§ 63.2840 What emission requirements must I meet?
For each facility meeting the applicability criteria in § 63.2832, you must comply with either the requirements specified in paragraphs (a) through (d), or the requirements in paragraph (e) of this section. You must also comply with the requirements in paragraph (g) of this section. You must comply with the work practice standard provided in paragraph (h) of this section, if you choose to operate your source under an initial startup period subject to § 63.2850(c)(2) or (d)(2).
(a)
(1) The emission requirements limit the number of gallons of HAP lost per ton of listed oilseeds processed. For each operating month, as defined in § 63.2872, you must calculate a compliance ratio which compares your actual HAP loss to your allowable HAP loss for the previous 12 operating months as shown in Equation 1 of this section. Equation 1 of this section follows:
(2) Equation 1 of this section can also be expressed as a function of total solvent loss as shown in Equation 2 of this section. Equation 2 of this section follows:

Table 1 of § 63.2840—Oilseed Solvent Loss Factors for Determining Allowable HAP Loss
| Type of oilseed process | A source that... | Oilseed solvent loss factor (gal/ton) | |
|---|---|---|---|
| Existing sources | New sources | ||
| (i) Corn Germ, Wet Milling | processes corn germ that has been separated from other corn components using a “wet” process of centrifuging a slurry steeped in a dilute sulfurous acid solution | 0.4 | 0.3 |
| (ii) Corn Germ, Dry Milling | processes corn germ that has been separated from the other corn components using a “dry” process of mechanical chafing and air sifting | 0.7 | 0.7 |
| (iii) Cottonseed, Large | processes 120,000 tons or more of a combination of cottonseed and other listed oilseeds during all normal operating periods in a 12 operating month period | 0.5 | 0.4 |
| (iv) Cottonseed, Small | processes less than 120,000 tons of a combination of cottonseed and other listed oilseeds during all normal operating periods in a 12 operating month period | 0.7 | 0.4 |
| (v) Flax | processes flax | 0.6 | 0.6 |
| (vi) Peanuts | processes peanuts | 1.2 | 0.7 |
| (vii) Rapeseed | processes rapeseed | 0.7 | 0.3 |
| (viii) Safflower | processes safflower | 0.7 | 0.7 |
| (ix) Soybean, Conventional | uses a conventional style desolventizer to produce crude soybean oil products and soybean animal feed products | 0.2 | 0.2 |
| (x) Soybean, Specialty | uses a special style desolventizer to produce soybean meal products for human and animal consumption | 1.7 | 1.5 |
| (xi) Soybean, Combination Plant with Low Specialty Production | processes soybeans in both specialty and conventional desolventizers and the quantity of soybeans processed in specialty desolventizers during normal operating periods is less than 3.3 percent of total soybeans processed during all normal operating periods in a 12 operating month period. The corresponding solvent loss factor is an overall value and applies to the total quantity of soybeans processed. | 0.25 | 0.25 |
| (xii) Sunflower | processes sunflower | 0.4 | 0.3 |
