1.0 INTRODUCTION

Terracon Consultants, Inc. (Terracon) conducted a pre-demolition asbestos survey and hazardous building materials assessment of the building located at 32660 Little Sand Bay Road, Bayfield, Wisconsin. The survey was conducted on July 10, 2015 by a Wisconsin-certified asbestos inspector in general accordance with our cost proposal emailed to Mr. Kerry Newman on May 29, 2015 and our work plan dated June 30, 2015. In addition, per your July 9, 2015 voicemail request, Terracon developed and implemented a limited plan for sampling lead in soil samples collected from around the building on July 11, 2015.

The interior and exterior building components were surveyed, and homogeneous areas of suspect asbestos-containing materials (ACM) were visually identified and documented.

Although reasonable effort was made to survey accessible suspect materials, additional suspect but un-sampled materials could be located in walls, in voids or in other concealed areas.

Suspect ACM samples were collected in general accordance with the sampling protocols outlined in United States Environmental Protection Agency (USEPA) 40 Code of Federal Regulations (CFR) Part 763 Subpart E 763, known as the Asbestos Hazard Emergency Response Act (AHERA). Samples were delivered to an accredited laboratory for analysis by Polarized Light Microscopy (PLM). In addition, in accordance with the work plan, five blind duplicate samples were submitted for analysis.

We understand this asbestos survey was requested due to the planned demolition of the LSB VC building to satisfy requirements of the USEPA 40 CFR Part 61, Subpart M, the National Emission Standards for Hazardous Air Pollutants (NESHAP).

In conjunction with the asbestos survey, a visual assessment was performed to identify and quantify other hazardous materials, including lead, mold, fluorescent light tubes, mercury, and bio-hazards. Where observed, these items were documented and quantified.

The limitations of liability defined in Terracon’s Agreement for Services is the aggregate limit of Terracon’s liability to SFS Architecture.

2.0 BUILDING DESCRIPTION

The subject building is an approximately 3,834-square-feet two-story building with partial basement and crawlspace. The building was reportedly constructed around 1940, with significant renovations since that time. The basement walls are a combination of stone/mortar and block wall. The building is wood framed and wood siding. Interior areas of the building are finished with drywall, carpet, wood flooring, ceramic floor tiles, and ceiling tiles. The main floor serves as the visitor center and ranger office. The second floor appears to have been originally designed as living quarters that are no longer in use. The area is used for storage. The roof is divided into two sections; the north side was recently replaced with a new asphalt composite shingle roofing and the south side is a flat roof covered with a membrane-type roofing system.

3.0 FIELD ACTIVITIES

The survey was conducted by Elizabeth M Newbold, a Wisconsin-licensed asbestos inspector (License No. AII-184404). A copy of Elizabeth M Newbold’s asbestos inspector license is included in Appendix E. The survey was conducted in general accordance with the sample collection protocols established in USEPA 40 CFR Part 763 Subpart E 763.86, AHERA. A summary of survey activities is provided below.

3.1 Visual Assessment

Survey activities were initiated with visual observation of the interior and exterior of the building to identify homogeneous areas of suspect ACM. A homogeneous area (HA) consists of building materials that appear similar throughout in terms of color and texture with consideration given to the date of application. Interior assessment was conducted in visually accessible areas of the building proposed for demolition.

Terracon did not conduct destructive investigation of doors in the building to determine if the doors were insulated with suspect ACM. However, the doors appeared to be wood. Terracon observed older electrical fixtures, junction boxes, and fiber-coated wiring. These were assumed to be asbestos-containing as they were live and could not be sampled.

3.2 Physical Assessment

A physical assessment of each HA of suspect ACM was conducted to assess the friability and condition of the materials. A friable material is defined by the USEPA as a material which can be

July 28, 2015 Terracon Project No. 58157036

Responsive Resourceful Reliable 3 crumbled, pulverized or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials.

3.3 Sample Collection

Based on results of the visual observation, bulk samples of suspect ACM were collected in general accordance with USEPA AHERA sampling protocols. Samples of suspect materials were collected from randomly selected locations in each homogeneous area. Bulk samples were collected using wet methods as applicable to reduce the potential for fiber release.

Samples were placed in sealable containers and labeled with unique sample numbers using an indelible marker.

The selection of sample locations and frequency of sampling were based on Terracon’s observations and the assumption that like materials in the same area are homogeneous in content.

Terracon collected 110 bulk samples from 36 homogeneous areas of suspect ACM. A summary of suspect ACM samples collected during the survey is included as Appendix B.

3.4 Sample Analysis

Bulk samples were submitted under chain of custody to Steve Moody Micro Systems (SMMS) of Farmers Branch, Texas for analysis by polarized light microscopy with dispersion staining techniques per USEPA methodology 600/R-93/116. The percentage of asbestos, where applicable, was determined by microscopic visual estimation. Steve Moody Micro Systems (SMMS) is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP) Accreditation No. 102056-0.

4.0 REGULATORY OVERVIEW

The asbestos NESHAP (40 CFR Part 61, Subpart M) regulates asbestos fiber emissions and asbestos waste disposal practices. The asbestos NESHAP regulation also requires the identification and classification of existing ACM according to friability prior to demolition or renovation activity. Friable ACM is a material containing more than 1% asbestos that, when dry, can be crumbled, pulverized or reduced to powder by hand pressure. All friable ACM is considered regulated asbestos containing material (RACM).

The asbestos NESHAP regulation classifies ACM as either RACM, Category I non-friable ACM or Category II non-friable ACM. RACM includes all friable ACM, along with Category I and Category II non-friable ACM that has become friable, will be or has been subjected to sanding, grinding, cutting or abrading, or ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder in the course of renovation or demolition activity.

July 28, 2015 Terracon Project No. 58157036

Responsive Resourceful Reliable 4

Category I non-friable ACM are exclusively asbestos-containing packings, gaskets, resilient floor coverings, resilient floor covering mastics and asphalt roofing products that contain more than 1% asbestos. Category II non-friable ACM are all other non-friable materials other than Category I non-friable ACM that contain more than 1% asbestos. Category II non-friable ACM generally includes but is not limited to cementitious material such as: cement pipes, cement siding, cement panels, glazing, mortar, and grouts.

The OSHA standards 29 CFR 1910.1001 and 29 CFR 1926.1101, regulate employee exposure to asbestos. The OSHA standards require that employee exposure to airborne asbestos fibers be maintained at or below 0.1 fibers per cubic centimeter of air (0.1 f/cc) as an eight hour time weighted average (TWA), and not exceed 1.0 fibers per cubic centimeter of air (1.0 f/cc) over a 30 minute time period known as an excursion limit (EL). The TWA and EL are known as OSHA’s permissible exposure limits (PELs). The OSHA standard classifies construction and maintenance activities which could disturb ACM, and specifies work practices and precautions which employers must follow when engaging in each class of regulated work. Building owners are required to maintain buildings and equipment in a safe operating condition, including the repair, removal, encapsulation or enclosure of damaged ACMs.

5.0 HAZARDOUS BUILDING MATERIALS

In accordance with the work plan, a visual assessment was performed to identify and quantify other hazardous materials, including: lead, mold, fluorescent light tubes, mercury, and bio-hazards. Materials such as mercury, chlorofluorocarbons (CFCs), radioactive sources, batteries, polychlorinated biphenyls (PCBs), and lead-based paint (LBP) can be found in building components. These materials are considered environmental hazards and require special precautions if they will be removed in association with the demolition to prevent their entry into the environment. On occasion, manufacturers will label the equipment regarding the presence or absence of a hazardous material.

5.1 PCBs

PCBs range from clear, oily liquids to white or yellowish waxy solids, depending on the degree of chlorination. They are stable, thermoplastic and non-flammable materials that found chief use in insulation for electric cables and wires in the production of electric condensers and additives for extreme pressure lubricants. Light ballasts can contain about one ounce of the toxic substance. The transportation, disposal and spill clean-up of PCB-containing ballasts is regulated by the Toxic Substances Control Act (TSCA), which is found in 40 Code of Federal Regulations (CFR) Part 261.

Terracon conducted a representative visual assessment of light fixtures and pole and pad-mounted electrical transformers to characterize PCB content. Typically, ballasts manufactured prior to 1979 are presumed to contain PCBs unless clearly marked as containing “No PCBs”.

July 28, 2015 Terracon Project No. 58157036

Responsive Resourceful Reliable 5

Ballasts that do not contain a “No PCBs” label are presumed to be PCB-containing. Terracon observed that the majority of the lighting in the building was light emitting diodes (LED) and incandescent. However, three fluorescent lighting units were observed in the basement, which likely contain ballasts.

Transformers sometimes contain mineral oil which may contain minor amounts of PCB and could be considered “PCB contaminated” (PCB content of 50-499 ppm). During the assessment of the site, exterior pad-mounted and pole-mounted transformers were not observed in proximity to the building.

5.2 Mercury

Metallic mercury is a silver-white liquid at room temperature. Elemental and inorganic mercury compounds are used in manufacturing scientific instruments, electric equipment, mercury vapor lamps, and high intensity discharge (HID) lights. Mercury is considered a hazardous material due to its ability to bioaccumulate within the environment. Recycling mercury-containing components reduces the load of mercury entering the environment. The fluorescent light tubes observed in the basement may contain mercury. In addition, three mercury-containing thermostats were observed on the first floor. Prior to demolition, these items should be removed intact, packaged to prevent breakage and transferred to an approved recycling facility that recovers mercury.

5.3 CFC

A CFC is an organic compound that consists of carbon, hydrogen, chlorine, and fluorine. Many CFCs have been widely used as refrigerants, propellants, and solvents. Chlorofluorocarbons are believed to cause depletion of the atmospheric ozone layer.

Interior and exterior building areas were observed to potentially contain equipment (air conditioners and refrigerators), which may contain CFCs. Three air conditioner compressors and one water fountain were observed on the first floor during the assessment. Prior to demolition, CFCs (refrigerants) should be removed by a qualified recycling firm that recovers CFCs.

5.4 Lead Based Paint

Lead is regulated by the EPA and OSHA. The EPA regulates lead use, removal, and disposal, and OSHA regulates lead exposure to workers. The EPA defines LBP as paint, varnish, stain, or other applied coating that contains lead equal to or greater than 1.0 milligram per square centimeter (mg/cm2), 5,000 milligrams per kilogram (mg/kg), or 0.5% by dry weight as determined by laboratory analysis. For the purpose of the OSHA lead standard, lead includes

July 28, 2015 Terracon Project No. 58157036

Responsive Resourceful Reliable 6 metallic lead, all inorganic lead compounds, and organic lead soaps. A synopsis of the OSHA regulations (29 CFR 1926.62) and the applicability are as follows:

The OSHA Interim Lead Standard for Construction (29 CFR 1926.62) applies to all construction work where an employee may be occupationally exposed to lead. All work related to construction, alteration, or repair (including painting and decorating) is included. The lead-in-construction standard applies to any detectable concentration of lead in paint, as even small concentrations of lead can result in unacceptable employee exposures depending upon on the method of removal and other workplace conditions. Under this standard, construction includes, but is not limited to, the following:

Demolition or salvage of structures where lead or materials containing lead are present

Removal or encapsulation of materials containing lead

New construction, alteration, repair, or renovation of structures, substrates, or portions containing lead, or materials containing lead

Installation of products containing lead

Lead contamination/emergency clean-up

Transportation, disposal, storage, or containment of lead or materials containing lead on the site or location at which construction activities are performed

Maintenance operations associated with construction activities described above

The U.S. Department of Housing and Urban Development (HUD) and EPA require that tenants be notified of the presence of LBP in residential buildings and be provided with a copy of the HUD and EPA pamphlet Protect Your Family From Lead In Your Home. Tenants must also be notified of any renovation activity likely to disturb LBP in their unit or in common areas.

Terracon observed the interior painted surfaces to be in good condition with no areas of peeling paint. Peeling paint was observed throughout the building exterior with some paint chips present on the ground surface. The paint was the existing color of the building. While evaluating the building materials, Terracon exposed a second layer of siding beneath the outer layer. The second layer was horizontal wooden lap siding painted white with no peeling observed. White paint chips were not observed. No paint chips were submitted for laboratory analysis of lead.

5.5 Batteries

Batteries containing nickel-cadmium and lead-acid can be found in emergency lighting, exit signs, and alarm systems. The nickel-cadmium and lead-acid in these batteries are considered to be toxic.

July 28, 2015 Terracon Project No. 58157036

Responsive Resourceful Reliable 7

Interior and exterior building areas were not observed to contain emergency lighting and/or alarm systems that could potentially contain batteries. Terracon observed exit signs that did not contain batteries.

5.6 Radioactive Sources

There are several types of smoke detectors and fire alarms which could have radioactive sources. Ionization chamber and photoelectric smoke detectors are the two most common types available commercially.

Ionization chamber smoke detectors contain a small amount of radioactive material encapsulated in a metal chamber. Typically, the radioactive material is a composite of americium-241. During the assessment of the site, radioactive sources were not observed.

5.7 Mold

In conjunction with the site reconnaissance, Terracon observed the exterior and the accessible interior areas of the on-site building for visual evidence of water infiltration and suspect mold growth. The observations included visibly accessible surfaces in the building areas visited, and did not include observations of hidden conditions such as inaccessible areas, interior of wall cavities, interior of heating, ventilation and air conditioning (HVAC) systems, or behind intact wall coverings.

The source of excess moisture is typically related to leaky plumbing or roofing, but can also involve the building’s HVAC system. When excess moisture accumulates in buildings, mold growth will often occur. In the presence of sufficient moisture, different molds can grow on wood, paper, carpet, or insulating materials. Molds reproduce through spores that cannot be seen with the naked eye. When they settle on damp indoor surfaces, active mold growth can begin. Moisture control is the key to controlling mold growth in indoor environments.

Terracon did not observe obvious indications of significant water infiltration or visible mold growth at the time of the site reconnaissance. However, site personnel indicated mold remediation had been performed in the building in the past. In addition, a mold-like or mildew-like odor was present to varying degrees inside the building; the odor was most noticeable in the basement. The dehumidifier in the basement was not operational during the initial site walk, but personnel restarted the dehumidifier at that time. The walls of the basement showed some signs of effervescence, indicating possible moisture seepage.

Responsive Resourceful Reliable 8

5.8 Biohazards

Terracon observed several mouse traps in the basement and on the second floor of the building. Skeletal remains of a mouse were observed in one of the traps on the second floor.

Mouse droppings were also observed.

5.9 Lead Soil Sampling

In addition, per your July 9, 2015 voicemail request, Terracon developed and implemented a limited plan for sampling lead in soil samples collected from around the building on July 11, 2015.

Terracon collected six shallow soil samples from around the building. Each soil sample was collected from the upper six inches and within two feet of the building wall. Sample 1 was collected on the north side of the building. Samples 2 and 3 were collected on the east side of the building. Sample 4 was collect near the southwest corner of the building. Sample 5 was collected just south of the main entrance on the west side of the building. Sample 6 was collected beneath the exterior stairway leading to the second floor on the west side of the building.

The samples were submitted under proper chain of custody procedures to a Wisconsin-certified laboratory for analysis of lead by US EPA Method 6010. The laboratory results identified lead concentrations ranging from 16.2 mg/kg to 208 mg/kg. The background threshold value (BTV) for lead in Wisconsin soils is 52 mg/kg. The presence of lead at concentrations above its BTV may be indicative of a release. Laboratory report and chain of custody are included in Appendix D.

Reporting the detections is required per Section 292.11, Wis. Stats, which is also known as the “Spills Law”. The statute requires that a person who possesses or controls a hazardous substance, which is discharged or who causes the discharge of a hazardous substance, shall notify the department immediately of any discharge not exempted by law.

However, Terracon is also aware that a petroleum underground storage tank (UST) system was formerly present at this site. A leak was identified and a leaking UST (LUST) case was opened by the Wisconsin Department of Natural Resources (WDNR) on April 25, 1990. The LUST case was assigned the Bureau of Remediation and Redevelopment Tracking System (BRRTS) #03- 04-000175 (http://dnr.wi.gov/botw/GetActivityDetail.do?adn=0304000175&siteId=3257100&crumb=1&search=b).

Elevated concentrations of lead were detected in several soil samples collected during the LUST case investigation. It is not obvious whether the concentrations of lead detected in the soil samples are elevated due to LBP falling from the building or from spilled leaded gasoline.

Administrative Code (WAC). If desired, soil and/or groundwater sampling can be performed in conjunction with drilling performed for geotechnical purposes as a cost-saving measure.

6.0 LIMITATIONS/GENERAL COMMENTS

Terracon did not perform sampling which required demolition or destructive activities such as knocking holes in walls, dismantling of equipment or removal of protective coverings, beyond what was deemed acceptable to NPS personnel. Reasonable efforts to access suspect materials within known areas of restricted access (e.g., crawl spaces) were made; however, confined spaces or areas which may pose a health or safety risk to Terracon personnel were not sampled. Sampling did not include suspect materials which could not be safely reached with available ladders/man-lifts.

This asbestos survey was conducted in a manner consistent with the level of care and skill ordinarily exercised by members of the profession currently practicing under similar conditions in the same locale. The results, findings, conclusions and recommendations expressed in this report are based on conditions observed during our survey of the building. The information contained in this report is relevant to the date on which this survey was performed, and should not be relied upon to represent conditions at a later date. This report has been prepared on behalf of and exclusively for use by SFS Architecture for specific application to their project as discussed. This report is not a bidding document. Contractors or consultants reviewing this report must draw their own conclusions regarding further investigation or remediation deemed necessary. Terracon does not warrant the work of regulatory agencies, laboratories or other third parties supplying information which may have been used in the preparation of this report.

No warranty, express or implied is made.

*Estimated quantities are based on a cursory field evaluation, and actual quantities may vary significantly, especially if asbestos containing materials are present in hidden and/or inaccessible areas not evaluated as part of this survey.

**% & Type Asbestos = this column contains both the analytical result of the sample with the highest concentration of asbestos detected in the samples that make up the HA and the types of asbestos identified.

The materials listed in this table have been sampled and determined to contain asbestos in concentrations greater than 1%. When disturbed, various federal, state and local regulations may apply. These materials should be monitored for damage over time and repaired as necessary by appropriately trained personnel. Removal may be necessary before renovations and in most cases before a demolition. See Appendix B for a summary of samples collected. See Appendix C for detailed analytical results.

*Estimated quantities are based on a cursory field evaluation, and actual quantities may vary significantly, especially if asbestos containing materials are present in hidden and/or inaccessible areas not evaluated as part of this survey.

Assumed materials are materials that are commonly determined to contain asbestos that could not be sampled during the survey. Reasons for not sampling can include lack of accessibility (high ceilings), structural integrity (roofing) or other sampling limitations. Assumed asbestos containing materials should be monitored for damage and treated as asbestos containing material. These materials should be sampled before any renovation or demolition activities that may disturb them to determine their actual asbestos content.
