Estes Park, CO 80517 The purpose of the limited inspection was to identify and sample potentially hazardous friable and non-friable ACM that has either been affected by a recent water loss and/or may be impacted by subsequent restoration 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 contractor. The following areas include:the master bedroom ceiling surfacing material, bathroom ceiling surfacing material, living room ceiling surfacing material, upstairs bedroom wall surfacing material, kitchen wall joint compound/drywall, closet wall joint compound/drywall, bathroom wallpaper, as well as bathroom shower tile and adhesive. The remaining areas within the residence, garage or any outbuilding 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 Single Family Residence 4.0 Certifications The limited asbestos inspection and bulk-sampling was conducted by Gary Farrell with SilverKey Services. Gary Farrell is a Colorado Department of Public Health and Environment (CDPHE) certified Building Inspector; having certification number 25590. 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. 3 |Page 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). SilverKey Services 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. SilverKey Services 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. SilverKey Services 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. 5.3 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. 4 |Page 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 SilverKey Services 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 (TSI): 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. Overview of Finding Asbestos was reported within some of one or more of the samples collected. Therefore, abatement of these materials will be required. SilverKey Services collected a total of (13) asbestos bulk-samples of (5) homogeneous areas. 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. 5 |Page ASBESTOS SURVEY COLLECTION DATA __________________________________________________________________________________________________________________ HOMOGENEOUS SAMPLING AREA:HA1 MATERIAL DESCRIPTION:Surfacing material, drywall COLOR:Off white, white brown PATTERN:Orange peel QUANTITY:100 sq ft, 50 sq ft, 120 sq ft, 300 sq ft CONDITION:G MATERIAL CATEGORY:SM, MM LOCATION:Master bedroom ceiling, bathroom ceiling,kitchen ceiling, living room ceiling, upstairs bedroom wall # OF SAMPLES TAKEN:5 SAMPLE ID NUMBER(S):HA1-001, HA1-002, HA1-003, HA1-004,HA1-005 RESULT:2% Chrysotile in surfacing material FRIABILITY:Friable HOMOGENEOUS SAMPLING AREA:HA2 MATERIAL DESCRIPTION:Joint compound, drywall COLOR:Off white, white, brown PATTERN:NA QUANTITY:50 sq ft, 45 sq ft CONDITION:G MATERIAL CATEGORY:MM LOCATION:Kitchen wall, closet wall # OF SAMPLES TAKEN:2 SAMPLE ID NUMBER(S):HA2-006, HA2-007 RESULT:2% Chrysotile in joint compound FRIABILITY:Friable HOMOGENEOUS SAMPLING AREA:HA3 MATERIAL DESCRIPTION:Wallpaper, mud, drywall COLOR:Off white, white, blue, brown PATTERN:Floral QUANTITY:100 sq ft CONDITION:G MATERIAL CATEGORY:MM LOCATION:Bathroom wall # OF SAMPLES TAKEN:2 SAMPLE ID NUMBER(S):HA3-008, HA3-009 RESULT:2% Chrysotile in mud FRIABILITY:Friable 6 |Page HOMOGENEOUS SAMPLING AREA:HA4 MATERIAL DESCRIPTION:Tile, grout COLOR:White PATTERN:Square QUANTITY:65 sq ft CONDITION:G MATERIAL CATEGORY:MM LOCATION:Bathroom shower # OF SAMPLES TAKEN:2 SAMPLE ID NUMBER(S):HA4-010, HA4-011 RESULT:ND FRIABILITY:Non-friable HOMOGENEOUS SAMPLING AREA:H5 MATERIAL DESCRIPTION:Adhesive COLOR:White PATTERN:NA QUANTITY:65 sq ft CONDITION:G MATERIAL CATEGORY:MM LOCATION:Bathroom shower tile # OF SAMPLES TAKEN:2 SAMPLE ID NUMBER(S):HA5-012, HA5-013 RESULT:ND FRIABILITY:Non-friable ND-Non-detect D-Damaged MM-Miscellaneous Material HA- Homogenous Area G-Good SM-Surfacing Material TR-Trace, <1%SD-Significantly Damage TSI-Thermal System Insulation It is the responsibility of the asbestos abatement company to give a scope of work for all abatement. 7 |Page 8. Findings & Recommendations ACM was identified within the following areas: the master bedroom ceiling surfacing material, bathroom ceiling surfacing material, kitchen ceiling surfacing material, living room ceiling surfacing material, upstairs bedroom wall surfacing material, kitchen wall joint compound, closet wall joint compound, as well as the bathroom wallpaper in mud that were within the scope of the limited inspection and bulk-sampling performed on June 29th 2021.; therefore,professional abatement activities are required to remove or disturb the above-reference sampled materials.ACM was not impacted or disturbed. We do not consider this a spill; SilverKey Services recommends that when ACM is removed/abated, that only a licensed asbestos abatement contractor using personnel trained in the handling of ACM be allowed to conduct such activities using appropriate methods (HEPA- filtered vacuuming, wet cleaning methods, respiratory protection, protective clothing, personnel decontamination, negative-air enclosures, air monitoring, etc.). For all spills, SilverKey Services recommends that all soft goods (carpet, pad, clothes, couches, etc.)and any ceiling and/or wall surfacing restoration activities be removed from the interior of the building as asbestos waste. SilverKey Services also advises that only hard surfaces (plastic, metal, wood, concrete, etc.) are allowed to be left in place before the final visual and final air clearance tests are completed. SilverKey Services urges that electronics and appliances (refrigerators, air conditioners, DVD players, microwaves, toasters, etc.) are removed due to the mechanical openings and working parts that make it difficult to clean thoroughly. 8.1. ASBESTOS SPILL RESPONSES Major Spill Response Protocols If ACM is significantly damaged and the total quantity exceeds the regulatory trigger levels, the area is deemed a “Major Asbestos Spill.” The area is consequently subject to the requirements in Reg. 8, Section III.T.1. – Major Asbestos Spills, as outlined below. Additional asbestos air or dust sampling should also be conducted within the remaining areas not directly impacted by the Major Asbestos Spill to determine if asbestos-containing dust/debris has spread to adjacent areas. If asbestos fibers are found within any other areas or on building contents, they should be included in the scope of professional abatement and decontamination. The following response actions must be followed per Colorado Reg. 8 when a Major Asbestos Spill occurs: •Restrict access to the area and post warning signs to prevent entry to the area by persons other than those necessary to respond to the incident. •Shut off or temporarily modify the air handling system to prevent the distribution of asbestos fibers to other areas. • Immediately contact the Division by telephone, submit a notification in compliance with subsection III.E. (Notifications) and, if in an area of public access, apply for a permit in accordance with subsection III.G. (Permits). •Be exempted from the requirements to have a certified Supervisor on-site at all times, until such time as the immediate danger has passed. Any cleanup or asbestos abatement that must occur after the immediate danger has passed shall be supervised by a person certified by the Division. 8 |Page • Using certified Supervisors and certified Workers in accordance with section II. (Certification Requirements) of this Regulation, seal all openings between the contaminated and uncontaminated areas and establish none- detect air pressure within the contaminated area in accordance with paragraph III.J. (Air Cleaning and None- detect Pressure Requirements).This is to be accomplished using polyethylene sheeting to cover areas such as doorways,windows, elevator openings, corridor entrances, grills, drains, grates, diffusers and skylights. •HEPA vacuum or steam clean all carpets, drapes, upholstery,and other non-clothing fabrics in the contaminated area, or discard these materials. • Launder or discard contaminated clothing in accordance with subsection III.R. (Waste Handling). • HEPA vacuum or wet clean all surfaces in the contaminated area. •Discard all materials in accordance with subsection III.R. (Waste Handling). •Following completion of subparagraph III.T.1.a. through III.T.1.i. above, comply with air monitoring requirements as described in subsection III.P. (Clearing Abatement Projects); air samples shall be collected aggressively as described in 40 C.F.R. Part 763, Appendix A to Subpart E (EPA 1995), except that the air stream of the leaf blower shall not be directed at any friable ACM that remains in the area and comply with any other measures deemed necessary by the Division to protect public health. Minor Spill Response If ACM is significantly damaged and the total quantity is less than the regulatory trigger levels, however, more than three square feet or three linear feet (3 ft2/3 ln/ft.), the area is deemed a “Minor Asbestos Spill.” The area is consequently subject to the requirements in Reg. 8, Section III.T.2. – Minor Asbestos Spills, as outlined below. Additional asbestos air or dust sampling should also be conducted within the remaining areas not directly impacted by the Minor Asbestos Spill to determine if asbestos-containing dust/debris has spread to adjacent areas. If asbestos fibers are found within any other areas or on building contents, they should be included in the scope of professional abatement and decontamination. The following response actions must be followed per Colorado Reg. 8 when a Minor Asbestos Spill occurs: • Restrict access to the area and post warning signs to prevent entry to the area by persons other than those necessary to respond to the incident. • Shutoffortemporarilymodifytheairhandlingsystemtopreventthedistributionofasbestosfiberstoother areas. •Using certified Supervisors and certified Workers in accordance with section II. (Certification Requirements) of this Regulation, seal all openings between the contaminated and uncontaminated areas and establish none-detect air pressure within the contaminated area in accordance with paragraph III.J. (Air Cleaning and None-detect Pressure Requirements).This is to be accomplished using polyethylene sheeting to cover areas such as doorways,windows, elevator openings, corridor entrances, grills, drains, grates, diffusers and skylights. 9 |Page • HEPA vacuum or steam clean all carpets, drapes, upholstery, and other non-clothing fabrics in the contaminated area, or discard these materials. •Launder or discard contaminated clothing in accordance with subsection III.R. (Waste Handling). •HEPA vacuum or wet clean all surfaces in the contaminated area. •Discard all materials in accordance with subsection III.R. (Waste Handling). •Following completion of subparagraph III.T.1.a. through III.T.1.i. above, comply with air monitoring requirements as described in subsection III.P. (Clearing Abatement Projects); air samples shall be collected aggressively as described in 40 C.F.R. Part 763, Appendix A to Subpart E (EPA 1995), except that the air stream of the leaf blower shall not be directed at any friable ACM that remains in the area and comply with any other measures deemed necessary by the Division to protect public health. 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.7 crushing mastic-coated concrete), these materials must be abated of all ACM prior to shipping off site for recycling. OSHA regulations regarding occupational exposure during demolition activities are 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 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 |Page 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.
