I. Purpose and Scope <br /> This plan outlines the surface water sampling and analysis that will be conducted to monitor the water quality <br /> in Yule Creek and other surface water sampling locations associated with the October 2019 diesel fuel spill. <br /> That spill released approximately 5,500 gallons of diesel to road fill material near Portal 4 as a result of an <br /> accidental overfill of a generator day tank. <br /> On October 16, 2019 Colorado Stone Quarries (CSQ) reported to the Department of Reclamation and Mining <br /> Safety(DBMS)and Colorado Department of Public Health and Environment(CDPHE)that a diesel fuel release <br /> occurred on October 11, 2019 from an above ground storage tank which impacted the underlying fill material <br /> below the tank and an associated generator. CSQ personnel discovered diesel fuel daylighting within a sump, <br /> approximately 1,200 feet downgradient from the release point. CDPHE issued a release spill tracking # 2019- <br /> 0587 and noted that the DRMS will be the lead agency on monitoring the remediation. <br /> HRL Compliance Solutions Inc. (HRL) was contracted on October 23, 2019 to perform an initial onsite <br /> inspection and evaluate the impacted area to provide support for initial clean-up in conjunction with <br /> remediation, sampling, waste management and monitoring support. <br /> The following information provides details of the surface water sampling on Yule Creek, outlining the <br /> frequency,sample procedures,analysis and contingency plans should detections above the regulatory threshold <br /> be observed. It should be noted that changes in the project and scope may directly affect the specifics of this <br /> surface water sampling& monitoring plan. <br /> II. Plan Applicability <br /> This plan is applicable to the surface water monitoring on Yule Creek and any other associated surface water <br /> sampling and/or monitoring that may be incorporated after the date of this plan. This plan is intended to ensure <br /> that all surface water samples collected as of January 2020 are sampled in accordance with this plan and <br /> documented properly. For specifics regarding groundwater sampling and monitoring, please refer to CSQ's <br /> "Groundwater Sampling&Monitoring Plan." <br /> Ongoing surface water sampling of Yule Creek will be conducted at previously established sample locations <br /> along Yule Creek to monitor for the presence of hydrocarbons associated with the October 2019 diesel release. <br /> Sample locations will vary during the winter months as access is limited or entirely inaccessible due to <br /> snowpack. <br /> III. Sampling Locations <br /> Upon discovery of the release, the following surface water sample locations have been established on Yule. <br /> Creek; <br /> A. Upgradient(UG 1) <br /> A sample point has been established upgradient from the point of release to serve as a background sample <br /> for comparison to current water quality conditions in Yule Creek. <br /> B. Cross Gradient(CG 1) <br /> A sample point immediately cross gradient from where the release occurred has been established to <br /> monitor if any cross-gradient movement of hydrocarbon impacts are occurring. <br /> l <br />
