South Coast Technology Center Project
<br />CEQA Exemption 15183
<br />4.9.2 Project Analysis
<br />The proposed Project would develop three new Class A industrial buildings for office,
<br />manufacturing, and/or warehouse use on a site that is currently developed with commercial office
<br />buildings east of Susan Street and is vacant west of Susan Street. While the proposed Project
<br />would introduce new industrial uses to the Project Site, according to GPU PEIR Figure 2-1, EJ
<br />Communities, Neighborhoods, and Focus Areas, the Project Site is not located within an
<br />environmental justice (EJ) community. As such, the proposed Project would not expose EJ
<br />communities to hazardous materials and waste. Moreover, although the proposed Project would
<br />require an amendment to the SD-58 District to allow for industrial uses, the Project Site's land use
<br />designation is already Industrial. Thus, the proposed Project would not introduce any general or
<br />heavy industrial uses in the City in comparison to existing conditions.
<br />Construction of the proposed Project would involve demolition, grading, and construction of new
<br />buildings. Construction activities would use limited amounts of hazardous materials in the form of
<br />paints, solvents, glues, and other common construction materials for the proposed buildings.
<br />Construction activities may include the use of machinery and other equipment that require fueling
<br />or maintenance/servicing. These types of materials are not acutely hazardous, and all storage,
<br />handling, use, transport, and disposal of these would be required to conform to existing laws and
<br />regulations of the California Department of Toxic Substances Control (DTSC), USEPA,
<br />Occupational Safety & Health Administration (OSHA), and OCHCA, which would ensure that all
<br />potentially hazardous materials are used and handled in an appropriate manner and would
<br />minimize the potential for safety impacts to occur. Additionally, the storage, handling, use,
<br />transport, and disposal of these hazardous materials would cease once construction is complete.
<br />Project compliance with RR HAZ-1 would ensure hazardous materials and hazardous wastes are
<br />transported in compliance with any applicable state and federal requirements; RR HAZ-2 would
<br />ensure hazardous waste generation, transportation, treatment, storage, and disposal would be
<br />conducted in compliance with Subtitle C of the Resource Conservation and Recovery Act (Code
<br />of Federal Regulations [CFR], Title 40, Part 263). According to the Cultural Memorandum, the
<br />existing buildings were built after the 1980s; refer to Attachment C. Thus, the buildings are not
<br />likely to contain ACM and LBP. Nonetheless, demolition of the existing buildings would comply
<br />with RR HAZ-4, which would ensure demolition activities that could expose workers or the public
<br />to ACMs or LBPs would be conducted in accordance with any applicable state and federal
<br />requirements, and RR HAZ-5, which would ensure removal of hazardous materials be conducted
<br />as outlined in 29 CFR 1910.120 and 8 CCR 5192. Moreover, based on Attachment G, Phase /
<br />Environmental Site Assessment,23 the vacant parcel to the west of Susan Street does not have
<br />any recognized environmental conditions.24 Therefore, with adherence to existing regulations
<br />construction of the proposed Project would result in less than significant impacts related to the
<br />use, storage, transport, and disposal of hazardous wastes, as well as related to the accidental
<br />release of hazardous materials.
<br />During operation, there is potential for future tenants of the proposed buildings to use hazardous
<br />materials and generate hazardous waste. The nearest sensitive receptor is Calvary High School,
<br />located to the east of the Project Site. However, any future hazardous materials use, storage,
<br />23 Attachment G, Phase 1 Environmental Site Assessment is comprised of two Phase I reports — one for the vacant
<br />parcel and one for the Lake Center Office Park. For the purposes of this document, references to the Phase I
<br />Environmental Site Assessment includes both reports.
<br />24 As defined by ASTM E1527-21, a REC is: "(1) the presence of hazardous substances or petroleum products in, on,
<br />or at the subject property due to a release to the environment; (2) the likely presence of hazardous substances or
<br />petroleum products in, on, or at the subject property due to a release or likely release to the environment; or (3) the
<br />presence of hazardous substances or petroleum products in, on, or at the subject property under conditions that
<br />pose a material threat of a future release to the environment.
