Mercury Thermostat Collection Act of 2008 Fact Sheet
Fact Sheet, June 2009
Thermostats are used in heating, ventilation and air conditioning (HVAC) devices and in temperature controls for heat pumps. On January 1, 2006, the State of California banned the sale of new mercury-added thermostats. California’s Mercury Thermostat Collection Act of 2008, Assembly Bill 2347 (Ruskin), requires manufacturers to establish a collection and recycling program for out-of-service mercury-added thermostats, either individually or with other manufacturers. This law provides a convenient, cost-free opportunity for consumers, contractors, and technicians to collect, recycle, and ensure the safe and environmentally-sound management of mercury-added thermostats. Read the complete text of AB2347.
Examples of mercury-added thermostats:
Other styles may vary.
Why is it important to collect and recycle mercury-added thermostats?
In the past, thermostats contained the hazardous metal mercury. Mercury that is released into the atmosphere can be transported long distances and deposited in aquatic ecosystems, where it can be converted into methylmercury, an especially toxic form. Methylmercury can accumulate in fish and humans.
Who must comply with this law?
The Mercury Thermostat Collection Act of 2008 requires manufacturers to establish a collection and recycling program. The bill defines “manufacturer” as “a business concern that owns or owned a name brand of mercury-added thermostats sold in this state before January 1, 2006.”
What are the requirements of this law?
The requirements for all who are affected by the new law can be found on the California Department of Toxic Substances Control (DTSC) Web site.
DTSC lists requirements for manufacturers, wholesalers, retailers and contractors.
How will DTSC determine if the law is working?
Beginning July 1, 2009, and every January 1 and July 1 thereafter, DTSC is required to post on its Web site a list of all manufacturers that fail to comply with this law.
On or before April 1, 2010, and annually thereafter, DTSC will receive an annual report from the manufacturer covering the one-year period ending December 31 of the previous calendar year. The report will include all of the following:
- The number of out-of-service mercury-added thermostats collected in California during the previous calendar year.
- The estimated total amount of mercury contained in the collected out-of-service mercury added thermostats.
- From April 1, 2013, onward, a comparison to the performance requirements for collection established according to regulations developed.
What can I do to collect thermostats and ensure they are properly recycled?
Mercury thermostats are regulated as universal waste in California, which means collecting, consolidating, and transporting them is subject to simple rules.
- A local government that operates a household hazardous waste collection program can obtain a free collection bin from thermostat manufacturers.
- A wholesaler of HVAC equipment can also obtain a collection bin from manufacturers for a nominal $25 fee.
- Contractors, service technicians and demolishers can contact appropriate collection center.
- See a listing of Household Hazardous Waste Collection Facilities sorted by city.
