SECTION B <br />The following findings and specific approvals are required by Rule 4 <br />I. Hydrologic Balance - Rule 4.05 <br />A. Water Quality Standards and Effluent Limitations <br />The applicant has demonstrated that sediment ponds and/or <br />treatment facilities are not necessary for drainage to meet the <br />effluent limitations of 4.05.2 and the applicable State and <br />Federal water quality requirements for downstream receiving <br />waters. Therefore the Division proposes to grant an exemption <br />from these requirements. This exemption applies to the entire <br />site due to demonstration made by Coors that there was no <br />evidence of surface water flow on the site. (See Appendix K for <br />study). See permit Section 2.03.8, pages 32a and 32b and <br />Technical Revision 23 approved 12/18/89. (4.05.2(3)(a)). <br />B.

The ground water monitoring <br />plan is as follows: (4.05.13(1)). <br />Monitoring We11s <br />The table below summarizes well designation, top of casing elevation <br />and aquifer monitored during 1991. <br />Well <br />Elev.
