(Stratus) has prepared this Work Plan for Offsite Monitoring <br />Well Installation (Work Plan), on behalf of the Knowles Family Trust, for the Knowles <br />Property located at 1120 West Hammer Lane, Stockton, California (the site, see Figure <br />1). Petroleum hydrocarbon impact to the subsurface has previously been documented at <br />the subject property, and the California Regional Water Quality Control Board <br />(RWQCB) currently regulates an environmental case on the property. Mr. Knowles was <br />recently accepted into the Underground Storage Tank (UST) Cleanup Fund's Expedited <br />Claim Account Program (ECAP), which is intended to develop a list of tasks needed to <br />manage the site's environmental case towards eventual closure. During a Joint Execution <br />Team (JET) meeting, the RWQCB and the UST Cleanup Fund requested that an offsite <br />groundwater monitoring well be installed north-northeast of the site. The purpose of the <br />well is to further delineate the extent of petroleum hydrocarbon and fuel additive impact <br />to shallow water, and provide water quality information between the site and a <br />neighborhood to the north where numerous domestic water supply wells have been <br />identified. Details associated with the proposed installation of the well (MW-13) are <br />described in the following subsections of this Work Plan. <br />SCOPE OF WORK <br />The objective of the proposed scope of work is to further assess impact to groundwater <br />north-northeast of the site. To accomplish this objective, Stratus is proposing the <br />following work activities. <br />Drill and install one (1) groundwater monitoring well (MW-13) offsite using <br />hollow stem augers. <br />K:\Knowles-Hammer LaneWork Plans\knowles-hammer-offsite-well-workplan.doc
