         APPEAL FROM THE UNITED STATES DISTRICT COURT

               FOR THE DISTRICT OF PUERTO RICO

      [Hon. Carmen Consuelo Cerezo, U.S. District Judge]


                            Before

                    Torruella, Chief Judge,
               Stahl and Lynch, Circuit Judges.




     Alfredo Ugarte-Castro on brief pro se.
     Guillermo Gil, United States Attorney, Jorge E. Vega-
Pacheco, Assistant United States Attorney, and Nelson Perez
Sosa, Assistant United States Attorney, on brief for appellee.




                      September 29, 2000
            Per Curiam.     Appellant Ugarte-Castro appeals a

denial of his motion for a second resentencing under 18

U.S.C. § 3582(c)(2).      Appellant now seeks a reduction in his

term of imprisonment under the "safety valve" provision.

See 18 U.S.C. § 3553(f).         He says that in 1996, when a

lowering of his guidelines' sentencing range eventuated in

his being resentenced to a 188-month term of imprisonment,

his attorneys "should have also moved for a reduction in his

sentence under the safety valve provision."        The district

court denied the current motion on the merits of the safety

valve factors.

            The district court correctly denied the motion,

although it need not have reached the merits.          The court

lacked authority under § 3582(c)(2) to modify the previously

imposed sentence.    Appellant did not appeal from the 1996

resentencing judgment.      His current motion is not based on

a "subsequently" lowered guidelines range, nor on any of the

other   "limited   circumstances"    which   trigger   a   court's

authority, under § 3582(c), to modify a previously imposed

sentence.    United States v. Jordan, 

, 5 (1st Cir.

1998), cert. denied, 

(1999).

            As the government points out, a district court is

vested with the authority to entertain motions to correct a
sentence pursuant to 28 U.S.C. § 2255.           However, we do not

construe this motion as one brought under § 2255, since it

appears   to   have   been   filed    well   beyond   the     statute's

limitations    period,   appellant     insists   that    it    was   not

intended as a § 2255 petition, and neither the court nor the

parties addressed the complexities of § 2255 below.

           For these reasons, we also need not reach the

parties' arguments about the temporal applicability of the

safety    valve   provision     to     appellant's      sentence      or

resentence.

           Affirmed.
