HAP regulation standard?

HAP regulation standard?

• A. NAAQS ambient standards
• B. OSHA PEL standards
• C. MACT/NESHAP standards
• D. Clean Water Act standards

Answer: (C)

Hazardous air pollutants are regulated with MACT (Maximum Achievable Control Technology) standards, implemented as NESHAP (National Emission Standards for Hazardous Air Pollutants) for each source category under the Clean Air Act. These technology-based standards require facilities to apply the best available controls to minimize HAP emissions, reflecting the maximum achievable reduction for new and existing sources. This approach targets emissions at the source, rather than setting ambient concentration limits. In contrast, ambient air standards (NAAQS) define public-health targets for outdoor air, OSHA PELs govern workplace exposures, and the Clean Water Act sets limits on pollutants discharged to waterways. So the HAP regulation standard is MACT/NESHAP.
