Recommendation 2. A quality control/quality assurance program should be defined, reviewed, approved, and implemented. This program should include internal quality control oversight, an external audit, and targets for data-loss rate. The DOE-FE should consider using consultants to provide advice, technical expertise, and oversight. DOE should also develop a detailed description of procedures for collecting, transporting, and analyzing all samples.
Recommendation 3. The external advisory group for the Upper Ohio River Valley Project should be more actively involved in program development. Regular discussions and workshops should be held to address elements of the project and encourage scientists to make use of the data.
Recommendation 4. Current emissions inventories, source profiles, and data on emissions chemistry should be reviewed for their applicability to the project. DOE should make a commitment to obtaining source profile data for key sources that have the potential to influence the air quality in the Pittsburgh area, including selected coal-fired power plants, transportation sources, and large coking or manufacturing facilities.
Recommendation 5. To improve the data on ambient mass concentrations, particle size distributions (including ultrafine particles [less than 0.1 μm aerodynamic diameter]) should be measured, perhaps using portable units that can be moved from site to site.
Recommendation 6. The program should encourage other investigators or institutions to undertake studies to determine the value of using monitoring data of ambient air quality as a surrogate for personal exposure in epidemiological studies. The program should also encourage others to initiate concommitant health studies that might benefit from data collected by the program.
Recommendation 7. The DOE-FE should reevaluate the project design features, such as the frequency of sampling, based on the experience from the Aerosol Research Inhalation Epidemiology Study (ARIES) in Atlanta to ensure that the data collected meet the needs of contemporaneous or future epidemiological and exposure studies.
