EPA is issuing this final rule to stay the requirement for certain affected sources to comply with the title V permit program during the pendency of the reconsideration process. On June 15, 2010, EPA notified Petitioners that the Agency intended to initiate the reconsideration process in response to their request for reconsideration of certain provisions in the National Emission Standards for Hazardous Air Pollutants for Chemical Manufacturing Area Sources. Among the provisions EPA is reconsidering is a requirement that certain affected sources obtain a permit. On December 14, 2010, EPA issued a 90-day stay of the requirement for certain affected sources to comply with the title V permit program. Because we believed that the reconsideration process would not be completed within 90 days, we concurrently proposed to stay the provision requiring certain sources to obtain a permit until the final reconsideration rule is published in the Federal Register. After considering the comments received, EPA is promulgating the stay of compliance through this final rule.
