COLORADO DEPARTME.._ OFHEALTHAND ENVIRONMENT, Water L___lity Control Division Rationale-Page 3, Permit No. CO-0044768 B. Monitoring and Reporting The permittee is required 10 perform whatever oversight is necessary to insure that the MRP is being implemented, and shall comply with all monitoring and reporting conditions included in the MRP. At a minimum, monthly reports are required for any water quality data that is collected as part of a MRP.In addition, quarterty reports must be submitted which include: 1) a narrative description of the current status of the remediation project, 2)a summary of analytical results for any sampling that was specified in the AMP for the site in question, 3)a photographic survey of the sites(both pre-remediation waste location and post-remediation waste location) involved in the remediation action. Reports must be received by the 28th day of the month following the calendar quarter or month for which the report is being submitted. C. Legal Right To Enter Prior to beginning on-site work for any remediation project, the permittee must submit documentation to the Water Quality Control Division showing that the permittee has been granted permission to enter the property(ies) where work will be carried out. D. Termination This mine remediation projects permit may be terminated in accordance with the terms of the Consent Decree when the remediation projects are completed. V. CHANGESMADE AFTER PUBLIC NOTICE Three Sunnyside Gold Corporation permits were sent to public notice-CO-0027529, which is for the American Tunnel discharge, CO-0036056, which is for the Terry Tunnel discharge, and CO-0044768, which is for mine remediation projects in the Upper Animas basin. In addition, a related draft Consent Decree that has been negotiated between the Division and the mining company was in the same public notice. Responses to the public notice were received from private citizens, a committee of members of the Animas River Stakeholders group, several environmental and mining industry oriented groups, several governmental agencies, and the Sunnyside Gold Corporation itself. Most of the comments received were related to the consent decree, which is being dealt with separately from the discharge permits. With respect to this discharge permit, the following issues were raised: 1) Comment: The CDPS permits must function as stand alone documents, regardless of the existence of the consent decree. Response: The permits were reviewed to find any terms or conditions that through reference were dependent upon the contents of the consent decree. Where such permit conditions were found, they were revised to more explicitly describe the intended permit requirements. However, there is one exception to this that should be noted. Each draft permit included a termination clause which referred directly back to the consent decree. While this clause was modified to additionally require compliance with State permit regulations, it was determined that it would not be practical to include the consent decree's conditions related to permit termination within the permits themselves. Also, the termination clauses do not affect the enforceability of the permits. For these reasons, the termination clauses'references to the consent decree were retained. 2) Comment. The draft permit for Mine Remediation Projects should include criteria for what must be included in a Mine Remediation Plan (AMP). Such criteria should be similar to those that have been developed for the draft General Permit for Stormwater Discharges Associated with Metal Mining Operations and Mine-Waste Remediation (Permit Number COR-040000, Parts LC.1. -LC.6), with particular emphasis on erosion control during and after the project.
