RESULTS OF LOWER PLATFORM TESTING, DAYS 2 (4/22/14) & 3 (4/23/14)

• The assembly of the lower platform was completed per instructions above.

• Minor modifications were required in order to make assembly complete: handrail mounting pins (POST MK-35) needed to have a taper (instead of champher) ground on to ends of them to aid in line up into mating part. Parts had been champhered. Also the two small access doors were ground to fit mating cutouts in floor. (Misc. protrusions, burrs and weld slag).

• Platform was then leveled using angle finder and compound level by adjusting torsion bars.

• Once leveled, three individuals from Mohawk (total weight 700 lbs.) climbed out on the platform through the access door and sat/stood on platform for 15 mins.

• Platform end did sink approximately 2" from level as there was rotational movement at the bolting plates, Mk-26 R & L and MK-26 lower plate where the plates were bolted together.

• COE, Sharon and Larry E from Mohawk came up with a concept of welding stop pads on the upper brackets in order to stop the movement and end drop of platform.

• This was done and drop was reduced to 1" as platform was retested with 700 lbs., three employees.

• The above was conducted with the COE and Skytek personnel observing test.

• Additional tab was welded on the vertical plane of each bracket and was retested using the same above protocol in the COE's and Skytek's presence on 4/24/14. Test was successful.

RESULTS OF PLATFORM LADDER TESTING, DAY 2 (4/22/14)

• Ladder was assembled and bolted together.

• Ladder was raised to a leaning position against the inside of the building wall.

• Mohawk's Dan Coven weighing 250 lbs. climbed the ladder 2/3 of the way up and secured ladder rung to vertical beam of building for safety.

• Dan Coven came down, and then went up the ladder to approximately the third rung from the top to prove accessibility.

• After wards, Dan came down and a 250 lb. weight was attached approximately % of the way up on the ladder by strap and left there for 20 minutes.

• The above was conducted with the COE and Skytek personnel observing test.

M PONTOOM PONTOO

NOTE: Float test was performed at Haynes Boat Launch Park due to the accessibility problems at the original site (Beltline Hwy location).

RESULTS OF FLOAT TESTING, DAY4 (4/24/14):

• Only one rope was required as a tether line held by Mohawk employee on boat ramp.

• Each pontoon was lifted into the water by two other Mohawk employees wearing life preservers, but still being able to stand on the submerged part of the boat ramp's corrugated sloped surface.

• Time of water entry was documented and testing began.

o Pontoon was stabilized in the river and a measurement/reading from the inner section of pontoon was taken from the top of pontoon to the water line.

o The small outer end of the pontoon was noted by approximation how deep it was submerged in the river, that reading/determination was also recorded.

o Two 5 gallon buckets loaded with metal parts each weighing 125 Lbs. was strapped on top of the pontoon with a bucket one each side of pontoon. Total weight was 250 lbs.

o Weight was positioned approximately 3-1/2" from the center line of the outer hole on the inner lifting lug in order to keep the pontoon floating level. That dimension was recorded.

o The same procedure was again used to record the buoyancy of the pontoon by measuring the height from top of inner pontoon to waterline and recording.

o The small end was also viewed and approximation/determination of submerged depth was recorded in the same manner previously to adding weight.

• At 10 minutes of the pontoon being in the water, the pontoon was then pulled out of the water and placed on the bed of the Mohawk construction truck.

• The drain plug was removed and the pontoon was tiled toward plug in order to measure how much water came out of each pontoon. That amount was recorded.

• The COE and Skytek personnel observed process.

The above procedure was repeated for all six pontoons. COE and Skytek were furnished with a copy of all recorded documentation of the testing.

• Each pontoon was filled with water.

• Each pontoon was observed and inspected for leakage around each beam pinning location.

• Minor leakage was observed on two pontoons.

• The COE and Skytek personnel observed process.

PAINTING OF PONTOON TOP SURFACE, DAY 5 (4/25/14).

RESULTS OF PAINTING PONTOON SURFACE:

• Cleaning and prepping of the top surface of pontoons was performed.

• ColvaBond wash primer was applied sufficiently to the top surface of the pontoons per manufactures recommendations.

• Rodda Non-Skid paint went was applied sufficiently to top surface of pontoons per manufacturer recommendations.

WORK ON, OVER, OR NEAR WATER

1. PURPOSE:

Work over or near water occurs often at a hydroelectric facility, adding risk to the work performed by Corps or contractor employees. This Policy examines the ways workers are exposed to this risk, and prescribes the precautions to be taken. Prior to beginning work over or near water, personnel shall have already prepared an Activity Hazard Analysis, attended a pre-work meeting, and contacted the Control Room for coordination and implementation.

This policy details the following procedures:

a) Boat Restricted Zone (BRZ)

b) Water Rescue

c) Boat and Operator Qualifications

d) Fall Protection

2. SCOPE:

This policy applies to all Corps and non-Corps personnel.

3. REFERENCES:

c) JD Standing Order III, Safe Clearance Procedure

d) 29 CFR, Parts 1910 General Industry; 1918 Longshoring; & 1926, Construction

4. DEFINITIONS:

Activity Hazard Analysis - The AHA will define the activities being performed and identify the sequence of work, the specific hazards anticipated, the control measures to be implemented, and the personal protective equipment (PPE) to be used.

Boat Restricted Zone - The BRZ at the project is comprised of Outer and Inner Zones. Zone 1 (Outer) is defined by large orange and white signs placed at the shores; and Zone 2 (Inner) is defined as the area close enough to a dam structure (< 600 ft.) as to require reconfiguration of water control equipment to avoid dangerous flow conditions to the boats. Zone 2, therefore, requires compliance with the Safe Clearance Procedures before entering the BRZ. Any person wishing to enter the BRZ must follow the procedures outlined in PARAGRAPH 5, below. Permission to enter the BRZ may be withdrawn due to operational concerns at a moment’s notice by the Operating Manager or his/her representative. See Figures 1 and 2 on pages 10 and 11.

Fall Restraint System - Body harness, lanyard and connecting hardware, which can be attached to a solid anchorage point, thereby precluding a fall hazard. EM 385-1-1, Sections 16.T.10 and Appendix Q (definitions).

Immediately available - The lifesaving skiff or rescue boat must be in the water and all systems tested and operational.

Lifesaving Skiff - A vessel used for the rescue of a worker who has fallen from work over water that satisfies the requirements of EM 385-1-1, Section 5.K. As defined in Section 5.I., in locations where the waters are rough, swift, or where manually operated boats are not practical, a powered boat suitable for the waters shall be provided and equipped for lifesaving.

Near water – When a worker is performing work from a shoreline or other surface essentially at the same elevation as the water surface, where a drowning hazard exists.

On water – When a worker is performing work out of a boat or barge, exposed to the risk of falling less than six feet vertically into the surrounding water.

Over water - Work performed from a dam deck, structure, or equipment, where a fall (of more than six feet) would result in entering the river, pool or fishway.

Personal Fall Arrest System (PFA) - A body harness, connecting hardware, lanyard, and lifeline or self-retracting lifeline. EM 385-1-1, Sections 05.H and 21.C. For PFA with retrieval; the system includes a winch (usually hand-operated) by which another worker can hoist a fallen worker to safety.

Personal Floatation Device (PFD) - USCG-approved Type I, III or Type V (no inflatable’s), International Orange/Red color, with reflective stripe and PFD light. EM 385-1-1, Section 05.J.

Rescue & Work Boat - Vessels 26’ or Less: A vessel satisfying the following requirements:

powered by two motors, each capable of driving the boat upstream while fully loaded, at twice the swiftest water velocity encountered inside the Boat Restricted Zone.

Vessels greater than 26’ shall be sufficiently powered to travel against current while loaded to full capacity with enough freeboard to safely carry its equipment and personnel.

5. BOAT RESTRICTED ZONE PROCEDURES

RATIONALE

Work-related freshwater boating has hazards recognized by most workers However, work near a dam structure can present additional hazards—sudden, large, natural or man-made, often without warning, and deadly—that originate from flow or environmental changes not evident to the boat’s crew. Two scenarios exist where work occurs within the BRZ: working over or near water; and working from a workboat. In both scenarios, a properly staffed and equipped rescue boat shall be immediately available (see definitions for requirements).

PROCEDURE

a. Anyone who intends to enter the Boat Restricted Zone of John Day or Willow Creek project for performing work must apply for permission in writing, at least two weeks in advance of the anticipated entry date. The request must include a schedule, a written work plan, and an Activity Hazard Analysis.

The Operations Manager or his/her designate must approve the request prior to entry.

NOTE: for operational emergencies e.g., debris in forebay obstructing a fishway, the Control Room Operator will call out a trained retrieval crew of project employees (see below) to remove the hazard to operations. The responding crew will follow a pre-approved Activity Hazard Analysis; the two-week prior request notification is waived for such emergencies. The crew will conduct a pre-work meeting in the Control Room.

b. A pre-work safety meeting will be conducted at the facility prior to the anticipated work. The work leader or supervisor of the boat crew must attend this meeting, and must provide evidence there that the requirements of this Policy have been satisfied.

c. When applicable and practicable, the Control Room Operator will configure dam equipment to minimize flows in the work area. This equipment will be “tagged out” via the dam’s Safe Clearance Procedure, thus preventing operation of the equipment during the work. No boat may enter the work area until approval is given by the Control Room Operator. The Control Room Operator has the right to deny entry, if any condition would threaten the safety of the boat crew. The boat crew shall also call the Control Room upon leaving the BRZ.

d. Clear lines of radio communication between each boat and the dam Control Room shall be agreed upon during the pre-work meeting, and established before the boat(s) enter the BRZ.

PERSONNEL

a. The operator of any boat entering the BRZ must provide proof of qualification as a trained, experienced operator of the boat being piloted (provide documentation at the pre-job meeting). A list of qualified project vessel operators is included as Appendix A.

b. The crew of the workboat shall include an operator who will not engage in any other work while piloting the boat. When a workboat is securely tied off in the area of operations, the operator may conduct other activities that do not interfere with the primary responsibility of piloting the boat.

c. “NOTE”At least one of the workboat crew and one of the rescue boat crew, other than the operator, must be trained in CPR, first aid, and water rescue procedures.

EQUIPMENT

a. Work boats and rescue boats must meet U.S. Coast Guard safety standards for all boat operating conditions. In addition, each boat shall meet current State and Federal requirements.

b. Work boats and rescue boats must be equipped with the following (EM 385-1-1, 19A):

1. Fire extinguisher--for boats less than 26-ft in length, one 1-A:10-B:C extinguisher; for boats greater than 26-ft in length, two 1-A:10-B:C extinguishers.

2. Personal floatation devices (PFD) for the maximum crew listed for the boat.

3. Running and anchor lights

4. An audible warning device capable of alerting rescue personnel anywhere within the BRZ

5. A marine band radio capable of communicating with the Control Room on Channel 14

6. An approved ring buoy with a minimum seventy-foot throw line (buoyant rope required)

7. An adequately sized towrope

8. A spotlight or acceptable visual distress signal

6. WATER RESCUE

RATIONALE

When a worker faces the hazard of falling in water, Corps safety requirements and project policy necessitate rescue readiness. This procedure defines the requirements for providing rescue actions and post-rescue care of a worker exposed to water immersion.

REQUIREMENTS

a. Minimum of two crew members dedicated strictly to rescue operations. One operator exclusively dedicated as a boat operator and another rescue crew member trained in cold-water rescue and certified to perform First Aid/CPR.

b. Crew members of a rescue boat or life-saving skiff must be trained in rescue and post-rescue care procedures. Training for project employees will be made available by project management.

Contractors shall include in the Activity Hazard Analysis, procedures for cold-water rescue and post-rescue care.

c. Rescue response is intended for protection of project workers performing assigned duties—not as first responders to other agencies or to the public. However, if an overboard event occurs in the immediate vicinity of a project work site, where a non-project individual is in imminent danger of drowning, then the project safety boat and crew may respond, in the spirit of the State’s Good Samaritan laws. In keeping with project’s partnership with local law enforcement agencies, we will provide rescue efforts as practicable, when requested by the Sheriff’s office or similar agency.

d. When the rescue boat responds to an overboard event, a crewmember shall notify the appropriate Control Room of the in-progress rescue. The Control Room Operator will call the entities listed below for continued care of the rescued worker.

- Mid-Columbia Medical Center (541) 296 -1111

- Klickitat Valley Hospital (509) 773 - 4022

- Providence / Hood River Hospital (541) 386 – 3911

d. “WARNING” During BRZ operations, if the rescue boat becomes unavailable, all work will cease.

e. The Columbia River water temperature is below 70 F year-round. Worker rescue from the river becomes, therefore, a “cold-water rescue.” Project employees who become rescue crewmembers will be trained in, and will use, cold-water rescue and care techniques for all such events.

7. BOAT AND OPERATOR QUALIFICATIONS

RATIONALE

Project policy requires that personnel operating watercraft less than 26-feet in length shall be trained, tested and licensed in accordance with ER 385-1-91, 19.A.02, this document and other applicable regulations. Employees who operate watercraft will do so in a safe manner in accordance with recognized Federal, state and local laws and standards.

REQUIREMENTS

PERSONNEL (Reference EM 385-1-1, Section 19.A.02).

a. Government operators shall be licensed or certified in accordance with ER 385-1-19.A.02. Officers and crew shall be qualified and documented by the designated project authority.

b. Non-Government operators and crew shall be qualified as evidenced by a Boater Education Card or by letter from the employer with a current, valid USCG license.

c. In accordance with new guidance from the Oregon State Marine Board:

By January 1, 2003, all individuals age 16 up to and including age 30 are required to possess a Boater Education Card to operate a motorboat having more than 10 horsepower.

By January 1, 2004, all individuals age 16 up to and including age 40 are required to possess a Boater Education Card to operate a motorboat having more than 10 horsepower.

8. FALL PROTECTION

RATIONALE

There are several scenarios of dam work during which personnel may fall into the water. These different scenarios demand different methods of fall protection, and are covered by different regulations. Below are example scenarios, with appropriate references and the required precautions.

POSSIBLE SCENARIOS & REQUIRED SAFETY PRECAUTIONS:

* Work from a work platform suspended by mobile crane:

Requirements-- (ref. EM 385-1-1, Section 16.T.10&21.N; OSHA 1926.550(g)(3)(i)(F) 1926.106)

(1) OSHA-compliant work platform

(2) Inspected and load-tested mobile crane

(3) PFD in place of PFA

(4) Rescue boat immediately available

(5) For swift current or turbulent water, reconfigure plant equipment to stop the flow. If the current cannot be substantially reduced, then alternative means of access must be utilized. A live- boom-supported work platform may not be used in this circumstance. (booms in which lowering is controlled by a brake without aid from other devices which slow the lowering speeds)

SPECIAL EXCEPTION: When a diver is to perform underwater work and will access the water with a work platform, then no lifesaving skiff is required. However, if the diver’s tender or standby diver will remain in the work platform above water, then that condition will be considered work over water, and a lifesaving skiff (or rescue boat for BRZ work) will be required.

* Work from a suspended scaffold, supported by a portable frame:

Requirements--(ref. EM 385-1-1, Section 16.T & 21.N)

(1) OSHA-compliant work platform

(2) Inspected and tested hoist/frame system, secured by locking wheels or anchored to deck

(3) Fall arrest system

(4) For swift current or turbulent water, reconfigure plant equipment to stop the flow. If the current cannot be substantially reduced, then a second fall arrest system with retrieval capability shall be attached to each worker.

* Work from the dam structure, or stationary, rigid frame (without guardrail or safety net):

Requirements--(ref. EM 385-1-1, Sections 21.A. and 22.A)

(1) Fall arrest system

(2) A co-worker/observer, for emergency retrieval if needed

(3) a ring buoy with a minimum length of 90 ft.

(4) For swift current or turbulent water, reconfigure plant equipment to stop the flow. If the current cannot be substantially reduced use a second fall arrest system with built-in retrieval, in lieu of a lifesaving skiff (or rescue boat for BRZ work).

* Work from the water surface (work boat, barge, etc.):

Requirements—(ref.’s noted)

(1) Within the Boat Restricted Zone: see Paragraph 5 above

(2) Outside the Boat Restricted Zone: see EM 385-1-1, Section 19, “Floating Plant and Marine Activities”.

* Work near the water surface at the same elevation (i.e., shoreline):

Requirements--(ref. EM 385-1-1, Section 5.J)

(1) PFD

(2) Communication with Control Room

(3) Co-worker within clear sight.

(4) Ring Buoy with rope (see rope requirements above)

SPECIAL EXCEPTIONS: (1) Walkway access onto a boat dock does not require PFD use; however, work on a dock will be treated as “work near the water surface.” (2) Where a dam deck has a guardrail on one side, and personnel can traverse the deck without approaching the unprotected edge, no PFD is required. However, if work will occur near the edge, or if an unprotected portion of travel exists, then a PFD is required.

1.0 BACKGROUND INFORMATION AND SCOPE OF WORK

Quaternary Resource Investigations, LLC (QRI) was contracted by the U.S. Army Corps of Engineers (USACE), Portland District, to perform a Hazardous Material Testing and Assessment at the John Day Dam Powerhouse at 304 W. 2nd, Rufus, Oregon 97050. QRI was awarded Delivery Order W9127N22F0022 under USACE Contract GS-10F-105BA. This report documents the absence and/or presence of asbestos-containing material (ACM) for four shut down hydropower units within the John Day Dam Powerhouse and within the breathable air within four operational hydropower units. The results of this survey provide a representative baseline regarding the hazardous nature and condition of the ACM that will require proper management by personnel conducting renovations on all 16 hydropower units within the Powerhouse. Non-destructive bulk samples were collected where possible from four hydropower units on maintenance shut down (units #7, #6, #10, and #11) and air samples were collected from hydropower units #8, #9, #1, and #3, respectively, while operational and two ambient background samples were collected from within the Powerhouse and outside the Powerhouse.

Asbestos has been used in a variety of applications and products to include thermal insulation for heating/cooling systems, as surfacing treatments and fireproofing, and miscellaneous applications such as gaskets, flooring, electrical insulation, roofing components, etc. On July 12, 1989, EPA issued a final rule banning most asbestos-containing products. In 1991, this regulation was overturned by the Fifth Circuit Court of Appeals in New Orleans. As a result of the Court's decision, the 1989 asbestos regulation only bans new uses of asbestos in products that would be initiated for the first time after 1989 and bans the following specific asbestos-containing products: flooring felt, rollboard, and corrugated, commercial, or specialty paper. In hydropower plants, asbestos was used as insulation for generators and turbines and sprayed on piping and conduits. By the mid-20th century, asbestos was used in fire-retardant coatings, concrete, bricks, pipes, gaskets, pipe insulation, ceiling insulation, fireproof drywall, flooring, and roofing. Asbestos may also be present in generator brakes and control cables.

Asbestos is a naturally occurring mineral which can form long, thin fibers. Inhalation of asbestos fibers can cause adverse health effects resulting in asbestosis, a scarring of the lung; and diseases including mesothelioma, a cancer of the lining of the chest or lining of the abdominal wall. Asbestos-containing materials can be categorized as nonfriable or friable.

Friable ACM can be crushed to powder by hand pressure while nonfriable material cannot be crushed by hand pressure. Fibers from friable ACM can be readily released to the air;

however, nonfriable ACM may also release fibers if damaged or disturbed.

All asbestos-related sampling activities conducted for this project followed the standards of the EPA (40 Code of Federal Regulations [CFR] Part 763, Subpart E), the National Emission Standards for Hazardous Air Pollutants (NESHAP), Subpart M, the National Emission Standard for Asbestos, and the Asbestos Hazard Emergency Response Act (AHERA) of 1986, Oregon state regulations; and applicable U.S. Army regulations and guidance.

Regulation of asbestos exposure in the occupational setting is the responsibility of the Occupational Safety and Health Administration (OSHA).

This asbestos survey was conducted on July 26-28, 2022, in a manner consistent with the level of care and skill ordinarily exercised by members of the profession. The results, findings, A24-6

3.5 Transmission Electron Microscopy Method for Asbestos in Air Transmission electron microscopy (TEM) technology was used for the analysis of the samples in this project due to the need for accuracy and because the area where the samples were collected are within an operational air housing where ACM is known to exist. The phase contrast microscopy (PCM) method of analysis can count fibers but cannot positively identify the fibers as asbestos. Using PCM analysis, fibers of a certain width to length ratio are assumed to be asbestos fibers and counted accordingly. In comparison, TEM sampling methods use a higher magnification, thereby allowing smaller fibers to be detected and this allows the technician to positively differentiate between an asbestos fiber or a non-asbestos fiber with less chance of false positive results.

TEM analysis requires the collection of airborne fibers using calibrated sampling pumps with mixed-cellulose ester (MCE) filters and analysis by TEM. A known volume of air is drawn through a 25-millimeter (mm) diameter cassette containing an MCE filter. The cassette is equipped with an electrically conductive 50-mm extension cowl. The sampling time and rate are chosen to give a fiber density of between 100 fibers/mm2 to 1,300 fibers/mm2 on the filter.

A portion of the sample fiber is cleared and prepared for asbestos fiber counting by PCM at a magnification of 400X for accuracy.

3.6 Polarized Light Microscopy Method for Bulk Asbestos Samples

Polarized light microscopy (PLM) is the technique most often employed for the analysis of bulk building materials. This light microscopy technique utilizes the unique features of polarized light to observe mineral-specific optical properties. In this manner, PLM can differentiate asbestos from non-asbestos fibers and further classify the various species that compose the asbestos mineral family. Moreover, the technique records the identity of the non-asbestos fibrous component of each bulk building material sample.

Point counting will be employed to more accurately determine the percent of asbestos that is in the material being sampled if fibers are present and the results are inconclusive.

Additionally, samples analyzed via PLM frequently are determined to contain “trace” amounts of asbestos usually written as <1% asbestos. Any sample determined to contain <1% asbestos must be point counted to prove it contains less than 1% asbestos otherwise, it assumed to be positive regardless of the PLM results.

Typical materials that are candidates for point count analysis include drywall-joint compound, ceiling or wall texture, hard plaster, etc. The main purpose to point count material is to determine if a material contains less than 1% asbestos since materials containing ≤1% are by definition “non-asbestos containing.” If point counting is not used, many materials could be mistakenly considered to contain >1% asbestos thus meeting the definition of an asbestos-containing material. This mistaken assumption could lead to an expensive asbestos management or remediation projects that could otherwise be avoided.

With the point count procedure, for each layer of material to be point counted, eight mounts are made by dispersing eight pinches of a sample in a suitable fluid. A reticule is placed on the eyepiece of the microscope that superimposes a grid of points over the field of view. Fifty non-empty points are examined for each mount yielding 400 points, some of which would be identified as asbestos and the rest as non-asbestos material. A simple calculation gives the percentage of asbestos; four points in 400 would be 1%.

4.0 SURVEY METHODOLOGY

QRI conducted a representative asbestos survey on four of the 16 Powerhouse hydropower units within the John Day Dam complex which were shut down for maintenance. Utilizing non-destructive methods, representative samples of suspect material were collected homogeneous areas, documented for location, quantity, and condition; and submitted to an accredited laboratory for analysis.

4.1 Procedure Description

The sampling protocol employed for this project was consistent with the sampling protocol contained in 40 CFR 763. The following describes the bulk and air sampling activities conducted at the John Day Dam Powerhouse from July 26-28, 2022:

Conducted an initial pre-work safety briefing with the John Day Dam personnel and USACE team prior to the first day of work and conducted daily tailgate safety briefings.;

Obtained from John Day personnel the list of four generators identified for asbestos inspection and sampling and the four generators identified for air sampling;

Conducted a visual inspection of the generators slated for surveying and testing to identify homogenous areas of friable and nonfriable suspect ACM;

Assumed and documented inaccessible areas of suspect ACM;

Assessed location, quantity, and condition of friable and nonfriable suspect ACM;

Determined area airflow, dust-laden areas, calibrated and set up air sampling pumps to conduct air monitoring;

Decontaminated sampling instruments between samples;

Utilized nitrile gloves during sampling. Gloves were changed between samples to avoid cross-contamination and were disposed of as contaminated waste;

Double bagged and sealed samples in accordance with AHERA/OSHA requirements.

Samples were sent for ACM analysis to the 3rd party testing facility (EMSL) approved by the NVLAP;

Requested five-day turnaround for analytic results; and Prepared final report showing sample locations, type, (thermal, miscellaneous, surfacing; friable, and nonfriable), locations, and quantity of ACM, date of collection, photos, and map of positive ACM locations.

Bulk sampling was conducted as follows:

Determined homogeneous areas of suspect material for sampling;

Used a clean and dry, small sealable sample bag to contain the sample;

Before taking the bulk sample, the material to be sampled was wetted with a fine mist of water containing a few drops of detergent to minimize the potential release of asbestos fibers. Additionally, a plastic sheet was placed under the sample site to catch any material which may fall;

A clean knife or T-Core sampling device was used to remove a small piece of material about two square inches and placed in a labeled zip-lock bag;

Ensured any paint or…
