Any onsite wastewater treatment system constructed, reconstructed, altered, modified, or otherwise changed by a certified professional, professional engineer, or registered environmental health specialist must be registered with the Department by the certified professional, professional engineer, or registered environmental health specialist within 45 days of completion of the construction, reconstruction, alteration, modification, or other change. The Department has interpreted completion of work to mean that all onsite wastewater treatment system components have been installed, constructed or modified so that the system piping, treatment devices or other appurtenances that convey, treat or dispose of wastewater are ready to be used. The NDEQ does not consider construction completion of an onsite system to be dependent upon construction of any dwelling or building to which the system may be connected, final grading, seeding, or the date of receipt of payment for work performed.

Registration is not required for inspecting, pumping, or performing a repair to a system. Title 124 - Rules and Regulations for the Design, Operation, and Maintenance of Onsite Wastewater Treatment Systems defines repair as Repair means the correction of a mechanical, electrical, or minor structural defect in an existing onsite wastewater system component such as, but not limited to, sealing a crack in a tank lid, repairing or replacing a tank baffle or access manhole riser, repairing or replacing a pump or electrical switch, leveling a distribution box, replacing a building sewer pipe, or replacing a cracked pipe between the septic tank and soil absorption system. Repair does not include replacement, reconstruction or modification of a tank or soil absorption system; extension or enlargement of a soil absorption component and system; replacement of a distribution pipe; or repair or replacement of a metal or concrete block tank.

To register an onsite wastewater treatment system, the certified professional, professional engineer, or registered environmental health specialist must submit the required system information with the non-refundable registration fee of $140. An initial late registration fee is required for any registration received by the Department 46 to 90 days after completion of the system and is in addition to the system registration fee. A final late registration fee is required for any registration received by the Department 91 or more days after completion of the system and is in addition to the system registration fee.
