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

A dozen US oil refineries final 12 months exceeded the federal restrict on average benzene emissions.

Among the 12 refineries that emitted above the utmost degree for benzene, five were in Texas, four in Louisiana, and one every in Pennsylvania, Indiana and the US Virgin Islands, a brand new analysis by the Environmental Integrity Undertaking revealed on Thursday.

Benzene is a identified carcinogen that is highly poisonous and unstable when exposed to air. Much of the excess emissions come through leaks from valves, tanks, pumps and different means which are exhausting to detect.

The Environmental Protection Company estimates 6.1 million folks within the US live inside three miles of a refinery, with low-income folks and other people of color represented at rates nearly twice that of the general inhabitants.

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

Almost half of those refineries released benzene ranges above 3 micrograms per cubic meter, which the Environmental Integrity Project defines as a long-term potential well being risk.

The EPA requires amenities 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 under the motion stage, year after year, we really must see enforcement from the EPA,” stated Eric Schaeffer, the executive director of the Environmental Integrity Challenge, in a press convention. “You need to start paying penalties when your fence-line levels persist,” he added.

Lifetime exposure to benzene at ranges as low as 0.13 microgram per cubic meter could cause a threat of up to one extra cancer case for each one million uncovered, in keeping with the EPA. The higher the extent of benzene, the higher the health danger.

Marathon Petroleum’s Galveston Bay refinery in Texas City had the very best average net benzene ranges in 2021, in keeping with the analysis of the self-reported information. Roughly 37,000 people live inside a three-mile radius of the refinery. Among them, 62% are folks of colour and 47% are low-income.

“This evaluation gives important insight into why the Houston area is an industrial most cancers hotspot,” stated Leticia Gutierrez of advocacy group Air Alliance Houston, on the press convention.

“Individuals residing near these facilities have greater [exposure] to lifetime most cancers threat than any other a part of the state, yet the regulatory businesses responsible for protecting us continue to approve permits for these facilities,” Gutierrez mentioned.

Environmental Integrity Challenge notes that its analysis didn't measure concentrations of benzene inside neighborhoods adjoining to refineries, and doesn't mirror the precise levels of benzene throughout the communities.

Marathon Petroleum and the EPA did not instantly reply to a request for remark.
