SUMMIT COUNTY — Taking a small step in the long-running battle over oil and gas drilling impacts to communities, the EPA this week ruled that energy companies must once again include releases of hydrogen sulfide as part of their required environmental disclosures.

Starting next year, hydrogen sulfide emissions must again be reported to the Toxics Release Inventory, a federal database that allows Americans to find out what hazardous chemicals are being released in their communities. Nationwide, communities have used the TRI to learn about chemical releases in their neighborhoods and to campaign for tighter regulations and health protections.

Hydrogen sulfide occurs naturally, but is also a byproduct of many industrial processes, including paper manufacturing, sewage treatment, or livestock feedlots. It is also found in oil and natural gas, which is considered “sour” if it has a high percentage of the compound. It may leak from drill rigs and refineries, but is often also deliberately burned off, exposing nearby communities to its harmful effects.
