INFORMATIVE DIGEST/POLICY STATEMENT OVERVIEW
The Safe Drinking Water and Toxic Enforcement Act of 1986, commonly known as Proposition 65 (hereinafter referred to as "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 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 such persons from knowingly discharging a listed chemical into water or onto or into land where such chemicals pass 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 he or she is responsible produces no observable reproductive effect, assuming exposure at 1,000 times the level in question (Health and Safety Code Section 25249.10). 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). The term "significant amount" is defined in a manner that equates to the level that triggers the warning requirement. Thus, these exemptions apply when an exposure or discharge does not exceed the NOEL divided by 1,000. One method by which a person in the course of doing business may determine whether an exposure or a discharge is exempt from the Act is by application of the specific regulatory level for the chemical in Section 12805. The levels in Section 12805 represent the maximum dose level at which the chemical has no observable reproductive effect, given an exposure at one thousand (1,000) times the level in question.
The amendment to Section 12805 would adopt the following regulatory levels for chemicals known to the state to cause reproductive toxicity:
|Chemical||MADL, in units micrograms per day||Reference|
|2,4-D butyric acid (2,4-DB, 2,4-dichlorophenoxybutyric acid)||910||OEHHA (2003a)|
|m-Dinitrobenzene||38 (oral)||OEHHA (2003b)|
|Hydramethylnon||120 (oral)||OEHHA (2003c)|
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.
