The SJCEHD <br /> permit and fees will be submitted by Tuesday, October 23, 2007, and yes, you have the <br /> correct billing address for ENSR. I have also attached the current access agreement from <br /> the property owner. <br /> In the event that the acceptance/approval letter for the addendum is not received in time <br /> from the CVWB to process the permit, ENSR will provide you with an alternate drilling <br /> date. <br /> I will be out of the office next week, so please notify Eric Siegel if there is a problem <br /> with the paperwork. Thank you for your assistance. <br /> Jennifer <br /> From: Mike Infurna [EH] [mailto:MInfurna@sjcehd.com] <br /> Sent: Friday, October 19, 2007 2 :08 PM <br /> To: Johnston, Jennifer <br /> Cc: Siegel, Eric; jbarton@waterboards.ca.gov <br /> Subject: RE: scheduled: replacement well (MW-15R) for 5606/5400 Pacific Avenue, Stockton <br /> I have received the work plan on September 10. Can you tell me if you plan on changing the <br /> size of the augers in the addendum? My experience has shown that trying to install a 2 .25 <br /> inch OD PVC casing and adding sand and adding bentonite inside of a 3 .24 inch ID of the <br /> augers to be very difficult to complete without bridging either the sand or the bentonite. <br /> If the bridging can not be removed, the well can not be completed. Additionally, the <br /> SJCEHD Well Standards require NLT a two inch annulus of grout around the casing (between <br /> the casing and the <br /> borehole) after the augers are removed. I will be onsite to verify this requirement and <br /> the well can not be grouted if the grout annulus is less than 2 inches. <br /> Unfortunately I can not accept/confirm an appointment to drill until the permit has been <br /> issued. I will reserve the morning for this activity with the understanding that all of <br /> the required submittals are at the SJCEHD with enough time for me to process. At a <br /> minimum, the SJCEHD requires two working days notice for appointments for field <br /> inspections. <br /> As a precaution, I recommend you check with your drilling contractor for a PLAN B date <br /> just in case you don't provide me with enough time to meet your schedule. Next week is a <br /> very busy field schedule for me and I'll be out of the office most of the time. If you <br /> wait until the last minute to get me the correct submittals, there is a significant chance <br /> the permit will not be issued in time to meet your date. I strongly recommend you get me <br /> all the following NLT Tuesday, Oct 23. <br /> At a minimum, I will need: <br /> -the revised/addended work plan, <br /> -the lead agency approval letter, <br /> -a SJCEHD permit application (two-paged) , -an $89 fee submittal and -proof (access <br /> agreement) from the current land owner that you/we are allowed on the property to do this <br /> job. <br /> Our records indicate that ENSR is listed as the entity to receive SJCEHD billing for work <br /> associated with this site. Please verify that Robert L'Heureux, 10641 Old Placerville Rd, <br /> Suit 170, Sacramento, 95827 is still the correct contact name and address to receive the <br /> billing. If not ENSR, then additional forms and fees will be required before the permit <br /> application can be processed. <br /> attached for your convienence is the SJCEHD webpage for the 2-paged permit application you <br /> will need to complete and return. Please note that if the C-57 driller does not sign page <br /> 2 <br />
