EXECUTIVE SUMMARY

Medina Consulting Company, Inc. (MCC) performed a Phase I Environmental Site Assessment (ESA) using the guidance provided by the ASTM International Standard E1527-13 Standard Practice for Environmental Site Assessments, Phase I Environmental Site Assessment Process and 40 Code of Federal Regulations (CFR) Part 312; Standards and Practices for All Appropriate Inquiries for the 13.667-acre tract at 10712 Lower Seguin Rd. in Schertz, Bexar County, Texas (“the Site”). The Site is owned by the Louie T. Engelke Revocable Living Trust and the Bexar County Appraisal District Property ID is 619052. The objective of our services was to identify and record obvious existing or potential conditions that could cause potential environmental liability to, or restrict the use of, the subject property. The scope of work performed, objectives, extent and limitations of the services are described in more detail in the text of the report.

The Site is a 13.667-acre tract located southeast of Lower Seguin Road. The northern part if the Site is cleared land with a residence, workshop, and two livestock pens. The residence and workshop were being used; however, the livestock pens were not. The southeastern two thirds of the Site was undeveloped land covered primarily in brush, grass, and trees. Land use in the vicinity was primarily agricultural, with a few residences. Randolph Oaks Golf Course and JBSA- Randolph are about 1.800 feet north of the Site.

In summary, our findings are:

Historical Review: The historical review of the available historical information indicates the Site has been agricultural land since at least 1938 through 1966. By 1973, a residence and farm building were constructed on the northwest part of the Site. The southeastern part of the property remained mostly undeveloped land with brush, grass, and trees.

Aquifers: The Site is not located over a sole-source aquifer according to the EPA Region VI, Sole Source Aquifer Office.

Regulatory Review: MCC reviewed selected federal and state environmental regulatory lists and conducted interviews with personnel at regulatory agencies. We did not identify facilities with environmental concerns that would likely adversely affect the Site.

Site Visit: A septic system is in use near the mobile home on the Site. Small containers of solvents, cleaners, and other maintenance materials were stored in the workshop and livestock pens. No significant leaks or spills were observed. Piles of debris and discarded items were observed near the workshop. A dry and abandoned water well was observed on the Site. No other environmental concerns were identified during the site reconnaissance conducted May 11, 2017.

Vapor Intrusion Screen: MCC conducted an initial Tier 1 Vapor Encroachment Screen.

Based on the environmental review, a vapor encroachment condition (VEC) is unlikely to be an issue of concern in connection with structures on the Site at this time.

Conclusions:

We have performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM Practice E1527 of the 13.667-acre tract located at 10712 Lower Seguin Road in Schertz, Bexar County, Texas (“the Site”). Any exceptions to, or deletions from, this practice are described in Section 11.0 of this report. This assessment has revealed no evidence of recognized environmental conditions in connection with the Site.

Recognized environmental conditions are defined by the ASTM International Standard E1527-13 as:

the presence or likely presence of any hazardous substance or petroleum products in, on, or at a property (1) due to a release, (2) under conditions indicative of a release to the environment, or (3) under conditions that pose a material threat of a release. No releases or hazardous materials or petroleum products were identified on the Site. No ASTM International Recognized Environmental Conditions were identified at the Site; however, other conditions that are subject to environmental regulations were observed, including the following:

Out of Use Water Well: Abandoned wells are regulated by the TDLR and local GCDs through the Texas Occupations Code, sections 1901.255 and 1901.256. “Abandoned well" means a well that is not in use. According to state law (Sec. 1901.255. Plugging Water Well), a well is considered abandoned if it has not been used for six consecutive months. However, even a well that has not been used for six consecutive months can be considered in use if it falls into one of the following two categories: A non-deteriorated well that contains the casing, pump, and pump column in good condition, or a non-deteriorated well that has been capped. Texas law makes the landowner responsible for plugging abandoned wells.

Discarded Materials: A person commits an offense if the person disposes or allows or permits the disposal of litter or other solid waste that is not an approved Solid Waste Site (Health and Safety Code, Title 5, Subchapter B, Chapter 365: Litter, Subchapter A: General Provisions). Solid waste debris was observed on the Site, although the amount of solid waste was relative small and unlikely to be of interest to regulatory agencies.

Septic System: The septic system on the Site is in use and not an environmental issue. If the septic system is taken out of service, TAC Title 30 Rules §285.36: Abandoned Tanks, Boreholes, Cesspools, and Seepage Pits states:

(a) A tank that is not to be used again for holding sewage shall be abandoned.

(b) To properly abandon, the owner shall conduct the following actions, in the order listed.

(1) All tanks, boreholes, cesspools, seepage pits, holding tanks, and pump tanks shall have the wastewater removed by a waste transporter, holding a current registration with the executive director.

(2) All tanks, boreholes, cesspools, seepage pits, holding tanks, and pump tanks shall be filled to

Page iii ground level with fill.

MCC reserves the right to alter our opinions and conclusions based on our review of information received after the date of this report.

Recommendations:

Based on the reasonably ascertainable information reviewed during this assessment, MCC does not recommend further assessment of the Site at this time. Debris piles on the property that are in violation of state and local codes should be properly disposed. The out of use water well, if abandoned, should be properly plugged and abandoned. When taken out of use, the septic system will also need to be properly abandoned.

1.0 INTRODUCTION AND SCOPE OF SERVICE

1.1 Purpose

The purpose of the Phase I ESA is to identify reasonably observable, on site and/or adjacent potential sources of contamination, which could adversely affect the environmental quality of the Site, and to ascertain the possibility of site contamination that may have resulted from historical use of the Site.

This Phase I ESA was performed to satisfy one of the requirements to qualify for the innocent landowner, contiguous property owner, or bona fide prospective purchaser on Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) liability: that is, the practices that constitute “appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined by the ASTM International Standard E1527- 13: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process.

The opinions included herein are based upon the information obtained during the study and our professional experience. In the event that other relevant information becomes available, we request the opportunity to review the information, and to modify our opinions, if warranted.

1.2 Detailed Scope of Services

This Phase I ESA was conducted to identify recognized environmental conditions on the Site and was performed in accordance with current ASTM International standards and MCC's standard scope of services that are presented below:

Perform a site visit (reconnaissance) to look for surficial indications of past and present activities involving hazardous substances and/or petroleum products. Ms. Hope Hernandez and Mr. Kerry McEntire, environmental professionals experienced in performing environmental assessments, performed the site visit under the supervision of Mr. Douglas McGookey, P.G., an Environmental Professional of MCC, on May 11, 2017;

Conduct interviews with the current property owner(s) and/or "knowledgeable site personnel" in an attempt to determine current and/or historical on-site activities that may be relevant to the Site and/or adjoining properties;

Review selected, available, historical information, including aerial photographs, Sanborn

Fire Insurance Maps, and topographic maps (where coverage is available) of the Site and surrounding properties in an attempt to determine on-site and off-site historical activities;

Review title records pertaining to past a present property owners and land use descriptions, if provided;

Review selected, available, lists published by state and federal environmental regulatory agencies for records or comments pertaining to past or present environmental concerns at the Site and/or within the specified “search distances” from the Site. These search distances adhere to the standard distances proposed by ASTM International;

Perform a vehicular reconnaissance of selected areas in an attempt to verify the locations of listed facilities within search distances specified by ASTM International and to assist in visually identifying nearby land use which may create the potential for an adverse, environmental impact on the Site; and

Provide a written final report summarizing the Phase I ESA observations, interviews, file reviews, findings, and conclusions.

No sampling or analytical testing was conducted as part of the scope of this Phase I ESA.

1.3 Significant Assumptions

This Phase I ESA is intended to minimize, but not eliminate, uncertainty regarding potential for recognized environmental conditions in connection with the Site with reasonable limits of time and cost. It is assumed that the user has provided MCC with specialized knowledge or experience that is material to recognized environmental conditions in connection with the Site, including the reason why the property may have a significantly lower purchase price than comparable properties, if applicable (ASTM International E1527-13 Section 6.5).

In general, groundwater flow direction has been inferred based on topography in the vicinity of the Site with the assumption that shallow groundwater flow will follow surface topography or other available water resources. No site-specific measurements of groundwater depth and flow direction have been performed.

Based on this interpretation, MCC has reviewed regulatory agency information for facilities that are located within the approximate minimum search distance that, based on proximity and knowledge of potential contaminant fate and transport, may present a potential impact to the Site.

MCC has reviewed historical aerial photographs in an attempt to determine the past use of the Site and adjoining properties. Although some uses can be determined, due to the quality and scale of the photographs, few on-site details are identifiable.

1.4 Limitations and Exceptions

MCC has endeavored to meet what it believes is the standard of care for the services performed and, in doing so, is obliged to advise the user of Phase I ESA limitations. MCC believes that providing information about limitations is essential to help the user identify and thereby manage risks. These risks can be mitigated, but not eliminated, through additional research. MCC will, upon request, advise the user of the additional research opportunities available and the associated costs.

This report is an instrument of service of MCC and includes limited research, a review of specified and reasonably ascertainable listings and a site reconnaissance to identify "recognized environmental conditions" using the ASTM International Standard E1527-13; Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process.

“Recognized environmental conditions” are defined by ASTM International as (1) “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property due to any release to the environment, or (2) under condition indicative of a release to the environment under conditions that pose a material threat of future release to the environment. De minimus conditions are not recognized environmental conditions.” The Phase I ESA was performed in accordance with generally accepted practices of the profession undertaken in similar studies at the same time and in the same geographical area. MCC has observed a standard of care generally exercised by the profession under similar circumstances and conditions.

The Phase I ESA did not include any inquiry with respect to asbestos, radon, methane, lead based paint, lead in drinking water, formaldehyde, endangered species, historical significance, archeological, wetlands, subsurface investigation activities or other services or potential conditions or features not specifically identified and discussed herein.

This report represents MCC's service to the addressee as of the report date. In that regard, the report constitutes MCC's final document, and the text of the report may not be altered in any manner after final issuance of the same. Opinions relative to environmental conditions given in this report are based upon information derived from the most recent site reconnaissance date and from other activities described herein. The addressee is herewith advised that the conditions observed by our firm are subject to change. Certain indicators of the presence of hazardous materials may have been latent or not present at the time of the most recent site reconnaissance and may have subsequently become observable. In a similar manner, the research effort conducted for a Phase I ESA is limited. Accordingly, it is possible that MCC's research, while fully appropriate for a Phase I ESA and in compliance with the scope of service, may not include other important information sources. Assuming such sources exist, their information may not have been considered in the formulation of our findings and conclusions.

This report is not a comprehensive site characterization or regulatory compliance audit and should not be construed as such. The opinions presented in this report are based upon findings derived from a site reconnaissance, a review of specified records and sources and comments made by interviewees. Specifically, MCC does not and cannot represent that the Site contains no hazardous or toxic materials, products, or other latent conditions beyond that observed by our company during the site assessment. Further, the services herein shall in no way be construed, designed or intended to be relied upon as legal interpretation or advice.

The findings and conclusions contain all of the limitations inherent in these methodologies that are referred to in ASTM International Standard E1527-13.

1.5 Special Terms and Conditions

In those instances where additional services or service enhancements are included in the report as requested or authorized by the user, those services are presented in the scope of work. There are no special terms and conditions.

1.6 User Reliance

The study and report have been prepared on behalf of and for the exclusive use of HNTB Corporation, Bexar County, and Joint Base San Antonio-Randolph (formerly Randolph Air Force Base, collectively “the Client”) solely for their use and reliance in the environmental assessment of this Site. The Client is the only party to which MCC has explained the risks involved and that has been involved in the shaping of the scope of services needed to satisfactorily manage those risks, if any, from the Client’s point of view. Accordingly, reliance on this report by any other party may involve assumptions whose extent and nature lead to a distorted meaning and impact of the findings and opinions related herein. MCC's findings and opinions related in this report may not be relied upon by any party except the Client. With the consent of the Client and MCC, we may be available to contract with other parties to develop findings and opinions that relate specifically to such other parties' unique risk management concerns related to the Site.

4.2 Additional Environmental Record Sources

TCEQ Online Databases. MCC researched the LPST Database Query and Central Registry Query on the TCEQ website to ascertain records of underground storage tank installation and removal as well as and hazardous material spill incidents. No additional records were found.

4.3 Physical Setting Sources

The Schertz, Texas, 7.5-minute topographic quadrangle map (2016), obtained from the Texas Natural Resource Information System (TNRIS) and available at a scale of 1:24,000 by the United States Geologic Survey (USGS) (Figure 3) was used to determine the physical setting of the Site.

The Site appears to be relatively flat and very gently sloping to the east-southeast. The general surface area topography of the Site slopes to the east toward Womans Hollow Creek, which is located approximately three quarters of a mile from the Site.

Other published information utilized in conducting this environmental assessment is listed in Section 12.0 of this report.

4.4 Historical Use Information of the Property

4.4.5 From First Development

MCC’s review of the available historical information indicates the Site has been agricultural land since at least 1938 through 1966. By 1973, a residence and farm building had been constructed on the northwest part of the Site, and the remainder of the property has been mostly undeveloped land covered with brush, grass, and trees.

4.5 Historical Use Information of Adjoining Properties

The same standard historical sources used in the previous section (i.e. fire insurance maps, historical topographic maps, aerial photographs, etc.) were used to determine the property use of adjoining properties. Information obtained from the historical sources are summarized below.

Properties adjacent to the north, east, south, and west of the Site have been agricultural use farm and ranchland since at least 1938. Lower Seguin Road has been present North of the Site since at least 1938. Randolph Air Force Base has been present northwest of the site since it was established in 1931.

5.0 SITE RECONNAISSANCE

5.1 Methodology and Limiting Conditions

The objective of the site reconnaissance is to obtain information indicating the likelihood of identifying ASTM International recognized environmental conditions in connection with the Site to the extent not obstructed by bodies of water, adjacent buildings, or other obstacles.

Additionally, reconnaissance of the adjoining properties was performed to identify land use and the associated potential for producing recognized environmental conditions.

An unobstructed pedestrian and visual survey of the Site and adjoining properties was conducted on May 11, 2017. At the time of the site visit, the northwestern part of the Site was cleared land with a residence, a shed near a dry water well, a workshop, and two livestock pens. The remaining area southeast of the workshop was covered primarily by brush, grass, and trees. Selected photographs taken during the site reconnaissance are provided in the appendices.

5.2 General Site Setting

The Site is a 13.667-acre tract located south of Lower Seguin Road. The Site is cleared land with a residence, workshop, and two livestock pens. The residence and workshop were being used;

however, the livestock pens were not. The southeastern two thirds of the Site was undeveloped land covered primarily by brush, grass, and trees.

Photographs are attached that document our observations on the Site. Photographs 1 through 3 were taken at the northern boundary of the property and show the adjoining Lower Seguin Road and the adjacent rural properties to the north, east, and west. Photograph 4 shows the opening for a dry water well at the northern boundary of the site that was out of use. Photograph 5 shows an electrical pole attached to the shed in which the well equipment is housed. Photograph 6 shows the view from the northern perimeter of the Site towards the residence, which is a double-wide mobile home, on the Site. Photographs 7 through 9 show the residence on the Site, and the associated refrigeration, water, and electrical connections to the home. What appears to be a leak of potable water from the home has caused standing water in Photograph 9. Photograph 10 shows the location where Mr. Engelke indicated the septic tank is located. Photographs 11 through 19 show the workshop equipment, and materials stored in the workshop. Photograph 20 shows debris and materials next to the workshop. Photograph 21 shows a riding lawn mower. Photograph 22 is a view facing southwest towards the undeveloped part of the Site. The grasses, brush, and trees in the photograph are typical vegetation on the undeveloped part of the Site. Photograph 23 shows a cement trough on the Site that is no longer in use, and Photograph 24 shows the larger livestock pen. Photograph 25 shows the smaller livestock pen that is used for storage. Photograph 26 shows items stored in the smaller livestock pen. Most of the items stored appear to be empty feed bags for livestock. Photograph 27 shows the area behind the larger livestock pen. Photograph 28 shows the largely cleared northern part of the Site. Photograph 29 shows the workshop and materials stored near it. The blue plastic drum in the photo was open and empty. Photograph 30 shows lumber stored on the Site used in the workshop.

Ms. Davis responded that the City of

Schertz has no records of environmental issues for the Site.

7.0 VAPOR INTRUSION SCREEN

A vapor encroachment screen (VES) was conducted on the Site using the guidance provided by ASTM International E2600-10, Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions. An initial Tier 1 VES was evaluated as a supplement to this Phase I ESA. The same record sources and information gathered during the Phase I ESA was also used to determine the presence of a vapor encroachment condition (VEC).

The EDR Radius Map™ regulatory review reported no facilities of concern within the approximate minimum search distances from the Site as listed in ATSM Internationial E2600-10. Based on the information obtained from the regulatory review, historical review, and the current site characteristics, there is no indication that a VEC exists or is likely to exist on the Site.

8.0 FINDINGS

In summary, our findings are:

Historical Review: The historical review of the available historical information indicates the Site has been agricultural land since at least 1938 through 1966. By 1973, a residence and farm building were constructed on the northwest part of the Site. The southeastern part of the property remained mostly undeveloped land with brush, grass, and trees.

Aquifers: The Site is not located over a sole-source aquifer according to the EPA Region VI, Sole Source Aquifer Office.

Regulatory Review: MCC reviewed selected federal and state environmental regulatory lists and conducted interviews with personnel at regulatory agencies. We did not identify facilities with environmental concerns that would likely adversely affect the Site.

Site Visit: A septic system is in use near the mobile home on the Site. Small containers of solvents, cleaners, and other maintenance materials were stored in the workshop and livestock pens.
