EXECUTIVE SUMMARY

LRS Federal, LLC (LRS), under subcontract to Whitetail Environmental, LLC was authorized to prepare an Environmental Condition of Property (ECP) Report for the Roark Hall United States Army Reserve Center (USARC), hereafter referred to as the “Property”.

The Property is located at 21 Kraus Road, Oceanside, California (CA) 92055. The purpose of this ECP is to determine the environmental condition of the Property prior to the proposed construction of the new Area Maintenance Support Activity (AMSA)/Vehicle Maintenance Shop (VMS) and demolition of four existing buildings.

The Property is located at the southernmost portion of Marine Corps Base (MCB) - Camp Pendleton. MCB - Camp Pendleton was established in the 1940s and is the largest MCB in the country. A Host-Tenant agreement was created in 1976 in which MCB - Camp Pendleton (Host) provided land to the Army (Tenant) for the purposes of a Reserve Center. MCB - Camp Pendleton holds the land on its records and the Army is to hold the buildings on its records.

The Property includes approximately 11.38 acres of land improved with four buildings (Army Reserve Center Building – Roark Hall, Army Reserve Vehicle Maintenance Shop, Oil Storage Building, and Hazardous Material Storage Building), two mobile office trailers, numerous Conex storage containers, paved parking areas, and landscaped areas with trees and scrubs. The Property is bordered by MCB - Camp Pendleton to the north, east, and west and the Oceanside Yacht Club and Harbor to the south. The United States (U.S.) Army Reserve 63d Readiness Division (RD) was observed during the site inspections conducted on 16 March 2023 to currently occupy the Property. The Property is relatively flat with a ground surface elevation of 17 feet above mean sea level.

The Property is used by the U.S. Army Reserve 63d RD for administrative services, classroom training, area maintenance support, and vehicle maintenance. The U.S. Army Reserve 63d RD is proposing to construct a 10,853 square feet AMSA/VMS on the western portion of the Property. The proposed AMSA/VMS will include a vehicle wash rack/platform, bi-level equipment loading ramp, overhead crane, and accessibility for the disabled. The contractor performing demolition work at the Property will be responsible for complying with all necessary regulations. Prior to demolition, a Demolition Plan will be prepared and approved by the Contracting Officer.1

This ECP Report was prepared in conformance with 42 United States Code § 9620(h), Army Regulation (AR) 200-1 (13 December 2007) and in general conformance with the American Society for Testing and Materials (ASTM) Designation D6008-96 (2014), 1 As required by Unified Facilities Guide Specifications, Section 02 41 00: Demolition and Deconstruction.

RECOGNIZED ENVIRONMENTAL CONDITIONS

A Recognized Environmental Condition (REC) is defined by ASTM D5746-98 (2016) as the presence or likely presence of hazardous substances or petroleum products on any DoD real property under conditions that indicate an existing release, a past release, or the material threat of a release of any hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property. The term includes hazardous substances or petroleum products even under conditions in compliance with laws. The term is not intended to include de minimus conditions that generally do not present a material risk of harm to the public health or environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies.

There were no RECs identified for the Property. Table E-1 provides a Project Environmental Overview of conditions at the Property. This table provides a brief description of environmental conditions that were evaluated during the ECP process.

Detailed information associated with this overview is provided in the remaining portion of the document in the designated Section number identified.

Other Environmental Conditions Fuel spills were reported and documented at the Property on 10 March 2001 and 2 June 2005. Approximately 100 gallons and 50 gallons of fuel were released at the Property on 10 March 2001 and 2 June 2005, respectively. All fuel spilled was recovered and impacted soil was transported offsite for disposal. An interview conducted as part of this ECP indicated that a small oil spill occurred at the Property during the summer of 2022. No further information was provided regarding the spill or quantity. Therefore, the spills/releases are not considered a REC. Due to the relatively small quantities, full recovery of fuel, and removal of impacted soil from the site, the spills/releases are considered de minimis conditions and are not considered RECs.

Contamination was identified at several facilities within the recommended minimum search distances of the Property. Violations were reported regarding the failure to clean up a spill/release of hazardous material and the disposal or causing of the disposal of hazardous waste to an unauthorized point (ground, storm drain, sewer system, trash, or air) at the Oceanside Yacht Club and Harbor located adjacent and south of the Property.

This facility is located downgradient, across the North Harbor (which may serve as a hydraulic barrier). Due to the hydraulic gradient and potential hydraulic barrier separating

Roark Hall United States Army Reserve Center

PAGE ES-3

the Oceanside Yacht Club and Harbor from the Property, the spills/releases are not considered a REC.

Soil contamination was reported at two buildings (Buildings 210533 and 21453) associated with MCB – Camp Pendleton due to underground storage tank (UST) leaks.

These buildings are located north of the Property. Soil contamination was remediated at these buildings and the site status is listed as “Complete – Case Closed”. Due to the closure status and completed remediation activities, the spills/releases are not considered a REC.

A former firing/artillery range associated with MCB – Camp Pendleton was located approximately one mile south of the Property. The Cleanup Status is listed as No Further Action. Therefore, the historical presence of a firing/artillery range located approximately one mile south of the Property is not considered a REC.

OTHER PROPERTY CONDITIONS

12 Munitions & Explosives

A former indoor firing range was located within the Army Reserve Center (Roark Hall).

The former indoor firing range was converted into office space in approximately 1996.

Clean-up/decontamination activities, including the removal of a bullet stop steel plate, sand and fiberglass insulation behind the steel plate, acoustic ceiling tiles and grid, and fluorescent light fixtures, were conducted at the former indoor firing range in 2006.

Confirmation sampling confirmed that the cleanup criteria had been achieved for the entire former indoor firing range and that the former indoor firing range is clear for future adult use.

No 6.2.3

13 Asbestos Containing Materials

A building survey was completed at the Army Reserve Vehicle Maintenance Shop at the Property in 1996. The building survey identified suspect asbestos-containing material (ACM) within the exterior stucco, fire doors, and electrical wiring. According to the

No 6.2.1

Roark Hall United States Army Reserve Center

Affect Community

Environmental Response Facilitation

Act (CERFA) Category?

Section No.

Asbestos Operation and Management (O&M) Plan, ACM within the exterior stucco was classified as nonfriable. These materials were not sampled but should be assumed to contain asbestos until tested.

ACM sampling was conducted at the Army Reserve Vehicle Maintenance Shop (VMS) at the Property in 2003. ACM sampling concluded that the black rolled roofing felts, gray roofing mastic, gray window putty, white 12-inch by 12-inch floor tiles and associated black mastic, and brown glue associated with 4" cove base contain asbestos. According to the Asbestos O&M Plan, the friability of ACMs identified in the VMS is unknown.

ACM sampling was conducted for brown mastics adhering to the fiberglass panels behind steel plates at the former indoor firing range at the Property in 2006. ACM was not detected in the samples collected from the former indoor firing range at the Property. This appears to be the extent of ACM sampling at the old firing range.

The Army Reserve Center Building (Roark Hall) and Hazardous Material Storage Building were constructed in 1972. Therefore, ACM is likely present within these buildings.

The Oil Storage Building was constructed in 1996; therefore, ACM is not likely present.

14 Lead-Based Paint

Lead-based paint (LBP) sampling was conducted at the Army Reserve Vehicle Maintenance Shop at the Property in 2003.

Multiple surfaces were found to be lead based.

Lead sampling was conducted at the former indoor firing range at the Property in March 2006. Lead contaminated dust (greater than or equal to 50 micrograms per kilogram [µg/ft2] for interior floor surfaces, 250 µg/ft2 for interior horizontal window surfaces, and 800 µg/ft2 for exterior floor and horizontal window surfaces)

was detected at concentrations ranging from below the detection limit to 17,000 µg/ft2.

A follow-up industrial hygiene survey was conducted at the former indoor firing range at the Property in April 2006. Lead contaminated dust (greater than or equal to 50 µg/ft2 for interior floor surfaces, 250 µg/ft2 for interior horizontal window surfaces, and 800 µg/ft2 for exterior floor and horizontal window surfaces) was detected at concentrations ranging from below the detection limit to 580 µg/ft2. Bulk samples obtained from ceiling tiles, fiberglass insulation, and duct wrap were below the detection limit. However, LBP (greater than or equal to 0.5 percent weight [WT%]) was detected in bulk samples obtained from the brown paint on the steel truss. The sample concentration of the brown paint on the steel truss was 0.99 WT%.

Additional sampling was conducted at the former indoor firing range at the Property in November 2006. Lead contaminated dust (greater than or equal to 50 µg/ft2 for interior floor surfaces, 250 µg/ft2 for interior horizontal window surfaces, and 800 µg/ft2 for exterior floor and horizontal window surfaces) was detected at concentrations ranging from below the detection limit to 1,300 µg/ft2.

A Lead Dust-Wipe Clearance Inspection was conducted at the former indoor firing range at the Property in December 2006. The Department of the Army’s Interim Guidance for the Lead Cleanups at Indoor Firing Ranges established the concentration of 200 µg/ft2 as the threshold limit. Sample concentrations ranged from below the detection limit to 130 µg/ft2. Lead contaminated dust was detected below the 200 µg/ft2 threshold limit at the former indoor firing range at the Property.

Therefore, the cleanup criteria had been achieved for the entire former indoor firing

range. The Department of the Army confirmed that lead abatement activities were performed in accordance with the Interim Guidance for the Lead Cleanups at Indoor Firing Ranges and as such clears the former indoor firing range for future adult use.

The Army Reserve Center Building (Roark Hall), Army Reserve Vehicle Maintenance Shop, and Hazardous Material Storage Building were constructed in 1972. Therefore, LBP is likely present within these buildings.

The Oil Storage Building was constructed in 1996; therefore, LBP is not likely present.

15 PCB Equipment

No documentation could be found on polychlorinated biphenyls (PCBs); however, window putty is known to contain PCBs and should be assumed to be PCB-containing unless tested. Pole mounted transformers are located around the Property. The transformers are assumed to be owned by MCB – Camp Pendleton. There were no PCB labels on the transformers. The age of the transformers are unknown. According to the United States Environmental Protection Agency’s (USEPA) PCB Question and Answer Manual, transformers must be assumed to be PCB-containing if the date of manufacture is unknown. It is also possible that PCB-containing fluorescent light ballasts exist at the Property.

No 2.2.3.15, 6.2.4

16 Radon

Radon concentrations in San Diego County, CA average 0.677 picocuries per liter (pCi/L) on the first floor living area and 0.400 pCi/L on the second floor living area which are below the 4.0 pCi/L action level established by USEPA. Radon concentrations in basements were not reported for San Diego County, CA.

There are no records indicating that radon testing has occurred at the Property.

There are no suitable habitats for the identified threatened and endangered species at the Property and the Property has been developed. Therefore, it is presumed that the aforementioned threatened and endangered species are not present at the Property.

22 Cultural Resources

A Final Historic Buildings and Structures Survey and Evaluation was conducted at MCB – Camp Pendleton in February 2016.

The survey concluded the following:

• Las Flores Adobe (a National Historic

Landmark) and the Santa Margarita Ranch House are properties significant for their pre-military history and are listed in the National Register of Historic Places

(NRHP).

• Buildings 1133 and 51811 are recommended as eligible for the NRHP.

A Cultural Resource Evaluation was prepared for the Property in 2022. The following recommendations were provided within the Cultural Resource Evaluation:

• The archaeological sensitivity of the

Property is low. No archaeological sites have been recorded within the Property or within a quarter mile radius. Therefore, archaeological surveying or monitoring is not recommended at the Property prior to ground disturbing activities.

• The architectural sensitivity of the Property is low. The Army Reserve Center Building (Roark Hall), Army Reserve Vehicle Maintenance Shop, and Hazardous Material Storage Building at the Property were constructed in 1972 and determined to not be eligible for listing in NRHP. The State Historic Preservation Office concurred with the aforementioned assessment of the three buildings. The Oil

This ECP adheres to 42 United States Code (USC) § 9620(h), AR 200-1 (13 December 2007), DoD 4165.66-M (1 March 2006), and follows the American Society for Testing and Materials (ASTM) D5746-98 (2016), Standard Classification of Environmental Condition of Property Area Types for Defense Base Closure and Realignment Facilities as a guideline when not inconsistent with U.S. Army regulations and other applicable U.S.

Army guidance.

This ECP covers the approximate 11.38-acre Property located at 21 Kraus Road, Oceanside, CA 92055 in San Diego County. This ECP recommends classification of the Property into one of seven DoD Environmental ECP categories as defined by the ASTM Designation D5746-98 (2016), Standard Classification of Environmental Condition of Property Area Types for Defense Base Closure and Realignment Facilities. The property classification categories are as follows:

• ECP Area Type 1 – An area or parcel of real property where no release, or disposal of hazardous substances or petroleum products or their derivatives has occurred (including no migration of these substances from adjacent properties).

• ECP Area Type 2 – Where only the release or disposal of petroleum products or their derivatives has occurred.

• ECP Area Type 3 – An area or parcel of real property where release, disposal, or migration, or some combination thereof, of hazardous substances has occurred, but at concentrations that do not require a removal or remedial action.

• ECP Area Type 4 – An area or parcel of real property where release, disposal, or migration, or some combination thereof, of hazardous substances has occurred, and all remedial actions necessary to protect human health and the environment have been taken.

• ECP Area Type 5 – An area or parcel of real property where release, disposal, or migration, or some combination thereof, of hazardous substances has occurred, and removal or remedial actions, or both, are under way, but all required actions have not yet been taken.

Roark Hall United States Army Reserve Center

• ECP Area Type 6 – An area or parcel of real property where release, disposal, or migration, or some combination thereof, of hazardous substances has occurred, but required response actions have not yet been initiated.

• ECP Area Type 7 – An area or parcel of real property that is unevaluated or requires additional evaluation.

Additionally, this ECP recommends classification of the Property into one of three Military Construction (MILCON) categories as defined by AR 200-1 (2007), Environmental Protection and Enhancement. The property classification categories are as follows:

• Category I – There is no reason to expect contamination will be encountered during the construction.

• Category II – There is no known contamination, there remains some potential that contamination may be encountered during construction.

• Category III – The site is known to be contaminated or there is strong suspicion contamination will be encountered during construction.

1.3 ASSUMPTIONS AND LIMITATIONS

The information obtained from individuals interviewed was considered to be accurate unless reasonable inquiries indicated otherwise. Conditions observed were considered representative of similar areas that were not accessible unless otherwise indicated. This ECP Report presents a summary of reasonably ascertainable information on the environmental conditions of, and concerns relative to, the land, facilities, and real property assets at the Property. Its findings are based on a record search of publicly-available documents, a thorough review of reasonably ascertainable documents, a site reconnaissance of the Property conducted on 16 March 2023, and interviews with personnel knowledgeable about the Property and its history. Existing environmental investigations and reports and historical documents were reviewed in support of this ECP.

Information obtained from these other sources is reflected within this report by reference.

All Property buildings and structures were visually inspected during the site reconnaissance. However, a 100 percent (%) visual reconnaissance of every single interior space within each building (e.g., attics, crawl spaces, etc.) was not practical due to accessibility restrictions.

This report has been prepared in compliance with ASTM D5746-98 (2016), Standard Classification of Environmental Condition of Property Area Types for Defense Base Closure and Realignment Facilities. In preparing this report, LRS has relied on certain information provided by federal, state, and local officials and other parties referenced therein, and on information contained in the files of governmental agencies, that were reasonably ascertainable at the time of this assessment. Although there may have been some degree of overlap in the information provided by these various sources, an attempt

Roark Hall United States Army Reserve Center to independently verify the accuracy or completeness of all information reviewed or received during the course of this site assessment was not conducted. Observations were made of the Property and of the structures on the Property as indicated in this report.
