Opinion

UNITED STATES DISTRICT COURT MIDDLE DISTRICT OF LOUISIANA

ATCHAFALAYA BASINKEEPER, INC., CIVIL ACTION ET AL. VERSUS SCOTT A. SPELLMON, ET AL. NO. 23-01697-BAJ-RLB RULING AND ORDER This case concerns an after-the-fact permit (a permit that is granted after construction has begun) issued by the U.S. Army Corps of Engineers and its officials (“Defendants” or “Corps”) for a structure (the “Miller Structure”) in Pat’s Throat Bayou. Plaintiffs Atchafalaya Basinkeeper and Louisiana Crawfish Producers Association-West are nonprofit organizations alleging that the Corps violated the Clean Water Act (“CWA”) and the Rivers and Harbors Act (“RHA”) and acted arbitrarily, capriciously, and in excess of statutory authority when it issued the permit after-the-fact as a Nationwide Permit (“NWP”) 14. Now before the Court are Plaintiffs’ Motion For Summary Judgment (Doc. 30) and the Federal Government Defendants’ Cross Motion For Summary Judgment (Doc. 33). The parties submitted supplemental briefing. (Docs. 35, 36). Plaintiffs seek relief in the form of a Court Order: (1) Declaring the Corps’ authorization of the Miller Structure to be illegal; (2) Vacating/setting aside the Corps’ NWP authorization #MVN-2021-01131- CF for the Miller Structure;

(8) Enjoining the application of NWP 14 or any other Army Corps Nationwide Permit to the structure; (4) Declaring that the Corps’ regulations allowing it to issue nationwide permits under the RHA exceeds the Corps’ statutory authority, and vacating that regulation; (5) Declaring that use of NWP 14 for after-the-fact authorizations is illegal under the RHA, and enjoining such uses in the Atchafalaya Basin. The Court has carefully considered the Administrative Record, the arguments of all parties, and the applicable law and jurisprudence in this matter. For the following reasons, Plaintiffs’ and Defendants’ Motions will both be GRANTED IN PART and DENIED IN PART. I. FACTUAL BACKGROUND Pat’s Throat Bayou is located within the Atchafalaya Basin. (AR 10-12). Pat’s Throat has long been used for access to fishing grounds (AR 87; AR 93), and it sustains the area’s crawfish populations. (See AR 87-88, AR 93). Pat’s Throat Bayou is also a historically navigable waterway falling under the Corps’ jurisdiction. (See AR 90). In September 2021, the Miller Hunting Club built a structure! (the “Miller Structure”) across Pat’s Throat to access additional hunting areas without first obtaining a permit from the Corps. (AR 84; AR 98; AR 90). The Miller Structure is approximately 32 feet long, 17 feet wide, and 6 feet tall, and has a few culverts so

that flowing water can pass through it (AR 1; AR 18; AR 84; AR 75-78, AR 56-57). The Miller Structure spans across Pat’s Throat Bayou, so boats cannot pass it. (See AR 75-78, AR 56-57, AR 138, Doc. 30-3 § 20 Doc. 30-7 § 12). Prior to the construction of the Miller Structure, fishermen would regularly clear away branches and trees that fell into Pat’s Throat if the debris blocked boat access. (Doc. 30-3 4 12). In October 2021, Plaintiff Atchafalaya Basinkeeper sent the Corps a letter notifying it of the “illegal dam ... across Pat’s Throat ... [which] completely stops all navigation through the bayou.” (AR 93). The letter warned that the structure would reduce the water flow speed and “forever alter the hydrology of the area if allowed to remain into the high-water season.” (AR 98—94). Plaintiff also attached photographs of the structure. (Id.). Later that month, the Corps issued Benjamin Miller (“Miller”) of the Miller Hunting Club a “Notice of Violation” for the “unauthorized work and fill material in section 10 waters” that created the structure. (AR 90). The Corps noted that the activity was a violation of both the RHA and the CWA. (/d.). Plaintiffs were not informed whether the Corps pursued any follow-up enforcement action, so Plaintiffs sent a Notice of Intent to File a Clean Water Act Suit Against Miller Hunting Club to Benjamin Miller in November 2021, copying the Corps on this notice. (AR 86~—89). The November 2021 Notice alleged that Miller discharged fill into jurisdictional waters without a permit, in violation of the Clean Water Act. (AR 86-88). The notice also noted that although fishermen had used Pat’s Throat for navigation for over a century, “navigation [was] now completely impounded” because of the structure. (Id.).

Miller proceeded to submit an after-the-fact permit application to the Corps in January 2022. (AR 83-85). The Corps also received several photographs that Miller took of the Miller Structure. (AR 14-17). The Miller Structure required at least two types of legal permission from the Corps: (1) authorization under Section 404 of the Clean Water Act to discharge fill as a pollutant into navigable waters (88 U.S.C. §§ 1811(a); 1844; 1362(7); and (2) authorization under Section 10 of the Rivers and Harbors Act to obstruct navigable waters (83 U.S.C. § 408). The Corps asked Miller whether others used the Pat’s Throat for access, and Miller said “Pat[’]s [T]hroat is cluttered with debris and fallen trees. So any boat travels could not happen,” also sending a picture of debris and fallen trees in Pat’s Throat (AR 51-55). This conflicted with Plaintiffs’ communications with the Corps, which stated that fishermen were navigating through Pat’s Throat. (AR 87; AR 93). Without conducting a site visit, in March 2022, the Corps granted the Miller Structure an after-the-fact permit under NWP 14 (AR 7-8), along with a Memorandum for Record (AR 1-6), that authorized the Miller Structure under Section 10 of the RHA and Section 404(b) of the CWA. A month after the Corps authorized the Miller Structure, Corps employees sent emails to one another indicating that they did not know the bottom elevation of water at the Miller Structure, nor did they have information about the navigability of Pat’s Throat besides the photograph of the debris Miller sent. One email said: During low-water, how deep is the water in Pat’s Throat at the culverts? And, do we know what the bottom elevation (NGVD) is at the culvert location? □□□

curious to know at what gauge elevation does the water begin to backflow from Whiskey Pilot Channel into Pat’s Throat and compare the elevations. This should shed some light on navigability, if Pat’s Throat is not littered with obstructions (i.e., falling trees, logs, etc.). Also, go ahead and schedule a site visit soon so we can confirm the presence of the water control structure (WCS) and photographically document the navigability of Pat’s Throat from the WCS to the culverts, basically is it passable by boat. (Doc. 21-2 at 2 (emphasis added)). Another Corps employee responded to the email as follows: When its low I think the water is a foot or two feet max based on the ATF drawings. Attached is a photo the Hunting Club provided me showing that debris is in the canal. The photo was provided when the Atchafalaya River was moving towards flood stage so it doesn’t quite represent the lowest water level. The Hunting Club said that this debris is minor compared to larger debris areas in the canal so currently I believe that the waterway is currently impassable unless all of the debris would be removed. If all the debris would be removed then it MAYBE would be navigable during high waters for a few months a year. We don’t know the bottom elevation (NGVD) at the culvert location. (emphasis added) (/d. at 1). The record does not reflect that the Corps visited the Miller Structure before or after authorizing the Permit. Plaintiffs brought this instant lawsuit in December 2028, alleging that the Miller Structure did not meet the General or Regional Conditions required for it to obtain an after-the-fact NWP 14. Plaintiffs also allege that the Corps’ regulations authorizing it to issue after-the-fact permits and nationwide permits were unlawful. II.
