Current through Register Vol. 48, No. 38, September 20, 2024
a) Testing Methods.
Separately weigh the polyester resin material and the reinforcement materials before they are introduced into the mold. Weigh the molded product after it has cooled so that it can be manually handled but no sooner than one hour after removal of the product from the mold. The percent weight loss shall be determined according to the following equation:
Where,
PWL |
= |
Percent Weight Loss; |
A |
= |
Weight of polyester resin materials; |
B |
= |
Weight of reinforcement material; |
C |
= |
Weight of cooled molded product after at one hour elapsed time. |
b) When in the opinion of the Agency it is necessary to conduct sampling and analysis to demonstrate compliance with Section 218.668 of this Part, the owner or operator of a polyester resin products manufacturing process subject to the requirements of this Subpart shall, at his own expense, conduct such sampling and analysis in accordance with the applicable test methods and procedures specified in subsection (a) above. The Agency's decision to invoke this subsection may be based on such factors including, but not limited to, a change in operation of the polyester resin products manufacturing process, or a reasonable belief that a previous test resulted in erroneous data.
c) Nothing in this Section shall limit the authority of USEPA pursuant to the Clean Air Act, as amended, to require sampling and analysis.
