Description of Notifications and Permits <br /> . . <br /> PartyNotification Notification Details <br /> Regional Board City/West Yost Notify at least five(5)working days before commencing site work. <br /> Executive Officer <br /> Prior to well construction, obtain a drilling permit, and mark the <br /> approved drilling location prior to mobilization. <br /> San Joaquin Notify 24 hours in advance of completing the well seal (See <br /> County EHD Drilling contractor Section 4.2.2). <br /> If a borehole is drilled but not used for the ultimate monitoring <br /> well, notify 24 hours in advance of borehole abandonment. (See <br /> Section 4.2.3). <br /> Notify at least 48 hours prior to drilling to allow for the location of <br /> USA North(a) City/West Yost any known or identified underground utilities or other hazards to <br /> be painted on the ground surface. <br /> (a) Underground Service Alert of Northern/Central California and Nevada <br /> 4.2 Monitoring Well Installation <br /> The proposed monitoring well will be installed using a hollow-stem auger with an 8-inch inside <br /> diameter to allow a minimum sand pack thickness of two inches between the well and the casing <br /> wall. The borehole will be drilled to a depth that will ensure the setting of the well screen at the <br /> appropriate interval while providing adequate space to accommodate a bottom well cap and <br /> approximately one foot of sand pack below the screen. The proposed well, WSM-2R, is expected <br /> to be drilled to approximately the 30 feet below grade (Figure 4-1). The actual well depth, and <br /> the depth intervals for the placement of perforated intervals, filter pack and annular seals will be <br /> determined based on the hydrogeologic conditions encountered during drilling. <br /> 4.2.1 Borehole Logging <br /> An experienced field geologist (or engineer) supervised by a California Professional Geologist <br /> will lead all field activities, including soil logging and well installation. The field geologist will <br /> record observations on boring logs in accordance with the Unified Soil Classification System <br /> (ASTM D2488). A boring log/well construction diagram is included in Appendix A. The <br /> information recorded will include soil classification, density or consistency, color, soil name, <br /> moisture content, and particle size distribution. The boring log will also contain observations <br /> related to drilling activities, including methods, equipment, drilling rates, well construction, and <br /> any unusual conditions encountered during drilling. A California Professional Geologist will <br /> review and approve the soil boring log. <br /> WEST YOST ASSOCIATES 5 City of Lodi <br /> September 2014 Monitoring Well Installation Work Plan <br /> w\c\213\06-14-31\wp\WP\083014_1 RWP <br />
