SECTION 1.0

INTRODUCTION

An asbestos survey was performed at Baxter Water Treatment Plant located at 9001 State Road, in Philadelphia, Pennsylvania. The survey was conducted on December 12th, 2024, by Steve Woronicak, a City of Philadelphia Asbestos Investigator, from Batta Environmental Associates, Inc. (BEA).

The specific project scope will be limited to the Door and Window Replacement activities during the renovations at the Pre-Treatment Building and Intake Building at the Baxter Water Treatment Plant located at 9001 State Road in Philadelphia, Pennsylvania.

The inspection was performed by a City of Philadelphia Asbestos Investigator, experienced in identifying and sampling suspect ACM. If there was newly discovered material present that was not homogenous to the original samples, additional sampling would be required. All observed suspect materials were sampled to determine asbestos content and no materials were assumed to contain asbestos.

All samples collected were analyzed at Batta Laboratories, LLC, using Polarized Light Microscopy (PLM) methods.

METHODS AND LIMITATIONS

2.1 ASBESTOS SURVEY METHODS

The site was inspected for suspect ACM, unless otherwise noted. Each observed suspect material was assigned a homogenous area number, described, and measured. Each observed suspect material was sampled or assumed to be asbestos. Samples of suspect ACM were collected using procedures established by the United States (US) Environmental Protection Agency (EPA) Code of Federal Regulations (CFR) Title 40 Part 763 Subpart E, Asbestos-Containing Materials in Schools.

At the beginning of the survey, the inspector(s) conducted a walkthrough of the areas identifying and sampling different types of probable ACM and categorizing these materials.

Each probable ACM was grouped into homogenous areas, which group a particular material by similar characteristics such as appearance, texture, manufacturer, etc. All similar materials within a particular building or process area were in their own homogenous area groups.

ACM’s were also further divided into three categories:

• “Surfacing Materials” material that is sprayed-on, troweled on, or otherwise applied to surfaces, such as acoustical plaster on ceilings and fireproofing materials on structural members, or other materials on surfaces for acoustical, fireproofing, or other purposes.

• “Thermal System Insulation” material applied to pipes, fittings, boilers, breeching, tanks, ducts, or other structural components to prevent heat loss or gain, or water condensation, or for other purposes.

▪ “Miscellaneous ACM“ interior building material on structural components, structural members or fixtures, such as floor and ceiling tiles, and does not include surfacing material or thermal insulation.

ACM’s inventoried in this survey are classified as either friable or non-friable. Friable ACM can be crumbled or reduced to powder by hand pressure whereas non-friable ACM cannot.

The EPA asbestos NESHAP regulation further classifies nonfriable ACM into two categories.

• Category I. Nonfriable ACM includes any asbestos-containing packing, gasket, resilient floor covering or asphalt roofing product.

• Category II. Nonfriable ACM includes any nonfriable ACM other than Category I nonfriable ACM.

Samples were collected in airtight, sealed bags for transportation to Batta Laboratories, LLC for analysis. During sample collection procedures, good safety and hygiene practices were implemented to prevent asbestos airborne contamination from being introduced into the building’s atmosphere.

All field records pertaining to samples collected during this inspection can be found in Appendix B of this report and each sample is listed as follows:

1. Field Number

2. Lab Number

3. AHERA Classification

4. Sample Location

5. Material Sampled

6. Lab Results

All lab data pertaining to the samples analyzed can be found in Appendix A of this report and each sample is listed as follows:

1. Date Analyzed

2. Field Sample Number

3. Lab Sample Number

4. Sample Location

5. Asbestos Content

6. Non-Asbestos Content

Samples were analyzed using an A, B, C… positive stop protocol for each set of homogenous materials (materials with similar characteristics). If a sample in the homogenous set tested positive for asbestos (greater than 1% by composition) then the other samples in that set were not analyzed. If asbestos was not detected in a sample, then all samples from that homogenous set were analyzed for asbestos until one tested positive.

2.2 LABORATORY ANALYSIS METHODS

All samples collected during the survey were analyzed at Batta Laboratories, LLC, an A.I.H.A., NVLAP certified laboratory. Upon arrival at the laboratory, the samples were logged-in and submitted for analysis.

PLM samples were analyzed utilizing the Environmental Protection Agency’s test method:

“Methods for the determination of Asbestos in Bulk Building Materials” (EPA 600/R-93/116, July 1993) and the McCrone Research Institute’s “The Asbestos Particle Atlas” as the principal analytical references. Additional treatment and tests may be required to accurately define composition (i.e. ashing, extraction, acetone treatment, and TEM).

The PLM method utilizes a light microscope equipped with polarizing filters. The identification of asbestos fiber bundles is determined by the visual properties displayed when the sample is treated with various dispersion staining liquids. Identification is substantiated by the actual structure of the fiber and the effect of polarized light on the fiber, all of which is viewed by a trained technician. The limit of detection of asbestos by PLM is about one percent (1%) by area.

Samples containing lower levels of asbestos are not reliably detectable by this technique.

Analysis was performed by using the bulk sample for visual observation and slide preparation(s) for microscopic examination and identification. The samples analyzed for asbestos (chrysotile, amosite, crocidolite, anthophyllite, and actinolite/tremolite), silicon carbide whiskers, carbon fibers, fibrous non-asbestos constituents (cellulose, synthetic, etc.), and non-fibrous constituents. 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.

The asbestos NESHAP recommends that asbestos bulk samples that are less than 10% by PLM are to be analyzed by point counting for friable ACM and mandates point counting when PLM results for friable ACM are in trace amounts (< 1%) in order to declare that the material is non-asbestos containing. The point-count procedure mandated by NESHAP is in the EPA “Interim” Bulk Method. For each layer to be point counted, eight mounts are made by dispersing 8 pinches of sample in suitable fluid. Each of the mounts is examined under the polarizing light microscope using an eyepiece reticule that superimposes a grid of points over the field of view. Fifty non-empty points are examined for each mount, yielding 400 points – some of which would be identified as asbestos and the rest as non-asbestos material.

2.3 LIMITATIONS

This survey was limited in scope to an asbestos survey of Baxter Water Treatment Plant at 9001 State Road, in Philadelphia, Pennsylvania, as defined by contract documents and the project scope of work. Hazardous materials such as lead based paint, PCBs, fluorescent light tubes, mercury switches, HID lamps, lead acid batteries, refrigerants, stored chemicals, or other environmentally sensitive materials were not assessed as part of this inspection.

This asbestos survey report has been prepared by BEA in a manner consistent with that level of care and skill ordinarily exercised by members of the profession currently practicing under similar conditions. No other warranty expressed or implied is made. The intent of this survey report is to assist the building owner or management in locating hazardous materials. This document is not intended to be utilized as a proposal or a project design document for the remediation of hazardous materials discovered during this investigation.

The survey was conducted to identify asbestos containing materials on the select interior areas of the building. Some asbestos containing materials may not have been discovered due to inaccessibility. Any suspect materials discovered subsequent to the issue of this survey report should be evaluated or sampled and analyzed to determine the nature of the suspect asbestos material.

BEA'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. The results, conclusions, and recommendations contained in this report pertain to conditions observed at the time of the survey.

SECTION 4.0

RECOMMENDATIONS

4.1 RECOMMENDATIONS FOR REGULATED ACM (RACM)

The following materials were NOT identified as RACM during this inspection:

These materials must be removed prior to any activity that would release asbestos fibers from this material. Specifically, any renovation or demolition activity that will crush, abrade, or dissolve the matrix of this material must be performed by a Pennsylvania licensed Asbestos Contractor. If these materials are in good condition and not impacted by the renovation/demolition and will remain on/in the facility, no other special handling, or action is required for these materials.

4.2 RECOMMENDATIONS FOR CATEGORY I NONFRIABLE ACM

The following materials were NOT identified to be Category I Non-friable ACM during this inspection:

These materials are required to be removed by a Pennsylvania licensed asbestos contractor if proposed renovations or demolition will impact these materials in such a manner as to render them friable and thus RACM. Specifically, any renovation or demolition activity that will crush, abrade, or dissolve the matrix of these materials must be performed by a Pennsylvania-licensed Asbestos Contractor. If these materials are in good condition and not impacted by the renovation/demolition or if renovation/demolition work will not render the material friable then they may remain on/in the facility. If demolished, this material and the building components associated with it must be disposed of in a Construction/Demolition landfill and must not be reused or recycled.

4.3 RECOMMENDATIONS FOR CATEGORY II NONFRIABLE ACM

The following materials were identified as Category II Non-friable ACM during this inspection:

- Door Caulk, Window Caulk, and Building Caulk

These materials identified as Category II Nonfriable ACM must be removed prior to any renovation or demolition activity that will crush, abrade, or dissolve the matrix of this material.

The removal of this material must be performed by a Pennsylvania-licensed Asbestos Contractor.

If this material is in good condition and not impacted by the renovation/demolition and will remain on/in the facility, no other special handling, or action is required for this material.

4.4 GENERAL RECOMMENDATIONS

Based on the results of this survey, BEA has the following general recommendations:

• If any suspect materials are discovered after this inspection that were not assessed in this survey then they should be sampled and analyzed to determine asbestos content and to initiate appropriate responses.

The Pennsylvania Department of Environmental Protection and the US Environmental Protection Agency – Region III, require notification of intent to renovate or demolish when asbestos is present. Notification must be sent at least 10 working days prior to the start of any construction activities. The general contractor should also keep a copy of this survey at the construction site during the entire construction project as proof of compliance with 40 CFR 61 (NESHAP).
