The 1990 amendments to the Clean Air Act CAAA mandate strict control and monitoring of industrial sources of various potential air pollutants. Shipyards are included in the group of industries coming under recent scrutiny by regulatory agencies. In addition to federal regulations, many states and localities have begun to develop their own, often more aggressive, air pollution programs, particularly in the area of air toxics. The extent of the impact of these regulations will depend primarily on the size and location of the individual shipyard. Initially, this project focused on the federal regulation concerning HAPs emitted from shipyards pursuant to Title III of the CAAA, but was expanded to include criteria pollutants and the potential of utilizing the data and developments of the project for Title V requirements, which apply to Federal air permits. Typical operations at shipyards that emit regulated pollutants include coating, degreasing, electroplating, welding, and abrasive blasting. Solvents used by shipyards in coating operations emit hazardous air pollutants in the form of EPA is required to regulate VOC emissions from coatings under the CAAA. The primary deliverable of the project was the development of a procedure, format, and database for identifying, characterizing, and quantifying Hazardous Air Pollutants HAPs and criteria pollutants NOX, SOx, VOC, PMI O, CO, and Lead emitted from various shipyard processes and equipment. An integral part of this effort was the development of a user-friendly and shipyard compatible database. The database inventories, characterizes, and quantifies the above regulated air contaminants from equipment and processes, and provides feasible, proven, and Environmental Protection Agency EPA approved control technologies for the various pollutants.
