[FRL-4893-5]
Interpretive Rule for Roof Removal Operations Under the Asbestos
NESHAP
AGENCY: Environmental Protection Agency.
ACTION: Interpretive rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (``EPA'') is today
publishing an interpretive rule regarding roof removal operations under
the National Emission Standards for Hazardous Air Pollutants for
Asbestos (``Asbestos NESHAP''). The purpose of the interpretive rule is
to clarify the Asbestos NESHAP as it affects roof removal operations
by: specifying which roof removal operations EPA construes the NESHAP
to cover; and specifying roof removal work practices that EPA deems to
be in compliance with the NESHAP in roofing operations where the NESHAP
applies.
EFFECTIVE DATE: June 17, 1994.
FOR FURTHER INFORMATION CONTACT: Mr. Thomas Ripp at (703) 308-8727 at
U.S. Environmental Protection Agency, Office of Air Quality Planning
and Standards, Stationary Source Compliance Division. For copies,
contact Mr. Larry Tessier at 1-800-368-5888 or at (703) 305-5938.
SUPPLEMENTARY INFORMATION: On November 20, 1990, EPA published in the
Federal Register (55 FR 48406) revisions to the Asbestos NESHAP, which
is codified at 40 CFR part 61, subpart M. Members of the roofing
industry have expressed confusion regarding the asbestos NESHAP and
have requested clarification from EPA with regard to how compliance
with the NESHAP can be achieved for roof removal operations.
EPA is today publishing, as a new appendix A to subpart M of 40 CFR
part 61, the interpretive rule that is set forth below. The purpose of
the interpretive rule is to clarify the Asbestos NESHAP as it affects
roof removal operations by: (i) Specifying which roof removal
operations EPA construes the NESHAP to cover; and (ii) specifying roof
removal work practices that EPA deems to be in compliance with the
NESHAP in roofing operations where the NESHAP applies.
The new appendix A to the Asbestos NESHAP does not supersede, alter
or replace the Asbestos NESHAP; nor does it change the scope or
stringency of the NESHAP. Rather appendix A interprets the NESHAP as it
applies to roof removal operations, in order to provide particularized
guidance which, if followed, would promote compliance with, and more
effective and consistent enforcement of, the NESHAP in such operations.
This interpretive rule is intended as guidance to the roofing industry
and the public and does not constitute an action which is subject to
judicial review under section 307(b)(1) of the Clean Air Act, 42 U.S.C.
7607(b)(1), or under the Administrative Procedure Act, 5 U.S.C. 704. In
addition, because the rule prescribed in this notice is an interpretive
rule and does not promulgate or revise a standard or regulation listed
in section 307(d)(1) of the Clean Air Act (42 U.S.C. 7607(d)(1)), the
procedural requirements for rulemaking under the Clean Air Act and the
Administrative Procedure Act do not apply to this action. See 42 U.S.C.
7607(d); 5 U.S.C. 553(b).
It is the present intent of EPA that if this interpretive rule is
revoked or withdrawn before new regulations regarding asbestos
emissions or work practices for handling of asbestos containing
materials during roof removal operations under the Clean Air Act are
promulgated by EPA, then EPA shall replace the interpretive rule with
another interpretation or guidance document that would address how the
NESHAP applies to roof removal in renovation and demolition operations.
It is also the present intent of EPA that prior to replacing or
substantially revising this interpretive rule, EPA would consult with
the public regarding such action.

Authority: Secs. 101, 112, 114, 116, 301, Clean Air Act as
amended (42 U.S.C. 7401, 7412, 7414, 7416, 7601).
Subpart M--[Amended]
2. Appendix A is added to subpart M to read as follows:
Appendix A to Subpart M--Interpretive Rule Governing Roof Removal
Operations
I. Applicability of the Asbestos NESHAP
1.1. Asbestos-containing material (ACM) is material containing
more than one percent asbestos as determined using the methods
specified in appendix A, subpart F, 40 CFR part 763, section 1,
Polarized Light Microscopy. The NESHAP classifies ACM as either
``friable'' or ``nonfriable''. Friable ACM is ACM that, when dry,
can be crumbled, pulverized or reduced to powder by hand pressure.
Nonfriable ACM is ACM that, when dry, cannot be crumbled, pulverized
or reduced to powder by hand pressure.
1.2. Nonfriable ACM is further classified as either Category I
ACM or Category II ACM. Category I ACM and Category II ACM are
distinguished from each other by their potential to release fibers
when damaged. Category I ACM includes asbestos-containing gaskets,
packings, resilient floor coverings, resilient floor covering
mastic, and asphalt roofing products containing more than one
percent asbestos. Asphalt roofing products which may contain
asbestos include built-up roofing; asphalt-containing single ply
membrane systems; asphalt shingles; asphalt-containing underlayment
felts; asphalt-containing roof coatings and mastics; and asphalt-
containing base flashings. ACM roofing products that use other
bituminous or resinous binders (such as coal tars or pitches) are
also considered to be Category I ACM. Category II ACM includes all
other nonfriable ACM, for example, asbestos-cement (A/C) shingles,
A/C tiles, and transite boards or panels containing more than one
percent asbestos. Generally speaking, Category II ACM is more likely
to become friable when damaged than is Category I ACM. The
applicability of the NESHAP to Category I and II ACM depends on: (1)
the condition of the material at the time of demolition or
renovation, (2) the nature of the operation to which the material
will be subjected, (3) the amount of ACM involved.
1.3. Asbestos-containing material regulated under the NESHAP is
referred to as ``regulated asbestos-containing material'' (RACM).
RACM is defined in Sec. 61.141 of the NESHAP and includes: (1)
friable asbestos-containing material; (2) Category I nonfriable ACM
that has become friable; (3) Category I nonfriable ACM that has been
or will be sanded, ground, cut, or abraded; or (4) Category II
nonfriable ACM that has already been or is likely to become
crumbled, pulverized, or reduced to powder. If the coverage
threshold for RACM is met or exceeded in a renovation or demolition
operation, then all friable ACM in the operation, and in certain
situations, nonfriable ACM in the operation, are subject to the
NESHAP.
A. Threshold Amounts of Asbestos-Containing Roofing Material
1.A.1. The NESHAP does not cover roofing projects on single
family homes or on residential buildings containing four or fewer
dwelling units. 40 CFR 61.141. For other roofing renovation
projects, if the total asbestos-containing roof area undergoing
renovation is less than 160 ft2, the NESHAP does not apply,
regardless of the removal method to be used, the type of material
(Category I or II), or its condition (friable versus nonfriable). 40
CFR 61.145(a)(4). However, EPA would recommend the use of methods
that damage asbestos-containing roofing material as little as
possible. EPA has determined that where a rotating blade (RB) roof
cutter or equipment that similarly damages the roofing material is
used to remove Category I nonfriable asbestos-containing roofing
material, the removal of 5580 ft2 of that material will create
160 ft2 of RACM. For the purposes of this interpretive rule,
``RB roof cutter'' means an engine-powered roof cutting machine with
one or more rotating cutting blades the edges of which are blunt.
(Equipment with blades having sharp or tapered edges, and/or which
does not use a rotating blade, is used for ``slicing'' rather than
``cutting'' the roofing material; such equipment is not included in
the term ``RB roof cutter''.) Therefore, it is EPA's interpretation
that when an RB roof cutter or equipment that similarly damages the
roofing material is used to remove Category I nonfriable asbestos-
containing roofing material, any project that is 5580 ft2 or
greater is subject to the NESHAP; conversely, it is EPA's
interpretation that when an RB roof cutter or equipment that
similarly damages the roofing material is used to remove Category I
nonfriable asbestos-containing roofing material in a roof removal
project that is less than 5580 ft2, the project is not subject
to the NESHAP, except that notification is always required for
demolitions. EPA further construes the NESHAP to mean that if
slicing or other methods that do not sand, grind, cut or abrade will
be used on Category I nonfriable ACM, the NESHAP does not apply,
regardless of the area of roof to be removed.
1.A.2. For asbestos cement (A/C) shingles (or other Category II
roofing material), if the area of the roofing material to be removed
is at least 160 ft2 and the removal methods will crumble,
pulverize, reduce to powder, or contaminate with RACM (from other
ACM that has been crumbled, pulverized or reduced to powder) 160
ft2 or more of such roofing material, the removal is subject to
the NESHAP. Conversely, if the area of the A/C shingles (or other
Category II roofing materials) to be removed is less than 160
ft2, the removal is not subject to the NESHAP regardless of the
removal method used, except that notification is always required for
demolitions. 40 CFR 61.145(a). However, EPA would recommend the use
of methods that damage asbestos-containing roofing material as
little as possible. If A/C shingles (or other Category II roofing
materials) are removed without 160 ft2 or more of such roofing
material being crumbled, pulverized, reduced to powder, or
contaminated with RACM (from other ACM that has been crumbled,
pulverized or reduced to powder), the operation is not subject to
the NESHAP, even where the total area of the roofing material to be
removed exceeds 160 ft2; provided, however, that if the
renovation includes other operations involving RACM, the roof
removal operation is covered if the total area of RACM from all
renovation activities exceeds 160 ft2. See the definition of
regulated asbestos-containing material (RACM), 40 CFR 61.141.
1.A.3. Only roofing material that meets the definition of ACM
can qualify as RACM subject to the NESHAP. Therefore, to determine
if a removal operation that meets or exceeds the coverage threshold
is subject to the NESHAP, any suspect roofing material (i.e. roofing
material that may be ACM) should be tested for asbestos. If any such
roofing material contains more than one percent asbestos and if the
removal operation is covered by the NESHAP, then EPA must be
notified and the work practices in Sec. 61.145(c) must be followed.
In EPA's view, if a removal operation involves at least the
threshold level of suspect material, a roofing contractor may choose
not to test for asbestos if the contractor follows the notification
and work practice requirements of the NESHAP.
B. A/C Shingle Removal (Category II ACM Removal)
1.B.1. A/C shingles, which are Category II nonfriable ACM,
become regulated ACM if the material 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. 40 CFR 61.141. However, merely
breaking an A/C shingle (or any other category II ACM) that is not
friable may not necessarily cause the material to become RACM. A/C
shingles are typically nailed to buildings on which they are
attached. EPA believes that the extent of breakage that will
normally result from carefully removing A/C shingles and lowering
the shingles to the ground will not result in crumbling, pulverizing
or reducing the shingles to powder. Conversely, the extent of
breakage that will normally occur if the A/C shingles are dropped
from a building or scraped off of a building with heavy machinery
would cause the shingles to become RACM. EPA therefore construes the
NESHAP to mean that the removal of A/C shingles that are not
friable, using methods that do not crumble, pulverize, or reduce the
A/C shingles to powder (such as pry bars, spud bars and shovels to
carefully pry the material), is not subject to the NESHAP provided
that the A/C shingles are properly handled during and after removal,
as discussed in this paragraph and the asbestos NESHAP. This
interpretation also applies to other Category II nonfriable
asbestos-containing roofing materials.
C. Cutting vs. Slicing and Manual Methods for Removal of Category I ACM
1.C.1. Because of damage to the roofing material, and the
potential for fiber release, roof removal operations using rotating
blade (RB) roof cutters or other equipment that sand, grind, cut or
abrade the roof material are subject to the NESHAP. As EPA
interprets the NESHAP, the use of certain manual methods (using
equipment such as axes, hatchets, or knives, spud bars, pry bars,
and shovels, but not saws) or methods that slice, shear, or punch
(using equipment such as a power slicer or power plow) does not
constitute ``cutting, sanding, grinding or abrading.'' This is
because these methods do not destroy the structural matrix or
integrity of the material such that the material is crumbled,
pulverized or reduced to powder. Hence, it is EPA's interpretation
that when such methods are used, assuming the roof material is not
friable, the removal operation is not subject to the regulation.
1.C.2. Power removers or power tear-off machines are typically
used to pry the roofing material up from the deck after the roof
membrane has been cut. It is EPA's interpretation that when these
machines are used to pry roofing material up, their use is not
regulated by the NESHAP.
1.C.3. As noted previously, the NESHAP only applies to the
removal of asbestos-containing roofing materials. Thus, the NESHAP
does not apply to the use of RB cutters to remove non-asbestos built
up roofing (BUR). On roofs containing some asbestos-containing and
some non-asbestos containing materials, coverage under the NESHAP
depends on the methods used to remove each type of material in
addition to other coverage thresholds specified above. For example,
it is not uncommon for existing roofs to be made of non-asbestos BUR
and base flashings that do contain asbestos. In that situation, EPA
construes the NESHAP to be inapplicable to the removal of the non-
asbestos BUR using an RB cutter so long as the RB cutter is not used
to cut 5580 ft\2\ or more of the asbestos-containing base flashing
or other asbestos-containing material into sections. In addition,
the use of methods that slice, shear, punch or pry could then be
used to remove the asbestos flashings and not trigger coverage under
the NESHAP.
II. Notification
2.1. Notification for a demolition is always required under the
NESHAP. However, EPA believes that few roof removal jobs constitute
``demolitions'' as defined in the NESHAP (Sec. 61.141). In
particular, it is EPA's view that the removal of roofing systems
(i.e., the roof membrane, insulation, surfacing, coatings,
flashings, mastic, shingles, and felt underlayment), when such
removal is not a part of a demolition project, constitutes a
``renovation'' under the NESHAP. If the operation is a renovation,
and Category I roofing material is being removed using either manual
methods or slicing, notification is not required by the NESHAP. If
Category II material is not friable and will be removed without
crumbling, pulverizing, or reducing it to powder, no notification is
required. Also, if the renovation involves less than the threshold
area for applicability as discussed above, then no notification is
required. However, if a roof removal meets the applicability and
threshold requirements under the NESHAP, then EPA (or the delegated
agency) must be notified in advance of the removal in accordance
with the requirements of Sec. 61.145(b), as follows:
Notification must be given in writing at least 10
working days in advance and must include the information in
Sec. 61.145(b)(4), except for emergency renovations as discussed
below.
The notice must be updated as necessary, including, for
example, when the amount of asbestos-containing roofing material
reported changes by 20 percent or more.
EPA must be notified if the start date of the roof
removal changes. If the start date of a roof removal project is
changed to an earlier date, EPA must be provided with a written
notice of the new start date at least 10 working days in advance. If
the start date changes to a later date, EPA must be notified by
telephone as soon as possible before the original start date and a
written notice must be sent as soon as possible.
For emergency renovations (as defined in Sec. 61.141),
where work must begin immediately to avoid safety or public health
hazards, equipment damage, or unreasonable financial burden, the
notification must be postmarked or delivered to EPA as soon as
possible, but no later than the following work day.
III. Emission Control Practices
A. Requirements to Adequately Wet and Discharge No Visible Emission
3.A.1. The principal controls contained in the NESHAP for
removal operations include requirements that the affected material
be adequately wetted, and that asbestos waste be handled, collected,
and disposed of properly. The requirements for disposal of waste
materials are discussed separately in section IV below. The emission
control requirements discussed in this section III apply only to
roof removal operations that are covered by the NESHAP as set forth
in Section I above.
3.A.2. For any operation subject to the NESHAP, the regulation
(Secs. 61.145(c)(2)(i), (3), (6)(i)) requires that RACM be
adequately wet (as defined in Sec. 61.141) during the operation that
damages or disturbs the asbestos material until collected for
disposal.
3.A.3. When using an RB roof cutter (or any other method that
sands, grinds, cuts or abrades the roofing material) to remove
Category I asbestos-containing roofing material, the emission
control requirements of Sec. 61.145(c) apply as discussed in Section
I above. EPA will consider a roof removal project to be in
compliance with the ``adequately wet'' and ``discharge no visible
emission'' requirements of the NESHAP if the RB roof cutter is
equipped and operated with the following: (1) a blade guard that
completely encloses the blade and extends down close to the roof
surface; and (2) a device for spraying a fine mist of water inside
the blade guard, and which device is in operation during the cutting
of the roof.
B. Exemptions From Wetting Requirements
3.B.1. The NESHAP provides that, in certain instances, wetting
may not be required during the cutting of Category I asbestos
roofing material with an RB roof cutter. If EPA determines in
accordance with Sec. 61.145(c)(3)(i), that wetting will unavoidably
damage the building, equipment inside the building, or will present
a safety hazard while stripping the ACM from a facility component
that remains in place, the roof removal operation will be exempted
from the requirement to wet during cutting. EPA must have sufficient
written information on which to base such a decision. Before
proceeding with a dry removal, the contractor must have received
EPA's written approval. Such exemptions will be made on a case-by-
case basis.
3.B.2. It is EPA's view that, in most instances, exemptions from
the wetting requirements are not necessary. Where EPA grants an
exemption from wetting because of the potential for damage to the
building, damage to equipment within the building or a safety
hazard, the NESHAP specifies alternative control methods
(Sec. 61.145(c)(3)(i)(B)). Alternative control methods include (a)
the use of local exhaust ventilation systems that capture the dust,
and do not produce visible emissions, or (b) methods that are
designed and operated in accordance with the requirements of
Sec. 61.152, or (c) other methods that have received the written
approval of EPA. EPA will consider an alternative emission control
method in compliance with the NESHAP if the method has received
written approval from EPA and the method is being implemented
consistent with the approved procedures (Sec. 61.145(c)(3)(ii) or
Sec. 61.152(b)(3)).
3.B.3. An exemption from wetting is also allowed when the air or
roof surface temperature at the point of wetting is below freezing,
as specified in Sec. 61.145(c)(7). If freezing temperatures are
indicated as the reason for not wetting, records must be kept of the
temperature at the beginning, middle and end of the day on which
wetting is not performed and the records of temperature must be
retained for at least 2 years. 42 CFR Sec. 61.145(c)(7)(iii). It is
EPA's interpretation that in such cases, no written application to,
or written approval by the Administrator is needed for using
emission control methods listed in Sec. 61.145(c)(3)(i)(B), or
alternative emission control methods that have been previously
approved by the Administrator. However, such written application or
approval is required for alternative emission control methods that
have not been previously approved. Any dust and debris collected
from cutting must still be kept wet and placed in containers. All of
the other requirements for notification and waste disposal would
continue to apply as described elsewhere in this notice and the
Asbestos NESHAP.
C. Waste Collection and Handling
3.C.1. It is EPA's interpretation that waste resulting from
slicing and other methods that do not cut, grind, sand or abrade
Category I nonfriable asbestos-containing roofing material is not
subject to the NESHAP and can be disposed of as nonasbestos waste.
EPA further construes the NESHAP to provide that if Category II
roofing material (such as A/C shingles) is removed and disposed of
without crumbling, pulverizing, or reducing it to powder, the waste
from the removal is not subject to the NESHAP waste disposal
requirements. EPA also interprets the NESHAP to be inapplicable to
waste resulting from roof removal operations that do not meet or
exceed the coverage thresholds described in section I above. Of
course, other State, local, or Federal regulations may apply.
3.C.2. It is EPA's interpretation that when an RB roof cutter,
or other method that similarly damages the roofing material, is used
to cut Category I asbestos containing roofing material, the damaged
material from the cut (the sawdust or debris) is considered asbestos
containing waste subject to Sec. 61.150 of the NESHAP, provided the
coverage thresholds discussed above in section 1 are met or
exceeded. This sawdust or debris must be disposed of at a disposal
site operated in accordance with the NESHAP. It is also EPA's
interpretation of the NESHAP that if the remainder of the roof is
free of the sawdust and debris generated by the cutting, or if such
sawdust or debris is collected as discussed below in paragraphs
3.C.3, 3.C.4, 3.C.5 and 3.C.6, the remainder of the roof can be
disposed of as nonasbestos waste because it is considered to be
Category I nonfriable material (as long as the remainder of the roof
is in fact nonasbestos material or if it is Category I asbestos
material and the removal methods do not further sand, grind, cut or
abrade the roof material). EPA further believes that if the roof is
not cleaned of such sawdust or debris, i.e., it is contaminated,
then it must be treated as asbestos-containing waste material and be
handled in accordance with Sec. 61.150.
3.C.3. In order to be in compliance with the NESHAP while using
an RB roof cutter (or device that similarly damages the roofing
material) to cut Category I asbestos containing roofing material,
the dust and debris resulting from the cutting of the roof should be
collected as soon as possible after the cutting operation, and kept
wet until collected and placed in leak-tight containers. EPA
believes that where the blade guard completely encloses the blade
and extends down close to the roof surface and is equipped with a
device for spraying a fine mist of water inside the blade guard, and
the spraying device is in operation during the cutting, most of the
dust and debris from cutting will be confined along the cut. The
most efficient methods to collect the dust and debris from cutting
are to immediately collect or vacuum up the damaged material where
it lies along the cut using a filtered vacuum cleaner or debris
collector that meets the requirements of 40 CFR 61.152 to clean up
as much of the debris as possible, or to gently sweep up the bulk of
the debris, and then use a filtered vacuum cleaner that meets the
requirements of 40 CFR 61.152 to clean up as much of the remainder
of the debris as possible. On smooth surfaced roofs (nonaggregate
roofs), sweeping up the debris and then wet wiping the surface may
be done in place of using a filtered vacuum cleaner. It is EPA's
view that if these decontamination procedures are followed, the
remaining roofing material does not have to be collected and
disposed of as asbestos waste. Additionally, it is EPA's view that
where such decontamination procedures are followed, if the remaining
portions of the roof are non-asbestos or Category I nonfriable
asbestos material, and if the remaining portions are removed using
removal methods that slice, shear, punch or pry, as discussed in
section 1.C above, then the remaining portions do not have to be
collected and disposed of as asbestos waste and the NESHAP's no
visible emissions and adequately wet requirements are not applicable
to the removal of the remaining portions. In EPA's interpretation,
the failure of a filtered vacuum cleaner or debris collector to
collect larger chunks or pieces of damaged roofing material created
by the RB roof cutter does not require the remaining roofing
material to be handled and disposed of as asbestos waste, provided
that such visible chunks or pieces of roofing material are collected
(e.g. by gentle sweeping) and disposed of as asbestos waste. Other
methods of decontamination may not be adequate, and should be
approved by the local delegated agency.
3.C.4. In EPA's interpretation, if the debris from the cutting
is not collected immediately, it will be necessary to lightly mist
the dust or debris, until it is collected, as discussed above, and
placed in containers. The dust or debris should be lightly misted
frequently enough to prevent the material from drying, and to
prevent airborne emissions, prior to collection as described above.
It is EPA's interpretation of the NESHAP that if these procedures
are followed, the remaining roofing material does not have to be
collected and disposed of as asbestos waste, as long as the
remaining roof material is in fact nonasbestos material or if it is
Category I asbestos material and the removal methods do not further
sand, grind, cut or abrade the roof material.
3.C.5. It is EPA's interpretation that, provided the roofing
material is not friable prior to the cutting operation, and provided
the roofing material has not been made friable by the cutting
operation, the appearance of rough, jagged or damaged edges on the
remaining roofing material, due to the use of an RB roof cutter,
does not require that such remaining roofing material be handled and
disposed of as asbestos waste. In addition, it is also EPA's
interpretation that if the sawdust or debris generated by the use of
an RB roof cutter has been collected as discussed in paragraphs
3.C.3, 3.C.4 and 3.C.6, the presence of dust along the edge of the
remaining roof material does not render such material ``friable''
for purposes of this interpretive rule or the NESHAP, provided the
roofing material is not friable prior to the cutting operation, and
provided that the remaining roofing material near the cutline has
not been made friable by the cutting operation. Where roofing
material near the cutline has been made friable by the use of the RB
cutter (i.e. where such remaining roofing material near the cutline
can be crumbled, pulverized or reduced to powder using hand
pressure), it is EPA's interpretation that the use of an encapsulant
will ensure that such friable material need not be treated or
disposed of as asbestos containing waste material. The encapsulant
may be applied to the friable material after the roofing material
has been collected into stacks for subsequent disposal as
nonasbestos waste. It is EPA's view that if the encapsulation
procedure set forth in this paragraph is followed in operations
where roofing material near the cutline has been rendered friable by
the use of an RB roof cutter, and if the decontamination procedures
set forth in paragraph 3.C.3 have been followed, the NESHAP's no
visible emissions and adequately wet requirements would be met for
the removal, handling and disposal of the remaining roofing
material.
3.C.6. As one way to comply with the NESHAP, the dust and debris
from cutting can be placed in leak-tight containers, such as plastic
bags, and the containers labeled using warning labels required by
OSHA (29 CFR 1926.58). In addition, the containers must have labels
that identify the waste generator (such as the name of the roofing
contractor, abatement contractor, and/or building owner or operator)
and the location of the site at which the waste was generated.
IV. Waste Disposal
A. Disposal Requirements
4.A.1. Section 61.150(b) requires that, as soon as is practical,
all collected dust and debris from cutting as well as any
contaminated roofing squares, must be taken to a landfill that is
operated in accordance with Sec. 61.154 or to an EPA-approved site
that converts asbestos waste to nonasbestos material in accordance
with Sec. 61.155. During the loading and unloading of affected
waste, asbestos warning signs must be affixed to the vehicles.
B. Waste Shipment Record
4.B.1. For each load of asbestos waste that is regulated under
the NESHAP, a waste shipment record (WSR) must be maintained in
accordance with Sec. 61.150(d). Information that must be maintained
for each waste load includes the following:
Name, address, and telephone number of the waste
generator
Name and address of the local, State, or EPA regional
office responsible for administering the asbestos NESHAP program
Quantity of waste in cubic meters (or cubic yards)
Name and telephone number of the disposal site operator
Name and physical site location of the disposal site
Date transported
Name, address, and telephone number of the
transporter(s)
Certification that the contents meet all government
regulations for transport by highways.
4.B.2. The waste generator is responsible for ensuring that a
copy of the WSR is delivered to the disposal site along with the
waste shipment. If a copy of the WSR signed by the disposal site
operator is not returned to the waste generator within 35 days, the
waste generator must contact the transporter and/or the disposal
site to determine the status of the waste shipment. 40 CFR
61.150(d)(3). If the signed WSR is not received within 45 days, the
waste generator must report, in writing, to the responsible NESHAP
program agency and send along a copy of the WSR. 40 CFR
61.150(d)(4). Copies of WSRs, including those signed by the disposal
site operator, must be retained for at least 2 years. 40 CFR
61.150(d)(5).
V. Training
5.1. For those roof removals that are subject to the NESHAP, at
least one on-site supervisor trained in the provisions of the NESHAP
must be present during the removal of the asbestos roofing material.
40 CFR 61.145(c)(8). In EPA's view, this person can be a job
foreman, a hired consultant, or someone who can represent the
building owner or contractor responsible for the removal. In
addition to the initial training requirement, a refresher training
course is required every 2 years. The NESHAP training requirements
became effective on November 20, 1991.
5.2. Asbestos training courses developed specifically to address
compliance with the NESHAP in roofing work, as well as courses
developed for other purposes can satisfy this requirement of the
NESHAP, as long as the course covers the areas specified in the
regulation. EPA believes that Asbestos Hazard Emergency Response Act
(AHERA) training courses will, for example, satisfy the NESHAP
training requirements. However, nothing in this interpretive rule or
in the NESHAP shall be deemed to require that roofing contractors or
roofing workers performing operations covered by the NESHAP must be
trained or accredited under AHERA, as amended by the Asbestos School
Hazard Abatement Reauthorization Act (ASHARA). Likewise, state or
local authorities may independently impose additional training,
licensing, or accreditation requirements on roofing contractors
performing operations covered by the NESHAP, but such additional
training, licensing or accreditation is not called for by this
interpretive rule or the federal NESHAP.
5.3. For removal of Category I asbestos containing roofing
material where RB roof cutters or equipment that similarly damages
the asbestos-containing roofing material are used, the NESHAP
training requirements (Sec. 61.145(c)(8)) apply as discussed in
Section I above. It is EPA's intention that removal of Category I
asbestos-containing roofing material using hatchets, axes, knives,
and/or the use of spud bars, pry bars and shovels to lift the
roofing material, or similar removal methods that slice, punch, or
shear the roof membrane are not subject to the training
requirements, since these methods do not cause the roof removal to
be subject to the NESHAP. Likewise, it is EPA's intention that roof
removal operations involving Category II nonfriable ACM are not
subject to the training requirements where such operations are not
subject to the NESHAP as discussed in section I above.
