Toya - here's the note i sent to Larry awhile back. I'd just touch base with him before sending this letter
out. Talk to me if you need to.

We (I guess that would be me in this case!) think it's a terrific idea for those facilties to tie-in (but there
has been a lot of that talk over the past few years). If you can get Jonesville to commit to that in writing
(by Town Council/Mayor, etc. - I'd be willing to do that). But...the timing on that would also have to be
perfect - we would not grant the expansion phase for Elkin until Jonesville had tied -on. And we'd need
to document this in our files very well so we wouldn't accidently return it because it had no FONSI.
We could also caveat the permit to say that they (Elkin or YVSA) must proceed forward with the SEPA
process if they don't tie-in Jonesville and reduce the ultimate flow to the Yadkin (and they would also
have to justify all the flow). How does that sound?
These are my thoughts as far as the NPDES permit goes - I don't make the call on the SEPA criteria.
Give me a ring if I need to clarify further.

Yadkin Valley Sewer Authority (YVSA) is planning to submit a project to CG&L. I have
been asked to make a preliminary determination concerning whether or not the project
will. be subject to SEPA and require a FNSI (i.e. is it over the NCAC minimum criteria
threshold?). YVSA intends to construct an upgrade to the existing Town of Elkin
WWTP to accommodate the sewage from the Towns of Elkin, Jonesville, and Ronda,
NC. The project includes: (1) Upgrade of the Elkin WWTP to accept the flows from

the Towns of Elkin, Jonesville, and Ronda, (2) Transfer of the Jonesville's wastewater
flows across the Yadkin River to the Elkin facilities and (3) Rehabilitation of the
existing sewer systems to reduce inflow and infiltration.
The SEPA threshold for expansion of an existing WWTP is 0.5
MGD of additional capacity. YVSA's consultant engineer faxed
me information that indicates the Elkin plant will be expanded
from 1.8 to 2.5 MGD; however, the existing Jonesville 0.4 MGD
WWTP will be decommissioned, so the net expansion could be
considered as 0.3 MGD which is below the threshold. Can the
Elkin plant expansion NPDES permit be conditioned to require
the Jonesville WWTP to be taken out of service? If so, maybe the
WWTP expansion could be considered below the SEPA threshold
and a comprehensive environmental review with a FNSI would
not be required. I need to confirm the preliminary determination
with the NPDES Unit, before I discuss it with YVSA's
consultant.
Thanks!

Re: Elkin WWTP
Determination of Allowable Discharge
Dear Ms. Wilson:
DENR . WATER QUAufY
f'OiNT SOURCE 3RANCH
The Yadkin Valley Sewer Authority would like to construct an upgrade to the existing
Town of Elkin WWTP to accommodate sewage from the Towns of Elkin, Jonesville and
Ronda, North Carolina. The proposed project would upgrade the Elkin WWTP to accept
the flows from the three towns and would require the expansion of the existing Elkin
WWTP from 1.8 MGD to 2.5 MGD. For this upgrade, the 2.5 MGD proposed flow
would discharge to the Yadkin River at the location (approximate Latitude 36°14'51" and
Longitude 85°49'53") identified on the attached drawing.
In accordance with the Engineering Alternatives Analysis (EAA) Guidance Document,
we are requesting that an evaluation be performed to determine if the proposed discharge
is allowable at the proposed location and a determination of the associated speculative
limits.
If you have any questions, if you need additional information, or if I can be of further any
assistance, please don't hesitate to contact me at (704) 342-3000.
Sincerely,
HOBBS, UPCHURCH AND ASSOCIATES, P.A.
