Sediment TMDL Implementation
Approximately 61% of the North Coast Region drains to rivers and streams
that are impaired by too much sediment (2006 Clean Water Act Section 303(d)
list).
Sediment TMDL Implementation Policy
As part of our efforts to control sediment waste discharges and restore sediment
impaired water bodies, the Regional Water Board adopted the Total Maximum Daily
Load Implementation Policy Statement for Sediment Impaired Receiving Waters
in the North Coast Region, which is also known as the Sediment TMDL Implementation
Policy, on November 29, 2004. This Policy was adopted through Resolution
R1-2004-0087.
The Sediment TMDL Implementation Policy states that Regional Water Board
staff shall control sediment pollution by using existing permitting and enforcement
tools. The goals of the Policy are to control sediment waste discharges
to impaired water bodies so that the TMDLs are met, sediment water quality
objectives are attained, and beneficial uses are no longer adversely affected
by sediment.
The Sediment TMDL Implementation Policy also directs staff to develop: (1)
the Work Plan, that describes how and when permitting and enforcement tools
are to be used; (2) the Guidance Document on Sediment Waste Discharge Control;
(3) the Sediment TMDL Implementation Monitoring Strategy; and (4) the Desired
Conditions Report.
The following Sediment TMDL Implementation Policy documents are available:

Policy, please contactLisa Bernard at 576-2677 or Lisa.Bernard@waterboards.ca.gov.
Work Plan
Guidance Document for the Control of Excess Sediment Discharges
The Guidance Document will include examples of excess sediment discharge
sites, sediment control practices, road management practices, and sediment
assessment methods. It will also contain suggested content for a comprehensive
inventory, prioritization, and sediment control plan. Monitoring guidance
may also be included.
The Guidance Document is under development. It will be presented to
the Board upon completion.
For information, comments, and questions on the Guidance Document, please
contact Lisa Bernard at 576-2677 or Lisa.Bernard@waterboards.ca.gov.
Sediment TMDL Implementation Monitoring Strategy
The Monitoring Strategy is needed to provide feedback on the recovery of
sediment-impaired water bodies and the success of the Sediment TMDL Implementation
Strategy and efforts to reduce excess sediment discharges. It will include
monitoring objectives, the locations of trend monitoring stations, a description
of the parameters to be monitored, benchmark conditions, measurable milestones,
and specific due dates for monitoring and data analysis.
The Monitoring Strategy is under development. It will be presented
to the Board upon completion, which is expected in late 2008.
For information, comments, and questions on the Monitoring Strategy, please
contact Rich Fadness at 707-576-6718 or rfadness@waterboards.ca.gov.
Desired Conditions Report
The full title is the Desired Salmonid Freshwater Habitat Conditions for
Sediment-Related Indices. The Report describes the conditions that are
expected to support the beneficial uses associated with the cold water fishery
and meet the narrative sediment water quality objectives in regards to salmonid
freshwater habitat.
The Desired Conditions Report was completed in July 2006. The Report
has been peer reviewed and a response to public comments was prepared. Staff
are currently working on an update to the Report with possible changes to the
benthic macroinvertebrate assemblage and embeddedness desired conditions.
The following Desired Conditions Report documents are available:
For information, comments, and questions on the Desired Conditions Report,
