Rule 291.
(1) This
rule does not apply if prohibited by
R
336.1278 and unless the requirements of
R
336.1278a have been met.
(2) The requirement of
R
336.1201(1) to obtain a
permit to
install does not apply to any emission unit in which potential emissions meet
the conditions listed in subdivisions (a) to (d) of this subrule and table 23
for all air contaminants listed. In addition, records shall be maintained in
accordance with subdivisions (e) and (f) of this subrule.
(a) The combined potential emissions of all
toxic air contaminants with screening levels greater than or equal to 0.04
micrograms per cubic meter and less than 2 micrograms per cubic meter shall not
exceed 0.12 tons per year.
(b) The
combined potential emissions of all toxic air contaminants with screening
levels greater than or equal to 0.005 micrograms per cubic meter and less than
0.04 micrograms per cubic meter shall not exceed 0.06 tons per year.
(c) The combined potential emissions of all
toxic contaminants with screening levels less than 0.005 micrograms per cubic
meter shall not exceed 0.006 tons per year.
(d) The emission unit has no potential
emissions of asbestos and/or subtilisin proteolytic enzymes.
(e) A description of the emission unit shall
be maintained throughout the life of the unit.
(f) Documentation and/or calculations
identifying the quality, nature, and quantity of the
air contaminant emissions
are maintained in sufficient detail to demonstrate that the potential emissions
are less than those listed in subdivisions (a) to (d) of this subrule and Table
23. Such documentation shall include the toxic
air contaminant screening level
applicable at the time of installation and/or
modification of the emission
unit.
