48 ENVIRONMENTAL SERVICES, LLC 253 Delk Road, Hattiesburg, MS Phone (601) Fax (601) EXECUTIVE SUMMARY Environmental Services, LLC was retained, Eric Morris, of the City of Picayune, 203 Goodyear Blvd, Picayune, MS 39466, for an asbestos roof inspection on the Police Department Building, located at 328 South Main Street, Picayune MS The survey was completed on September 7, Joe Venus, an MDEQ certified asbestos inspector (License #ABI ), of Environmental Services, LLC did the inspection. The purpose of the survey was to verify the presence, extent, and condition of asbestos containing materials (ACM), in the referenced buildings above. The asbestos survey was performed in accordance with applicable Local, State, and Federal regulations. During the survey, six (06) Homogenous Areas was discovered with a total of fourteen (14) samples collected. The analytical results indicated that zero (0) collected samples detected concentrations of asbestos. The Laboratories Analytical Results are located in Appendix A of this report. 1.1 Asbestos Containing Material Summary The analytical results of the bulk samples collected during the site survey identified the following materials, with any concentrations of asbestos. Suspect materials with greater than 1% asbestos are considered to be an asbestos containing material by Mississippi Department of Environmental Quality (MDEQ) and Environmental Protection agency (EPA). OSHA references worker protection guidelines for exposure to any amounts of asbestos, even below the >1% recognized by the EPA and State Regulators. Listed below are samples that contain any amounts of asbestos. Table 1 has the survey results of all samples collected. Positive Asbestos Containing Materials (ACM), Police Department Bldg Roof, Picayune Homogeneous Area/Location Sample Number Material Sampled, Condition No samples collected contained asbestos materials Asbestos Content NESHAP Category Square footage

49 Environmental Services, LLC City of Picayune Page PROJECT SUMMARY Joe Venus, a certified asbestos inspector, is accredited through the State of Mississippi Department of Environmental Quality (MDEQ). He has successfully completed Environmental Protection Agency approved training in asbestos inspection and removal, and participates in ongoing training offered by accredited associations. His MDEQ Certification Number is I Copies of these certifications and MDEQ notifications are found in Appendix B at the end of this report. Upon arriving at the Site, Mr. Venus did a short tour of the overall Site. He observed the suspect ACM material to be sampled and assigned a Homogeneous Area (HA) number, description, and measurement to the suspect materials. Homogeneous Areas are defined as suspect materials similar in color, texture, and apparent age of application. 2.1 Asbestos Survey Protocol The ACM inspection was preformed in accordance with the U.S. Environmental Protection Agency (USEPA) requirements for implementation of the Asbestos Hazard Emergency Response Act (AHERA), and the Asbestos School Hazard Reauthorization Act (ASHARA). The technique used for sampling the suspected materials was designed to minimize possible fiber release and in turn possible contamination of surrounding areas. The MDEQ guide to suspect asbestos containing materials includes all building materials, except, unpainted glass, unpainted wood, and unpainted metals. All representative suspect materials sampled were collected in accordance with EPA s AHERA and Guidance for Controlling Asbestos Containing Materials in Buildings (EPA 560/ , June 1985). The sample location is sprayed with amended soapy water mixture when applicable. Then, a core sample of material was collected and properly stored, in a labeled airtight bag. The chain of custody form was completed for bulk samples collected and subsequently delivered to Environmental Hazards Services Laboratories (a certified NVLAP laboratory) for analysis using Polarized Light Microscopy (PLM). Environmental Hazards Services utilizes the dispersion staining technique according the U. S. EPA method 600/M4-82/020 incorporating visual estimates of identified material percentages. This survey was to identify any of the six major types of asbestos, Chrysotile, Amosite, Crocidolite, Anthophylite, Tremolite, and Actinolite in the materials sampled. During the sampling activities, each suspect ACM was touched by the inspector to determine its friability and observed to determine the physical condition of the material. A friable material is a material is defined as a material that can be crumbled, or reduced to a power by hand pressure. Friability of a material directly relates to a potential of the ACM to release airborne fibers. The inspector assessed the suspect ACM, according to its physical condition. The results of this inspection may not be considered to be a product endorsement by Environmental Services, LLC, NVLAP, or any agency of the U.S. Government. Environmental Services, LLC recommends that the identified ACM should be either managed in place with an Operations and Maintenance (O&M) Plan, or abated by a licensed contractor in accordance with all applicable local, State and Federal rules and regulations. Should additional suspect materials not included in this survey be discovered during maintenance or renovation activities, Environmental Services, LLC recommends that samples of these materials be tested for asbestos content.

50 Environmental Services, LLC City of Picayune Page Asbestos Survey Findings The analytical results of the bulk samples collected during the site survey, September 7, 2017 identified materials with any concentrations of asbestos. Suspect materials with greater than 1% asbestos are considered to be an asbestos containing material by Mississippi Department of Environmental Quality (MDEQ) and Environmental Protection agency (EPA). OSHA references worker protection guidelines for exposure to any amounts of asbestos, even below the >1% recognized by the EPA and State Regulators. Table 1 has the survey results of all samples collected. Appendix A has the Laboratories Analytical Results. During the survey, six (06) Homogenous Areas was discovered with a total of fourteen (14) samples collected. The analytical results indicated that zero (0) collected samples detected concentrations of asbestos. The Laboratories Analytical Results are located in Appendix A of this report. 2.3 Limitations This survey was completed in accordance with Federal and State protocols for identifying the presence of asbestos-containing materials. Environmental Services, LLC or the inspector does not warrant that all asbestos containing materials have been located or identified during this inspection. Other suspect ACMs may be present in areas not visible or readily accessible to Environmental Services, LLC at the time of the survey. Additionally, prior renovation or repair activities may have altered building materials such that suspect ACM could not be properly identified by the inspector. Should additional suspect ACMs be identified, they should be assumed to contain asbestos and sampled for asbestos content. The person or persons in charge of the facility should exercise care, any time a suspect material is to be disturbed, which has not been sampled or assumed to contain asbestos. The liability of Environmental Services, LLC is limited to the amount paid by the client for this report. The client assumes all responsibility for the further distribution of this report and its contents. By making such distribution the client agrees to hold Environmental Services, LLC harmless against all claims of persons so informed of the contents hereof. The amount of ACM listed in this report is an approximation based upon field observations and/or limited measurements. A Licensed Asbestos Management Planner prior to development of an O&M Plan should determine the actual quantity of ACM requiring management. Similarly, a Licensed Asbestos Consultant prior to initiation of abatement activities should verify the quantity of ACM requiring abatement. The inspection date was September 7, Any changes occurring after this date can alter the data in this inspection report.

51 Environmental Services, LLC City of Picayune Page Positive Sample Results Table 1 Please see Appendix A (lab report), attached, for detailed composition of materials. Results of samples taken from any location may be considered the same for identical materials in other areas of these buildings. Police Department Roof, Picayune MS Sample # Description Results Samples collected did not contain asbestos materials

52 Environmental Services, LLC City of Picayune Page DATA SUMMARY Based on the Asbestos Inspection, Environmental Services, LLC, offers the following; no asbestos-containing material (ACM) were identified as a result of this limited investigation on the Police Department s roofing materials. 3.1 Procedures for Renovation and Demolition If renovation to the buildings' interior or exterior should occur and these actions directly affect the physical condition of any or all of the ACMs, then abatement of these materials should be performed before such activities begin. If abatement (removal, repair, enclosure or encapsulation) actions should occur, the building owner or operator should comply with the following requirements: a. Mississippi Department of Environmental Quality (MDEQ) should be notified of planned renovation or demolition activities at least 10 working days prior to the scheduled start of these activities, as required by EPA 40 CFR Part (a) and (b) b. The Occupation Safety and Health Administration's (OSHA) Right-to- Know regulation requires the contractor to advise all workers of the presence of asbestos in the area in which they are working and to inform them of the nature of the hazard involved with exposure to asbestos. Should any regulated or non-regulated ACM be allowed to remain in these buildings, an Operational and Maintenance (O&M) Plan should be developed so that administration and maintenance personnel can monitor the physical condition of the ACM. If you should have any questions about this limited asbestos inspection, please contact me at the letterhead address and phone number. Joe Venus, Jr.

Lightweight Concrete over Metal Deck. 2. Lightweight Concrete over Structural Concrete Deck. B. Contractor should include at least provisions to repair 15% of entire existing roof decking in Base Bid (including lightweight concrete and metal deck) RELATED SECTIONS A. Section Rough Carpentry B. Section Modified Bitumen Membrane Roofing 1.03 SYSTEM (where applicable) A. Remove damaged and unacceptable lightweight concrete material (down to the metal or structural concrete decking). Install in the void lightweight insulating concrete patching compound sufficient to bring the repaired area level with the existing lightweight concrete deck. PART 2 - PRODUCTS 2.01 MATERIALS: A lightweight insulating concrete patching compound incorporating cementitious binders, low density fine aggregates, and additives supplied by a single manufacturer. A. Zono-Patch Lightweight Insulating Concrete Patching Compound by Siplast, Inc. Irving, TX (800) B.

The record drawings indicate that portions of the lightweight concrete deck s top surface are sloped for drainage. Verify that slope is present and inform Professional. Dungan Engineering, P.A c122

92 SECTION EXISTING DECK REPAIR C. Inspect existing deck after removing roof membrane. Identify all wet and otherwise damaged areas. D. All deck areas must pass a 40# fastner retention test. Remove all areas that fail DEMOLITION / PREPARATION A. Remove wet and otherwise damaged areas of lightweight concrete. Remove debris from the area and remove deteriorated roof deck material down to a sound substrate. Areas shall be neatly and squarely cut. B. For improved bonding, moisten the existing lightweight insulating concrete surface with water or a 1:1 dilution of acrylic or PVA concrete bonding agent. The extent of moistening will depend on the nature of the surface to be repaired. Highly porous, dusty surfaces will require more preparation. If moistening is insufficient, the Zono-Patch will stiffen too quickly to finish MIX DESIGN/PRODUCT PREPARATION 3.04 APPLICATION 3.05 CLEAN UP A. One five gallon container of Zono-Patch requires approximately 3 gallons of water for mixing. For larger quantities, utilize a mix ratio of 5 parts Zono-Patch powder to 3 parts water. The quantity of water may be adjusted to control the consistency and handleability of the material during application. Adding more water will make the product more fluid; less water will make it stiffer. Sufficient water should be added to create a wet mix that is easily trowelled and finished to a smooth surface. B. In a suitable container or mortar mixer, add water in a quantity suitable to achieve the desired batch size. Add dry Zono-Patch powder to the water and mix until the wet slurry is of a smooth, lump-free, creamy consistency. If a container is used, a jiffy mixer attached to a drill motor is recommended. A. Following mixing and utilizing product that has the proper stiffness for the specific application, pump or pour the Zono-Patch into place. Finish the surface of the Zono- Patch to a smooth surface. B. Trowel finish any edges to provide a smooth transition to the surface of the existing substrate. A. Leave decks clean, flat and free of gaps or protrusions that would be unsuitable for reroofing.

123 SECTION EXISTING DECK REPAIR SBS MODIFIED BITUMEN ROOFING PART 1 GENERAL The acceptance of the structural roof deck condition by SOPREMA refers solely to condition of roof deck surface. The responsibility for the structural integrity of the roof deck system and for the proper design relationship among other building components-combined with the existing or potential interior and exterior environmental considerations-and the structural roof deck system rests solely with the design professional whether they are an architect, roof consultant, engineer or building owner or authorized building owner representative. SOPREMA reserves the right to accept or reject existing deck conditions based on their suitability for specific SOPREMA assemblies and their corresponding methods of application SUMMARY The Work generally involves providing a dual SBS membrane system with a finished surface of granules. These systems are fully adhered with Certified Type IV asphalt. Systems are typically placed over an approved insulation substrate on an approved deck type such as steel, concrete, lightweight concrete, poured or plank gypsum, wood plank or plywood wood, or cementatious wood fiber or hybrid decking complete with flashings, scuppers, expansion joints, control joints, cant strips, edge strips, crickets, insulation, and performing such incidental or other work as may be required by these operations and called for by the drawings RELATED WORK SPECIFIED ELSEWHERE: (The following item may be covered in other sections of the specifications.
