Susan and Alyssa, This report provides information regarding an asbestos building material survey performed at the pump house building at the San Luis Lakes State Wildlife Area located at 16399 Lane 6 N near Mosca, CO 81146. The sampling was conducted in an effort to determine the asbestos content of suspect materials in the roofing materials prior to its removal and replacement. The 40’ x 50‘ building contains 2000 sf of roofing materials. A repair of 450 sf is present toward the SE part of the roof.

Donald Stephens of Asbestos Inspector, LLC is a Certified Asbestos Building Inspector in the State of Colorado and conducted the asbestos sampling.

Eurofins EMLab P & K Laboratory, an independent laboratory accredited by the National Voluntary Accreditation Program (NVLAP) and the American Industrial Hygiene Association (AIHA) analyzed the samples utilizing Polarized Light Microscopy (PLM).

Bulk sampling of suspect building materials was conducted to identify any Asbestos Containing Material (ACM). An ACM is defined by the EPA as a material with an asbestos content of greater than 1% by area. Select bulk samples of suspect building materials were collected throughout the residence. Bulk samples of suspect building materials were collected and analyzed.

Description of Suspect Building Materials

The roof is composed of several layers of varying materials including black membrane with coatings, foam insulation panels, and tar paper. There is repair over these materials along the SE edge of the roof that has an additional of rolled asphalt and tar. A white layer was applied in various areas, which was included in all samples. A wood substrate is visible on the underside of the roof from within the building. All sample locations above reached the wood substrate.

Homogenous Areas (HA) are defined by CDPHE Regulation 8 as an area of surfacing, miscellaneous, or thermal insulation system materials that are uniform in color and texture. Suspect ACM building materials are listed in the following table:

Homogenous Area

Material Type Condition Quantity

HA-1

HA-2

A total of 5 samples were collected during the inspection. None of these materials were assumed to be asbestos containing. Samples were acquired of all identified suspect materials and submitted for analysis. They are listed in the following table:

Findings — None of the potential ACM’s were found to contain asbestos. No further actions are required and the roof repair may proceed without any further actions. There will be no structural materials disturbed during the roof replacement, thus no CDPHR demolition application is required.

Recommendations

No ACM’s were identified within the structure, no further actions are required.

The Colorado Department of Public Health and Environment (CDPHE) defines an asbestos containing material as a material containing greater than 1% asbestos, removal in accordance with the CDPHE Regulation No. 8, is required of asbestos containing materials that are friable or will be made friable during renovation or demolition activities. Friable means that the material, when dry may be crumbled, pulverized, or reduced to powder by hand pressure.

When asbestos is found in any concentration, requirements set forth in the Occupational Safety and Health Administration’s Construction Asbestos Standard, 29 CFR 1926.1101 must also be followed when handling asbestos containing material.

This survey is to identify locations of ACM and shall, under no circumstances, be considered recommendations for project design.

Limitations:

Please Note: Additional suspect asbestos containing materials may exist under/behind building materials that were not sampled. If additional suspect ACM is uncovered through demolition that are not listed on this survey as tested, WORK SHOULD STOP and they should be presumed to be asbestos containing until further sampling and analysis proves otherwise.

This report describes the locations and conditions of ACM identified in the facility during the inspection.
