Stormwater Permit - Ready Mix Plant - Pamlico County
Subject: Stormwater Permit eady Iylix Plant'=Pamlico County

Hey to Kevin, Joe and the Secretary that makes you guys look good:
This message is for Kevin. I drafted the stormwater permi`(SWZfor the Ready Mix Plant
located at Alliance; it is dated for Monday 4/30.
1 have a couple of issues that need to be addressed.
(1) Vegetation Plan needs to be modified: you can provide a plan similar to the New Building Supply
project (see Joe) that issued in late February, this year; or you can put together a new plan, with details
shown, that incorporates all the current knowledge/information found in the DWQ - Draft BMP document
on our website. I expect that we will require more fonnal/written/detailed vegetation plans in the very
near future. Hopefully, DWQ will provide some written guidance, in addition to the info in the BMP
manual.
(2) Truck Wash Down Area: Explain how truck wash down area will be used; will wash water receive
some treatment before being routed to the wet pond; should the truck wash down area be located further
away from the pond inlet (maximize the flow length through grass swales). I hope the owners plan to
have a separate pit, or wash down area, to handle the bulk of the waste concrete residue. Significant
amounts of wastewater discharged into the stormwater pond could cause serious problems. Please
address.
If you have some questions, call me at 948-3919; I will be in Thursday.

4.REVEGETATE ALL DISTURBED AREAS IN ACCORDANCE
WITH THE PROJECT VEGETATION PLAN, SEE
DETAIL G, SHEET C4.
MAINTENANCE PLAN:
1. ALL EROSION AND SEDIMENTATION CONTROL DEVICES SHALL
BE CHECKED FOR STABILITY AND OPERATION FOLLOWING
EVERY RUNOFF -PRODUCING RAINFALL EVENT AND IN NO
CASE LESS THAN ONCE EVERY WEEK. ANY NEEDED
REPAIRS WILL BE MADE IMMEDIATELY TO MAINTAIN ALL
DEVICES IN THE OPERATING CONDITIONS INTENDED.
2. ALL AREAS WILL BE SEEDED, FERTILIZED, AND RESEEDED
AS NECESSARY AND MULCHED ACCORDING TO
SPECIFICATIONS IN THE VEGETATION PLAN IN ORDER TO
ESTABLISH AND MAINTAIN A VIGOROUS, DENSE VEGETATIVE
COVER.
3. ANY SEDIMENT TRACKED ONTO THE ADJACENT PUBLIC
ROAD SHALL BE REMOVED ON A DAILY BASIS.
4. SEDIMENT SHALL BE REMOVED FROM BEHIND SILT FENCING
& CHECK DAMS WHEN THE SEDIMENT ACCUMULATES TO
A DEPTH OF ONE FOOT.
5 THE STORMWATER RETENTION POND SHALL BE CLEANED OF
ANY ACCUMULATED SEDIMENT UPON THE COMPLETION OF
CONSTRUCTION.

NOTES:
1. CONSTRUCT CHECK IAM OF RIP
RAP STONE PLACED IN ACCORDANCE
WITH DETAIL.
2. SEDIMENT BEHIND THE CHECK DAM
SHALL BE REMOVED ONCE THE LEVEL
IS WITHIN 6" OF THE (lNTERLINE
CREST OF THE DAM.
3. SHOULD SCOUR DEV=LOP AT THE
DOWNSTREAM END, IT ;HALL BE
REPAIRED IMMEDIATELY.
4. PROVIDE 12" MIN. FNE GRAVEL
ON UPSTREAM END OFCHECK DAM.
VEGETATIVE SEEDING
AFTER COMPLETION OF GRADING ACTIVITIES ANF) THE
CONSTRUCTION OF SWALES, ALL EXPOSED ARFAS SHALL
BE SEEDED TO THE FOLLOWING SPECIFICATIONS:
SEED BED
LIME 1-1/2 TON PER ACRE
FERTILIZER 1/2-TON PER ACRE
SEED
RYE GRAIN 50 LBS PER ACRE
TALL FESCUE 100 LBS PER ACRE
MAY THROUGH AUGUST:
CENTIPEDE 5 LBS PER ACRE
PROCEDURE
STRAW MULCH SHALL BE APPLIED AT A RATE WHICH WILL
INSURE APPROXIMATELY 75% COVERAGE OF THE SEEDED
AREA. THE STRAW AND SOWN SEED WILL BE LICHTLY
DISCED INTO THE BED TO GIVE IT FURTHER RESISTENCE
TO BLOWING AND WASHING.
THE CONTRACTOR SHALL GUARANTEE A FULL STAND OF
GRASS OVER THE ENTIRE DISTURBED AREA. IF NECESSARY
THE CONTRACTOR WILL WET DOWN THE AREAS TO ASSIST
IN SEED GERMINATION OR AID IN GROWTH IN TIMES OF
EXCESSIVELY DRY WEATHER. A STAND OF GRASS WILL BE
CONSIDERED ACCEPTABLE WHEN THE ENTIRE STAND OF
GRASS IS AT LEAST FOUR INCHES HIGH AND HAS
ACHIEVED AT LEAST 95% COVERAGE OF DISTURBED
AREAS. RESEEDING WILL BE REQUIRED AS NECESSARY BY
THE CONTRACTOR TO OBTAIN THE SPECIFIED STAND OF GRASS.
NOTE:
THE ANGLE FOR GRADED SLOPES AND FILL SHALL BE NO GREATER
THAN THE ANGLE THAT CAN BE RETAINED BY VEGETATIVE COVER
OTHER ADEQUATE EROSION CONTROL DEVICES OR STRUCTURES. IN
ANY EVENT, SLOPES LEFT EXPOSED WILL, WITHIN 21 CALENDAR DAYS
OF COMPLETION OF ANY PHASE OF GRADING, BE PLANTED OR
OTHERWISE PROVIDED WITH TEMPORARY OR PERMANENT GROUND
COVER, DEVICES, OR STRUCTURES SUFFICIENT TO RESTRAIN EROSION.
