29 CFR 4207.10 - Plan rules for abatement.
(a)General rule. Subject to the approval of the PBGC, a plan may, by amendment, adopt rules for the reduction or waiver of complete withdrawal liability under conditions other than those specified in §§ 4207.5 and 4207.9 (c) and (d), provided that such conditions relate to events occurring or factors existing subsequent to a complete withdrawal year. The request for PBGC approval shall be filed after the amendment is adopted. A plan amendment under this section may not be put into effect until it is approved by the PBGC. However, an amendment that is approved by the PBGC may apply retroactively to the date of the adoption of the amendment. PBGC approval shall also be required for any subsequent modification of the amendment, other than repeal of the amendment. Sections 4207.6, 4207.7, and 4207.8 shall apply to all subsequent partial withdrawals after a reduction or waiver of complete withdrawal liability under a plan amendment approved by the PBGC pursuant to this section.

(e)Supplemental information. In addition to the information described in paragraph (d) of this section, a plan may submit any other information that it believes it pertinent to its request. The PBGC may require the plan sponsor to submit any other information that the PBGC determines it needs to review a request under this section.
