Dear Mr Krebs
As stated in our letter dated May 24 2012 we have revised the Preconstruction
Notification Form for the subject project On behalf of the City of Conover and Catawba
County, we are submitting that revised document as an enclosure with this letter Also included
in that enclosure are the associated plan sheets for each individual crossing an overall project
map with indices of each stream crossing and detail sheets for use in stream restoration
The revisions to the proposed stream crossings modifies their impacts so that only four
(4) of the crossings will have a permanent impact and the overall length of permanent impact
will be a maximum of 130 linear feet These revisions to the stream crossings will also be
reflected in the record drawings submitted to the Division of Water Quality
If you have any questions regarding these revisions please do not hesitate to contact me at
[phone]
Sincerely
