| SUPERFUND |
The program operated under the legislative authority of the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA) and the Superfund Amendments and
Reauthorization Act (SARA) that funds and carries out the solid waste emergency response and long-term remedial activities of the EPA. |
| SURFACE IMPOUNDMENT |
A natural topographic depression, man-made excavation, or diked area formed
primarily from earthen materials (though it may be lined with man-made materials) that is designed
to accumulate liquid wastes or wastes containing free liquids, and that is not an injection well (40
CFR 260.10). |
| TOLLING |
Tolling arrangements describe a particular type of recycling contract between two companies.
Specifically, the 'tolling' company certifies that it has a contract with a manufacturer to produce a
product, and that manufacturing process generates a residual material that can be recycled by the
tolling company. If the tolling company certifies that the contract specifies that the tolling company
owns and has responsibility for the recyclable material once it is generated, and the material is
returned to the tolling company for reclamation, and subsequently recycled, the material is
excluded from regulation (under 40 CFR 261.2(a)(2)(ii) or 261.4(a)(23)), provided certain
requirements are met. |
| TRANSFER FACILITY |
Any transportation-related facility including loading docks, parking areas, storage
areas, and other similar areas where shipments of hazardous waste are held for 10 days or less
during the normal course of transportation (40 CFR 260.10 and 40 CFR 263.12). |
| TRANSPORTER |
A person engaged in the off-site transportation of hazardous waste by air, rail, highway,
or water. |
| UNDERGROUND INJECTION CONTROL |
The subsurface emplacement of fluids through a bored, drilled or
driven well; or through a dug well, where the depth of the dug well is greater than the largest
surface dimension. Underground injection wells are regulated under both the Safe Drinking Water
Act and the Resource Conservation and Recovery Act (see 40 CFR Part 148). |
| UNIT |
Refer to 'Process Unit' definition. |
| UNITED STATES IMPORTER |
Any person who imports hazardous waste from a foreign country into the
United States. This does not include hazardous waste shipped from a foreign Department of
Defense site, Maquiladora, United States territory or protectorate. |
| UNIVERSAL WASTE |
Any of the following hazardous wastes that are managed under the universal waste
requirements of 40 CFR Part 273: batteries, pesticides, mercury-containing equipment, and lamps.
Some States may have State-specific universal wastes defined as well. |
| USED OIL |
Any oil that has been refined from crude oil, or any synthetic oil, that has been used, and as a
result of such use, is contaminated by physical or chemical impurities. |
| USED OIL FUEL MARKETER |
Any person who conducts either of the following activities:
1. Directs a shipment of off-specification used oil from their site to an off-specification used oil
burner; or
2. First claims that used oil that is to be burned for energy recovery meets the used oil fuel
specifications set forth in 40 CFR 279.11. |
| USED OIL MANAGEMENT ACTIVITIES |
For the purposes of the Site ID Form, includes used oil transportation;
used oil processing and re-refining; burning off-specification used oil fuel; and used oil fuel
marketing. |
| USED OIL PROCESSING |
Chemical or physical operations designed to produce from used oil, or to make
used oil more amenable for production of, fuel oils, lubricants, or other used oil-derived products.
Processing includes, but is not limited to: blending used oil with virgin petroleum products, blending
used oils to meet the fuel specification, filtration, simple distillation, chemical or physical separation,
and re-refining. |
| USED OIL PROCESSOR |
A site that processes on-specification or off-specification used oil. |
| USED OIL RE-REFINER |
A site that produces lubricating oils and greases, industrial fuel, asphalt extender,
gasoline, and other products from on-specification or off-specification used oil. |
| USED OIL TRANSFER FACILITY |
Any transportation-related facility, including loading docks, parking areas,
storage areas, and other areas where shipments of used oil are held for more than 24 hours during
the normal course of transportation and not longer than 35 days. Transfer facilities that store used
oil for more than 35 days are subject to regulation under 40 CFR Part 279, Subpart F. |
| USED OIL TRANSPORTER |
Any person who transports used oil, any person who collects used oil from more
than one generator and transports the collected oil, and owners and operators of used oil transfer
facilities. Used oil transporters may consolidate or aggregate loads of used oil for purposes of
transportation but, with the following exception, may not process used oil. Used oil transporters
may conduct incidental processing operations that occur in the normal course of used oil
transportation (e.g., settling and water separation), but that are not designed to produce (or make
more amenable for production of) used oil-derived products or used oil fuel. |
| WASTE MINIMIZATION |
The reduction, to the extent feasible, of hazardous waste that is generated or
subsequently treated, stored, or disposed. It includes any source reduction or recycling activity
undertaken by a generator that results in: (1) the reduction of total volume or quantity of
hazardous waste; (2) the reduction of toxicity of hazardous waste; or (3) both, as long as the
reduction is consistent with the goal of minimizing present and future threats to human health and
the environment. |
| WASTE OIL (BIENNIAL REPORT ONLY) |
Any oil that has been refined from crude oil, or any synthetic oil, that
has been used, and as a result of such use, is contaminated by physical or chemical impurities and is
managed as a hazardous waste. |
| WR FORM |
Waste Received From Off-site Form. |
