1.0 Jordan Lake Allocation Monitoring
The combined Jordan Lake water supply allocation for Cary, Apex, Morrisville, and RTP
South can be tracked on a daily basis. Daily tracking of the combined Jordan Lake
allocation for the period January 1, 2002 through December 31, 2002 is included in Appendix
A. The water supply pools for each allocation holder were full on January 1, 2002.
For 2002, the maximum day withdrawal for all certificate holders was 29.2 mgd, which
occurred on June 25. The average daily withdrawal for all certificate holders was 16.9 mgd
during 2002 (Table 1-1). It should be noted that water withdrawals during early 2002 were
unusually high due to construction at the Cary/Apex WTP and do not reflect potable water
demands by customers. While raw water withdrawals averaged 16.9 mgd, the net finished
water delivered by the Cary/Apex WTP to the distribution system was 14.2 mgd in 2002.

Table 1-2 presents historical water use for the certificate holders (Cary, Apex, Morrisville,
and RTP South) based on finished water produced at the Cary/Apex WTP. In 2002,
finished water demands averaged 14.9 mgd and the maximum day demand was 25.6 mgd.
The maximum day peaking factor was 1.72 in 2002.

Water use for Morrisville and RTP South is not measured on a daily basis. Therefore,
accurate daily tracking of Jordan Lake water supply allocations can only be performed for
the combined Jordan Lake water supply allocation for Cary, Apex, Morrsiville, and RTP
South. Their combined Level I allocation was increased from 24.5% of the water supply to
39% of the water supply pool on July 12, 2002. Figure 1 shows the combined storage level
for Cary, Apex, Morrsiville, and RTP South on a daily basis from January 1 through
December 31, 2002. The minimum storage level for the combined allocation was 91%,
occurring on several days in December 2002 when drought conditions persisted in the
region. The average percent storage was 98% from April through December 2002.
Individual Jordan Lake water allocations are estimated on a daily basis by estimating daily
water usage for Morrisville and RTP South from monthly records. Daily water use for
Morrisville is estimated from monthly or more frequent retail meter readings by assuming
that water usage variations between meter readings follow the same patterns as the total
combined water use (“Net Cary” use). Daily water use for RTP South is estimated similarly
using monthly retail meter readings. by assuming that water usage trends throughout the
month follow similar patterns as for Cary. For a given day, the ratio of daily Net Cary water
use to average net Cary water use for the period between meter readings is applied to
Morrisville and RTP South metered water use. Levels in individual water supply pools are
calculated on a daily basis using daily water use estimates and daily lake inflows. Lake
inflow data is obtained from the US Army Corps of Engineers and allocated to each water
supply pool according to the percentage allocation held. Any inflow amount that would fill
the allocated storage above 100 percent is not stored. Any time the elevation in Jordan Lake
is at or above 216 feet mean sea level, the water supply pools are reset to 100 percent full.
Daily tracking of the Cary/Apex water supply storage allocation is shown in Figure 2. The
daily withdrawal amounts are estimated by subtracting the estimated daily Morrisville and

RTP amounts from the metered total daily use. Cary/Apex holds a water supply storage
allocation equal to 32 percent of the water supply pool or 9,618 acre-feet. The minimum
storage level for Cary/Apex was 88%, occurring in December 2002. The average percent
storage was 97.5% from April through December 2002.
Daily tracking of the water supply storage allocation for the Town of Morrisville is shown in
Figure 3. The Town of Morrisville had a bulk purchase contract with the City of Durham for
up to 1.2 mgd of finished water through May 2002. Therefore, purchases from the City of
Durham reduced the amount of water needed from the Town’s water supply storage pool
during early 2002. The Town’s storage level was nearly full during the period from April
through December 2002 with a minimum level of 98% occurring in December.

RTP South purchased up to 0.5 mgd of finished water from the City of Raleigh from June 20,
2002 through Oct. 31, 2002. Therefore, total Jordan Lake withdrawals for RTP South were
zero from June to October 2002, with the exception of two days where demands peaked
above 0.5 mgd. Daily tracking of the storage level for the RTP South water supply storage
allocation is shown in Figure 4. The RTP South water supply pool remained nearly full
during April through December 2002 with a minimum of 98% occurring in December.

2.0 IBT Monitoring
Daily IBT estimates for the certificate holders are included in Appendix B. Estimates are
provided for the period January 1, 2002 through December 31, 2002. The maximum day IBT
transfer during the calendar year 2002 was 22.5 mgd, which occurred on June 25, 2002. This
represents 93.7 percent of the permitted IBT transfer under the certificate approved by the
EMC on July 12, 2001. The annual average IBT transfer was 13.5 mgd during calendar year
2002.
The average daily consumptive use was 20% for the period January 1, 2002 through
December 31, 2002. Historical consumptive use is shown in Table 2-1.
The distribution of consumptive uses between the Haw, Cape Fear, and Neuse River
subbasins for 2002 was based on historical water use in each basin as determined by billing
records for each certificate holder. For 2002, it was assumed that 14% of water use occurred
in the Haw subbasin, 0.6% of water use occurred in the Cape Fear subbasin, and 85.4% of
water use occurred in the Neuse River subbasin. The certificate holders have begun
tracking historical use by assigning a subbasin to each customer. Data on the distribution of
water use between subbasins for each entity from 2000 through 2002, based on billing
records, is shown in Table 2-2.
In 1998, 1999, and 2000 Apex and Cary implemented mandatory irrigation restrictions due
to water supply limitations and IBT permit restrictions. The Town of Morrisville asked
residents to voluntarily conserve water beginning in 1998, and implemented mandatory
water use restrictions in July 1999. The restrictions reduced consumptive water use from
what would normally be expected during those years. In 2002 all the Towns had mandatory
restrictions because of regional drought conditions, but they were implemented after June,
which was when all-time high water use occurred. Appendix C summarizes the 2002 water
use restrictions.

1. Water use by subbasin for the Town of Morrisville is unavailable for 2000, and so was assumed to be the same as in 2001.

For purposes of calculating daily IBT amounts in 2002, the certificate holders used 19% for
the portion of their water use that occurred in the Haw subbasin and 0.6% as the portion
used in the Cape Fear subbasin. For purposes of calculating daily IBT amounts in 2003, the
certificate holders estimate that 23% of their water use will occur in the Haw subbasin and
that 0.6% of their water use will occur in the Cape Fear subbasin.

3.0 Compliance with Certificate Conditions
A summary of the conditions of the IBT certificate dated July 12, 2001 along with the current
status of compliance for each is provided below.
Condition 1 (2010 Required Return)
The holders of the certificate, after 2010, shall return water supplied from the Haw River Basin used
in the Neuse River Basin to either the Haw or Cape Fear River Basins as described below.
a) Any water use in the Neuse Basin in excess of 16 million gallons per day adjusted on an
average daily basis shall be returned.
b) Water used for consumptive purposes in the Neuse Basin will not be subject to this condition
Compliance with this condition is not required until after 2010. However, the calculations
for determining compliance with Condition 1 are shown in Table 3-1. Note that revised
calculations for 2001 result in different values then were included in the 2001 Annual
Report.
Wake County, Cary, Apex and Morrisville are participating in the Western Wake County
Regional Wastewater Treatment Study along with Holly Springs and Fuquay-Varina. The
partners expect to select an alternative for implementation in the summer of 2004. More
information about the status of the study can be found on Cary’s website at
http://www.townofcary.org/depts/pwdept/capefear/index.htm.

Condition 2 (Facilitate Allocation Use)
The holders of this certificate shall manage the authorized transfer amount in such a way that none of
the individual petitioners (Towns of Cary, Apex, Morrisville, and Wake County [for RTP South]) are
prevented from fully using their respective Jordan Lake water supply allocations.
The IBT was not a limitation on Jordan Lake withdrawals for any of the allocation holders in
2002.

3--2
Condition 3 (Disagreggation of IBT Amount)
If the certificate holders discontinue their cooperative service agreement with each other, the
maximum day permitted transfer will be adjusted by the Division of Water Resources based on the
2030 projected of each applicant at that time.
The cooperative service agreements between the certificate holders have remained in effect
during 2002.
Condition 4 (Compliance and Monitoring Plan)
Prior to transferring water under this certificate, the holders of this certificate shall work with the
Division of Water Resources to develop compliance and monitoring plan subject to approval by the
Division. The plan shall include methodologies and reporting schedules for reporting the following
information: maximum day transfer amounts, compliance with permit conditions, progress on
mitigation measures, drought management, and reporting. A copy of the approved plan will be kept
on file with the Division for public inspection. The Division of Water Resources shall have the
authority to make modifications to the compliance and monitoring plan as necessary to assess
compliance with the certificate.
Cary, Apex, Morrisville, and RTP South submitted a Compliance and Monitoring Plan
concurrent with the submittal of the 2001 report. The certificate holders request to modify
the Compliance and Monitoring Plan such that the annual reports are due by May 1 of the
following year.
Condition 5 (EMC Consideration of Impacts)
If either the EIS is found at a later date to be incorrect or new information becomes available such that
the environmental impacts associated with this transfer are substantially different from those
projected impacts that formed the basis for the above Findings of Fact and this certificate, the
Commission may reopen the certificate to adjust the existing conditions or require new conditions to
ensure that the detriments continue to be mitigated to a reasonable degree.
This condition requires no action by the certificate holders.
Condition 6 (Intake Access)
The Towns of Cary and Apex shall be required to provide access at their existing intake site to other
Jordan Lake water allocation holders that need access to utilize their allocation to the extent that this
additional use is determined to be feasible by the Division of Water Resources. The cost associated
with getting the necessary permits, engineering design, and associated construction costs are the
responsibility of the allocation holder(s) requesting the access and not Cary and Apex.
The Town of Cary has continued to provide retail water service to RTP South and has a bulk
purchase agreement with the Town of Morrisville. The Towns of Cary and Apex have also
entered into an agreement to allow Chatham County access to the Cary/Apex raw water
intake on Jordan Lake.
Condition 7 (Drought Management Plan)
Prior to transferring water under this certificate, the Towns of Cary, Apex, and Morrisville, and
Wake County (for RTP South) shall develop individual water shortage response plans subject to
approval by the Division. The holders of this certificate shall develop a drought management plan for
the interbasin transfer, incorporating the individual water shortage response plans and subject to
2002 ANNUAL REPORT ON INTERBASIN TRANSFERS for RTP South and the Towns of Cary, Apex, and Morrisville
3--3
approval by the Division. The plans shall tie specific water conservation actions to the percent
storage remaining in each of the petitioners’ Jordan Lake water supply accounts. A copy of the
approved plans shall be kept on file with the Division for public inspection. The Division of Water
Resources shall have the authority to approve modifications to the drought management plan as
necessary.
Water Shortage Response Plans for each certificate holder were submitted as attachments to
the 2001 Annual Report.
Condition 8 (Stream Buffer Rules)
Within six months from the effective date of this certificate, the Towns of Cary, Apex, and
Morrisville, and Wake County (for RTP South) shall enact ordinances similar to or more protective
than the Neuse River buffer rules (15A NCAC 2B.0233) for the parts of their jurisdictions that are
within the Jordan Lake watershed. These buffer requirements shall be subject to approval by the
Division of Water Resources after consultation with the Division of Water Quality and shall be
adopted as local ordinances.
Each Town’s buffer ordinance was submitted with the 2001 Annual Report. There were no
changes in 2002.
