Dear Mr. Gore:

Subject: Updated Speculative Discharge Limits
NPDES No. NCO024210
High Point Eastside WWTP
Guilford County
This letter is in response to the request submitted by James Cramer of Hazen and Sawyer
for updated speculative limits for the proposed expansion of the subject facility from 16 MGD to
26 MGD. The Division of Water Quality (DWQ) previously provided speculative limits in
September 1995. These limits are being updated to incorporate the Hearing Officers'
recommendations for point source controls for the proposed Randleman Reservoir, based on the
public hearing in September 1998. Specific updates to the speculative limits include: 1)
relocation of the High Point-Eastside discharge point from the present location on Richland
Creek to a point downstream of Freeman Mill Dam; 2) effluent limits for phosphorus at the
outfall relocation point will be set at a monthly average of 0.5 mg/I at a maximum flow of 26
MGD; and 3) waters of the proposed Randleman Reservoir be reclassified as a water supply.
The updated speculative limits for the proposed expansion to 26 MGD with the relocated
discharge are presented in the attached Table A(1). These speculative limits are based on our
understanding of the proposed expansion and of present and anticipated fixture environmental
conditions. These speculative limits are not binding unless they become part of an issued
NPDES permit. Response to a speculative limit request does not guarantee that the Division will
issue an expansion of an NPDES permit to discharge treated wastewater into these receiving
waters, or that the effluent limitations and other requirements included in any permit will be
exactly as presented here. For example, the speculative limits do not include monitoring other
than influent and effluent samples. However, additional instream, reservoir, and/or end -of -pipe
monitoring will likely be added when the permit is drafted. In addition, updated information
may cause the toxicant limits to be eliminated or added as deemed appropriate.
It has previously been noted that the proposed expansion requires the preparation of an
environmental assessment (EA) by the applicant. DWQ will not accept a permit application for a
project requiring an EA until the document has been approved by the Department of
Environment and Natural Resources and a Finding of No Significant Impact (FONSI) has been
sent to the state Clearinghouse for review and comment.

the permit is not tied to the reservoir being built except that the recommendation to move the discharge
1.5 miles was based on the need to protect the reservoir's upper arms. If there were no reservoir, hiigh
point could argue that they did not need to move the discharge.
Tom Belnick wrote:
Boyd- I'm revising the spec limits for the High Point-Eastside WWTP. My
question is- could this expansion occur without the reservoir being
built? When I read the spec letter issued in 1995 the answer would be
"yes", since it stated that the spec limits would be applied with and
without consideration of the proposed reservoir. However, when I look
at the recent Hearing Officers Recommendations, the agreed upon TP limit
of 0.5 mg/1 is based on relocation of the discharge, and WS
classification of the reservoir, which implies that the expansion will
be tied in with the reservoir.

should probably discuss at Office hours (next Tuesday morning), but I'd
like you to represent permitting in this effort. Thanks,

As you know, Bradley, Steve Z, Lin, Preston and I met with Streb\�1
Boynton, Lee Burnette, and Wendy Fuscoe about what the Randleman rules •�
would require them to do regarding stormwater. John Kime also sat in.
The meeting went smoothly and High Point seemed pleased with our `
positions. Basically they were unsure of what a comprehensive
stormwater plan would be. They were afraid it would be a detailed Y
engineering plan to control all stormwater. We explained we basically
wanted to see evidence that they were going to have a viable stormwater
program which would demonstrate progress on all the areas we listed in
the rules, such as planning, education, illegal discharge and etc. They\
also wanted to know how we would consider their future requests to allow +_
above 50% impervious in the lower parts of their jurisdiction. We \
explained we wanted their ordinances to contain criteria needed to
approve projects such that we could approve the ordinance and they could
review projects. We emphasized we did not want to be reviewing
individual projects - unless they were for a major variance. Of course,
they showed their leanings toward regional ponds and we tried to point
out to them that that alternative was not the total solution and it was
frought with problems. They said they would be getting back with k
Bradley with some proposals.
There was some discussion about what was a stream. Preston a
explained that they should try to wait until the General Assembly came
up with options on the Neuse before going too far in that area. I r\ "y`11,
should also note that there was confusion on whether to use either the
soil maps or the USGS maps to define a stream. John Kime said most (1
thought the rules said that either applied. They actually say that in
deciding what is a stream, its a stream if it's one either of the maps.
�i
High Point wants to find out exactly where the discharge point is
so they can do the engineering analyses. We suggested that a modeller,
and probably someone from permitting, go out to the field with our field
office staff and High Point staff and find the site that best fits our

needs. They also had questions about the design of the discharge pipe
and size. They said they thought you had talked to someone already
about these issues and they would pursue those same channels. _
