(C) At least one access manhole, with a minimum diameter of 24 inches shall be provided over each grease trap/interceptor chamber. Such access must be in an area accessible to city inspection staff at all times. The access manholes shall extend to at least the finished grade and be designed and maintained to prevent water inflow or infiltration. The manhole shall also have readily removable covers to facilitate inspection, grease removal, and wastewater sampling activities.
