Hazardous waste accumulation areas

Hazardous Waste Storage Standards for an Accumulation Area... 

The accumulation or storage area of an industrial plant (i.e., a generator) must meet the following conditions for both containers and tanks in accordance with the home State regulations. The Massachusetts hazardous waste regulations (310 CMR 30.000) are listed below as a reference ... 

Any spillage must be promptly removed in general, if the hazardous waste being stored has no free liquids, no pad is required, provided that the accumulation area is sloped, or the containers are elevated. 

The central accumulation area is an important component in the organization s chemicals management plan. In addition to being the primary location where waste management occurs, it may also be the location where excess chemicals are held for possible redistribution. Along with the laboratory, the central accumulation area is often where hazard reduction of waste takes place through allowable on-site treatment processes. 

Waste materials stored within a central accumulation area should be held in appropriate and clearly labeled containers, separated according to chemical compatibility as noted in the previous section. The label must include the accumulation start date and the words "Hazardous Waste." Fire suppression systems, ventilation, and dikes to avoid sewer contamination in case of a spill should be considered when such a facility is planned. Training of employees in correct handling of the materials as well as contingency planning for emergencies is expected to be a part of the central accumulation area operations. 

Records are needed both to meet regulatory requirements and to help monitor the success of the hazardous waste management program. Because the central accumulation area is usually the last place where waste is dealt with before it leaves the facility, it is often the most suitable place for ensuring that all appropriate and required records have been generated. 

Uncontroited hazardous waste site means an area identified as an uncontrolled hazardous waste site by a governmental body, whether Federal, state, local or other where an accumulation of hazardous substances creates a threat to the health and safety of individuals or the environment or both. Some sites are found on public lands such as those created by former municipal, county or state landfills where illegal or poorly managed waste disposal has taken place. Other sites are found on private property, often belonging to generators or former generators of hazardous substance wastes. Examples of such sites include, but are not limited to, surface impoundments, landfills, dumps, and tank or drum farms. Normal operations at TSD sites are not covered by this definition. 

Central accumulation areas are the main storage areas for a facility s hazardous waste. 

Hazardous wastes stored in satellite accumulation areas have fewer regulatory requirements than wastes stored in central accumulation areas. EPA allows generators to accumulate up to 55 gallons of hazardous waste or one quart of acutely hazardous waste in containers at or mar the point of generation. Waste in these areas must always be emder the control of the operator of the process generating the waste. ...

Perhaps the least understood requirements of RCRA are those that apply to the accumulation of hazardous wastes. As previously noted, generators cannot store on-site longer than set time limits which are based on monthly rates of generation. There are, however, provisions for the storage of waste at the point of generation. This is limited to 55 gallons of waste per instance, and wastes must be stored in the immediate work area. 

Waste will be moved from the general laboratory work area to a central waste storage area at regular intervals to minimize volumes of hazardous materials accumulating in the laboratory. EPAs RCRA regulations state that the waste has to be removed 180 days from the date that the drum was started. 

Waste Storage Capacity - Provision should be made In the site layout for a waste storage facility (which may not be constructed until just prior to decommissioning If It Is Intended only for decommissioning wastes) to provide temporary storage space so that accumulated waste will neither slow down decommissioning nor be stored In areas which may pose exposure hazards.
