Hovensa has the capacity to refine more than 525,000 barrels of crude oil per day.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice announced today that Hovensa LLC, owner of the second largest petroleum refinery in the United States, will pay a civil penalty of more than $5.3 million and spend more than $700 million in new pollution controls to resolve Clean Air Act violations at its St. Croix, U.S. Virgin Islands refinery. HOVENSA, is a joint venture between subsidiaries of Hess Corporation and Petroleos de Venezuela, S.A. (PDVSA),
High concentrations of SO2 and NOx, two key pollutants emitted from refineries, can have adverse impacts on human health, and are significant contributors to acid rain, smog, and haze.
The negotiated settlement requires new and upgraded pollution controls, more stringent emission limits, and “aggressive monitoring, leak-detection and repair practices” to reduce emissions from refinery equipment and process units.
Hovensa is one of the 10 largest refineries in the world and has the capacity to refine more than 525,000 barrels of crude oil per day.
The consent decree, lodged in the District Court of the Virgin Islands, is subject to a 30-day public comment period and court approval.
The government’s complaint, filed concurrently with today’s settlement, alleged that the company made modifications to its refinery that increased emissions without first obtaining pre-construction permits and installing required pollution control equipment.
The Clean Air Act requires major sources of air pollution to obtain permits before making changes that would result in a significant emissions increase of any pollutant.
Once fully implemented, the pollution controls required by the settlement are estimated to reduce emissions of nitrogen oxides (NOx) by more than 5,000 tons per year and sulfur dioxide (SO2) by nearly 3,500 tons per year.
The settlement will also result in additional reductions of volatile organic compounds, particulate matter, carbon monoxide and other pollutants that affect air quality. Additional pollution-reducing projects at the refinery’s coking unit under the settlement will also reduce greenhouse gas emissions by over 6,100 tons per year.
The settlement with Hovensa is the 28th under an EPA initiative to improve compliance among petroleum refiners and to reduce significant amounts of air pollution from refineries nationwide through company-wide enforcement settlements.
The first of EPA’s settlements was reached in 2000, and with today’s settlement, 105 refineries operating in 32 states and territories – more than 90% of the total refining capacity in the United States – are under judicially enforceable agreements to significantly reduce emissions of pollutants.
As a result of the settlement agreements, refiners have agreed to invest about $6 billion in new pollution controls designed to reduce emissions of sulfur dioxide, nitrogen dioxide and other pollutants by more than 360,000 tons per year, according to EPA.
