Federal Standards for Marine Tank Vessel Loading Operations and National Emission Standards for Hazardous Air Pollutants for Marine Tank Vessel Loading Operations

This action promulgates standards under section 183(f) of the Clean Air Act (the Act) and requires reasonably available control technology (RACT) to limit air emissions of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from new and existing marine tank vessel loading operations. VOC emissions, together with nitrogen oxides are precursors to the formation of tropospheric ozone, which can impair lung capacity, cause eye, nose and throat irritation, timber and other valuable crops such as soybeans and cotton. The health effects of exposure to HAPs can include cancer, respiratory irritation and damage to the nervous system. An additional set of standards promulgate national emission standards for hazardous air pollutants (NESHAP) under section 112 of the Act for marine tank vessel loading operations and require existing and new major sources to control emissions using maximum achievable control technology (MACT) to control HAP.
