(The Draft report Draft Report: Assessment of Children’s Exposure to Surface Methamphetamine Residues was added on 12/28/07.)
The Department of Toxic Substances Control (DTSC) and the Office of Environmental Health Hazard Assessment (OEHHA) are conducting joint public workshops for stakeholders and other interested parties on the development of the health-based target remediation standard (cleanup standard) for methamphetamine in residences used to illegally manufacture methamphetamine. Three workshops are scheduled:
Date: January 8, 2008
Time: 9:00 am to 1:00 pm
Location: Cal/EPA Headquarters Building
Sierra Hearing Room
1001 “I” Street, 2nd Floor
Sacramento, CA 95814
Note: Visitors must check-in with security upon entering the Cal/EPA Building
Date: January 16, 2008
Time: 9:00 am to 12:00 pm
Location: Woodward Park Regional Library Conference Room
944 East Perrin Avenue
Fresno, CA 93720
Date: January 29, 2008
Time: 12:30 pm - 4:30 pm
Location: Carlsbad Safety Center
2560 Orion Way
Carlsbad, CA 92008
All interested parties are invited to participate in one of these public workshops. Please note that the workshops may conclude earlier if the agenda items are completed.
Background: Under the provision of the Health and Safety Code Section 25400.16(c), DTSC, in consultation with OEHHA, is required to develop a health-based target remediation standard for surface methamphetamine contamination in residences that were used to illegally manufacture methamphetamine.
DTSC Objectives: DTSC is seeking comments regarding the development of the recommended methamphetamine cleanup standard for indoor surfaces in residences. Please refer to http://www.dtsc.ca.gov/SiteCleanup/ERP/Clan_Labs.cfm for additional information.
OEHHA Objectives: OEHHA is seeking formal comments on their draft reports that form the scientific basis for the development of the methamphetamine cleanup standard for residences that were used to illegally manufacture methamphetamine. Please refer to http://www.oehha.ca.gov to access the draft reports and other specific information regarding OEHHA’s reports.
In accordance with Health and Safety Code Section 57003, OEHHA is accepting public input at these workshops for the methamphetamine reference dose (RfD) and the exposure model/risk assessment used to develop the health-based cleanup standard. Public workshop commenters are urged to also provide their oral comments in writing. OEHHA will also accept all comments from the public provided in writing until 5:00 pm, February 29, 2008 to one of the following addresses or methods:
Mr. Leon Surgeon
Integrated Risk Assessment Branch
Office of Environmental Health Hazard Assessment
P.O. Box 4010, MS - 12B
Sacramento, California 95812-4010
Fax: (916) 322-9705
OEHHA will respond to all comments provided by the public and by external peer reviewers chosen by the process mandated in Health and Safety Code Section 57004. The responses will describe any changes made in revised drafts of the documents. The responses and revised drafts will be released for a second public review period. Comments from that review period will also be considered and responded to when the final documents are released.
Scientific Basis: Draft reports, developed by OEHHA, will form the basis for the standard that is intended to ensure safe human re-occupancy of the residence. Individuals are encouraged to review and comment on the two draft reports. In developing these documents, OEHHA has identified specific issues and concerns that are considered most important for comment and has also asked external peer reviewers to focus on these same issues and concerns for review and comment.
Draft Report: Development of a Reference Dose for Methamphetamine
This draft report describes the justification to support the primary study chosen to use as a basis for estimation of a sub-chronic RfD for methamphetamine. Topics for comments are as follows.
Draft Report: Assessment of Children’s Exposure to Surface Methamphetamine Residues in Former Clandestine Methamphetamine Labs, and Identification of a Risk-Based Cleanup Standard for Surface Methamphetamine Contamination
This draft report describes the procedures for estimating children's exposure to chemical contaminants on indoor surfaces and presents the calculations used to derive a risk-based surface cleanup standard for methamphetamine. Topics for comments are as follows.
