The e'�ements that are part of a Construction SWPPP are as follows: � � Q 1. Mark Clearing Limits:Prior to clearing or disturbing the limits must be marked.This element is j 6 i part of most normal construction plans as one of the first steps. 5 i 2. Establish Construction Access:All erosion control plans shall instal a stabilized construction d V Z ' p r X entrance(or other method of preventing sediment transport onto the roads).If a standard W 3 w i gravel construction entrance is proposed,use geo-textile fabric under the rock.Note:a _�a wheel wash is required for plans that propose winter grading. a a 0 0 W C 140 3. Detain Flows:Based on a downstream analysis it may be necessary to detain runoff from a 3 i C 150 site under construction.It may be necessary to construct and use a detention pond to 2 control flows during construction. o X 4. Install Sediment Controls:If there ls runoff from the construction site,sediment shag be removed from the water.Note that the water quality standards must be met. Q t _ 3 C 5. Stabilize Soils:All exposed and non-worked sod shag be stabT¢ed by use of BMP's.Note a, Zo there ore time periods of allowed exposure that depend on the season.Groundcover = N both temporary and permanent need to be pe part of the construction plans. p w y ^` N C Construct Stabilized Temporary _ i \ I6 6.
