The cost of air pollution control to cotton ginners
1974
Wilmot, Charles A. (Charles Archibald) | Looney, Zolon Marion | McCaskill, Oliver L.
"Under present and anticipated control regulations, cotton gins will need to reduce air pollution. Estimates for the cost of installing cyclones (which remove particles from the air by centrifugal force) and inline air filters, plus the costs of overhead storage hoppers and trucks for hauling, range from nearly $24,000 for a 6-bale per hour gin designed for machine-picked cotton to well over $53,000 for a plant capable of ginning 36 bales of stripper-harvested cotton per hour. If future air pollution regulations require all of the approximately 3,900 active gins to install this equipment, total investment cost would exceed $100 million."--Page iv.
