Irvine Ranch Water District • IRWD Services IRWD Services • Potable and recycled water, sewage collection and treatment urban runoff and treatment, urban runoff treatment • Service Area • 115,531 acres • Wastewater Treatment • Michelson Water Recycling Michelson Water Recycling Plant (MWRP) • Currently being expanded • Los Alisos Water Recycling Plant (LAWRP) 4
Project Location Project to be constructed on disturbed vacant land within the current boundary of the MWRP 5
6 Wastewater Treatment Process (Current)
7 Wastewater Treatment Process (Proposed Project)
Project Objectives and Benefits •Allow IRWD to make efficient and sustainable use of its own Allow IRWD to make efficient and sustainable use of its own renewable resources •To make beneficial use of biosolids and biogases produced during the treatment process d i th t t t •Provide for greater control of residual (solids) management at reduced costs reduced costs •Minimize environmental impacts associated with solids management •Construct a biosolids handling and energy recovery facility that adequately provides for IRWD ’ s future biosolids handling needs 8
Project Description •IRWD to construct facilities at MWRP for: •Biosolids processing Biosolids processing •Biogas management & energy recovery •Odor Control System Odor Control System •IRWD would no longer export solids to Orange County Sanitation District (OCSD) •Project would dry solids from IRWD’s LAWRP •Delivered by truck 9

Summary of Impacts and Mitigation • General Conclusions: • General Conclusions: •The project would have no significant unavoidable impacts. id bl i t •All impacts can be mitigated. •None of the Alternatives are environmentally superior to the Project. environmentally superior to the Project. 14
Summary of Impacts and Mitigation Impact Key Issues Mitigation Summary Category Aesthetics New structures would be contrasting • Selecting paint color schemes that blend features visible from public vantage points. with color palette of surrounding landscape New Nighttime security lighting could affect • External lighting to be shielded and neighboring land uses neighboring land uses directed downward to limit light spill offsite directed downward to limit light spill offsite. Air Quality Construction and operation would not emit N/A pollutants in excess of federal or state air quality standards. Odor Control System would prevent the release of objectionable odors. Biological No direct impacts to biological resources • Measures to detect and avoid impacts to Resources due to existing disturbance at project site. special ‐ status bird species in adjacent natural habitat during nesting season. Potential indirect impacts to biological resources in adjacent natural habitat during • Measures to restore habitat and vegetation construction affected during construction. Cultural Cultural Potential impacts to cultural resources due Potential impacts to cultural resources due • Cultural resource monitoring during • Cultural resource monitoring during Resources to ground disturbance during construction construction 15
Summary of Impacts and Mitigation Impact Key Issues Mitigation Summary Category Geology, Soils & Project design incorporates features identified in N/A Mineral geotechnical study to mitigate potential effects of land Resources subsidence. Project incorporates engineering design criteria required by California Building Code to mitigate potential effects of seismic activity Greenhouse Gas Net GHG emissions (construction and operation) would N/A Emissions not exceed thresholds. Project supports plans, policies and regulations to reduce GHG emissions through use of renewable energy resources. Local beneficial use of biosolids reduces GHG emissions L l b fi i l f bi lid d GHG i i associated with trucking biosolids out of region/state. Hazards & Accidental release of hazardous materials during • Contractor to implement Best Hazardous project construction could occur. Management Practices (BMPs) to Materials Materials prevent accidental releases of prevent accidental releases of Hazards associated with chemical use and biogas hazardous materials handling minimized with project design features: secondary containment, leak detection monitors, 16 operational safeguards, and equipment redundancy.
Summary of Impacts and Mitigation Impact Key Issues Mitigation Summary Category Hydrology & Water Accidental chemical spills could wash • Updating existing Storm Water Pollution Quality offsite and pollute surface waters or Prevention Plan to include BMPs to avoid groundwater accidental spills. The MWRP flood wall protects the The MWRP flood wall protects the project from a 200 ‐ year flood. Land Use, Planning Project facilities would be consistent N/A & Recreation with the City of Irvine Zoning Code but would require a Conditional Use q Permit. Noise Construction activities will generate • Compliance with City of Irvine Noise Ordinance noise for construction (7am to 7pm M ‐ F, 9am to 6pm Sat) or as permitted by the city New permanent noise ‐ generating • Noise control techniques applied to construction equipment will be designed to adhere equipment to City of Irvine Noise Ordinances. • Establishment of a noise disturbance coordinator to respond to noise complaints • Post construction noise survey to ensure that Post construction noise survey to ensure that operation of new equipment is in compliance with City of Irvine Noise Ordinance at the property boundary. 17
Summary of Impacts and Mitigation Impact Key Issues Mitigation Summary Category Utilities & Energy Adequate landfill capacity to accommodate N/A construction waste and provide backup disposal outlet for biosolids. Energy recovery systems would offset project electricity and natural gas demands (beneficial use of biogas) Project replaces energy consumed at OCSD for solids treatment. Transportation & Operational truck trips would not affect N/A Traffic traffic or circulation system performance on local or regional roadways. L Local reuse of biosolids would reduce traffic l f bi lid ld d ffi on state freeways associated with hauling and disposal of biosolids out of region/state 18
