Current Trends in Federal Interagency Relations Concerning Air Pollution

Under the first Federal Air Pollution Act of 1955, which assigned the responsibility for developing a national program to the Public Health Service, a significant phase of the program involved other federal agencies through a series of contractual relationships. These interdepartmental relationships were limited however, to the objective of capitalizing on the diverse research facilities and specialized competencies within the federal establishment, as a means of accelerating the research and technical assistance program authorized under the act. With the passage of the Clean Air Act of 1963, a major new emphasis has been added to the federal air pollution control program—application of technical knowledge, through broadly accelerated control programs. This emphasis is reflected in current trends in the nature and type of the Public Health Service’s developing relationships with other federal agencies. The emerging PHS programs to prevent and control air pollution from federal facilities, the PHS role in preventing pollution arising from transportation systems aided under the new Urban Mass Transportation Act, and other developing interagency relationships and problem areas are discussed in this context.     

The Law of Federal Air Pollution Control

The Clean Air Act, while recognizing the primary responsibility of states and local governments for the prevention and control of air pollution, provides authority for federal initiative and action to prevent and to abate air pollution which “endangers the health or welfare of any persons.” The applicable statutory procedures and the scope of federal authority are analyzed and discussed.     

Trends in Public Attitudes Toward Air Pollution

This paper attempts to bring together the findings relative to people’s attitudes about air pollution from a series of studies conducted by or for the U. S. Public Health Service. Trends are noted. These findings are presented in the light of planning for the implementation of air pollution abatement measures and probable public reactions to them. Further research needs are pointed out. Special emphasis is placed on the control officer’s needs for this type of information, its derivation, and its possible use in programming.     

Federal Air Pollution Prevention and Abatement Responsibilities and Operations

The direct federal role in air pollution control was expanded and intensified by the 89th Congress to include authority for: (1) abatement of international pollution; (2) promulgation and enforcement of regulations regarding emissions from new motor vehicles and engines; and (8) the conduct cf conferences and formulation of advisory recommendations concerning potential air pollution of substantial significance. Experiences under interstate abatement authorities of the Clean Air Act and plans for future activities under the new authorities are discussed.     

A Canadian Federal Viewpoint on the Regulatory Process for Air Pollution Control

The following remarks are excerpted from an address presented by Mr. Rivers on October 7, 1980 to the 4th annual meeting of the Atlantic Canada Chapter of APCA's Northeast Atlantic International Section.     

State and Community Reactions to the Federal Air Pollution Program

The Federal Air Pollution Program is growing rapidly. Its activities are affecting state and local programs both directly and indirectly. Some of these activities are discussed and suggestions are made for developing closer cooperation in the areas of program grants, motor vehicle emission control, Federal abatement procedures, and technical assistance.     

Federal Activity in Developing Air Quality Criteria

The author will describe the program of the Division of Air Pollution for developing air quality criteria and the present state of preparation of documents covering criteria for two broad classes of contaminants—the oxides of sulfur and photochemical oxidants. The preparation and content of these documents are briefly reported.

Abstract

Computational fluid dynamic (CFD) analysis of the thermal flow in the combustion chamber of a solid waste incinerator provides crucial insight into the incinerator’s performance. However, the interrelation of the gas flow with the burning waste has not been adequately treated in many CFD models. A strategy for a combined simulation of the waste combustion and the gas flow in the furnace is introduced here. When coupled with CFD, a model of the waste combustion in the bed provides the inlet conditions for the gas flow field and receives the radiative heat flux onto the bed from the furnace wall and gaseous species. An unsteady one-dimensional bed model was used for the test simulation, in which the moving bed was treated as a packed bed of homogeneous fuel particles. The simulation results show the physical processes of the waste combustion and its interaction with the gas flow for various operational parameters.     

Careers in Air Pollution Control

Abstract

The destruction of parts per million (ppm) levels of volatile organic compounds in a dry air stream by high–energy electron–beam irradiation has been investigated in a pilot plant at the University of Tennessee Space Institute, Tullahoma, Tennessee. In a series of experiments, dry air contaminated with various VOCs in the concentration range of 50–1000 ppm were treated in the UTSI pilot plant to determine the extent of destruction at various electronbeam dose levels.

The destruction removal efficiency was determined as a function of the electron beam irradiation dose. The results suggest a charge transfer reaction as the major decomposition mechanism. A theoretical foundation of the process, along with a simple first–generation reaction kinetics model, a summary of the results from the pilot plant flow reactor, and a preliminary cost analysis for a fullscale detoxification plant using currently available electronbeam gun technology are presented in this paper.     

Air Pollution and Health

The use of multistage, dry, fluidized beds of continuously recycled, coal-based activated carbon appears technically and economically attractive for both adsorption of stack gas So₂ and sequential conversion to elemental sulfur. Conceptual design details and economic factors are discussed for the treatment of power plant or oil refinery SO₂ effluents with by-product sulfur recovery.     

Air Pollution Research Problems

The TR-l Research Committee of the Air Pollution Control Association conducted a survey during 1969–70 to determine what air pollution research problems require attention. All APCA committees were requested to contribute topics to this survey, especially within their area of activity. Other professional societies were contacted through liaison representatives of APCA. The responses to the survey have been reviewed, categorized, selected, and edited for inclusion in this report. Additional material and concepts have been contributed by members of the TR-l Committee.     

Air Monitoring Reflects Air Pollution Control Activity

Air monitoring by the A.I.S.I. filter sampling device which both preceded and was concurrent with source control of particulates demonstrated air quality improvement over a ten-year period. A difference in improvement from that estimated by the pollution control agency resulted from difference in the measurement parameters.
