r 1• CAD982358889 Site Reconnaissance Trinkle & Boys Agricultural Flying Interview and Observation Report (Continued) Service Comments and Observations (continued) 5/14/92 chemicals are mixed in the batcher and transferred to the holding tank before being pumped into the awaiting airplanes. A concrete pad and a sump is located directly south of the chemical holding tank and. hatcher. The concrete pad and sump area serves as a wash down facility where chemicals are'washed from airplanes and equipment. Standing water was observed above the sump grating. Mr.Boys indicated that the electrical sump pump malfunctioned and cannot pump rinse water to the 6,500-gallon capacity holding tank across the landing strip. The pump had been out of operation since April 1992. Trinkle &Boys complied with the Regional Water Quality Control Board's guidelines for installing a rinse water collection system on the facility in 1986, as required for all aerial applicators in the Central Valley. Mr. Boys plans to demolish the present sump system and construct a new double-lined sump system to meet new pesticide rinse water regulations. Airplane engine maintenance is performed on a strip east of the hangar/office. Large oil spots can be seen on the ground surface. According to Mr. Boys;the California Department of Health Services inspected the oil spots and determined no regulations were violated. Spilled oil was hosed off into the sump. Adjacent to the southern hangar is a fenced pesticide storage area. Several pesticides and fungicides are stored in this area. Empty pesticide containers were triple washed and dumped into a trash container before disposal to a Class II landfill. The Department of Agriculture inspects the trash container before being hauled off the site. Dark brown soil stains and white powder trails leading up to the fenced entrance were noted on the ground surface. Spills occurred in this area. Another storage area east of the the hangar/office contained empty stacked 55-gallon drums. This area was fenced. Mr.Boys indicated that these drums were tripled washed prior to .storage. According to Mr. Boys, no wastes are generated on site that contained lead, paints, or parts cleaners. Two underground storage tanks are located on the property. One tank, approximately 100 feet east of the hangar/office once contained aviation gasoline about five to six years ago, but now is empty. Plans are underway to remove this tank under the supervision of the Air Pollution Control District. Aviation gasoline is presently being delivered by a mobile trailer tank. Another underground storage tank is located east of the southern hangar. Four above ground storage tanks can be seen on the east end of the property. Three of the tanks belong to a former gas station,now a`forklift repair shop, located southeast of the Trinkle&Boys site. Apparently, the underground storage tanks of the gas station were removed and are now stored on the property. The fourth tank,located next to the storage area east of the hangarloffice, stored automobile gasoline that was pumped from the gas station's tanks before its removal. A drinking water well is located off site less than 200 feet north of the'hangar/office, This well serves both Trinkle &'Boys and a residential home located north of the site. 'Mr. Boys does not know the depth of the water well. A septic tank is possibly located along the northern side of the site. Gravel rinse basins where planes used to be rinsed were located on either side of the landing strip;however, over the years the gravel has " become more of a conglomerate consisting of soil and gravel. The business possesses an operational permit from the Department of Agriculture. Five people are regularly on the site Page 2 of 2 This report was prepared by: (Signature and Date) EPA PA/S1 SR00012
