1.0 EXECUTIVE SUMMARY

ACT Environmental Inc., (AEI) performed a lead-based paint (LBP), lead-containing material (LCM) and asbestos inspection of a home located at 9818 Pinery Canyon Road, Willcox, Arizona. The building is owned by the National Park Service. AEl is a registered environmental engineering consulting firm under contract to perform consulting services including LBP and asbestos inspections.

The scope of the inspection included all interior and exterior areas of the building. The inspection included one single story 1,800 square foot building plus a metal storage building.

The inspection was conducted on August 23, 2016. The inspection was performed by an EPA certified LBP inspector and Asbestos Hazard Emergency Response Act (AHERA) accredited inspector. One hundred forty nine (149) LBP sampling areas were tested for lead content. Lead testing was performed using a portable X-ray fluorescence analyzer. Fifty (50) samples of suspect asbestos-containing materials were analyzed.

LBP, LCM and asbestos containing building materials were identified.

2.0 INTRODUCTION

This inspection was performed at the request of the National Park Service. The intent of the inspection was to perform a LBP and asbestos inspection of building materials that may be impacted by building renovation.

3.0 SCOPE OF WORK

The scope of the project was to perform a LBP, LCM and asbestos inspection of all building materials on the interior and exterior of the building.

Asbestos bulk samples were submitted to Desert Analytical Services (DAS). The analysis was performed in accordance with EPA Test Method EPA-600/R-93/116. DAS is rated proficient in the AIHA Bulk Asbestos Proficiency Analytical Testing Program lab #198554. Copies of laboratory reports are included in Appendix A.

4.0 TESTING PROCEDURES

LBP/LCM Inspection-

Selected sites in the building area including all walls and each type of component were surveyed for the presence ofLBP/LCM using a spectrum analyzer portable X-Ray fluorescence (XRF) paint tester. The XRF unit was a Niton Xlp 300A. The analyzer reads the lead content non-destructively without collection of physical samples or stripping of paint. The analyzer automatically reads the lead content which gives an instantaneous readout oflead content. The instrument is calibrated every four hours or less.

Prior to testing, a review was performed. Buildings with common construction and painting history were identified. The testing protocol uses a north, south, east and west system for both interior and exterior walls.

Asbestos Inspection-

Random and/or convenience samples of suspect asbestos-containing materials were collected.

Random sample locations were determined in accordance with EPA's guidance document EPA560/5-85-030a, October 1985, Asbestos in Buildings: Simplified Sampling Scheme for Friable Surfacing materials. All testing utensils such as chisels, drills, and knives were cleaned between collection of each sample. Each sample container was labeled with a sequential ID# and also noted in the bulk sample log.

Suspect asbestos-containing materials in each building were categorized into homogeneous sampling areas. Homogeneous sampling areas are those areas which contain similar suspect materials. Similar materials are those which have the same physical appearance and appear to be applied at the same time using the same methods.

Chain of custody was initiated at the time of sample collection. Samples were hand delivered to the lab. Upon delivery to the lab, the samples are logged by the lab. At that point, the chain of custody became the responsibility of the lab.

All accessible areas were inspected. Despite efforts to identify all suspect asbestos-containing materials, additional suspect materials may be concealed by building components. Examples of these materials include piping concealed between walls, fire proofing, Transite panels and duct seam tape. If suspect materials are found, they should be assumed to contain asbestos unless further testing proves otherwise.

5.0 BUILDING DESCRIPTION

The original date of construction is estimated to be 1910. The home appeared to be recently renovated.

Buildings built prior to 1978 may contain LBP. The owner is the National Park Service.

The home is a single story building approximately 1,800 square foot building. A 300 square foot metal storage building is located north of the home. The home is constructed with stone walls and wood framing.

The roof is constructed with metal. The home has a crawl space below with a dirt floor. The home has an attic. Interior ceilings and walls are constructed with Sheetrock. The floors are a wood and vinyl floor tile.

The doors and door frames are wood. The original windows are steel-frame. New aluminum windows have been attached to the original windows.

6.0 FINDINGS

LBP and LCM was found including:

l. Room 3 Living room/dining room- The east French door. The main entrance, west side, door jamb.

2. Room 4 Hall Bathroom- The pink and black ceramic tile walls. Ceramic tile is classified as LCM.

3. Room 6 Laundry Bathroom- The pink and black ceramic tile walls. The ceramic tile is classified as LCM.

4. Room 7 Laundry room- The east exterior door jamb.

5. Room 8 Kitchen- The south exterior door jamb.

A(M

No other LBP or LCM was found.

Asbestos containing materials (asbestos content greater than 1%) found including:

I) 300 square feet of resilient flooring. The flooring is located in the hall bathroom room 4, laundry bathroom, room 6, laundry room 7, and kitchen room 8, This includes the bottom layers of resilient flooring found below newer 6"X6" and l 2"X12" vinyl floor tile. The bottom asbestos containing flooring includes beige/white floor tile with black adhesive attached to the original wood floor.

Some areas have a new wood underlayment applied to the original wood sub-floor. The flooring is categorized as Category I and II non-friable material, under the U.S. EPA NESHAP regulation.

2) 50 square feet of black roofing sealant, This includes black sealants applied to metal seams and roof penetrations. The roofing is categorized as Category I non-friable material, under the U.S. EPA NESHAP regulation.

3) 13 square feet of duct seam tape. The seam tape is applied to HVAC ducts found in the furnace room 5. The seam tape is also assumed to be found in the attic and crawl space on HVAC ducting.

The material is categorized as friable RACM under the U.S. EPA NESHAP regulation.

4) 50 square feet of exterior widow glazing is assumed to contain asbestos. The glazing is found on the original steel-frame windows. The glazing is found on the exterior glass window panes.

These panes are incased by new aluminum framed windows and could not be sampled without damaging the window system. The glazing is classified as RACM under the U.S. EPA NESHAP regulation.

Note: The interior Sheetrock texture/joint compound was reported to contain trace levels of asbestos, <I% asbestos. Therefore, the EPA does not consider it to be an asbestos-containing material. However, OSHA has minimal work practice requirements and prohibitions for trace levels of asbestos. These OSHA work practices require the use of wet methods, or wetting agents, prompt clean-up and disposal of waste in leak-tight containers. OSHA prohibits the use of high-speed abrasive disc saws and the use of compressed air to remove materials containing asbestos.

7.0 RECOMMENDATIONS/CONCLUSIONS

Asbestos building materials within the building include roofing, window glazing, flooring and duct seam tape. The materials do not present a health hazard in the undisturbed condition. The material should remain in place until a major renovation or demolition occurs. The EPA requires removal of these materials if the materials would be disturbed during renovation activities.

LBP and LCM were found on building components. LBP and LCM are in good condition and do not present a health hazard. The condition of the LBP and LCM should be monitored to assure it remains in good condition. lfLBP and LCM building components are disturbed, the work should be performed in accordance EPA's lead safe work practices and in compliance with the OSHA lead standard. Contractors performing work must be certified by the EPA for lead renovation, repair and painting work.

William F. Martin and Nate Pfister perfonned the inspections. One additional technician assisted with the inspections. Mr. William F. Martin is a certified industrial hygienist, an EPA certified lead inspector/risk assessor and an EPA accredited asbestos inspector. Mr. Pfister is an EPA accredited asbestos inspector.

9.0 LIMITATIONS

Every effort was made to locate asbestos-containing materials. Specific limitations applicable to this inspection include the following:

Some areas of the building, such as between walls and above the ceiling, were not accessible. Examples of asbestos-containing materials which may be present in these inaccessible areas include duct tape, pipe insulation, fire proofing, Transite pipes and Transite panels.

Paint containing less than 1.0 mg per square centimeter is considered "lead free" by the EPA. OSHA has not adopted the EPA "lead free" definition and does not have a regulatory threshold for lead content.

This inspection was perfonned in accordance with existing standards and acceptable practices. Every reasonable effort was made to identify all suspect asbestos-containing materials located in the building.
