5.5 HAZARDOUS MATERIALS HANDLING state laws apply only to petroleum products that might be discharged to navigable waters. If stored quantities are equal to or greater than 660 gallons for a single container, or equal to or greater than 1,320 gallons total (including tanks, oil-filled equipment,and drums), an SPCC plan must be prepared. The existing STIG plant has an SPCC plan in place,however the plan will be updated to include the additional petroleum products stored on site at the LEC plant. 5.5.4.2.5 Transportation/Delivery of Hazardous Materials and Regulated Substances Hazardous materials and anhydrous ammonia,a regulated substance,will be delivered periodically to the facility. As discussed in Section 5.12,Traffic and Transportation, transportation of hazardous materials will comply with all Caltrans,EPA,DTSC, CHP,and California State Fire Marshal regulations. Under the California Vehicle Code,the CHP has the authority to adopt regulations for transporting hazardous materials in California. The CHP can issue permits and specify the route for hazardous material delivery. Anhydrous ammonia will be delivered to the facility, and transported in accordance with Vehicle Code Section 32100.5,which regulates the transportation of hazardous materials that pose an inhalation hazard. In addition, ammonia will only be transported along approved transportation routes. The recommended routes, subject to Caltrans approval, are as follows: • Coming from Sacramento and points north: from I-5 exit at SR 12 interchange then turn south onto North Thornton Road,west on Frontage road, and south on North Cord Road; • Coming from Stockton and points south:from 1-5 exit at West Eight Mile Road interchange then turn north onto North Thornton Road,west on Frontage road, and south on North Cord Road; Outbound trucks would proceed on 1-5 to access hazardous waste facilities throughout the state. Currently the existing anhydrous ammonia tank is refilled once a year for the STIG facility. With the addition of the LEC facility, deliveries will increase to two times per month,with a maximum of 24 deliveries per year. A transportation risk analysis was also prepared for this project to determine the risk of delivering ammonia to LEC (Appendix 5.5A). The risk of an incident occurring during a calendar year that would result in 10 or more fatalities is 0.017/million miles x 73.9 miles, or 1.26 in one million. The risk of an accident occurring in any year that would result in 33 or more fatalities is 0.0027/million miles x 73.9 miles, or 0.20 in one million. The CEC uses a significance threshold of 1 in 100,000 (or 10 in 1,000,000) for a risk of 10 fatalities and a threshold of 1 in 1,000,000 for a risk of 100 fatalities (CEC,2001). Both of the project's risk estimates (1.26 and 0.20 in one million) are well below the CEC thresholds.Therefore,the risk of exposure to aqueous ammonia during transport to the LEC site is not significant. 5.5.4.2.6 Security Plan In addition to standard industrial business security measures,the Applicant will be preparing a security plan that will include the following elements: • Descriptions of the site fencing and security gate 5.5-26 SAC/371322/082330015(LEC_5.5_HAZMAT.DOC)
