Dear Ms. Karoly:
U
Af~~o"~ ~ ~J(J)
~~AwD sro~vv~;~~a #~
We are submitting the additional information requested from written correspondence
on April 19, 2007. Keller Environmental and Crowley and Associates appreciate Ms.
Annette Lucas' assistance with the level spreaders for this and other similar current
projects. We are requesting for NC Division of Water Quality (NCDWQ) written approval
under Section 401, Clean Water Act, 33 USC 1344. This will assist in compliance with
Water Quality Certification (WQC) 3404 and its accompanying Nationwide Permit (NWP)
14. We have addressed your included written comments in the following paragraphs.
1. Since the last submittal, a number of new additional level spreaders
have been added to the development. Please provide a plan detail
and a DWQ level spreader worksheet for each one.
Please refer to the attached Erosion Control Plan and level spreader worksheets.
2. Since level spreader number 2 has been redesigned. Please provide
a new DWQ worksheet for the new design.
Please refer to the attached worksheet for level spreader number 2. We have also
attached a CD containing the plan details.
If you should have questions or require additional clarification please feel free to contact
me at 844-7437 (office), 749-8259 (cell) or email: jay(a~kellerenvironmental.com.
