1.0 Introduction. <br />This Waste Management Contingency Plan ("WMCP") has been prepared on behalf of <br />Fruita Mazketing & Management, Inc. ("FMM") by Mesa Environmental Inc., ("MEI"), <br />to guide waste management practices during the proposed sand and gravel mining <br />activities on an approximately 70 acre leased azea of FMM's facility at 1493, Highway 6 <br />& 50, two mile west of Fruita, Colorado. Gravel Mining is expected to commence in <br />winter 2003/2004 in the area known as Evaporation Pond No. 9 (see figure 1) and <br />continue for several yeazs at the site. <br />The facility, including the area to be mined, is currently subject to Colorado Deparhnent <br />of Public Health and Environment, Hazazdous Materials and Waste Management <br />Division ("Division") Compliance Order No. 98-06-05-01 ("Order'. In accordance with <br />the Order, FMM is required to chazacterize soil and groundwater contamination at the <br />facility. A "Soil Characterization Plan ("SCP") (March 29, 200]) was submitted and <br />approved with modifications by the Division on May 7, 2001. The focus of the SCP was <br />on Area A, the azea within the gravel mining lease boundary as depicted on the Site Plan <br />(see figure 1). Area A was further subdivided into three Subareas, (1-3) (see figure 2). <br />Subarea 3 includes Evaporation Pond No. 9 and the land to the north, and was expedited <br />for characterization to allow mining to begin in this area. Soil and groundwater sampling <br />was conducted in Subarea 3 in the summer of 2001, and the results are included in the <br />"Soil Chazacterization Data for Evaporation Pond No. 9 (October 29, 2001) and <br />associated analytical reports. <br />Gravel Mining will be conducted in Evaporation Pond No. 9 for the first few yeazs, but it <br />is planned to eventually progress westward to include the area of Oxidation Ponds No 1-3 <br />(see figure 2). However, no mining (or any other related activity} will occur in the area of <br />these land based RCRA units (Oxidation Ponds 1-3 and associated ditches north of <br />Oxidation Pond No. 1) until they are certified clean-closed under the Final Closure Plan <br />for Waste Pile No 4. In addition, no areas other than Subareas 1 and 3 will be mined until <br />characterized in accordance with the SCP and approved by the Division. <br />Known and potential contaminants include a variety of hydrocarbons and other organic <br />compounds (e.g. benzene, toluene, ethylbenzene, xylenes [BTEX], methyl tertiary butyl <br />ether (MTBE], total petroleum hydrocabons [TPH], semi volatile organic compounds <br />[SVOC's] and RCRA metals (e.g. chromium and lead). Since environmental media (soil <br />and groundwater) contaminated with these compounds may be encountered in the gravel <br />lease area during mining activities, the Division has requested that FMM prepare this <br />WMCP. <br />This WMCP summarizes the methods that will be used to recognize, chazacterize, handle, <br />store and dispose of contaminated environmental media, solid wastes (scrap metals, old <br />tires, scrap lumber), asbestos containing building materials (ACBM) or pipe insulation, or <br />hazardous wastes encountered in the gravel mining azea. All waste management practices <br />will be in accordance with the Division's requirements. <br /> <br />
