The Department of Environmental Quality amended La. Admin. Code 33:III.1101, 1106 and 1107, Control of Emissions of Smoke. Changes would change the provision allowing for one six-minute period in 60 consecutive minutes during which smoke opacity may exceed 20% so that it is not limited to activities involving the cleaning of a fire box or building of a new fire, soot blowing or lancing, charging of an incinerator, equipment changes, ash removal, or rapping of precipitators. http://www.doa.la.gov/osr/reg/1104/1104.pdf pp. 1143-44.
