adjustments may not exceed 5 percent
of the time the flare is receiving
regulated material.
(5) Recordkeeping Requirements
(a) All data must be recorded and
maintained for a minimum of 3 years or
for as long as required under applicable
rule subpart(s), whichever is longer.
(6) Reporting Requirements
(a) The information specified in
section III (6)(b) and (c) below must be
reported in the timeline specified by the
applicable rule subpart(s) for which the
flare will control emissions.
(b) Owners or operators shall include
the final AMEL operating requirements
for each flare in their initial Notification
of Compliance status report.
(c) The owner or operator shall notify
the Administrator of periods of excess
emissions in their Periodic Reports. The
notification shall include:
(i) Records of each 15-minute block
for all flares during which there was at
least 1 minute when regulated material
was routed to the flare and a complete
loss of pilot flame on a stage of burners
occurred, and for all flares, records of
each 15-minute block during which
there was at least 1 minute when
regulated material was routed to the
flare and a complete loss of pilot flame
on an individual burner occurred.
(ii) Records of visible emissions
events (including the time and date
stamp) that exceed more than 5 minutes
in any 2-hour consecutive period.
(iii) Records of each 15-minute block
period for which an applicable
combustion zone operating limit (i.e.,
NHVcz or LFLcz) is not met for the flare
when regulated material is being
combusted in the flare. Indicate the date
and time for each period, the NHVcz
and/or LFLcz operating parameter for the
period, the type of monitoring system
used to determine compliance with the
operating parameters (e.g., gas
chromatograph or calorimeter), and also

measurement, the stage(s) and number
of flare burners affected, and the range
of tested conditions or manufacturer’s
specifications.
(v) Records of when the staging valve
position indicator monitoring system
indicates a stage of the flare should not
be in operation and is or when a stage
of the flare should be in operation and
is not. Indicate the date and time for
each period, whether the stage was
supposed to be open, but was closed, or
vice versa, and the stage(s) and number
of flare burners affected.
IV. Request for Comments
We solicit comments on all aspects of
ExxonMobil’s, Marathon’s, Blanchard’s,

II. Background Information
A. Why are asbestos cement pipes being
replaced?
Drinking water, waste water, and
storm water are handled by a system of
pipes which deliver water to residences,
commercial, institutional, and industrial
users; transfer waste water from users to
wastewater treatment plants; and carry
untreated storm water to streams and
lakes. As the infrastructure of
municipalities age, utilities serving the
population need to replace deteriorated
water pipes. Existing water pipes can be
PO 00000
Frm 00052
Fmt 4703
Sfmt 4703
made of various components, such as
clay, iron, polyvinyl chloride (PVC),
concrete, and A/C. These A/C pipes are
potentially subject to regulation under
the Asbestos NESHAP when replaced.
When A/C pipes age, the cementitious
bonds in the pipe matrix weaken,
primarily due to the pH of the water,
particulate in suspension, acidic gases
in sewage, and the scrubbing effect of
sandy soil caused by movement, such as
tidal changes against the outside of the
pipe (e.g., in coastal environments).
These mechanisms degrade both the
outside and the inside of the pipes,
causing them to become compromised
and to leak.
Once pipes begin to leak, the
environment can be harmed in several
ways. Leaking waste water pipes can
pollute nearby waterways, such as
oceans, rivers, and lakes. Compromised
storm water pipes can allow excess
ground water, produced during high
volume storm events, to seep into the
E:\FR\FM\25APN1.SGM
25APN1
Federal Register / Vol. 83, No. 80 / Wednesday, April 25, 2018 / Notices
pipe through cracks. This influx of
ground water (or ‘‘infiltration’’) can
create a significant increase in the
volume of waste water arriving at waste
water treatment plants. If treatment
plants become overburdened, waste
water may be forced to be routed to the
nearest waterway without being
properly treated, leading to increased
waterway contamination. Compromised
drinking water pipes waste valuable
finished water, which can leak out of
the degraded pipes into surrounding
soils. Water pipes carrying finished
water have been known to rupture due
to a combination of degradation and a
high-pressure load, also known as a
water main break.
Because existing water pipes of all
types run beneath and beside major
roadways, beneath buildings, and
overlap other utilities (e.g., gas,
electricity, cable), their replacement can
potentially be problematic, especially in
high density residential, industrial, and
urban areas. Even replacement in
suburban and rural areas can require
careful navigation beneath roadways
and other major structures.

B. What is the Asbestos NESHAP?
The Asbestos NESHAP is a set of
work practice standards designed to
minimize the release of asbestos,
prescribed for the handling, processing,
and disposal of asbestos-containing
materials (ACM). The purpose of these
work practices is to minimize the
release of asbestos into the environment.
Asbestos is a known human
carcinogen and the primary route of
exposure is through inhalation of
asbestos fibers. The potential for
exposure to asbestos fibers is directly
linked to ACM’s potential to become
friable, and, thus, for fibers to become
airborne. Certain ACM can readily
release asbestos fibers when they are
disturbed or damaged. Asbestos fibers
can then become entrained into the
ambient air where they become
available for inhalation. More
information on the health effects of
asbestos may be found at https://
www.epa.gov/asbestos/learn-aboutasbestos#effects.
The Asbestos NESHAP defines friable
asbestos material as any material
containing more than 1-percent asbestos
as determined using the method
specified in 40 CFR part 763, subpart E,
appendix E, section 1, Polarized Light
Microscopy (PLM), that, when dry, can
be crumbled, pulverized, or reduced to
powder by hand pressure. If the asbestos
content is less than 10 percent, as
determined by a method other than
point counting by PLM, the asbestos
VerDate Sep<11>2014
19:12 Apr 24, 2018
Jkt 244001
content must be verified by point
counting using PLM.
In the preamble to the 1990 Asbestos
NESHAP amendments (55 FR 48406,
November 20, 1990), the EPA stated in
response to comments on the definition
of ‘‘friable’’ as it applied to the
demolition and renovation of ACM, that
the EPA’s intention was to distinguish
between materials that would readily
release asbestos fibers when damaged or
disturbed and those materials that were
unlikely to result in the release of
significant amounts of asbestos fibers.
The Asbestos NESHAP test to determine
if ACM is friable is to attempt to crush
the dry material by hand. If the dry
ACM can be crumbled, pulverized, or
crushed to powder by hand pressure, it
is friable, and is regulated under the
Asbestos NESHAP.
Asbestos-contaminated material
regulated under the Asbestos NESHAP
is termed regulated asbestos-containing
material (RACM). RACM is defined in
40 CFR 61.141 of the Asbestos NESHAP
and includes: (1) Friable 1 ACM; (2)
Category I nonfriable ACM 2 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 3 that has already
been or is likely to become crumbled,
pulverized, or reduced to powder by the
forces acting upon it. If the regulatory
threshold for RACM 4 is met or
exceeded in a renovation operation,
then all friable ACM in the operation,
and in certain situations, nonfriable
ACM in the operation, are subject to the
work practice standards of the Asbestos
NESHAP.
Thus, the purpose of the work
practices required for the removal of
A/C pipe in the Asbestos NESHAP is to
minimize the release of asbestos fibers
into the atmosphere, either at the time
the material is removed, or at a later
date, as a result of friable materials left
in the soil. Therefore, in evaluating
1 Friable ACM means any material containing
more than 1-percent asbestos as determined using
the method specified in 40 CFR part 763, subpart
E, appendix E, section 1, Polarized Light
Microscopy (PLM), that, when dry, can be
crumbled, pulverized, or reduced to powder by
hand pressure.
2 Category I nonfriable ACM means asbestoscontaining packings, gaskets, resilient floor
covering, and asphalt roofing products containing
more than 1-percent asbestos as determined using
PLM.
3 Category II nonfriable ACM means any material,
excluding Category I nonfriable ACM, containing
more than 1-percent asbestos as determined using
PLM, that, when dry, cannot be crumbled,
pulverized, or reduced to powder by hand pressure.
4 The regulatory threshold for RACM is 260 linear
feet, 160 square feet, or 35 cubic feet (if the amount
of RACM cannot otherwise be measured in linear
or square feet).

under 40 CFR 61.12(d) whether an AWP
will achieve a reduction in emissions of
asbestos fibers at least equivalent to the
reduction achieved under the Asbestos
NESHAP work practices, the EPA will
evaluate whether the AWP minimizes
the release of asbestos fibers to the
atmosphere.
C. How is an alternative work practice
approved?
The 40 CFR part 61 General
Provisions explain under what
circumstances the EPA may approve an
alternative means of emission
limitation. At 40 CFR 61.12(d)(1) and
(2), the General Provisions require that
the alternative means of emission
limitation must achieve a reduction in
emissions at least equivalent to the
reduction achieved by the work
practices required under the existing
standard, and that the Federal Register
document permitting the use of the
alternative be published only after
notice and an opportunity for a hearing.
Additionally, the Asbestos NESHAP
itself contains specific provisions under
which the EPA may receive applications
for prior written approval of an
alternative emission control and waste
treatment method. For example, 40 CFR
61.150(a)(4) authorizes ‘‘[u]se [of] an
alternative emission control and waste
treatment method that has received
prior approval by the Administrator
according to the procedure described in
40 CFR 61.149(c)(2).’’ As required by 40
CFR 61.150(a)(4) and 40 CFR
61.149(c)(2), before approval may be
granted for an AWP, a written
application must be submitted to the
Administrator demonstrating that the
following criteria are met: (i) The
alternative method will control asbestos
emissions equivalent to currently
required methods; (ii) the suitability of
the alternative method for the intended
application; (iii) the alternative method
will not violate other regulations; and
(iv) the alternative method will not
result in increased water pollution, land
pollution, or occupational hazards.
In order to be approved, the proposed
AWP must meet all requirements for no
visible emissions (VE), adequate
wetting, waste handling, and disposal
under the Asbestos NESHAP. The EPA
is proposing that this AWP is equivalent
to the work practice in the Asbestos
NESHAP: It removes A/C pipe while
replacing it with non-asbestos materials;
converts friable ACM, and ACM that
may become friable when disturbed into
nonfriable ACM during the replacement

sradovich on DSK3GMQ082PROD with NOTICES
process; and uses amended water 5 to
achieve adequate wetting of all ACM.
D. How do the Asbestos NESHAP
requirements apply to replacement of
A/C pipe?
To the extent A/C pipe is either
friable ACM or Category II nonfriable
ACM that has a high probability of
becoming or has become crumbled,
pulverized, or reduced to powder by the
forces expected to act on it during the
pipe replacement process, the A/C pipes
meet the RACM definition. If Category
II nonfriable A/C pipes do not have a
high probability of becoming and have
not become crumbled, pulverized, or
reduced to powder by the forces
expected to act on them during the pipe
replacement process, those pipes would
not be regulated as RACM under the
Asbestos NESHAP.
For renovations such as a regulated
underground ACPRP, if the total amount
of RACM for the project over the course
of a single calendar year to be stripped,
removed, dislodged, cut, drilled, or
similarly disturbed during the activity is
less than 260 linear feet, the renovation
work practices found in 40 CFR 61.145
of the NESHAP do not apply, regardless
of the pipe replacement method to be
used, the type of material (Category I or
II), or its condition (friable versus
nonfriable). See 40 CFR 61.145(a)(4).
The waste disposal requirements found
in 40 CFR 61.150 and 61.154 apply to
any source regulated under 40 CFR
61.145.
It is important to note that projects
may not be broken up to avoid
regulation under the Asbestos NESHAP,
and the EPA has clarified the
requirements of the Asbestos NESHAP
as they relate to a project on several
occasions. In our 1995 Clarification of
Intent, we stated the ‘‘EPA considers
demolitions planned at the same time or
as part of the same planning or
scheduling period to be part of the same
project. In the case of municipalities, a
scheduling period is often a calendar
year or fiscal year or the term of the
contract.’’ See 60 FR 38725 (July 28,
1995, Footnote 1). As stated in the 40
CFR part 61 General Provisions, ‘‘No
owner or operator shall build, erect,
install, or use any article, machine,
equipment, process, or method, the use
of which would otherwise constitute a
violation of an applicable standard.
Such concealment includes, but is not
limited to, the use of gaseous dilutants
to achieve compliance with a VE
standard, and the piecemeal carrying

chemicals (wetting agents) have been added to

out of an operation to avoid coverage by
a standard that applies only to
operations larger than a specified size.’’
As we said in addressing this issue in
a previous applicability determination,6
the relevant part of that requirement is
the part that discusses the prohibition
on the piecemeal carrying out of an
operation to avoid coverage by a
standard. Therefore, as required by 40
CFR 61.145(a)(iii) and (iv), owners or
operators (owner/operator) must predict
the combined additive amount of RACM
to be removed in the course of the
renovation activities (or, in the case of
emergency renovations, estimate that
amount) over the calendar year to
determine the applicability of the
standard to a project.
The work practices for asbestos
control under the Asbestos NESHAP
exist to minimize the release of asbestos
into the ambient air. When a facility
component that contains, is covered
with, or is coated with RACM is being
removed from a facility 7 as a unit or in
sections (e.g., a pipeline), the rule
requires adequate wetting of all RACM
exposed during cutting or disjoining
operations; and each unit or section to
be carefully lowered to the floor and/or
ground level, not dropping, throwing,
sliding, or otherwise damaging or
disturbing the RACM. After a facility
component (e.g., pipeline section)
containing, covered with, or coated with
RACM has been taken out of the facility
as a unit or in sections pursuant to
paragraph (c)(2), it shall be stripped or
contained in leak-tight wrapping.8 If
stripped, the owner/operator may either
adequately wet the RACM during
stripping; or use a local exhaust
ventilation and collection system
designed and operated to capture the
particulate asbestos material produced
by the stripping, and this system must
exhibit no VE to the outside air, or be
designed and operated in accordance
with 40 CFR 61.152 (air cleaning). For
removal of A/C pipe, the owner/
operator must ensure that no VE are
exhibited during the removal of the A/
C pipe and that all A/C pipe is kept
adequately wet to minimize the release
of asbestos emissions, unless one of the
other specific provisions of the Asbestos
NESHAP is followed. Additional

requirements apply to the waste
handling and disposal.
The work practices in the Asbestos
NESHAP that apply to the removal and
replacement of A/C pipe include
procedures for emission control,
handling of asbestos waste, and asbestos
waste disposal. These work practices are
discussed in the sections below.
1. Procedures for Emission Control
The principal controls in the Asbestos
NESHAP for renovations such as pipe
replacement operations include
requirements that the RACM be
adequately wetted to minimize VE
during pipe replacement operations
involving RACM, and that asbestos
waste be handled, collected, and
disposed of properly. The emission
control requirements must meet the
standard for no VE. ‘‘Adequately wet’’
means to sufficiently mix or penetrate
with liquid to prevent the release of
particulates. If VE are observed coming
from RACM, then that material has not
been adequately wetted. However, the
absence of VE is not sufficient evidence
of being adequately wet. Typically, the
emission controls used to achieve
adequate wetting include a fine water
spray (or a mist).9 The Asbestos
NESHAP (40 CFR 61.145(c)(6)) requires
that, after removal, the RACM must
remain adequately wet until collected
and contained, or treated in preparation
for disposal in accordance with 40 CFR
61.150.
The Asbestos NESHAP specifies at 40
CFR 61.150(a)(5) that the asbestoscontaining waste material (ACWM)
handling requirements do not apply to
Category I nonfriable ACM waste
(asbestos-containing packings, gaskets,
resilient floor covering, and asphalt
roofing products containing more than
1-percent asbestos) and Category II
nonfriable ACM waste (any other
nonfriable ACM containing more than 1percent asbestos) that did not become
crumbled, pulverized, or reduced to
powder.
2. Handling of Asbestos Waste
Asbestos containing waste materials
from activities regulated by 40 CFR
61.145 must be handled, collected, and
disposed of in accordance with 40 CFR
61.150. No VE may be discharged to the
outside air during the collection,
processing, packaging, or transportation
of any ACWM. All ACWM must be kept
adequately wet and sealed in leak-tight
9 While not required under the Asbestos
NESHAP, the EPA recommends the use of
surfactants to amend the water used to keep ACM
adequately wet because these water amendments
greatly enhance the ability of water to penetrate and
mix with ACM.

processed into a nonfriable form, such
as a nonfriable pellet or other shape (40
CFR 61.150(a)(2)).
sradovich on DSK3GMQ082PROD with NOTICES
3. Waste Disposal
The Asbestos NESHAP requires all
ACWM to be deposited as soon as is
practical in a waste disposal site
operated in accordance with the
provisions of 40 CFR 61.154 or an EPAapproved site that converts RACM and
ACWM into nonasbestos (asbestos-free)
material according to the provisions of
40 CFR 61.155.
E. What techniques are approved for
removal and replacement of A/C pipes?
Even A/C pipes in good condition
(which would be Category II nonfriable
ACM) become regulated ACM, if the
pipe has a high probability of becoming
or has become crumbled, pulverized, or
reduced to powder by the forces
expected to act on the pipe during the
renovation activities. Moreover, most of
the A/C pipe being replaced by
municipalities is likely to be in poor
condition (i.e., friable) due to the
degradation over time as discussed in
the section II of this document.
The EPA has previously determined 10
that pipe removal is generally a
renovation unless it is associated with
the demolition of a structure (in which
case, it is a demolition). One
applicability determination from 1994
states that removal of A/C pipe ‘‘. . . is
a renovation because the pipe is not a
load bearing structural member.’’
The accepted technique to remove
and replace A/C pipes is known as
‘‘open trench replacement.’’ In open
trench replacement, the pipe is located,
cleaned, and inspected. Because pipes
run beneath and cross transportation
corridors, traffic is rerouted to available
detours. Temporary water and sewer
service is installed to handle the water
supply and/or wastewater handling
affected by the disruption of service.
Other utilities (electricity, cable, optical
fiber) that may obstruct or interfere with
pipe replacement are also identified.
Once the location of the pipe and all
utilities are identified, the road
surfacing, and other structures, such as
sidewalks, medians, etc., are removed
and an open trench is dug to expose the
length of pipe to be replaced. A pipe
cutter is clamped around the A/C pipe
being replaced, and it is scored along
the outside of its circumference while
water is applied to prevent emissions of
asbestos to the atmosphere, which may

occur along the line of cutting. The pipe
is snapped along the cut and the process
is repeated to produce transportable 6to 8-foot sections of pipe. Asbestos
cement pipe in poor condition may
resemble wet cardboard in the way it
responds to these removal activities. It
can simply collapse and tear into
smaller pieces, rather than snap, as
A/C pipe in good condition is known to
do. Each pipe section is removed,
wrapped in plastic, and placed on a
truck labelled according to regulations
for asbestos waste disposal. This process
of snap cutting and removal is repeated
for the entire length of A/C pipe to be
replaced.
No AWPs for the replacement of A/C
pipes have yet been approved.
III. Alternative Work Practice Request
A. What is the close tolerance pipe
slurrification technique for A/C pipe
replacement?
The EPA received a request from
Trenchless Consulting, LLC, in July
2017, for approval of an AWP, known as
the ‘‘Close Tolerance Pipe
Slurrification’’ (CTPS) method, for the
removal and replacement of A/C pipes.
This is one of two AWPs requested. The
second one, which involves a technique
commonly known as ‘‘pipe bursting’’ is
still under consideration. We are not
discussing ‘‘pipe bursting’’ in this
Federal Register document and no
decision has been made on whether or
not to propose approval of ‘‘pipe
bursting’’ as an AWP.
Documentation for CTPS is found in
the Docket, and includes photographs
and video of the CTPS process
demonstration on clay pipe,11
schematics of the process, and
descriptions of the process. The CTPS
method uses an equipment train to
deliver drilling fluids and clays in
suspension through a pipe in the center
of the train. The equipment train uses a
cutting head which grinds the
underground A/C pipe to a fine grain
while the fluids maintain the adequately
wet requirements of 40 CFR 61.145 and
entrain the finely ground pipe fragments
in a slurry. During this process, the
slurry mixes with the drilling fluids to
create a homogenous 12 wet
cementitious material, which is
removed from the underground pipe
path at vertical access points (i.e.,
manholes, trenches, other vertical
11 According to the demonstration of the CTPS
process by Portland Utilities, clay pipe is
pulverized and slurrifies similarly to A/C pipe
when subjected to the CTPS process.
12 A homogenous mixture is one in which the
components are uniformly distributed throughout
the mixture.

18047
access cuts). These vertical access
points are sheathed with a
nonpermeable lining, such as plastic, at
the beginning and end of the run of pipe
being replaced. The cementitious slurry
hardens into a nonfriable A/C after 48–
56 hours. The proposed CTPS AWP
employs dust suppression using
amended water at all vertical access
points to maintain the no VE and
adequately wet requirements of the
Asbestos NESHAP, as required by 40
CFR 61.145 and 40 CFR 61.150.
The EPA is proposing to consider the
slurry that is formed by the CTPS AWP
for A/C pipe to be nonfriable once
hardened. This is important because the
typical A/C pipe that is replaced is
usually friable in many places and in
poor condition. The proposed CTPS
AWP converts all the ACM of the A/C
pipe into a nonfriable material which is
disposed of in a landfill permitted to
receive ACWM. A skim coat of the
nonfriable cementitious ACM remains
on the outer rim of the new pipe.
Because disposal takes place before
the slurry hardens, and the test to
determine friability takes place after the
slurry hardens, the slurry must be
sealed in containment at disposal
(rather than disposed openly pending
the outcome of the test). Although the
Asbestos NESHAP does not require
containment of nonfriable ACM, this
AWP must ensure the ACWM is
contained because the test indicating
the ACWM is nonfriable would not yet
have been conducted at the time of
disposal (the friability test is done on a
sample of the material that has cured
and hardened over a period of 48 to 56
hours).
In contrast to the Asbestos NESHAP
work practices for ACPRPs conducted in
temperatures below freezing, the CTPS
method may only be used when
temperatures are above 32 °F (0 °C) to
prevent freezing the slurry, drilling
fluids, and/or the amended water
needed to maintain adequate wetting.
B. What is the EPA’s proposed action on
the AWP request?
The EPA believes that the CTPS work
practices are ‘‘consistent with the EPA’s
intent to distinguish between material
that could release significant amounts of
asbestos fibers during demolition and
renovation operations and those that
would not, and to prevent significant
emissions of asbestos fibers to the
atmosphere.’’ (see 55 FR 48408,
November 20, 1990 Asbestos NESHAP
final notice, in our statements in
response to comments on friable vs.
nonfriable materials). The EPA is
proposing that, for the following five
reasons, CTPS is at least equivalent to
E:\FR\FM\25APN1.SGM
25APN1
sradovich on DSK3GMQ082PROD with NOTICES
18048
Federal Register / Vol. 83, No. 80 / Wednesday, April 25, 2018 / Notices
the Asbestos NESHAP process for A/C
pipe removal.
First, this technique of replacement
only exposes a small portion of the
A/C pipe, thereby preventing significant
emissions of asbestos to the atmosphere,
a part of the overall reduction in
emissions potential. As described in
more detail below, the CTPS approach
only excavates the A/C pipe at
predetermined points along the pipe’s
path. Vertical access cuts are made to
remove A/C pipe only at the beginning
and end of the length of pipe to be
removed and in designated vertical
access points to reduce pressure
buildup of the slurry. This limited
excavation reduces the level of exposure
to asbestos emissions from the A/C pipe
remediation project.
Second, during periods where ACM is
exposed, it is in the liquid slurry form
and is considered adequately wet and,
thus, does not become airborne, where
it could be available for inhalation. The
slurry is pumped out of these points
into an enclosed tank to be taken to a
waste disposal site approved to receive
asbestos.
Third, the CTPS AWP uses amended
water to improve dust suppression at all
cuts, trenches, and vertical access points
where A/C pipe may be exposed to the
ambient air. The pipe is otherwise not
exposed to the air.
Fourth, a skim coat of slurry, which
contains ACM and remains on the new
pipe, is not loose in the soil, but adheres
to the surface of the new pipe. The skim
coat fills the annular space created by
the close tolerance drill through the
ground as it pulls the new pipe through.
Therefore, it has a structural support
preventing the thin coating from being
crushed, and also is not free to migrate
to the surface as a result of soil
movement, such as frost heaves.13
Furthermore, the existence of asbestos
in the skim coat is noted on the utility
records so that owners/operators are
advised of its presence.
Fifth, once hardened, the skim coat is
nonfriable and has properties of cement:
Similar to light-weight flowable fill
(concrete) purchased from concrete
plants, the skim coat has a strength of
50–150 pounds per square inch. Once
hardened, the skim coat has static
properties such that it does not settle or
compress further. Once the skim coat is
in place, it can only be removed by
force, i.e., using a pipe saw or a pipe
13 Frost heaves occur in the top 3 feet of soil, and
occur at low temperatures when available moisture
in the soil freezes, expanding, and displaces
materials with higher surface area (regardless of
density) upward due to decreasing pressure. In this
way, chunks of material of various densities may be
moved to the surface.

cutter. Additionally, the skim coat is not
subject to corrosional forces from inside
the pipe. For more information on the
properties of the skim coat that remains
on the pipe, see docket item ‘‘Skim Coat
Properties, email correspondence from
Mike Woodcock, Portland Utilities
Construction, January 2018.’’
The Asbestos NESHAP focuses on
asbestos containing materials and their
decline into friable material. Since the
advent of new methods which were not
available at the time of the last
amendment to the rule, this may be a
procedure whereby friable A/C pipe in
poor condition is partially remediated
back to a nonfriable state, and its
properties are similar to the properties
of other cement products such as
flowable fill concrete.
Close tolerance pipe slurrification
differs from the conventional work
practices in which the entire pipe, much
of which is in poor condition and may
be friable, is excavated and exposed, cut
into numerous 6- to 8-foot transportable
sections, sealed in leak-tight wrapping,
labeled, and transported to an approved
asbestos waste disposal site. Five A/C
pipe replacement guidance documents
from state and local agencies (from
Massachusetts, Maine, Oregon, Utah,
and the city of Richmond, Virginia) are
available in the docket for reference on
the conventional work practices.
Consequently, the EPA believes that
by following the CTPS AWP, adequately
wet and no VE protocols, and exposing
only small sections of A/C pipe to the
air, asbestos emissions to the
atmosphere are minimized, and the
AWP would achieve an emission
reduction at least equivalent to the
current Asbestos NESHAP.
While the Asbestos NESHAP (and
associated applicability determinations)
contemplate and provide direction on a
number of situations for handling and
managing asbestos, the situation
whereby friable ACM is turned into
nonfriable ACM is not one that is
contemplated under the rule. The EPA
is proposing that when the CTPS work
practices are adhered to as described in
this document, and when the test for
friability confirms that the resulting
hardened slurry (skim coating) is
nonfriable ACM, the resulting material
can be regulated as nonfriable ACM.
Under 40 CFR 61.145(c)(1)(iv) of the
Asbestos NESHAP, under certain
conditions nonfriable ACM need not be
removed, if they are Category II
nonfriable ACM and the probability is
low that materials will become
crumbled, pulverized, or reduced to
powder during demolition. We are
proposing that the nonfriable skim
coating of ACM left on the outer rim of
PO 00000
Frm 00056
Fmt 4703
Sfmt 4703
the new pipe be allowed to also remain
in place.
The EPA is proposing that when
CTPS is used to remove the
underground A/C pipe, while
maintaining no VE and the adequately
wet requirements of 40 CFR 61.145 and
40 CFR 61.150(a), removing the old
A/C pipe, converting all A/C pipe to
Category II nonfriable ACM, and
replacing the underground A/C pipe
with new pipe, then CTPS is at least
equivalent, in terms of emission
reductions, to the work practices in the
Asbestos NESHAP as they apply to
renovations.
The Asbestos NESHAP waste disposal
requirements include deed notations for
inactive asbestos waste disposal sites,
where ACWM (e.g., friable ACM) has
been left behind in the ground. The EPA
included this provision in the Asbestos
NESHAP for situations in which
manufacturing waste had been left
behind, sometimes buried on property,
and that property later was sold for
development. Without a deed notation
to warn potential buyers of its presence,
new owners could accidentally expose
themselves to asbestos (for example, by
installing a swimming pool, driveway,
or digging a basement). The EPA,
therefore, added requirements for
property deed notation when ACWM
has been left behind in the ground,
creating an inactive asbestos waste
disposal site.
The EPA is proposing that the
nonfriable ACM resulting from CTPS
would not be subject to deed notations.
However, as is current practice, the EPA
proposes that owner/operators (e.g.,
municipality or utility) using the CTPS
AWP would be required to maintain
utility maps with the actual location of
each ACPRP identified by the 6-digit
latitude and longitude coordinates of
the newly laid line, and that the utility
maps would note the line as covered by
a skim coat of ACM for future work.
The EPA is also proposing that the
other requirements in the Asbestos
NESHAP that apply to renovations,
including notification requirements
found in 40 CFR 61.145(b), would apply
to the CTPS AWPs. Additionally, the
EPA is proposing that the waste
handling and disposal requirements
found in 40 CFR 61.150 and 61.154
would apply to the slurry that is
removed at the ACPRP.
IV. What are the proposed work
practices for A/C pipe replacement?
The EPA is seeking the public’s input
on Trenchless Consulting’s request that
the EPA approve the CTPS approach as
an AWP under the Asbestos NESHAP.
We are seeking comments on whether
E:\FR\FM\25APN1.SGM
25APN1
Federal Register / Vol. 83, No. 80 / Wednesday, April 25, 2018 / Notices
sradovich on DSK3GMQ082PROD with NOTICES
the CTPS work practices are equivalent
to those in the Asbestos NESHAP,
including adequate wetting
requirements, no VE, notification,
containment, labeling, waste handling,
waste transportation, and disposal of
ACWM. The materials supporting the
request for this approval are available in
the Docket and include industry
descriptions of the CTPS work practice
and processes, the process patent,
records of the EPA’s communication
with the industry requestors, and the
EPA’s observations of the methods
conducted on PVC and clay sewer pipe.
Based upon our initial review of the
proposed AWP request, the
demonstrations of the work practice,
and written materials including
equipment, materials, slurry
characteristics, testing, and waste
specifications, we propose that, by
complying with the following list of
requirements, this proposed AWP will
achieve emission reductions at least
equivalent to emission reductions
achieved under 40 CFR 61.145, 40 CFR
61.150, and 40 CFR 61.154, as required
by the applicable Asbestos NESHAP,
provided that adequate wetting
accompanies all vertical access points,
access trenches, and manholes to
prevent VE, and that the A/C
cementitious material resulting from
this process is properly handled and
contained during and after removal and
properly disposed of as required by the
Asbestos NESHAP.
The patent related to this process,
‘‘Method of Replacing an Underground
Pipe Section,’’ is available from the U.S.
Patent Office, patent number
US8,641,326B2; February 4, 2014, and a
copy is available in the docket. That
patent deals with the replacement of
low-pressure sewer pipes and indicates
some parameters that may be different
from the work practices in this notice,
depending on the soil composition,
depth of pipe, and serviceable use of the
pipe (e.g., a low-pressure sewer, waste
water, or fresh water pipe). While this
patented process is one used by the
company requesting approval of this
AWP, an owner/operator would not
have to license the patent and could
choose different equipment in order to
follow the work practices of this notice.
A. What is the proposed CTPS AWP?
The proposed CTPS AWP is as
follows:
1. Vertical Access Points
Vertical access points (e.g., manholes,
trenches) are made at designated
intervals along the length of pipe
replacement. The distance between
vertical access points is a function of the
VerDate Sep<11>2014
19:12 Apr 24, 2018
Jkt 244001
soil type, pipe size, pneumatic pressure
on the CTPS head, and frictional drag
on the line; and is determined for each
project on a case-by-case basis by the
owner/operator. Incorrect estimation of
the vertical access point locations may
result in a malfunction. The owner/
operator must not disturb A/C pipe
during the digging out of these access
points. Water and suction should be
used to uncover as much of the A/C
pipe as is needed to begin the CTPS
process.
2. Removal of Pipe at Terminals and
Vertical Access Points
At the starting and terminal points,
and at designated intervals along the
length of pipe replacement, sections of
pipe are cut and removed at the vertical
access points (i.e., manholes, trenches).
The owner/operator must handle all
sections of A/C pipe in accordance with
40 CFR 61.145 and 40 CFR 61.150 of the
Asbestos NESHAP.
3. CTPS Equipment Train
The CTPS technique should use a
drilling head train with a slightly larger
diameter than the pipe being replaced.
This technology must use a heavy duty
four-stage cutting and wetting train,
made of hardened carbon steel, which is
able to be fed directly around the pipe
to be replaced. The cutting head must be
drawn around the existing pipe and
must be capable of grinding the old
A/C pipe to a fine powder using a liquid
delivery system as described in section
IV.A.4 of this preamble. The process
must return the A/C pipe to a
cementitious slurry that is a
homogenous mixture and stays
adequately wet through disposal
according to the requirements of 40 CFR
61.145. The owner/operator must ensure
that the CTPS train pulls the
replacement pipe behind it, and that no
ACM contacts the inside of the new
pipe.
4. Liquid Delivery
The horizontal drilling train must be
equipped with ports to deliver liquid
materials to the drilling head. Drilling
fluids and bentonite clay should also be
delivered through these ports to reduce
frictional drag on the line, and to
lubricate the interface along the soil to
pipe line.
5. Trackable Pipeline
The owner/operator would be
required to ensure that the new pipeline
is trackable by steel cable (or other
durable trackable material) laid with the
new pipe.

6. Slurry Characteristics
The owner/operator would be
required to ensure that no visible
emissions are discharged to the air from
the slurry, and that the slurry is a
homogenous mixture comprised of
finely ground A/C pipe, drilling fluids,
bentonite clay, and other materials
suspended in solution that, when cured
(a period of 48–56 hours), re-hardens so
that it meets the sample friability test in
section IV.D.2 of this preamble. The
slurry must meet the no visible
emissions requirements of 40 CFR
61.145 and 61.150.
7. Slurry Removal, Containment,
Transportation, and Disposal
The A/C pipe slurry is removed at
vertical access points using a vacuum
attached to a tank (e.g., vacuum truck).
The owner/operator would be required
to ensure that the slurry remains in an
adequately wet state during the
slurrification process and remains in
containment throughout the removal,
transportation, and disposal processes,
meeting the requirements of 40 CFR
61.145 and 40 CFR 61.150. The slurry
must be contained and in slurry form at
the time of disposal in a landfill
permitted to accept ACWM and meeting
the requirements of 40 CFR 61.154. The
slurry must be managed at the disposal
site using procedures meeting the
requirements of 40 CFR 61.154.
8. Adequate Wetting With No VE
Any opening to the atmosphere along
the pipe is a potential source of asbestos
emissions to the outside (ambient) air.
The owner/operator would be required
to ensure that dust suppression
equipment (i.e., dust suppression
apparatus or manual misting) using
amended water is placed at each vertical
access point. If a new trench is dug to
resolve a malfunction, the owner/
operator would be required to ensure
that the new trench is equipped with
dust suppression and follow the
procedure in paragraphs (1) and (2)
above. Amended water is water to
which surfactant chemicals (wetting
agents) have been added to reduce the
surface tension of the water.
B. What notification requirements
would apply?
If an underground ACPRP meets the
applicability and threshold
requirements under the NESHAP, then
the EPA (or the delegated agency) must
be notified in advance of the
replacement in accordance with the
requirements of the Asbestos NESHAP
at 40 CFR 61.145(b). See 40 CFR 61.145
for more information on the notification
requirements.

Federal Register / Vol. 83, No. 80 / Wednesday, April 25, 2018 / Notices
C. What inspection, operation, and
maintenance requirements would
apply?
1. Inspection
Prior to using the CTPS for an ACPRP,
the owner/operator would conduct
underground pipe inspections (e.g., by
using remote technologies like robotic
cameras) and shall identify, locate, and
mark onto an underground utility map
of the area all identified potential areas
of malfunctions, such as changes in pipe
type, drops in the line, broken and offcenter points, and changes in soil type.
2. Operation and Maintenance
The owner/operator of a CTPS
method system is required to install,
operate, and maintain the drilling head
train, CTPS liquid delivery system, and
all equipment used to deliver adequate
wetting at all vertical access points and
cut lengths of pipe in accordance with
their written standard operating
procedures. The records must be kept in
accordance with section IV.F.1 of this
preamble.
D. What sampling, testing, and utility
map notation requirements would
apply?
3. Utility Map Notations
1. Sample Collection
After the slurry has been pumped
from the vertical access points, but
before disposal, the owner/operator of a
CTPS method system is required to
collect a 2-inch roughly spherical wet
sample of the slurry. A single sample
must be collected for each project
discharging to a single enclosed tank.
The owner/operator would be required
to seal the sample in leak-tight
wrapping and allow the sample to
harden and dry (usually 48–56 hours).
sradovich on DSK3GMQ082PROD with NOTICES
2. Sample Friability Test and
Certification
When the sample is hardened and
dry, the owner/operator would be
required to attempt to crush the sample
by hand. The sample that cannot be
crumbled, pulverized, or reduced to
powder by hand pressure is nonfriable,
and the remaining slurry from that pipe
replacement job is likewise nonfriable.
After testing, the owner/operator would
be required to ensure that the sample is
packaged in leak-tight wrapping for
storage, labeled ‘‘Asbestos Containing
Material. Do not break or damage this
sealed package,’’ dated according to the
ACPRP date of generation, stored in a
secure location that is inaccessible to
the general public (such as a locked
storage unit), and is maintained by the
owner/operator for a period of 2 years.
After this 2-year retention period, the
VerDate Sep<11>2014
19:12 Apr 24, 2018
Jkt 244001
sample may be disposed of in a landfill
permitted to accept ACWM.
a. If the sample cannot be crushed,
crumbled, or reduced to powder by
hand pressure, the owner/operator
would be required to certify this as
follows: ‘‘The hardened slurry sample
from the ACPRP conducted on (date) at
(location) could not be crushed,
crumbled, or reduced to powder by
hand pressure. I am aware it is unlawful
to knowingly submit incomplete, false,
and/or misleading information and
there are significant criminal penalties
for such unlawful conduct, including
the possibility of fine and
imprisonment.’’ The owner/operator
would be required to maintain a signed
certificate of this statement so that it is
available to the EPA Administrator,
local, and state agency officials upon
demand.
b. If the sample can be crushed,
crumbled, or reduced to powder by
hand pressure, the owner/operator
would be required to follow the
malfunction reporting requirements in
IV.F. 2 below.
Owner/operators would be required to
note utility maps according to the actual
location identified by the 6-digit
latitude and longitude coordinates of
the newly laid line. Notations would
have to be maintained for the life of the
new pipe by the owner/operator (e.g.,
municipality or utility), and would have
to be labeled as covered by a skim coat
of ACM for future work.
E. What labeling and transportation
requirements would apply?
Because all A/C pipe being replaced
using the CTPS technique is converted
to a nonfriable state during the
replacement, it would be categorized as
Category II ACM and would need to be
labeled and transported in accordance
with the corresponding requirements of
40 CFR 61.145 and 40 CFR 61.150 in the
Asbestos NESHAP.
F. What recordkeeping and reporting
requirements would apply?
1. The owner/operator would be
required to record and maintain for a
period of 2 years the following data:
a. Date(s) from beginning to end of
each ACPRP;
b. Location(s) of the A/C pipe(s)
replaced using CTPS, identified by 6digit latitudinal and longitudinal
coordinates for each ACPRP;
c. Diameter and length of A/C pipe
replaced at the ACPRP;
d. Total amount of slurry generated at
the ACPRP;
PO 00000
Frm 00058

Sfmt 4703
e. Total amount of slurry disposed by
the owner/operator from the ACPRP;
f. Slurry disposal site;
g. Manifest of ACM slurry disposal;
and
h. Malfunction records (if applicable).
i. Records of VE events and their
duration (including the time and date
stamp) of any VE event;
ii. Records of when and how each VE
event was resolved. Indicate the date
and time for each VE period, whether
the VE event occurred at an exposed
manhole, trench, or other vertical access
point, and the number of openings to
the ambient air affected;
iii. Procedure used to resolve each VE
event; and
iv. Results of each sample friability
test that indicates the slurry is friable,
as required by IV.D.1 and 2 above.
i. Records of the standard operation
procedures for the installation,
operation, and maintenance of the
drilling head train, CTPS liquid delivery
system, and all equipment used to
deliver adequate wetting at all vertical
access points and cut lengths of pipe.
2. Each owner/operator is required to
submit the following reports to the
Administrator after each occurrence, as
follows:
a. Malfunction Report. The
malfunction report must include the
records in section IV.F.1.h.i.-iv of this
preamble. The malfunction report must
be submitted as soon as practical after
the occurrence, but in no case later than
30 days.
b. ACPRP Report. The ACPRP report
must be submitted to the Asbestos
NESHAP program office within the EPA
Regional office in which the ACPRP is
located. The report may be submitted
electronically when the means to do so
are available. The EPA Regional office
may, at their discretion, waive this
requirement and delegate this reporting
to the state and municipality. If the EPA
Regional office has waived the
reporting, and if the state or
municipality is unable to receive
electronic reports, then only a hard copy
is required to be submitted. These
reports must be postmarked or
electronically submitted within 30
calendar days of completion of the
ACPRP.
V. Request for Comments
We solicit comments on all aspects of
this request for approval of CTPS as an
AWP for the work practice standards
specified in 40 CFR part 61, subpart M,
the Asbestos NESHAP. We specifically
seek comments regarding whether the
AWPs, as described in section IV above,
will achieve emission reductions at least
equivalent to the work practices in the

II. Background Information
A. Why are asbestos cement pipes being replaced?
Drinking water, waste water, and storm water are handled by a
system of pipes which deliver water to residences, commercial,
institutional, and industrial users; transfer waste water from users to
wastewater treatment plants; and carry untreated storm water to streams
and lakes. As the infrastructure of municipalities age, utilities
serving the population need to replace deteriorated water pipes.
Existing water pipes can be made of various components, such as clay,
iron, polyvinyl chloride (PVC), concrete, and A/C. These A/C pipes are
potentially subject to regulation under the Asbestos NESHAP when
replaced.
When A/C pipes age, the cementitious bonds in the pipe matrix
weaken, primarily due to the pH of the water, particulate in
suspension, acidic gases in sewage, and the scrubbing effect of sandy
soil caused by movement, such as tidal changes against the outside of
the pipe (e.g., in coastal environments). These mechanisms degrade both
the outside and the inside of the pipes, causing them to become
compromised and to leak.
Once pipes begin to leak, the environment can be harmed in several
ways. Leaking waste water pipes can pollute nearby waterways, such as
oceans, rivers, and lakes. Compromised storm water pipes can allow
excess ground water, produced during high volume storm events, to seep
into the
[[Page 18045]]
pipe through cracks. This influx of ground water (or ``infiltration'')
can create a significant increase in the volume of waste water arriving
at waste water treatment plants. If treatment plants become
overburdened, waste water may be forced to be routed to the nearest
waterway without being properly treated, leading to increased waterway
contamination. Compromised drinking water pipes waste valuable finished
water, which can leak out of the degraded pipes into surrounding soils.
Water pipes carrying finished water have been known to rupture due to a
combination of degradation and a high-pressure load, also known as a
water main break.
Because existing water pipes of all types run beneath and beside
major roadways, beneath buildings, and overlap other utilities (e.g.,
gas, electricity, cable), their replacement can potentially be
problematic, especially in high density residential, industrial, and
urban areas. Even replacement in suburban and rural areas can require
careful navigation beneath roadways and other major structures.
B. What is the Asbestos NESHAP?
The Asbestos NESHAP is a set of work practice standards designed to
minimize the release of asbestos, prescribed for the handling,
processing, and disposal of asbestos-containing materials (ACM). The
purpose of these work practices is to minimize the release of asbestos
into the environment.
Asbestos is a known human carcinogen and the primary route of
exposure is through inhalation of asbestos fibers. The potential for
exposure to asbestos fibers is directly linked to ACM's potential to
become friable, and, thus, for fibers to become airborne. Certain ACM
can readily release asbestos fibers when they are disturbed or damaged.
Asbestos fibers can then become entrained into the ambient air where
they become available for inhalation. More information on the health
effects of asbestos may be found at https://www.epa.gov/asbestos/learn-about-asbestos#effects.
The Asbestos NESHAP defines friable asbestos material as any
material containing more than 1-percent asbestos as determined using
the method specified in 40 CFR part 763, subpart E, appendix E, section
1, Polarized Light Microscopy (PLM), that, when dry, can be crumbled,
pulverized, or reduced to powder by hand pressure. If the asbestos
content is less than 10 percent, as determined by a method other than
point counting by PLM, the asbestos content must be verified by point
counting using PLM.
In the preamble to the 1990 Asbestos NESHAP amendments (55 FR
48406, November 20, 1990), the EPA stated in response to comments on
the definition of ``friable'' as it applied to the demolition and
renovation of ACM, that the EPA's intention was to distinguish between
materials that would readily release asbestos fibers when damaged or
disturbed and those materials that were unlikely to result in the
release of significant amounts of asbestos fibers. The Asbestos NESHAP
test to determine if ACM is friable is to attempt to crush the dry
material by hand. If the dry ACM can be crumbled, pulverized, or
crushed to powder by hand pressure, it is friable, and is regulated
under the Asbestos NESHAP.
Asbestos-contaminated material regulated under the Asbestos NESHAP
is termed regulated asbestos-containing material (RACM). RACM is
defined in 40 CFR 61.141 of the Asbestos NESHAP and includes: (1)
Friable \1\ ACM; (2) Category I nonfriable ACM \2\ 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 \3\ that has
already been or is likely to become crumbled, pulverized, or reduced to
powder by the forces acting upon it. If the regulatory threshold for
RACM \4\ is met or exceeded in a renovation operation, then all friable
ACM in the operation, and in certain situations, nonfriable ACM in the
operation, are subject to the work practice standards of the Asbestos
NESHAP.
---------------------------------------------------------------------------
\1\ Friable ACM means any material containing more than 1-
percent asbestos as determined using the method specified in 40 CFR
part 763, subpart E, appendix E, section 1, Polarized Light
Microscopy (PLM), that, when dry, can be crumbled, pulverized, or
reduced to powder by hand pressure.
\2\ Category I nonfriable ACM means asbestos-containing
packings, gaskets, resilient floor covering, and asphalt roofing
products containing more than 1-percent asbestos as determined using
PLM.
\3\ Category II nonfriable ACM means any material, excluding
Category I nonfriable ACM, containing more than 1-percent asbestos
as determined using PLM, that, when dry, cannot be crumbled,
pulverized, or reduced to powder by hand pressure.
\4\ The regulatory threshold for RACM is 260 linear feet, 160
square feet, or 35 cubic feet (if the amount of RACM cannot
otherwise be measured in linear or square feet).
---------------------------------------------------------------------------
Thus, the purpose of the work practices required for the removal of
A/C pipe in the Asbestos NESHAP is to minimize the release of asbestos
fibers into the atmosphere, either at the time the material is removed,
or at a later date, as a result of friable materials left in the soil.
Therefore, in evaluating under 40 CFR 61.12(d) whether an AWP will
achieve a reduction in emissions of asbestos fibers at least equivalent
to the reduction achieved under the Asbestos NESHAP work practices, the
EPA will evaluate whether the AWP minimizes the release of asbestos
fibers to the atmosphere.
C. How is an alternative work practice approved?
The 40 CFR part 61 General Provisions explain under what
circumstances the EPA may approve an alternative means of emission
limitation. At 40 CFR 61.12(d)(1) and (2), the General Provisions
require that the alternative means of emission limitation must achieve
a reduction in emissions at least equivalent to the reduction achieved
by the work practices required under the existing standard, and that
the Federal Register document permitting the use of the alternative be
published only after notice and an opportunity for a hearing.
Additionally, the Asbestos NESHAP itself contains specific
provisions under which the EPA may receive applications for prior
written approval of an alternative emission control and waste treatment
method. For example, 40 CFR 61.150(a)(4) authorizes ``[u]se [of] an
alternative emission control and waste treatment method that has
received prior approval by the Administrator according to the procedure
described in 40 CFR 61.149(c)(2).'' As required by 40 CFR 61.150(a)(4)
and 40 CFR 61.149(c)(2), before approval may be granted for an AWP, a
written application must be submitted to the Administrator
demonstrating that the following criteria are met: (i) The alternative
method will control asbestos emissions equivalent to currently required
methods; (ii) the suitability of the alternative method for the
intended application; (iii) the alternative method will not violate
other regulations; and (iv) the alternative method will not result in
increased water pollution, land pollution, or occupational hazards.
In order to be approved, the proposed AWP must meet all
requirements for no visible emissions (VE), adequate wetting, waste
handling, and disposal under the Asbestos NESHAP. The EPA is proposing
that this AWP is equivalent to the work practice in the Asbestos
NESHAP: It removes A/C pipe while replacing it with non-asbestos
materials; converts friable ACM, and ACM that may become friable when
disturbed into nonfriable ACM during the replacement
[[Page 18046]]
process; and uses amended water \5\ to achieve adequate wetting of all
ACM.
---------------------------------------------------------------------------
\5\ Amended water is water to which surfactant chemicals
(wetting agents) have been added to reduce the surface tension of
the water.
---------------------------------------------------------------------------
D. How do the Asbestos NESHAP requirements apply to replacement of A/C
pipe?
To the extent A/C pipe is either friable ACM or Category II
nonfriable ACM that has a high probability of becoming or has become
crumbled, pulverized, or reduced to powder by the forces expected to
act on it during the pipe replacement process, the A/C pipes meet the
RACM definition. If Category II nonfriable A/C pipes do not have a high
probability of becoming and have not become crumbled, pulverized, or
reduced to powder by the forces expected to act on them during the pipe
replacement process, those pipes would not be regulated as RACM under
the Asbestos NESHAP.
For renovations such as a regulated underground ACPRP, if the total
amount of RACM for the project over the course of a single calendar
year to be stripped, removed, dislodged, cut, drilled, or similarly
disturbed during the activity is less than 260 linear feet, the
renovation work practices found in 40 CFR 61.145 of the NESHAP do not
apply, regardless of the pipe replacement method to be used, the type
of material (Category I or II), or its condition (friable versus
nonfriable). See 40 CFR 61.145(a)(4). The waste disposal requirements
found in 40 CFR 61.150 and 61.154 apply to any source regulated under
40 CFR 61.145.
It is important to note that projects may not be broken up to avoid
regulation under the Asbestos NESHAP, and the EPA has clarified the
requirements of the Asbestos NESHAP as they relate to a project on
several occasions. In our 1995 Clarification of Intent, we stated the
``EPA considers demolitions planned at the same time or as part of the
same planning or scheduling period to be part of the same project. In
the case of municipalities, a scheduling period is often a calendar
year or fiscal year or the term of the contract.'' See 60 FR 38725
(July 28, 1995, Footnote 1). As stated in the 40 CFR part 61 General
Provisions, ``No owner or operator shall build, erect, install, or use
any article, machine, equipment, process, or method, the use of which
would otherwise constitute a violation of an applicable standard. Such
concealment includes, but is not limited to, the use of gaseous
dilutants to achieve compliance with a VE standard, and the piecemeal
carrying out of an operation to avoid coverage by a standard that
applies only to operations larger than a specified size.'' As we said
in addressing this issue in a previous applicability determination,\6\
the relevant part of that requirement is the part that discusses the
prohibition on the piecemeal carrying out of an operation to avoid
coverage by a standard. Therefore, as required by 40 CFR 61.145(a)(iii)
and (iv), owners or operators (owner/operator) must predict the
combined additive amount of RACM to be removed in the course of the
renovation activities (or, in the case of emergency renovations,
estimate that amount) over the calendar year to determine the
applicability of the standard to a project.
---------------------------------------------------------------------------
\6\ Applicability Determination Number A020001. August 30, 2002.
From George Czerniak, Chief, Air Enforcement and Compliance
Assurance Branch, U.S. EPA Region 5, to Robert Swift. https://cfpub.epa.gov/adi/index.cfm?fuseaction=home.dsp_show_file_contents&CFID=27301905&CFTOKEN=85118624&id=A020001.
---------------------------------------------------------------------------
The work practices for asbestos control under the Asbestos NESHAP
exist to minimize the release of asbestos into the ambient air. When a
facility component that contains, is covered with, or is coated with
RACM is being removed from a facility \7\ as a unit or in sections
(e.g., a pipeline), the rule requires adequate wetting of all RACM
exposed during cutting or disjoining operations; and each unit or
section to be carefully lowered to the floor and/or ground level, not
dropping, throwing, sliding, or otherwise damaging or disturbing the
RACM. After a facility component (e.g., pipeline section) containing,
covered with, or coated with RACM has been taken out of the facility as
a unit or in sections pursuant to paragraph (c)(2), it shall be
stripped or contained in leak-tight wrapping.\8\ If stripped, the
owner/operator may either adequately wet the RACM during stripping; or
use a local exhaust ventilation and collection system designed and
operated to capture the particulate asbestos material produced by the
stripping, and this system must exhibit no VE to the outside air, or be
designed and operated in accordance with 40 CFR 61.152 (air cleaning).
For removal of A/C pipe, the owner/operator must ensure that no VE are
exhibited during the removal of the A/C pipe and that all A/C pipe is
kept adequately wet to minimize the release of asbestos emissions,
unless one of the other specific provisions of the Asbestos NESHAP is
followed. Additional requirements apply to the waste handling and
disposal.
---------------------------------------------------------------------------
\7\ See 40 CFR 61.145(c)(2).
\8\ For large facility components such as reactor vessels, large
tanks, and steam generators, the RACM is not required to be
stripped. However, other requirements for such components apply.
---------------------------------------------------------------------------
The work practices in the Asbestos NESHAP that apply to the removal
and replacement of A/C pipe include procedures for emission control,
handling of asbestos waste, and asbestos waste disposal. These work
practices are discussed in the sections below.
1. Procedures for Emission Control
The principal controls in the Asbestos NESHAP for renovations such
as pipe replacement operations include requirements that the RACM be
adequately wetted to minimize VE during pipe replacement operations
involving RACM, and that asbestos waste be handled, collected, and
disposed of properly. The emission control requirements must meet the
standard for no VE. ``Adequately wet'' means to sufficiently mix or
penetrate with liquid to prevent the release of particulates. If VE are
observed coming from RACM, then that material has not been adequately
wetted. However, the absence of VE is not sufficient evidence of being
adequately wet. Typically, the emission controls used to achieve
adequate wetting include a fine water spray (or a mist).\9\ The
Asbestos NESHAP (40 CFR 61.145(c)(6)) requires that, after removal, the
RACM must remain adequately wet until collected and contained, or
treated in preparation for disposal in accordance with 40 CFR 61.150.
---------------------------------------------------------------------------
\9\ While not required under the Asbestos NESHAP, the EPA
recommends the use of surfactants to amend the water used to keep
ACM adequately wet because these water amendments greatly enhance
the ability of water to penetrate and mix with ACM.
---------------------------------------------------------------------------
The Asbestos NESHAP specifies at 40 CFR 61.150(a)(5) that the
asbestos-containing waste material (ACWM) handling requirements do not
apply to Category I nonfriable ACM waste (asbestos-containing packings,
gaskets, resilient floor covering, and asphalt roofing products
containing more than 1-percent asbestos) and Category II nonfriable ACM
waste (any other nonfriable ACM containing more than 1-percent
asbestos) that did not become crumbled, pulverized, or reduced to
powder.
2. Handling of Asbestos Waste
Asbestos containing waste materials from activities regulated by 40
CFR 61.145 must be handled, collected, and disposed of in accordance
with 40 CFR 61.150. No VE may be discharged to the outside air during
the collection, processing, packaging, or transportation of any ACWM.
All ACWM must be kept adequately wet and sealed in leak-tight
[[Page 18047]]
containers (40 CFR 61.150(a)(1)) or processed into a nonfriable form,
such as a nonfriable pellet or other shape (40 CFR 61.150(a)(2)).
3. Waste Disposal
The Asbestos NESHAP requires all ACWM to be deposited as soon as is
practical in a waste disposal site operated in accordance with the
provisions of 40 CFR 61.154 or an EPA-approved site that converts RACM
and ACWM into nonasbestos (asbestos-free) material according to the
provisions of 40 CFR 61.155.
E. What techniques are approved for removal and replacement of A/C
pipes?
Even A/C pipes in good condition (which would be Category II
nonfriable ACM) become regulated ACM, if the pipe has a high
probability of becoming or has become crumbled, pulverized, or reduced
to powder by the forces expected to act on the pipe during the
renovation activities. Moreover, most of the A/C pipe being replaced by
municipalities is likely to be in poor condition (i.e., friable) due to
the degradation over time as discussed in the section II of this
document.
The EPA has previously determined \10\ that pipe removal is
generally a renovation unless it is associated with the demolition of a
structure (in which case, it is a demolition). One applicability
determination from 1994 states that removal of A/C pipe ``. . . is a
renovation because the pipe is not a load bearing structural member.''
---------------------------------------------------------------------------
\10\ See the applicability determination number a960010, October
12, 1994, from John Rasnic regarding removal of pipe, which may be
found in the EPA's Applicability Determination Index.
---------------------------------------------------------------------------
The accepted technique to remove and replace A/C pipes is known as
``open trench replacement.'' In open trench replacement, the pipe is
located, cleaned, and inspected. Because pipes run beneath and cross
transportation corridors, traffic is rerouted to available detours.
Temporary water and sewer service is installed to handle the water
supply and/or wastewater handling affected by the disruption of
service. Other utilities (electricity, cable, optical fiber) that may
obstruct or interfere with pipe replacement are also identified. Once
the location of the pipe and all utilities are identified, the road
surfacing, and other structures, such as sidewalks, medians, etc., are
removed and an open trench is dug to expose the length of pipe to be
replaced. A pipe cutter is clamped around the A/C pipe being replaced,
and it is scored along the outside of its circumference while water is
applied to prevent emissions of asbestos to the atmosphere, which may
occur along the line of cutting. The pipe is snapped along the cut and
the process is repeated to produce transportable 6- to 8-foot sections
of pipe. Asbestos cement pipe in poor condition may resemble wet
cardboard in the way it responds to these removal activities. It can
simply collapse and tear into smaller pieces, rather than snap, as A/C
pipe in good condition is known to do. Each pipe section is removed,
wrapped in plastic, and placed on a truck labelled according to
regulations for asbestos waste disposal. This process of snap cutting
and removal is repeated for the entire length of A/C pipe to be
replaced.
No AWPs for the replacement of A/C pipes have yet been approved.
III. Alternative Work Practice Request
A. What is the close tolerance pipe slurrification technique for A/C
pipe replacement?
The EPA received a request from Trenchless Consulting, LLC, in July
2017, for approval of an AWP, known as the ``Close Tolerance Pipe
Slurrification'' (CTPS) method, for the removal and replacement of A/C
pipes. This is one of two AWPs requested. The second one, which
involves a technique commonly known as ``pipe bursting'' is still under
consideration. We are not discussing ``pipe bursting'' in this Federal
Register document and no decision has been made on whether or not to
propose approval of ``pipe bursting'' as an AWP.
Documentation for CTPS is found in the Docket, and includes
photographs and video of the CTPS process demonstration on clay
pipe,\11\ schematics of the process, and descriptions of the process.
The CTPS method uses an equipment train to deliver drilling fluids and
clays in suspension through a pipe in the center of the train. The
equipment train uses a cutting head which grinds the underground A/C
pipe to a fine grain while the fluids maintain the adequately wet
requirements of 40 CFR 61.145 and entrain the finely ground pipe
fragments in a slurry. During this process, the slurry mixes with the
drilling fluids to create a homogenous \12\ wet cementitious material,
which is removed from the underground pipe path at vertical access
points (i.e., manholes, trenches, other vertical access cuts). These
vertical access points are sheathed with a nonpermeable lining, such as
plastic, at the beginning and end of the run of pipe being replaced.
The cementitious slurry hardens into a nonfriable A/C after 48-56
hours. The proposed CTPS AWP employs dust suppression using amended
water at all vertical access points to maintain the no VE and
adequately wet requirements of the Asbestos NESHAP, as required by 40
CFR 61.145 and 40 CFR 61.150.
---------------------------------------------------------------------------
\11\ According to the demonstration of the CTPS process by
Portland Utilities, clay pipe is pulverized and slurrifies similarly
to A/C pipe when subjected to the CTPS process.
\12\ A homogenous mixture is one in which the components are
uniformly distributed throughout the mixture.
---------------------------------------------------------------------------
The EPA is proposing to consider the slurry that is formed by the
CTPS AWP for A/C pipe to be nonfriable once hardened. This is important
because the typical A/C pipe that is replaced is usually friable in
many places and in poor condition. The proposed CTPS AWP converts all
the ACM of the A/C pipe into a nonfriable material which is disposed of
in a landfill permitted to receive ACWM. A skim coat of the nonfriable
cementitious ACM remains on the outer rim of the new pipe.
Because disposal takes place before the slurry hardens, and the
test to determine friability takes place after the slurry hardens, the
slurry must be sealed in containment at disposal (rather than disposed
openly pending the outcome of the test). Although the Asbestos NESHAP
does not require containment of nonfriable ACM, this AWP must ensure
the ACWM is contained because the test indicating the ACWM is
nonfriable would not yet have been conducted at the time of disposal
(the friability test is done on a sample of the material that has cured
and hardened over a period of 48 to 56 hours).
In contrast to the Asbestos NESHAP work practices for ACPRPs
conducted in temperatures below freezing, the CTPS method may only be
used when temperatures are above 32 [deg]F (0 [deg]C) to prevent
freezing the slurry, drilling fluids, and/or the amended water needed
to maintain adequate wetting.
B. What is the EPA's proposed action on the AWP request?
The EPA believes that the CTPS work practices are ``consistent with
the EPA's intent to distinguish between material that could release
significant amounts of asbestos fibers during demolition and renovation
operations and those that would not, and to prevent significant
emissions of asbestos fibers to the atmosphere.'' (see 55 FR 48408,
November 20, 1990 Asbestos NESHAP final notice, in our statements in
response to comments on friable vs. nonfriable materials). The EPA is
proposing that, for the following five reasons, CTPS is at least
equivalent to
[[Page 18048]]
the Asbestos NESHAP process for A/C pipe removal.
First, this technique of replacement only exposes a small portion
of the A/C pipe, thereby preventing significant emissions of asbestos
to the atmosphere, a part of the overall reduction in emissions
potential. As described in more detail below, the CTPS approach only
excavates the A/C pipe at predetermined points along the pipe's path.
Vertical access cuts are made to remove A/C pipe only at the beginning
and end of the length of pipe to be removed and in designated vertical
access points to reduce pressure buildup of the slurry. This limited
excavation reduces the level of exposure to asbestos emissions from the
A/C pipe remediation project.
Second, during periods where ACM is exposed, it is in the liquid
slurry form and is considered adequately wet and, thus, does not become
airborne, where it could be available for inhalation. The slurry is
pumped out of these points into an enclosed tank to be taken to a waste
disposal site approved to receive asbestos.
Third, the CTPS AWP uses amended water to improve dust suppression
at all cuts, trenches, and vertical access points where A/C pipe may be
exposed to the ambient air. The pipe is otherwise not exposed to the
air.
Fourth, a skim coat of slurry, which contains ACM and remains on
the new pipe, is not loose in the soil, but adheres to the surface of
the new pipe. The skim coat fills the annular space created by the
close tolerance drill through the ground as it pulls the new pipe
through. Therefore, it has a structural support preventing the thin
coating from being crushed, and also is not free to migrate to the
surface as a result of soil movement, such as frost heaves.\13\
Furthermore, the existence of asbestos in the skim coat is noted on the
utility records so that owners/operators are advised of its presence.
---------------------------------------------------------------------------
\13\ Frost heaves occur in the top 3 feet of soil, and occur at
low temperatures when available moisture in the soil freezes,
expanding, and displaces materials with higher surface area
(regardless of density) upward due to decreasing pressure. In this
way, chunks of material of various densities may be moved to the
surface.
---------------------------------------------------------------------------
Fifth, once hardened, the skim coat is nonfriable and has
properties of cement: Similar to light-weight flowable fill (concrete)
purchased from concrete plants, the skim coat has a strength of 50-150
pounds per square inch. Once hardened, the skim coat has static
properties such that it does not settle or compress further. Once the
skim coat is in place, it can only be removed by force, i.e., using a
pipe saw or a pipe cutter. Additionally, the skim coat is not subject
to corrosional forces from inside the pipe. For more information on the
properties of the skim coat that remains on the pipe, see docket item
``Skim Coat Properties, email correspondence from Mike Woodcock,
Portland Utilities Construction, January 2018.''
The Asbestos NESHAP focuses on asbestos containing materials and
their decline into friable material. Since the advent of new methods
which were not available at the time of the last amendment to the rule,
this may be a procedure whereby friable A/C pipe in poor condition is
partially remediated back to a nonfriable state, and its properties are
similar to the properties of other cement products such as flowable
fill concrete.
Close tolerance pipe slurrification differs from the conventional
work practices in which the entire pipe, much of which is in poor
condition and may be friable, is excavated and exposed, cut into
numerous 6- to 8-foot transportable sections, sealed in leak-tight
wrapping, labeled, and transported to an approved asbestos waste
disposal site. Five A/C pipe replacement guidance documents from state
and local agencies (from Massachusetts, Maine, Oregon, Utah, and the
city of Richmond, Virginia) are available in the docket for reference
on the conventional work practices.
Consequently, the EPA believes that by following the CTPS AWP,
adequately wet and no VE protocols, and exposing only small sections of
A/C pipe to the air, asbestos emissions to the atmosphere are
minimized, and the AWP would achieve an emission reduction at least
equivalent to the current Asbestos NESHAP.
While the Asbestos NESHAP (and associated applicability
determinations) contemplate and provide direction on a number of
situations for handling and managing asbestos, the situation whereby
friable ACM is turned into nonfriable ACM is not one that is
contemplated under the rule. The EPA is proposing that when the CTPS
work practices are adhered to as described in this document, and when
the test for friability confirms that the resulting hardened slurry
(skim coating) is nonfriable ACM, the resulting material can be
regulated as nonfriable ACM. Under 40 CFR 61.145(c)(1)(iv) of the
Asbestos NESHAP, under certain conditions nonfriable ACM need not be
removed, if they are Category II nonfriable ACM and the probability is
low that materials will become crumbled, pulverized, or reduced to
powder during demolition. We are proposing that the nonfriable skim
coating of ACM left on the outer rim of the new pipe be allowed to also
remain in place.
The EPA is proposing that when CTPS is used to remove the
underground A/C pipe, while maintaining no VE and the adequately wet
requirements of 40 CFR 61.145 and 40 CFR 61.150(a), removing the old A/
C pipe, converting all A/C pipe to Category II nonfriable ACM, and
replacing the underground A/C pipe with new pipe, then CTPS is at least
equivalent, in terms of emission reductions, to the work practices in
the Asbestos NESHAP as they apply to renovations.
The Asbestos NESHAP waste disposal requirements include deed
notations for inactive asbestos waste disposal sites, where ACWM (e.g.,
friable ACM) has been left behind in the ground. The EPA included this
provision in the Asbestos NESHAP for situations in which manufacturing
waste had been left behind, sometimes buried on property, and that
property later was sold for development. Without a deed notation to
warn potential buyers of its presence, new owners could accidentally
expose themselves to asbestos (for example, by installing a swimming
pool, driveway, or digging a basement). The EPA, therefore, added
requirements for property deed notation when ACWM has been left behind
in the ground, creating an inactive asbestos waste disposal site.
The EPA is proposing that the nonfriable ACM resulting from CTPS
would not be subject to deed notations. However, as is current
practice, the EPA proposes that owner/operators (e.g., municipality or
utility) using the CTPS AWP would be required to maintain utility maps
with the actual location of each ACPRP identified by the 6-digit
latitude and longitude coordinates of the newly laid line, and that the
utility maps would note the line as covered by a skim coat of ACM for
future work.
The EPA is also proposing that the other requirements in the
Asbestos NESHAP that apply to renovations, including notification
requirements found in 40 CFR 61.145(b), would apply to the CTPS AWPs.
Additionally, the EPA is proposing that the waste handling and disposal
requirements found in 40 CFR 61.150 and 61.154 would apply to the
slurry that is removed at the ACPRP.
IV. What are the proposed work practices for A/C pipe replacement?
The EPA is seeking the public's input on Trenchless Consulting's
request that the EPA approve the CTPS approach as an AWP under the
Asbestos NESHAP. We are seeking comments on whether
[[Page 18049]]
the CTPS work practices are equivalent to those in the Asbestos NESHAP,
including adequate wetting requirements, no VE, notification,
containment, labeling, waste handling, waste transportation, and
disposal of ACWM. The materials supporting the request for this
approval are available in the Docket and include industry descriptions
of the CTPS work practice and processes, the process patent, records of
the EPA's communication with the industry requestors, and the EPA's
observations of the methods conducted on PVC and clay sewer pipe.
Based upon our initial review of the proposed AWP request, the
demonstrations of the work practice, and written materials including
equipment, materials, slurry characteristics, testing, and waste
specifications, we propose that, by complying with the following list
of requirements, this proposed AWP will achieve emission reductions at
least equivalent to emission reductions achieved under 40 CFR 61.145,
40 CFR 61.150, and 40 CFR 61.154, as required by the applicable
Asbestos NESHAP, provided that adequate wetting accompanies all
vertical access points, access trenches, and manholes to prevent VE,
and that the A/C cementitious material resulting from this process is
properly handled and contained during and after removal and properly
disposed of as required by the Asbestos NESHAP.
The patent related to this process, ``Method of Replacing an
Underground Pipe Section,'' is available from the U.S. Patent Office,
patent number US8,641,326B2; February 4, 2014, and a copy is available
in the docket. That patent deals with the replacement of low-pressure
sewer pipes and indicates some parameters that may be different from
the work practices in this notice, depending on the soil composition,
depth of pipe, and serviceable use of the pipe (e.g., a low-pressure
sewer, waste water, or fresh water pipe). While this patented process
is one used by the company requesting approval of this AWP, an owner/
operator would not have to license the patent and could choose
different equipment in order to follow the work practices of this
notice.
A. What is the proposed CTPS AWP?
The proposed CTPS AWP is as follows:
1. Vertical Access Points
Vertical access points (e.g., manholes, trenches) are made at
designated intervals along the length of pipe replacement. The distance
between vertical access points is a function of the soil type, pipe
size, pneumatic pressure on the CTPS head, and frictional drag on the
line; and is determined for each project on a case-by-case basis by the
owner/operator. Incorrect estimation of the vertical access point
locations may result in a malfunction. The owner/operator must not
disturb A/C pipe during the digging out of these access points. Water
and suction should be used to uncover as much of the A/C pipe as is
needed to begin the CTPS process.
2. Removal of Pipe at Terminals and Vertical Access Points
At the starting and terminal points, and at designated intervals
along the length of pipe replacement, sections of pipe are cut and
removed at the vertical access points (i.e., manholes, trenches). The
owner/operator must handle all sections of A/C pipe in accordance with
40 CFR 61.145 and 40 CFR 61.150 of the Asbestos NESHAP.
3. CTPS Equipment Train
The CTPS technique should use a drilling head train with a slightly
larger diameter than the pipe being replaced. This technology must use
a heavy duty four-stage cutting and wetting train, made of hardened
carbon steel, which is able to be fed directly around the pipe to be
replaced. The cutting head must be drawn around the existing pipe and
must be capable of grinding the old A/C pipe to a fine powder using a
liquid delivery system as described in section IV.A.4 of this preamble.
The process must return the A/C pipe to a cementitious slurry that is a
homogenous mixture and stays adequately wet through disposal according
to the requirements of 40 CFR 61.145. The owner/operator must ensure
that the CTPS train pulls the replacement pipe behind it, and that no
ACM contacts the inside of the new pipe.
4. Liquid Delivery
The horizontal drilling train must be equipped with ports to
deliver liquid materials to the drilling head. Drilling fluids and
bentonite clay should also be delivered through these ports to reduce
frictional drag on the line, and to lubricate the interface along the
soil to pipe line.
5. Trackable Pipeline
The owner/operator would be required to ensure that the new
pipeline is trackable by steel cable (or other durable trackable
material) laid with the new pipe.
6. Slurry Characteristics
The owner/operator would be required to ensure that no visible
emissions are discharged to the air from the slurry, and that the
slurry is a homogenous mixture comprised of finely ground A/C pipe,
drilling fluids, bentonite clay, and other materials suspended in
solution that, when cured (a period of 48-56 hours), re-hardens so that
it meets the sample friability test in section IV.D.2 of this preamble.
The slurry must meet the no visible emissions requirements of 40 CFR
61.145 and 61.150.
7. Slurry Removal, Containment, Transportation, and Disposal
The A/C pipe slurry is removed at vertical access points using a
vacuum attached to a tank (e.g., vacuum truck). The owner/operator
would be required to ensure that the slurry remains in an adequately
wet state during the slurrification process and remains in containment
throughout the removal, transportation, and disposal processes, meeting
the requirements of 40 CFR 61.145 and 40 CFR 61.150. The slurry must be
contained and in slurry form at the time of disposal in a landfill
permitted to accept ACWM and meeting the requirements of 40 CFR 61.154.
The slurry must be managed at the disposal site using procedures
meeting the requirements of 40 CFR 61.154.
8. Adequate Wetting With No VE
Any opening to the atmosphere along the pipe is a potential source
of asbestos emissions to the outside (ambient) air. The owner/operator
would be required to ensure that dust suppression equipment (i.e., dust
suppression apparatus or manual misting) using amended water is placed
at each vertical access point. If a new trench is dug to resolve a
malfunction, the owner/operator would be required to ensure that the
new trench is equipped with dust suppression and follow the procedure
in paragraphs (1) and (2) above. Amended water is water to which
surfactant chemicals (wetting agents) have been added to reduce the
surface tension of the water.
B. What notification requirements would apply?
If an underground ACPRP meets the applicability and threshold
requirements under the NESHAP, then the EPA (or the delegated agency)
must be notified in advance of the replacement in accordance with the
requirements of the Asbestos NESHAP at 40 CFR 61.145(b). See 40 CFR
61.145 for more information on the notification requirements.
[[Page 18050]]
C. What inspection, operation, and maintenance requirements would
apply?
1. Inspection
Prior to using the CTPS for an ACPRP, the owner/operator would
conduct underground pipe inspections (e.g., by using remote
technologies like robotic cameras) and shall identify, locate, and mark
onto an underground utility map of the area all identified potential
areas of malfunctions, such as changes in pipe type, drops in the line,
broken and off-center points, and changes in soil type.
2. Operation and Maintenance
The owner/operator of a CTPS method system is required to install,
operate, and maintain the drilling head train, CTPS liquid delivery
system, and all equipment used to deliver adequate wetting at all
vertical access points and cut lengths of pipe in accordance with their
written standard operating procedures. The records must be kept in
accordance with section IV.F.1 of this preamble.
D. What sampling, testing, and utility map notation requirements would
apply?
1. Sample Collection
After the slurry has been pumped from the vertical access points,
but before disposal, the owner/operator of a CTPS method system is
required to collect a 2-inch roughly spherical wet sample of the
slurry. A single sample must be collected for each project discharging
to a single enclosed tank. The owner/operator would be required to seal
the sample in leak-tight wrapping and allow the sample to harden and
dry (usually 48-56 hours).
2. Sample Friability Test and Certification
When the sample is hardened and dry, the owner/operator would be
required to attempt to crush the sample by hand. The sample that cannot
be crumbled, pulverized, or reduced to powder by hand pressure is
nonfriable, and the remaining slurry from that pipe replacement job is
likewise nonfriable. After testing, the owner/operator would be
required to ensure that the sample is packaged in leak-tight wrapping
for storage, labeled ``Asbestos Containing Material. Do not break or
damage this sealed package,'' dated according to the ACPRP date of
generation, stored in a secure location that is inaccessible to the
general public (such as a locked storage unit), and is maintained by
the owner/operator for a period of 2 years. After this 2-year retention
period, the sample may be disposed of in a landfill permitted to accept
ACWM.
a. If the sample cannot be crushed, crumbled, or reduced to powder
by hand pressure, the owner/operator would be required to certify this
as follows: ``The hardened slurry sample from the ACPRP conducted on
(date) at (location) could not be crushed, crumbled, or reduced to
powder by hand pressure. I am aware it is unlawful to knowingly submit
incomplete, false, and/or misleading information and there are
significant criminal penalties for such unlawful conduct, including the
possibility of fine and imprisonment.'' The owner/operator would be
required to maintain a signed certificate of this statement so that it
is available to the EPA Administrator, local, and state agency
officials upon demand.
b. If the sample can be crushed, crumbled, or reduced to powder by
hand pressure, the owner/operator would be required to follow the
malfunction reporting requirements in IV.F. 2 below.
3. Utility Map Notations
Owner/operators would be required to note utility maps according to
the actual location identified by the 6-digit latitude and longitude
coordinates of the newly laid line. Notations would have to be
maintained for the life of the new pipe by the owner/operator (e.g.,
municipality or utility), and would have to be labeled as covered by a
skim coat of ACM for future work.
E. What labeling and transportation requirements would apply?
Because all A/C pipe being replaced using the CTPS technique is
converted to a nonfriable state during the replacement, it would be
categorized as Category II ACM and would need to be labeled and
transported in accordance with the corresponding requirements of 40 CFR
61.145 and 40 CFR 61.150 in the Asbestos NESHAP.
F. What recordkeeping and reporting requirements would apply?
1. The owner/operator would be required to record and maintain for
a period of 2 years the following data:
a. Date(s) from beginning to end of each ACPRP;
b. Location(s) of the A/C pipe(s) replaced using CTPS, identified
by 6-digit latitudinal and longitudinal coordinates for each ACPRP;
c. Diameter and length of A/C pipe replaced at the ACPRP;
d. Total amount of slurry generated at the ACPRP;
e. Total amount of slurry disposed by the owner/operator from the
ACPRP;
f. Slurry disposal site;
g. Manifest of ACM slurry disposal; and
h. Malfunction records (if applicable).
i. Records of VE events and their duration (including the time and
date stamp) of any VE event;
ii. Records of when and how each VE event was resolved. Indicate
the date and time for each VE period, whether the VE event occurred at
an exposed manhole, trench, or other vertical access point, and the
number of openings to the ambient air affected;
iii. Procedure used to resolve each VE event; and
iv. Results of each sample friability test that indicates the
slurry is friable, as required by IV.D.1 and 2 above.
i. Records of the standard operation procedures for the
installation, operation, and maintenance of the drilling head train,
CTPS liquid delivery system, and all equipment used to deliver adequate
wetting at all vertical access points and cut lengths of pipe.
2. Each owner/operator is required to submit the following reports
to the Administrator after each occurrence, as follows:
a. Malfunction Report. The malfunction report must include the
records in section IV.F.1.h.i.-iv of this preamble. The malfunction
report must be submitted as soon as practical after the occurrence, but
in no case later than 30 days.
b. ACPRP Report. The ACPRP report must be submitted to the Asbestos
NESHAP program office within the EPA Regional office in which the ACPRP
is located. The report may be submitted electronically when the means
to do so are available. The EPA Regional office may, at their
discretion, waive this requirement and delegate this reporting to the
state and municipality. If the EPA Regional office has waived the
reporting, and if the state or municipality is unable to receive
electronic reports, then only a hard copy is required to be submitted.
These reports must be postmarked or electronically submitted within 30
calendar days of completion of the ACPRP.
V. Request for Comments
We solicit comments on all aspects of this request for approval of
CTPS as an AWP for the work practice standards specified in 40 CFR part
61, subpart M, the Asbestos NESHAP. We specifically seek comments
regarding whether the AWPs, as described in section IV above, will
achieve emission reductions at least equivalent to the work practices
in the
