S02 St Cloud VA West Side Tunnels- Lead Paint Testing Report.pdf

CLIENT: Anderson Engineering of Minnesota, L.L.C. PROJECT NUMBER: 21175.12

DATE OF SAMPLING: 12/22/2023 DATE OF REPORT: 1/5/2024

PROJECT: Lead Paint Testing at the St. Cloud VA Health Care System – West Main Steam Line Project

Landmark Environmental LLC (Landmark) was retained by Anderson Engineering of Minnesota, L.L.C.

(the Client) to perform lead-based paint testing (Testing) as part of a project at the St. Cloud Veterans

Affairs (VA) Health Care System (VAHCS) located in St. Cloud, Minnesota (the Property). The Testing was conducted in the western portion of the tunnel system as part of the Replace/Add Steam Mains West

Side Campus – St. Cloud VAHCS project (the Project). Tunnels and crawlspaces between manhole 21 and Building 51 were included in the Testing. In the crawlspaces of the buildings, approximately 20 feet on either side of the main steam lines were included in the Testing. A diagram of the locations included in the Testing has been included in this report.

Landmark conducted the Testing on December 22, 2023. All test results are included in the attached sheets. Results that exceeded the OSHA Standards have been transferred to the following table:

INTERPRETING PAINT SAMPLING RESULTS

Minnesota Occupational Safety and Health Administration (MNOSHA) has adopted the federal

Occupational Safety and Health Administration (OSHA) standards and operates an OSHA approved state plan. This Testing does not meet the Department of Housing and Urban Development (HUD) or

Minnesota Department of Health (MDH) definition of a lead paint inspection.

Testing surfaces for lead and establishing "safe" levels of lead content is difficult. The OSHA standard does not identify a lower level of lead content in paint that will eliminate the initial air monitoring requirement. Landmark tested a total of fifteen (15) painted surfaces for lead. Thirteen (13) of these surfaces tested above the Occupational Safety and Health Administration (OSHA) guideline of 0.0 milligrams per square centimeter (mg/cm2). Eleven (11) of these surfaces also tested above the

Minnesota Department of Health (MDH)/Environmental Protection Agency (EPA)/ and the Housing and urban Development (HUD) lead paint level of 1.0 mg/cm2. Two (2) surfaces tested at this OSHA guideline. Additionally, 2 quality control tests were performed during the Testing, and 2 tests were found to be inconclusive (Null). When a Null reading was given, a retest was performed immediately after with a result obtained. If these results are used by a contractor to comply with the OSHA interim lead in construction standard (29 CFR 1926.62), the contractor must evaluate the potential for lead dust or fume generation from all activities which will disturb paint containing any detectable quantity of lead.

OSHA Standards apply to any employee disturbing (creating dust or fumes) materials covered with lead-based paint. OSHA regulates lead as an airborne contaminant. Airborne concentrations during disturbance will vary with both the concentration of lead paint and with the operation (manual demolition, sanding, etc.). OSHA requires the contractor to show proof that the operations disturbing lead-based paint in any concentration will not exceed the OSHA Action Level of 30 micrograms of lead per cubic meter of air (µg/m3) or the OSHA Permissible Exposure limit of 50 µg/m3.

This information is provided as a general approach to compliance with OSHA 29CFR 1926.62. It is not the intent of Landmark that this information applies to all situations involving the standard. The standard should be consulted in all cases, and interpretations verified with OSHA prior to construction.

Landmark is a Certified Lead Firm with the Minnesota Department of Health (License No. LF5321).

A NITON 706A X-Ray Fluorescence field portable analyzer (XRF) was used to conduct lead paint testing in the Project work area where paint was observed. The Performance Characteristic Sheet for this instrument is included in the Appendix. The following information details information on the specific

XRF used in this inspection.

XRF Manufacturer Niton

XRF Model Number XL706A

XRF Serial Number 89147

XRF Mode of Operation K + L + Spectra Mode

XRF Source Date 08/26/20

XRF Source Activity Cadmium 109

The XRF was set on the mode of operation “K+L+Spectra” during the inspection phase of the work. The equipment does not need substrate corrections for brick, concrete drywall, plaster, and wood. Calibration checks were conducted at the beginning, end, and every 4 hours of work.

Conditions

Landmark conducted the Testing and the Report in a manner consistent with the care and skill ordinarily exercised by members of the environmental profession in the community under similar budget and time constraints.
