Plaintiffs below, an association of owners and operators of tugboats and other vessels responsible for the movement of the bulk of barge traffic in New York and the adjacent states, brought suit in the United States District Court for the Westezm District of New York, seeking declaratory and injunctive relief against the enforcement of New York Navigation Law § 33-c (McKinney Supp. 1972), McKinney’s Consol.Laws, c. 37. That statute prohibits, inter alia, the discharge of sewage into the waters of New York, and requires that marine toilets be equipped with a pollution control device, designed for either the treatment or holding of sewage. Judge Harold P. Burke denied plaintiffs’ request for a three-judge court and dismissed the complaint, holding that there was no federal subject-matter jurisdiction, that no substantial constitutional question was presented, and that, in any event, federal courts should abstain until the New York judiciary had an opportunity to interpret section 33-c. We reverse, and remand for the convening of the statutory three-judge court.
Plaintiffs’ attack upon section 33-c is a wholesale one. In the main, they contend that section 33-c constitutes an impermissible burden upon interstate commerce. They assert that they are faced with a multiplicity of conflicting pollution standards in the several states and Canadian provinces surrounding New York; that no adequate onshore facilities exist for pumping out sewage; and that present on-board treatment methods involve the use of chemicals which az-e themselves pollutants. Plaintiffs also claim that the Federal Water Quality Improvement Act, 33 U.S.C. § 1151 et seq., evidences a Congressional intent to preempt the field, and that they should not be put to the significant expense of complying with section 33-c when forthcoming federal standards may require wholly different equipment. Plain *421 tiffs further attack the statute as unconstitutionally vague, as a denial of Fourteenth Amendment equal protection, and as an unconstitutional state interference with uniform maritime law.
After receiving a number of affidavits and exhibits from both sides, Judge Burke held a hearing on motions for temporary injunctive relief. At that time, defendants renewed a motion to dismiss the complaint. In a memorandum dated January 12, 1972, Judge Burke denied the motions for injunctive relief and granted the motion to dismiss.
Noting that admiralty jurisdiction v/ill not support a claim for injunctive relief,

Khedivial Line, S.A.E. v. Seafarers’ Int’l Union,
Given the jurisdictional basis for the suit, and the fact that plaintiffs clearly seek injunctive relief against the enforcement of a state statute on the grounds of unconstitutionality, a 28 U.S.C. § 2281 three-judge district court is mandated if the constitutional attack is not insubstantial. Idlewild Bon Voyage Liquor Corp. v. Epstein,
According to the district court opinion,
Defendants, perceiving the chief thrust of both Lake Carriers’ and the present ease to be on the Commerce Clause issue, seek to distinguish the New York law from the Michigan one. They claim that since section 33-c (1) (a) exempts from its coverage “passenger or cargo-carrying vessels subject to the Quarantine Regulations of the United States Public Health Service,” its impact is wholly intrastate. Consequently, even accepting the substantiality of the Lake Carriers’ attack, they characterize the present case as frivolous.
While this distinction may make resolution of this controversy easier than
Lake Carriers’,
it does not make the complaint here insubstantial. First, section 3(1) of the Michigan law, to which a large measure of the
Lake Carriers’
vagueness argument was directed, reads virtually
in haec verba
with section 33-e (2) (a). Both prohibit the discharge of materials “which render the water unsightly, noxious or otherwise unwholesome so as to be detrimental to the public health or welfare or to the enjoyment of the water for recreational purposes.” Even assuming that the coverage of the New York statute is wholly intrastate in nature, the vagueness argument remains, and the Supreme Court strongly implied, through its decision to abstain,
In light of the Lake Carriers’ case, which even the minority saw as involving “important” federal questions, 6 we cannot say that the issues presented here, however arguably distinguishable the statutes involved, are so insubstantial as to warrant dismissal of the complaint. 7 A three-judge court should have been convened.
There remains the question of abstention. While a three-judge court may well find
Lake Carriers’
persuasive authority on the point, the decision to abstain is for the three-judge court, not for the single judge. Abele v. Markle,
Consequently, we reverse the judgment below, and remand for the convening of a three-judge court, pursuant to 28 U.S.C. § 2281, to consider the entire complaint, including any Supremacy Clause issues.

Notes
. It is clear, however, that admiralty jurisdiction will allow the granting of a declaratory judgment. Admiralty R. 59,
. We recognize that the hoary proscription of The Eclipse,
. The Michigan statute was enacted as part of the Michigan Watercraft Pollution Control Act of 1970, Mich.Comp. Laws Ann. § 323.331 et seq. (Supp. 1971). We note, but in no way find dispositive, the fact that despite the distinctions now urged upon us, the Michigan suit so interested the Attorney General of New York that he filed an amicus curiae brief before the Supreme Court.
. It is true that the Supreme Court noted some uncertainty over whether the discharge of even treated sewage was prohibited by the Michigan law.
. There exists at least some surface uncertainty about whether the plaintiff’s vessels are at all covered by the Quarantine Regulations, 42 C.F.R. § 72.1 et seq. First, section 72.1 (i) (2) excludes from the definition of interstate traffic the movement of any conveyance solely for the purpose of transporting property to and from a foreign country. Thus, to the extent that plaintiffs operate on the Great Lakes between Canada and the United States, they are possibly without the Regulations. Moreover, the definition of vessel excludes both “Tugs which operate only locally in specific harbors and adjacent waters,” section 72.1(o) (2), and “Barges without means of self-propulsion,” section 72.1 (o) (3).
