The words on the paperwork.

The unique number printed on a hazardous waste manifest, assigned when the manifest is created, that identifies that shipment on every copy and in EPA e-Manifest.

In Mercovi the MTN lands on the manifest record, on the job it belongs to, and on the client's portal — so a tracking number is found by opening the job, not by searching an inbox.

The characterization document for a waste stream: its identity, chemical composition, physical properties and regulatory status, which a designated facility reviews before it will accept the stream.

A full profile per stream that reads on screen, prints as the document a generator signs and a facility files, and downloads as PDF. A client's whole profile book comes out as one PDF. See profiles.

A facility permitted under RCRA to treat, store or dispose of hazardous waste. The permit sets the terms, including how long waste may be stored.

The Facility module tracks a TSDF's container inventory, consolidation with lineage, outbound shipments with the facility as offeror, and the certificates of disposal returned to each generator. The storage clock follows the facility's own rules, because there is no single federal number.

The facility named on the manifest as the shipment's destination — the TSDF, or the recycler or transfer facility, that will receive the waste.

Each waste stream in the catalog carries its designated facility and that facility's approval number. One manifest is created per designated facility, which is why a job can need more than one.

The three federal generator categories under 40 CFR 262, set by how much hazardous waste a site generates in a month. Each category carries its own accumulation rules; a VSQG is limited by volume rather than time. HHW collection events typically run as VSQG days.

The client record carries the generator status and who the generator legally is — the client, the site or the contractor — and the facility's clock rules can key on it.

The date the first drop of waste entered a container. It is the regulatory artifact the generator accumulation clock runs from — it starts at the first drop, not when the container is full.

Carried per container from the paperwork, not from the date it arrived at the facility. Consolidating two containers gives the new one the earliest parent's start date; repackaging never resets it.

A location where a transporter holds manifested hazardous waste during the normal course of transportation. Under 40 CFR 263.12 a transporter may hold manifested containers there for a limited period without a storage permit.

The clock most HHW contractors actually live under when a load comes back to the warehouse. In Mercovi it is one of the three clocks a facility's ordered rules can apply.

The party offering a hazardous materials shipment for transportation and responsible for its description, packaging and manifest. On an outbound manifest from a facility, the facility is the offeror.

A facility ships consolidated containers out on one manifest with itself as the offeror, with the manifest's e-Manifest status and tracking number on the record.

The category-level proper shipping name — such as "Waste flammable liquids, n.o.s." — that a lab pack drum ships under, because the drum holds many chemicals of one hazard class rather than a single material.

Each lab pack category carries its generic PSN. The manifest writes one line per drum category using it, with the waste codes unioned from everything in the drum. See lab pack.

An outer packaging — typically a drum — holding many small inner containers of compatible laboratory chemicals, packed with absorbent, under the conditions of 49 CFR 173.12: inner container size limits, gross weight limits, and materials that may never ride in one.

The walkthrough records each chemical; the drum build packs by category and validates inner size and gross weight; prohibited items are flagged with the reason and shipped as their own container.

The signed confirmation from the receiving facility that a shipment was treated, destroyed or disposed of, returned to the generator for its records.

Lands on the outbound shipment and on every source generator's record. A client whose terms require it gets it attached to the bill.

EPA's national electronic system for tracking hazardous waste shipments, in which manifests are created, signed and corrected electronically and each carries its manifest tracking number.

Each manifest carries its EPA e-Manifest status, submission method and tracking number on the record. How e-Manifest works.

The shipping document that must accompany hazardous waste from the generator to the designated facility, with a continuation sheet (8700-22A) when the lines run over.

The form is computed, not chosen: any RCRA code on a waste makes the manifest a Uniform manifest. See manifests.

The EPA codes that classify a hazardous waste: D codes for characteristic wastes (ignitable, corrosive, reactive, toxic), F and K codes for listed process wastes, P and U codes for discarded chemical products.

Codes live on the waste stream in the catalog. On a container they are never typed — they are always the union of its contents, so a bulked drum cannot miss one.

The paint stewardship program, operating in participating states, that funds the collection and management of leftover architectural paint.

A client's PaintCare participation is on its record, and PaintCare is stated separately on the bill and the report.

The scale's printed record of a container's or load's weight, referenced by number on the collection record and the manifest.

C&I collection is one row per container that comes off the site — count, scale weight and weight ticket number — and completing the pickup prices it.

Field testing used to categorize an unknown or unlabelled chemical by its hazard class so it can be packed and shipped.

An item waiting on Hazcat is tracked as an unknown and cannot be categorized or packed until it is answered. The count of what is still unknown is on the job record.
