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 April 1, 2001 through December 31, 2001 is included in Appendix
A. The water supply pools for each allocation holder were full on April 1, 2001.
For 2001, the maximum day withdrawal for all certificate holders was 18.8 mgd, which
occurred on July 20. The average daily withdrawal for all certificate holders was 9.7 mgd
during 2001 (Table 1-1). It should be noted that water withdrawals during 2001 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 9.7 mgd, the net finished
water delivered by the Cary/Apex WTP to the distribution system was 7.1 mgd in 2001.

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 2001,
finished water demands averaged 14.1 mgd and the maximum day demand was 22.0 mgd.
The maximum day peaking factor was 1.56 in 2001.

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 represents 24.5% of the water supply pool. Figure
1 shows the combined storage level for Cary, Apex, Morrsiville, and RTP South on a daily
basis from April 1 through December 31, 2001. The minimum storage level for the
combined allocation was 91%, occurring on several days in December 2001 when drought
conditions persisted in the region. The average percent storage was 98% from April
through December 2001.Individual Jordan Lake water allocations can be estimated on a
daily basis by estimating daily water usage for Morrisville and RTP South from monthly
records. Daily water use for Morrisville and RTP South is estimated from 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 monthly net
Cary water use is applied to monthly Morrisville and RTP South 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.

Total withdrawal for the Town of Morrisville is based on monthly billed water use (i.e. total
of retail sales to Morrisville customers). There is a discrepancy between billed water usage
obtained by Morrisville’s retail meters, and the water usage read by the Town of Cary at the
Morrisville master meters. Cary and Morrisville are investigating the discrepancy;
therefore, water usage for the Town of Morrisville should be considered preliminary until
Cary and Morrisville complete their investigation. Daily tracking of the water supply
storage allocation for the Town of Morrisville is shown in Figure 3. The Town of Morrisville
has 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 2001. The Town’s storage
level was nearly full during the period from April through December 2001 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,
2001 through Oct. 31, 2001. Therefore, total Jordan Lake withdrawals for RTP South were
zero from June to October 2001, 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 2001 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, 2001 through December 31, 2001. The maximum day IBT
transfer during the calendar year 2001 was 15. 0 mgd, which occurred on July 20, 2001. This
represents percent of the permitted IBT transfer under the certificate approved by the EMC
on July 12, 2001. The annual average IBT transfer was 6.8 mgd during calendar year 2001.
The average daily consumptive use was 15% for the period January 1, 2001 through
December 31, 2001 Historical consumptive use is shown in Table 2-1.
The distribution of consumptive uses between the Haw, Cape Fear, and Neuse River
subbasins for 2001 was based on historical water use in each basin as determined by billing
records for each certificate holder. For 2001, it was assumed that 14% of water use occurred
in the Haw subbasin, 0.6% of water use occurred in the Cape Fear subbasin 85.4% 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 in 2000 and 2001, based on billing records is shown in Table 2-2.

1. Includes some water use by Holly Springs. Holly Springs purchased water from Apex in 1998 and 1999.
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.
Table 2-3 shows the combined water use for each of the certificate holders and the
percentage water use in the Haw and Cape Fear River Subbasins.

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.

b = Peaking factor specified in Certificate for first year
d = Percent consumptive use specified in Certificate for first year
g = Average annual wastewater discharges and water reuse in Haw and Cape Fear Basins (see Table B-1)
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.
As shown in Section 2, the maximum day IBT for the certificate holders during 2001 was
only 65% of the permitted amount (24 mgd). Therefore, the IBT was not a limitation on
Jordan Lake withdrawals for each allocation holder.
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 2001.

P:\CARYAPEX_IBT-EIS\156003\2001 IBT ANNUAL REPORT_APP B_ FINAL.DOC 3--2
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 have submitted a Compliance and Monitoring Plan
concurrent with the submittal of this report.
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
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 are attached to this report as
Appendices C through F.
In 2001, the Town of Cary adopted a Water Shortage Response Plan in accordance with
Division of Water Resources guidelines in order to comply with the conditions of the IBT
2001 ANNUAL REPORT ON INTERBASIN TRANSFERS for RTP South and the Towns of Cary, Apex, and Morrisville
P:\CARYAPEX_IBT-EIS\156003\2001 IBT ANNUAL REPORT_APP B_ FINAL.DOC 3--3
certificate. This Water Shortage Response Plan expands on the Town’s existing water
conservation program as outlined in the Town’s Water Shortage Conservation Measures
Ordinance and the Alternate Day Irrigation Ordinance. The Town’s Water Shortage
Response Plan along with the Water Shortage Conservation Measures Ordinance is
included in Appendix C of this report.
In June 2000, the Town of Apex adopted a revised version of the February 1999 Water
Conservation Ordinance. The Ordinance outlines permanent conservation measures that
are required at all times. The Town of Apex has drafted a Water Shortage Response Plan,
and it is in the process of review and approval by the Town’s board. The Town’s draft
Water Shortage Response Plan and Water Conservation Ordinance is included in Appendix
D of this report.
The Town of Morrisville adopted a Water Shortage Conservation Ordinance in 1995 that
authorizes the Town Manager to adopt and enforce water conservation measures when a
water shortage from extended drought or emergency involving the Town’s treated water
supply or distribution system exists. In addition, Morrisville is required by contract terms
to implement any conservation measures adopted by Cary. In 2001, the Town of Morrisville
prepared a Water Shortage Response Plan and submitted it to DWR for review and
approval.
In 2001, RTP South prepared a Water Shortage Response Plan to comply with the conditions
of the IBT certificate and submitted it to DWR for review and approval. RTP South does not
own or operate a water system. Currently, RTP South purchases treated water from the
Town of Cary and relies on Cary to monitor utilization of their Jordan Lake water supply
allocation. A task force will be developed to include representatives from Wake County, the
Research Triangle Foundation, and the Town of Cary to determine when conservation
measures are needed to offset demands during drought conditions. The Water Shortage
Response Plan for RTP South is included in Appendix F of this 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 of the certificate holders has enacted stream buffer protection rules at least as
restrictive as the Neuse River buffer rules. In 2001, the Town of Cary enacted new stream
buffer rules in its Unified Development Ordinance. The buffer rules require a 100-ft riparian
buffer on all perennial and intermittent streams, lakes, and ponds. Chapter 14 of the Town’s
UDO covering Community Appearance and Environmental Protection Standards is
included in this report as Appendix G.
In October 2001, the Town of Apex adopted the changes to its Unified Development
Ordinance to include requirements for 50-ft stream buffers along intermittent streams and
100-ft buffers along perennial streams within the Town’s Extraterritorial Jurisdiction (ETJ). .
Modifications to the Town’s UDO (Section 6.1 Watershed Overlay Districts) is included in
Appendix H of this report.
2001 ANNUAL REPORT ON INTERBASIN TRANSFERS for RTP South and the Towns of Cary, Apex, and Morrisville
P:\CARYAPEX_IBT-EIS\156003\2001 IBT ANNUAL REPORT_APP B_ FINAL.DOC 3--4
In July 2001, the Town of Morrisville adopted changes to its Zoning Ordinance to include
provisions for a minimum 30-foot riparian buffer along all intermittent and perennial
streams in the Cape Fear Basin. In the Neuse River Basin, 50-ft stream buffers are required
per the Neuse River buffer rules enacted by the State Excerpts from the Town’s Zoning
Ordinance (Part C Development Standards and Requirements, Article II Miscellaneous
Standards Applicable in All Zoning Districts) is included in Appendix I of this report.
In July 2001, the Wake County Commissioners adopted a stormwater management program
to comply with State requirements (Neuse River Basin Model Stormwater Plan). Although
the State requirements apply only to the Neuse River Basin, Wake County adopted the same
rules for the Cape Fear Basin portion of the county as well. The County’s ordinance
requires 50-ft buffers along all intermittent and perennial streams. The rules apply to RTP
South. Also, the Research Triangle Foundation (RTF) has reserved permanent open space in
RTP South and requires a Surface Area Maintenance Easement, which restricts disturbance
of existing vegetation. Excerpts from the Wake County Stormwater Ordinance as well as a
copy of the Development Plan for RTP South are included as Appendix J.
