Frustrated with delays in Sacramento, Bay Area officials said Thursday they planned to take matters into their own hands to regulate the region’s growing pile of electronic trash.
A San Jose councilwoman and a San Francisco supervisor said they would propose local initiatives aimed at controlling electronic waste if the California law-making body fails to act on two bills stalled in the Assembly. They are among a growing number of California cities and counties that have expressed the same intention.
Environmentalists and local governments are increasingly concerned about the toxic hazard posed by old electronic devices and the cost of safely recycling those products. An estimated 6 million televisions and computers are stocked in California homes, and an additional 6,000 to 7,000 computers become outdated every day. The machines contain high levels of lead and other hazardous substances, and are already banned from California landfills (垃圾填埋场).

A. Exert pressure on manufacturers of electronic devices.
B. Lay down relevant local regulations themselves.
C. Lobby the lawmakers of the California Assembly.
D. Rally support to pass the stalled bills.
