  R307-250-11. Use of Allowances from a Previous Year  

Latest version.

  • (1) Any allowance that is held in a compliance account or general account will remain in the account until the allowance is either deducted in conjunction with the compliance process, or transferred to another account.

    (2) In order to demonstrate compliance under R307-250-12(1) for a control period, WEB sources shall only use allowances allocated for that control period or any previous year.

    (3) If flow control procedures for the current control period have been triggered as outlined in SIP Section XX.E.3.h(2), then the use of allowances that were allocated for any previous year will be limited in the following ways.

    (a) The number of allowances that are held in each compliance account and general account as of the allowance transfer deadline for the immediately previous year and that were allocated for any previous year will be determined.

    (b) The number determined in (a) above will be multiplied by the flow control ratio established in accordance with SIP Section XX.E.3.h to determine the number of allowances that were allocated for a previous year that can be used without restriction for the current control period.

    (c) Allowances that were allocated for a previous year in excess of the number determined in (b) above may also be used for the current control period. If such allowances are used to make a deduction, two allowances must be deducted for each deduction of one allowance required under R307-250-12.

    (4) Special provisions for the year 2018. After compliance with the 2017 allowance limitation has been determined in accordance with R307-250-12(1), allowances allocated for any year prior to 2018 shall not be used for determining compliance with the 2018 allowance limitation or any future allowance limitation.

    (5) Special Reserve Compliance Accounts. Unused allowances in any special reserve compliance account will be retired after the compliance deductions under R307-250-12 have been completed for each control period, and shall not be available for use in any future control period.
