June 9, 2020
You must use one of the compliance alternatives in paragraph (a) or (b) of this section to meet the emission limits in §63.5986.
(a) Monthly average alternative, without using an add-on control device. Use coatings in such a way that the monthly average HAP emissions do not exceed the emission limits in Table 2 to this subpart.
(b) Monthly average alternative, using an add-on control device. Use a control device to reduce HAP emissions so that the monthly average HAP emissions do not exceed the emission limits in Table 2 to this subpart.
