Nonprofit sign-on letter to EPA administrator Lisa Jackson
Dear Administrator Jackson:
The community, environmental, and public health organizations named below request that you formally list Hydrogen Sulfide (H2S) as a hazardous air pollutant (HAP), as defined in Title III, section 112(b) of the 1990 Clean Air Act Amendments (CAA). We assert that EPA must act to address adverse H2S impacts based on evidence of harmful exposures in numerous communities and its toxicological effects at low concentrations such as non-cancer effects and emerging evidence that H2S is a genotoxic agent, meaning it damages DNA. EPA has assessed the need to list H2S as a HAP, but no formal listing action has been taken. H2S is clearly an unlisted hazardous air pollutant.
