Notice of Intended Action

Proposing rule making related to NPDES general permit no.5

and providing an opportunity for public comment

The Environmental Protection Commission (Commission) hereby proposes to amend Chapter 64, "Wastewater Construction and Operation Permits," Iowa Administrative Code.

Legal Authority for Rule Making

This rule making is proposed under the authority provided in Iowa Code section 455B.173(11).

State or Federal Law Implemented

This rule making implements, in whole or in part, Iowa Code sections 455B.173(11) and 455B.186.

Purpose and Summary

The purpose of this proposed rule making is to renew National Pollutant Discharge Elimination System (NPDES) General Permit No.5 (GP5), which authorizes the discharge of wastewater associated with mining and processing facilities. The permit requires the implementation of best management practices and requires monitoring of the wastewater effluent to determine compliance with applicable limits.

The rule making includes changes to GP5 in order to increase clarity, add definitions, revise the definition for "Water of the United States" to reference the federal definition as of June 22, 2020 (effective date of the final Navigable Waters Protection Rule published by the United States Environmental Protection Agency), and comply with existing state rules. Annual fees are required with GP5. Fees are specified in Iowa Code section 455B.197 and are not impacted by this rule making.

A copy of the proposed permit is available online at www.iowadnr.gov/Environmental-Protection/Water-Quality/NPDES-Wastewater-Permitting/NPDES-General-Permits/ GP5-Mining-Processing.
