* TRI release data are for NEG only. There are no TRI releases associated with Utility operations.
** Values for 2000 TRI release data corrected from 2001 Environmental Annual Report.
*** 77.3% of the increase in PCB waste less than 50 parts per million is due to one-time events in 2002, as follows: 53% is from the Decoto pipeyard clean-up; 13.3% is from a one-time disposal of electric transformer bushings; 11% is from large spills including PCB materials.
**** 99.8% of this total is from one major clean up project at the Decoto pipeyard in Union City California. Total without the one-time cleanup is 98,059 Kg.
***** In March, 2001, an expanded definition of "universal waste" went into effect in the California. Due to this broader definition of "universal waste," more of PG&E's waste that was formerly regulated as "California hazardous waste" is now regulated as "universal waste." This regulatory change accounts for the large percent increase in "universal waste" between 2000 and 2002.
