CONTAINING LIGHT TUBES AND THERMOSTATS

INTRODUCTION

International Academy, Inc. (IA) was retained by Waco, Inc. to conduct a pre-demolition assessment for Hazardous Materials (user defined) requiring abatement prior to the proposed demolition of the single-family house addressed as 208 Washington Avenue, LaPlata, Maryland (herein referred to as SITE). Mr. Jason A. Simpson and Ms. Mary Beth

Frank, experienced asbestos and lead paint inspectors representing IA performed the assessment and sample collection on July 18 and July 23, 2024.

DESCRIPTION OF ASSESSMENT

The purpose of this assessment is to aid Waco in the identification of hazardous materials requiring abatement prior to the proposed demolition of the Site. For the purposes of this assessment, “Hazardous Materials” includes asbestos containing materials (ACMs), Lead-

Based Paint (LBP), above ground heating oil tanks, polychlorinated biphenyl (PCB) containing light ballasts, battery operated lighting, and mercury containing fluorescent light tubes and thermostats. Accessible locations of the building’s interior and exterior, excluding roofing materials, were inspected. Appendix A contains the Chain of Custody forms, and the Laboratory Sample Data Sheets for all PLM bulk samples collected.

Appendix B and C contains Lead-Based Paint XRF results and Certifications respectively.

BUILDING DESCRIPTION

The Site consist of a two-story single-family house with an unfished basement and CMU block foundation. Interior finishes include wall and ceiling drywall and plaster, wood, ceramic and linoleum flooring, acoustical ceiling tiles, vinyl cove base in kitchen and ceiling texture overtop drywall.

410-544-6000

2 44 McPherson Road - Annapolis, MD 21401 - Phone: 410-320-2225

The plumbing and heating pipe were either uninsulated or insulated with foil wrapped in fiberglass insulation.

The house has white painted cement board siding and painted wood trim. The windows on the 1st and 2nd floor contain vinyl frames. The basement windows contain metal and wood frames. The roof is covered with black asphalt roof shingles overtop tar paper. The interior and exterior of the house are painted with a variation of latex and oil-based paints.

ASSESSMENT

Asbestos

As authorized, IA conducted asbestos inspections and collected bulk samples from suspect asbestos-containing materials (ACMs) to conform with Federal regulations requiring an asbestos inspection of a building prior to renovation or demolition, and State of Maryland

(MD) regulations requiring an asbestos inspection prior to issuance of a renovation or demolition permit. The MD regulations pertain to retail, commercial and industrial facilities built before 1986.

The assessment was limited to collecting representative bulk samples of accessible presumed asbestos containing materials (PACMs) identified within the interior and exterior of the Site. The assessment was performed following inspection and sampling guidelines established by the United States Environmental Protection Agency (EPA) Asbestos

Hazardous Emergency Response Act (AHERA); as well as the EPA National Emission

Standards for Hazardous Air Pollutants (NESHAP) regulation for asbestos and in general accordance with ASTM E 2356-18 Standard Practice for Comprehensive Building

Asbestos Surveys.

The inspector identified Homogenous Areas (HA) of suspect ACMs (an area of building material which is visually similar and contiguous) per construction phase in each structure, classified and assessed each suspect ACM, and presumed or sampled each homogenous area of suspect ACM per the referenced guidelines.

410-544-6000

3 44 McPherson Road - Annapolis, MD 21401 - Phone: 410-320-2225

IA staff inspected the interior and exterior of the Site for suspect ACMs including thermal system insulation (TSI), surfacing materials (e.g., ceiling and wall textures), and miscellaneous materials (e.g., vinyl floor tiles and mastics). When suspect materials were identified, IA staff collected representative bulk samples from each HA using modified

AHERA sampling protocols. The following suspect materials were sampled:

Drywall and Joint Compound

Wall and Ceiling Plaster

Acoustical Ceiling Tile

Floor Linoleum and Mastic

Ceramic Floor Tile

Vinyl Cove Base and Mastic

Ceramic Tile Grout

Ceiling Texture

Black Wall Mastic in Bathroom

Exterior Cement Board Siding

Exterior Door and Window Caulk

Roofing

IA recorded the areas of the building inspected, as well as areas where materials suspected of containing asbestos were located. During the asbestos survey a total of forty-three (43) bulk samples were collected for PLM analysis. The PLM bulk samples were then submitted to Environmental Hazard Services LLC (EHS) for asbestos analysis using United States

Environmental Protection Agency (EPA) Method EPA600/R-93/116. EHS is American

Industrial Hygiene Association and NVLAP accredited laboratories.

Each sample was individually numbered, and sample identification information was entered onto field data sheets. Bulk samples were collected in such a manner as to minimize the potential for fiber release. Building materials that contain asbestos fibers in amounts greater than one percent (1%) are ACMs and are regulated by the Occupational

Safety and Health Administration (OSHA), EPA, and MD. OSHA regulates building materials containing any percent including “trace” levels of asbestos.

APPLICABLE ASBESTOS REGULATIONS AND GUIDELINES

Renovation and Demolition EPA/NESHAP Guidelines

The EPA/National Emissions Standards for Hazardous Air Pollutants (NESHAP) regulations for asbestos apply to certain demolition and renovation projects in facilities containing ACM and/or assumed ACM.

410-544-6000

6 44 McPherson Road - Annapolis, MD 21401 - Phone: 410-320-2225

The NESHAP, 40 Code of Federal Regulations (CFR) 61, Subparts A and M, rule usually requires that all friable ACM and some categories of non-friable ACM be removed before a building is demolished.

This may require localized removal before or as part of a renovation. For renovation projects where friable ACM will be disturbed, the NESHAP rule may require appropriate work practices or procedures for the control of emissions. The following EPA/NESHAP definitions of ACM are very important in interpreting which NESHAP requirements may apply to the building.

Category I - Friable asbestos-containing material: any material containing more than 1% asbestos that when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

Category I - Non-friable asbestos containing material: asbestos containing packings, gaskets, resilient floor covering, and asphalt roofing products containing more than 1% asbestos that, when dry, cannot be crumbled, pulverized or reduced to powder by hand pressure.

Category II non-friable asbestos containing material: any material excluding

Category I non-friable ACM, containing more than 1% asbestos that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure. .

Regulated asbestos containing material (RACM): (1) friable ACM, (2) Category I non-friable ACM that has become friable (3) Category I non-friable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading, or (4) 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 materials in the course of demolition or renovation operations regulated by

NESHAP

Employee Exposure OSHA Standards

OSHA Standard 29 CFR 1910.1001 and 1926.1101 regulates employee exposure to asbestos. The OSHA asbestos standards for general industry and for construction mandate a Permissible Exposure Limit (PEL) of 0.1 fibers (equal to or longer than five (5) micrometers) per cubic centimeter of air (fiber/cc) determined as an eight (8) hour, Time-

Weighted Average (TWA) and an excursion limit of one (1) fiber/cc as a thirty (30)-Minute

TWA.

Also, for asbestos removal or renovation involving ACM, the Asbestos Construction

Standard (29 CFR 1926.1101) requires that specific procedures be followed, including enclosure of the work area, to control asbestos exposure of the building occupants ad well as employees involved in abatement or renovation activities. If ACM is managed in place, the OSHA Asbestos Construction Standard applies to employees who may contact or disturb ACMs during their work shift.

The following are selected OSHA definitions regarding asbestos work:

Class I asbestos work means activities involving the removal of TSI and surfacing

ACM and assumed ACM.

Class II asbestos work means activities involving the removal of ACM which is not thermal system insulation or surfacing material. This includes, but is not limited to, the removal of asbestos-containing wallboard, floor tile and sheeting, roofing and siding shingles, and construction mastics.

Class III asbestos work means repair and maintenance operations, where “ACM”, including TSI and surfacing ACM and assumed ACM, is likely to be disturbed.

Class VI asbestos work means maintenance and custodial activities during which employees contact but do not disturb ACM or assumed ACM and activities to clean up dust, debris and waste resulting in Class I, II and III activities.

Lead Paint Inspection

International Academy, Inc. (IA) completed a visual survey and lead inspection using a portable X-Ray Florescence (XRF) lead analyzer on assessable interior and exterior paint that could be impacted during the demolition activities. Mr. Sean Gaglione, an experienced

State of Maryland lead paint inspector (MD Cert#15040) conducted the inspection, testing and quality review. The Site work was performed on July 23, 2024.

Survey Methods

IA used a Thermo Scientific Niton XLp, portable X Ray Fluorescence (XRF), lead-in-paint analyzer, model # 300A, serial #96510, to test painted surfaces that are suspected of containing lead. Measurements were made in accordance with the United States

Department of Housing and Urban Development (HUD); Guidelines for the Evaluation and control of Lead-Based Paint Hazards in Housing, June 2012, Second Edition.

The inspection protocol was based upon our approved company inspection protocol and the Department of Housing and Urban Development (HUD) Guidelines for the Evaluation and Control of Lead-Based Paint in Housing, 2012 revision, single-family housing protocol. The HUD Guidelines are considered the state of the art for lead-based paint testing. The HUD Guidelines require specific surfaces to be tested and require specific quality control methods.

HUD requires performing one test on every testing combination (defined to be a unique combination of component, substrate, and room equivalent) and each wall in each room equivalent. Additionally, the Guidelines recommend grouping testing combination systems with likely similar painting histories, such as door frames, jambs, and casings or windowsills, casings, and aprons, together for classification purposes. Note that the definition of LBP includes “any paint, varnish, shellac, or other coating.” Therefore, testing included stained or glazed components (such as ceramic tile or porcelain fixtures) which might not appear to be painted.

Depending upon the precision achieved during each test, the combination is classified as

LBP, high-inconclusive, low-inconclusive, lead-containing, or none detected.

410-544-6000

9 44 McPherson Road - Annapolis, MD 21401 - Phone: 410-320-2225

LBP is defined to be paint containing equal to or greater than 0.7 (mg/cm2) via XRF or

0.5% lead by weight via paint chip sample analysis.

Lead-containing paint is defined to be paint containing detectable amounts of lead less than the definition of LBP. Results which are too close to the definition of LBP for the instrument to classify are termed inconclusive. Inconclusive ranges are defined by the XRF

Performance Characteristics Sheet (PCS), developed by the EPA for this instrument and every other type of XRF. The PCS inconclusive range for this instrument, depending upon the precision achieved is 0.6 - 1.1 mg/cm2. The mid-point of the inconclusive range separates high and low inconclusive ranges.

The XRF was subjected to manufacturer-recommended quality control standardization at the beginning of the inspection. Quality control standardization reported values within the recommended range. Additionally, the XRF was subjected to HUD-required calibration validation at the beginning of the inspection and at the conclusion of the inspection. Each calibration validation included three tests on National Institute of Standards and

Technology (NIST) standard reference material (SRM) 2573. The average of each set of three quality control tests conformed to the thresholds listed in the PCS, validating the XRF calibration.

Lead-Based Paint (LBP) equal to or greater than 0.7 (mg/cm2) was identified several interior and exterior building components. Appendix B contains a summary of surfaces tested and the respective lead concentrations. Paint containing 0.7 (mg/cm2) of lead or greater is yellow highlighted and reported as “Positive” on the XRF Results Table.

Above Ground Heating Oil Tanks

The IA representative inspected the Site for above ground heating oil tanks. IA representative observed one (1) 275gallon heating oil tank in the basement of the house.

The volume of oil within the tank is unknow.

10 44 McPherson Road - Annapolis, MD 21401 - Phone: 410-320-2225

Mercury Components

IA inspected the house for fluorescent light lamps and wall mounted thermostats.

These fixtures often contain a small amount of mercury that is regulated under the EPA’s

Resource Conservation and Recovery Act (RCRA) program. IA did not observe any fluorescent light lamps or mercury containing thermostats.

Light Ballasts and Batteries

IA inspected the house for electric light ballasts. Older light ballast often contains regulated polychlorinated biphenyl (PCB) oil that requires proper handling and disposal. IA did not observe any light ballasts in the interior and exterior of the house.

IA inspected the house for emergency lighting and exit signs. Emergency lighting and exit signs contain batteries. Batteries are classified as hazardous waste and must be properly disposed of in accordance with EPA RCRA regulation. The batteries can be recycled by certain permitted facilities to provide a more beneficial option for disposal. IA did not observe emergency lighting or exit sign fixtures and/or batteries at the Site.

CONCLUSION AND RECOMMENDATIONS

Asbestos

In accordance with Title 40 of the Code of Federal Regulation (CRF) Part 61, Subpart M the NESHAP and MD Department of the Environment, the identified Category I and II

Non-Friable ACMs must be removed if renovation/demolition activities will impact the

ACM or disturb the matrix of the ACM. The abatement activities must be performed by a

MD licensed asbestos abatement contractor and EPA accredited persons in strict compliance with EPA, OSHA, and MD regulations. The following Category I and II Non-

Friable ACM were identified at the SITE:

410-544-6000

11 44 McPherson Road - Annapolis, MD 21401 - Phone: 410-320-2225

1. 4% Chrysotile asbestos was identified in the green ceramic wall and floor tile black adhesive in 2nd floor bathroom. The ACM black mastic is classified as a

Category I Non-Friable ACM. The mastic is reported to be in good condition and was observed beneath the green ceramic tile adhered to the floors and walls (See

Photo Below).

2. 15% Chrysotile asbestos was identified in the linoleum sheet flooring throughout the kitchen. 2% Chrysotile asbestos was identified in the associated yellow adhesive. The ACM linoleum and associated mastic is reported to be intact and in good condition (See Photo Below).

Niton XLp 300, 9/24/2004, ed. 1

Performance Characteristic Sheet

EFFECTIVE DATE: September 24, 2004 EDITION NO.: 1

MANUFACTURER AND MODEL:

Make: Niton LLC Tested Model: XLp 300 Source: 109Cd Note: This PCS is also applicable to the equivalent model variations indicated below, for the Lead-in-Paint K+L variable reading time mode, in the XLi and XLp series:

XLi 300A, XLi 301A, XLi 302A and XLi 303A.

XLp 300A, XLp 301A, XLp 302A and XLp 303A.

XLi 700A, XLi 701A, XLi 702A and XLi 703A.

XLp 700A, XLp 701A, XLp 702A, and XLp 703A.

Note: The XLi and XLp versions refer to the shape of the handle part of the instrument. The differences in the model numbers reflect other modes available, in addition to Lead-in- Paint modes. The manufacturer states that specifications for these instruments are identical for the source, detector, and detector electronics relative to the Lead-in-Paint mode.

FIELD OPERATION GUIDANCE

OPERATING PARAMETERS:

Lead-in-Paint K+L variable reading time mode.

XRF CALIBRATION CHECK LIMITS:

0.8 to 1.2 mg/cm2 (inclusive)

The calibration of the XRF instrument should be checked using the paint film nearest 1.0 mg/cm2 in the NIST Standard Reference Material (SRM) used (e.g., for NIST SRM 2579, use the 1.02 mg/cm2 film).

If readings are outside the acceptable calibration check range, follow the manufacturer's instructions to bring the instruments into control before XRF testing proceeds.

SUBSTRATE CORRECTION:

For XRF results using Lead-in-Paint K+L variable reading time mode, substrate correction is not needed for:

Brick, Concrete, Drywall, Metal, Plaster, and Wood

BACKGROUND INFORMATION

EVALUATION DATA SOURCE AND DATE:

This sheet is supplemental information to be used in conjunction with Chapter 7 of the HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing ("HUD Guidelines"). Performance parameters shown on this sheet are calculated from the EPA/HUD evaluation using archived building components. Testing was conducted in August 2004 on 133 testing combinations. The instruments that were used to perform the testing had new sources; one instrument’s was installed in November 2003 with 40 mCi initial strength, and the other’s was installed June 2004 with 40 mCi initial strength.

OPERATING PARAMETERS:

Performance parameters shown in this sheet are applicable only when properly operating the instrument using the manufacturer's instructions and procedures described in Chapter 7 of the HUD Guidelines.

SUBSTRATE CORRECTION VALUE COMPUTATION:

Substrate correction is not needed for brick, concrete, drywall, metal, plaster or wood when using Lead-in- Paint K+L variable reading time mode, the normal operating mode for these instruments. If substrate correction is desired, refer to Chapter 7 of the HUD Guidelines for guidance on correcting XRF results for substrate bias.

EVALUATING THE QUALITY OF XRF TESTING:

Randomly select ten testing combinations for retesting from each house or from two randomly selected units in multifamily housing. Use the K+L variable time mode readings.

Conduct XRF retesting at the ten testing combinations selected for retesting.

Determine if the XRF testing in the units or house passed or failed the test by applying the steps below.

Compute the Retest Tolerance Limit by the following steps:

Determine XRF results for the original and retest XRF readings. Do not correct the original or retest results for substrate bias. In single-family housing a result is defined as the average of three readings. In multifamily housing, a result is a single reading.

Therefore, there will be ten original and ten retest XRF results for each house or for the two selected units.

Calculate the average of the original XRF result and retest XRF result for each testing combination.

Square the average for each testing combination.

Add the ten squared averages together. Call this quantity C.

Multiply the number C by 0.0072. Call this quantity D.

Add the number 0.032 to D. Call this quantity E.

Take the square root of E. Call this quantity F.

Multiply F by 1.645. The result is the Retest Tolerance Limit.

Compute the average of all ten original XRF results.

Compute the average of all ten re-test XRF results.

Find the absolute difference of the two averages.

If the difference is less than the Retest Tolerance Limit, the inspection has passed the retest. If the difference of the overall averages equals or exceeds the Retest Tolerance Limit, this procedure should be repeated with ten new testing combinations. If the difference of the overall averages is equal to or greater than the Retest Tolerance Limit a second time, then the inspection should be considered deficient.

Use of this procedure is estimated to produce a spurious result approximately 1% of the time. That is, results of this procedure will call for further examination when no examination is warranted in approximately 1 out of 100 dwelling units tested.

TESTING TIMES:

For the Lead-in-Paint K+L variable reading time mode, the instrument continues to read until it is moved away from the testing surface, terminated by the user, or the instrument software indicates the reading is complete. The following table provides testing time information for this testing mode. The times have been adjusted for source decay, normalized to the initial source strengths as noted above. Source strength and type of substrate will affect actual testing times. At the time of testing, the instruments had source strengths of 26.6 and 36.6 mCi.

CLASSIFICATION RESULTS:

XRF results are classified as positive if they are greater than or equal to the threshold, and negative if they are less than the threshold.

DOCUMENTATION:

A document titled Methodology for XRF Performance Characteristic Sheets provides an explanation of the statistical methodology used to construct the data in the sheets, and provides empirical results from using the recommended inconclusive ranges or thresholds for specific XRF instruments. For a copy of this document call the National Lead Information Center Clearinghouse at 1-800-424-LEAD.
