SITE SURVEY SUMMARY SHEET FOR REDDING ARMY AIR FIELD SHASTA COUNTY, CALIFORNIA DERP-FUDS SITE NO. J09CA091500 SITE NAME: Redding Army Air Field LOCATION: The site is located in the southeast section of the Redding city limits, approximately 7 miles from downtown Redding. (Figure 1 and Figure 2). SITE HISTORY: Redding Army Air Field was established in 1942, when the War Department acquired 1,120 lease acres fiom the city of Redding and 320 fee acres from three private owners for a total of 1,440 acres. The Redding Army Air Field was an auxiliary airbase to Chico Army Airfield. Improvements to the site included: buildings, taxiways, a tiedown and heling area for "ready" status aircraft, radio navigation and weather station, aircraft maintenance facilities, a swimming pool, a softball field, roads, and base housing. The site was used extensively for training, as well as a primary point of defense. On 14 December 1946 the site was transferred to the War Assets Administration. Currently the City of Redding the Pacific Gas and Electric Company occupy 1,393.00 acres of the site and the U.S. Forest Service occupies the remaining 47.00 acres SITE VISIT: On 19 and 20 July 1991, Randi Beuttler and Rick Swartz of Radian Corporation visited the site and met with Mr. Juan Orinda of Grounds Maintenance, Mr. Doyle C. Ruff, Director of Airports, and Mr. Rod Dinger, Airports Operations Manager. Mr. Burt Train of Redding Air Service and Mr. Bill Frost of the U.S. Forest Service were also interviewed. Mr. Train has been a pilot in the local area since the 1940's, and Mr. Frost since the 1960s. The site is currently known as Redding Municipal Airport, and is operated by the city of Redding as a general and commercial aviation airport. One building, currently the Northstar Aviation Service hangar, remains from the Army Airbase. This building was originally the aircraft maintenance facility and is located to the north of the air traffic control tower on the west side of Runway 34. The remainder of the Airbase was located on the east side of the runway. The asphalt taxiway, revetments, tiedowns, and heling bunkers are still present. Mr. Train stated that each revetment consisted of an individual heling station for one aircraft; he said he believed fuel was stored below-ground in tanks that were located in the concrete bunkers at each revetment. He also said he believed each of these heling station tanks were approximately 10,000 gallons in size. Three underground storage tanks (USTs) located on the west side of the runway have been abandoned or removed. An additional UST is located on the west side of Runway 34 south of the Northstar hangar; Mr. Train stated that the UST had been used by Pacific Airlines in the 1950s. Concrete building pads are present approximately 1,000 feet east of Runway 34 at midfield. Mr. Orinda stated that most of the Airbase housing was located in this area. The swimming pool is

SITE SURVEY SUMMARY SHEET FOR REDDING ARMY AIR FIELD SHASTA COUNTY, CALIFORNIA DERP-FUDS SITE NO. J09CA091500 located in this area, and is filled with debris including: tires, 55-gallon drums, and brush. Mr. Orinda stated that the debris had been dumped into the swimming pool by a former motorcross'operator. For this reason, the swimming pool is not eligible for the FUDS program. A second site visit was performed on 10 August 1995 by Barbara Blair and Nicola Holmes of the Sacramento District. Three as-built drawings were obtained, before the site visit, fiom the USACE Cadastral section and were used to tour the site (Figures 3,4, 5). Accompanying the Corp personnel on the tour of the site were Glenn Dennis (Airport Maintenance for 12 years) and Leon Perreult (Shasta County Environmental Health Division). Mr. Perreult did not have any reports of tank leaks attributable to tanks installed by the military. Hardstand (HS) No. 1 and 2 have been completely removed along with the 3-8,100 gallon UST's associated with HS #2. Mr. Train stated that 2-10,000 gallon UST's are located at HS #3 and have been used by American Propellar Service which is located adjacent to HS #3. Mr. Dennis stated that the heling pit box associated with HS #3 has been covered with dirt for safety reasons. Piping was observed laying on the ground around HS #4 that Mr Dennis said had been ripped out of the ground by the local farmer. The piping was found approximately 3 feet down. Figure 4 shows 3-8,100 gallon tanks located at HS #5. There are a total of 16 hardstands indicated on the maps. A total of fourteen UST'S are shown on figures 3,4, and 5. In most instances one group of tanks services three hardstands. A pipe locator was used in the areas the map indicated UST's, present. The results of the site survey are as shown in Table 1. Many fill pipes were observed in the vicinity the maps showed a tank present indicating that the tanks were most likely not removed. According to Mr. Dennis, the former base transformers have been used by the airport or by private operators. The old base housing area is used by a motorcross operator who has hooked his intercom system up to the existing power supply that includes the transformers located in this area. Several foundations and concrete piers were found of the former base housing and no evidence of vent pipes were found at these foundations. Three wells are shown on figures 3, 4 ,and 5 (the as-built maps). Two of the wells are located in the housing area and were found during the site visit. They are approximately 12 inches in diameter with an 1 foot, approximate, high concrete base. Well #3 was adjacent to HS #1 and was removed with the hardstand. The motor pool area is located north of the housing area and adjacent to it was a grease pit.

Areas of soil contamination concern include a grease pit that is indicated on the map adjacent to the motor pool area, a cess pool located in the housing area, the septic tank area located on the eastern side of the housing area, and areas the maps indicate a dust pallative. We drove by the former bomb storage area, and Mr. Dennis stated that the airport has pushed a lot of dirt around and no ordnance has been found. The former trap range was visited. The wooden remains of what appears to be the former trap houses were observed. Old looking small arms casings as well as recent small arms casings were found in the shooting range area that is shown as a semi-circle on the map. CATEGORY OF HAZARDS: CON/HTW, HTRW, OE. PROJECT DESCRIPTION: There are three potential projects identified at this site: 1. CON/HTW -- There are 3 known UST's at 2 different sites and 9 suspected underground
,

storage tanks at 3 different sites. The tanks are in the vicinity of the aircraft revetments and at the airbase housing area. Pipe locator readings were not definitive at 3 of the 5 sites because of surface debris or soil mounds. Potholing is to be perfbrmed at these three suspected areas and if tanks are found they are to be removed along with associated piping. Fueling pit boxes are also located at many of the hardstands - 9 total. They are concrete aboveground boxes approximately 5 feet by 3 feet and 1 foot deep. These pits are to be demolished and removed. 2. HTRW -- Areas of soil contamination concern include a grease pit that is indicated on the map adjacent to the motor pool area, a cess pool located in the housing area, and the septic tank area located on the eastern side of the housing area. Also an archives search should be performed to determine the type of dust mitigation that was used during the military's presence and whether it would be considered a hazard today. 3. OEW -- As an active ready-status airfield for area defense, this airfield would have had a firing
range and bunkers for the fighter aircraft. Locations of the bomb storage bunkers are indicated on the as-built maps. AVAILABLE STUDIES AND REPORTS:

DEFENSE ENVIRONMENTAL RESTORATION PROGRAM FORMERLY USED DEFENSE SITES FINDINGS AND DETERMINATION OF ELIGIBILITY WDDING ARMY AIR FIELD SHASTA COUNTY, CALIPORNIA SITE NO. J09CA091500 FINDINGS OF FACT 1. Between 1942 and 1943, the United States of America acquired fee title to 320.0 acres by 3 Declarations of Taking and also a lesehold interest to 1,120.0 acres, by lease, for a total of 1,440.0 acres of land. In 1944, the USA also acquired, by Quitclaim Deed title to a right-of-way in Tract #1. 2. The site was located in'the southeastern section of the city of Redding in Shasta County, California. It has also been referred to as Municipal Airport or Redding Shasta Airport. The site was acquired for use by the Army Air Force as an army Air Field and later used .only for emergency landings of aircraft. Improvements to the site included: buildings, a hospital, taxiways, a tiedown and heling area for "ready" status aircraft, radio navigation and weather reporting buildings and equipment, aircrafl maintenance facilities, a swimming pool, a softball field, roads, and base housing. The site was used for training, and also as a point of defense. 3. On 14 December 1946 the site was transferred to the War Assets Administration. The City of Redding and the Pacific Gas And Electric Company currently occupy 1,393.00 acres while the remaining 47.0 acres of land is occupied by the U.S. Forest Service. The quitclaim deed contained a clause releasing the federal government from liability for restoration or damage. The quitclaim deed also contained a recapture provision. The majority of the site is currently known as Redding Municipal Airport, and is currently used as a general and commercial aviation airport.
Based on the foregoing findings of the site has been determined to be formerly used by the DOD. Therefore, it is eligible for the Defense Restoration Program for Formerly Used Defense Sites, established under 10 U.S.C. 2701 et seq.

PROJECT SUMMARY SHEET FOR DERP-FUDS CONIHTRW PROJECT NO. J09CA91501 REDDING ARMY AIRFIELD SITE NO. J09CA0091500 PROJECT DESCRIPTION: According to as-built maps of the Redding Airfield, there are a total six areas where UST's were located. Three tanks located adjacent to HS #2 were removed four years ago. A pipe locator failed to pick up conclusive readings at three of the sites due to surface debris or mounds of soil. However, the pipe locator did have positve readings for the two sites numbered T170 ( 2- 8,900 gal UST's) and T23 (500 gal UST) and these three tanks are to be removed along with associated piping. The maps accurately matched the physical locations of the tanks. A total of 3 wells are shown on the maps. HS #1 and the Well No. 3 adjacent to it have both been removed. Two wells remain in the housing area and were observed during the second site visit: Well No. 1 and Well No.2. The wells have a diameter of approximately 1 foot and are encased in a square foundation of concrete that is about 1 foot high. A total of 9 fbeling pits are located on the site. Each is approximately 5 feet by 3 feet by 1 foot deep.
PROJECT ELIGIBILITY: The known and suspected storage tanks east of Runway 34 were installed and used solely by the Army. The wells were installed by the Army for the base housing and were used solely by the Army. POLICY CONSXDERATIONS: The DOD installed UST's west of Runway 34 are in use and are therefore not eligible for the DEW-FUDS program. PROPOSED PROJECT: There are 3 known UST's at 2 different sites and 9 suspected underground storage tanks at 3 different sites. All the tanks are in the vicinity of the aircraft revetments and at the airbase housing area. Pipe locator readings were not definitive at 3 of the 5 sites because of surface debris or soil mounds. Potholing is to be performed at these three suspected areas: T155: 3-8,100 gal UST's T163: 3-8,100 gal UST's T166: 2-8,900 gal UST's If tanks are found they are to be removed along with associated piping and soil testing is

This risk assessment procedure was developed in accordance with MILSTD 882C and AR 385-10. The Risk Assessment Code (RAC) score will be used by the U.S. Army Engineering and Support Center, Huntsville (USAESCH), Ordnance and Explosives Team (USAESCH-OE) to prioritize the remedial action(s) at Formerly Used Defense Sites (FUDS). The risk assessment should be based on the best available information resulting from records searches, reports of Explosive Ordnance Disposal (EOD) detachment actions, field observations, interviews, and measurements. This information is used to assess the risk involved based on the potential OE hazards identified at the site. The risk assessment is composed of two factors, hazard severity and hazard probability. Personnel involved in visits to potential OE sites should view the USAESCH-OE videotape entitled "A Life Threatening Encounter: OEW." Part I. Hazard Severity.
