           ASSEMBLY COMMITTEE ON ENVIRONMENTAL SAFETY AND TOXIC MATERIALS
                                  Pedro Nava, Chair
                    HR 23 (Monning) - As Amended:  March 10, 2010
           
          SUBJECT  :   Inert ingredients in pesticides.

           SUMMARY  :   This resolution requests that the United States  
          Environmental Protection Agency (USEPA) acts to protect public  
          health and the environment by requiring the disclosure of inert  
          ingredients in pesticide products.  Specifically,  this  
          resolution  : 



          1)Makes a series of legislative findings about pesticide use and  
            the potential human health and environmental risks posed by  
            inert ingredients in pesticides. 



          2)Memorializes that the Assembly of the State of California  
            (Assembly) urges the Governor to request USEPA to act  
            expeditiously to protect public health and the environment by  
            requiring the disclosure of the identity of inert ingredients  
            on pesticide product labels.



          3)Memorializes that the Assembly urges the Governor to request  
            USEPA to require the identification of hazardous inert  
            ingredients as quickly as possible and begin the process of  
            requiring disclosure of all inert ingredients, absent a  
            finding that disclosure of a particular ingredient will cause  
            competitive harm.



          4)Memorializes that the Assembly urges the Governor's continued  
            support of the public's right to know every ingredient in  
            pesticide products.

                                                                  HR 23
                                                                  Page 2

          1)Under the Federal Insecticide, Fungicide, and Rodenticide Act  
            (FIFRA):

             a)   Defines an "active ingredient" as one that prevents,  
               destroys, repels or mitigates a pest, or is a plant  
               regulator, defoliant, desiccant or nitrogen stabilizer.   
               Requires the active ingredient to be identified by name on  
               the label together with its percentage by weight.

             b)   Defines an "inert ingredient" as any substance, or group  
               of structurally similar substances if designated by the  
               USEPA, other than an active ingredient, which is  
               intentionally included in a pesticide product.

             c)   Requires the total percentage of inert ingredients to be  
               on the pesticide product label.

           FISCAL EFFECT  :   Unknown.

           COMMENTS  :   

           Purpose of the resolution:   According to the author's office,  
          "At the present time, neither California nor federal law  
          requires that pesticide ingredients be fully identified on the  
          labels of pesticide products.  In December 2009, the U.S.  
          Environmental Protection Agency proposed to increase the amount  
          of disclosure required.  The purpose of this resolution is to  
          support this federal initiative."



           Potential health and environmental risks of inert ingredients  :   
          According to a 2006 article in Environmental Health  
          Perspectives, "despite their name, inert ingredients may be  
          biologically or chemically active and are labeled inert only  
          because of their function in the formulated product. Most of the  
          tests required to register a pesticide are performed with the  
          active ingredient alone, not the full pesticide formulation.   
          Inert ingredients are generally not identified on product labels  
          and are often claimed to be confidential business information.   
          Inert ingredients can increase the ability of pesticide  
          formulations to affect significant toxicologic end points,  
          including developmental neurotoxicity, genotoxicity, and  
          disruption of hormone function.  They can also increase exposure  
          by increasing dermal absorption, decreasing the efficacy of

                                                                  Page 3

          protective clothing, and increasing environmental mobility and  
          persistence.  Inert ingredients can increase the phytotoxicity  
          of pesticide formulations as well as the toxicity to fish,  
          amphibians, and microorganisms."

           Federal action on inert ingredients  :  According to the USEPA's  
          website, "EPA believes disclosure of inert ingredients on  
          product labels is important to consumers who want to be aware of  
          all potentially toxic chemicals, both active and inert  
          ingredients, in pesticide products."  On December 22, 2009,  
          USEPA announced that it was seeking comment on options for  
          increasing public disclosure of all inert ingredients in  
          pesticides registered under FIFRA.  The public comment period on  
          this rule making process closed on April 23, 2010.  

           Related legislation  :

          SR 35 (Leno).  Urges the Governor to request USEPA to require  
          identification of inert ingredients in pesticide products, and  
          urges the Governor's continued support of the public's right to  
          know ingredient in pesticide products.  Adopted by the Senate on  
          April 22, 2010.
