STOCKPILES:
1.
ALL ON -SITE TOPSOIL MUST BE PRESERVED FOR REUSE ON THE SITE DURING REVEGETATION, UNLESS
IT IS INFEASIBLE OR UNREASONABLE TO DO SO. (NOTE: TOPSOIL STOCKPILING ON -SITE MAY
BE
INFEASIBLE IF SPACE IS NOT AVAILABLE ON -SITE FOR TOPSOIL STOCKPILING OR IF LITTLE
TO NO
VEGETATION IS TO REMAIN UNDER POST -CONSTRUCTION CONDITIONS. STOCKPILING OF TOPSOIL
AT
AN OFF -SITE LOCATION OR TRANSFER OF TOPSOIL TO OTHER LOCATIONS MAY ALSO BE ACCEPTABLE
BUT MUST BE AUTHORIZED BY ENGINEER). CONTRACTOR IS RESPONSIBLE FOR ANY NECE
SARY
OFF -SITE PERMITTING, INCLUDING LAND DISTURBANCE.
2.
ALL SOIL STOCKPILES MUST BE STABILIZED TO PREVENT EROSION AND FUGITIVE DUST.
THE
SURFACE OF THE STOCKPILE MUST BE PROPERLY PROTECTED TO ELIMINATE THE RISK OF EROSION.
SEE TEMPORARY SEEDING OR STABILIZATION DETAIL. SUITABLE ALTERNATIVE MEANS
OF
STABILIZATION CAN BE USED, SUCH AS PROPERLY ANCHORED PLASTIC TARPS.
3.
PERIMETER SEDIMENT CONTROLS ALSO MUST BE INSTALLED AT STOCKPILE LOCATIONS TO PREVENT
CONTACT WITH STORMWATER, INCLUDING RUN-ON.
4.
STOCKPILES MUST BE LOCATED OUTSIDE OF ANY VEGETATED BUFFER AREAS AND SHOULD BE

CONTRACTOR SHALL TEMPORARILY AND PERMANENTLY STABILIZE FILL SLOPES AS SOC_}N AS
POSSIBLE.
DUST CONTROL:
1. LARGE AREAS OF SOIL THAT ARE DENUDED OF VEGETATION AND HAVE NO PROTECTION FROM
PARTICLES BEING PICKED UP AND CARRIED BY WIND SHOULD BE PROTECTED WITH N TEMPORARY
COVER OR KEPT UNDER CONTROL WITH WATER OR OTHER SOIL ADHERING PRODUCTS TO PREVENT
SOIL PARTICLES FROM BECOMING AIRBORNE, AND FROM EXITING THE SITE PERIMETER,
2. WATER TRUCKS OR OTHER DUST CONTROL AGENTS SHALL BE USED AS NEEDED DURING
CONSTRUCTION TO MINIMIZE DUST GENERATED ON THE SITE. TACKIFIERS MAY BE USED TO HOLD
SOIL IN PLACE AND PREVENT DUST. MANUFACTURER RECOMMENDATIONS FOR APPLICATION
LOCATIONS AND RATES MUST E USED FOR DUST CONTROL APPLICATIONS. ONLY SWF PP -SPECIFIED
L B 0
TACKIFIERS MAY BE USED ON THE PROJECT SITE; ANY CHEMICAL APPLICATION NOT INCLUDED IN THE
SWPPP MUST BE APPROVED, IN WRITING, BY THE ENGINEER.
3. DUST CONTROL MUST BE PROVIDED BY THE GC TO A DEGREE THAT IS IN COMPLIANCE WITH
APPLICABLE FEDERAL, LOCAL AND STATE DUST CONTROL REGULATIONS.

3. THE SITE HAS ACHIEVED FINAL STABILIZATION ONCE ALL AREAS ARE COVERED WITH BUILDING
FOUNDATION OR PAVEMENT, OTHER LANDSCAPING COVER (STONE, MULCH, ETC.), OR NAVE A STAND
OF GRASS WITH A MINIMUM OF 70 PERCENT DENSITY OVER THE ENTIRE VEGETATED AREA, OR
GREATER IN ACCORDANCE WITH THE GENERAL PERMIT REQUIREMENTS.
4. VEGETATED AREAS MUST BE WATERED, FERTILIZED, AND RESEEDED AS NEEDED TO ACHIEVE THIS
REQUIREMENT.
5. THE VEGETATION DENSITY MUST BE MAINTAINED THROUGH THE PROJECT COMPLETION TO BE
CONSIDERED STABILIZED. AREAS PROTECTED BY EROSION CONTROL BLANKETS ARE NOT
PERMANENTLY STABILIZED UNTIL THE APPLICABLE GENERAL PERMIT REQUIREMENT FOR FINAL
VEGETATIVE DENSITY IS ACHIEVED.
6. RIP -RAP, MULCH, GRAVEL, DECOMPOSED GRANITE OR OTHER EQUIVALENT PERMANENT STABILIZATION
MEASURES MAY BE EMPLOYED IN LIEU OF VEGETATION BASED ON SITE -SPECIFIC CONDITIONS, DESIGN
AND GOVERNING AUTHORITY APPROVAL.
7. ALL SEEDED AREAS SHALL BE INSPECTED REGULARLY TO CONFIRM THAT A HEALTHY STAND OF
