The Clean Air Act (CAA) is the law that defines the EPA's responsibilities for protecting and improving the nation's air quality and the stratospheric ozone layer. Congress designed the CAA to protect public health and welfare from different types of air pollution caused by a diverse array of pollution sources.
The National Emission Standards for Hazardous Air Pollutants (NESHAP) has been created as an extension of the CAA to monitor the amount of hazardous air pollutants (HAPs) from stationary sources. Stationary sources of air pollution include but are not limited to factories, refineries, boilers, and power plants. Eliminating emissions of pollutants is the goal. However, the percentage of emissions that can be eliminated is often limited by the current level of technology that is available to industrial sectors. Therefore, the EPA developed Maximum Achievable Control Technology (MACT) standards to tackle this issue.
When setting their MACT standards, the EPA looks at the current level of emissions that are being achieved by the best-performing similar sources in that industry. These emission levels are then used to set a baseline known as the “MACT floor” for the new standard. When the EPA sets a MACT standard, sources must, at a minimum, achieve a level of emissions control throughout that industry that is at least equivalent to the MACT floor.
NESHAP Regulations and Inspections
NESHAP standards are industry specific, but they can also be chemical specific and manufacturing process specific. The chemical Benzene has a NESHAP for waste operations and a separate NESHAP for transfer operations. For wood products there is a NESHAP for wood preservation and another for wood furniture surface coating.
HAPs have a significant impact on air quality and public health. The EPA’s efforts to identify and address excess emissions continue through inspections of facilities to evaluate compliance.
Initial performance tests are required by all sources subject to NESHAP to demonstrate compliance.
Sources are also generally required to monitor control device operating parameters. In addition, sources may be required to install and operate continuous emission monitors to further demonstrate compliance.
How ERA Improves MACT/NESHAP Reporting for You
The methodology behind ERA’s software is built on total accuracy and rigorous data-gathering, basing reports on your facility’s measured, actual daily activities. This complete approach excludes the data-gaps present in other software packages.
