Subject
Formal request: investigate potential Clean Water Act §301 fill discharge
Prepared for United States Army Corps of Engineers; United States Environmental Protection Agency, Region 6; New Mexico Environment Department; Albuquerque Metropolitan Arroyo Flood Control Authority; City of Albuquerque
Dear United States Army Corps of Engineers; United States Environmental Protection Agency, Region 6; New Mexico Environment Department; Albuquerque Metropolitan Arroyo Flood Control Authority; City of Albuquerque, I am a resident and member of the public requesting a prompt, documented investigation and coordinated response concerning the drainage or retention area near 6440 Coors Boulevard Northwest, directly east of Sagebrush Church–Riverside Campus, Albuquerque, New Mexico 87120. POTENTIAL LEGAL ISSUE AND REQUIRED CAVEAT Discharge of fill without authorization — Clean Water Act §301 Potential violation only if the investigation establishes an addition of soil, rock, sand, sediment, or another pollutant from a point source to waters of the United States without authorization. Law: Clean Water Act §301(a), 33 U.S.C. §1311(a). The photographs show material beside or near the channel; jurisdiction and the discharge path remain unverified. FULL LEGAL CITATION AND ELEMENTS TO REVIEW Review Clean Water Act §301(a), 33 U.S.C. §1311(a): except as authorized by the Act, the discharge of any pollutant by any person is unlawful. The investigation should determine whether soil, rock, sediment, trash, or other material was a pollutant; whether equipment or another discernible conveyance was a point source; whether the receiving area is a water of the United States; and whether a valid permit or other authorization covered the discharge. OFFICIAL CONTROLLING SOURCES 1. 33 U.S.C. §1311 — complete statutory text https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title33-section1311&num=0&edition=prelim ISSUE-SPECIFIC EVIDENCE STATUS CURRENT FACTUAL BASELINE (reviewed August 29, 2026) Albuquerque Metropolitan Arroyo Flood Control Authority identifies the site as the Albuquerque Metropolitan Arroyo Flood Control Authority-owned La Orilla Outlet Water Quality Structure. Albuquerque Metropolitan Arroyo Flood Control Authority authorized the on-site work at the La Orilla Outlet Water Quality Structure; that agency authorization does not by itself establish that every required permit or regulatory approval was satisfied. Albuquerque Metropolitan Arroyo Flood Control Authority reported that approximately 8–10 turtles, primarily red-eared sliders, and several bullfrogs had been captured or relocated as of August 26, 2026; wildlife professionals were involved, work was paused after wildlife concerns, relocation was not complete, and no dead or injured wildlife had been found at that point. The supplied photograph directly depicts one beaver, and witness material records direct observation of at least two beavers and one beaver den; Albuquerque Metropolitan Arroyo Flood Control Authority stated that it had not independently confirmed the beaver observation as of its August 26, 2026 public statement. A supplied photograph depicts an animal appearing to be a deceased beaver beside a roadway. In a public Facebook post, Brittany Walters says Jenn Wilson photographed the animal near Paseo and Coors and identifies it as the same beaver the community had been trying to save based on matching tail notches; the identity and the cause, timing, and circumstances of death have not been independently verified. Supplied text-message screenshots report more than 40 turtles identified in the account as snapping, western painted, red-eared slider, and spiny softshell turtles, plus one unidentified snake, many bullfrogs, and a possible alligator; the counts and species identifications require qualified official verification. Historical federal scientific records document Rio Grande silvery minnows at a La Orilla Middle Rio Grande study location; that historical evidence does not establish that silvery minnows were present inside the specific Albuquerque Metropolitan Arroyo Flood Control Authority La Orilla Outlet Water Quality Structure during the August 2026 operation. Albuquerque Metropolitan Arroyo Flood Control Authority stated that water was pumped downstream along the structure’s normal drainage path toward the Rio Grande and that water-quality samples were collected; laboratory results were pending at the time of its August 26, 2026 statement. Albuquerque Metropolitan Arroyo Flood Control Authority stated that permanent drainage modifications were under consideration. The reviewed public record does not establish the full permit history, precise regulatory jurisdiction, specific discharge authorization, detailed laboratory results, all relocation destinations, complete injury or mortality records, or final permanent-design effects. Fresh soil is visible near the channel, soil appears to be unloaded beside it, and floating debris is visible at the surface. Albuquerque Metropolitan Arroyo Flood Control Authority identifies the site as its La Orilla Outlet Water Quality Structure and stated that water was pumped downstream along the normal drainage path toward the Rio Grande and that water-quality samples were collected. Laboratory results were pending at the time of its statement. The precise outlet, volume, sample locations and results, sediment effects, regulatory authorization, and downstream monitoring remain under review. Proximity to the Rio Grande alone does not establish waters-of-the-United-States jurisdiction. ISSUE-SPECIFIC RECORDS AND FACTUAL QUESTIONS Determine the exact material placed, volume, dates, equipment, discharge path, receiving water, ownership, contractor, permit number, and whether the work caused or may cause a measurable addition of pollutants or a change in water quality. WHY PROMPT ACTION IS WARRANTED Further filling, pumping, dewatering, grading, vegetation removal, cleanup, or animal handling could alter site conditions, make water-quality or wildlife effects harder to detect, destroy evidence, and foreclose less damaging corrective options. The available record warrants inspection and preservation now even though jurisdiction, permit status, causation, species, injury, and the elements of any violation remain to be established. COORDINATED REQUEST BY RECIPIENT ROLE United States Army Corps of Engineers — Primary enforcement or regulator Inspect before further filling or dewatering; identify any §301/§402/§404 authorization; preserve samples and photographs; require lawful controls; and pursue removal, restoration, mitigation, or enforcement if the elements are established.

The report's accuracy, permit status, and legal significance require official verification and determination. This letter requests investigation, preservation, and role-appropriate assistance. The responsible authorities must establish each factual, jurisdictional, causation, intent, permit, and exception element. Respectfully, [Your name] [City], [State] [ZIP] [Your email]
