• violation of permit No. M-88-112. However, the Board ordered BMRI to submit a Technical <br />Revision to the permit proposing specific actions by BMRI and a schedule of their <br />implementation which will provide for the future protection of ground and surface water quality <br />in the area of the West Pit. <br />6. BMRI complied with the Board Order by submitting TR-26 on April 8, 1999. Division records <br />indicate that copies of TR-26 were sent to all the concerned parties, as required by the Board <br />Order. On May 7, 1999, the Division received a wavier of the 30-day decision period from <br />BMRI. TR-26, and comments from the concerned parties, were reviewed by the Division. An <br />adequacy letter was sent to BMRI on May 26, 1999. <br />7. On May 24, 1999, the Division received a request from BMRI for partial approval of TR-26. <br />Specifically, BMRI requested the approval of the evaporation system so remediation activities at <br />the West Pit could initiate during the hot, dry summer months. BMRI submitted responses to the <br />Division's adequacy letter (for the evaporation system) including accurate engineered drawings <br />and maps of the proposed facility. <br />8. The Division approved the evaporation system on June 1, 1999 after BMRI adequately <br />addressed all the technical, geotechnical and engineering aspects of the system. BMRI was not <br />allowed to start the system until the water rights issues were resolved. The Division received a <br />copy of a letter (dated June 7, 1999) on June 14, 1999 from the Division of Water Resources <br />which stated that the State Engineer determined that BMRI's currently approved augmentation <br />• plan sufficiently addressed the amount of water that may be consumed by the evaporation system <br />in the Wes[ Pit. The letter was accepted by the Division as compliance with [he requirement to <br />minimize disturbances to the hydrologic balance pursuant to CRS 34-32-116(7)(g) and Rule <br />3.1.6. BMRI was notified on June 15, 1999 by the Division that the evaporation system can be <br />initiated as soon as it is constructed. <br />9. As of July 8, 1999, BMRI is pumping groundwater from three alluvial aquifer wells (M-18,19 <br />& 28) at a stabilized combined rate of approximately 92 gpm. The water is pumped into a lined <br />collection pond. In addition, during the July 4th weekend, BMRI began pumping two backfill <br />wells (BF-3 and BF-4) at approximately 235gpm and 225 gpm, respectively, into the collection <br />pond. Since only 2 snow blowers were operating, and because the collection pond was over half <br />full, the backfill wells were shut down on the 6th of July. After all five snow blowers are <br />operating (evaporating approximately 60 gpm each), the backfill wells will be re-started. <br /> <br />I0. As of July 15, 1999, BMRI is pumping groundwater from four alluvial aquifer wells (M-18, <br />19, 28 & 29) at a stabilized combined rate of approximately 92+gpm. All five snowblowers were <br />operating on July 15th. BMRI was pumping nearly 400 gpm to the five evaporators. BMRI was <br />in the process of constructing a super spray system on the west side of the snowblowers which <br />can handle up to 600 gpm. This system will spray the groundwater onto the lined area so the heat <br />of the black liner will increase evaporative losses. The system is no[ very efficient but will <br />increase removal of the contaminated ground water. Results of the evaporation system's success <br />• should be available in the next month or so. <br />
