Subject: Notification of Jordan Lake Nutrient Requirements
NPDES Permit NCO055271
Shields Mobile Home Park
Alamance County
Governor Bev Perdue recently signed legislation to complete passage of rules for the Jordan Lake
Nutrient Management Strategy. The Strategy includes a Wastewater Discharge rule (T15A NCAC 02B
.0270) that applies to your wastewater treatment facility. Pursuant to Sub -Item (6)(d) of the rule, I am
writing to notify you of the nutrient allocations assigned to your facility.
This letter addresses only certain provisions of the Jordan Lake Wastewater Discharge rule. I encourage
you to familiarize yourself with the remainder of this rule.
Nutrient Allocations. The Wastewater Discharge rule establishes the maximum loads of nitrogen and
phosphorus that can be released from wastewater treatment facilities into the Jordan Lake watershed.
The rule provides that these wasteload allocations are to be divided among the existing facilities in
proportion to (with specific exceptions) their 2001 permitted flows. It also provides that facilities
permitted to discharge 100,000 gpd or more are to receive nitrogen and phosphorus limits equivalent to
their individual allocations.
Your facility has been assigned nitrogen and phosphorus allocations. The allocations are expressed as
annual mass loadings delivered to the lake. Due to foreseeable losses between the discharge point and
the lake, they are also expressed as the equivalent discharge loads at the point of discharge. The
delivered and the corresponding discharge allocations assigned to your facility are as follows:

Nutrient Limits. Your facility will not receive new nutrient limits at this time. However, any nutrient
limits already in your NPDES permit will remain in effect.
If the facilities permitted for less than 100,000 gpd, as a group, approach their allocations for nitrogen
or phosphorus, the Division will consider whether nutrient limits are necessary to protect water quality
at that time. In the event that nutrient limits become necessary, the limits would equal your facility's
discharge allocations.
Nutrient Trading. The rule provides that, when one utility connects to another, the allocations held by
the closing facility are transferred to the remaining facility. The rule also provides for the trading of
allocations among dischargers within each of the major Jordan subwatersheds. Be sure to consult with
the Divisions NPDES staff before you consider selling allocation: transactions can have profound
implications for your facility and its permit.
If you have any questions regarding these allocations, please contact me at [phone] or at
mike. [e-mail].
