Angelica Sandoval Marin [EH] From: Scott <SBittinger@stratusinc.net> Sent: Monday, November 03, 2014 9:11 AM To: Angelica Sandoval Marin [EH] Subject: 0 2057 South EI Dorado Street, Stockton 1 V, C li, I am writing this e-mail in order to request an extension for the activities requested by San Joaquin County Health Department, in a letter dated October 29, 2014. Specifically, an extension for submitting a Site Conceptual Model, Corrective Action Plan, and Work Plan for Additional Site Assessment is necessary. At this time, there is inadequate funding available from the UST Cleanup Fund for the 2014/2015 fiscal year to complete these tasks. Stratus has prepared and submitted a Budget Change Order Request to the UST Cleanup Fund already, however, to date, no response has been received. It should be noted that in order to properly perform additional environmental assessment activities, Stratus would need to perform environmental drilling work at 2070 South EI Dorado Street, which is immediately east(downgradient) of the site. It should be noted that the 2070 South EI Dorado Street property formerly operated as a service station, and based on information provided by Harlin Knoll a few years back, there appears to be underground storage tanks still in the ground at this facility, but never removed. It is my understanding that performing environmental assessment work east of the site was informally delayed due to the recalcitrant issues by the owner of the propOwty last of the site-related tQ long-overdue underground tank removal requirements. In regards to the Corrective Action Plan requirements, Stratus is currently implementing a 'Work Plan for Groufidwater Remediation' at the site, which was approved by San Joaquin County Health Department in September 2013. Although this document was not titled a 'Corrective Action Plan', it is essentially the same scope of work. Vadose zone remediation by vapor extraction has already been completed at the site. Groundwater remediation is now being completed in the upper water bearing zone using the September 2013 scope of work. Unfortunately, due to budget constraints imposed by the UST Cleanup Fund, we are unable at this time to implement all of the activities necessary for the site. Stratus will provide periodic updates to San Joaquin County regarding the status of work activities. For the time being, Stratus is requesting a nine month extension for submittal of the CAP, SCM, and Work Plan, with a new deadline of late July or early August 2015. If additional funds become available, some of the requested tasks could potentially be completed before this time. Thank you. Scott Bittinger Ctratiic FnvirnnmPntal Inc_
