Alameda County Waste Management Authority Proposed Fee

The Alameda County Waste Management Authority (also known as StopWaste) is considering adoption a fee of $9.55 per year per residential unit, collected through your property tax roll, to support household hazardous waste collection.  At its meeting on February 26, 2014 at 3:00 p.m. at 1537 Webster St. Oakland, StopWaste will review adoption of this fee.  What is the fee for? Revenue from the fee will be used to support the countywide household hazardous waste program , which provides safe, legal, environmentally sound collection and disposal services for residential household hazardous waste such as paints, solvents, and pesticides.  These services such as those at the West Winton facility in Hayward, that is closest to Castro Valley, will be expanded so that less household hazardous waste ends up in our garbage, recycling, or worse as illegal dumps.  For more on this fee and household hazardous waste in Alameda County, please visit the following website or call 1-877-786-7927.


Recycle Your Leftover Paint & Cans

Recycling your leftover paint in California just got much more convenient!  October 19, 2012 marked the first day of California's Paint Stewardship Program, kicking off with 335 retail collection sitesacross the state.


Castro Valley Sanitary District (CVSan) is pleased to announce that in Castro Valley, there are now two PaintCare locations where paint is accepted during regular store hours only.  There is no fee for dropping off paint at PaintCare locations, and the limit is 5 gallons per visit per day.  

Kelly Moore               3090 Castro Valley Blvd.                510-690-9249

Dunn-Edwards         20923 Redwood Road                    510-881-0313

What’s Accepted: Interior and exterior architectural paint sold in containers of 5 gallons or less will be accepted (latex, acrylic, water-based, oil-based, enamel, deck coatings, primers, sealers, stains, shellacs, lacquers, varnishes, swimming pool paints, metal coatings, and rust preventatives). 

Who Can Participate: Residents, trade painters, contractors, and businesses (that produce less than 27 gallons of hazardous waste per month) are eligible to participate.  Both new and old paint can be dropped off, even if it is over 20 years old.

California’s PaintCare Program is a result of Assembly Bill 1343 (Huffman), passed in 2010.  Leftover paint is a national problem representing 40-60%, by volume, of all Household Hazardous Waste collected at public facilities.  In California, it is estimated that paint management currently costs local governments $21 million each year.  California is the first state in the nation to have a permanent paint stewardship program.

CVSan passed Resolution 3289 on August 7, 2012 in support of Extended Producer Responsibility.
