The Work Plan proposes to dig six trenches <br /> two to three feet deep around aboveground tank (AGT) No. 3302 to delineate the extent of <br /> separate phase hydrocarbons (SPH), to monitor wells PS/P-10, PS/P-11, and PS/P-12 to verify <br /> whether recent releases have affected the groundwater downgradient of AGT 1503, and to remove <br /> SPH in ST/MW-1 by hand bailing weekly. <br /> The Work Plan does not discuss whether ST Services will dig step-out test pits in the event that <br /> SPH is encountered in a test pit. Board staff concurs with the Work Plan provided that ST <br /> Services digs step-out test pits where necessary to delineate SPH in soil and groundwater. By <br /> 9 May 2003, please submit an investigation report detailing field activities including the <br /> monitoring well data and results of weekly hand bailing of ST/MW-1.
