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. 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 OEHHA (Sections 12701-12721). Section 12701 describes alternative methods for making such a determination. Section 12705 sets forth the process by which OEHHA may identify specific regulatory levels for determining “no significant risk” for purposes of Proposition 65.
Details on the basis for the proposed level are provided in the references cited below, which is incorporated in the rulemaking record. The references are risk assessment documents prepared by OEHHA describing and summarizing the derivation of the regulatory levels listed below.
This amendment to Section 12705(b) would adopt the following “no significant risk” levels for one chemical listed as known to cause cancer:
|
Chemical |
NSRL, in units |
Reference |
|---|---|---|
| Ethylbenzene (inhalation) |
54
|
OEHHA (2007, 2008)
|
| Ethylbenzene (oral) |
41
|
OEHHA (2007, 2008)

The risk assessment used by the OEHHA to determine the stated levels is as follows:
Office of Environmental Health Hazard Assessment (OEHHA, 2007). Notice of Adoption of Unit Risk Value for Ethylbenzene. Attachment: Long-Term Health Effects of Exposure to Ethylbenzene. Air Toxicology and Epidemiology Branch, OEHHA.
Office of Environmental Health Hazard Assessment (OEHHA, 2008). No Significant Risk Level (NSRL) for the Proposition 65 Carcinogen Ethylbenzene. OEHHA, Reproductive and Cancer Hazard Assessment Branch, California Environmental Protection Agency, Oakland, February 2008.
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. OEHHA 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
The 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 businesses. 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.
