Page 2 of 6 Apologies if my field dates were interpreted as a hard schedule. Definitely understand that the dates are dependent the on EHD availability to the project, and on getting you the application in the first place. Those dates were provisional with the understanding that the field schedule will be set after permitting was complete. I should be able to get the application sent out by Wednesday. Thanks Mike. Please call or email if you have any questions. -Jamey Jamey Peterson I Staff Geologist I jamey.peterson@arcadis-us.com ARCADIS U.S..

From: Mike Infurna [EH] [mailto:MInfurna@sjcehd.com] Sent: Friday, April 02, 2010 1:57 PM To: Peterson, Jamey Subject: RE: mcdonald island subsurface investigation - sjc permit application Jamey, sounds like there are NO structures on this site, hence the 0000/lack of an address. Get me the Assessor's Parcel Number (APN). I can verify info on my County link to the Assessor. If there IS an address, I'll let you know and you should use it with ALL correspondence related with this site. Backfill: bentonite is ONE of four types of materials allowed for backfill. Native fill is only allowed at NON contaminated sites, sites doing Geotechnical borings at NON contaminated sites, or for the last 3 feet bgs in ag fields/unimproved lots for contaminated site borings, if needed for site specific surface conditions. For your concerns and at this particular site, plan on NOT using drill cuttings/native fill. see below for acceptable alternatives. Subsurface investigations at suspected/ historically potential, or known contaminatied sites are required to backfill holes with one of the materials listed in Section 4.7.3. Native soils/drill cuttings are not allowed at contaminated, known or suspected, sites. MOST of the methods and things you plan on doing with respect to our Ordinance at this site can be found in Section 13. Although mostly for monitoring wells, this section contains soil boring info too, particularly sections 13.17.7, & -8, -9, -14, & -15.. Although 'approved' sealing materials are listed in Section 4.7.3., keep most of your focus on section 13. MFR: 'landowner' section at top: ALL parcels are owned by someone/some entity. List the property owner as noted on Grant Deeds or some legal docs for this parcel. GEt me the APN and I will verify with the currently listed owner as noted by the County Assessor. 'business' or 'facility' section: if there is a PG&E gas well on this property, than YES...list PG&E in this section. Lots of farmers LEASE their property to PG&E for deep gas well/storage. if so, then YES, this is a PG&E business. Farmer "BROWN's" infor will be above in the 'landowner' section. IF NOTHING, but dirt (no gas wells, pump house, 4/6/2010
