G2 was contracted by OED to perform a limited building inspection for ACM and LBP. The survey was conducted at the OED Roseburg Facility, located at 846 Pine Street, in Roseburg, Oregon.

The scope of the inspection was limited to readily accessible interior, exterior and roofing materials in anticipation of the upcoming renovation activities, as specified by Ron Adkins with OED. The sampling was conducted to represent all suspect materials within the scope of work.

The scope of services was to perform a visual and tactile inspection, and identify the presence, quantity and location of the accessible ACM, within the area(s) of the scope of work. All identified accessible suspect materials were sampled. The building was occupied at the time of the survey, therefore, destructive sampling techniques were not utilized to gain access to potentially hidden materials such as within wall cavities or other interstitial spaces.

The LBP inspection was performed in accordance with the U.S. Environmental Protection Agency Renovation, Repair and Painting Rule (EPA RRP) because it was conducted by a licensed LBP inspector using documented methodologies, such as those in Housing and Urban Development (HUD) Guidelines Chapter 7 (2012 Edition), and the EPA RRP guidelines.

Readings of the lead content of painted surfaces throughout the areas within the scope of work were collected using an X-Ray Fluorescence device. The readings were taken from the predominant accessible interior and exterior paint films including surfaces coated with shellac, varnish, stain, etc., in order to provide a general indication of the distribution of lead. All Federal and State regulations governing the inspection of LBP were followed.

Results of the inspection have determined that asbestos is present in the following suspect materials sampled as part of this limited survey:

The types of components listed in the following table indicate the presence of lead at or above the EPA RRP and HUD Guidelines action level. The EPA and HUD definition of “positive” LBP is lead equal to or greater than 1.0 mg/cm2. Additional details including reading number, floor, substrate, side, color and lead content details are located in the XRF Readings Table found in Appendix C.

Readings in the table noted as LBP, are paint films with lead concentrations at or above 1.0 mg/cm2. Readings in the table noted as Positive, are non-painted surfaces, such as ceramic tile, with lead concentrations at or above 1.0 mg/cm2

Per HUD guidelines, for each era of construction to be inspected, all testing combinations in each room equivalent were identified and tested by XRF. A testing combination is characterized by the room equivalent, the component type, and the substrate. A room equivalent is an identifiable part of a building (room, exterior, foyer, etc.). Painted surfaces include any surface coated with paint, shellac, varnish, stain, paint covered by wallpaper, or any other coating.

According to HUD Guidelines Chapter 7, if one testing combination (i.e. window, door) is positive for lead in an interior or exterior room equivalent, then all other similar testing combinations in those areas are also assumed to be positive for lead.

The XRF testing was conducted using an XRF lead paint analyzer. A surface-by-surface visual assessment of the painted and/or finished surfaces was conducted to determine which lead-coated surfaces/components are deteriorated at or above de minimis levels, specifically, the EPA’s minor repair and maintenance activities thresholds (40 CFR § 745.83). The EPA de minimis thresholds apply to work that disrupts: (a) 6 square feet or less of painted surface per room for interior activities; or (b) 20 square feet or less of painted surface for exterior activities; provided that none of the work practices prohibited or restricted by 40 CFR § 745.85(a)(3) were used and where the work does not involve window replacement or demolition of painted surface areas.

EPA regulations define deteriorated paint as, “any interior or exterior paint or other coating that is peeling, chipping, chalking or cracking, or any paint or coating located on an interior or exterior surface or fixture that is otherwise damaged or separated from the substrate" (40 CFR § 745.63).

Results of the survey have determined that multiple interior and exterior materials are ACMs.

All materials were observed to be in good to fair condition at the time of the survey.

If any untested suspect materials are encountered during renovation activities, they should be assumed to be ACM and not disturbed, unless sampling and analysis of the materials proves otherwise.

Friability is determined by whether a material can be crumbled, pulverized or reduced to a powder by pressure of an ordinary human hand. The friability of materials listed in this report are based on the present state and actual conditions of the materials observed at the time of G2’s survey.

Materials listed as non-friable can become friable through impact or damage.

All identified and presumed ACM must be removed by a licensed asbestos abatement contractor, or other certified individual, prior to impact if they are to be disturbed during renovation activities. ACM remaining in the building should be managed in good condition, under an Operations and Maintenance Plan, and checked regularly for damage.

OR-OSHA requires a variety of actions when ACM is present in a commercial structure. These include labelling, warning signs, hazard communication and periodic inspections. All of the requirements of a building owner/operator with regard to asbestos can be found in Oregon Administrative Rules (OAR) 437, Division 2.

Any ACM likely to be disturbed during renovation or demolition activities, other than by incidental contact with no generation of debris related to other construction activities, should be abated by a licensed asbestos abatement contractor. Any activities conducted where the primary object of the activity is the removal of ACM must be conducted by a licensed asbestos abatement contractor or other properly trained individuals.

The National Emissions Standards for Hazardous Air Pollutants (NESHAPs) requires that all Regulated Asbestos-Containing Materials (RACMs) be removed from a building prior to demolition.

Recommended Response Actions

Asbestos-Containing Materials (ACM)

Any building material which contains asbestos in an amount greater than 1% is considered an ACM by the United States Environmental Protection Agency (EPA) and Occupational Safety and Health Administration (OSHA), and by the State of Oregon Department of Environmental Quality (DEQ) and the Oregon Occupational Safety and Health Division (OR-OSHA).

Page of 9 12

G2 Consultants | www.g2ci.com | 888-998-4224 http://www.g2ci.com https://osha.oregon.gov/OSHARules/div2/div2Z-1001-asbestos.pdf https://osha.oregon.gov/OSHARules/div2/div2Z-1001-asbestos.pdf

No materials were identified during this survey that contained 1% or less asbestos.

Many of the engineering controls and work practices required by the EPA and OSHA are applicable only to materials that contain greater than 1% asbestos. However, OSHA has established work practice requirements and prohibitions that apply when asbestos in any quantity is present, and/or whenever worker exposure exceeds the PEL regardless of the amount of asbestos in the materials involved. Applicable requirements for materials that contain 1% or less asbestos can be found in the OSHA Asbestos Construction Standard 29 CFR 1926.1101.

G2 has determined that LBP is present on the interior of the building that is equal to or above the concentration of 1.0 mg/cm2. The LBP films were observed to be in “intact” condition at the time of the inspection. Lead above the 1.0 mg/cm2 threshold was also identified in the glazing of various ceramic tile and enamel components within the building.

Lead-containing paint (LCP), paint films with lead concentrations greater than zero but less than

1.0 mg/cm2, may be present on other painted surfaces. The presence/absence of LCP cannot be confirmed via XRF analysis.

LBP and LCP films could create lead dust or lead contaminated soil hazards if the paint is turned to dust by abrasion, scraping or sanding. If conditions of intact paint surfaces become destabilized, these conditions will need to be addressed. All paint films in poor condition must be stabilized if the structure is to be demolished. If any construction or modernization work is done on the premises, this report should be given to the contractor(s). The Occupational Safety and Health Administration (OSHA) and Oregon OSHA (OR-OSHA) have requirements for employees working with or around LBP and LCP.

Contractors and other personnel who may impact these materials should be informed of the results of this inspection. LBP is a common cause of lead poisoning in children and represents a threat to the health and welfare of the occupants. Where economically feasible, it is our recommendation that all components that tested positive, and any similar untested components, be considered lead-laden, and lead-safe procedures is incorporated into any overall renovation and maintenance strategy in order to reduce the potential for contamination and/or exposure. Safe methods include:

containing any work area to prevent dispersal of lead dust and chips, wet sanding and scraping at a minimum; collecting all paint chips and debris and, properly disposing of them.

Details of the locations and lead content for all of the readings can be found in Appendix C: XRF Readings Table.

If additional painted surfaces are discovered that were not tested as part of this inspection, or that are expected to be impacted as part of any renovation or demolition work, they should be presumed LBP until tested to show otherwise.

Asbestos-Containing Materials - 1% Asbestos or Less

Any building material which contains asbestos in an amount of 1% or less is considered asbestos-containing by OSHA and OR-OSHA. Although these materials are not considered ACMs, workers must be protected from exposure to asbestos, regardless of the percentage.

Page of 10 12

A risk assessment has not been conducted to evaluate potential lead hazards present at the building and surrounding soil as part of this scope of work.

The field work was conducted using industry best practices. Samples of representative accessible suspect materials within the scope of work were collected during the course of the inspection.

Materials were sampled according to homogeneous groupings using the Asbestos Hazard Emergency Response Act (AHERA) sampling guidelines.

Asbestos samples were collected in such a manner as to minimize release of the material into the surroundings. Sample number, material description, sample location and material location were recorded at the time of sampling. Each sample was placed in a sample container labeled with a unique sample number and submitted to a National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratory, for analysis under chain of custody documentation. Samples were analyzed in accordance with EPA Method 600/R-93-116, using PLM with dispersion staining and using visual area estimation to determine percent asbestos content. This method allows for the identification of the primary types of asbestos used in building materials. The lower limit of detection for this method is one percent. Samples containing one percent or less asbestos by PLM with visual area estimation are reported as “Trace”.

All testing of suspect LBP was conducted utilizing a SciAps X-ray fluorescence LBP analyzer, Model X550Pb (Rh) bearing Serial #01583. The device uses a rhodium X-ray fluorescence tube as opposed to a radioactive source. G2 followed the Performance Characteristics Sheets (PCS) for the specific X-Ray fluorescence instrument used during the LBP evaluation of the property. The XRF PCS is presented in Appendix D. The instrument was calibrated to the manufacturer's specifications and was also periodically verified against the National Institute of Standards and Testing (NIST) Standard Reference Material (SRM) 2579 lead film (1.0 mg/cm2).

The calibration of the instrument is conducted in accordance with the PCS for this instrument.

These instruments are calibrated using a calibration standard block of known lead content. If for any reason the instruments do not maintain a consistent calibration reading within the manufacturer’s standards for performance on the calibration block supplied by the manufacturer, manufacturer’s recommendations are used to bring the instrument into calibration. If the instrument cannot be brought back into calibration, it is taken off the site and sent back to the manufacturer for repair and/or re-calibration.

Wall “A” in each room is the wall where the front entrance door opening is located (or aligned with street). Going clockwise and facing Wall “A,” Wall “B” will always be to your right, Wall “C” directly to the rear and Wall “D” to the left. Doors, windows and closets may be designated as left, center or right depending on their location on the wall. Doors, windows, and closets are designated as left, center or right depending on their location on the wall.

All individuals who performed this XRF testing and visual assessment have EPA and/or state licenses as Lead Inspector/Risk Assessors and have been trained in the use, calibration and maintenance of the XRF, along with the principles of radiation safety, in accordance with the work practices of 40 CFR 745, section 227, for states and Native American tribal groups.

G2 has performed this inspection in accordance with best industry methods and practices of the profession, and consistent with the level of care and skill ordinarily exercised by reputable environmental consultants under similar circumstances and conditions. The observations contained within this assessment are based upon site conditions readily accessible at the time of the site inspection. No other representation, guarantee or warranty, express or implied, is included or intended in this hazardous materials survey report. If any untested suspect materials are encountered during demolition activities, they should be assumed to be ACM and not disturbed, unless sampling and analysis of the materials proves otherwise.

The LBP portion of the inspection was planned, developed, and implemented based on G2’s professional experience in performing LBP inspections. G2 performed an inspection for lead-containing paint of the predominant painted surfaces in order to provide a general indication of the distribution of lead for demolition purposes. G2 utilized state-of-the-art practices and techniques in accordance with regulatory standards while performing this inspection. A copy of personnel and company certifications has been provided in Appendix E. G2’s evaluation of the painted surfaces identified during this inspection is based on conditions observed at the time of the inspection. G2 cannot be responsible for changing conditions that may alter the relative exposure risk for future changes in accepted methodology.

The owner is responsible to convey information regarding identified lead content to inhabitants, contractors, etc. expected to potentially be exposed. G2 recommends that both the contractor and the owner keep the records for three years.

This report consists of a visual survey, and XRF analysis of the readily accessible areas of this building and tested components. The presence or absence of LBP or LBP hazards applies only to the tested or assessed surfaces on the date(s) of the field visit and it should be understood that conditions may change due to deterioration or maintenance. The results and material conditions noted within this report were accurate at the time of the evaluation and in no way reflect the conditions at the property after the date of the evaluation.

As with all environmental investigations, this inspection is limited to the defined scope and does not purport to set forth all hazards, nor indicate that other hazards do not exist.

Approved By: Andrea Berrios Disclaimer:

The results in this report only apply to the samples as received.

NOB samples are tested as a preliminary analysis. We highly recommend for Negative NOB samples resulting in less than 1% Asbestos to be verified by TEM or Point Analysis.

Inhomogeneous samples are separated into homogeneous subsamples and analyzed individually. NAD means no asbestos fibers were detected. When detected the minimum detection and reporting limit is less than 1% unless point counting is performed. Floor tile samples may contain large amounts of interference material and it is recommended that the sample be analyzed by gravimetric point count analysis to lower the detection limit and to aid in asbestos identification.

Guidelines for Interpretation:

Any opinions/interpretations expressed in this report are outside the scope of this laboratory's accreditation. Interpretation of the data and information within this document is left to the company, consultant, and/or persons who conducted the fieldwork. A material is considered regulated asbestos containing material (ACM) where the asbestos content is determined to be one percent or greater. Several organizations, including the

NOB samples are tested as a preliminary analysis. We highly recommend for Negative NOB samples resulting in less than 1% Asbestos to be verified by TEM or Point Analysis.

Inhomogeneous samples are separated into homogeneous subsamples and analyzed individually. NAD means no asbestos fibers were detected. When detected the minimum detection and reporting limit is less than 1% unless point counting is performed. Floor tile samples may contain large amounts of interference material and it is recommended that the sample be analyzed by gravimetric point count analysis to lower the detection limit and to aid in asbestos identification.
