Section 218.940  Applicability

a)         Maximum theoretical emissions:

1)         A source is subject to this Subpart if it contains process emission units not regulated by Subparts B, E, F (excluding Section 218.204(l)), H (excluding Section 218.405), Q, R, S, T (excluding Section 218.486), V, X, Y, Z or BB of this Part, which as a group both:

A)        Have maximum theoretical emissions of 90.7 Mg (100 tons) or more per calendar year of VOM, and

B)        Are not limited to less than 90.7 Mg (100 tons) of VOM emissions per calendar year in the absence of air pollution control equipment through production or capacity limitations contained in a federally enforceable permit or a SIP or FIP revision.

2)         If a source is subject to this Subpart as provided above, the requirements of this Subpart shall apply to a source's miscellaneous formulation manufacturing process emission units which are not included within any of the categories specified in Subparts B, E, F, H, Q, R, S, T, V, X, Y, Z, AA, or BB of this Part.

b)         Potential to emit:

1)         A source is subject to this Subpart if it has the potential to emit 22.7 Mg (25 tons) or more of VOM per year, in aggregate, from emission units that are:

A)        Not regulated by Subparts B, E, F, H, Q, R, S, T (excluding Section 218.486), V, X, Y, Z, or BB of this Part, or

B)        Not included in any of the following categories:  synthetic organic chemical manufacturing industry (SOCMI) distillation, SOCMI reactors, wood furniture, plastic parts coating (business machines), plastic parts coating (other), offset lithography, industrial wastewater, autobody refinishing, SOCMI batch processing, volatile organic liquid storage tanks and clean-up solvents operations.

2)         If a source is subject to this Subpart as provided above, the requirements of this Subpart shall apply to a source's miscellaneous formulation manufacturing process emission units which are:

A)        Not included within any of the categories specified in Subparts B, E, F, H, Q, R, T, V, X, Y, Z, AA, BB, CC, or DD of this Part, or

B)        Not included in any of the following categories:  synthetic organic chemical manufacturing industry (SOCMI) distillation, SOCMI reactors, wood furniture, plastic parts coating (business machines), plastic parts coating (other), offset lithography, industrial wastewater, autobody refinishing, SOCMI batch processing, volatile organic liquid storage tanks and clean-up solvents operations.

c)         If a source ceases to fulfill the criteria of subsections (a) and/or (b) above, the requirements of this Subpart shall continue to apply to a miscellaneous formulation manufacturing process emission unit which was subject to the control requirements of Section 218.946 of this Part.

d)         No limits under this Subpart shall apply to emission units with emissions of VOM to the atmosphere less than or equal to 2.3 Mg (2.5 tons) per calendar year if the total emissions from such emission units not complying with this Section does not exceed 4.5 Mg (5.0 tons) per calendar year.

e)         For the purposes of this Subpart, an emission unit shall be considered regulated by a Subpart if it is subject to the limits of that Subpart.  An emission unit is considered not regulated by a Subpart if it is not subject to the limits of that Subpart, e.g., the emission unit is covered by an exemption in the Subpart or the applicability criteria of the Subpart are not met.

f)         For the purposes of this Subpart, VOM emissions in the absence of air pollution control equipment are the emissions of VOM which would result if no air pollution control equipment were used.

g)         The control requirements in Subpart QQ shall not apply to sewage treatment plants; vegetable oil extraction and processing; coke ovens (including by-product recovery plants); fuel combustion units; bakeries; barge loading facilities; jet engine test cells; production of polystyrene foam insulation board including storage and extrusion of scrap where blowing agent is added to the polystyrene resin at the source, but not including blending and preliminary expansion of resin prior to molding where blowing agent is incorporated into the polystyrene resin by the producer of the resin; production of polystyrene foam packaging not including blending and preliminary expansion of resin prior to molding where blowing agent is incorporated into the polystyrene resin by the producer of the resin and not including storage and extrusion of scrap where blowing agent is added to the polystyrene resin at the source; and iron and steel production.

h)         The control requirements of this Subpart shall not apply to the solvation mixers at the container sealant manufacturing facility located at 6050 West 51st Street in Chicago, Illinois.
