To present to the BOCC: a) a report on Chatham County's request to access its Jordan Lake water
supply allocation through OWASA's Jordan Lake property and approved water supply intake site as
well as responses from the Towns of Chapel Hill and Carrboro to OWASA relative to that request; and
b) for the Board's review, revision and approval, a draft letter from the BOCC to OWASA outlining the
County's response to the Chatham request.
BACKGROUND:
On October 1, 1998, elected and appointed officials and staff from Carrboro, Chapel Hill, Hillsborough,
Orange County and OWASA met with elected officials from Chatham County at the OWASA offices in
Carrboro to discuss utility, planning and watershed protection issues of concern to all. The primary
issue discussed was Chatham County's inability to obtain a sufficient supply of raw water from Jordan
Lake through the existing intake structure, pumping system and raw water mains on the east side of the
lake (controlled by Cary and Apex). Margaret Pollard, Chair of the Chatham BOCC indicated that it
was unlikely that the equipment in the existing intake system could or would be upgraded to meet
Chatham's raw water demands. Ms. Pollard also indicated that the most viable solution apparent to
Chatham would be for Chatham to withdraw water using the approved intake site on the western side of

provide the funding necessary to accomplish the construction and to provide the operation and
maintenance costs. Mr. Fransen indicated that his own agency is split as to whether the state should
undertake the responsibility for owning and operating the intake/pumping facility.
Complicating the process under which the state could and would take responsibility for the western
intake are a number of additional concerns and political pressures relative to the entire Jordan Lake
allocation and withdrawal process from jurisdictions downstream of Jordan Lake. These jurisdictions
are concerned about the assimilative capacity of the Cape Fear (for discharges of treated wastewater) and
the effect of Jordan Lake instream flow augmentation releases and allocations on that capacity. It is
likely that there will be at least some political level opposition from these jurisdictions and their
legislators to anything that would facilitate withdrawals from Jordan Lake (as opposed to allowing the
water to be released for instream flow augmentation).
In conclusion, there does not appear to be any potential for developing a regional solution to the western
Jordan Lake intake/pumping facility issue that would be sufficiently prompt to satisfy Chatham County.
It appears that Chatham options will include: a) depending on the state to convince Cary and Apex to
provide more water from their intake/pumping facility; b) negotiating an arrangement with OWASA for
constructing anintake/pumping facility; or c) constructing their own intake/pumping facility.
RECOMMENDATION: The Administration recommends that the BOCC:
1. Receive and review the attached material including the draft of the letter providing input to
OWASA
2. Identify the major issues that the BOCC wishes to address, including any new issues raised in the
Engineer's notes
3. Direct staff to revise the letter as necessary to accurately reflect BOCC intentions
4. Direct the staff to bring the revised letter back for BOCC review and approval (at a future
meeting)

Dear Mr. VanderMeer:
The Orange County Board of Commissioners offers the following comments regarding the
local water supply and water quality protection issues discussed at the October 1, 1998 meeting
involving Orange and Chatham Counties, the Towns of Carrboro, Chapel Hill and Hillsborough,
and OWASA.
Cleazly our region's explosive growth makes it imperative that all local jurisdictions work
together to protect the quality of all of our natural resources and promote the most
environmentally sound usage of those resources.
Orange County is located in the upper portions of a number of important and
environmentally sensitive water supply river systems. Consequently we aze acutely conscious of
the need to be judicious in our efforts to be good stewazds of our available water resources, and
of the need to work with the local governmental jurisdictions within and adjacent to Orange
County to develop the strategies and accomplish the goals consistent with that stewazdship.
In accordance with this philosophy, the Orange County Boazd of Commissioners
commends OWASA on its efforts to bring stakeholders in local water supply issues together to
discuss issues of mutual concern. Relative to the issues raised at the October 1 ~` meeting, the
Boazd of County Commissioners is of course interested in facilitating a solution for Chatham
County's water needs. Since there have been additional discussions on this issue since
October 1 S`, it would be very helpful for Orange County to receive clarification concerning the
options open to Chatham County at the present time, including Chatham County's preferred
solution. If an intake on the western side of Jordan Lake is the preferred option, then Orange
County would be interested in having discussion with OWASA; state and federal authorities
controlling access to and allocation of Jordan Lake water supplies; other local jurisdictions
having interest in Jordan Lake's available water supplies; and Chatham County, in consultation
Mr. Daniel C. VanderMeer

with the Authority's constituent governments, to explore the use of OWASA's property as a
potential intake side to provide access to Jordan Lake water supplies for Chatham County while
still ensuring that OWASA's potential access to its Jordan Lake allocation is preserved.
The Orange County Boazd of Commissioners is ready to join all existing and potential users of
Jordan Lake water supplies in studying, developing and implementing effective watershed and
water quality protection strategies. The Orange County Boazd of Commissioners is similarly
ready to work with Chatham County to discuss, develop and implement enhanced watershed and
water quality protection strategies for University Lake water supplies.
If I may provide any additional input or staff assistance, please contact me at your eazliest
convenience. I would appreciate your advising the Boazd of County Commissioners when
OWASA has ascertained the range of options for meeting Chatham County's water needs,
including their preferred option.
Sincerely,

Dear Mr. VanderMeer:
p ~c~~od~
DEC S 1998 D
At the October 1" joint meeting between the local governments and the OWASA Board, it
was determined that each local government would discuss a number of issues raised by
Margaret Pollard, Chair of the Chatham County Board of Commissioners. It was further
determined that each jurisdiction would provide guidance to OWASA
Pursuant to that discussion, the Carrboro Board of Aldermen and I have discussed Chatham
County's request for cooperation on water-related issues.
First, it should be noted that the Carrboro Board of Aldermen is interested in being a good
neighbor to our friends in Chatham County. We believe our future is closely connected to
theirs and that it is in the best interest of all parties to cooperate whenever and wherever
reasonably possible.
Second, with regard to the specific issued raised at the October 1` meeting, we provide the
following input for your consideration:
a) Carrboro does not support the notion of OWASA extracting water from
Jordan Lake for consumption by OWASA customers.
b) Carrboro could support sharing water with Chatham during emergencies.
c) Carrboro supports developing a policy, which would allow Chatham County,
access to Jordan Lake water via OWASA'S intake rights. We acknowledge
that there are any number of considerations that must be explored to ensure
that the interests of all parties are secure.

SUBJECT: Discussion Paper on Jordan Lake Water Supply Options for OWASA
Deaz Mr. Givens, Dr. Gordon, Mayor Johnson, Mayor Nelson, and Mayor Waldorf:
The OWASA Boazd of Directors has requested me to send the attached discussion paper to all
local government participants in the October 1, 1998 "Jordan Lake as a Regional Resource"
meeting.
We believe that further collaboration between OWASA and Chatham County offers resource
management, environmental, and economic benefits that will not be realized if future Jordan
Lake water supply decisions are based only on the needs of individual users.
However, we request that you offer cleaz and concise policy guidance to OWASA so that we
may determine as soon as possible whether to proceed with, or defer, any further consideration
of joint efforts with Chatham County in this matter.
We look forward to your response and further discussion when we reconvene in Mazch 1999 as
agreed at our joint meeting of October 1, 1998.

Discussion Paper
Jordan Lake Options for OWASA
December 18,1998
What's the purpose of this discussion paper?
This paper provides follow up information to the "Jordan Lake as a Regional Water Source" meeting
among officials of Carrboro, Chapel Hill, Chatham County, Hillsborough, Orange County, and Orange
Water and Sewer Authority held on October 1, 1998. The OWASA Boazd of Directors discussed this
information at their December 10, 1998 meeting with the intent that this discussion paper would support
discussions of individual elected boards as they work with Chatham County on matters of mutual interest,
including collaborations or possible cooperation between OWASA and Chatham County on development
of water resources.
What happened at the October 1,1998 joint meeting?
A representative of the North Cazolina Department of Environment and Natural Resources provided an
informational presentation about Jordan Lake, the allocation process, its value as a regional resource, and
the expectation that only one water intake site will be developed on the western side of Jordan Lake.
Representatives from each of the local entities briefly described their respective long and short term
interests in Jordan Lake. The central question of the meeting was posed by Chatham County: "Is there
interest in OWASA working with Chatham County to develop an intake, even if Chatham needs it
earlier than OWASA would otherwise?"
The meeting participants agreed to discuss this question and related issues within their individual boazds
and reconvene as a large group during the first week in March 1999. A date and location have not yet
been specified (Attachment 1).
What are OWASA's long and short term interests in Jordan Lake?
Jordan Lake represents an important future raw water supply option for OWASA. Existing sources at
University Lake, Cane Creek, and the Stone Quarry Reservoir, as well as the potential benefit of an
expanded Stone .Quarry Reservoir, can not sustain the community's needs indefinitely. OWASA is
committed to maintaining a viable and reliable range of future options. More detailed information on the
extent and timing of future water needs is currently being developed through OWASA's Comprehensive
Water and Sewer Master Plan project. Preliminary water supply and demand data will be available by the
spring of 1999.

Discussion Paper -- Jordan Lake Options for OWASA
December 18, 1998
Page 2
What stake does OWASA already have in Jordan Lake?
Since 1988, OWASA has held a Level II (long term) allocation of 10 percent of Jordan Lake's water
supply storage capacity. This is expected to support an average withdrawal of 10 milliott gallons per day
(mgd). OWASA makes an annual payment of approximately $19,000 to the N.C. Department of
Environment and Natural Resources for this allocation. Additionally, OWASA owns 125 acres of land
adjacent to U.S. Army Corps of Engineers property on the western side of Jordan Lake, south of Highway
64 (Attachment 2). OWASA purchased 88 acres in 1989 and 37 acres in 1995 for a total cost of
$550,000. The Corps' amended Jordan Lake Master Plan designates an offshore intake site adjacent to
this azea, per recommendations of an engineering study conducted for OWASA in 1991 at a cost of
$35,000. It is important to note that no regulatory action has been taken to grant OWASA or any other
entity the right to use this site for water withdrawal purposes.
OWASA currently has a $60,000 contract with NCDOT to install a casement under U.S. 64 in the vicinity
of Mt. Gilead Church Road as part of the U.S. 64 improvement project. This will allow the installation of
a future water transmission line without the major expense of boring or tunneling under the highway.
Similar arrangements aze planned as NCDOT improves Highway 15-501.
What do we know about Jordan Lake's water quality?
Data available from the past 10 years indicate that water quality in Jordan Lake is good and neazly
indistinguishable in quality from other Triangle area water supply reservoirs, except in the northernmost
section upstream of S.R.1008, where it is highly enriched with nutrients.
Comprehensive watershed/water quality studies exist for other important reservoirs in the Triangle region,
but no such study has been conducted for Jordan Lake. Consequently, there is no credible technical basis
for estimating the water quality impacts of development projects or other activities proposed near Jordan
Lake or in the watershed. Since 1988, OWASA has participated in the Triangle Area Water Supply
Monitoring Program, which has several sampling sites in Jordan Lake and expects to contribute funds and
staff support to the Jordan Lake watershed study proposed by the Triangle J Council of Governments.
Additionally, OWASA plans to participate in special efforts to develop and calibrate a nutrient response
model in order to determine whether nitrogen removal is warranted at wastewater treatment plants
upstream of Jordan Lake.
What facilities would OWASA need to withdraw water from Jordan Lake?
Three basic systems would be needed to withdraw water from Jordan Lake and treat it at the OWASA's
Jones Ferry Road Water Treatment Plant (WTP) in Carrboro: (1) intake system, (2) two pumping
stations, and (3) a transmission pipeline.
Intake facilities would be located to provide water in sufficient quantities, even during low lake levels.
The intake must draw from multiple levels in the lake in order to obtain the highest quality water at any
given time.
Discussion Paper -- Jordan Lake Options for OWASA
December 18, 1998
Page 3
The intake structure could be located either onshore or offshore. An onshore structure would be served by
multiple underground pipes extending into the lake at different depths below the water surface
(Attachment 3). An offshore structure located in the lake would employ multiple intake gates at different
depths providing water back to shore through a single pipeline (Attachment 4). The preferred intake
configuration would be determined through additional engineering analysis.
A pumping station is needed to transport water from the intake system through approximately 15 miles of
transmission pipeline to OWASA's WTP. An additional booster pump station would be needed to
overcome friction losses and elevation changes between Jordan Lake and Carrboro. A potential pipeline
route is shown in Attachment 5.
How much will these facilities cost?
The cost figures provided are very preliminary and represent rough estimates only.
Facilities Cost Assumptions
Water Intake System $2.0 million 50 mgd intake structure with 1,000 feet of piping
Pumping Stations $5.9 million 50 mgd pumping station structure with 10 mgd
of installed capacity and a 10 mgd booster
pumping station
Transmission Pipeline $18.6 million 80,000 feet of 36 inch pipeline
Total $26.5 million
What options are available to OWASA and Chatham County for collaborating on the
withdrawal and transmission of water from Jordan Lake? What are their
advantages and disadvantages?
There appear to be five basic options available for collaboration, but substantially more engineering work
will be needed to identify and develop the list of possible options:
Do not collaborate on any facility development at this time, but allow OWASA's property
to be used by Chatham County or others.
2. Collaborate on a joint intake system only.
3. Collaborate on an intake system and make a portion of OWASA's Jordan
Lake property available for Chatham County to use in pumping raw water to its
own treatment plant.
4. Collaborate on an intake system and pumping station at the lake.
5. Collaborate on an intake system, pumping station at the lake, and portions of the
transmission pipeline.
Discussion Paper -- Jordan Lake Options for OWASA
December 18, 1998
Page 4
The U.S. Army Corps of Engineers and the N.C. Department of Environment and Natural Resources have
expressed the strong desire to have only one intake system located on the west side of Jordan Lake.
Limiting construction to one facility would minimize environmental and community disruptions and
provide substantial economies of scale.
The only known disadvantage to OWASA in proceeding with a joint intake system would be the
expenditure of capital funds in advance of OWASA's actual need for the facility. Depending on the scale,
cost, and financing method for project, it is possible that present value costs to OWASA should be lower
under this near term collaborative scenario than if OWASA deferred its investment to the future.
Cooperation on a joint pumping and transmission system would provide many of the same benefits noted
above, but because these facilities must be cazefully tailored to the specific needs of each user, they aze
less accurately estimated in advance than the more generic requirements for an intake system. OWASA
would incur significant additional expenses before such facilities were needed if it participated with
Chatham County in a joint project to provide pumping and transmission facilities in addition to an intake
system.
If OWASA and Chatham County cooperate on a joint intake system, OWASA believes that it could make
a portion of its Jordan Lake property available for Chatham County to use in pumping raw water to its
treatment plant.
What other utilities might share a cooperative interest in a regional intake system?
Orange County, Durham, and possibly Greensboro might have a future interest in Jordan Lake water.
Cary and Apex might be interested in supporting an intake structure on the western side of Jordan Lake
with sufficient capacity to supply their own needs during an emergency or shutdown of their existing
intake on the eastern side of the lake. These possibilities and others will be evaluated through OWASA's
Comprehensive Water and Sewer Master Plan Project now underway.
Are there any other collaborative opportunities to consider?
There can be substantial local and regional benefits if OWASA, Chatham County, and others participate
in a Jordan Lake watershed study. Other regional benefits beyond OWASA's purview might be
facilitated through OWASA's participation with Chatham County on an intake system.
As mentioned on previous occasions, it would be highly desirable to OWASA and its customers if the
zoning and development requirements in Chatham County's portion of the University Lake watershed
were consistent with rules in place in Orange County's and Carrboro's jurisdictions.
At some time in the future OWASA will require Chatham County's approval to construct the
infrastructure needed to transmit water from Jordan Lake to OWASA's facilities in Orange County.
Discussion Paper -- Jordan Lake Options for OWASA
December 18, 1998
Page 5
OWASA and Chatham County have agreed to establish an emergency only finished water interconnection
along U.S. 15-501 at the Orange County line. Chatham has already invested $120,000 to extend its 16-
inch pipeline to the OWASA system. This emergency only interconnection will provide long-term benefit
to both parties.
What is OWASA's recommendation?
OWASA believes there would be substantial environmental, technical, and economic benefits from
collaborating with Chatham County to develop a regional raw water intake system at Jordan Lake, even
though OWASA is not expected to need Jordan Lake water for at least ten years (this estimate is currently
being refined through OWASA's Comprehensive Water and Sewer Master Plan project). OWASA does
not propose participating in the joint development of pumping and transmission facilities from Jordan
Lake to OWASA at this time due to the high costs and relative absence of short term need. There may be
an opportunity to make a portion of OWASA's Jordan Lake property available for Chatham County to
use in pumping raw water to its own treatment plant. Additional engineering analysis is needed to more
fully evaluate these opportunities.
The OWASA Boazd of Directors believes that it is highly desirable that the March 1999 follow-up
meeting with local governments and the OWASA Boazd be scheduled as suggested during the October 1,
1998 Joint Meeting. Given the range of collaborative arrangements that presently exist or aze possible for
the future, it would be beneficial for all parties to establish and reinforce a strong constructive partnership
with Chatham County at the eazliest opportunity.
Whatever the outcome of future meetings of Chatham County officials with their counterparts from
Orange County, OWASA staff should maintain close communications with Chatham County engineering
personnel to monitor the development of the Chatham water supply and distribution system and to
identify opportunities for technical cooperation.

intake as a possibility and would like to use the OWASA intake location soon, if possible. We
are at maximum capacity some days now, we want to create a partnership around this regional
resource.
Carrboro_
We have no short-term water needs and may not have long-term needs. We are interested in
cooperating with Chatham County to meet emergency needs.
Orar:~e County
[nterested in maintaining high water quality and working with others to accomplish this. We
have maintained our allocation and are interested in protecting this allocation and making
efficient use of the intake.
OWASA
Long-term interest in maintaining 10 MGD allocation and access to the land we own at Jordan
Lake. We support the watershed study and are open to collaborating with neighboring utility
providers, subject to local policy goals. We are interested in maintaining water quality as well.
S?uestion Posed By Chatham County
• Is there interest in OWASA working with Chatham County to develop an intake, even if Chatham
needs it earlier than OWASA would otherwise?
Questions Raised By Participants
• What is the level of participation needed by the various governmental entities (e.g., amount of
capital required, short-term vs. long-term costs of developing intake at this time)?
• What is driving Chatham County's need (e.g., amount of development)?
• Under what conditions might Chatham share/use OWASA's intake location? What are the
options?
• Dces Chatham have an interest in working with Orange County governments to maintain a rural
buffer in southern Orange/northern Chatham area?
• Is Jordan Lake indeed considered a regional water supply? Is Chatham included in the region?
• Who should be involved in this discussion (i.e., governing boards' role vs. OWASA's role)?
• Can we develop a clear sense of each jurisdictions directinterests in Chatham's use of.focdan
lake?
• In the long term, wilt Orange County entities need to take water from Jordan Lake?
• What wilt OWASA's master plan indicate about its timing for the need of Jordan Lake's water?
• What forum should this issue come back to? Are participating entities willing to have a
conversation with their entice boards and then come back together to discuss?
• If Chatham County can act on its own, what is its incentive to cooperate on land use, etc.?
The Pariiciuatints Orange County Entities Agreed To Have A Conversation
With Their Entire Boards And Then Come Back Together To Discuss
Chatham-County's Use Of The OWASA Intake Site On Jordan Lake. TheX
Identified Several Pieces Of Information That They Needed Before Thy
Would Have This Board Discussion:
I. Information from OWASA on projected water use, options £x (and cost of) developing
intake site
2. Information from Chatham County regarding water needs
3. Exchange of land use plans and utility line plans between Orange and Chatham counties
4. Engineering information on the possibility of building an intake she that could be
expanded later
5. (Possibly) Chatham's estimate of the value of the property lost to Jordan Lake
Target date for boards to meet again to discuss interest in participating in cooperative dialogue with
Chatham County: first week in March 1999 (specific date to be determined)_
