Boatbuilders who use composites have, at most, just one more year before they have to reduce emissions to meet National Emission Standards for Hazardous Air Pollutants (NESH AP), also known as Maximum Achievable Control Technology (MACT) standards. By 23rd Aug. 2004, most boat manufacturing facilities subject to NESHAP must comply with 40 Code of Federal Regulations (CFR) Part 63, Subpart VVW. The deadline applies to existing boat manufacturing facilities that are major sources of hazardous air pollutants (HAPs). Existing sources are those that commenced construction on or before July 14, 2000. ( New sources , those that commenced construction after this date, must comply with emission limits at startup.) Major sources are facilities that have the potential to... 

Metals emissions, e.g., mercury emissions, in relation to EPA s hazardous waste combustion maximum achievable control technology (MACT) standards and a site-specific, risk-based analysis that is particularly focused on silver and other metals impacted by the formation of chlorinated and nitrated volatile metals. 

To limit the risk of hazardous air pollutant exposure over time, the EPA mandates that all major sources of HAP emissions operate under Maximum Achievable Control Technology (MACT) standards. The EPA intends to augment and add to the current list of MACT standards additionally, there are catch-aU regulations for all major sources of HAPs. One such example is the MACT Hammer, which allows states to implement MACT standards for industries not currently addressed by EPA definitions. A list of such MACT standards, including the Miscellaneous Organic NESHAP (MON), can be referenced at http //www.dep.state.pa.us/dep/deputate/airwaste/aq/permits/nes-haps/hammer table.pdf. 

National Emission Standards for Hazardous Air Pollutants (NESHAPS), Clean Air Act section 112 40 CFR Parts 61, 63, and 68. Includes an accidental release program, list of HAPS and sources, residual risk standards, and maximum achievable control technology (MACI standards. 

That standard was known as MACT - Maximum Achievable Control Technology. MACT standards are designed to reduce HAP emissions to a maximum achievable degree, taking into consideration the cost of emission reductions and other factors. 

The 1990 Clean Air Act Amendments Hst 189 hazardous air pollutants (HAPs) that the EPA must regulate to enforce maximum achievable control technology (MACT) to standards which are to be set by the year 2000. The 33/50 project calls for reduction of emissions of 17 specified solvents to predetermined levels by 1995. The SARA statute provides a mechanism by which the community can be informed of the existence, quantities, and releases of toxic chemicals, and requires that anyone releasing specific toxic chemicals above a threshold level to annually submit a toxic chemical release form to the EPA. The status of various ketones under these regulations is shown in Table 4. 

In the United States, the Clean Air Act of 1990 requires plants to reduce emissions of 189 toxic and carcinogenic substances such as chlorine, chloroform, and 2,3,7,8-TCDD (dioxin) by 90% over the 1990s. The U.S. Environmental Protection Agency is working to develop standards based on maximum achievable control technologies and the industry has invested bUHons of doUars in capital investments to retrofit or rebuUd plant equipment to meet these measures. 

CAAA90 is a technology-based program rather than the health-based program used in the original Clean Air Act. The standards and emission limits are based on maximum achievable control technology. The final emission lirnits will be set forth in permits issued by the individual states. 

An acid dipping operation for metal parts involves the use of a 75% strength sulfuric acid solution. Develop recommendations for the Maximum Achievable Control Technology for controlling the air emissions from such an operation. Hint Take some time to look at the EPA Web sites dealing with MACT standards and pollution prevention. 

Air toxics regulations apply to several parts of the pulp and paper milling process. National Emission Standards for Hazardous Air Pollutants (NESHAP) have been developed expressly for two processes of the pulp and paper industry. These standards establish process-based maximum achievable control technologies (MACT) for major sources, which are defined as facilities that emit or have the potential to emit 10 t per year or more of any hazardous air pollutant (HAP) or 25 t per year or more of any combination of HAPs. 

A survey is presented of developments by various U.S. manufacturers in gel coats, in-mould films and primers for composite materials which improve the composite fabricator s work environment and clean up community air quality, without compromising product performance. The coatings developed comply with the Environmental Protection Agency s standards on Maximum Achievable Control Technology for regulation of emission of hazardous air pollutants(HAPs). 

Intentions by the EPA to more tightly regulate the emission of hazardous air pollutants through maximum-achievable-control-technology standards are briefly reported with reference to styrene emissions. The regulation would require that any facility that emits more than 100 tons of styrene annually, should retrofit with expensive ventilation equipment, and that a new facility of any size would have to install the same type of equipment. The composites industry considers this to be an expensive standard, which could put companies out of work. 

Under the Clean Air Act Amendments of 1990, the mandate is to establish, during the first phase, technology-based maximum achievable control technology (MACT) emission standards that apply to the major categories or subcategories of sources of the listed hazardous air pollutants (EPA, 1997). In addition, Title III provides for health-based standards that address the issue of residual risks due to air toxic emissions from the sources equipped with MACT and to determine whether the MACT standards can protect health with an ample margin of safety. 

In 1995, the amendments to the Clean Air Act included requirements for maximum achievable control technology (MACT) for pollutants, including dioxins and metals. The EPA has since promulgated regulations that will have to be met by a modified baseline process for the Pueblo site (EPA, 1999). In addition, EPA is reviewing the effects of dioxins on human health because some evidence indicates dioxins may be more harmful in the food chain than previously thought (Kaiser, 2000). If dioxin emission standards are modified, analytical procedures will need to be reviewed. 

In October 2005, under authority of the Clean Air Act and RCRA, the EPA issued its final national emission standards for hazardous air pollutants from hazardous waste combustors. The standards require hazardous waste combustors to meet hazardous air pollutant emission standards reflecting the application of maximum achievable controllable technology (MACT). These standards are applicable to any hazardous waste incinerator, including the chemical agent disposal facilities. In some states, separate air permits are issued to hazardous waste incinerators, while in others the RCRA permit requirements are adopted or changed to implement the requirements of the new MACT emissions standards for controlling the following pollutants ... 

In October 2005, the EPA issued a final rule updating the RCRA emission standards for hazardous waste incinerators based on maximum achievable control technology (MACT) that is commonly employed under the CAA. Therefore, hazardous waste incinerators are subject to MACT combustion unit performance standards and operating requirements, in addition to RCRA standards.
