Maryland Septic Hauling Compliance Guide

Maryland imposes the longest record retention requirement in the country for septage haulers. Under COMAR 26.04.06.25, all transport records must be kept for 10 years — double the federal default and significantly longer than the 3 to 5 years most states require. For a hauler generating hundreds of manifests per year, that means maintaining a decade of accessible, organized documentation at all times.

The Maryland Department of the Environment issues Sewage Sludge Utilization Permits under COMAR 26.04.06, with annual reporting required on a calendar-year basis. Registration is per business, not per vehicle. Manifests must include five fields: generator name, date and time of disposal, gallons, source location, and a waste description. That waste characterization field is specific to MDE and goes beyond the simple waste-type checkbox many states use.

Penalty exposure in Maryland is structured in tiers. Under Environment Article Section 9-269, each individual violation can carry a fine up to $1,000, capped at $50,000 aggregate. But continuing violations — operating without a permit, repeated manifest failures — escalate to $10,000 per day. The combination of a 10-year records window and per-day continuing penalties means that documentation gaps discovered years after the fact can still generate substantial fines.

Grease trap waste does not require a separate state license beyond the MDE sludge utilization permit. FOG compliance is handled at the municipal level through local pretreatment programs under 40 CFR 403.
