Abstract |
A summary report is presented of the emission inventory for the Mid-Connecticut Lower Pioneer Valley. The survey provides estimates of the present levels of air pollutant emissions and status of their control. The pollutants which include sulfur oxides, particulates, carbon monoxide, hydrocarbons, and nitrogen oxides are delineated with respect to source type, season of the year, and geographical distribution within the area. The Study Area, which was chosen on the basis of the distribution of population and air pollution sources, consists of 103 cities and towns in portions of Connecticut and Massachusetts. A grid coordinate system was used to show the geographical distribution of emissions within the area. All sources of emissions were classified into four categories: transportation, stationary fuel combustion, solid-waste disposal, and industrial processes. Emissions were estimated by using various indicators such as fuel consumption, refuse burining rates, vehicle-miles, production data, and control efficiencies and emission factors relating these indicators to emission rates.
