Preliminary Environment SiEgy-ICPUS9 <br /> particulate matter (PM10). At the federal level, EPA has also designated this area as being a <br /> nonattainment area for 03 (8-hour standard), PM10, and PM2.5- <br /> Selected Criteria Pollutants: Attainment Status for the South Coast Air Basin (SCAB) <br /> Status <br /> Pollutants Federal State <br /> 03(one-hour standard) — Extreme Nonattainment <br /> 03(eight-hour standard) Nonattainment,Severe-17 — <br /> PM10 Serious Nonattainment Nonattainment <br /> PM2.5 Nonattainment Nonattainment <br /> CO Attainment Attainment <br /> NO2 Undassified/Attainment Attainment <br /> S02 Attainment Attainment <br /> 6. Is the project exempt from the requirement that a conformity determination be made? (If <br /> "Yes," state which conformity exemption in 40 CFR 93.126, Table 2 applies). Yes, the proposed <br /> project is exempt from the requirement to determine conformity under the Safety heading in 40 CFR <br /> 93.126 (railroad/highway crossing). However, an Air Quality Report will be prepared to address any <br /> potential operational or construction period impacts. <br /> 7. Is the project exempt from regional conformity? (If "Yes," state which conformity exemption <br /> in 40 CFR 93.127, Table 3 applies). Not applicable based on response to Question 6. <br /> 8. If project is not exempt from regional conformity? (If "No" on Question #7). Not applicable <br /> based on response to Question 6. <br /> Hazardous Materials/Hazardous Waste <br /> 9. Is there potential for hazardous materials (including underground or aboveground tanks, etc.) <br /> and/or hazardous waste (including oil/water separators, waste oil, asbestos-containing <br /> material, lead-based paint, ADL, etc.) within or immediately adjacent to the construction area? <br /> Based on a review of readily available database information, it is not anticipated that any hazardous <br /> materials or waste sites would be impacted by the proposed project as no known sites were identified <br /> within limits of disturbance for the proposed project and it is not anticipated that the project would <br /> impact groundwater. A review of the California Department of Toxic Substances' EnviroStor <br /> database revealed that the nearest site that utilizes hazardous waste and substances on site is the <br /> Orange County Register (located at 625 N. Grand Avenue). This site is located approximately 800 <br /> feet south of the east end of the project site. However, although not identified in the database search, <br /> a field review of the project site indicated that several industrial and warehouse type uses are present <br /> and these have a high potential for using or storing hazardous materials. In particular, the County <br /> Maintenance Yard located at 1102 Fruit Street has gas pumps and above ground tanks on site, and a <br /> hazardous materials placard was identified on the Orange County Public Works property located at <br /> 1143 Fruit Street. The Initial Site Assessment (ISA) that is prepared for the proposed project will <br /> further evaluate the potential for hazardous materials/waste concerns related to the proposed project. <br /> Water Quality <br /> 10. Does the project have the potential to impact water resources (rivers, streams, bays, inlets, <br /> lakes, drainage sloughs) within or immediately adjacent to the project area? There are no <br /> rivers, streams, bays, inlets, lakes, or drainage sloughs located within or immediately adjacent to the <br /> proposed project based on an initial field review of the project site. While the project is not located <br /> near any rivers, streams, bays, inlets, lakes, or drainage sloughs, the project areas drainage system <br /> 3 <br />
