FOUR ADDITIONAL SOURCE CATEGORIES
SUBJECT TO THE GENERIC MACT
Ethylene production, carbon black production, cyanide production and spandex production facilities will now have to comply with the provisions of the generic MACT standards codified in 40 CFR Part 63, Subpart YY. This addition was published by the EPA in a final rule on July 12, 2002 (67 FR 46258 – 46289). The standards initially applied to acetal resin production, acrylic and modacrylic fiber production, hydrogen fluoride production and polycarbonate production facilities.
The generic MACT standards include the following regulations in 40 CFR Part 63:
 |
Subpart SS – General MACT standards for closed vent systems, HAP control and recovery devices, and fuel gas systems and other processes to which HAP emissions are routed; |
|
Subpart TT – General MACT Level 1 controls for fugitive HAP emissions from equipment; |
|
Subpart UU – General MACT Level 2 controls for fugitive HAP emissions from equipment |
|
Subpart WW – General MACT Level 2 controls for HAP-containing storage vessels; and |
|
Subpart YY – Generic MACT standards. |
The new final rule adds Subpart XX which specifies control requirements for waste streams from ethylene production units. The new rule also revises each subpart to specify which authorities EPA will retain, clarifies the conditions in which certain test methods can be used to measure the percent HAP reduction across a control device, and clarifies bypass line monitoring requirements.
The additional source categories which are existing must comply with the rule within three (3) years of rule promulgation, or by July 12, 2005. New sources that begin construction or reconstruction after December 6, 2000, but before the effective date would be given to July 12, 2005 to comply if the applicable final MACT standard provisions are more stringent than the proposed rule and the source complies with the proposed version of the applicable provisions during the three (3) year interim period. Sources beginning construction or reconstruction after the effective date must comply upon start-up.
