NR 407.025(2)(a)(a) The department shall, if an owner or operator of a stationary source requests it, issue an operation permit that contains terms and conditions, including all terms required under s. NR 407.09 (1), (2) and (4), allowing for the trading of emissions increases and decreases at the stationary source solely for the purpose of complying with a federally-enforceable emissions cap that is established in the operation permit independent of otherwise applicable requirements. The permit applicant shall include in the application proposed replicable procedures and permit terms that ensure the emissions trades are quantifiable and enforceable. The department may not include in the emissions trading provisions any emissions units for which emissions are not quantifiable or for which there are no replicable procedures to enforce the emissions trades. Any operation permit issued pursuant to this subsection shall require compliance with all applicable requirements. NR 407.025(2)(b)(b) For any trade allowed in an operation permit pursuant to par. (a), the owner or operator of the stationary source shall provide the department and, for part 70 sources, the administrator, with written notification a minimum of 7 days in advance of the date on which the proposed trade is to occur. The written notification shall state when the change is proposed to occur and shall describe the changes in emissions that will result and how these changes in emissions will comply with the terms and conditions of the permit. NR 407.025(2)(c)(c) The permit shield described in s. 285.62 (10) (b), Stats., may extend to terms and conditions that allow the increases and decreases in emissions allowed under this subsection.
