The following discharges are exempt from the prohibition provision above:

(2) Discharges or flows from fire fighting, and other discharges specified in writing by the City of Urbana as being necessary to protect public health and safety;
(3) The prohibition provision above shall not apply to any non-stormwater discharge permitted under an NPDES permit or order issued to the discharger and administered under the authority of the State and the Federal Environmental Protection Agency, provided that the discharger is in full compliance with all requirements of the permit, waiver, or order and other applicable laws and regulations, and provided that written approval has been granted for any discharge to the municipal separate storm sewer system.
(b) Prohibition of Illegal Connections. The construction, connection, use, maintenance or continued existence of any illegal connection to the municipal separate storm sewer system is prohibited.
(1) This prohibition expressly includes, without limitation, illegal connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection.
(2) A person violates this chapter if the person connects a line conveying sewage to the municipal separate storm sewer system, or allows such a connection to continue.
(3) Improper connections in violation of this chapter must be disconnected and redirected to an approved onsite wastewater management system or the sanitary sewer system upon approval of the City of Urbana Sanitary Sewer Superintendent.
(4) Any drain or conveyance that has not been documented in plans, maps or equivalent, and which may be connected to the storm sewer system, shall be located by the owner or occupant of that property upon receipt of written notice of violation from the City of Urbana requiring that such locating be completed. Such notice will specify a reasonable time period within which the location of the drain or conveyance is to be completed, that the drain or conveyance be identified as storm sewer, sanitary sewer or other, and that the outfall location or point of connection to the storm sewer system, sanitary sewer system or other discharge point be identified. Results of these investigations are to be documented and provided to the City of Urbana. (Ord. 4383. Passed 3-13-12.)
