A temporary modification to a failed onsite wastewater treatment system may be performed without obtaining a permit in accordance with these regulations if the modification is to prevent a surface discharge or reduce a threat to public health. The temporary modification must be registered with a written description submitted with the registration which states that a temporary modification was made and which also specifically describes the problem that caused the discharge with the reason the temporary modification was made. A system with a temporary modification is not to be operated for more than four months without Department approval.
