2003 IBT Annual Report

Charlotte Mecklenburg Utilities
Interbasin Transfer
2003 Annual Report

Charlotte Mecklenburg Utilities (Utilities) operates the water and wastewater system that
serves the City of Charlotte, Davidson, Huntersville, Mint Hill, Matthews, Pineville, and
much of the unincorporated areas of Mecklenburg County. This utility system, covering
most of Mecklenburg County, is divided between two drainage basins as designated by
NC General Statutes. The western portions of the system are within the Catawba River
basin and the eastern portion is within the Rocky River basin. Water that is transferred
from the Catawba River basin to the Rocky River basin that is not returned to the
Catawba is defined as interbasin transfer (IBT).

Water is withdrawn from the Catawba River basin at two locations. An intake at Lake
Norman sends water to the North Mecklenburg Water Treatment Plant. A second intake
at Mountain Island Lake sends water to the Franklin Water Treatment Plant and the Vest
Water Treatment Plant. Potable water from these three plants is delivered through an
interconnected distribution system to customers throughout Mecklenburg 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 sends wastewater from several 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 in the Rocky
River.

Utilities transfers treated, potable water to the City of Concord through several metered
connections with their water system. Water is transferred as an emergency back-up to
Concord’s routine supply which comes from Lake Howell and several smaller reservoirs.
All of these reservoirs are within the Rocky River basin. Wastewater from Concord is
treated at the RRRWWTP.

Charlotte Mecklenburg Utilities’ petition to increase the amount of water transferred
from the Catawba basin to the Rocky River basin was approved by the North Carolina
Environmental Management Commission (EMC) on March 14, 2002. The petition
allows Utilities to transfer up to 33 million gallons per day (mgd).

The approved petition requires Utilities to report 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, which would be 26.4 mgd. Once that amount is
exceeded, Utilities is required to report monthly.

Table 1 below summarizes 2003 daily IBT amounts. The table considers the daily
amounts of water delivered from the Catawba basin to customers within Mecklenburg
County based on combined pumping records from the three water treatment plants. The
values shown in Table 1 include the amount of water transferred to the City of Concord
through metered connections. Transfers to Concord are included as average daily values
over the billing period which is approximately monthly. The full amount transferred to
Concord is IBT since none is returned from Concord to the Catawba basin. Daily
wastewater treatment plant discharges are used to determine how much flow is returned
to the Catawba basin and how much is discharged directly to the Rocky River basin from
Utilities’ Mallard Creek WWTP. Wastewater flows sent to RRRWWTP (and thereby
discharging into the Rocky River basin) are included in Table 1 as average daily flows
based on wastewater flow meter readings which are made approximately monthly.
Consumptive use within the Rocky River basin is considered IBT according to North
Carolina statutes. Consumptive use occurs due to septic tank systems, lawn irrigation,
inclusion of water in packaged products, evaporation, and other uses. The amount of this
consumptive use is estimated based on criteria described in Utilities’ IBT petition.

Combination of the data allows the calculation of the daily IBT amount. Table 1 presents
these amounts both as a percentage of the authorized amount and as a daily transfer
amount in mgd. The data is also presented in two charts which depict graphically the
IBT amounts.

The data indicates that the maximum amount of IBT for year 2003 occurred on
September 20, 2003, and was 15.92 mgd, or 48% of the authorized maximum day value
of 33 mgd. The average IBT for 2003 was 12.18 mgd, which is about 37 % of the
authorized maximum day value.

A special condition in the EMC’s decision granting Utilities’ IBT petition 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). Mecklenburg County Water Quality Program’s report on this
condition is below:

Basic countywide water quality modeling capabilities have been developed and
are being upgraded to include advanced modeling capabilities for planning/land
development. A fully functioning water quality model has been developed for
McDowell Creek in the Town of Huntersville where rapidly degrading water
quality conditions have been experienced due to growth within the watershed.
Outputs from the McDowell model were used to develop a watershed based
approach for identifying alternative management strategies targeted toward
preventing further water quality degradation. As a result of this effort, a
performance based land development ordinance was developed that relies on Low
Impact Design (LID) strategies to protect water quality from future development
activities, which was adopted by the Town of Huntersville on February 17, 2003.
Water quality modeling and watershed based planning initiatives are also being
used in the design of two (2) large mixed use developments along Lake Wylie to
protect water quality from land development activities. Efforts are currently
underway to expand this watershed based management approach to other areas
of the county, with the highest priority being the Goose Creek basin in Mint Hill.

A second special condition 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. Mecklenburg County’s Water Quality Program reports:

The water quality ordinance developed for the Town of Huntersville provides water
quality controls for single-family development as well as establishes requirements for
single-family detention. The McDowell model clearly demonstrated that significant
negative water quality impacts result from increased storm water flows associated
with development in the watershed and increased impervious surface cover. The
model established that addressing overland nonpoint source pollutants was not
adequate to protect water quality but that measures were also needed to address
these increased flows. As a result, the Huntersville Ordinance was designed to
address both water quality and detention. This is the first time in Mecklenburg
County that the quality and quantity of storm water runoff has been addressed in a
comprehensive manner. The objective is to use a similar approach in the other
Towns as we expand our watershed based management efforts. The basic objectives
of the Huntersville Ordinance are listed below.

¾ Minimize increases in storm water runoff from development or redevelopment in
order to reduce flooding, siltation and streambank erosion, and maintain the
integrity of stream channels.

¾ Utilize Low Impact Design (LID) strategies to minimize increases in non-point
source pollution caused by storm water runoff from development or
redevelopment. The goal of LID is to develop site design techniques, strategies,
and BMPs to store, infiltrate, evaporate, retain, and detain runoff on the site to
more closely replicate pre-development runoff characteristics and to better mimic
the natural and unique hydrology of the site thereby limiting the increase in
pollutant loads caused by development.

¾ Minimize the total volume of surface water runoff that flows from any specific site
during and following development in order to replicate pre-development
hydrology to the maximum extent practicable.

¾ Reduce storm water runoff rates and volumes, soil erosion and non-point source
pollution, to the extent practicable, through storm water management controls
(BMPs) and to ensure that these management controls are properly maintained
and pose no threat to public health or safety.

The performance criteria contained in the Huntersville Ordinance are provided
below.

¾ All storm water treatment systems used to meet these Performance Criteria shall
be designed to achieve average annual 85% Total Suspended Solids (TSS)
removal for the developed area of a site. Areas designated as open space that are
not developed do not require storm water treatment. All sites must employ LID
practices to control and treat runoff from the first inch of rainfall.

¾ LID practices or a combination of LID and conventional storm water
management practices shall be used to control and treat the increase in storm
water runoff volume associated with post-construction conditions as compared
with pre-construction (existing) conditions for the 2-year frequency, 24-hour
duration storm event in the Rural and Transitional Zoning Districts. For all
other Zoning Districts, LID practices or a combination of LID and conventional
storm water management practices shall be used to control and treat the increase
in storm water runoff volume associated with post-construction conditions as
compared with pre-construction (existing) conditions for the 1-year frequency,
24-hour duration storm event. This may be achieved by hydrologic abstraction,
recycling and/or reuse, or other accepted management practice as described in
Section 6 of the Huntersville Water Quality Design Manual.

¾ Where any storm water BMP employs the use of a temporary water quality
storage pool as a part of its treatment system, the drawdown time shall be a
minimum of 48 hours and a maximum of 120 hours.

¾ Peak storm water runoff rates shall be controlled for all development above 12%
imperviousness. The peak storm water runoff release rates leaving the site during
post-construction conditions shall be equal to or less than the pre-development
peak storm water runoff release rates for the 2-year frequency, 24-hour duration
storm event and 10-year frequency, 24-hour duration storm event. The
emergency overflow and outlet works for any pond or wetland constructed as a
storm water BMP shall be capable of safely passing a discharge with a minimum
recurrence frequency of 50 years. For detention basins, the temporary storage
capacity shall be restored within 72 hours. Requirements of the Dam Safety Act
shall be met when applicable.

¾ No one BMP shall receive runoff from an area greater than five (5) acres.
However, the total drainage area from BMP’s used in series (i.e., integrated) can
exceed this five (5) acre maximum.

A third special condition in the EMC’s decision imposes a moratorium on the installation
of new IBT water lines into Goose Creek subbasin. This moratorium remains in place.

The EMC’s decision also requires Utilities to report on drought management activities.
The summer of 2002 brought extreme drought conditions to much of North Carolina,
including Utilities’ service area. Utilities imposed mandatory water conservation
measures for a ten-week period between August 21 and October 31, 2002. During this
period, customers were prohibited from watering lawns between 4:00 a.m. and 9:00 p.m.
Coupled with an aggressive enforcement effort, the program resulted in significant
reductions in water demand. Utilities’ evaluated the information gathered in 2002 has
developed water conservation ordinance revisions that will enhance Utilities’ ability to
respond to water shortages by imposing varying degrees of usage restrictions and to
enforce ordinance provisions. The revised ordinance was approved by Charlotte City
Council on March 24, 2003.
