OU2 Groundwater Containment Facility

OU2 Groundwater Containment Facility

The City of Santa Fe Springs, in its capacity as the Lead Agency, is considering for the construction of a groundwater treatment project located at 10051 Santa Fe Springs Road within the City of Santa Fe Springs. The project is a Superfund response action and is needed to address contaminated groundwater as part of Operable Unit 2 of the Omega Chemical Superfund Site. The U.S. Environmental Protection Agency (EPA) will oversee the work. It is EPA policy to assure that all activities conducted under Superfund response actions are protective of human health and the environment. There was a Mitigated Negative Declaration (MND) that was prepared for a larger warehouse distribution project that was approved by the City though the original project was never implemented. This former approved project referred to above, included the subdivision of the larger 44.67 acre parcel into 5 parcels, and the development of a 17.90-acre portion (parcels 1 through 4) of the larger 44.67-acre site. The current groundwater treatment project would be located within one of the five parcels (Parcel No. 4) which is located within the northeast corner of the larger site. Parcel 4 has a total land area of 3.23 acres (140,791 square feet) and under the previous development scenario was approved for a new 60,117 square-foot warehouse. The groundwater treatment project site is located at the corner of McCann Drive and Santa Fe Springs Road and would occupy the aforementioned Parcel 4. The site’s legal address is 10051 Santa Fe Springs Road with a corresponding Assessor Parcel Number (APN) of 8005-015-050. The site is surrounded on all sides by industrial development. The total building area for the proposed groundwater treatment plant would equal 48,515 square feet. The proposed project site has a land use and zoning designation of M-2 Heavy Manufacturing and would require a Conditional Use Permit (CUP) for Water Pumping and Treatment Plants. None of the nine remaining oil wells are located within the Parcel 4 boundary, nor would they affect the redevelopment of Parcel 4 for the use as a groundwater treatment facility. In other words, the development of the proposed groundwater treatment facility would not interfere with any ongoing oil extraction activities within the adjacent parcels. The project also includes the construction and operation of up to seven groundwater extraction wells at four well sites to pump groundwater to the treatment plant via below-grade conveyance pipelines. The groundwater pipelines (untreated) would be double contained and constructed of HDPE to pump groundwater to the treatment plant via below-grade conveyance pipelines. Finally, the project will require construction of a new outfall where the treated groundwater would be conveyed to the San Gabriel River.
