DESIGNER CERTIFICATION

" I HAVE PLACED MY SIGNATURE AND SEAL ON THE DESIGN

DOCUMENTS SUBMITTED SIGNIFYING THAT I ACCEPT

RESPONSIBILITY FOR THE DESIGN OF THE SYSTEM. FURTHER, I

CERTIFY TO THE BEST OF MY KNOWLEDGE AND BELIEF THAT THE

DESIGN IS CONSISTENT WITH THE REQUIREMENTS OF TITLE 48,

CHAPTER 14 OF THE CODE OF LAWS OF SC, 1976 AS AMENDED,

PURSUANT TO REGULATION 72-300 ET SEQ. (IF APPLICABLE), AND IN

ACCORDANCE WITH THE TERMS AND CONDITIONS OF SCR100000."

CEPSCI / SWPPP INSPECTIONS

THE CONTRACTOR IS RESPONSIBLE FOR ALL CEPSCI

(SWPPP) INSPECTIONS AND MAINTENANCE OF ALL

EROSION CONTROL MEASURES, PER THE PERMIT

REQUIREMENTS, FOR THE FULL DURATION OF THE

PROJECT THROUGH APPROVAL OF THE NOTICE OF

TERMINATION AND PROJECT CLOSEOUT.

10/10/2025

1. DORCHESTER COUNTY SHALL NOT MAINTAIN STORMWATER DETENTION OR RETENTION PONDS, OR DRAINAGE DITCHES AND SWALES. THE PROPERTY OWNER SHALL MAINTAIN ALL STORMWATER DETENTION FACILITIES SHOWN HEREON. THE OPERATING AND MAINTENANCE AGREEMENT WILL BE RECORDED WITH THE DORCHESTER COUNTY REGISTER OF DEEDS.

2. AN “AS-BUILT” PLAN CERTIFIED THAT THE FACILITIES HAVE BEEN CONSTRUCTED AS SHOWN AND THAT THE FACILITY MEETS THE APPROVED STORM WATER PLAN AND SPECIFICATION OR ACHIEVES THE FUNCTION FOR WHICH THEY WERE DESIGNED, SHALL BE SUBMITTED PRIOR TO: THE USE OR OCCUPANCY OF ANY COMMERCIAL OR INDUSTRIAL SITE, FINAL ACCEPTANCE OF ANY ROAD INTO THE OFFICIAL COUNTY ROAD INVENTORY, RELEASE OF ANY FINANCIAL GUARANTEES HELD BY THE COUNTY, AND/OR APPROVAL AND/OR ACCEPTANCE FOR RECORDING OF MAPS, PLATS, OR DRAWINGS, THE INTENT OF WHICH

IS TO CAUSE A DIVISION OF A SINGLE PARCEL OF LAND INTO TWO OR MORE PARCELS

3. A CERTIFIED STORMWATER AS-BUILT MUST BE SUBMITTED TO DCPW PRIOR TO LETTER OF OCCUPANCY, CLOSEOUT

PACKAGE, AND TO SCDES PRIOR TO RECEIVING A NOTICE OF TERMINATION.

4. IF NECESSARY, SLOPES, WHICH EXCEED EIGHT (8) VERTICAL FEET SHOULD BE STABILIZED WITH SYNTHETIC OR VEGETATIVE MATS, IN ADDITION TO HYDROSEEDING. IT MAY BE NECESSARY TO INSTALL TEMPORARY SLOPE DRAINS DURING

CONSTRUCTION. TEMPORARY BERMS MAY BE NEEDED UNTIL THE SLOPE IS BROUGHT TO GRADE.

5. STABILIZATION MEASURES SHALL BE INITIATED AS SOON AS PRACTICABLE IN PORTIONS OF THE SITE WHERE CONSTRUCTION ACTIVITIES HAVE TEMPORARILY OR PERMANENTLY CEASED, BUT IN NO CASE MORE THAN FOURTEEN (14) DAYS AFTER WORK

HAS CEASED, EXCEPT AS STATED BELOW:

A. WHERE STABILIZATION BY THE 14TH DAY IS PRECLUDED BY SNOW COVER OR FROZEN GROUND CONDITIONS

STABILIZATION MEASURES MUST BE INITIATED AS SOON AS PRACTICABLE.

B. WHERE CONSTRUCTION ACTIVITY ON A PORTION OF THE SITE IS TEMPORARILY CEASED, AND EARTH-DISTURBING ACTIVITIES WILL BE RESUMED WITHIN 14 DAYS, TEMPORARY STABILIZATION MEASURES DO NOT HAVE TO BE

INITIATED ON THAT PORTION OF THE SITE.

6. ALL SEDIMENT AND EROSION CONTROL DEVICES SHALL BE INSPECTED ONCE EVERY CALENDAR WEEK. IF PERIODIC INSPECTION OR OTHER INFORMATION INDICATES THAT A BMP HAS BEEN INAPPROPRIATELY OR INCORRECTLY INSTALLED, THE PERMITTEE MUST ADDRESS THE NECESSARY REPLACEMENT OR MODIFICATION REQUIRED TO CORRECT THE BMP

WITHIN 48 HOURS OF IDENTIFICATION.

7. PROVIDE SILT FENCE AND/OR OTHER CONTROL DEVICES, AS MAY BE REQUIRED, TO CONTROL SOIL EROSION DURING UTILITY CONSTRUCTION. ALL DISTURBED AREAS SHALL BE CLEANED, GRADED, AND STABILIZED WITH GRASSING IMMEDIATELY AFTER THE UTILITY INSTALLATION. FILL, COVER, AND TEMPORARY SEEDING AT THE END OF EACH DAY ARE RECOMMENDED.

IF WATER IS ENCOUNTERED WHILE TRENCHING, THE WATER SHOULD BE FILTERED TO REMOVE ANY SEDIMENTS BEFORE

BEING PUMPED BACK INTO ANY WATERS OF THE STATE.

8. ALL EROSION CONTROL DEVICES SHALL BE PROPERLY MAINTAINED DURING ALL PHASES OF CONSTRUCTION UNTIL THE COMPLETION OF ALL CONSTRUCTION ACTIVITIES AND ALL DISTURBED AREAS HAVE BEEN STABILIZED. ADDITIONAL CONTROL DEVICES MAY BE REQUIRED DURING CONSTRUCTION IN ORDER TO CONTROL EROSION AND/OR OFFSITE SEDIMENTATION.

ALL TEMPORARY CONTROL DEVICES SHALL BE REMOVED ONCE CONSTRUCTION IS COMPLETE AND THE SITE IS STABILIZED.

9. THE CONTRACTOR MUST TAKE NECESSARY ACTION TO MINIMIZE THE TRACKING OF MUD ONTO PAVED ROADWAY(S) FROM CONSTRUCTION AREAS AND THE GENERATION OF DUST. THE CONTRACTOR SHALL DAILY REMOVE MUD/SOIL FROM

PAVEMENT, AS MAY BE REQUIRED.

10. SWPPP SHOULD INCLUDE A CONCRETE WASHOUT STAGING AREA FOR SITE AND BUILDING CONSTRUCTION AND ALL OTHER

PURPOSES OF THE DEVELOPMENT TO INCLUDE BUT NOT BE LIMITED TO PAINTERS.

11. RESIDENTIAL SUBDIVISIONS REQUIRE EROSION CONTROL FEATURES FOR INFRASTRUCTURE AS WELL AS FOR INDIVIDUAL LOT CONSTRUCTION. INDIVIDUAL PROPERTY OWNERS SHALL FOLLOW THESE PLANS DURING CONSTRUCTION OR OBTAIN APPROVAL OF AN INDIVIDUAL PLAN IN ACCORDANCE WITH S.C. REG. 72-300 ET SEQ. AND SCR100000.

12. TEMPORARY DIVERSION BERMS AND/OR DITCHES WILL BE PROVIDED AS NEEDED DURING CONSTRUCTION TO PROTECT WORK AREAS FROM UPSLOPE RUNOFF AND/OR TO DIVERT SEDIMENT-LADEN WATER TO APPROPRIATE TRAPS OR STABLE

OUTLETS.

13. ALL WATERS OF THE STATE (WOS), INCLUDING WETLANDS, ARE TO BE FLAGGED OR OTHERWISE CLEARLY MARKED IN THE FIELD. A DOUBLE ROW OF SILT FENCE IS TO BE INSTALLED IN ALL AREAS WHERE A 50-FOOT BUFFER CAN'T BE MAINTAINED BETWEEN THE DISTURBED AREA AND ALL WOS. A 10-FOOT BUFFER SHOULD BE MAINTAINED BETWEEN THE LAST ROW OF

SILT FENCE AND ALL WOS.

14. LITTER, CONSTRUCTION DEBRIS, OILS, FUELS, AND BUILDING PRODUCTS WITH SIGNIFICANT POTENTIAL FOR IMPACT (SUCH AS STOCKPILES OF FRESHLY TREATED LUMBER) AND CONSTRUCTION CHEMICALS THAT COULD BE EXPOSED TO STORM WATER MUST BE PREVENTED FROM BECOMING A POLLUTANT SOURCE IN STORM WATER DISCHARGES.

15. A COPY OF THE SWPPP, INSPECTIONS RECORDS, AND RAINFALL DATA MUST BE RETAINED AT THE CONSTRUCTION SITE OR A NEARBY LOCATION EASILY ACCESSIBLE DURING NORMAL BUSINESS HOURS, FROM THE DATE OF COMMENCEMENT OF

CONSTRUCTION ACTIVITIES TO THE DATE THAT FINAL STABILIZATION IS REACHED.

16. INITIATE STABILIZATION MEASURES ON ANY EXPOSED STEEP SLOPE (3H:1V OR GREATER) WHERE LAND DISTURBING ACTIVITIES HAVE PERMANENTLY OR TEMPORARILY CEASED, AND WILL NOT RESUME FOR A PERIOD OF 7 CALENDAR DAYS.

17. MINIMIZE SOIL COMPACTION AND, UNLESS INFEASIBLE, PRESERVE TOPSOIL.

18. MINIMIZE THE DISCHARGE OF POLLUTANTS FROM EQUIPMENT AND VEHICLE WASHING, WHEEL WASH WATER, AND OTHER WASH WATERS. WASH WATERS MUST BE TREATED IN A SEDIMENT BASIN OR ALTERNATIVE CONTROL THAT PROVIDES

EQUIVALENT OR BETTER TREATMENT PRIOR TO DISCHARGE;

19. MINIMIZE THE DISCHARGE OF POLLUTANTS FROM DEWATERING OF TRENCHES AND EXCAVATED AREAS. THESE DISCHARGES

ARE TO BE ROUTED THROUGH APPROPRIATE BMPS (SEDIMENT BASIN, FILTER BAG, ETC.).

20. THE FOLLOWING DISCHARGES FROM SITES ARE PROHIBITED:

A. WASTEWATER FROM WASHOUT OF CONCRETE, UNLESS MANAGED BY AN APPROPRIATE CONTROL;

B. WASTEWATER FROM WASHOUT AND CLEANOUTS OF STUCCO, PAINT, FORM RELEASE OILS, CURING COMPOUNDS AND

OTHER CONSTRUCTION MATERIALS;

C. FUELS, OILS, OR OTHER POLLUTANTS USED IN VEHICLE AND EQUIPMENT OPERATION AND MAINTENANCE; AND

D. SOAPS OR SOLVENTS USED IN VEHICLE AND EQUIPMENT WASHING.

21. AFTER CONSTRUCTION ACTIVITIES BEGIN, INSPECTIONS MUST BE CONDUCTED AT A MINIMUM OF AT LEAST ONCE EVERY CALENDAR WEEK AND MUST BE CONDUCTED UNTIL FINAL STABILIZATION IS REACHED ON ALL AREAS OF THE CONSTRUCTION

SITE.

22. IF EXISTING BMPS NEED TO BE MODIFIED OR IF ADDITIONAL BMPS ARE NECESSARY TO COMPLY WITH THE REQUIREMENTS OF THIS PERMIT AND/OR SC'S WATER QUALITY STANDARDS, IMPLEMENTATION MUST BE COMPLETED BEFORE THE NEXT STORM EVENT WHENEVER PRACTICABLE. IF IMPLEMENTATION BEFORE THE NEXT STORM EVENT IS IMPRACTICABLE, THE SITUATION MUST BE DOCUMENTED IN THE SWPPP AND ALTERNATIVE BMPS MUST BE IMPLEMENTED AS SOON AS

REASONABLY POSSIBLE.

23. THE PROJECT/SITE MUST BE BUILT ACCORDING TO APPROVED COUNTY AND SCDES PLANS UNLESS SWPPP DOCUMENTS ARE UPDATED BY THE ORIGINAL SWPPP PREPARER, OTHERWISE PERMITS AND APPROVALS WILL BE INVALIDATED.

24. A PRE-CONSTRUCTION CONFERENCE MUST BE HELD FOR EACH CONSTRUCTION SITE WITH AN APPROVED ON-SITE SWPPP PRIOR TO THE IMPLEMENTATION OF CONSTRUCTION ACTIVITIES. FOR NON-LINEAR PROJECTS THAT DISTURB 10 ACRES OR MORE THIS CONFERENCE MUST BE HELD ON-SITE UNLESS THE DEPARTMENT HAS APPROVED OTHERWISE.
