1.0 EXECUTIVE SUMMARY

As requested by the Navajo Area Indian Health Service (IHS), a Lead-Based Paint (LBP) inspection was conducted on the Crownpoint Health Care Center within the Crownpoint Service Unit located in Crownpoint, McKinley County, New Mexico. Sampling occurred between January 18, 2012 and February 2, 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 Ms. Judy Moore and Mr. Vance Aspaas, Lead Inspectors, 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.

2.0 DESCRIPTION OF BUILDINGS INSPECTED

Buildings 34 and 65 are pre-1960 housing with basements. They are nearly identical in arrangement and building materials. The houses have cement block foundations with wood frames. The exteriors are stucco with covered front porches. There is fairly new red propane roofing on both houses.

The interiors are a combination of drywall and plaster walls and ceilings. The ceilings in the bathrooms are 12 inch by 12 inch (in.) wood tile adhered to the drywall with brown mastic. There is a rock and brick fireplace in the main living area of each house. The windows are coated metal set in metal frames. There are usually wood window shelves on the interior windows. The floors are wood substrate with 12 in. by 12 in. tiles or carpeting. Vinyl cove base is found in the kitchen and some bedrooms, and wood baseboard in found in the units’ living areas. Fire doors are used at both front and back entrances.

Building 65 is in very poor condition with the porch near collapse. The flooring has been removed from most of the house leaving the wood subfloor (or original floor) and some carpet and tile remnants. This house is currently used for storage.

Building 34 is in fair condition with some exterior crack and stucco damage indicating possible structural damage. This house is currently occupied.

Buildings 35 and 66 are garage units associated with housing units 34 and 65, respectively. Both have unfinished wood frame interiors, and rock and stucco exteriors.

They both have flat roofs that are layers of tar paper shingles and rubberized roofing material. Building 34 is a 4-bay garage in fair condition. Building 66 is a single bay garage in poor condition with evidence of water damage.

Building 36 is similar to Buildings 34 and 65. It is used as an office for the Office of Environmental Health. It is a stucco and cement block building with a combination of plaster and drywall interior. Fire doors are found at both front and back entrances.

Building 2000 is the 79,112 square foot (ft.) Crownpoint Health Center. The building is wood and metal frame on cement foundation. The exterior has carved rock siding on the lower portion of the building. There are raised walls in the hallways that contain windows to provide natural light. These exterior raised wall areas are stucco. All walls have brown pro-panel on the building’s upper two feet.

The interior walls are drywall. The ceilings are a combination of drywall and hanging 2

ft. by 4 ft. and 2 ft. by 2 ft. ceiling tiles. The flooring is 12 in. by 12 in. floor tiles or 18 in.

by 18 in. carpet tiles. Many of the carpet tiles are new and were being laid during inspection. Some rooms have older two-tone blue carpet that is dates from building construction. The main patient waiting area has a manufactured stone floor tile laid in patterns. Vinyl cove base was used throughout the building. Fire doors are found throughout the building.

Buildings 2001 through 2016 are pre-1960 housing units that are 2 or 3 bedroom.

Some are duplexes, most are single family units. They are wood frame on cement slabs with stucco exteriors. The interiors are drywall walls and ceilings. Most units have unfinished garages with drywall storage closets. All units have recently placed pro-panel roofing. The windows are coated and uncoated metal with metal frames and wood window shelves. The flooring is 12 in. by 12 in. floor tiles. The units had a mix of cove base and wood baseboards. Exterior doors are both metal and wood.

Buildings 2017 to 2034 are wood frame houses on cement foundations dating from the 1980’s. There are individual housing units, duplexes, and four-plexes. They have brick and wood exteriors with pro-panel roofing and gutter systems. All but the four-plexes have finished garages. The interiors have drywall walls and ceilings. Flooring varies as many residents have replaced the original flooring with their own options. Most flooring is 12 in. by 12 in. floor tile in the kitchen and bathroom, and carpeting in the remainder of the house. Some residents had remodeled their unit using linoleum or ceramic tiles in the kitchens and bathrooms. The units had a mix of cove base and wood baseboards.

Exterior doors are generally metal.

Buildings 3000 to 3003 are modular duplexes built within the last ten years. Random sampling was conducted in all eight units at the request of the contracting Officer Technical Representative (COTR) to confirm non-ACM building materials were used.

The units have pro-panel siding over wood frame and are set on cement block foundations. The roofing is pro-panel with black penetration rubber and tar. The interiors are drywall walls and ceilings. The flooring is linoleum in the bathrooms, kitchens, and laundry areas, and carpet throughout the remainder of the house. All units have vinyl cove base.

Building 3004 is a double-wide trailer set on a cement foundation and used as a physical fitness center for hospital staff. It is wood framed with metal exterior wall panels and metal window shutters. The roof is a rubberized system over foam insulation and metal substrate. There is no shed or cement parking area attached to the building.

The building interior is wood panel with wood panel ceiling tiles 2 ft. wide by 6 ft. long.

Although the building has a kitchen area, the only other rooms are the large workout area, an entrance off the back door and the restroom. The flooring is 12 in. by 12 in. tile over wood substrate. Wood baseboards were found throughout the building.

Buildings 3017 to 3047 were built in the 1960s and 1970s. They are wood-framed, double-wide trailers set on cement foundations with wood frame sheds attached. The exteriors are painted metal with metal window shutters, metal awnings over parking areas, and metal roof trim. The roofs are rubberized with foam insulation over metal.

The interiors are wood paneling and wood panel ceiling tiles 2 ft. wide and approximately 6 ft. long. The flooring is 12 in. by 12 in. tiles laid over an older layer of 12 in. by 12 in.

tiles over a wood substrate. In some units carpeting was found over the floor tiles in the living and bedroom areas. Most units have wood crown molding and wood baseboards.

Vinyl cove base was found in some buildings. The exterior doors are generally metal.

Building 3601 is a metal framed building with uncoated, corrugated metal siding and roofing. The interior is unfinished. There is one wood door and one metal garage door lined with plywood sheeting.

Building 3602 is a large metal framed building with painted metal siding and roofing set on a cement slab. The interior is generally unfinished with fiberglass insulation visible on the walls and ceilings. Two small rooms are nested inside one of the two large interior rooms. One smaller room is the restroom with 12 in. by 12 in. floor tiles and finished drywall ceiling and walls. The other attached room is a partially finished locker room with floor tiles. The remaining floors are painted cement. All exterior doors are metal.

Building 4005 has been demolished.

Building 4006 is a modular office building set on cement block foundation. The exterior is metal siding and trim with rubberized roofing over foam insulation and metal substrate.

The interior is drywall walls and ceilings with 12 in. by 12 in. floor tiles over wood substrate. There is vinyl cove base throughout the building and metal exterior doors. All bkemmet Rectangle Only 3019-3047 staff quarters are in contract bkemmet

In Contract building insulation found was fiberglass. Walls and ceilings were checked for vermiculite insulation and none was found. All plumbing was cast iron or PVC piping. No transite piping was observed.

Lead-based painted building materials identified in the Crownpoint Health Care Facility buildings included the following: selected white and green painted walls, window sills, door trim, baseboards, shelves, cabinets/cabinet trim, brown doors and door trim, blue walls, tan and purple walls, window sills, and red exterior painted items (soffit, support beams, door trim, and roof trim). A total of 334 painted items were identified as containing lead-based paint in 16 out of the 61 buildings tested (26%).

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 by the State of New Mexico Environmental Department, Radiation Control Bureau, 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 dorms 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. In the Crownpoint Service Unit housing, there are five (5) multi-family housing units. They are as follows:

1. Housing units 34 and 65 and associated garage units 35 and 66 were built pre- 1950.

2. Housing units 2001 through 2016 were built pre-1960.

3. Housing units 2017 through 2034 built after 1960 and before 1977.

4. Housing Units 3017 through 3047 were built after 1980.

5. Housing Units 3000 to 3003 were built in approximately 2004.

Random number calculations were also allowed for sampling the large Crownpoint Service Units, 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 with analytical results included in Appendix 4.

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.

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).

6.0 DISCUSSION AND RECOMMENDATIONS

Lead-based paint (LBP) was detected on interior and exterior building components during sampling conducted by iiná bá) on January 18 to February 2, 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 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.

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.
