The most obvious example is Pinedale, where federal ambient air quality standards were violated, largely because of emissions from natural gas production. Regulators say the air elsewhere in the state is fine. But some worry that Wyoming doesn’t have a sufficient monitoring network to know for sure.

But though there may be a lot of wells, they’re considered small facilities, so their cumulative effects are never counted up and regulations are more lax than for large emitters. Wyoming Public Radio’s Irina Zhorov reports that that could be a problem since in aggregate, their pollution can be significant.&nbsp;&nbsp;</p> Sat, 18 Jan 2014 00:15:52 +0000 Irina Zhorov 52773 at http://wyomingpublicmedia.org Small Emission Sources Could Mean Big Pollution, But No One’s Counting Railroads attempt to reduce coal dust emissions http://wyomingpublicmedia.org/post/railroads-attempt-reduce-coal-dust-emissions <p></p> Wed, 01 Jan 2014 01:28:11 +0000 Stephanie Joyce 52036 at http://wyomingpublicmedia.org Railroads attempt to reduce coal dust emissions Emissions measurements advance case for natural gas http://wyomingpublicmedia.org/post/emissions-measurements-advance-case-natural-gas <p>Natural gas’ reputation as a climate-friendly alternative to coal has been tarnished recently by concerns that methane—a potent greenhouse gas—is leaking in copious quantities as the fuel makes its way from the ground to the consumer. <a href="http://www.pnas.org/content/early/2013/09/10/1304880110.abstract">A study</a> released Monday provides the first on-the-ground measurements of methane leaks at&nbsp;hydraulically fractured natural gas well sites, and they're not as bad as some had feared.</p><p></p> Tue, 17 Sep 2013 00:50:57 +0000 Stephanie Joyce 47013 at http://wyomingpublicmedia.org Emissions measurements advance case for natural gas Coal industry braces for new emissions rules http://wyomingpublicmedia.org/post/coal-industry-braces-new-emissions-rules <p>The federal government is getting ready to unveil rules for carbon emissions at new <span class="highlight" id="0.4811786012353736" name="searchHitInReadingPane">coal</span>-fired power plants, and they probably won't be what industry had hoped for.</p><p></p> Mon, 16 Sep 2013 13:25:19 +0000 Stephanie Joyce 46972 at http://wyomingpublicmedia.org Coal industry braces for new emissions rules DEQ engine emissions study shows significant non-compliance http://wyomingpublicmedia.org/post/deq-engine-emissions-study-shows-significant-non-compliance <p>The Wyoming Department of Environmental Quality is wrapping up an engine emissions study it started in May of 2011.
