eCFR Subpart RRR  [ecfr.gov]
This subpart applies to:
- Affected facilities that are part of a process unit that produces any of the chamicals listed in 40 CFR 60.707 as a product, co-product, by-product, or intermediate, and that commence construction, modification, or reconstruction after June 29, 1990.
Affected facilities:
- Reactor processes that do not discharge their vent stream into a recovery system;
- The combination of a reactor process and the recovery system into which it discharges its vent stream;
- Combinations of two or more reactor processes and the common recovery system into which their vent streams are discharged.
Not subject to this subpart:
- Any reactor process designed and operated as a batch operation;
- Any reactor process operating as part of a process unit that produces beverage alcohols;
- Any reactor process that does not use, contain, or produce any VOC;
- Any reactor process that is subject to NSPS DDD;
Partial Exemptions*:
- Affected facilities with a total resource effectiveness (TRE) index value greater than 8.0;
- Affected facilities in a process unit with a total design capacity for all chemicals produced within that unit of less than 1 gigagram per year (1,100 tons per year);
- Affected facilities operated with a vent stream flow rate less than 0.011 scm/min;
- Affected facilities with vent streams that are routed to a distillation unit subject to NSPS NNN, with no other releases to the air except for a pressure relief valve;
- Affected facilities operating with a concentration of total organic compounds (less methane and ethane) in the vent stream of less than 300 ppmv as measured by Method 18; or concentrations of TOC in the vent stream of less than 150 ppmv as measured by Method 25A.
*These facilities must still comply with certain testing, recordkeeping, and reporting requirements. Please see the rule text for full details. |
