Section 8 <br />well would be a nested monitoring well and would be drilled by direct mud rotary <br />drilling equipment and would occur 24 hours a day over a two week period and <br />12 hours a day over another two week period. After well construction is <br />completed the parking direct parking area would be resurfaced with decomposed <br />granite. Additionally, as part of site improvements at Heritage Museum, an <br />existing irrigation system to the demonstrate garden would be replaced and <br />interpretive education kiosks would be installed. <br />8.3 Long Term Maintenance <br />Injection Wells <br />The injection wells are routinely redeveloped every two to five years to remove <br />accumulated sediments and microbiological build -up within the well casings to <br />restore the well capacity to operate at their maximum injection capacity. As part <br />of the redevelopment the injection well would be back washed. The discharging <br />of the well water associated with redevelopment activities will be conducted in <br />accordance with NPDES Permit requirements. <br />Monitoring Wells <br />Every two years OCW D assesses the condition of monitoring wells to determine <br />if they need redevelopment. The redevelopment activities would be similar to an <br />injection well. <br />8.4 Construction Phasing Plan <br />The Proposed Project is estimated to take 14 months of active construction and <br />is broken into 8 phases. Constructions are expected to start of early 2017 and <br />conclude in 2019. <br />8.5 Federal Endangered Species Act (ESA), Section 7 <br />Does the project involve any direct effects from construction activities, or <br />indlirect, effects such as growth inducement that may affect federally listed <br />threatened or endangered species or their critical habitat that are known, or <br />have a potential, to occur on -site, in the surrounding area, or in the service <br />area? <br />9 No. Discuss why the Project will not impact any federally listed special status <br />species: <br />The following analysis is based on the Biological Assessment that was prepared <br />for the Mid Basin Centennial Park Injection Well Project by the l'OCWD Natural <br />Resources Department in June of 2015. The Biological, Assessment with <br />database searches is presented in Appendix C. <br />Mid Basin Centennial Park In, 11Project Final EIR 8 -4 <br />
