5 EXECUTIVE SUMMARY At the request of Prosperity Bank, RSB has performed a (ESA) of the property located at 2521 N Durham Drive in Houston, Texas, herein referred to as the Subject Property. The main objective of this ESA was to identify recognized environmental conditions in connection with the Subject Property, defined in ASTM Practice E as the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: 1) due to any release to the environment, 2) under conditions indicative of a release to the environment, or 3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not recognized environmental conditions. This ESA also includes a preliminary evaluation of certain potential environmental conditions that are outside the scope of ASTM Practice E The Subject Property includes one irregular-shaped parcel, cumulatively totaling approximately 0.20 acres. The Subject Property is currently improved with a one-story, office building and two metal sheds for nursery, with a net rentable area of approximately 720± square feet. There is no basement present beneath the existing structure. The existing improvements were reportedly constructed in At the time of assessment, the Subject Property was previously occupied by a nursery. The nursery was not in operation at the time of assessment. No manufacturing processes are currently conducted at the Subject Property. Below is the Assessment Summary Table presenting our recommended actions for the Subject Property. RSB s Findings and Opinions are presented in Section 8.0, and recommendations for further action or investigation are presented in Section 9.0. RSB Environmental 1

7 1.0 INTRODUCTION This report documents the findings, opinions, and conclusions of a Phase I Environmental Site Assessment (ESA) of the property located at 2521 N Durham Drive in Houston, TX. 1.1 PURPOSE The purpose of this ESA was to identify recognized environmental conditions and certain environmental conditions outside the scope of ASTM Practice E in connection with the property at the time of the property reconnaissance. 1.2 SCOPE-OF-SERVICES This ESA was conducted utilizing a standard of good commercial and customary practice that was consistent with the ASTM Practice E Any significant scope-of-work additions, deletions or deviations to ASTM Practice E are noted below or in the corresponding sections of this report. The scope-of-work for this assessment included an evaluation of the following: Physical characteristics of the Subject Property through a review of referenced sources for topographic, geologic, soils and hydrologic data. Subject Property history through a review of referenced sources such as land deeds, fire insurance maps, city directories, aerial photographs, prior reports, and interviews. Current Subject Property conditions, including observations and interviews regarding the following: the presence or absence of hazardous substances or petroleum products; generation, treatment, storage, or disposal of hazardous, regulated, or biomedical waste; equipment that utilizes oils which potentially contain PCBs; and storage tanks (aboveground and underground). Usage of surrounding area properties and the likelihood for releases of hazardous substances and petroleum products (if known and/or suspected) to migrate onto the Subject Property. Information in referenced environmental agency databases and local environmental records, within specified minimum search distances. Past ownership through a review of available prior reports and local municipal file review. The scope-of-work also included consideration of the following potential environmental conditions that are outside the scope of ASTM Practice E : vapor encroachment assessment, environmental compliance audit, asbestos-containing materials (ACM), lead-based paint (LBP), lead in drinking water, radon, mold, and wetlands.

8 1.3 ASSUMPTIONS, LIMITATIONS AND EXCEPTIONS This (the report) has been prepared for the use of Prosperity Bank, in accordance with our Standard Conditions for Engagement and Authorization Letter and Agreement for Environmental Services approved and signed by Melinda Faust, and with the limitations described below, all of which are integral parts of this report. A copy of the signed Standard Conditions For Engagement and Authorization Letter and Agreement for Environmental Services is maintained at the RSB Environmental office in Houston, Texas. RSB has performed this in conformance with the scope and limitations of ASTM Standard E , Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process. This report was prepared with no exceptions or deletions from ASTM Standard E This has been prepared to assess a parcel of commercial real estate with respect to the range of contaminants within the scope of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) (42 U.S.C. 9601) and petroleum products. As such, this practice is intended to permit Prosperity Bank to satisfy one of the requirements to qualify for the innocent landowner, contiguous property owner, or bona fide prospective purchaser limitations on CERCLA liability: that is, the practices that constitute all appropriate inquiry into the previous ownership and uses of the Subject Property consistent with good commercial or customary practice as defined in 42 U.S.C. 9601(35)(B). In defining a standard of good commercial and customary practice for conducting an environmental site assessment of a parcel of property, the goal of the processes established by this practice is to identify recognized environmental conditions. The term recognized environmental conditions means the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: 1) due to any release to the environment, 2) under conditions indicative of a release to the environment, or 3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not recognized environmental conditions. The term includes hazardous substances or petroleum products even under conditions in compliance with laws. The term is not intended to include de minimis conditions that generally do not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. Conditions determined to be de minimis are not recognized environmental conditions. The information reported was obtained through sources deemed reasonably ascertainable, as defined in ASTM Standard E ; a visual site survey of areas readily observable, easily accessible or made accessible by the Subject Property contact and interviews with owners, agents, occupants, or other appropriate persons involved with the Subject Property. Municipal information was obtained through review of reasonably ascertainable standard government record sources and interviews with the authorities having jurisdiction over the Subject Property. Findings, conclusions, and recommendations included in the report are based on our visual observations in the field, the municipal information reasonably obtained, information provided by the Client, and/or a review of readily available and supplied documents and drawings. RSB relies completely on the information, whether written, graphic, or verbal, provided by the Subject Property contact or as shown on any documents reviewed or received from the Subject Property contact, owner or agent, or municipal source, and assumes that information to be true and correct. Although there may have been some degree of overlap in the information provided by these various sources, RSB did not attempt to independently verify the RSB Environmental 4

9 accuracy or completeness of all information reviewed or received during the course of these environmental services. The observations in this report are valid on the date of the investigation. Where access to portions of the Subject Property or to structures on the Subject Property was unavailable or limited, RSB renders no opinion as to the presence of hazardous substances or petroleum products in that portion of the Subject Property or structure. Inaccessible portions of the Subject Property are described below. In addition, RSB renders no opinion as to the presence of, or indirect evidence relating to, hazardous substances or petroleum products where direct observation of the interior walls, floor, or ceiling of a structure was obstructed by objects or coverings on or over these surfaces. It is acknowledged that RSB judgments shall not be based on scientific or technical tests or procedures beyond the scope of the Services or beyond the time and budgetary constraints imposed by the Client. It is acknowledged further that RSB conclusions shall not rest on pure science but on such considerations as economic feasibility and available alternatives. Client also acknowledges that, because geologic and soil formations are inherently random, variable, and indeterminate in nature, the Services and opinions provided under this Agreement with respect to such Services are not guaranteed to be a representation of actual conditions on the Subject Property, which are also subject to change with time as a result of natural or man-made processes, including water permeation. In performing the Services, RSB shall use that degree of care and skill ordinarily exercised by environmental consultants or engineers performing similar services in the same or similar locality. The standard of care shall be determined solely at the time the Services are rendered and not according to standards utilized at a later date. The Services shall be rendered without any other warranty, expressed or implied, including, without limitation, the warranty of merchantability and the warranty of fitness for a particular purpose. The ASTM Standard E does not encompass analytical testing to evaluate asbestos containing materials, radon, lead-based paint, drinking water quality, indoor air quality, stored chemicals, debris, fill materials, surface water, or subsurface samples (soil and groundwater) as part of a Phase I ESA. Any analytical testing performed at the Subject Property has been conducted in accordance with the Standard Conditions for Engagement and Authorization Letter and Agreement for Environmental Services and the client-specific Scope of Work. Unless otherwise specified herein, such testing involves screening methods intended to provide a broad and approximate evaluation of conditions at readily accessible portions of the Subject Property, limited by project constraints, and should not be construed as a comprehensive program designed to comply with a specific regulatory program. If a thorough and regulatory-compliant study is warranted based on the findings of the Phase I ESA, RSB will recommend the appropriate further investigation. In certain cases, quantitative laboratory testing is performed as part of the assessment and analyses have been conducted by an outside laboratory. RSB relies upon the data provided by the outside laboratory, and has not conducted an independent evaluation of the reliability of this data. The assessment was conducted in a manner consistent with the level of care and skill ordinarily exercised by members of the profession, and in accordance with generally accepted practices of other consultants currently practicing in the same locality under similar conditions. No other representation, expressed or implied, and no warranty or guarantee is included or intended. The report speaks only as of its date, in the absence of a specific written update of the report, signed and delivered by RSB. RSB Environmental 5

14 4.1 STANDARD ENVIRONMENTAL RECORDS 4.0 RECORDS REVIEW A review of standard environmental databases maintained by Federal and state offices was completed through Environmental Risk Information Services (ERIS). The databases were searched for properties with reported environmental conditions located within approximate minimum search distances as specified by ASTM Standard E , by using geocoding information that identified the coordinates of the properties in the databases or by checking the street addresses of practically reviewable nongeocoded orphan properties within the same zip code. The database report is presented in Appendix E. The database report identified one (1) any orphan sites. Orphan sites are those sites that could not be accurately mapped or geocoded due to inadequate location information. It should be noted that plotted locations of listed sites are not always accurate. With regard to listings that are determined or suspected to be inaccurate, based on information from other sources such as direct observation or consultation with individuals familiar with the property, RSB uses the best available data when evaluating the location of listed sites discussed below. The following table provides a summary of the findings of the environmental database report. Specific properties identified within the database report are further discussed below.

15 4.1.1 Federal Agency Database Records National Priority List (NPL) The NPL database, also known as the Superfund List, is a subset of CERCLIS and identifies sites that are ranked as high priority for remedial action under the Federal Superfund Act. Neither the Subject Property nor any sites located within 1.0 mile of the Subject Property were identified on the NPL. Delisted National Priority List (NPL) The National Oil and Hazardous Substances Pollution Contingency Plan (NCP) establishes criteria that the EPA uses to delete sites from the NPL. In accordance with 40 CFR (e), sites may be deleted from the NPL where no further response is appropriate. Neither the Subject Property nor any sites located within 0.5 mile of the Subject Property were identified on the Delisted NPL database. Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS) CERCLIS contains data regarding potentially hazardous waste sites that have been reported to the USEPA by states, municipalities, private companies, and private persons, pursuant to Section 103 of the Comprehensive Environmental Response, Compensation and Liability ACT (CERCLA). CERCLIS contains sites that are included on the National Priority List (NPL), as well as sites which are in the screening and assessment phase for possible inclusion on the NPL. Neither the Subject Property nor any sites located within 0.5 mile of the Subject Property were identified on the CERCLIS database. CERCLIS No Further Remedial Action Planned (CERCLIS-NFRAP) As of February 1995, CERCLIS sites designated as No Further Remedial Action Planned (NFRAP) have been removed from the CERCLIS list. NFRAP sites may be sites where, following an initial investigation, no contamination was found, contamination was removed without the need for the site to be placed on the NPL, or the contamination was not considered sufficient to warrant Federal Superfund action or NPL consideration. Neither the Subject Property nor any sites located within 0.5 mile of the Subject Property were identified on the CERCLIS-NFRAP database Resource Conservation and Recovery Act (RCRA) Corrective Action Tracking System (CORRACTS) RCRA Info is EPA s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of RCRA Info replaces the data recording and reporting abilities of the Resource Conservation and Recovery Information System (RCRIS). The database includes selective information regarding sites that generate, transport, store, treat, and/or dispose of hazardous waste as defined by RCRA. The RCRA-CORRACTS database identifies TSD facilities that have conducted, or are currently conducting, corrective action(s) as regulated under RCRA. Neither the Subject Property nor any sites located within 1.0 mile of the Subject Property were identified on the RCRA CORRACTS database. RCRA non-corracts Treatment, Storage and/or Disposal (TSD) Facilities RCRA non-corracts Treatment, Storage and/or Disposal (TSD) facilities are required to register hazardous waste activity under the Resource Conservation and Recovery Act (RCRA). Neither the Subject Property nor any sites located within 0.5 mile of the Subject Property were identified on the RCRA non-corracts TSD database RCRA Hazardous Waste Generators RSB Environmental 11

16 Hazardous waste generators tracked under the Resource Conservation and Recovery Act (RCRA) are classified as either Large Quantity Generators (LQGs), Small Quantity Generators (SQGs), or Conditionally Exempt Small Quantity Generators (CESQG). A RCRA-LQG is defined as a facility that generates over 1,000 kilograms (Kg) of hazardous waste, or over 1 Kg of acutely hazardous waste per month. A RCRA-SQG is defined as a facility that generates between 100 Kg and 1,000 Kg of hazardous waste per month. A RCRA-CESQG is defined as a facility that generates less than 100 Kg of hazardous waste, or less than 1 Kg of acutely hazardous waste per month. Neither the Subject Property nor any adjoining properties were identified on the RCRA Generator database. RCRA non-hazardous Waste Generators RCRA Info is EPA s comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of RCRA Info replaces the data recording and reporting abilities of Resource Conservation and Recovery Information System (RCRIS) and Biennial Reporting System (BRS). A hazardous waste generator is any person or site whose processes and actions create hazardous waste. Non-generators do not presently generate hazardous waste. The Subject Property was not identified on the RCRA non-hazardous Waste Generator database. However, five (5) site located within 0.5 mile of the Subject Property was identified on the RCRA non-hazardous Waste Generators database. Four (4) of listed sites are located downgradient to the Subject Property. Based on absence of reported violation and presumed hydrogeologic gradient relative to the Subject Property, it is considered unlikely that listed facilities represent an environmental concern to the Subject Property. Information regarding remaining one (1) site is listed below: RCRA NON-HAZARDOUS WASTE GENERATORS Distance / Site Direction / Gradient* EPA ID No. Regulatory Status Fin-Tech 630 W 27 th St. Houston, TX 0.20 miles / East-northeast / Downgradient TXD Compliance Evaluation Inspection On-site * Presumed hydrogeologic gradient based upon regional topography Based upon the absence of open violations, and presumed hydrogeologic gradient relative to the Subject Property, it is considered unlikely that conditions associated with the identified RCRA non-hazardous Waste Generator facility represent an environmental concern to the Subject Property. Federal Engineering Control / Institutional Control Registries The completion of site cleanup activities may include the implementation of engineering controls or institutional controls as part of the response action. Engineering controls include various forms of caps, building foundations, liners, and treatment methods to create pathway elimination for regulated substances to enter environmental media or effect human health. Institutional controls include administrative measures, such as groundwater use restrictions, construction restrictions, property use restrictions, and post remediation care requirements intended to prevent exposure to contaminants remaining on site. Deed restrictions are generally required as part of the institutional controls. Neither the Subject Property nor any sites located within 0.5 mile of the Subject Property were identified on Federal Engineering Control or Institutional Control Registries. Emergency Response Notification System (ERNS) ERNS is a national database used to collect information regarding reported releases of petroleum products and/or hazardous substances. The database contains information from spill reports submitted to Federal agencies, including the EPA, the U.S. Coast Guard, the National Response Center, and the RSB Environmental 12

17 U.S. Department of Transportation. A review of this database was conducted in order to determine whether any spills or incidents involving releases of hazardous substances or petroleum products have occurred at the Subject Property. The Subject Property was not identified on the ERNS database State Agency Database Records State equivalent NPL Sites and CERCLIS Sites State equivalent NPL and CERCLIS databases were searched for sites located within 1.0 mile and 0.5 mile of the Subject Property, respectively. Neither the Subject Property nor any sites located within the specified minimum search distances were identified on state databases. State Spills Sites (Spills) A review of available Spills databases was conducted in order to determine whether any spills or incidents involving releases of hazardous substances or petroleum products have occurred at the Subject Property. The Subject Property was not identified on the Spills database. State Landfill Sites and Solid Waste Disposal Sites The state landfill and solid waste disposal site databases identify active or inactive landfill and transfer station facilities, as well as open dumps that failed to meet RCRA Subtitle D Section 4004 criteria for solid waste landfills or disposal sites. Neither the Subject Property nor any sites located within 0.5 mile of the Subject Property were identified on state landfill and solid waste disposal site databases. State Industrial Hazardous & Solid Waste Management Facilities List of active, inactive, and post-closure Industrial Solid and Hazardous Waste Facilities permitted by or registered with the Texas Commission on Environmental Quality (TCEQ) under the Texas Administrative Code (TAC) Title 30 Chapter 335. The Subject Property was not identified on state Industrial Hazardous & Solid Waste Management Facilities databases. However, eight (8) sites located within 0.5 mile of the Subject Property were identified on state Industrial Hazardous & Solid Waste Management Facilities database. According to the state Industrial Hazardous & Solid Waste Management Facilities database, eight (8) IHW sites are located within 0.5 mile of the Subject Property. Of the listed sites, seven (7) sites are located downgradient from the Subject Property. Based upon the distance from the Subject Property, these 7 sites are considered unlikely to represent an existing release, past release, or material threat of release of hazardous substances or petroleum products on the Subject Property. Information regarding rest one (1) IHW site is presented in the following table: STATE AND STATE INDUSTRIAL HAZARDOUS & SOLID WASTE MANAGEMENT FACILITIES Distance / Site Direction / ID No. Facility Status Gradient Walter Scott 927 W 25 th St. Houston, TX 0.25 miles / West-southwest / Upgradient Facility Status: Inactive No Reported Violations * Presumed hydrogeologic gradient based upon regional topography Based upon the absence of reported violations and facility status, it is considered unlikely that conditions associated with the identified sites represent an environmental concern to the Subject Property. State Leaking Storage Tank Sites RSB Environmental 13

18 Leaking Storage Tank Sites are properties where releases of hazardous substances or petroleum products from underground storage tanks (USTs) and/or aboveground storage tanks (ASTs) have been identified and reported to state or local agencies. The Subject Property was not identified on state Leaking Storage Tank databases. However, eight (8) sites located within 0.5 mile of the Subject Property were identified on state Leaking Storage Tank databases. All the listed eight (8) sites are located downgradient from the Subject Property. Based upon the current regulatory status and presumed hydrogeologic gradient relative to the Subject Property, it is considered unlikely that conditions associated with the identified Leaking Storage Tank sites represent an environmental concern to the Subject Property. State Registered Storage Tanks Neither the Subject Property nor any adjoining properties were identified on state Registered Storage Tank databases. State Engineering Control / Institutional Control Registries The completion of site cleanup activities may include the implementation of engineering controls or institutional controls as part of the response action. Engineering controls include various forms of caps, building foundations, liners, and treatment methods to create pathway elimination for regulated substances to enter environmental media or effect human health. Institutional controls include administrative measures, such as groundwater use restrictions, construction restrictions, property use restrictions, and post remediation care requirements intended to prevent exposure to contaminants remaining on site. Deed restrictions are generally required as part of the institutional controls. Neither the Subject Property nor any sites located within 0.5 mile of the Subject Property were identified on state Engineering Control or Institutional Control Registries. State Voluntary Cleanup Sites The Subject Property was not identified on state Voluntary Cleanup Site databases. However, one (1) sites located within 0.5 mile of the Subject Property was identified on state Voluntary Cleanup Site databases. Information regarding the listed site is presented in the following table: Site Block W 25 th St Houston, TX * Presumed hydrogeologic gradient based upon regional topography STATE VOLUNTARY CLEANUP SITES Distance / Direction / ID No. Regulatory Status Gradient 0.39 miles / TXD VCP Received: 06/14/2013 East / Contaminants: VOCS, Metals, Chlorinated Downgradient Solvents, TPH Media Affected: Soils/Groundwater Phase : Investigation/Tier 2 Based upon the distance/presumed hydrogeologic gradient relative to the Subject Property, it is considered unlikely that conditions associated with the identified Voluntary Cleanup Site represent an environmental concern to the Subject Property. State Brownfield Sites Neither the Subject Property nor any sites located within 0.5 mile of the Subject Property were identified on state Brownfield Sites databases Local Regulatory Agency Records RSB Environmental 14

19 Local municipal offices consulted during the completion of this assessment included the following: Building Department and Fire Department. RSB has submitted a written request to City of Houston above mentioned departments for information regarding the generation, transportation, storage, treatment, disposal, and/or spills or releases of hazardous substances or petroleum products at the Subject Property, in accordance with the Freedom of Information Act (FOIA). As of the date of this report, RSB has not received a response to this inquiry. Upon receipt of the agency response, if the provided information has a material affect on the findings of this report, RSB will forward this information as an addendum to this report. If no response is received, or no material information is identified, our report will not be modified. 4.2 PHYSICAL SETTING Topography The Subject Property is located at an elevation of approximately 66 feet above mean sea level (msl). The topography of the Subject Property is relatively flat and slopes gently to the west-southwest Geology and Soils No bedrock outcroppings were observed at the Subject Property. Near-surface geology in heavily developed areas such as the Subject Property and vicinity is considered urban land and is characterized by a non-homogeneous distribution of soil and fill types. Excavation and backfilling for building foundations, utility conduits, subway systems and other construction results in a varied subsurface profile. In this setting, estimation of local subsurface parameters such as permeability, moisture content, and organic fraction is not feasible without site-specific testing data. According to the Natural Resources Conservation Service (NRCS) Web Soil Survey (WSS) website ( the dominant soil composition in the vicinity of the Subject Property is classified as Aris-Urban land complex. It is classified from loamy fluviomarine deposits of late Pleistocene age. Natural drainage class is poorly drained Hydrogeology and Hydrology No natural surface water bodies were identified on the Subject Property. The nearest downgradient surface water body is the Whiteoak Bayou, located approximately 0.5 mile to the west-southwest of the Subject Property. Local groundwater gradient is expected to follow surface topography; therefore, groundwater flow near the Subject Property is expected to flow to the west-southwest. Groundwater depths and flow gradients are best evaluated by a subsurface investigation involving the installation of at least three groundwater monitoring wells and precise measurements of hydrostatic pressure. No active Monitoring wells were observed on the Subject Property Flood Zone The Federal Emergency Management Agency (FEMA) maps and rates flood hazard zones throughout the United States. These zones are depicted on a Flood Insurance Rate Map (FIRM), designated by Community Map and Panel numbers. The flood hazard zones range from Zone A or AE (A1 A130), with Base Flood Elevations (BFE) determined, to Zone X, unshaded areas outside the 500-year floodplain. RSB utilizes CDYS RiskMeter (Transamerica Data) First American Flood Data Services Flood Insights mapping system to obtain the Flood Zone Determination of the Subject Property.

28 7.0 CONDITIONS OUTSIDE THE SCOPE OF ASTM PRACTICE E The following sections address environmental issues or conditions at the Subject Property that parties may wish to assess in connection with commercial real estate that are outside the scope of ASTM Practice E (non-scope considerations). 7.1 ASBESTOS-CONTAINING MATERIAL (ACM) Asbestos is a term used to describe a group of six naturally occurring crystalline fiber minerals. Asbestos has excellent thermal stability, a high degree of tensile strength, and has been used extensively in the textile, insulation, and building industries, particularly as a component in fireproofing, decorative coatings, insulation materials, and as reinforcement for plaster binders in building products. Asbestoscontaining building materials are generally classified as friable or non-friable. Friable materials are those which can be crumbled, pulverized, or reduced to powder by hand pressure, or by normal use or maintenance can be expected to emit asbestos fibers into the air. Non-friable ACM is a potential concern if it is damaged by maintenance work, demolition, or other activities, at which time it may be considered friable. Survey for the presence of ACM was not scope of this assessment. RSB conducted a limited visual screening survey for the presence of ACM at the Subject Property. RSB identified non-friable suspect ACM in the form of sheet vinyl flooring and various construction mastics and caulking. These materials were observed to be undamaged and in good condition at the time of assessment. Please note that this survey was limited to visual observations of accessible areas and that the scope of work for this assessment did not include the collection and laboratory analysis of bulk samples of undamaged suspect ACM. Additional suspect ACM may be present in inaccessible areas, including, but not limited to, roofs, pipe chases behind solid walls and ceilings, concealed floor coverings, the interior of machinery or equipment, or water and sewer systems. It should be noted that the limited visual screening survey conducted under the scope of work for this assessment does not constitute a full asbestos inspection, in which all areas of the buildings would have been thoroughly surveyed and sampled. The possibility exists for ACM to be present in areas of the buildings not accessed or sampled by RSB personnel. Based on the limited scope of this assessment, additional suspect ACM may also present in areas of the buildings that were accessed as part of this assessment. Due to the continued distribution of a wide variety of asbestos-containing building materials, asbestos may be present in some of the roofing, flooring, wall and ceiling materials, caulking/putties, adhesives, spackling compounds, and insulation materials, as well as other building materials that may be used at the Subject Property. Sampling many of these materials requires techniques that may be destructive to subject facilities, and in the case of roofing material, may void warranties. It is recommended that an asbestos inspection be performed in accordance with all applicable federal, state, and local regulatory requirements prior to renovation, demolition, or other activities that could cause a material disturbance. Any removal or disturbance of ACM or suspect ACM should be performed by properly trained personnel and in compliance with federal, state, and local regulations. Due to the age of the Subject Property building, there is potential that ACMs are present. However, all observed suspect ACMs at the Subject Property were in good condition at the time of the site reconnaissance. Based on non-residential use of the existing buildings and in accordance with the scope of work of this assessment. ACM is not environmental concern. RSB Environmental 24

29 7.2 RADON Radon is a naturally-occurring, colorless and odorless radioactive gas that is generated primarily in granitic rocks. The United States Surgeon General has published information that radon is a cause of lung cancer. Radon usually enters a building through openings in the foundation, and therefore is a potential health concern to residents of the lowest level of a building with inadequate ventilation. The EPA Map of Radon Zones indicates that Harris County is located within a Zone 3 radon area. Zone 3 is defined as an area that has a low potential for radon gas, with a predicted average indoor radon screening level less than 2.0 picocuries per liter (pci/l). The EPA recommended Action Level for radon is 4.0 pci/l. Based upon the non-residential nature of the Subject Property and in accordance with the scope of work for this assessment, RSB did not conduct a limited short-term radon screening at the Subject Property. 7.3 LEAD-BASED PAINT (LBP) Use of lead in household paint was banned by the U.S. Environmental Protection Agency (EPA) effective January 1, The EPA and the U.S. Department of Housing and Urban Development (HUD) consider lead-based paint as containing a lead concentration equal to or greater than 1.0 milligram per square centimeter (mg/cm²) or 0.5% lead by weight, as defined by Title X of the 1992 Housing and Community Development Act. Due to the date of construction (pre-1978), LBP may be present. All painted surfaces were observed to be in good condition with no chalking, peeling or flaking. Since the property is used for non-residential use of the existing buildings and in accordance with the scope of work of this assessment, a lead-based paint (LBP) is not environmental concern. 7.4 LEAD IN DRINKING WATER Lead has historically been used in pipes, solder, and brass fixtures used in water distribution systems and building plumbing systems. In 1986, EPA banned the use of lead at concentrations exceeding 0.2% lead in solder and 8% lead in other plumbing materials. Lead in drinking water results primarily from corrosion of lead containing materials in service lines or from corrosion of lead containing materials in building plumbing systems such as lead solder, brass, bronze, and other lead containing alloys. The EPA Action Level for lead in public drinking water supplies is parts per million (ppm) or milligrams per liter (mg /L). Municipal water service is provided to the Subject Property by City of Houston. Based upon information provided by EPA web site ( the municipal water supply meets all current criteria and standards established by the Safe Drinking Water Act (SDWA), including those for lead. Based upon the existing municipal water service and in accordance with the scope of work for this assessment, RSB did not conduct lead-in-drinking water sampling at the Subject Property. 7.5 VAPOR MIGRATION RSB conducted a vapor migration screening survey of the Subject Property. RSB s site observations and review of the environmental database report (cited in Section 4.1) did not identify any conditions on the Subject Property or on adjoining properties that would indicate a REC relative to vapor migration exists at the Subject Property. RSB Environmental 25

30 This vapor migration screening was conducted in accordance with ASTM E and is not intended to satisfy the requirements of ASTM E The scope of this screening was limited to visual observations of review of the environmental database report and did not include the collection and laboratory analysis of air samples to confirm the presence of airborne contaminants by vapor intrusion. 7.6 LIMITED MICROBIAL SURVEY Microbial growth (e.g., mold or fungus) on building materials may occur when excess moisture is present. Porous building materials such as gypsum board, insulation in walls and ceilings, and carpeting retain moisture and become microbial growth sites if moisture sources are not controlled or mitigated. Potential sources of moisture include rainwater intrusion, groundwater intrusion, condensation on cold surfaces, and water leaks from building systems (e.g., plumbing leaks, HVAC system leaks, overflowing drains, etc.). Inadequate ventilation of clothes dryers and shower stalls may also result in excess moisture conditions. Microbial growth may be clearly visible (e.g., ceramic tile mortar in shower stalls) or may be concealed with no visible evidence of its existence (e.g., inside wall cavities). Interior areas of the Subject Property buildings to which access was provided and in which building elements were readily observable were inspected for the presence of moisture and visible or olfactory evidence of microbial development. No disassembly of systems or building components or physical or invasive testing was performed. No observations were conducted within concealed locations (construction elements behind wall and ceiling finishes, and other building components, etc.). The scope of this assessment was limited to visual observations of accessible areas for microbial growth and water damaged materials and did not include the collection and laboratory analysis of bulk samples or air samples to confirm the presence of microbial elements. In addition to our observation efforts, a questionnaire provided to Subject Property personnel did not indicate the presence of mold, and Subject Property personnel were not aware of the presence of moisture or mold activity. Representative observations revealed no obvious visual or olfactory indications of the presence of active moisture or mold activity at the Subject Property. Based on the interviews and conditions as observed at the time of assessment, mold does not appear to be a concern at the Subject Property. 7.6 WETLANDS RSB reviewed available information regarding wetlands on the Subject Property, including National Wetlands Inventory online GIS mapping. RSB additionally made general site observations for readily observable potential wetland characteristics. In general, to be considered a wetland, an area must have hydrophytic vegetation, evidence of wetland hydrology, and hydric soils. Review of the U.S. Department of the Interior, Fish & Wildlife Service s National Wetland Inventory (NWI) Map (available online at indicated that the Subject Property is not located on or adjacent to a wetlands area. Additionally, RSB did not observe surface water bodies, marshy areas, hydrophytic evidence of potential wetlands vegetation (aquatic plants), hydric soils, or other visible indications of potential wetland areas on or adjacent to the Subject Property. It should be noted that a detailed wetland study or wetland delineation was not included within the scope of this assessment Note that information regarding wetlands and/or open waters on the Subject Property was determined using available mapping and documentation, and does not substitute for a detailed on-site investigation to identify the presence and/or boundaries of wetlands and/or open waters. RSB Environmental 26

31 8.0 FINDINGS AND OPINIONS RSB has performed this of the Subject Property in conformance with the scope and limitations of ASTM Standard E Any exceptions to, or deletions from, this practice are described in Section 1.0 of this report. This assessment has identified no evidence of recognized environmental conditions (RECs), historical recognized environmental conditions (HRECs), controlled recognized environmental conditions (CRECs), de minimis conditions, and conditions outside the scope of ASTM Practice E in connection with the Subject Property.
