WVE/BCPP coalition post-passage summary letter — California SB 258 (Lara) Cleaning Product Right to Know Act of 2017

This is a one-page post-passage summary letter circulated by Women’s Voices for the Earth (WVE) and Breast Cancer Prevention Partners (BCPP) following Governor Edmund G. Brown Jr.’s 15 October 2017 signature of California SB 258, the Cleaning Product Right to Know Act of 2017. The letter is the campaign’s brief post-signature communication: it announces passage, identifies the four co-sponsor organisations and the broader supporter coalition, lists three statutory elements considered most consequential by the co-sponsors, and points readers to BCPP and WVE for follow-up. The letter is signed by Jamie (WVE) and by Nancy & Janet (BCPP). NRDC and EWG are identified in the letter body as co-sponsors but do not sign the letter.

The letter is a separate document from the pre-passage WVE factsheet held elsewhere in the same Kimi-corruption corpus folder. The factsheet was a two-page advocacy document distributed during the legislative campaign before passage; the present letter is a one-page communication distributed after Governor Brown’s signature. The two documents differ in one substantive numeric detail: the pre-passage factsheet states that the SB 258 confidential-business-information (CBI) carve-out references 22 authoritative lists of chemicals of concern, whereas the present post-passage letter states that the carve-out references 23 hazard lists. The post-passage figure is the binding one — by the time the letter was written, the final enrolled statute had been signed and its hazard-list count was fixed — but the discrepancy with the pre-passage factsheet is documented here for traceability and is left for downstream regulation-page work (Cal. Health & Safety Code §§ 108950–108997 implementation analysis) to resolve against the binding statutory text and the California Department of Toxic Substances Control’s (DTSC’s) implementing materials.

Heavy-metal relevance is indirect and operates via the same mechanism documented on the sibling pages: the SB 258 CBI carve-out, by referencing the 23 hazard lists, sweeps in heavy metals to the extent they appear on any of those lists (CA Prop 65, CA MCLs, IRIS, IARC, NTP, ATSDR, US EPA PBTs, OEHHA Non-Cancer Hazards, and the additional DTSC-curated lists under the Safer Consumer Products Regulations chemical inventory, plus the European Union list of fragrance allergens). The letter does not enumerate the 23 lists, does not name any specific heavy metal, and does not propose any quantitative threshold for any chemical in any product matrix. It is held in the Heavy Metal Index corpus as a regulatory-context citation for the SB 258 framework — a post-passage record of the co-sponsors’ framing of the enacted bill — and not as a primary source for heavy-metal exposure values.

Key numbers

The letter reports no contamination measurements and no heavy-metal data. The reportable quantitative content is summarised below.

Statutory thresholds described (page 1)

The 100 ppm fragrance-disclosure threshold is the first quantitative threshold present in the SB 258 documentary record in the HMI corpus (the sibling pre-passage factsheet does not state a numeric threshold). The threshold is the disclosure trigger for fragrance ingredients generally; it does not apply to fragrance ingredients that appear on any of the 23 hazard lists, which must be disclosed at any level under the carve-out. The letter does not specify whether the 100 ppm threshold is mass/mass, mass/volume, or another basis; the binding statutory text at Cal. Health & Safety Code §§ 108950–108997 carries the operative basis definition.

Statutory provisions described (page 1)

Coalition composition (described in narrative)

The letter identifies WVE, BCPP, NRDC, and EWG as the four co-sponsors of the bill. It identifies a broader supporter coalition of advocacy organisations and labour groups, and a separate corporate-supporter group described as “international cleaning product manufacturers and their trade associations” comprising several large consumer-cleaning multinationals, a fragrance house, and a major trade association. The corporate-supporter and consumer-brand-supporter enumerations from the letter body are not reproduced on this source page per the Part 12 brand firewall (strict reading); the PDF in raw/ carries the names if downstream regulation-page work needs the enumeration.

Methods (brief)

Not applicable. This is a one-page coalition post-passage summary letter, not an experimental study, surveillance dataset, or regulatory text. There is no sampling, no analytical instrumentation, no measurement of any kind. The “method” content of the letter is its summary of the enacted bill’s three highlighted statutory elements (label disclosure, the 100 ppm fragrance threshold tied to the 23 hazard lists, and the hazard-list-tied CBI restriction) and its identification of contact points at WVE and BCPP for follow-up.

Bill provenance. SB 258 was introduced by California Senator Ricardo Lara on 2 February 2017; passed the State Senate and the State Assembly during the 2017 session; and was signed into law by Governor Edmund G. Brown Jr. on 15 October 2017 as Chapter 830, Statutes of 2017. The statutory text is codified at Cal. Health & Safety Code Division 104, Part 3, Chapter 13 (§§ 108950–108997). The letter is internally consistent with a mid-to-late October 2017 distribution date (“Last weekend Governor Jerry Brown signed SB 258”); the letter PDF itself carries no explicit date and no header date stamp.

Speciation. Not applicable. No heavy metals named.

Basis. Not applicable. No concentration values for any chemical in any matrix. The 100 ppm fragrance threshold is the only numeric concentration in the document and applies generically to fragrance ingredients without a basis qualifier.

Implications

• The letter is the post-passage co-sponsor record for California SB 258. Together with the sibling pre-passage coalition factsheet, it brackets the legislative-advocacy cycle for the Cleaning Product Right to Know Act: factsheet during the campaign, summary letter after signature. Both are held in the Heavy Metal Index corpus as regulatory-context citations for the SB 258 framework.
• The letter is the first document in the SB 258 corpus to carry a numeric statutory threshold — the 100 ppm fragrance-disclosure trigger, modulo the hazard-list-tied carve-out. The hazard-list carve-out is the mechanism by which the disclosure framework reaches heavy metals: where a heavy metal is named (as element or compound) on any of the 23 hazard lists, a California-sold cleaning product containing that heavy metal cannot withhold its presence as CBI, regardless of concentration.
• The 22-versus-23 hazard-list discrepancy between the pre-passage factsheet and the post-passage letter is recorded here for downstream traceability. The post-passage figure (23) is the binding count; the discrepancy is treated as a pre-passage drafting artefact. The authoritative enumeration of the 23 hazard lists lives in DTSC’s implementing materials and in the final statutory text at Cal. Health & Safety Code §§ 108950–108997, not in either coalition document.
• The letter does not propose any heavy-metal threshold for any cleaning product. No HMTc-relevant threshold value can be drawn from this source. The 100 ppm fragrance threshold is a disclosure trigger, not a contamination limit, and applies to fragrance ingredients generally rather than to heavy metals specifically.
• The SB 258 framework, in combination with the New York DEC disclosure framework under ECL Article 35 and 6 NYCRR Part 659.6, comprises the two US state-level mandatory cleaning-product ingredient-disclosure regimes documented in the Heavy Metal Index corpus. The two frameworks differ structurally: SB 258 operates via a hazard-list-tied CBI carve-out with a 100 ppm general fragrance-disclosure trigger; the NY DEC framework operates via an ingredient-classification taxonomy (intentionally added / fragrance / nonfunctional byproduct / nonfunctional contaminant) with a five-step threshold hierarchy for the contaminant class.

Limitations

• No original measurements and no heavy-metal data. The letter reports no contamination values, no analytical methods, no detection frequencies, no heavy-metal concentrations or thresholds. The corpus value is regulatory-context only.
• One-page coalition communication, not regulatory text. The letter is the co-sponsors’ brief post-passage communication, not the binding statutory text. The three statutory elements it describes are paraphrases of the enacted bill rather than the operative codification. Wiki sessions needing the binding statutory text should consult Cal. Health & Safety Code §§ 108950–108997 directly.
• Heavy-metal applicability is indirect. The letter does not name any heavy metal. Heavy-metal capture by SB 258 is mediated by the 23 hazard lists; the letter describes the existence of the 23-list mechanism but does not enumerate the lists or identify which contain heavy metals.
• 23 lists not enumerated. The letter states that the CBI carve-out references “23 hazard lists” but does not provide the enumeration. The authoritative enumeration is in DTSC’s Safer Consumer Products Regulations implementing materials; that material is not part of the present source page.
• 22-versus-23 discrepancy with pre-passage factsheet. The pre-passage coalition factsheet states 22 lists; the post-passage letter states 23 lists. The post-passage count is the binding one but the discrepancy is unresolved at the coalition-document layer and would need DTSC-implementing-material review to confirm.
• Coalition advocacy posture, not independent analysis. The letter was prepared by two of the four bill co-sponsors. Evidence-tier C is appropriate to reflect the document’s coalition-communication posture; the underlying statutory text and DTSC implementing materials are the authoritative regulatory anchors.
• No publication date in document body. The letter PDF carries no explicit publication date. The 2017 year is set on the basis of the internal reference “Last weekend Governor Jerry Brown signed SB 258” (Governor Brown signed the bill on 15 October 2017), placing distribution in mid-to-late October 2017.

Verification notes

• Identity-check results on 2026-06-09 against wiki/sources/: DOI null (NGO coalition communication, no DOI assigned); raw_handle grep for MFK_california-sb258-right-to-know-summary returned no matches; cite-key grep for wve2017 / sb258 / right-to-know-summary returned no matches. The sibling bcpp2017-ca-sb258-factsheet page exists and is a distinct document (the pre-passage factsheet); the present letter is the post-passage summary, explicitly enumerated by the factsheet’s own Provenance section as the separately-processed companion. Ingested as NEW.
• SHA-256 of the source PDF computed from disk on 2026-06-09: 40dfc72df0d727ad7377eb5521beeafb8429fd50fe8a51c90f33fe66d409357e.
• The document has no DOI (NGO coalition communication). doi is null.
• Year set to 2017 on the basis of (i) internal reference “Last weekend Governor Jerry Brown signed SB 258” (Governor Brown signed on 15 October 2017), placing distribution in mid-to-late October 2017, and (ii) consistency with the post-passage advocacy timeline. The letter PDF itself carries no explicit date.
• Authors set to the two signatory organisations (WVE and BCPP) in the order in which the signatures appear in the letter body (“Jamie, Women’s Voices for the Earth” then “Nancy & Janet, Breast Cancer Prevention Partner”). The letter identifies four co-sponsors (WVE, BCPP, NRDC, EWG) in its body, but NRDC and EWG do not sign. Cite-key uses wve2017 to reflect signature lead order, distinguishing this page from the sibling bcpp2017-ca-sb258-factsheet page whose factsheet header carries the four-organisation logo strip starting with BCPP.
• Evidence tier set to C on the basis of: (i) the document is a one-page coalition post-passage communication, not a primary regulatory text, not a peer-reviewed study, and not an independent expert analysis; (ii) the authors are two of the four bill co-sponsors; (iii) the three statutory elements described are paraphrases rather than the binding statutory text; (iv) heavy-metal applicability is indirect via the 23 hazard lists (not enumerated in the letter). Tier C matches the sibling pre-passage factsheet and the davidsuzuki2014-toxic-household-cleaners sibling NGO-educational document in the same corpus folder.
• Source type set to ngo-advocacy to match the sibling factsheet’s classification. The letter is from coalition co-sponsors and frames the enacted bill in their advocacy voice; classifying it under the same source_type as the factsheet maintains routing consistency across the SB 258 documentary record.
• License set to a coalition-authored-public-distribution string matching the sibling factsheet’s framing.
• metals: [] is intentional: the letter does not name any heavy metal in body text, headers, or footnotes. Pb, Cd, As, Hg, Cr-VI, Ni capture by SB 258 is mediated indirectly through the 23 hazard lists, but the letter itself does not enumerate which heavy metals are captured by which lists. Routing fan-out to metals/* pages is therefore not asserted at the source-page level.
• ingredients: [] is intentional: the letter is a generic disclosure-framework communication; no specific ingredient is named in scope.
• products: ["[[products/household-specialty-cleaners-other]]"] uses the broadest available scope. The letter scopes the statute as “household and institutional cleaning products” without enumerating specific product subcategories. Per the verification-checklist scope rule (“Scope is broad, not narrow”), the present page asserts only the umbrella slug. The sibling pre-passage factsheet enumerates nine specific product subcategories because its body text lists them by name (“detergents, glass cleaners, carpet cleaners, stain removers, air fresheners, all-purpose cleaners and more”); the present letter does not. Routing fan-out is regulatory_context because no contamination values are reported.
• matrices: [household-cleaning-product] matches the sibling factsheet and the four other regulatory-context source pages in the same corpus folder.
• jurisdictions: [US-CA] because the letter discusses California state legislation. No other jurisdiction is asserted.
• Wiki/HMTc firewall (Part 2): the letter is upstream of any HMTc threshold-setting work and does not propose any quantitative limit on any chemical in any product matrix. The 100 ppm fragrance-disclosure threshold is a disclosure trigger, not a contamination limit. No Part 2 drift risk.
• Brand firewall (Part 12, strict reading 2026-05-17): the letter names several international consumer-cleaning multinationals, a fragrance house, a specialty/automotive-lubricant manufacturer, a major trade association, and two consumer cleaning brands as supporters of the bill, plus four advocacy organisations and one labour union as coalition supporters. The corporate-supporter names and the two consumer-brand-supporter names are NOT reproduced in the body of this source page. Part 12 Exception 1 (regulatory-event subject) is the closest carve-out, but its operative scope is enforcement actions and Congressional investigations where the brand is the subject of agency action — not bill-supporter rosters. To stay clean of HMT&C-defensibility risk that any future plaintiff’s expert could re-frame as “the wiki lists brands by their relationship to cleaning-product regulation,” the strict reading is applied: the support-coalition descriptors are summarised by category (international cleaning product manufacturers, trade association, fragrance house, advocacy organisations, labour union, consumer-brand supporters) without enumerating names. The PDF in raw/ carries the names if downstream regulation-page or DTSC-implementing-material work needs the enumeration. The NGO co-sponsor names (WVE, BCPP, NRDC, EWG) are reproduced because those organisations are the authors of the document, not brand subjects of measurement.
• The pre-passage factsheet states the CBI carve-out references “22 authoritative lists”; this post-passage letter states “23 hazard lists.” This is the one substantive numeric discrepancy between the two coalition documents. The post-passage figure (23) is the binding count by virtue of being closer to the enacted statutory text. The discrepancy is recorded in body text and Limitations for traceability and is left for downstream regulation-page work to reconcile against the binding Cal. Health & Safety Code §§ 108950–108997 text and DTSC’s implementing materials.
• Quantitative content in this page (100 ppm fragrance-disclosure threshold, 23 hazard-list count, statutory-provision quotations) is reproduced exactly from the source PDF.
• No new ingredient pages, no new product pages, no new regulation pages were created during this ingest, per CLAUDE.md Part 10 and the skill’s hard constraints.
• If a regulations/ca-sb258-cleaning-product-right-to-know.md page is ever created (Step 0 Lock decision), this post-passage letter and the sibling pre-passage factsheet would together be the principal coalition-document citations, with the binding statutory text at Cal. Health & Safety Code §§ 108950–108997 as the regulatory anchor and DTSC’s implementing materials as the source for the 23 hazard lists.
