Mike Infurna [EH] From: Mike Infurna [EH] Sent: Wednesday, July 27, 2005 1:48 PM To: 'jlane@groundzeroanalysis.com' Cc: Margaret Lagorio [EH] Subject: RE: Berberian Property, 26239 Miller Avenue, Escalon, CA I've checked with the boss to see if after ALL of this site's/RPs failure to check with anyone before doing most of the work, we will issue a letter of no further investigation needed. In the report of findings (sludge sample results and your RG sign off) there is to be a signed affadavit from Mr. Van Spronson stating and responding to the following concerns; 1- The removal and current disposition of the (posted) "unsafe" dwelling/moble home, 2- a statement that he dug up potentially contaminated soils and disposed of them without notification to the regulatory agency, 3- a statement as to the status (chemical/biological)and disposition of the actual concrete septic tank, 4- a statement that he/someone removed dried septic tank (uncharacterized) sludge from the site, hauled it to another county (under what type of manifest?) without regulatory approval and then returned the (SAME?) 'contents to the place of origin and, 5- the status of the drinking water well previously used at this moble home. If the affadavit is adequate and the report of findings is a valid representation of the work and site status (supports no further action/no further investigation needed, After EHD inspection and review fees are paid, EHD will generate the 'closure' letter removing this site from the local, state, and Federal UIC database. . If this works for you and your client, please call me for the appointment to sample the sludge. -----Original Message----- From: John Lane [mailto:jlane@groundzeroanalysis.com] Sent: Tuesday, July 26, 2005 9:54 AM To: Mike Infurna [EH] Subject: Berberian Property, 26239 Miller Avenue, Escalon, CA Mike. As we discussed, I am writing to summarize activities related to the evaporation of the liquid contents/rinsate from the septic tank formerly located at the subject Site. As you know, Ground Zero presented a workplan to evaporate the liquid pursuant to an exemption from the Air Board (<2 lbs VOCs per day) , then sample the dried sludge to determine if residual contamination remained. Based upon a sample collected from the contents of the septic tank, the liquid was not a hazardous waste and contained less than 0.1 lbs of VOCs. Mr. Van Spronson notified Ground Zero on June 17, 2005 that the liquid had been evaporated and that the sludge was sufficiently dried to collect samples. When Ground Zero indicated to Mr. Van Spronson that a site inspection was necessary to confirm this, Ground Zero was directed to another property on Ladd Road in north Modesto. Ground Zero was unaware that the contents of the septic tank had been transported off- site for evaporation. I inspected the desiccated sludge, which had been placed upon plastic sheeting. Ground Zero prepared a workplan 1 CONFIDENTIAL
