SC Digital Stormwater Permits: Property Manager's Guide

Quick answer: South Carolina stopped accepting paper applications for construction stormwater permits on May 5, 2025. Every NPDES construction permit now goes through the SCDES ePermitting portal. Before you can submit anything, each person filing has to complete a Certifier Agreement with a wet signature and pass identity verification. Fees are paid through the portal instead of by check, and local MS4 programs have had to rework how they coordinate with the state. The rule covers any project that disturbs one acre or more, from Charleston to Beaufort to Bluffton to Hilton Head.

South Carolina’s shift to digital-only stormwater permitting isn’t a tech upgrade. It’s a change in how property managers, HOA boards, and facility operators handle construction projects. If you manage commercial properties, oversee HOA infrastructure work, or coordinate facility improvements that disturb soil, your permitting workflow changed completely.

The transition affects any project that disturbs one acre or more of land, or that’s part of a larger common plan of development, and requires an NPDES construction stormwater permit. That includes parking lot expansions, building additions, utility installations, pond dredging projects, and major landscaping work. Miss the digital requirements and your project timeline stops cold.

Here’s what property managers need to understand about the ePermitting system and how to work through it without delays.

What Changed on May 5, 2025

SCDES opened a grace period on April 7, 2025, accepting both digital and paper submissions. That grace period ended May 5. Now all NPDES construction stormwater permit applications go through the ePermitting portal. No exceptions. Mail in a paper Notice of Intent after that date and it won’t be reviewed. It won’t come back with a note asking you to resubmit online. It simply isn’t processed.

Every construction stormwater permit type is now digital-only:

• Notices of Intent (NOIs) for general construction permits
• Individual Lot NOIs for single-lot residential construction
• Transfers of Ownership when a permitted site changes hands
• Major Modifications to existing permits
• Notices of Termination (NOTs) when construction is complete and the site is stabilized

The change also applies to redevelopment work, renovation projects, and infrastructure improvements, not just ground-up construction.

For property managers handling multiple sites across the Lowcountry, this means digital workflows for stormwater compliance in Charleston, Beaufort, Bluffton, Hilton Head, and throughout South Carolina’s coastal counties. We covered the original announcement when the mandate first landed in SCDES Switches to Mandatory ePermitting for Construction Stormwater.

Why CROMERR Drove the Change

This wasn’t a state initiative. The move came out of federal CROMERR requirements, the EPA’s Cross-Media Electronic Reporting Rule, which governs how environmental reports and permit applications can be submitted electronically. States had a December 2025 deadline to comply.

South Carolina rolled it out in phases, starting with industrial stormwater programs before moving to construction permits. Other southeastern states are working through similar timelines, so property managers who operate across state lines should expect the same shift in Georgia, North Carolina, and Florida.

CROMERR is also why the registration process is heavier than a typical online account. The rule requires the state to verify that the person hitting submit really is who they claim to be, and that they have legal authority to certify the information. That’s the whole reason the Certifier Agreement exists.

The Certifier Agreement Requirement

Here’s the part that catches people off guard. Before you can submit any permit application, every person filing must complete a Certifier Agreement. This isn’t creating a login. It’s a formal registration that includes identity verification and acknowledgment of legal responsibility.

The Certifier Agreement process requires:

• A completed agreement form with an original wet signature, actual ink on paper
• Identity verification through the SCDES authentication process
• Confirmation of authority to submit permits on behalf of your organization
• Acknowledgment that submitted information is accurate and complete
• Understanding of the penalties for false statements
• Agreement to electronic signature protocols

You can’t share accounts. You can’t delegate submissions to non-certified staff. Each property manager or company representative who needs to file has to go through certification individually, and each authorized signatory needs their own certifier status.

The wet signature requirement is the bottleneck in an otherwise digital process. Physical paperwork has to travel by mail, and verification takes several business days on top of that. Property managers have waited weeks for authorized user status while construction schedules kept moving. Start this before you need it.

If your organization uses outside consultants or engineering firms for permit applications, confirm they’ve completed their Certifier Agreements too. Don’t assume. Ask. Plenty of property managers discovered this requirement only when trying to submit a time-sensitive filing.

How the ePermitting Workflow Actually Works

Once your certifier status is active, the process runs like this:

1. Account setup. Complete the Certifier Agreement with wet signature and mail it to SCDES.
2. Digital access. Receive login credentials and authorized user status.
3. Application preparation. Gather required documents in digital format: site plans, drainage calculations, SWPPP documents, property details.
4. Online submission. Complete the application through the ePermitting portal and pay the fee.
5. Status tracking. Monitor progress and receive correspondence electronically.

SCDES set up dedicated support for the transition. The Permitting Customer Service Line is 1-800-274-9965 and email support is permithelp@des.sc.gov. Both handle questions about account creation, submission problems, and permit status.

Payment Processing and Fee Changes

You can no longer write a check to a local municipality for your state permit fee, and you can’t mail a check to SCDES. All construction stormwater permit fees are processed through the portal using:

• Credit cards, which carry processing fees
• Electronic fund transfers from business bank accounts
• ACH payments for larger fees

Credit card processing fees are worth watching on larger projects. Electronic bank transfers usually cost less.

Fee amounts are set by SCDES and published on their current fee schedule, and they vary by permit type. Check the schedule before you budget a project rather than working from an old number, since the amounts and the categories have both moved over the past few years.

The system generates electronic receipts. Keep them. Some local jurisdictions want proof of NPDES fee payment before they’ll approve their own permits, so immediate access to payment confirmation affects project scheduling.

For property management companies handling several projects, electronic payment means tighter coordination of payment authorization and record keeping. Project managers writing checks out of petty cash isn’t an option anymore.

Local MS4 Coordination Got Harder

The digital-only requirement created real friction between SCDES and local MS4 programs. A lot of municipalities used the SCDES paper NOI form as part of their own erosion control permitting. With the paper form gone, local programs had to rework their procedures on short notice.

Some municipalities now ask applicants for a printout from the ePermitting system after they’ve submitted to SCDES. Others built their own paper applications for the local requirement while requiring separate digital submission to SCDES for the NPDES piece.

North Augusta is a good example of the fee side of this. The city now requires NPDES permit fees to be paid through SCDES ePermitting rather than by check to local authorities, which breaks the old habit of bundling state and local fees into one local submission.

The practical workflow now looks like this:

1. Submit and pay for the NPDES permit through SCDES ePermitting
2. Obtain payment confirmation from the state system
3. Provide proof of payment to the local jurisdiction for their permits
4. Track state and local approval timelines separately

Requirements vary by municipality, so check with each jurisdiction where you work. What worked in 2024 for coordinating state and local permits may not work the same way now. If your property sits inside an MS4 boundary, the local program’s own permit changes are worth tracking too. Our SC MS4 permit changes guide covers what’s shifting on that side.

Ongoing Projects, Modifications, and Renewals

The digital mandate doesn’t only affect new projects. Property managers overseeing existing developments often need permit modifications, renewals, or amendments for later construction phases.

All permit modifications now go through ePermitting, even for projects that started under the paper system. That means establishing digital access and certifier status for partially complete projects too.

For HOA communities with ongoing amenity construction, infrastructure improvements, or stormwater system upgrades, this adds a step to project management. HOA boards need to work with their property managers to confirm digital compliance capability is in place before a permit need shows up.

Common Implementation Problems

Property managers across South Carolina have hit the same handful of issues.

Certifier Agreement delays top the list, for the reasons above. The fix is starting early, not working faster.

Document quality issues cause rejections. SCDES requires clear, legible PDFs for supporting documentation. Poor scan quality, oversized files, or documents that miss the format requirements get kicked back. Establish a scanning protocol that consistently produces acceptable files, and check the portal’s file size and format limits before you assemble a submission.

System navigation slows down experienced teams. The interface works nothing like a paper form. Steps that were straightforward on paper take several screens online. SCDES publishes training materials and user guides, but hands-on familiarity takes time.

Authorization management matters more at larger organizations. You need clear internal rules for who can submit, who can access permit information, and who corresponds with SCDES for which property or client. The system logs all user activity, which makes authorization both more important and more visible.

Multi-property structures complicate the Certifier Agreement itself. Companies managing developments under different corporate entities or ownership structures may need separate agreements for each.

Enforcement Tracking Moved Into the Same System

This is the part that gets underplayed. The ePermitting platform handles formal and informal enforcement actions, penalties, and fines, not just applications. Violations, inspections, and compliance actions are recorded in the same system used for permitting.

That creates a complete digital record that follows properties and responsible parties across multiple projects. The upside is earlier warning. Instead of waiting for a formal violation notice in the mail, you can monitor inspection results and compliance status in the portal. The downside is that your compliance history is now permanently legible to the agency and easy to pull up during any future review. If you want to understand where that path leads when it’s ignored, read what happens when you ignore a stormwater violation notice.

Training and Support Resources

SCDES publishes training material for the ePermitting system, but you need to spend time on the platform before a deadline is bearing down.

Available resources include online tutorials for the application process, webinars covering common scenarios, technical support for navigation issues, and FAQ documents specific to construction stormwater permits.

The two problems that come up most often are document formatting and electronic signature protocols. On paper you could attach any relevant document. Digital submissions have specific format and size requirements, and every required party has to sign electronically before you can submit.

A practical tip: run a practice application on a small project before you tackle a large, time-sensitive one. The learning curve is manageable. It’s just easier to climb when nothing is on fire.

Getting Your Team Ready

Identify and certify key personnel

Decide who in your organization will handle permit submissions and get them through the Certifier Agreement process now. Don’t wait for a project deadline to start.

Update project timelines

Digital submissions aren’t automatically faster. Review times still depend on how complete your application is and what the agency’s workload looks like. Build in extra preparation time while your team is learning, and expect coordination with local permits to take longer while municipalities finish adapting.

Coordinate with local jurisdictions

Contact the municipalities where you work regularly and confirm what they now require for NPDES coordination. Proof-of-payment rules and timing requirements differ from city to city.

Establish digital file management

Track submissions, confirmation numbers, and approval documentation. The paper trail is entirely digital now, so your filing system should match. Keep local copies of approved permits for field reference and backup copies of everything you submit, including payment confirmations, in case you have to resolve a processing problem.

Update client communication

Property owners, developers, and contractors all need to know paper applications are gone. It affects project planning, document preparation, and submission timelines on their side too.

Plan for multi-project management

If you oversee several developments at once, build a workflow for tracking permit status across all of them inside the portal.

What You Get Out of It

The transition costs you training time and process changes up front. It does pay back for property managers handling multiple sites or ongoing stormwater management responsibilities.

Digital records give you complete permit history accessible from anywhere, automated reminders for renewals and compliance deadlines, integration with inspection scheduling and reporting, and better coordination between state permits and local requirements.

For HOA boards managing stormwater infrastructure, digital permits create clearer documentation of maintenance obligations. Board members can pull current permit information without depending on paper files that may be incomplete or out of date.

None of that changes what you already owe on the maintenance side. Inspection and maintenance requirements are unaffected by how you file. HOAs and commercial property managers still face fines for failing to maintain their systems, regardless of how clean the permit paperwork looks.

Worth remembering that the agency itself is relatively new. SCDHEC split into SCDES and DPH on July 1, 2024, and the ePermitting mandate arrived less than a year later. If you’re still updating templates and contact lists from that change, our post on what the SCDHEC to SCDES transition changed covers the administrative cleanup.

As South Carolina municipalities keep moving their own processes online, the ePermitting system will likely tie into local permit systems, which would cut a step out of projects that need both.
