Georgia Erosion and Sedimentation Act: Permits, Buffers, Penalties

Georgia’s Erosion and Sedimentation Act (O.C.G.A. Title 12, Chapter 7) requires most construction projects disturbing one acre or more of land to obtain a land-disturbing activity permit, follow a certified erosion control plan, and protect vegetative buffers along state waters before any ground is broken. Violations carry stop-work orders and civil penalties up to $2,500 per day, each day counted as a separate offense.¹

When the Act Applies to Your Project

The trigger is soil disturbance. Clearing, grading, excavating, filling, and hauling soil all count as land-disturbing activity if they may cause erosion or move sediment into state waters or onto other property. “State waters” is defined broadly to include rivers, streams, creeks, lakes, ponds, drainage systems, springs, and wells that are not entirely confined to one property.²

The threshold that pulls a project into the Act is one acre of disturbance. Below that, most projects are exempt. Two situations pull small projects back under the rules.

Common Plans of Development

If you subdivide a parcel into half-acre lots and sell them to different builders, each lot on its own is under the acre threshold. The Act looks at the whole plan. Plat maps, zoning applications, sales advertisements, or boundary stakes are all documentation that ties lots together into a common plan.³ Once the combined planned disturbance reaches an acre, every lot in the plan needs permit coverage.

The 200-Foot Rule

A project under one acre also loses its exemption if the work sits within 200 feet of state waters. For this rule only, “state waters” excludes channels that carry water only during and immediately after rainstorms and intermittent streams that don’t flow year-round. Even so, if your under-one-acre project sits near one of those excluded channels, you still have to keep sediment from leaving your property.⁴

Who Is Exempt

O.C.G.A. § 12-7-17 lists several activities that are outside the Act’s reach:⁴

Agriculture — plowing, planting, cultivation, pasture establishment, farm structures, and livestock or poultry management.
Forestry — timber harvesting and forest management. Note the catch: if forestry work disturbs a vegetative buffer along state waters, no other land-disturbing activities are allowed on that property for three years after the forestry work ends.
Minor residential work — home gardens, personal landscaping, fence installation, and routine maintenance producing only minor erosion.
Single-family home construction disturbing less than an acre, provided the lot isn’t part of a larger plan exceeding an acre. Trout stream buffer rules still apply.
Any project under one acre, unless it’s part of a larger common plan or is within 200 feet of state waters.
Surface mining and granite quarrying, which are regulated under separate Georgia statutes.

Buffers Along State Waters

Vegetative buffers are the Act’s first defense against sediment reaching waterways. Required widths depend on the water body:

Standard state waters: a 25-foot undisturbed buffer, measured horizontally from the point where normal stream flow or wave action has worn away vegetation on the bank.⁵
Trout streams: a 50-foot buffer. Small first-order trout streams (fed only by springs, no tributaries) flowing 25 gallons per minute or less may qualify for a reduced 25-foot buffer or be piped at the landowner’s discretion under a general variance rule.⁵
Coastal marshlands: a 25-foot buffer, measured from the marshland-upland interface.⁵

No land-disturbing activity, heavy equipment operation, or permanent structure placement is allowed inside these buffers. Trout waters get stricter treatment: for primary trout waters, no variance to a smaller buffer is available. For secondary trout waters, the director may grant a variance down to 25 feet, but no less.⁵

Who on the Project Must Be Certified

Georgia requires anyone involved in land development, design, plan review, permitting, construction, monitoring, inspection, or any land-disturbing activity to hold Georgia Soil and Water Conservation Commission (GASWCC) certification.⁶ Working without the right certification can jeopardize your permit. There are three levels:

Level IA (Fundamentals) — the baseline for builders, contractors, developers, site superintendents, grading and utility contractors, and monitoring consultants.
Level IB (Advanced Fundamentals) — for regulatory and non-regulatory inspectors evaluating site compliance.
Level II (Introduction to Design) — for the professionals who design erosion control plans and the reviewers who evaluate them. A Level II design professional’s signature and seal must appear on every sheet of the plan.⁷

The Erosion Control Plan

The Erosion, Sedimentation, and Pollution Control Plan (ES&PC Plan) is the core of any application. A Level II certified design professional must prepare and seal it, and must certify a site visit before designing it.⁷

The plan must show how the project will use best management practices (BMPs) to keep sediment on site. Common structural controls include silt fences, sediment basins, fiber rolls, storm drain inlet protections, and construction entrance track-out controls.⁸ It must also address stabilization, showing where and when permanent vegetation or other permanent ground cover will be established as grading finishes in each area.

Submitting a plan without the design professional’s Level II certification number, site visit certification statement, and proper seal on each sheet will get the plan returned without review.⁷ The GASWCC’s plan review checklist lays out every element reviewers look for.

Two Permits, Not One

Most Georgia construction projects need two separate permits, and this catches applicants off guard. The state land-disturbing activity permit issued under the Erosion and Sedimentation Act is one. The federal NPDES stormwater permit, issued by Georgia’s Environmental Protection Division, is the other.

EPD issues NPDES general permits for construction stormwater discharges (including GAR100002 for infrastructure projects) covering sites that will disturb one or more contiguous acres, or smaller sites that are part of a larger common plan reaching an acre.⁹ The current infrastructure permit runs through July 31, 2028.

To get NPDES coverage, you must submit a Notice of Intent (NOI) to EPD electronically at least 14 days before starting construction, with a copy to your Local Issuing Authority if one exists. A Stormwater Pollution Prevention Plan (SWPPP) must be developed to meet the permit’s conditions.⁹ The SWPPP overlaps heavily with the ES&PC Plan required under state law, but they are technically distinct documents.

One warning worth reading twice: even if your Local Issuing Authority approves your erosion control plan, that approval is not a defense against NPDES violations. The NPDES permit explicitly states that local government approval does not shield you from federal stormwater enforcement.⁹

Where to File and How Long It Takes

Where you file depends on whether your project sits inside a Local Issuing Authority (LIA) jurisdiction. Many Georgia cities and counties have been certified as LIAs and handle land-disturbing activity permits locally. If your project is in an LIA jurisdiction, you submit the ES&PC Plan and permit application to the LIA, which forwards the plan to the local Soil and Water Conservation District for technical review.¹⁰

The District has 35 days to approve or deny the plan. Denials require revisions, and each resubmission triggers another 35-day review. If your plan passes on first review, the full process to permit issuance should take no more than 45 days.¹⁰ Most delays come from plan deficiencies, not slow review.

If no LIA covers your area, you file directly with the appropriate Georgia EPD District Office. No separate land-disturbing activity permit is required in that scenario; you submit the ES&PC Plan with your NOI to EPD.¹⁰

Fees

State permit fees are capped at $80 per disturbed acre. Many LIAs charge their own administrative fees on top, and those local surcharges vary widely, so ask your LIA early for the full cost. Some jurisdictions also require a financial assurance bond before issuing the permit, typically calculated per disturbed acre, to cover stabilization if the project is abandoned or falls out of compliance. The bond is released when final stabilization is approved.

Closing Out the Permit

Getting the permit is only half the job. You must file a Notice of Termination (NOT) once all soil-disturbing activities have ended and the site has reached final stabilization. Final stabilization means all unpaved areas not covered by permanent structures are uniformly covered in permanent vegetation with at least 70 percent density, or covered by equivalent permanent stabilization measures. Planned landscaped areas must be uniformly covered in landscaping materials per the approved plan. A crop of annual vegetation does not count.¹¹

For common development projects, the primary permittee can only file a NOT when all construction has ceased for at least 90 days, every secondary permittee has achieved final stabilization and filed their own NOT, all temporary BMPs have been removed, and the site is in full compliance.¹¹

Failing to close out the permit is one of the most common compliance failures. Permit obligations continue until the NOT is accepted, which means ongoing inspection duties, BMP maintenance, and exposure to penalties for the entire time the permit remains open.

Penalties

State and local officials can issue stop-work orders on the spot when they find a site out of compliance. A stop-work order halts all activity until the violation is corrected.¹

Civil penalties reach $2,500 per day for any person who violates the Act, its regulations, or any permit condition, and each day counts as a separate offense. A two-week violation adds up to $35,000 in fines before remediation costs. Municipal and magistrate courts hearing cases under local ordinances adopted under the Act carry the same $2,500-per-violation authority.¹

The financial exposure runs beyond the fines. A project sitting idle under a stop-work order keeps accruing loan interest, equipment rental, and crew standby pay. Getting the ES&PC Plan properly designed, keeping BMPs maintained through construction, and closing out with documented final stabilization is the cheapest path through this process by a wide margin.
