ENVIRONET routinely performs ACM surveys for industrial and commercial real estate as part of our Phase I ESA scope of work.
We have completed assessment of several hundred structures targeted for demolition or renovation. Our NESHAPs report, provided to the demolition contractor or owner, includes the locations of materials tested, detailed description of location and condition, estimation as to linear feet or square feet of suspect material, photographs of the material, schematics of the structural lay-out of the building, laboratory results, chain-of-custody documentation, an assessor’s report for the building, and certifications of our licensed personnel.
The presence and condition of suspect ACM materials is documented in the ESA reports along with our recommendations to manage or remove the materials, as may be appropriate on a case-by-case basis. Structures targeted for demolition or significant remodeling require a full NESHAPS survey. EnviroNET‘s surveys follow the National Emissions Standard for Hazardous Air Pollutants (NESHAP) requirements to identify and quantify materials that must be managed during property renovation or demolition projects.
Types of asbestos.
A distinction is made between building materials that would readily release asbestos fibers when damaged or disturbed and those materials that were unlikely to result in significant fiber release. The terms “friable” and “non-friable” are used to make this distinction.
Friable asbestos-containing material, is defined by the Asbestos NESHAP, as any material containing more than one percent (1%) asbestos that, when dry, can be crumbled, pulverized or reduced to powder by hand pressure.
Non-friable asbestos-containing material is any material containing more than one percent (1%) asbestos that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure. EPA also defines two categories of nonfriable ACM, Category I and Category II nonfriable ACM
Non-friable asbestos containing material that has become friable when subjected to sanding, grinding, cutting or abrading.
Non-friable asbestos containing material that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations.
