Work Plan Project Description (general) This project consists of the planned construction of one dual -completion groundwater monitoring well and one quodruple-completion groundwater monitoring well in the Eastern San Joaquin Subbasin. The proposed wells will aid the development and implementation of the GSP to fill critical data gaps near potential Groundwater Dependent Ecosystems (GDEs), streams, subbasin interaction, and areas outside of existing monitoring networks. This will enhance the hydrogeologic conceptual model (HCM) by helping to refine the bottom of the freshwater layer and better understand localized hard rock or clay/silts of the Valley Springs/Ione. The monitoring wells will also be used in the monitoring of minimum thresholds for lower groundwater levels, and groundwater/surface water interaction. The projected monitoring well details are summarized in the following table. See attached well diagrams for construction details. Project Name: DWR Region Office: GSA Name: Property Owner Name: NSJWCD-01 North Central North San Joaquin County of San Joaquin (Monitoring Well B) Water Conservation District Project Location: Planned Exploration Planned Well Screen Well Casing Type and 38234742, -121.225805 Depth: Target Depth Intervals: Diameter: 1,650 feet 160'-190'; 330'-360'; 2.5 -inch -diameter, SCH 550'-590'; 740'-780'; 80, PVC well casing 1,200'-1,250'; 1,600'- with mill -slotted screens 1,640' Other Services: Geophysics, well development, groundwater sampling Coordination of project activities will be managed by DWR staff from the above listed Region Office. 1— CEQA and Site Clearances DWR will assess the proposed well location prior to commencing any construction. DWR's site evaluation may include a review of information provided by the GSA, independent on-site review, or both. If DWR determines that an on-site review is required, the GSA shall make the site accessible to DWR staff or contractors. If DWR determines that no exceptions exist to the project being exempt from the California Environmental Quality Act, DWR will file a Notice of Exemption (NOE) with the Office of Planning and Research. If DWR determines that filing a NOE is not appropriate, the GSA may propose another well location, however DWR will not undertake any construction unless DWR determines that the site provided is eligible for a NOE. DWR will contact Underground Service Alert North (811) and conduct utility locating, as needed, to ensure safe execution of the project's construction. 2 — Permitting Site Entry The project is to be located on property owned by the County of San Joaquin and the GSA will contact and negotiate with the property owner to obtain a land use agreement of enough size and accessibility to construct, operate, and maintain groundwater monitoring equipment as described herein for the useful life of the project. Other A well drilling and construction permit will be obtained by the GSA. DWR will not make reimbursements for any permit fees.
