Agenda

1. Welcome and Introductions
2. Review of Isoprene Cancer Inhalation Unit Risk Factor (IUR) – Technical Support Document for Cancer Potency Factors.
   

   Office of Environmental Health Hazard Assessment (OEHHA) staff will present a draft document summarizing the development of a cancer potency factor and an inhalation unit risk factor (IUR) for isoprene.  Cancer IURs are used to estimate lifetime cancer risks associated with inhalation exposure to a carcinogen. OEHHA is required to develop guidelines for conducting health risk assessments under the Air Toxics Hot Spots Program (Health and Safety Code Section 44360 (b)(2)). In response to this statutory requirement, OEHHA developed a draft IUR for isoprene. Workshops and comment period for the document were offered from February through April 2024. No public comments were received. More information regarding the Document is available.

3. Informational Item from OEHHA on Computational Toxicology and New Approach Methodologies for SRP.OEHHA is developing expertise in new approach methodologies (NAMS) to support CalEPA programs and regulatory activities. NAMS are new toxicological testing and analysis methods that allow for informed predictions of biological effects for data-poor environmental pollutants. There are several components to this effort, including the creation of the New Toxicology Evaluations Section within OEHHA and developing collaborations with academic organizations with NAMS expertise on data-poor compounds. The newly created section brings together experts in toxicology, bioinformatics, toxicokinetics and computational chemistry. This item will present an overview of the NAMS work at OEHHA and potential applications.
4. Consideration of administrative matters.
   The Panel may discuss various administrative matters and scheduling of future meetings.

The agenda items listed above may be considered in a different order at the meeting.

Information About The Scientific Review Panel

The Scientific Review Panel (Panel) is charged with evaluating the risk assessments of substances proposed for identification as toxic air contaminants by the California Air Resources Board (CARB), the Office of Environmental Health Hazard Assessment (OEHHA) and the Department of Pesticide Regulation (DPR), and the review of risk assessment guidelines prepared by OEHHA. In carrying out this responsibility, the Panel reviews the exposure and health assessment reports, and the underlying scientific data on which the reports are based, which are prepared by CARB, DPR, and OEHHA pursuant to Health and Safety Code sections 39660-39661, 39669.5 and 44360, and Food and Agricultural Code sections 14022-14023. These reports are prepared for the purpose of determining whether a substance or pesticide should be identified as a toxic air contaminant, or as guidelines to be used in preparing health risk assessments. The Panel is also to be consulted in the implementation of Assembly Bill 617 (H&SC sections 42705.5(b) and 44391.2; Chapter 136, Statutes of 2017).

The Panel welcomes written comments or submissions from all parties regarding reports that are under review. Although written comments are accepted up to the day of a scheduled meeting, to assure adequate review the Panel requests that written comments and information be submitted to the Panel Liaison (contact information below) as early as possible prior to a scheduled meeting. The Panel has discretion whether to accept oral public comment (Health & Safety Code § 39661 subd.(b)). The agenda will inform whether an item is open for oral public comment.

Transcripts to previously held Panel meetings and other information about the Panel can be found through the CARB web site.
