Re: Asbestos Survey and Lead-Containing Paint Sampling French Legation State Historic Site 802 San Marcos Street, Austin, Texas 78702 Terracon Project No. 96187376

Dear Ms. Colfax:

The purpose of this report is to present the results of an asbestos survey and lead-containing paint sampling performed on June 8, 2018, at the above referenced site in Austin, Texas. This survey was conducted in general accordance with our proposal dated May 10, 2018. We understand that this survey was requested to facilitate the planned renovations and additions to the site.

Asbestos-containing HVAC ductwork mastic materials were identified in the Attic Area of the Legation House. Please refer to the attached report for details.

Eight (8) of the paint materials sampled and analyzed as part of this survey were found to contain lead in a concentration exceeding 5,000 parts per million (ppm) which would render the material “Lead-Based”. Nine (9) of the paint materials sampled and analyzed as part of this survey were found to contain lead in a concentration exceeding the detection limit, but less than 5,000 ppm which would render the material “Lead-Containing”, and be considered a potential hazard by OSHA. Seven (7) of the paint materials sampled and analyzed as part of this survey contain levels of lead below the detection limit for the analysis run. Please refer to the attached report for details.

Terracon appreciates the opportunity to provide this service to the Texas Historical Commission. If you have any questions regarding this report, please contact the undersigned at (512) 442-1122.

ASBESTOS SURVEY AND LEAD-CONTAINING PAINT SAMPLING REPORT French Legation State Historic Site 802 San Marcos Street Austin, Texas Terracon Project No. 96187376 July 12, 2018

1.0 INTRODUCTION

Terracon conducted an asbestos survey and lead-containing paint sampling in the four (4) structures located on the French Legation State Historic Site at 802 San Marcos Street in Austin, Texas. The survey was conducted on June 8, 2018, by Mr. Robert Dyer and Mr. Michael Jenkins, State of Texas licensed Asbestos Inspectors and State of Texas certified Lead Inspectors, and Mr. Richard Ian Howes, a TDSHS licensed Asbestos Consultant and State of Texas certified Lead Inspector, employed by Terracon, in general accordance with our proposal dated May 10, 2018.

Interior and exterior building components were surveyed and homogeneous areas of suspect asbestos-containing materials (ACM) were visually identified and documented. Although reasonable effort was made to survey accessible suspect materials, additional suspect but un- sampled materials could be located in walls, in voids or in other concealed areas. Suspect ACM samples were collected in accordance with Texas Asbestos Health Protection Rules (TAHPR) and in general accordance with EPA guidance document number EPA 560 5/84-024 and were intended to identify and assess suspect materials prior to renovation/demolition activities. Samples were delivered to a National Voluntary Laboratory Accreditation Program (NVLAP) accredited and Texas Department of State Health Services (TDSHS) licensed laboratory for analysis by Polarized Light Microscopy (PLM) protocol.

The lead-containing paint sampling was conducted in general accordance with Texas Environmental Lead Reduction Rules (TELRR) and was intended to identify and assess the lead content of the materials which might be disturbed in the planned demolition activities. Samples were delivered to an American Industrial Hygiene Association (AIHA) accredited laboratory utilizing Atomic Absorption Spectrometry (AAS Flame) methodology.

1.1 Project Objective

We understand the asbestos survey and lead-containing paint sampling was requested to facilitate the planned renovation of the structures located at 802 San Marcos Street in Austin, Texas.

The TDSHS regulates asbestos-related activities in the State of Texas. The TDSHS Texas

Responsive ■ Resourceful ■ Reliable 1 Asbestos Survey and Lead Sampling Report French Legation State Historic Site ■ Austin, Texas July 12, 2018 ■ Terracon Project No. 96187376

Asbestos Health Protection Rules (TAHPR) require that a licensed Asbestos Inspector conduct an asbestos survey which conforms to generally accepted industry standards such as the protocol specified in 40 CFR Part 763.85, commonly referred to as the Asbestos Hazard Emergency Response Act (AHERA) that applies to schools. Other factors are taken into consideration when determining the best method to determine the location, extent and condition of Asbestos-Containing Materials (ACMs) in a non-school building.

EPA regulation 40 CFR 61, Subpart M, National Emission Standards for Hazardous Air Pollutants (NESHAP), prohibits the release of asbestos fibers to the atmosphere during renovation or demolition activities. The asbestos NESHAP, which is enforced by the TDSHS, requires that prior to the commencement of demolition or renovation, that the facility or part of the facility affected be thoroughly inspected for the presence of both Friable (Regulated Asbestos- Containing Building Materials), and Non-Friable (Category I & II Asbestos-Containing Materials). The Occupational Health and Safety Administration (OSHA) has promulgated a worker protection standard for the disturbance of asbestos during renovation and demolition projects.

The Department of Housing and Urban Development (HUD) guidelines consider a lead content equal to or greater than 5,000 parts per million (PPM) to be the level at which paint is considered to be “lead-based” and at which point a potential hazard exists. The Occupational Safety and Health Administration (OSHA) considers paint containing any level of lead above the analytical method detection limit a potential hazard which should be communicated to any employees or contractors who may disturb the materials in the course of their assigned work.

2.0 BUILDING DESCRIPTION

The site has been developed with four (4) structures, the Legation House, Visitor’s Center (Carriage House), Privy, and Kitchen Building. Interior walls and ceilings throughout the structures consisted of wood with select installations of drywall and wallpaper in some locations. Floors throughout the structures were finished with hardwood, select installations of ceramic and resilient floor tile and painted wood. The heating, ventilation, and air conditioning (HVAC) equipment was observed in the Attic and an air handler closet in the Legation House, Kitchen Building and Visitor’s Center. The Privy is an unconditioned space.

3.0 FIELD ACTIVITIES

The survey was conducted and bulk material samples were obtained by Mr. Robert Dyer and Mr. Michael Jenkins, State of Texas licensed Asbestos Inspectors (TDSHS License Numbers 600873 and 603194) and State of Texas certified Lead Inspectors (TDSHS License Number 2070598 and 2090034), employed by Terracon. Copies of Mr. Dyer’s and Mr. Jenkins’ licenses and certificates are attached in Appendix G. The survey was conducted in general accordance with the sample collection protocols established in the TAHPR and/or EPA regulation 40 CFR 763, the Asbestos Hazard Emergency Response Act (AHERA). The lead testing was conducted in general accordance with Texas Environmental Lead Reduction Rules (TELRR). A summary of

Responsive ■ Resourceful ■ Reliable 2 Asbestos Survey and Lead Sampling Report French Legation State Historic Site ■ Austin, Texas July 12, 2018 ■ Terracon Project No. 96187376 survey activities is provided below.

3.1 Visual Assessment

Our survey activities began with visual observation of the interior and exterior areas of the building to identify homogeneous areas of suspect ACM. A homogeneous area consists of building materials that appear similar throughout in terms of color, texture and date of application. Interior assessment was conducted throughout visually accessible areas of the building where renovations are reportedly planned. Building materials identified as concrete, glass, wood, masonry, metal or rubber were not considered suspect ACM.

Suspect materials located behind mirrors or beneath ceramic tile were sampled where possible; however, large areas were not disturbed in order to prevent excessive damage to the material. Suspect materials, such as mirror mastic or thin set, should be sampled prior to demolition or renovation activities if the activities will disturb the materials.

3.2 Physical Assessment

A physical assessment of each homogeneous area of suspect ACM was conducted to assess the friability and condition of the materials. A friable material is defined by the EPA as a material which can be crumbled, pulverized or reduced to powder by hand pressure when dry. Friability was assessed by physically touching suspect materials.

3.3 Sample Collection

Based on results of the visual observation, bulk samples of suspect ACM were collected in general accordance with AHERA and TAHPR sampling protocols. Random samples of suspect materials were collected in each homogeneous area. The sample team member collected bulk samples using wet methods as applicable to reduce the potential for fiber release. Samples were placed in sealable containers and labeled with unique sample numbers using an indelible marker.

Forty-five (45) bulk samples were collected from fifteen (15) homogeneous areas of suspect ACM. A summary of suspect ACM samples collected during the survey is included as Appendix A.

Twenty-four (24) bulk samples of paint materials were collected for lead analysis in general accordance with TELRR and HUD Guidelines. The sample team member collected a bulk sample; the sample was placed in a sealable container and labeled with a unique sample number using an indelible marker. A summary of the suspect lead-based paint samples collected during the survey is included as Appendix D.

3.4 Sample Analysis

Suspect ACM bulk samples were submitted under chain of custody to Moody Labs of Farmers Branch, Texas for analysis by Polarized Light Microscopy with dispersion staining techniques (PLM/DS) per EPA’s Method for the Determination of Asbestos in Bulk Building Materials (600/R-11605-116). The percentage of asbestos, where applicable, was determined by microscopic visual estimation. Moody Labs is accredited under the National Voluntary Laboratory Accreditation Program (NVLAP Accreditation No. 102056-0) and licensed by the TDSHS (License No. 300084). Analytical results and sample chain-of custody documentation are included in Appendix C of this report.

Bulk samples of the suspect lead-containing paint materials collected were analyzed by Environmental Hazards Services, L.L.C., an American Industrial Hygiene Association (AIHA) accredited laboratory utilizing Atomic Absorption Spectrometry (AAS Flame) methodology. Reports of laboratory analysis of the suspect lead-containing paint samples collected and sample chain-of-custody documentation are included in Appendix F.

4.0 REGULATORY OVERVIEW

The State of Texas has established the TAHPR which requires any asbestos-related activity to be performed by an individual licensed by the State of Texas, through the TDSHS. An asbestos related activity consists of the disturbance (whether intentional or unintentional), removal, encapsulation, or enclosure of asbestos, including preparations or final clearance, the performance of asbestos surveys, the development of management plans and response actions, asbestos project design, the collection or analysis of asbestos samples, monitoring for airborne asbestos, bidding for a contract for any of these activities, or any other activity required to be licensed under TAHPR.

Abatement must be performed by a State of Texas licensed asbestos abatement contractor in accordance with a project design prepared by a State of Texas licensed asbestos consultant. In addition, third party air monitoring must be conducted during the abatement activities.

The asbestos NESHAP (40 CFR Part 61 Subpart M) regulates asbestos fiber emission and asbestos waste disposal practices. It also requires the identification and classification of existing building materials prior to demolition or renovation activity. Under NESHAP, asbestos containing building materials are classified as either friable, Category I non-friable or Category II non-friable ACM. Friable materials are those that, when dry, may be crumbled, pulverized or reduced to powder by hand pressure. Category I non-friable ACM includes packing, gaskets, resilient floor coverings and asphalt roofing products containing more than 1% asbestos. Category II non-friable ACM are any materials other than Category I materials that contain more than 1% asbestos.

Responsive ■ Resourceful ■ Reliable 4 Asbestos Survey and Lead Sampling Report French Legation State Historic Site ■ Austin, Texas July 12, 2018 ■ Terracon Project No. 96187376

Friable ACM, Category I and II non-friable ACM which is in poor condition and has become friable or which will be subject to drilling, sanding, grinding, cutting, or abrading and which could be crushed or pulverized during anticipated renovation or demolition activities are considered regulated ACM (RACM). RACM must be removed prior to renovation or demolition activities.

The TAHPR and NESHAP require that written notification be submitted before beginning renovation projects which include the disturbance of any asbestos-containing material (ACM) in a building or facility, or before the demolition of a building or facility, even when no asbestos is present. This written notification must be provided to the TDSHS at least 10 working days prior to the commencement of asbestos abatement or demolition activities. Removal of RACM must be conducted by a State of Texas licensed asbestos contractor. In addition, third party air monitoring must be performed during the abatement.

The OSHA Asbestos standard for the construction industry (29 CFR 1926.1101) regulates workplace exposure to asbestos. The OSHA standard requires employee exposure to airborne asbestos fibers be maintained below 0.1 asbestos fibers per cubic centimeter of air (0.1 f/cc).

The OSHA standard classifies construction and maintenance activities which could disturb ACM and specifies work practices and precautions which employers must follow when engaging in each class of regulated work. States that administer their own federally approved state OSHA programs may require other precautions.

5.0 FINDINGS AND RECOMMENDATIONS

One (1) of the homogeneous materials sampled and analyzed as part of this survey was found to contain asbestos:

 HVAC Duct Mastic – The black mastic materials utilized on the seams of the HVAC duct insulation in the Attic of the Legation House were found to contain 5% Chrysotile asbestos. The asbestos-containing mastic materials identified were noted to be in fair condition and were assessed as being non-friable. It is estimated that there exists approximately 50 square feet of these materials on the approximately 90 linear feet of ductwork present in the Attic area.

None of the other suspect building materials sampled and analyzed were found to

Responsive ■ Resourceful ■ Reliable 5 Asbestos Survey and Lead Sampling Report French Legation State Historic Site ■ Austin, Texas July 12, 2018 ■ Terracon Project No. 96187376 contain asbestos.

It should be noted that suspect materials, other than those identified during the June 8, 2018, survey may exist within the building. Should suspect materials other than those which were identified during this survey be uncovered prior to or during the renovation or demolition process, those materials should be assumed asbestos-containing until sampling and analysis can confirm or deny their asbestos content.

A summary of the classification, condition and approximate quantity of confirmed ACM are presented in Appendix B. Laboratory analytical reports are included in Appendix C.

If the Client does not intend to renovate or remove the asbestos-containing HVAC duct mastic materials present in the Legation House Attic, the asbestos-containing materials associated with the building should be managed in place. This in-place management should include such operations as repairing any damaged materials, protecting the remaining asbestos-containing materials from further damage, and developing a plan to periodically monitor the condition of the asbestos-containing materials. Notification of the presence of the materials should also be made to residents, employees and outside contractors so that they do not inadvertently disturb the remaining asbestos-containing materials.

As it is understood renovation operations which will disturb the asbestos-containing HVAC duct mastic materials present in the Legation House Attic are planned, it is recommended that the asbestos-containing materials be removed prior to conducting any other renovation. The TDSHS TAHPR require that any removal of asbestos-containing materials associated with the structure be conducted by trained and licensed asbestos abatement personnel.

According to TDSHS TAHPR, a removal project involving the removal of less than 160 square feet or 260 linear feet of asbestos-containing materials such as this would not need to be designed by a licensed Individual Asbestos Consultant. Air monitoring by a licensed third-party Air Monitor would be required during the actual removal work regardless of the size of the project. Terracon would be pleased to provide a proposal to provide these services.

It is important to note the TAHPR and NESHAP require that written notification be submitted before beginning renovation projects which include the disturbance of any asbestos-containing material (ACM) in a building or facility, or before the demolition of a building or facility, even when no asbestos is present. This written notification must be provided to the TDSHS at least 10 working days prior to the commencement of asbestos abatement or demolition activities. These activities must be performed in accordance with the current TDSHS, EPA, and OSHA guidelines.

Eight (8) of the paint materials sampled and analyzed as part of this survey were found to contain lead in a concentration exceeding 5,000 ppm which would render the material
