For a variance from an effluent limitation that is based on the best control technology available for conventional pollutants under 33 USC 1311(b)(2)(E) and 33 USC 1314(b)(4), or for variances from an effluent limitation that is based on the best available treatment technology economically achievable under 33 USC 1311(b)(2) and 33 USC 1314(b)(2), the request shall be submitted as part of the permit application for reissuance or modification.

(b) Other technology based limitation variance deadlines. Requests for a variance to an effluent guideline limitation under 33 USC 1311(c) or (g) shall comply with the deadlines and requirements in 40 CFR 122.21(m).
