D.C. Mun. Regs. tit. 30, § 914
914.1 The prize pool for all prize categories shall consist of up to forty-nine percent (0.49%) and ninety-six one-hundredths percent (0.96%) of each drawing period's sales, including tax, after the POWERBALL® prize reserve accounts reach the amounts designated by the Executive Director in accordance with all agreements governing the conduct of POWERBALL® and Power Play. Once the prize reserve accounts exceed the designated amounts, the excess shall become part of the prize pool. Any amount remaining in the prize pool at the end of this game shall be carried forward to a replacement game prize reserve account or expended as otherwise directed by the Executive Director in accordance with all agreements governing the conduct of POWERBALL® and Power Play.
914.2 An additional four-one hundredths of one percent (0.04%) of sales, including tax, may be collected and placed in trust in one (1) or more prize reserve accounts until the prize reserve accounts reach the amounts designated by the Executive Director in accordance with all agreements governing the conduct of POWERBALL® and Power Play.
914.3 In certain rare instances, the POWERBALL® set prize amount may be less than the amount shown. In such case, the Power Play prizes will be changed to an amount announced at the draw. For example, if the Match 4+1 POWERBALL® set prize amount of ten thousand dollars ($10,000) becomes five thousand dollars ($5,000) under the rules of the POWERBALL® game, then a Power Play player winning that prize amount would win twenty thousand dollars ($20,000).
914.4 Power Play does not apply to the POWERBALL® Grand Prize or to any Bonus Prize.
914.5 REPEALED
