EPA Completes Chemical Removal at St. Croix Refinery; Ongoing Oversight Continues
The U.S. EPA has finalized the removal of ammonia, amines, and liquefied petroleum gas from the St. Croix refinery, which allows for the cessation of air monitoring for certain pollutants. However, the agency maintains oversight and has mandated additional safety measures and compliance actions for the facility.

The U.S. Environmental Protection Agency has completed the removal of ammonia, amines, and liquefied petroleum gas from the St. Croix refinery, allowing for the suspension of related air monitoring.
This initiative was part of a legal agreement established on December 5, 2022, with Port Hamilton Refining and Transportation, which has led to ongoing oversight requirements, including enhanced safety measures for LPG Units No. 1 and No. 2 outlined in a subsequent order on August 23, 2024. EPA's compliance inspections have also extended to wastewater discharge permits for Port Hamilton and Ocean Point Terminals, following serious deficiencies identified in previous inspections. The agency continues to evaluate compliance with environmental regulations as it oversees the facility's operations.
