that an injunction issue whenever the Coal Leasing Act is violated, but also that Congress has mandated that the injunction void all activities, such as the leasing of federal land containing coal, undertaken in violation of the Act. The Secretary and the intervenors disagree and contend that Congress has not balanced the equities under the statute and that, therefore, the district retained its traditional equitable power to vindicate the objectives and requirements of the statute. Amoco Production Co. v. Village of Gambell, — U.S. —, 107 S.Ct. 1396, 94 L.Ed.2d 642 (1987); Weinberger v. Romero-Barcelo, 456 U.S. 305, 102 S.Ct. 1798, 72 L.Ed.2d 91 (1982).
Hill, Romero-Barcelo, and Village of Gambell provide significant guidance in deciding whether Congress has balanced the equities under the statute and mandated an injunction. In Hill, the Court stated that generally courts retain discretion to fashion appropriate relief unless Congress has clearly demonstrated explicitly or implicitly that it has balanced the equities and mandated an injunction. See Hill, 437 U.S. at 173-74, 98 S.Ct. at 2291-92. In Romero-Barcelo, the plaintiff sued the Secretary of Defense and claimed that the Navy, while using an island off Puerto Rico’s coast for weapons training, violated the Federal Water Pollution Control Act, 33 U.S.C. § 1251. The plaintiff argued that, as in Hill, Congress had balanced the equities under that act and, therefore, that the district court had to issue an injunction once it found the government in violation. The Court disagreed, stating that the “purpose and language of the statute under consideration in Hill, not the bare fact of a statutory violation, compelled” the conclusion that an injunction was mandatory in Hill. Romero-Barcelo, 456 U.S. at 314, 102 S.Ct. at 1804. In contrast, the Court pointed out that the statutory scheme now before it demonstrated that Congress did not intend to limit a court’s remedy to an immediate prohibiting injunction upon finding a violation. Id. at 315-19, 102 S.Ct. at 1804-07. The Court concluded that the district court retained the equitable discretion to grant or deny injunctive relief. Id. at 320, 102 S.Ct. at 1807.
In Village of Gambell, the plaintiff argued that the defendant violated the Alaska National Interest Lands Conservation Act, 16 U.S.C. § 1320, when it sold oil and gas leases for federally owned lands on Alaska’s continental shelf, and, that, therefore, it was automatically entitled to injunc-tive relief. The Court examined the statutory scheme and held that the act did not remove the district court’s traditional equitable power in fashioning a remedy once a violation is established. Village of Gambell, 107 S.Ct. at 1403.
We accordingly focus “on the underlying substantive policy” that Congress designed the statute to effect. Village of Gambell, 107 S.Ct. at 1403. Nothing in the Act indicates that Congress intended to restrict the court’s jurisdiction in equity. “The basic purpose” of the Act is “to provide a more orderly procedure for the leasing and development” of coal the United States owns, while ensuring its development “in a manner compatible with the public interest.” H.R.Rep. No. 681, 94th Cong., 1st Sess. 8 (1975), reprinted in 1976 U.S.Code Cong. & Admin.News 1943, 1943. Congress’s underlying substantive policy concern was to develop the coal resources in an environmentally sound manner. This purpose lays as much stress on the developing the coal resources as it does on the environmental effects of development. It is a purpose served without imposing an iron rule that an injunction will issue if the Act is violated. As Congress has not divested the district courts of their traditional equitable power, it logically follows that district courts have the discretion to deny or grant injunctive relief. See Romero-Barcelo, 456 U.S. at 320, 102 S.Ct. at 1807.
4. The Tribe argues that the district court abused its discretion in amending the injunction to suspend, rather than to void, the leases. The Tribe contends that merely suspending the leases leads to the danger of “bureaucratic commitment” to the leases. See Massachusetts v. Watt, 716 F.2d 946 (1st Cir.1983). The Tribe essentially contends that the danger of bureaucratic commitment presents a type of irreparable
