The EPA established National Emissions Standards
for Hazardous Air Pollutants (NESHAP) to protect the public.
Asbestos was one of the first air hazardous pollutants to be
regulated by the EPA.
The Asbestos NESHAP regulations protect
the public by minimizing the release of asbestos fibers during
activities involving the processing, handling, and disposal of
asbestos-containing material. These activities may be either
the demolition or renovation of a building.
Encapsulation is the application of a sealant
material to an asbestos surface, which prevents the release of
fibers into the air. Normally, encapsulation is not regulated
by NESHAP. However if encapsulation were done using methods that
damage asbestos and release fibers the NESHAP regulations would
The ability of the encapsulant to be applied
without damaging the surface and remain in place for long periods
of exposure to environmental changes are critical to success
of the encapsulation process.
