TL;DR: A recently completed study has shown that emissions of participate, carbon monoxide, and organics (including polycyclic organic matter) are relatively high from residential woodburning stoves and fireplaces when compared to emissions from residential gas-and oil-fired furnaces as mentioned in this paper.
Abstract: A recently completed study has shown that emissions of participate, carbon monoxide, and organics (including polycyclic organic matter) are relatively high from residential woodburning stoves and fireplaces when compared to emissions from residential gas- and oil-fired furnaces. Since these emissions include a number of potentially hazardous compounds; the trend toward greater residential wood usage can have a negative impact on local ambient air quality. EPA is currently studying ways to operate existing stoves and design new stoves to minimize air pollutant emissions.

TL;DR: The information presented in this paper is directed to those individuals interested in future air quality control programs aimed at areas that are attaining one or more air quality ambient standards, as defined in Section 116 of the Clean Air Act, as amended.
Abstract: The information presented in this paper is directed to those individuals interested in future air quality control programs aimed at areas that are attaining one or more air quality ambient standards. Section 116 of the Clean Air Act, as amended, requires the Environmental Protection Agency to promulgate regulations for the prevention of significant deterioration (PSD) of air quality in order to protect the nation's clean air resources from hydrocarbons, carbon monoxide, ozone, nitrogen oxides, and lead (Set II pollutants). This program will affect industry siting in many areas of the country, particularly in the rural, undeveloped areas. Among the many alternatives currently being considered by EPA to meet the PSD Set II goals are emission management systems, marketable emission permits, air quality increments, emission fees, and control of transportation related sources. The final regulation may be a combination of several options or may present several alternatives from which a State would choose its sp...

TL;DR: In this article, the authors developed a Sub-regional Energy and Emissions Model (SEEM) to disaggregate the regional industrial figures to the county level according to fuel type and industrial category at the two-digit SIC level.
Abstract: Evaluating the air pollution impacts of energy use in the industrial sector is difficult because of the diversity and multiplicity of sources and a general lack of systematic, up-to-date data collection mechanisms. Fuel-specific energy consumption for a multi-state region is provided by the U.S. Department of Energy PIES model for a base year (1975), together with scenarios for future years. A computer model developed in this study—the Sub-regional Energy and Emissions Model (SEEM)—is applied to disaggregate the regional industrial figures to the county level according to fuel type and industrial category at the two-digit SIC level. The resulting emissions of total suspended particulates (TSP) and sulfur dioxide (SO2) for all industrial categories are estimated at the county level by Incorporating county-specific air pollution regulations in SEEM, and are then aggregated to larger geographical regions. The model has been applied to evaluate the increased air pollution impacts of industrial energy use in t...

TL;DR: In this paper, numerical modeling techniques and regression analysis can be used to extract information from large sets of air quality data, and the use of differential, as opposed to absolute, pollutant concentration values will reduce artifact correlations caused by seasonal, weekly, or daily meteorological fluctuations and will permit more accurate estimation of the regression coefficients.
Abstract: New York City data indicate that seasonal and annual variations in dispersion-normalized air pollutant concentrations appear to accurately reflect changes in source emission patterns. The normalized concentrations make it possible to observe the impact of regulatory changes on ambient air quality without these impacts being obscured by meteorological fluctuations. It is found that numerical modeling techniques and regression analysis can be powerful tools for extracting information from large sets of air quality data. The use of differential, as opposed to absolute, pollutant concentration values will reduce artifact correlations caused by seasonal, weekly, or daily meteorological fluctuations and will permit more accurate estimation of the regression coefficients. This technique was successfully applied to a set of daily pollution measurements whose absolute concentrations were found not to yield a statistically significant fit by multiple regression.
