Rule 3745-52-265 | Emergency procedures - preparedness, prevention, and emergency procedures for large quantity generators.


(A) When there is an imminent or actual emergency situation, the emergency coordinator (or the emergency coordinator's designee when the emergency coordinator is on call) shall immediately:

(1) Activate internal facility alarms or communication systems, where applicable, to notify all facility personnel; and

(2) Notify appropriate state or local agencies with designated response roles if help is needed.

(B) When there is a release, fire, or explosion, the emergency coordinator shall immediately identify the character, exact source, amount, and areal extent of any released materials. The emergency coordinator may do this by observation or by review of the generator's records or manifests and, if necessary, by chemical analysis.

(C) Concurrently, the emergency coordinator shall assess possible hazards to human health or the environment that may result from the release, fire, or explosion. This assessment shall consider both direct and indirect effects of the release, fire, or explosion (e.g., the effects of any toxic, irritating, or asphyxiating gases that are generated, or the effects of any hazardous surface water run-offs from water or chemical agents used to control fire and heat-induced explosions).

(D) If the emergency coordinator determines that the facility has had a release, fire, or explosion which could threaten human health or the environment outside the facility, the emergency coordinator shall report the findings as follows:

(1) If the assessment indicates that evacuation of local areas may be advisable, the emergency coordinator shall immediately notify appropriate local authorities. The emergency coordinator shall be available to help appropriate officials decide whether local areas should be evacuated; and

(2) The emergency coordinator shall immediately notify either the government official designated as the on-scene coordinator for that geographical area, or the Ohio EPA spill hotline at 800/282-9378. The report shall include:

(a) Name and telephone number of the person making the report;

(b) Name and address of the generator;

(c) Time and type of incident (e.g., release, fire);

(d) Name and quantity of materials involved, to the extent known;

(e) The extent of injuries, if any; and

(f) The possible hazards to human health or the environment outside the facility.

(E) During an emergency, the emergency coordinator shall take all reasonable measures necessary to ensure that fires, explosions, and releases do not occur, recur, or spread to other hazardous waste at the generator's facility. These measures shall include, where applicable, stopping processes and operations, collecting and containing released hazardous waste, and removing or isolating containers.

(F) If the generator stops operations in response to a fire, explosion, or release, the emergency coordinator shall monitor for leaks, pressure buildup, gas generation, or ruptures in valves, pipes, or other equipment, wherever this is appropriate.

(G) Immediately after an emergency, the emergency coordinator shall provide for treating, storing, or disposing of recovered waste, contaminated soil or surface water, or any other material that results from a release, fire, or explosion at the facility. Unless the generator can demonstrate, in accordance with paragraph (C) or (D) of rule 3745-51-03 of the Administrative Code, that the recovered material is not a hazardous waste, the recovered material is a newly generated hazardous waste that shall be managed in accordance with the applicable requirements and conditions for exemption in Chapters 3745-52, 3745-53, 3745-65 to 3745-69, and 3745-256 of the Administrative Code.

(H) The emergency coordinator shall ensure that, in the affected areas of the facility:

(1) No hazardous waste that may be incompatible with the released material is treated, stored, or disposed of until cleanup procedures are completed; and

(2) All emergency equipment listed in the contingency plan is cleaned and fit for the emergency equpment's intended use before operations are resumed.

(I) The generator shall note in the operating record the time, date, and details of any incident that requires implementation of the contingency plan. Within fifteen days after the incident, the generator shall submit a written report on the incident to the director. The report shall include:

(1) Name, address, and telephone number of the generator;

(2) Date, time, and type of incident (e.g., fire, explosion);

(3) Name and quantity of materials involved;

(4) The extent of injuries, if any;

(5) An assessment of actual or potential hazards to human health or the environment, where this is applicable; and

(6) Estimated quantity and disposition of recovered material that resulted from the incident.
