14. No dewatering or extraction activities will occur until Aggregate Industries develops a plan
to monitor the gravel pond water for diisopropylmethylphosphonate (DIl~]P) and obtains
approval of that plan from the DMG. The plan will include monthly sampling and analysis
to begin immediately after dewatering and/or extraction activities are started. The monthly
monitoring will continue for one year and then change to quarterly monitoring, until the DMG
issues a letter authorizing discontinuance. The plan will include sampling and analytical
methods to be used and an agreement to submit the results ofthe analysis to the DMG within
30 days of the sampling date. The samples will be obtained and analyzed by a company,
individual, or agency certified to do the work. If an analysis shows a level of DIIvIP
exceeding 8ug/L, Aggregate Industries or it's agent will immediately notify the DMG by
certified mail and include a response plan to deal with the contaminant, and to prevent on-site
and off-site damage. If the DMG determines from the monitoring data that there is a
reasonable potential for the operation to cause groundwater quality standards for DIMP to
be exceeded, the DMG will notify Aggregate Industries to modify the permit as necessary to
comply with Subsection 3.1.7 of the Rules.
