1.0 EXECUTIVE SUMMARY

As requested by the Navajo Area Indian Health Service (IHS), a Lead-Based Paint (LBP) inspection was conducted on the Kayenta Health Center within the Kayenta Service Unit located in Kayenta, Apache County, Arizona. Sampling occurred from February 13 to 22, 2012. The purpose of the inspection was to identify lead in paint on interior and exterior painted surfaces of each building. Measurements were made using a Niton X-ray Fluorescence (XRF) Spectrum Analyzer (Model XLp 303A). Specifications on this instrument are included in Appendix 5. Confirmatory chip sampling for laboratory analysis proved to be unnecessary due to the lack of indecisive XRF readings.

iiná, bá, Inc (iiná bá) representatives Mr. Vance Aspaas, Lead Inspector, and Mr. Nate Chase and Mr. Ted Charles, Technicians, performed the lead inspections. The inspector holds current a United States Environmental Protection Agency (USEPA) accredited 24-Hour Inspector Certification. A copy of the Certification can be found in Appendix 5.

Sampling procedures similar to the United States Department of Housing and Urban Development (HUD) Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing (June 1995), and revised in 1997, were followed for each of the buildings. Within each building or housing groups sampled, procedures similar to the HUD multi-family housing inspection, as outlined in Chapter 7 of the HUD Guidelines, were employed.

Lead-based painted building materials identified in the Kayenta Health Center buildings included the following: walls, doors, door trim, baseboards, ceilings, ceiling trim, cabinet doors, window sills, and exterior soffit). A total of 62 painted items were identified as containing lead-based paint in 11 out of the 48 buildings tested (23%).

3.0 SURVEY METHODS

3.1 XRF Instrumentation

Measurements of lead in paint were made using a Model XLp 303A ThermoFisher Scientific Niton XRF Spectrum Analyzer (serial number 26670). The XRF Lead Paint Analyzer non-destructively measures lead concentrations of painted surfaces. The XRF system includes three (3) main components: (1) the XRF analyzer, which is a portable analytical instrument operating on the principles of X-ray fluorescence; (2) forms for recording of field data, and (3) report generation software, which allows for generation of data tables.

The criteria for classifying results obtained using the XRF are as shown in Table 1 below. These results are taken from the HUD/EPA Performance Characteristics Sheet, specific for the XRF system used in this survey.

Table 1: LBP Classification Criteria, K-Shell Value

Substrate Negative Inconclusive Positive

Brick ≤0.9 None ≥1.0 Concrete ≤0.9 None ≥1.0 Drywall ≤0.9 None ≥1.0 Metal ≤0.9 None ≥1.0 Plaster ≤0.9 None ≥1.0 Wood ≤0.9 None ≥1.0

*Values reported as milligrams per square centimeter (mg/Cm2).

iiná bá, (as a firm) and its Lead Inspectors are licensed, as well as certified by the USEPA to perform LBP inspections. Copies of the certifications are included in Appendix 5.

3.2 XRF Calibration Check

Standard quality control procedures with respect to the XRF were performed during the survey. The internal calibration of the XRF was checked by taking a minimum of three

(3) consecutive measurements on a National Institute for Standards and Technology (NIST) standard with a known concentration of lead. The results of the calibration checks were then used to verify that the instrument was operating within acceptable limits. Periodic calibration checks were performed during the course of a day, specifically at the end of the day to “bracket” the test data collected between calibrations.

These calibration checks are reported within the XRF data tables found in Appendix 2 of this report and are maintained in a file to detect changes in instrument performance over time (sign of source deterioration).

3.3 Substrate Correction

For some XRF instruments, it is necessary to make corrections for bias in XRF readings made on some painted surface or “substrates”. In accordance with the HUD/EPA Performance Characteristics Sheet for the XRF analyzer used, it is not necessary to correct for substrate bias.

3.4 Field Documentation

Field data forms were used to manually record information about individual XRF measurements. This information included the room number, the building component (such as wall, ceiling, door, baseboard, cabinet, etc.), component substrate (e.g., drywall, wood, metal, concrete), and paint condition. The field data forms were then used by the inspector to couple measurement-specific descriptive information to the sequential data once the instrument’s electronic memory was downloaded to a personal computer. This information was then manipulated by the instrument’s software to generate data tables for the written report.

Any group of building units that were similar in construction from unit to unit with 21 of more units either built before 1960, are of an unknown age, or consist of 10 or more units built between 1960 and 1977 are defined as multi-family housing. Using this guideline, a random number of units were inspected.

Random number calculations were also allowed for sampling the large Kayenta Service Unit buildings, including the Health Clinic (Building 2000). At least one room in each designated area (Dental, Ophthalmology, Nursery, Administration, ER, Pharmacy, exam rooms, and bed areas. etc.) was examined, although the selection and screening of the room was obtained through random number calculations.

According to the HUD Guidelines, each enclosed space in a structure (e.g., room, stairway, hallway, etc.) is considered a separate "room equivalent" and must be tested separately. To keep track of where individual measurement locations were made, interior and exterior walls of a structure were designated as A, B, C, and D, as shown in the attached drawings. The A wall was designated as the wall facing the main road in this inspection, and the B, C, and D walls are in clockwise order from the A wall. The wall and position on the wall (i.e., left, right, or center) was also recorded when readings were taken on components such as windows or doors. Any comments regarding a particular room were also recorded and may be found in the data tables located in Appendix 2.

Paint color and condition are noted and included in the data tables. Under Paint Condition an "I" indicates intact or sound paint; an "F" indicates fair condition (paint surfaces show minor damage); a "P" indicates poor

The report generation software combined the lead readings stored in the XRF analyzer with the test sample location information recorded in the field to produce data tables.

The transfer of data from the analyzer to the computer was made through an interface cable supplied as part of the XRF system.

condition (paint is peeling, cracking, or blistering or shows other significant damage).

3.5 Dust Wipe Samples

Studies have shown the dust is an important pathway for lead exposure. Dust lead levels are the strongest predictor of children’s blood lead levels. The primary source is lead-based paint. The most likely place for lead dust to be found is on window sills and in window troughs.

Wipe sampling methods described by HUD, EPA, and the American Society for Testing and Materials (ASTM) (ASTM E 1728). Pre-packaged lead wipes were used to sample the window components. The area was measured for length and width and the area wiped in two directions by personnel wearing disposable gloves. The wipes were folded and placed in plastic baggies for shipping. Analysis was completed by Macs Labs in Grass Valley, California. The laboratory used the wiped area and the weight of the wipes and sample analysis to calculate the total amount of lead present. Dust wipe sample locations and levels are included in Table 3 in Appendix 3 with analytical results included in Appendix 4. Positive lead levels exceeding the HUD Guideline of 250 micrograms per square foot (µg/ft2) for window sill wipes were detected in seven (7) of the 36 locations tested. This includes Buildings 4001, 4002, 4008, 4015, 4018, 4021, and 4023. Interior dust lead levels can be reduced by conscientious housekeeping, including wet wiping of floors, window sills, and window troughs.

3.6 Soil Samples

Studies have shown that soil contaminated with lead contributes significantly to the blood lead levels found in children. Exposure can occur through direct ingestion of soil, “track-in” of soil into the dwelling interior, or through a combination of the two. The soil around a dwelling may be contaminated through weathering and “chalking” of lead-based paint on the building exterior. Soil can also be contaminated through airborne emissions from leaded gasoline and emissions from smelters and manufacturing plants.

Areas of high importance include drip lines around the housing unit.

At each housing unit sampled, possible contamination areas were located and samples taken to a depth of two (2) inches. The areas were generally barren of vegetation. The samples were composited in a single sample container. In most cases a minimum of three (3) samples were taken to make the composite sample. Once the samples were returned to the iiná bá’s Farmington office, the samples were dried, mixed and crushed.

They were then analyzed using the XRF and the sample results reported in parts per million (ppm) in Table 4. None of the 30 residential units sampled and screened for lead in soil tested positive for lead paint per HUD Guidelines.

4.0 LEAD-BASED PAINT DEFINITIONS

HUD considers paint to be lead-based paint (LBP) if the concentration is 1.0 milligram of lead per square centimeter (1.0 mg/cm2) or greater, or if the lead concentration is greater than 5000 parts per million (ppm) or 0.5% by weight. The Consumer Product Safety Commission (CPSC) currently considers paint to be lead-containing if the concentration of lead exceeds 600 ppm (0.06% by weight). In 1978, the CPSC banned the sale of lead-based paint to consumers and its application to areas where consumers have direct access to painted surfaces. This survey classified LBP on the basis of the HUD 1.0 mg/cm criteria and 0.5% by weight (5,000 ppm).

By contrast, the mission of the Occupational Safety and Health Administration (OSHA), with respect to lead in paint, is to protect workers during construction activities that may generate elevated airborne lead concentrations. OSHA states that construction work (including renovation, maintenance, and demolition) carried-out on structures coated with paints that have lead concentrations lower than the HUD or CPSC limits can still result in airborne lead concentrations in excess of regulatory limits. For this reason, OSHA has not defined lead-containing paint, but states that paint having any measurable level of lead may pose a substantial exposure hazard during construction work, depending upon the work performed. The owner or employers must be aware of the OSHA Lead in Construction Standard (29 CFR 1926.62) and the Respiratory Protection Standard (29 CFR 1910.134).

According to HUD Guidelines, lead-based paint was identified at or above 1.0 mg/cm2 on interior and exterior building components sampled during the survey. The Positive XRF Results Table (Table 2) in Appendix 3 identifies the room number, building component, paint color and condition, and approximate square footage of lead-based paint materials.

Detailed Cost Estimates (Appendix 3) were developed for the removal of lead based paint building components. The Detailed Cost Estimates were derived by abatement professionals utilizing current industry costs for the current period (2012). All applicable taxes and markup are included.

This estimate is for abatement contractor plus Environmental Professional costs. Costs for the replacement of building materials that have been removed are NOT included.

The total estimated cost for the chemical removal of lead based paint at the Kayenta Service Unit – Kayenta Health Center is $92,025.04. The total estimated cost for the component demolition of building materials applied with lead based paint at the Kayenta Service Unit – Kayenta Health Center is $71,126.42.

6.0 DISCUSSION AND RECOMMENDATIONS

Lead-based paint (LBP) was detected on interior and exterior building components during sampling conducted by iiná bá) on February 13 to February 22, 2012. The interior and exterior LBP components were generally in good condition, with some exterior deterioration. Due to the observed good condition of the LBP components, iiná bá) does not recommend abatement or maintenance attention to the LBP unless they will be disturbed by renovation or demolition activities.

The mere presence of LBP in a building poses no health hazard so long as the paint remains intact. Lead is only a hazard to adults and workers when it is inhaled, as fine dust or fume, or when it is ingested, when a painted surface is mouthed or chewed by a child, or inadvertently through contamination of surfaces, hands, and food by lead-contaminated dust. Therefore, to minimize the potential hazards associated with the presence of LBP, the following procedures should be implemented.

Identification (through testing) of all known or suspect LBP surfaces and communication of the presence of LBP surfaces to workers potentially affected by the presence of LBP.

Although the LBP testing has been completed, completion of a specific Operations and Maintenance (O&M) Program is suggested to organize a coherent, continuous program outlining procedures for routine inspections, maintenance, and immediate clean-up of damaged LBP surfaces. The O&M Program should address periodic inspections, maintenance activities, methods of safe and prompt clean-up when a licensed lead abatement contractor is not used, work procedures which are likely to create lead hazards, and a program of standard work procedures which are designed to minimize lead contamination. Development of an O&M Program was not part of iiná bá’s original Scope of Work. The on-site maintenance should perform periodic inspections to assess the condition of LBP (i.e. chip, peel, or flake). If areas of LBP become damaged or deteriorated, a licensed lead abatement contractor should be contacted regarding removal or abatement. Maintenance activities, which should be avoided in areas where known or suspect LBP is located, include, but are not limited to:

• Scraping, sanding, or using a heat gun on painted surfaces before repainting;

• Making holes in walls to access at pipes, install electrical outlets, etc.;

• Removing building components for renovation activities;

• Repeatedly bumping furniture or other objects into painted components;

• Unnecessarily opening and closing windows with LBP components. Major work or renovation performed on LBP components should be completed by a licensed LBP abatement contractor. However, if minor repair or immediate clean-up is necessary for a specific LBP component, at a minimum, the following work and clean-up procedures should be incorporated:

• Wet the painted surface with soapy water prior to working;

• Thoroughly clean area following work. Clean-up dust and chips with wet mops or rags soaked in a solution of trisodium phosphate (TSP) or phosphate containing powdered dishwashing detergent. Use two buckets of water – one for wash and one for rinse. To prevent recontamination of cleaned surfaces, wash mops and rags thoroughly after each use. Dust, chips, debris, mops, and rags should be contained in plastic bags and disposed of properly by a licensed lead abatement contractor;

• Avoid sweeping or vacuuming the work area. Sweeping and vacuuming spread lead dust particles, since the filters are not fine enough to contain LBP particles;

• If an entire LBP component (such as a window sill or door frame) requires removal, a representative sample should be taken of the LBP-coated component and this sample should be analyzed via the Toxic Characteristic Leaching Process (TCLP) method to determine whether the component must be disposed of as a hazardous waste. A licensed lead contractor should take the sample and a certifies, licensed laboratory should provide the analysis for the TCLP method;

There are three (3) general control strategies for controlling lead paint. These are component replacement, encapsulation, and paint removal. The most cost effective, up front control strategy is to encapsulate LBP by repainting areas of chipped, damaged, or deteriorating paint. Cleaning of the component and surface using procedures described above should be completed prior to encapsulation activities.

Safe and prompt clean-up of LBP debris or dust when damage of deterioration is encountered should be completed by a licensed lead abatement contractor when possible. LBP component removal and paint removal are considered LBP abatement and would need to b e completed by a licensed lead abatement contractor. Should removal or abatement be completed, an exposure assessment should be performed during the work, as required by the OSHA lead-in-construction standard.

iiná bá recommends personnel responsible for conducting maintenance of LBP components in the facility meet the training requirements for maintenance workers on LBP hazards. This training includes procedures that minimize lead dust generation and soil contamination during maintenance activities, as defined by the EPA and HUD. Portions of the OSHA 29 CFR 1910.1025 General Lead Industry Standard apply to the maintenance activities that involve making or keeping a structure, fixture, or foundation in proper condition in a routine, scheduled or anticipated fashion.

7.0 PROJECT LIMITATIONS

This project was performed using, as a minimum, practices consistent with standards acceptable within the industry at this time, and a level of diligence typically exercised by industrial hygiene and environmental consultants performing similar services.

The procedures used in this investigation attempt to establish a balance between the competing goals of limiting investigative and reporting costs and time, and reducing the uncertainty about unknown conditions. Therefore, because the findings of this report were derived from the scope, costs, time, and other limitations, the conclusions should not be construed as a guarantee that all environmental or occupational hazards have been identified and fully evaluated. Where sample collection and testing have been performed, iiná bá’s professional opinions are based in part on the interpretation of data from discrete sampling locations that may not represent conditions at non-sampled locations. iiná bá assumes no responsibility for omissions or errors resulting from inaccurate information, or data, provided by sources outside of iiná bá or from omissions or errors in public records.

Furthermore, it is emphasized that the final decision on how much risk to accept always remains with the client since iiná bá is not in a position to fully understand all of the client's needs. Clients with a greater aversion to risk may want to take additional actions while others, with less aversion to risk, may want to take no further action.
