Wet clean the respirator in accordance with manufacturer’s instructions,taking care to protect battery packs and moving parts, if any.

Thoroughly wash face and hands with soap and water.

Lock-out and tag-out all power supplies to the work area and provide power froma source outside the work area that is ground fault protected.

Note: Prior to the commencement of any abatement activities, Dominion’s field supervisor willconduct a complimentary work area inspection of the regulated work area.

Ambient Air Monitoring:

• Pursuant to the requirements of OSHA Regulation 29 CFR 1926.1101, the Contractor shall monitorairborne fiber counts and worker exposure levels inside the regulated area throughout the asbestosabatement and cleaning operations.

• Copies of all air monitoring records and sample results collected by the Contractor shall be providedto Dominion within 24 hours of collection, for review.

Page -5-

• The method of air monitoring and analysis by the Contractor during abatement operations shall beconducted in accordance with OSHA Regulations 29 CFR 1926.1101, using the NIOSH 7400 methodfor Phase Contrast Microscopy (PCM).

• The laboratory used to analyze asbestos samples shall be a participant in the AIHA/NIOSH PATprogram for asbestos fiber counting and accredited by the National Voluntary LaboratoryAccreditation Program (NVLAP) for asbestos analysis by PCM.

• Personal air monitoring of Contractor Personnel is for purposes of the Contractor. It shall beperformed by the Contractor at no additional cost to CCUSD.

• Throughout the asbestos abatement and cleaning operations, area air monitoring shall be conductedby the CCUSD representative (Dominion) both inside and outside the work areas. The airborne fiberlevel outside the work area shall not exceed 0.01 fibers per cubic centimeter of air (0.01 f/cc). Theairborne fiber level inside the work area shall not exceed 0.10 f/cc over an eight hour TWA or 1.0f/cc over a 30 minute period. If any of these levels are exceeded, removal activities will stop until theair levels have been reduced and the abatement procedures have been modified. Time lost due toexcessive air concentrations is the responsibility of the Contractor. Time delays will not be grantedfor reducing fibers levels in the work areas.

• The laboratory used by Dominion to analyze asbestos samples shall be a participant in theAIHA/NIOSH PAT program for asbestos fiber counting and accredited by the National VoluntaryLaboratory Accreditation Program (NVLAP) for asbestos analysis by PCM and PLM.

• All air samples collected by the Contractor or Dominion shall be analyzed within 24 hours ofcollection.

• “Airborne Fibers” in these provisions, include all fibers regardless of composition as counted byPCM, unless additional analysis by Transmission Electron Microscopy (TEM) demonstrates to thesatisfaction of Dominion, that non-asbestos fibers are being counted.

Waste Disposal:

• Asbestos-containing and/or contaminated materials shall be provided with proper disposal at alandfill operated in accordance with the requirements of NESHAP Asbestos Regulations (40 CFRPart 61, Subpart M), and approved by EPA for asbestos wastes.

• All wastes are to be hauled by a waste hauler with all required licenses from all State and localauthorities with jurisdiction.

• All containerized waste shall be carefully loaded into fully enclosed dumpsters, trucks, or otherappropriate vehicles for transport. Care must be exercised before and during transport to ensure thatno unauthorized person(s) have access to the material. The interior of the transport vehicle shouldbe protected with two (2) layers of polyethylene plastic sheeting, each layer 6-mil thick.

• All asbestos waste shall be at a minium doubled bagged or “buritto wrapped” with two (2) layers of6-mil thick re-enforced polyethylene plastic sheeting, adequately wet, proper warning labels andgenerator labels.

• Containerized waste materials must NOT be stored outside of the work area. Take containers fromthe work area directly to a sealed truck or dumpster.

Page -6-

• Do NOT transport bagged materials on open trucks. Transport only properly sealed containersmarked with the OSHA and DOT labels in closed-bed vehicles protected with sheet plastic.

• At the disposal site, carefully unload containerized asbestos waste from the transport vehicle.Wrapped asbestos waste may require special unloading procedures and equipment. The Contractorshall ensure that all special procedures are followed, and special equipment is provided as needed.

• Retain landfill receipts and waste manifests as proof of proper disposal. Copies of all of thesedocuments shall be provided to the Owner’s Representative upon completion of the work.

• The Contractor is responsible for obtaining all required signatures on landfill disposal documents andwaste manifests. Arrangements for obtaining the Owner’s signature on these types of documents mustbe made by the Contractor sufficiently prior to scheduled transportation of the asbestos waste toensure that no delay in transporting or disposal of the waste will occur.

The conclusions and results contained herein are based solely on the information presented in thisreport. The limited sampling, testing, and observations described in the report represent conditionsonly at the specified times and locations. Additional materials or information which were hidden,undiscovered, inaccessible, or not a part of the findings presented herein, would result in themodification of the conclusions and recommendations made herein. Any response action guidelinesare based solely on the findings contained herein. The response action guidelines are presented asa courtesy and are not to be considered a complete or detailed set of specifications. Dominionperformed this survey as directed by the client and in compliance with applicable regulations.

Please note, with regard to laboratory analysis of suspect bulk asbestos-containing materials: TheEnvironmental Protection Agency (EPA) Method 600/R-93-116, Polarized Light Microscopy (PLM)is used for the testing of bulk building materials for asbestos by performing a visual estimation. Thismethod is the most widely used method for estimating asbestos in bulk building materials and workswell for most sample types. However, it might require a more detailed method such as pointcounting for accurate estimation of asbestos in samples with low asbestos concentration. Thismethod is also not applicable for samples containing large amounts of fine fibers below theresolution of the PLM (<0.3 microns). Typically, the asbestos fibers present in non-friableorganically bound (NOB) materials are often less than 0.1 microns in diameter and therefore maycause the PLM method to yield low estimates or even false negative results.

Dominion suggests that Transmission Electron Microscopy (TEM) Chatfield Semi-Quantitative EPAMethod 600/R-93-116 be used to confirm all negative results of NOB materials. This method isparticularly useful to reduce the possibility of false negatives in NOBs and to provide additionalquantitative data for samples which contain low levels of asbestos. The TEM method is availableat additional cost and is done only at the client’s request.

Dominion’s scope of service did not include the inspection for, or identification of, fungi, PCB’s,lead paint or any other hazardous or controlled substance not specifically identified herein.

Dominion is not responsible for the accuracy of information or any services provided by others, orfor conditions or consequences arising from relevant facts that were withheld, concealed,undiscovered, or not fully disclosed. Dominion is not a law firm and therefore, makes norepresentations regarding any potential liability of any person or entity for site conditions. Further,Dominion is not qualified to present medical advice. If any present or future health issues are inquestion, it is recommended that the findings in this report be presented to a qualified medicalprofessional for evaluation.

EXECUTIVE SUMMARY

EXECUTIVE SUMMARY

INTRODUCTION

This report presents the results of a limited asbestos inspection of the roofs of Buildings 100, 200,300, 400 and 500, on the Black Mountain Elementary School campus located at 33606 North 60th

Street, Scottsdale, Arizona. Pursuant to the information provided by the Cave Creek Unified SchoolDistrict #93 (CCUSD), the roofs of Buildings 100, 200, 300, 400 and 500 are scheduled forrenovation. Dominion was instructed to perform a limited asbestos inspection of the roofs ofBuildings 100, 200, 300, 400 and 500 scheduled for replacement in accordance with AHERA,OSHA, and NESHAP guidelines. Dominion was authorized to perform the asbestos inspection byverbal authorization from Mr. Mike Santina on May 11, 2018.

ASBESTOS SAMPLING

The limited asbestos inspection of Buildings 100, 200, 300, 400 and 500, was conducted on May16, 17 and May 22, 2018, by Mr. Basilio Marcos, an EPA-accredited AHERA Asbestos BuildingInspector.

A total of one hundred eight (108) bulk samples were collected from forty-three (43) homogeneousbuilding materials throughout Buildings 100, 200, 300, 400 and 500. The suspect bulk samples weresubmitted to EMLab P&K (EMLab) for analysis using Polarized Light Microscopy (PLM) methods.EMLab used the methods prescribed in Method 40 CFR, Part 763, in the Code of Federal Registerin analyzing bulk samples. EMLab is certified by the National Institute of Standards and Technologyas a National Voluntary Laboratory Accreditation Program (NVLAP), Number 500031-0. Thesuspect asbestos bulk samples were collected and submitted to the laboratory using establishedchain-of-custody procedures. Bulk samples were collected utilizing safety and health practices asrequired by the Occupational Safety and Health Administration (OSHA).

Identified in the following list, separated by building, are the forty-three (43) suspect homogeneousmaterials that were sampled during Dominion’s asbestos inspections.

RECOMMENDATIONS

Based on the previously referenced sampling data, Dominion recommends that the above listedACM identified by laboratory analysis to contain greater than one percent (>1%) asbestos-content,be properly abated by a qualified asbestos abatement contractor. The contractor should comply withall governing regulatory agencies guidelines. If any un-sampled suspect building materials arediscovered during the demolition activities, those building materials should be properly sampled bya certified inspector prior to their disturbance.

The EPA does not regulate materials reported to contain less than one percent (<1%) asbestos,however OSHA regulates all materials that contain asbestos regardless of the amount of asbestosin the material. Therefore, based on the prior stated analytical results, Dominion also recommendsthat OSHA unclassified work practices be followed for any building materials containing less thanone percent (<1%) asbestos-content that will be affected during the roof replacement activities.

All documentation is provided to CCUSD and should be retained in a permanent record. Should youhave any questions regarding the procedures that were followed during this project, please contactDominion at any time. Thank you for the opportunity to provide these environmental consultingservices.

All samples were received in acceptable condition unless noted in the Report Comments portion in the body of the report. The results relate only to the items tested. The results include an inherent uncertainty of measurement associated with estimating percentages by polarized light microscopy. Measurement uncertainty data for sample results with >1% asbestos concentration can be provided when requested.

EMLab P&K ("the Company") shall have no liability to the client or the client's customer with respect to decisions or recommendations made, actions taken or courses of conduct implemented by either the client or the client's customer as a result of or based upon the Test Results. In no event shall the Company be liable to the client with respect to the Test Results except for the Company's own willful misconduct or gross negligence nor shall the Company be liable for incidental or consequential damages or lost profits or revenues to the fullest extent such liability may be disclaimed by law, even if the Company has been advised of the possibility of such damages, lost profits or lost revenues. In no event shall the Company's liability with respect to the Test Results exceed the amount paid to the Company by the client therefor.

The test report shall not be reproduced except in full, without written approval of the laboratory. The report must not be used by the client to claim product certification, approval, or endorsement by any agency of the federal government. EMLab P&K reserves the right to dispose of allsamples after a period of thirty (30) days, according to all state and federal guidelines, unless otherwise specified.

Inhomogeneous samples are separated into homogeneous subsamples and analyzed individually. ND means no fibers were detected. When detected, the minimum detection and reporting limit is less than 1% unless point counting is performed. Floor tile samples may contain large amounts of interference material and it is recommended that the sample be analyzed by gravimetric point count analysis to lower the detection limit and to aid in asbestos identification.‡ A "Version" indicated by -"x" after the Lab ID# with a value greater than 1 indicates a sample with amended data. The revision number is reflected by the value of "x".
