We do allow the first explosive charge to be <br /> placed 20 feet below grade to full length of the casing for these destructions, as Tylor notes below. The charges are <br /> exploded after the well has been filled with neat cement from bottom to surface. <br /> Thank you for the clarification, <br /> Adrienne <br /> Adrienne Ellsaesser, REH5 <br /> Program Coordinator <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton , CA 95205 <br /> Ph (209)468-0343 <br /> Fax (209)468-0341 <br /> aellsaesser@sicehd.com <br /> From: tylor mcmillan [mailto:mcmillans521@yahoo.com] <br /> Sent: Monday, October 07, 2013 1:22 PM <br /> To: Sobieraj, Justin <br /> Cc: Adrienne Ellsaesser[EH]; Amber.Nickens@arcadis-us.com; bwaite@chevron.com; Nuel Henderson [EH]; Lisa Medina <br /> [EH] <br /> Subject: Re: 3978 S Hwy 99 Stockton, CA - Status remaining well destructions (309075) <br /> Everyone, <br /> Welenco has been blasting wells below the existing sanitary seals for years now. <br /> We have two reasons for this: Setting off any type of explosive charge inside of an existing sanitary <br /> seal only accomplishes two things. It cracks or breaks the existing.seal and it increases the potential <br /> for over pressure at the surface which causes fly material. <br /> i <br />
