1.1 INTRODUCTION

In accordance with written direction on July 24, 2023, Mr. John Varrati instructed O² Consulting, Inc/IBC, of Wesley Chapel, Florida, to perform a demolition asbestos survey for the buildings located at 12701 N. Florida Avenue, Tampa, Florida. The survey was conducted pursuant to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) requirements. The following Survey Report details the findings of the Demolition Asbestos Survey for the referenced facility.

A preliminary site inspection was performed on July 28, 2023, with the survey being performed on the same day. Mr. Oris Voigtmann conducted the survey.

1.2 SITE DESCRIPTION

The subject property is comprised of a four single story buildings and two wood sheds located at 12701 N. Florida Avenue, Tampa, Florida. The buildings are currently unoccupied. The buildings were constructed of wood framing on wood trusses or concrete block on a concrete foundation. The interior partitions were a plaster/drywall system on stud construction. The flooring was carpet, vinyl flooring or ceramic tile on concrete.

1.3 PURPOSE

The purpose of conducting the survey for the subject complex is to:

● Locate and identify all types of Asbestos Containing Materials, ACM throughout the accessible areas.

● Assess the existing physical condition of the ACM and determine the relative hazards presented.

● Recommend response actions in accordance with the assigned "Hazard Priority Rating" for each type of ACM identified.

● Prioritize the ACM and physical areas in order of the specific response action required.

1.4 SCOPE

The Scope of Work for this survey is as follows:

● Review available construction documents to determine potential locations of ACM and to develop sample plans.

● Conduct a field investigation to access and perform a visual inspection of

3 16 all accessible areas of the units to be surveyed.

● Collect bulk samples of suspect ACM identified.

● Provide bulk sample analyses by an independent and accredited laboratory.

● Assess condition of identified ACM and assign a “Hazard Priority

Rating”.

● Prioritize those materials and areas which require response actions.

● Recommend appropriate response actions.

1.5 SAMPLING LOGIC AND PROTOCOL

The survey protocol involved the following sequences, where available or appropriate:

1. Interview persons to elicit information regarding building construction, use of facilities (past, present and future), number of building occupants, maintenance and custodial procedures, dates of construction, HVAC design, water systems, size of units/buildings, and other information as appropriate.

2. Review of previous inspection/survey reports, laboratory data, results, building plans, construction specifications, and other pertinent documents, if available.

3. A brief walk-through of the facility to be surveyed allowed conclusions to be made concerning the number of samples needed, access problems that were to be encountered, photographic needs, and degree of protection necessary for bulk sample collection.

4. A visual inspection was conducted to identify the locations of all suspect ACBM and physically touch the material to determine if it was to be classified as friable (easily crumbled) or non-friable. Suspect materials were then catalogued according to their intended use. These categories include surfacing materials, thermal system insulation, and miscellaneous materials. Surfacing materials include sprayed or troweled-on fireproofing, acoustical, and decorative insulation, as well as insulations used for condensate control. Thermal system insulation, or TSI, includes pipe lagging, boiler and hot water storage tank insulation, and insulation on duct, pumps, heat exchangers, or other equipment. Miscellaneous suspect materials include interior building materials on structural components, structure members, or fixtures, such as floor and ceiling tiles, asbestos-cement board, and flue pipes, that did not fall into one of the previously mentioned categories.

5. Bulk sampling was conducted using United States Environmental Protection Agency (USEPA) Asbestos Hazard Emergency Response Act (AHERA) as a guideline and USEPA National Emission Standards for Hazardous Air Pollutants (NESHAP) protocols, however the inspector will determine the number of samples taken per their discretion and contract. These procedures required a random method, which was used to select sampling locations from each homogeneous sampling area. A homogeneous area is defined as an area of surfacing material, thermal system insulation material, or miscellaneous material that is uniform.

6. Bulk samples were transported to the analytical laboratory where they were logged in and assigned a unique laboratory identification number.

All samples were analyzed for asbestos content by polarized light microscopy (PLM) using the "Interim Method for the Determination of Asbestos in Bulk Insulation Samples" found at Appendix A to Subpart F in EPA 600/M-4-020. In this method the presence of asbestos in a sample was determined by optical mineralogy using a light microscope with two polarizing filters. Asbestos identification was achieved by examining the morphology and optical properties of the sample. The optical properties include the color under dispersion staining, birefringence, extinction characteristic, and the sign of elongation.

Quantification was obtained by visual estimation. This method may be used for the analysis of samples containing from 0 to 100 percent asbestos. The lower limit of detection is less than 1 percent. The upper detection limit is 100 percent.

Results are reported as percent asbestos by type (e.g. chrysotile, crocidolite).

Additional information such as other fibrous components in the sample and the non-fibrous sample matrix may also be supplied, if available.

7. This survey report does not intend to acknowledge, imply, or warrant the inspection for Asbestos Containing Building Materials in areas not normally considered readily accessible through standard survey protocol. These areas include, but are not limited to:

● Inaccessible spaces below floor levels

● Materials below ground surfaces

● Materials in areas considered inaccessible or unsafe

1.6 BULK SAMPLE ANALYSIS

All bulk sample analysis was performed by National Voluntary Laboratory Accreditation Program (NVLAP) accredited Eurofins CEI Inc., 730 SE Maynard Road, Cary, NC 27511, via Polarized Light Microscopy (PLM) coupled with dispersion staining in general accordance with EPA 600/M-4-020. A copy of the laboratory results can be found in Appendix A. Summary results were as follows:

NAD- no asbestos detected

1.7 HAZARD ASSESSMENT

Sample results indicated that none of the materials tested contained asbestos minerals.

1.8 SYNOPSIS & RECOMMENDATIONS

A preliminary site inspection determined the following building components to be suspect asbestos-containing materials:

• Plaster/drywall system • Flooring •Adhesives • Roofing

In conclusion, it is clearly understood that O² Consulting, Inc/IBC does not intend this report to be representative of all potential Asbestos Containing Material (ACM) in this facility and is strictly limited to the materials tested and the limitations of the laboratory testing technology methods.
