(03/22/07 -- SAN FRANCSICO) Industries operating in California reduced toxic releases by 4 percent in 2005 compared to 2004, according to the latest data available from the U.S. Environmental Protection Agency.

The data comes from the EPA’s Toxics Release Inventory, an annual measure of toxic chemical releases, transfers and waste generated by facilities in the United States. Total releases include toxic chemicals discharged to air, water, underground injection, land –including landfills – and the amount transferred off-site for disposal. Data provided does not mean that facilities with elevated levels are out of compliance with state, local or federal environmental regulations.

“TRI is an important tool for regulators, emergency responders, businesses and communities because it helps them better understand and be aware of the types and amounts of chemicals being released in their neighborhoods,” said Wayne Nastri, the EPA’s administrator for the Pacific Southwest region. “We are pleased to report a decrease in the amount of toxic chemicals released in California in 2005.”

In California, 1,513 facilities reported a total of 46.3 million pounds of toxic chemical releases. This is 1.9 millions pounds less than was released in 2004, a reduction of 4 percent.

Leading the downturn was a decrease in air releases by 6 percent, or a total of 1.2 million pounds.

On-site land releases went down by 3 percent, or 487,000 pounds.

Underground injection releases decreased nearly 4,000 pounds, a 17 percent reduction.

California saw a reported decrease in water releases as well. Water releases decreased 758,000 pounds, an 18 percent drop.

The reporting of data to the Toxics Release Inventory is required under the federal Emergency Planning and Community Right-to-Know Act, passed in 1986. This program has been credited with arming communities with valuable knowledge and encouraging facilities to reduce their releases of toxic chemicals into the environment through source reduction, or pollution prevention measures.

In 2000, the Toxics Release Inventory expanded to include Persistent Bioaccumulative and Toxic chemicals, or PBTs, and to require reporting for these chemicals at ranges from 0.1 grams to 100 pounds.

PBT pollutants are toxic chemicals that persist in the environment and bioaccumulate in food chains, posing risks to human health and ecosystems. In California, 5 million pounds of total on-site and off-site releases of PBT chemicals were reported. This is a decrease of 10 percent or 545 thousand pounds from the previous year. A decrease in lead and lead compound releases drove down the overall decrease of PBT releases in the state.

The top ten facilities in California for total on-site and off-site releases of all chemicals are:

1. Chemical Waste Management Inc. (Kettleman City, Kings County) with 10.9 million pounds.
2. Tesoro Refining & Marketing Co (Martinez, Contra Costa County) with 2.5 million pounds.
