Regulation abatement

If regulations governing specific emission limit VOC concentrations to the low ppm range then, of course, vapor fractions such as those illustrated by the above tabulation will not be acceptable. It may, however, still be justified to consider VOC condensation as a precursor to a final abatement device such as an adsorption bed. Removing most of the solvent from a vent stream by condensation, can drastically reduce the size and cost of a downstream cleanup system. 

Since SO2 and NO2 are criteria pollutants, their emissions are regulated. In addition, for the purposes of abating acid deposition in the United States, the 1990 Clean Air Act Amendments require that nationwide SO2 and NO emissions be reduced by approximately 10 million and 2 million t/yr, respectively, by the year 2000. Reasons for these reductions are based on concerns which include acidification of lakes and streams, acidification of poorly buffered soils, and acid damage to materials. An additional major concern is that acid deposition is contributing to the die-back of forests at high elevations in the eastern United States and in Europe.

Environmental regulation in the oleochemical industry addresses pollution of air, surface, and groundwater, along with land pollution and soHd waste disposal. This is adrninistered by the Environmental Protection Agency (EPA) on the national level, an equivalent agency on the state level, and sometimes local agencies also deal with various aspects of pollution abatement. 

We begin by reviewing the regulatory driving force in the United States for air pollution abatement. To appreciate the objectives of our Federal air pollution control regulations, an understanding of the fate and transport mechanisms in the environment is important. Hence, some general discussions on the behavior of pollutants in the atmosphere are included in this chapter. 

Also keep in mind that most asbestos abatement is closely monitored by state and local governments. Although OSHA has jurisdiction, the states and local regulators typically keep a watchful eye over ACM activities.

That the authorities have refused unreasonably to accept compliance with alternative requirements or that the requirements of the notice are otherwise unreasonable in character or extent, or are unnecessary. This defense is self-explanatory. The local authorities are only permitted to ask for works that will abate the noise nuisance. Other works (perhaps to comply with legislation) should not be specified in the notice. They may, however, be contained in a letter separate from the notice. An example of this would be where the fitting of acoustic enclosures to food-manufacturing machines breached food hygiene requirements. Readily cleanable enclosures may be a requirement of the Food Hygiene Regulations, but it should not be contained in a Section 58 Control of Pollution Act notice.

Title II - Asbestos Hazard Emergency, Title III - Indoor Radon Abatement, and Title IV - Lead Exposure Reduction, deal with regulation of these specific substances. 

SFE has also replaced many regulated solvents in analytical chemistry applications in recent years, primarily because it provides a more reliable measure of the concentrations of environmental contaminants and can play an important role in pollution assessment, abatement, and control. Advantages have been shown for using SFE compared to the conventional Soxhlet extraction with toluene for determining the presence of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans in ashes from a municipal incinerator (Dolezal et al., 1995). SFE allows the complete extraction of the analytes from the sample, whereas conventional extraction results in an incomplete, and hence, inferior extraction. 

Increasingly stringent environmental regulations imposed on both the military and civilian sectors has created a growing demand for alternative abatement methods for a variety of hazardous compounds. One alternative, the nonthermal plasma, shows promise of providing an efficient means for the destraction of dilute concentrations of hazardous air pollutants. Promising results have been obtained for toluene, methylene chloride, and dichlorodifluoromethane in air at concentrations of a few hundred parts per million. The device has been operated at voltages up to 30 kV, pulse repetition rates up to 1.4 kHz, and flow rates up to 60 1/min (Korzekwa et al., 1998). 

Command-and-control regulation is a rather blunt instrument for achieving an efficient level of public exposure. Its primary defect is its inability to allow emissions to vary across emitters in proportion to their marginal costs of abatement. That inability raises the cost of any specific level of ambient exposure reduction. Empirical analysis of regulatory decisions suggests that agencies are sensitive to the costs and benefits of risk reduction but demand far more reducfion in public exposure risks than individuals require for private risks.
