Federal vs. State
EPA CGP vs. State CGP Training Requirements
EPA issues the Construction General Permit directly in only a handful of jurisdictions. Almost every other state runs its own EPA-authorized NPDES construction stormwater program, and can add training requirements the federal baseline doesn't include.
Two Permitting Paths, One Federal Law
Every construction stormwater permit in the U.S. traces back to the Clean Water Act's NPDES program. But who actually issues and enforces the Construction General Permit (CGP) on a given project depends on where that project is. EPA directly issues the CGP in a small number of jurisdictions. Everywhere else, an EPA-authorized state program issues its own version, and states are free to add requirements the federal permit doesn't include.
EPA is the direct CGP permitting authority in Massachusetts, New Hampshire, New Mexico, DC, and most U.S. territories and tribal lands. Roughly 47 states run their own EPA-authorized NPDES construction stormwater programs.
Side by Side
How Each Path Works
EPA-Issued CGP (Direct Federal)
In Massachusetts, New Hampshire, New Mexico, DC, and most territories and tribal lands, EPA is the direct permitting authority. Site inspections must be performed by a "qualified person," a standard EPA does not itself certify individuals against. EPA offers a free Construction Inspection Training Course as a resource. See the Construction General Permit (CGP) overview.
State-Issued CGP (EPA-Authorized State Program)
About 47 states are authorized under the Clean Water Act to run their own NPDES construction stormwater permit programs. These state permits use the same federal legal foundation but can layer on additional or different requirements, state-specific training, formal inspector credentials (like Washington/Oregon's CESCL), California's QSP/QSD system, or state-specific sampling and reporting rules. See State Stormwater Permit Requirements for state-by-state detail.
Comparison
EPA-Issued CGP vs. State-Issued CGP
| Aspect | EPA-Issued CGP (Direct Federal) | State-Issued CGP (Authorized State Program) |
|---|---|---|
| Where it applies | Massachusetts, New Hampshire, New Mexico, DC, most territories/tribal lands | The other ~47 states, using their own NPDES-authorized permit |
| Inspection standard | "Qualified person", EPA does not certify individuals | Varies by state, some mirror EPA's language, others add formal credentials |
| Example added requirement | None beyond CGP baseline | California: QSP/QSD (CASQA); Washington/Oregon: CESCL inspector credential |
| Training availability | Free EPA Construction Inspection Training Course | State-specific courses, often fee-based and state-administered |
| Legal basis | Clean Water Act Section 402 / 40 CFR 122.26 (NPDES) | Same federal basis, delegated to the state under EPA authorization |
Before You Enroll
Confirm Which Permit Governs Your Project
The practical takeaway: don't assume the federal CGP baseline is all you need. If your project is in one of the ~47 states running its own authorized program, check that state's specific training, credential, and reporting requirements before relying on general stormwater training alone. See Stormwater Regulations & Standards for the broader regulatory picture and State Stormwater Permit Requirements for state-specific detail.
