Maine · Hancock County
13 businesses are based in Hancock County on the DEP Category C transporter list dated September 1, 2026.
DEP has not replaced the active non-haz transporter PDF since that date. Businesses close, change hands and let licences lapse in that time, so treat this as a starting list rather than a current register. Confirm the Category C licence is still current before you book.
Maine requires a DEP Category C non-haz transporter licence to pump a septic tank and haul the waste. DEP publishes a base city, not a county and not a promised service area; the county here is where that city sits. Each card also shows the expiry DEP printed on this roster.
These businesses give base cities around BAR HARBOR, BUCKSPORT, DEER ISLE, ELLSWORTH, LAMOINE, OTIS, SOUTHWEST HARBOR, SULLIVAN, WALTHAM. DEP publishes a business name, address, city, state, phone, Category C and an expiry date, and the list itself is dated September 1, 2026. DEP does not print a licence number on this roster.
Portable-toilet, construction and municipal crews hold this licence too. 3 of 13 here name septic or cesspool; the rest are flagged so you can confirm household septic tank pumping first.
