NESHAP Series Pt. 1: What Is NESHAP (National Emission Standard for Airborne Pollutants)?

February 20, 2014

NESHAP Series Pt. 1

Although the EPA’s NESHAP (National Emission Standard for Airborne Pollutants) has been around since 2008, many companies either do not know much about it or do not know if the rule even applies to them.  We at Clean Air America are here to help you not only understand NESHAP and how to know if you apply and are in compliance; but to help filter the air in the facility to help comply with the EPA’s standards and increase workers safety.  In this multipart series we will discuss what NESHAP is, how to know if it applies to you, how to test your emissions, and how to get your company in compliance.


What Is It?

Since the beginning of industrial filtration, companies have taken smoke, dust, fumes, etc. produced during the manufacturing process and exhausted them to the outside and into the environment. As time has passed, EPA (Environmental Protection Agency) has enforced more regulations on such filtration. More recently, the EPA has enacted Rule 6x as part of its NESHAP (National Emission Standard for Hazardous Air Pollutants).  When the Clean Air Act was put in place, the EPA was able to develop air emission standards based on a list of 187 hazardous air pollutants. These pollutants are labeled as hazardous because they are known to produce serious health concerns such as cancer or birth defects. Introduced in 2008, the NESHAP has set high standards for many manufacturing processes. Within these are those who do metal fabrication, also known as Metal Finishing Hazardous Air Pollutants. These are defined as materials that contain 0.1% by weight cadmium, chromium, lead, or nickel; or 1.0% by weight manganese, the most common component of the welding process.
