National Federation of Independent Business comment letter of September 21, 2026, in response to EPA notice of proposed rulemaking titled "Updates to the National Pollutant Discharge Elimination System Definitions and Exclusions," Docket No. EPA-HQ-OW-2026-6965, 91 Fed. Reg. 56819 (September 4, 2026), is attached.

Abstract

The proposal would revise the regulatory definition of “discharge of a pollutant” to align with the Clean Water Act’s (CWA) definition of “discharge of a pollutant” or “discharge.” The regulatory definition would be updated to reflect the statutory exclusion of vessels and other floating craft that add pollutants in the contiguous zone or the ocean from NPDES program requirements. The proposed rule would also make conforming and clarifying changes to the NPDES regulatory exclusion for vessels and other floating craft. The result of the proposed rule, if finalized, would be that the addition of pollutants by a vessel or other floating craft in the contiguous zone or the ocean that is not secured to the seabed would not be a discharge and would not require NPDES permit authorization.
