A temporary modification to a failed onsite wastewater treatment system may be performed without meeting the design requirements of Title 124 - Rules and Regulations for the Design, Operation, and Maintenance of Onsite Wastewater Treatment Systems if the modification is to prevent a surface discharge or reduce a threat to public health.
The temporary modification must be registered. A written description must accompany the registration which:
Use of a system with a temporary modification for more than four months without Department approval is prohibited.
- States that a temporary modification was made; and
- Describes the problem that caused the discharge and the reason the temporary modification was made.
Only a certified professional, a professional engineer, a registered environmental health specialist, or a person under their direct supervision, may engage in the inspection, pumping, siting, layout, construction, reconstruction, alteration, modification, repair, closure or otherwise changing of an onsite wastewater treatment system. “Direct supervision” means the person overseeing the work is physically present on the site where the work is being done and has control over, responsibility for, and professional knowledge of the work being done.
