§ 3582. Imposition of a sentence of imprisonment
(a) Factors to be considered in imposing a term of imprisonment.The court, in determining whether to impose a term of imprisonment, and, if a term of imprisonment is to be imposed, in determining the length of the term, shall consider the factors set forth in section 3553(a) to the extent that they are applicable, recognizing that imprisonment is not an appropriate means of promoting correction and rehabilitation. In determining whether to make a recommendation concerning the type of prison facility appropriate for the defendant, the court shall consider any pertinent policy statements issued by the Sentencing Commission pursuant to 28 U.S.C. 994(a)(2).

(i) extraordinary and compelling reasons warrant such a reduction; or
(ii) the defendant is at least 70 years of age, has served at least 30 year in prison, pursuant to a sentence imposed under section 3559(c), for the offense or offenses for which the defendant is
