In South Carolina, industrial facilities and construction sites must have a stormwater pollution prevention plan (SWPPP). A SWPPP is a written document that outlines the measures and practices that will be implemented to prevent stormwater pollution. It is a must-have requirement for businesses operating in South Carolina because it helps protect our precious water resources from harmful pollutants.

Without a properly drafted SWPPP, industrial facilities and construction sites may face fines and penalties for non-compliance with state regulations. A comprehensive SWPPP ensures your business stays compliant and environmentally responsible.

With the expertise of Pro SWPPP, you can easily draft and implement your SWPPP. This allows you to focus on your business operations while being mindful of environmental regulations. 

So, let’s dive into some important details about SWPPP requirements in South Carolina!

Obtain an NPDES Permit

Any construction activity disturbing one or more acres must secure a National Pollutant Discharge Elimination System (NPDES) permit from the South Carolina Department of Health and Environmental Control (SCDHEC). This permit is crucial for regulating stormwater discharge. It helps manage and reduce the impact of pollutants entering water systems during construction. Without this permit, construction sites face legal actions and potential fines.

To obtain an NPDES permit, submit a Notice of Intent (NOI) to the SCDHEC. This includes details about your construction project, such as its location, type of work, and measures to control stormwater runoff.

After reviewing your NOI, the SCDHEC will determine if your plan meets state regulations. Once approved, you must follow the guidelines in your SWPPP to maintain compliance and protect water quality throughout the construction process.

Site-Specific Planning

Customizing your SWPPP to the unique conditions of your site is essential for effective stormwater management. This customization can lead to better protection against soil erosion and pollutant runoff.

Here are a few details to consider when customizing your SWPPP:

  • Soil Type: Different soils absorb water at various rates. Understanding your site’s soil type allows you to plan appropriate runoff control measures.
  • Slope of the Land: Steeper slopes require more robust erosion control practices. Plan accordingly to prevent soil displacement and water runoff.
  • Vegetation Cover: Existing plants can help control erosion and absorb runoff. Assess the vegetation on-site to leverage natural erosion control.
  • Specific Pollutants: Identify the primary pollutants at your site and implement targeted measures to address them. For example, machinery may need specific containment solutions for oil and grease.

Tailoring your SWPPP helps ensure it effectively manages stormwater in line with your site’s unique environmental conditions. This approach promotes compliance with state regulations while protecting local water quality.

Erosion and Sediment Controls

Implementing best management practices (BMPs) for controlling erosion and sediment is crucial to meeting the SWPPP requirements in South Carolina. These techniques prevent soil displacement and pollutant runoff from construction sites, helping to protect water quality.

Some common BMPs include silt fences, sediment basins, and soil stabilization methods. Silt fences are a barrier to trapping sediments before they enter water systems. Sediment basins collect runoff and allow sediments to settle before discharge. Soil stabilization involves using materials or techniques to keep soil in place during construction activities.

It is important to customize these BMPs based on the specific climate and terrain of your site in South Carolina. This ensures that they are effective in managing stormwater and preventing pollution.

Pollutant Source Management

Identifying and outlining procedures for managing potential pollutant sources are critical parts of a SWPPP. Construction materials like wood and concrete, chemicals like paints and solvents, and byproducts like sawdust and concrete washout must be stored and handled properly to prevent stormwater contamination.

Construction Material Management

Regularly inspect material storage areas to ensure they remain secure and dry. Use tarps or other coverings to protect materials from precipitation and runoff.

Chemical Handling and Storage

Seal and label all chemical containers. Store them in a covered area with a secondary containment system to catch any spills or leaks.

Byproducts and Waste Management

Collect byproducts like sawdust and concrete washout immediately after they are produced. Dispose of them in designated facilities, not in waterways or storm drains.

Training and Supervision

Educate your construction team on proper storage, handling, and disposal procedures. Regular supervision ensures that these practices are followed consistently to prevent stormwater contamination.

Maintain Detailed Records

Keep comprehensive records of all inspections, maintenance activities, and updates to your SWPPP. This is important because it helps you stay organized and ensures you’re following state regulations. Write down any time you inspect your site or make changes to your SWPPP.

This documentation should include details like the date of the inspection, what was checked, and any problems found. Make sure this information is easy to find and ready for the South Carolina Department of Health and Environmental Control (SCDHEC) to review when needed.

Detailed records also make it easier to show that your site complies with the SWPPP requirements. If there are ever questions or concerns about your stormwater management practices, you can easily prove that you have maintained your site correctly.

Control Construction Entrances

One effective way to prevent sediment from leaving your site is by implementing measures at construction entrances. This helps maintain the integrity of public roadways and prevents polluted runoff from entering local water systems.

Some measures you can take at construction entrances include using stabilized entrance pads or wash stations. A stabilized entrance pad is a reinforced gravel area that trucks and vehicles must drive through before exiting the site, removing excess soil and debris from their tires.

Wash stations use water hoses to clean off any remaining debris on vehicles before they leave the site, helping to prevent sediment tracking onto public roads.
