(a) Visibility through the exhaust effluent of an incinerator, including an air curtain incinerator, may not
be reduced by visible emissions, excluding condensed water vapor, by more than 20 percent averaged
over any six consecutive minutes
18 AAC 50.070- see item 4.1.a
Job Aid Item: 4.1.c
Text: Emissions IAW 18 AAC 50.110. No emissions which would immediately threaten health,
property, or animal life.
Background: This is a broader nuisance regulation compared with the marine vessel emissions
regulation. It is also able to capture items like burning toxic wastes, soot blows that create sheens or
hazardous conditions, and thick smoke that creates a hazard to others. This regulation is not limited to
stack emissions, but covers open burning of wastes and other potential air pollution sources.
What to check: Check for large volumes of black or white smoke from the stacks. Check for soot raining
down from exhaust onto the ship or docks or into the water. Check for sheens caused by soot.
