No person shall cause, suffer, allow or permit
visible smoke to be emitted into the outdoor air from the combustion
of fuel in any stationary indirect heat exchanger having a rated hourly
capacity of less than 200,000,000 British thermal units (BTUs) gross
heat input or discharging through a stack or chimney having an internal
cross-sectional dimension of less than 60 inches.
No person shall cause, suffer, allow or permit
smoke the shade or appearance of which is darker than No. 1 on the
Ringelmann Smoke Chart, or greater than twenty-percent opacity, exclusive
of water vapor, to be emitted into the outdoor air from the combustion
of fuel in any stationary indirect heat exchanger having a rated hourly
capacity of 200,000,000 BTUs or greater gross heat input or discharging

vehicle while operating on the public highways.
Any person responsible for the construction,

equipment for determining the density or opacity of smoke being discharged
into the open air and shall conduct such smoke tests using methods
approved by the Director.
