Emissions Monitoring
What is 40 CFR Part 63?
The EPA 40 CFR Part 63 is a set of regulations established by the Environmental Protection Agency (EPA) for hazardous air pollutants not covered by National Ambient Air Quality Standards (NAAQS). Title 40 of the Code of Federal Regulations (CFR), Part 63, commonly known as “40 CFR Part 63,” is a set of regulations established by the United States Environmental Protection Agency (EPA). Specifically, Part 63 deals with National Emission Standards for Hazardous Air Pollutants (NESHAP) for various industries and processes. These regulations are designed to protect public health and the environment by limiting emissions of hazardous air pollutants (HAPs) from specific sources. Part 63 sets emission standards for different types of industrial facilities, such as chemical manufacturing plants, petroleum refineries, and other operations that release potentially harmful pollutants into the air.
Emissions monitoring is a critical component of compliance with these standards. Facilities subject to Part 63 regulations are required to implement control technologies and practices to minimize their emissions of HAPs. Monitoring of emissions is necessary to ensure that these control measures are effectively reducing pollutant releases to levels that meet or are below the specified regulatory limits.
Under EPA 40 CFR Part 63, facilities must install, operate, and maintain monitoring equipment to continuously or periodically measure emissions of hazardous air pollutants. This monitoring equipment may include devices such as continuous emission monitors (CEMs), stack gas analyzers, or other monitoring systems specified by the regulations.
Several global government agencies regulate pollutant emissions and target chemicals and prioritized them based on the level of concern:
- United States Environmental Protection Agency (EPA) Maintains the National Emissions Standards for Hazardous Air Pollutants (NESHAP) list, which identifies and regulates specific hazardous air pollutants.
- European Chemicals Agency (ECHA): Manages the Candidate List of Substances of Very High Concern (SVHC), which includes chemicals requiring authorization under the REACH regulation due to their hazardous properties.
- World Health Organization (WHO): Publishes guidelines on air quality, identifying key pollutants such as particulate matter, nitrogen dioxide, sulfur dioxide, ozone, and carbon monoxide.
- Agency for Toxic Substances and Disease Registry (ATSDR): Develops the Priority List of Hazardous Substances, which prioritizes substances based on their frequency, toxicity, and potential for human exposure.
- National Institute for Occupational Safety and Health (NIOSH): Maintains a list of immediately dangerous to life or health (IDLH) substances, which includes chemicals that pose an immediate threat to life or health.
- International Agency for Research on Cancer (IARC): Identifies and classifies chemicals with respect to their carcinogenicity, providing a valuable resource for assessing the cancer risk associated with various substances.
