ARC 3310C
ENVIRONMENTAL PROTECTION COMMISSION[567]
Notice of Intended Action
Twenty-five interested persons, a governmental subdivision, an agency or association of 25 or more persons may demand an oral presentation hereon as provided in Iowa Code section 17A.4(1)“b.”
Notice is also given to the public that the Administrative Rules Review Committee may, on its own motion or on written request by any individual or group, review this proposed action under section 17A.8(6) at a regular or special meeting where the public or interested persons may be heard.
Pursuant to the authority of Iowa Code section 455B.173(11), the Environmental Protection Commission hereby gives Notice of Intended Action to amend Chapter 64, “Wastewater Construction and Operation Permits,” Iowa Administrative Code.
The purpose of this proposed amendment is to reissue the existing National Pollutant Discharge Elimination System (NPDES) Private Sewage Disposal Systems General Permit known as General Permit No.	4 (GP4). This permit authorizes discharges from private sewage disposal systems such as sand filters, other media filters, and aerobic treatment units that will reach a designated water of the state or a subsurface drainage tile. These types of systems are used where soil absorption is not possible due to soil or geological conditions or the presence of a high groundwater table. The permit will be renewed for five years, and the only changes being made to the permit are updates to the effective dates. There are no fees associated with GP4.
Any interested person may file written comments on the proposed amendment on or before October 18, 2017. Written comments or questions regarding the proposed amendment should be directed to Daniel A. Olson, Iowa Department of Natural Resources, 502 East 9th Street, Des Moines, Iowa 50309-0034; via fax at (515)725-8202; or via e-mail at daniel.olson@dnr.iowa.gov.
A copy of the proposed GP4 is available online at www.iowadnr.gov/Environmental-Protection/Water-Quality/Private-Septic-Systems/General-Permit-4.
A public hearing where persons may present their views orally or in writing will be held on October 3, 2017, from 2:30 to 4:30 p.m.	at the Wallace State Office Building, 502 East 9th Street, Des Moines, Iowa, in the fifth floor conference room 5E. At the hearing, persons will be asked to give their names and addresses for the record and to confine their remarks to the subject of the amendment.
Any persons who intend to attend a public hearing and have special requirements, such as hearing or mobility impairments, should contact the Department to advise of any specific needs.
After analysis and review of this rule making, it has been determined that there will be no impact on private sector jobs and employment opportunities in Iowa. GP4 has been in existence since 1998 (and in its current form since 2012) and has been accepted by the private sewage industry and rural homeowners as necessary to allow the discharge of treated private sewage disposal system effluent to a designated water of the state or to a subsurface drainage tile.
This amendment is intended to implement Iowa Code sections 455B.183(1)“c” and 455B.173(11).
The following amendment is proposed.
	Amend subrule 64.15(4) as follows:
	64.15(4) “Discharge from Private Sewage Disposal Systems,” NPDES General Permit No. 	4, effective March 18, 2009 February 1, 2018, to March 17, 2011 January 31, 2023.
