LEAD CONTAINING COATINGS SURVEY REPORT

1.0 INTRODUCTION

The USDA Forest Service of Missoula, Montana, contracted Mountain Consulting Services, LLC (Mountain Consulting) to provide a good-faith lead coatings survey for the 3-story; 39,000 ft²;

Historic Building 26 located on the Fort Missoula facility addressed at 322 Fort Missoula in Missoula, Montana.

This project was conducted to facilitate new occupancy phased renovations for the Building 26 structure. No prior survey documentation was provided for this project.

Mr. David A. Jones, EPA-Montana State Lead Risk Assessor; Certification Number: MT-R-14998- 3; Expiration: March 2, 2016 conducted the fieldwork portion of the survey on March 5th & 6th of 2014. (See Appendix A for inspector certifications).

The survey process uses a surface-by-surface measurement of suspected lead containing paint or ceramic tile glaze coatings by X-ray fluorescence (XRF). This survey complies with all applicable state and federal regulations and is provided to help the property owner determine the impact of lead coating and materials hazards for the scheduled phased renovation project.

2.0 X-RAY FLUORESCENCE TESTING

2.1 THEORY OF X-RAY FLUORESCENCE

Fluorescence can be defined as the emission (giving off) of electromagnetic waves by an atom when something excites it. An example of fluorescence is the visible light or glow given off by certain paints when a black light (a purple-looking ultraviolet light) is shone on them. This is the concept used in an X-ray lead-paint detector. The detector contains a source of radiation, a hermetically sealed radioactive isotope of cobalt (Co57) about the size of an aspirin tablet. The radiation is used to excite the atoms of a painted surface. As the surface returns to its normal state, it fluoresces.

The detector works something like a radio. Radio stations are assigned different frequencies, allowing the listener to select a single station. Lead fluoresces at a known frequency and, like a radio; the detector can be tuned to it. The fluorescence is sensed by the detector and displayed on a digital readout. The concentration of lead in the paint is expressed as mass (milligrams) per unit area (square centimeter).

2.2 XRF LEAD BASED PAINT SURVEY

Mountain Consulting collected Three-Hundred-&-Forty-Five (345) XRF assays and instrument calibration readings from the Fort Missoula Building 26 Structure, using the procedures outlined in the EPA’s Standard Operating Procedures for Measurement of Lead in Paint using X-Ray Fluorescence Spectrometer (EPA 600/8-91/214; 1991), the revised Chapter 7 (November 1997) of HUD’s Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing, and the Performance Characteristic Sheet for the Dynasil LPA-1.

Mountain Consulting used the “Dynasil, RMD, LPA-1” X-ray fluorescence (XRF) lead spectrum analyzer, Serial Number 3627 to perform nondestructive sampling of suspect lead coating’s or ceramic tile glazing’s.

Over time, the instrument’s radiation source “decays,” requiring longer times to reach standard precisions. Because of this, Mountain Consulting performs quality-control checks before, during, and after collecting data (depending on the length of the survey) to ensure that the LPA-1 is functioning properly and that assay results truly reflect lead levels at the sample points.

The instrument is calibrated using a standard from the National Institute of Standards and Technology backed by a common building material. Results of the averaged calibration readings are compared to the factory calibration results. Morning and periodic calibration readings are taken prior to survey start-up and at every 4 hour intervals during the XRF assay field testing portion of a survey.

Calibration results can be reviewed within the XRF assay report located in Appendix E.

An unlimited-test-length measurement was used to determine the lead concentration during the assays of each identified painted surface. The unlimited-length assay has an average precision (95% confidence) of about 0.2 mg/cm². The action level for this study was set at the standard of

1.0 mg/cm².

The RMD LPA-1 XRF software system produces a comprehensive report based on the assay data.

Each sample is a sequential number that identifies the room number, wall direction, component tested, substrate of the component, condition of the paint tested, substrate condition, and amount of lead detected in milligrams per square centimeter (mg/cm²).

2.3 BULK COATING SAMPLING

Destructive bulk paint and glazed ceramic tile sampling was conducted by Mountain Consulting for suspect coatings present with the building that produced negative results from XRF assay screening.

Mountain Consulting collected Twenty-Nine (29) bulk paint samples and Four (4) bulk glazed ceramic tile materials, representative samples from majority component painted surfaces or glazed ceramic tile materials that produced XRF results of less than 1.0 mg/cm².

March 25, 2014 LBP - Page 2 Mountain Consulting Services, LLC

The bulk paint & glazed ceramic tile material samples were submitted following proper chain-of-custody procedures to EMSL Analytical in Cinnaminson, New Jersey, for analysis by methods SW846, 3050*/7000B. EMSL Analytical, Inc. (phone 1-800-220-3675) is accredited by the American Industrial Hygiene Association. The accreditation certificate is provided in Appendix A.

3.0 RESULTS

3.1 XRF LBP SURVEY

LBP is defined by EPA regulations under Title X (Residential Lead-Based Paint Hazard Reduction Act of 1992) as containing lead concentrations above 1.0 mg/cm² when measured by a portable XRF instrument or 0.5% by weight (5,000 parts per million) when measured by laboratory analysis.

Since this project is ultimately to facilitate building re-occupancy and renovation and not HUD target housing, HUD regulations do not apply, although the procedures for XRF testing can be utilized effectively for lead positive screens. Unfortunately negative XRF assays for renovation or demolition project do require additional testing protocol.

The Occupational Safety and Health Administration (OSHA) does not have a definition for LBP, if any amount of lead is present in a material, OSHA worker-health-and-safety due diligence does apply.

Positive Results – A “positive” result refers to a sample that has a lead concentration greater than or equal to 1.0 mg/cm² by XRF analysis. See Appendix D for XRF confirmed positive assay results.

Negative Results – A “negative” result refers to a sample that has an average lead concentration of less than 1.0 mg/cm² by XRF analysis. Negative results indicate only that lead levels are below the action level by HUD regulations, within the precision limit of the machine. A “negative” XRF result does not mean that lead is not present under OSHA regulations. See tables of XRF Survey Results in Appendix E for a listing of all negative assays. Majority coatings that produced negative XRF assay results were bulk tested to verify actual lead content. Refer to Section 3.4 for the results of bulk coatings tested for lead content.

3.2 SUBSTRATE CONDITION

Mountain consulting made a visual assessment of the component sub-straights throughout the structure included for this project. Substrate conditions were fairly consistent throughout the facility for all tested coatings. The majority of interior substrates were in good serviceable conditions. The majority of exterior substrates were in fair to good conditions.

3.3 LEAD CONTAINING COATINGS BY XRF

The paint or ceramic tile glaze coatings associated with the following components are considered to be regulated lead containing materials by XRF Assay testing. These materials are potential lead hazards, contractors working on or around these materials should be informed of the lead content and potential lead hazard:

Components listed with deteriorated paint conditions should be subjected to lead hazard interim controls as soon as feasibly possible. Components listed to be in Intact condition did not constitute lead hazard at the time of this inspection. Lead hazards could emerge if the paint or tile glazing deteriorates or is impacted by renovation or demolition. Worker Health & Safety Lead Safe Work Practices should be employed for working with or around these components.

3.4 BULK COATING SAMPLE RESULTS

The Occupational Safety and Health Administration (OSHA) does not define by regulation a definition for lead based paint or lead glazing. The Housing & Urban Development (HUD) Federal Regulation action limit for the presence of lead by bulk paint analysis is 0.5 percent by weight (%wt.) for target housing only and therefore does not apply to renovation or demolition projects.

Mountain Consulting collected bulk paint and glazed ceramic tile samples for this project. Bulk coating samples were collected from majority coatings that produced negative XRF assay results.

The results of the bulk paint and glazed ceramic tile samples collected for this project are listed as follows by Building Area, Sample Number and Component Type: [Refer to Appendix F for laboratory report and chain of custody].

Notes: Bold-Italic = indicates non-regulated lead containing coatings.

• The result for bulk paint Samples: 1, 3, 6, 7, 12, 15, 16, 17, 21, 26, 27, 28, 29 and 30 confirm that these non-recyclable components are painted with regulated LBP or Lead Based Varnish ranging in lead content from 110 ppm to 83,000 ppm. If these components are to be impacted by renovation or demolition operations, contractor employees will require lead awareness trained personnel, utilizing lead safe work practices.

• The results for bulk paint Sample: 2, 4, 5, 10, 11, 13, 14, 31, 32, and 33 prove that these recyclable concrete & metal components are coated with regulated LBP ranging in lead content from 110 ppm to 380,000 ppm. If these components are to be impacted by renovation or demolition operations, contractor employees will require lead awareness trained personnel, utilizing lead safe work practices and materials may be recycled instead of disposal at a recycler that will accept the components with LBP present.

• The results for bulk paint Samples: 8, 9, 18, 19, 20, 22, 23, 24, and 25 prove that these paint and glazed ceramic tile components contain lead below 100 ppm and are not regulated for lead content by OSHA regulations.

4.0 RECOMMENDATIONS

All coatings identified as containing greater than 100 ppm lead from bulk paint analysis, proven LBP by XRF Assay Testing, or assumed be a regulated LBP associated with this project are governed by Federal regulations. Explanations of regulations are detailed as follows:

The Occupational Safety and Health Administration (OSHA) 29 CFR 1926.62 lead in construction standard does not define by regulation a definition for lead based paints, but does establish safe airborne exposure limits for employees working with lead containing materials to include paint films by PEL (permissible exposure limit).

The current PEL for airborne lead is 50ug/m³ (micrograms per cubic meter) and the current action limit (AL) is 30ug/m³.

If any material contains lead above the limit of detection by Flame Atomic Absorption (FAA) analysis (>0.01 %wt), proven to be a LBP by XRF testing or assumed lead containing then abatement, renovation or demolition contractors must demonstrate worker health and safety due diligence and lead safe work practices.

This would include lead awareness training for all affected employees, establishing proper employee personnel protective equipment (PPE), proper demarcation of effected work areas and performance of negative exposure assessment (NEA) lead air monitoring prior to downgrading any PPE.

The Federal Dangerous Waste Regulation (40 CFR Part 261 ) requires that lead containing materials with a lead content above 5,000 ppm threshold be treated as lead hazardous waste, until toxic characterization leeching procedure (TCLP) bulk waste stream sampling prove otherwise. The TCLP lead characterization threshold is 5 ppm.

TCLP bulk tested was not performed as part of this survey project. Future generated building waste streams that contain lead coatings with lead contents in excess of 5,000 ppm or greater than 1.0 micrograms per square centimeter (mg/cm²) will require TCLP testing prior to disposal to determine if the waste is hazardous waste or standard construction debris.

The metal and concrete components coated with LBP can either be abated prior to recycling or disposal; included with lead TCLP waste stream testing prior to disposed; or can be recycled at a facility that accepts metal materials with LBP present. If recycling is conducted full documented disclosure by all affected parties is recommended.

5.0 HEALTH EFFECTS OF LEAD EXPOSURE

For information concerning lead based paint and the health effects of lead, contact the National Lead Information Clearing House at 1-800-424-Lead.

Lead can be absorbed into the body by inhalation (breathing) and ingestion (eating or drinking).

Inhaling or ingesting even small amounts of lead can be harmful.

Lead poisoning can occur at high exposure concentrations (acute) or at low exposure concentrations over a long period of time (chronic) and can cause either temporary or permanent damage. Lead is a poison that accumulates in the blood, bones, and organs, including the kidneys, brain, and liver. It stays in the bones for decades and may be released slowly over time to cause toxic effects. An increasing blood-lead level usually means that there has been recent exposure and that lead is building up in the body faster than it is being eliminated. The early effects of lead poisoning are not specific and resemble flu-like illnesses.

Cumulative exposure to lead, which is typical in home settings, may result in damage to the blood, nervous system, kidneys, bones, heart, and reproductive system and contributes to high blood pressure. It is especially toxic to young children and women of childbearing age.

The symptoms of lead poisoning include the following:

• Headache • Sleeplessness

• Poor appetite • Hyperactivity

• Dizziness • Weakness

• Irritability or anxiety • Reproductive difficulties

• Constipation • Nausea

• Pallor • Fine tremors

• Excessive tiredness • Insomnia

• Numbness • “Lead line” on the gums

• Metallic taste in the mouth • “Wrist drop” [muscle weakness]

• Muscle or joint pain or soreness
