3.0 EROSION AND STORMWATER CONTROL PLAN
Silo 3 Environmental Control Plan
40430-PL-0005, Rev. C
Jacobs Project Number 35H19605
September 23, 2003
This section describes the Erosion and Stormwater Control Plan that will be used during
the construction phase of the Silo 3 Project, including erosion control practices and
surface water management. This Plan addresses surface water management and erosion
control practices throughout the construction of the Silo 3 process facilities and the Silo 3
enclosure and is consistent with the construction drawing and Silo 3 specifications. See
drawing 94X-3900-G-01298 (G3105).
3.1 FUNCTIONAL REQUIREMENT OF THE PLAN
The functional requirements of this Erosion and Stormwater Control Plan will satisfy the
criteria outlined below:
Route surface water to designated locations where it can be appropriately managed;
Protect the Infrastructure Road, 2”d Street, Silo 3 and construction areas from damage
caused by precipitation and stormwater run-on and runoff;
0 Discharge surface water into existing watercourses in accordance with applicable Ohio
Department of Natural Resources (ODNR), OEPA and DOE directives and requirements;
and
Segregate clean area runoff from potentially contaminated area runoff. Contaminated
stormwater will not be discharged with “clean“ stormwater.
Functional requirements will be met by constructing the run-onhunoff control features
outlined below. Erosion control features will be installed prior to any disturbance of soil in
work areas. The Civil Grading, Drainage and Erosion Control Plan, drawing 94X-3900-G-
01 298(G3105), illustrates the location and limits of the control features. These include,
but are not limited to, the following six control features:
0 Installation of silt fences on the downslope sides of the construction areas;
Installation of silt fences below sump discharges where applicable;
Installation of check dams in drainage channels and swales as required;
0 Maintenance, repair, or replacement of existing surface water and erosion control
features as required;
5069
Excavations that are expected to be inactive for 45 days or more will be stabilized
within 7 days of their final use; and
a Dewatering.
