MAINTENANCE PLAN

320-C Midland Parkway Summerville, SC 29485

SWPPP NARRATIVE:

The project site is located at Joint Base Charleston, entering the Naval Weapons Station in Goose Creek, South Carolina. The entry control facility area is along Perimeter Road, North of

Remount Road. The site consists of an existing vehicle processing area, to remain, with a new active vehicle barrier, overwatch structure, and associated supporting infrastructure.

Total area site disturbance is slightly under one acre. According to the USDA Soil Survey, the soils found at the site consist of Bonneau loamy sand as well as borrow pit material. Bonneau loamy sand conforms within hydrologic soil group “B” (moderately well drained), and borrow pit soils are assumed to be hydrologic soil group “D” (poorly drained).

The nearest receiving water body (RWB) for storm water discharge is Filbin Creek, which ultimately reaches the Cooper River. The Filbin Creek tributary is approximately 3878’ South of the project site. Storm water is then conveyed approximately 6000’ downstream to the Cooper

River, a coastal receiving Water (CRW) which is classified as Freshwater (FW) per SCDHEC.

Best Management Practices for Sediment and Erosion Control are in place for this project to protect existing conditions, and the construction will not contribute to any impairments. To limit the sediment discharge from the site, temporary silt fence will be installed along the edges of earthwork, demolition, and construction disturbance. A construction staging area, enclosed with silt fence with gravel construction entrances, shall prevent construction vehicle tracking.

Once construction has been completed, all disturbed areas shall be sodded or seeded with grass in accordance with the plans, specifications, and following direction. Upon stabilization of grassed area, sediment control measures shall be removed and all sediment and debris must be removed from the area of work.

The proposed site disturbance requires consideration of the Energy Independence and

Security Act of 2007 (EISA) provision requirements to the greatest extent technically feasible.

The attached NOI package for Automatic Coverage should be completed/signed by the prime contractor (serving as "project Owner/Operator”) & submitted to JB CHS MS4 Office (JB

CHS 628 CES/CEIE; C Wannamaker. For additional information, refer to the design drawings, Erosion & Sedimentation Control Practices and Maintenance Plans within this package.

PLANNED EROSION AND SEDIMENTATION CONTROL PRACTICES

1. SEDIMENT (SILT) FENCE –

Silt fence will be provided along specified edges of the project site as shown in the drawings. The silt fence will limit the amount of eroded material leaving the site until a vegetative cover is established.

2. TEMPORARY GRAVEL CONSTRUCTION ENTRANCE/EXITS –

Gravel entrance pads, as detailed, will be installed as shown on the plans to provide a buffer to cut down on material leaving the construction staging area where vehicles leave the work area. The contractor will be responsible for cleaning and adding stone if an excessive amount of mud or debris accumulates.

3. LAND GRADING

The grading plan has been developed with consideration of what areas need to be graded, when the work will start and stop, the degree and length of finished slopes, where borrow will be needed and where excess material will be wasted. The contractor will coordinate grading operations while utilizing the erosion and sedimentation control measures set forth in the plans.

4. CONCRETE TRUCK WASHOUT

Temporary concrete washout facilities should be located a minimum of 50 feet from storm drain inlets, open drainage facilities, and watercourses, unless determined infeasible by the

Engineer. Each facility should be located away from construction traffic or access areas to prevent disturbance or tracking. Install a sign adjacent to each washout facility to inform concrete equipment operators to utilize the proper facilities.

MAINTENANCE PLAN

SCDHEC Standard Notes:

1. 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 fourteen (14) days after work has ceased, except as stated below.

• Where stabilization by the 14th day is precluded by snow cover or frozen ground conditions stabilization measures must be initiated as soon as practicable.

• 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.

2. 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, the permittee must address the necessary replacement or modification required to correct the bmp within 48 hours of identification.

3. 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. Do not pump the filtered water into waters of the state.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.

9. Minimize soil compaction and, unless infeasible, preserve topsoil.

10. 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;

11. 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.).

12. The following discharges from sites are prohibited:

• Wastewater from washout of concrete, unless managed by an appropriate control;

• Wastewater from washout and cleanout of stucco, paint, form release oils, curing

• Compounds and other construction materials;

• Fuels, oils, or other pollutants used in vehicle and equipment operation and maintenance;

• Soaps or solvents used in vehicle and equipment washing.

13. 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.

14. 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.

15. A pre-construction conference must be held for each construction site with an approved on-site SWPPP prior to the implementation of construction activities.

320-C Midland Parkway

Additional Erosion Control Maintenance Notes:

1. Install permanent vegetative cover and the long-term erosion protection measures or structures as soon as practical in the development process.

2. Provide for handling the increased runoff caused by changed soil and surface conditions. Use effective means to conserve existing on-site soil including the use of diversion ditches, grassed waterways and storm sewers.

3. Place silt fence barriers at locations shown on plan. Silt barriers shall be maintained in place and in good condition until ground cover is established.

4. All disturbed areas not paved shall be grassed. Use temporary plant cover, mulching, and/or structures to control runoff and protect areas subject to erosion during construction.

5. Contractor shall provide dumpster of sufficient size and number to contain the solid waste generated by the project.

6. Contractor shall frequently remove garbage to maintain a clean construction site and minimize the exposure of waste to storm water.

SCDHEC STANDARD NOTES:

ENVIRONMENTAL REQUIREMENTS FOR JOINT BASE CHARLESTON:

1. GROUNDWATER MONITORING WELLS

SEVERAL MONITORING WELLS ARE LOCATED NEAR OR WITHIN THE PROPOSED PROJECT AREA AT JOINT BASE

CHARLESTON WEAPONS (JBCHS WEAPONS). EVERY EFFORT SHOULD BE MADE TO PROTECT THE INTEGRITY OF THESE

MONITORING WELLS, AS THEY ARE CURRENTLY BEING USED TO MONITOR THE EFFECTIVENESS OF REMEDIATION

EFFORTS. SEE SITE MAPS PROVIDED FOR WELL LOCATIONS.

ANY WELLS DAMAGED OR DESTROYED DURING THE PROJECT MUST BE REPAIRED OR REPLACED. COORDINATION FOR

PROPER ABANDONMENT AND RE-INSTALLATION SHOULD BE WITH THE RESTORATION PROGRAM MANAGER (RPM), MR.

HAYES PATTERSON AT 843-963-2708 (HAYES.PATTERSON@US.AF.MIL) AND SOUTH CAROLINA DEPARTMENT OF HEALTH

AND ENVIRONMENTAL (SCDHEC) BUREAU OF LAND AND WASTE MANAGEMENT, EITHER THE DIVISION OF WASTE

MANAGEMENT, DEPARTMENT OF DEFENSE CORRECTIVE ACTION OR THE UNDERGROUND STORAGE TANK MANAGEMENT

DIVISION, CORRECTIVE ACTION SECTION, DEPENDING ON THE TYPE OF WELL. NOTE THAT SUCH COORDINATION IS NOT

WITH THE SCDHEC BUREAU OF WATER. WELL REPAIR, ABANDONMENT AND REPLACEMENT ARE THE RESPONSIBILITY OF

THE CONTRACTOR.

IF A WELL IS ABANDONED AND RE-INSTALLED A REGISTERED LAND SURVEYOR MUST SURVEY THE GROUND SURFACE, TOP OF CASING, AND TOP OF CONCRETE WELL PAD, AND PROVIDE THIS INFORMATION TO THE JBCHS WEAPONS RPM.

VERTICAL ELEVATIONS NEED TO BE REFERENCED TO THE NORTH AMERICAN VERTICAL DATUM 1988 (NAVD 88), U.S.

SURVEY FEET AND HORIZONTAL LOCATIONS (NORTHINGS AND EASTINGS) SHOULD BE REFERENCED TO UNIVERSAL

TRANSVERSE MERCATOR COORDINATES ZONE 17 NORTH.

ADDITIONALLY, A SC-CERTIFIED WELL DRILLER MUST BE USED FOR ALL WELLS THAT ARE ABANDONED OR RE-INSTALLED, AND A SCDHEC FORM 1903 (WATER WELL RECORD FORM) MUST BE PREPARED BY THE WELL DRILLER AND SUBMITTED TO

THE PROPER SCDHEC SECTION ABOVE (I.E. NOT THE BUREAU OF WATER) AND A COPY TO THE JBCHS WEAPONS RPM. IF

NECESSARY, ANY RE-INSTALLED MONITORING WELL(S) MUST BE PROPERLY DEVELOPED BY PUMPING UNTIL

GROUNDWATER IS CLEAR OF VISIBLE SEDIMENTS AND FIELD PARAMETER MEASUREMENTS ARE STABILIZED (PH VARIES

TO WITHIN 0.1 STANDARD UNITS, SPECIFIC CONDUCTIVITY VARIES TO WITHIN 10%, AND TEMPERATURE IS CONSTANT FOR

AT LEAST THREE CONSECUTIVE MEASUREMENTS). ALL FIELD DOCUMENTATION, INCLUDING THE DEVELOPMENT LOGS

AND WATER WELL RECORD FORMS, MUST BE PROVIDED TO THE JBCHS WEAPONS RPM.

2. CONTAMINATED SOIL

SOIL AT THE PROPOSED SITE IS CONTAMINATED. THE QUANTITY OF SOIL TO BE REMOVED FROM THE SITE HAS YET TO BE

DETERMINED. ANY SOIL TO BE REMOVED FROM THE SITE SHOULD BE EXCAVATED, CONTAINED IN 55-GALLON DRUMS OR

PLASTIC-LINED ROLL-OFF BINS, COVERED, LABELED WITH HOLD PENDING ANALYSIS STICKERS, AND STORED ON BASE

UNTIL THE SOIL HAS BEEN SAMPLED AND CHARACTERIZED. A COMPOSITE SOIL SAMPLE SHOULD BE COLLECTED FROM

EVERY ROLL-OFF BIN (OR ONE COMPOSITE SAMPLE FROM EVERY FIVE 55-GALLON DRUMS) AND ANALYZED FOR VOCS BY

METHOD 8260B AND TCLP METALS. ONCE CHARACTERIZED, THE APPROPRIATE LABEL(S) SHOULD BE PLACED ON THE

STORAGE CONTAINERS. ANY SOIL EXCAVATED AT THE SITE SHOULD BE PROPERLY DISPOSED OFF-BASE AND MUST BE

COORDINATED THROUGH MR. TOMMY HARDIN AT 843-963-2727. AFTER THE DATA IS EVALUATED, THE WASTE HAS BEEN

CHARACTERIZED, AND A WASTE STREAM CHARACTERIZATION PROCESS DOCUMENT (WSCPD) FOR CONTRACTORS HAS

BEEN PREPARED, THE WSCPD FORM MUST BE SIGNED BY MR. HAYES PATTERSON AT 843-963-2708

(HAYES.PATTERSON@US.AF.MIL) AND ALL THE INFORMATION MUST BE PROVIDED TO MR. TOMMY HARDIN AT

843-963-2727), WELL IN ADVANCE OF SHIPMENT AND PRIOR TO DISPOSAL. MR. HARDIN OR MR. PATTERSON WILL PROVIDE

THE CONTRACTOR A WASTE STREAM CHARACTERIZATION PROCESS DOCUMENT FORM. MR. HARDIN MUST SIGN THE

WASTE MANIFEST PRIOR TO OFF-BASE TRANSPORTATION AND DISPOSAL. THE SAME DISPOSAL PROCEDURES AND

COORDINATION MUST BE ADHERED TO FOR CONTAMINATED GROUNDWATER AS FOR CONTAMINATED SOIL.

TEMPORARY GRAVEL CONSTRUCTION ENTRANCE/EXIT

CONSTRUCTION ENTRANCE - GENERAL NOTES

CONSTRUCTION ENTRANCE - INSPECTION & MAINTENANCE

1. STABILIZED CONSTRUCTION ENTRANCES SHOULD BE USED

AT ALL POINTS WHERE TRAFFIC WILL EGRESS/INGRESS A

CONSTRUCTION SITE ONTO A PUBLIC ROAD OR ANY

IMPERVIOUS SURFACES, SUCH AS PARKING LOTS.

2. INSTALL A NON-WOVEN GEOTEXTILE FABRIC PRIOR TO

PLACING ANY STONE.

3. INSTALL A CULVERT PIPE ACROSS THE ENTRANCE WHEN

NEEDED TO PROVIDE POSITIVE DRAINAGE.

4. THE ENTRANCE SHALL CONSIST OF 2-INCH TO 3-INCH D50

STONE PLACED AT A MINIMUM DEPTH OF 6-INCHES.

5. MINIMUM DIMENSIONS OF THE ENTRANCE SHALL BE

15-FEET WIDE BY 20-FEET LONG, AND MAY BE MODIFIED AS

NECESSARY TO ACCOMMODATE SITE CONSTRAINTS.

6. THE EDGES OF THE ENTRANCE SHALL BE TAPERED OUT

TOWARDS THE ROAD TO PREVENT TRACKING AT THE EDGE

OF THE ENTRANCE.

7. DIVERT ALL SURFACE RUNOFF AND DRAINAGE FROM THE

STONE PAD TO A SEDIMENT TRAP OR BASIN OR OTHER

SEDIMENT TRAPPING STRUCTURE.

8. LIMESTONE MAY NOT BE USED FOR THE STONE PAD.

1. THE KEY TO FUNCTIONAL CONSTRUCTION ENTRANCES IS WEEKLY

INSPECTIONS, ROUTINE MAINTENANCE, AND REGULAR SEDIMENT

REMOVAL.

2. REGULAR INSPECTIONS OF CONSTRUCTION ENTRANCES SHALL BE

CONDUCTED ONCE EVERY CALENDAR WEEK AND, AS RECOMMENDED,

WITHIN 24-HOURS AFTER EACH RAINFALL EVEN THAT PRODUCES

1/2-INCH OR MORE OF PRECIPITATION.

3. DURING REGULAR INSPECTIONS, CHECK FOR MUD AND SEDIMENT

BUILDUP AND PAD INTEGRITY. INSPECTION FREQUENCIES MAY NEED TO

BE MORE FREQUENT DURING LONG PERIODS OF WET WEATHER.

4. RESHAPE THE STONE PAD AS NECESSARY FOR DRAINAGE AND RUNOFF

CONTROL.

5. WASH OR REPLACE STONES AS NEEDED AND AS DIRECTED BY SITE

INSPECTOR. THE STONE IN THE ENTRANCE SHOULD BE WASHED OR

REPLACED WHENEVER THE ENTRANCE FAILS TO REDUCE THE AMOUNT

OF MUD BEING CARRIED OFF-SITE BY VEHICLES. FREQUENT WASHING

WILL EXTEND THE USEFUL LIFE OF STONE PAD.

6. IMMEDIATELY REMOVE MUD AND SEDIMENT TRACKED OR WASHED

ONTO ADJACENT IMPERVIOUS SURFACES BY BRUSHING OR SWEEPING.

FLUSHING SHOULD ONLY BE USED WHEN THE WATER CAN BE

DISCHARGED TO A SEDIMENT TRAP OR BASIN.

7. DURING MAINTENANCE ACTIVITIES, ANY BROKEN PAVEMENT SHOULD BE

REPAIRED IMMEDIATELY.

8. CONSTRUCTION ENTRANCES SHOULD BE REMOVED AFTER THE SITE

HAS REACHED FINAL STABILIZATION. PERMANENT VEGETATION SHOULD

REPLACE AREAS FROM WHICH CONSTRUCTION ENTRANCES HAVE BEEN

REMOVED, UNLESS AREA WILL BE CONVERTED TO AN IMPERVIOUS

SURFACE TO SERVE POST-CONSTRUCTION.
