FINDING OF NO SIGNIFICANT IMPACT (FONSI)
The Cary/Apex Water Treatment Facility Phase 111 Expansion Project
Wake and Chatham County, North Carolina
Dee Freeman
Secretary
fhe State Environmental Policy Act (G.S. 113A) requires that the Division of Environmental Health determine whether a proposed
major agency action will significantly affect the environment. The Cary/Apex Water Treatment Facility Phase III Expansion Project
is such a major action.
In order to determine whether the expansion of the Cary/Apex Water Treatment Facility, Raw Water Pump Station, and transmission
main improvements to the Cary/Apex Water Treatment Facility will cause significant environmental impacts, an environmental
assessment has been prepared. The environmental assessment is attached. It contains detailed information on the key issues, including
a brief description of the proposed project and a summary of probable environmental impacts with proposed mitigations. None of the
impacts were found to be significant. This project shall be reviewed as a NEPA- LikeiSEPA project.
On the basis of the analysis of the impacts as shown in the environmental assessment, no environmental impact statement (EIS) will
be prepared. This FONSI completes the environmental review record. The FONSI and Environmental Assessment shall be available
for inspection and comment for 30 days at the State Clearinghouse.
Summary of FONSI for publication in the Environmental Bulletin: After completion of an environmental assessment under G.S.
113A, a FONSI has been made in the case of the City of Albemarle Water Transmission Line Booster Stations and Storage Tank
Project Information supporting the need for the proposed project was reviewed, along with relative impacts, other alternative
approaches and mitigating measures.

Subject: [EXTERNAL] Permitting Questions regarding the Raw Water Pump Station on Jordan Lake
Hi Andy and Jennifer,
I am working on a project for the Towns of Cary/Apex. They are upgrading the raw water pump station and intakes in
Jordan Lake. During the EA process Jamie Shern stated that a Section 404 permit would be required and that once the
project is designed that he would be able to determine whether a Nationwide Permit or an Individual Permit would be
appropriate. Because this is a utility line project we were assuming a Nationwide 12 would be suitable. Basically we are
proposing to install new air burst pipes adjacent to the existing intake lines and then add a new lower emergency intake
in Jordan Lake. I have attached a plan sheet and also an aerial to illustrate the area that would be impacted. The
proposed air lines will be underground so temporary impacts would occur along the lake edge (replaced to existing
contours and revegetated once installed) and then once in the open water the new lines and apparatuses will be placed
on the existing pipe saddles or new pipe saddles to be installed for the new lower intake. From what I understand, no
trees would be removed from the 50' Jordan Lake buffers as the area for installation of the air burst lines is currently
mowed /maintained.
1 wanted to make certain that we are heading down the right path for submission of the permits and if you think a NW
12 is appropriate for this work? Also, we of course are in the Jordan Lake buffers but this area is currently maintained

for this use so I was wondering if the replacement of the air pipes would be exempt for buffers due to the Present and
Ongoing use? Any direction would be greatly appreciated.
Thanks,
Vickie

Vickie,
You are correct that the replacement work would be exempt from the Jordan Lake Buffer Rules if it is completely within
the footprint of the existing easement. If additional clearing is required then a buffer authorization would be necessary
because it looks like the project would have a maintenance corridor greater than 10 feet in width, which is an Allowable
use.
Our water quality certification (attached) that corresponds to NWP 12 requires written approval if there are impacts
other than those listed as exempt in the Jordan Lake Buffer Rules or if the maintenance corridor exceeds 15 feet in
width.
Please let me know if you have any questions.
Thanks,
Jennifer

Subject: Permitting Questions regarding the Raw Water Pump Station on Jordan Lake
Hi Andy and Jennifer,
I am working on a project for the Towns of Cary/Apex. They are upgrading the raw water pump station and intakes in
Jordan Lake. During the EA process Jamie Shern stated that a Section 404 permit would be required and that once the
project is designed that he would be able to determine whether a Nationwide Permit or an Individual Permit would be
appropriate. Because this is a utility line project we were assuming a Nationwide 12 would be suitable. Basically we are
proposing to install new air burst pipes adjacent to the existing intake lines and then add a new lower emergency intake
in Jordan Lake. I have attached a plan sheet and also an aerial to illustrate the area that would be impacted. The
proposed air lines will be underground so temporary impacts would occur along the lake edge (replaced to existing
contours and revegetated once installed) and then once in the open water the new lines and apparatuses will be placed

on the existing pipe saddles or new pipe saddles to be installed for the new lower intake. From what I understand, no
trees would be removed from the 50' Jordan Lake buffers as the area for installation of the air burst lines is currently
mowed /maintained.
I wanted to make certain that we are heading down the right path for submission of the permits and if you think a NW
12 is appropriate for this work? Also, we of course are in the Jordan Lake buffers but this area is currently maintained
for this use so I was wondering if the replacement of the air pipes would be exempt for buffers due to the Present and
Ongoing use? Any direction would be greatly appreciated.
Thanks,
Vickie
