 Nationally and statewide: More focus on proper grease interceptor cleaning and service frequency rather than sampling to judge compliance  Sampling interceptors is a tool: Helps to measure performance and efficiency of the grease interceptor  Useful information for chronic problem areas

 Grab sample: Only collection method recognized for compliance determination by EPA  Collection – Typically a wide mouth 1000 ml glass container is used, depending on the lab used: dip and take method; Not recommended to transfer sample to another container
