The purpose of this document is to submit a modification request for the Clean Water Act (CWA)

Authorization and the CAMA Major Permit An additional permit drawing /buffer drawing is included
in this modification request
Permit Site Impacted
Permit Site 5A
Additional buffer and stream impacts will result due to the need to realign pipe structure # 172 at
Station 257 +00 +/ with the existing Jurisdictional stream After discussion with the contractor looking
at future maintenance issues and long term stream impacts we propose to remove the flared end
section construct a drainage structure including frame & grate grade this area to drain to the grate
install additional pipe from the drainage structure to the 30 feet clear zone and to place Class B rip
rap at the outlet of the pipe This would require additional buffer impacts of 25 feet long by 10 feet wide
for a total of 250 sq ft (Zone 1 only) This would also require an additional 10 linear feet of stream
impacts to pipe this area

Including these additions total impacts for R 2510C are now 1 240 linear feet of stream 156 174 sq ft
of riparian buffers (102 817 sq ft Zone 1 53 357 sq ft Zone 2) Wetland impacts are unchanged
Additionally the Department requests the modified permit for this project have an extended expiration
date of December 31 2013
Compensatory Mitigation
The unavoidable additional impacts to 10 linear feet of stream a permit site 5A are below the 150 linear
feet threshold and therefore compensatory mitigation is not proposed Additional impacts to riparian
buffers are below the 1/3 acre or 150 linear feet threshold and therefore compensatory mitigation is not
proposed
