>I am a Los Angeles County Solid Waste Inspector and have been assigned to

>By tomorrow.
>Do any of you have such a document already?? If so, could I review it,

>Any help would be appreciated.

>I am glad to see local government is getting into the act on this issue.  I
>am a consultant but I have been researching the persistent herbicides for
>an article, so I have some suggestions.
>I have spoken and corresponded with Dr. Tobi Jones of the Division of
>Registration and Health Evaluation, California Department of Pesticide
>Regulation, (916) 445-3984,, who is working with the
>CIWMB and Dow on this issue.  She told me that picloram, the other
>persistent herbicide that wreaked havoc in Washington, has no registered
>uses in California, so the focus is on clopyralid.
>Most clopyralid probably enters the green waste stream from applications to
>landscape turf.  To my mind, the first question is, how much
>clopyralid-containing product is sold in your region.  This information
>should be available from Dow.  An article on their website,
>, lists the
>numbers of gallons sold in the Spokane area.  Ideally, the information
>would be broken down so you would have a list of the clopyralid-containing
>products and the number of gallons sold in your region.
>When you have that information, you might try working with landscape
>product suppliers to get them to quit selling the products.  If that fails,
>work with UC extension educators and landscape organizations (California
>Landscape Contractor's Assn., Turf and Landscape Council, etc.) to educate
>them to either quit using the products or dispose of treated clippings as
>solid waste.  Of course it would be preferable to get Dow to remove the
>products from the market, and you should try that first. But the solution
>may have to be more grass-roots(!!!)
>There is also the possibility of clopralid entering the compost stream from
>agricultural use of products.  This contamination could affect composts
>made from agricultural wastes, which are typically sold to organic and
>conventional farmers.  Clopyralid is registered for use on mint, beets,
>wheat, asparagus, oats and barley.  Composters typically compost manure, so
>if any of the grain crops are fed to cattle or horses, they would end up in
>the manure. (I believe that is how the compost at WSU was contaminated.)
>  And wheat and oat straw are commonly used in large amounts as a
>carbonaceous composting feedstock to combine with manure.  Also, culls and
>waste products from mint and beet production are typically composted.  If
>any of these commodities are grown in your area, you should work with UC
>extension and grower's associations to get more information, educate, etc.
>If you have contracts with any compost producers, you should do everything
>you can to get them to test for clopyralid residue, either through lab
>tests, with low detection limits, or through bioassays (growth trials) of
>susceptible plants (peas, beans, tomatoes and sunflowers).  You would thing
>compost facility operators would really be on top of this issue, but I
>talked to one yesterday who told me he is doing growth trials on rye grass,
>which would of course not respond in the least to the clopyralid residue.
>   I have heard that it can take as long as 4 weeks for susceptible crop
>plants to show the affects of the residue.
>Please keep me in the loop, whatever you decide to do.  I would like to
>start a movement towards local government action plans up here in northern
>California, and it always helps to have a model.
