Subject: IBT Report for 2007
Dear Tom:
We are sending our calendar year 2007 IBT Annual Report. We are also transmitting this
report to you electronically. The report follows the format of earlier reports and includes
a narrative section with background and program progress reports along with
spreadsheets detailing the IBT amount calculation.
For calendar year 2007, we experienced an actual maximum day IBT of 17.22 mgd based
on September billing data and as of December 31, 2007, had additional outstanding IBT
commitments of 3.56 mgd. The summation of these amounts would indicate a 2007 IBT
amount of 20.78 mgd which is less than 63% of our authorized amount.
Please let me know if you have any questions.
Sincerely,
CHARLOTTE-MECKLENBURG UTILITIES

Charlotte-Mecklenburg Utilities
Annual Report on Interbasin Transfer
Calendar Year 2007
Charlotte Mecklenburg Utilities (Utilities) operates the water and wastewater systems that serve
Charlotte, Cornelius, Davidson, Huntersville, Mint Hill, Matthews, Pineville, and much of the
unincorporated areas of Mecklenburg County. This system is divided between two river basins
designated by NC General Statutes for regulation of interbasin transfer (IBT) of water. The
western portion of the system is within the Catawba River basin and the eastern portion is within
the Rocky River basin. Water transferred from the Catawba River basin to the Rocky River basin
that is not returned to the Catawba is regulated IBT.
The North Carolina Environmental Management Commission (EMC) approved Charlotte
Mecklenburg Utilities’ petition to increase the amount of water transferred from the Catawba
basin to the Rocky River basin and an IBT Certificate was issued on March 14, 2002. The
Certificate authorizes Utilities to transfer up to 33 million gallons per day (mgd) from the
Catawba River basin to the Rocky River basin.
Water for distribution to Utilities’ customers is withdrawn from the Catawba River basin at two
locations. An intake at Lake Norman sends water to the Lee S. Dukes Water Treatment Plant. A
second intake at Mountain Island Lake sends water to the Walter M. Franklin Water Treatment
Plant and to the Vest Water Treatment Plant. Potable water from these three plants is delivered
through an interconnected distribution system to retail customers throughout Utilities’ service
area in Mecklenburg County, in small areas of Iredell, Cabarrus, and Union Counties, and to
other municipal systems including York County, S.C. Lancaster County (S.C.)Water and Sewer
District, and Union County.
Utilities treats wastewater at five advanced wastewater treatment plants (WWTP’s) which
discharge into small streams in Mecklenburg County. Four of the streams are tributary to the
Catawba River basin and one (Mallard Creek) is tributary to the Rocky River basin. Utilities also
conveys wastewater generated in portions of Mecklenburg to the Rocky River Regional
Wastewater Treatment Plant (RRRWWTP) operated by the Water and Sewer Authority of
Cabarrus County (WSACC). The RRRWWTP discharges treated effluent to the Rocky River.
Utilities can transfer treated potable water to the City of Concord through three metered
connections to their water system. All of Concord’s service area is within the Rocky River
basin, so any water purchased by them becomes an IBT. Water service is only provided as an
emergency back-up to Concord’s routine supply which is Lake Howell and several smaller
reservoirs. All of these reservoirs are within the Rocky River basin. Wastewater from Concord
is treated at the RRRWWTP. Utilities’ agreement with Concord is that water will be supplied to
them subject to availability and subject to regulatory constraints including IBT and Federal
Energy Regulatory Commission (FERC) limitations.

Concord received an IBT Certificate in January 2007, for the transfer of up to 10 mgd from the
Catawba River basin to the Rocky River basin. NC DWR advised Utilities that water sold to
Concord should not be applied to Utilities’ IBT amount. Concord did not purchase any potable
water from Utilities in calendar year 2007, so the IBT amounts reported do not include sales to
Concord.
The IBT Certificate requires Utilities to report maximum daily IBT amounts annually to the
North Carolina Division of Water Resources until such time as the transfer amount exceeds 80%
of the authorized amount. Once that amount is exceeded, Utilities is required to report monthly.
To date, Charlotte-Mecklenburg Utilities has not exceeded 80% of the authorized IBT amount.
Table 1 below summarizes actual IBT amounts for calendar years 2002 through 2007 (all
calculated using the new methodology approved by N.C. DWR in June of 2006). The table
considers the daily amounts of water transferred from the Catawba basin to customers within the
Rocky River basin that is not returned to the Catawba basin.
The data indicates that the maximum amount of IBT for year 2007 occurred in September, and
was 17.22 mgd, or 52% of the authorized maximum day value of 33 mgd. The average IBT for
2007 was 9.96 mgd, which is about 30% of the authorized maximum day value. In addition to
the amount of actual IBT reported in Table 1, Utilities has committed to provide additional IBT
to development that has been proposed but not yet activated in the Rocky River basin. As of
December 31, 2007, 1.39 mgd was committed to permitted donated projects (subdivisions) that
had not been activated and 2.17 mgd was committed to master meter connections (generally
commercial or multi-family developments) that had not been activated, both based on maximum
day estimates. This brings the total of the actual and outstanding IBT in 2007 to 20.78 mgd, or
63% of the authorized maximum day value.

Condition 1 of Utilities’ IBT certificate requires Mecklenburg County to summarize progress in
implementation of watershed management approaches of the Surface Water Improvement and
Management Program (S.W.I.M. program). This summary follows:
The watershed management approaches of the Surface Water Improvement and
Management (SWIM) Program continued to be implemented during calendar year 2007.

Efforts focused on McDowell Creek in the north and Goose Creek in the south, which were
the 2 watersheds identified for restoration as a result of the prioritization completed for the
22 watersheds in Mecklenburg County during 2006. McDowell Creek drains to Mountain
Island Lake, which is the primary drinking water supply for Charlotte-Mecklenburg.
Significant land development in this watershed has resulted in an increase in non-point
source pollutant loads. Therefore, this watershed has been assigned a high priority for
restoration. Goose Creek is home to a federally listed endangered species of freshwater
mussel called the Carolina Heelsplitter. The primary threat to the survival of the
Heelsplitter is storm water runoff from land development activities; therefore, this
watershed has been given a high priority for restoration.
During calendar year 2007, the following work was completed in the McDowell Creek
watershed:
1. Continued to update and refine the McDowell Creek Watershed Management Plan for
the purpose of restoring degraded water quality conditions.
2. Grant application for $750,000 submitted to the N.C. Clean Water Management Trust
Fund for a planned stream restoration project in the McDowell Creek Watershed in an
area that is ranked as a high priority in the Watershed Management Plan. Mecklenburg
County will provide $2,550,000 toward this project, which will include the construction
of a greenway along the creek. The total project cost is $3,300,000.
3. Mecklenburg County partnered with the Sierra Club and over 100 volunteers to plant
900 trees along the banks of McDowell Creek over approximately 3 acres. This area
was targeted in the Watershed Management Plan as a high priority for restoration of the
buffer corridor.
4. Mecklenburg County established a partnership with the Town of Cornelius to conduct
two stream restoration projects in the Town’s jurisdiction in the headwaters of
McDowell Creek. These stream sections are among the most highly degraded in the
watershed and have the highest priority for restoration in the Watershed Management
Plan. Preliminary designs for the stream restoration projects are underway.
5. During 2007, design work was completed for the installation of 10 rain gardens into a
60 acre parking lot in the Northcross Shopping Center in Huntersville, which is located
in the headwaters of McDowell Creek in a high priority area for the generation of non-
point source pollutants. The project was completed in May 2008. In addition to the
Northcross Shopping Center project, Mecklenburg County partnered with other private
businesses in Huntersville to add a total of 16 rain gardens and wetlands at Carolinas
Medical Center-Northcross, Northcross Commons, NorthPointe Executive Business
Park, and in the Monteith Park residential subdivision. Known as the McDowell Best
Management Practices project, the five sites are all located in the same general location
in the headwaters of McDowell Creek. The cost of building the rain gardens and
Page 5 of 6
wetlands at the five locations was $1.9 million dollars. Nearly $800,000 of this money
came from Storm Water fees paid by Mecklenburg County residents. The remaining $1.1
million was funded through grants from the North Carolina Clean Water Management
Trust Fund and North Carolina Division of Environment and Natural Resources. Land
was donated by American Asset Corporation, Carolinas HealthCare Systems,
Northcross Properties LLC, NorthPointe Realty Corporation, Saussy Burbank, and
Sentinel Real Estate Corporation, thanks to partnerships with Harris Teeter, Kohl's, and
Lowe's. This is the first of many very large projects planned in the McDowell Creek
Watershed.
6. Mecklenburg County is in the planning process for a partnership with the Sierra Club
for a Water Quality Summit to be held in 2008 in the headwaters of the McDowell Creek
Watershed. The summit will target residents in the area and will focus on buffer
plantings, stream cleanups and other activities for restoring water quality conditions in
McDowell Creek through the implementation of the Watershed Management Plan.
During calendar year 2007, the following work was completed in the Goose Creek
watershed:
1. Extensive water quality monitoring was completed and a Water Quality Recovery
Program for reducing fecal coliform bacteria levels was developed based off the results
of this monitoring. This Water Quality Recovery Program is being rolled into a more
comprehensive Watershed Management Plan that focuses on restoring overall water
quality conditions in the creek.
Condition 2 of Utilities’ IBT certificate requires a report on the stakeholder process to investigate
water quantity control from single-family development and water quality control for all
development until that process is completed. The condition suggests that the feasibility of single-
family detention should be considered along with any needed ordinance revisions. This report
follows:
In June 2007, post-construction storm water ordinances went into effect in Mecklenburg
County and the Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill and
Pineville. Extensive effort went into training staff and the development community
regarding the actions necessary to ensure compliance with these ordinances. In addition,
an Administrative Manual, a BMP Design Manual and website were developed to assist in
compliance. The ordinances were adopted by the jurisdictions following the completion of a
stakeholders’ process that ran from April 2004 through September 2005. The ordinances
include a requirement to remove 85% Total Suspended Solids from the first inch of runoff
for commercial and residential projects, and an additional 70% Total Phosphorus removal
from the first inch of runoff if the project is located in either the Yadkin or Upper Catawba
USGS 8-digit hydrologic unit code watersheds. Water quantity elements include controlling
Page 6 of 6
the entire post development volume generated by the 1-year 24-hour storm and releasing
between 48 and 120 hours, for both residential and commercial developments. In addition
all projects must provide peak control for the 10-year 6-hour and 25-year 6-hour storm
events, although peak control may be waived for certain projects if a downstream analysis
shows no adverse impacts from the development. Implementation of the ordinances has
gone very well since their adoption.
The adoption and implementation of the post-construction storm water ordinances concludes the
processes described in Condition 2. Future annual IBT reports will refer to Condition 2 as
having been completed in 2007.
Condition 3 of the IBT Certificate removes the Goose Creek subbasin from the area to be served
by the IBT, and imposes a moratorium on the installation of new IBT water lines (water lines
crossing the ridgeline) into Goose Creek subbasin until the impacts of additional growth on the
endangered species are fully evaluated. In 2005, the Southern Environmental Law Center
(SELC) requested a Declaratory Ruling from the N.C. Environmental Management Commission
relative to Utilities' compliance with this condition. While the EMC declined to issue a
Declaratory Ruling, it did direct DWR staff to develop recommendations about IBT
measurement and interpretation of Condition 3. Staff’s response (issued June 29, 2006)
concluded that Utilities has complied with Condition 3, but confirmed NC DWR’s January 20,
2006, direction to Utilities to impose a moratorium on new water services in the Goose Creek
subbasin when total IBT allocations (actual plus committed) to the Rocky River basin reached
the grandfathered amount. Utilities suspended acceptance of applications for new water services
in the Goose Creek subbasin until the committed IBT amount could be determined.
In 2006 and 2007, after the committed IBT amount was determined, interested third parties in the
Goose Creek basin requested that NC DWR reconsider the interpretation of the new water
services moratorium. The request was for NC DWR to allow the portion of the grandfathered
IBT amount that was unused and uncommitted at the time the moratorium was imposed to be
used within the Goose Creek basin. NC DWR agreed to the request. As a result, a relatively
small amount of water was made available in the Goose Creek basin. With concurrence from
NC DWR, Utilities used previous requests to allow proposed developments access to this water
in the order the requests had been received.
Regarding resolution of the impacts of additional growth on the endangered species, NC
Division of Water Quality (DWQ) has proposed a site specific management plan for the Goose
Creek basin. The plan proposes to use buffers and other techniques to protect the endangered
species from the impacts of growth. It is anticipated that the site specific plan will be approved
by the NC EMC in 2008. In anticipation that Mint Hill’s adoption of a post construction
stormwater control ordinance and DWQ’s proposed site specific management plan would resolve
the issues related to this condition, NC DWR informed the NC EMC on September 12, 2007,
that DWR planned to develop an environmental assessment (EA) document to provide a basis for
the EMC to consider a modification of condition 3 of Utilities’ IBT Certificate. Utilities and
DWR staff developed a plan for how the EA would be developed and processed. As of
December 31, 2007, Utilities was preparing to initiate development of the EA according to that
Page 7 of 6
plan.As of December 31, 2007, the moratorium on installation of new water mains into theGoose
Creek subbasin remained in place.
Condition 4 of the IBT Certificate provides that the Environmental Management Commission
may reopen the Certificate under certain circumstances. This did not occur in 2007.
Condition 5 of the IBT Certificate requires Utilities to develop a compliance and monitoring plan
for reporting maximum daily transfer amounts, compliance with certificate conditions, progress
on mitigation measures, and drought management activities. Utilities’ monitoring plan and
reporting format were approved in June of 2006 by NCDWR and continued to be used for 2007.
Due to below average rainfall and above average temperatures, weather conditions in 2007
required the implementation of drought management activities. Based on triggers established in
the Low Inflow Protocol (LIP) document adopted by the members of the Catawba-Wateree
Drought Management Advisory Group, Utilities (along with other water users required to
comply with the LIP) followed water conservation measures outlined in the LIP document. In
early August 2007, Utilities’ water customers were asked to voluntarily reduce their water
consumption. After several additional weeks with minimal rainfall and above average water
consumption, on August 28th the Catawba-Wateree River Basin went into mandatory water
restrictions under Stage 2 of the LIP (limiting outdoor water use to 2 days per week). Following
another month of hot, dry days, Charlotte-Mecklenburg customers entered into Stage 3 water
restrictions on September 26, 2007, (restricting almost all outdoor water use); Stage 3
restrictions continued to be enforced throughout the rest of 2007. Recent calculations show that
these water conservation measures were successful in reducing water consumption; residential
customers reduced their water use more than 30 percent as compared to their average
unrestricted use spanning 2000-2006.
In summary, Utilities is in full compliance with IBT authorizations and compliance conditions.
The amount of water transferred from the Catawba River basin to the Rocky River basin in 2007
is significantly less than the authorized amount.
