2005 Federal Sentencing Guidelines
Chapter 2 - PART
J - OFFENSES INVOLVING THE ADMINISTRATION OF JUSTICE
§2J1.7. Commission of Offense While on Release
If an enhancement under 18 U.S.C. § 3147 applies, add 3 levels
  to the offense level for the offense committed while on release as if this
  section were a specific offense characteristic contained in the offense guideline
  for the offense committed while on release.
Commentary
Statutory Provision: 18
  U.S.C. § 3147.
Application Notes: 
1. Because 18 U.S.C. § 3147 is an enhancement provision, rather than
  an offense, this section provides a specific offense characteristic to increase
  the offense level for the offense committed while on release. 
2. Under 18 U.S.C. § 3147, a sentence of imprisonment must be imposed
  in addition to the sentence for the underlying offense, and the sentence of
  imprisonment imposed under 18 U.S.C. § 3147 must run consecutively
  to any other sentence of imprisonment. Therefore, the court, in order to comply
  with the statute, should divide the sentence on the judgment form between the
  sentence attributable to the underlying offense and the sentence attributable
  to the enhancement. The court will have to ensure that the "total punishment" (i.e.,
  the sentence for the offense committed while on release plus the sentence enhancement
  under 18 U.S.C. § 3147) is in accord with the guideline range for
  the offense committed while on release, as adjusted by the enhancement in this
  section. For example, if the applicable adjusted guideline range is 30-37 months
  and the court determines "total punishment" of 36 months is appropriate, a
  sentence of 30 months for the underlying offense plus 6 months under 18 U.S.C. § 3147
  would satisfy this requirement.
Background: An enhancement
  under 18 U.S.C. § 3147 may be imposed only after sufficient
  notice to the defendant by the government or the court, and applies only in
  the case of a conviction for a federal offense that is committed while on release
  on another federal charge.
Legislative history indicates that the mandatory nature of the penalties
  required by 18 U.S.C. § 3147 was to be eliminated upon the implementation
  of the sentencing guidelines.  "Section 213(h) [renumbered as §200(g)
  in the Crime Control Act of 1984] amends the new provision in title I of this
  Act relating to consecutive enhanced penalties for committing an offense on
  release (new 18 U.S.C. § 3147) by eliminating the mandatory nature
  of the penalties in favor of utilizing sentencing guidelines."  (Senate Report
  98-225 at 186). Not all of the phraseology relating to the requirement of a
  mandatory sentence, however, was actually deleted from the statute. Consequently,
  it appears that the court is required to impose a consecutive sentence of imprisonment
  under this provision, but there is no requirement as to any minimum term. This
  guideline is drafted to enable the court to determine and implement a combined "total
  punishment" consistent with the overall structure of the guidelines, while
  at the same time complying with the statutory requirement. Guideline provisions
  that prohibit the grouping of counts of conviction requiring consecutive sentences
  (e.g., the introductory paragraph
  of
  §3D1.2; §5G1.2(a)) do not apply to this section because 18 U.S.C. § 3147
  is an enhancement, not a count of conviction.
