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

d i th t t t during the treatment process

• 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

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

Summary of Impacts and Mitigation

Impact Category Key Issues Mitigation Summary

Aesthetics New structures would be contrasting features visible from public vantage points. New Nighttime security lighting could affect neighboring land uses

• Selecting paint color schemes that blend

with color palette of surrounding landscape

• External lighting to be shielded and

directed downward to limit light spill offsite neighboring land uses directed downward to limit light spill offsite. Air Quality Construction and operation would not emit pollutants in excess of federal or state air quality standards. N/A Odor Control System would prevent the release of objectionable odors. Biological Resources No direct impacts to biological resources due to existing disturbance at project site.

• Measures to detect and avoid impacts to

special‐status bird species in adjacent Potential indirect impacts to biological resources in adjacent natural habitat during construction natural habitat during nesting season.

• Measures to restore habitat and vegetation

affected during construction. Cultural Potential impacts to cultural resources due

Summary of Impacts and Mitigation

Impact Category Key Issues Mitigation Summary

Geology, Soils & Mineral Resources Project design incorporates features identified in geotechnical study to mitigate potential effects of land subsidence. Project incorporates engineering design criteria N/A required by California Building Code to mitigate potential effects of seismic activity Greenhouse Gas Emissions Net GHG emissions (construction and operation) would not exceed thresholds. N/A Project supports plans, policies and regulations to reduce GHG emissions through use of renewable energy resources. L l b fi i l f bi lid d GHG i i Local beneficial use of biosolids reduces GHG emissions associated with trucking biosolids out of region/state. Hazards & Hazardous Materials Accidental release of hazardous materials during project construction could occur.

Prevention Plan to include BMPs to avoid accidental spills. The MWRP flood wall protects the project from a 200‐year flood. Land Use, Planning & Recreation Project facilities would be consistent with the City of Irvine Zoning Code but would require a Conditional Use N/A q Permit. Noise Construction activities will generate noise

Utilities & Energy Adequate landfill capacity to accommodate construction waste and provide backup disposal outlet for biosolids. Energy recovery systems would offset N/A project electricity and natural gas demands (beneficial use of biogas) Project replaces energy consumed at OCSD for solids treatment. Transportation & Traffic Operational truck trips would not affect traffic or circulation system performance on local or regional roadways. L l f bi lid ld d ffi N/A Local reuse of biosolids would reduce traffic

• n state freeways associated with hauling

and disposal of biosolids out of region/state
