Re: Pre-Renovation Asbestos Inspection, Nashua City Hall

Motor Vehicles Dept., Tax Offices, Assessing Dept., & City Clerk

TLG Job Number 20-18266

Prepared By: Stephen McPherson

Report Date: August n, 2020

The

LAWSON

GROUP

Thinking. Without the Box.

Introduction:

On July 28, 2020, Stephen McPherson, Senior Safety & Health Professional with The Lawson Group (TLG), performed a Limited Pre-Renovation Survey for Asbestos Containing Building Materials (ACM/ACBM) and Lead Based Paint (LBP). The Survey was performed at City of Nashua, Nashua City Hall in the following Departments:

• Motor Vehicle & Tax Office

• Assessing

• City Clerk

The laboratory results for the bulk Asbestos samples are included in Appendix Al, and All. Paint Sample laboratory results are in Appendix B.

Discussion:

Asbestos Survey:

The survey was conducted to document the presence of ACM in Ceiling Tiles that may be impacted during scheduled renovations/demolition of the building. Based on the analytical results for the bulk samples collected and our visual observations, ACM was identified in some of the building materials sampled in the Motor Vehicle, Tax Office, and the Assessing Departments. ACM was not identified in the City Clerk Area.

During the survey, 48 samples were collected following guidelines in the Asbestos Hazard Emergency Response Act (AHERA), however, the survey was performed to comply with the Environmental Protection Agency (EPA), National Emission Standards for Hazardous Air Pollutants (NESHAP), and State of New Hampshire Department of Environmental Services (NH DES) Env-A 1804.01 regulations, which require a thorough inspection for ACBM be conducted prior to any demolition/renovation of a facility.

Samples were delivered to a National Voluntary Laboratory Accreditation Program (NVLAP)-accredited laboratory for the analysis of bulk Asbestos samples by PLM. According to Federal and State regulations, materials containing greater than one percent (> 1%) Asbestos by dry weight are Asbestos containing.

The survey was performed at select departments in Nashua City Hall in Nashua NH; TLG performed only limited exploratory demolition in representative locations to identify areas where hidden ACM may be present. Since not all these types of locations could be accessed, additional ACM may be present in these areas, and care should be utilized when opening wall or ceiling chases.

City Clerk Area

Non-Asbestos Materials:

Asbestos was not detected in the following materials that were sampled and analyzed during the survey.

Material General Location

Pipe and Fitting Insulation

Ceiling Tiles Throughout

Cove base and adhesive

Gypsum Wall Board/Joint Compound

The survey was performed from the interior of the building which would be impacted by scheduled renovation of the City Hall Department. TLG did not disassemble mechanical, plumbing, or electrical components or perform inspections of all wall cavities or below grade. If a suspect material not identified and sampled as part of this survey is found, it should be assumed to be Asbestos containing until further sampling and analysis can be performed and will have to be removed in accordance with State and Federal Asbestos Regulations prior to renovation of the structure.

ACM must be abated in accordance with the State of New Hampshire and Federal requirements prior to activities such as renovation or demolition, which may directly disturb these materials.
