Discharging Household Sewage Treatment Systems - General Permits

Draft Permit Renewal

This draft NPDES permit renewal replaces both existing permits, OHK000002 and OHL000002. Ohio Department of Health rules became effective recently that require local health districts to evaluate and participate in permitting of discharging household sewage treatment systems. These rules eliminate the need for Ohio EPA to review household sewage treatment system projects, the memorandum of understanding with local health districts, and the second NPDES permit for those local health districts that had not signed the memorandum.

The comment deadline is Nov. 25, 2016.


Ohio EPA has issued two general National Pollutant Discharge Elimination System (NPDES) permits for select new and replacement discharging household sewage treatment systems. Though effluent limitations, monitoring, record keeping and siting criteria for the two permits are identical, implementation or the determination of coverage under the applicable general NPDES permit is different.

General NPDES permit OHK000002 allows the local board of health where the household sewage treatment system is be located to determine eligibility or coverage under the permit. Under the conditions and criteria of general NPDES permit OHL000002, Ohio EPA will be responsible for making this determination.

In either case, coverage under the general NPDES permits cannot be granted if the residence can be served by an onsite soil absorption system or connected to sanitary sewers and only the local board of health can make this determination. Therefore, any residence or property owner should first contact the local board of health to determine the proper course of action.

Coverage under this general NPDES permit is determined by local boards of health that have signed Memorandums of Understanding (MOUs) with Ohio EPA. These MOUs allows the local board of health to determine permit coverage and provide for an expedited issuance process.

Under Ohio Revised Code 3718 (Amended Substitute House Bill No. 119), Ohio EPA was required to develop a general NPDES permit process that did not require the local board of health to enter into an MOU to determine coverage under a general NPDES permit. Under the provisions of this general NPDES permit, Ohio EPA will evaluate projects to determine eligibility after a Notice of Intent (NOI) is submitted for a project.
