Such redirected connections must be approved by the agency responsible for administering and operating those systems. c. The department may require any underground or above ground pipe, drain or other conduit, that has not been documented in plans, maps or equivalent, and which may be connected to the city's separate storm sewer system, to be located by the owner or occupant of that property upon receipt of written notice from the department.

Results of these investigations are to be documented and provided to the department. Failure to comply with the terms of the written notice mentioned within this sub- section shall constitute a violation of this Code Division.
