§ 4208.3 Abatement.
(a) General. Whenever an eligible employer that has partially withdrawn from a multiemployer plan satisfies the requirements in § 4208.4 for the reduction or waiver of its partial withdrawal liability, it may apply to the plan for abatement of its partial withdrawal liability. Applications shall identify the eligible employer, the withdrawn employer (if different), the date of withdrawal, and the basis for reduction or waiver of its withdrawal liability. Upon receiving a complete 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 partial withdrawal liability under § 4208.4. If the plan sponsor determines that the employer satisfies the requirements for abatement of its partial 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 partial withdrawal liability, the provisions of paragraphs (d) and (e) of this section shall apply.
(b) Determination of abatement. Within 60 days after an eligible employer that partially withdrew from a multiemployer plan applies for abatement in accordance with paragraph (a) of this section, the plan sponsor shall determine whether the employer satisfies the requirements for abatement of its partial withdrawal liability under § 4208.4 and shall notify the employer in writing of its determination and of the consequences of its determination, as described in paragraphs (c) or (d) and (e) of this section, as appropriate. If a bond or escrow has been provided to the plan under § 4208.5 of this part, the plan sponsor shall send a copy of the notice to the bonding or escrow agent.
