Appendix 5. Calculation of Trading Values for Phase
and Phase
2.
Phase II Trading Value
ranges presented in this report, the North
Based on the
Carolina Division of Environmental Management selected the following scenario
as the
for estimating a trading value for Phase II of the Nutrient Trading
Program:
anaerobic lagoons
Practice:
at 2 times
undersized lagoon with land
Preexisting practice:
the agronomic rate
20 years
Lagoon life span:
Nutrient:
Our estimated cost-effectiveness range for the above scenario is from to
per kilogram of nitrogen reduced (Table ES-l). To estimate a single trading
value, NCDEM multiplied the median of this range
N) by a safety factor of
2 and then added a 10% administrative cost. The resulting figure was .60,
which was rounded to
N.
