1) Passive Injection Systems -In-well delivery systems to diffuse injectants into the subsurface. Examples include
ORC socks, iSOC systems, and other gas infusion methods (Note: Injection Event Records (IER) do not need to be
submitted for replacement of each sock used in ORC systems).
2) Small-Scale Injection Operations -Injection wells located within a land surface area not to exceed 10,000

Dear Property Owner:

olrector
According to Union County tax records, you purchased the referenced site. In June 1988, a
petroleum release was discovered when a 550-gallon unleaded gasoline UST began taking on
water and the onsite supply well became contaminated. The incident was recommended to the
State -Lead Cleanup Program in 1991, and has been monitored since then as a Federal Trust Fund
site. The underground storage tanks were removed in 1992. Assessment activities conducted in
2016 confirmed that residual petroleum compounds remain in the soil and groundwater at the
site.
In order to remain in the State Lead CIeanup Program, please sign the attached Access Agreement
which gives us and our contractors permission to go on the property and work. Otherwise, you
will be responsible for the cleanup.
If you have any questions, please contact me at [phone] or sharon.8hiold'a rncdenr.gov.
