The condition is as follows and has been agreed to by Aggregate Industries. <br />CONDITION OF APPROVAL <br />No de-watering or extraction activities will occur until Aggregate Industries develops a plan to monitor the gravel pit pond water <br />for diisopropyhnethylphosphanate (DIlVIP) and obtains approval of that plan from the Division of Minerals and Geology. The plan <br />will include monthly sampling and analysis to begin immediately after de-watering and/or extraction activities aze started. The <br />monthly monitoring will contimte for one yeaz and then will change to quarterly monitoring until the Division issues a letter <br />authorizing discontinuance. The plan will include the sampling and analytical methods to be used and an agreement to submit the <br />results of the analysis to the Division within 30 days of the sampling date. The samples will be obtained and analyzed by a <br />company, individual, or agency certified to do the work. If an analysis shows a level of DIMP exceeding Sug/L, Aggregate <br />Industries or its agent will immediately notify the Division by certified mail and include a response plan to deal with the <br />contaminant, and to prevent on-site and off-site damage. If the Division determines from the monitoring data that there is <br />reasonable potential for the operation to cause groundwater quality standazds for DIMP to be exceeded, the Division will notify <br />Aggregate Industries to modify the permit as necessary to comply with Subsection 3.1.7 of the Rules. <br />Attached to this letter is the Division's Rationale for Recoltttnending approval over objections. <br />If you have questions concerning this recommendation, please call me at (303) 866-4922. <br />Sincerely, ~,c/~~ ~ ~~ <br />Lai7}r ll.
