1 EXECUTIVE SUMMARY

Professional Service Industries, Inc. (PSI), an Intertek Company, was retained by St. Mary’s County Public Schools (SMCPS), to conduct a limited survey for asbestos-containing materials (ACM) within five SMCPS schools located in St. Mary’s County, Maryland. The survey was conducted on April 4, 2019 by PSI’s Mr. Rinzova Renthlei and Mr. Omar Sanchez.

PSI understands that SMCPS is planning renovations and/or maintenance at the Fairlead Academy I, Fairlead Academy II Mobile Unit, Green Holly Elementary School, Town Creek Elementary School and Dynard Elementary School. SMCPS is considering replacement of flooring, windows and walls in several classrooms, offices and areas within these schools.

The purpose of the investigation and sampling was to provide information regarding the presence, condition, and estimated quantity of accessible interior, exterior ACMs, located within the facilities prior to its planned renovation.

The scope included the interior and exterior of the school buildings.

Asbestos Survey

A total of 98 samples were collected from the five referenced schools during the asbestos survey and analyzed by polarized light microscopy (PLM). The U.S. Environmental Protection Agency (EPA) and the U.S. Occupational Safety and Health Administration (OSHA) define an ACM as any material containing greater than one percent (>1%) asbestos.

The following ACMs were identified through PLM analysis during this investigation:

Fairlead Academy II Mobile Unit

• Insulation behind metal external wall (HM #02) – Located on the exterior wall of the mobile unit

Green Holly Elementary School

• 12”x 12” white vinyl floor tile and associated black mastic (HM #03) – Located in the Staff Lounge

• Floor tile (HM #07) – Located in the Assistant Principal’s Principal’s Office, underneath the carpet

• Floor tile with mastic (HM #10) – Located in Judy Center Offices, underneath the carpet

• Floor tile with mastic (HM #14) – Located in Classroom 8

Town Creek Elementary School

• Window glazing (HM #01) – Located in the Principal’s Office

• Window glazing (HM #02) – Located in the interior of Main Hallway

2 INTRODUCTION

2.1 SCOPE OF SERVICES

The scope of services consists of conducting a limited ACM survey at following schools:

• Fairlead Academy I (20833 Great Mills Road, Lexington Park, MD 20653)

• Fairlead Academy II Mobile Unit (24009 Point Lookout Road, Leonardtown, MD 20650)

• Green Holly Elementary School (46060 Millstone Landing Road, Lexington Park, MD 20653)

• Town Creek Elementary School (45805 Dent Drive, Lexington Park, MD 20653

• Dynard Elementary School (23510 Bushwood Road, Chaptico, MD 20621)

PSI understood that SMCPS was planning renovations and/or maintenance at the referenced subject schools.

SMCPS is considering replacement of flooring, windows and walls in several classrooms, offices and areas within the schools. Per the client’s request, the following areas were requested for the limited asbestos survey:

• Fairlead Academy I – Sampling was requested for ceiling drywall/plaster in ceiling of the Faculty Lounge.

• Green Holly Elementary (GHES) – Sampling was requested for flooring, which is a combination of tile and carpet, along with baseboard mastic tested for flooring replacement plans. The survey will involve the office suite and eleven (11) additional rooms tested to determine if abatement is necessary.

• Town Creek Elementary – Sampling was requested for Window glazing needs to be tested in four (4) rooms prior to window replacement.

• Dynard Elementary - Storage closet wall and flooring in a classroom slated for renovation to convert to a "time out" room. The flooring was previously abated; however, testing was to be performed in areas around cabinets and a counter that will be removed.

• Fairlead Academy II Mobile Unit - This is a "quad" mobile unit. Previous signs in mobile units state

"inaccessible wall areas contain asbestos". Sampling of the wall was requested to confirm whether the wall materials are ACM or not. Mobile units slated for smart board installation onto walls that will require fasteners being attached into walls were to be tested.

The investigation was conducted with the understanding that these materials are being assessed for purposes of Environmental Protection Agency (EPA) and Occupational Safety and Health Administration (OSHA) compliance during building renovation activities.

2.2 PURPOSE

The purpose of this survey was to provide general information for the referenced subject properties regarding the presence, condition, and quantity of accessible and/or exposed friable and non-friable, building materials that contain asbestos, prior to the planned demolition of the building.

2.3 AUTHORIZATION

Authorization to perform this work was given on March 26, 2019 by Ms. Stacy Suite, Operations Coordinator of SMCPS. The project was conducted in accordance with the scope, terms and conditions of PSI’s signed Proposal No. 0448-272999, dated March 22, 2019.

2.4 LIMITATIONS

Asbestos

This asbestos survey was intended to meet the requirements of the EPA National Emission Standards for Hazardous Air Pollutants (NESHAP) for Asbestos demolition or renovation. The survey included a thorough inspection of accessible interior, exterior and roof areas of the subject property prior to demolition.

The survey included the interior and exterior of the referenced facilities.

Destructive sampling, such as behind finished surfaces (plaster/drywall walls, above hard ceilings, etc.); inside mechanical chases, behind mirrored walls, under carpet or tiled floors, etc., was generally conducted to try to assess inaccessible or concealed materials. Void spaces which were evaluated included locations of suspected pipe or HVAC chases, wall cavities where fireproofing or other ACM was suspected, above finished ceiling systems where ACM was likely to exist, within pipe trenches or within concealed locations. Although PSI made an attempt to identify all areas of ACM, an exhaustive investigation of void spaces was not included in the scope of services for this project. There may exist conditions which were unable to be identified within the scope of this survey.

Inaccessible is defined as areas of the building that were locked, or where admittance was not permitted. It also includes areas/materials that could not be tested (sampled) without destruction of the structure or a portion of the structure, and areas/materials that could not be safely reached by the inspector or inspection team. In the event that access to a portion of the building was not obtained (which otherwise would have been tested), such limitations specifically are identified in the Findings Section of this report.

PSI did not sample any system which presented a hazard to the inspection team such as energized electrical systems or within confined spaces.

PSI did not collect samples from building elements where the intended use would be compromised by testing, such as fire rated doors, vapor barriers, mirror mastics, etc.

2.5 WARRANTY

The field and laboratory results reported herein are considered sufficient in detail and scope to determine the presence of accessible and/or exposed suspect ACM associated with the building structure. PSI warrants that the findings contained herein have been prepared in general accordance with accepted professional practices at the time of its preparation as applied by professionals in the community. Changes in the state of the art or in applicable regulations cannot be anticipated and have not been addressed in this report.

The survey and analytical methods have been used to provide the client with information regarding the presence of accessible and/or exposed suspect ACM existing at the time of the inspection. Test results are valid only for the material(s) tested. There is a distinct possibility that conditions may exist which could not be identified within the scope of the study or which were not apparent during the site visit. This inspection covered only those areas that were exposed and/or physically accessible to the Inspector. The study is also limited to the information available from the client at the time it was conducted.

As directed by the client, PSI did not provide any service to investigate or detect the presence of moisture, mold or other biological contaminants in or around any structure, or any service that was designed or intended to prevent or lower the risk of the occurrence of the amplification of the same. Client acknowledges that mold is ubiquitous to the environment with mold amplification occurring when building materials are impacted by moisture. Client further acknowledges that site conditions are outside of PSI’s control, and that mold amplification will likely occur, or continue to occur, in the presence of moisture. As such, PSI cannot and shall not be held responsible for the occurrence or recurrence of mold amplification.

No other warranties are implied or expressed.

3 METHODOLOGY

Inspection and sampling procedures were performed in general accordance with the guidelines published by the EPA. The inspection and survey described below was performed by EPA accredited and State of Maryland licensed inspectors. The asbestos inspection and sampling were conducted on April 4, 2019 by PSI asbestos inspectors Mr.

Rinzova Renthlei (MD License # 18036011) and Mr. Omar Sanchez (MD License # 18025231)

3.1 RECORD DOCUMENT REVIEW

Prior to conducting the visual inspection, PSI reviewed documents provided by the client, including drawings, floor plans, historical data, maintenance records, previous survey reports, laboratory reports, etc. for information regarding construction history and building materials.

• No prior documentation was provided to PSI prior to the site survey.

3.2 ASBESTOS SURVEY METHODOLOGY

Inspection Procedures

An initial individual building structure walkthrough was conducted to determine the presence of suspect asbestos-containing materials that were accessible and/or exposed within the interior of the buildings.

Destructive investigation, such as behind finished surfaces (plaster/drywall walls, above hard ceilings, etc.); inside mechanical chases, behind mirrored walls, under carpet or tiled floors, etc., was generally conducted in a limited fashion to try to assess inaccessible or concealed materials. The inspection team selected a few representative areas to perform an intrusive evaluation of void spaces within the building or structure. Such inspections were made by creating an opening of sufficient size to determine the presence, condition and quantity of suspect ACM within. Void spaces which were evaluated included locations of suspected pipe or HVAC chases, wall cavities where fireproofing or other ACM was suspected, above finished ceiling systems where ACM was likely to exist, within pipe trenches or within concealed locations. Although PSI made an attempt to identify all areas of ACM, an exhaustive investigation of void spaces was not included in the scope of services for this project. There may exist conditions which were unable to be identified within the scope of this survey. PSI did not collect samples from building elements where the intended use would be compromised by testing, such as fire rated doors, vapor barriers, mirror mastics, etc.

Materials which were similar in color, texture, general appearance and which appear to have been installed at the same time were grouped in Homogeneous Sampling Areas. Such materials are termed "homogeneous materials" by the EPA. During this walkthrough, the approximate locations of these homogeneous materials were also noted.

The inspector evaluated the overall condition of the material and determined whether the materials were friable or non-friable by touching the material, where practical. A friable material is defined as any material able to be crushed, crumbled, pulverized or reduced to a powder by hand press when dry.

Each material was further assessed for overall condition. Conditions were rated as good, damaged or significantly damaged. PSI’s inspector also identified the EPA classification of the material: Regulated ACM (RACM), Category I non-friable ACM, and Category II non-friable ACM, based on the materials current condition. PSI’s inspector provided estimated quantities of the materials identified as ACM, based only on materials that were accessible and exposed.

Sampling Procedures

Following the walkthrough, the Inspector collected samples of suspect materials.

EPA guidelines were used to determine the sampling protocol. Sampling locations were chosen to be representative of the homogeneous sampling area. While an effort was made to collect samples randomly, samples were taken preferentially from areas already damaged or areas which were the least visible to minimize disturbance of the material.

Each sample location was sprayed with amended water and was kept wet during the entire sampling process.

Samples were collected by coring through the material from the surface down to the base substrate. All layers of the material were extracted in placed into a sample container for transport to the laboratory. Sample containers were sealed and labeled with a unique sample identification number. Where appropriate, sampled materials were sealed with an encapsulant or covered with tape after sampling. PSI is not responsible for restoring the sampled areas to their pre-sampled condition.

Laboratory Analysis

All samples were analyzed at PSI’s Asbestos Laboratory located at 850 Poplar Street, Pittsburgh, Pennsylvania 15220.

The PSI Pittsburgh Asbestos Laboratory is a National Voluntary Laboratory Accreditation Program (NVLAP) Accredited (#101350-0) and an American Industrial Hygiene Association (AIHA) Accredited (#8222) Laboratory. A copy of the Laboratory’s Accreditation Certificate is included in Appendix C.

The samples were analyzed for asbestos on a “positive-stop” basis by polarized light microscopy (PLM) in accordance with the “EPA Method for the Determination of Asbestos in Bulk Building Materials” (EPA/600/R-93/116 July 1993).

Analysis was performed by visually observing the bulk samples with a stereoscope followed by slide preparation(s) for microscopic examination and identification.

Using a stereoscope, the microscopist visually estimated relative amounts of each constituent by determining the volume of each constituent in proportion to the total volume of the sample. Next, the samples were mounted on slides and then analyzed for asbestos (chrysotile, amosite, crocidolite, anthophyllite, actinolite/tremolite), and fibrous non-asbestos constituents (mineral wool, fiberglass, cellulose, etc.). Asbestos was identified by refractive indices, morphology, color, pleochroism, birefringence, extinction characteristics, and signs of elongation. The same characteristics were used to identify the non-asbestos constituents.

The EPA method allows samples which are visually determined to have less than 10% asbestos to be quantified using a Point Count procedure. An ocular reticule (cross hair or point array) is used to visually superimpose a point or points on the microscope field of view. A total of 400 points superimposed on either asbestos fibers or non-asbestos matrix material must be counted over at least eight different preparations of representative subsamples. If an asbestos fiber and matrix particle overlap so that a point is superimposed on their visual intersection, a point is scored for both categories. Point counting provides a quantification of the area percent asbestos. No samples were point counted for this survey.

4 FINDINGS

4.1 ASBESTOS RESULTS

PSI collected a total of 98 samples from 32 suspect homogenous materials (HM) from the five SMCPS schools included in this project. Table 1,2,3,4 and 5 lists the materials that were sampled, along with the results of the inspection and laboratory analysis.

Laboratory analysis indicated that asbestos was detected in some of the samples collected from the referenced subject schools.

PSI did not observe any assumed ACMs within the facility.

The “Report of Bulk Sample Analysis for Asbestos”, Sample Location diagram and Photographs are included in the Appendices. The Tables on the following pages list the suspect asbestos-containing materials observed throughout the building. Table 1 lists the materials that were sampled, along with the results of the inspection and laboratory analysis. Both tables give a description of the materials, their general locations, condition, friability, EPA NESHAP Category, and estimated quantity for abatement.

Inaccessible Areas

PSI did not encounter any inaccessible areas.

Regulatory Guidelines

ACM Definition - The EPA & OSHA consider a material to be asbestos-containing if at least one sample from the homogeneous area shows asbestos in an amount greater than 1%.

Point Count Quantification - If a material is found to contain less than 10% asbestos via visual estimation, it can be treated as non-ACM per EPA Regulations, if verified to contain 1% or less asbestos by the Point Count Quantification Procedure. If not point counted, a sample in which asbestos was visually detected and estimated (including trace to ≤1%) must be assumed to be greater than 1% and treated as ACM. Please refer to the laboratory analyses for a more detailed description of the microscopic analysis of individual samples. No samples were quantified by the Point Count Procedure in this Asbestos Survey.

EPA NESHAP Category - EPA classifies ACM into the following categories:

• RACM is any (a) Friable asbestos material, (b) Category I non-friable ACM that has becomes 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.

• Category I Non-friable ACM includes packings, gaskets, resilient floor covering, and asphalt roofing products which contain more than one percent asbestos.

• Category II Non-friable ACM includes any material, except for a Category I non-friable ACM, which contains more than one-percent asbestos and cannot be reduced to a powder by hand pressure when dry.

OSHA –

OSHA requires all suspect materials to be analyzed by layer, even materials such as drywall/joint compound, which may sometimes be composited per the EPA. If any layer contains asbestos in a concentration >1%, the material is considered an ACM.

OSHA has a classification system (I thru IV) for ACM depending on the type of material and the disturbance as follows:

• ‘Class I’ work is defined as activities involving the removal of ACM or presumed ACM (PACM) that is thermal system insulation (TSI) and surfacing materials.

• ‘Class II’ activities involve removal of ACM/PACM other than TSI or surfacing material.

• ‘Class III’ work includes repair and maintenance operations which are likely to disturb ACM/PACM.

• ‘Class IV’ work includes maintenance and custodial activities during which employees contact but do not disturb ACM/PACM.

Materials where asbestos is detected, but where point counting is conducted and determined that the concentration is ≤1% asbestos, are not considered to be ACM by OSHA. However, these materials are considered unclassified asbestos work per OSHA. Some OSHA work control practices and prohibitions will still apply, with the extent depending on whether the worker's exposure to airborne asbestos exceeds the OSHA permissible exposure limit

(PEL).

Additional details of the OSHA asbestos regulations related to the construction industry can be found in 29 CFR part 1926.1101.

Quantification

Quantification of suspect asbestos-containing materials was conducted using visual estimation by a licensed asbestos inspector. This visual estimation was performed in accordance with generally accepted practices in the asbestos industry based on materials that were accessible and exposed. These values are sufficiently accurate for the purpose of documenting the presence of asbestos within its space for the purpose of identifying abatement control conditions or for general policy considerations. Actual quantities may differ between visually estimated values and physical measurements. If a licensed asbestos abatement contractor is engaged to remove asbestos containing materials, the abatement contractor is responsible for verifying reported quantities of ACM.

5 CONCLUSIONS & RECOMMENDATIONS

5.1 CONCLUSIONS

ACMs were found within Fairlead Academy II Mobile Unit, Green Holly Elementary School and Town Creek Elementary School.

PSI did not observe any assumed ACMs in the inspected schools.

Materials with low concentrations of asbestos (trace to 1%) were not identified in the inspected schools.

5.2 RECOMMENDATIONS

The identified ACM should be maintained in a good non-damaged condition through use of an Operations and Maintenance (O&M) program if they are to remain in place.

The identified ACMs found in Green Holly ES (HM #03, 07, 10 & 14), and Town Center ES (HM #01 & 02) are considered Category I and Category II non-friable ACM as per EPA NESHAP 40 CFR, Part 61, Subpart M. They do not pose a significant exposure problem unless sawn, drilled, sanded, or structurally altered in a way, which could make them become friable. Prior to any renovation/demolition, which may impact these materials, a certified asbestos abatement contractor utilizing proper removal techniques should remove and dispose of them. PSI recommends using wet removal methods with documentary air monitoring to verify compliance with the NESHAP Regulations.

The identified ACMs found in Fairlead Academy II Mobile Unit (HM #02) is considered to be friable, therefore RACM. "Friability" refers to the propensity of a material to crumble under hand pressure when dry. Friable ACM are more likely to release asbestos fibers into the environment than non-friable ACM and are therefore considered more hazardous. Prior to any renovations/demolition, which may impact these materials, a certified asbestos abatement contractor utilizing proper removal techniques should remove and dispose of them. PSI recommends a full containment with wet removal methods and documentary air monitoring to verify compliance with the NESHAP regulation.

In addition, prior to any future maintenance, renovation, or demolition activities, any newly discovered suspect ACMs or previously identified materials that were not sampled in the renovation location should be tested. Any areas that were noted as being inaccessible during this project or any concealed areas, such as behind walls, where suspect ACMs are discovered, will require a survey for ACM. If, during demolition or renovation activities, and previously unidentified suspect ACMs are discovered in concealed areas, such as behind walls, they should be sampled for asbestos or they must be treated as ACM.

Prior to the initiation of a project that would involve abatement, a detailed engineering cost estimate and project design is recommended. The engineering cost estimate will incorporate such variables as scheduling and phasing of the project, the size, and extent of the project, seasonal factors, operation factors, and other restrictions, respiratory protection, alternate abatement options, and type of replacement material. An engineering cost estimate would also include professional fees, such as for project design and management, and other expenses, such as on-site air monitoring and construction supervision.

Report Notes: (PT) Point Count Results

Quantitation is based on a visual estimation of the relative area of bulk sample components, unless otherwise noted in the "Comments" section of this report. The results are valid only for the item tested. This report may not be used to claim product endorsement by NVLAP or any agency of the U.S. Government. Method used: E.P.A.

Interim Method for the Determination of Asbestos in Bulk Insulation Samples (EPA 600/M4-82-020). Polarized Light Microscopy is not consistently reliable in detecting asbestos in floor coverings and similar non-friable organically bound materials. Quantitative Transmission Electron Microscopy is currently the only method that can be used to determine if the material can be considered or treated as non-asbestos containing. Samples will be disposed of within 30 days unless notified in writing by the client. No part of this report may reproduced, except in full, without written permission of the laboratory. The reporting limit is 1% by weight. NVLAP Lab Code 101350-0.
