Draft Environmental Impact Report Pinole‐Hercules Water Pollution Control Plant Improvement Project Prepared for: City of Pinole 2131 Pear Street Pinole, CA 94564 March 15, 2010 Draft Environmental Impact Report Pinole‐Hercules Water Pollution Control Plant Improvement Project Prepared for: City of Pinole 2131 Pear Street Pinole, CA 94564 Contact: Dean E. Allison, P.E. Director of Public Works/City Engineer (510) 724‐9010 Prepared by: AECOM 2022 J Street Sacramento, CA 95814 Contact: Wendy Copeland Project Manager (916) 414‐5800 March 15, 2010 09110101.01 03.15.10 NOTICE OF AVAILABILITY OF THE DRAFT ENVIRONMENTAL IMPACT REPORT AND PUBLIC MEETING ON THE PINOLE-HERCULES WATER POLLUTION CONTROL PLANT IMPROVEMENT PROJECT The City of Pinole has prepared a draft environmental impact report (EIR) for the Pinole-Hercules Water Pollution Control Plant (WPCP) Improvement Project in compliance with the California Environmental Quality Act (CEQA) (Public Resources Code Section 21000 et seq.) and the State CEQA Guidelines (14 California Code of Regulations Section 15000 et seq.). The WPCP treats water from the Cities of Pinole and Hercules. The overall project purpose is to bring the WPCP into compliance with the National Pollutant Discharge Elimination System (NPDES) permit issued by the Regional Water Quality Control Board. Description of the Project: The Pinole-Hercules WPCP Improvement Project involves two options: (1) construction of upgrades at the existing plant, relocation of the City of Pinole corporation yard, and construction of a new parallel force main to the Rodeo Sanitary District (RSD); or (2) treatment of City of Pinole flows only at the existing plant and upgrades to the WPCP facility. The project would include an increase in the Pinole-Hercules WPCP’s permitted wet-weather treatment capacity, but there would be no increase in the permitted dry-weather treatment capacity. Project Location: The WPCP is located along the shoreline of San Pablo Bay, at 11 Tennent Avenue, Pinole, California, within Contra Costa County. The proposed force main under Option 1 would exit the WPCP from Tennent Avenue and cross Pinole Creek; it would then parallel the creek for approximately 1,100 feet to the intersection with San Pablo Avenue. The force main would remain within San Pablo Avenue until entering the unincorporated community of Rodeo, where it would turn north onto Parker Avenue, east onto 2nd Avenue, north onto Railroad Avenue, and then east to return to San Pablo Avenue before entering the RSD. Project elements associated with Option 2 would occur entirely within the existing WPCP facility. Significant Environmental Impacts of the Project: Analysis of environmental impacts associated with the WPCP identified potentially significant impacts in the following issue areas: air quality and odors, climate change, cultural resources, fisheries and aquatic resources, geology and soils, hydrology and water quality, noise, and terrestrial biology. All impacts would be mitigated to a less-than-significant level except for cumulative construction- and operation-related air emissions, which is considered a significant and unavoidable impact of the project. Public Review Period: The draft EIR is available for review during a 45-day comment period that begins on March 15, 2010 and ends on April 28, 2010. A public hearing on the draft EIR will be held on April 7, 2010 at 6 pm at the Pinole City Hall. Copies of the draft EIR can be reviewed at the following locations: Pinole City Hall Hercules Library Pinole Library 2131 Pear Street 109 Civic Drive 2935 Pinole Valley Road Pinole, CA 94564 Hercules, CA 94547 Pinole, CA 94564 Written comments must be postmarked no later than April 28, 2010 and should be sent to the following address: Dean Allison City of Pinole Public Works Director 2131 Pear Street Pinole, CA 94564 (Email: [email protected]) TABLE OF CONTENTS Section Page EXECUTIVE SUMMARY ...............................................................................................................................
