Maine Pulp Mill Faces $794,456 in OSHA Fines After Two Worker Deaths

What OSHA Found at Woodland Pulp

Woodland Pulp, a hardwood pulp mill in Baileyville, Maine, is facing $794,456 in proposed federal workplace safety fines after OSHA investigations tied two separate incidents to serious chemical safety failures. The agency issued four willful and eight serious citations covering a hydrogen sulfide release that killed two workers in January and a hydrogen peroxide fire in March.

According to OSHA, the January deaths occurred during a cold-weather shutdown when workers were exposed to high concentrations of hydrogen sulfide. The mill lacked adequate gas alarms and breathing equipment. The Chemical Safety and Hazard Investigation Board, which is running its own probe, said sulfuric acid mixed with sulfur-containing process fluids in the bleach plant sewer system and produced the toxic gas. The board also said the two workers who died had no personal hydrogen sulfide monitors, no fixed detectors were installed in the building, and 10 other workers were exposed.

The March fire began after roughly 4,400 gallons of 50% hydrogen peroxide was released and mixed with wood pulp that had accumulated on the ground. OSHA separately cited Woodland Pulp for failing to train workers on hydrogen peroxide hazards, skipping required respirator evaluations and fit tests, leaving chlorine and acid lines unlabeled, and failing to control hydrogen sulfide exposure risks.

Woodland Pulp has 15 business days to comply with the citations, request an informal conference with OSHA, or contest the findings before the Occupational Safety and Health Review Commission. The company has been inspected 13 times since 2017, including after a chemical exposure in the same part of the mill that sent 14 employees to hospitals.

Why This Safety Record Matters Beyond the Fine

Repeated Inspections Raise Questions About Corrective Action

OSHA records cited in the case show Woodland Pulp has been inspected 13 times since 2017, including a previous chemical exposure in the same area of the mill that hospitalized 14 employees. That history is a fact; the interpretation is that the current citations do not look like isolated lapses. Four willful citations, in particular, signal OSHA's view that the violations went beyond ordinary negligence, and a prior mass-exposure event in the same building makes it harder to argue the hazards were unknown.

The Missing Safety Controls at the Center of the Case

The incidents share a common theme: workers lacked the basic detection and protection systems that are standard in chemical process environments. Hydrogen sulfide is a fast-acting toxic gas that can overwhelm workers quickly, especially during shutdowns when process chemistry shifts. Without fixed detectors and personal monitors, as the CSB described, workers had little warning. The peroxide release adds a second failure: 4,400 gallons of a strong oxidizer escaping and mixing with fuel in the form of accumulated wood pulp is precisely the kind of containment and housekeeping failure that process-safety programs are designed to prevent.

What the CSB Investigation Could Mean

The Chemical Safety and Hazard Investigation Board rarely issues fines, but its findings can carry weight beyond a single company. Its conclusion that bleach plant sewer chemistry generated the hydrogen sulfide could lead to industry-level guidance on monitoring sewer systems and managing shutdown procedures. That remains an open question — the board's investigation is ongoing and no final recommendations have been published.

Costs Beyond the $794,456 Penalty

The proposed fine is only the direct financial hit. If Woodland Pulp contests the citations, it faces legal costs and a longer period of regulatory uncertainty. If it complies, it must invest in gas detection, respirator programs, training and process containment. There is also a workforce dimension: two workers died and ten others were exposed, and the company's own inspection history means employees and the local community will be watching how the mill responds.

Next Steps for Woodland Pulp and the Pulp Industry

For Woodland Pulp and other pulp and paper operators:

• Woodland Pulp has 15 business days from the citations to comply, request an informal conference with OSHA, or contest before the Occupational Safety and Health Review Commission; a documented decision is the immediate task.
• Re-audit hydrogen sulfide protection in bleach plant and sewer areas: the CSB found no fixed detectors and no personal monitors for the workers who died, and 10 other employees were also exposed.
• Review peroxide handling around any accumulated fibrous material: the March fire followed the release of about 4,400 gallons of 50% hydrogen peroxide that mixed with wood pulp on the ground, so containment, drainage and housekeeping procedures need to be verified.
• Close the cited training gaps — hydrogen peroxide hazard training, respirator evaluations and fit tests — and make sure chlorine and acid lines are labeled before restarting affected operations.
• Other mills should treat Woodland Pulp's 13 inspections since 2017 and the earlier mass exposure in the same area as a reminder that repeat findings in one process area point to systemic problems, not isolated mistakes.
