Specifications include, but are not limited to: A. Asbestos abatement in interior building spaces, covered walkways or porticos connecting buildings and on outdoor mechanical systems which condition indoor air (such as air handling units, air conditioners, cooling towers, etc.) is governed by rules established by the Illinois Department of Public Health (IDPH). This specification section addresses or references the requirements for complying with IDPH, the Occupation Safety and Health Administration (OSHA), the Environmental Protection Agency (EPA) National Emission Standards for Hazardous Air Pollutants (NESHAP), and the Cook County asbestos rules. Each and every rule requirement may not be restated in detail since trained, accredited, and licensed Contractors and individuals are required for this work and are presumed to be familiar with the relevant laws and rules. Full regulatory compliance is required, and is a part of the contract, whether specifically stated herein or not. B. Exterior building spaces are not subject to IDPH rules unless the abatement procedures involve interior spaces of the building. Roofing, window replacement, exterior transite sheeting, asbestos siding, asbestos-containing paint, caulking, glazing, flashings, cements, or other products installed on the building exterior are subject to OSHA and NESHAP rules which, in many cases are less rigorous than IDPH requirements. Abatement of these items is specified in this section. C. The Contractor must remove and properly dispose of all specified Asbestos-Containing Materials (ACM). Contract drawings provide information regarding the location and material description of ACM located on the property. The above mentioned work must be performed utilizing negative pressure enclosure system unless alternatively specified by the Project Designer in the related drawings or specifications. D. The scope of work includes the removal of friable ACM as listed in the Environmental Scope Sheets, including pre-cleaning, establishing regulated areas, isolating the work areas, protection of adjacent areas, containment when required, cleanup and decontamination to the specified clearance levels, proper packaging and disposal of wastes, and all other steps necessary to complete the scope of work.
