A recent release by the OEHHA on Di(n-butyl)phthalate (DBP):

Pursuant to the requirements of Government Code sections 11346.8(d), 11346.9(a)(1), and 11347.1, the Office of Environmental Health Hazard Assessment (OEHHA) is providing notice that documents and other information which the agency has relied upon in proposing amendments to Title 22, California Code of Regulations, section 12805*, have been added to the rulemaking file and are available for public inspection and comment.

On June 29, 2007, OEHHA published a Notice of Proposed Rulemaking (California Regulatory Notice Register, 2007, No. 26-Z, pages 1123-1125; Notice File No. Z-07-0619-02) to adopt regulatory levels for DBP pursuant to Title 22, California Code of Regulations, section 12805. The Initial Statement of Reasons set forth the grounds for the proposed regulation. Pursuant to the Notice of Proposed Rulemaking, a public comment period of 45 days was provided from the publication of the Notice until August 13, 2007. A total of three sets of written comments were received. These comments cited a number of publications that had not been previously included in the proposed rulemaking file (OAL Notice File No. Z-07-0619-02). In addition, a number of research or review papers became available to OEHHA after the draft MADL document was completed.

The purpose of this notice is to enter all relevant documents into the proposed rulemaking file (OAL Notice File No. Z-07-0619-02). All of the documents on the list below have been reviewed by OEHHA. None of these documents contributed directly to the development of the MADLs and were thus not cited in the main text of the document supporting the MADL (OEHHA, 2007). However, these papers have been reviewed by OEHHA and are sources of relevant information.
