1.0 Introduction

Federal law (Clean Water Act) allows EPA to govern storm water discharges from construction sites. This is typically addressed by preparation and implementation of a Storm water Pollution

Prevention Plan (SWPPP) and filing with South Carolina Department of Environmental Services

(SCDES) a Notice of Intent (NOI) for storm water discharges from construction activities. This is to request that the project be covered under South Carolina’s NPDES General Permit for

Stormwater Discharges from Construction Activities, SCR100000 (CGP). (NPDES is National

Pollutant Discharge Elimination System). NPDES permit coverage is required in Clarendon

County for projects with soil disturbances of 1 acre or more.

Development, implementation, and maintenance of the SWPPP provides the framework for reducing soil erosion and minimizing pollutants in storm water during construction of this project.

The SWPPP will:

Define the characteristics of the site and the type of construction which will be occurring;

Describe the practices that will be implemented to control erosion and the release of pollutants in storm water;

Create an implementation schedule to ensure that the practices described in this

SWPPP are in fact implemented and to evaluate the plan’s effectiveness in reducing erosion, sediment, and pollutant levels in storm water discharged from the site;

Describe the final stabilization/termination design to minimize erosion and prevent storm water impacts after construction is complete.

This SWPPP includes the following:

Identification of the SWPPP Owner /Operator with a description of duties;

Identification of the storm water pollution prevention team that will assist in implementation of the SWPPP during construction.

Description of the existing site conditions including existing land use for the project area (i.e., wooded areas, open grassed areas, pavement, buildings, etc.), and soil types at the site, The location of any surface waters which have been identified on or next to the site

(wetlands, streams, rivers, lakes, ponds, etc.);

Identification of the body of water(s) which will receive runoff from the construction site, including the major body of water that receives the storm water;

Identification of drainage areas and potential storm water contaminants;

Description of storm water management controls and various Best Management

Practices (BMPs) necessary to reduce erosion, sediment and pollutants in storm water discharge;

Description of the project monitoring plan and how controls will be coordinated with construction activities;

Description of the implementation schedule and provisions for amendment of the plan.

The following sections presents the above listed information in detail. Provided separately are the Construction Drawings that present the detailed site design and stormwater management and pollution prevention features described herein.

3.0 PROJECT NARRATIVE

The Clarendon County Water and Sewer Department owns and operates a water system south of

Manning that includes approximately 93 miles of water main in sizes from 2” to 12” diameter. The system originally included six separate small water systems. Projects including Phases 1, 1A, 1B, 1C, and 2 have combined with the six separate systems and expanded these into two main systems. The larger of which is SCDHEC System Number 1450010 (which Phase 5 will be included). The other system is SCDHEC System Number 1450003 which serves Wyboo Point and Eagle Pointe Subdivisions.

The Phase 5 project includes construction of approximately 13 miles of 8”, 6” and 3” water mains.

The disturbed area along the 13 miles is estimated as about 9.5 acres total. Work will be spread over about a 9 month time period with only about 0.1 acre disturbed during a single day before stabilization measures being implemented. Site soils in the Project area are Primarily Fuquay B

(FuB), Dothan A (DoA) and Rains (Ra). Other soils in the local area are shown on Soils Map, Figure 3.

The USDA Soil Conservation Service Soil Survey of Clarendon County indicates the following soil characteristics:

Fuquay soils consist of nearly level to sloping deep, well drained soils. Typically the surface layer is dark grayish-brown fine sand about 7 inches thick. The subsurface layer is pale-brown fine sand about 20” thick. The next 27-39 inches are sandy loam. Permeability is moderate in the upper part of the subsoil and slow in the lower part. Runoff is slow. Depth to seasonal high water table is greater than 6 feet. Available water capacity is low to medium. The content of organic matter is low.

The Dothan soils (DoA, DoB) are loamy fine sand, sandy clay loam, or sandy loam, depending upon depth. The first 0-16 inches are loamy fine sand and the next 16-70 inches are sandy clay loam and sandy loam. Dothan soils are fair as topsoil, have fair traffic supporting capacity, and are well drained. The depth to the seasonal high water table is greater than 6 feet.

The Rains soils (Ra) are sandy loam or sandy clay loam, depending upon depth. The first 0-7 inches are sandy loam and the next 7-72 inches are sandy clay loam and sandy loam. Rains soils are poor as topsoil, have poor traffic supporting capacity, and have a high water table. The depth to the seasonal high water table is 0-1 foot.

5.0 STORMWATER MANAGEMENT

The purpose of this section is to identify the types of temporary and permanent erosion and sediment controls that will be used during construction activities. The controls will provide soil stabilization for disturbed areas and structural controls to divert runoff and remove sediment. This section will also address control of other potential storm water pollutant sources such as construction materials (paints, concrete dust, solvents, plaster), waste disposal, control of vehicle traffic, and sanitary waste disposal.

The construction plans furnished separately as Appendix D contains the following drawings:

Sheet L1 – Site Plan and Profile: This sheet provides the Water Main layout and general notes.

Sheets P-1 through P-31 provide water main plans with erosion controls.

Sheet EC-1 – Erosion Control Plan: This sheet provides detailed information on proposed erosion and sediment control Best Management Practices (BMP’s), Notes, etc..

Sheet EC-2 – Erosion Control Details: This sheet provides additional details for

BMP’s and earthwork and paving specifications.

Control Measures

To prevent soil from washing into the highway swales or into undisturbed areas of the site, the following BMP’s will be implemented:

Silt fencing will be placed along the lower perimeter of the area to be cleared and graded as shown on Appendix D Sheet 2. This silt fence should be placed prior to any land disturbing activity. Two rows of silt fence will be provided where work is within 50’ of wetland areas. (No wetlands are within 50’)

A stabilized construction entrance will be constructed off of end of existing paving as shown on Appendix D, EC-2.

Sediment tubes will be installed in drainage swales as shown on Appendix D, sheets

EC-1 and EC-2. Provide others where needed on site as work progresses.

Temporary and permanent grassing will be applied as specified on Appendix D sheet

EC-1.

Any areas or stock piles will be seeded with temporary or permanent seeding no later than 14 days following the last construction activity in that area.

The temporary perimeter controls (silt fencing, etc.) will not be removed until all construction activities at the site are complete and soils have been stabilized.

Areas of the site to be paved will be temporarily stabilized with crushed stone base until asphalt is applied.

Construction Practices to Minimize Storm Water Contamination

Practices to minimize storm water contamination during construction and to address applicable non-numeric effluent limits identified in Section 3.2.10 of the CGP include:

Limiting the amount of disturbed area and exposed soils. Do not stockpile excavated material where sediment can erode into surface waters.

Leave native shoreline vegetation, (especially woody vegetation) unaltered wherever possible.

Staging and/or phasing of the construction sequence (see construction plans sheet 4).

Provide BMP sediment basins or traps for concentrated flow.

Divert off-site stormwater flow around the construction area.

Provide securely lidded dumpster for disposal of all trash and construction debris during building operations. When dumpster is not available, contractor is responsible to collect and package debris daily and transport to appropriate licensed landfill. Dumpsters should be emptied at least twice per month or when full and trash or debris hauled by licensed haulers to appropriate landfill.

All personnel working at the site are to be instructed in the correct procedure for waste disposal, housekeeping and spill prevention practices.

Portable sanitary facilities shall be provided on site for construction personnel. All sanitary waste is to be disposed of by a licensed sanitary waste management contractor. Empty at least weekly or as recommended by the waste management contractor for the number of personnel on site.

Fertilizers and other site chemicals or to be used in the minimum amounts recommended by the manufacturer and stored in covered areas or sealed bins, etc. to avoid spills.

All vehicles and construction equipment on site will be monitored for leaks and receive regular preventive maintenance to reduce the chance of leakage. Do not store in or near wetland areas.

All vehicle maintenance will occur in designated areas with appropriate spill prevention and containment measures implemented.

Provide materials and equipment necessary for spill cleanup on site during construction.

Equipment to include brooms, dust pans, mops, rags, gloves, goggles, spill absorbents, plastic and metal trash containers and other equipment specific to the work ongoing.

Spray guns or chemical application equipment to be cleaned on removable tarps or plastic sheet.

Concrete trucks will not be allowed to washout or discharge surplus concrete or drum wash water on the site. Prevent wet concrete from contacting surface waters.

All spills should be cleaned up immediately upon discovery. Spills large enough to reach the storm water system will be reported to the SCDES State ERS at 1-888-481-0125 and the local SCDES office 803-778-6548. Contractors performing various types of work will be responsible for providing specific spill prevention control and countermeasure plans for their type of work or material usage.

Dump trucks hauling materials to or from the site will be covered with a tarpaulin.

Other measures may be necessary and should be included in this plan when identified by the

Owner / Operator / Contractor.

6.0 Maintenance

6.1 Inspections

Visual inspections of all disturbed and graded areas of the construction work will be performed daily while work is ongoing and all sediment and erosion control devices shall be inspected at least every seven (7) days. The inspection will be conducted by the SWPPP coordinator or his designated storm water team members. The inspection will verify that the structural BMPs described in Section 5 of this SWPPP are in good condition and are minimizing erosion. The inspection will also verify that the procedures used to prevent storm water contamination from construction materials and petroleum products are effective. If site inspections identify BMP’s that are damaged or not operating effectively, maintenance must be performed as soon as practical or as reasonably possible and before the next storm event whenever practicable.

The following inspection and maintenance practices will be used to maintain erosion and sediment controls:

Built up sediment will be removed from silt fencing when it has reached one-third the height of the fence.

Silt fences will be inspected for depth of sediment, for tears, to see if the fabric is securely attached to the fence posts, and to see that the fence posts are firmly in the ground.

Any sediment basins or traps (none planned at this time) will be inspected for depth of sediment and built up sediment will be removed when it reaches 1 foot in depth.

Temporary and permanent seeding will be inspected for bare spots, washouts, and healthy growth.

The work will be inspected for sediment tracked on the road (clean as required), and to make sure that the culverts are clear and working.

The maintenance inspection report will be made after each inspection. A copy of the report form to be completed by the SWPPP coordinator is provided in Appendix B of this SWPPP. Completed forms will be maintained at Clarendon County Administration Building, County Engineers Office during the entire construction project. Following construction, the completed forms will be retained at the same location for a minimum of 1 year.

If construction activities or design modifications are made to the project plans which could impact storm water, this SWPPP will be amended appropriately. The amended SWPPP will have a description of the new activities that may contribute to the increased pollutant loading and the planned source control activities.

6.2 Employee Training

A training program will be developed and implemented to educate employees about the requirements of the SWPPP. This education program will include background on the components and goals of the SWPPP emphasizing erosion controls, spill prevention and response, good housekeeping, proper material handling, disposal and control of waste, equipment fueling, and proper storage, washing, and inspection procedures. All employees will be trained prior to their first day on the site.

6.3 Certification

Certification statements are provided in Appendix C and in the “Notice of Intent for Storm Water

Discharge” which will be submitted with this SWPPP to SCDES.
