ORDER
This case is presently before the Court on Defendant’s Motion for Partial Summary Judgment [15], Plaintiffs Motion for Partial Summary Judgment [27], and Plaintiffs Motion to Amend Complaint [33]. The Court has reviewed the record and the arguments of the parties and, for the reasons set out below, concludes that the motion to amend should be granted and both motions for summary judgment should be denied.
*692 BACKGROUND
Plaintiff, the United States of America, brought this case as a civil enforcement action pursuant to section 309 of the Clean Water Act (“CWA”), 33 U.S.C. § 1319, seeking injunctive relief and civil penalties against Defendant, Windward Properties, Inc. (“Windward”), for five alleged violations of the CWA at Windward’s 3400 acre real estate development in Alpharetta, Georgia. All five violations involve the unpermitted discharge of dredged or fill materials into three streams at the Windward site (Caney Creek, Big Creek, and Camp Creek) and their adjacent wetlands in violation of sections 301 and 404 of the CWA, 33 U.S.C. §§ 1311 and 1344. Count I of the Complaint, which is the subject of Defendant’s current motion for summary judgment, alleges violations by Windward between 1979 and 1982 during construction of the Lake Windward Dam. (Compl. ¶¶ 8-25). 1
DISCUSSION
A. Plaintiff’s Motion to Amend
Plaintiff has moved to amend its Complaint in this action to add Mobil Land Development Corporation (Georgia) as a defendant and to make technical changes to its factual allegations. The Federal Rules of Civil Procedure provide that leave to amend a complaint should be “freely given when justice so requires.” Fed.R.Civ.P. 15(a). “Courts have interpreted [amendment] provisions liberally, in line with the Federal Rules’ overall goal of resolving disputes, insofar as possible, on the merits and in a single judicial proceeding.”
Spartan Grain & Mill Co. v. Ayers,
Defendant expresses concern that amendment of the Complaint will prolong this action unnecessarily. Plaintiff assures the Court, however, that the amendment will cause no delay in this proceeding, (Mem. in Supp. of Pl.’s Mot. to Amend at 7), and the Court will hold Plaintiff to this assurance. Accordingly, in light of the fact that consideration of the above-mentioned factors does not convince the Court that a substantial reason exists to deny Plaintiffs motion, the Court concludes that justice requires allowing Plaintiff to amend its Complaint.
B. Defendant’s Motion for Partial Summary Judgment
Defendant has moved for summary judgment as to Count I on two grounds. First, Defendant asserts that the action is barred by the statute of limitations. (Br. in Supp. of Mot. for Summ.J. [Def.’s Br.] at 11-29). Alternatively, Defendant argues that the action is barred by the doctrine of laches. (Id. at 29-49).
1. Statute of Limitations
The parties apparently agree that this action is governed by 28 U.S.C. § 2462, which provides that an action “shall not be entertained unless commenced within five years from the date when the claim first accrued *693 ...” 3 Both parties also agree that the critical question in this case is when the Government’s claim “accrued.” Defendant asserts that a CWA claim accrues on the date of the violation—-in this case, not later than March 1982—and, as a result, Plaintiffs claim is barred by the statute of limitations as this action was not filed until February 14, 1991. Plaintiff, on the other hand, raises three arguments in opposition to the motion for summary judgment. First, the Government asserts that the claim did not accrue until Defendant’s unlawful activities were discovered. (PL’s Mem. in Opp’n to Mot. for Summ.J. [PL’s Mem.] at 9). Second, Plaintiff argues that Windward’s unlawful actions constitute an ongoing violation. (Id. at 16). Finally, Plaintiff alleges that the statute of limitation does not apply to the Government’s request for injunctive relief. (Id. at 22).
a. Statutes of limitation and injunctive relief
L3] As an initial matter, the Court must determine whether § 2462 applies at all to Plaintiffs request for injunctive relief. Plaintiff argues that, because that section applies only to actions “for the enforcement of any civil fine, penalty or forfeiture,” it does not apply to requests for injunctive relief. (Pl.’s Mem. at 22-23). The Court concludes, however, that the weight of authority dictates a contrary result. The majority of courts that have considered the question, including the United States Supreme Court, have held that when legal and equitable relief are available concurrently
(i.e.,
when an action at law or equity could be brought on the same facts), “equity will withhold its relief ... where the applicable statute of limitations would bar the concurrent legal remedy.”
Cope v. Anderson,
b. Accrual of the Government’s claim
Defendant asserts that Plaintiffs claim in Count I accrued not later than March 1982 (the last date on which an alleged discharge of a pollutant into the waters of the United States occurred in connection with the construction of the Lake Windward Dam) and, as a result, the claim is barred by the five year statute of limitations. (Def.’s Br. at 19). As its initial argument in opposition, Plaintiff asserts that its claim did not accrue until the Government discovered Defendant’s unlawful activities. (Pl.’s Mem. at 9).
*694
It appears that the majority of courts that have interpreted § 2462 in the context of alleged violations of the CWA have adopted some type of “discovery rule” under which the claim does not accrue until the Plaintiff knew (or, perhaps, reasonably should have known) of the violation.
5
The initial CWA cases in which a discovery rule was adopted involved actions brought to enforce effluent limitations against National Pollution Discharge Elimination System (“NPDES”) permit holders.
6
In
Atlantic States Legal Found, v. Al Tech Specialty,
Several subsequent CWA cases that dealt with the time of accrual for státute of limitations purposes addressed actions which, like the present proceeding, involved alleged violations due to the discharge of dredge or fill material without a permit. In
North Carolina Wildlife Fed’n v. Woodbury (“NCWF”),
29 Env’t Rep.Cas. (BNA) 1941, 1944,
It appears to the Court that implementation of a discovery rule in CWA actions is grounded on a number of valid policy concerns. The objective of the CWA is to “restore and maintain the chemical, physical, and biological integrity of the Nation’s waters” in order to “provide! ] for the protection and propagation of fish, shellfish and wildlife ...” 33 U.S.C. § 1251(a)
&
(a)(2). Protection of wetlands clearly plays a significant role in achieving this objective, as wetlands filter and purify water, prevent flooding and erosion by slowing the flow of surface runoff into lakes, rivers, and streams, support such significant natural biological functions as food chain production, and provide general habitat and nesting, spawning, rearing, and resting sites for aquatic species.
United States v. Riverside Bayview Homes, Inc.,
Defendant asserts, however, that the discovery rule should' be viewed as a narrow exception to the general rule that the limitations period begins to run at the time of violation. Accordingly, Defendant argues that, notwithstanding the extension of the *695 discovery rule to dredge/fill violations in the NCWF and Hobbs cases, the discovery doctrine should be limited to NPDES cases and not extended to dredge/fill violations. (Pl.’s Br. at 20-25). Defendant’s principle rationale appears to be that dredge/fill violations, unlike NPDES violations, are “generally overwhelmingly obvious and easily observed” and, as a result, a discovery rule is not necessary. (Id. at 22).
The Court does not find this rationale convincing. Although it may be true that some dredge/fill violations are easily observed, many other violations,may not be easily detected. As the Government notes, the typical § 404 violation involves the unpermitted filling of a wetland, after which the former wetland resembles uplands to the naked eye. In some situations detection of such a violation may be as difficult as discovery of a NPDES violation. Moreover, as Plaintiff also points out, in NPDES situations the Government is already on notice due to the permitting and reporting process that discharges are occurring, while the typical § 404 violation occurs without a permit or report by the violator, arguably making detection more difficult. At any rate, the Court concludes that, to the extent that a given dredge/fill violation is easier to detect than a NPDES violation, this fact is taken into account by the objective nature of the discovery rule adopted by the Court (see infra). That is, if the violation is easily detectible, then the Government reasonably should have known of its presence sooner and, as a result, the limitations period will begin running sooner. Accordingly, the Court concludes that some type of discovery rule is appropriate in this case.
Plaintiff would apparently have the Court adopt a rule which provides that a CWA claim does not accrue until the Government actually discovers the violation. (Pl.’s Mem. at 9). In a different context, however, the Eleventh Circuit Court of Appeals has recently employed a discovery rule under which the statute of limitations begins to run when the plaintiff knows of the violation, or “through the use of reasonable diligence should have discovered” the violation.
Welch v. Celotex Corp.,
Having decided that a discovery rule is appropriate in this action, the Court must now determine whether a genuine question' of fact exists as to whether Plaintiff actually knew or reasonably should have known that Defendant was violating the CWA more than five years prior to bringing this action. In making this determination, fhe “ ‘inferences to be drawn from the underlying facts ... must be viewed in the light most favorable to the party opposing the motion.’ ”
Matsushita Elec. Indus. Co., Ltd. v. Zenith Radio Corp.,
Defendant has produced' competent evidence showing that its agents contacted the Corps of Engineers regarding the construction of the dam. (Def.’s Reply Br. at 14). Plaintiff, however, has produced competent evidence showing that the Government was not aware of the violation until 1989. (Mazanti Aff. ¶¶3, 4, 7(e)). Accordingly, for summary judgment purposes, Defendant has not met its burden of showing that no genuine question exists as to'whether the Government actually knew of the violation more than five years before filing this action.
Alternatively, Defendant argues that the Court should find as a matter of law that Plaintiff reasonably should have known of the violation before February 14, 1986. (Def.’s Reply Br. at 15). In support of this argument, Defendant asserts that “the discovery of the facts supporting the claim by any responsible government agency or official” is sufficient to trigger the statute. .
(Id.
at 15 n. 8). Thus, Defendant argues, Plaintiff should reasonably have known of the violation due
*696
to the above-mentioned contact with the Corps of Engineers and the fact that Defendant secured a Safe Dams Act Permit from the State of Georgia and a construction permit from the city of Alpharetta.
(Id.
at 11). Moreover, Defendant asserts that Plaintiff was placed on notice of the violation due to: (1) the high degree of publicity surrounding the building of the lake, (2) aerial photographs in the Government’s possession showing the lake, and (3) the fact that evidence of the dam’s existence was shown in public records, the contents of which the Government is charged with knowing.
(Id.
at 15-16). The Court concludes, however, that, although it is possible that Defendant could ultimately prove at trial that Plaintiff should have discovered the infraction, none of the above-cited facts is sufficient for the Court to say as a matter of law at the summary judgment stage that the Government reasonably should have known of the violation at issue before February 14, 1986.
See, e.g., Welch,
2. Laches
Defendant alternatively asserts that Count I is barred by the doctrine of laches.
9
Under the law in this circuit, however, “[i]t is well settled that the United States is not ... subject to the defense of laches in enforcing its rights.”
United States v. Moore,
C. Plaintiffs Motion for Partial Summary Judgment
The Government has moved for summary judgment on Defendant’s affirmative defens
*697
es of laches, estoppel, and equal protection. As an initial matter, Defendant asserts that a motion for summary judgment is not an appropriate procedural device for striking affirmative defenses. (Def.’s Resp. to Govt.’s Mot. for Summ.J. at 2). Although this argument does not appear to the Court to be persuasive,
see generally
10A Charles A. Wright
&
Arthur R. Miller, Federal Practice and Procedure § 2734, at 406-07 (1983) (defenses that raise no material issues of fact may be subject to partial summary adjudication in plaintiffs favor in accordance with Rule 56), the Court will deny Plaintiffs motion for partial summary judgment and instead strike any insufficient defenses on its own initiative pursuant to Rule 12(f).
See, e.g., FDIC v. British-American Corp.,
For the reasons discussed
supra,
the Court finds that Defendant’s laches defense is insufficient as a matter of law and, accordingly, the Court directs that this defense be stricken. Additionally, under the law in this circuit, absent “affirmative misconduct” on the part of a government agent, the Government cannot be estopped when it is exercising its sovereign powers for the benefit of the public.
Deltona Corp. v. Alexander,
CONCLUSION
For the foregoing reasons, Defendant’s Motion for Partial Summary Judgment [T5] is DENIED, Plaintiffs Motion for Partial Summary Judgment [27] is DENIED, and Plaintiffs Motion to Amend Complaint [33] is GRANTED. The Court directs that Defendant’s laches and estoppel defenses be stricken pursuant to Rule 12(f) of the Federal Rules of Civil Procedure.
SO ORDERED.
Notes
. The parties have entered into a Proposed Partial Consent Decree that would settle Counts II, III, and IV of the Complaint. Count V, which pertains to the construction of a recreation area below Lake Windward, is not covered by the consent decree and is not at issue in this Order.
. In Bonner v. City of Prichard, 661 F.2d 1206, 1209 (11th Cir.1981) (en banc), the Eleventh Circuit Court of Appeals adopted as binding precedent all of the decisions of the former Fifth Circuit Court of Appeals handed down prior to the close of business on September 30, 1981.
. Plaintiff, however, asserts that § 2462 does not apply to its request for injunctive relief (see infra part B(l)(b)).
. The Government cites
Holmberg v. Armbrecht,
.
But see United States v. C & R Trucking Co.,
. In addition to proscribing the discharge of dredged or fill material containing pollutants, the CWA establishes effluent limitations for the kind and quantity of pollutants industrial and municipal dischargers may release into the water. These discharges .are regulated by the EPA through NPDES permits.
.NPDES permits contain specific monitoring and reporting obligations.
. Because of its decision that a genuine question of material fact exists as to when Plaintiff knew or should have known of the violation, the Court finds it unnecessary to address Plaintiffs "continuing violation” argument.
. In order to preclude an action due to laches, a defendant must establish that: (1) the plaintiff delayed in asserting the right or claim, (2) the delay was not excusable, and (3) the delay caused the defendant undue prejudice.
Conagra, Inc. v. Singleton,
. In support of its argument that the defense of laches should be available in this action, Defendant has cited several cases in which the Government was held to be subject to the defense. The majority of these cases, however, involve the Equal Employment Opportunity Commission and, as the Fifth Circuit Court of Appeals has observed, suits by the EEOC are different for laches purposes than other governmental suits.
