Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
On August 2, 2022, Alex Lowe of the DWR WSRO conducted a routine pretreatment compliance
inspection at the City of Greensboro's T.Z. Osborne WWTP. Onsite representatives present were
Amy Varinoski (Pretreatment Coordinator), Martie Groome (Lab & Industrial Waste Supervisor), Bill
Burdick (Compliance Specialist), and Alicia Goots (Lab Coordinator).
A review of the pretreatment program elements indicated that all program elements have been
updated an submitted to the State; both the headworks analysis (submitted February 15, 2022) and
the enforcement response plan (submitted March 1, 2022) are still awaiting approval.
Compliance files were reviewed for three SIUs: Qualicaps, Lanxess, and Ecolab. Ms. Varinoski noted
that Lanxess was found to be the source of the 1,4-dioxane exceedence reported by the WWTP in
April of 2022, and will be responsible for paying the fine associated with the SOC once it is assessed
by the State.
Ms. Varinoski also explained that Ecolab was held responsible for a large upset at T.Z. Osborne after
it was reported that concentrated anti -bacterial material was accidentally discharged from their
facility. The root cause was determined to be a drainage valve on the containment area that was left
open during the delivery of raw materials, coupled with a small leak in the hose used to offload the
chemical from truck to storage tank. Ms. Varinoski noted that the SIU has been fully cooperative in
remediating the issue, and will take full financial responsibility to replace the bugs killed off in the
discharge and cover the cost of civil penalties from the State.
Lastly, Ms. Groome shared that she will be retiring from her position at the end of August 2022. She
will return to the city sometime in October 2022 on a part-time basis as a special projects manager
working to maintain progress on the 1,4-dioxane SOC.
No instances of non-compliance were uncovered during this inspection, and as such this program is
considered stisfactory.
