Alfranzo T. Davis appeals the decision of the Merit Systems Protection Board, dismissing his petition as untimely filed. Davis v. U.S. Postal Serv., 104 M.S.P.R. 265 (M.S.P.B. 2006). We affirm.

Davis was required to file his board appeal within 30 days of receiving notice of the Postal Service’s decision to remove him, or to show good cause why he was unable to timely file. 5 C.F.R. §§ 1201.12, 1201.22. Davis, however, filed more than 30 days after receiving the agency’s decision letter, and he failed to present the board with evidence of good cause. He did not argue before it that the medical records he now submits established good cause; and to the extent he so argues to this court, we do not infer good cause from them. Finally, Davis’ request that the board consider the date his grievance was resolved in determining when his 30 days began to run is without merit. His grievance was a separate proceeding, and does not affect the deadlines under 5 C.F.R. § 1201.22.
