Subject: Badin Lake data
Enclosed are the data for Badin Lake that you requested. The lake has
been sampled every year since 1981 as part of the Ambient Lakes
Monitoring effort. The enclosed maps show the locations of the four
sampling stations. The two computer forms (STORET ALLPARM and
INVENTory retrievals) summarize all available data on the lake except for
this summer's samples. The 1987 data are presented in Tables 1, 2, and 3.
For your convenience, depth profiles of dissolved oxygen, temperature, and
pH at each station have also been graphed (Figure 1, A-D). Please contact me
if I can be of further assistance.

MEMORANDUM
TO: George Everett
THROUGH: Trevor Clemen
Steve Tedder
FROM: David Vogt
SUBJECT: Proposed Study Plan for Alcoa's WLA
I have reviewed the study plan proposed by FTN Associates
for determining the mixing characteristics of the cove in Baden
Lake in which Alcoa's waste is discharged. I have the following
comments:
1) EPA stongly advocates doing tracer studies during critical
design conditions. Near -to -design conditions are acceptable if
the obtained coefficients can be extrapolated to critical
conditions using hydraulic parameters.' Normally DEM recommends
that intensive studies be done in late August or early September
when water temperatures are high and flows are low. However,
since we are presently near low -flow conditions, a study done in
late September or early October may be permissable. This means
that both Alcoa and FTN Associates will need to accelerate the
planning and execution of the study.
2) FTN's proposal mainly addresses the determination of mixing
characteristics within the cove. While this is quite important,
spatial and temporal examinations also need to be made at the
interface of -the cove with the lake. Only if this is done can
a determination be made of the residence time of the pollutants
in the cove and the method by which they are transported into the
main portion of the lake.
3) FTN proposes to inject dye into the effluent "for a minimum of
2 hours" and then observe the dye concentration in a 3-dimensional
grid of sampling locations located within the cove. However, due
to the lack of mixing in•the cove, it may take days of continuous
injection before the dye reaches equilibrium at a sampling point
(this is especially true for,the outermost sampling locations).
Figure 1 illustrates this concern.
4) It is recommended that FTN take sediment samples in the grid
area sometime during the study to ascertain if there are elevated
concentrations of cyanide or fluoride in the sediments.
I hope that these comments are of use to you in deciding the
disposition of Alcoa's wasteload allocation. Please contact me if I
can be of further assistance.

WASTELOAD ALLOCATION AND MIXING ZONE STUDY
wo
rd 1.0 PROPOSED STUDY OUTLINE
FTN proposes to conduct a wasteload allocation and mixing zone modeling study for
ALCOA, Badin, NC works, on two separate NPDES permitted outfalls (002 and 009)
following applicable sections of EPA's Technical Support Document for Water Quality -based
Toxics Control. The parameters will include fluoride and cyanide (total and free) at both
outfalls and sulfate at outfall 002 only. To accomplish the study within the eight weeks
proposed in the request for quotation, we have divided the study into 4 tasks:
1. Data compilation and review.
2. Tracer study.
3. Simple steady state modeling.
4. Report preparation and review.
These tasks are described hereafter.
1.1 Data Compilation and Review
1.111.Object,ives
The objectives of this task are:
a. Define outfall characteristics (magnitude of momentum and buoyancy forces).
b. Define receiving body characteristics (stratification, flow regime).
C. Define critical conditions and scenarios to be modeled.
1.1.2 Procedures
a. A site visit will be made to ALCOA's Badin works as well as a visit to the offices of
the North Carolina Department of Natural Resources and Community
Development to discuss the project and collect information.
b. Outfall characteristics will be determined using information obtained from
ALCOA and the NPDES permits. Information required will include outlet
geometry (depth, orientation, and size of outfalI), flow rates (including seasonal
variability), and effluent density (dependent on temperature and dissolved and
suspended solids). This information is required to classify the outfall on the basis
1

of the magnitude of momentum and buoyancy forces. It will be used to select the
appropriate model and determine dilution characteristics.
C. The receiving water body characteristics that must be determined include reservoir
and cove morphometry, stratification patterns, flow regime including seasonal
variability and residence times, and reservoir operating procedures such as
withdrawal depths, pool level fluctuations, rule curves, etc. This information will
be obtained from the State of North Carolina and the operators and owners of the
Badin Reservoir, Yadkin Incorporated.
d. Pertinent State and Federal water quality standards will be obtained and used to
determine effluent concentrations that must be met outside the mixing zone.
1.1.3 Schedule
This task will require 2 to 3 weeks to complete after receiving the notice to proceed.
1.1.4 Products
a. Classification of the outfall to select appropriate models.
b. Identification of critical conditions and scenarios to be modeled. These will be
submitted to ALCOA and the State for approval.
C. Determination of dilution requirements to meet State and Federal water quality
standards.
1.2 Tracer Study
1.2.1 Objectives
The objectives of this task are:
a. Define effluent dilution characteristics.
b. Collect data for use in modeling effluent dilution under other conditions (i.e.,
model coefficient calibration data).
1.2.2 Justification
For existing outfalls, tracer studies are the most cost-effective and defensible studies to
determine mixing characteristics. They do not require the extensive data and assumptions
that mathematical models require. Their only limitations are that they show only what will
happen under the conditions they were conducted under. Ideally, tracer studies should be
conducted under the critical conditions to be modeled. In this study, because of the limited
2

time frame, consideration cannot be given to the selecting the optimum time for the tracer
study.
1.2.3 Field Procedures
a. Make in situ measurements to determine:
- Approximate dilution of effluent for use in determining tracer dosages.
- Background fluorescence.
- Cove stratification.
b. Inject Rhodamine WT fluorescent dye into the effluent for a minimum of 2 hours.
Rhodamine WT was developed especially for water tracing and is approved for use
by the State.
C. Define the temporal and spatial characteristics of the dye cloud with a three-
dimensional grid of sampling points established in the cove. A Turner Designs
field fluorometer will be used for in situ dye concentration analysis. Discrete
samples will be collected as backup.
d. Submit several discrete samples to an analytical laboratory for the analysis of
fluoride, sulfate and total and free cyanide to verify that dye and effluent dilutions
are similar.
e. Make velocity measurements at each outfall for use in modeling applications.
1.2.4 Schedule
The tracer study will be scheduled for the second or third week of the study. It is
projected to take about one week to study both outfalls. If possible, more than one dye study
will be conducted on each outfall. With sufficient lead time, cost reductions may be possible
with supplies, travel, etc.
1.2.5 Products
a. Summary of tracer study procedures and results.
b. Near and far field dilutions.
C. Calibration data for modeling studies.
d. Definition of mixing zone.

1.3 Model Simulations
1.3.1 Objective
The objective of this task is to predict effluent behavior under critical conditions and to
define the mixing zone.
1.3.2 Model Selection
a. No three-dimensional, dynamic, density dependent models are available.
b. Two-dimensional models are available but require detailed input data (e.g., hourly
solar radiation data, observed temperature profiles) and large amounts of
computer time (hours on large main-frame computers) that make their application
impossible within a six week period.
C. Only simple steady state models can be used such as those described in "Lake and
Reservoir Analyses", Part 1 - Mixing Zone and Toxic Waste]oad Allocations,
Chapter 5 of EPA's Technical Support Document for Water Quality -based Toxics
Control. The exact model to be used cannot be identified until the outfall and
receiving body characteristics have been defined; however two general types of
models will be used:
Near field dilution model - predicts initial dilution near the outfall pipe.
Outfall characteristics will determine if it will be a jet or pIume model.
Far field dispersion model - predicts mixing caused by the ambient flow
regime. Currents may be driven by convection (differential heating) or
advection (inflows or outflows from the reservoir).
1.3.3 Model Application
A maximum of four scenarios will be evaluated to determined critical conditions. These
scenarios would be selected only after consulting with and gaining the approval of ALCOA
and State officials. Examples of such scenarios might involve determining the behavior of the
effluent with a low outflow and strong stratification, with a negatively buoyant outflow rate
and stratification, and with a neutrally buoyant outflow and no stratification.
1.3.4 Schedule
The modeling study will be conducted during the two week period (weeks 4 and 5)
following the tracer study.
4

1.3.5 Products
The results from this task will be:
a. A description of the assumptions, limitations, and procedures used in the analysis.
b. Predicted dilutions for each of the scenarios.

4.0 MODEL SELECTION
As discussed in Section 1.3.2, only simple steady state models can be applied. No three-
dimensional dynamic density dependent models exist. The two-dimensional models that do
exist would require longer than the allotted six weeks to apply, require much more detailed
input data than is available, and require large amounts of computer time.
The steady-state models that will be used cannot be identified until the characteristics of
the outfall and receiving waters can be determined (Section 1.1.2); however, the models to be
considered fall into two general classes:
Near field dilution
2. Far field dispersion
Near field models determine the initial mixing at the outfall. If the velocity of the
effluent entering the reservoir at the outfall is high, a jet model will be used; if it is low, a
plume model can be used. If the density differences (caused by temperature and dissolved
and suspended solids concentration differences) are large enough, the buoyancy effects of the
discharge will be considered. The plume and jet models discussed in Chapter 5 of EPA's
Technical Support Document for Water Quality -based Toxics Control are examples of near
field models.
Far field dispersion models simulate the flow -generating mechanisms in the ambient
waterbody. In a cove these may be the naturally occurring convection currents caused by
differential heating along its axis or by inflows and outflows from the main body of the
reservoir. Only after the driving mechanisms are identified (as described in Section 1.1.2) can
the appropriate models be selected.

TOXICITY TESTING REQUIREMENT
The effluent discharge shall at no time exhibit chronic toxicity using
test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay proce-
dure (North Carolina Chronic Bioassay Procedure - Revised *February 1987) or
subsequent versions.
The effluent concentration at which there may be no observable inhibi-
tion of reproduction or significant mortality is xwf % (defined as treatment
two in the North Carolina procedure document). The permit holder shall
perform r (, monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed within thirty
days from issuance of this permit. Effluent sampling for this testing shall
be performed at the NPDES permitted final effluent discharge below all
treatment processes.
All toxicity testing results required as part of this permit condition
will be entered on the Effluent Discharge Monitoring Form (MR-1) for the
month in which it was performed, using the appropriate parameter code.
Additionally, DEM Form AT-1 (original) is to be sent to the following
address:
Attention: Technical Services Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting chemi-
cal/physical measurements performed in association with the toxicity tests,
as well as all dose/response data. Total residual chlorine must be measured
and reported if chlorine is employed for disinfection of the waste stream.
Should any test data from this monitoring requirement or tests per-
formed by the North Carolina Division of Environmental Management indicate
potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited docu-
ment, such as minimum control organism survival and appropriate environmen-
tal controls, shall constitute an invalid test and will require immediate
retesting. Failure to submit suitable test results will constitute a fail-
ure of permit condition.
