The requirements within the ACO will return Emerald to compliance with the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Miscellaneous Organic Chemical Manufacturing at 40 C.F.R. Part 63, Subpart FFFF. EPA issued Emerald a Finding of Violation (FOV) on January 21, 2010 for leak detection and repair (LDAR) violations. The FOV alleged that Emerald failed to comply with 40 C.F.R. ? 63.1033(b)(1) which states, ?Each open-ended valve or line shall be equipped with a cap, blind flange, plug, or a second valve?? Identification of the violation was made during a comparative monitoring inspection at the Emerald facility from July 28-29, 2009. Thirteen separate uncapped lines were identified. The ACO will ensure all violations identified in the FOV are corrected, as well as required Emerald to conduct a third-party audit of the facility?s leak, detection, and repair program.
