I. LEAD-BASED PAINT INSPECTION SUMMARY

Inspection for: Minneapolis VA Medical Center

Performed at: Minneapolis VA Medical Campus – Building 223

Performed by: Matt Lindberg, Institute for Environmental Assessment

Inspection Date: November 1, 2007

Instrument Used Thermo Fisher Scientific Niton X-Ray Fluorescent (XRF) Analyzer.

XRF Serial Number: 16071

Lead-Based Paint Standard: 1.0 mg/cm2 with Niton XRF analysis.

The inspection was conducted in accordance with the U.S. Department of Housing and Urban Development (HUD) Guidelines for the Evaluation and Control of Lead-Based Paint in Housing. All accessible painted surfaces within the interior and exterior of the building(s) were inspected. Surfaces were analyzed for lead content utilizing the XRF Analyzer. All samples were given a result of positive or negative for lead (above or below 1.0 mg/cm2), the standard established by the Minnesota Department of Health (MDH) and HUD for lead in paint. Results are located in Appendix A.

For purposes of renovation, the renovation contractor must be notified of the lead content in paint. It is the contractor’s responsibility to comply with OSHA’s Lead in Construction “Interim Final Rule” 29 CFR 1926.62. OSHA does not acknowledge the standards established by MDH and HUD and regulates any amount of lead in paint.

The Minnesota Pollution Control Agency (MPCA) requires that all loose and flaking lead-based paint (>1.0 mg/cm2) to be stabilized prior to demolition. Paint on all tested building materials was rated as being intact, fair or poor.

Calibration check tests were conducted before, after and every four hour work shift during the inspection. These checks were performed on thin films supplied by the XRF manufacturer with known concentrations of lead. These checks are labeled on the XRF report as “Calibrate”.

II. CONSTRUCTION HISTORY AND SITE DESCRIPTION

Minneapolis VA Medical Campus – Building 223

Basic Summary of Building Construction:

The original building was constructed prior to the enactment of the Lead-Based Paint Poisoning Prevention Act of 1978, and therefore all painted surfaces within the interior of the building and exterior of the building were suspect for lead-based paint.

The intent of this inspection was to complete a lead-based paint inspection of all paint surfaces and a visual inspection to determine lead-based paint hazards. Only immediately accessible areas were evaluated, excluding wall cavities, attics, air plenums and roofing systems. Materials not identified in this report should be assumed to contain lead or sampled prior to disturbance. No soil or lead dust samples were collected as part of this assessment.

Site Description:

Building 223 is a two (2) level structure including a basement, originally constructed in 1935. The building was unoccupied at the time of the inspection and is used for storage, warehouse and training facility. The construction of the building is wood and concrete frame with a wood exterior siding. The interior of the building has plaster, wood, concrete and drywall walls and ceilings.

III. LEAD-BASED PAINT SAMPLING SUMMARY

On November 1, 2007, a lead-based paint inspection was conducted by Matt Lindberg of the Institute for Environmental Assessment. The objective of the Lead-Based Paint Inspection was to test all structural painted surfaces. In addition, the visual assessment performed only describes the condition of the areas evaluated on the date of the inspection. The condition of a painted surface can change quickly.

IEA used the lead-based paint protocol described in the U.S. Department of Housing and Urban Development (HUD) “Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing” (Revised October 1997, Chapter 7). Paint containing greater than or equal to 1.0 milligram of lead per square centimeter (≥1 mg/cm²) when measured by X-Ray Fluorescence (XRF) is considered lead-based paint (LBP) as specified by HUD and the Environmental Protection Agency (EPA).

Specific building components determined to have lead concentrations equal to or greater than 1.0 mg/cm² are listed in Table 1.

IV. VISUAL EXAMINATION

The initial building walk-through was conducted throughout the interior and exterior of the building to check for general condition.

Paint condition was assessed by classifying surfaces into intact, fair and poor categories.

Discussion of Findings:

All areas were rated as intact, fair or poor. An “intact” surface is defined here as one where there is no visible damage and the entire painted surface is intact. A “fair” surface is defined here as one where the paint is showing moderate damage, whereas a “poor” surface is showing significant deterioration. It is important to note that intact areas are not included in the table 2 below, but all fair or poor painted substrates are.

V. DISCUSSION AND RECOMENDATIONS OF XRF RESULTS

According to Minnesota state standards, a lead hazard is a painted surface identified as containing lead-based paint and is either showing deterioration or is considered an impact or friction surface. Below are recommendations for action based on the painted areas which were identified as hazardous through the visual examination. It is recommended that ongoing monitoring take place to re-evaluate any existing and potential lead-based hazards. See Appendix B for sample results and locations.

Window and Window Components Metal windows at the exterior building side B and D were listed in poor condition. When sampled with an XRF, these windows and their components tested positive for lead-based paint. The use of lead-safe work practices to return the painted surfaces to an intact condition is recommended. The damaged surfaces can be addressed by encapsulation, paint stabilization, paint removal, component removal or enclosure.

Door and Door Components Lead-based paint is located on doors and door components throughout the interior and exterior of the building. The paint on the door and door components was listed in fair/poor condition. Painted surfaces listed in fair condition are not considered a lead-based paint hazard. However, it is recommended that there conditions be monitored. It is recommended that painted surfaces in poor condition have the paint returned to an intact condition utilizing lead-safe work practices. The damaged surfaces can be addressed by encapsulation, paint stabilization, paint removal or component removal.

Garage Doors and Garage Door Casing Lead-based paint is located on garage doors and garage door casings throughout the interior and exterior of the building. The paint on the garage doors and garage door casings was listed to be in fair/poor condition. Painted surfaces listed in fair condition are not considered a lead-based paint hazard.

However, it is recommended that there conditions be monitored. It is recommended that painted surfaces in poor condition have the paint returned to an intact condition utilizing lead-safe work practices. The damaged surfaces can be addressed by encapsulation, paint stabilization, paint removal or component removal.

Walls and Ceilings and Columns Lead-based paint is located on walls, ceilings and columns throughout the interior of the building. The paint on the walls, ceiling and columns was listed in fair/poor condition. Painted surfaces listed in fair condition are not considered a lead-based paint hazard. However, it is recommended that there conditions be monitored. It is recommended that painted surfaces in poor condition have the paint returned to an intact condition utilizing lead-safe work practices. The damaged surfaces can be addressed by encapsulation, paint removal or paint stabilization.

Ceiling Beams and Structural Components Lead-based paint is located on the ceiling beams and structural components throughout the interior of the building. The paint on the ceiling beams and structural components was listed in fair/poor condition.

Painted surfaces listed in fair condition are not considered a lead-based paint hazard. However, it is recommended that there conditions be monitored. It is recommended that painted surfaces in poor condition have the paint returned to an intact condition utilizing lead-safe work practices. The damaged surfaces can be addressed by encapsulation, paint stabilization or paint removal.

Stair Railing Lead-based paint is located on the stair railing in the stairwell to the basement. The paint associated with the stair railing was listed in poor condition. It is recommended that painted surfaces in poor condition have the paint returned to an intact condition utilizing lead-safe work practices. The damaged surfaces can be addressed by encapsulation, paint stabilization, paint removal or component removal.

Roofing System The exterior painted roofing systems were inaccessible for sampling. The painted surfaces associated with the roofing system should be assumed to be lead-based paint throughout the entire exterior building or sampled prior to disturbance. The roofing system was observed to be in poor condition and is flaking and deteriorating. It is recommended that these surfaces be returned to intact condition utilizing lead-safe work practices. The damaged surfaces can be addressed by encapsulation, paint stabilization or paint removal.
