Remediation
VerifiedNWP 38: Cleanup of Hazardous and Toxic Waste
Specific activities required to affect the containment, stabilization, or removal of hazardous or toxic waste materials that are performed, ordered, or sponsored by a government agency with established legal or regulatory authority. Court ordered remedial action plans or related settlements are also authorized by this NWP.
Acreage limit
The 2026 rule states no acreage limit for NWP 38. Eligibility turns on the activity description in the rule text and the general conditions that apply, not on a numeric cap.
Pre-construction notification: Always required
Every use of NWP 38 requires a pre-construction notification to the district engineer before work begins. There is no minimum-impact threshold that exempts a project from this requirement.
If a PCN is required, general condition 32 gives the district engineer 30 calendar days to determine whether it is complete, then up to 45 calendar days from receipt of the complete PCN to respond before the permittee may proceed. Those are two separate clocks, not one.
