This subpart requires you to obtain an operating permit under title V of the Clean Air Act and implementing regulations (``title V permit'') unless you are only subject to the recordkeeping and reporting requirements listed at Sec. 62.14400(b)(1) or (b)(2), and Sec. 62.14400(c), of this subpart. Also, if you own or operate a unit described in Sec. 62.14400(b)(3), (b)(4), (b)(5) or (b)(6), you are not subject to any requirements of this subpart; therefore, this subpart does not require you to obtain a title V permit.
