Site Survey Report – CZQ VOR ii

Executive Summary In support of the Federal Aviation Administration (FAA) Real Property Disposition Program, the United States Department of Transportation John A. Volpe National Transportation System Center (Volpe) has completed this Site Survey Report to include the results of the site survey conducted on April 13, 2026 at the Clovis (CZQ) Very High Frequency Omnidirectional Range (VOR) (Facility) located near Clovis, CA. The Facility’s equipment building and site features are to be demolished and removed from the site. The purpose of this site survey was to determine the level of effort required to demolish, remove, and dispose of all real property on-site as required by the terms of the lease.

This report documents current site conditions, equipment inventories, environmental information, and recommended disposition and demolition actions for the site. Operations and maintenance histories were reviewed to identify any potential environmental hazards. Identified and most recognizable environmental hazards are to be handled and disposed of in an environmentally compliant manner to minimize potential worker exposures, contamination to the environment, and to achieve regulatory compliance for proper removal, disposal, and restoration.

Several risks and safety concerns, such as working around FAA facilities and potential environmental hazards will be identified and addressed in the Risk Mitigation Plan prior to the start of demolition. The work schedule is contingent upon FAA review and coordination.

Asbestos Survey: Demo of a FAA VOR Facility,

36.884322 – 119.825140, Madera, CA S54-26

BUILDING DESCRIPTION

An asbestos survey was performed on April 13, 2026, at 36.884322 – 119.825140, Fresno, CA. The building is approximately 30-40 years old and approximately 396sqft.

It has a wood frame, Fiberglass siding and roof. The interior walls and ceilings are wood and texture / coating and fiberglass. The floor is wood covered with floor tile and carpet.

Also there is wood and metal roof screen that surrounds the building.

At the time of the survey the building was unmanned FAA VOR Facility.

ASBESTOS ANALYSIS RESULTS

All bulk samples of suspect asbestos containing materials were taken in accordance with US EPA Guidelines and accepted industry standards by a state certified asbestos consultant. McCall and Spero Environmental, Inc., a NVLAP accredited laboratory performed a total of 19 analyses from 18 samples collected from this structure at this site. The samples listed on the table below were negative for asbestos. The full list of all samples taken is on the following pages. Sample locations are indicated on the drawings included with this report.

COMMENTS AND RECOMMENDATIONS

All samples of suspect materials from this site were negative for asbestos.

CONCLUSIONS AND REGULATIONS

US EPA NESHAP (40 CFR Part 61)

Based on our survey, sampling and subsequent laboratory analysis and regulatory guidelines affecting this site, the types of ACM identified on the previous page require removal (in most cases) prior to demolition and/or renovation procedures to comply with local, state and federal agencies. The US EPA NESHAP (40 CFR Part 61 – November 20, 1990) requires materials containing greater than one percent asbestos be removed prior to renovation or demolition. If those materials are friable or likely to become friable due to the forces expected to act upon them during renovation or demolition, they become a regulated asbestos containing material (RACM) and require a 10-day notification to the local Air Pollution Control District prior to abatement.

Non-friable and non-regulated ACM, in most cases, may be disposed of as a Non- Hazardous waste in a landfill that accepts Asbestos Containing Materials. All friable waste containing more than 1% asbestos (RACM) must be manifested as hazardous waste for disposal purposes.

CAL OSHA--------Construction Industry--------8CCR, 1529

Cal/OSHA worker health and safety regulations apply during any disturbance of ACM by a person while in the employ of another. This is true regardless of friability or quantity disturbed. If there is greater than 100 square feet of ACM which will be affected by the demolition, a California Licensed Contractor who is registered with Cal/OSHA for asbestos is required. The regulations regarding asbestos are found in Title 8 CCR Section 1529, and also include formal notification requirements to Cal/OSHA at least 24 hours prior to removal. It is required that removal be conducted with the material kept in a wetted state to contain dust and hazardous emissions.

The construction industry standard covers employees engaged in demolition and construction, and the following related activities likely to involve asbestos exposure:

removal, encapsulation, alteration, repair, maintenance, insulation, spill emergency cleanup, transportation, disposal and storage of ACM.

Demolition contractors typically require that a building owner/operator accept responsibility for removal of all ACM found during the building inspection prior to start of demolition activities.

LIMITATIONS OF LIABILITY

Conclusions and recommendations presented in this report are qualitative judgments based on the prevailing regulations and accepted industry standards at the time of the report issuance. Leon Environmental Services provides no other guarantees, either expressed or implied. All quantities of materials listed herein are estimates for sampling purposes only, and should be verified by Owner representative or an abatement contractor prior to asbestos abatement.

The nature of demolition and asbestos abatement is such that materials can be uncovered which previously were unknown to exist. Therefore, Leon Environmental Services cannot be responsible for materials not previously detected due to lack of accessibility or concealment, although every effort was made during the inspection to detect all suspect materials. If any materials other than those included herein are discovered during renovation or demolition, it must be assumed that the materials are asbestos containing, and should be treated accordingly until further testing and analysis is performed.

The data interpretations and recommendations are based solely on information available to Leon Environmental Services at the time of our inspection. The customer recognizes that site conditions or accessibility may vary, from those encountered at the time of our inspection and sample collection. Varying conditions or access could result in additional information that would lead us to revise conclusions and recommendations. Leon Environmental Services will not be responsible for the interpretation or use by others of information contained within this report.
