Md. Code Regs. 26.11.06.05 - Sulfur Compounds from Other than Fuel-Burning Equipment
A. General
Conditions. All calculations of emissions governed by this regulation shall be
adjusted to standard conditions and 7 percent oxygen. "PPM" means parts per
million by volume.
B. Areas I, II,
V and VI.
(1) A person may not cause or
permit the discharge into the atmosphere from installations other than
fuel-burning equipment of gases containing more than 500 ppm of sulfur dioxide.
Installations constructed before January 17, 1972, are limited to not more than
2,000 ppm sulfur dioxide.
(2) A
person may not cause or permit the discharge into the atmosphere from
installations other than fuel-burning equipment of gases containing sulfuric
acid, sulfur trioxide, or any combination of them greater than 35 milligrams
per cubic meter reported as sulfuric acid. Any installation constructed before
January 17, 1972, is limited to not more than 70 milligrams per cubic meter of
sulfuric acid, sulfur trioxide, or any combination of them, reported as
sulfuric acid.
C. Areas
III and IV.
(1) A person may not cause or
permit the discharge into the atmosphere from installations other than
fuel-burning equipment of gases containing more than 500 ppm of sulfur dioxide.
Installations constructed before February 21, 1971, are limited to not more
than 2,000 ppm sulfur dioxide.
(2)
A person may not cause or permit the discharge into the atmosphere from
installations other than fuel-burning equipment of gases containing sulfuric
acid, sulfur trioxide, or any combination of them, greater than 35 milligrams
per cubic meter reported as sulfuric acid. Any installation constructed before
February 21, 1971, is limited to not more than 70 milligrams per cubic meter of
sulfuric acid, sulfur trioxide, or any combination of them, reported as
sulfuric acid.
D.
Exceptions. The Secretary may authorize the operation of a scavenger or
recovery plant to reclaim sulfur compounds which would otherwise be emitted
into the air, provided the operation of the scavenger or recovery plant would
reduce total emissions of sulfur compounds at least 95 percent with the plant
in operation, compared to emissions when the plant is not operating. This
authorization may result in emissions of sulfur compounds whose concentrations
exceed those permitted by §§B and C of this regulation. This section does not
apply to sulfuric acid manufacturing operations.
