This section establishes minimum work practice requirements
for asbestos abatement activities. All asbestos abatement activities are
subject to these work practice requirements. All projects must be performed in
accordance with an applicable project design, as set forth in these
rules.
A.
General Work Practice
Requirements. Asbestos abatement activities, exclusive of asbestos
associated activities, must comply with the following work practice
requirements:
(1) A certified Asbestos
Abatement Project Supervisor must be designated as the lead supervisor for the
project and must be present at the work site at all times personnel are within
the regulated area.
(2)
Establishing the Regulated Area. Prior to starting an asbestos abatement
activity, the Asbestos Abatement Contractor must establish the regulated area.
For activities where containment is not required, the regulated area shall be
demarcated with barrier tape marked "ASBESTOS HAZARD" (or equivalent wording)
and OSHA warning signs, and located such that it protects persons from exposure
to asbestos and minimizes the number of persons in the area. In facilities
where plastic barrier tape may cause a safety hazard, red cloth tape may be
used.
________________________________________________________________________
Note: If establishing an exclusion zone, the exclusion zone
should be demarcated with barrier tape that is different from the tape used to
demarcate the regulated area.
________________________________________________________________________
The regulated area must include the following:
(a) Except as allowed under the provisions of
sections 7(B) and 7(D) of this rule, a work area containment meeting the
following requirements:
(i) A
polyethylene-enclosed structure formed by partitions or framing or by covering
walls and ceilings with a minimum of 2 layers of 4-mil polyethylene sheeting or
1 layer of 6-mil polyethylene sheeting, and by covering the floor with a
minimum of 2 layers of (six) 6-mil polyethylene sheeting. The surface to be
abated does not need to be covered with polyethylene sheeting. For suspended
ceiling tile system removals, containment above the ceiling also is required
for interior walls that do not extend from floor to ceiling; that is, a gap
exists above the ceiling system where asbestos fibers could migrate to areas
not being abated. Perimeter areas along interior walls therefore must be
accessed and/or removed first and 2 layers of 4-mil polyethylene sheeting or 1
layer of 6-mil polyethylene sheeting established as containment prior to
removing interior portions of the ceiling system. Exterior walls must have
critical barriers established in section 7(A)(2)(d) of this rule;
(ii) Fiber-tight seams in the polyethylene
coverings; and
(iii) An access into
the polyethylene-enclosed containment provided through the decontamination
unit.
________________________________________________________________________
Note: When containment is not required, all other work
practice requirements, including all other requirements for the regulated area,
still apply.
________________________________________________________________________
(b) A decontamination
facility consisting of aluminum, tin, fiberglass, preformed plastic, or other
impervious surface, or two layers of (six) 6-mil polyethylene sheeting.
Decontamination facilities must have (six) 6-mil polyethylene sheeting flaps or
air-locks between each chamber. Remote decontamination facilities are exempt
from the ventilation system required below. Where construction of a
decontamination unit meeting minimum size requirements is not possible due to
room size and configuration, HVAC system component locations, life safety code
requirements or restriction of safe egress for residents, a smaller than
standard decontamination facility may be constructed.
(c) A ventilation system meeting the
following requirements:
(i) The exchange of
at least 4 volumes of air per hour at a volume sufficient to establish and
maintain a pressure differential within the ambient environment of negative
0.02 inches of water column;
(ii)
The ventilation units must be operated in accordance with US EPA
recommendations set forth in Appendix J of US EPA Guidance Document EPA
560/5-85-024 (effective June, 1985) or in Appendix F to
29 CFR
Part 1926.1101 (effective August 10,
1994);
(iii) The make-up air
entering the containment must pass through the decontamination system whenever
possible, or through waste load-out and/or make-up air intakes specified by the
project design; and
(iv) The
exhaust air must be HEPA filtered before being discharged outside of the work
area and must be discharged outside the facility to a location that is not near
any intake for building ventilation. The HEPA-filtered exhaust air may be
discharged inside the facility if access to the outside is not feasible because
the distance from the regulated area to the outside of the building is too
great (such as in large industrial building or warehouses), or when health and
safety concerns, such as blocking egress from an area with limited access.. If
the exhaust air is discharged inside the facility, the contractor shall
demonstrate that the unit(s) is operating effectively by evidencing that air
samples collected from the exhaust stream are less than 0.01 f/cc or that the
audio alarm filter and/or filter change lamps and the unit(s) pressure
differential filter monitoring meter is operational.
Ventilation units may be shut down overnight when the only
source of electrical power for the project is a portable generator that must be
removed at night for site safety and security reasons. The entry into the work
area must be sealed (fiber-tight) whenever ventilation units are shut
down.
(v) The exhaust air
tubes or ducts associated with the work area ventilation system must be
fiber-tight and must be securely attached to the HEPA unit exhaust
port.
(d) Critical
barriers. Critical barriers are required for all projects.
(i) Prior to suspended ceiling tile removals,
the perimeter area above the ceiling must be accessed first, under negative
pressure with properly protected employees to allow the sealing, as critical
barriers, of penetrations and openings along the perimeter.
________________________________________________________________________
Note: Removal of perimeter ceiling tiles must be conducted as
an abatement activity subject to all applicable work practice
requirements.
________________________________________________________________________
(e) A waste load out,
if applicable.
(3)
Exclusion of Persons from the Regulated Area and Posting Signs.
(a) Individuals not directly involved in the
asbestos abatement activity must be excluded from the regulated area.
(b) Warning signs, meeting the requirements
set forth in
29 CFR
1926.1101 (effective August 10, 1994), shall
be posted at all approaches to the regulated area, and at the decontamination
and waste load out unit's outermost boundaries.
(4) Regulated Area Control. An Asbestos
Abatement Project Supervisor must be present at the work site at all times
during active abatement activities. The Supervisor must have the authority to
initiate and implement corrective action should problems or deficiencies arise
at the asbestos worksite.
(5)
Physical Barriers. Physical barriers must be established if indicated in the
project design.
(6) Personal
Protective Equipment. An individual involved in an asbestos abatement activity
or an individual who enters the regulated area, excluding the clean room, must
be provided with and wear appropriate respiratory protection and personal
protective clothing. Minimum respiratory protection shall be 1/2-faced negative
pressure respirator equipped with HEPA filters. Minimum protective clothing
shall be disposable full body suits, including head and foot coverings. Wearing
a nylon brief type bathing suit underneath disposable full body suits is
allowed. Gym shorts, "cut-offs" or underwear are not considered to be bathing
suits.
________________________________________________________________________
Note: OSHA also regulates asbestos activities involving
respirators and personal protective equipment. OSHA regulations may require a
higher degree of respiratory protection and/or protective clothing.
________________________________________________________________________
(7) Isolation of HVAC Systems. All
intake openings, exhaust openings, and any holes in the building HVAC system
and its components located within the regulated area must be fiber-tight and
covered with two-layers of (six) 6-mil fiber-tight sheeting, and all seams in
the system must be taped to be fiber tight.
(8) Covering of Movable and Immovable
Objects.
(a) Movable objects within the
regulated area must be removed or, if not feasible, treated as an immovable
object below.
(b) Immovable or
fixed objects within the regulated area must be wrapped with two layers of six
(6) mil thick (minimum) polyethylene sheeting that is fiber-tight prior to the
commencement of abatement activity.
(9) Air and Project Monitoring. All asbestos
abatement activities are subject to the following air and project monitoring
requirements:
(a) An air monitoring program
that is developed by an Asbestos Air Monitor must be in place and be consistent
with these rules; and
(b) A project
monitoring program, if applicable, that is developed by an Asbestos Air Monitor
must be in place and be consistent with these rules.
________________________________________________________________________
Note: An air monitoring program consists of air clearance
sampling at a minimum, and may include background and area samples. See
"Monitoring". OSHA requires personal sampling for most activities.
________________________________________________________________________
(10) Wetting of ACM.
Prior to removal of ACM, including removal of components covered with thermal
system insulation, all ACM must be adequately wetted with water, except as
provided below. Throughout the removal, storage, transport, and disposal
processes, ACM must be kept adequately wet.
(a) Wetting ACM not required under the
following conditions:
(i) When the
temperature inside the regulated area is below 32[DEGREE]F and heating the area
is neither feasible nor practical (e.g., abandoned warehouse or
roof);
(ii) When electrical
conditions exist that are noted in the design plan and demarcated in the
specific work area, and that would render that specified area hazardous to
shock and/or electrocution hazards; or
(iii) When operational high-pressure steam
lines are being abated or repaired.
(iv) Wetting metal jacketed piping during
wrap and cut operations. ACM exposed during glove-bagging associated with the
wrap and cut process must be wetted in accordance with standard glove-bag
procedures.
________________________________________________________________________
Note: When not wetting ACM during removal is allowed, the ACM
must still be adequately wet during storage, transport, and disposal.
________________________________________________________________________
(11)
Containerization of Waste at Elevations Exceeding 10 Feet. Excluding removal of
acoustical, sprayed-on, troweled-on, or fireproofing ceiling materials, ACM
must be containerized at the height of removal if the elevation of the material
is 10 feet or greater from the ground or floor. Roofing waste may be lowered to
ground level in a closed cluster in a pan scale or similar equipment prior to
packaging.
(12) Containerization of
Asbestos Waste. Prior to removal from the regulated area, asbestos waste must
be containerized in fiber-tight leak-proof packaging and properly labeled, in
accordance with OSHA
29 CFR
Part 1926.1101 (effective August 10, 1994).
(a) Friable asbestos waste
andasbestos-containing cementitious materials removed from inside of occupied
facilities. Friable asbestos waste that does not contain components with sharp
edges must be adequately wetted and then containerized in two (2) polyethylene
bags with a six (6) mil minimum thickness for each bag. Bags shall be then
individually sealed in a fiber-tight manner by first removing air from the bag,
and then twirling the open end of the bag sufficiently enough to permit the
twirled end to be folded over and wrapped securely with duct tape. Fiber-tight
drums may be used in lieu of bags to package waste. Liners inside dumpsters and
roll-offs can not be used to meet this containerization requirement. If,
however, the configuration or shape of the asbestos waste is such that the
containerization of the asbestos waste in bags is not feasible, then it shall
be adequately wetted and thoroughly wrapped in a minimum of two (2) layers of
six (6) mil polyethylene sheeting with all joints, seams and overlaps sealed in
a fiber-tight manner. Asbestos-containing cementitious materials removed from
inside of occupied facilities must be containerized in accordance with this
section All friable asbestos shall be disposed of in a landfill licensed to
accept friable asbestos waste.
(b)
Non-friable asbestos waste. Non-friable waste may be packaged as set forth in
section 7(A)(12)(a) of this rule. At a minimum, non-friable waste shall be
wetted and containerized in leak proof containers for delivery to a landfill
that is licensed to accept non-friable asbestos waste. Shredding, crushing, or
any other form of volume reduction prior to placement in the landfill will
render non-friable asbestos waste subject to the containerization requirements
set forth in section 7(A)(12)(a) of this rule.
(c) Work area polyethylene waste. Once
visually clean, work area polyethylene sheeting must be removed and disposed
of, either as asbestos or non-asbestos waste.
(13) Asbestos Waste Storage Requirements.
On-site storage of asbestos waste, defined to be storage at the street address
of the abatement site, is subject to the following requirements:
(a) Waste must be stored in a secure
container or area accessible to authorized persons only;
(b) Waste packaging must be free of visible
debris prior to placement in the storage area or storage container;
(c) Waste must not remain on-site longer than
five (5) days following completion of asbestos abatement activities;
and
(d) Waste must be tracked by
written documents, such as bill of lading or manifest, evidencing the current
location of the waste at any time prior to final disposal.
(14) Personal Decontamination Requirements
(a) An individual must decontaminate prior to
exiting the regulated area. Personal decontamination shall be achieved by
removing all clothing and footwear except a bathing suit, if worn, and
thoroughly showering with soap and water at a contiguous or remote
decontamination facility. Respirators must be worn into the shower unit, and
washed and cleaned as part of the decontamination procedure.
(b) Clothing or footwear used or worn in the
regulated area must not leave the equipment room unless containerized for reuse
inside a regulated area, cleaned, or disposed of. Clothing worn under
protective suits and footwear must be designated for asbestos use only, be
easily identifiable by sight and be permanently marked or labeled (minimum 3/4
inch lettering) as "Asbestos Clothing" on the outside of the clothing or
footwear. Containerized clothing or footwear must be opened only inside a
regulated area, excluding the clean room.
(c) Only impervious materials such as rubber,
polyethylene, etc., may be cleaned in the decontamination facility. Clothing
and other pervious materials, such as leather boots, must be cleaned according
to OSHA requirements.
(d) Personal
decontamination requirements for use with a remote decontamination unit.
(i) Each worker/supervisor shall be provided
with appropriate personal protective and respiratory equipment as required by
OSHA 1926.1101 effective August 10, 1994, including but not limited to, a
half-face respirator (at a minimum) and a protective suit (e.g., tyvek) or
designated "Asbestos Clothing". Wearing a bathing suit underneath disposable
full body suits is allowed.
(ii)
Each worker/supervisor shall don their appropriate personal protective
equipment in a manner such that the protective suit (e.g. tyvek) can be removed
while the respirator is still being worn.
(iii) Before proceeding to and entering into
a regulated area, each worker/supervisor shall remove all street clothes and
footwear in the clean room of the remote decontamination facility.
(iv) Workers/supervisors wearing "Asbestos
Clothing" as provided in section 7(A)(14)(b) of this rule shall change into
their Asbestos Clothing in the equipment room, first donning their respirator
in the clean room, before proceeding to the equipment room. In the equipment
room they shall place a clean protective suit and booties over their Asbestos
Clothing and shoes before proceeding to the regulated area. The protective suit
and booties can then be removed once inside the regulated area.
(v) Each worker/supervisor shall be provided
with a clean, unused suit to carry to the regulated area. This suit shall be
left at the designated egress point into the regulated area to be used when
exiting from the regulated area.
(vi) Exiting the regulated area. Each
worker/supervisor shall first remove all visible debris from the protective
suit and then shall put the new clean unused suit that was left at the
designated egress point to the regulated area entryway over their contaminated
suit before proceeding to either another work area or the decontamination
facility equipment room where both suits shall be removed in unison.
Respirators shall not be removed during this procedure and shall be worn at all
times until they are removed in the shower room, during showering, as part of
the decontamination process that must be performed at the conclusion of the
day's shift or at any scheduled break period during the shift, including but
not limited to, the lunch break.
(15) Equipment and Waste Decontamination
Requirements
(a) All equipment, supplies, and
materials, including properly containerized waste material, work area
ventilation units, HEPA vacuums, vacuum hoses, water hoses, extension cords,
ladders, etc., must be completely decontaminated and free of visible debris
before removal from containment.
(b) Where the size and/or shape of the
equipment, supplies, and materials is such that decontamination is neither
possible nor feasible (e.g., wood), then the object shall be properly
containerized or wrapped in a minimum of two (2) layers of fiber-tight 6-mil
polyethylene sheeting for disposal or reuse in an active containment, and
cleaned of visible debris prior to removal from the regulated area.
(16) Decontamination of Work Area
Ventilation Units
(a) A work area ventilation
unit must have the exterior filter(s) removed, immediately wetted, and disposed
of as asbestos waste before the unit is taken out of containment.
(b) When the internal filter(s), including
HEPA, of a work area ventilation unit are not changed upon project completion,
the unit intake(s) and exhaust(s) must be wrapped fiber-tight with a minimum of
two (2) layers of 6-mil polyethylene sheeting before removal from
containment.
(c) Internal filters
must be removed inside an active containment, adequately wetted immediately
upon removal from the unit, and disposed of as friable asbestos
waste.
(17) Emptying of
Vacuums. HEPA vacuums must be emptied in an active containment that includes an
operating work area ventilation system and decontamination facility.
(18) Project Housekeeping
(a) Sweeping of dry ACM is prohibited;
and
(b) All removed ACM must be
containerized by the end of each workday.
(19) Existing Asbestos-Containing Debris in
the Regulated Area. Visible asbestos-containing debris that is present on
surfaces upon which the contractor will place polyethylene sheeting to
establish the regulated area shall be cleaned up prior to conducting set-up,
removal, or repair activities. The Asbestos Design Consultant must demarcate
the regulated area, incorporate into the design any existing debris within the
regulated area, and consider debris part of the abatement activity. The
Asbestos Abatement Contractor must remove existing asbestos-containing debris
on all surfaces and components within the regulated area as part of abatement
activity.
(20) Clean Up
Requirements. All visible dust and debris must be removed from the regulated
area. The regulated area must be cleaned and dry, and surface coatings must not
be applied to any surface within the regulated area, prior to conducting the
first visual evaluation and subsequent air clearance sampling.
(21) Teardown. Following the initial visual
evaluation and receipt of acceptable air clearance sampling results, the
contractor shall remove the containment, critical barriers, and the
decontamination unit from the work site. The contractor shall clean up any
visible dust or debris resulting from teardown activities prior to the final
inspection after removal of containment in accordance with section 8(B)(3) of
this rule.
(22) Project Completion.
An asbestos abatement activity is not considered complete and acceptable for
regulated area release until initial visual evaluation standard(s), standard(s)
for visual evaluation at the final inspection, and final air clearance
standards(s), (if applicable) have been met as set forth in these rules. All
applicable work practice requirements set forth in this rule must continue to
be implemented until the project is complete.
B.
Alternative Work Practice
Requirements for Demolition Activities. Except as allowed in section
7(B)(3) of this rule, demolition of a building that contains ACM shall not
commence until all ACM has been removed. A certified Design Consultant must
specify materials to be removed and/or left in place for demolition activities
conducted pursuant to this rule.
(1) Removal
of ACM from a building being demolished must comply with the work practice
requirements set forth in this section except that static clearances are
allowed when dirty or dusty conditions not related to asbestos abatement
activities exist outside the regulated area that likely will result in count
overloads to filter media. Static clearances are required when aggressive
methods are not feasible. For buildings where demolition is scheduled to occur
within 6 months of the asbestos abatement project and general access to the
building will be restricted, the regulated area does not need to include work
area containment as set forth in section 7(A)(2)(a) of this rule. Air
ventilation unit(s) shall be placed within the regulated area adjacent to
active removal activities. If this is not feasible, theasbestos abatement
contractor shall submit a non-standard variance to theDepartment stating the
reason(s) for not placing unit(s) within the regulated area.
(2) Prior to beginning a partial demolition
project where asbestos will be impacted, the remaining section(s) of the
building adjacent to the asbestos demolition must be isolated with a minimum of
two (2) layers of fiber-tight 6-mil polyethylene sheeting, and HVAC equipment
in or passing through the demolition area must be isolated with the 6-mil
polyethylene sheeting.
(3)
Demolition by Large Equipment of Buildings Containing Intact Flooring
Materials. Intact asbestos-containing flooring, does not require removal prior
to demolition by large equipment (such as bulldozers with rakes, top loaders,
backhoes, skid loaders/bobcats, hydraulic excavators, cranes with wrecking
balls, clamshells, or buckets, and other similar machinery), provided that the
following alternative work practices, as cited in (a) through (g) below, are
implemented. Contractors performing these operations must be licensed by the
Department. Employees performing the work must be certified by the Department.
OSHA training shall be documented and copies of these training certificates
shall be at the asbestos work site for any supervisors and workers certified
under the certification-by-rule provision of section 5(A)(2) of this rule. A
licensed consultant must document in writing that all flooring material is
intact and that the contractor performing the demolition activity is licensed
in accordance with the requirements of this section.
(a) A regulated area must be
established.
(b) The project must
be conducted in a manner that minimizes the release of asbestos fibers. All
necessary and appropriate measures must be taken to ensure that release of
asbestos fibers is minimized. The ACM must be kept wet at all times during the
demolition, on-site storage, transportation, and disposal activities. If
visible emissions are observed during demolition of an area with
asbestos-containing materials, work shall cease until engineering controls are
in place to prevent such visible emissions.
(c) Employees within the regulated area must
be trained consistent with OSHA
29 CFR
Part 1926.1101 (effective August 10, 1994).
Training shall be documented, and the training documentation shall be made
available immediately to the Department at the work site.
(d) Employees within the work area must wear
appropriate personal protective equipment, including a minimum of a 1/2-faced
respirator equipped with HEPA filters and full body coverings, including hand
and foot coverings.
(e) Asbestos
waste must be containerized in leak proof transport vehicles and securely
covered during transport. Waste may be segregated into asbestos waste and
non-asbestos waste as needed to meet disposal facility requirements.
________________________________________________________________________
Note: Unless theasbestos-containing flooring is separated
from all other demolition debris generated by the demolition activity, all of
the demolition debris from the activity must be disposed of as asbestos
waste.
________________________________________________________________________
(f) Disposal of
asbestos-containing demolition debris must occur at a landfill licensed to
accept construction/demolition debris or asbestos waste. The non-friable
asbestos waste must be containerized in accordance with section 7(A)(12)(b) of
this rule.
(g) A visual evaluation
of the regulated area must be performed in accordance with section 8(B) of this
rule prior to the release of the regulated area.
C.
Additional Requirements
for Enclosure and Encapsulation Activities. Enclosure and encapsulation
are considered to be asbestos abatement activities for purposes of these rules
and are subject to the work practice requirements of section 7(A) of this rule
and the following:
(1) Enclosure. Enclosures
must be labeled or identified in the permanent building records to indicate the
presence of ACM within them.
(2)
Encapsulation. Liquid penetrating encapsulants must be applied with airless
spray equipment, brushes, or rollers and in accordance with the manufacturer's
recommendations. Liquid encapsulants must not be applied to damaged or
deteriorated ACM except to seal pipe ends during a glove bag operation or
during repair operations. A bridging encapsulant (including rewettable cloth
and a pliable heat-resistant mastic) only shall be applied over damaged thermal
system insulation.
D.

Non-standard Work Practice
Requirements. Non-standard work practices may be permitted when the
standard procedure is not practicable, not feasible, not safe, or when a cost
saving alternative exists and the proposed non-standard work practice
adequately protects both human health and safety, as well as the environment,
from exposure to asbestos hazards.
Non-standard work practices must be developed by a certified
Design Consultant and must be sent in writing to the Department with the
original notification form unless unforeseeable conditions occur during a
project that warrant a request at that time. The non-standard work practice
must present clear and convincing evidence that the asbestos project is
distinctive in some way and the proposed alternative(s) to required work
practices will comply with the intent of State law and these rules. Where
applicable, the design consultant submitting the non-standard work practice
must notify the Asbestos Design Consultant who prepared the original project
design for the project of the non-standard work practice(s) submission to
theDepartment. This notification must be concurrent with the non-standard work
practice submission to the Department.
Non-standard work practices require written authorization
from the Department prior to implementation. The Department will respond to
non-standard work practice requests within 5 working days of receipt and will
indicate whether the proposal is authorized or not, and if not, why not.
The Department can revoke a non-standard work practice
approval whenever additional information is obtained or a change in project
conditions occurs.
________________________________________________________________________
Note: When given a non-standard work practice authorization,
the abatement contractor still must comply with all other applicable provisions
of this rule and other state and federal rules and regulations.

________________________________________________________________________
Note: For non-friable asbestos waste only, a copy of the
Maine Department of Environmental Protection Non-Hazardous Waste Transporter
Manifest for Category A waste may be used to meet this waste shipment records
requirement. The licensed non-hazardous waste transporter is required to
complete and maintain this manifest form and to provide a copy to the disposal
facility; asbestos abatement contractors may request a copy of this form from
the transporter.

transporter and/or the owner or operator of the designated disposal site to
determine the status of the waste shipment.
(4) Report in writing to the local, State, or
EPA Regional office responsible for administering the asbestos NESHAP program
for the waste generator if a copy of the waste shipment record, signed by the
owner or operator of the designated waste disposal site, is not received by the
waste generator within 45 days of the date that the waste was accepted by the
initial transporter. The report must include the following information:
(a) A copy of the waste shipment record for
which a confirmation of delivery was not received; and
(b) A cover letter signed by the waste
generator explaining the efforts taken to locate the asbestos waste shipment
