NCPD-MT 56(55), 4199-055-000, Billings Bypass, Parcel 1

The above-mentioned property is located approximately 0.3 miles NE of I-90 and Johnson Lane in Billings, MT.

The property address is as follows 1207 Johnson Ln, Billings, MT 59101. There are 3 possible ways to access the driveway: access off N Frontage Rd and turn left on Sannon Blvd (driveway to the left), Coulson Rd and Sannon Blvd (driveway will be to the right) or access off Coulson Rd between Johnson Ln and Sannon Blvd (see aerial-street view attachment for directions).

1207 Johnson Ln has 2 structures that need to be demolished. Those structures are as follows:

Structure 1 is a 2-story, 3 bed, 2 bath house built in 1953. First floor is 888 sq. ft. with 162 sq. ft. enclosed porch, and the basement is 1,050 sq. ft. with a concrete foundation.

Structure 2 is a 1,344 sq. ft. pole frame garage built in 1960 with metal exterior walls, no insulation and gravel floor.

To comply with the Migratory Bird Treaty Act, any tree or shrub removal shall occur from August 15 to April 15 (outside of the nesting season). If contractor has any questions regarding this Act or tree removal, please contact Bill Semmens, (406) 444-7227, with MDT Environmental Services Bureau.

The Contractor is required to permanently disconnect, cap and abandon the water wells that are located behind Structure 2 and the well that is located near the northeast corner of the property in the field. If possible, leave the well in front of Structure 2 on the southwest corner of the structure, the contractor will need to disconnect this well from Structure 1 but do not cap or abandon, unless the well is in the way of the demolition.

The Contractor must pump, remove, and properly dispose of the septic system associated with structure 1. The septic system (no permit) appears to be located northwest of Structure 1 as shown on the attachment and the drainfield is north-northeast of the domicile.

MDT has contacted Yellowstone Valley Electric Co-op about the disconnecting of electricity from both Structures and has removed the meter. The Contractor may contact Yellowstone Valley Electric Co-op at (406) 348-3411 with any additional questions regarding the utilities.

The Contractor is ultimately responsible for verifying all the necessary utilities connected to the structures have been disconnected before work begins.

OUTBUILDING

No suspect ACMs were identified during our inspection. Therefore, no samples were collected.

LBP INSPECTION

No painted components were tested for LBP as part of this inspection.

EPA has stated that whole building demolition debris is considered a non-hazardous waste regarding lead. Further analysis for lead in the waste stream by TCLP analysis is not needed. Tetra Tech recommends that the waste created from whole building demolition be considered non-hazardous regarding lead, and the building components can be disposed of at an authorized C&D landfill.

MERCURY-CONTAINING COMPONENT INSPECTION

The visual inspection of mercury-containing equipment, including compact fluorescent lamps, fluorescent U-tubes, fluorescent lamps, linear fluorescent lamps, mercury vapor lamps, metal halide lamps, sodium vapor lamps, thermostats, as well as miscellaneous components (if present), was conducted during the inspection. The final portion of the inspection consisted of Tetra Tech personnel opening and disassembling the component to observe whether the

4 January 9, 2026 component had labels indicating mercury content. Where applicable, the components’ manufacturing information was compared against a listing of mercury-containing components provided by the EPA.

During the visual inspection, no mercury-containing components were identified in the former residence and outbuilding. Consequently, there are no recommendations or required actions, or remediation needed at this time.

PCB-CONTAINING COMPONENT INSPECTION

The visual inspection of PCB-containing equipment, including air conditioners, capacitors, equipment with electrical motors, freezers, furnace blower motors, hydraulic equipment, light ballasts, switches, and transformers, as well as miscellaneous components (if present), was conducted during the inspection. The final portion of the inspection consisted of Tetra Tech personnel opening and disassembling the component to observe whether the component had labels indicating PCB content. Where applicable, the components’ manufacturing information was compared against a listing of PCB-containing components provided by the EPA.

During the visual inspection, no PCB-containing components were identified in the former residence and outbuilding.

Consequently, there are no recommendations or required actions, or remediation needed at this time.

CFC-CONTAINING COMPONENT INSPECTION

The visual inspection of CFC-containing equipment, including air conditioners, capacitors, equipment with electrical motors, freezers, as well as miscellaneous components (if present), was conducted during the inspection. The final portion of the inspection consisted of Tetra Tech personnel opening and disassembling the component to observe whether the component had labels indicating CFC content.

LIMITATIONS

The purpose of this pre-demolition hazardous materials inspection is to identify suspect ACMs, mercury-containing components, PCB-containing components, CFC-containing components, and other hazardous materials through reasonable testing and visual observations. However, no inspection can guarantee that all hazardous materials present at the site will be detected. This assessment was limited to visible and accessible materials and components. Hidden materials and components may exist within walls, above ceilings, or in other concealed spaces. Completion of this inspection does not constitute a warranty or guarantee that hazardous materials are absent from the site.

Our findings and recommendations are intended solely for the Montana Department of Transportation and may not be suitable for other parties. Any use or reliance on this document by others is at their own risk. This report may not be altered or reproduced without written approval from Tetra Tech. The opinions provided are based on the scope of services requested and the site conditions observed during the inspection. They may not apply to future conditions that were not evaluated as part of this assessment.

AIHA LAP, LLC Laboratory #102929

A "trace asbestos" will be reported if the analyst observes far less than 1% asbestos. CA Labs defines "trace asbestos" as a few fibers detected by the analyst in several preparations and will indicate as such under these circumstances.

Since allowable variation in quantification of samples close to 1% is high, <1% may be reported. Such results are ideal for point counting, and the technique is mandatory for friable samples (NESHAP, Nov. 1990 and clarification letter 8 May 1991) under 1% percent asbestos or "trace asbestos".

In order to make all initial PLM reports issued from CA Labs NESHAP compliant, all <1% asbestos results (except floor tiles) will be point counted at no additional charge.

CA Labs is accredited by the National Voluntary Accreditation Program (NVLAP) for selected test methods for airborne fiber analysis (TEM), and for bulk asbestos fiber analysis (PLM). CA Labs is also accredited by AIHA LAP, LLC. in the PLM asbestos field of testing for Industrial Hygiene. All analysts have completed college courses or hold a degree in a natural science (geology, biology, or environmental science). Recognition by a state professional board in one these disciplines is preferred, but not required. Extensive in-house training programs are used to augment the educational background of the analyst. The Laboratory Director and Quality Manager have received supplemental McCrone Research training for asbestos identification. Analysis performed at Crisp Analytical Labs, LLC 1929 Old Denton Road Carrollton, TX 75006

Dallas NVLAP Lab Code 200349-0 TEM/PLM TDSHS 30-0235

Summary of polarized light microscopy (PLM / Stereomicroscopy bulk asbestos analysis) using the methods described in 40CFR Part 763

Appendix E to Subpart E (Interim and EPA 600 / R-93 / 116 (Improved). The sample is first viewed with the aid of a stereomicroscope. Numerous liquid slide preparations are created for analysis under the polarized microscope where identifications and quantifications are preformed. Calibrated liquid refractive oils are used as liquid mouting medium. These oils are used for identification (dispersion staining). A calibrated visual estimation is reported, should any asbestiform mineral be present. Other techniques such as acid washing are used in conjugation with refractive oils for detection of smaller quantities of asbestos. All asbestos percentages are based on calibrated visual estimation traceable to NIST standards for regulated asbestos. Traceability to measurement and calibration is achieved by using known amounts and types of asbestos from standards where analyst and laboratory accuracy are measured. As little as 0.001% asbestos can be detected in favorable samples, while detection in unfavorable samples may approach the detection limit of 0.50% (well above the laboratory definition of trace).

Vermiculite containing samples may contain trace amounts of actinolite/tremolite. When not detected by PLM, these samples should be analyzed using TEM methods and / or water separation techniques. Suspected actinolite/vermiculite presence will be indicated through the sample comment section of this report.

Fibrous talc containing samples may contain a regulated asbestos fiber known as anthophyllite. Under certain conditions the same fiber may actually contain both talc and anthophyllite (a phenomenon called intergrowth). Again, TEM detection methods are recommended. CA Labs PLM report comments will denote suspected amounts of asbestiform anthophyllite with talc, where further analysis is recommended.

Some samples (floor tiles, surfacings, etc.) may contain fibers too small to be detectable by PLM analysis and should be analyzed by TEM bulk protocols.
