Re: Disposition of11azardous Waste at IT Panoche and Vine Hill Facilities This is to confirm the final disposition of specific hazardous wastes shipped to the IT Corporation Panoche (Benicia) and Vine Hill (Martinez) facilities from PG&E's Humboldt Bay Power Plant (HBPP) in July,1986. The information provided herein is on one of three shipments of hazardous waste containing minute quantities of radioactive isotopes to the IT facilities in the 1980's. Prior to the July, 1986 shipment, approval was granted by the Nuclear Regulatory Commission (NRC) and the California State Department of Health Senices, Radiological Health Branch (DHS) to dispose of the wastes as            1 hazardous waste at the Panoche facility.
IT has completed a review of the PG&E shipments and has provided information on the final disposition of the three shipments. The information provided herein is consistent with that provided by IT directly to Ms. Wei Wei Chui on Jamiary 13,1997 (copy enclosed).                                         l The July 1986 shipment (referred to as Shipment 4 in the enclosure) included four loads of wastewater pond sindge and one load of flyash. On April 25,1985 PG&E requested NRC approval to dispose of the waste as hazardous waste at the IT Panoche facility. Approval was granted on September 3,1985 from the NRC. Approval was also granted by the California Department of Health Senices on January 21,1986. The flyash was received at the Panoche facility in July,1986. The sludge was accepted at the Vine Hill facility, where it was accumulated with other commercial waste. Much of the mixed accumulated solids were routinely removed from Vine Hill and transferred to the Panoche facility for final disposal. IT's records indicate that the solids from at least one load have remained at the Vine Hill facility. PG&E assumes that the Vine Hill facility is the final disposition site for any waste that was not transferred to the Panoche facility.
Should you have any questions concerning this information, please contact me at (707) 444-0700.
Sincerely, cA.

Sunnlemental Information Reauests - IT Panoche Facility PG&E Humbolt Bay Power Plant Waste Streams

==Dear Ms. Chui:==

During the public comment period for the draft Environmental Impact Report (EIR) and Closure Plans for the IT Panoche Facility, a question was raised related to certain wastes genemted by the PG&E Humbolt Bay Power Plant. The genesis of these comments was an {{letter dated|date=August 23, 1996|text=August 23,1996 letter}} from PG&E to Mr. Greg Yuhas summarizing waste shipments from Humbolt Bay to the IT Panoche and Vine Hill facilities. Since the close of the public comment period, PG&E has provided clarifying information to DTSC in an {{letter dated|date=October 18, 1996|text=October 18,1996 letter}}, and.to Mr. Yuhas and IT in letters dated October 22,1996. In addition to this information, DTSC has verbally requested IT provide supplemental information rega-ding                     )
waste shipments to the Panoche facility.                                                                                    '
IT has completed a detailed file review of the PG&E shipments and confirmed acceptance and                   .
management procedures for each of;the specific waste shipments sent by PG&E to either the Vine Hill Complex or Panoche facility. In addition to the information provided to DTSC in PG&E's {{letter dated|date=October 18, 1996|text=October 18, 1996 letter}}, the following detail is provided relative to shipments 3,4, and 5.                                             l Shipment 3 - Five loads of sludge from the oil water separator were received at the Panoche facility between August 31 and September 5,1984. This matetial was sent to Panoche due to the                     I metals concentrations and all five loads were accepted into Waste Management Unit (WMU) 17.
N                   Shipment 4 - This shipment included four loads of wastewater treatment pond sludge and one
  \                 load of ash deposits from the firebox at the fossil fuel plant. The wastewater pond sludges were all accepted at IT's Vine Hill Complex. Solids from this waste stream accumulated in the Vine Hill surface impoundments along with numerous other solids associated with commercial waste
                   . receipts. Much of the mixed accumulated solids were routinely removed from Vine Hill and                        1 transferred to the Panoche facility for final disposal in WMUs 17 and 18. The single load of firebox ash was received at the Panoche facility and disposed ofin WMU 17 on July 15, 1986.
Shinment 5 - This shipment was sent from Humbolt Bay to the IT Vine Hill Complex. Solids residues from this load were not sent to Panoche; no wastes were received at Panoche after December 1986.
