Glossary & Frequently Asked Questions
This glossary is designed for EHS managers, facility managers, and compliance professionals responsible for managing regulated waste under U.S. federal environmental regulations. State requirements may be more stringent.
A
Accumulation Start Date
The accumulation start date is the date hazardous waste first begins accumulating in a container or tank. This date determines how long waste can legally remain on-site before shipment under RCRA generator requirements.
Missing or incorrect accumulation dates are among the most common inspection findings—especially during facility cleanouts, turnarounds, or shutdowns—because inspectors often compare container dates with shipping records and manifests to verify compliance.
Common Questions
- When does the accumulation clock start?
- Do satellite accumulation containers need start dates?
- What happens if the date is missing or wrong during an inspection?
Asbestos
Asbestos is a regulated mineral fiber historically used for insulation, fireproofing, and durability in industrial and commercial buildings. It is commonly found in pipe insulation, boilers, floor tiles, roofing, fireproofing, gaskets, and older equipment. While most new uses are prohibited, asbestos remains a major compliance issue during maintenance, renovation, and demolition.
For EHS and facility managers, asbestos matters because disturbing asbestos-containing materials can release airborne fibers, trigger OSHA and Clean Air Act requirements, and shut down projects. Many states enforce stricter rules than the federal baseline, especially around notification and disposal.
