California Extends Public Comment Period for Proposed Green Chemistry Regulations

Green Products Update

Date: September 04, 2012


California's Department of Toxic Substances Control (DTSC) recently released its long-awaited formal draft of its Safer Consumer Products regulations. Due to numerous requests, the DTSC has extended the 45-day public comment period for the regulations from September 11, 2012 to October 11, 2012. The public hearing will proceed as scheduled on September 10, 2012.

The state's regulations will require product manufacturers to consider the toxicity of components and raw materials when designing their products. They follow a series of informal proposals made by California regulators pursuant to California's 2008 "Green Chemistry Initiative" law; those proposals were met with heavy criticism by environmental and public health groups, scientists, and industry.

California's latest version narrows the scope of the regulations to include fewer initial Chemicals of Concern (COCs), but also provides fewer exceptions to the regulations.


In 2008, California passed legislation requiring DTSC to have its regulations in place by January 1, 2011. Previously, an increasing number of chemical-specific bills had been introduced to ban particular chemicals or restrict their use in certain products. The Green Chemistry Initiative regulations attempt to create a systematic regulatory process that potentially addresses all chemicals.

The regulations also attempt to force manufacturers to consider, at the design stage, the toxicity of the components and raw materials used in their products. The hope is that imposing this burden will lead to the manufacture of consumer products that contain fewer toxic substances. Under the law, the regulations must provide a science-based approach for:

  • Developing a list of chemicals that pose the greatest risks,
  • Identifying products that contain the chemicals, and
  • Analyzing safer alternatives.
A Four-Step Process

The formal proposed regulations refine the previously proposed continuous, science-based, iterative four-step process for identifying safer consumer product alternatives as follows:

  1. Chemicals of Concern. The regulations establish an immediate list of approximately 1,200 COCs (down from 3,000) that "exhibit a hazard trait or an environmental or toxicological endpoint," or are identified by other authoritative organizations. The regulations also specify a process for DTSC to identify additional chemicals as COCs.
  2. Product Prioritization. The regulations require DTSC to develop a list of "Priority Products" for which an Alternatives Analysis (AA) must be conducted. DTSC specifically noted that the initial Priority Products list will include no more than five products. If a Priority Product meets the AA threshold for the particular COCs in a product, the manufacturer may be exempt from having to conduct an AA. DTSC must specify the AA threshold for each COC.
  3. Responsibility for Compliance. The regulations impose the responsibility for compliance on manufacturers, product retailers, and importers. Responsible entities must notify DTSC when their product is listed as a Priority Product or qualifies for an AA threshold exemption, conduct an AA for any Priority Products, and submit both a preliminary and a final AA report to DTSC.
  4. Regulatory Responses. The regulations require DTSC to identify and impose regulatory responses to protect public health and the environment, and to maximize the use of alternatives of least concern whenever technically and economically feasible. DTSC may place use restrictions on COCs and Priority Products, or prohibit altogether the sale of Priority Products containing COCs if alternatives exist. DTSC will maintain a "Response Status" list on its website, where it will post, among other things, whether a responsible entity failed to make the information requested available to DTSC within the specified time period, and whether it satisfactorily demonstrated it does not have, and is unable to produce, the requested information. Under the regulations, DTSC is also authorized to conduct audits to determine compliance with the AA and regulatory response requirements.
Next Steps

Following the controversy and criticism surrounding its "informal" draft regulations, DTSC's current formal proposed regulations are the culmination of four years of working with its Green Ribbon Science Panel, business groups, health care advocates, and environmentalists. DTSC will hold a public hearing on the proposed regulations on September 10, 2012. Responsible parties wishing to comment on the regulations now have until October 11, 2012 to do so.

Manufacturers will learn more about how this new regulatory program will work once the DTSC identifies the first batch of Priority Products and how they will be treated. The way they are handled will shed useful light on how manufacturers can best position themselves to comply with the Safer Consumer Products regulations even as they watch for DTSC to identify additional Priority Products.
