STAFF REPORT
REQUEST: CONSIDERATION OF SUPPORTING LEGISLATION BANNING OR
LIMITING THE USE OF HERBICIDE CLOPYRALID IN THE STATE
OF CALIFORNIA.
DATE: MAY 9, 2002
CONTENTS: MEMORANDUM FROM FRANKIE RIDDLE, MANAGMENT
ANALYST
Recommendation:
By Minute Motion, concur with the action taken by the Legislative Review Committee at its
meeting of April 16, 2002, and direct staff to prepare a letter to the California Integrated
Waste Management Board regarding the City of Palm Desert's support of legislation
banning or limiting the use of the herbicide Clopyralid in the State of California.
Executive Summary:
The California Integrated Waste Management Board is seeking input from local
jurisdictions regarding the use of the herbicide Clopyralid and its impact on composting in
California.
Background:
Staff was requested to research the current use of the herbicide Clopyralid for local
agricultural uses. At the present time, neither the City of Palm Desert or Desert Willow use
this as an approved chemical product with regard to landscaping its properties. Because
of the potential for toxicity to plants, animals, and humans via its presence in composting
and everyday soil,the California Integrated Waste Management Board is requesting input
from local entities. After staff conducted research, it is staff's recommendation that the City
of Palm Desert oppose its use.

To: ROBERT P. KOHN, CONTRACTS ADMINISTRATOR
From: FRANKIE RIDDLE, MANAGEMENT ANALYST
Date: MARCH 3, 2002
Subject: RESEARCH ON CLOPYRALID USE, SUGGESTED
RECOMMENDATIONS, AND ITS IMPACT THE COMPOST
INDUSTRY
Per your request, research was conducted on the use of Clopyralid, its effects, and legislation
on this issue on a local level, in California, and in Washington. Staff contacted several sources
to determine the use of this herbicide and effects, if any.
After some research, it was apparent that several products contained the herbicide Clopyralid.
Some of the known products to contain Clopyralid (which is a herbicide used to control
broadleaf weeds in turf) are Confront, Stinger, Lontrel, Reclaim, and Translini Anatek. It was
noted that Clopyralid is a herbicide used to kill broadleaf weeds and was originally used for
agriculture. This was not a real problem until green waste recycling (50% diversion and
composting) came into play.
Contact was made with Palm Desert Public Works Department regarding use of the herbicide
within parks and medians, Desert Willow Resort & Golf Course use, California Bio-Mass, Inc.
(the major compost facility that receives green waste from Waste Management), Shirley Wild-
Wagner of California Integrated Waste Management Board, and Dave Galvin, King County
Washington. Outlined below is information obtained from each of the contacts made and the
results:
I. City of Palm Desert and Desert Willow:
Staff contacted Ernie Owens, Public Works Parks regarding use of weed killers and other
products used on City parks and medians. Ernie provided a list of chemicals (attachment
1) used by the Public Works Department on City parks and medians, etc. Spencer Knight
reviewed the list to determine if Clopyralid was a component of the listed products. To his
knowledge none of the products listed contained the noted herbicide.
Desert Willow Maintenance Supervisor Rudy was contacted to determine if Clopyralid was
used as weed control on Desert Willow courses. Rudy indicated that the primary products
used in the maintenance of landscaping and courses are Premo, Roundup, and Reward.

Impact on the Compost Industry
II. California Bio-Mass:
Staff contacted John Beerman of California Bio-Mass regarding local effects, composting
process, and testing of Clopyralid at its facility. California Bio-Mass is one of the primary
company's that receives green waste from Waste Management of the Desert.
Since becoming aware of this issue, Mr. Beerman has done several things to determine
the presence and damage of Clopyralid in the compost. Some of the items reviewed by
California Bio-Mass are: (1) Surveying of some of the local suppliers of landscape and
turf products and according to the ones contacted most of their products are sold to
customers out of the Coachella Valley area; (2) monthly testing; and (3) on-site plantingof
.
green beans and peas within compost to determine growth and presence of the herbicide.
He noted that the compost process cycle undergone at California Bio-Mass is a two stage
composting processing cycle. By the time the material arrives on-site it is a 12-month
cycle; the first stage is 6 to10 months, the second stage is 60 to 90 days, and the third
stage is a curing pile for cool down. As part of the process, monthly testing is undertaken
to determine the presence of pathogens (i.e., fecal coliform salmonella, and heavy metals)
(Attachment 2). California Bio-Mass is testing for the herbicide in the parts per billion.
They as well as other compost facilities in the state are currently testing and monitoring for
the presence of Clopyralid.
California Bio-Mass distributes all of its compost back into the market except for
cogeneration (Colmac) use. The distribution is approximately somewhere around 65% -
70% agriculture, 15% - 20% landscape and golf courses, and 10% nurseries, except for
cogeneration (Colmac) use that is approximately 10% - 15%. None of the compost is
utilized as Alternative Daily Cover (ADC).
III. California Integrated Waste Management Board:
Staff spoke with Shirley Wild-Wagner at the CIWMB regarding Clopyralid and what was
occurring at Board level. According to Ms. Wild-Wager the CIMWB is aware of the impact
of this herbicide and will be addressing this issue at the March 6, 2002, CIWMB Board
Meeting. The Agenda Item, under"Background" discusses the history and to date actions
taken by CIWMB to address this issue in California and briefly the impact on Washington.
(See Attachment 3, Board Agenda Item 2)
Outlined below are a few of the items addressed in the agenda item:
Responsibility of CIWMB: CIWMB is responsible for regulating the composting facilities
that could be affected by Clopyralid-containing feedstock, but it has no regulatory authority
regarding pesticides; therefore, CIWMB has been working with the Department of
Pesticide Regulation (DPR) to review and assess the potential impact and solution to this
issue. DPR has notified registrants of products containing Clopyralid about potential
problems of compost contamination in California and of the department's intent to address
the problems.

Research on Clopyralid Use, Suggested Recommendations, and
Impact on the Compost Industry
Background: According to the agenda report, which refers to the Seattle Times, the
State of Washington has experienced some misfortunes due to use of Clopyralid that was
found in the compost. It was reported that in 2001 damages in lost sales by one facility
was reported at $155,000 and claims of almost $13,000 were brought against the City of
Spoken, and the State paid over $250,000. The report does not indicate that the State of
California has experienced any damages due to this herbicide; however, reports verify the
its presence at two composting facilities, and that stakeholders and cities and counties are
concerned that this could put a damper on consumer confidence, which would affect the
ability to sell compost products and in-turn effect diversion efforts.
The report does not provide information on money damages, if any. The report provides
more detailed information of the actions taken by CIWMD.
Some of the options being recommended by Stakeholders are: (1) The U.S.
Composting Council has called on Dow to work with U.S. EPA to clarify the liabilities of
applicators and harvesters regarding proper disposal or recycling of grass clippings or
other Clopyralid-treated residues that might be applied to non-targeted plants, and to
investigate approved applications for potential problems in compost and other
applications. Also, that Dow should compensate composters and organic growers for
costs associated with the use of this herbicide; (2) The GrassRoots Recycling Network
has called for a ban; (3) Los Angeles County Board of Supervisors directed the Director of
Health Services, the Agricultural Commission, and the County Sanitation Districts to
investigate and report back within 30 days with recommended actions to ensure that this
herbicide is kept out of county compost sites; and (4) Dow is considering a variety of label
updates to clarify instructions and use restrictions.
Potential Options for Board Discussion: CIWMB staff's recommendations to the Board
are: (1) Prepare Board publications on Clopyralid and composting; (2) Publicizing
information, perhaps in coordination with DPR, on alternatives to chemicals; (3) Educating
targeted end-user associations about labeling instructions, proper products use, and the
need to avoid contamination of potential feedstocks; (4) Working with DPR,
manufacturers, and composting and environmental organizations to develop
recommended revisions to Clopyralid product labels and forward the recommendations to
the U.S. EPA; (5) Working with DPR and composting organizations to establish a testing
program or other investigatory protocol in California that would provide the technical
information DPR needs to consider regulatory actions; and (6) Supporting legislation that
attempts to mitigate or eliminate the potential effects of Clopyralid on the composting
industry in California.

IV. Discussion with Dave Galvin, KingCounty, Washington State:
Discussion with Mr. Galvin revealed that the original use of Clopyralid was in the
agriculture field not the landscaping area. However, he noted that the herbicide did show
up in the Washington State University's research when it was used with hay. This was
due to contaminated hay and straw used for livestock bedding; the bedding and manure
were subsequently recycled at compost facilities and then went back into the market. The
real problem arose once this source was utilized for compost and sold back into the
market for various uses (i.e., nurseries).
It was noted that the original intent and use of the herbicide (i.e., agriculture) allowed for
decomposition; however, now grass and hay clippings are recycled and transferred to
compost facilities for recycling. It is speculated that the high temperatures generated
(approximately 130 degrees Fahrenheit) does not allow the herbicide to breakdown. This
has not been confirmed. (See Attachment 5)
According to Mr. Galvin the County has worked with the Department of Agriculture to ban
the use of Clopyralid in the State of Washington in the lawn and turf fields. The only
exemption would be golf courses, which would be required to retain grass and tree
leavings on-site. There will be an Emergency Rule (attachment 4) banning the use of this
herbicide put into effect immediately. (Per email from Mr. Dave Galvin, the ban on lawn
application of this herbicide went into effect on March 1, 2002.)
V. Conclusion:
If California does not take some type of action, it may start having similar experiences to
the State of Washington. No action, would eventually have a negative affect on the
composting industry in California and locally. Continued use of Clopyralid could result in
product damages that would result in loss of sales, which then could have the trickle effect
and in the case of the State of Washington result in claims filed against the State and
cities. Also, there is the potential negative affect on the State's, cities, and counties
diversion plans and programs, and meeting the 50% diversion mandate.
