Opinion by
President Judge Crumlish, Jr.,In this consolidated action, the Petitioners1 have filed petitions and amended petitions for review in the the nature of complaints in equity2 seeking to enjoin the Respondents3 from submitting or resubmitting a state program of surface coal mining regulation to the Secretary of the United States Department of the Interior (Federal Secretary) in accordance with the Federal Surface Mining Conservation and Reclamation Act of 1977 (SMCRA).4 The Respondents have filed preliminary objections. We dismiss the amended petitions as moot.
Shortly after SMCRA’s passage, the Pennsylvania General Assembly enacted a number of laws regulat*492ing coal mining in the Commonwealth.5 In addition, a comprehensive set of implementing regulations was prepared and subsequently approved by the Environmental Quality Board (EQB). The Petitioners requested this Court 'to, inter alia, enjoin the Department of Environmental Resources (DER) from: 1) submitting or resubmitting to the federal government a state surface mining program as provided for under -SMCRA; 2) submitting implementing regulations to the EQB; and 3) taking further action to enforce a permanent state surface mining program.
By order of ¡this Court dated November 26, 1980, Respondents were enjoined from submitting to the federal government a revised regulatory program6 “until such time that the judicial challenges to the Surface Mining and Reclamation Act . . . and regulations promulgated thereunder are finally adjudicated but in no event longer than (1) one year. ...” This injunction was subsequently modified to prohibit .the Respondents from enforcing a state program of surface mining regulation identical to and based upon SMCRA, the constitutionality of which was then on appeal to the United States Supreme Court. Following the expiration of the preliminary injunction, the *493Commonwealth, on January 25, 1982, submitted to the Federal Secretary revised statutes and regulations as part of its program resubmission. On July 30, 1982, the Commonwealth was granted primary jurisdiction to administer its coal mining regulatory program.7
There is no longer a judicable controversy. The constitutionality of SMCRA has been litigated.8 The Commonwealth has been granted primacy, hence there is no longer the threat of confusion or undue burden allegedly associated with joint federal and state regulation. Finally, .the Petitioners’ request has been satisfied: one year’s breathing room for Pennsylvania’s coal mining industry. No actual controversy still exists; thus, the amended petitions for review must be dismissed as moot.

An overview of SMCRA and the federal-state regulatory scheme is provided by the United States Supreme Court in Hodel v. Virginia Surface Mining and Reclamation Association, 452 U.S. 264 (1981). Basically, SMCRA, which establishes a comprehensive set of minimum nationwide mining control regulations, affords the states the opportunity to assume permanent regulatory authority (that is, primacy) over surface coal mining operations on non-federal lands within their borders. A state is granted primacy when it receives approval from the Federal Secrtary of a proposed permanent regulatory program.
The Commonwealth had originally submitted a program proposal but it had been rejected by -the Federal Secretary on October 22, 1980. Under SMCRA, the proposal could be amended and resubmitted.
