1. ,, 4, CALIFORNIAi L WATER QUALITYCONTROL BOARD CENTRAL VALLEY REGION 3201 S Street Sacramento, California 95516 Phone: 445-0270 TO: Antonia Vorster Senior• -;:ROM: Jim Eckman Area Engineer DATE: 11 February 1986 SIGNATURE: SUBJECT: DUMPING DRIED RESIN IN HARNEY LANE On 16 January 1986 1 received a call from Aerodynamics, Inc., of Lodi asking for authorization to dump some barrels of dried resin at the Harney Lane Landfill. I called Tom Horton of the San Joaquin County Department of Public Works, who said they would accept the barrels if they were dry and if we agreed. Aerodynamics had brought the barrels to the landfill once before, but they had liquid on top of the dried resin so Mr. Horton wouldn't accept them then. Aerodynamics claimed it was rain water. Mr. Horton wasn't sure. I was in Lodi on 28 January so I stopped to check it out. Aerodynamics makes the fiberglass blades (each 10 feet long) for large windmill generators. They had used barrels of resin but have just switched to bulk resin. The shop is four months• #and looked clean and organized. There .. barrels gallons each) on the asphalt on the east side of the building at 1023 East Vine Street. The top and bottom of each barrel was removed and the top of each was covered with a garbage bag to keep out rain water. The barrels were from 3/4 full to full. I probed the top of the barrels and determined that each was dry. The resin in each was dry and hard. We tipped over two barrels and the resin in the bottom was hard and dry. One of the men used a 6-8 inch long bit and drilled into the top, bottom, and side (three holes each) of one barrel I selectedand did not •moisture.•holes•# ofanother Specialties.barrel were dry. The bit broke in the third hole. Mr. Richard Avalon of Aerodynamics gave me a copy of a 4 November 1985 letter (copy attached) from David Leu of DHS' Alternative Technology section to ECO Chemical *hardened,• resin is a lnonhazardous waste' and can be disposed of in trash cans but that disposal is still subject to our requirements. I verified the letter with its author, Bill Quan. Mr. Avalon said that the resin was put into the barrels a little at a time from buckets as it began to harden. Raw resin is mixed with MEKP (a catalyst) and brushed intothemoldsand fiberglass• • Once a mold is completed, leftover resin is put in the waste resin barrels where it hardens. Mr. Avalon said that no uncatalyzed resin or other chemicals are put in the barrels. ....__.�.... ..--�u-.___...,�..z____„�-�•_-.�..<.._-�..-_.. a--��.,,_,.-.p,., rg., �._..., .,.. ,-..,..._�. _.r �,„,-.:. az.+s,:.+s's` � - a -r �. _ ,.� _ _.� .,.rx z`� ., :
