At the time the workplan was submitted, an accompanying letter requesting a <br /> priority review by those agencies was included. A telephone conversation on March 30. 1989 <br /> from the California Regional Water Quality Control Board verbally approved our workplan, <br /> and it was indicated that a letter of review from the RWQCB was being sent to the San <br /> Joaquin Local Health District expressing that approval. <br /> A telephone call was placed by Dames & Moore to the San Joaquin Local Health District <br /> on May 3, 1989 to determine the progress of the review of our workplan necessary to secure <br /> permits to proceed with the installation of the monitoring wells. Messages were left with a <br /> Cynthia Wagner of the San Joaquin Local Health District, and a call was returned to Dames & <br /> Moore on May 10, 1989. Ms. Wagner was appraised of desire to obtain the priority two-week <br /> review so work at the subject property could commence in accordance with the workplan. Ms. <br /> Wagner indicated Diane Hinson of the SJLHD had reviewed the workplan and made comments <br /> regarding our technical approach. Those comments were relayed to Dames & Moore as follows: <br /> 1. It was the opinion of the SJLHD that the monitoring wells needed to be located closer <br /> to the previous tank cluster area, otherwise the SJLHD would consider the area interior <br /> to the well boundaries as needing further assessment; <br /> 2. Chemical analysis of samples obtained should include analysis for low-boiling point <br /> hydrocarbons; <br /> 3. To verify any abandoned wells on-site were abandoned in accordance with local <br /> regulatory requirements; and <br /> OFFICES WORLDWIDE <br />
