Hydrogen Sulfide; Community Right-to-Know Toxic Chemical Release
Reporting
AGENCY: Environmental Protection Agency (EPA).
ACTION: Intent to consider lifting administrative stay; opportunity for public comment.
-----------------------------------------------------------------------
SUMMARY: EPA is announcing that it is considering whether to lift the Administrative Stay of the Emergency Planning and Community Right-to-Know Act (EPCRA) section 313 toxic chemical release reporting requirements for hydrogen sulfide (Chemical Abstracts Service Number (CAS No.) 7783-06-4). Hydrogen sulfide was added to the EPCRA section 313 list of toxic chemicals in a final rule published in the Federal Register on December 1, 1993. However, on August 22, 1994, EPA issued an Administrative Stay of the reporting requirements for hydrogen sulfide in order to evaluate issues brought to the Agency's attention after promulgation of the final rule concerning the human health effect basis for the listing and the Agency's use of exposure analysis in EPCRA section 313 listing decisions. Although the final rule listing hydrogen sulfide under section 313 of EPCRA remained in force, the stay deferred the reporting requirements for hydrogen sulfide while EPA completed this further evaluation. EPA has now completed its further evaluation, including a consideration of additional information that has become available since the stay was put in place regarding the human health and environmental effects of hydrogen sulfide. Based on
this further evaluation, EPA believes that the Administrative Stay should be lifted. By this current action, EPA is not revisiting the original listing decision, which was accomplished by final rule on December 1, 1993. Rather, EPA is merely presenting its rationale for
why the Administrative Stay of the reporting requirements for hydrogen sulfide should be lifted. After consideration of comments received, the Agency will issue another Federal Register document responding to comments and taking appropriate action.
Comments due by: April 27, 2010.
