The text
(a)(1) Debarment shall be for a period commensurate with the seriousness of the cause(s). Generally, debarment should not exceed 3 years, except that—
(i) Debarment for violation of the provisions of 41 U.S.C. chapter 81, Drug-Free Workplace (see 26.505) may be for a period not to exceed 5 years;
(ii) Debarments under 9.406-2(b)(2) shall be for 1 year unless extended pursuant to paragraph (b) of this section; and
(iii) Debarments under 9.406-2(b)(1)(vii) shall be for a period of not less than 2 years, inclusive of any suspension period, if suspension precedes a debarment (see paragraph (a)(2) of this section).
(2) If suspension precedes a debarment, the suspension period shall be considered in determining the debarment period.
(b) The suspending and debarring official may extend the debarment for an additional period, if that official determines that an extension is necessary to protect the Government's interest. However, a debarment may not be extended solely on the basis of the facts and circumstances upon which the initial debarment action was based. Debarments under 9.406-2(b)(2) may be extended for additional periods of one year if the Secretary of Homeland Security or the Attorney General determines that the contractor continues to be in violation of the employment provisions of the Immigration and Nationality Act. If debarment for an additional period is determined to be necessary, the procedures of 9.406-3 shall be followed to extend the debarment.
(c) The suspending and debarring official may reduce the period or extent of debarment, upon the contractor's request, supported by documentation, for reasons such as—
(1) Newly discovered material evidence;
(2) Reversal of the conviction or civil judgment upon which the debarment was based;
(3) Bona fide change in ownership or management;
(4) Elimination of other causes for which the debarment was imposed; or
(5) Other reasons the suspending and debarring official deems appropriate.
