The Environmental Protection Agency published in the Federal Register of October 17, 2011, a document lifting the Administrative Stay of the reporting requirements for hydrogen sulfide. The Office of the Federal Register mistakenly lifted the stay of the reporting requirements for methyl mercaptan, and the document also inadvertently left out language in the preamble and contained incorrect language in the amendatory instruction section, which section is required by 1 CFR 21.1. This document affirms that the stay on the reporting requirements for methyl mercaptan was not lifted and sets out the language in the preamble and the amendatory instruction section as it should have printed.
They share the same problem. Their properties border a proposed injection well that could pump hundreds of thousands of gallons a day of oilfield waste into the ground. This waste, known in the industry as "production water," is mostly oily saltwater used in drilling. But it also contains substances such as waste crude, sludge from storage pits and tank bottoms, used glycol, amine, and hydrogen sulfide scrubber liquid, to name only a few. There are at least 26 acknowledged chemicals in the waste, including such known carcinogens as benzene and one category unhelpfully listed as "other." It's not the kind of stuff [Cecile Carson] wants in the drinking water she brings up from her well. Yet the Railroad Commission doesn't classify oil and gas waste as hazardous. That means the commission,...
A toxic gas found in Versailles could be harmful at lower levels than originally thought, according to studies the U.S. Environmental Protection Agency is examining. Hydrogen sulfide, a common gas that smells like rotten eggs and is associated with such things as petroleum production and decaying plants, long has been known to be deadly in high concentrations. However, growing scientific evidence shows that prolonged exposure at low levels might affect memory and coordination, and cause lung and eye problems.
Whenever natural gas and other gas sources become infused with hydrogen sulfide, the result is what industry experts term "sour" gas. To make the gas usable, oil and gas companies must remove that hydrogen sulfide, which is both poisonous and corrosive. Removal is done through a filtering medium, and it's a costly, messy and time-consuming process.
