CERTIFIED EROSION AND SEDIMENTATION CONTROL
The Washington State Department of Ecology requires all projects
disturbing over 1-acre of land to provide monitoring of stormwater
runoff. As a result, the DOE created the position of Cerfified
Erosion and Sediment Control Lead (CESCL).
Temporary Erosion Control Plans (TESC)
The
CESCL prepares the sedimention control plans for the project.
This involves the development of the TESC Plan, which is approved
by the governing agency prior to the start of construction. The
TESC Plan specifies the means and methods, locations, phasing and
maintenance of the erosion control facilities. Typical elements
of an erosion control plan include:
- Sedimentation and/or detention pond to clarify and attenuate stormwater runoff from the site.
- Silt fencing to intercept sediment-laden water
- Inlet protection
to prevent sediment discharge via existing storm drainage systems and
to keep pipes and catchbasins free of sediment accumulation
- Soil stabilization, including temporary and permanent seeding, terracing, surface roughening and mulching
Because
the critical need to prevent discharge of sediment - and the potential
for fines for violating water quality standards - it is important to
enlist the help of a qualified engineer to design, integrate and
coordinate the TESC measures on your project
