1 5751 Miami Lakes Drive Miami Lakes, Florida Tel (305) Environmental Services, LLC Fax (305) March 2, 2018 EE&G Proposal #: Mr. Jeffrey Barrow, LEA Monroe County School District (MCSD) 242 White Street Key West, FL Subject: Revised Asbestos Pre-Demolition Survey Marathon High School: Manor Building, Adjoining Water Buffer Tank/Piping, and Building 14 (Concession Stand/Restrooms/Press Box) 350 Sombrero Beach Road Marathon, Florida Dear Mr. Barrow: EE&G Environmental Services, LLC (EE&G) was retained by the Monroe Country School District (Client) to conduct an asbestos survey of the Marathon High School: Manor Building, Adjoining Water Buffer Tank/Piping, and Building 14 (Concession Stand/Restrooms/Press Box), herein referred to as the subject areas located at 350 Sombrero Beach Road, Marathon, Florida. Some initial sampling was conducted in 2015 on the Concession structure. The initial survey of the Manor Building was performed on December 21, 2017 by Rey Garcia and Randy Alonso of EE&G (both certified under the Asbestos Hazard Emergency Response Act, (AHERA). An additional site visit and confirmatory roof sampling was conducted on February 28, 2018 by Richard Grupenhoff. This report will summarize the three visits. The purpose of this asbestos survey was to identify the presence, extent, and condition of asbestos-containing materials (ACM) that may be impacted as a result of planned demolition of the various structures for compliance with the Environmental Protection Agency (EPA) National Emissions Standards for Hazardous Air Pollutants (NESHAP), Monroe County and applicable State and Federal Guidelines. SUMMARY Samples were collected in; 2015, 2017 and February Between these three assessments, a total of 109 samples were collected of the following materials: Black parapet wall and mansard felts (30lb under felt) Black/grey parapet wall and mansard felts (90lb top felt) Black built-up roof field membrane (w/gravel). Brown barrel tile concrete shingles. Gray plaster system. Gray exterior stucco w/paint. White popcorn ceiling texture. White drywall system (DWS). White 2x4 laminate ceiling tile (CT). Gray 2x2 dot groove CT. Gray 2x4 dot groove CT. White heating, ventilation, air conditioning (HVAC) mastic. Gold HVAC seam mastic. Miami Melbourne Orlando Tampa

2 Mr. Jeffrey Barrow March 2, 2018 Page 2 Pink sink undercoat. Beige vinyl cove base (VCB). Blue VCB. Beige linoleum. Beige 12 x 12 vinyl floor tile (VFT) with mastic. Orange 12 x 12 VFT with mastic. Black felt paper. White field membrane. Gray cinder block. Gray concrete. White sink undercoat. Asbestos was found in amounts greater than 1% in the following materials: Black parapet felt/mastic system (seams on top felts & nailheads on bottom felts), Black mansard felt/mastic system (seams on top felts and nailheads on bottom felts), Black built-up roof field membrane (north central patch only), Pink sink undercoating METHODS And therefore are considered to be ACM. See attached laboratory results. The specified interior, exterior, and roofing building materials were inspected for suspect ACM, unless otherwise noted. Each observed suspect material was described and sampled. Samples were collected according to procedures established by EPA in 40 CFR 763. Samples were sent to EMSL and AAL for analysis. Upon arrival at the laboratory, the samples were logged-in and stored for analysis. Analyses were performed using the polarized light microscopy (PLM) method of asbestos detection using guidelines and procedures established in the Method for the Determination of Asbestos in Bulk Building Materials (EPA-600/R July, 1993). Results were provided as percent (%) asbestos by volume. Samples found to contain greater than 1% asbestos were considered positive and listed as ACM. Sample found by this method to have less than 1% were further analyzed by EPA method 400 Point Count Procedure. The point counting allowed for a more accurate determination and results were provided as % asbestos by volume. LIMITATIONS OF SURVEY This asbestos inspection report has been prepared by EE&G in a manner consistent with industry standards exercised by members of the profession practicing under similar conditions. No other warranty, expressed or implied is made. The intent of this survey report is to assist the owner or client in locating ACM. Under no circumstances is this survey to be utilized as a proposal or a project specification document without the expressed written consent of EE&G. The survey was conducted to identify suspect ACM in accessible interior, exterior, and roofing areas of the subject areas. If other areas at this location are to be impacted during planned or future renovations, a separate asbestos survey of these areas will be required. Some ACM may not have been discovered due to inaccessibility or missing/incomplete plans. Suspect materials discovered subsequent to the issue of this survey report should be sampled and analyzed to determine asbestos content and to initiate appropriate responses.

3 Mr. Jeffrey Barrow March 2, 2018 Page 3 Analyses were carried out by PLM. While the most commonly accepted analytical method for detecting asbestos in bulk materials, PLM is known to have limited resolution and may not detect extremely small asbestos fibers. Certain materials, notably vinyl floor tiles, may contain extremely fine asbestos fibers that are beyond the resolution of PLM. EE&G's interpretations and recommendations are based upon the results of sample collection and analyses in compliance with environmental regulations, quality control and assurance standards, and the scope of work as indicated in EE&G s proposal. The results, conclusions, and recommendations contained in this report pertain to conditions observed at the time of the survey. Other conditions elsewhere in the subject building(s) may differ from those in the inspected/surveyed locations and, such conditions are unknown, may change over time, and have not been considered. This report was prepared solely for the use of EE&G s client, and is not intended for use by third party beneficiaries. The client shall indemnify and hold EE&G harmless against liability for loss arising out of or relating to reliance by a third party on work performed thereunder, or the contents of this report. EE&G will not be held responsible for the interpretation or use by others of data developed pursuant to the compilation of this report, or for use of segregated portions of this report. SURVEY AREA DESCRIPTION AND OBSERVATIONS Former Manor Building The three-story building was comprised of concrete block construction on pilings. The interior walls were observed to be finished with a drywall system and/or plaster. The ceiling was observed to be finished with drop in ceiling tiles, plaster, or popcorn ceiling texture. The floors were finished with vinyl floor tile over concrete slab. The heating, ventilation and air cooling (HVAC) ductwork was observed to be insulated sheet metal and insulated flex duct. Plumbing components were observed not to be insulated with suspect material. Fire proofing was not present in the subject area. The exterior walls were observed to be finished with stucco and paint. The roof was observed to be finished with a field membrane and 6 parapet walls; and mansard overhangs with flets and decorative barrel tiles. EE&G reviewed Client provided plans (attached) in order to determine building materials likely to be impacted during the demolition. Upon review, EE&G designed this survey to include and be limited to sampling of the interior and exterior walls, floors, ceilings, HVAC components, and roofing components.

4 Mr. Jeffrey Barrow March 2, 2018 Page 4 RESULTS Asbestos-containing materials (ACM) Asbestos was found in amounts greater than 1 percent in the following materials and therefore are considered ACM: Manor Building: Black parapet wall flashing system consisting of nonacm 90/30lb felts with ACM seam, cap and nailhead (2-5%) - Approximately 660 linear feet/5,300 square feet (SF) around upper inner perimeter and cap, and lower curb/kant system.. Black mansard wall flashing system consisting of nonacm 90/30lb felts with ACM seam, cap and nailhead (below barrel tiles) - Approximately 700 linear feet/7,000 square feet (SF) around outer upper perimeter and sout lower overhangs. Black roof field membrane - approximately 100SF in a roof patch located towards the north central end of the roof. Pink sink undercoating - 4 sets of 2 deep sinks located in the Utilities areas on the floors. MARATHON HS MANOR&14 DEMO SURVEY REV 0318

5 Mr. Jeffrey Barrow March 2, 2018 Page 5 Nonasbestos-containing materials Asbestos was not detected in the following materials: Brown barrel tile concrete shingles. Black parapet wall and mansard felts (30lb under felt) Black/grey parapet wall and mansard felts (90lb top felt) Black built-up roof field membrane (w/gravel). Gray plaster system. Gray exterior stucco with paint. White popcorn ceiling texture. White DWS. White 2 x 4 laminate CT. Gray 2 x 2 dot grove CT. Gray 2 x 4 dot groove CT. White HVAC mastic. Gold HVAC mastic. Beige VCB. Blue VCB. Beige linoleum. Beige 12x12 VFT with mastic. Orange 12x12 VFT with mastic. Black felt paper. White field membrane. Gray cinder block. Gray concrete. White sink undercoat. The original laboratory reports from 2015, 2017 and 2018 area attached. CONCLUSIONS The black parapet wall, black field membrane, and pink sink undercoat were found to be ACM. If other specific areas at this location are to be impacted during planned demolitions, an asbestos survey of these areas will be required. Suspect materials discovered after this inspection should be sampled and analyzed to determine asbestos content and to initiate appropriate responses. RECOMMENDATIONS FOR CATEGORY I NONFRIABLE ACM Manor Building: Black parapet wall flashing system consisting of nonacm 90/30lb felts with ACM seam, cap and nailhead (below barrel tiles) around upper inner perimeter and cap, and lower curb/kant system. Black mansard wall flashing system consisting of nonacm 90/30lb felts with ACM seam, cap and nailhead (below barrel tiles) Black field membrane on the northern central patch section.

6 Mr. Jeffrey Barrow March 2, 2018 Page 6 Pink sink undercoat in the first and second floor soiled utility rooms of the Manor building. These nonfriable materials must be removed prior to activity that would release asbestos fibers from these materials. Specifically, demolition activity that will crush, abrade, or dissolve the matrix of these materials must be performed by a Florida-licensed Asbestos Contractor. ADDITIONAL RECOMMENDATIONS If other structures at this location are to be impacted during demolition, an asbestos survey of these structures will be required. Suspect materials discovered after this inspection should be sampled and analyzed to determine asbestos content and to initiate appropriate responses. Demolition activities shall be conducted in accordance with 40 CFR 61 (NESHAP). It is recommended that contractor personnel receive a copy of EPA guidance on wet methods for asbestos removal and demolition, as well as the EPA guidance document on demolition practices under the asbestos NESHAP. A licensed asbestos consulting firm should perform final air monitoring of the renovation areas after asbestos removal to document the air quality, perform daily inspections, and provide final visual inspections and final air clearance testing. EE&G recommends a walk-through of the property with the owner/owners representative and the demolition contractor prior to commencement of demolition activities. The demolition contractor should be provided the Pre- Demolition Survey Report, and should inspect the property for unidentified ACM. Unidentified suspect ACM should be sampled and analyzed prior to the start of demolition activities. Prior to demolition activities, the property should be inspected for all potentially hazardous materials. The identified materials should be removed from the property, and properly disposed of in accordance with federal, state, and local regulations. EE&G recommends a hazards communications program be implemented to protect workers in other trades from inadvertent exposure to asbestos fibers during the renovation. The Monroe County Department of Environmental Protection (MCDEP) requires notification of intent to abate ACM and/or demolish the structure. In each case, notification must be sent at least 10 working days prior to the start of any demolition activities. The general contractor should also keep a copy of this survey at the demolition site during the entire project as proof of compliance with 40 CFR 61 (NESHAP).
