Mulberry Ave. Ft. Collins, Colorado. The purpose of the limited inspection was to identify and sample potentially hazardous friable and non - friable ACM that may be impacted by subsequent remodeling activities. 2.0 Scope of Work The scope of the limited inspection and bulk -sampling was limited to specific areas of the residence defined by the construction company. These areas included the NE bedroom, hall bathroom, laundry area and bathroom on the main level. The remaining areas within the residence, garage or any out -building on the property were not included in the scope of the inspection. The limited asbestos inspection did not constitute a full building inspection and does not fulfill the asbestos inspection requirements for structures that are to be demolished. 3.0 Site Description The residence is a wood -framed, single-family residence. 4.0 Certifications The limited asbestos inspection and bulk -sampling was conducted by Andy Dunnell with Banyan Environmental is a Colorado Department of Public Health and Environment (CDPHE) certified Asbestos Consulting Firm, Registration No.16780. Mr. Dunnell is a CDPHE certified Building Inspector; having certification number 15895 5.0 Inspection, Sampling & Analytical Procedures 5.1 Inspection Procedures The limited asbestos inspection was conducted by an Environmental Protection Agency (EPA) and CDPHE certified Building Inspector. The inspection procedures included identifying and sampling suspect ACM within the pre -defined areas, submitting samples to an accredited laboratory for analysis, classifying the materials and assessing their condition, and compiling a final report detailing the inspection and the analytical results of the bulk -samples. 5.2 Sampling Procedures Statistically random bulk -samples representative of the suspect ACM of each homogeneous area were collected according to the guidelines published as EPA Final Rule: Title II of the Toxic Substances Control Act (TSCA),15 USC, Sections 2641 through 2654 and in compliance with 40 CFR, Part 763 and CDPHE Regulation Number 8, Part B- Asbestos (Reg. 8). Banyan Environmental has collected the appropriate number of bulk -samples to meet all regulatory requirements for the classification and quantity of each homogeneous area. Some minor destructive sampling was conducted; however, walls, columns and perimeter pipe chases were not broken into in order to locate and quantify suspect ACM. Banyan is not responsible for repairing the damage from collecting bulk samples. It should be noted that additional ACM might be located in these and other inaccessible areas. Materials containing less than 1% asbestos are not regulated by CDPHE Regulation 8, Part B - Asbestos. However, all demolition/abatement activities should be performed following the applicable Occupational Safety and Health Administration (OSHA) regulations. This would include, but not limited to, the appropriate asbestos training for the type of material being removed/disturbed as well as having a properly trained supervisor onsite, using wet removal methods, wearing adequate personal protective equipment (HEPA-filtered particulate respirators), medical surveillance of workers, personal -exposure air monitoring, area air monitoring in occupied buildings, etc. There may also be landfill disposal requirements for these materials, depending on the facility. Banyan recommends that all demolition/renovation areas involving any amount of asbestos be subjected to visual inspections and a final clearance air testing by a CDPHE-certified Air Monitoring Specialist (AMS) after the work has been completed, but before any containments are dismantled and the area is reoccupied. S.3 Analytical Procedures All asbestos bulk -samples were analyzed by a National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratory via Polarized Light Microscopy (PLM) for asbestos content (see Appendix B for laboratory report). 6.0 Homogeneous Areas A Homogeneous Area (HA) includes materials that are uniform in appearance, color, texture and date of application. The asbestos content of the bulk -samples collected within a homogeneous area can be applied to the entire homogenous area if they conform to the above characteristics and the regulated minimum sample quantities of each type of material are collected and analyzed. 6.1 Material Friability A material can either be friable or non friable. A friable material is one that, when dry, can be pulverized, or reduced to powder by hand pressure, a non -friable material cannot. A non -friable material may become friable if its condition had deteriorated or has been impacted by forces that have rendered it friable. 6.2 Material Classifications Sampled materials are divided into one of the following three categories: • Surfacing Material: sprayed or troweled onto structural building members • Thermal System Insulation (TSI): any type of pipe, boiler, tank, or duct insulation • Miscellaneous Material: all other materials not classified in the above two categories 6.3 Material Conditions Sampled materials are placed into one of the three following categories of conditions: • Good: none to very little visible damage or deterioration Damaged: the surface is crumbling, blistered, water -stained, gouged, marred or otherwise abraded over less than one -tenth of the surface if the damage is evenly distributed, or one -quarter if the damage is localized Significantly Damaged: the surface is crumbling, blistered, water -stained, gouged, marred or otherwise abraded over greater than one -tenth of the surface if the damage is evenly distributed, or one -quarter if the damage is localized 6.4 Sample Quantities Banyan Environmental collected at least the minimum number of samples from each homogeneous area necessary to meet all regulatory requirements for the quantity of material to be disturbed. The quantities listed in this report are approximate and on -site verification of the exact quantity of each material is required. The following outlines the minimum sample quantities required per homogeneous area: • Surfacing Materials: up to 1,000 ft2 of material requires a minimum of three (3) samples; between 1,000 ft2 and 5,000 ft2 of material requires a minimum of five (5) samples; over 5,000 ft2 of material requires a minimum of seven (7) samples; one (1) sample of each patch • Thermal System Insulation (TS1): each homogeneous area requires a minimum of three (3) samples; at least one (1) sample must be collected from each patch; and collect enough samples sufficient to adequately assess the material and determine the asbestos content for TSI fittings such as pipe elbows or T's. • Miscellaneous Materials: collect enough samples sufficient to determine the asbestos content 7.0 Overview of Findings Asbestos was reported within some of the materials collected. Banyan Environmental collected a total of ten (10) asbestos bulk -samples of four (4) homogeneous areas. These areas included a smooth surfacing texture found in the main level laundry area and hall bathroom, an orange peel surfacing texture found in the main level NE bedroom and a miscellaneous 2x3 white porous ceiling tile in the main level bathroom. Table 1 below describes the materials composing each homogeneous area as well as the locations of each bulk -sample collected. Also listed is the classification, condition, friability and estimated quantity of material to be removed and/or disturbed, as well as the asbestos content within each bulk -sample. Please see Appendix B: Analytical Data for the layer break -down of each bulk -sample.

Point Count Friable materials still have to be point -counted in order to call them native (and unregulated). Therefore, any friable layer reported as -<1% must be point -counted to prove it or be assumed to be positive despite the estimate. Non -friable samples are not mandated to be point -counted by NESHAP regardless of their estimate percentage. 9.0 Asbestos Abatement & Demolition Requirements If ACM is to be removed or disturbed in a single-family residence, and the total quantity exceeds any of the regulatory trigger levels of 50 linear ft. on pipes, 32 ft2 on other surfaces, or the volume equivalent of a 55- gallon drum, a CDPHE-certified General Abatement Contractor (GAC) is required to perform the work. The regulatory trigger levels within a commercial building are 260 linear ft. on pipes, 160 ft2 on other surfaces, or the volume equivalent of a 55-gallon drum. In addition, formal notification to CDPHE prior to the abatement of ACM as well as air monitoring, visual inspections, and final air clearances by a CDPHE- certified Asbestos AMS is required. CDPHE regulations allow for the demolition of a building that contains non -friable asbestos -containing materials, such as caulking, mastic or resilient floor tiles. However, demolition must be completed without causing the non -friable ACM to be rendered friable. Burning a building with any ACM is prohibited. Operations such as sanding, cutting, crushing, grinding, pneumatic jacking, etc. of ACM are not permitted. Recycling of building materials such as concrete, metal, or wood that are bonded or contaminated with ACM, e.g. glue, caulking, or mastic is also prohibited. If any of the non -friable asbestos containing materials are to be recycled and rendered friable after demolition (i.e. crushing mastic -coated concrete), these materials must be abated of all ACM prior to shipping offsite for recycling. OSHA regulations regarding occupational exposure during demolition activities is still mandatory. OSHA 29 CFR 1926.1101 requires that workers performing construction -related activities be protected from asbestos fibers in excess of the permissible exposure limit of 0.1 f/cc of air. Contractors are must comply with applicable provisions of OSHA 29 CFR 1926.1101 during demolition and renovation activities. These OSHA provisions include, but are not limited to, PPE and respirators, personnel training, personal -exposure air monitoring, employee medical surveillance, wet removal methods, signage for regulated areas, etc. 10.0 Disclaimer & Limitations The activities outlined in this report were conducted in a manner consistent with a level of care and expertise exercised by members of the environmental consulting and industrial hygiene profession.
