This case involves government delay in promulgating water pollution guidelines and industry delay in implementing pollution control technology. Each party asserts that its delay was justified and did not excuse the other’s lack of diligence.
Specifically, the federal Environmental Protection Agency (EPA) and ITT Rayonier (Rayonier) dispute the meaning of a footnote attached to the discharge permit for Rayonier’s pulp mill in Port Angeles, Washington, on the Straits of Juan de Fuca. Because this precise issue was previously litigated in state courts and determined favorably to Rayonier, we find the EPA collaterally estopped from asserting a contrary position in this enforcement action in federal court.
BACKGROUND
In 1972 Congress established the National Pollutant Discharge Elimination System (NPDES) under § 402 of the Federal Water Pollution Control Act (FWPCA). 33 U.S.C. § 1342. Under this system state agencies, pursuant to an approved state program, may issue water pollution discharge permits. In November’ 1973, the EPA approved Washington’s permit program and transferred permit-issuing authority to the Washington Department of Ecology (DOE). See 39 Fed.Reg. 26,061 (1974).
FWPCA authorized issuance of NPDES permits designed to achieve .compliance by July 1,1977, with regulations (effluent limitations) defining “best practicable control technology” (BPT). 33 U.S.C. § 1311(b)(1)(A). 1 The EPA was to establish *999 BPT effluent limitations for the pulp industry by October 1973. 33 U.S.C. § 1314(b).
RAYONIER’S PERMIT
In the summer of 1973 and early in 1974, Rayonier and DOE negotiated the terms of an NPDES permit. Because the EPA had not yet established effluent limitations, the parties incorporated discharge limitations from prior legislation. 2 Contemplating imminent promulgation of guidelines, the parties included footnote f in that section of the permit containing numerical discharge standards for various pollutants:
The biochemical oxygen demand, suspended solids, and pH limitations will be modified to be consistent with the applicable final effluent guidelines when promulgated by the EPA in the Federal Register, or as thereafter modified by final action consequent upon any appeal from such guidelines.
A separate section of the permit set forth the compliance schedule for attaining the permit standards. DOE issued the permit in August 1974 and the EPA did not exercise its veto authority. See 33 U.S.C. § 1342(d)(2).
Disputes arose as to the adequacy of Rayonier’s implementation plans. In November 1975, the EPA advised DOE that, if it did not take action, Rayonier would be a “candidate” for federal enforcement. Doe issued a compliance order in December 1975 which Rayonier appealed to the state Pollution Control Hearings Board.
In February 1976, more than two years after its statutory deadline, the EPA promulgated effluent limitations for pulp mills. 3 Rayonier and other pulp firms immediately challenged those standards in federal court. 4 In its July 1976 hearing before the state pollution control hearings board, Rayonier contended footnote f extended its compliance schedule pending final judicial approval of the EPA’s proposed effluent guidelines. The board disagreed, denied a stay pending judicial review, and ordered Rayonier to meet its permit compliance schedule. This order was stayed pending Rayonier’s appeal to state superior court.
In March 1977, the EPA issued a notice of violation to Rayonier and DOE pursuant to 33 U.S.C. § 1319(a)(1). Three weeks later the state court reversed the hearings board, finding footnote f excused compliance pending judicial approval of final effluent limitations. DOE appealed to the state supreme court, notifying the EPA that it was effectively prevented from further enforcement. In April 1977, the EPA filed its own enforcement action in federal court under 33 U.S.C. § 1319(b), seeking injunctive relief and civil penalties. The July 1, 1977, statutory deadline for attaining best practicable control technology passed with the parties at an impasse.
In October 1977, the district court granted the EPA’s motion for summary judgment on the injunctive phase of the case and ordered immediate compliance with the permit. The court found footnote f to be an unambiguous declaration pertaining only to substitution of standards and not to modification of the compliance schedule.
Pending appeal of the district court’s injunction order, several significant events have transpired. First, the D.C. Circuit upheld the BPT effluent limitations for the pulp industry with one relevant exception.
Weyerhaeuser Co. v. Costle,
The importance of final standards prior to [the expenditure of funds] establishes the natural interdependence of the standards . . . and the compliance schedule .
Finally, pursuant to the district court’s compliance order, Rayonier has installed pollution control equipment provisionally satisfactory to the EPA. Despite Rayonier’s compliance, the appeal is not moot because the district coürt has determined liability and retained jurisdiction to ascertain civil penalties under 33 U.S.C. § 1319(d).
See, e. g., Planned Parenthood of Minn., Inc. v. Citizens for Comm. Action,
As a threshold matter, Rayonier asserts the judgment in the state enforcement action operates to preclude the EPA’s action. It also contends the EPA is barred from bringing the instant action under the doctrines of election of remedies and unclean hands. If these arguments are unavailing, Rayonier urges this court to construe footnote f as modifying its compliance schedule. Because we find the EPA collaterally es-topped from disputing the meaning of footnote f, we need not address remaining issues.
RES JUDICATA/COLLATERAL ESTOPPEL
The district court held, as a matter of law, no privity exists between DOE and EPA for enforcement purposes. For this proposition, the court relied exclusively upon 33 U.S.C. § 1342(i), which provides:
Nothing in this section [pertaining to NPDES] shall be construed to limit the authority of the [EPA] Administrator to take [enforcement] action .
Under the doctrine of res judicata, “a final judgment on the merits bars further claims by parties or their privies based on the same cause of action.”
Montana v. United States,
In the absence of “countervailing statutory policy,” collateral estoppel bars relitigation of factual questions or mixed questions of law and fact. *
See Brown v. Felsen,
1. FWPCA and Collateral Estoppel
Section 1342(i) preserves federal enforcement authority despite state permit-issuing power. It is included in that section of FWPCA implementing the NPDES permit program. The legislative history of
*1001
FWPCA is replete with references to “dual” or “concurrent” enforcement authority.
6
The act has been said to create a “delicate partnership” between state and federal agencies.
Save the Bay, Inc. v. EPA,
The existence of concurrent enforcement powers does not per se negate the application of res judicata principles.
See Ma Chuck Moon v. Dulles,
Section 1342(i) reserves EPA’s authority to bring an enforcement action notwithstanding an approved state permit system with concomitant enforcement powers. Enforcement actions could have been filed concurrently in both state and federal courts. See 33 U.S.C. § 1319(b) (federal); 33 U.S.C.'§ 1342(b)(7) (state). This does not necessarily preclude the operation of collateral estoppel after one action reaches finality-
Although no court has directly addressed the preclusive effect of prior judicial enforcement actions under FWPCA, courts in dicta have assumed the doctrine is not abrogated. See, e.
g., United States v. Pennsylvania Environ. Hrg. Bd.,
Further, it has been suggested that enforcement agencies could invoke res judicata offensively against a second alleged polluter because of its privity relationship with a prior adjudged polluter.
See Reserve Mining v. EPA,
The real question in the context of this suit is the conflict between state and federal courts. Res judicata is a rule promoting harmony and cooperation between courts.
See United States v. Bank of New York Co.,
We do not perceive how the need for uniformity under FWPCA is best promoted by conflicting judicial constructions and repeated agency prosecutions. To extend the Fifth Circuit’s analogy in
Save the Bay v. EPA,
In employment discrimination suits under Title VII of the 1964 Civil Rights Act, 42 U.S.C. § 2000e et seq., several circuits have refused to give collateral estoppel effect to prior decisions by state agencies under state law.
See, e. g., Batiste v. Furnco Constr. Corp.,
These courts have found a countervailing public policy that a plaintiff is not to be deprived of a federal forum to adjudicate employment discrimination claims. Unlike Title VII, FWPCA does not provide a mandatory period of deference to state proceedings. Compare 42 U.S.C. § 2000e-5(c) with 33 U.S.C. § 1319(a).
FWPCA contemplates concurrent enforcement actions. 33 U.S.C. §§ 1319(b), 1342(b)(7). Only if the EPA decides to exercise its enforcement option of issuing a notice of violation to the state agency, rather than- immediately prosecuting, is a waiting period prescribed. The state is given 30 days to commence “appropriate enforcement action.” 33 U.S.C. § 1319(a)(1). Thereafter, FWPCA does not specifically mandate a
de novo
hearing in federal court.
Cf. Chandler
v.
Roudebush,
Unlike successive state and federal employment discrimination actions, state and federal enforcement actions under FWPCA are based on permits issued under a single system. The EPA retains authority to veto state-issued permits. 33 U.S.C. § 1342(d)(2). Further, it may revoke the permit issuing authority of the state agency.
See
33 U.S.C. § 1342(c)(3). Although Title VII may manifest Congressional intent to permit pursuit of independent rights in successive state and federal actions,
Alexander v. Gardner-Denver Co.,
Congress has stated FWPCA does not involve a “delegation” of federal authority. House Conf.Rpt. No. 95-830,95th Cong., 1st Sess., reprinted in [1977] U.S.Code Cong. & Admin.News, pp. 4424, 4479. Although the NPDES state permit program is established under state law and functions “in lieu” of federal authority, the source of the federal/state “partnership” can be traced to a single act of Congress (FWPCA). Regardless whether the state’s enforcement position can be accurately described as a “delegee” of powers, its authority vis a vis NPDES permits is derived from FWPCA and is revocable by the EPA.
For these reasons we do not believe FWPCA manifests countervailing policy reasons to abrogate the doctrine known generically as res judicata. If the EPA is dissatisfied with state enforcement efforts or the lack thereof it can revoke permit-issuing authority or bring an independent action in federal court. Where, as here, a state court has entered a final judgment on an identical issue, the EPA cannot invoke FWPCA to avoid any preclusive effect that judgment may have.
2. Privity
Having determined that FWPCA does not abrogate res judicata principles, we must ascertain if such principles are applicable here.
7
It is not disputed that the same operative facts gave rise to the two actions.
See Johnson v. Dept. of Water & Power of Los Angeles,
*1003
The doctrine of privity extends the conclusive effect of a judgment to nonparties who are in privity with parties to an earlier action. In
Chicago, R.I. & P. Ry. Co. v. Schendel,
Courts are no longer bound by rigid definitions of parties or their privies for purposes of applying collateral estoppel or res judicata.
Jackson v. Hayakawa,
Further, “privy” may include those whose interests are represented by one with authority to do so. See Ma Chuck Moon v. Dulles, supra.
Courts have recognized that a non-party may be bound if a party is so closely aligned with its interests as to be its “virtual representative.”
Aerojet Gen'l Corp. v. Askew,
We find the contention of variance of parties in these enforcement actions to be insubstantial. The interests of DOE and the EPA were identical and their involvement sufficiently similar.
See Jackson v. Hayakawa,
DOE issued its original enforcement order following the EPA’s prompting that absent state action Rayonier was a candidate for federal enforcement. It is undisputed that DOE maintained the same position as the EPA before the state hearings board and state courts.
See ITT Rayonier, Inc. v. Department of Ecology,
In some contexts, the relationship between governmental authorities as public enforcers of ordinances and private parties suing for enforcement as private attorneys general is close enough to preclude relitigation.
Southwest Airlines Co. v. Texas International Airlines, Inc.,
FWPCA vests authority in state agencies to administer the terms of the NPDES program; however, the allocation of authority between state and federal «agencies under FWPCA is far from clear.
Shell Oil Co. v. Train,
In the context of this case, however, we need not find a strict agency relationship. The relationship between DOE and the EPA, however, it may be labeled, is sufficiently “close” under the circumstances to preclude relitigation of the issue already resolved in state court.
*1004
As the permit in question has expired,
9
and the relevant effluent regulations have either received judicial approval or are in the process of completion,
10
this suit may be
sui generis.
The propriety of the state court’s construction of
footnote f
is not before this court. The doctrine of res judicata does not depend on whether the prior judgment was free of error.
Milliken v. Meyer,
The district court judgment is REVERSED.
Notes
. FWPCA’s stated purpose is “to restore and maintain the chemical, physical and biological integrity of the Nation’s waters.” 33 U.S.C. § 1251(a). To achieve that objective, Congress declared, “it is the national goal that the discharge of pollutants into the navigable waters be eliminated by 1985.” Id
FWPCA envisioned a two phase program: (1) achieve best practicable technology (BPT) by July 1, 1977; and (2) achieve best available technology (BAT) by July 1, 1983. The Clean Water Act of 1977, Pub.L. 95-217, changed the BAT requirement to a more flexible “best conventional technology” standard and extended the deadline to July 1, 1984.
The Clean Water Act also amended FWPCA to allow the EPA to grant BPT extensions up to April 1, 1979, for dischargers unable to meet the July 1, 1977, deadline despite good faith efforts. 33 U.S.C. § 1319(a)(5)(B). Rayonier indicated to the district court it could not achieve compliance before June 1979, thus could not qualify for this deadline extension.
Section 402 of FWPCA established NPDES permits as the primary means to enforce effluent limitations. All discharges must be authorized by a permit issued by the EPA or the authorized state agency. A permit transforms “generally applicable effluent limitations and other standards . . . into the obligations (including a time table for compliance) of the individual discharger.”
EPA v. Calif, ex rel. State Water Res. Bd,
. The permit contained discharge limitations for suspended solids, pH and biochemical oxygen demand derived from § 13 of the Rivers and Harbors Act of 1899. 33 U.S.C. § 407.
. These limitations were promulgated in “interim final form.” Final limitations were not issued until January 6, 1977.
.
Weyerhaeuser Co. v. Costle,
. The D.C. Circuit upheld all BPT effluent limitations except biochemical oxygen demand (BOD) for grade dissolving sulfite mills, such as Rayonier’s Port Angeles plant.
Weyerhaeuser v. Costle,
. See e. g., Sen.Rpt. No. 92-414, 92d Cong., 2d Sess., reprinted in [1972] U.S.Code Cong. & Admin.News, pp. 3668, 3675; Id. at 3730.
. Under 28 U.S.C. § 1738, Congress imposed an obligation on federal courts to give full faith and credit to judgments entered by state courts of competent jurisdiction. This ordinarily requires analysis of the res judicata effect of state court proceedings within the state. Our conclusion would be no different were we to apply the Washington law of res judicata under the full faith and credit statute. Traditional claim preclusion is applied in that jurisdiction.
Bordeaux v. Ingersoll Rand Co.,
.
Washington v. EPA
was overruled insofar as it held that the EPA’s veto of a state-issued permit did not give the courts of appeals direct review authority under 33 U.S.C. § 1369.
Crown Simpson Pulp Co. v. Costle,
. Under FWPCA, permits may be issued for a maximum 5 year period. 33 U.S.C. § 1342(b)(1)(B). This court was informed at oral argument that the permit at issue expired on August 29, 1979. The EPA has vetoed DOE’s proposed new permit for Rayonier for failure to incorporate more stringent BOD standards. Apparently, the EPA is considering issuance of a permit pursuant to its authority under 33 U.S.C. § 1342(d)(4).
