:.._ ,~ _ u :, , „ .,., .~ ~=~- _ N. =?~ ~ - ~ UNDERSTANDING I Both parties have specific and separate statutory reaponeibillties to review permit applications, monitor and inspect field sites, and take enforcement action. The parties exercise of their respective reaponeibilitLee has the potential for duplication and inconsistent actions by the parties in the management of hydrologic balance and water quality issues with respect to the responsibilities. This MOII addressee each area of responsibility separately. Review of Permit Applications The parties will coordinate the review of hydrologic information submitted within a coal mining permit application with respect to information relevant to Colorado Discharge Permit.Syetem (CDPS) permits for process/mine water and atormwater pint w en a e o ow ng: 1. During pre-application meetings with potential coal mine permit applicants, each party will advise the applicant of the need to contact the other party. 2. DMG will review the coal permit applications to determine whether the sediment control structures will be designed to meet technology based effluent limitations and that any atormwater control technologies are in conformance with the Rules and Regulations for Coal Mining, CRS 34-33-101. 3. The parties will confer, ae appropriate, during the course of permit review and drafting to coordinate where there may be duplication or potential conflict, and to keep each party apprised of technical developments. 4. WQCD will provide DHG with copies of all final CDPS permits actions for coal mines, at the time of action issuance. Conversely, DMG will provide WQCD copies of all notices of final action on coal mining permits. Training WQCD will provide water quality sample collection training to DMG staff upon the request of DMG. Each party will also provide general inspection training upon the request of the other party. Inactions, Monitoring and Sample Analveie The parties will coordinate inspections, monitoring and sample analysis in the following manner: i. In those instances where effluent violations are suspected, DMG shall collect water quality samples at CDPS discharge points during the course of conducting its normal site inspection obligations. In those instances where DMG suspects an unpermitted discharge, DMG shall collect a water quality sample for analysis. 2. DMG shall include in its inspection reports which accompany a sample result specified in item 1 of this section a detailed description of site conditions and a discussion as to whether a precipitation event has occurred at the site within the preceding 24 hours. 3. To the extent funds allow, WQCD shall pay for the cost of analysis for samples collected pursuant to item 1 of this section. Such samples are to be delivered to the Laboratory Division of the Colorado Department of Health for analysis. DMG shall absorb the cost of obtaining the samples and transmitting them to the lab. 4. Sample collection by DMG shall Follow all chain-of-custody and other normal enforcement procedures to ensure sample integrity. 2
