Current through Register Vol. 48, No. 38, September 20, 2024
a) Except as provided in subsection (f) of this Section, no owner or operator of a source subject to the requirements of this Subpart shall use a subject resin or gel coat at the source unless the resin and gel coat comply with subsection (b)(1) or (b)(2), (c), or (d) of this Section, as well as with subsections (e), (g), and (h) of this Section. For sources complying pursuant to subsection (b) or (c) of this Section, if the non-monomer VOM content of a resin or gel coat exceeds 5 percent, by weight, the excess non-monomer VOM shall be added to the monomer VOM content of the resin or gel coat. The excess non-monomer VOM shall be calculated in accordance with the following equation:

c) Emissions Averaging Alternative. The owner or operator of a source subject to the requirements of this Subpart may elect to include some or all of the subject resin and gel coat operations at the source in the emissions averaging alternative. Resin and gel coat operations utilizing the emissions averaging alternative shall comply with a source-specific monomer VOM mass emission limit on a 12-month rolling average basis, calculated at the end of each calendar month. All subject resin and gel coat operations that do not utilize the emissions averaging alternative shall comply with the requirements in subsection (b) or (d) of this Section, as well as with all other applicable requirements in this Section.
Equation 2:
Monomer VOM Limit |
= |
where:
Monomer VOM Limit |

Total allowable monomer VOM that can be emitted from the open molding operations included in the average, expressed in kilograms per 12-month period; |
MR |

Mass of clear gel coat used in the past 12 months, excluding any materials that are exempt, expressed in Mg; |
MTR |

Mass of tooling resin used in the past 12 months, excluding any materials that are exempt, expressed in Mg; |
MTG |

Mass of tooling gel coat used in the past 12 months, excluding any materials that are exempt, expressed in Mg. |
The numerical coefficients associated with each term on the right hand side of Equation 2 are the allowable monomer VOM emission rates for that particular material in units of kg VOM/Mg of material used.
Equation 3:
where:
Monomer VOM Emissions |
= |
Monomer VOM emissions calculated using the monomer VOM emission equations for each operation included in the average, expressed in kg; |
PVR |
= |
Weighted-average monomer VOM emission rate for production resin used in the past 12 months, expressed in kg/Mg, calculated in accordance with Equation 4 in subsection (c)(3); |
MR |

For all filled production and tooling resins, the owner or operator of a source subject to this Subpart shall adjust the monomer VOM emission rates determined pursuant to subsections (b) and (c) of this Section using Equation 5 in subsection (e)(3). If complying pursuant to subsection (b), the emission rate determined using Equation 5 shall not exceed the limitations set forth in subsections (e)(1) and (e)(2) of this Section. If complying pursuant to subsection (c), the value of PVF, calculated using Equation 5, shall be used as the value of PVi in Equation 4, as set forth in subsection (c)(3) of this Section.
