Study Plan 1

• Water Quality Study Plan

MIG 2 Water Quality and Quantity
6
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.

7
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.

8
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 2Location of NPDES Permits

• on Lake Martin

MIG 2 Water Quality and Quantity
10
Study Goal

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

11
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.

12
Revisions to Study Methodology

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

13
Study Plan 3

• Erosion Sedimentation

MIG 2 Water Quality and Quantity
14
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.

15
Study Methodology

• Erosion Hotspot Data Collection and Analysis
• Sedimentation Area Data Collection and Analysis

16
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.

17
Study Plan 4

• Water Quantity, Water Use, and Water Withdrawals

MIG 2 Water Quality and Quantity
18
Study Goals

• Provide a list of current water withdrawals from
  Lake Martin.
• Provide a description of the process used to
  permit water withdrawals.

19
Study Methodology

• Data Collection
• Data Analysis

20
Revisions to Study Methodology

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