The FOG waste discharge permit (FOG WDP) is a legally binding agreement issued to an FSE, FM/P or commercial and industrial businesses or other entities subject to the provisions of this chapter to utilize the city public sewer collection system under the terms, conditions, and criteria of the city's FOGCP. The FOG WDP is prepared and maintained by the city, and its provisions may be modified periodically as required to ensure each wastewater discharger's compliance with the terms and conditions of this chapter, as they may be amended from time to time.

B. In addition to the FOG WDP, the city may also issue specific permit conditions to any FSE, FM/P or commercial and industrial businesses or other entities subject to the provisions of this chapter. In the event that the city issues specific permit conditions, the basis for those specific permit conditions shall be disclosed in writing and appended to the FOG WDP.
