Announcement of a Public Comment Period and Workshops on the Draft
Report, "Proposed Methodology for Calculating Advisory
Human-Exposure-Based Screening Numbers Developed to Aid Estimation of
Cleanup Costs for Contaminated Soil"

The Office of Environmental Health Hazard Assessment (OEHHA) of the
California Environmental Protection Agency announces the availability of
the draft report, "Proposed Methodology for Calculating Advisory
Human-Exposure-Based Screening Numbers Developed to Aid Estimation of
Cleanup Costs for Contaminated Soil," and two workshops to present the
methodology to the interested public for review and comment. This draft
report is required by the California Land Environmental Restoration and
Reuse Act (Escutia, Chapter 764, Statues of 2001) as part of the effort
to develop soil screening numbers for a specific set of contaminants.
The Act identifies a screening number as solely an advisory number, and
has no regulatory effect. The screening numbers are intended to enable
citizen groups, community organizations, property owners, developers,
and local government officials to estimate the degree of effort that may
be necessary to remediate a contaminated property. This document does
not discuss how the public and government agencies might apply these
screening numbers, once they are developed. The document is limited to
the technical basis that will be used to compute the screening numbers.

Two workshops will be held to describe the proposed methodology to
derive screening numbers and take comments. Examples are presented in
the document to show how the screening are derived by the methodology
and are not being presented as the final screening numbers. These
workshops will be held on the dates and at the times and locations below:

April 6, 2004
1:30 PM to 3:30 PM
California Environmental Protection Agency Headquarters Building
Sierra Hearing Room, Second Floor
1001 I Street
Sacramento, California

April 7, 2004
1:00 PM to 3:00 PM
Ronald Reagan State Building
Auditorium, First Floor
300 South Spring Street
Los Angeles, California

Comments on the proposed methodology are welcomed by mail and at the
workshops. To ensure we have an accurate record of all comments, we
request your oral comments at the workshops also be provided in writing.
The comment period will be from March 12 to April 16, 2004. Please have
all comments mailed or faxed by 5:00 PM on April 16, 2004. Comments
