A Successful and Productive Year

It is gratifying to report that 1975-1976 has been another year of increased activity for the Air Pollution Control Association, and various indicators are positive compared to previous years. Membership has increased, attendance at meetings has increased, we have a substantial surplus to report, there is increased activity in membership interest and in our overall activity. Public affairs involvement has increased somewhat, as have our international activities. Local sections and technical committees have expanded their scope of productive involvement. Clearly, APCA has had a successful and productive year.     

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.     

long Term Goals for Environmental Control— What’s Desirable and Possible in the Year 2000?

A panel discussion looking forward to the environment in the year 2000, was arranged by Lionel V. Baldwin, Program Chairman for APCA’s 67th Annual Meeting. To provide a lofty introduction of the subject he reached into outer space for a moderator—Captain Walter M. Schirra, one of the original astronaut team.     

“The Clean Air Act — A Time for Evaluation”

The Third Government Affairs Seminar sponsored by the Air Pollution Control Association was held in Washington, D. C. on April 16-17, 1975. The APCA South Atlantic Section was host for this very successful meeting. The General Chairman of the Seminar Committee was John V. Brink and the Program Chairman was Richard D. Grundy.

The seminar this year was conducted in three sessions. The first session, entitled “The Clean Air Act: State vs Federal Roles,” considered a topic that is receiving increasing emphasis as the national air pollution control program matures. This discussion was chaired by M. Barry Meyer, Chief Counsel and Chief Clerk, Senate Committee on Public Works.

The second session was “Land Use Planning Aspects of the Clean Air Act—Federal, State and Regional Roles.” Mrs. Mary Jane Due, Chairman of the Public Land and Land Use Committee, Natural Resources Section, American Bar Association, served as Moderator of this discussion of indirect source regulations, no significant deterioration, air quality maintenance—concepts that rely heavily on comprehensive land use planning.

“Clean Air Priorities—The Need for Flexibility,” was the title of the third session which was chaired by Austin H. Phelps, Manager Corporate Air Pollution Control, Procter and Gamble Company and President of APCA. The panelists considered the question of how appropriate the standard setting mechanisms of the Clean Air Act are for the resolution of present and future problems.

In this report condensed versions of the prepared statements of the participants are presented. A more extensive summary of the Proceedings, which includes questions and answers, is available from APCA headquarters. The remarks of John R. Quarles, EPA Deputy Administrator, who was the luncheon speaker, were summarized in the June APCA Journal(p. 642).     

The Bag Filterhouse for Oil-Fired Power Plants

This Report, published as Informative Report No. 7 of the Air Pollution Control Association’s TI-5 Public Utilities Committee, began to move through the 14 step approval procedure of APCA’s Technical Council in February 1964 Comments made by members of the Technical Council were considered in the preparation of the final report. It is now published as representing the best thinking of the Association. It is an extremely timely and informative report.     

Honorary Memberships

Honorary Memberships are conferred by the Air Pollution Control Association on persons of widely recognized eminence in some part of the field of air pollution control or who have rendered especially meritorious service to the Association. Honorary Memberships were awarded this year to Dr. Leonard Greenburg and Mr. Milton Reizenstein, both past presidents of APCA.     

Removal of Exhaust Odors from Solvent Extraction Operation by Activated Charcoal Adsorption

This report, published as Technical Data Sheet No. 1 of the Air Pollution Control Association’s TA-7 Odor and Gas Treatment Committee, has been in the 14 step approval procedure of APCA’s Technical Council and Board of Directors for over two years. The Committee is attempting a new departure in this report which would be reflected in future reports. It has attempted to write a brief summary of a typical case history in a concise fashion on one sheet. Comments made by members of the Technical Council and Board of Directors were considered in the preparation of the final report. It is now published as representing the “best thinking of the Association.”     

“Let’s knock off the slogans and concentrate on the work”

In preparing for this address, I went back and read the Presidential Addresses given by the last six presidents. For a while, I toyed with the idea of cutting and pasting bits and pieces out of each, adding a few appendices, having it published in the Journal with ninety days for comment, and calling it an “implementation speech.” But I passed up that opportunity. I did note that Presidential Addresses come in a limited variety of styles. There is the one whose theme is “serving you as President has been a period of great personal satisfaction and pride.” There is the one that refers to all the things that happened in APCA during the year of the term with suggestions for what should happen in the next few years, or the State of the Association speech. There is the speech that deplores and decries something about the Clean Air Act or the way air pollution control is going in the country, or the way it should go. And of course, there is the simple exhortation for us all to pull together and clean up the atmosphere for future generations, the APCA Statesman speech. None of those fit my mood.     

Looking Forward: Concerned but Confident

Each outgoing president of APCA is required to present a report to the Board of Directors at the last meeting of the Board over which he presides. By custom this report is in two parts, one summarizing the highlights of the year of his presidency, the other offering his forecast and recommendations concerning the future of the association. I have chosen to base my presidential address today on an expansion of my forecast and recommendations.     

Certification Programs in Air Pollution Control

When the questionnaire form for Consultant Guide/1972 was published in the APCA Journal early this year, it included space for an indication of any certifications granted to a consultant by the three Boards which have established standards for professional activity in the field of air pollution control. The editorial staff, well aware of these Boards, was surprised at the number of requests received by phone and mail for information concerning the certification programs. In response to these requests we are publishing on the following three pages invited statements from principals of the three Boards outlining the procedures involved in applying for professional certification.     

Ozone Air Quality Models Prepared Discussion

The APCA Critical Review entitled “Ozone Air Quality Models” was presented by John H. Seinfeld, Louis E. Nohl Professor and Executive Officer for Chemical Engineering at the California Institute of Technology, Pasadena, California. Dr. Seinfeld presented his review at the 81st APCA Annual Meeting & Exhibition, held in Dallas, Texas in June 1988. The Critical Review paper, published in the May 1988 issue of JAPCA, highlighted recent advances and continuing problem areas in photochemical air quality modeling. Prepared discussions and floor comments presented during the Critical Review session in Dallas are published here, along with additional comments and closing remarks by Dr. Seinfeld. Howard M. Ellis, Chairman of the Critical Review Subcommittee of the Publications Committee, served as moderator of the 1988 APCA Critical Review session.     

Absolute principal component analysis of atmospheric aerosols in Mexico city

A receptor model is presented based on absolute principal component analysis (APCA) of elemental concentrations in atmospheric aerosols from Mexico City during the Summer of 1995. Elemental contents on samples collected with a Stacking Filter Unit of the Davis design was carried out using Particle Induced X-ray Emission (PIXE). The sampling device allowed the separation of particles with mean aerodynamic diameters ranging from 2.5 μm to 15 μm (coarse fraction) and smaller than 2.5 μm (fine fraction). Sampling was divided into morning, afternoon and night periods, with higher concentrations being found during the morning. Seasonal variation is observed when comparisons with other studies are carried out. The application of APCA allowed identification of four sources for each fraction, with a soil-derived dust predominance in the coarse one. The influence of meteorological parameters is studied using cluster analysis, showing that during the morning there is a transport of pollutants from the west towards the sampling site, while the night transport corresponds to soil-derived dust from the north.

The Keynote Address of APCA’s 66th annual meeting was delivered by Bert S. Cross, a director of the 3M Company, St. Paul, Minn., and former chairman of the National Industrial Pollution Control Council.     

Air Pollution Aspects of Soap and Detergent Manufacture

Informative Report No. 8 on soap and detergent manufacture is one of a series of survey reports prepared by APCA’s Tl-2 Committee on air pollution problems and control methods encountered in the chemical industry today.     

Summary of am APCA International Specialty Conference

Ozone continues to be one of the most important air pollution problems in the United States. While significant progress has been made, certain areas of the country still experience unhealthy levels of ozone and are unlikely to achieve current primary standards by 1988. With the prospect of an influx of millions of additional people, and their cars, into these areas by the year 2000, the problem of oxidant regulation and control becomes even greater. From this realization, the Effects Division of the Air Pollution Control Association conceived this conference topic. The summary that follows highlights key issues and findings from the conference held in November 1984 in Houston, Texas. The transactions of the conference will be available from APCA headquarters in the near future.     

Trends in Emissions of PM,SO x and NO X,and VOC:NO X Ratios and Their Implications for Trends in pH near Industrialized Areas

The following address was presented by Mr. Costle on June 23 at the opening plenary session of the 73rd APCA Annual Meeting and Exhibition in Montreal.     

Incineration of Hazardous Waste

The APCA Critical Review entitled "Incineration of Hazardous Waste" was presented by E. Timothy Oppelt, Chief, Thermal Destruction Branch, Alternative Technologies Division of U.S. EPA’s Hazardous Waste Engineering Research Laboratory (Cincinnati). Mr. Oppelt presented his review at the 80th APCA Annual Meeting & Exhibition, held in New York City in June 1987. The Critical Review paper, published in the May 1987 issue of JAPCA, examined the current state of knowledge regarding hazardous waste incineration in an effort to put the technical and environmental issues into perspective. Prepared discussions presented during the Critical Review session are published here, along with additional comments and closing remarks by Mr. Oppelt. Howard M. Ellis, Chairman of the Critical Review Subcommittee of the Publications Committee, served as moderator of the 1987 Critical Review session.     

Electrostatic Precipitator Maintenance Survey

In the latter part of 1974, the TC-1 Committee of the APCA undertook a survey of four (4) major user industries of electrostatic pre-cipitators. The purpose of the survey was to establish the users’ degree of satisfaction with this equipment from an operational and a maintenance viewpoint. Specific areas of maintenance requirements were investigated as well as the nature of difficulty experienced. The 174 responses received covered user experience with 243 precipi-tators of various manufacturers. This paper reports on the results of this survey and gives the statistics derived. The conclusions reached should be beneficial to the user and the manufacturer in the areas of product improvement and maintenance.

This is the first of this type of survey handled by the TC-1 Committee, and it will be followed by Fabric Filter and Scrubber information gathering questionnaires. Problem areas so defined will be enlarged upon in future seminars planned under APCA auspices.     

Determining the Costs of Air Pollution Control

A general procedure has been described that can be followed for estimating the cost of reducing air pollution emissions within a metropolitan region. The six step procedure examines emission inventories, regional trends, control trends, alternate control schemes, control costs, and optimum cost-effectiveness. The procedure is illustrated for one emission source in the Delaware Valley. By application of “feasible controls,” automobile emissions were shown to be reduced from 4.5 billion pounds per year in the Region during 1968 to 1.5 billion pounds in the year 2000. Annual control costs during the same period will increase from $30 million to over $300 million per year. This represents a cost increase from $15 per registered vehicle in 1968 to about $58 per vehicle per year in 2000. A method was illustrated for determining minimum cost to achieve any desired degree of emission reduction where alternate feasible control schemes are available. This method is especially useful where the allocation of scarce resources is involved. The general procedure is applicable to any number of pollutants and emission sources, and may be useful for calculations in any metropolitan area. The objectives of the present study are to apply this method to other sources within the Delaware Valley and to determine total regional costs for various levels of emission reduction. As one example of a practical application for this type of analysis, the economic impact of regulatory schemes can be evaluated on a cost-effectiveness basis
