Engineering Performance Standards Fact Sheets
Engineering Performance Standards (EPS) Information Basics Documents
|
General
Overview
The objectives and intended use of engineering performance
standards, the process for developing engineering performance standards
and the public’s role in that process are described in: this document.
Dredging Resuspension
The resuspension standard is designed to protect water
intakes down river of dredging operations and to limit the down river
transport of PCB-contaminated dredged material. This will promote the
recovery of the river ecosystem after dredging.
Dredging Residuals
The performance standard for dredging residuals will be used to
measure whether the objectives for residual PCB concentrations established
in the ROD have been achieved. Sediment samples will be collected and
analyzed for PCBs after dredging is completed in a given area. The results
will then be compared with cleanup goals and other criteria. If PCB contamination
is found at unacceptable levels, appropriate action, such as capping or
redredging, will be required.
Dredging Productivity
The dredging productivity standard is designed to maintain the
pace of removing an estimated 2.65 million cubic yards of sediment to
meet the six-year schedule for completing the dredging operation. It defines
the amount of sediment to be dredged by the end of each project phase
and dredging season. The standard also specifies minimum and target amounts
of sediment to be removed, and requires the monitoring of monthly sediment
removal goals.
Summary of Changes from May 2003 EPS -Public
Review Copy
The Draft Engineering Performance Standards - Public Review Copy
document was revised based on public comment and became what is referred
to as the Draft Engineering Performance Standards - Peer Review Copy document.
In October 2003 EPA submitted the Draft
Engineering Performance Standards – Peer Review Copy document
for peer review. It contains the draft engineering performance standards
that are being peer reviewed by a panel of independent experts. A summary
of the changes from the May 2003 Public Review Copy document can be found
in the above fact sheet.
