Air Treatment Facility & Street Vacation at Mission Road & Jesse Street(Archived)

An Initial Study/Mitigated Negative Declaration (IS/MND) is available for review for the Air Treatment Facility at Mission Road and Jesse Street project. The proposed project involves the construction and operation of a sewer air treatment facility (ATF) near the intersection of Mission Road and Jesse Street, at 651 South Mission Road as well as the vacation of two street segments immediately adjacent to the project site. Near the intersection of Mission Road and Jesse Street, wastewater drops approximately 23 feet from the shallower North Outfall Sewer (NOS) to the deeper ECIS. The turbulence created by this drop releases foul air. The ATF is intended to treat this foul air resulting from the turbulent flow. The ATF would treat foul air emitted from the ECIS and would include two-stage treatment, with biotrickling filtration (BTF) vessels as the first stage and activated carbon absorption as the second stage. The BTF vessels would remove hydrogen sulfide and some odorous volatile organic compounds (VOCs), while the carbon units would remove the majority of the remaining VOCs and odors. The project would be constructed on approximately one-third of an acre and include three BTFs, four carbon units, one 25-foot tall exhaust stack, a fan building, a standby generator, a transformer, and a recirculation pit. These facilities would be located south of the existing Mission & Jesse drop structure located in the most northern area of the site. Although the proposed project could have a significant effect on biological resources, there would not be a significant effect as a result of the implementation of the identified mitigation measure.
