INFORMATIVE DIGEST/POLICY STATEMENT OVERVIEW

Proposition 65 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 carcinogens, an exemption from the warning requirement is provided by the Act when the exposure for which the person is responsible can be demonstrated to produce 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 25701-25721).  Section 25701 describes alternative methods for making such a determination.  Section 25705 sets forth the process for determining “no significant risk” levels for purposes of Proposition 65 and establishes those levels for certain listed chemicals. 

Details on the bases for the proposed levels are provided in the initial statement of reasons for this regulatory amendment, which is available on request from Monet Vela and is posted on the OEHHA web site at www.oehha.ca.gov. 

This proposed amendment to section 25705 would update the existing No Significant Risk Levels (NSRLs) for Trichloroethylene by amending Section 25705(b) as follows: 


Chemical

NSRL, in units micrograms per day

Trichloroethylene

14 (oral)
50 (inhalation)

The proposed updated NSRLs for trichloroethylene are based upon a risk assessment performed by the U.S. Environmental Protection Agency (U.S. EPA) that OEHHA has reviewed and determined to be consistent with Section 25703.  The oral and inhalation cancer potency values developed in the U.S. EPA risk assessment provide the basis for calculating the proposed oral and inhalation NSRLs, respectively.  This is discussed in more detail in the initial statement of reasons for this proposed regulatory amendment.

This notice and the initial statement of reasons are being provided to the OEHHA Science Advisory Board’s Carcinogen Identification Committee for review and comment.

Specific Benefits Anticipated by the Regulation:     See “Benefits of the Proposed Regulation” under “RESULTS OF THE ECONOMIC IMPACT ANALYSIS” below.

OEHHA has determined that the proposed regulation is neither inconsistent nor incompatible with existing state regulations because it provides compliance assistance to businesses subject to the Act, but does not impose any mandatory requirements on those businesses, state or local agencies and does not address compliance with any other law or regulation.

RESULTS OF ECONOMIC IMPACT ANALYSIS (Gov. Code section 11346.3(b))

Impact on the Creation, Elimination, or Expansion of Jobs/Businesses in California

This regulatory proposal will not affect the creation or elimination of jobs within the State of California.  Proposition 65 requires businesses with ten or more employees to provide warnings when they expose people to chemicals that are known to cause cancer or developmental or reproductive harm.  The law also prohibits the discharge of listed chemicals into sources of drinking water.  Trichloroethylene is listed under Proposition 65, therefore businesses and individuals who manufacture, distribute, or sell products with trichloroethylene in the state must provide a warning if their product or activity exposes the public or employees to this chemical.

Because the proposed regulatory levels provide compliance assistance to businesses subject to the Act, but do not impose any mandatory requirements on those 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.

Benefits of the Proposed Regulation:  Some businesses may not be able to afford the expense of establishing an NSRL or MADL and therefore may be exposed to litigation for a failure to warn or for a prohibited discharge of the listed chemical.  Adopting this regulation will save these businesses those expenses and may reduce litigation costs.  By providing a safe harbor level, this regulatory proposal does not require, but may encourage businesses to lower the amount of the listed chemical in their product to a level that does not cause a significant exposure.  This in turn may reduce state’s residents, worker and environmental exposures to chemicals that cause cancer, developmental or reproductive harm.

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

Because Proposition 65 expressly does not apply to local agencies or school districts, OEHHA has determined the proposed regulatory action would not impose 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
Because Proposition 65 expressly does not apply to any State agency, 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

Because Proposition 65 expressly does not apply to any federal agency, 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 because it provides compliance assistance to businesses subject to the Act, but does not impose any mandatory requirements on those businesses. 

SIGNIFICANT STATEWIDE ADVERSE ECONOMIC IMPACT DIRECTLY AFFECTING BUSINESS, INCLUDING ABILITY TO COMPETE

Because the proposed regulatory levels provide compliance assistance to businesses subject to the Act, but do not impose any mandatory requirements on those businesses, 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. 

COST IMPACTS ON REPRESENTATIVE PRIVATE PERSONS OR BUSINESSES

Since the proposed regulatory levels provide compliance assistance to businesses subject to the Act, but do not impose any mandatory requirements on those businesses, the Office of Environmental Health Hazard Assessment 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 mandatory requirements on small business.  Rather, the proposed regulation will provide compliance assistance for small businesses subject to the Act because it will help them determine whether or not an exposure for which they are responsible is subject to the warning requirement or discharge prohibition of the Act. 

CONSIDERATION OF ALTERNATIVES

Government Code Section 11346.5(a)(13) requires that 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, or would be more cost-effective to affected private persons and equally effective in implementing the statutory policy or other provision of law.

AVAILABILITY OF CHANGED OR MODIFIED TEXT

The full text of any regulation which is changed or modified from the express terms of this 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, if held, or whose comments were received by OEHHA during the public comment period, and anyone who requests notification from OEHHA of the availability of such changes.  Copies of the notice and the changed regulation will also be available on the OEHHA Web site at www.oehha.ca.gov.
