1.0 Executive Summary

SCA Environmental, Inc. (SCA) conducted a partial pre-renovation hazardous materials survey for lead-based paints, asbestos-containing construction materials, and associated environmental hazards at the Old Santa Fe Trail Building at 110 Old Santa Fe Trail in Santa Fe, CA (hereafter referred to as "the Building") on May 11, 2016.

Prior to any renovations or demolition, the National Emission Standard for Hazardous Air Pollutants (NESHAP) mandated by the Environmental Protection Agency (EPA) require that buildings be inspected for asbestos-containing materials (ACM) and materials subject to damage or which will be made friable, be removed.

Sampling by SCA in May, 2016 and Anderson Halls Architects in October 2011 found the following ACM:

Mudded elbows on the heating hot water and domestic hot water system sampled in the Basement Stairs and

Basement Storage Room and considered typical of the non-abated segments and concealed risers and branches throughout the building [SCA Sample I.D. OSFT-TSI-107-1 & 2 with 10% Chrysotile].

White interior plasters over gray base plasters with horse hair sampled in Annex Building Room A5 western perimeter façade [SCA Sample I.D. OSFT-WLPL-104-10 with 2% Chrysotile in the brown base layer] [Note the interior plasters throughout the Annex Building shall be treated as asbestos-containing].

White interior plasters over gray base plasters with horse hair sampled in Annex Building Shop A5 southern perimeter façade [SCA Sample I.D. OSFT-WLPL-104-11 with 2% Chrysotile in the brown base layer]

[Note the interior plasters throughout the Annex Building shall be treated as asbestos-containing].

Note that the thermal system insulation was abated during the boiler replacement project within the past 3 to 4 years.

However, mudded elbows and remnants of the original system are still visible in the Crawl Space Tunnels and the Basement Records and Storage Rooms as well as at concealed risers and branches on both the heating hot water system and the domestic hot water system. The extent of required abatement for the seismic renovations is unknown but could impact segments of these systems if plaster removal is required indoors.

Interior plasters throughout the Annex Building shall be treated as ACM based on the serial analyses completed for these samples.

Suspect materials that were not sampled but should be assumed to be asbestos-containing include the following:

Suspect older vinyl floor tiles and associated mastics under carpeting in various locations [SCA Sample I.D.

OSFT-FLVCT-AAA, assumed ACM].

Destructive testing may be warranted for the above suspect ACM following vacancy of the building or area to ascertain the validity of the assumptions.

“Trace” asbestos-containing materials (>0.1% and <1% asbestos by weight) sampled by SCA include:

Pink white stucco skimcoat over gray base coat and non-ACM building paper sampled on the 1 st Floor west facade [AHA Sample I.D. #1 W1 with <1% Chrysotile in the skimcoat and base stucco plasters].

Pink white stucco skimcoat over brown/gray base coat over reddish/gray stuccos with white fibrous debris sampled on the 1 st Floor south facade [AHA Sample I.D. #4 S1 with <1% Chrysotile in all layers].

Pink multi-colored stucco plaster over non-ACM building paper over pink/gray and red/gray older stucco plasters sampled on the 2 nd

Floor west facade [AHA Sample I.D. #5 W2 with <1% Chrysotile in the pink multi-colored layer].

Multi-layered exterior stucco plasters sampled at SW Annex corner with sandy tea-colored layer over older

SCA Project No.: B-12033 Page 2 orange-yellow layer [SCA Sample I.D. OSFT-STUCCO-101-1 with <1% Chrysotile in the brown layer]

[Note that a 1,000 point count of this sample found <0.1% Chrysotile].

Despite a large number of samples showing no detectable asbestos in the multi-layered exterior stucco plasters, sampling in 2011 and 2016 found ‘trace’ Chrysotile in various layers. Because the removal of this material generally requires sawing into workable segments and pulverizing the materials, airborne asbestos releases are likely to occur during these operations and SCA deems that the material must be removed under full isolation procedures in compliance with 29 CFR 1926.1101 Work Class 2 procedures. The 1,000 point count of the stucco found the asbestos content at <0.1% Chrysotile, so the materials generally can be disposed as non-hazardous waste.

Non-asbestos materials sampled and documented by SCA include:

Pink white stucco skimcoat over pink base coat sampled on the 1

Floor east facade [AHA Sample I.D. #2

E1].

2.0 Introduction

This report summarizes the results of the partial pre-renovation hazardous materials survey conducted for the Old Santa Fe Trail Building at 110 Old Santa Fe Trail in Santa Fe, NM (hereafter referred to as "the Building") on May 11, 2016. The purpose of the survey was to determine the presence of regulated and/or potentially hazardous building materials in the building, which is slated for waterproofing repairs and seismic upgrades. Materials addressed in the survey include:

Asbestos-containing materials (ACM);

Lead-based paints (LBP);

Rodent fecal matter; and

Other environmental hazards as noted.

Individuals involved in the survey, and their technical certifications, include:

3.0 Methodology

3.1 Asbestos Containing Materials

Asbestos sampling was performed in a fashion designed to minimize exposure of the surveyor or others to airborne asbestos fibers. Samples were typically removed from the substrate utilizing a knife or hollow drill bit bored through a wet sponge; the sample material was then placed into an airtight plastic vial. The vial's exterior was decontaminated with a wet sponge, and a unique sample I.D. written on the vial. The vial was then stored in a plastic bag. Sample substrates were patched with a high-temperature caulking compound, where required.

Samples of suspect materials were collected using triplicate sampling procedures. Under these procedures, the first sample is analyzed. If it tests positive for asbestos (>1%), the analysis is suspended for further samples of that material. If the first sample tests only trace positive (between 0.1 to 1%), or negative, then the second and third samples are analyzed sequentially, in order to determine the possible presence of asbestos. If all three samples test negative, the material is considered as non-asbestos. If one or more samples test "trace" positive (<1%), the material is considered to be trace positive. If one or more samples are positive for asbestos, the material is considered positive.

Certain materials, such as plasters and gypboard or sheetrock systems, are frequently non-homogeneous in content.

For such materials, multiple samples were gathered at various points in the building, with all samples analyzed to determine the possible presence of asbestos.

All asbestos samples collected were submitted to EMSL for analysis by polarized light microscopy with dispersion staining (DS/PLM). The Federal Environmental Protection Agency's (EPA) regulations specify the DS/PLM method.

3.2 Lead-Based Paints

Paint samples from typical interior and exterior surfaces were analyzed in-situ to identify the presence and extent of lead-containing paints. This included samples from exterior finishes throughout the building. Samples were analyzed using a Niton XL-700 X-Ray Fluorescence (XRF) spectrum analyzer. The XRF analyzer can measure lead contents of several layers of paint without disturbing the surfaces, thus giving immediate feedback on lead contents of paint without destructive testing. The XRF is sensitive to 0.1 milligrams per square centimeter (mg/cm

) of lead, or well below HUD guideline levels of 1.0 mg/cm of lead in paints.

XRF analysis data are reported as L-shell values. The L-shell value is the lower energy fluorescence showing the level of the surface layer that is readily disturbed and potentially made airborne, thereby posing a potential construction health hazard.

Please note that although LBP were defined against the HUD standard, OSHA's Construction Lead Standard, 29 CFR 1926.62, applies to all paints with any measured lead content, requiring dust control measures to reduce airborne and ingestion lead dust hazards.

SCA Project No.: B-12033 Page 8

4.0 Applicable Standards

4.1 Asbestos-Containing Materials

ACM is defined by EPA regulations as those substances containing greater than 1% asbestos. The New Mexico Environmental Department’s Air Quality Bureau (AQB) provides local enforcement of these regulations. Friable ACM with greater than 1% asbestos needs to be disposed of as asbestos waste.

Regulated Asbestos-Containing Materials (RACM) is defined as (a) Friable – the material can be crumbled, pulverized or reduced to powder by hand pressure, (b) Category 1 that are subjected to sanding, grinding, cutting or abrasion, (c) Category I materials that becomes friable during demolition or renovation activities, or (d) Category II materials that become friable during demolition or renovation activities.

Federal Occupational Safety and Health Administrations (OSHA) regulations, locally enforced by New Mexico OSHA, define ACM as substances that contain greater than 1% asbestos. OSHA also mandates special training, medical exams, personal protective equipment and record keeping for employees working with ACM. If a material contains less than 1% asbestos but more than 0.1% asbestos, the material may be disposed of as non-ACM, but the OSHA requirements would still have to be followed regarding workers' protection and Contractor licensing.

"Trace" materials are currently regulated in OHSA and require the following:

Removal using wet methods;

Prohibition of removal using abrasive saws or methods which would aerosolize the material, without dust collection or dust suppression systems utilized in conjunction with these means and methods; and

Prompt clean-up of the impacted zone, using HEPA-filtered vacuums, as applicable.

Further detail regarding various New Mexico asbestos regulations can be found from the following websites:

https://www.env.nm.gov/aqb/asbestos/ http://164.64.110.239/nmac/parts/title20/20.009.0008.htm for asbestos disposal requirements http://www.epa.gov/asbestos/pubs/help.html http://www.epa.gov/asbestos/pubs/asbreg.html

4.2 Lead-Based Paints

Since elemental lead is a suspect carcinogen and known teratogen and neurotoxic in high doses, lead-containing materials need to be identified prior to the on-set of demolition activities. Using combinations of engineering controls and personal protective equipment, lead-containing materials can be remediated safely. Several sources of applicable standards are listed as follows:

1. Occupational Exposure: Lead exposures in the workplace are regulated by OSHA, which has certain regulatory requirements for identifying and controlling potential lead exposures. Currently applicable regulations for the construction industry have been adopted from the Federal OSHA regulations. The current OSHA 8-hour Permissible Exposure Level (PEL) for lead is 50 µg/m

2. Lead Waste: The maximum allowable concentration of lead for non-hazardous waste disposal in New

Mexico id 5.0 mg/l per U.S. EPPA test method 1311 toxicity characteristic leaching procedures (TCLP) per New Mexico Title 20 Chapter 9, Part 8, Paragraph 16

3. Definitions & Notifications: The major definitions of LBP or lead-coated surfaces are listed as follows:

https://www.env.nm.gov/aqb/asbestos/ http://164.64.110.239/nmac/parts/title20/20.009.0008.htm http://www.epa.gov/asbestos/pubs/help.html http://www.epa.gov/asbestos/pubs/asbreg.html

SCA Project No.: B-12033 Page 9

a. HUD defines LBP as paint that contains either >0.5% by weight of lead, or >1 mg/cm2.

b. Consumer Product Safety Commission (CPSC) prohibits the manufacturing of paint that contains more than 600 ppm (0.06%) of lead.

Given the myriad of confusing definitions and regulations, this report uses the HUD's definition for the purpose of identifications, but compliance to OSHA's Construction Lead Standard is required for all paints with any measurable lead content.

4. New Renovation, Repair and Painting Rules finalized by the U.S. Environmental Protection Agency on June 23, 2008, authorized under section 402(c )(3) of the Toxic Substances Control Act (TSCA) require any Contractor or Maintenance Personnel disturbing more than 6 sq. ft. of interior or 20 sq. ft. of exterior lead-based paints (LBPs) in pre-1978 housing or child-occupied facilities to complete EPA-accredited training or 4-hr. EPA-accredited refresher training, as applicable, for lead safe work practices. Persons performing renovations, repairs and/or painting projects in target housing or child-occupied facilities must provide “Renovate Right” brochures to the Owners and occupants after December 22, 2008. Window replacements are subject to the standards. These standards prohibit certain dangerous work practices, such as open flame burning or torching of lead-based paints. Required work practices include posting of warning signs, restricting occupants from work areas, containing work areas to prevent dust and debris from spreading, conducting a thorough cleanup and verifying that the cleanup is effective. Additional rules and information are available at www.epa.gov/lead.

“Certified Renovators” shall perform the following tasks:

Perform or direct uncertified workers performing regulated renovation activities;

Provide training to uncertified workers on lead safe work practices;

Be on-site during key stages of the renovation and otherwise be available on-site or by telephone at other times;

Use an acceptable lead test kit to determine whether lead-based paints are present in an affected area.

Firms may apply for certification beginning in October 2009 and must be certified by April 2010.

5.0 Results and Conclusions

5.1 Asbestos

The detailed results are shown in the Laboratory Report in Attachment 1. Sample locations are shown on the drawings included as Attachment 4.

Sampling by SCA in May, 2016 and Anderson Halls Architects in October 2011 found the following ACM:

Mudded elbows on the heating hot water and domestic hot water system sampled in the Basement Stairs and

Basement Storage Room and considered typical of the non-abated segments and concealed risers and branches throughout the building [SCA Sample I.D. OSFT-TSI-107-1 & 2 with 10% Chrysotile].

White interior plasters over gray base plasters with horse hair sampled in Annex Building Room A5 western perimeter façade [SCA Sample I.D. OSFT-WLPL-104-10 with 2% Chrysotile in the brown base layer] [Note the interior plasters throughout the Annex Building shall be treated as asbestos-containing].

White interior plasters over gray base plasters with horse hair sampled in Annex Building Shop A5 southern perimeter façade [SCA Sample I.D. OSFT-WLPL-104-11 with 2% Chrysotile in the brown base layer]

[Note the interior plasters throughout the Annex Building shall be treated as asbestos-containing].

Note that the thermal system insulation was abated during the boiler replacement project within the past 3 to 4 years.

However, mudded elbows and remnants of the original system are still visible in the Crawl Space Tunnels and the Basement Records and Storage Rooms as well as at concealed risers and branches on both the heating hot water system and the domestic hot water system. The extent of required abatement for the seismic renovations is unknown but could impact segments of these systems if plaster removal is required indoors.

Note that heating hot water lines to the 2 nd Floor appear to run within the perimeter walls. If seismic renovations require partial demolition of the plasters within these areas, these lines may be exposed, such that abatement will be feasible. If seismic upgrades do not impact these plasters, then abatement of the TSI should generally not be necessary at this time.

Interior plasters throughout the Annex Building shall be treated as ACM based on the serial analyses completed for these samples. Interior plasters in the Main Building were all found to be non-asbestos.

Suspect materials that were not sampled but should be assumed to be asbestos-containing include the following:

Suspect older vinyl floor tiles and associated mastics under carpeting in various locations [SCA Sample I.D.

OSFT-FLVCT-AAA, assumed ACM].

Destructive testing may be warranted for the above suspect ACM following vacancy of the building or area to ascertain the validity of the assumptions.

“Trace” asbestos-containing materials (>0.1% and <1% asbestos by weight) sampled by SCA include:

Pink white stucco skimcoat over gray base coat and non-ACM building paper sampled on the 1

Floor west facade [AHA Sample I.D. #1 W1 with <1% Chrysotile in the skimcoat and base stucco plasters].

Pink white stucco skimcoat over brown/gray base coat over reddish/gray stuccos with white fibrous debris sampled on the 1 st Floor south facade [AHA Sample I.D. #4 S1 with <1% Chrysotile in all layers].

Pink multi-colored stucco plaster over non-ACM building paper over pink/gray and red/gray older stucco plasters sampled on the 2 nd

Floor west facade [AHA Sample I.D. #5 W2 with <1% Chrysotile in the pink multi-colored layer].

SCA Project No.: B-12033 Page 11

Multi-layered exterior stucco plasters sampled at SW Annex corner with sandy tea-colored layer over older orange-yellow layer [SCA Sample I.D. OSFT-STUCCO-101-1 with <1% Chrysotile in the brown layer]

[Note that a 1,000 point cont of this sample found <0.1% Chrysotile].

Despite a large number of samples showing no detectable asbestos in the multi-layered exterior stucco plasters, sampling in 2011 and 2016 found ‘trace’ Chrysotile in various layers. Because the removal of this material generally requires sawing into workable segments and pulverizing the materials, airborne asbestos releases are likely to occur during these operations and SCA deems that the material must be removed under full isolation procedures in compliance with 29 CFR 1926.1101 Work Class 2 procedures. The 1,000 point count of the stucco found the asbestos content at <0.1% Chrysotile, so the materials generally can be disposed as non-hazardous waste.

Recommended abatement procedures would include scaffolding and shrink-wrapping the exterior stucco areas throughout. This will allow for full isolation of the abatement activities and weather protection during the reconstruction phase.

5.3 Lead-Based Paints

Lead-based paints (LBP), as defined by U.S. Department of Housing and Urban Development (HUD), were identified at the site, including but not necessarily limited to the following:

Off-white paints on the stucco exterior Courtyard façade outside Room 131 [SCA Sample I.D. OW-07-3 with 1.20 mg/cm

Rust-colored paints on the Main Courtyard stucco façade at Room 123 [SCA Sample I.D. RU-09-3 with 2.4 mg/cm

Rust-colored paints on the Main Courtyard exterior stucco façade at Room 115 [SCA Sample I.D. RU-09-4

SCA Project No.: B-12033 Page 14 with 1.80 mg/cm

Pink ceramic tile glazing in the Main Building’s Men’s Toilet [SCA Sample I.D. PK-14-1 with 6.80 mg/cm

Off-white paints on the entry wall plasters in Great Room 132 [SCA Sample I.D. OW-24-1 with 3.30 mg/cm

Various colored ceramic wall tile glazing in the Men’s & Women’s Toilets throughout.

Most site paints were found to be below the HUD LBP criteria, although dust control procedures are required throughout the demolition of painted elements to comply with the OSHA regulations under 29 CFR 1926.62. All site paints shall be treated as having a lead content greater than 600 ppm requiring dust control procedures in compliance with 29 CFR 1926.62.

Loose and peeling paints should be removed under controlled procedures prior to any demolition of the structure.

None of the applicable regulations require removal of LBP prior to demolition or renovation if the paints are securely adhered to the substrates (i.e., non-flaking or non-peeling). Disposal of the demolition debris in this case can be handled as non-hazardous and non-RCRA waste after the loose and flaking paints have been removed, as long as demolition practices do not compromise worker safety.

Conventional demolition techniques should be employed for all painted surfaces with the Contractor complying with applicable OSHA statutes regarding:

Worker awareness training;

Exposure monitoring, as needed;

Medical examinations, including blood lead level testing; and

Establishing a written respiratory protection program.

5.4 Other Hazards

SCA was requested to assess the presence of fecal matter on-site from past rodent infestations. Examination of the wet walls, crawl space tunnels and the topside of wiring and piping chases found evidence of past infestations;

however, the quantity of contamination is generally modest and can be readily cleaned using a HEPA-filtered vacuum. Fecal matter and HEPA vacuum contents shall generally be disposed as sanitary waste. PPE used shall minimally include protective gloves and a N-95 dust mask during cleanup.

6.0 Limitations and Exclusions

SCA warrants that this survey was performed using due care and state of the art techniques. Beyond this, SCA does not warrant or guarantee the survey. Despite the care exercised, some materials may not have been identified, or may have been incompletely identified. This condition may occur due to renovations or original construction practices that concealed older materials, and/or visually similar materials with different compositions.

This document is not a stand-alone document; abatement of materials is recommended to be completed under the oversight and design of an AHERA-accredited Project Designer and Certified Asbestos Consultant. Although due care is exercised in the course of the survey, concealed materials may be found in the course of performing the abatement or demolition; a contingency budget should be included in any cost estimates to cover unexpected conditions.

Note that SCA’s survey was geared to the waterproofing and roofing repairs as well as identifying substrates that may be impacted by the seismic upgrades. This survey was not a complete building survey and did not investigate flooring throughout the entire site.
