The three-level response plan for hazardous materials incidents is characterized as Level I Response, Levd Il Response and Level Ill response. The distinction between Levels I, H, and tli depends on: a) class of hazardous material b) size of container c) fire/explosion potential d) ~eak severity and container integrity, and e) threat to life safety. Level I Responses are those incidents readily controlled or stabilized by first responders. The HazMat Emergency Response Team personnel may provide technical assistance via telephone or omsite assistance, but full response by an Emergency Response Team is not required, Level Il Responses are those incidents that require response from a HazMat Emergency Response Team for control or stabilization of the spill. The Emergency Response Team response level may be 2-4 personnel for identification of the matedal and guidance on appropriate response actions or the response level may be a small team response of 6-8 personnel. Level III Responses are those incidents that require specia~ resources, including one or more full Emergency Response Teams and possibly other outside agencies for support. Further technical details of the Level I, II, and III responses are given in the Standard Operating Guidelines, Levels of Response to Hazardous Materials Incidents, %003.3 A very useful glossary of technical terms used for hazardous materials incidents is given in the Glossary of Terms (Standard Operating Guidelines, Glossary of Terms, SOG-T002.3) 14.4 Statutory and Regulatory Context The manufacture, storage, use, transportation, and disposal of hazardous materials are subject to a myriad of federal, state, and local regulations. In the context of mitigation planning and emergency response, we focus on reporting requirements for chemicals subject to mandatory risk management planning and extremely hazardous substances subject to additional reporting and planning requirements. Section 112(r) of the Clean Air Act Amendments was designed to prevent accidental releases of hazardous substances. The rule establishes a list of chemicals and threshold quantities that identify facilities subject to subsequent accident prevention regulations. The listed substances have the greatest potential to pose the greatest hazard to public health and the environment in the event of an accidental release. The full list of Section 112(0 chemicals, including planning threshold quantities (TPQ) is given in Appendix 1, Table A1.1 of the Phase Three Plan. Public Review Draft: October 12, 2004 14-5
