SEDIMENT SHALL BE DISPOSED OF OFF-SITE WHEN THE BAG IS 1/2 FULL AT A DUMP SITE

APPROVED BY THE ALLEGHENY COUNTY CONSERVATION DISTRICT.

VEGETATION

INSPECT ALL SEEDED AREAS WEEKLY AND AFTER EVERY RUNOFF EVENT. RESEED ALL

AREAS THAT VEGETATION HAS FAILED TO ESTABLISH. REPAIR ALL ERODED SLOPES, SEED

AND MULCH AS NECESSARY.

DISTURBED AREAS

AS SOON AS SLOPES, CHANNELS, DITCHES AND OTHER DISTURBED AREAS REACH FINAL

GRADE THEY MUST BE PERMANENTLY STABILIZED WITH A UNIFORM 70% PERENNIAL

VEGETATIVE COVER, STONE, OR PAVEMENT. TEMPORARY STABILIZATION SHALL BE

ESTABLISHED IN ANY AREAS WHERE CONSTRUCTION ACTIVITIES HAVE CEASED FOR FOUR

(4) DAYS OR MORE AND WHERE CONSTRUCTION ACTIVITIES WILL NOT RESUME WITHIN

FOUR (4) DAYS. A PERMANENT COVER SHALL BE INSTALLED IN ANY AREA WHERE

CONSTRUCTION IS TO BE HALTED FOR MORE THAN ONE YEAR. NO MORE THAN 15,000

SQUARE FEET OF DISTURBED AREA SHALL REACH FINAL GRADE BEFORE INITIATING

STABILIZED WITH SEED, MULCH, AND EROSION CONTROL BLANKET.

SEDIMENT DISPOSAL

ALL SEDIMENT TAKEN FROM THE EROSION CONTROL FACILITIES WILL BE SPREAD AND

DRIED FOR USE IN ONSITE GRADING OR DISPOSAL OFF SITE. UNSUITABLE MATERIAL SHALL

BE HAULED FROM THE SITE FOR PROPER DISPOSAL. AS CONSTRUCTION IS COMPLETED,

VEGETATION ESTABLISHED AND STABILIZATION MEASURES FINISHED, TEMPORARY

EROSION CONTROL FACILITIES WILL BE REMOVED.

PERMANENT CONTROL MEASURES WILL INCLUDE, BUT ARE NOT LIMITED TO: PERMANENT

SEEDING AND LANDSCAPING. THESE FACILITIES WILL BE IMPLEMENTED AND MAINTAINED

AS CONSTRUCTION IS COMPLETED. THE TOWNSHIP OF COLLIER WILL MAINTAIN THE

PERMANENT FACILITIES.

TOPSOIL APPLICATION

BEFORE THE SEEDING BEGINS, TOPSOIL SHOULD BE APPLIED AND ANY REQUIRED SOIL

AMENDMENTS WORKED INTO THE SOIL TO A DEPTH OF 4 TO 6 INCHES. IF COMPOST IS TO BE

ADDED TO THE TOPSOIL, IT SHOULD BE WORKED INTO THE SOIL WITH OTHER SOIL

AMENDMENTS UNLESS IT IS BEING APPLIED AS AN EROSION CONTROL BMP.

GRADED AREAS SHOULD BE SCARIFIED OR OTHERWISE LOOSENED TO A DEPTH OF 3 TO 5

INCHES TO PERMIT BONDING OF THE TOPSOIL TO THE SURFACE AREAS AND TO PROVIDE A

ROUGHENED SURFACE TO PREVENT TOPSOIL FROM SLIDING DOWN SLOPE.

TOPSOIL SHOULD BE UNIFORMLY DISTRIBUTED ACROSS THE DISTURBED AREA TO A DEPTH

OF 4 TO 8 INCHES MINIMUM -- 2 INCHES ON FILL OUTSLOPES. SPREADING SHOULD BE DONE

IN SUCH A MANNER THAT SODDING OR SEEDING CAN PROCEED WITH A MINIMUM OF

ADDITIONAL PREPARATION OR TILLAGE. IRREGULARITIES IN THE SURFACE RESULTING

FROM TOPSOIL PLACEMENT SHOULD BE CORRECTED IN ORDER TO PREVENT FORMATION OF

DEPRESSIONS UNLESS SUCH DEPRESSIONS ARE PART OF THE PCSM PLAN.

TOPSOIL SHOULD NOT BE PLACED WHILE THE TOPSOIL OR SUBSOIL IS IN A FROZEN OR

MUDDY CONDITION, WHEN THE SUBSOIL IS EXCESSIVELY WET, OR IN A CONDITION THAT

MAY OTHERWISE BE DETRIMENTAL TO PROPER GRADING AND SEEDBED PREPARATION.

COMPACTED SOILS SHOULD BE SCARIFIED 6 TO 12 INCHES ALONG CONTOUR WHEREVER

POSSIBLE PRIOR TO SEEDING.
