New Government Report: Air Quality
by David C. Trimble
Paperback, 34 pages, 2011, $20.00
Tall smokestacks (TS) — stacks of 500 feet or higher, which are primarily used at coal power plants — release air pollutants high into the atmosphere to help limit the impact of these emissions on local air quality. The 1977 amend. to the Clean Air Act encourage the use of pollution control equipment over dispersion techniques, such as TS, to meet national air standards. This report discusses: (1) the number and location of TS of 500 feet or higher at coal power plants; (2) what is known about such stacks’ contribution to the interstate transport of air pollution and the pollution controls installed at plants with these stacks; and (3) the number of TS that were built above good engineering practice height since 1988 and the reasons for this.
