schedule for determining allowable nutrient loads and payments during Phase
(Table Al-l). If the total loads for the participating dischargers exceed the
allowable load for that year, the Association will pay an amount equal to times
Loads and Payments
(NCDEM, 1992; P. Blount, 1993)
To ensure the operation of the Nutrient Trading Program.
The results of WWTP engineering evaluations indicate that a majority of the
required nutrient reductions can be achieved through operational changes and
minor capital improvements. Consequently, the actual level of BMP funding is
likely to be substantially less than .8 million, which was estimated assuming all
nutrient reductions would be achieved via
The Association has agreed to make yearly minimum payments to the trading
fund. These funds are in addition to the 0,000 administrative payments and
will be used to fund BMP implementation. For 1991, 1992, and 1993, the
Association's total loading was less than the maximum allowable load.
Consequently, the Association has paid the minimum amount each year. When
a given year, the. Association will receive credit
calculating loading payments
All BMP credits will have a useful life
for minimum payments made
of 10 years unless otherwise specified.
Since July 1991, Association facilities have been performing weekly effluent
monitoring for total phosphorus, total nitrogen, and flow. The Association reports
monitoring data to NCDEM annually. NCDEM has developed a set of guidelines
for estimating flow and concentration if this information is not provided.
Currently, a pilot project is being conducted to study BMP effectiveness on Chicod
Creek, a coastal plain tributary to the Tar River. Chicod Creek has been identified
