These regulations govern <br /> the investigation and mitigation activities at leaking underground storage tank sites. To obtain a copy, <br /> please contact the SWRCB at(916)657-2390. Remedial Action Completion certification occurs only <br /> after PHS/EHD has determined that no further site investigation or remedial action is required. <br /> All work and reports which require geological or engineering evaluations must be performed under the <br /> direction of an appropriately California registered or certified professional. <br /> As a follow up to our May 20, 1997 meeting, PHS/EHD provides the following directive to all responsible <br /> parties at the above listed site based upon the following information. <br /> Analytical data from overexcavation and product line samples obtained August 15, 1996 at the site listed <br /> above confirm the presence of petroleum hydrocarbons in soil as a result of an unauthorized release. <br /> Samples were obtained during the limited overexcavation at a depth of approximately 25 feet below grade <br /> surface and given the estimated groundwater elevation of approximately 30 feet below grade surface a <br /> groundwater investigation is required. <br /> In accorrdance with corrective action regulation PHS/EHD directs you as responsible party to submit a <br /> comprehensive workplan which when implemented will fully define the lateral and vertical extent of <br /> contamination in both soil and groundwater. This workplan shall be submitted to PHS/EHD for review <br /> no later than July 21, 1997. <br /> If you have any questions or there are any corrections in the responsible party information, contact Ronald <br /> Rowe at(209)468-0342. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> JANOJA kpw2 <br /> Ronald Rowe, Senior REHS Margaret L�REHS <br /> LOP/Site Mitigation Unit IV Supervisor <br /> > <br /> RR:lb <br /> + c: SWRCB, Underground Storage Tank Section-Lori Casias <br /> c: RWQCB, Central Valley Region-Elizabeth Thayer <br /> (SITELET REV 02/20/97) <br /> A Division of San Joaquin County Health Care Services <br />
