1.0 INTRODUCTION
Under an Interagency Agreement with the U.S. Environmental Protection Agency (USEPA), the U.S.
Army Corps of Engineers (USAGE), Tulsa District, contracted Shaw Environmental, Inc. (Shaw) under
Task Order 0110 of the Total Environmental Restoration Contract (TERC) No. DACA56-94-D-0020, to
develop a project design for asbestos abatement at the Oklahoma Refining Company (ORC) Site, Cyril,
Caddo County, Oklahoma. The asbestos abatement work is being performed as part of a time-critical
removal action at the site. The asbestos abatement work will comply with the existing statutes and
regulations governing the removal and disposal of friable asbestos-containing materials (ACM) in
facilities within the State of Oklahoma. This design provides a prudent course of action for the handling
of asbestos in the best interests of the facility, employees, management, and the general public.
The ORC Site is located at 2 West Main Street, Cyril, Oklahoma. As shown in Figure 1-1, the site is on
the east side of the town of Cyril, south of Highway 277, and is bisected by a railway. An aerial view
photograph of the site is presented in Figure 1-2. A plan view of the process area and tank farm is
presented in Figure 1-3.
Asbestos abatement at the ORC Site will be performed as described in this project design by a company
subcontracted to Shaw. The asbestos abatement subcontractor is responsible for verifying the quantities
of asbestos at the site. A mandatory walkthrough is required for this project. At this walkthrough, the
subcontractor is responsible for determining the following:
• the conditions affecting the work, including physical conditions of the site that may bear
upon site access, handling and storage of tools and materials, access to water, electric, or
other utilities, or that may otherwise affect performance of required activities.
• the character and quantity of surface and substrate materials associated with asbestos, or
obstacles to be encountered insofar as this information is reasonably ascertainable from an
inspection of the site, including exploratory work performed by the USEPA or a designated
consultant, and information presented in drawings and specifications included with this
contract. Failure by the asbestos abatement subcontractor to acquaint himself with
responsibility for estimating properly the difficulty or cost of successfully performing the
work shall not be grounds for additional cost. The USEPA is not responsible for the
conclusions or interpretations made by the asbestos abatement subcontractor on the basis of
the information made available by USEPA.
No bids for asbestos abatement will be accepted by Shaw from an asbestos abatement subcontractor who
has not inspected the job site either in person or through a qualified designated representative.

Final Project Design for Asbestos Abatement
2.0 PROJECT SCOPE
The project includes the removal of friable ACM to support the decontamination/demolition of the ORC
Site. Known and accessible friable ACM will be removed within each refinery unit prior to the
dismantling/demolishing and complete purging of the structures in that unit. When general demolition
begins, an asbestos abatement crew shall be on site to remove previously undiscovered asbestos materials
that are exposed during the demolition procedures. The major features of the asbestos abatement scope
are summarized in items A through J below.
A. Asbestos Materials
From April to July 1992, Asbestos Analytics, Inc. performed a survey for ACM at the ORC Site. A total
of 240 bulk samples were collected and analyzed. The results of those analyses revealed that ACM was
present in the following categories and amounts:
Square Linear
Asbestos-Containing Material Feet Feet Fittings
Thermal Insulation 61,230 53,805 3,130
Surfacing Materials 12,000 0 0
Miscellaneous Materials 14,707 48 0
Total 87,937 54,853 3,130
Thermal insulation includes friable insulation on piping and equipment, such as boilers, lines and fittings,
stacks, towers, heat exchangers, etc.
Surfacing materials include sprayed-on/trowelled-on insulation.
The miscellaneous materials include non-friable asbestos in the form of floor tiles, transite, linoleum,
gasket material, etc. Though not regulated under Oklahoma Administrative Code (OAC) 380:50, non-
friable asbestos (e.g., transite) removal procedures are being presented as a courtesy to the Oklahoma
Department of Labor (DOL). Also, while gasket material is non-friable if unused, it may become friable
when used or damaged.
The asbestos survey data from the 1992 report are included in Appendix A, and a summary of asbestos
quantities is presented in Appendix B. Details of the survey (including photographs of each sample
location) are documented in the Asbestos Survey Report for Cyril Petrochemical Corporation, 2 West
Main, Cyril, Oklahoma (Asbestos Analytics, Inc, 1992). A copy of the document will be maintained on
site throughout the duration of the asbestos abatement work. Additionally, any analytical results collected
to further delineate the extent of friable ACM will be maintained on site. The USEPA is prepared to
collect as many as 400 additional samples for this purpose.
B. Project Type - Asbestos
C. Type of Asbestos: Up to 90% chrysotile and up to 70% amosite (see Appendix A for Asbestos
Survey Data).
D. Number of Full Containments - One: the warehouse welding shop (if addressed). Other abatement
work is largely outdoors, and glovebag and wind wall wet removal techniques will be used. The
glovebag technique will be used to remove friable ACM from piping within buildings.

Final Project Design for Asbestos Abatement
E. Number of Crew Shifts: There will be one shift - 0800 to 1700 hours Monday through Friday.
Multiple crews will work simultaneously at different parts of the site during that one shift.
F. Sequencing of Work
1. Sequencing shall be determined by mutual agreement among USEPA, USAGE, the
abatement subcontractor, and Shaw.
2. Some variation may take place as work progresses. Oklahoma DOL will receive advance
notice of changes or requests for waivers.
3. Work will be performed simultaneously by multiple crews at different areas of the site during
the project.
G. Special Removal Procedures (Variances)
The following variances are being requested:
A variance is being requested from the procedures described in OAC 380:50-17-4 (7) (8) (Preparation of
Asbestos Abatement Work Areas) to allow the use of alternate methods in regulated areas for the
removal of the asbestos without establishing a full containment with polyethylene floors/walls. The
refinery has been standing idle for a number of years and is to be decontaminated and demolished. The
ACM over the years had become damaged, with the majority of the material at elevated levels (>6.0
feet). Alternate procedures are listed in this design.
A variance is being requested from the procedures described in OAC 380:50-11-2 (Clean-Test
Requirements) to allow requirements for clearance sampling to be waived as described in OAC 380:50-
17-14 (3) (Demolition Procedures). This variance is requested on the following grounds:
1. The facility is industrial
2. The entire site is scheduled for demolition
3. The abatement is primarily outdoors
Visual inspection and lockdown of surfaces in regulated areas will serve as final clearance criteria.
A variance is being requested regarding lockdown at the fluidized catalytic cracking unit (the converter
section) and the isostripper tower (see Section 5.2d). For each of these two structures, it is requested
that the application of lockdown be waived until the unit is on the ground. At that time, lockdown would
be applied. This is requested due to the height of the structures. Applying lockdown while still vertical
might result in paint overspray on passing traffic or neighboring properties.
H. Wetting Methods
Amended water shall be used to wet materials as they are removed.

Final Project Design for Asbestos Abatement
I. Non-Asbestos Abatement Demolition
• A competent person will be on site during the various phases of demolition to observe the
areas for possible unidentified friable ACM. Qualified workers will sample and/or abate
ACM if unidentified ACM is discovered during non-asbestos demolition activities.
• Demolition material shall be wet, as necessary, to comply with National Emission Standards
for Hazardous Air Pollutants (NESHAP) requirements.
It is not the intent of this design to include inaccessible ACM (e.g., behind walls, elevated areas).
These materials represent less than 1% by volume. As the demolition contractor moves the material,
a visible search shall be performed to identify ACM. If ACM is found, it will be removed prior to
proceeding with the demolition.
J. Project Phases
The asbestos abatement work will be performed in two phases: (1) process area and (2) tank farm.
Within the process area, abatement will generally proceed from unit to unit (e.g., vacuum distillation
to fluidized catalytic cracking unit to reformer, etc.), and from north to south.
