872.22—How does OSM distribute and award historic coal funds?

For the Federal fiscal years beginning . . . The amount of historic coal funds we annually distribute to you will be . . .
(1) October 1, 2007 and October 1, 2008 50 percent of the amount we calculate using the formula described in paragraph (b) of this section.
(2) October 1, 2009 and October 1, 2010 75 percent of the amount we calculated using the formula described in paragraph (b) of this section.
(3) October 1, 2011 and continuing through September 30, 2022 100 percent of the amount we calculate using the formula described in paragraph (b) of this section.
(4) October 1, 2022 (fiscal year 2023), and thereafter 100 percent of the amount we calculate using the formula described in paragraph (b) of this section until funds are no longer available or you have reclaimed your remaining Priority 1 and 2 coal problems.
(d) In any given year, we will only distribute to you the historic coal funds that you need to reclaim your unfunded Priority 1 or 2 coal problems. Your distribution of State or Tribal share funds under § 872.14 or § 872.17 plus your distribution of historic coal funds along with unused funds from prior allocations could be more than you need to reclaim your remaining high priority problems. If that occurs, we will reduce the historic coal funds we distribute to you to the amount that you need to fully fund reclamation of all your remaining Priority 1 or 2 coal problems.
