About this file

This is a Limited Asbestos and Hazardous Materials Study prepared by H2M Architects, Engineers, Land Surveying and Landscape Architecture for the Incorporated Village of Hempstead, New York, dated July 9, 2025. The study was conducted at 335 Greenwich Street, Hempstead, New York (H2M Job No. HEMV2502) in accordance with a request from Deputy Mayor Jeff Daniels. The survey collected bulk samples for asbestos-containing materials (ACM), lead-based paint (LBP), and polychlorinated biphenyls (PCBs) in sealants from materials scheduled to be disturbed during an upcoming renovation project. Sampling was performed on June 13, 2025, by New York State Department of Labor certified inspectors Anthony Calabrese and Dakota A. Barnoski, with laboratory analysis conducted by EMSL Analytical of Carle Place, New York, which holds New York State Department of Health Environmental Laboratory Approval Program certification.

The asbestos testing results indicate that of the multiple bulk samples collected from various locations throughout the pool house facility—including interior and exterior CMU blocks, mortar, caulking materials, fiberglass pipe jackets, stone walls, and roof components—only one material tested positive for asbestos: tar at the roof parapet, with an approximate quantity of 50 linear feet of ACM. All other sampled materials, including window caulk, door caulk, utility area materials, pool perimeter caulk, rubber roof layers, and siding, tested as non-ACM or non-ACM with trace amounts. These findings align with the definitions established by the Asbestos Hazard Emergency Response Act (AHERA), the Occupational Safety and Health Administration (OSHA), and New York State Department of Labor regulations, which classify asbestos-containing material as any material containing greater than one percent (1%) of asbestos.

Re: Limited Hazardous Materials Survey

Incorporated Village of Hempstead 335 Greenwich Street, Hempstead, New York H2M Job No.: HEMV2502

Dear Deputy Mayor Daniels:

In accordance with your request, H2M architects + engineers (H2M) conducted a limited hazardous materials survey collecting samples for asbestos (ACM), lead based paint (LBP), and polychlorinated biphenyls (PCB) in sealants. We provide herein the results of our findings.

ASBESTOS SAMPLING

On June 13, 2025, H2M collected limited bulk samples of suspect asbestos containing materials (ACM) that were located at the above referenced property and are scheduled to be disturbed during the upcoming renovation project.

Bulk samples were submitted to EMSL Analytical, of Carle Place, New York. EMSL is certified by the New York State Department of Health (NYSDOH), Environmental Laboratory Approval Program (ELAP), No. 11480. Bulk samples were collected and submitted by New York State Department of Labor (NYS DOL), certified inspectors Mr. Anthony Calabrese (NYSDOL Cert. No. 24-6LTPL-SHAB) and Mr. Dakota A. Barnoski (NYSDOL Cert. No. 24-6TSV7-SHAB).

ASBESTOS RESULTS

According to the Asbestos Hazard Emergency Response Act (AHERA), the Occupational Safety and Health Administration (OSHA) and the NYSDOL (12 NYCRR Part 56); asbestos containing material (ACM) is defined as any material or product which contains greater than one percent (1%) of asbestos.

Please reference the table below for a summary of results.

Lead Based Paint Sampling On June 13, 2025, H2M collected paint chip samples of suspect lead-based paint from painted surfaces at 335 Greenwich Street, in Hempstead, New York. The sampling was performed by a US EPA Certified Lead Based Paint Risk Assessor, Mr. Kyle P Vander Schuyt (LBP-I-I173781-3)

Paint Chip samples were submitted to EMSL Analytical, Inc. (EMSL) of Carle Place, New York. EMSL is certified by the New York State Department of Health (NYSDOH), Environmental Laboratory Approval Program (ELAP), No. 11469 and EPA 7000B, AAS.

Lead Based Paint Results According to the U.S. Environmental Protection Agency (US EPA) lead based paint is defined as paint containing equal to or more than 0.5% lead by weight in paint chip samples.

EMSL maintains liability limited to cost of analysis. Interpretation and use of test results are the responsibility of the client. This report relates only to the samples reported above, and may not be reproduced, except in full, without written approval by EMSL. EMSL bears no responsibility for sample collection activities or analytical method limitations. The report reflects the samples as received. Results are generated from the field sampling data (sampling volumes and areas, locations, etc.) provided by the client on the Chain of Custody. Samples are within quality control criteria and met method specifications unless otherwise noted. Estimation of uncertainty available upon request.

This report is a summary of multiple methods of analysis, fully compliant reports are available upon request. All samples examined for the presence of vermiculite when analyzed via NYS 198.1. A combination of PLM and TEM analysis may be necessary to ensure consistently reliable detection of asbestos. Polarized-light microscopy is not consistently reliable in detecting asbestos in floor coverings and similar non-friable organically bound materials. This report must not be used to claim product endorsement by

NVLAP of any agency or the U.S. Government . Quantitative transmission electron microscopy is currently the only method that can be used to determine if this material can be considered or treated as non-asbestos containing. NOB= Non friable organically bound; N/A= Not applicable VCM= Vermiculite containing material.

Analysis following EMSL SOP for the Determination of Environmental Lead by FLAA. The laboratory has a reporting limit of 0.0064% by wt., based upon a minimum sample weight of

0.25g submitted to the lab, and is not responsible for any result or reporting limit provided in mg/cm2 since it is dependent upon an area value provided by non-lab personnel. A "<" (less than) result signifies that the analyte was not detected at or above the reporting limit. Measurement of uncertainty and definitions of modifications are available upon request.
