CALIFORNIA LEGISLATURE— 2023–2024 REGULAR SESSION

Assembly Bill
No. 234

Introduced by Assembly Member Bauer-Kahan

January 12, 2023

An act to add Chapter 5.8 (commencing with Section 42359) to Part 3 of Division 30 of the Public Resources Code, relating to solid waste.


LEGISLATIVE COUNSEL'S DIGEST


AB 234, as amended, Bauer-Kahan. Microparticles.
Existing law, the Plastic Microbeads Nuisance Prevention Law, prohibits a person from selling or offering for promotional purposes in the state any personal care products containing plastic microbeads that are used to exfoliate or cleanse in a rinse-off product, including, but not limited to, toothpaste.
This bill would enact the Synthetic Polymer Microparticles in Cosmetic and Cleaning Products Prevention Act. The bill would prohibit a synthetic polymer microparticle from being placed on the market in this state as a substance on its own or, where the synthetic polymer microparticles are present to confer a sought-after characteristic, in mixtures in a concentration equal to or greater than 0.01% by weight. The restriction would apply on and after specified dates depending on the type of product, as described, except as otherwise provided. The bill would specify the screening tests and pass criteria to be used for purposes of determining compliance with this prohibition. The bill would make a person who violates this prohibition liable for a civil penalty not to exceed $5,000 per day for each violation, in addition to any other penalty established by law. The bill would authorize the civil penalty to be assessed and recovered in a civil action brought by a city attorney, a district attorney, a county counsel, or the Attorney General in any court of competent jurisdiction.
Vote: MAJORITY   Appropriation: NO   Fiscal Committee: YES   Local Program: NO  

The people of the State of California do enact as follows:


SECTION 1.

 It is the intent of the Legislature to prohibit the sale in this state of cosmetics, detergents, waxes, and polishes that contain intentionally added synthetic polymer microparticles by aligning with those restrictions under the European Union’s Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) legislation.

SEC. 2.

 (a) For purposes of this chapter, all of the following apply:
(1) This section provides guidance for assessing the degradability of polymers for the purposes of entry to market: the permitted test methods and the pass criteria for those methods. The test methods were designed to measure biotic degradation, although some abiotic degradation may take place during the test and contribute to the test results.
(2) The biodegradability provisions apply only for the purpose of exempting biodegradable materials from the scope of this chapter.
(3) The tests described in subdivision (b) shall be conducted by laboratories complying with the principles of good laboratory practice provided for in Directive 2004/10/EC of the European Parliament and of the Council of the European Union or other international standards recognized as being equivalent or accredited to ISO 17025.
(4) The permitted test methods described in subdivision (b) are organized into five groups, on the basis of their design and underlying rationale. Meeting the pass criteria in any of the permitted test methods in groups 1 to 3, inclusive, as described in paragraph (1), (2), or (3) of subdivision (b), is sufficient to demonstrate that the polymer or polymers contained in the tested material and subject to the test are degradable and are therefore excluded from the scope of this chapter. If group 4 or group 5 tests, as described in paragraph (4) or (5) of subdivision (b), are used to demonstrate degradability of polymers for uses other than agricultural and horticultural uses, the pass criteria shall be met in at least three of the following environmental compartments:

(2) (A) (i) The group 2 permitted screening test methods are the following:
(I) The “Ready Biodegradability” test (OECD TG 301B, C, D, F).

(B)  The group 2 pass criteria to demonstrate ready biodegradation is 60 percent mineralization measured, over 60 days, as consumed O2, which shall be permitted only for the tests described in subclause (I) or (II) of clause (i) of subparagraph (A), or as evolved CO2. The 10-day window requirement mentioned in the test guidelines listed in subparagraph (A) do not need to be fulfilled.
(3) (A) The group 3 permitted test method is the “Inherent Biodegradability: Modified MITI Test (II)” test (OECD 302C). The preadaptation of the inoculum mentioned in the test guideline shall not be allowed.

(VI) Plastics - Determination of the aerobic biodegradation of non-floating materials exposed to marine sediment – Method by analysis of evolved carbon dioxide (ISO 22404:2019).
(ii) The specifications set forth in ISO 22403:2020 Plastics – Assessment of the intrinsic biodegradability of materials exposed to marine inocula under mesophilic aerobic laboratory conditions – Test methods and requirements shall be taken into account when applying subclauses (III) and (IV).
(iii) For group 4 test methods, the preadaptation of the inoculum shall not be allowed. The result shall be reported as the maximum level of degradation determined from the plateau phase of the degradation curve, or as the highest value if the plateau has not been reached. The form, size, and surface area of the reference material shall be comparable to that of the test material. Either of the following materials may be used as reference materials:

(A) OECD Guideline 120.
(B) OECD Guideline 105.
(3) The test material shall be comparable in terms of composition, form, size, and surface area to the polymer particles present in the product. For polymeric particles containing inorganic elements, such as particles encapsulated with inorganic substances or particles in which the polymer is grafted onto an inorganic carrier, it shall be sufficient to demonstrate that the polymeric part of the particle meets the pass criteria. This may require the testing of the polymer prior to the formation of the particle.

In accordance with OECD Test Guideline 120, this shall be determined by either of the following:
(A) One test concentration and direct analysis, by any appropriate means, to demonstrate that the polymer components in the aqueous phase comprise all molecular weight fractions present in the synthetic polymer microparticles.
(B) Two test concentrations and indirect analysis, by any appropriate means, for example, by determining total organic carbon of the aqueous phase and of the undissolved or not-extracted part, demonstrating comparable results at the high and the low test concentration.

42359.1.
 (a) A synthetic polymer microparticle shall not be placed on the market in this state as substances on their own or, where or if the synthetic polymer microparticles are present to confer a sought-after characteristic, in mixtures in a concentration equal to or greater than 0.01 percent by weight.
