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.

FLARE GAS ANALYSIS
A gas flare is a gas combustion control used in petroleum refineries, chemical plants and natural gas processing plants. flare stacks are primarily used for burning off flammable gas released by safety valves during unplanned over-pressuring of plant equipment. The emissions are made up of both inorganic and organic species. Flaring releases methane, a potent greenhouse gas, into the atmosphere.
Flaring releases various pollutants, including greenhouse gases (GHGs) such as carbon dioxide (CO2), methane (CH4), and other volatile organic compounds (VOCs) into the atmosphere. Flare gas analysis helps quantify the emissions by measuring the concentration of these gases. Accurate emission quantification is crucial for evaluating the environmental impact, assessing compliance with regulatory requirements, and establishing baseline data for emission reduction efforts.
Flare gas analysis allows for the assessment of flare combustion efficiency. Incomplete or inefficient combustion during flaring can lead to the formation of pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and soot. By analyzing the composition of flare gas, operators can evaluate the combustion efficiency, identify any areas of improvement, and optimize flare operation to minimize the formation of pollutants.

BENZENE & FENCELINE MONITORING
Benzene is a highly hazardous chemical known to cause serious health effects, including cancer, when exposed to high concentrations or for prolonged periods. Refineries often have workers in close proximity to benzene sources, such as storage tanks, process units, or transfer areas. Fenceline monitoring helps ensure that workers are not exposed to excessive levels of benzene, providing a safer working environment and minimizing the risk of occupational illnesses.
Fugitive emissions are a significant source of pollution and produced by industry, refineries, energy production, and natural gas pipelines. 40 CFR § 63.658 fenceline monitoring was created to better protect and inform nearby communities, while also strengthening emission controls for flares, pressure relief devices, storage tanks, and delayed coker operations. Its purpose is to reduce hazardous air pollutants by requiring the sites to sample along the facility property boundary to measure the ambient air concentration of a specific chemical at the property line of the manufacturing site.
Refinery benzene fenceline monitoring plays a vital role in ensuring compliance with the Refinery Sector Rule (RSR), which is a set of regulations established by the U.S. Environmental Protection Agency (EPA) to reduce emissions and protect the environment and public health from harmful air pollutants emitted by petroleum refineries.
