255C. Any equipment that may produce air pollutants as set forth
in this subtitle shall be operated and maintained in such a manner
that a nuisance is not created. This shall include the continuous emis-

255D. Except as noted below, a permit shall be obtained from the
Building Engineer for the construction, installation, remodeling, or
major alteration of any equipment, device, or process that may pro-
duce in its operation one or more of the air pollutants set forth in
this subtitle.

Plans and specifications for such equipment, device, or process shall
be submitted, as required by the Building Engineer. If building plans
include this information in sufficient detail for appraisal, no separate
plans need be filed. Upon a finding that the proposed equipment,
device or process is satisfactory for purposes of preventing air pollu-
tion as defined in this subtitle, the Building Engineer shall issue a
permit. If the submission is part of a set of building plans, no sep-
arate permit need be issued, but a note must be added to the building
permit application indicating suitability for air pollution control. The
Building Engineer may request the assistance of the Health Officer
in determining such suitability.

Exceptions to this section are as follows:

(1)  Gas-fired equipment when UL listed commercial equipment is

waive the requirement to use only approved equipment for these
installations.
