Good morning Sue,
Thank you for your questions regarding the Asheville Airport Structural Fill. We hope these responses answer your
questions. Overall, the Division of Waste Management — Solid Waste Section has approved the closure cap design
construction. However, approvals are still pending from E&SC and stormwater (DEMLR).
Questions:
"Is it appropriate for me to assume that DWM is addressing/reviewing all possible sources of "contaminated" runoff
from the project and requiring any appropriate controls?"
Per Division of Waste Management — Solid Waste Section Water Quality Monitoring and Reporting Permit dated
December 14, 2020, Area 3 and 4 are subject to 30 years post -closure (water quality monitoring and reporting) starting
on September 16, 2015 and January 15, 2015, respectively. Additionally, the permit covers five years of closure and
post -closure water quality monitoring and reporting of Area 1. Per the Water Quality Monitoring and Reporting Plan,
groundwater and surface water will be sampled and analyzed on a semi-annual and quarterly basis, respectively and
occur throughout the post -closure care period. Groundwater and surface water are subject to 2L and 2B standards,
respectively. This includes provisions for detection monitoring, assessment and corrective action.
"So I assume you're looking at groundwater, but once the cap is in place it looks like all surface water will be directed
to the stormwater basins and then streams, so does that mean that DWM is ensuring that any surface runoff to those
basins is "clean"."
Per the Section's Permit, condition 9a spells out at a minimum requirements for surface water testing required following
installation of the cap.
"Are you at all looking at the design and/or sizing of those stormwater basins as part of your review? "
Stormwater basin design and sizing is not under the purview of Solid Waste.
Please let us know if we can be of further assistance.
Regards,
Sarah

Hi Larry,
I'm working on the DWR 401 Certification for this project. I was hoping you could answer a couple questions for me so
that I can just make a note in the file and process the application. I don't know enough about your program to be
certain without asking.
Part of the DWR 401 review is to ensure that downstream water quality violations don't occur. In this situation, is it
appropriate for me to assume that DWM is addressing/reviewing all possible sources of "contaminated" runoff from the
project and requiring any appropriate controls? I saw monitoring wells in the plans so I assume you're looking at
groundwater, but once the cap is in place it looks like all surface water will be directed to the stormwater basins and
then streams, so does that mean that DWM is ensuring that any surface runoff to those basins is "clean". Are you at all
looking at the design and/or sizing of those stormwater basins as part of your review? We normally would but I wasn't
sure in this case if you guys did for some reason. Thanks for your help. If talking via phone is easier please fee free to
call either of my numbers below.
