Georgia Erosion and Sedimentation Control for Construction

Erosion and sedimentation control is a legally mandated framework that governs how construction sites in Georgia manage soil disturbance, stormwater runoff, and sediment discharge. The Georgia Erosion and Sedimentation Act of 1975 (O.C.G.A. § 12-7-1 et seq.) establishes the baseline requirements, which are administered by the Georgia Environmental Protection Division (EPD) and enforced through a network of certified local governments. Any construction activity that disturbs land has the potential to carry sediment into waterways, causing ecological damage and regulatory liability — making compliance a foundational obligation on virtually every Georgia job site.

Definition and scope

The Georgia Erosion and Sedimentation Act defines erosion as the detachment and transport of soil particles by water, wind, ice, or gravity, and sedimentation as the deposition of those particles in water bodies, drainage channels, or adjacent land. The Act's scope covers any land-disturbing activity in Georgia — grading, clearing, dredging, filling, or excavating — that alters natural terrain.

The primary regulatory program is the Land Disturbing Activity (LDA) permit, issued under the authority of Georgia EPD or a certified local issuing authority (LIA). A certified LIA is a county or municipality that has received Georgia EPD approval to administer the program independently within its jurisdiction. As of the program's structure under O.C.G.A. § 12-7-8, any person or entity conducting a LDA on one or more acres must obtain a permit before ground disturbance begins.

Scope boundary: This page addresses Georgia state law under O.C.G.A. § 12-7-1 et seq. and Georgia EPD regulations. Federal requirements under the Clean Water Act's NPDES Construction General Permit — administered nationally by the U.S. Environmental Protection Agency and delegated to Georgia EPD — operate in parallel and are not fully addressed here. Construction activities on federally owned land or involving federal wetland permits (Section 404, U.S. Army Corps of Engineers) fall outside the scope of Georgia's state LDA program. Municipalities with their own supplemental stormwater ordinances may impose requirements beyond state minimums; those local overlays are also not covered on this page.

How it works

Georgia's erosion and sedimentation control framework operates through a structured, multi-step process:

1. Pre-application planning. The project owner or contractor prepares an Erosion, Sedimentation, and Pollution Control Plan (ESPC Plan) that identifies all proposed best management practices (BMPs) — physical controls such as silt fences, sediment basins, rock check dams, and construction exits — matched to site-specific conditions including slope, soil type, drainage patterns, and proximity to streams.

2. Plan review and LDA permit issuance. The ESPC Plan is submitted to the applicable certified LIA or, where no LIA exists, directly to Georgia EPD. The reviewing body evaluates compliance with the Manual for Erosion and Sediment Control in Georgia (commonly called the Green Book), which is published by the Georgia Soil and Water Conservation Commission (GASWCC) and sets technical standards for BMP design and placement.

3. Permit issuance and fee payment. Georgia EPD sets a permit fee schedule tied to disturbed acreage. Permit fees are assessed per the fee schedule authorized under O.C.G.A. § 12-7-12.2. Sites must also obtain coverage under Georgia's NPDES Construction General Permit (CGP) for disturbances of 1 acre or more, which requires submission of a Notice of Intent (NOI) to Georgia EPD.

4. Implementation of BMPs. Once permitted, the contractor installs and maintains all BMPs shown in the approved ESPC Plan before and during land disturbance. BMPs must be inspected by a Certified Erosion, Sedimentation, and Pollution Control Inspector (CESCPI) — a credential administered by GASWCC — at minimum every 14 calendar days and within 24 hours of a 0.5-inch or greater rainfall event.

5. Corrective action and recordkeeping. Inspection findings must be documented. Any BMP deficiency must be corrected within 7 days (or as soon as practicable in the case of adverse weather). Inspection records are subject to regulatory review and must be retained for 3 years after project completion.

6. Notice of Termination (NOT). Once final stabilization is achieved — defined as rates that vary by region uniform vegetative cover or an equivalent permanent stabilization measure on all disturbed areas — the permittee submits a NOT to Georgia EPD to close CGP coverage.

Site operators are also required to implement good housekeeping controls to prevent construction materials, concrete washout, fuels, and other pollutants from entering stormwater conveyances. This intersects directly with Georgia construction safety regulations and broader Georgia building permit process compliance requirements.

Common scenarios

Residential subdivision development. A 50-lot subdivision disturbing 30 acres requires both an LDA permit from the certified county LIA and NPDES CGP coverage. The developer installs a sediment basin sized to handle runoff from the full disturbed area before any grading begins. Each phase of grading must be stabilized before the next phase opens.

Commercial site development. A 4-acre retail pad site in a metropolitan county triggers the LDA permit, NPDES CGP, and any local post-construction stormwater management requirements. The contractor must designate a CESCPI who conducts and documents all required inspections throughout construction.

Linear infrastructure projects. Road and utility projects disturbing land in linear corridors — pipelines, transmission lines, roadway expansions — must address erosion control sequentially across multiple drainage basins. The Georgia Department of Transportation maintains its own erosion control standards for GDOT projects, addressed separately at Georgia Department of Transportation Construction.

Single-lot single-family residential. Disturbances under 1 acre on a single-family residential lot may be exempt from LDA permit requirements under O.C.G.A. § 12-7-17(3), though local ordinances may impose independent requirements. This exemption does not apply if the disturbed area is part of a larger common plan of development.

Decision boundaries

The critical classification distinction in Georgia's erosion control program is the 1-acre threshold:

• Less than 1 acre disturbed (standalone): Generally exempt from state LDA permit and NPDES CGP requirements, subject to the "common plan of development" exception. Local ordinances may still apply.
• 1 acre or more disturbed: LDA permit required; NPDES CGP coverage required; CESCPI inspections required; ESPC Plan required and must be approved before disturbance begins.

A second critical boundary involves certified vs. non-certified local authority jurisdiction. In counties and municipalities with a certified LIA, the LIA is the issuing authority and primary inspector. In jurisdictions without a certified LIA — approximately rates that vary by region of Georgia's land area falls into this category structurally — Georgia EPD assumes direct permitting and inspection responsibility.

The contrast between temporary BMPs and permanent stormwater controls is also decision-relevant. Silt fences, sediment traps, and rock check dams are temporary controls required only during active construction. Permanent controls — detention ponds, bioretention areas, infiltration systems — are governed by separate post-construction stormwater rules and may be subject to local utility authority requirements. The distinction determines which regulatory program governs design review, inspection, and long-term maintenance obligations. For post-construction stormwater requirements, see Georgia Stormwater Management for Construction.

Violations of the Georgia Erosion and Sedimentation Act carry civil penalties of up to amounts that vary by jurisdiction per day per violation (O.C.G.A. § 12-7-12), with stop-work order authority available to both Georgia EPD and certified LIAs. Criminal penalties apply for willful or knowing violations. Understanding these boundaries is essential for any contractor operating under a Georgia general contractor license on projects with significant ground disturbance.
