Subject: Additional Information Request
Meadow Creek Business Park
Wastewater Collection System Extension
Stanley County
Dear Mr, Greene:
The Mooresville Regional Office (MRO) has conducted a preliminary review of the subject permit application
package, However, additional information is required before we can process your request. Please address the
following by no later than April 30, 2007.
1. The MRO must determine how available sewer capacity is shared by Locust and Stanfield. Please respond
with information regarding your current systems operational capacity,, your allocated projects (and flow) to
date, and any other information necessary to assess the current state of the tributary line shared by the Locust
and Stanfield sewer system. The MRO assumes that you have already evaluated the total capacity of the
tributary line and have determined how capacity for this line will be allocated until design capacity is reached.
The MRO recognizes that capacity agreements with the Oakboro WWTP are a separate issue from flow
tributary to the Main pump station. Please provide total design flow numbers associated with the force main
and the contract which tracks Locust and Stanfield tributary capacities. Future sewer collection system
applications will require a flow allocation letter signed by both Stanfield and Locust defining the design flow,
actual flow, and subtracting the total volumes from the available capacity of the tributary force main,
2. There are significant SSO issues associated with the Main pump station downstream of your shared force
main. Currently, the MRO is discussing corrective action plans for the pump station with the Town of
Oakboro. Please be advised that until the MRO is satisfied that the actions taken by Oakboro to correct these
issue are implemented tributary flow will not be permitted to the entire tributary system associated with the
problem pump station. It is recommended that Locust and Stanfield participate in corrective action plans for
the pump station because it is the only means of conveyance to the Oakboro WWTP at this time.
Please be aware that you are responsible for meeting all requirements set forth in North Carolina rules and
regulations. Any oversights not found in our review of the subject application package are still the responsibility of
the applicant, In addition, any omissions made in responding to the above items may result in future requests for
additional information or denial of the requested permit,

Dear Mr. Krebs:
Please consider this correspondence in association with your letter dated March 7, 2007 and in
consideration of our meeting on April 3, 2007. On behalf of the Town of Oakboro Board of Commissioners
I would like to relay my appreciation for you time and cooperation in this important matter. We all look
forward to solving this issue and feel that our most recent meeting with you and your staff was very
productive.
As you are aware the original response to your Notice of Violation (NOV) letter was submitted by the Town
on March 26, 2007 which was accompanied by a Technical Memorandum (both attached) prepared by our
office. Without repeating the contents of that transmittal l would restate the primary focus which included
three main issues: 1) Review of existing Oakboro WWTP treatment capacities,2) Quantification of WWTP
flow commitments and 3) Summary of improvements to Increase System Capacity.
As requested at the April 3, 2007 meeting we have developed quantitative measures and timeframes for
remedies to overflow conditions at the McCoy's Creek Pump Station. In that regard please find attached
our suggested Corrective Action Plan for your review and comment. Please note that several of the
proposed items are currently underway such as daily pump run monitoring, flow metering and field
investigations.
As a part of the Corrective Action Plan we have proposed a limited Inflow/ Infiltration project (Priority 3).
This limited project is based upon our Sanitary Sewer Evaluation Study (SSES) report dated June, 2005
and direct field observations by the Town of Oakboro. For your review please find attached a synopsis of
proposed repairs associated with this proposed project.
P.O. Box 1726 — 129 N. First St. — Albemarle, NC 28002 — 704-984-6427

Also for your use please find attached an overview map of the main sewers contributing to the Oakboro
wastewater collection system. This map depicts the various gravity sub -basins, pump stations, proposed
repair areas and other pertinent information related to the Oakboro system.
In closing I would again like to relay my sincerest appreciation for your cooperative attitude and for the
invaluable assistance of the Water Protection Section staff. We ail remain confident that we are moving
forward in the right direction and look forward to the results of the Corrective Action Plan. I am available at
your convenience to provide assistance or additional information.
Sincerely,

Dear Mr. Krebs:

�� r .-a to
Please consider this correspondence in response to your letter dated April 2, 2007 concerning the above
referenced subject matter more specifically dealing with the arrangement of flow allocation and tracking in
the shared Locust -Stanfield force main. On behalf of the City of Locust Board of Commissioners I would
first like to relay my appreciation for your time and cooperation in this important matter. Please be
assured that the City of Locust considers this a very critical issue and desires to move forward in
addressing your concerns in a most prudent and practical manner.
Before addressing your concerns I would like to provide a brief overview of "West Stanly" sewer
operations including the collection, transportation and final treatment of West Stanly wastewater. Both
Locust and Stanfield own and operate separate "Vacuum" sewer systems as manufactured by AIRVAC.
Locust also operates several gravity sewer networks. The vacuum systems collect wastewater via a
system of vacuum lines which conveys wastewater to central vacuum stations. Collected wastewater is
then discharged from the vacuum stations into a common 12" force, shared by Locust and Stanfield,
which delivers sewer flows from West Stanly to the Town of Oakboro (Overview map attached). All West
Stanly wastewater flows received by Oakboro are then routed through the "McCoy's Creek" pump station
for final pumping to the Oakboro wastewater treatment plant (WWTP). It should be noted that Locust is
currently sending approximately 65,000 gallons per day and Stanfield is sending approximately 30,000
gallons per day on average to Oakboro.
The original vacuum sewers, shared force main and improvements to the Oakboro WWTP were
accomplished in the mid to late 1990's. As appropriate, the three municipalities (Locust, Stanfield,
P.O. Box 1726 - 129 N. First St. - Albemarle, NC 28002 - 704-984-6427

OakbOro) entered into various and separate, lnterlocal Governmental Agreements for mutual benefit and
assurance of servFces. Notably, Iwo agreernents Were executed. An agreement between Locust and
O<akboro was executed on �tuty 5`�' 1995 (attached) setting forth, among other items, the provision of
wastewater treatment 'for Locust wasCewator by Oakboro. This agreement allowed for an initial "free"
capacity of 90,000 gallons per day and an allowance for an additional purchased capacity of 150,000
gallons per day for a 'total treatment capacity of 240 000 gallons per day. Based on Oakbora s permltted�
WWTP capacity of 0.9 million gallons per day thus level of ccmmltment represents 27",il of plant capacity.
Similarly it is my understanding that Stanfield has achieved a committed (free and purchased) capacity
amount of 150,000 gallons per day or 17 ' of WWTP capacity.
Of particular' interest, in reference to your most recert incFt iry, is the Interlocal Governmental Agreement
executed between the Town of Stanfield and City of Locust. This agreements signed on March 19'r, 1997
(attached) set forth the framework for the sharing of the 12' force man to include a 50`h undivided legal
and beneficial interest to both parties. It is stated in the agreement that the 5.0% ownership would apply
to construction costs, tap revenues, maintenance costs, etc, it is my understanding that the 50%
beneficial ownership would then translate to an equally shared 50% ownership to both parties for the
actual "capacity" of the force main,
in order to establish the capacity of the shared force main I have reviewed available "As -Built" drawings„
operations & maintenance manuals and have performed various field surveys and visits. Our office has
previously performed limited hydraulic modeling on various portions of the West Stanly force main
network prior to your letter. It appears that all existing vacuum stations were designed around a 750
gallon per minute (gp.m) discharge pumping rate, which would provide for a self -cleansing velocity of 2
feet per second in a 12' force man Our field observations indicate that the vacuum stations are
operating above the 750 gpm rate and more likely are producing upwards to 1200 gpm in some
instances. While not prepared to concretely establish a force main capacity by this writing I will
nonetheless relay that it is my position that the 12°` force main should be able to deliver approximately
1000 gallons per minute based on currently installed pumping capacity both ii Locust and Stanfield.
As you are aware there are many factors which can influence the total daily capacity of the force main
including available wet well storage, pump rum times, pumping capacities, etc A total daily flew capacity
of approximately 1 rgallons per day could be achieved based on a total d'srlly pumping time of 16
hours* Obviously total daily force main capacity is highly influenced by peak loading and the ability of
facilities to accomrn+odate and buffer peak flows. It is my observation that constructed facilities are
operating as intended and appear to functioning well.
Another observation that is somewhat cbvious is the fact that there are multiple pump stations connected
to the 12" shared force main. Currently there are four rtaain stations contributing flow to the shared force
malnwhich are 1) Meadowcreek 'Vacuum Static) a 2) Browns Hill Road 'Vacuum Station, 3) Stanfield
Vacuum Station and 4) The Locust East Sanitary Pump Station. All four stations are capable of
2 of 4

delivering flow to Oakboro individually. The result of the multiple pump connections is that full utilization
of the 12' force main can not be achieved due to the inevitability of simultaneous pump operation and the
lack of flow equalization. We have had various discussions over the past several months concerning the
modification of pumping protocols out of West Stanly, Discussions have centered on the idea of a
regional pump station, located in the Locust) Stanfield area, to include flew equalization facilities, This
approach would substantially increase the shared force main capacity primarily through the provision of
flow equalization and extended pumping times. While this idea is not fully developed or yet needed we
are continuing to move forward with developing this concept.
The following table summarizes current capacities and utilization:

l have had discussions with City of Locust officials concerning the need going forward to provide for full
and accurate accounting of the shared force main capacity, It appears that this will not be an issue for
either municipality and that efforts are underway to provide for this accounting system, Although a valid
concern for all parties it is evident from the above tabulation that neither Locust nor Stanfield are in
jeopardy at this time of exceeding their flow allocation.
Z F A

I, as well as you, am aware of several pending developments that have expressed interest in the Locust
area which could impact the force main allocation. Although not in contractual form it would only be
prudent that the effecting municipality be responsible for abating any condition that would impact the force
main allocation arrangement. As discussed above we feel that a regional pumping station with flow
equalization will be inevitable which will provide for increased force main capacity for both Locust and
Stanfield, Efforts in this regard should be initiated later this year.
On Friday, April 13`h, 2007, the Town of Stanfield, Town of Oakboro and the City of Locust held a joint
meeting which included various local officials. The tone of this meeting was very cordial with all relevant
West Stanly sewer issues brought to the table. Items discussed included shared force main capacity,
growth, accountability, and more importantly the need to re-establish dialogue on pertinent sewer issues
relating to all three municipalities. It is was my understanding that from this meeting all parties have
agreed to examine related issues on a regular basis.
Again, thank you for your time and consideration. Please do not hesitate to call should you need
additional information. 1 look forward to hearing from you and moving forward.
