If State compliance with clause (1) of this subsection requires an act of the State legislature, the Secretary may extend the period of submission of a State program up to an additional six months. Promulgation and implementation of a Federal program vests the Secretary with exclusive jurisdiction for the regulation and control of surface coal mining and reclamation operations taking place on lands within any State not in compliance with this chapter. After promulgation and implementation of a Federal program the Secretary shall be the regulatory authority. If a Federal program is implemented for a State, section 1272(a), (c), and (d) of this title shall not apply for a period of one year following the date of such implementation. In promulgating and implementing a Federal program for a particular State the Secretary shall take into consideration the nature of that State’s terrain, climate, biological, chemical, and other relevant physical conditions.
