NRDC Files Petition for Review To Ban Flea Collars and Pet Products Containing Pesticides
On January 5, 2015, the Natural Resources Defense Council (NRDC) filed a petition for review in the U.S. Court of Appeals for the Ninth Circuit challenging the November 6, 2014, decision of the U.S. Environmental Protection Agency (EPA) to allow the continued use of tetrachlovinphos (TCVP) in flea control products used on pets. NRDC’s 2009 petition sought to cancel all pet uses of TCVP based on alleged potential health risks to children.
In February 2014, NRDC filed a petition for a writ of mandamus in the United States Court of Appeals for the District of Columbia Circuit seeking the court to compel EPA to respond to NRDC’s petitions to cancel all manufacturer registrations and uses of propoxur and TCVP, which are used in pet flea treatment products. Sergeant’s Pet Care Products, Inc., Wellmark International, and Hartz were among flea collar brands at issue.
In March 2014, EPA announced an agreement with Sergeant’s Pet Care Products, Inc. and Wellmark International, whereby the companies voluntarily cancelled the use of propoxur in flea collars. Related uses of other chemicals, including TCVP in pet collars, were not addressed in that agreement, and EPA denied, in November 2014, NRDC’s 2009 petition seeking to cancel all pet uses of TCVP.
NRDC first petitioned EPA to cancel propoxur uses in pet collars in 2007. NRDC filed a petition in April 2009 to cancel all pet uses of TCVP based on its Poison on Pets II report, which asserted that unsafe levels of pesticide residues are present on dogs and cats after a flea collar is used.
EPA conducted a risk assessment of multiple pet use products (e.g., shampoos, dips, powders, and flea collars) containing TCVP in 2006 during the reregistration process. The majority of the uses were assessed using registrant-submitted chemical-specific data. Potential post-application assessments for the majority of the uses included assessing dermal contact with the treated animal (e.g., a child hugging a dog) and hand-to-mouth contact by a toddler following contact with treated animals (e.g., touching the dog and then putting their hand in their mouth). These were considered to be worst-case assessments based on the amount of dermal and hand-to-mouth contact used by EPA. Potential post-application exposure to adults and children were not assessed for flea collars. In the case of flea collars, EPA concluded: “Post application exposure to residues from pet collars is considered to be insignificant when compared with exposure to other products. Because other, higher exposure uses were not of concern, an assessment for collars was not conducted.”
This last sentence is especially important, as EPA is likely to reiterate this conclusion, whether curtly or in detail, as its direct response to the petition. As this is a fairly predictable Agency response, NRDC appears to want this petition to signal its continuing concerns about organophosphate use generally, and be able to raise concerns about “children’s risks” in particular.
