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

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

Among the many 12 refineries that emitted above the maximum degree for benzene, 5 have been in Texas, 4 in Louisiana, and one every in Pennsylvania, Indiana and the US Virgin Islands, a new evaluation by the Environmental Integrity Venture revealed on Thursday.

Benzene is a known carcinogen that's highly poisonous and risky when exposed to air. Much of the surplus emissions come by means of leaks from valves, tanks, pumps and different means that are exhausting to detect.

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

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

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

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

“If [facilities] can’t get their benzene beneath the action stage, year after year, we really need to see enforcement from the EPA,” stated Eric Schaeffer, the chief director of the Environmental Integrity Venture, in a press conference. “You might want to begin paying penalties when your fence-line levels persist,” he added.

Lifetime exposure to benzene at ranges as little as 0.13 microgram per cubic meter might trigger a danger of up to one additional cancer case for every one million exposed, based on the EPA. The higher the level of benzene, the higher the health threat.

Marathon Petroleum’s Galveston Bay refinery in Texas City had the highest average internet benzene levels in 2021, in keeping with the analysis of the self-reported information. Roughly 37,000 folks dwell inside a three-mile radius of the refinery. Amongst them, 62% are people of shade and 47% are low-income.

“This evaluation provides vital perception into why the Houston area is an industrial most cancers hotspot,” said Leticia Gutierrez of advocacy group Air Alliance Houston, on the press convention.

“Individuals residing near these services have greater [exposure] to lifetime cancer danger than another a part of the state, yet the regulatory businesses chargeable for protecting us proceed to approve permits for these services,” Gutierrez said.

Environmental Integrity Challenge notes that its analysis didn't measure concentrations of benzene inside neighborhoods adjacent to refineries, and does not replicate the actual ranges of benzene within the communities.

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