Petitioners in these consolidated cases challenge the authority of the Environmental Protection Agency [hereinafter EPA] under the Clean Water Act, as amended, 33 U.S.C. § 1251, et seq., to regulate the discharge of pollutants from uranium mining and milling facilities into gullies or “arroyos.”
Quivira Mining Company [formerly Kerr-McGee Nuclear Corp.] is contesting EPA permits (National Pollution Discharge Elimination System Permits) to two of its uranium milling or mining facilities near Grants, New Mexico. Those facilities are referred to as Ambrosia Lake, which discharges pollutants into Arroyo del Puerto under Permit No. NM0020532, and Lee Mines, which discharges pollutants into San Mateo Creek under Permit No. NM0028207. Homestake Mining Company [formerly United Nuclear Homestake Partners] contests Permit No. NM0020389 regulating its discharges into Arroyo del Puer-to. The companies contend that Arroyo del Puerto and San Mateo Creek are not “waters of the United States,” and therefore the EPA has no jurisdiction under the Clean Water Act to require permits authorizing discharges into these waters.
*128 This appeal is from two written determinations of the EPA Administrator [hereinafter Administrator] to deny review, which are embodied in orders dated August 5, 1983. There are two issues before the court. First, the court must determine how much deference, if any, to give to the findings of the Administrator. Petitioners contend that the court should evaluate the record independently, giving no special weight to the factual determinations of the agency, because the agency’s determinations of the facts are “jurisdictional.” The EPA contends that the record is the product of an adjudicatory hearing and the court must find the agency action to be “unsupported by substantial evidence” before such action can be set aside. The second issue is whether the discharges are subject to regulation as discharges into the waters of the United States.
The Clean Water Act does not set forth standards for reviewing the EPA’s decision, so this court must look to the Administrative Procedure Act for guidance. 5 U.S.C. § 701,
et seq.; Avoyelles Sportsmen’s League, Inc. v. Marsh,
Petitioners contend that when the agency’s determinations of fact are “jurisdictional,” the court must independently assess the record, giving no special weight to the determinations of the agency. See
Crowell v. Benson,
We agree that the court must engage in a substantial inquiry and an in-depth review of the record.
Chrysler Corp. v. Dept. of Transportation,
Petitioners’ argument would require that in every case involving the issuance of an EPA permit to discharge pollutants the adjudicatory hearings and special findings of the Administrator would be entitled to no special weight. Such a result would contradict the clear meaning of the Administrative Procedure Act and would deprive the appellate courts of the expertise of the agency in determining such matters. 2
*129 Viewed in the light of the substantial evidence test, the court finds that both the Arroyo del Puerto and the San Mateo Creek flow for short distances from the discharge points. Although neither the Arroyo del Puerto nor the San Mateo Creek is navigable-in-fact, surface flow occasionally occurs, at times of heavy rainfall, providing a surface connection with navigable waters independent of the underground flow. Additionally, the waters of the Arroyo del Puerto and the San Mateo Creek soak into the earth’s surface, become part of the underground aquifers, and after a lengthy period, perhaps centuries, the underground water moves toward eventual discharge at Horace Springs or the Rio San Jose.
It is the national goal of the Clean Water Act to eliminate the discharge of pollutants into navigable waters. 33 U.S.C. § 1251(a)(1). The term “navigable waters” means “the waters of the United States, including the territorial seas.” In
United States v. Earth Sciences, Inc.,
The extent of the Clean Water Act’s coverage of discharges of pollution is illustrated by a review of some of the cases which have been before the United States Court of Appeals for the Tenth Circuit. In
Ward v. Coleman,
This court’s findings in Earth Sciences and Texas Pipe Line compel a finding herein affirming the decision of the EPA. Substantial evidence here supports the Administrator’s findings that both the Arroyo del Puerto and San Mateo Creek are waters of the United States. Substantial evidence before the Administrator supports his finding that during times of intense rainfall, there can be a surface connection between the Arroyo del Puerto, San Mateo Creek and navigable-in-fact streams. Further, the record supports the finding that both the Arroyo del Puerto and San Mateo Creek flow for a period after the time of discharge of pollutants into the waters. Further, the flow continues regularly through underground acquifers fed by the surface flow of the San Mateo Creek and Arroyo del Puerto into navigable-in-fact streams. The court finds that the impact on interstate commerce is sufficient enough to satisfy the commerce clause. And, as noted above, it was the clear intent of Congress to regulate waters of the United States to the fullest extent possible under the commerce clause.
The decision of the Administrator is AFFIRMED.
Notes
. See
Estep v. United States,
. Petitioners emphasize language in
Avoyelles Sportman's League, Inc. v. Marsh,
The court did not have before it the question of what standard of review would be employed when the agency fact-finding was determinative *129 of the "existence of agency jurisdiction.” The supposed implications of the language of Avo-yelles are not binding on the court. The distinction attempted to be drawn by petitioners between the "extent” of jurisdiction and the "existence” of jurisdiction is a distinction without a difference. In the instant case, the question is one of both the existence and the extent of agency jurisdiction. Petitioners concede that the EPA has jurisdiction over discharges of pollutants into the waters of the United States. Determination of whether certain water is a "water of the United States” is certainly a question going to the extent of the EPA’s jurisdiction. In this case, under our limited facts, the question is also determinative of the existence of jurisdiction.
. The Constitution of the United States authorizes the federal government to "regulate Commerce ... among the several states." U.S. Const., Art. I, § 8. Congress has plenary authority to regulate commerce falling within the grant. See
