(1) In determining the identity of a responsible operator under this part, the terms “employ” and “employment” shall be construed as broadly as possible, and shall include any relationship under which an operator retains the right to direct, control, or supervise the work performed by a miner, or any other relationship under which an operator derives a benefit from the work performed by a miner. Any individuals who participate with one or more persons in the mining of coal, such as owners, proprietors, partners, and joint venturers, whether they are compensated by wages, salaries, piece rates, shares, profits, or by any other means, shall be deemed employees. It is the specific intention of this paragraph to disregard any financial arrangement or business entity devised by the actual owners or operators of a coal mine or coal mine-related enterprise to avoid the payment of benefits to miners who, based upon the economic reality of their relationship to this enterprise, are, in fact, employees of the enterprise.

(2) The payment of wages or salary shall be prima facie evidence of the right to direct, control, or supervise an individual's work. The Department intends that where the operator who paid a miner's wages or salary meets the criteria for a potentially liable operator set forth in § 725.494, that operator shall be primarily liable for the payment of any benefits due the miner as a result of such employment. The absence of such payment, however, will not negate the existence of an employment relationship. Thus, the Department also intends that where the person who paid a miner's wages may not be considered a potentially liable operator, any other operator who retained the right to direct, control or supervise the work performed by the miner, or who benefitted from such work, may be considered a potentially liable operator.

(1) In any case in which an operator may be considered a successor operator, as determined in accordance with § 725.492, any employment with a prior operator shall also be deemed to be employment with the successor operator. In a case in which the miner was not independently employed by the successor operator, the prior operator shall remain primarily liable for the payment of any benefits based on the miner's employment with the prior operator. In a case in which the miner was independently employed by the successor operator after the transaction giving rise to successor operator liability, the successor operator shall be primarily liable for the payment of any benefits.

(2) In any case in which the operator which directed, controlled or supervised the miner is no longer in business and such operator was a subsidiary of a parent company, a member of a joint venture, a partner in a partnership, or was substantially owned or controlled by another business entity, such parent entity or other member of a joint venture or partner or controlling business entity may be considered the employer of any employees of such operator.

(3) In any claim in which the operator which directed, controlled or supervised the miner is a lessee, the lessee shall be considered primarily liable for the claim. The liability of the lessor may be established only after it has been determined that the lessee is unable to provide for the payment of benefits to a successful claimant. In any case involving the liability of a lessor for a claim arising out of employment with a lessee, any determination of lessor liability shall be made on the basis of the facts present in the case in accordance with the following considerations:

(4) A self-employed operator, depending upon the facts of the case, may be considered an employee of any other operator, person, or business entity which substantially controls, supervises, or is financially responsible for the activities of the self-employed operator.
