Arbor Hills Monitor

Several EGLE-regulated facilities sit on and around this one site, including the landfill, its groundwater Remediation Area, the Arbor Hills Energy plant, and the Emerald RNG plant. This project checks the state's public filing systems for every one of them each day, reads what's filed, and keeps a running, dated record of what it finds.

Public Records

Every document the monitor has read, from the earliest record to the most recent filing.

The code

The monitor's pipeline and classification rules, open source on GitHub.
