MONTREAL (Scrap Monster): Federal and North Carolina regulators have proposed a $1.905 million settlement with Domtar Paper Company to address natural-resource damage associated with decades of industrial contamination at the Plymouth mill site along the lower Roanoke River.

The U.S. Department of Justice lodged the proposed consent decree on September 16 in the U.S. District Court for the Eastern District of North Carolina in United States of America and the State of North Carolina v. Domtar Paper Company, LLC.

The case was brought by federal and state natural-resource trustees under the Comprehensive Environmental Response, Compensation, and Liability Act, or CERCLA.

The settlement remains proposed and is subject to public review and court approval.

$1.75 Million Would Go Directly to Restoration

Under the proposed agreement, Domtar would pay a total of $1.905 million.

Of that amount, $1.75 million would be deposited into the federal Damage Assessment and Restoration Revolving Fund administered through the National Oceanic and Atmospheric Administration.

The money would support restoration of natural resources injured near the Plymouth mill site, including future floodplain, wetland and fish-passage projects.

An additional $155,000 would be paid to the U.S. Department of the Interior's Natural Resource Damage Assessment and Restoration Fund to cover trustee planning, oversight and monitoring costs.

760 Acres of Forested Wetlands Would Be Protected

A major component of the proposed agreement is permanent protection of approximately 760 acres of Warren Neck forested wetlands adjoining the Roanoke River.

Domtar would record a conservation agreement restricting future development on the property.

The tract contains bottomland forest and wetlands that provide fish nursery habitat and support water quality in the lower Roanoke watershed.

Federal and state trustees identified conservation of Warren Neck as one of their preferred restoration measures because of its ecological importance and the development pressure facing floodplain habitat.

Floodplain Project Would Improve More Than 600 Acres

A separate restoration project would target degraded road crossings in the lower Roanoke River floodplain.

The plan calls for repairing or replacing up to five impaired crossings and culverts that restrict water movement and fish access.

The work is expected to reconnect approximately three miles of historic stream channels to more natural flow and flood conditions.

Trustees estimate the project would improve more than 600 acres of floodplain habitat.

Fish-friendly culverts and restored connections would allow aquatic species to move more freely between the river, floodplain channels and wetland nursery areas.

Mill Site Has Operated Since 1937

The Plymouth site began operating as a wood and paper-products manufacturing facility in 1937.

Weyerhaeuser operated the facility from 1957 until 2007, when Domtar acquired the operation and assumed site-related environmental cleanup obligations.

The roughly 2,400-acre property sits near the confluence of Welch Creek and the Roanoke River.

Federal environmental records state that industrial operations over several decades resulted in releases of hazardous substances into soil, groundwater, Welch Creek and the Roanoke River.

Contaminants associated with the site have included dioxins, furans and mercury.

Fish Consumption Advisories Date Back Decades

Contamination in the lower Roanoke watershed has resulted in long-running fish consumption restrictions.

North Carolina first imposed fish consumption advisories affecting Welch Creek and the lower Roanoke River in 1990. The affected area was expanded to the western Albemarle Sound the following year.

Additional advisories addressing elevated mercury levels were issued in later years.

Current dioxin guidance for portions of the lower Roanoke River continues to advise women of childbearing age and children not to eat catfish or carp from the affected waters, while other consumers are advised to limit those fish to no more than one meal per month.

The restrictions illustrate how environmental injuries at the site affected not only aquatic habitat but also recreational use of the river.

Cooling-Water Withdrawals Also Injured Fish

The trustees' case extends beyond chemical contamination.

The mill historically withdrew large volumes of water from the Roanoke River for industrial cooling.

Those withdrawals entrained larval fish into the cooling-water system, contributing to mortality among species including striped bass, river herring and white perch.

Inside Climate News, citing state and federal records, reported that the withdrawals were estimated to reduce those fish populations by roughly 100,000 fish per day.

Domtar later installed high-capacity cooling towers that eliminated direct cooling-water withdrawals from the river.

The proposed settlement gives the company restoration credit for those improvements because they reduced fish mortality.

Earlier Domtar Projects Receive Restoration Credit

The restoration package also recognizes several projects Domtar completed before the proposed settlement.

Those measures include:

• high-capacity cooling-water towers that reduced or eliminated river withdrawals used for cooling;
• lighting modifications at the Plymouth facility;
• seasonal operating measures designed to protect spawning fish; and
• improvements to the Plymouth Waterfront Park and boat-access area.

The new Phase 2 restoration plan builds on an earlier restoration program adopted in 2006.

Settlement Resolves Natural-Resource-Damage Claims

The case is being pursued through the federal Natural Resource Damage Assessment and Restoration process.

Under CERCLA, government trustees may seek compensation when hazardous-substance releases injure publicly owned natural resources or reduce services those resources provide, including fishing and recreation.

The trustees in the Plymouth case are NOAA, the U.S. Fish and Wildlife Service and the North Carolina Department of Environmental Quality.

The proposed consent decree would resolve Domtar's alleged natural-resource-damage liability for injuries known as of the date the decree was lodged.

It is separate from earlier Superfund cleanup work aimed at containing or removing contaminated soil and sediment at the site.

Site Has Already Undergone Extensive Cleanup Work

The Plymouth property has been the subject of federal environmental remediation for decades.

The Environmental Protection Agency considers the property a Superfund-caliber site being addressed through the Superfund Alternative Approach.

Previous cleanup work has included excavation of contaminated material and placement of a thin sand cap over contaminated sediment in portions of Welch Creek.

Domtar assumed the remaining site-related environmental obligations when it acquired the facility in 2007.

The new settlement is focused specifically on compensating the public for natural-resource injuries rather than replacing those cleanup obligations.

Lower Roanoke Has Significant Ecological Value

The lower Roanoke River supports one of the largest remaining systems of bottomland hardwood forest on the Atlantic Coast.

Its floodplain provides habitat for migratory fish, waterfowl and other wildlife and serves as an important nursery system connecting the river with Albemarle Sound.

Species using the watershed include striped bass, river herring, American shad and federally protected Atlantic sturgeon.

That ecological importance is one reason the restoration plan places substantial emphasis on wetland conservation, fish passage and floodplain reconnection.

Public Comment Remains Open

The proposed consent decree and draft restoration plan are currently undergoing public review.

Current Department of Justice and NOAA materials list the public-comment period through October 26, 2026.

After the comment period closes, regulators will review submissions before deciding whether revisions are needed and whether to proceed with final approval of the settlement and restoration plan.

Market and Industry Read

The case is a reminder that environmental liabilities associated with pulp and paper operations can remain active decades after the original releases occurred and can transfer with ownership of industrial properties.

For forest-products companies, the financial exposure can extend beyond conventional cleanup costs to include restoration of fisheries, wetlands, recreational resources and other public natural assets.

In this case, the proposed resolution combines direct payments, long-term land protection and credit for previously completed environmental improvements rather than relying on a single cash penalty.

If approved, the settlement would move the lower Roanoke River case from damage assessment toward a new phase focused more heavily on habitat restoration and long-term ecological recovery.
