k'q KLEINFELDER <br /> An employee owned company <br /> File No. 50890.E01 <br /> July 20, 2005 <br /> Mr. Carl Ryalls <br /> California Nuggets <br /> 23073 S. Frederick Road <br /> Ripon, California 95366 <br /> Via Facsimile 209.599-6320 and U.S. Mail <br /> RE: ADDENDUM LETTER, <br /> GROUNDWATER MONITORING WORKPLAN <br /> CALIFORNIA NUGGETS <br /> RIPON, CALIFORNIA <br /> Dear Mr. Ryalls, <br /> This addendum to the original letter prepared for the Baseline Groundwater Quality <br /> Assessment (Kleinfelder document 50890.E01/STOR358 dated April 29, 2005) is in <br /> response to the comments from the State of California Regional Water Quality Control <br /> Board (RWQCB) and their requirement to address those comments prior to <br /> commencing any work. The italicized comments made by the RWQCB are as re-stated <br /> below followed by a response. <br /> Please reconsider the well construction. Section 4.2 states that a 15-feet long well <br /> screen will be placed so that 10-feet of the screen extends below the water table. If <br /> floating phase liquids are not anticipated to exist at the site it may be beneficial to set <br /> the well screen slightly deeper to minimize the likelihood of the wells going dry later in <br /> the year when the regional water table may be lowered by groundwater pumping or <br /> seasonal fluctuation. <br /> Floating phase liquids are not anticipated at the site. In accordance with the RWQCB <br /> concern that the wells may be placed too high in the water table and dewater during <br /> seasonal periods of lower water table levels; we propose to install the monitoring wells <br /> an additional 5-feet to a total depth of 30-feet. The well screens will be 15-feet long <br /> and be installed between 15-feet and 30-feet below the ground surface. Groundwater <br /> is anticipated at approximately 15-feet below ground surface. The revised construction <br /> detail can be seen on the attached Revised Plate 3. <br /> The well construction described in Section 4.2 includes a 15-feet long screen; Plate 3 <br /> indicates the well screen will be 10-feet long. Please clarify the proposed well <br /> construction and revise Plate 3 as needed. <br /> As indicated in the text of the Workplan; the total well screen length will be 15-feet long. <br /> Attached to this addendum letter is a Revised Plate 3. <br /> 50890.EO1/ST05L236 Page I of <br /> 0 2005 Kleinfelder, Inc.
