The pilot project is part of <br /> Varra's proposed reclamation plan for areas previously mined for gravel in Weld County. In accordance <br /> with the Solid Waste Statute (CRS 30-20-103), and with the Solid Waste Regulations (the Regulations) <br /> promulgated thereunder, 6 CCR 1007-2, a preliminary completeness review of such application is <br /> required within thirty (30)days of receipt. <br /> The Division has completed its 30-day review of the application. In the judgement of the Division, the <br /> application is incomplete and will require further modification/revision to adequately meet the <br /> requirements of the Regulations. Furthermore, based on the information and data provided, the Division <br /> cannot make a favorable determination on the submitted application. <br /> The unfavorable determination is discussed below: <br /> Table 6 of the Work Plan provides a summary of the SELP coal ash analytical results which exceed <br /> water quality standards established pursuant to Colorado's"The Basic Standards For Ground Water", <br /> Regulation #41, (5 CCR 1002-41). In addition, results of other analytical methods (TCLP, SGCLP, <br /> SGLP) show numerous constituents leaching from coal ash which exceed a relevant groundwater <br /> standard. The analytical data unequivocally shows degradation of the groundwater will occur if coal ash <br /> is placed in a saturated medium. Placing a waste, which has been demonstrated to leach pollutants, <br /> below the water table in an aquifer that is used or has the potential to be used for domestic use is <br /> prohibited. <br /> A request may be made with the state's Water Quality Control Commission for a variance for site <br /> specific groundwater standards. Unless a variance is granted or additional data is provided which <br /> demonstrates exceedance of ground water standards will not occur, the Division will maintain its <br /> unfavorable recommendation for the proposed coal ash pilot project. <br />
