DWR SECTION
Attached is the semi-annual Stormwater Monitoring Report for the GE / GNF-A Facility in
Wilmington, NC for the second half of 2015. The sampling was performed during a measurable
rain event on 11/19/2015 and the data was received from the lab on 12/1/2015.
There have been no spills in the previous 6 months. In the past, however, there had been small
overflows from the process lift station during times of abnormally high flow. In the last report,
we noted that the site maintenance team was investigating options to improve capacity of the lift
station. That work has been completed. Pump speed was increased and bigger motors and
new controls were installed. The updated system can now pump 25-30% faster which should
alleviate future overflow potentials.
_ _ If you have any questions or need additional information, please call meat 910-819-5869.
Sincerely,
Global Nuclear Fuel - Americas
