<br />Environmental Checklist
<br />environment. Hazardous materials include, but are not limited to, hazardous substances, hazardous
<br />wastes, and any material that a business or the local implementing agency has a reasonable basis for
<br />believing would be injurious to the health and safety of persons or harmful to the environment if
<br />released into the workplace or the environment.
<br />There are multiple state and local laws that regulate the storage, use, and disposal of hazardous
<br />materials. The County of Orange Environmental Health Division was designated by the State
<br />Secretary for Environmental Protection on January 1, 1997, as the Certified Unified Program Agency
<br />(CUPA) for Orange County (County of Orange Health Care Agency Environmental Health Services
<br />2011), including the City of Santa Ana. The CUPA is the local administrative agency that coordinates
<br />the following six programs regulating hazardous materials and hazardous wastes: Hazardous Waste,
<br />Underground Storage Tanks (UST), Aboveground Petroleum Storage Tanks (APST), Hazardous
<br />Materials Disclosure (HMD), Business Plan, and California Accidental Release Program (CalARP).
<br />Additionally, the Orange County Code of Ordinances provides regulations for the use and storage of
<br />hazardous materials. Section 3 -3 -14 of Chapter 27 requires the Orange County Fire Authority
<br />Chemical Classification packet to be completed and approved prior to approval of plans and /or the
<br />storage, use, or handling of chemicals on any premise.
<br />Currently, the project site contains asphalt, cement, building pads, a large pile of rubble, and sand
<br />bags and does not contain any hazardous materials. The proposed construction activities would
<br />involve the transport, use, and disposal of hazardous materials such as paints, solvents, oils, grease,
<br />and caulking. In addition, hazardous materials would be needed for fueling and servicing
<br />construction equipment on the site on a temporary basis. These types of materials are commonly
<br />used during new building construction and are not acutely hazardous. Furthermore, all storage,
<br />handling, use, and disposal of these materials are regulated by Orange County regulations, which the
<br />project construction activities are required to strictly comply with. As a result, hazardous material
<br />impacts related to construction activities would be less than significant.
<br />Operation of the proposed project includes residential and school activities, which generally use
<br />hazardous materials including solvents, cleaning agents, paints, pesticides, batteries, and aerosol
<br />cans. Although the project would utilize common types of hazardous materials, normal routine use
<br />of these products would not result in a significant hazard to residents or workers in the vicinity of
<br />the project. Therefore, operation of the proposed project would not result in a significant hazard to
<br />the public or to the environment through the routine transport, use, or disposal of hazardous waste
<br />during operation of the proposed project. Impacts would be less than significant.
<br />b. Create a significant hazard to the public or the environment through reasonably foreseeable
<br />upset and accident conditions involving the release of hazardous materials into the
<br />environment?
<br />Less - than - Significant Impact. Former hospital and medical office buildings at the site involved the
<br />presence and routine use of hazardous materials. However, as a result of previous clean -up
<br />activities, testing has not identified any remaining hazardous materials on the project site. An
<br />Environmental Site Assessment prepared in June 2011 (Athanor 2011b) determined that potential
<br />asbestos - containing materials existed in the former hospital buildings that date back to 1964. The
<br />potentially asbestos - containing materials were abated, and prior to demolition, the air monitoring
<br />was completed, which confirmed that all air sample results are within the guidelines established by
<br />the Environmental Protection Agency (EPA) for reoccupation of an area that has undergone
<br />asbestos abatement. In addition, an underground storage tank (UST) previously existed within the
