Kleinfelder is committed to providing quality service to our clients, commensurate with their wants, needs, and desired level of risk. If a portion of this proposal does not meet the needs of Balfour Beatty Infrastructure, Inc., or if those needs have changed, Kleinfelder will consider appropriate modifications, subject to the standards of care to which we adhere as professionals. Modifications such as changes in scope, methodology, scheduling, and contract terms and conditions may result in changes to the risks assumed by you our client, as well as adjustments to our fees. We look forward to the opportunity to serve you. BACKGROUND Mr. Travis Price of Balfour Beatty Infrastructure, Inc., contacted Kleinfelder to provide this proposal to properly abandon seven piezometers in accordance with Sacramento and San Joaquin County Well Standards. Three of the piezometers (MP-6, 10, and 11) are located in Sacramento County at the Clay Station Pumping Plant Site. Four of the piezometers are located in San Joaquin County, three (LH-3, 6, and 9) of which are located at the Comanche Site and one (MQ-7A) which is located at the Pipeline No.2 Flow Splitting Facility Site. The borings for the piezometers range in depth from approximately 26 to 60 feet below the ground surface (bgs). We understand that the piezometers were installed as part of a geotechnical investigation of the structural facilities associated with the Folsom South Canal Connection operated by the EBMUD. The following table details the construction of the piezometers and is based upon the Plates, provided by the client and originally included in a Piezometer Installation Report. According to the piezometer construction plates and information obtained from the EBMUD Materials Engineering Section, with the exception of MP-11 and a portion of MP-10, the piezometers were installed in eight-inch diameter borings. Piezometers MP- 11 and MP-10 (from 35 to 60 feet bgs) were installed in five-inch diameter borings . 02001 PROP.ENV/ST07P230/FB:ly Page 1 of 5 ©2007 Kleinfelder September 11, 2007
