I-4.2.3 Description of the Waste Left in Place The wastes treated at the former B-829 Facility were hazardous primarily because of their reactivity. The four principal explosives compounds that were treated at the B-829 Facility were HMX(cyclotetramethylene tetranitramine), RDX(cyclotrimethylene trinitramine),TATB (triamino-trinitrobenzene)and TNT(2,4,6-trinitrotoluene). Explosives and explosives- contaminated wastes were generated from explosives formulation,the manufacturing process, and detonation testing on the firing tables. The wastes included pieces of undetonated explosives, miscellaneous burnable materials that are judged to be contaminated with explosives, and fines collected in clarifiers from explosives materials machining. After burning,the waste residue consisted of non-reactive ash and potentially unreacted explosive hazardous waste. Small amounts of solvent,plastic and metal may also remain in the pits. I4.3 RESPONSIBILITIES This Contingency Plan utilizes the Incident Command System to coordinate activities of personnel during an emergency at Site 300. Section 4 of this Plan describes the individual responsibilities during an emergency at Site 300. This Section presents the responsibilities of B- 829 support personnel during an emergency. For incidental releases and minor, first-aid injuries at the B-829,the B-829 Facility Manager or designated alternate, manages the incident.These individuals and their phone numbers are listed in Table I-4-3. If additional support is needed during a minor incident,the Facility Representative will contact the Environment, Safety, and Health(ES&H) Support Team members, if necessary. For most other non-security emergencies, the first or senior Fire Department Officer dispatched to,or present at the scene becomes the IC until relieved by a Chief Officer.

The Fire Department emergency action levels are defined according to the event and the potential hazard to onsite personnel and offsite persons.
