Cal. Code Regs. tit. 27, § 27000 – Chemicals Required by State or Federal Law to Have Been Tested for Potential to Cause Cancer or Reproductive Toxicity, but Which Have Not Been Adequately Tested As Required.

(a) The Safe Drinking Water and Toxic Enforcement Act of 1986 requires the Governor to publish a list of chemicals formally required by state or federal agencies to have testing for carcinogenicity or reproductive toxicity, but that the state's qualified experts have not found to have been adequately tested as required [Health and Safety Code Section 25249.8(c)].
(b) Chemicals required to be tested by the California Department of Pesticide Regulation.
1. (1) The Birth Defect Prevention Act of 1984 (SB 950) mandates that the California Department of Pesticide Regulation (CDPR) review chronic toxicology studies supporting the registration of pesticidal active ingredients. Missing or unacceptable studies are identified as data gaps.
2. (2) The studies are conducted to fulfill generic data requirements of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), which is administered by the United States Environmental Protection Agency (U.S. EPA).
3. (3) The studies are reviewed by CDPR according to guidelines and standards promulgated under FIFRA. Older studies may not meet current guidelines.
4. (4) The existence of a data gap for a compound does not indicate a total lack of information on the carcinogenicity or reproductive toxicity of the compound. In some cases, information exists in the open scientific literature, but SB 950 requires specific additional information.
5. (5) A data gap does not necessarily indicate that an oncogenic or reproductive hazard exists. For the purposes of this list, a data gap is still considered to be present until the study is reviewed and found to be acceptable.
6. (6) Following is a listing of SB 950 data gaps for oncogenicity, reproduction, and teratology studies for pesticidal active ingredients. This list changes as data gaps are filled by additional data or replacement studies.
7. (7) For purposes of this section, “onc mouse” means oncogenicity in mice, “onc rat” means oncogenicity in rats, “repro” means reproduction, “tera rat” means teratogenicity in rats, “tera rabbit” means teratogenicity in rabbits.

  * Claims are pending review that data should not be required.
  ** No product containing this active ingredient is registered with CDPR.
(c) Chemicals required to be tested by the U.S. EPA, Office of Pollution Prevention and Toxics.
1. (1) Under 15 U.S.C.A. § 2603(a) of the Toxic Substances Control Act, testing of a chemical is required when that chemical may present an unreasonable risk, or is produced in substantial quantities and enters the environment in substantial quantities, or may have significant or substantial human exposure.
2. (2) For purposes of this section, “tera” means teratogenicity, “rtox” means reproductive toxicity, “onc” means oncogenicity.
  Chemical
  Testing Needed
  Hydrocarbons, C>4
  rtox
  Trifluoro(trifluoromethyl)oxirane (also known as HFPO)
  onc, rtox, tera
(d) Chemicals required to be tested by the U.S. EPA, Office of Pesticide Programs.
1. (1) The U.S. EPA is responsible for the regulation of pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). FIFRA requires U.S. EPA to register pesticides based on data adequate to demonstrate that they will not result in unreasonable adverse effects to people or the environment when used in accordance with their U.S. EPA-approved labels.
2. (2) The chemicals listed below are those for which data are unavailable or inadequate to characterize oncogenicity, teratogenicity, or reproductive effects potential. For purposes of this section, “onc” means oncogenicity, “tera” means teratogenicity, and “repro” means reproductive toxicity.
