## Abstract

EPA is announcing that it is lifting 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 completed its further evaluation of additional information that has become available since the stay was put in place regarding the human health and environmental effects of hydrogen sulfide, and the Agency published a position that the stay should be lifted in the February 26, 2010, Federal Register document "Intent to Consider Lifting Administrative Stay; Opportunity for Public Comment." Based on EPA's further evaluation and the consideration of the public comments received on the notice of intent, EPA continues to believe 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 lifting the Administrative Stay of the reporting requirements for hydrogen sulfide.
