EPA, RCRA and DOT paperwork, computed from the record.

The material profile data sheet carries identity, the soil determination with its analytical tests, regulatory status, chemical composition and physical properties. It prints as the document a generator signs and a facility files, and a client's whole profile book downloads as one PDF.

Inner container size limits and gross weight are validated at the drum build. Prohibited materials — poison inhalation hazard, 6.1 PG I, temperature-controlled — are flagged with the reason and shipped as their own container. Compatibility cautions are at the category level: category pairs that must not share a drum are flagged. Mercovi does not claim a chemical-level compatibility matrix.

Computed from the waste codes — any RCRA code makes it a Uniform manifest. Continuation sheets when the lines run over. One manifest per designated facility, which is why a job can need more than one. Transporters carry their state registrations with expiry dates.

Each manifest carries its EPA e-Manifest status, submission method and tracking number on the record, so the MTN is where the job is — not in an inbox. How e-Manifest works sets out who signs what; a contractor that prepares manifests for its clients is a broker.

Carried per container from the paperwork, not from the date it arrived at your door. Repackaging does not reset it: a consolidated container takes the earliest parent's start date.

There is no one number of days. Which clock governs a container depends on the facility's status, the generator's status and the state.

The transfer facility exemption (40 CFR 263.12). A transporter may hold manifested containers at a transfer facility for a limited period without a storage permit. This is the clock most HHW contractors actually live under when a load comes back to the warehouse.

Generator accumulation (40 CFR 262). The limit depends on generator category — LQG, SQG, and distance to the designated facility — and VSQGs are capped by volume rather than time. The regulatory artifact is the accumulation start date on each container, and the clock starts at the first drop, not when the container is full.

Permitted TSDF storage. The permit sets the limit. There is no single federal number.

Because the governing limit depends on the facility's status, the generator's status and the state, Mercovi stores no day count in code. Each facility carries its own ordered rules and the first rule that matches a container governs it.

Returned onto the shipment and onto every source generator's record. Where a client's terms require it, the certificate is attached to the bill.

Jobs, manifests, profiles, receipts, shipments, certificates and bills are retained as records, and every document — manifest, profile sheet, dispatch sheet, load order, pack list, receipt sheet, bill, report — is an output of the record rather than something assembled alongside it. Issued bills lock their lines; closed jobs lock their counts.
