(AIHS) is pleased to submit the following report for a pre-renovation survey for Asbestos-Containing Building Materials (ACBM) and Lead-Based Paint (LBP) conducted September 21, 2016 at the above-referenced facility. The asbestos survey portion of this report was performed to meet the current NESHAP regulation and the DEP South District prior to conducting planned renovation activities in the facility. Facility Description & Project Scope The subject facility consists of a large retail store in the Granada Shoppes Shopping Center located in Collier County, Florida. It has two sections designated north and south and has a combined measured area of approximately 36,000 ft 2. According to the Broward County Property Appraiser, was constructed in Structural components include a concrete foundation on-grade, masonry block (CMU) and pre-cast concrete tilt-up walls, and a flat sheet metal roof deck (supported by steel joists and steel columns). According to the customer, the planned renovation entails extensive modifications to the interior spaces. The scope of this project was to sample and identify any ACBM and/or LBP that may be present in the facility that may require special treatment prior to or during the planned renovation. Note: No samples were collected from the facility roof or from any components that may be located on the facility roof NW 97 th Avenue Cooper City, Florida Tel (305) (954)

2 Pre-Renovation Survey for ACBM & LBP: Commercial Space 1000 Immokalee Road, # 30 Naples, Florida October 3, 2016 AIHS Project # Sampling Strategy - ACBM The National Emission Standard for Asbestos (Subpart M 40 CFR Part to 157 and Appendix A) of the National Emission Standard for Hazardous Air Pollutants (NESHAP) deals with Regulated Asbestos Containing Materials (RACM) during renovation and demolition activities. According to the NESHAP, only friable RACM and RACM that may become friable need be addressed in buildings that are scheduled for complete demolition. To meet the requirements of some counties, category I non-friable ACM including resilient vinyl flooring materials and roofing materials were also addressed as part of this project. All accessible areas of the facility were inspected. Bulk sample specimens of materials suspected of containing asbestos were collected and submitted for analysis by Polarized Light Microscopy in conjunction with dispersion staining as outlined in 40 CFR, Part 63, Subpart F dated January Analysis will be conducted by Advanced Industrial Hygiene Services, Inc. is accredited for asbestos fiber analysis through successful participation in the National Voluntary Laboratory Accreditation Program (NVLAP) and meets the requirements of section 206(d) of Title II of the USC Chapter 15, TSCA as stated in 40 CFR 763 dated April 30, Samples of materials suspected of containing asbestos were collected based on the following plan: Friable Surfacing Materials: Friable surfacing materials, where encountered, are sampled based on the recommendations found in the EPA Pink Book entitled Asbestos in Buildings: Simplified Scheme for Friable Surfacing Materials (EPA document 560/ a). The number of samples collected is based on the total square footage of the homogenous area of the material. If less than 100 ft 2 of suspect friable surfacing material is present, two samples are collected. If the area is between 100 and 1000 ft 2, three samples are collected. If the area is between 1000 and 5000 ft 2, five samples are collected. If the area is between 5000 ft 2 and 10,000 ft 2, seven to nine samples are collected. One additional sample was collected for each additional 5,000 ft 2 of homogenous material. Thermal System Insulation (TSI): At least three (3) samples of suspect TSI are collected in a randomly distributed manner from each homogeneous area of TSI not assumed to be ACM. At least one (1) bulk sample is collected from each homogeneous area of patched TSI. Where cement or plaster is used on fittings such as tees, elbows, or valves, samples were collected in such a manner sufficient to evaluate whether the material is ACM or not ACM. 2

3 Pre-Renovation Survey for ACBM & LBP: Commercial Space 1000 Immokalee Road, # 30 Naples, Florida October 3, 2016 AIHS Project # Miscellaneous Materials: This includes materials such as acoustical ceiling tiles, wallboard, joint compounds, resilient vinyl flooring, mastics, etc. (basically, anything that does not fall into the first two categories). Suspect miscellaneous materials were sampled in such a manner as to evaluate whether or not they contained asbestos. The number of samples collected of a given miscellaneous material was left to the discretion of the inspector. As a general rule, AIHS collects three samples of each distinct type of suspect miscellaneous material present. Bulk sample specimens of materials suspected of containing asbestos were collected and submitted for analysis by Polarized Light Microscopy in conjunction with dispersion staining as outlined in 40 CFR, Part 63, Subpart F dated January Analysis was conducted by Advanced Industrial Hygiene Services, Inc. who is accredited for asbestos fiber analysis through successful participation in the National Voluntary Laboratory Accreditation Program (NVLAP) and meets the requirements of section 206(d) of Title II of the USC Chapter 15, TSCA as stated in 40 CFR 763 dated April 30, The laboratory analytical report and sample chain-of-custody for the bulk samples collected as part of this project are located in Appendix A of this report. Sampling Strategy - LBP Testing for lead-based paint was conducted by (certification # FL-R ) based on the U.S. Department of Housing and Urban Development Guidelines for the Evaluation and Control of Lead-Based Paint in Housing, Chapter 7, Lead-Based Paint Inspection, 1997 Revision. However, this inspection is limited such that it does not meet the specific requirements of the HUD Guidelines. AIHS used a Thermo Fisher Scientific Niton Model XLp 303A Lead Paint Analyzer (serial # 24602) to measure concentrations of lead in paint by area in milligrams per square centimeter (mg/cm 2 ) for direct comparison with the HUD and EPA criteria for classification of paint as lead-based. The instrument s Performance Characteristics Sheet (PCS) documents no inconclusive readings and allows no need for substrate correction. Therefore, no paint chip samples were collected as part of this project. XRF readings were taken from painted surfaces from readily accessible testing combinations observed on the exterior and interior of the subject structures (Location, component description and paint color were recorded for each reading. Reading locations were designated according to compass points. 3

4 Pre-Renovation Survey for ACBM & LBP: Commercial Space 1000 Immokalee Road, # 30 Naples, Florida October 3, 2016 AIHS Project # A total of forty-six (46) XRF readings were taken as part of this project as follows: Instrument Shutter Calibrations (2) Lead Paint Standard Calibrations (2) Readings from painted surfaces: Exterior Surfaces (15 reading) Interior Surfaces (27 readings) Paint standard calibration readings were taken at the beginning and end of the site visit. XRF readings were taken from the following representative painted surfaces: Walls (interior & exterior) Ceiling Columns (interior & exterior) Trim Floors Doors Doorframe Baseboards Posts The acquired data and XRF test results obtained in the performance of this project are included in Appendix B of this report. 4

5 Pre-Renovation Survey for ACBM & LBP: Commercial Space 1000 Immokalee Road, # 30 Naples, Florida October 3, 2016 AIHS Project # Findings - ACBM Those suspect asbestos-containing materials that were present in the subject facility are listed below: Flooring Materials: Floor substrate consists of the poured concrete floor decks. Predominant floor finish materials consist of adhered resilient vinyl flooring including strips and squares. Additional floor finishes included ceramic tiles set in grout and wall-to-wall carpet. Representative samples were collected of the concrete foundation, each type of resilient vinyl floor finish (with associated mastic adhesive), ceramic tiles with grout, and carpet with mastic. All samples of floorassociated materials were reported by the laboratory to contain no detectable quantities of asbestos. Wall Materials: Structural walls consist of pre-cast concrete and concrete masonry unit (CMU) system. Exterior and some interior walls have a painted stucco finish. Most interior walls consist of drywall paneling finished with drywall joint compound and paint. Numerous display walls have grouted ceramic tiles and adhered wood slats. Representative samples were collected of exterior stucco, drywall system materials, and ceramic tile system materials. All samples of wall materials were reported by the laboratory to contain no detectable quantities of asbestos. Ceiling Materials: Ceiling materials consist of the exposed sheet metal undersurface of the roof deck in the majority of the south half. The north half has 2 X 4 ft 2 acoustic ceiling tiles in a suspended metal grid and a small area of 2 X 2 ft 2 acoustic ceiling tiles (in a suspended metal grid) are present in a room near the entrance to the south half. Representative samples were collected of both types of ceiling tiles and all were reported by the laboratory to contain no detectable quantities of asbestos. Heating, Ventilation and Air-Conditioning (HVAC) System: The facility has multiple package roof top units (RTUs). Ducts on most of the units drop vertically through the ceiling to integrated supply and return vents in the suspended ceiling system. A few of the RTUs have duct systems (composed of formed-in-place duct-board and flex ducts that are sealed with foil tape). No suspect asbestos containing materials were observed associated with HVAC system components in the facility. Thermal System Insulation (TSI) Materials: No TSI system materials were observed in the facility. 5

6 Pre-Renovation Survey for ACBM & LBP: Commercial Space 1000 Immokalee Road, # 30 Naples, Florida October 3, 2016 AIHS Project # Additional Miscellaneous Materials: Additional suspect miscellaneous materials identified in the facility consisted of mastic dabs behind the wooden slats on some of the interior walls and caulk inside some of the joints in the concrete foundation. Representative samples were collected of each of these materials and all were reported by the laboratory to contain no detectable quantities of asbestos. Assessments of ACM No asbestos-containing materials were identified which may become disturbed or damaged as a result of the planned renovation activity. Findings - LBP The following tested painted surfaces yielded lead concentrations by area in excess of 1.0 mg/cm 2 thus meeting the EPA classification as lead-based paint: Yellow paint on the floor near the south walls by the Back-of-House (BOH (4.3 mg/cm 2 ) A photograph of the identified lead-based paint appears below: Note paint on wall was not lead-based paint All other tested painted surfaces yielded lead concentrations below 1.0 mg/m 2 thus indicating that the paint did not meet the USEPA classification as lead-based paint. 6

8 Pre-Renovation Survey for ACBM & LBP: Commercial Space 1000 Immokalee Road, # 30 Naples, Florida October 3, 2016 AIHS Project # The disturbance of LBP coatings is regulated by the Occupational Safety and Health Administration (OSHA), which have noted that the HUD LBP definition may not be applicable to its regulations. The OSHA regulation (29 CFR ) does not define lead content of the coating, but instead, regulates the disturbance of the materials with any lead content. The permissible exposure limit (PEL) propounded by OSHA for occupational exposure to lead (based on an 8-hour time-weighted average is 50 micrograms per cubic meter (µg/m 3 ) and the action level (AL), the level at which the employer must take certain actions, is 30 µg /m 3. Those components/colors not tested, or in locations not inventoried in this report, should be tested for lead content prior to any disturbance (repair, renovation, abatement, or demolition) that may cause airborne release of lead. Components/colors that may be identified to contain the presence of lead should not be disturbed in any uncontrolled manner, such as during repair, renovation or demolition. Any disturbance of these materials should be done by properly trained personnel in a controlled and documented manner. The disposal of waste materials containing lead from renovation, abatement and/or demolition is regulated by RCRA. RCRA requires a waste toxicity characteristic on the waste by using TCLP (40 CFR ). The TCLP extract is analyzed for lead (or other constituents) to determine if it is above or below the allowable TC regulatory threshold, which for lead is 5 ppm, or mg/l. Disclaimer AIHS evaluation was performed with limitations inherent to visual inspections. AIHS has conducted this assessment with reasonable care and has performed this study within general industry standards. As with any study of this nature, limitations are inherent. This inspection report is the result of a diligent search of the facility for asbestos-containing building materials and lead-based paint. The purpose of this inspection was to identify asbestoscontaining materials and lead-based paint that may require special treatment prior to proceeding with a planned renovation operation. However comprehensive this inspection appears, it does not claim to have identified all of the asbestos-containing materials and lead-based paint that may be present in the facility. Materials located sub-surface or below grade and/or in otherwise inaccessible locations were not addressed and are excluded from this pre-renovation survey for ACBM & LBP. 8
