(a) In accordance with section 3(d) of the Act, an operator for purposes of this part is "any owner, lessee or other person who operates, controls, or supervises a coal mine or any independent contractor performing services or construction at such mine." In accordance with sections 402(d) and 422(b) of the Act, certain other employers, including those engaged in coal mine construction, maintenance, and transportation, shall also be considered to be operators for purposes of this part. An independent contractor or self-employed miner, construction worker, coal preparation worker, or transportation worker may also be considered a coal mine operator for purpose of this part. It is Congress' intent that any employer of a miner as defined in 725.202(a) shall, to the extent appropriate, be considered an operator for for the purposes of this part, and the provisions of this part shall be construed in accordance with this intent.
(b) (1) In determining which operator or other employer is the employer of a particular miner, primary consideration shall be given to the identity of the employer which is directly responsible for the supervision, operation and control of the mine or mines or other facilities where the miner was employed. However, Congress has made it clear that such supervision or control may be directly or indirectly exercised. Therefore, in appropriate cases where, for example, the individual or business entity most directly connected with the mine site is not capable of assuming liability for the payment of benefits (725.492(d)) or is no longer in business and such individual or business entity is a subsidiary of a parent company, a member of a joint venture, a partner in a partnership, or is 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 an operator for purposes of this part, regardless of the nature of its business activities.
(2) Where a coal mine is leased, and the lease empowers the lessor to make decisions with respect to the terms and conditions under which coal is to be extracted or prepared, such as, but not limited to, the manner of extraction or preparation or the amount of coal to be produced, the lessor may be considered an operator with respect to employees of the lessee. An individual land owner or others who lease coal lands or mineral rights, who have never been coal mine operators or are not in the regular business of leasing coal mines, shall not be considered a coal mine operator in accordance with the terms of this section. Where a lessor previously operated a coal mine, it may be considered an operator with respect to employees of any lessee of such mine, particularly where the leasing arrangement was executed or renewed after the effective date of this part and does not require the lessee to secure benefits provided by the Act.
(3) In any claim in which the liability of a lessor for claims arising out of employment with a lessee is brought into question, the lessee shall be considered primarily liable for the claim, and 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 consideration of the terms and intent of the act and this part.
(4) A former coal mine operator which has become a lessor of coal miner shall be liable for approved claims arising out of coal mine employment with such lessor during the time the lessor was a coal mine operator, if such employment terminated on or after January 1, 1970, and the conditions for liability contained in 725.492 are met.
(c) (1) An independent contractor which performs or performed services or engages or engaged in construction at a mine or preparation or transportation facility may be held liable for the payment of benefits under this part as a coal mine operator with respect to its employees who work or have worked in or around a coal mine or coal preparation or transportation facility in the extraction, preparation, or transportation of coal or in coal mine construction in any period during which such employees were exposed to coal dust during their employment with such contractor. Such contractor's status as an operator shall not be contingent upon the amount or percentage of its work or business related to activities in or around a mine, nor upon the number or percentage of its employees engaged in such activities.
(2) (i) Any individual who works or has worked as a sole proprietor, a partner in a partnership, a member of a family business or who is otherwise self-employed in or around a coal mine or coal preparation or transportation facility in the extraction, preparation, or transportation of coal or in coal mine construction during any period such individual was exposed to coal dust may be considered an operator under this part.
(ii) 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.
(iii) For the purposes of this part, a lessor of a coal mine which leases such mine to a self-employed operator shall be considered the employer of such self-employed operator and its employees if the lease or agreement is executed or renewed after the effective date of this part and such lease or agreement does not require the lessee to guarantee the payment of benefits which may be required under this part.
