br />17 <br />
