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 cancer, an exemption from the above requirements 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 poses no significant risk or that a discharge which otherwise complies with all applicable requirements would not cause any significant amount of the discharged or released chemical to enter any source of drinking water (Health and Safety Code Sections 25249.9 and 25249.10). A determination that a level of exposure poses no significant risk may be made utilizing regulations that have previously been adopted by the Office of Environmental Health Hazard Assessment (22 CCR Sections 12701-12721). Section 12701 describes alternative methods for making such a determination. Section 12705 sets forth the process by which the Office of Environmental Health Hazard Assessment may identify specific regulatory levels for determining "no significant risk" for purposes of Proposition 65.

For chemicals known to the State to cause reproductive toxicity, an exemption from the warning requirement and discharge prohibition discussed above is provided by the Act when a person in the course of doing business can demonstrate that an exposure for which he or she is responsible produces no observable effect, assuming exposure at 1,000 times the level in question, or a discharge which otherwise complies with all applicable requirements would not cause any significant amount of the discharged or released chemical to enter any source of drinking water (Health and Safety Code Sections 25249.9 and 25249.10). 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.

This amendment to Section 12705(b) would adopt the following "no significant risk" levels for chemicals listed as known to cause cancer:

The amendment to Section 12705(d) would adopt the following "no significant risk" levels for chemicals listed as known to cause cancer:

The amendment to Section 12805 would adopt the following regulatory levels for chemicals known to the state to cause reproductive toxicity:

The risk assessments which were used by the Office of Environmental Health Hazard Assessment to determine the stated levels are as follows:

AUTHORITY

Health and Safety Code Section 25249.12.

REFERENCE

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 does not affect small business as the term is defined by Government Code Section 11342.610 since Proposition 65 does not apply to businesses with fewer than ten employees.

CONSIDERATION OF ALTERNATIVES

In accordance with Government Code Section 11346.5(a)(13), OEHHA has determined 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.
