- Table 2b to Subpart EEEE of Part 63—Emission Limits For Storage Tanks At Certain Existing Affected Sources
As stated in § 63.2346(a)(5), beginning no later than the compliance dates specified in § 63.2342(e), the requirements in this Table 2b to this subpart apply to storage tanks at an existing affected source in lieu of the requirements in Table 2 to this subpart, item 1 for storage tanks at an existing affected source.
| If you own or operate . . . | And if . . . | Then you must . . . | 1. A storage tank at an existing affected source with a capacity ≥18.9 cubic meters (5,000 gallons) and <75.7 cubic meters (20,000 gallons) | a. The stored organic liquid is not crude oil or condensate and if the annual average true vapor pressure of the total Table 1 organic HAP in the stored organic liquid is ≥27.6 kilopascals (4.0 psia) | i. Reduce emissions of total organic HAP (or, upon approval, TOC) by at least 95 weight-percent or, as an option, to an exhaust concentration less than or equal to 20 ppmv, on a dry basis corrected to 3- percent oxygen for combustion devices using supplemental combustion air, by venting emissions through a closed vent system to a flare meeting the requirements of §§ 63.983 and 63.2380, or by venting emissions through a closed vent system to any combination of nonflare control devices meeting the applicable requirements of subpart SS of this part and § 63.2346(l); OR. | ii. Comply with the work practice standards specified in Table 4 to this subpart, items 1.a, 1.b, or 1.c for tanks storing liquids described in that table. | b. The stored organic liquid is crude oil or condensate | i. See the requirement in item 1.a.i or ii of this table. | 2. A storage tank at an existing affected source with a capacity ≥75.7 cubic meters (20,000 gallons) and <151.4 cubic meters (40,000 gallons) | a. The stored organic liquid is not crude oil or condensate and if the annual average true vapor pressure of the total Table 1 organic HAP in the stored organic liquid is ≥13.1 kilopascals (1.9 psia) | i. See the requirement in item 1.a.i or ii of this table. | b. The stored organic liquid is crude oil or condensate | i. See the requirement in item 1.a.i or ii of this table. | 3. A storage tank at an existing affected source with a capacity ≥151.4 cubic meters (40,000 gallons) and <189.3 cubic meters (50,000 gallons) | a. The stored organic liquid is not crude oil or condensate and if the annual average true vapor pressure of the total Table 1 organic HAP in the stored organic liquid is ≥5.2 kilopascals (0.75 psia) | i. See the requirement in item 1.a.i or ii of this table. | b. The stored organic liquid is crude oil or condensate | i. See the requirement in item 1.a.i or ii of this table. |
