Environmental Protection Agency needs

With reference to Figure 4, each piston down-stroke provides power, while each upstroke provides compression of the blower/turbo-supplied cylinder air. The actual number of degrees of both of these strokes will vary based on the specific engine make and model, and its year of manufacture needed to comply with U.S. Environmental Protection Agency (EPA) exhaust emission limits. 

The Environmental Protection Agency (EPA) and other federal, state and local authorities govern security of supply in relation to quantity for surface and groundwater by the granting of an abstraction license. The license limits the total daily quantity and the rate at which the waters may be abstracted, taking account of the natural resource and the needs of other abstractors. Metered water supply is subject to contract with the water companies, who may impose quantity and draw-off rate limitations. The limitations imposed by the license or contract may influence plant location. 

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) [42 U.S.C. 9601 et seq.], as amended by the Superfund Amendments and Reauthorization Act (SARA) [Pub. L. 99 99], requires that the Agency for Toxic Substances and Disease Registry (ATSDR) develop jointly with the U.S. Environmental Protection Agency (EPA), in order of priority, a list of hazardous substances most commonly found at facilities on the CERCLA National Priorities List (NPL) prepare toxicological profiles for each substance included on the priority list of hazardous substances and assure the initiation of a research program to fill identified data needs associated with the substances. 

Industrial scientists, therefore, hold a very high public trust. There is a need to go beyond the requirements of scientific canons and demonstrate to the lay public that its trust has been upheld. A number of industrial firms have recognized and responded to this need. Wilder, of Eastman Chemical, for example, describes a proactive pollution prevention policy developed in partnership with the Environmental Protection Agency.112 This work describes the key role of analytics in helping chemical manufacturers take leadership roles in redesigning processes for waste prevention. Since the analytical laboratory is a principal referee in the production process, there is always a risk that time pressures will tempt some members of the production team to "work the referee". An important function of the chain of command of the analytical laboratory, therefore, is establishing a clear operational policy to ensure that any such pressure does not reach the bench level ... 

Recognizing the need to prevent pollution and minimize waste, governments, through their environmental protection agencies, should continue their catalytic role to promote, (with industry, research organizations and other relevant institutions) the establishment of a network that will allow the transfer of environmental protection technology.

Where complete containment is impractical, exhaust ventilation (preferably to a scrubber) can limit or eliminate exposure to toxic materials. The exhaust ventilation rate (velocity or volumetric rate) may be calculable for volatile liquids from spill size and vapor pressure (U.S. Environmental Protection Agency, Risk Management Program Guidance for Offsite Consequence Analysis, Appendix D, Equation D-l, 1999), but tests to determine concentrations in air usually would be needed for dusty processes and fugitive releases of gases.
