§ 4207.3 Abatement.
(a) General. Whenever an eligible employer that has completely withdrawn from a multiemployer plan reenters the plan, it may apply to the plan for abatement of its complete withdrawal liability. Applications shall be filed by the date of the first scheduled withdrawal liability payment falling due after the employer resumes covered operations or, if later, the fifteenth calendar day after the employer resumes covered operations. Applications shall identify the eligible employer, the withdrawn employer, if different, the date of withdrawal, and the date of resumption of covered operations. Upon receiving an application for abatement, the plan sponsor shall determine, in accordance with paragraph (b) of this section, whether the employer satisfies the requirements for abatement of its complete withdrawal liability under § 4207.5, § 4207.9, or a plan amendment which has been approved by PBGC pursuant to § 4207.10. If the plan sponsor determines that the employer satisfies the requirements for abatement of its complete withdrawal liability, the provisions of paragraph (c) of this section shall apply. If the plan sponsor determines that the employer does not satisfy the requirements for abatement of its complete withdrawal liability, the provisions of paragraphs (d) and (e) of this section shall apply.
