Asbestos Survey of 9 Residential Structures on Carver Drive Panama City, Florida Dear Mr. Cronwell: As requested, Southern Earth Sciences, Inc., has completed an asbestos survey of 9 residential structures located on Carver Drive in Panama City, Florida. The units were located at 1447, 1448, 1449, 1451, 1453, 1455, 1456, 1457 and 1459 Carver Drive. We understand that the buildings are scheduled for demolition. This report will provide the results of our investigation. 1.0 INTRODUCTION On October 30, 2017, asbestos surveyors with our firm obtained a total of eighty-eight (88) bulk samples of suspect asbestos-containing building materials for analysis. Ninety-four (94) samples were analyzed due to multiple layered samples. The samples consisted of drywall, drywall joint compound, window caulking, vinyl floor tile, floor tile mastic, vinyl floor sheeting and shingles. The bulk samples were sent to Carolina Environmental, Inc, an analytical laboratory in Cary, NC. Bulk samples were analyzed by Polarized Light Microscopy (PLM), E.P.A. Method 600/R-93/116. Asbestos analytical results are attached. 2.0 DEFINITIONS Asbestos Containing Materials (ACM): Building materials used for construction of a structure that are known or are suspect for containing asbestos. Asbestos: Asbestos is the asbestiform varieties of chrysotile, crocidolite, amosite, anthophylite, tremolite, and actinolite. Asbestos Inspection: An evaluation performed by a trained and E.P.A. certified inspector to determine the presence or absence of Asbestos-containing materials. Asbestos inspectors engage in the survey and assessment of ACBM. Category I non-friable ACM: asbestos-containing packings, gaskets, resilient floor covering and asphalt roofing products.

2 Carver Drive Page 2 Category II non-friable ACM: any material, excluding Category I ACM, that when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure. Demolition: the removal of load-bearing walls or structural components. OSHA Occupational Safety & Health Administration. Regulated Asbestos Containing Material (RACM): (a) Friable asbestos materials, (b) Category I non-friable ACM that has become friable, (c) Category I non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading, or, (d) Category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations regulated by NESHAPS. Renovation: the removal of any other building components other than load-bearing walls or structural components. 3.0 PHYSICAL SURVEY According to the information from the Bay County Property Appraiser s Office, the residential structures located at the aforementioned addresses were listed as constructed in All buildings were single story wood frame buildings on pier foundations. Piping in the crawlspaces was bare metal. Roofing was metal on wood framing. Windows had caulking around the perimeter of openings. Units were heated using floor mounted heaters. No air conditioning was observed in any unit Interior walls were wood paneling and drywall. The ceiling was drywall. The floors were wood with vinyl floor tile in the entry way/living room and in the bathroom The water heater was located under a small covered area with shingles and mastic around the vent pipe. Interior walls were drywall, most of which was damaged. The ceiling was drywall. The floors were wood with vinyl floor sheeting in the kitchen, bathroom and living room. There were 4 layers of vinyl floor sheeting in the living room, 2 layers in the kitchen and one layer in the bathroom The water heater was located under a small covered area with shingles and mastic around the vent pipe. The ceilings and walls were drywall. The floors were wood There were no shingles or mastic on the water heater cover. The ceiling was drywall. The walls were wood paneling or drywall. The floors were wood. Plywood was located over vinyl floor tile in the bathroom.

3 Carver Drive Page There was mastic located around the vent pipe of the water heater cover. Ceilings were drywall. The walls were drywall and wood paneling over drywall. The floors were wood Shingles were located on the hot water heater cover. The ceilings were drywall. The walls were drywall and wood paneling over drywall. The floors were wood Shingles were located on the hot water heater cover. The ceilings were drywall. The walls were drywall or wood paneling over drywall. The floors were wood in the kitchen and one bedroom. The living room and bedroom with the attached bathroom had 12 x12 vinyl floor tile over wood floors There was no mastic or shingles on the hot water heater cover. The ceilings were drywall. The walls were wood paneling over drywall. The floors were carpeting over wood with vinyl floor sheeting under the carpeting in the kitchen and living room Mastic was present around the hot water vent pipe. The ceilings were drywall. The walls were drywall or wood paneling over drywall. The floors were wood. 4.0 SUMMARY OF FINDINGS The E.P.A. definition for an asbestos-containing material is a building material that contains more than 1 percent asbestos when analyzed by PLM, and is placed into two categories; friable and nonfriable. Friable ACM is a material that can be easily pulverized with hand pressure as opposed to non-friable ACM. 4.1 FRIABLE ACM There were no friable asbestos containing materials identified in any of the buildings surveyed. 4.2 NON-FRIABLE ACM Units 1447, 1451, 1453, 1455, and 1459 There were no asbestos containing materials identified in these buildings. Unit The drywall joint compound contained 2% Chrysotile asbestos. The composite sample contained <1% Chrysotile asbestos. The joint compound was not used as a surfacing material. We should note that there is only a very small amount of drywall compound used on the drywall. Most of the drywall panels were nailed onto framing and the seams were covered with wood strips. Gaps were small and contained a small amount of compound if any. Unit The drywall joint compound contained <1% Chrysotile asbestos. The joint compound was not used as a surfacing material. We should note that there is only a very small amount of drywall compound used on the drywall. Most of the drywall panels were nailed onto

4 Carver Drive Page 4 framing and the seams were covered with wood strips. Gaps were small and contained a small amount of compound if any. The bottom layer of vinyl floor sheeting located in the living room and entryway contained 2 Chrysotile asbestos. There was approximately 144 square feet of vinyl floor sheeting (bottom layer) located in the unit The drywall joint compound contained 2% Chrysotile asbestos. The composite sample did not contain asbestos. The joint compound was not used as a surfacing material. We should note that there is only a very small amount of drywall compound used on the drywall. Most of the drywall panels were nailed onto framing and the seams were covered with wood strips. Gaps were small and contained a small amount of compound if any The drywall joint compound contained <1% Chrysotile asbestos. The joint compound was not used as a surfacing material. We should note that there is only a very small amount of drywall compound used on the drywall. Most of the drywall panels were nailed onto framing and the seams were covered with wood strips. Gaps were small and contained a small amount of compound if any. 5.0 CONCLUSIONS AND RECOMMENDATIONS In accordance with the National Emission Standards for Hazardous Air Pollutants (NESHAPS), 40 CFR Part 61, Subpart M, Regulated Asbestos Containing Materials (RACM) are required to be removed prior to building demolition. The vinyl floor sheeting is classified as a Category I non-friable ACM. The drywall joint compound is classified as a Category II non-friable ACM. Both of these materials may become friable during demolition. Therefore these materials must be removed prior to demolition. joint compound requiring removal is present in units 1448 and Vinyl floor sheeting requiring removal is present in unit Some of the drywall joint compound sampled did not contain asbestos. Not all walls or ceilings were sampled and there may be a possibility that asbestos may be located in drywall joint compound not sampled or accessed. We would recommend that ALL buildings be demolished using wet methods under the direction of an asbestos competent person to ensure that the buildings are adequately wetted during demolition and reduce the chances of accidental exposure to demolition workers. Removal of asbestos containing materials must be performed by an Asbestos Abatement Contractor licensed by the State of Florida, with certified personnel. ACM abatement must comply with the State of Florida Department of Business and Professional Regulation, Chapter 469, licensing and training; Chapter , Waste Disposal Rules; Chapter , DEP 1999, Asbestos Program and OSHA 29 CFR (Construction Industry Standard).

5 Carver Drive Page 5 NESHAPS requires a 10-working day notification to the Florida Department of Environmental Protection (FDEP) Division of Air Management prior to the start date of an asbestos abatement project and 10 working day notification prior to renovation activities that will disturb asbestos containing materials or prior to demolition. 6.0 GENERAL COMMENTS This asbestos survey has been performed to identify asbestos containing materials in the existing buildings and is not intended as abatement specifications and drawings. Comments and observations given above reflect an opinion as to the various materials and conditions visually observed during the inspections and should not be construed as a representation or warranty expressed or implied, as to scope, thoroughness or accuracy of the inspection. A conscious effort is made to identify all suspect materials. There is a possibility that conditions or materials may exist which could not be identified during our survey due to physical inaccessibility and the use of nondestructive sampling methods. Materials that typically do not contain asbestos have not been sampled. These materials include but are not limited to rubber, fiberglass, etc. Conclusions and recommendations given in this report are based upon our interpretation of current regulatory standards. Changes in regulatory standards may require changes in our conclusions and recommendations. We appreciate the opportunity to be of service to you on this project.
