A. Whenever deemed necessary, the superintendent may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sanitary sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this chapter.
B. The superintendent may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
C. A grease interceptor or a grease trap is not considered to be properly maintained if for any reason it is not in good working condition with all internal required plumbing of proper design and length in place, or if the operational fluid capacity has been reduced by more than twenty five percent (25%) by the accumulation of floating and settled solids, oils, and greases. The owner of any premises required to install a grease interceptor; the lessee and sublessee, if there be such; and any proprietor, operator, or superintendent of such facility are individually and severally liable for any failure of proper maintenance of such grease interceptor.
If the grease interceptor is not maintained adequately under the conditions of use, the grease interceptor shall be resized and the user shall install one which is effective in accomplishing the intended purpose.
When a grease interceptor/trap is cleaned, the sidewalls shall be scraped and hosed down, while all the solids and liquids contained are removed. All wastes removed from any grease interceptor/trap shall be legally disposed of other than to the sewer. The city of Pocatello specifically prohibits the following grease interceptor/trap practices:
1. Pumping to remove only accumulated sediments or floating materials;
2. Pumping operations which specifically separate floating or sediment interceptor solid wastes from wastewater and then return or decant the separated wastewater back into the grease interceptor/trap;
3. Transporting any hauled pollutants from another location for discharge into a grease interceptor/trap.
4. Use of grease interceptor/trap treatment products, including bacteria, designed to digest the grease, is specifically prohibited.
D. Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
