Orange County Coastkeeper Urges the U.S. Army Corps of Engineers to Fix Environmentally Harmful Newport CAD Project

Posted on March 2, 2023

The proposed Newport CAD facility would jeopardize marine life and put Newport Bay at risk of contamination due to an insufficiently thin layer of sediment atop toxic chemicals.

NEWPORT BEACH— Orange County Coastkeeper has demanded the U.S. Army Corps of Engineers and the City of Newport Beach take further action to protect Newport Bay and its biota from the disposal of dredged, contaminated sediment in the City’s proposed Confined Aquatic Disposal (CAD) facility.

The City of Newport Beach proposed the CAD facility to address underwater sediment buildup in the harbor’s main channel. However, samples of the polluted sediment showed exceedances too high in mercury and polychlorinated biphenyls (PCBs) to qualify for disposal in the EPA-approved offshore dump site known as LA-3.

In partnership with the U.S. Army Corps of Engineers, the City plans to dredge areas of Newport Bay and bury the removed sediment in a hole under the harbor’s turning basin. Because the dredged material is highly polluted with toxic chemicals, the City will eventually cover the hole with layers of less contaminated sediment to act as a partial barrier.

On January 5, 2023, Coastkeeper sent the Army Corps a 60-day notice of intent to file a lawsuit for failing to consider the project’s potential impacts on federally threatened species. Under the Endangered Species Act, the Army Corps was obligated to consult with the National Marine Fisheries Service about the project’s effects on specific species, including green sea turtles.

Though still recovering from historic overharvesting, green sea turtles are present in many Southern California waterways, particularly those rich in seagrass like Newport Bay. Green sea turtles have been sighted in Newport Bay more recently, and the National Oceanic and Atmospheric Administration expect Southern California to see green sea turtles more frequently soon.

Coastkeeper first expressed its Endangered Species Act concerns to the Army Corps in early 2022 through the National Environmental Policy Act public comment process. The letter also addressed the Army Corps’ failure to consider, among other things, adequately:

  1. Project alternatives such as remediation.
  2. A thicker interim cap layer to better protect against the escape of toxic pollutants.
  3. Impacts on marine mammals, including dolphin species known to enter Newport Bay.

According to the Coastkeepers, the Army Corps did not consider these comments before drafting its final Environmental Assessment and Finding No Significant Impact on the project.

Coastkeeper hopes the Army Corps and City will correct the project’s inadequacies for the health of Newport Bay; however, Coastkeeper is prepared to take legal action if not.
