The Inspector collected sampled of all identified building materials however, if additional materials are discovered during demolition those building materials must be sampled by a certified Building Inspector. Fifteen (15) samples were taken of the suspect building materials, as listed in the Lab Data table located on page 8 of this report. INSPECTOR QUALIFICATIONS This inspection was performed by Brian Guzman, Colorado State Department of Public Health and Environment Certification Number 21876. SAMPLE ANALYSIS PROCEDURE Suspect material was sampled and delivered under a chain of custody for analysis to Aerobiology Laboratory in Golden, CO. Samples were analyzed by Polarized Light Microscopy. TRANSMITTAL OF BUILDING/STRUCTURE ASBESTOS SURVEY INFORMATION One (1) copy of the results of the building/structure asbestos survey shall be immediately transmitted by the building/structure owner as follows:  One copy of the completed asbestos survey shall be sent by the owner or their agent to the local government entity charged with issuing a permit for such demolition, renovation, remodeling or repair work under applicable State or local laws.  The completed asbestos survey shall be kept on the construction site with the asbestos notification and variance, if required, throughout the duration of the asbestos project and any associated demolition, renovation, remodeling or repair project. The asbestos survey shall, at a minimum, identify and assess with due diligence, the locations, quantities, friability and conditions of all building material types at the affected portion of the building/structure. The certified asbestos inspector is responsible for identification and assessment of all type within the affected portion of the building/structure. All building materials visually assessed shall be assumed to be asbestos containing material (ACM), unless bulk sampling is conducted as per standard EPA and OSHA accepted 12/26/2018 GWS Office: (970) 945-4407 Aspen Office: (970) 925-3267 6690 Hwy 82, Glenwood Springs, CO 81601 401 Aspen Airport Business Center, Aspen, CO 81611 Email: info@ecosenvironmental.com www.ecosenvironmental.com methodologies. The subsequent analysis is performed by a laboratory that meets the requirements and the analyses satisfies both CO STATE ELAP and federal requirements, including multi- layered sample analyses, to document non-asbestos containing material. The building/structure asbestos survey shall also include the building/structure name, address, the building/structure owner’s name and address, the name and address of the owner's agent, the name of the firm performing the asbestos survey and a copy of the firm’s current asbestos handling license, the names of the certified inspector(s) performing the survey and a copy of the current asbestos handling certificate for each inspector utilized, the dates of the asbestos survey, a listing of homogeneous areas identifying which ones are ACM, all laboratory analysis reports for bulk samples collected, and copies of the appropriate certifications for the laboratory used for analysis of samples taken during the asbestos survey. REMOVAL REQUIREMENT If the building/structure asbestos survey finds that the portion of the building/structure to be demolished, renovated, remodeled, or have repair work contains asbestos containing material (ACM), which is impacted by the work, the owner or the owner’s agent shall conduct, or cause to have conducted, asbestos removal performed by a licensed asbestos abatement contractor in conformance with all standards set forth. All ACM impacted by the demolition, renovation, remodeling or repair project shall be removed, prior to access or disturbance by other uncertified trades or personnel. No demolition, renovation, remodeling or repair work shall be commenced by any owner or the owner’s agent prior to the completion of the asbestos abatement in accordance with the notification requirements. For multi-phased work, the access restriction for uncertified trades or personnel applies to each intermediate portion of the entire project. Upon completion of the intermediate portion of the asbestos project, other trades, or personnel may access that portion of the work site. For demolition projects that are exempt from asbestos survey requirements due to being structurally unsound, the demolition is considered an asbestos project. All building/structure owners and asbestos abatement contractors on a demolition, renovation, remodeling, or repair project shall inform all trades on the work site about the ACM at the work site. UNIDENTIFIED AND UNASSESSED ASBESTOS When any construction activity, such as demolition, remodeling, renovation or repair work, reveals suspect ACM that has not been identified by the asbestos survey, or has not been identified by other inspections as per current OSHA or EPA requirements, all activities shall cease in the area where the suspect ACM is found. Unassessed suspect miscellaneous ACM shall be treated and handled as ACM and assumed to be ACM, unless proven otherwise 12/26/2018 GWS Office: (970) 945-4407 Aspen Office: (970) 925-3267 6690 Hwy 82, Glenwood Springs, CO 81601 401 Aspen Airport Business Center, Aspen, CO 81611 Email: info@ecosenvironmental.com www.ecosenvironmental.com by standard EPA and OSHA accepted methods. To document non-asbestos containing material, analysis must be performed by a laboratory that meets the requirements of the DOH; and the analysis satisfies both CO STATE ELAP and federal requirements. ASBESTOS PROJECTS An asbestos project is any work that involves the removal, encapsulation, enclosure, repair or disturbance of friable or non-friable asbestos, or any handling of asbestos material that may result in the release of asbestos fibers. For the purpose of compliance an asbestos pro ject shall include any disturbance of asbestos fibers, and the planning, asbestos survey, design, background air sampling, inspection, air sampling and oversight of abatement work, cleanup, and the handling of all asbestos material subject to abatement, as well as the supervising of such activities. An asbestos project starts with Phase I when the planning, asbestos survey, and design work begins or is required to begin. The project shall not be considered completed until Phase II D is complete.

Amosite is the common name for the asbestiform variety of the minerals cummingtonite and grunerite. Crocidolite is the common name used for the asbestiform variety of the mineral riebeckite.  Tile, vinyl, foam, plastic, and fine powder samples may contain asbestos fibers of such small diameter (< 0.25 microns in diameter) that these fibers cannot be detected by PLM. For such samples, more sensitive analytical methods (e.g. TEM, SEM, and XRD) are recommended if greater certainty about asbestos content is required. Semi-quantitative bulk TEM floor tile analysis is accepted under NESHAP regulations.        These results are submitted pursuant to Aerobiology Laboratory Associates, Inc.’s current terms and conditions of sale, including the company’s standard warranty and limitation  of liability provisions. No responsibility or liability is assumed for the manner in which the results are used or interpreted.  Unless notified in writing to return the samples covered by this report, Aerobiology Laboratory Associates, Inc. will store the samples for a minimum period of thirty (30) days before discarding. A shipping and handling charge will be assessed for the return of any samples.  Aerobiology does not guarantee the results of tape lifts, microvacs, wipe, and/or debris samples. Accurate analysis cannot be performed due to particle size, media used, and/or amount of material given. Analysis of these materials should be preformed by a TEM. A result of ND does not indicate that the sample area does not contain asbestos. It means the analyst could not identify asbestos in the specific sample for the reasons listed above.
