1.0 SUMMARY

This report is prepared for use by Clarendon County and presents the findings of a

Phase I Environmental Site Assessment of the approximately three (3)-Acre Property for the

Proposed Turbeville Fire Station No. 2 located along US Highway 378 in the Town of Turbeville in Clarendon County, South Carolina. The subject property is identified as Clarendon County

Tax Map Number (TMS#) 316-16-04-017-00 (3-Acres). The subject property is currently owned by Clarendon County, which will be further detailed in Section 3.4 – Past Site Use and

Ownership. Clarendon County requested and authorized that Alliance Consulting Engineers, Inc. conduct a Phase I Environmental Site Assessment to satisfy the Landowner Liability

Protections in conjunction with Due Diligence for the subject property.

Alliance Consulting Engineers, Inc. conducted a site reconnaissance on June 19, 2023, to determine if the subject property is subject to recognized environmental conditions. Tasks conducted during the site reconnaissance included observation of the general hydraulic and hydrogeologic conditions of the subject property and surrounding areas, a vehicular tour of the vicinity to observe sites identified during the records review, and a pedestrian reconnaissance to assist in determining the history of the subject property. No items observed during the site reconnaissance were identified as recognized environmental conditions with regard to the subject property.

Three (3) facilities were identified within the approximate minimum search distance in the vicinity of the subject property as a result of the records review. Based on the regulatory records and interviews with key government officials, the facilities identified during the records review are not considered recognized environmental conditions with regard to the subject property. The results of the records review will be further detailed in Section 7.0 – Findings and

Opinions.

2.0 INTRODUCTION

2.1 Purpose

The purpose of this Phase I Environmental Site Assessment (ESA) is to determine if the approximately three (3)-Acre Property for the Proposed

Turbeville Fire Station No. 2 is subject to recognized environmental conditions (RECs). The Phase I ESA has been performed in general conformance with the provisions set forth in the American Society for Testing and

Materials (ASTM) E1527-21 Standard Practice for Environmental Site Assessments:

Phase I Environmental Site Assessment Process. Per the approval of the United States

Environmental Protection Agency (USEPA), which went into effect on February 13, 2023, an assessment performed in accordance with this standard meets requirements for All

Appropriate Inquiry (AAI) as per 40 CFR Part 312 and may permit the user to qualify for certain Landowner Liability Protections (LLPs). This Phase I ESA has been conducted to satisfy the requirements of AAI rule as detailed in 40 CFR Part 312.20E. ASTM defines the term, recognized environmental conditions, as the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property due to a release or likely releases to the environment; under conditions indicative of a release to the environment; or under conditions that pose a material threat of a future release to the environment. Under this definition likely is defined as a condition which is neither certain nor proved, but can be expected or believed by a reasonable observer based on the logic and/or experience or the environmental professional, and/or available evidence, as stated in this report to support the opinions given; and environment is defined as the navigable waters, the waters of the contiguous zone, and the ocean waters of which the natural resources are under the exclusive management authority of the United States under the

Magnuson-Stevens Fishery Conservation and Management Act; and any other surface water, groundwater, drinking water supply, land surface or sub-surface strata, or ambient air within the United States or under the jurisdiction of the United States. De minimis conditions are not recognized environmental conditions.

2.2 Detailed Scope of Services

The scope of this assessment was restricted to the environmental conditions as outlined in the ASTM E1527-21 Standard Practice. The findings, opinions, and conclusions presented in this report are based on information obtained during the environmental site assessment, as well as from Alliance Consulting Engineers, Inc.'s prior experience. If additional information that might impact these environmental conclusions becomes available, it is requested that Alliance Consulting Engineers, Inc.

be granted the opportunity to review the information and reassess any potential concerns.

This assessment does not constitute an environmental compliance audit and does not include an assessment of environmental conditions associated with cultural and historical risks, protected and endangered species, vapor intrusion, or controlled substances. In order to accomplish the stated objectives, the following engineering services were performed:

A. A site reconnaissance to the property to visually and/or physically observe the site conditions relative to environmental concerns;

B. A pedestrian and vehicular reconnaissance of the subject property and surrounding areas to determine if obvious adjacent land use might suggest potential environmental concerns;

C. A query of reasonably ascertainable environmental records available from the South Carolina Department of Health and Environmental Control

(SCDHEC) and the US EPA;

D. A review of select available documents to aid in assessing the historical and current uses of the subject property and adjoining properties;

E. A brief, qualitative hydraulic evaluation of the subject property and vicinity to characterize the area drainage patterns; and

F Interviews with the Key Site Manager, a person identified by the owner or operator of the subject property with good knowledge of the uses and physical characteristics of the subject property, a representative of the prospective user, and local government officials.

This Phase I ESA and its findings are limited to the subject property. No investigations or assessments of adjoining properties, beyond historical property use examinations, were included within the scope of this Phase I ESA.

2.3 Significant Assumptions

The following are assumptions of this Phase I ESA:

• Data obtained from the public records is accurate and current;

• Groundwater flows follow the general topography of the land surface; and

• Information gathered from interviews was given in good faith and is based on actual knowledge.

2.4 Limitations and Exceptions

The practice of completing a Phase I ESA is intended to permit a user to satisfy one (1) of the requirements to qualify for the Landowner Liability Protections (LLPs) that constitutes all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice. As such, ASTM E1527-21 seeks to reduce, but not eliminate, uncertainty regarding recognized environmental conditions in connection with the subject property. Further, all appropriate inquiry does not imply an exhaustive assessment of real property, but instead calls for the environmental professional to identify a balance between competing demands of limited cost and time and the reduction of uncertainty about unknown conditions.

The findings, opinions, and conclusions presented in this report are based on reasonably ascertainable information and are representative of the conditions of the property at the time of the evaluation. It is important to note the ability to complete the services involved with the review of public records and maps as well as the ability to conduct interviews with appropriate individuals is highly dependent upon the time frame of the project schedule. In some instances, further review of information and/or additional interviews of other individuals cannot be obtained within the required timeline for completion.

2.5 Special Terms and Conditions

This report is prepared for the use of Clarendon County and presents the findings of a Phase I ESA of the approximately three (3)-Acre Property for the Proposed

Turbeville Fire Station No. 2. Any use, reuse, or adaptation of this environmental site assessment by other parties will be at such parties’ sole risk and without liability or legal exposure to Alliance Consulting Engineers, Inc. Furthermore, other parties shall, to the fullest extent permitted by law, indemnify and hold harmless Alliance Consulting

Engineers, Inc. from all claims, damages, losses, and expenses, including attorney’s fees resulting from the misuse of or alterations to the data contained within the environmental site assessment.

3.2 Site and Vicinity General Characteristics

The Property for the Proposed Turbeville Fire Station No. 2 is located within the town limits of the Turbeville, approximately eighteen (18) miles northeast of the City of

Manning, Clarendon County, approximately nineteen (19) miles east of the City of

Sumter, Sumter County, and approximately fifty-nine (59) miles east of the Capital City of Columbia, Richland County, South Carolina. The subject property is also located approximately five (5) miles east of the intersection of US Highway 378 and Interstate

95 at Exit 135. The subject property is bound to the south and east by forested land, to the north by US Highway 378, and to the west by a small patch of trees and Turbeville

Children’s Home. US Highway 378 is a four (4)-lane paved roadway with a paved median that extends along the northern boundary and provides access to the subject property.

3.3 Current Site Use

The subject property encompasses approximately three (3)-Acres and is currently cleared and maintained grass with a small portion that remains forested. Water main infrastructure is present along the northern boundary and while there are other underground utilities assumed to be nearby, their location is beyond the scope of this

Phase I ESA. Photographs of the subject property are presented in Appendix A.

3.4 Past Site Use and Ownership

A review of the Clarendon County Tax Maps and recorded deeds and plats, indicate that the subject property is comprised of TMS# 316-16-04-017-00. Information gathered from review of Clarendon County Tax Maps, recorded deeds and plats, and personal interviews indicate that the subject property has primarily been forested land until the addition of the covered sheds on the southern parcel. The reasonably ascertainable ownership histories of the parcels identified are presented below.

Clarendon County Tax Map Number 185-00-02-017-00 (3-Acres)

April 13, 2022: Clarendon County acquired the property from the Free Will

Baptist Orphanage of South Carolina, Inc.

January 14, 1956: Free Will Baptist Orphanage of South Carolina, Inc. acquired the property from D. R. Coker.

3.5 Adjoining Property Uses

Adjacent and adjoining properties are primarily forested or residential in nature.

Three (3) properties are located adjacent to the subject property, and information for the owners of the adjoining properties can be found in Table 1.

3.6 Drainage

Surface and subsurface drainage is often of interest during an Environmental Site

Assessment because it provides an indication of the direction in which contaminants could potentially be transported by surface waters or groundwater. Based upon a review of Clarendon County’s FEMA Flood Map (Exhibit F), the subject property is identified in Zone X, which designates areas of minimal flooding. A review of the NWI Map

(Exhibit G) indicates a small area of Freshwater Forested/Shrub potential wetlands on the subject property. Per the Clarendon County Soil Survey (Exhibit E), the subject property is comprised of Fuquay (FuB) and Lynchburg (Ly) series soils. Fuquay series soils are of Hydraulic Soil Group (HSG) A. Soils in HSG A are well drained with high permeability. Lynchburg series soils are of HSG B/D. Soils in HSG B are moderately drained with moderate permeability and soils in HSG D have very poor drainage with very slow permeability and are typically shallow over nearly impervious material. Dual class soils follow the drainage and permeability of their first HSG group when present in drained locations. Only soils in HSG D in their natural condition are assigned to dual classes. Since perimeter soil characteristics are neither conducive nor restrictive of passage of contaminants to the subject property due to average drainage, it is unlikely that soil composition will have much bearing on whether contaminants from off-site locations will impact the subject property.

The subject property is comprised of negligible slopes. The precise direction of groundwater flow is a parameter that is not always easily discernible for a particular site and is beyond the scope of this assessment. A USGS Topographic Map dated 2020

(Exhibit D) was used to characterize suspected drainage patterns on the subject property.

Based on the topography of the subject property, it is believed that stormwater will meander south and east toward Horse Branch.

4.0 REGULATORY RECORDS REVIEW

One (1) primary purpose of this Phase I ESA was to perform a sufficient assessment to identify obvious, actual, and potential sources of contamination that might be associated with the subject property in question. Information related to the past and present use of the subject property is of extreme interest in assessing its environmental condition. Recognition of the manner in which human activities have affected a tract of land is vital in evaluating the impact that these activities may have had on the subject property and the environment.

Alliance Consulting Engineers, Inc. utilized the services of its sub-consultant, Environmental Data Resources, Inc. (EDR), to query the environmental regulatory lists available through the US EPA and

SCDHEC for any regulated sites within the approximate minimum search distance from the subject property boundary. A detailed list of database acronyms is included in the Environmental

Data Reports dated June 2, 2023, which are presented in their entirety as Appendix B.

Two (2) facilities were identified within the limits of the approximate minimum search distance of the subject property boundary on the EDR Radius Map Report (Appendix B). The sites are presented in Table 2.

* Distances are measured radially from the centroid of the property boundary.

In addition to the records review, EDR completed an Aerial Photo Decade Package, Certified Sanborn Map Report, Historical Topographic Map Report, and City Directory Image

Report for the subject property (Appendix B). Historical aerial photographs documenting the uses of the subject property for 1957, 1959, 1961, 1964, 1975, 1978, 1983, 1989, 1994, 2006, 2011, 2015, and 2019 were included within the report. The subject property appears to have been agricultural land and has never been developed. US Highway 378 is present near the subject property in the image dated 1957. Residential dwellings appear to the west of the subject property in the image dated 1978 and with the exception of a school facility expansion farther to the west, there are no discernible changes from the image dated 1978 to present.

The Certified Sanborn Map Report for the subject property completed by

EDR indicated that fire insurance maps were not available for the subject property. The Historical Topographic Map Report includes topographic data collected in 1920, 1921, 1947, 1983, 1990, 2014, 2017, and 2020 of the subject property. The

City Directory Image Report for the subject property completed by EDR provides occupancy information obtained via USA Services for addresses located off of US Highway 301, adjacent to the subject property, for 2005, 2010, 2014, 2017, and 2020.

To assist in determining the possibility of hazardous substances or petroleum products in the subsurface environment through vapor migration to the subject property from facilities within the approximate minimum search distance of the subject property, Alliance Consulting

Engineers, Inc. consulted the EDR Vapor Encroachment Screen (VEC) prepared using EDR’s

Vapor Encroachment Worksheet, which references databases comprising of facilities likely correlated with hazardous substance or petroleum product vapor contamination due to typical operations at the facilities. A Vapor Encroachment Screen conducted in accordance with ASTM

E 2600-10: Vapor Encroachment Screening is used to identify, to the extent feasible pursuant to ASTM E 2600-10, if a VEC exists at the property. ASTM E 2600-10 defines a VEC as the presence or likely presence of hazardous substances or petroleum product vapors in the subsurface of the subject property caused by the release of vapors from contaminated soil or groundwater either on or near the property. ASTM E 1527-21 states that a Vapor Encroachment

Screen is not required to achieve compliance with all appropriate inquiries; however, a Vapor

Encroachment Screen can be useful in conducting an environmental site assessment of a subject property to assist in determining whether hazardous substance or petroleum product vapors are migrating towards the property. ASTM E 1527-21 describes migration as the movement of hazardous substances or petroleum products in any form, including solid and liquid at the surface or subsurface, and vapor in the subsurface. The Vapor Encroachment Screen conducted for approximately twenty-eight (28)-Acre Property for the Proposed Public Works and Animal

Control Facilities indicated there were no facilities within the approximate minimum search distance from the subject property therefore there are no VECs with regard to the subject property.

ASTM E 1527-21 states that all obvious uses of the subject property shall be identified from the present, back to the property’s first developed use, or back to 1940, whichever is earlier.

A review of standard historical sources at less than approximately five (5) year intervals is not required by ASTM E1527-21. The standard also states that if the specific use of the subject property appears unchanged over a period of longer than five (5) years, then it is not required to research the use of the subject property during that time. The subject property appears to have been undeveloped since 1957, per the Aerial Photo Decade Package and can be assumed to have been undeveloped at least as far back as 1940.

5.0 SITE RECONNAISSANCE

5.1 Methodology and Limiting Conditions

Alliance Consulting Engineers, Inc. performed a site reconnaissance of the subject property on June 19, 2023. The subject property was observed by traversing the perimeter and interior of the property. The reconnaissance involved viewing adjoining properties and structures from publicly accessible areas. Observation of nearby properties was limited to areas visible in the line of sight from public roadways. A vehicular tour of the area was made to confirm the locations of facilities listed by regulatory agencies and to verify nearby land use.

5.2 Exterior Observations

Exterior conditions or items that were observed are depicted in Table 3.

6.0 INTERVIEWS

On July 12, 2023, Mr. David Epperson, the Key Site Manager of the subject property and End User this Phase I ESA, indicated that to the best of his knowledge and belief there are currently no known nor have been any environmental liens or governmental notifications relating to environmental laws; nor any past, threatened, or pending lawsuits or administrative proceedings concerning a release or threatened release of hazardous substances or petroleum products on the property. Mr. Elliott did not have any additional knowledge of any hazardous substances, petroleum products, unidentified waste materials, tires, automotive or industrial batteries, or other waste materials being dumped above grade, buried, and/or burned on the subject property. This correspondence is included in Appendix C.

7.0 FINDINGS AND OPINIONS

During the records review and site reconnaissance, the subject property features, activities, uses and conditions, which may indicate the presence or likely presence of hazardous substances or petroleum products at the subject property, were reviewed to determine if the findings, but not necessarily all findings, may be indicative of a recognized environmental concern (REC), controlled environmental concern (CREC), historical environmental concern

(HREC), or de minimus conditions.

McElveen’s Colonial Station (McElveen) is located 0.286 miles west northwest and upgradient of the subject property. Witherspoon is listed on the Registry of Conditional

Remedies (RCR) database, Faculty Index System (FINDS) database, and Groundwater

Contamination Inventory (GWCI) database. McElveen is on the RCR database due to a release that occurred on December 20, 1991, that contaminated the groundwater. A Corrective Action

Plan as implemented with the Conditional Remedy for attaining levels below the Conditional

Use Maximum Contaminant Level (CU-MCL) met on March 10, 2003. This release and inclusion on RCR database is the reason for McElveen’s listing on the GWCI and FINDS database. Although McElveen is upgradient of the subject property, the CU-MCL was met in

2003, and it is the opinion of the environmental professional that McElveen is not considered an REC with regard to the subject property.

Ray and Donald Coker (Coker) is located 0.498 miles west and upgradient of the subject property. Coker is listed on the Leaking Underground Storage Tank (LUST) database and

Underground Storage Tank (UST) database. Coker is on the LUST database for one (1) release on August 22, 1991, with cleanup initiated on August 22, 1991, and a No Further Action (NFA) determination on January 16, 1995. Coker is listed on the UST database for three (3) abandoned tanks. These tanks include two (2) 6,000-gallon Gasoline tanks and one (1) 4,000-gallon

Gasoline tank. Although Coker is upgradient of the subject property, there was a NFA determination made in 1995 pertaining to the LUST release, and it is the opinion of the environmental professional that Coker is not considered an REC with regard to the subject property.

Nothing observed during the site reconnaissance is considered an REC with regard to the subject property.

8.0 CONCLUSIONS

The Phase I ESA has been performed in conformance with the scope and limitations of

ASTM E 1527-21: Standard Practice for Environmental Site Assessments of the subject property. Any exceptions to, or deletions from, this practice are described in Section 9.0 of this report. This assessment has revealed no evidence of a recognized environmental conditions in connection with the approximately three (3)-Acre Property for the Proposed Turbeville Fire

Station No. 2. No further environmental assessment is needed at this time.
