Hoffnagle, CCM Proposal Number 8612-P51-38 DR5901026 1.0 INTRODUCTION The United States Environmental Protection Agency (EPA) is reviewing the National Ambient Air Quality Standard (NAAQS) for lead. EPA is considering reducing NAAQS in order to provide increased protection to children exposed to lead around point sources, i.e., primary and secondary smelters, refineries and battery plants. This emphasis on point sources follows from the lead in gasoline phaseout which has already brought general lead ambient air quality below quarterly averages of 0.5 yig/m3. EPA has provided a draft criteria document {EPA-600/8-83/028C) and a staff paper (OAQPS, Feb. 1986) which evaluate reductions of the NAAQS from a quarterly average concentration of 1.5 pg/m3 to a monthly average of 1.0 or 0.5 pg/m3. These were presented to the Clean Air Science Advisory Committee (CASAC) in March 1986 and LIA presented testimony, supported by TRC Environmental Consultants. The modeling of lead exposure to children presented in the EPA documents demonstrated clearly that exposure through the air pathway is a minor fraction of total exposure. This blood lead modeling even ignored exposure from lead-based paint and increased blood lead exposure in economically disadvantaged populations. Because the air pathway is a small portion of the exposure, meeting blood lead objectives would require substantial reductions in air lead concentrations. Because of the single media focus of the NAAQS process, the only option available to EPA's Office of Air Quality Planning and Standards (OAQPS) and to CASAC is to revise 'the NAAQS. CASAC did discuss, in March 1986, the possibility of changing lead from a NAAQS to a National Emission Standards for Hazardous Air Pollutants (NESHAP) pollutant. Such a change is within the jurisdiction of OAQPS and has the advantage of considering economics, which the NAAQS does not, and more flexibility for alternative approaches. LIA might pursue such a strategy on the air side of EPA. NESHAP has the disadvantages of being labeled -1- "hazardous" and the potential of source-by-source emission limitations rather than meeting just fenceline concentrations. At the same time, other portions of EPA are dealing with lead exposure in their own separate media. The Office of Drinking Water is revising its standards to further reduce blood lead and the Superfund program is following the example of Dallas in pressing for lead in soil standards in clean up requirements. Each of these programs is attacking the same issue, blood lead concentrations in children. In each case, the agency seeks to meet the target blood lead concentration through control of a single medium of exposure. At the same time other media with sometimes more important exposures are ignored, e.g. lead in paint, tracked-in dirt, etc. It is clear, however, that more direct control of exposures, directed at the children involved, is a viable alternative. Such an alternative could more effectively provide health protection and would not require clean-up through each media well beyond the requirements for such protection. This proposal seeks to provide the technical basis for the development of such an alternative and to prepare appropriate documentation for the presentation of the alternative. TRC will also assist in preparing the exact language of the alternative as needed by the Lead Industries Association. Section 2 of this proposal presents the scope of work and Section 3 provides a cost proposal. Section 4 provides the Resumes of TRC assigned personnel. -2- 2.0 SCOPE OF WORK The scope-of-work has been organized into identifiable tasks which meet the objectives of the Lead Industries Association for a clear exposition of the technical support for an alternative method of controlling exposure to lead. 2.1 Task 1 - Literature and Data Acquisition TRC will identify, obtain, codify and summarize environmental standards for lead in all media. The search will include all countries and jurisdictions. Care will be taken to include labor and health standards in addition to environmental requirements. Special emphasis will be placed on multi-media approaches where those exist. TRC will also identify, obtain and summarize all studies of blood lead related to point sources. Many of the studies are already in TRC's possession, but it is important to insure that other studies in the literature do not contradict the results of those relied upon here. For each of the major studies an attempt will be made to gather any unpublished data and, with carefully prepared questions, talk to the researchers/writers involved about specific details on which to base a firmer understanding of their work. The true nature of each child' s exposure is often masked in average data and an attempt will be made to discover true exposure sources. 2.2 Task 2 - Exposure Assessment The relative importance of children's exposure to lead is the most difficult of the data requirements in any model of blood lead. The best data on which to base the relative importance of various pathways is field experience. Cleanup programs have valuable data on changes in some lead exposures which result in changes in children's blood-lead. Canada Metals, -3- DR5901029 RSR and Dixie Metals have undertaken cleanup of household dust, yard soil and changes in ambient coneentration. The effect, in terms of blood-lead, on the exposed children will be documented and evaluated to determine: The independent rate of blood-lead reduction obtained with each type of cleanup. The cumulative rate of blood-lead reduction obtained with multiple clean-up approaches. The threshold or limit, if any, to the effectiveness of the clean-up approach. Whether limited area cleanup, e.g., yard and house, is effective at maintaining reduced blood-lead concentrations in light of the potential for redeposition of lead in the cleaned areas. Each of the investigations undertaken will seek to provide more accurate input data for the EPA child lead absorption model. Discovering in real world situations which pathways of exposure are most important and which controls present the best response in terms of blood-lead will aid this effort. 2.3 Task 3 - Model Re-evaluations EPA's child lead absorption model was presented in the criteria document as one of three theoretical choices of models. It was selected from the three since it makes the clearest demarcation between the various pathways. Re-evaluation of the model results should now be made with real world data (EPA presented only theoretical results using average or assumed input data). The model has been evaluated using data from Herculaneum. That modeling should be refined and supplemented by model exercises from Kellogg and East Helena. In addition, TRC will review the potential for modeling at other sites. Pre- and post- cleanup or source shut-down modeling would be very instructive at any of these sites. The objective of the modeling effort will be to: 1) test the validity of the model as a predictive tool, 2) determine -4- DR5b01030 any valid change which could be made to the model or its assumptions and 3) demonstrate the ability of the model to estimate cleanup consequences. 2.4 Task 4 - Control Methodology Development Given the importance of various pathways of exposure and the blood-lead results in the example cleanups, a consistent and broadly applicable control methodology will be developed. TRC will work closely with the LIA committee in developing the test strategy. The test strategy will be run on the model to determine the blood-lead results which can be expected. The sensitivity of the results to items like exact soil lead concentration and recontamination, etc. will be tested. Once a control strategy is finalized, the costs of the control strategy will be assessed and presented along with control costs of other strategies, i. e. , air emissions control from the TRC study, costs of total area soil cleanups such as those in Dallas, etc. It should be noted that strategies may differ slightly from site-to-site given differences in climate, etc. This study will, however, be providing a throughly tested model with which to make control decisions at individual sites if a more generic result cannot be put forward. 2.5Task 5 - Final Report and Presentation TRC will be preparing a final report on its findings for the review of the LIA committee and revise the report as necessary given the committee comments. TRC will also be prepared to present the results of its findings to CASAC, headquarters EPA, OMB or any other appropriate forum as directed by the committee. -5- DR5931931 3.0 PROJECT MANAGEMENT AND COSTS TRC proposes to provide Gale F. Hoffnagle, CCM, Vice President and Technical Director, as its project manager. Mr. Hoffnagle has worked with the LIA on previous efforts as well as having years of experience working for lead industry companies on lead contamination issues. Mr. Hoffnagle has provided testimony to CASAC and to EPA regulatory hearings over the years most recently on lead, for LIA, and particulate matter, for AMC. Assisting Mr. Hoffnagle on the health exposure analyses will be Jim Kawecki, manager of TRC's Washington, D.C. office. Mr. Kawecki has been involved in the development and criticism of criteria documents throughout his career. He provides valuable insight into the most effective avenues of identifying and presenting data and results to CASAC and others. Dr. Sharon McCarthy will also provide extremely valuable assistance in risk assessment procedures and exposure methodologies. Assisting on the technical side will be Dr. Richard DeCesar whose expertise in lead pathways and control of particulate lead comes from his years at NEA, Inc. where one of his project assignments was Bunker Hill. Also providing assistance will be Bradley Reynolds who, prior to joining TRC, provided SIP technical development for lead while at the Missouri Department of Natural Resources and whose technical background is directed toward resuspension of lead dust. Mrs. Inka Peczerski, TRC Librarian, will provide literature and standards search services. TRC recognizes the urgency of the project in view of the preliminary scheduling of a CASAC meeting in March 1987. TRC proposes to have the draft report available for the LIA Committee by mid-February and a final ready prior to the meeting. As before, changes and enhancement can be provided after the meeting of CASAC up to the comment deadline, thus providing some flexibility -6- OR5901M92 in exact approach. The greatest point of effectiveness, however, is in the meeting itself.

HOFFNAGLE, CCM PRINCIPAL CONSULTING METEOROLOGIST EXPERTISE: Expert Testimony, Dispersion Modeling, Air Quality Meteorology, Fugitive Dust, Acidic Deposition, Toxic Air Pollutants SUMMARY OF EXPERIENCE Mr, Hoffnagle, a Vice President and Principal Consulting Meterologist, has over 14 years of air quality meteorology and modeling experience providing consulting services to industrial clients across many industrial categories and in every region of the country. He provides the technology and experience to solve complicated meteorological and regulatory problems from conceptual design of regulatory approach, model methodology, comparison to existing air quality data, regulatory interface and negotiations, and report preparation to the expert testimony to defend meteorological evaluations. He has carried projects through all these steps for such diverse situations as a coal-fired power plant in New Mexico, a copper smelter in Texas, a refinery in Louisiana, a lead smelter in Missouri, a coal-fired power plant in Pennsylvania, and a coal conversion project in New York. Several of these projects involved complex terrain meteorology and modeling in which Mr. Hoffnagle has considerable experience and a nationwide reputation. Other projects concentrated on particulate deposition modeling, multiple source urban area modeling, and aerodynamic downwash evaluations. Mr. Hoffnagle has served as a consultant to the American Petroleum Institute, the utilities of Colorado, the American Mining Congress, the Houston Chamber of Commerce, and the Utility Air Regulatory Group. His prior employment includes Environmental Research and Technology, Intera Environmental Consultants, and the U.S. Air Force Environmental Health Laboratory.

KAWECKI PRINCIPAL POLICY CONSULTANT EXPERTISE: Health and Risk Assessment, Toxicology, Environmental Chemistry SUMMARY OF EXPERIENCE James M. Kawecki, a Principal Policy Consultant at TRC, has fifteen years experience in environmental chemistry and ttfxicology. A former appointee to the U.S. EPA's Office of Standards and Regulations, Jim was involved with issues relating to the development of methodologies for assessing risk, "red border review" for criteria pollutant regulations, the Regulatory Agenda, and the incorporation of a "plain English" policy within the Agency, under Executive Order 12044. In addition to conducting numerous health assessments for multi-media pollutant exposures, he has focused on generic issues related to risk assessments. As part of EPA's Project ATLAS, he headed a team of multidisciplinary researchers to devise innovative methods for determining the potential risks to public health from hazardous waste sites. His two year association with the Love Canal assessments provided the testing ground for evaluating these techniques. More recently, he has been involved in developing new approaches to refining risk assessment methodologies. Some of this work includes studies to determine the severity (or implications) of specific health endpoints, approaches to assessing risk from chemical mixtures, and ways to increase the confidence in the risk assessment results through probabilistic determinants. As a seasoned writer, Mr. Kawecki's journalistic interests in science reporting has led to his involvement with the issue of how science is interpreted and presented in the popular media, that is, how science is transferred from the laboratory to the living room. As the former director of health and environmental research for a large Washington-based consulting firm, Mr. Kawecki had hands-on involvement in the development of new medical technologies, where he was a member of the Board of the Directors of the Johns Hopkins University joint venture to develop a microbiological identification instrument. This instrumentation was a modification of his company's life-detection system on Mars and also played in the development of the so-called "left-handed" sugars. Accordingly, Mr. Kawecki offers the breadth and depth of experience to assist on all phases of project leadership, management, design, and development.

MCCARTHY, Ph.D. SENIOR ENVIRONMENTAL HEALTH SCIENTIST EXPERTISE; Indoor Air Quality, Statistics, Health Effects of Environmental Pollutants, Epidemiology SUMMARY OF EXPERIENCE Dr. McCarthy has 10 years experience in indoor and outdoor air quality monitoring, exposure assessment, health effects of air pollutants, and statistical analysis of air quality and exposure data. This experience was gained in work for the U.S. Environmenta 1 Protection Agency, Environmental Research and Technology, Inc., and at the Harvard School of Public Health. Her Ph.D. dissertation at the University of California was on the elemental characterization of indoor and outdoor aerosols. Multivariate statistical analyses were used to identify source contributions to aerosols and to model the relationship between indoor and outdoor aerosols. While completing her Ph.D. she took several courses in physiology and environmental toxicology. At TRC, Dr. McCarthy is involved in a variety of projects relating to risk assessment, indoor air quality, and statistical analyses of environmental quality data. A recent project involved the evaluation of the literature on various indoor air pollutants for use in risk assessment models. This work involved the review of toxicological, epidemiological, and monitoring data to determine if sufficient health effects and exposure data were available to perform a quantitative risk assessment. Dr. McCarthy has also completed a risk assessment for a hazardous waste site. This included a review of the health effects of over a dozen compounds related to coal gasification processes, exposure estimation through inhalation and ingestion, and associated risks posed by the site to the surrounding population. While at ERT her responsibilities included supervision of the analytical laboratory with client interaction for specialized analyses and project reports. At EPA, Dr. McCarthy worked as analytical chemist and supervised major field studies in the Virgin Islands, Puerto Rico, and New York. Dr. McCarthy is a member of several technical societies and has published several technical articles on indoor air quality.

DECESAR SENIOR CONSULTING SCIENTIST EXPERTISE: Air Quality Source Apportionment, Statistical Methodology Atmospheric Chemistry, SUMMARY OF EXPERIENCE Mr. DeCesar is a Senior Consulting Scientist at TRC and has over seven years experience in the development, application and validation of receptor oriented methods of air quality source apportionment. He was the primary contributor in a project which resulted in the development of statistical tools for designing receptor modeling studies to apportion the sources of urban air pollution to a specified level of precision. Mr. DeCesar has managed several urban aerosol source apportionment research projects including: the "Medford Aerosol Characterization Study" (MACS) and an "Evaluation of Chemical Receptor Mode1s for Air Particulate Source Impact Assessment using the PACS Data Set". His responsibilities included report preparation, multivariate statistical analysis, data base management, software development, and chemical analysis of aerosol samples. Mr. DeCesar has been a major contributor in aerosol characterization studies carried out in numerous airsheds including: Kellog and Lewiston, Idaho; Missoula and East Helena, Montana; Portland, Oregon; South Bend, Indiana; and Labrador City, Newfoundland. He successfully quantified the impacts of sources and source types for the airsheds by using data collected in the studies and applying receptor model methodology. Through these studies he gained extensive experience in multivariate statistical analysis, study design, and the management and interpretation of large data sets. Mr. DeCesar is the primary developer of the "Quantitative Source Apportionment System III" (QSAS III) software package. The QSAS III package, distributed by NEA, Inc. of Beaverton, Oregon, is an interactive command-driven system for data management and CMB source apportionment calculations as well as tabular and graphical representation of air quality data in report-ready formats.

REYNOLDS EDUCATION 1979, M.S. 1974, B.A. Oregon State University, Atmospheric Science University of Nebraska, Chemistry SUMMARY OF EXPERIENCE - Mr. Reynolds is a Principal Scientist working in the areas of modeling, permitting and atmospheric studies in the Denver office of TRC. He is currently responsible for all technical inputs and analysis in the projects he is involved with. Mr. Reynolds has conducted and reviewed numerous dispersion and receptor modeling studies for a large variety of sources as well as basic atmospheric research. Some of these studies include such complex sources types as nonferrous smelters, rock quarries, surface mines, petroleum refineries, industrial/utility boilers, lime plants, chemical plants and urbanized regional source interactions. These studies routinely included the development of innovative emission inventory and modeling techniques on a case by case basis. He also has extensive experience in applied meteorology and air pollution field work, using a large array of standard and exotic meteorological and contaminant measuring equipment and tracers, Aside from these major work areas, Mr. Reynolds has extensive experience in computer usage and programming. This includes the application of numerous data and statistical manipulation techniques and dispersion model modification and development. Besides the frequent application of most of EPA's UNAMAP models, he has also applied receptor models and photochemical models to various problems. Prior to joining TRC, Mr. Reynolds worked for the State of Missouri as their meteorologist. There he performed, approved, archived and verified all dispersion modeling, monitoring and meteorology for permits, episodes and air quality planning. He was involved in all regulation and State Implementation Plan technical developments, documentation and expert testimony. Before this he worked for the Air Resource Center at Oregon State University where he was involved with experimental and theoretical solutions to air contaminant deposition and resuspension problems.
