Air Resource Management in the Chicago Metropolitan Area

This paper discusses the approach used by the City of Chicago to encourage the implementation of an air resource management program in the metropolitan area. It explores the many facets that were helpful in designing and implementing the City of Chicago’s Five-Year Air Resource Management Program and the progress to date. Also highlighted is the social geography of the metropolitan area and the relationship of population growth and rapid industrial expansion to the area’s air pollution problem. Existing control programs in the Chicago Metropolitan Area are reviewed and are used to document the various elements essential for the success of an air resource management program. These include the Chicago Program, the Cook County Program, the State of Illinois Program and the Interstate Program between Illinois and Indiana. The authors devote considerable discussion to the methodology used to develop an air resource management program, including selection of goals, design of organization, technical development, definition of sources and effects, systems approach, and long- and short-range objectives. The importance of a public information and education program and its relationship to various segments of community leadership are also covered in this paper     

Inventory of Emission for the City of Chicago

A review of the methodology used in the development and implementation of a comprehensive emission inventory survey with emphasis on manufacturing plants. This inventory, a major goal in the Dynamic Air Resource Management Program for the City of Chicago, is a principal objective of a Five-Year Technical Assistance Agreement with the United States Public Health Service, Division of Air Pollution and Chicago’s Department of Air Pollution Control. Information obtained through a 75 percent response from a questionnaire mailed to 7312 manufacturing firms provided the basis for this inventory. Data on the delinquent firms was obtained from on-site evaluation by department engineers. This report will also cover computer processing and tabulation of survey data.     

Citizen Complaints of Air Pollution In Northeastern Illinois

In 1964, as part of the Northeastern Illinois Metropolitan Planning Commission's Air Resource Management Study, an examination was made of citizen complaints of air pollution registered with air pollution control agencies representing the City of Chicago, outlying Cook County, and the State of Illinois. The complaint files of the City of Chicago were found to contain the addresses of some 9500 air pollution sources specified by complainants in complaints covering the time period from approximately 1954 to 1964. A statistical sample of these sources showed more than 70% to be of a nonindustrial nature, with domestic fuel burning or incineration by neighbors most often specified. There were 1119 industrial process source snamed in the Chicago files; 588 nonmanufacturing and 531 manufacturing. Fabricated metal industries, primary metal industries, chemical manufacturers, and food processing plants were cited more often than other industrial categories. Complaint sources named in complaints filed by citizens with the State of Illinois, and with Cook County, differed with those of Chicago in that industrial sources were specified more often than nonindustrial ones. The reason for this is believed to lie in the reduced residential densities and the relatively great use of pollution-free fuels in the metropolitan area outside of the City of Chicago.     

Introduction to the Air & Waste Management Association's 30th Annual Critical Review

This marks the 30th year of the Air & Waste Management Association's Critical Review Program. The Critical Review is a feature of A&WMA's Annual Conference, and is directed by the Critical Review Committee. The committee evaluates several topics each year, selects the best for presentation, and invites an individual (or group) to prepare the Critical Review Paper. This paper is thoroughly reviewed by the committee members and a panel of experts. After presentation of the review by the authors (typically on the Wednesday of the Annual Conference), there is a panel discussion and question-and-answer session. Panel members are invited to prepare their comments on the Critical Review, which, along with audience comments and the author's closing statements, are published in the Journal.     

Complying with Executive Order 13148 using the Enterprise Environmental Safety And Occupational Health Management Information System

All U.S. Department of Defense (DoD) facilities are required under Executive Order (EO) 13148, "Greening the Government through Leadership in Environmental Management," to establish quality-based environmental management systems (EMSs) that support environmental decision-making and verification of continuous environmental improvement by December 31, 2005. Compliance with EO 13148 as well as other federal, state, and local environmental regulations places a significant information management burden on DoD facilities. Cost-effective management of environmental data compels DoD facilities to establish robust database systems that not only address the complex and multifaceted environmental monitoring, record-keeping, and reporting requirements demanded by these rules but enable environmental management decision-makers to gauge improvements in environmental performance. The Enterprise Environmental Safety and Occupational Health Management Information System (EESOH-MIS) is a new electronic database developed by the U.S. Air Force to manage both the data needs associated with regulatory compliance programs across its facilities as well as the non-regulatory environmental information that supports installation business practices. The U.S. Air Force, which has adopted the Plan-Do-Check-Act methodology as the EMS standard that it will employ to address EO 13148 requirements.     

Air Pollution in Six Major U. S. Cities as Measured by the Continuous Air Monitoring Program

Data obtained by the Continuous Air Monitoring Program (CAMP) in six cities during two years are summarized. Six gaseous pollutants were monitored in Cincinnati, Chicago, New Orleans, Philadelphia, San Francisco, and Washington, D. C. during 1962 and 1963. The data serve as a basis for describing several contrasts and similarities in the nature of air pollution experienced in six cities, which represent a broad geographical and climatological range of urbayi environments. Specific topics covered are: typical pollutant levels, patterns of daily and seasonal variations, and unusual phenomena such as atmospheric stagnation periods and photochemical smog formation.     

A Dynamic Air Resource Management Program,City of Chicago

A review of air pollution control activities since 1881, and the current needs to change from a smoke abatement to an air resource management program are presented. The rapid and dynamic transition made by the City of Chicago since 1962 in its air pollution control activities are explored in terms of organizational changes, training of professional and nonprofessional personnel, ambient air quality measurements, emission inventory of commercial and industrial operations directed toward issuance of certificates of operation, evaluation of health effects and materials damage, modifications to the municipal code, and the interrelationship of air pollution control activities with urban planning and the regional complex. The multidiscipline Public Health Service, Division of Air Pollution, Technical Assistance program initiated in October 1962, and planned for a period of five years, is discussed. The achievements, particularly since 1962, in the many faceted Chicago air resource management program together with some of its longrange plans are delineated.     

The New England Air Quality Forecasting Pilot Program: development of an evaluation protocol and performance benchmark

The National Oceanic and Atmospheric Administration recently sponsored the New England Forecasting Pilot Program to serve as a "test bed" for chemical forecasting by providing all of the elements of a National Air Quality Forecasting System, including the development and implementation of an evaluation protocol. This Pilot Program enlisted three regional-scale air quality models, serving as prototypes, to forecast ozone (O3) concentrations across the northeastern United States during the summer of 2002. A suite of statistical metrics was identified as part of the protocol that facilitated evaluation of both discrete forecasts (observed versus modeled concentrations) and categorical forecasts (observed versus modeled exceedances/nonexceedances) for both the maximum 1-hr (125 ppb) and 8-hr (85 ppb) forecasts produced by each of the models. Implementation of the evaluation protocol took place during a 25-day period (August 5-29), utilizing hourly O3 concentration data obtained from over 450 monitors from the U.S. Environment Protection Agency's Air Quality System network.

Defining the photochemical contribution to particulate matter in urban areas using time-series analysis

The objective of this project is to demonstrate how the ambient air measurement record can be used to define the relationship between O3 (as a surrogate for photochemistry) and secondary particulate matter (PM) in urban air. The approach used is to develop a time-series transfer-function model describing the daily PM10 (PM with less than 10 microm aerodynamic diameter) concentration as a function of lagged PM and current and lagged O3, NO or NO2, CO, and SO2. Approximately 3 years of daily average PM10, daily maximum 8-hr average O3 and CO, daily 24-hr average SO2 and NO2, and daily 6:00 a.m.-9:00 a.m. average NO from the Aerometric Information Retrieval System (AIRS) air quality subsystem are used for this analysis. Urban areas modeled are Chicago, IL; Los Angeles, CA; Phoenix, AZ; Philadelphia, PA; Sacramento, CA; and Detroit, MI. Time-series analysis identified significant autocorrelation in the O3, PM10, NO, NO2, CO, and SO2 series. Cross correlations between PM10 (dependent variable) and gaseous pollutants (independent variables) show that all of the gases are significantly correlated with PM10 and that O3 is also significantly correlated lagged up to two previous days. Once a transfer-function model of current PM10 is defined for an urban location, the effect of an O3-control strategy on PM concentrations is estimated by calculating daily PM10 concentrations with reduced O3 concentrations. Forecasted summertime PM10 reductions resulting from a 5 percent decrease in ambient O3 range from 1.2 microg/m3 (3.03%) in Chicago to 3.9 microg/m3 (7.65%) in Phoenix.     

Computer estimation of the Atmospheric gas-phase reaction rate of organic compounds with hydroxyl radicals and ozone

The Atmospheric Oxidation Program (AOP) is a computer program that estimates the rate constant for the atmospheric, gas-phase reaction between photochemically produced hydroxyl radicals (OH) and organic chemicals. It also estimates the rate constant for the gas-phase reaction between ozone and olefinic/acetylenic compounds. AOP, which uses estimation methods developed by Atkinson and co-workers, estimates more accurate rate constants than the PCFAP (Fate of Atmospheric Pollutants) program that was part of the U.S. EPA's Graphical Exposure Modeling System (GEMS). Due to its superior predictive ability, the EPA is currently using AOP to evaluate the atmospheric fate of compounds defined under Sections 4, 5 and 6 of the Toxic Substances Control Act (TSCA).

Day-of-Week behavior of atmospheric ozone in three U.S. cities

The weekly cycles of atmospheric ozone (O3) are of interest because they provide information about the response of O3 to changes in anthropogenic emissions from weekdays to weekends. The weekly behavior of O3 in Chicago, IL; Philadelphia, PA; and Atlanta, GA, is contrasted. In Chicago and Philadelphia, maximum 1-hr average O3 increases on weekends. In Atlanta, O3 builds up from Mondays to Fridays and declines during weekends. In all three areas, volatile organic compound (VOC)/nitrogen oxides (NOx) ratios are higher during weekends, resulting from greater than proportionate decreases in NOx relative to VOC emissions. The VOC/NOx ratios correlate with maximum 1-hr O3 concentrations in Chicago, a response consistent with a VOC-sensitive airshed. A weak correlation between O3 concentrations and VOC/NOx ratios in Philadelphia suggests the impact of transported O3, which is formed in upwind VOC-sensitive locations that may be hundreds of kilometers away. Ozone concentrations in Atlanta do not correlate with VOC/NOx ratios but with concentrations of NOx and total reactive nitrogen (NOy) carried over from the previous day. When data from 1986-1990 and 1995-1999 are compared, only small differences in the weekly behavior of O3 are observed in Chicago and Philadelphia. The day-of-week differences in O3 are amplified in the more recent period in Atlanta, a possible result of urban growth.     

Mercury Concentration in the Atmosphere in Chicago A New Ultrasensitive Method Employing Amalgamation

During the past two years, the Chicago Department of Environmental Control chemistry laboratory has developed a prototype sensor for measuring low levels of mercury found in the free or ambient atmosphere. Earlier studies of mercury in the Chicago area postulated that most of the mercury in the atmosphere should condense onto particulates and be collectable on filters. The results of the work presented here show that this may not occur. Analysis of composites of Chicago high volume particulate filters results in an average of 4 nanograms/m³ (range 2-10 nanograms/m³). This compared with a typical average of elemental mercury measurements of 22 nanograms/m³ (range 5-60 nanograms/m³). Thus, it is obvious that particulate borne mercury, at least as analyzed from a high volume filter paper, is not as significant as the total or elemental mercury existing in the metropolitan area. A direct method for collecting mercury and measuring in a flameless atomic absorption unit yields very good results.     

Walkerton: requiem for the New Public Management in Ontario?

In May 2000, seven residents of Walkerton, Ontario, died, and hundreds more became seriously ill as a result of the contamination of the town's water supply. Immediately, residents and environmental activists pointed to the weakening of the province's environment ministry as the principal cause. Since coming to power in 1995, the Progressive Conservatives had taken steps to privatise and deregulate a number of public services, which are two policy instruments of the New Public Management (NPM). Drawing on the conclusions of the inquiry into the underlying causes of the water contamination, this article suggests that Walkerton is not the knock-out punch for NPM that many had predicted.
