US oil refineries spewing cancer-causing benzene into communities, report finds | Pollution

A dozen US oil refineries last year exceeded the federal restrict on common benzene emissions.

Among the many 12 refineries that emitted above the utmost stage for benzene, five have been in Texas, 4 in Louisiana, and one every in Pennsylvania, Indiana and the US Virgin Islands, a brand new evaluation by the Environmental Integrity Challenge revealed on Thursday.

Benzene is a recognized carcinogen that's highly poisonous and unstable when exposed to air. A lot of the surplus emissions come via leaks from valves, tanks, pumps and other means that are exhausting to detect.

The Environmental Protection Agency estimates 6.1 million individuals within the US dwell within three miles of a refinery, with low-income folks and people of colour represented at rates nearly twice that of the overall population.

Out of 129 operable oil refineries in 2021, 118 reported benzene concentration registered at or near the location, otherwise generally known as the fence-line.

Nearly half of these refineries launched benzene ranges above 3 micrograms per cubic meter, which the Environmental Integrity Venture defines as a long-term potential well being risk.

The EPA requires services to take motion in the event that they exceed an average 9 micrograms per cubic meter, or above “motion degree” emission of benzene.

“If [facilities] can’t get their benzene beneath the motion stage, yr after year, we actually have to see enforcement from the EPA,” stated Eric Schaeffer, the executive director of the Environmental Integrity Project, in a press conference. “That you must start paying penalties when your fence-line levels persist,” he added.

Lifetime publicity to benzene at ranges as low as 0.13 microgram per cubic meter may cause a danger of up to one additional cancer case for each one million uncovered, in line with the EPA. The upper the extent of benzene, the upper the well being risk.

Marathon Petroleum’s Galveston Bay refinery in Texas City had the best common internet benzene levels in 2021, based on the analysis of the self-reported data. Roughly 37,000 people live within a three-mile radius of the refinery. Among them, 62% are people of colour and 47% are low-income.

“This analysis provides vital insight into why the Houston space is an industrial cancer hotspot,” said Leticia Gutierrez of advocacy group Air Alliance Houston, on the press conference.

“People residing near these amenities have greater [exposure] to lifetime cancer danger than some other a part of the state, yet the regulatory agencies chargeable for defending us continue to approve permits for these services,” Gutierrez said.

Environmental Integrity Undertaking notes that its analysis didn't measure concentrations of benzene inside neighborhoods adjoining to refineries, and doesn't replicate the actual levels of benzene inside the communities.

Marathon Petroleum and the EPA didn't immediately reply to a request for comment.
