Extension of Public Comment Period for the Proposed Reference Exposure Levels for Toluene
The Office of Environmental Health Hazard Assessment (OEHHA) released a draft document, Toluene Reference Exposure Levels, for a 60-day public review period on December 1, 2017. OEHHA received a request from the American Chemistry Council Toluene & Xylene Panel to extend the public comment period. This notice extends the comment period to February 14, 2018.
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 develops RELs for many air pollutants. The toluene Reference Exposure Levels were developed using the most recent “Air Toxics Hot Spots Program Technical Support Document for the Derivation of Noncancer Reference Exposure Levels,” finalized by OEHHA in 2008.
After the close of the public comment period, the documents will be revised as appropriate by OEHHA, and peer reviewed in 2018 by the State’s Scientific Review Panel on Toxic Air Contaminants.
