Southern Nevada Health District Criteria Interceptor Requirements - Grease Interceptors

After the Clark County Building Department has determined that a grease interceptor is required, the unit is to be installed outside the building.

Alternative Methods

Alternative methods of grease disposal, commonly referred to as grease machines, may be located within food establishments with prior approval from the Health District.

When it is determined that an outside grease interceptor cannot be used, the following criteria will be applied:

1. The food establishment must obtain prior approval from the Building Department regarding the size and capacity of the grease machine to be installed. (Note: The Health District cannot verify proper and acceptable location without knowing which unit/size of unit required.)
   
   
2. Newly constructed or remodeled food establishments: The grease machine shall be located in a room separate from that in which food is prepared and where utensils and tableware are washed, or in an area that is physically divided and protected by a wall that is at least 36" in height.
   
   
3. Existing facilities with no remodeling or construction that are seeking to enhance existing grease removal: A location acceptable to the Health District shall be based upon the establishments available and adequate floor space for the unit that has been pre-approved by the Building Department. The unit must be installed so as to be protected from all splash and spillage. The unit must be installed behind a moisture resistant structure approved by the Health District and installed in a manner that allows for easy and thorough cleaning.
   
   
4. The food facility must show proof of having contracted with an authorized company, or designate an on-site person, to be responsible for the daily maintenance of this unit. A daily log must be maintained by the company/individual responsible for maintenance, and this log must be made available for review by the Health District.
   
   
5. When approval by the Health District is required, a Building Memo Release will be provided by the Health District to the Building Department.
