na, 325 U.S. 761, 65 S.Ct. 1515, 89 L.Ed. 1915 (1945).
The issue of whether regulations promulgated under the state’s police power seeking to protect the state’s inhabitants from environmental pollution may he applied to those engaged in interstate commerce was before the Supreme Court in Huron Portland Cement Co. v. City of Detroit, 362 U.S. 440, 80 S.Ct. 813, 4 L.Ed.2d 852 (1960). The City had adopted a smoke abatement ordinance and sought to enforce the penal provisions of that ordinance against shippers admittedly engaged in interstate commerce.
The Court discussed without “extended discussion” the contention that such an ordinance was precluded by the dormant Commerce Clause.
The Detroit ordinance did not discriminate against interstate commerce and there was no showing that national uniformity was required to prevent inconsistent local regulations.
The Maine Act does not discriminate in favor of the intrastate commerce and plaintiffs have advanced nothing to show that compliance with Maine’s regulations will place plaintiffs in the dilemma facing the truckers in Bibb v. Navajo Freight Lines, Inc., 359 U.S. 520, 79 S.Ct. 962, 3 L.Ed.2d 1003 (1959).
The issue once again becomes a question of whether or not the regulations advanced by the state are in conflict with federal law. In Huron the Court found that Congress recognized the primary responsibility of state and local governments to prevent air pollution. The federal laws did not purport to be an exercise of police power.
This situation now before us is similar.
Congress has, in the Water Quality Improvement Act, exercised police power but it has also specifically declared that it did not intend to preempt the field.
In the light of this Congressional encouragement of state action, and because the regulations and liability imposed upon oil terminals under the Act are not otherwise unconstitutional, we hold that no conflict exists between the Act and federal law.
Since neither the license fees nor the regulations and liability provisions of the Act constitute an impermissible burden, plaintiffs’ challenge under the Commerce Clause must fail.
VIII Admiralty
Plaintiffs contend the Act unconstitutionally abridges Article III, Section 2, Clause 1, of the United States Constitution. That clause provides:
“The judicial Power shall extend . . to all Cases of admiralty and maritime jurisdiction.”
It is asserted that the Act “purports to make radical changes in substantive maritime law.”
The Admiralty Clause does not permit either Congress or the States to deprive the Federal Courts of admiralty jurisdiction. Panama R.R. Co. v. Johnson, 264 U.S. 375, 44 S.Ct. 391, 68 L.Ed. 748 (1924). This Court has recognized as much in Warren v. Kelley, 80 Me. 512, 15 A. 49 (1888). See also, Berry v. M. F. Donovan & Sons, 120 Me. 457, 115 A. 250 (1921).
38 M.R.S.A. § 551 (2)D provides that claims arising under the Act shall be recoverable only in the manner provided by the Act and that the remedies provided to those harmed by oil spills under the Act are to be “exclusive.”
The doctrine of presumptive constitutionality of statutory enactments is given full effect in challenges based on the Admiralty Clause. Huron Portland Cement Co. v. Detroit, 362 U.S. 440, 80 S.Ct. 813, 4 L.Ed.2d 852 (1960); Davis v. Dept. of Labor, 317 U.S. 249, 63 S.Ct. 225, 87 L.Ed. 246 (1942).
