RE: OEM 10# 93984, Nationwide Permit Application for an
activity located on pine Tree Drive, city of New Bern,
Craven County.

WETLANDS GROUP
WATER UAUTY SECTION

Dear Mr. Pridgen:

The North Carolina Division of Coastal Management has reviewed the
above referenced application for a Nationwide Permit dated November
17, 1993 pursuant to Section 307 of the Coastal Zone Management Act
of 1972 as amended. Based upon our review, we have determined that
the proposed activity is consistent with the North Carolina Coastal
Management Program provided the following conditions are met:

1. The activity described in the above referenced
application qualifies to receive one of the Nationwide
Permits described in 33 CFR Part 330 with the exception
of Numbers 17, 21, 24, and 34 which were found inconsis-
tent with the North Carolina Coastal Management Program.

2. A 401 Water Quality Certification is received, where
required, from the North Carolina Division of
Environmental Management.

This letter does not relieve you of the responsibility to insure
that all other State authorization and/or permit requirements are
met prior to implementation of the project. Please feel free to
contact me at [phone], Ext. 263, if you have any questions
or need further assistance.

RE:

Water Quality Monitoring
Marantha Island Project
Camden County

Recently Ms. Deborah Sawyer of our Washington Regional
Office asked me to propose a water quality monitoring plan for
your plan to connect several existing canals to the Turner's Cut
Canal near South Mills, N.C. As you are probably aware our main
concern is that water quality standards not be violated in the
Canal. Turner's Cut Canal is classified as WS-III Sw since it is
a water supply for Elizabeth City, N.C.

The following parameters should be measured at several
locations in the small existing canals as well as in Turner's Cut
Canal:

Physical:

Depth of system - present and future
Wind direction pattern
Sediment description - texture and particle size,
settleability
Lunar or wind tidal amplitude
Retention (turnover) time

Chemical:

Dissolved oxygen
Total dissolved gases
Temperature
pH
Turbidity
Sediment oxygen demand

.""

Mr. Doug Douglas

Biological:

Chlorophyll ~ and biovolume
Bacteria - fecal and total coliform
Aquatic fauna survey
Aquatic macrophytes - species and densities

Samples should be taken at several locations in the canal
system; at the surface, mid-depth and bottom; and conducted
throughout the summer at least weekly with a more intensive daily
study for diurnal trends.

A model will also need to be run to determine whether water
quality standards will be violated in Turner's Cut Canal and the
internal canal system by the connection of the canal system to
Turner's Cut Canal. This model will have to be a nontidal model
since lunar tides are inconsequential in this area.

As you can tell, the necessary data collection requirements
would be quite extensive for you to demonstrate that no violation
of water quality standards would result from connecting the
smaller canals to Turner's Cut Canal. If you are still
interested in pursuing this project, please prepare a detailed
water quality sampling plan and submit it in triplicate to me.
After it is reviewed by the Central and Regional Office staff to
determine its adequacy, I will notify you of any changes needed
prior to your initiation of the study.

I can be reached at 919-733-1786 if you have any questions.

RE: Water Quality Monitoring
Marantha Island Project
Camden County, NC

Dear Mr. Dorney:

Davis Environmental Consultants, Inc. (DEC) is assisting with environmental matters
associated with Marantha Island Development. The Marantha Island development is proposing to
connect approximately 6000 feet of their existing canal system (excavated more than 10 years ago)
to the Turners Cut Canal. By removing an earthen "plug" at the mouth of the canal system
navigational access will be established between the Marantha Island canals and Turners Cut. The
"plug" is approximately 15 to 20 feet wide. A culvert, which runs through the plug, allows water
to run both in and out of the canal system. Actual flow depends ~n wind driven tides, runoff from
storms and other events which affect water levels. Therefore, the canal system is already
hydrologically connected to Turners Cut. In addition, the owner reports sheet flow of runoff
waters from the canal system, through the adjacent swamps and into Turners Cut.

The water quality monitoring plan proposed in your letter of 04 Match 1993 will cost many
tens-of-thousands of dollars. We hope to design and perform the study in a manner that will keep
the costs down. To this end, we request information on threshold levels for the various parameters
which you have asked us to study. Specifically, please provide the levels which are acceptable and
the levels which are unacceptable for the following canal system parameters:

1) total phosphorus,
2) biological oxygen demand,
3) retention (turnover) time,
4) dissolved oxygen,
5) chlorophyll,
6) and bacteria-fecal and total coliform.

The outcome of the above evaluations will, to a great extent, determine if this project is
approved or denied. These parameters are relatively inexpensive to measure as compared to the
detailed study outlined in your letter. By comparing the values from the above evaluations with the
water quality parameter threshold levels which we have requested, we will be able to reach
important decisions about the project regarding state water quality standards and not incur the great
expense of the detailed study.

You indicated that Turners Cut Canal is classified as a WS-III SW waterway since it is a water
supply for Elizabeth City, NC. If available, please provide the water quality standards associated
with this designation, existing water quality conditions in Turners Cut and any standards for
discharge into Turners Cut. This information will also assist us in designing and performing the
necessary studies.

The Specific Use Standards found at Section .0208 of your State Guidelines for Areas of
Environmental Concern states that canals must be designed to "provide adequate water circulation"
and that "Canals shall be either straight or meandering with no right-angle corners." The
configuration of the canals at the Marantha Island project appear to be in conflict with these
standards, If conflict with these standards is of great enough concern to warrant denial of this
proposal then please advise us of that fact so that we will not waste money on water quality
studies. Also, we believe that it is important to remember that the canal system has been open to
Turners Cut by way of the existing culvert for more than 10 years. Therefore, our request is not to
open the canal system to Turners Cut but to increase the opening to accommodate boat traffic as
well as water circulation which presently exists. We request that you consider this in your
evaluation of the proposal.

By providing us with the information which we have requested above we will be able to
perform the required water quality stu'mS in a economical manner and possibly avoid unnecessary
work.

Thank you for attention to this matter.
