Mill tailings or any waste that contains commercial asbestos and is generated by a source subject to the provisions of this subpart. This term includes filters from control devices, friable asbestos waste material, and bags or other similar packaging contaminated with commercial asbestos. As applied to demolition and renovation operations, this term also includes regulated asbestos-containing material waste and materials contaminated with asbestos, including disposable equipment and clothing.
Industry:Energy; Oil & gas
An approach to radiation protection to control or manage exposures (both individual and collective to the work force and the general public) and releases of radioactive material to the environment as low as social, technical, economic, practical, and public policy considerations permit. As used in this Order, ALARA is not a dose limit, but rather it is a process that has its objective the attainment of dose levels as far below the applicable limits of the Order as practicable.

Technologies and methods for emplacing a permanent radon barrier on uranium mill tailings piles or impoundments. This term shall not be construed to include extraordinary measure or techniques that would impose costs that are grossly excessive as measured by practice within the industry or one that is reasonably analogous (such as, by way of illustration only, unreasonable overtime, staffing or transportation requirements, etc., considering normal practice in the industry; laser fusion, of soils, etc.), provided there is reasonable progress toward emplacement of a permanent radon barrier. To determine grossly excessive costs, the relevant baseline against which cost increases shall be compared is the cost estimate for tailings impoundment closure contained in the licensee’s tailings closure plan, but costs beyond such estimates shall not automatically be considered grossly excessive.

During the Site Characterization phase of an RI/FS, a baseline risk assessment (RA) is used to evaluate the potential threat to human health and the environment in the absence of any remedial action. That is, the baseline RA describes the risk conditions under the “no action alternative.” The baseline RA is extremely important because it provides the basis for determining whether remedial action is necessary. It also determines the extent of cleanup needed to reduce potential risk levels to within EPA's acceptable range [e.g., carcinogenic risks of 10-4 to 10-6 - 40 CFR 300.430(e)(2)(i) (A)(2)].

The liquid buildup and eventual overflow due to precipitation which enters the unit through the cover but cannot escape through the bottom liner.
Industry:Energy; Oil & gas
Microbiological cultures, enzyme additives, or nutrient additives that are deliberately introduced into an oil discharge and that will significantly increase the rate of biodegradation to mitigate the effects of the discharge.
Industry:Energy; Oil & gas
The closure of a hazardous waste management unit in accordance with the applicable closure requirements of Parts 264 and 265 of this chapter at a facility that contains other active hazardous waste management units. For example, partial closure may include the closure of a tank (including its associated piping and underlying containment systems), landfill cell, surface impoundment, waste pile, or other hazardous waste management unit, while other units of the same facility continue to operate.
Industry:Energy; Oil & gas
Any enclosed thermal treatment device that is used to dehydrate sludge and that has a maximum total thermal input, excluding the heating value of the sludge itself, of 2,500 Btu/lb of sludge treated on a wet-weight basis.
Industry:Energy; Oil & gas
An operation or method of separation in which a solid or solution is contacted with a liquid solvent (the two being mutually insoluble) to preferentially dissolve and transfer one or more components into the solvent.
