Executive Summary

ATC has completed the pre-renovation limited asbestos, lead based paint (LBP), and lead dust sampling of various buildings at the VA Medical Center property located at 5500 Armstrong Road, Battle Creek, Michigan. ATC understands these structures will be renovated in connection with a HVAC upgrade.

Asbestos Survey

An ATC licensed asbestos inspector performed an asbestos containing materials (ACM) survey of the subject buildings in accordance with Part 602, the Michigan Occupational Safety and Health Administration (MIOSHA)

Asbestos Standard for Construction, and NESHAP (Title 40, Part 61, Subpart M) requirements. ATC was provided specific rooms and areas of each of the buildings to inspect. The survey identified ACM and presumed asbestos containing materials (PACM).

One hundred twenty (120) samples, taken from forty (40) homogenous areas, were collected and submitted for laboratory analysis by polarized-light microscopy. Based on the laboratory results, two of the materials sampled were found to be ACM.

Section 61.145(c) of the Asbestos NESHAP requires that each owner or operator of a demolition or renovation activity involving regulated asbestos containing materials (RACM), remove all such material from a facility being demolished or renovated before any activity begins that would break up, dislodge, or similarly disturb the material or preclude access to the material for subsequent removal.

Michigan Public Act 135, P.A. 1986, as amended requires a Licensed Asbestos Abatement Contractor to perform abatement of ACM and PACM in accordance with Part 602 (MIOSHA Asbestos Standard for Construction) and

NESHAP (Title 40, Part 61, Subpart M) requirements.

The National Emission Standards for Hazardous Air Pollutants (NESHAP) 40 CFR Part 61, Subpart M requires licensed asbestos abatement contractor to submit notification of abatement ten (10) working days prior to renovation or demolition activity for asbestos materials when quantities of Regulated Asbestos-Containing

Materials (RACM) are greater than two hundred and sixty (260) linear feet or one hundred and sixty (160) square feet.

The Department of Licensing and Regulatory Affairs (Michigan OSHA) through P.A 135 of 1986 requires a licensed asbestos abatement contractor to submit notification for asbestos abatement ten (10) calendar days prior to the start of renovation or demolition activity that will disturb greater than ten (10) linear or fifteen (15) square feet.

Lead Containing Paint

Paint chip samples were collected and analyzed for total lead content. A total of nineteen (19) paint samples were submitted for analysis by USEPA Method SW846-7420 for lead. The results of laboratory testing during the limited lead-based paint sampling conducted at the property indicate that eight (8) of the samples contained levels of lead greater than the method detection limit of 0.01%.

ATC recommends that the project specifications include a section on worker protection according to the OSHA regulations at 29 CFR 1926.62 and that a contractor knowledgeable (does not require licensing) in lead paint removal and worker protection be specified for this portion of the project.

ATC shall not be responsible for identifying all lead-containing materials located behind walls and /or columns, beneath flooring, above solid ceilings, underground or any other inaccessible areas. If material is found during the course of demolition that is not listed in the report the material should be assumed to be lead containing until it can be sampled and analyzed at a laboratory.

Lead Dust Wipes

Dust wipe sampling was conducted using “Lead Wipes” to sample representative surface areas measuring twelve inches by twelve inches within the ductwork in various locations throughout the buildings. A total of seven (7) paint samples were submitted for analysis. The results of laboratory testing during the lead wipe sampling conducted at the property indicate that lead levels in the sampled locations ranged from 80.8 to 253.3 µg/ft2.

3 Limited Pre-Renovation Asbestos Survey

ATC representative, Mr. Robert N. VanDyke, P.E., conducted the pre-renovation asbestos inspection of the areas identified at the property buildings from April 1 through April 11, 2019. Mr. VanDyke is a State of Michigan Certified

Asbestos Inspector’s (Certification No. A19528). Site sketches identifying sampling locations and general building details are included as Appendix D. The property buildings were visually inspected for the presence of building materials that are suspected to contain asbestos. Bulk samples of suspect ACMs were collected and placed into individual containers for transport to a National Voluntary Lab Accreditation Program (NVLAP)-accredited laboratory for analysis. Materials typically known as non-asbestos items (i.e. fibrous glass, foam rubber, wood, etc.) were not sampled. The asbestos inspection consisted of the following three basic procedures:

> Conducting a visual inspection of the structures;

> Identifying homogeneous areas (HAs) of suspect surfacing, thermal system insulation, and miscellaneous materials; and

> Sampling accessible, friable and non-friable suspect materials.

3.1 Homogeneous Areas

Prior to collecting any samples, homogenous areas (HAs) were identified. A homogeneous sampling area can be described as one or more areas of material that are similar in appearance and texture and that have the same apparent installation date, appearance and function. Actual number of samples collected from each homogeneous sampling area may vary, based on the type of material and professional opinion of the inspector.

3.2 Hazard Assessment Factors

From the list of suspect homogeneous areas, a physical assessment was performed for each material on the list.

A physical assessment includes evaluating the condition, assessing the potential for disturbance, and determining the friability of each material. By definition, "friable" materials are those that can be crumbled or reduced to powder by hand pressure when dry. Each material identified was further classified into one of three categories: surfacing materials, thermal systems insulation (TSI) and miscellaneous materials. Each of the three categories have specific sampling requirements, outlined below.

> Surfacing Materials: Refers to spray-applied or troweled surfaces such as plaster ceilings and walls, fireproofing, textured paints, textured plasters, and spray-applied acoustical surfaces.

> Thermal System Insulation: Refers to insulation used to inhibit heat gain or loss on pipes, boilers, tanks, ducts, and various other building components.

> Miscellaneous Materials: Refers to friable and non-friable products and materials that do not fit in any of the above two categories such as resilient floor covering, baseboards, mastics, adhesives, roofing material, caulking, glazing, and siding. This category also contains wallboard and ceiling tile.

All materials were assessed related to their condition in one of the three categories: good (intact), fair (damaged) or poor (significantly damaged) per Title 40 Code of Federal Regulations Part 763. Material with localized, significant damage was also assessed as poor.

3.3 Laboratory Analytical Methodology

Bulk samples were analyzed by APEX Research Inc, 11054 Hi Tech Drive, Whitmore Lake, Michigan, using polarized-light microscopy (PLM) and dispersion staining (Method Reference: 40 CFR Part 763, Volume 47, No.

103, May 27, 1982 pg. 23376). This laboratory participates in the National Voluntary Laboratory Accreditation

Program (NVLAP #102118-0), a quality assurance program for PLM analysis, and is accredited by the National

Institute of Standards and Technology (NIST) as well as accreditation requirements under 15 CFR Part 25.

Copies of the laboratory analytical report and corresponding chain-of-custody forms are included in Appendix A.

Positive sample results are reported in percent asbestos by volume of the sample and the type of asbestos material

April 22, 2019 ATC 8 within the sample. Other common non-asbestos components may also be noted on the analytical reports.

Inspector and laboratory accreditations are provided in Appendix E.

3.4 Sampling Results

Bulk samples were collected from the site building and analyzed by polarized light microscopy (PLM), EPA Method

600/R-93/116. Two (2) of the materials sampled were found to contain concentrations of asbestos greater than

1%.

4 Limited Lead-Based Paint Sampling

A Limited Lead-Based Paint (LBP) survey was conducted of readily accessible interior building areas by ATC representative Mr. Robert N. VanDyke, P.E. The LBP survey was completed from April 1 through April 11, 2019 and included physical sampling of paint coatings that were deemed representative of the predominant paint coatings observed within the building. LBP, as defined by the EPA is paint with a lead concentration of greater than or equal to 0.5% lead by weight.

Paint chip samples were collected from homogeneous interior/exterior areas and submitted to APEX Research

Inc, 11054 Hi Tech Drive, Whitmore Lake, Michigan for lead analysis. Bulk samples were analysed using the

Environmental Protection Agency's Test Method SW 846 -3050B and 7420 using Flame AAS to determine lead concentration in percent (%) by weight.

The following table provides a summary of the sampled paint from the Site buildings:

Table 4-1 LBP Sampling Results

5 Limited Lead Wipe Sampling

Dust wipe sampling was conducted using “Lead Wipes” to sample representative surface areas measuring twelve inches by twelve inches within the ductwork in various locations throughout the buildings. A total of seven (7) dust samples were submitted for analysis to APEX Research Inc, 11054 Hi Tech Drive, Whitmore Lake, Michigan for lead analysis.

The following table provides a summary of the wipe samples from the Site buildings:

Table 5-1 Lead Wipe Sampling Results

Sample ID Area (ft2) Sample Location Lead Content (µg/ft2)

01-LW-002-A 1.0 Bldg 2 - Attic 168.0

02-LW-002-A 1.0 Bldg 2 - Basement 153.3

03-LW-012-A 1.0 Bldg 12 - 1st Floor 253.3

04-LW-012-A 1.0 Bldg 12 - 2nd Floor 159.0

05-LW-012-A 1.0 Bldg 12 - Attic 226.0

06-LW-136-A 1.0 Bldg 136 - Penthouse 216.0

07-LW-136-A 1.0 Bldg 136 - Ground Floor 80.8

The results of the lead sampling in dust indicate levels of lead were detected above the detection limit. OSHA does not have a standard for levels of lead in dust, however, the OSHA Lead in Construction standard requires workers who may disturb lead surfaces to be trained in accordance with the standard. In addition, workers should be notified of the potential lead in dust or paint hazards, and to ensure work that will disturb the materials that contain lead are done so with appropriate work practices, PPE, and personal hygiene requirements as stated in the standard.

Laboratory results of the wipe sampling are included in Appendix C.

April 22, 2019 ATC 12

6 Conclusions and Recommendations

6.1 Asbestos-Containing Materials

The results of laboratory testing during the pre-renovation asbestos survey conducted at the property indicate that two (2) of the materials sampled were found to contain asbestos.

Non-friable ACM’s shall not be subjected to abrasion, grinding, sanding or any other processes during demolition activities which will render these non-friable materials friable.

Based on the NESHAP (National Emission Standards for Hazardous Air Pollutants) non-friable Category I ACM and Category I non-friable PACM roofing materials that are asphalt/tar based can be demolished with a building so long as it is in good condition and will not be cut, pounded, sanded, or grinded during demolition, and that measures are taken to ensure that it does not become friable, at which point will be considered RACM. This material can also be disposed off-site in a Class III, construction and demolition (C&D) debris, landfill within the framework of local/state regulations. In addition all roofing materials shall not be recycled if they contain Category

I ACM.

6.2 Lead-Based Paint

The results of laboratory testing during the limited lead-based paint sampling conducted at the property indicate that lead was not detected above the EPA established threshold of 0.5%.

The results of the lead in dust sampling in the ductwork indicate that lead is present in the dust above the detection limit.

The presence of LBP and lead dust requires, under OSHA 1926.62 requirements, that the contractor performing demolition, surface preparation, and other activities that impact or potentially impact on the LBP coating systems and dust, evaluate potential worker exposures to airborne lead. This evaluation can be based, for the specific activities denoted in 1926.62, on objective data obtained by the contractor on other, similar, worksites within the prior calendar year or, the Contractor should conduct a negative exposure assessment during work activities to ensure they are below the applicable Action Level for airborne lead. . In addition, LBP and LBP coated waste and construction debris must be evaluated and, on a case-by-case basis depending on this evaluation, quantitative analysis be performed on these waste steams to ensure compliance with EPA waste disposal regulations.

The presence of LBP does not, in itself, trigger regulatory compliance actions. However, when these materials are disturbed, the requirements of OSHA (1926.1101) and EPA may become operative. Appropriate actions in terms of removal methods, emissions control, worker protection, and waste disposal should be considered by the general contractor and applicable subcontractors while completing demolition activities.
