1. The purpose of this meeting was for the City to determine if
additional low interest SRF funding would be available for the
WWTP effluent pumping station, pipeline, and diffuser for the
Neuse River discharge, and if less stringent effluent limits could
be established for the Slocum Creek discharge in the interim while
a new "regional" WWTP is planned and constructed, since the
timetable for these facilities has accelerated due to the
expansion of the Cherry Point Marine Corps Air Station.
2. B&V reviewed two major changes in the situation since the 201
Facilities Plan was prepared a year ago for the WWTP expansion.
First, significant development projects have been presented to the
City's planning department for new housing and associated
facilities in response to the anticipated expansion of Cherry
Point. The developments were proposed after the City had
established the projected population given in the 201 Facilities
Plan. At this time a total of 1,280 units are in the planning
process for completion by 1998, plus 1,650 units have been
proposed by 2000. This equates to approximately 9,300 people and
would result in an increase in wastewater generation of over 1.0
mgd. This flow added to the present average flow of 1.15 mgd
means that the permitted capacity of the WWTP would be reached in
2000 and not 2005 as previously anticipated. The effluent
discharge would have to be relocated from Slocum Creek to the
Neuse River (Phase 2 of the recommended alternative) sooner than
provided for in the 201 Facilities Plan. In addition, the City is
beginning the master planning process to consider a new "regional"
wastewater treatment facility for start-up when the capacity of
the present treatment plant is reached.
Second, the DEM has recently proposed more stringent discharge
limits for the Neuse River. The proposed effluent limit for total
phosphorous has been reduced from 2.0 mg/L to 1.0 mg/L, and total
nitrogen which formerly had no limit now has a proposed limit of
6.0 mg/L. These stricter limits will require chemical

precipitation of phosphorous and denitrification for effluent
discharge, the same as is required for discharge to Slocum Creek.
These new proposed limits mean that Alternative 4 in the 201
Facilities Plan is not feasible, leaving only the selected
alternative (upgrade of existing treatment processes) or land
appl ication.
3. DEM indicated that the City should apply for a new permit for
discharge to the Neuse River. This permit would have two sets of
limits and two flow rates covering both an interim Phase 1
discharge to Slocum Creek and long-term Phase 2 discharge to the
Neuse River. It would also stipulate a date certain to change
over from discharging into'the creek to the river. DEM is
agreeable to a discharge of 2.25 mgd into Slocum Creek at the
current 1.5 mgd effluent limits as long as the City is proceeding
with work on a new "regional" WWTP. This consolidated facility
should consider treatment of wastewater generated from the Trent
River to Havelock.
4. Continuing with the 1.5 mgd effluent limits for discharge into
Slocum Creek means that denitrification filters would not
necessarily be needed in the existing plant expansion project.
Construction of a denitrification system (either filters or
biological nutrient removal, BNR) would be included at the new
"regional" treatment plant. If denitrification filters are not
provided at the present plant and it continues in service into the
future, the denitrification facilities at the new plant would have
to be sized large enough to handle all wastewater flows.
5. The City will need to submit an amended 201 Facilities Plan and an
environmental assessment for the Neuse River diffuser and
pipeline. Then the permit application can be submitted. The
application should request the ultimate discharge flow projected
for the existing plus "regional" treatment plants.
•
6. DEM indicated that there should be additional SRF funding
available, depending on Congress' reauthorization of the Clean
Water Act and the actions of the State legislature. Funding won't
be held for the City unless they are progressing with the project.
The possibility exists that the monies for the current project
could be increased to include the effluent pumping station,
pipeline, and diffuser for the Neuse River discharge (Phase 2) at
a low interest rate. The longest period suggested by DEM for
tying up funds for the City was two years, and this is only if

plans are in progress for the Neuse River discharge and/or a
"regional" facility.
7. Black & Veatch estimated that six months would be needed to
prepare the facilities plan and EA, including a public hearing.
The plan should address the change in population projection, look
at expansion at the present site, identify potential sites for a
new plant, and give the specific location of the discharge into
the River. DEM agreed to this timetable.
8. DEM is meeting soon with the Navy, and the City agreed to provide
a location map of the existing plant and surrounding area so that
DEM could inquire about available parcels owned by the Navy for a
possible expansion of the existing WWTP or parcels which may be
available for a new "regional" facility.
9. The City reported that they met earlier in the week with
representatives of the State and Federal government regarding the
potential expansion of Cherry Point. A final decision is due in
July. This information should be available in time to make a
final decision on accelerating the project schedule.
