Dear Mr. McDaniel:

On December 22, 2015, Terracon Consultants, Inc. (Terracon) conducted a limited asbestos-containing materials (ACM) survey and lead-containing paint (LCP) survey to establish asbestos content and lead levels present in the building materials associated with the Pump Station located at East Old Military Road in Penitas, Texas.

Asbestos was not identified in the materials sampled from the Pump Station. Please refer to the attached report for details.

Various paint coatings sampled were found to have detectable levels of lead in the paint combinations sampled. A single paint coating sampled was found to exhibit a lead content above 5,000 ppm which would be considered “Lead-Based Paint”. Please refer to the attached report for details.

1.0 INTRODUCTION

Terracon conducted a limited asbestos-containing materials (ACM) survey and lead-containing paint (LCP) survey of the Pump Station building located at East Old Military Road in Penitas, Texas. The survey was conducted on December 22, 2015, by Mr. Guadalupe Torres, a Texas Department of State Health Services (TDSHS) licensed and Environmental Protection Agency (EPA) accredited Asbestos Inspector in general accordance with our proposal dated October 22, 2015.

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 demolition activities.

Samples were delivered to a National Voluntary Laboratory Accreditation Program (NVLAP) accredited and TDSHS licensed laboratory for analysis by Polarized Light Microscopy (PLM) protocol.

The lead-containing paint sampling was intended to identify and assess the lead content of the paint/coating materials which might be disturbed in the planned renovation/demolition activities. Samples of suspect LCP were delivered to an American Industrial Hygiene Association (AIHA) accredited laboratory for analysis utilizing Atomic Absorption Spectrometry (AAS Flame) methodology.

1.1 Project Objective

We understand that this survey was requested to facilitate the potential renovation of the building currently on the site. The Texas Department of State Health Services (TDSHS) regulates asbestos-related activities in the State of Texas. The TDSHS Texas 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 building is a one-story, approximately 5,500 square foot concrete structure atop a concrete slab-on-grade foundation. The roof is a steep-sloped metal panel system. Interior walls consisted of either concrete or brick with a painted and plastered finish. The ceiling was unfinished. The floors in the building consisted of either exposed concrete or expanded metal catwalks.

3.0 FIELD ACTIVITIES

The survey was conducted and bulk material samples were obtained by Mr. Guadalupe Torres, a Texas Department of State Health Services (TDSHS) licensed and Environmental Protection Agency (EPA) accredited Asbestos Inspector employed by Terracon. A copy of the individual licenses and certificates are attached in Appendix F. 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 sampling was conducted by Mr. Guadalupe Torres, an appropriately trained Lead Inspector. A summary of 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 on the site 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 were not sampled in order to prevent excessive damage to the material. Suspect materials, such as mastic should be sampled prior to renovation activities if the activities will disturb the materials.

Terracon visually assessed interior and exterior areas of the building to identify painted/coated surfaces with suspect Lead Containing Paint (LCP). Painted/coated surfaces which appear similar throughout in terms of color, texture, substrate and date of application are treated as a homogeneous material for paint chip collection purposes. Painted/coated surfaces were visually assessed for evidence of distress, flaking, chipping and/or peeling.

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.

A physical assessment for the LCP sampling of each painted/coated surface was conducted to assess its condition. The painted/coated surfaces were assessed to be in good, fair or poor condition depending on degree of cracking, flaking, chipping and/or peeling.

3.3 Sample Collection

Based on results of the visual observation, bulk samples of suspect ACM were collected in general accordance with AHERA and TAHPA 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.

Nineteen (19) bulk samples were collected from five (5) homogeneous areas of suspect ACM.

A summary of suspect ACM samples collected during the survey is included as Appendix A.

Six (6) bulk samples of suspect paint/coating materials were collected for lead analysis. 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-containing samples collected during the survey is included as Appendix C.

3.4 Sample Analysis

Bulk samples of suspect ACM materials were submitted under chain-of-custody to Moody Labs of Farmers Branch, Texas for analysis by Polarized Light Microscopy with dispersion staining (PLM/DS) techniques per EPA’s Method for the Determination of Asbestos in Bulk Building Materials (600/R-93-116). The percentage of asbestos, where applicable, was determined by microscopical 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 B of this report.

Bulk samples of the suspect lead-containing paint materials collected during the limited survey were analyzed by Environmental Hazards Services (EHS), 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 D.

4.0 REGULATORY OVERVIEW

The State of Texas has established the Texas Asbestos Health Protection Rules (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

January 25, 2016 ■ Terracon Project No. 88157214

Responsive ■ Resourceful ■ Reliable 5 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.

Friable ACM, Category I and II non-friable ACM 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 Occupational Safety and Health Administration (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.

The State of Texas has established the Texas Environmental Lead Reduction Rules (TELRR) Texas Administrative Code (TAC), Title 25, Part 1, Chapter I, Subchapter 295 to establish the means to control and minimize public exposure to lead by regulating lead-based paint activities in target housing and child-occupied facilities. The TELRR contains procedures and requirements for the accreditation of lead training providers, procedures and requirements for the certification of individuals and firms engaged in lead-based paint activities and standards for performing such activities in target housing and child-occupied facilities. The TELRR requires that all lead-based paint activities in target housing and child-occupied facilities be performed by certified individuals.

Regulatory agencies (HUD, TDSHS) have defined LBP as a paint or other surface coating that contains equal to or greater than ≥5,000 parts per million (ppm) of lead or more than 0.5% of lead by weight for buildings that meet the definition of target housing. The Occupational Safety and Health Administration (OSHA) define LBP as a paint which contains lead, regardless of the concentration.

The OSHA Lead Standard for Construction (29 CFR 1926.62) applies to construction work where an employee may be occupationally exposed to lead. All work related to construction, January 25, 2016 ■ Terracon Project No. 88157214

Responsive ■ Resourceful ■ Reliable 6 alteration, or repair (including painting and decorating) is included. The lead-in-construction standard applies to any detectable concentration of lead in paint. 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.

As the building on the site is an industrial facility rather than Child Occupied or Target Housing, HUD and TDSHS lead regulations do not apply to removal operations within the facility. It is, however, recommended that they be consulted as a general guideline for occupant protection.

5.0 FINDINGS AND RECOMMENDATIONS

Laboratory analysis indicated no asbestos was detected in the materials sampled within the Pump Station located on the site.

It should be noted that suspect materials, other than those identified during the December 22, 2015, 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 process, those materials should be assumed asbestos-containing until sampling and analysis can confirm or deny their asbestos content.

Laboratory analytical reports related to the asbestos sampling are included in Appendix B.

Five (5) of the six (6) bulk 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.

n L-01 – The light gray on light green paint material applied to select plaster and brick walls in the building was found to contain 2,100 ppm lead. Where observed, this material was found to be in good condition.

n L-03 – The black paint material applied to the metal hand rails in the building was found to contain 420 ppm lead. Where observed, this material was found to be in good condition.

n L-04 – The black on red paint materials applied to the concrete beams in the building was found to contain 120 ppm lead. Where observed, this material was found to be in good condition.

n L-05 – The green paint material applied to the metal doors and door frames of the

n L-06 – The beige paint material applied to the concrete exterior walls of the building was found to contain 31 ppm lead. Where observed, this material was found to be in good condition.

The single remaining surface coating sampled and analyzed as part of this survey was found to contain lead in a concentration exceeding 5,000 PPM, which would be considered “Lead-Based Paint” and disturbance would likely pose a potential workforce hazard:

n L-02 – The gray on light gray on dark green paint materials applied to select brick walls in the building was found to contain 30,000 ppm lead. Where observed, this material was found to be in good condition.

In areas where the Client does not intend to renovate or demolish the facility, the lead-containing/lead-based paint materials, which will remain in the facility, should be managed in place. It is recommended that this in-place management should include such operations as stabilizing or repairing any damaged materials, protecting the remaining containing paint materials from further damage, and developing a plan to periodically monitor the condition of the lead-based/containing paint materials. Notification of the presence of the materials should also be made to employees and outside contractors so that they do not inadvertently disturb the remaining lead-containing paint materials.

In areas where the renovation/demolition project which could disturb the lead-containing/lead-based paint materials within the facility is to be conducted, it is recommended that contracting personnel who may disturb the paint materials within the facility be made aware of the lead content in the materials so that they may exercise proper OSHA procedures for personnel monitoring and possibly employ protective procedures when working with the coatings.

It is recommended if impacted by renovation or demolition activities, any painted metal building components which are to be removed from the facility be segregated from the waste stream and be transferred to a suitable metal recycling facility. As the facility is a public facility rather than Target Housing, HUD and TDSHS lead regulations do not apply to removal operations within the facility. It is, however, recommended that they be consulted as a general guideline for occupant protection and that OSHA notification be made to all employees or contractors working on any repair, renovation or demolition projects within the facility.

Compliance with applicable OSHA lead regulations is the responsibility of the contractor performing the work and it is recommended that they be required to communicate potential lead hazards to their workforce and utilize lead-safe work practices such as outlined in the

EPA Renovation, Repair, and Painting (RRP) Final Rule (40 CFR 745) or applicable portions of the Structural Steel Painting Council (SSPC) Guidelines. It is further recommended that activities such as flame/torch dismantling, dry sanding and/or dry grinding of any components with lead-containing materials applied should be prohibited as part of any repair, renovation or demolition activity.
