Re: Cooley Reservoir & Fulton Wildlife Area, Amendment Approval, Permit No. M-1999-034, Revision
No. AM-1
Dear Mr. Refer:
On June 25, 2003 the Colorado Mined Land Reclamation Boazd, considered the Division's recommendation and
approved the Amendment application submitted to the Division on February 12, 2003, addressing the following:
Add 5011 acres to permit area.
The terms of the Amendment No. 1 approved by the Division aze hereby incorporated into Permit No. M-1999-
034.
The conditions of the Boazd approval are noted below. Please note that all other provisions of Permit No. M-1999-
034 remain in full force and effect.
Stipulation No. Description
1 No de-watering or exhaction activities will occur until Aggregate Industries develops a plan to
monitor the gravel pit water for diisopropyhnethylphosphonate (DIIvIP) and obtains approval of that
plan from the Division of Minerals and Geology., The plan will include mondily sampling and
analysis to begin immediately after de-watering and/or extraction activities aze started. The montldy
monitoring will continue for one yeaz and then will change to quarterly monitoring until the
Division issues a letter authorizing discontinuance. The plan will include the sampling and
analytical methods to be used and an agreement to submit the results of the anaylsis to the Division
within 30 days of the sampling date. The samples will be obtainded and analyzed by a company,
individual, or agency certified to do the work. If an analysis shows a level of DIMP exceeding
8ug/L, Aggregate Industries or its agent will immediately notify the Division by certified mail and
include a response plan to deal with the contaminant, and to prevent on-site and off-site damage. If
the Division detemlirles from the monitoring data that there is a reasonable potential for the
operation to cause groundwater quality standazds for DIMP to be exceeded, the Division will notify
Aggregate Industries to modify the pemTit as necessary to comply with Subsection 3.1.7 of the
Rules.
2 Aggregate Industries-WCR, Inc. will monitor the Kazen Topper shallow well (well permit no. 2455)
for dusopropylmenthlyphosphonate (DIMP) initially before mining activities start in the
Amendment No. 1 area and again after de-watering stazs. The monitoring will be done with the
permission of the landowner initially given to Aggregate Industries by Ms. Topper's brother, Steve
Brancucci, at a hearing before the Colorado Mined Land Reclamation Boazd, on June 25, 2003.
