Jerry,
According to the original stream determination letter regarding U-2524C dated October
15, 2012, Jordan Buffer Rules are not applicable to this project due to the project
reaching concurrence point 4A prior to Jordan Buffer Rules implementation. Because
buffer rules do not apply, NCDWR finds your request acceptable.
Please keep in mind that if any new impacts occur within the stream, buffer rules will
apply.
Please let me know if you have any questions or concerns,
Thanks,
April

April,
Per our discussion, I have attached two drawings. One is showing the original permit
plans for the 2' base ditch at Site 10 and the other is describing how NCDOT is
proposing to construct the ditch with Class B riprap in the base of the ditch with
Geotextile along the banks and tied into the stream with coir fiber matting and riprap
(See Detail U). NCDOT feels that this is necessary because of the anticipated high
volume of water that will outlet out of the Hazardous Spill Basin. It is feared that
without the riprap in the base of the ditch, NCDOT will face recurring maintenance
problems due to bank destabilization and sediment loss combined with the difficulty
and damage associated with accessing the site. No additional impacts are proposed
within the jurisdictional stream. Since only buffer impacts are anticipated within an
already permitted 2' base ditch, we are requesting that this work be performed under
an infield modification from DWR. Please let me know if you have any questions and if
you concur with our proposed plans.
