DEP publishes this register as a PDF that stamps its own date, and that date is September 1, 2026. Businesses close, change hands and let licences lapse in that time, so this is a starting list, not a current register. Confirm the DEP Category C licence before you hire.
How this directory is built
Maine requires a DEP non-hazardous waste transporter licence in Category C — septage and holding tank waste — to pump a septic tank and haul the waste. This directory is that Category C list.
Of the 389 active non-haz transporters, 140 hold Category C. 122 have a Maine base city. 18 are based in another state and are counted but have no Maine county page. Category C is Maine's septage pumping credential, so nothing is filtered out by name — but portable-toilet, construction and municipal crews hold it too, so the 67 businesses whose name does not say septic or cesspool carry a note asking you to confirm household work first.
DEP publishes a city, not a county. Each city is mapped to a county from Maine's municipalities (and named villages to the town they sit in). That county is the business location, not a service area: a Category C licence is a state licence. DEP does not print a licence number on this roster; each card shows the published expiry instead.
