Code of Federal Regulations Title 40. Protection of Environment 40 CFR Pt. 63, Subpt. EEEE, Tbl. 2b Table 2b to Subpart EEEE of Part 63—Emission Limits For Storage Tanks At Certain Existing Affected Sources

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)

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.
