Study Plan 1

Water Quality Study Plan

MIG 2 Water Quality
and Quantity

April 2, 2008

Study Goals


Prepare an adequate baseline of water
quality information for Lake Martin and
the Project tailrace.



Develop a Plan to evaluate any
proposed Project operation changes
identified during relicensing.

April 2, 2008

Study Methodology


If review of the project operations and downstream flood analyses
identifies a potential increase to the winter rule curve or change to the
amount of time the summer rule curve is in effect at Lake Martin, the
implementation of that change and any potential impacts to water quality
of the project will need to be analyzed.



Continuation of Baseline Water Quality Sampling


APC will continue their collection of water quality sampling on the
lake and tailrace to be used in development of the 401 water quality
certification application.



Analysis of Nutrient Levels in Lake Martin


Nutrient levels in the lake may need to be addressed in relation to
lake classifications. If so, APC will examine nutrient inputs into the
lake in relation to observed lake productivity. This will be developed
with ADEM and with the MIG 2 as deemed necessary.




April 2, 2008

Revisions to Study Methodology


APC will continue to collect water quality
sampling on the lake and tailrace to be used
in development of the 401 water quality
certification application.



If necessary, nutrient levels in the lake may
be reviewed in relation to lake classification.




Study Plan 2

Location of NPDES Permits

on Lake Martin

MIG 2 Water Quality
and Quantity

April 2, 2008

Study Goal


Develop a list of all NPDES permits on
Lake Martin and identify their location
and pollutant load.

April 2, 2008

Study Methodology

Data Collection Techniques


Existing information will be used to facilitate data collection for this
study. First, a request for up to date NPDES data from the ADEM
will be made.


Once a list of NPDES permit locations is complete and other existing
literature has been complied and reviewed, a draft report will be
issued to Martin Issue Group (MIG) 2 for their review and comment.
The report will include a list of the NPDES locations, owners, and
effluent limits. Comments received from MIG2 will be incorporated
into a final report.

Data Analysis


Other than a literature review, there will be no data analysis
associated with this study. The GIS overlays may be compared with
areas of Lake Martin experiencing water quality problems to better
understand the impacts of discharges.


April 2, 2008

Revisions to Study Methodology


The report will include a list of the NPDES
locations, owners, and effluent.


Study Plan 3

Erosion & Sedimentation

MIG 2 Water Quality
and Quantity

April 2, 2008

Study Goals


Identify “hot spot” erosion areas on the
lake or tailrace.


Investigate some tributaries for
“headcutting”.


Identify areas that currently have or could
potentially have nuisance aquatic
vegetation.

April 2, 2008

Study

Methodology



Erosion Hotspot Data Collection and
Analysis


Sedimentation Area Data Collection and
Analysis


April 2, 2008

Revisions to Study

Methodology


Tributary headcutting will be investigated
on at least two of the larger tributaries of
the lake.


Sedimentation areas will be identified
with LIDAR and photography information
on the lake.


Some verification through field
observations.


Surveys for nuisance aquatic vegetation.

Study Plan 4

Water Quantity, Water Use, and Water
Withdrawals

MIG 2 Water Quality
and Quantity

April 2, 2008

Study Goals


Provide a list of current water withdrawals
from Lake Martin.



Provide a description of the process used to
permit water withdrawals.

April 2, 2008

Revisions to Study Methodology


There have been no substantive changes
to the November 2007 Draft Study plan.
