The following LSPA practice tip was introduced at the April 2026 Membership Meeting, which was held via Zoom on Tuesday, April 14, 2026, from 3:45-5:00 PM.

Practice Tip  
There can be more than one LSP-of-Record for a disposal site. As defined in the MCP (310 CMR 40.0006), an LSP-of-Record is an LSP “…who has rendered an LSP Opinion [at a] site, …”  and remains as such until they provide written resignation to MassDEP. In cases where there are multiple LSPs-of-Record, it may be beneficial to coordinate activities with other parties performing response actions.
