The following LSPA practice tip was introduced at the June 2023 Membership Meeting, which was held in-person at the Westborough Doubletree hotel on June 20, 2023.  

Per 310 CMR 40.0006, Historic Fill cannot contain contaminants that are present as a result of on-site activities. If contaminants at a disposal site could potentially have originated from known historical operations or activities at the site, an LSP needs to first determine that contaminants are not from on-site activities before the contaminants can be attributed to Historic Fill.

Members of the LSPA’s Technical Practices Committee are creating a Work Group to review the documents listed below. 

• Background Levels of Polycyclic Aromatic Hydrocarbons and Metals in Soil Technical Update – May 23, 2002
• Historic Fill / Anthropogenic Background Public Comment DRAFT Technical Update – May 24, 2016

As part of this effort, the Work Group is reviewing the LSPA Comments on Historic Fill/Anthropogenic Background DRAFT Technical Update 2016, July 14, 2016, which were previously transmitted to MassDEP.
