We have done! ome figuring on the amount of NOx reduction we can acheeve @ our Hilburn
Dr. site fror1 od,r planried solar system. The system.�mnll be used to provide hot water, space
heating anc�so a cooling.
I
Todd St. James noted,earlier today that the new hard surfaces.will contribute from 4#to 8#
of nitrogen er'acre;-year and we would need to remove 40% of that.' We have only .345
acres of no h l rd Surfaces. That means we will contribute up to 1.104# of nitrogen to the
Neuse:per year
We have figured that we can displace up to 433 #of NOx from electricity generation by using
our solar syste,,m. This represents simple, on-site utirRation of the collected energy. If you
trace that baQ the,wire to a generating plant, that increases to almost 2900# of NOx per
year due W trilismliilon and generation inefficiencies: Assuming.that the nitrogen is a third
of the NOx WC would be displacing almost 970# of nitrogen that will not fall into the Neuse
or any other riv, r: \e—

We do draw h ily:on some of the old coal plants for energy' consumption around here, 1'
particularly Ifor urn rimer peak loads. �Y

i if we assume a are'dispCacing natural gas, we can show an improvement over 'the required
mitigation, of a�proxlmate[y 10 pounds per year.
We really woul' liko;y,du all to look on this project in an environmentally poslilve manner. We
think'we can hive a positive impact with this project We know .the intent of the rules is to
help clean lup bur Irivers 'and neither our client nor our firm are trying kto short' cut any
environmental regul n.
I
We would Sean} appreciate it if the numbers here and our intent could be taken into account
in your discussions today. , 1
