Convicted in 1997 on drug charges and given a 144-month sentence, Douglas Green (federal prisoner # 72853-079), pursuant to 28 U.S.C. § 2241, challenges, pro se, the Bureau of Prisons’ (BOP’s) method of calculating his good-time credits under 18 U.S.C. § 3624(b).

Green claims the BOP incorrectly interpreted § 3624(b), resulting in the potential loss of 84 days of good-time credits. Green seeks to have the BOP ordered to credit him the total amount of good-time credits (648 days) to which he believes he is entitled, based on his 12-year sentence.

In Sample v. Morrison, 406 F.3d 310, 312-13 (5th Cir. 2005), for the claim Green advances, the appeal was dismissed for lack of subject-matter jurisdiction because the petition was not ripe for review. The court concluded the “temporally distant and speculative nature” of the claims rendered the § 2241 petition premature. Id.

Green is seeking the same relief found premature in Sample. Therefore, this instant appeal is DISMISSED for lack of subject-matter jurisdiction.

APPEAL DISMISSED.
