RE: Restrictive Covenant - Motor Pool
recommendation
BOARD ACTION REQUESTED:
Sign and Notarize the Restrictive Covenant - Motor Pool
BACKGROUND:
On October 3, 2019, Genesee County submitted a suspected release based on inventory records and petroleum odors. The dispenser that was detected to have the loss inventory was shut down and locked until it could be fixed. On October 7, 2019, Mid-Michigan Station Services (Mid-Michigan) was on-site to perform an inspection of Dispenser 2. Upon investigation, a very small leak was found and repaired at the dielectric union. On October 14, 2019, Atlas was on-site to collect soil samples below the dispenser. The dispenser had no sump.

Based on that data, a Confirmed Release Report was submitted to LARA. On October 18, 2019, LARA upgraded the suspected release to a confirmed release, with a release number C-0225-19.

On January 31, 2020, all monitoring wells were gauged and groundwater samples were collected from monitoring well MW-2 via low-flow sampling procedure. All other monitoring wells could not be sampled because they were dry.
