Or. Admin. Code § 340-248-0270 - Emission Standards and Procedural Requirements: Asbestos Work Practices and Procedures
(1) Except
as OAR 340-248-0250 provides, before
performing a demolition or renovation, the owner or operator of a demolition or
renovation activity must have an accredited inspector complete a survey
according to OAR 340-248-0270(3).
(2) The owner or operator of a demolition or
renovation activity that requires a survey under OAR
340-248-0270(1)
must send a copy of the asbestos survey report to DEQ upon request by DEQ and
keep a copy of the asbestos survey report onsite at the facility during a
demolition or renovation activity.
(3) The asbestos survey required by OAR
340-248-0270(1)
must include all of the following:
(a)
Collecting samples of all materials suspected of being asbestos-containing
materials, unless the material is presumed to be asbestos-containing material,
including at least one bulk sample for each homogeneous material suspected of
being asbestos-containing material;
(b) For sprayed or troweled on surfacing
materials, collection of at least three (3) random bulk samples for each
homogeneous area;
(c) Beginning
January 1, 2021, each sample collected under subsections (a) and (b) must be
analyzed to determine whether it is asbestos-containing material by a
laboratory with proficiency demonstrated by participation in a nationally
recognized laboratory accreditation program for asbestos testing, or
participate in, and maintain passing status in a nationally recognized bulk
asbestos proficiency testing program;
(d) An asbestos survey report that contains
the following:
(A) The date or dates that the
survey was performed;
(B) The phone
number and a copy of the certificate of each accredited inspector that
performed a survey;

address and location where the survey was performed;
(D) Name and phone number of the owner or
operator of the facility where the survey was performed and the owner or
operator of the demolition or renovation activity if different;
(E) Description of the facility and area
surveyed, including its past and current use, area square footage, approximate
construction date, and number of floors;
(F) The purpose of the survey, for example,
whether it is for a project involving pre-demolition, renovation, removal of
asbestos-containing material due to damage from fire, water, or other
purpose;
(G) Detailed description
of limitations on the thoroughness of the survey, for example an inaccessible
area; and
(H) A table listing all
of the homogeneous materials sampled and identified as asbestos-containing
material and all of the presumed asbestos-containing materials. The table must
include the following for each material:
(i)
The percent asbestos and type of asbestiform, as determined by the laboratory
that analyzes the sample;
(ii) A
description of the material color, texture, and pattern;
(iii) The location of where in the facility
the material was collected;

at the facility.
(I) A
recommendation of response actions that comply with the requirements of this
division; and
(J) A complete copy
of the laboratory report for all samples taken and analyzed under subjections
(a) - (c) of this section. The minimum requirements for the laboratory report
include:
(i) Laboratory name, address, and
phone number;
(ii) Unique sample
analysis identification number;
(iii) Bulk sample analysis results showing
asbestos content;
(iv) Name of the
analyst; and
(v) Completed chain of

(4) For a demolition or renovation of a
residential building, DEQ may approve, on a case-by-case basis, a request to
waive the survey requirement of OAR
340-248-0270(1).
The owner or operator of the residential building must submit a written request
to DEQ, along with supporting documentation that demonstrates to DEQ's
satisfaction that a survey is not warranted. The owner or operator of the
residential building must obtain DEQ's written approval waiving the survey
requirement prior to a demolition or renovation. The owner or operator of the
residential building must maintain as readily available at the demolition or
renovation site a copy of DEQ's written approval under this rule.
(5) Upon discovering asbestos-containing
materials or asbestos-containing waste materials found during demolition,
renovation, or after an emergency or unexpected event including an event that
causes fire, water, earthquake, or wind damage, the owner or operator of the
demolition or renovation activity or the owner or operator performing the
emergency response must:
(a) Stop work
immediately;
(b) Keep the exposed
asbestos-containing materials and asbestos-containing waste material,
adequately wet and cover with 6 mil plastic or equivalent at all times until a
licensed asbestos abatement contractor begins removal activities in compliance
with this division; and
(c) Have
the licensed asbestos abatement contractor remove, handle and dispose of all
friable asbestos-containing waste material and asbestos-containing waste
material as friable asbestos-containing material.
(6) A person who removes nonfriable
asbestos-containing material not exempted under OAR
340-248-0250(1)
must comply with the following:
(a) Submit
asbestos removal notification and the appropriate fee to the DEQ Business
Office on a DEQ form in accordance with OAR
340-248-0260.
(b) Remove nonfriable asbestos materials in a
manner that ensures the material remains nonfriable.
(c) A nonfriable asbestos abatement project
is exempt from the asbestos licensing and certification requirements under OAR
340-248-0100 through
340-248-0180. The exemption ends
whenever the asbestos-containing material becomes friable.
(7) Before a facility is demolished by
intentional burning, all asbestos-containing material must be removed and
disposed of in accordance with OAR
340-248-0010 through
340-248-0280.
(8) Except as OAR
340-248-0250 provides, a person
performing an asbestos abatement project must employ the following procedures:
(a) Conduct the asbestos abatement project
inside a regulated area.
(b) Remove
all asbestos-containing materials as part of the asbestos abatement project
before another demolition or renovation activity begins that would break up,
dislodge, or disturb the materials or preclude access to the materials for
subsequent removal. Asbestos-containing materials need not be removed if:
(A) They are on a facility component that is
encased in concrete or other similar material and are adequately wetted
whenever exposed during demolition or renovation; or
(B) They were not discovered before
demolition or renovation and cannot be removed because of unsafe conditions the
demolition or renovation caused.
(c) Adequately wet asbestos-containing
materials when they are being removed. In renovation, maintenance, repair, and
construction operations, where wetting would unavoidably damage equipment, is
incompatible with specialized work practices or presents a safety hazard,
adequate wetting is not required if the person performing the asbestos
abatement project:
(A) Obtains prior written
approval from DEQ for dry removal of asbestos-containing material;
(B) Keep a copy of DEQ's written approval
available for inspection at the work site;
(C) Adequately wraps or encloses
asbestos-containing material during handling to avoid releasing fibers;
and
(D) Uses a local exhaust
ventilation and collection system designed and operated to capture the
particulate asbestos material produced by the asbestos abatement
project.
(d) When a
facility component covered or coated with asbestos-containing materials is
being taken out of the facility as units or in sections, the person performing
the asbestos abatement project:
(A) Must
adequately wet an asbestos-containing materials exposed during cutting or
disjointing operation;
(B) Must
carefully lower the units or sections to ground level, not dropping them or
throwing them; and
(C) May leave
asbestos-containing materials in large facility components such as reactor
vessels, large tanks and steam generators, but excluding beams, if the
following requirements are met:
(i) The
component is removed, transported, stored, disposed of, or reused without
disturbing or damaging the asbestos-containing material;
(ii) The component is encased in leak-tight
wrapping; and
(iii) The leak-tight
wrapping is labeled according to OAR
340-248-0280(2)(b)
during all loading and unloading operations and during storage.
(e) For friable
asbestos materials being abated:
(A)
Adequately wet the materials to ensure that they remain wet until they are
disposed of in accordance with OAR
340-248-0280;
(B) Carefully lower the materials to the
floor, not dropping or throwing them;
(C) With DEQ's prior written approval,
transport the materials to the ground via dust-tight chutes or containers if
they have been removed or stripped above ground level and were not removed as
units or in sections;
(D) Enclose
the area where friable asbestos materials are to be abated with a negative
pressure enclosure prior to and during abatement unless DEQ grants written
approval for an alternative;
(E)
Install a minimum of one viewing window in all enclosures, including negative
pressure enclosures, in accordance with the following:
(i) Each viewing window must be a minimum of
two feet by two feet and be made of a material that will allow a clear view
inside the enclosure; and
(ii) For
large enclosures, including negative pressure enclosures, install one viewing
window for every 5,000 square feet of area when spatially feasible;
and
(F) A negative
pressure enclosure is not required for abatement of friable asbestos-containing
material when:
(i) Abating
asbestos-containing petroleum-based roofing products or cement asbestos
roofing; or
(ii) Abating a total
project amount of asbestos-containing material that may be contained in a
single glove bag.
(f) A person who demolishes a facility under
an order of the State of Oregon or a local governmental agency, issued because
the facility is structurally unsound and in danger of imminent collapse must
comply with the following:
(A) Obtain DEQ's
written approval for an ordered demolition procedure before that demolition
takes place;
(B) Send a copy of the
order and an asbestos abatement project notification (as described in OAR
340-248-0260) to DEQ before
starting demolition work;
(C) Keep
a copy of the order, DEQ's approval, and the notification form at the
demolition site during all phases of demolition until final disposal of the
project waste at a permitted disposal site; and
(D) Keep asbestos-containing materials and
asbestos-containing waste materials adequately wet during demolition and comply
with the disposal requirements set forth in OAR
340-248-0280.
(g) A person performing asbestos
abatement may not use mechanical equipment to remove asbestos containing
material outside of a full negative pressure enclosure without prior written
approval from DEQ.
(h) Visible
emissions are not allowed during an asbestos abatement activity, except within
a negative air pressure enclosure.
(i) An exhaust ventilation and collection
system, negative air machine, or vacuuming equipment used during an asbestos
abatement project must be equipped with a HEPA filter or other filter of equal
or greater collection efficiency and must be sealed with a 6 mil plastic or
equivalent when not in use.
(j) DEQ
may approve, on a case-by-case basis, requests to use an alternative to the
requirements contained in this rule. The person performing the asbestos
abatement project must submit a written description of the proposed alternative
and demonstrate to DEQ's satisfaction that the proposed alternative provides
public health protection equivalent to the protection that would be provided by
the specific requirement, or that such level of protection cannot be obtained
for the asbestos abatement project.
(k) Final Air Clearance Sampling Requirements
apply to projects involving more than 160 square feet or 260 linear feet of
asbestos-containing material. Before the negative pressure enclosure around
such an area is removed, the person performing the abatement must have at least
one air sample collected. All samples collected that document that the air
inside the negative pressure enclosure has no more than 0.01 fibers per cubic
centimeter of air. DEQ may grant a waiver to this section or exceptions to the
following requirements upon receiving an advanced written request:
(A) The air clearance samples must be
collected and analyzed by a party who is National Institute of Occupational
Safety and Health (NIOSH) 582 certified and financially independent from the
person performing the asbestos abatement project, other than receiving
compensation for undertaking the specific sampling and analysis required in
this paragraph;
(B) Before final
air clearance sampling is performed the following must be completed:
(i) All visible asbestos-containing material
and asbestos-containing waste material must be removed and properly packaged
and stored according to the requirements of this division;
(ii) The air and surfaces within the negative
pressure enclosure must be sprayed with an encapsulant prior to air clearance
sampling;
(iii) Air sampling may
start when the encapsulant has settled sufficiently so that the filter of the
sample is not clogged by airborne encapsulant; and
(iv) Air filtration units must remain on
during the air-monitoring period;
(C) Air clearance sampling inside negative
pressure enclosure areas must be aggressive and comply with the following
procedures:
(i) Immediately before starting
the sampling pumps, direct exhaust from a minimum one horse power forced air
blower against all walls, ceilings, floors, ledges, and other surfaces in the
negative pressure enclosure;
(ii)
Then place stationary fans in locations that will not interfere with air
monitoring equipment and direct the fans toward the ceiling. Use one fan per
10,000 cubic feet of room space;
(iii) Start sampling pumps and sample an
adequate volume of air to detect concentrations of 0.01 fibers of asbestos per
cubic centimeter according to NIOSH 7400 method;
(iv) When sampling is completed turn off the
pump and then the fan(s); and
(v)
As an alternative the air clearance sample analysis may be performed according
to Transmission Electron Microscopy Analytical Methods prescribed by 40 C.F.R.
763, Appendix A to Subpart E (Interim Transmission Electron Microscopy
Analytical Methods); and
(D) The person performing an asbestos
abatement project must submit the final air clearance sample results to DEQ on
a DEQ form and include all third-party air clearance analysis reports. The
clearance results must be received by DEQ within 30 days after the completion
date of the asbestos abatement project.
