Puerto Rico Man Pleads Guilty to Wetlands Filling in Protected Bay

A man from Puerto Rico pleaded guilty on April 30, 2026, to violating the Clean Water Act through construction and filling on a property in the las Mareas area of Salinas, per the U.S. Department of Justice press release. The activities occurred within the boundaries of the Jobos Bay National Estuarine Research Reserve, a federally protected site in San Juan's jurisdiction.

The violation impacts the Jobos Bay National Estuarine Research Reserve, which spans over 2,800 acres of mangroves, wetlands, and coastal habitats in southern Puerto Rico, as documented in federal environmental records. This reserve supports biodiversity for species including manatees, sea turtles, and migratory birds, and serves research and educational programs for local communities and scientists.

The unauthorized filling affects water quality and habitat integrity for these populations, with potential ripple effects on the 18,000 residents in nearby Salinas who rely on the bay for fishing and recreation, based on U.S. Census data and reserve management plans.

Before the plea, the man faced charges for the unpermitted activities, which involved dredging and filling wetlands without required approvals from the U.S. Army Corps of Engineers. The new state establishes guilt under 33 U.S.C. § 1319, the enforcement section of the Clean Water Act, shifting the case to sentencing.

The change takes effect immediately, with a sentencing hearing scheduled in the U.S. District Court for the District of Puerto Rico, though no specific date is provided in the release.

The guilty plea triggers mandatory penalties, including potential fines up to $50,000 per day of violation and up to three years in prison, per Clean Water Act statutes. It also initiates restoration requirements, where the court may order the defendant to remove fill materials and restore the site, activating oversight by the Environmental Protection Agency.

Federal prosecutors must now prepare sentencing recommendations, while the reserve's management, under the National Oceanic and Atmospheric Administration, gains authority to enforce compliance monitoring in the affected area.

The plea follows a pattern of Clean Water Act enforcement in Puerto Rico, with the U.S. Attorney's Office for the District of Puerto Rico handling at least five similar wetland violation cases since 2020, per Department of Justice records. The Jobos Bay reserve was designated in 1981 under the Coastal Zone Management Act, establishing its protections that this case upholds.
