A study was made to assess the potential air quality impacts of a 2600 MW(t) regional district heating/cogeneration system in Minneapolis-St. Paul. Estimates were made of the SO/sub 2/ and particulate emission rates and local concentrations with and without the district heating/cogeneration system. A methodology employing fuel use data was developed to estimate emission rates from sources not included in National Emission Data System NEDS. The predictions were made on an annual average basis and on 24 h average basis for five winter days and one late summer day. With the development of the district heating/cogeneration system, the total SO/sub 2/ emission rate could decrease (up to 3%) or increase (up to 11%) depending on the changes in the retrofitted power plant load factors. In all cases there would be decreases (up to 30%) in the SO/sub 2/ concentrations due to the central facilities replacing many small heating units. The particulate total emission rates and concentrations both were predicted to decrease slightly.
