FROM: Mark Castleberry, Environmental Enginee

SUBJECT: Copper and Zinc Limit for Teledyne Allvac
Howard N. Lee, Secretary
There are no North Carolina numerical water quality standards for copper
and zinc at this time. They, however, are covered by Section .0208 of
Title 15 Chapter 2. This section states "the concentration of toxic
substances in the receiving water, when not specified elsewhere in this
section, shall not exceed one -one hundredth (0.01) of the 96-hour LC50"
The Biological Monitoring Group of Technical Services is planning
andzinc.
run bioassey tests to determine the 96-hour LC50 for copper
These tests will probably be run this spring.
Presently, we are recommending that permits with copper or zinc limits -
use the BPT value with the stipulation that the limits are subject to
revision once the 96-hour LC50 concentration are determined. For Teledyne
Allvac BPT values, we suggest that you use the present permit limits for
copper and zinc.
If you have any further questions on this matter, please let us know.
