What MassDEP has recorded
- RTN 3-0032323 — Offsite Heating Oil Release, tier classified (active), status TIER1D · MassDEP file
- RTN 3-0032323 — Offsite Heating Oil Release, activity and use limitation, status TIER1D, class PA, AUL recorded July 25, 2014 · MassDEP file
Within about 500 m (a third of a mile): 2 active tier-classified 21E sites and 12 sites with an Activity and Use Limitation. All MassDEP sites in Chelsea.
What this means
- Assessed 53% below the median apartments with four to eight units in Chelsea ($1,115,000, 123 parcels).
- An Activity and Use Limitation is a deed restriction: it limits how the land may be used (often no residential use or no digging) and passes to every buyer.
- A tier-classified site is a release still being cleaned up under the Massachusetts Contingency Plan; the MassDEP file shows the stage reached.
