Any State which desires to do so may enter into and participate in an agreement under this section with the Secretary of Labor (in this section referred to as the “Secretary”). Any State which is a party to an agreement under this section may, upon providing 30 days’ written notice to the Secretary, terminate such agreement.
An agreement under this section shall not apply (or shall cease to apply) with respect to a State upon a determination by the Secretary that the method governing the computation of regular compensation under the State law of that State has been modified in a manner such that the number of weeks (the maximum benefit entitlement), or the average weekly benefit amount, of regular compensation which will be payable during the period of the agreement (determined disregarding any Federal Pandemic Unemployment Compensation or Mixed Earner Unemployment Compensation) will be less than the number of weeks, or the average weekly benefit amount, of the average weekly benefit amount of regular compensation which would otherwise have been payable during such period under the State law, as in effect on January 1, 2020.
Sums payable to any State by reason of such State’s having an agreement under this section shall be payable, either in advance or by way of reimbursement (as determined by the Secretary), in such amounts as the Secretary estimates the State will be entitled to receive under this section for each calendar month, reduced or increased, as the case may be, by any amount by which the Secretary finds that his estimates for any prior calendar month were greater or less than the amounts which should have been paid to the State. Such estimates may be made on the basis of such statistical, sampling, or other method as may be agreed upon by the Secretary and the State agency of the State involved.
The State agency shall recover the amount to be repaid, or any part thereof, by deductions from any Federal Pandemic Unemployment Compensation or Mixed Earner Unemployment Compensation payable to such individual or from any unemployment compensation payable to such individual under any State or Federal unemployment compensation law administered by the State agency or under any other State or Federal law administered by the State agency which provides for the payment of any assistance or allowance with respect to any week of unemployment, during the 3-year period after the date such individuals received the payment of the Federal Pandemic Unemployment Compensation or Mixed Earner Unemployment Compensation to which they were not entitled, in accordance with the same procedures as apply to the recovery of overpayments of regular unemployment benefits paid by the State.
The monthly equivalent of any Federal pandemic unemployment compensation paid to an individual under this section shall be disregarded when determining income for any purpose under the programs established under titles XIX and title XXI  of the Social Security Act (42 U.S.C. 1396 et seq., 1397aa et seq.).
