Sierra Chemical Co. <br />RCRA Contingency Plan <br />Spill or release involving materials excluded according to the SARA Title III, Statute 42 <br />USC 11021(e) such as: <br />• Any substance present in the same form and concentration as a product <br />packaged for distribution and use by the general public. <br />• Any substance to the extent it is used in the laboratory under the direct <br />supervision of a technically qualified individual. <br />• Petroleum, including crude oil or any fraction thereof, which is not otherwise <br />specifically listed or designated as a hazardous substance by CERCLA. <br />Incident Level I: According to the NFPA 471, Responding to Hazardous Materials Incidents (see <br />figure 3.1), if the product(s) involved in the spill or leakage meet the following criteria, it will be <br />classified as a Level I incident and does not implement the Contingency Plan. <br />a. The product does not require a U.S. DOT placard, is an NFPA 0 or 1 for all categories, <br />and it Other Regulated Materials A, B, C, or D. <br />b. The spill or explosion is under control, and the reactivity rating of the material is less <br />than a rating of 2, indicating a low potential for a subsequent explosion as the <br />hazardous material can be considered generally stable. <br />c. There was no release, or the release can be confined with readily available resources. <br />d. There is no life-threatening situation. <br />e. There is no potential for environmental impact. <br />4. Incident Level II: According to NFPA 471, Responding to Hazardous Materials Incidents (see <br />figure 3.1), if the product(s) involved in the fire, explosion, spill or leakage meet the following <br />criteria, it will be classified as a Level II incident and the Contingency Plan will be implemented <br />by the Emergency Coordinator. <br />a. The product(s) requires a DOT placard, is an NFPA 2 for any categories, or is an EPA <br />regulated waste. <br />b. The incident involved multiple packages. <br />c. There is potential for the fire to spread from the hazardous material's flammability level <br />(rating 2) is below 200 degrees Fahrenheit or the reactivity (rating 21 indicates that <br />violent chemical changes are possible and thus may be explosive. <br />d. The release may not be controllable without special resources. <br />e. The incident requires evacuation of a limited area of life safety. <br />f. The potential for environmental impact is limited to soil and air within incident <br />boundaries. <br />g. The container is damaged but able to contain the contents to allow handling or transfer <br />of product. <br />5. Incident Level III: According to NFPA 471, Responding to Hazardous Materials Incidents (see <br />figure 3.1), if the product(s) involved in the fire, explosion, spill or leakage meet the following <br />criteria, it will be classified as a Level III incident and the Contingency Plan will be implemented <br />by the Emergency Coordinator. <br />a. The product is a poison A (gas), an explosive A/B, organic peroxide, flammable solid, <br />material that is dangerous when wet, chlorine, fluorine, anhydrous ammonia, NFPA 3 <br />and 4 for any categories including special hazards, EPA extremely hazardous substances <br />(FHS), and cryogenics. <br />b. The site-specific container size for this incident level will be a tank truck. <br />c. There is potential for the fire to spread because the hazardous material's flammability <br />level (rating 3 or 4) is below 100 degrees Fahrenheit, or the reactivity (rating 3 or 4) <br />indicates that the material may explode. <br />d. The release may not be controlled even with special resources. <br />Prepared By: <br />Issue date: <br />Replaces: <br />Page: <br />ACT Environmental Services, Inc. <br />February 25, 2016 <br />NA <br />12 of 44 <br />
