Responses to <br />Environmental Checklist <br />For CEQA Compliance <br />the nearest sensitive receptor, it is conservatively estimated that Fong-term <br />operation of the proposed lift station may result in a significant odor impact for <br />which mitigation would be required. <br />Mitigation Measures: <br />MM-~ In order to ensure that odor impacts to nearby sensitive receptors are reduced to a <br />level below significant, a passive odor control system shall be incorporated into the <br />design of the lift station facility. The system shall consist of an absorber vessel <br />(drum) with activated carbon. The drum shall be connected to the wet well by PVC <br />ducting. The air flow shall be variable and dependent on the inflow into the wet well <br />and the raising and lowering of the water surface within the wet well. The activated <br />carbon shall be designed so as to scrub sewage gases and remove odor-causing <br />hydrogen sulfide gas before venting to the atmosphere through the roof of the lift <br />station. <br />Significance After Mitigation.: <br />Implementation of Mitigation Measure MM-7 would ensure that future operation of the lift <br />station facility does not expose nearby sensitive receptors to offensive odors. With <br />incorporation of the required mitigation, impacts due #o odors would be reduced to a level <br />below significant. <br />iV.

Have a substantial adverse impac>y either directly or through habitat <br />modifications, on any species identified as a candidate, sensitive or specia! status <br />species in local or regional plans, policies or regulations or by the California <br />Department of Fish and Game (CDFG) or U.S. Fish and Wildlife Services <br />(USFWS}? <br />Finding: No Impact. <br />Analysis: The project area is characterized as an urban area that exhibits no natural <br />habitats. As such, implementation of the proposed project would not result in any <br />adverse impacts, either directly or through habitat modifications, on any species <br />identified as a candidate, sensitive, or special status species in any plans, <br />policies, or regulations of the CDFG or USFWS. <br />B. Have a substantial adverse impact on any riparian habitat or natural community <br />ident~ed in local or regional plans, policies, and regulations or by the California <br />Department of fish and Game or U.S. Fish and Wildlife Service? <br />Fin. dins: No impact. <br />Page 41 of 64 <br />75E-45 <br />
