| Existing and new sources | Source type | Sterilization chamber vent | Aeration room vent | Chamber exhaust vent |
|---|---|---|---|---|
| Source size | <907 kg (<1 ton) | No control required; minimal recordkeeping requirements apply (see §63.367(c)). | ||
| ≥907 kg and <9,070 kg (≥1 ton and <10 tons) | 99% emission reduction (see §63.362(c)) | No control | No control. | |
| ≥9,070 kg (≥10 tons) | 99% emission reduction (see §63.362(c)) | 1 ppm maximum outlet concentration or 99% emission reduction (see §63.362(d)) | No control. | |
(b) Applicability of emission limits. The emission limitations of paragraphs (c), (d), and (e) of this section apply during sterilization operation. The emission limitations do not apply during periods of malfunction.
(c) Sterilization chamber vent at sources using 1 ton. Each owner or operator of a sterilization source using 1 ton shall reduce ethylene oxide emissions to the atmosphere by at least 99 percent from each sterilization chamber vent.
(d) Aeration room vent at sources using 10 tons. Each owner or operator of a sterilization source using 10 tons shall reduce ethylene oxide emissions to the atmosphere from each aeration room vent to a maximum concentration of 1 ppmv or by at least 99 percent, whichever is less stringent, from each aeration room vent.
