PART 763_ASBESTOS--Table of Contents
 
           Subpart E_Asbestos-Containing Materials in Schools
 
Sec. 763.83  Definitions.

    For purposes of this subpart:
    Act means the Toxic Substances Control Act (TSCA), 15 U.S.C. 2601, 
et seq.
    Accessible when referring to ACM means that the material is subject 
to disturbance by school building occupants or custodial or maintenance 
personnel in the course of their normal activities.
    Accredited or accreditation when referring to a person or laboratory 
means that such person or laboratory is accredited in accordance with 
section 206 of Title II of the Act.
    Air erosion means the passage of air over friable ACBM which may 
result in the release of asbestos fibers.
    Asbestos means the asbestiform varieties of: Chrysotile 
(serpentine); crocidolite (riebeckite); amosite (cum- 
mingtonitegrunerite); anthophyllite; tremolite; and actinolite.
    Asbestos-containing material (ACM) when referring to school 
buildings means any material or product which contains more than 1 
percent asbestos.
    Asbestos-containing building material (ACBM) means surfacing ACM, 
thermal system insulation ACM, or miscellaneous ACM that is found in or 
on interior structural members or other parts of a school building.
    Asbestos debris means pieces of ACBM that can be identified by 
color, texture, or composition, or means dust, if the dust is determined 
by an accredited inspector to be ACM.
    Damaged friable miscellaneous ACM means friable miscellaneous ACM 
which has deteriorated or sustained physical injury such that the 
internal structure (cohesion) of the material is inadequate or, if 
applicable, which has delaminated such that its bond to the substrate 
(adhesion) is inadequate or which for any other reason lacks fiber 
cohesion or adhesion qualities. Such damage or deterioration may be 
illustrated by the separation of ACM into layers; separation of ACM from 
the substrate; flaking, blistering, or crumbling of the ACM surface; 
water damage; significant or repeated water stains, scrapes, gouges, 
mars or other signs of physical injury on the ACM. Asbestos debris 
originating from the ACBM in question may also indicate damage.
    Damaged friable surfacing ACM means friable surfacing ACM which has 
deteriorated or sustained physical injury such that the internal 
structure (cohesion) of the material is inadequate or which has 
delaminated such that its bond to the substrate (adhesion) is 
inadequate, or which, for any other reason, lacks fiber cohesion or 
adhesion qualities. Such damage or deterioration may be illustrated by 
the separation of ACM into layers; separation of ACM from the substrate; 
flaking, blistering, or crumbling of the ACM surface; water damage; 
significant or repeated water stains, scrapes, gouges, mars or other 
signs of physical injury on the ACM. Asbestos debris originating from 
the ACBM in question may also indicate damage.
    Damaged or significantly damaged thermal system insulation ACM means 
thermal system insulation ACM on pipes, boilers, tanks, ducts, and other 
thermal system insulation equipment where the insulation has lost its 
structural integrity, or its covering, in whole or in part, is crushed, 
water-stained, gouged, punctured, missing, or not intact such that it is 
not able to contain fibers. Damage may be further illustrated by 
occasional punctures, gouges or other signs of physical injury to ACM; 
occasional water damage on the protective coverings/jackets; or exposed 
ACM ends or joints. Asbestos debris originating from the ACBM in 
question may also indicate damage.
    Encapsulation means the treatment of ACBM with a material that 
surrounds or embeds asbestos fibers in an adhesive matrix to prevent the 
release of fibers, as the encapsulant creates a membrane over the 
surface (bridging encapsulant) or penetrates the material and binds its 
components together (penetrating encapsulant).
    Enclosure means an airtight, impermeable, permanent barrier around

[[Page 730]]

ACBM to prevent the release of asbestos fibers into the air.
    Fiber release episode means any uncontrolled or unintentional 
disturbance of ACBM resulting in visible emission.
    Friable when referring to material in a school building means that 
the material, when dry, may be crumbled, pulverized, or reduced to 
powder by hand pressure, and includes previously nonfriable material 
after such previously nonfriable material becomes damaged to the extent 
that when dry it may be crumbled, pulverized, or reduced to powder by 
hand pressure.
    Functional space means a room, group of rooms, or homogeneous area 
(including crawl spaces or the space between a dropped ceiling and the 
floor or roof deck above), such as classroom(s), a cafeteria, gymnasium, 
hallway(s), designated by a person accredited to prepare management 
plans, design abatement projects, or conduct response actions.
    High-efficiency particulate air (HEPA) refers to a filtering system 
capable of trapping and retaining at least 99.97 percent of all 
monodispersed particles 0.3 [micro]m in diameter or larger.
    Homogeneous area means an area of surfacing material, thermal system 
insulation material, or miscellaneous material that is uniform in color 
and texture.
    Local education agency means:
    (1) Any local educational agency as defined in section 198 of the 
Elementary and Secondary Education Act of 1965 (20 U.S.C. 3381).
    (2) The owner of any nonpublic, nonprofit elementary, or secondary 
school building.
    (3) The governing authority of any school operated under the defense 
dependent's education system provided for under the Defense Dependents' 
Education Act of 1978 (20 U.S.C. 921, et seq.).
    Miscellaneous ACM means miscellaneous material that is ACM in a 
school building.
    Miscellaneous material means interior building material on 
structural components, structural members or fixtures, such as floor and 
ceiling tiles, and does not include surfacing material or thermal system 
insulation.
    Nonfriable means material in a school building which when dry may 
not be crumbled, pulverized, or reduced to powder by hand pressure.
    Operations and maintenance program means a program of work practices 
to maintain friable ACBM in good condition, ensure clean up of asbestos 
fibers previously released, and prevent further release by minimizing 
and controlling friable ACBM disturbance or damage.
    Potential damage means circumstances in which:
    (1) Friable ACBM is in an area regularly used by building occupants, 
including maintenance personnel, in the course of their normal 
activities.
    (2) There are indications that there is a reasonable likelihood that 
the material or its covering will become damaged, deteriorated, or 
delaminated due to factors such as changes in building use, changes in 
operations and maintenance practices, changes in occupancy, or recurrent 
damage.
    Potential significant damage means circumstances in which:
