The rule
“The industrial user must document each pump-out with a waste manifest or trip ticket which must be provided to the city as required and kept by the industrial user on site for at least three years,” with compliance shown “through a certification by the hauler included on the waste manifest or trip ticket for each load” (RMC 12.16.555(b)(6)(ii)f–g). The general record rule says the same: records kept “available for inspection for at least three years” (12.16.580(b)).
What ours carries
- Hauler name, license, and the operator’s signature — the certification
- Date, address, interceptor size
- “Full pump-out” with gallons removed
- Percent-full reading before service — your 25%-rule evidence
- Condition notes: baffles, tees, lids, access
- Disposal destination
The one-folder system
Trip tickets in date order, a copy of your EC permit with its cleaning frequency highlighted, your used-oil pickup tickets, and a page of notes for anything unusual. An inspection “with or without notice” is answered from that folder in thirty seconds.
