1.1 PURPOSE

The purpose of this survey was to identify asbestos-containing materials (ACM) within the interior, exterior and roof of the building; to determine if Other Regulated Materials (ORM) materials were present; to complete a waste stream analysis for Toxicity Characteristic Leachate Procedure (TCLP) Resource Conservation and Recovery Act (RCRA)-8 metals and Polychlorinated Biphenyls (PCBs); and to collect soil samples for organochlorine pesticides (OCP) for each structure. Diagrams depicting sampling locations are provided in Appendix II.

The investigation was conducted to facilitate the repairs at Tyndall Air Force Base following Hurricane Michael.

1.2 SITE DESCRIPTION

Building 526 Lox Cart Maintenance was a 960 square foot, single-story structure built in 2002.

The building was constructed of concrete block on a concrete slab foundation. The roof was constructed with a standing seam metal roof deck. The ceilings were constructed of drywall system. The interior walls were constructed of concrete block and drywall system. The floor was bare to the concrete slab.

1.3 DEMOLITION OVERVIEW

A diagram illustrating the general layout of the site was prepared using files provided by the client if available or drawn onsite by the AirQuest inspector. AirQuest prepared aerial photographs and photographed an overview of the interior and exterior of the building for purposes of assisting

AirQuest Project #15671 2 Building 526 Pre-Demolition W912DY-19-P-0053 Asbestos, Hazardous Materials & Soil Testing contractors in evaluation of the demolition requirements. The diagram and photographs are included in Appendix III.

2 ASBESTOS SURVEY

A pre-demolition asbestos survey suitable to meet the requirements of the National Emissions Standard for Hazardous Air Pollutants (NESHAPs) and State of Florida regulations was performed at the site.

2.1 SURVEY METHODS

The sampling protocol used generally followed Asbestos Hazard Emergency Response Act (AHERA) guidelines. AHERA was promulgated by the United States Environmental Protection Agency (EPA) in 1987 and regulated public schools.

Suspect materials were differentiated into three categories: surfacing material, thermal system insulation, or miscellaneous material. Surfacing material is anything that is sprayed or troweled onto a surface; thermal system insulation is material used to insulate HVAC pipes, tanks, etc., and miscellaneous material is any other type of material.

A homogeneous area is defined as an area of surfacing material, thermal system insulation material, or miscellaneous material that is uniform in color and texture. A homogeneous area is not limited to only a room but can be found in several rooms. Sample selection in the building was determined by identifying the homogeneous areas and basing sampling locations upon these areas.

In conducting the building inspection in compliance with local, state, and federal regulations, all suspected ACM which were accessible to the inspector, were either sampled to confirm the actual presence of asbestos or assumed to contain asbestos.

2.2 LABORATORY ANALYSIS

Analysis was performed using Polarized Light Microscopy (PLM) with dispersion staining. The laboratory is rated proficient through National Institute of Standards and Technology- National Voluntary Laboratory Accreditation Program (NIST-NVLAP) for bulk asbestos analysis.

NESHAP defines ACM as containing more than 1% asbestos as determined using PLM (as specified in Appendix E, Subpart E, 40 CFR part 763, Section 1, Polarized Light Microscopy).

NESHAP defines friable ACM as any material containing more than 1% asbestos that, when dry, can be crumbled, pulverized or reduced to a powder by hand pressure. If the asbestos content of a friable material is less than ten (10) percent as determined by a method other than point counting by PLM, the client may elect to verify the asbestos content by point counting using PLM.

Because of the inherent limitations of PLM bulk sample analysis, any friable sample reported as <2% asbestos by PLM was automatically analyzed by the PLM point count method to determine whether it may be regulated under the asbestos NESHAP.

AirQuest Project #15671 3 Building 526 Pre-Demolition W912DY-19-P-0053 Asbestos, Hazardous Materials & Soil Testing

Estimates of quantities of ACM were based upon the identification of suspect materials. Where suspect ACM were located behind walls, above ceilings, beneath carpeting, or other concealed conditions and the quantities cannot be verified, the estimate is based upon the conditions present during the survey. These estimates are not to be considered absolute and should be verified when the ACM is exposed.

2.3 SUSPECT ASBESTOS-CONTAINING MATERIALS

Homogenous areas (HA) of suspect material were identified and samples were collected and submitted under chain of custody to EMSL Analytical, Inc. (“EMSL”) for laboratory analysis of asbestos by PLM. If identified, friable samples with <2% asbestos were further analyzed by the PLM point count method to confirm the PLM results. A copy of the laboratory report and chain of custody record is included in Appendix IV.

Sample descriptions and laboratory results are summarized in Table 2. Photographs of each HA are included in Appendix V.

3 LEAD BASED PAINT SCREENING

An inspection was conducted to screen for the existence of lead containing painted building components. Testing of the painted building components was performed using an XRF Spectrometer. The XRF is a screening instrument currently recommended by the US Department of Housing and Urban Development (HUD) for analysis of lead levels in paint. The screening was used to assist in determining the need and relative concentrations of lead on painted building

AirQuest Project #15671 5 Building 526 Pre-Demolition W912DY-19-P-0053 Asbestos, Hazardous Materials & Soil Testing components for purposes of designing a sampling scheme for a composite waste stream analysis and demolition contractor worker protection information. The screening was not intended to be a lead-based paint survey in accordance with HUD guidelines. A summary of the screening results is included in Table 3.

4 TCLP RCRA METALS

A waste stream composite sample was collected from the building for laboratory analysis of TCLP RCRA-8 Metals.

4.1 TCLP SAMPLE COLLECTION

The sample composition was determined by the composition of the materials comprising the building. Each major building component (such as wood, metal, concrete, glass, etc.) was estimated as a percentage of the weight of the building whole. Once the composition of the building was estimated, representative samples were collected of each material, in an approximate weight proportion as shown in Table 4.

6 OTHER REGULATED MATERIALS INVENTORY

AirQuest conducted another regulated/hazardous materials inventory in general accordance with the Recommended Management Practices for the Removal of Hazardous Materials from Buildings

AirQuest Project #15671 7 Building 526 Pre-Demolition W912DY-19-P-0053 Asbestos, Hazardous Materials & Soil Testing

Prior to Demolition prepared by the University of Florida and sponsored by the Florida Department of Environmental Protection, 1999. The inventory included lamps, thermostats, and light switches potentially containing mercury; exit signs, emergency lights, and smoke alarms that have batteries; lighting ballasts which contain polychlorinated biphenyls (PCBs); transformers;

freon, hazardous chemicals and petroleum products; and lead pipes and roof vent flashings.

Certain assumptions for the inspection of fluorescent light ballasts for PCBs were utilized for the building inspections to be completed in a timely and cost-effective manner. As required by regulation, lighting ballasts must not contain PCBs and the label on the ballast must state “No PCB”. AirQuest inventoried 100% of the fluorescent lighting fixtures and inspected a representative of each type of fixture (i.e. 2-foot, 4-foot, etc.) for the “No PCB” labeling.

Each exit sign and emergency lights were presumed to each contain a single lead-acid rechargeable battery. Quantities and types of any ORM found are summarized in Table 7.

7 SOIL TESTING FOR ORGANOCHLORINE PESTICIDES

AirQuest advanced four (4) soil borings and collected two (2) samples at each boring location at depths of zero to six inches (0 - 6 in.) and eighteen to twenty-four inches (18 – 24 in.) below land surface using a properly decontaminated hand bucket auger. The samples were generally collected near the four corners of the building as shown in Appendix II.

The soil sampling was conducted in accordance with Florida Department of Environmental Protection (FDEP) Standard Operating Procedures SOP-001-01 FS 3000 (Soil) and SOP-001-01 FQ1000 (Field Quality Control Requirements). One boring log was completed for the building documenting the observed lithology, visually estimated moisture content, noticeable odors, soil color, sample collection times, sampler’s name, sampling interval and boring completion method.

The soil boring log and soil boring location photographs are included in Appendix VIII.

Samples were placed in dedicated sample containers provided by the laboratory and labeled according to the referenced building/structure, collection time, sampler’s name and analysis. A chain of custody form was completed to document the chronology of ownership, control and transfer of the samples. All samples were placed in a cooler filled with ice for transfer to the laboratory.

The soil samples were shipped to Eurofins TestAmerica (“TestAmerica”) in Pensacola, Florida, a NELAC accredited environmental laboratory licensed in the State of Florida, for analysis by EPA Method: 8081B (Organochlorine Pesticides by GC). It is noted that the soil samples were originally collected on 24 November 2019 but, due to laboratory error, were prepared outside of the required holding times. The site was resampled on 28 January 2020. Analytical results are summarized in Table 8. A copy of the laboratory report and chain of custody record is included in Appendix IX.

The analytical results indicate there are traces of OCPs 4,4’-DDD, 4,4’-DDE, 4,4’-DDT, Dieldrin, Heptachlor, and Total Chlordane above the laboratory method detection limit and some above the practical quantitation limit, in the soil samples. The detected concentrations do not exceed the Commercial/Industrial or Residential Soil Cleanup Target Levels (SCTLs) provided in Chapter 62-777 FAC, the criteria used by the FDEP.

8 CONCLUSIONS AND RECOMMENDATIONS

A thorough pre-demolition inspection for asbestos and hazardous materials was conducted at the site and an inventory of the materials was created. The soils surrounding the site were sampled and analyzed for pesticides. Based upon the results of the inspections, recommendations for each contaminant are discussed separately below.

8.1 ASBESTOS CONCLUSIONS AND RECOMMENDED RESPONSE ACTION

The results of our observation and laboratory analysis did not identify ACM within the samples collected from the site.

8.2 LEAD SCREENING & OSHA LEAD GUIDANCE

Lead was identified in the paint at the site. Under the present OSHA lead construction standard, all identified lead-containing materials affected by construction activities falls under the requirements of 29 CFR 1926. There are no current government guidelines defining a lead-based paint or lead concentration that creates a hazardous atmosphere when disturbed. Based on current OSHA guidelines, for those employees who will be disturbing lead-containing paint (LCP), their employer must make an initial determination by monitoring employee exposure if any employee is exposed to lead at or above 30 micrograms per cubic meter for an eight-hour time weighted average (30 µg/m3 8-hour time weighted average). The employer must implement OSHA prescribed protective measures until they can demonstrate that the employee exposure is not in excess of the action level.

In general, relatively low levels of lead were detected in the various coated surfaces surveyed.

Depending on the degree and type of disturbance of these surfaces (i.e. sanding, cutting, or demolishing), employers may be required to implement varying degrees of OSHA prescribed protective measures. These protective measures must be maintained until it can be demonstrated that employee exposures do not exceed the action level. The employer should also implement and maintain a written compliance program detailing the protective measures they will utilize to control lead exposure during renovation activities.

8.3 TCLP RCRA METALS / LEAD

The results of the laboratory analysis indicate that the waste stream generated from the site is non-hazardous.

8.4 PCBS

The results of the sampling and analysis did not identify PCBs in composite waste stream paint and concrete samples.

8.5 OTHER REGULATED MATERIALS

In general, the items inventoried may be recycled and reclaimed. Special disposal considerations may be required for the nitrogen and liquid oxygen tanks.

AirQuest Project #15671 13 Building 526 Pre-Demolition W912DY-19-P-0053 Asbestos, Hazardous Materials, and Soils Testing

8.6 SOIL CONCLUSIONS

The soil analytical results did not identify EPA Method 8081B compounds above the state of Florida Commercial/Industrial or Residential SCTLs.

9 LIMITATIONS

If any suspect hazardous/asbestos containing building materials are encountered during demolition activities that were not sampled in this report, the materials should not be disturbed until they have been sampled and identified as non-hazardous and non-ACM through appropriate investigation and/or laboratory analysis. Many of the roofs at Tyndall Air Force Base were sealed with an EPDM roofing system covering all the original roofing materials. It is possible, if not likely, that additional suspect asbestos materials are present under the EPDM and were not identified during the asbestos survey.

This report was prepared in a manner consistent with that level of care and skill ordinarily exercised by members of the profession currently practicing under similar conditions. This report was prepared for the exclusive use of the client and assigned agents and is not intended for any other purposes. Our report is based on the information available to us at the time of our investigation and limited in scope to the stated purpose and/or the area(s) inspected. Other conditions elsewhere in the site may differ from those in the inspected/ surveyed locations and such conditions are unknown, may change over time, and/or have not been considered. This report does not claim to identify all potential hazards and/or contaminants that may be present, nor does it imply any medical opinion on the relationship of potential health effects with any reported hazards and/ or contaminants. Our opinions are based on our findings and professional expertise, with no guaranty or warranty implied herein. Should additional information become available, we reserve the right to determine the impact, if any, of the new information on our opinions, conclusions, and recommendations if necessary, as warranted by the discovery of the additional information. AirQuest accepts no responsibility for interpretation of this report by others. Its contents shall not be used or relied upon by other parties without prior written authorization by AirQuest.
