Subsection 1003.1.1 is hereby added to the International Plumbing Code and shall read as follows:

1003.1.1 Grease interceptors required. If under the City of Olathe’s wastewater jurisdiction, new food service facilities that begin operation after February 15, 2010 must install an exterior, large-capacity grease interceptor that complies with the design requirements of Sections 1003.3.1 through 1003.3.5. Food service facilities in operation prior to February 15, 2010 shall be allowed to operate existing grease interceptors, provided they are maintained in compliance with the required pumping schedule outlined in Section 1003.3.5.5. However, if the facility is found to be contributing fats, oils or grease in quantities sufficient to necessitate increased maintenance of the sanitary sewer system to prevent line blockages, backups or overflows, existing grease interceptor(s) must be replaced. If it is deemed that those facilities that consist of smaller, point-of-use grease interceptors cannot meet the sewer system requirements with improved maintenance, they must be replaced by the exterior large-capacity grease interceptors as outlined in Section 1003.3.5.
