Subject: Renewal of Existing Injection Permit #WI0400098 Without Modification
Former Flakt Products Site
2000 Lowery Street
Winston-Salem, North Carolina
Wood Project Number 3031052007
Dear Mr. Rogers:
On behalf of ABB, Inc. (formerly Flakt Products, Inc.), Wood Environment & Infrastructure
Solutions, Inc. (Wood) is submitting two copies of the enclosed Application for Permit to
Construct and/or use a Well(s) for Injection for the former Flakt Products site in Winston-Salem,
North Carolina (Site). As discussed with Ms. Shristi Shrestha on October 14, 2020 and
summarized in emails to her and you on October 15 and November 9, since the previous permit
renewal no injections have occurred because ABB was monitoring groundwater plume stability
as part of pursuing a risk -based closure for the site. In March 2020, the NCDEQ IHSB indicated
to ABB their concurrence that the remaining groundwater plume was stable, and that ABB could
pursue a risk -based closure. More recently, however, the site property owner (City of Winston-
Salem) indicated they are not amenable to land use restrictions required as part of a risk -based
closure. Therefore, ABB plans to continue annual groundwater monitoring and reporting.
Details of previous injection events are documented in Injection Event Records on file with the
NCDEQ, while the most recent reported site groundwater conditions are documented in Wood's
February 5, 2020 Annual Progress Report on file with NCDEQ (NONCD 000 0017).
While ABB has no plans to perform another injection near -term, because a risk -based closure
does not appear to be an option at this time they desire to renew the injection permit should the
need for another injection arise. Ms. Shrestha indicated that ABB should submit a Renewal of
Injection Permit Without Modification, and if ABB decides another injection is warranted, they
will then submit an Injection Permit Modification.
In keeping with the permit requirements Wood will submit Injection Event Records following any
additional injection event and will submit a final project evaluation within nine months of
completion of all injection related activities.
