Sec. 58-47.- Building permit applications. (a) New residence. No building permit shall be issued for any new building that will be connected to an ISTS until a site evaluation and design is approved by the on-site systems manager. The site evaluation must include the identification of both primary and alternate drainfield sites suitable for a minimum of a five-bedroom residence. If the building will be connected to an existing system, a site evaluation and design must be approved by the city, including the existing system specifications and a future site meeting the provisions of this article. A new residence must be connected to an ISTS meeting the definition of a code system. (b) Required upgrade or replacement. A sewage treatment system not meeting the requirements of Minnesota Rules Chapter 7080, as amended, or the requirements of this article, whichever is more restrictive, must be upgraded, at a minimum, at any time a building permit is required for any improvements on, or use of, the property, subject to the following: (1) Any such system for which the city has previously issued orders requiring upgrade or replacement of the system by December 31, 2007, shall not be subject to this requirement until January 1, 2008. (2) Any such system forwhich the city has previously issued orders requiring upgrade or replacement of the system by December 31, 2010, shall not be subject to this requirement until January 1, 2011. (3) Regardless whether previous upgrade or replacement orders have been issued, this upgrade or replacement requirement shall not apply when said building permit is for regular maintenance or upkeep including but not limited to replacement of mechanical equipment such as air conditioning, furnaces, water heaters, or water softeners, or for re-roofing, re-siding or window replacement. (c) Construction of additional bedrooms or construction including water-using appliances that will increase the sewage flow into an /STS. A building permit shall not be issued until the city confirms that the existing ISTS is compliant and of adequate size to treat the sewage flow from the building and that a future drainfield site is designed and preserved. If the existing ISTS must be repaired or replaced, an ISTS design for both the existing ISTS and a future drainfield site must be approved before issuing a building permit. If expansion or replacement of the ISTS is required, the ISTS must be installed and inspected before a certificate of occupancy shall be issued for the construction. Failure to identify satisfactory drainfield sites for the proposed sewage flow for use now as well as a future site shall result in the denial of the building permit application. (d) Expansion of an existing building, including decks and patios; construction of an accessory building, driveway or land alteration. A future drainfield site must be designed and preserved prior to the issuance of a building permit for any expansion of an existing building, construction to an accessory building or driveway or land alteration on a property using an ISTS. A building permit will not be issued when the proposed work would preclude the use of the only future drainfield site approved by the city. (Code 1984, § 12.30(4)(F); Ord.
