Section 250-RICR-120-05-26.7 - StandardsA. Any source commencing operation after November 19, 1992 must meet the following emission limitations upon commencing operations: 1. Surface condensers or equivalent controls a. If surface condensers are used, the condenser outlet gas temperature shall not exceed the allowable temperature limit described for each associated vapor pressure in the following table; or Allowable condenser outlet gas temperature, EC | VOC vapor pressure at 20EC, kPa (psi) |
-25 | >40.01 | (5.8) |
-15 | >20.0 | (2.9) |
0 | >10.0 | (1.5) |
10 | >7.0 | (1.0) |
25 | >3.5 | (0.5) |
b. If other controls such as carbon absorption or incineration are used, the VOC emissions shall be reduced by at least as much as they would be by using a surface condenser. All such controls must be approved by the Department.2. Air dryers and production equipment exhaust systems a. The owner or operator of a synthesized pharmaceutical manufacturing facility subject to this regulation shall reduce the VOC emissions from all air dryers and production equipment exhaust systems: (1) By at least ninety percent (90%) on an hourly basis if actual emissions from all air dryers and production equipment exhaust are 150 kg/day (330 lb/day) or more of VOC, or(2) To 15.0 kg/day (33 lb/day) or less if actual emissions from all air dryers and production equipment exhaust are less than 150 kg/day (330 lb/day) of VOC.3. Storage Tanks a. The owner or operator of a synthesized pharmaceutical manufacturing facility subject to this regulation shall reduce the VOC emissions from storage tanks by: (1) Providing a vapor balance system or equivalent control that is at least ninety percent (90%) effective in reducing emissions from truck or railcar deliveries to storage tanks with capacities greater than 7,500 liters (L) (2,000 gallons [gal]) that store VOC with vapor pressures greater than 28.0 kilo Pascals (kPa) (4.1 pounds per square inch [psi]) at 20 C (68°F); and(2) Installing pressure/vacuum conservation vents set at a minimum pressure of 0.2 kPa (0.03 pounds per square inch atmospheric [psia]) on all storage tanks that store VOC with vapor pressures greater than 10.0 kPa (1.5 psi) at 20°C (68°F).4. Centrifuges, rotary vacuum filters, and other filters a. The owner or operator of a synthesized pharmaceutical facility subject to this regulation shall enclose all centrifuges, rotary vacuum filters, and other filters having an exposed liquid surface if the liquid contains VOC and exerts a total VOC vapor pressure of 3.50 kPa (0.5 psi) or more at 20°C (68°F), as determined by ASTM D 2879-10, incorporated in § 26.4(B) of this Part.5. In-process tanks a. The owner or operator of a synthesized pharmaceutical facility subject to this regulation shall install covers on all in-process tanks that contain VOC at any time. These covers shall be constructed of a nonporous or nonabsorbent material and form a tight seal with the sides of the tank and have no gaps or holes. These covers shall remain closed at all times except when production, sampling, maintenance, or inspection procedures require operator access.6. Leaks a. The owner or operator of a synthesized pharmaceutical manufacturing facility subject to this regulation shall visually inspect for liquid leaks once per week and use a portable VOC detector to inspect for vapor leaks once per month to inspect all equipment listed in §§ 26.6(A)(1) through (11) of this Part. All leak repairs shall be completed as soon as practicable but no later than fifteen (15) calendar days after the leak is found.250 R.I. Code R. 250-RICR-120-05-26.7
