EXECUTIVE SUMMARY

At the request of the Forest Service (FS) and the FS’s acceptance of Matrix New World

Engineering, Inc.’s (Matrix) proposal dated March 18, 2015, Matrix is providing this Asbestos

Report of Findings and TCLP Survey for the vacant single family structure, outhouse and dog house located at Long Lake in the Coconino National Forest, Arizona. Our survey is intended to provide information to the FS regarding the presence and location of asbestos-containing materials (ACM) in the structure and to characterize the demolition debris as either Hazardous waste or solid waste.

On March 19, 2015, Mr. Matt Valenti performed the field portion of the Asbestos and TCLP survey at the subject site. During the field portion of the project, 12 suspect asbestos containing materials were observed and 36 samples were collected from the different suspect homogenous materials. Samples were delivered to a NVLAP accredited laboratory for analysis by Polarized Light Microscopy (PLM). In addition, Mr. Valenti collected a composite TCLP sample to characterize the demolition debris as either Hazardous or Solid waste.

Of the 12 suspect materials identified by Matrix, two of the materials were determined by laboratory analysis to contain asbestos in excess of one percent.

The results of the TCLP sample collected at this site (single family structure outhouse & dog house) was positive for concentrations of Lead above the EPA concentration of 5.0 mg/l of lead leachate. Based on the results of the Lead TCLP sample, waste generated from the demolition of this site would be characterized as hazardous waste.

PROJECT INFORMATION

The property that is the subject of this report is a vacant single family structure, outhouse and dog house, located at Long Lake in the Coconino National Forest, Arizona. The single family structure is constructed of stone perimeter walls and concrete floors and wood roof trusses. The outhouse is constructed of wood with metal roofing and the doghouse is wood with asphalt shingle roofing. Our understanding is that the subject structures are scheduled for demolition.

1.0 SCOPE

The purpose of the asbestos survey was to locate, inventory and assess asbestos-containing materials (ACM) as to type, condition and percent of asbestos content, and friability that would be impacted during planned demolition activities. Our services included a physical inspection, and the collection and analysis of samples of suspect materials to determine the presence of asbestiform minerals in the subject buildings. Homogeneous areas of suspect materials were classified as Surfacing, Thermal System Insulation (TSI) or

Miscellaneous, in accordance with the Asbestos Hazard Emergency Response Act

(AHERA) protocol. Additionally, identified suspect materials were physically evaluated to determine friability. “Friable” materials are those which when dry can be crumbled, pulverized, or reduced to powder by hand pressure.

The survey included the identification of both friable and non-friable materials used in the construction of the subject property. These materials were classified as Regulated ACM

(RACM), Category I non-friable ACM, or Category II non-friable ACM in accordance with

National Emission Standard for Hazardous Air Pollutants (NESHAP) regulations.

2.0 SURVEY PROCEDURES

The field portion of our work included a visual survey of the subject property and the collection and analysis of samples of suspect ACM. The single family structure was vacant at the time of our survey. The field portion of the work was conducted on March

19, 2015 by Mr. Matt Valenti, a certified EPA Building Inspector. See Appendix D for a copy of the personnel certification.

2.1 Document Review

No asbestos reports were made available to us prior to conducting the survey.

2.2 Walk-Through and Observations

The field portion of the survey included the observation of interior and exterior finishes to identify and locate accessible suspect ACM at the subject property. Suspect ACM are defined as those classes of materials which have, in the past, been known to contain asbestos in some formulations. In surveying the subject property, we have used our training in identifying suspect ACM, our familiarity with building construction and our general engineering experience to locate potential sources of ACM.

During our walk-through, suspect materials were noted and grouped by homogeneous area.

A “homogeneous area” (for bulk sampling purposes) is defined as an area that contains building materials, suspected of containing asbestos, that seem by texture, color, and wear to be uniform and applied or installed during the same general time period. Our inspector also evaluated the friability of each material by physically touching each of the suspect materials. The general physical condition of suspect materials was noted during the walk-through. The suspect materials observed were found to be generally accessible.

The materials listed below were identified during the survey. The two digit number preceding the material description indicates the Homogeneous Area number assigned to each material. Materials found to be ACM are denoted in bold.

01 – Residual Mastic, black 02 – Joint Compound, white (on fiber board) 03 – Plaster, white 04 – Brick & Mortar, gray/yellow 05 – Window Glazing Putty, tan 06 – Bituminous Roof Shingles, green/red/black 07 – Mortar (exterior wall), gray 08 – Mortar (fireplace), gray 09 – Concrete (house slab), red/gray 10 – Concrete (front porch foundation and exterior perimeter of house) grey 11 – Mastic (exterior SW), grey 12 – Bituminous Roof Shingles (dog house), red

The outhouse had no suspect asbestos containing materials to sample.

2.3 Bulk Sampling

Following delineation of homogeneous sampling areas, bulk samples were collected from suspect materials at random locations. For each homogeneous area sampled, the quantity of samples collected was determined in general accordance with the AHERA sampling protocol. A total of 36 bulk samples were collected from the suspect materials identified during the survey. Samples were labeled and appropriate chain-of-custody documentation was completed.

Samples were collected from readily accessible construction materials which were representative of the general construction of the buildings, and which were considered suspect ACM. Destructive activity, such as breaking through walls or ceilings was performed in order to collect samples. Samples were delivered to Cates Laboratories for visual inspection and microscopic analysis.

2.4 Bulk Sample Analysis

Samples were analyzed using Polarized Light Microscopy (PLM) coupled with dispersion staining. Analysis was performed in general accordance with the procedures outlined in the

United States Environmental Protection Agency’s (EPA) “Method for the Determination of

Asbestos in Bulk Building Materials” (EPA/600/R-93/116, July 1993). The laboratory analysis of each bulk sample relates only to the material tested, and may or may not represent the overall composition of the homogeneous area in question. Bulk samples were analyzed by Cates Laboratories (PLM), an accredited laboratory under the National

Voluntary Laboratory Accreditation Program (NVLAP). PLM is the EPA recommended method for bulk sample analysis, and uses the unique optical and crystallographic properties of the various constituents of the samples. The percentage quantification of individual sample constituents was determined by visual estimation.

Non-homogeneous constituents of layered samples were analyzed as separate layers, and the percentage of each material component, including asbestos content, was combined to represent the total sample composition. Under regulations promulgated by the EPA, asbestos-containing materials are defined as those materials which contain more than one percent asbestiform minerals.

Bulk samples determined to contain more than one percent asbestiform minerals are referred to as “positive”. However, a minimum of three samples are necessary, by EPA guidelines, to confirm a negative or non-asbestos result for a homogeneous area. Further more the City requires that all friable samples determined to be ≤ 5% asbestos by PLM be

Point Counted and all non-friable organically bound materials (i.e. vinyl asbestos tile/mastic) that are determined by PLM to be ≤ 1% asbestos-containing will have one sample of each material analyzed by Transmission Electron Microscopy (TEM).

3.0 SUMMARY OF FINDINGS

Of the 12 suspect materials identified by Matrix, two of the materials was determined by laboratory analysis to contain asbestos in excess of one percent. Laboratory PLM

Analysis Summary and PLM Analysis Detail Sheets are included in Appendix C.

4.0 QUALIFICATIONS

Matrix has endeavored to observe the existing conditions at the subject property using generally accepted procedures and that degree of care and skill ordinarily exercised under similar circumstances, by reputable consultants practicing in this or similar locations.

Regardless of the thoroughness of any survey, there is always a possibility some areas containing asbestos may be overlooked, are inaccessible, or are different from those at specific sample locations. Therefore, conditions at every location may not be as anticipated. In performing the survey, no attempt was made to dismantle equipment for the purpose of obtaining samples. Wall voids, building cavities and mechanical equipment parts may contain unreported asbestos. The findings presented in this report are relevant to the dates of our site work and the scope of included services, and should not be relied on to represent conditions at substantially later dates.

5.0 TOXICITY CHARACTERISTIC LEACHING PROCEDURE

The purpose of the Toxicity Characteristic Leaching Procedure (TCLP) is to characterize the demolition debris as either Hazardous waste or solid waste. A TCLP composite sample is accomplished by collecting representative painted building components including the substrate (wood, fiber board and plaster). These materials are all placed in one airtight container an appropriate chain of custody is completed and delivered to a Lab for TCLP for analysis in accordance with EPA SW-846 Method 1311 and appropriate EPA 6010B. The

TCLP analysis simulates landfill conditions. Over time, water and other liquids percolate through landfills. The percolating liquid often reacts with the solid waste in the landfill, and may pose public and environmental health risks because of the contaminants it absorbs.

The TCLP analysis determines which of the contaminants identified by the United States

Environmental Protection Agency (EPA) are present in the leachate and their concentrations, in this case Lead. The TCLP procedure consists of a solid waste

(composite sample) that the sample is reduced in size to pass through a 9.5mm standard sieve and leached in an acid solution for 18 hours and the resulting leachate is analyzed.

The results of the TCLP collected at this site was positive (6.2 mg/L) for concentrations of

Lead above the EPA concentration of 5.0 mg/l of lead leachate. Based on the results of the

Lead TCLP sample, waste generated from the demolition of this site would be characterized as hazardous waste. Results of the TCLP sample are included in Appendix C.
