Allow IRWD to make efficient and sustainable use of its renewable resources

• To make beneficial use of biosolids and biogases produced

during the treatment process during the treatment process

• Provide for greater control of residual (solids) management at

reduced costs

• Minimize environmental impacts associated with residuals

management Construct a biosolids handling and energy recovery facility

• Construct a biosolids handling and energy recovery facility

that adequately provides for future biosolids handling needs

• f the MWRP Phase 2 and 3 Capacity Expansion Project

Project Description

• IRWD to construct facilities at MWRP

for:

• Biosolids processing
• Biogas management & energy

recovery

• Odor control system
• IRWD would no longer export solids to

Orange County Sanitation District (OCSD)

• Project would dry solids from IRWD’s

Summary of Impacts and Mitigations

Impact Category Significance Level Mitigation Measure Summary

Aesthetics Less than significant with mitigation

• Selecting paint color schemes that blend with the

existing environment

The project would have no significant unavoidable impacts
