…because the TCEQ sure thinks there is. Ireland said this in response to the Fort Worth League of Neighborhoods report that shows drilling toxins disperse for a couple of miles. The League recommended a one mile setback from schools.
Below is an email from the TCEQ in response to Argyle residents who woke up one day to find a permanent flare in their backyard. H2S = Hydrogen Sulfide.
Molly Wentworth asked me to answer your question. The 24 ppm limit of H2S you mentioned is the concentration in the gas stream heading for the flare. As long as the concentration is at or below 24 ppm H2S in this gas stream, [Could I interrupt here to ask: Who is measuring how much H2S is in the gas stream?] then the company qualifies for the permit by rule (PBR). When the stream is burned in the flare, then the H2S concentration is decreased substantially. In addition, the ground-level concentration of H2S would be even lower due to dilution in the air before it gets to ground level. The ground level concentration of H2S onsite (where workers would be exposed) and off-site (exposure to residents) would be below levels that would produce harmful health effects. The concentration of H2S onsite must meet the OSHA regulatory standards of 20 ppm (short-term 15-min time period) or 50 ppm (for 10 min once per 8-hr shift). The concentration of H2S offsite must meet the state standard of 0.08 ppm protective of residents.
Please let me know if you have additional questions. Thank you, Roberta Grant

It’s ridiculous for Ed Ireland to say there is no sulphur in the Barnett Shale but he will say anything–ANYTHING–and I’m sure people are catching on to that by now.
