2.0 Executive SummaryCurrent Use of Property

The subject site consists of one former aircraft hanger and approximately 22 remnant concretefoundations/slabs identified as former barracks, offices and workshops/storage facilities located on thenorthern and eastern portions of the subject site. The western and southern portions of the subjectsite are undeveloped native desert land with scattered to dense native vegetation. The subject existingand former buildings occupy approximately 3 percent of the property.

Database/Records Review

Atwell retained EDR of Milford, Connecticut, to review federal, tribal, state and EDR proprietaryrecords related to the subject site and nearby properties within the ASTM approximate minimumsearch radius (as seen on the table below). However, Atwell typically reviews local, state, tribal orfederal database records of those sites of known environmental contamination (i.e., SHWS, LUST,CERCLIS, and NPL sites) within a one-quarter mile radius of the subject site. Atwell considers siteswithin this specified search radius as having the most potential to impact the subject site. Also, Atwelltypically reviews local, state, tribal or federal database records of those sites of suspectedenvironmental contamination (i.e., UST, Indian UST and RCRA generator sites), which adjoin thesubject site, or, in the professional opinion of Atwell, are of such nature and proximity to the subjectsite to represent RECs.

EDR did not identify any sites of known or suspect contamination located within one-quarter mile ofthe subject site. The EDR Radius Report with GeoChecklist Report is included in Appendix G.

Historical/Document Review

Based on information gathered during the site investigation, review of aerial photographs, review ofhistorical address indexes, and review of municipal records, Atwell concluded that the subject site waslikely undeveloped prior to development and use as a pilot training facility from approximately 1940 to1945. First as a glider pilot training (circa 1940 to 1942) (Arizona Gliding Academy) and then withpowered aircraft (circa 1942 to 1945) (Claiborne Flight Academy) for the United States Army AirForce during World War II. The military reportedly turned the airport over to civil control at the end ofWorld War II. Information reviewed from several websites on abandon airports report that the site wasalso used as a prison and to house migrant workers (no dates available) after the war. The Userquestionnaire also indicated that the site was used as a mine supply area and for film production (nodates). The subject site reportedly was used as the Wickenburg Municipal Airport from 1958 to 1962. The site has reportedly been abandoned since the late 1960s/1970s. The subject site has also beenoperated/identified under several different names during its history. Originally called WickenburgField/Echeverria Field in the 1940s it has also been known as the Wickenburg Airport, or theForepaugh Airport/Air Field. Several of the buildings have reportedly been destroyed by firesincluding some of the barracks.

Site Reconnaissance Findings

During the site reconnaissance, Atwell evaluated the subject site for the potential presence of thefollowing Recognized Environmental Conditions: (1) hazardous substances; (2) petroleum products;(3) evidence of the presence of underground storage tanks (USTs); (4) evidence of the presence ofaboveground storage tanks (ASTs); (5) other suspect containers; (6) polychlorinated biphenyl(PCB)-containing equipment; (7) interior or exterior staining/corrosion; (8) discharge features (i.e.,current or former septic/leaching fields, floor drains, oil/water separators); (9) pits, ponds or lagoons;(10) evidence of excavation and/or landfilling activities; (11) evidence of surface soil/surface waterstains and/or stressed vegetation; (12) water supply and/or groundwater monitoring wells, and (13)

2.0 Executive Summary (continued)Site Reconnaissance Findings (continued)

observations of adjacent property uses and potential evidence of adverse environmental impactsassociated with adjoining properties. During the site reconnaissance, Atwell observed the following items and potenital RECs: Atwell evaluated the subject site for the possible presence of USTs. Typical indicators of USTsinclude: (1) gas pumps or pump islands; (2) vent pipes; (3) fill ports; or (4) unusual depressions.During the site reconnaissance, Atwell observed an approximately 25,000 gallon concrete septic tank inthe north west portion of the site and numerous pieces of clay pipe identified as the possible formerdrain field. The septic tank had approximately 1 foot of sludge and 4 feet of water in the tank. Atwelldid not observe any readily apparent evidence of the current/former presence of petroleum/chemicalUSTs at the subject site. The lack of visible evidence of any potential USTs and the fact that the individuals and agenciesidentified in this report were not aware of or did not have record of the presence of any USTs does notpreclude the possibility that USTs could be present at the subject site property. Visible evidence ofUSTs, such as fill ports or vent pipes, may have been obscured from view and USTs could have beenused at the subject site property without the knowledge of the current owner/operator, site contact orgovernment agency. Evidence of two ASTs were observed on the subject property during the site reconnaissance. BothAST's were empty and not in service at the time of the site reconnaissance. Details of the ASTs areprovided below. Atwell observed several 55-gallon steel drums and 5-gallon metal containers scattered throughout thenorthern portion of the subject site including in the northwest corner in the vicinity of the landdisturbances observed in the 1948 and 1951 aerial photographs. The drums and containers were inpoor condition (heavily rusted) with holes and dents. No product labels were observed or readable onany of the drums or containers. One empty 55-gallon drum labeled as a Quaker State drum but noproduct label was observed. No other suspect containers were identified on the subject property duringthe site reconnaissance. Atwell inspected the subject site for the presence of oil-cooled electrical equipment that may containPCBs. Atwell did not observe any readily apparent evidence for suspect PCB-containing equipmentlocated on the subject site. During the site reconnaissance, Atwell observed staining and etching on several of the concreteslabs/foundations during the site reconnaissance. The observed stains included paint, rust andunknown chemical(s).

It is the opinion of the EP that potential impact to the subsurface environment from historical leaks andspills of unknown chemicals including petroleum products and/or hazardous materials represents anREC to the subject site. During the site reconnaissance Atwell observed a septic tank and associated drain field and manholes,one floor drain and two catch basins for concrete pads (wash pads?) and a manhole with water present. Atwell observed one large pit and several smaller excavations in the northern portion of the subject siteduring the site reconnaissance. The large pit approximately 1000 to 1500 feet square andapproximately 8 to 10 feet deep had some debris including wood (lumber) fragments, metal pieces withthree soil stockpiles located south and east of the pit. Several smaller excavations were also observedin the northern portion of the site. These smaller excavations had debris including glass, metal, (cans,equipment), wood (lumber), charred debris, and other solid waste and appeared to have been partiallybackfilled. No staining was observed in any of the excavations or associated soil stockpiles.

2.0 Executive Summary (continued)Site Reconnaissance Findings (continued)

During the site reconnaissance Atwell observed several areas with evidence of solid waste dumping,debris piles, soil/asphalt stockpiles on the subject property. Atwell observed one water supply well on the subject property during the site reconnaissance. Thewell is located just south of the northern property line in a former building. Building has been removedleaving the concrete slab and the well head. A 2-inch water supply line is present just south of the wellhead.

Other Environmental Considerations

During the site reconnaissance, Atwell did not observe any evidence (i.e., cases of cold tablets, dietpills, several containers of solvents) for the presence of controlled substances on the subject site.

During the site reconnaissance and review of reasonably ascertainable records, Atwell did not identifyany situations suggestive of continuing environmental obligations (i.e., institutional limitations,engineering controls). The scope of services for this Phase I ESA did not include: (1) an evaluation for the presence of suspectasbestos-containing materials; (2) an evaluation of the presence of lead-based paint on the subject site;(3) an evaluation for the potential presence of Radon in the area of the subject site; (4) an evaluation ofsuspect wetland areas on the subject site; (5) a mold evaluation; (6) an evaluation of items ofnon-compliance with applicable local, state, or federal regulations, and (7) addressing anyclient-specific items for the subject site. The following are several business environmental considerations that are beyond the scope of astandard ASTM or most AAI Phase I ESAs that can be addressed on a client-specific or lender-specificbasis. The scope of services for this Phase I ESA did not include addressing any client-specific items for thesubject site. The scope of services for this Phase I ESA did not include an evaluation of items of non-compliancewith applicable local, state, or federal regulations. The scope of services for this Phase I ESA did not include addressing any client-specific items for thesubject site.

Findings and Opinions

During the course of this Phase I ESA, Atwell identified and evaluated several potential environmentalconcerns and it is the opinion of the EP that no RECs have been identified for the subject site orassociated with nearby properties. OR During the course of this Phase I ESA, Atwell identified andevaluated several potential environmental concerns and it is the opinion of the EP that the followingRECs have been identified for the subject site and/or associated with nearby properties. During the course of this Phase I ESA, Atwell identified and evaluated the following known or suspectRECs associated with the subject site or nearby properties: • Slab #14 located to the east of the barrack complex appears to have been a building used for

material and chemical storage and possibly equipment/vehicle maintenance and repair. Numerous stains (brown to black) are present on the concrete slab on the western portion ofthe slab. These stains are associated with what appear to be impressions/rust stains from

2.0 Executive Summary (continued)Findings and Opinions (continued)

55-gallon drums and other containers. Also the main floor of the building is dark brown withred areas also with container rings and paint stains present. Further, there is anapproximately 4 ft X 4 ft opening in the concrete slab with an approximately 3 ft diameterplastic/non metal vertical pipe in the opening. On the south side of the slab are twoapproximately 15 feet wide by 150 feet long concrete bermed areas with several very faint55-gallon drum marks in the concrete. The southern area shows evidence of an approximately1 foot wide trench having been excavated and backfilled (with concrete). There is also two2-inch PVC pipes just south of the 4 ft X 4 ft opening. Based on the observed evidence thisformer building appears to have been used for material and chemical storage and likely use ofmaterials and chemicals. No information is available regarding what chemicals may havebeen used or stored at the facility. However, based on the EP's experience and the history ofthe subject site (used as a pilot training facility with aircraft), it is likely that chemicalsincluded petroleum products including fuels, lubrication oils, cleaning solvent (petroleum andhalogenated based), and other hazardous and non-hazardous chemicals used to maintain theaircraft and support vehicles and equipment. The staining of the concrete indicates that spillsand releases occurred during the facility operations. It is the opinion of the EP that thesestains and likely historical use of the building represent a suspect REC and additionalassessment work is recommended.

• Pad # 3 is located to the west of the barrack complex and consists of a concrete slab with

remnant wall and a ramp. The northern portion of the slab appears to have had a small shedor other structure with at least one 55-gallon drum in the shed. Stains outline the base of aformer drum. The contents of the former 55-gallon drum are unknown. It is the opinion ofthe EP that the presence of the staining and the unknown history of the former buildingrepresent a potential REC and additional assessment work is recommended.

• The hanger building is the only building currently remaining on the subject site. The building

is in very poor condition with significant damage to the walls and roof areas. The concretefloor has two openings. One approximately 20-inch floor drain on the south side of the floor,and one approximately 3 ft X 15 ft opening on the northwest side of the floor. Both openingsare filled with dirt. The history of the hanger building is unknown but is likely to haveincluded aircraft servicing and repair. Several small stains were observed on the floor whichis partially covered by dirt and cow manure. Approximately 3 feet southwest of the hanger isa covered concrete manhole with liquid (water) present approximately 1 foot below the top ofthe concrete pipe. It is unknown where the manhole discharges and whether it is connected tothe on-site wastewater system. Based on the historical use of the building as a hanger likelyconducting servicing and repair of aircraft and equipment using various hazardous andnon-hazardous chemicals including petroleum products (fuels, oils and lubricants) andcleaning solvents, it is the opinion of the EP that the hanger represents a potential REC andadditional assessment work is recommended.

• Slab # 3 is located north of the Hanger building and consists of a concrete slab with remnant

walls surrounded by debris from the former building. The concrete slab is partially coveredby the debris and very faint suspect staining was observed on the exposed concrete. Thisbuilding appears to have burned (partially) and the debris from the building left in place. Thehistorical use of the building is unknown. However, due to the close proximity of this buildingwith the Hanger and asphalt paved ramps on the east side of the slab it is likely that thisbuilding was historically used to service/maintain equipment, aircraft, vehicles or used to storematerials and possibly chemicals used to maintain the facility equipment. It is the opinion ofthe EP that the presence of the staining and the unknown history of the former buildingrepresent a potential REC and additional assessment work is recommended.

• Two wash pads were observed on the site. One associated with the hanger and one located tothe south of Slab #8. These concrete pad were sloped to the center of the pad. The southernpad has a 20-inch square opening (former drain) at the center. The pad associated with thehanger is mostly covered by up to 6 inches of dirt and the center portion is not visible butbased on the slope of the exposed concrete is likely present at the center. The exposed concreteon the southern pad is heavily etched and very faint discolorations (staining?) were observed issome areas. The pads have been identified as wash pads likely for equipment, aircraft andvehicles. The use of and type of chemicals that may have been used historically is unknown. Based on EP experience with other similar facilities and wash pads it is likely that cleaningsolvents and petroleum products (fuel, oils lubricants) were used. It is the opinion of the EPthat the presence of the staining and the unknown history of the former pads represent apotential REC and additional assessment work is recommended.

• During the site reconnaissance numerous debris piles were observed throughout the northern

portion of the subject site. These debris piles appeared to be debris associated with the formerbuildings. The debris generally consisted of wood (lumber), stucco/plaster, metal (equipment,pipes, pieces, food cans, 5-gallon containers), clothing, glass, broken ceramics (toilets) andother solid waste. It is the opinion of the EP that based on the age of some of the buildingsasbestos may have been used in the buildings. Atwell recommends that debris associated withor containing building materials be tested for the presence of asbestos to evaluate the need toabate any identified asbestos containing building material.

• During the historical aerial review the northwest corner of the site appeared disturbed

(excavation/landfilling?). During the site reconnaissance the northwest corner was observedto have solid waste including metal food cans, ceramic pieces (toilets), wood and other debrisburied and partially buried. It is the opinion of the EP that the presence of the dump area withunknown historical disposal practices and materials represents a potential REC andadditional assessment work is recommended.

• One large pit and several smaller pits were observed during the site reconnaissance. The large

pit appeared to have been partially backfilled with wood (lumber) and metal pieces observedpartially buried in the bottom. The historical use of this pit is unknown and based on thepresence of metal and wood debris may have been a dump/solid waste disposal area. It is theopinion of the EP that the unknown historical use and the presence of solid waste that the pitmay represent a potential REC and additional assessment work is recommended.

• The subject site used an on-site wastewater treatment system for sewage disposal. The septic

tank was located to the northwest of the barrack complex approximately 400 to 450 feet withunderground piping connecting the former buildings to the septic tank through severalmanholes located at the corners of some of the buildings. While no odors were observed in theseptic tank water and sludge the facility has not operated for over 50 years and runoff mayhave wash any potential chemicals out of the tank and into the drain field. The drain field islikely to the west of the tank in an area with numerous broken clay pipes on the surface overan apparently disturbed area. The septic system was likely connected to the barracks andoffices, as well as the three or four buildings that appear to have stored and/or used chemicalsused to service and repair the various equipment, aircraft and vehicles on the subject site. Itis unlikely that discharges from the barracks and offices contained hazardous chemicals orpetroleum products, however, the three or four buildings that did apparently use or storethese chemicals could have the potential to have discharged these unknown chemicals andpetroleum products to the sewer system and eventually to the septic tank and drain field. It isthe opinion of the EP that there is a potential for historical discharges of unknown chemicalsand/or petroleum products to the on-site wastewater treatment facility and impacts to thesubsurface. Based on the potential for impacts to the subsurface additional assessment workis recommended for the on-site wastewater treatment system.

• During the aerial review and the site reconnaissance Atwell identified an area of soil staining

along the southern edge of the subject site that appears to be associated with theadjacent property to the south (residence/ranch). The soil staining has a very faint petroleumodor as well as an organic (manure) odor. Based on the pattern observed from the aerialphotographs it appears that runoff is migrating from the south adjacent property on to thesubject site. The area that the runoff appears to come from was observed to contain amaintenance shop, stored farm equipment (backhoe, tractor) and several plasticdrum containing oil/lubricants. The area is also used by a small herd of cattle. It is the opinionof the EP that the stained soil may represent a potential offsite impact to the subject site and isconsidered a potential REC.

Atwell has performed this Phase I ESA in general conformance with the scope and limitations ofASTM Practice E1527-05 and AAI specifications for the subject site located at N. 436th Avenue andUS Highway 60, Maricopa County, Arizona. During the course of this Phase I ESA, the EP identifiedRECs associated with the subject site as previously identified. Therefore, Atwell recommends that a Phase II Subsurface Investigation be conducted to determine the nature, extent and materiality of theidentified potential RECs. Atwell was provided a "Final Site Cleanup and Remediation at Forepaugh Airfield, Wickenburg,Arizona" letter report prepared by Parsons Engineering Services, Inc. (PES) prepared for the Town ofWickenburg (TOW) dated April 4, 1995. The letter report indicated that four 55-gallon drums withcadmium contaminated soils from Waste Pile GS-10 and the ore hopper and furnace were transportedoffsite to Beatty, Nevada for hazardous waste disposal. The report also reported that 62 tons of"non-toxic" contaminated soils (contamination not listed), contents of 55-gallon drums and other sitesoils were disposed of at Butterfield Landfill in Mobile, Arizona. PES reported that confirmation soilsamples were collected and analyzed from beneath the Waste Pile GS-10 for compliance withregulatory cleanup levels. While the analytical results and information presented in the PES April 4,1995 report indicated that the areas of interest had been remediated the letter report did not include anysite maps/figures depicting the location(s) of any excavations, soil sampling, drums and ore hopper andfurnace. It is the opinion of the EP that it is possible that the remedial actions conducted by PES in1994/1995 may have included one or more potential RECs listed in Section 10.1. However, withoutinformation on location(s) of any excavations, soil samples, drums, leaching ponds, Waste Pile GS-10,ore hopper or ore furnace, it is the opinion of the EP that the listed potential RECs need to beaddressed. If additional information is provided that depicts the remediation areas, sampling locationsAtwell will review the provided information and modify the potential RECs as necessary.

3.0 Introduction3.1 Purpose

Atwell conducted the Phase I Environmental Site Assessment (ESA) in order to provide anindependent, professional opinion of the possible presence of Recognized Environmental Conditions(RECs) or other possible environmental concerns (if any) associated with the subject site as part ofenvironmental due diligence. As defined in American Society for Testing and Materials (ASTM)Designation: E 1527-05, the term Recognized Environmental Conditions means "...the presence orlikely presence of any hazardous substances or petroleum products on a property under conditions thatindicate an existing release, a past release, or a material threat of a release of any hazardous substancesor petroleum products into structures on the property or into the ground, groundwater, or surface waterof the property".

Performance of the Phase I ESA was intended to reduce, but not eliminate, uncertainty regarding theexistence of Recognized Environmental Conditions in connection with the subject site.

3.2 Scope of Work

Atwell performed the Phase I ESA while using standards typically adhered to by other environmentalconsulting professionals. Atwell adheres to such professional standards in an effort to maintaininnocent landowner defense options for sellers, bona fide prospective purchasers, lenders and/orcontiguous property owners under guidelines set forth in the Federal Comprehensive EnvironmentalResponse, Compensation, and Liability Act (CERCLA). The Phase I ESA was performed to meet thestandard of "All Appropriate Inquiry" (AAI) as promulgated by the United States EnvironmentalProtection Agency (USEPA) to qualify for the CERCLA innocent landowner defenses.

The Phase I ESA was conducted in general conformance with the ASTM Designation: E 1527-05,Standard Practice For Conducting Environmental Site Assessments and 40 Code of FederalRegulations (CFR) Part 312, AAI [AND BANK GUIDELINES, IF APPLICABLE].

This Phase I ESA was performed to evaluate environmental risk and does not include any investigationinvolving business environmental risks.

The Scope of Work for the Phase I ESA included: • A visual inspection of the subject site on May 5, 2011, and all improvements thereon to evaluate

general environmental conditions; • Establishing the present and past land uses at and adjacent to the site through the review of: (1)

historical aerial photographs; (2) city directories; (3) the local topographic map; (4) localAssessment/Building Department/Tax records; (5) historical Sanborn Fire Insurance Maps, ifavailable; (6) the local Fire Department, and (7) interviews with present and past owners, operatorsand/or occupants, when available;

• A review and evaluation of the following databases of federal, tribal, state, and local known or

suspected sites of environmental contamination within the applicable ASTM recommended distancefrom the subject site, including but not limited to: (1) The United States Environmental ProtectionAgency's (USEPA's) National Priority List (NPL) records including, current NPL sites, proposedNPL sites, de-listed NPL sites and NPL recovery (Superfund Liens) sites; (2) TheUSEPA's Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) listof known or suspected hazardous waste sites; (3) The USEPA's Comprehensive EnvironmentalResponse, Compensation and Liability Information System (CERCLIS)-No Further RemedialAction Planned (NFRAP) list of known or suspected hazardous waste sites; (4) The USEPA'sResource Conservation Recovery Act (RCRA) Corrective Action Report (CORRACTS) list forfacilities that produce small quantities, large quantities, or transport, store, or dispose (TSD) ofhazardous materials that are subject to corrective action under RCRA; (5) The USEPA's Resource

• Atwell has also provided a list of references used to complete the project (Appendix A).

The Phase I ESA was conducted between the period of April 21, 2011 to June 1, 2011.

This Phase I ESA was completed by Keith Ross, RG, Environmental Specialist and EnvironmentalProfessional (EP) of Atwell, under the supervision of Rich Petrus, Team Leader and EP. The EP'sinvolvement includes the project planning; supervision; reviewing and interpreting all data collected;formation of findings and opinions; report review, and recommendations for any further investigations,if warranted. Personnel resumes are included in Appendix B.

3.3 Significant Assumptions

During the course of this Phase I ESA, no significant assumptions were made.

3.4 Limitations and Exceptions

Atwell has concluded that aerial photograph data failure occurred prior to 1948 and between theyears 1951 and 1981. No Sanborn maps were identified for this site and City Directories did not listany addresses for the subject site. Some areas of the site are covered by dense vegetation which limitsvisual observations. In addition, many of the remnant concrete building slabs and foundations arecovered by debris preventing visual observation of the concrete foundations/slabs for staining, pipes orother potential information. These gaps, conditions or absences of information represent data failure inrecords pertaining to the subject site.

The information obtained from external sources, to the extent it was relied upon to form Atwell'sopinion about the environmental condition of the site, was assumed to be complete and correct. Atwellcannot be responsible for the quality and content of information from these sources. However, based ona review of readily available and reasonably ascertainable information, Atwell concluded that theselimitations/data gaps should not materially limit the reliability of the report and that a thoroughdocumentation of the subject site's environmental condition has been conducted.

6.0 Records Review6.1 Standard Environmental Records Sources

Atwell retained EDR of Milford, Connecticut, to review federal, tribal, state and EDR proprietaryrecords related to the subject site and nearby properties within the ASTM approximate minimumsearch radius (as seen on the table below). However, Atwell typically reviews local, state, tribal orfederal database records of those sites of known environmental contamination (i.e., SHWS, LUST,CERCLIS, and NPL sites) within a one-quarter mile radius of the subject site. Atwell considers siteswithin this specified search radius as having the most potential to impact the subject site. Also, Atwelltypically reviews local, state, tribal or federal database records of those sites of suspectedenvironmental contamination (i.e., UST, Indian UST and RCRA generator sites), which adjoin thesubject site, or, in the professional opinion of Atwell, are of such nature and proximity to the subjectsite to represent RECs.

EDR did not identify any sites of known or suspect contamination located within one-quarter mile ofthe subject site. The EDR Radius Report with GeoChecklist Report is included in Appendix G.

6.0 Records Review (continued)6.2 Additional Environmental Record Sources

Atwell reviewed current and historical files maintained by the Maricopa County offices for the subjectsite. The review of municipal records was conducted in order to identify possible environmentalconcerns (e.g., suspect building materials, USTs, ASTs, etc.) associated with the subject site. AssessingDepartment records indicate that there are no environmental records available for the subject site. Inaddition, Atwell requested any commonly known information from the assessing/building departmentrepresentatives. According to the Assessor's Office website the only information available indicatesthat commercial yard maintenance was conducted in 1998. Interview documentation is included inAppendix I. Records documentation is included in Appendix H.

Atwell contacted the Maricopa County offices to determine the zoning specifications for the subjectsite. The subject property is currently zoned IND-1 and IND-2 which is Light Industrial and RU-43which is Residential.

Atwell contacted the Town of Wickenburg Fire Department (TOWFD)for information regardingcurrent or former USTs or ASTs at the subject site, as well as, any hazardous material storage, spillresponse records or commonly known information that may be available from fire departmentrepresentatives. The TOWFD has not responded to the request in time for this report. Interviewdocumentation is included in Appendix I. Records documentation is included in Appendix H.

The subject site is not currently connected to any municipal or public utilities. Electric service isavailable through Arizona Public Service. Water was supplied through a onsite supply well and sewerwas treated via an onsite septic system. Natural gas (butane) was reportedly used onsite during the1940s probably for heating systems. Atwell reviewed the Arizona Department of Water Resourcesregistered well database for information on the on-site supply well. Records documentation is includedin Appendix H.

The Maricopa County Environmental Services Department (MCESD) maintain environmental files forsites throughout Maricopa County. The files contain field inspection reports from city inspectors,reported environmental problems, results of right-to-know programs and other miscellaneous data.Atwell submitted a FOIA request to the MCESD for any information regarding water wells, septicsystems, hazardous material storage or any commonly known information that may be available fromMCESD representatives. Ms. Jeanne Taylor of the MCESD indicated that there were no environmentalrecords available for the subject site. Atwell also submitted a FOIA to the MCESD Onsite WasterWater Program for septic system records. Atwell has not received a response as of the date of thisreport on septic system records. MCESD documentation is included in Appendix H. AND/ORInterview documentation is included in Appendix I. Atwell submitted a facility records review request with the Arizona Department of EnvironmentalQuality for additional information on the reported remediation conducted from November 1994 toMarch 1995. ADEQ Records Section has not provided Atwell with a date to review any records in timefor this report.

6.3 Physical Setting Sources

Atwell reviewed the USGS 7.5 Minute Topographic Map of the subject site and surrounding area. Thetopographic map reviewed was the 1990 Forepaugh Peak, Arizona Quadrangle. Surface drainage at thesubject site appears to be generally to the northwest, towards unnamed dry washes. According to theEDR, Physical Setting Source Summary, no groundwater flow direction data has been reported withinone mile of the subject site. Unless otherwise noted, the surface drainage flow direction has beeninferred from a review of regional topographical data. Site-specific conditions may vary due to avariety of factors, including geologic anomalies, utilities, nearby pumping wells (if present), and otherdevelopments.

6.4 Historical Use Information6.4.1 Historical Summary

Based on information gathered during the site investigation, review of aerial photographs, review ofhistorical address indexes, and review of municipal records, Atwell concluded that the subject site waslikely undeveloped prior to development and use as a pilot training facility from approximately 1940 to1945. First as a glider pilot training (circa 1940 to 1942) (Arizona Gliding Academy) and then withpowered aircraft (circa 1942 to 1945) (Claiborne Flight Academy) for the United States Army AirForce during World War II. The military reportedly turned the airport over to civil control at the end ofWorld War II. Information reviewed from several websites on abandon airports report that the site wasalso used as a prison and to house migrant workers (no dates available) after the war. The Userquestionnaire also indicated that the site was used as a mine supply area and for film production (nodates). The subject site reportedly was used as the Wickenburg Municipal Airport from 1958 to 1962. The site has reportedly been abandoned since the late 1960s/1970s. The subject site has also beenoperated/identified under several different names during its history. Originally called WickenburgField/Echeverria Field in the 1940s it has also been known as the Wickenburg Airport, or theForepaugh Airport/Air Field. Several of the buildings have reportedly been destroyed by firesincluding some of the barracks.

6.4.2 City Directories

Atwell retained EDR to conduct a review of historical cross-index directories (i.e., Cole Criss-CrossDirectory) on file for the subject site and immediately adjoining properties. Cole Criss' Cross-IndexDirectories compile historical addresses for sites located throughout central Arizona. EDR reviewedthe Cole Criss-Cross Directory for the Maricopa County area indexes in approximately five-year

intervals for the time period between 1965 to 2008. During the review of historical address directories,Atwell did not identify any occupants of environmental concern located on or adjacent to the subjectsite. Therefore, it is the opinion of the EP that city directories have not identified any RECs associatedwith the subject site or adjacent properties.

The following is a listing of the specific directories utilized and the occupants located at and adjacent tothe subject site:

6.4.3 Aerial Photos

Atwell reviewed aerial photographs for the years 1948, 1951, 1981, 1985, 1992, 1997, 2001, 2006 and2010 on file with EDR and the Maricopa Assessor's Office. Aerial photographs are included inAppendix F. Atwell observed an area in the northwest corner of the subject site that appears to evidence ofdisturbance (excavation) and in the southwest corner of parcel 506-20-007 that has been disturbed.

No other evidence of landfilling activities, waste dumping, unexplained excavation, or hazardousmaterial storage activities were observed during the review of historical aerial photographs.

The aerial photograph review is as follows:

6.4.4 Sanborn/Historical Maps

Atwell submitted a request to EDR for copies of available Sanborn Fire Insurance Maps that cover thesubject site and surrounding adjacent properties. These historical maps may provide informationpertaining to adverse land uses and the presence and/or location of USTs. EDR concluded thatSanborn/Fire Insurance Maps were not available for the subject site. The Sanborn Map No Coveragereceipt is included in Appendix F.

6.4.5 Other Environmental Reports

FindingsThe report summarized the June 1995 field activities of remediating and disposal of 4 piles of miningwaste located on the BLM land at the Forepaugh Airport. The report indicated that the waste piles wereeast of the subject site on the adjacent land that contained the former airstrip. According to the summaryreport, approximately 291 tons of mining waste that had leachable levels of lead, arsenic, and cadmiumwere stabilized on-site by mixing with cement and water then transported to Butterfield Station SubtitleD landfill for disposal after curing. Four clearance samples (composite) were collected (one from eachformer waste pile location) that indicated that the metals were below regulatory action levels.

7.0 Site Reconnaissance7.1 Methodology and Limiting Conditions

On May 5, 2011 Keith Ross, Environmental Specialist III for Atwell, conducted a walkingreconnaissance of the subject site. During the site reconnaissance, Atwell evaluated the subject site forthe potential presence of the following Recognized Environmental Conditions: (1) hazardoussubstances; (2) petroleum products; (3) evidence of the presence of underground storage tanks (USTs);(4) evidence of the presence of aboveground storage tanks (ASTs); (5) other suspect containers; (6)polychlorinated biphenyl (PCB)-containing equipment; (7) interior or exterior staining/corrosion; (8)discharge features (i.e., current or former septic/leaching fields, floor drains, oil/water separators); (9)pits, ponds or lagoons; (10) evidence of excavation and/or landfilling activities; (11) evidence ofsurface soil/surface water stains and/or stressed vegetation; (12) water supply and/or groundwatermonitoring wells, and (13) observations of adjacent property uses and potential evidence of adverseenvironmental impacts associated with adjoining properties (addressed in Section 4.5).

The weather condition at the time of the site reconnaissance was sunny and hot. The visualreconnaissance consisted of observing the boundaries of the property and systematically traversing thesite to provide an overlapping field of view, wherever possible. The periphery of the on-site structureswere observed along with interior accessible areas. The subject site is covered by vegetation rangingfrom scattered to dense. In some areas the vegetation prevented visual and physical observations. Alsoat the time of the site reconnaissance two bee hives and a wasp nest were observed in the northern wall

of the hanger building which limited access to the northwest corner of the hanger floor. In addition,many of the remnant concrete slabs are covered by debris limiting visual observation of the condition(stains, pipes, etc) of the concrete slab. Photographs of pertinent site features identified during the sitereconnaissance are included in Appendix D.

7.2 General Site Setting

During the site reconnaissance, Atwell observed the subject site to be comprised of approximately 80acres of predominately undeveloped land with remnant buildings located north of the intersection ofUS Highway 60 and N. 436th Avenue, Maricopa County, Arizona. The subject site consists ofone former hanger building and approximately 22 concrete slabs/foundations and associated wash pads,septic system and numerous soil/debris piles. The majority of the remnant buildings and features arelocated in the northeastern portion of the subject site with the south and west portionsbeing undeveloped land with scattered to dense native desert vegetation.

The Site Inspection Environmental Checklist is included in Appendix J.

7.0 Site Reconnaissance (continued)7.3 Site Visit Findings (continued)

7.3.3 USTs (continued)

The lack of visible evidence of any potential USTs and the fact that the individuals and agenciesidentified in this report were not aware of or did not have record of the presence of any USTs does notpreclude the possibility that USTs could be present at the subject site property. Visible evidence ofUSTs, such as fill ports or vent pipes, may have been obscured from view and USTs could have beenused at the subject site property without the knowledge of the current owner/operator, site contact orgovernment agency.

7.3.4 ASTs

Evidence of two ASTs were observed on the subject property during the site reconnaissance. BothAST's were empty and not in service at the time of the site reconnaissance. Details of the ASTs areprovided below.

any of the drums or containers. One empty 55-gallon drum labeled as a Quaker State drum but noproduct label was observed. No other suspect containers were identified on the subject property duringthe site reconnaissance.

7.3.6 Equipment Likely to Contain PCBs

Atwell inspected the subject site for the presence of oil-cooled electrical equipment that may containPCBs. Atwell did not observe any readily apparent evidence for suspect PCB-containing equipmentlocated on the subject site.

7.3.7 Staining/Corrosion

During the site reconnaissance, Atwell observed staining and etching on several of the concreteslabs/foundations during the site reconnaissance. The observed stains included paint, rust andunknown chemical(s).

It is the opinion of the EP that potential impact to the subsurface environment from historical leaks andspills of unknown chemicals including petroleum products and/or hazardous materials represents anREC to the subject site.

8.0 Interviews

With the exception of previously mentioned interviews and/or information received from theClient, owner, occupants and/or municipal offices, no other interviews were conducted during thecourse of this Phase I ESA.

9.0 Other Environmental Considerations9.1 Controlled Substances

The presence of controlled substances on the subject site must be evaluated if the client is applying foror has been awarded a grant under CERCLA/EPA or if the property is considered abandoned. The term "controlled substance" means a drug or other substance, or immediate precursor, included inschedule I, II, III, IV, or V of part B of 21 US Code 802. The drugs include but are not limited toephedrine and pseudoephedrine, which are suppressants that are used in common over-the-counterweight control and decongestant drugs, as well as, acetone, toluene and other solvents. These"controlled substances" are used to manufacture various drugs for recreational use. Unusually largequantities (i.e., cases of cold tablets, diet pills, unexplained containers of solvents) would be observedif the substances were being misused and site use should be taken into account when evaluating for"controlled substances". The term does not include distilled spirits, wine, malt beverages, or tobacco, asthose terms are defined or used in subtitle E of the Internal Revenue Code of 1986. During the site reconnaissance, Atwell did not observe any evidence for the presence of controlledsubstances on the subject site.

9.2 Continuing Obligations

Owners or operators of real property may be subject to certain land use restrictions or institutionalcontrols as part of continued occupancy of a site. These obligations may include resource restrictions;conducting reasonable steps with respect to hazardous substance releases; provide full cooperation,assistance, and access to persons that are authorized to conduct response actions or natural resourcerestorations; comply with federal information requests and administrative subpoenas, and provide all

9.0 Other Environmental Considerations (continued)9.2 Continuing Obligations (continued)

legally required notices. During the site reconnaissance and review of reasonably ascertainablerecords, Atwell did not identify any situations suggestive of continuing environmental obligations (i.e.,institutional limitations, engineering controls).

9.3 Asbestos-Containing Materials

The scope of services for this Phase I ESA did not include an inspection or sampling of suspect ACMs.

9.4 Lead-Based Paint

The scope of services for this Phase I ESA did not include an evaluation of the presence of lead-basedpaint on the subject site.

9.5 Radon

9.6 Wetlands

The scope of services for this Phase I ESA did not include an evaluation of suspect wetland areas onthe subject site.

9.7 Mold Evaluation

The scope of services for this Phase I ESA did not include a mold evaluation on the subject site.

9.8 Items of Non-Compliance

The scope of services for this Phase I ESA did not include an evaluation of items of non-compliancewith applicable local, state, or federal regulations.

9.9 Client-Specific Items

The scope of services for this Phase I ESA did not include addressing any client-specific items for thesubject site.

10.0 Phase I Findings/Opinions/Conclusions10.1 Report Findings and Opinions

During the course of this Phase I ESA, Atwell identified and evaluated the following known or suspectRECs associated with the subject site or nearby properties: • Slab #14 located to the east of the barrack complex appears to have been a building used for

material and chemical storage and possibly equipment/vehicle maintenance and repair. Numerous stains (brown to black) are present on the concrete slab on the western portion ofthe slab. These stains are associated with what appear to be impressions/rust stains from55-gallon drums and other containers. Also the main floor of the building is dark brown withred areas also with container rings and paint stains present. Further, there is an

Atwell, LLC

10.0 Phase I Findings/Opinions/Conclusions (continued)10.1 Report Findings and Opinions (continued)

approximately 4 ft X 4 ft opening in the concrete slab with an approximately 3 ft diameterplastic/non metal vertical pipe in the opening. On the south side of the slab are twoapproximately 15 feet wide by 150 feet long concrete bermed areas with several very faint55-gallon drum marks in the concrete. The southern area shows evidence of an approximately1 foot wide trench having been excavated and backfilled (with concrete). There is also two2-inch PVC pipes just south of the 4 ft X 4 ft opening. Based on the observed evidence thisformer building appears to have been used for material and chemical storage and likely use ofmaterials and chemicals. No information is available regarding what chemicals may havebeen used or stored at the facility. However, based on the EP's experience and the history ofthe subject site (used as a pilot training facility with aircraft), it is likely that chemicalsincluded petroleum products including fuels, lubrication oils, cleaning solvent (petroleum andhalogenated based), and other hazardous and non-hazardous chemicals used to maintain theaircraft and support vehicles and equipment. The staining of the concrete indicates that spillsand releases occurred during the facility operations. It is the opinion of the EP that thesestains and likely historical use of the building represent a suspect REC and additionalassessment work is recommended.

• Pad # 3 is located to the west of the barrack complex and consists of a concrete slab with

remnant wall and a ramp. The northern portion of the slab appears to have had a small shedor other structure with at least one 55-gallon drum in the shed. Stains outline the base of aformer drum. The contents of the former 55-gallon drum are unknown. It is the opinion ofthe EP that the presence of the staining and the unknown history of the former buildingrepresent a potential REC and additional assessment work is recommended.

• The hanger building is the only building currently remaining on the subject site. The building

is in very poor condition with significant damage to the walls and roof areas. The concretefloor has two openings. One approximately 20-inch floor drain on the south side of the floor,and one approximately 3 ft X 15 ft opening on the northwest side of the floor. Both openingsare filled with dirt. The history of the hanger building is unknown but is likely to haveincluded aircraft servicing and repair. Several small stains were observed on the floor whichis partially covered by dirt and cow manure. Approximately 3 feet southwest of the hanger isa covered concrete manhole with liquid (water) present approximately 1 foot below the top ofthe concrete pipe. It is unknown where the manhole discharges and whether it is connected tothe on-site wastewater system. Based on the historical use of the building as a hanger likelyconducting servicing and repair of aircraft and equipment using various hazardous andnon-hazardous chemicals including petroleum products (fuels, oils and lubricants) andcleaning solvents, it is the opinion of the EP that the hanger represents a potential REC andadditional assessment work is recommended.

• Slab # 3 is located north of the Hanger building and consists of a concrete slab with remnant

walls surrounded by debris from the former building. The concrete slab is partially coveredby the debris and very faint suspect staining was observed on the exposed concrete. Thisbuilding appears to have burned (partially) and the debris from the building left in place. Thehistorical use of the building is unknown. However, due to the close proximity of this buildingwith the Hanger and asphalt paved ramps on the east side of the slab it is likely that thisbuilding was historically used to service/maintain equipment, aircraft, vehicles or used to storematerials and possibly chemicals used to maintain the facility equipment. It is the opinion ofthe EP that the presence of the staining and the unknown history of the former buildingrepresent a potential REC and additional assessment work is recommended.

• Two wash pads were observed on the site. One associated with the hanger and one located to

the south of Slab #8. These concrete pad were sloped to the center of the pad. The southernpad has a 20-inch square opening (former drain) at the center. The pad associated with the

Page 33 of 210




hanger is mostly covered by up to 6 inches of dirt and the center portion is not visible butbased on the slope of the exposed concrete is likely present at the center. The exposed concreteon the southern pad is heavily etched and very faint discolorations (staining?) were observed issome areas. The pads have been identified as wash pads likely for equipment, aircraft andvehicles. The use of and type of chemicals that may have been used historically is unknown. Based on EP experience with other similar facilities and wash pads it is likely that cleaningsolvents and petroleum products (fuel, oils lubricants) were used. It is the opinion of the EPthat the presence of the staining and the unknown history of the former pads represent apotential REC and additional assessment work is recommended.

• During the site reconnaissance numerous debris piles were observed throughout the northern

portion of the subject site. These debris piles appeared to be debris associated with the formerbuildings. The debris generally consisted of wood (lumber), stucco/plaster, metal (equipment,pipes, pieces, food cans, 5-gallon containers), clothing, glass, broken ceramics (toilets) andother solid waste. It is the opinion of the EP that based on the age of some of the buildingsasbestos may have been used in the buildings. Atwell recommends that debris associated withor containing building materials be tested for the presence of asbestos to evaluate the need toabate any identified asbestos containing building material.

• During the historical aerial review the northwest corner of the site appeared disturbed

(excavation/landfilling?). During the site reconnaissance the northwest corner was observedto have solid waste including metal food cans, ceramic pieces (toilets), wood and other debrisburied and partially buried. It is the opinion of the EP that the presence of the dump area withunknown historical disposal practices and materials represents a potential REC andadditional assessment work is recommended.

• One large pit and several smaller pits were observed during the site reconnaissance. The large

pit appeared to have been partially backfilled with wood (lumber) and metal pieces observedpartially buried in the bottom. The historical use of this pit is unknown and based on thepresence of metal and wood debris may have been a dump/solid waste disposal area. It is theopinion of the EP that the unknown historical use and the presence of solid waste that the pitmay represent a potential REC and additional assessment work is recommended.

• The subject site used an on-site wastewater treatment system for sewage disposal. The septic

tank was located to the northwest of the barrack complex approximately 400 to 450 feet withunderground piping connecting the former buildings to the septic tank through severalmanholes located at the corners of some of the buildings. While no odors were observed in theseptic tank water and sludge the facility has not operated for over 50 years and runoff mayhave wash any potential chemicals out of the tank and into the drain field. The drain field islikely to the west of the tank in an area with numerous broken clay pipes on the surface overan apparently disturbed area. The septic system was likely connected to the barracks andoffices, as well as the three or four buildings that appear to have stored and/or used chemicalsused to service and repair the various equipment, aircraft and vehicles on the subject site. Itis unlikely that discharges from the barracks and offices contained hazardous chemicals orpetroleum products, however, the three or four buildings that did apparently use or storethese chemicals could have the potential to have discharged these unknown chemicals andpetroleum products to the sewer system and eventually to the septic tank and drain field. It isthe opinion of the EP that there is a potential for historical discharges of unknown chemicalsand/or petroleum products to the on-site wastewater treatment facility and impacts to thesubsurface. Based on the potential for impacts to the subsurface additional assessment workis recommended for the on-site wastewater treatment system.

• During the aerial review and the site reconnaissance Atwell identified an area of soil stainingalong the southern edge of the subject site that appears to be associated with theadjacent property to the south (residence/ranch). The soil staining has a very faint petroleumodor as well as an organic (manure) odor. Based on the pattern observed from the aerialphotographs it appears that runoff is migrating from the south adjacent property on to thesubject site. The area that the runoff appears to come from was observed to contain amaintenance shop, stored farm equipment (backhoe, tractor) and several plasticdrum containing oil/lubricants. The area is also used by a small herd of cattle. It is the opinionof the EP that the stained soil may represent a potential offsite impact to the subject site and isconsidered a potential REC. Additional assessment work is recommended for the stainedarea.

10.2 Conclusions

Atwell has performed this Phase I ESA in general conformance with the scope and limitations ofASTM Practice E1527-05 and AAI specifications for the subject site located at N. 436th Avenue andUS Highway 60, Maricopa County, Arizona. Any exceptions to, or deletions from, this practice aredescribed in Section 3.4 of this report. During the course of this Phase I ESA, the EP identified RECsassociated with the subject site as previously identified. Therefore, Atwell recommends that a Phase IISubsurface Investigation be conducted to determine the nature, extent and materiality of the identifiedpotential RECs. Atwell was provided a "Final Site Cleanup and Remediation at Forepaugh Airfield, Wickenburg,Arizona" letter report prepared by Parsons Engineering Services, Inc. (PES) prepared for the Town ofWickenburg (TOW) dated April 4, 1995. The letter report indicated that four 55-gallon drums withcadmium contaminated soils from Waste Pile GS-10 and the ore hopper and furnace were transportedoffsite to Beatty, Nevada for hazardous waste disposal. The report also reported that 62 tons of"non-toxic" contaminated soils (contamination not listed), contents of 55-gallon drums and other sitesoils were disposed of at Butterfield Landfill in Mobile, Arizona. PES reported that confirmation soilsamples were collected and analyzed from beneath the Waste Pile GS-10 for compliance withregulatory cleanup levels. While the analytical results and information presented in the PES April 4,1995 report indicated that the areas of interest had been remediated the letter report did not include anysite maps/figures depicting the location(s) of any excavations, soil sampling, drums and ore hopper andfurnace. It is the opinion of the EP that it is possible that the remedial actions conducted by PES in1994/1995 may have included one or more potential RECs listed in Section 10.1. However, withoutinformation on location(s) of any excavations, soil samples, drums, leaching ponds, Waste Pile GS-10,ore hopper or ore furnace, it is the opinion of the EP that the listed potential RECs need to beaddressed. If additional information is provided that depicts the remediation areas, sampling locationsAtwell will review the provided information and modify the potential RECs as necessary.

DELISTED NPL: National Priority List DeletionsThe National Oil and Hazardous Substances Pollution Contingency Plan (NCP) establishes the criteria that theEPA uses to delete sites from the NPL. In accordance with 40 CFR 300.425.(e), sites may be deleted from theNPL where no further response is appropriate.




CERCLIS: Comprehensive Environmental Response, Compensation, and Liability Information SystemCERCLIS contains data on 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 which are either proposed to or on the National PrioritiesList (NPL) and sites which are in the screening and assessment phase for possible inclusion on the NPL.

CERCLIS-NFRAP: CERCLIS No Further Remedial Action PlannedArchived sites are sites that have been removed and archived from the inventory of CERCLIS sites. Archived statusindicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determinedno further steps will be taken to list this site on the National Priorities List (NPL), unless information indicatesthis decision was not appropriate or other considerations require a recommendation for listing at a later time.This decision does not necessarily mean that there is no hazard associated with a given site; it only means that,based upon available information, the location is not judged to be a potential NPL site.

Manufactured Gas Plants: EDR Proprietary Manufactured Gas PlantsThe EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants)compiled by EDR’s researchers. Manufactured gas sites were used in the United States from the 1800’s to 1950’sto produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixtureof coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production,such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compoundsare potentially hazardous to human health and the environment. The byproduct from this process was frequentlydisposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soiland groundwater contamination.

Echeverria Field From Wikipedia, the free encyclopedia

Echeverria Field is an abandoned airfield, located approximately 15 miles (24 km) west of Wickenburg, Arizona.

History

Built by the United States Army Air Forces, Activated on 3 June 1942 as Wickenburg Field. Runway consisted of 4,000' NE/SW main (04/22) and 3,200' NW/SE (13/29). Main runway extended to 4,500' during 1943. Both runways were asphalt surfaced.

Initially used by 5th Glider Training detachment for unpowered gilder training. Primary use was basic flying training of flight cadets under contract to Claiborne Flight Academy. Flying training was performed with Fairchild PT-19s as the primary trainer. Also had several PT-17 Stearmans and a few P-40 Warhawks assigned. Had one satellite airfield located near Aguila, AZ.

Inactivated on 19 April 1944 with the drawdown of AAFTC's pilot training program. The airfield was turned over to civil control at the end of the war though the War Assets Administration (WAA). Was used by various private entities after the war, including being a prison & housing migrant workers. Wickenburg was used at some point between 1958-62 as a municipal airport for Wickenburg until a new facility was built closer to town.

Today the facility is abandoned. The main runway appears to have been extended after the war, secondary barley visible in aerial photography. Derelict hangar and a minor structure still standing, however some concrete building foundations is all that remain of the airport/airfield ground station and a street pattern in derelict condition.

Echeverria Field / Wickenburg Airport / Forepaugh Airport (44E), Wickenburg, AZ

33.95 North / 113 West (Northwest of Phoenix, AZ)

"Wickenburg" was depicted as an auxiliary airfield on the February 1943 Phoenix Sectional Chart (courtesy of Chris Kennedy).

This small airfield (located in between the towns of Forepaugh & Wickenburg)

has gone through a somewhat confusing succession of names through the years.

Echeverria Field started out in 1940 as a AAF contract glider pilot school during WW2,

operated by the Arizona Gliding Academy & the Claiborne Flight Academy.

According to the book "Best Place in the Country" by Mike Hoza & Steve Hoza,

the Claiborne Flight Academy was owned by Harry Claiborne,

and began training pilots in 1942.

According to Brian Rehwinkel, the Claiborne Flight Academy had an auxiliary field used for to support flight training operations,

located approximately 10 miles west of the parent field, near Aguila, AZ [of which no trace apparently remains].

In 1943, glider training ended at the Claiborne Flight Academy, and a primary flight training school began operation, for powered aircraft.

"Wickenburg" was depicted as an auxiliary airfield

on the 1943 Phoenix Sectional Chart (courtesy of Chris Kennedy).

To confuse matters somewhat, the separate "(Municipal) Wickenburg" Airport was also depicted several miles to the east,

adjacent to the northwest side of the town of Wickenburg.

According to Gary Anderson, “My father (Tom Anderson) was the chief flight instructor at this field before he went overseas.”



The name of the field was changed to "Echeverria"

on the March 1945 Phoenix Sectional Chart (courtesy of Chris Kennedy).

The 1945 AAF Airfield Directory (courtesy of Scott Murdock) described Echeverria Field

as a 1,440 acre square property having 2 asphalt runways (4,000' northeast./southwest & 3,200' northwest/southeast)

and a 2,300' square landing mat at the runway intersection.

The field was said to not have any hangars,

to be owned by the State of Arizona, and to be operated by the Defense Plant Corporation.

Brian Rehwinkel reported, “I found an article in a 1948 Prescott Evening Courier that indicated the 'large hangar' at the field

(which I believe to be the same Echeverria Field) burned on February 10, 1948.

There is yet another name used for the airport - The Hassayampa Flying Service Airport.”

It was labeled "Wickenburg" Airport once again on the 1949 Gila River World Aeronautical Chart (courtesy of Donald Felton),

and described as having a 4,500' hard-surface runway.

Military use of the airfield ended in 1950.

In the post-WW2 era it went on to a number of uses including being a prison & housing migrant workers.



The earliest photo which has been located of Echeverria Field is a 1951 US Government aerial view (courtesy of Brian Rehwinkel).

Brian observed, it “shows the field after the war… when if was probably not used very much.

However, you can see the pavement very well – and I am not sure if the runway outlines were postwar markings, or if they were left over from the field’s training days.

You can also see the buildings in the cantonment/administration area.

If you notice, there is a dark rectangular spot on the aircraft parking apron next to the buildings (on the north side of the apron).

That spot is apparently the location of a former aircraft hangar.”

Echeverria Field was not depicted at all on the 1956 Prescott Sectional Chart (courtesy of John Voss)

or the 1958 Phoenix Sectional Chart (according to Chris Kennedy).

Wickenburg was reused at some point between 1958-62

as the municipal airport for the town of Wickenburg (located 17 miles east)

until a new field was built closer to town.

It was listed among active airports in the 1962 AOPA Airport Directory,



with a single clay runway.

The field was depicted as "Wickenburg" Airport on the 1969 USGS topo map,

but only as "Landing Strip" on the 1980 & 1990 USGS topo maps.

No public-use airfield at the location was listed in the 1989 Airport/Facility Directory (courtesy of Chris Kennedy).

As seen in the 1997 USGS aerial photo, the airfield consists of a 6,000' unpaved Runway 3/21,

along with the shorter east/west runway, the remains of which are barely perceptible,

extending into the desert to the east from the southern end of the main runway.

There can also be seen the evidence of an original 2,500' square landing mat area

situated underneath the northeast portion of the main runway,

along with a northwest/southeast runway.

As of the mid-1990s, one of the original barracks buildings was still standing,



but it has since been torn down.

Since then, the only remaining buildings are the main hangar & 2 outlying buildings.

As of 2006, this field is listed as an active public-use airport, under the name of Forepaugh Airport.

Only a 4,700' length of Runway 3/21 was listed as available.

The Civil Air Patrol has proposed building a training facility at the airfield,

plans which would include restoration of some of the airfield's historic buildings.
