Texas Refineries And Chemical Plants Releasing Tens Of Thousands Of Tons Of Pollution

A damning new report from the Environmental Integrity Project (EIP) reveals some startling information regarding pollution in the state of Texas. According to the report, oil refineries and chemical plants in the state are releasing tens of thousands of tons of pollution every year, without as much as a peep from state regulators or the Environmental Protection Agency (EPA.)

Most of these emissions are the result of industrial accidents and other “equipment malfunctions” taking place at processing plants across the state. Among the more dangerous chemicals being released into the atmosphere and surrounding environment are sulfur dioxide and nitrogen oxide, both of which are major contributors to ozone depletion.

A few highlights from the new report:

Every year, refineries, chemical plants, and natural gas facilities release thousands of tons of air pollution when production units break down, or are shut off, restarted or repaired. Most of these “emission events” release pollution through flares, leaking pipelines, tanks, or other production equipment. Information obtained from the Texas Commission on Environmental Quality (TCEQ) for the last three years shows just how significant that pollution can be.

Between 2009 and 2011, emission events at chemical plants, refineries, and natural gas operations released a combined total of more than 42,000 tons of sulfur dioxide and just over 50,000 tons of smog- forming Volatile Organic Compounds (VOCs), according to industry reports filed with TCEQ. See Table 1. These releases are in addition to the amounts released year-round during so-called “normal operations,” and are usually not included in the data the government uses to establish and enforce regulations, or to estimate their health impacts. Natural gas operations — which include, well heads, pipelines, compressors, boosters, and storage systems — accounted for more than 85% of total sulfur dioxide and nearly 80% of the VOCs released during these episodes. Both pollutants are linked to asthma attacks and other respiratory ailments, and can form fine particles that contribute to premature death from heart disease.

Upsets or sudden shutdowns can release large plumes of sulfur dioxide or toxic chemicals in just a few hours, exposing downwind communities to peak levels of pollution that are much more likely to trigger asthma attacks and other respiratory systems. The working class and minority populations typical of neighborhoods near refineries and chemical plants bear the brunt of this pollution.
