Notice of Intended Action

Proposing rule making related to NPDES general permit no. 6

and providing an opportunity for public comment

The Environmental Protection 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.198.

State or Federal Law Implemented

This rule making implements, in whole or in part, Iowa Code sections 455B.173(11), 455B.186 and 455B.198.

Purpose and Summary

The purpose of this proposed rule making is to renew National Pollutant Discharge Elimination System (NPDES) General Permit No. 6 (GP6), which authorizes the discharge of wastewater associated with well construction activities. The permit requires the implementation of best management practices and requires visual monitoring of the wastewater effluent to determine compliance with the state's water quality standards.

The rule making includes changes to GP6 in order to increase clarity and to comply with existing state rules. The renewed permit will include an authorization to discharge treated wastewater from drilling fluid and drilling mud if the discharge complies with Iowa's narrative water quality criteria in subrule 61.3(2). Well drillers have recently improved their capability to treat the liquid portion of drilling fluid and drilling mud to the point that it will meet narrative water quality criteria. The renewed permit will also include a new limitation on coverage for discharges to outstanding Iowa waters (OIWs) so that GP6 complies with Iowa's antidegradation rules in subparagraph 64.7(2)"f"(5). The antidegradation rules require individual NPDES permits for discharges to OIWs.

A copy of the proposed permit is available online at www.iowadnr.gov/Environmental-Protection/Water-Quality/NPDES-Wastewater-Permitting/NPDES-General-Permits/GP6-Water-Wells.

This rule making has no fiscal impact to the State of Iowa. A copy of the fiscal impact statement is available from the Department of Natural Resources upon request.

Jobs Impact
