Gentlemen:

AERO EH&S, Inc. (AERO) is pleased to submit the attached Limited Asbestos & Lead Testing report for the referenced site. The testing included accessible locations specified by the Summer Consultants' Project Engineer during the walkthrough inspections as potentially impacted by the referenced project. The report includes the procedures and methods for testing.

As a result of our review and survey, lead-based paint and paint containing lead were identified. AERO has provided conclusions and recommendations regarding these materials within the report.

AERO appreciates the opportunity to perform limited asbestos and lead testing for Summer Consultants, Inc. Please contact our office if you have any questions.

Altmeyer Columns Full Repair Design

SSA Woodlawn Complex 6401 Security Boulevard

1.0 Purpose and Scope of Service

The purpose of this task was to identify and document the presence of asbestos-containing materials (ACM) and lead-containing paint on materials anticipated to be impacted by the Altmeyer Columns Full Repair Design project at the SSA Woodlawn Complex in Woodlawn, MD. The survey and review were conducted in accordance with the following scope of work.

Asbestos-Containing Materials

(1) Licensed asbestos inspectors conducted a visual inspection of representative materials suspected to contain asbestos that will be affected by the referenced project. The survey was conducted in general accordance with Occupational Safety and Health Administration (OSHA) and Environmental Protection Agency (EPA) AHERA requirements.

(2) Based on field observations, AERO prepared this report regarding the presence and extent of asbestos-containing materials potentially impacted by the project.

Lead-In-Paint

(1) An EPA Lead Paint Inspector trained in sampling protocols and use of the Viken Pb200i X-Ray Fluorescence Analyzer (XRF) conducted testing of representative painted surfaces that may be impacted by the planned activities.

(2) Use of the XRF instrument was in general accordance with the Performance Characteristic Sheet (PCS) methodology for the Heuresis Pb200i dated December 1, 2020. XRF instrument calibration checks were performed according to the PCS.

The PCS is provided as supplemental guidance to the US Housing and Urban Development (HUD) “Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing” and is a joint product of HUD and EPA.

(3) Testing locations were identified by substrate type, component, and color.

Surfaces to be tested only included painted building components that may be impacted by the project.

SSA Woodlawn Complex, Woodlawn, MD

(4) Based on field observations, existing data provided by the Client, and results of additional testing, AERO prepared this report regarding the presence and extent of lead-containing paints impacted by this project.

2.0 Findings

2.1 Asbestos-Containing Materials

The mechanical room in the basement of the Altmeyer Building, where this project is located, was completely abated of asbestos-containing materials. There were no suspect asbestos-containing materials anticipated to be impacted by the scope of this project observed during this survey.

2.2 Lead-in-Paint

AERO conducted a lead-based paint screening survey of representative surfaces and materials to identify lead-based paint that could be disturbed during the performance of work associated with the referenced project. The survey was performed by an EPA certified Lead Risk Assessor trained in sampling protocols and use of the Viken Pb200i X-Ray Fluorescence Analyzer (XRF).

The following building components identified during the inspection were suspected of being coated with paint containing lead and may be impacted by the referenced renovation project:

Metal Boiler Cladding Metal Boiler Housing

Metal Boiler Controls Metal Catwalk Handrails

Metal Catwalk Stair Stringers Metal Gas Piping

Metal Gas Valves Metal Gas Pressure Reducer

Concrete Boiler Base Concrete Floor

Concrete Equipment Pads Concrete Columns

Metal Safety Switch Metal Tank Stand

Metal Pump Motor Metal Pump Base

Metal Pump Support Metal Safety Guard

Metal Catwalk Columns Metal Catwalk Ladder

Metal Control Panel Enclosure Metal Pipe Stands

Metal Davit Arms Metal Shut Off

Metal Valves Metal Pressure Cut Offs

Metal “C” Channel Supports

SSA Woodlawn Complex, Woodlawn, MD

XRF testing revealed the following surfaces contained lead concentrations of 0.7 mg/cm2 or greater and are considered to be lead-based paint.

Metal Gas Valves Metal Catwalk Handrails

Metal Davit Arms Metal Safety Guard

XRF testing revealed lead concentrations less than 0.7 mg/cm2, but greater than the limit of detection for the instrument, on the following surfaces and are considered to be lead-containing:

Metal Boiler Cladding Metal Boiler Housing

Metal Boiler Controls Metal Gas Piping

Metal Catwalk Stair Stringers Metal Gas Pressure Reducer

Concrete Boiler Base Concrete Floor

Concrete Equipment Pads Concrete Columns

Metal Safety Switch Metal Tank Stand

Metal Pump Motor Metal Pump Base

Metal Pump Support Metal Catwalk Ladder

Metal Catwalk Columns Metal Pipe Stands

Metal Control Panel Enclosure Metal Shut Off

Metal Valves Metal Pressure Cut Offs

Metal “C” Channel Supports

XRF testing revealed no lead concentrations less than the limit of detection for the instrument used. All surfaces impacted by the scope of this project should be assumed to contain detectable concentrations of lead.

Appendix A contains a spreadsheet with all data obtained from the representative XRF testing, including lead concentrations reported in milligrams per square centimeter (mg/cm2) and a POS (positive) or NEG (negative) classification with respect to the threshold for lead-based paint for each reading. All POS values are indicated in red boldface in the spreadsheet. XRF reading location drawings depicting approximate reading locations are included in Appendix B.

State of Maryland regulations define a lead-based paint as any paint or other surface coating containing lead or lead in its compounds in any quantity greater than 0.50% lead by weight or more than 0.7 mg/cm2. Federal regulations define a lead-based paint as any paint or other surface coating containing lead or lead in its compounds in any quantity greater than 0.50% lead by weight, or more than 1.0 mg/cm2. The Occupational Safety and Health Administration (OSHA) regulates lead present in the work place in any concentration.

SSA Woodlawn Complex, Woodlawn, MD

The OSHA Standard requires an employer to ensure that no employee is exposed to lead at concentrations greater than 50 micrograms of lead per cubic meter of air (μg/M3) averaged over an eight-hour period. The Standard further requires the employer to make a determination of its employees' potential exposure to lead. The Standard details presumed exposure levels for various construction activities. The employer must provide adequate personal and respiratory protection to match the presumed exposure listed in the Standard. Deviation from the presumed exposure is typically achieved by performing personal monitoring during various representative construction activities. The level of personal and respiratory protection can then be modified based upon the results of the monitoring.

3.0 Conclusions and Recommendations

The following conclusions and recommendations are based upon the work conducted for this survey and AERO’s understanding of the project.

A. There were no suspect asbestos-containing materials anticipated to be impacted by the scope of this project identified during this survey.

B. If any suspected asbestos-containing materials are encountered during renovation activities, the materials should be assumed to be asbestos containing until sampling determines otherwise.

C. Lead-based and lead-containing paints were identified during the survey.

Removal of paint with lead as a result of demolition activities does not necessarily constitute a lead-based paint abatement provided they have not been included in the renovation plans to reduce or eliminate a lead hazard.

However, if lead-based paint is removed with the intention of reducing or eliminating a lead hazard, then the removal must be performed by a licensed lead abatement contractor.

D. Painted surfaces identified as being covered with paint containing lead in any concentration should be handled in accordance with the GSA Guide Specification Section 02090 “Lead Based Paint Control Procedures”, SSA OEHOS “Lead Compliance Program”, and 29 CFR 1926.62, the OSHA Lead Exposure in Construction Standard. Contractors should be notified of all known lead-containing paints prior to bidding on work at the Site.
