INFORMATIVE DIGEST/POLICY STATEMENT OVERVIEW
The Safe Drinking Water and Toxic Enforcement Act of 1986, codified at Health and Safety Code section 25249.5 et seq. and commonly known as Proposition 65 (hereinafter Proposition 65 or the Act), prohibits a person in the course of doing business from knowingly and intentionally exposing any individual to a chemical that has been listed as known to the State to cause cancer or reproductive toxicity, without first giving clear and reasonable warning to such individual (Health and Safety Code section 25249.6). The Act also prohibits a business from knowingly discharging a listed chemical into water or onto or into land where such chemical passes or probably will pass into any source of drinking water (Health and Safety Code section 25249.5).
For chemicals known to the state to cause reproductive toxicity, an exemption from the warning requirement is provided by the Act when a person in the course of doing business is able to demonstrate that an exposure for which the person is responsible produces no observable reproductive effect, assuming exposure at 1,000 times the level in question (Health and Safety Code sections 25249.9, 25249.10 and 25249.11). The maximum dose level at which a chemical has no observable reproductive effect is referred to as the no observable effect level (NOEL). The Act also provides an exemption from the prohibition against discharging a listed chemical into sources of drinking water if the amount discharged does not constitute a “significant amount,” as defined, and the discharge is in conformity with all other laws and regulatory requirements (Health and Safety Code sections 25249.9 and 25249.11). Thus, these exemptions apply when the exposure or discharge in question is at a level that does not exceed the NOEL divided by 1,000.
Regulations previously adopted by the Office of Environmental Health Hazard Assessment (OEHHA) provide guidance for determining whether an exposure to, or a discharge of, a chemical known to cause reproductive toxicity meets the statutory exemption (Title 22, California Code of Regulations, sections 12801-12821). These regulations provide three ways by which a person in the course of doing business may make such a determination: (1) by conducting a risk assessment in accordance with the principles described in Section 12803 to derive a NOEL, and dividing the NOEL by 1,000; or (2) by application of the specific regulatory level adopted for the chemical in Section 12805; or (3) in the absence of such a level, by using a risk assessment conducted by a state or federal agency, provided that such assessment substantially complies with Section 12803(a). The specific regulatory levels in Section 12805 represent one one-thousandth of the NOEL.
This proposed regulation sets forth maximum allowable dose levels (MADLs) for adoption into Section 12805 that were derived using scientific methods outlined in Section 12803.
Details on the basis for the proposed levels are provided in the references cited below, which are also included in the rulemaking record. The references are risk assessment documents prepared by OEHHA describing and summarizing the derivation of the regulatory levels listed below.
The proposed regulation would adopt the following regulatory levels for three chemicals known to cause reproductive toxicity into Section 12805:
Ethylene glycol monoethyl ether (EGEE)
MADL, in units
micrograms per day: 750 (oral exposure)
MADL, in units
micrograms per day: 960 (inhalation exposure)
Ethylene glycol monoethyl ether acetate (EGEEA)
MADL, in units micrograms per day: 1,100 (oral exposure)
MADL, in units
micrograms per day: 1,400 (inhalation exposure)
Chemical: Potassium dimethyldithiocarbamate
MADL, in units micrograms per day: 720
The risk assessments which were used by the Office of Environmental Health Hazard Assessment to determine the stated levels are as follows:
Office of Environmental Health Hazard Assessment (OEHHA, 2007a). Proposition 65 Maximum Allowable Dose Level (MADL) for Reproductive Toxicity for Ethylene Glycol Monoethyl Ether (EGEE) and Ethylene Glycol Monoethyl Ether Acetate (EGEEA). OEHHA Reproductive and Cancer Hazard Assessment Section, California Environmental Protection Agency, Sacramento, February 2007.
Office of Environmental Health Hazard Assessment (OEHHA, 2007b). Proposition 65 Maximum Allowable Dose Level (MADL) for Reproductive Toxicity for Potassium Dimethyldithiocarbamate. OEHHA Reproductive and Cancer Hazard Assessment Section, California Environmental Protection Agency, Sacramento, February 2007.
Health and Safety Code Section 25249.12.
Health and Safety Code Sections 25249.5, 25249.6, 25249.9, 25249.10 and 25249.11.
IMPACT ON LOCAL AGENCIES OR SCHOOL DISTRICTS
OEHHA has determined the proposed regulatory action would not pose a mandate on local agencies or school districts nor does it require reimbursement by the State pursuant to Part 7 (commencing with Section 17500) of Division 4 of the Government Code. The Office of Environmental Health Hazard Assessment has also determined that no nondiscretionary costs or savings to local agencies or school districts will result from the proposed regulatory action.
COSTS OR SAVINGS TO STATE AGENCIES
OEHHA has determined that no savings or increased costs to any State agency will result from the proposed regulatory action.
EFFECT ON FEDERAL FUNDING TO THE STATE
OEHHA has determined that no costs or savings in federal funding to the State will result from the proposed regulatory action.
EFFECT ON HOUSING COSTS
OEHHA has determined that the proposed regulatory action will have no effect on housing costs.
SIGNIFICANT STATEWIDE ADVERSE ECONOMIC IMPACT DIRECTLY AFFECTING BUSINESS, INCLUDING ABILITY TO COMPETE
OEHHA has made an initial determination that the adoption of the regulation will not have a significant statewide adverse economic impact directly affecting businesses, including the ability of California businesses to compete with businesses in other states.
IMPACT ON THE CREATION, ELIMINATION, OR EXPANSION OF JOBS/BUSINESSES
OEHHA has determined that the proposed regulatory action will not have any impact on the creation or elimination of jobs, the creation of new businesses or the elimination of existing businesses, or the expansion of businesses currently doing business within the State of California.
COST IMPACTS ON REPRESENTATIVE PRIVATE PERSONS OR BUSINESSES
OEHHA is not aware of any cost impacts that a representative private person or business would necessarily incur in reasonable compliance with the proposed action.
EFFECT ON SMALL BUSINESSES
OEHHA has determined that the proposed regulation will not impose any requirements on small business. Rather, the proposed regulation will assist small businesses subject to the Act in determining whether or not an exposure for which they are responsible is subject to the warning requirement or discharge prohibition.
CONSIDERATION OF ALTERNATIVES
In accordance with Government Code Section 11346.5(a)(13), OEHHA must determine that no reasonable alternative considered by OEHHA, or that has otherwise been identified and brought to the attention of OEHHA would be more effective in carrying out the purpose for which the action is proposed or would be as effective and less burdensome to affected private persons than the proposed action.
AVAILABILITY OF STATEMENT OF REASONS AND TEXT OF PROPOSED REGULATIONS
OEHHA has prepared and has available for public review an Initial Statement of Reasons for the regulation, all the critical information upon which the regulation is based, and the text of the regulation.

AVAILABILITY OF CHANGED OR MODIFIED TEXT: The full text of any regulation which is changed or modified from the express terms of the proposed action will be made available at least 15 days prior to the date on which OEHHA adopts the resulting regulation. Notice of the comment period on changed regulations and the full text will be mailed to individuals who testified or submitted written comments at the public hearing, whose comments were received by OEHHA during the public comment period, and who request notification from OEHHA of availability of such changes. Copies of the notice and the changed regulation will also be available at the OEHHA’s Web site at www.oehha.ca.gov.
