Now,therefore,the parties do mutually agree on the Scope of Services as follows: Scope of Services The services to be performed by the ENGINEER under this AGREEMENT may consist of those stated below.Further,it is understood and agreed that the date of beginning,rate of progress,and the time of completion of the work to be accomplished herein are essential provisions of this agreement;and it is further understood and agreed that the work embraced in this agreement shall commence upon execution of this agreement and after receipt of Notice to Proceed. Task 1—Data Review / Sampling Plan Review existing reports relative to historical sampling efforts.Obtain the necessary data to perform a DO study for several stream segments in the White and Illinois River basins. Samples shall be collected to be representative of river water quality at the time of sampling.In addition, the collection of benthic levels(sediment oxygen demand or SOD) in the White and Illinois River will be determined. Frequency of Sampling It is anticipated that there will be two, 1-day monitoring events for each stream segment. The monitoring events are suggested to occur in the May 1997,and July/August 1997 time frame.This will provide the information required to calibrate and verify the stream DO TUU138047/ATTACH_A.DOC A-1 • model.The data gathered in September 1996 will also be used as a comparison to confirm the model's accuracy. Sampling Points The anticipated sampling points in the White and Illinois River basins are listed in Table Nos. 1 and 2,respectively.The sampling points on the White River are the same locations as have been sampled in previous studies.Actual sampling/monitoring sites will be specifically located on a U.S.Geological Survey(USGS)map and the actual river mile location will be determined prior to start of the field sampling.

TUU138047/ATTACH_A.DOC A-5 Sample Collection, Preparation and Transport Coordinate with testing laboratory and establish procedures for field sample collection, preservation and transport to the laboratory for analysis.Establish sample identification protocol and sample containers to be used. Procure Field Equipment Arrange for field staff transportation,safety equipment,boat,communications,and other miscellaneous equipment needed for field sampling.Fabricate benthic SOD sample/testing device for use in the field. Quality Assurance(QA) Plan Prepare a written QA plan for the field sampling effort.Testing laboratory shall be certified by ADPC&E and will have the required QA plan for the analytical testing.Review field QA plan with ADPC&E prior to commencing of sampling effort. Task 3—Field Sampling / Analytical Testing Conduct field sampling as called for in the sampling plan.Deliver specified samples to the laboratory for analytical testing. Sampling Methods The methods of sample collection,preservation,measurements,and analysis shall be done in accordance with the latest edition of"Standard Methods for the Examination of Water and Wastewater"or other proven methods acceptable to the U.S.Environmental Protection Agency(EPA)Region 6,such as the updated version of the Federal Register,40 CFR Part 136,"Guidelines Establishing Test Procedures for the Analysis of Pollutants,and "Handbook for Analytical Quality Control in Water and Wastewater Laboratories."All samples will be collected under an EPA-approved quality assurance program.They will also conform to the, "Quality Assurance Project Plan for Arkansas'Ambient Water Quality and Compliance Monitoring."A quality assurance program will be developed which includes,but is not limited to,the elements in Table Nos.5 and 6 and includes calibration procedures for the DO meter.

Because the introduction of the dye TUU138047/ATTACH_A.DOC A-7 could be viewed as a pollutant,ADPC&E requires a special permit for this activity.This scope item includes obtaining such a permit and the field work involved in the dye test. Task 4—DO Model Development/ Simulation Purpose The objective of the sampling is to obtain data which can be used to determine the wastewater loading(quality and quantity)that can be discharged without causing a violation of water quality standards,in either the White or Illinois River basins.The model will characterize the stream,and provide a prediction of the impacts of the treated effluent prior to the actual introduction of new or increased discharge.The model will also be used to assess different discharge location scenarios in the Illinois River basin.These locations will include the existing Mud Creek discharge location along with potential new locations into Owl,Goose,Clear,and Hamestring Creeks,and the Illinois River. The modeling results will be used to develop effluent limitations which satisfy the DO criteria in both basins as set forth in the state Water Quality Standards.Upon acceptance by ADPC&E the model results will be used to amend the Area Water Quality Management Plan and the basis for issuing National Pollutant Discharge Elimination System(NPDES) permits. Results of this modeling will not be available until late 1997.However,a permit renewal application for the existing discharge permit at the Noland plant must be filed by May 1997. It is anticipated that this application will include the current effluent loadings.Following the modeling results and acceptance by ADPC&E,a revised permit will be requested based on the outcome of this study.Assistance in the negotiation of the new NPDES permit(s) cannot be accurately estimated at this time and is therefore not included in this work scope. Any assistance needed will be determined upon completion of this study and authorized at that time if desired. Modeling/Simulation In picking a model to be used for determination of effluent limitations,the different elements which could impact the stream quality were reviewed.The model must have the capability of incorporating those factors that can impact the DO levels which in this case include phosphorus,carbonaceous biochemical oxygen demand,and benthic oxygen demand.The model chosen is the Enhanced Stream Water Quality Model (QUAL2E).This model was chosen because of its ease of use and its familiarity to the State of Arkansas. QUAL2E is applicable to well mixed streams.It simulates the major reactions of nutrient systems,benthic and carbonaceous demand,atmospheric reaeration and their effects on the DO balance.It can predict up to 15 water quality constituent concentrations. QUAL2E simulates a series of nonuniform segments that make up a river reach and incorporate the effects of withdrawals,branches,and tributaries. This model is more accurate than the model originally used. The model choice may be re-evaluated based on a review of other models during setup and the results of the sampling events.A new model may be chosen if it is determined to be a TUU138047/ATTACH_A.DOC A-8 better fit for the data.Any change in model used will be discussed with the ADPC&E in advance. Approach The model will be set up once data begins to be received from the sampling events. Calibration and verification will occur as data are obtained.Once the model is calibrated and verified,it will be presented to ADPC&E for review and comment.Further activities will involve the analysis under different scenarios to determine the appropriate effluent limitations.A review will be done of the total phosphorus loadings on the White River in an effort to evaluate the impact of total phosphorus in the streams.No modeling of the phosphorus loading is anticipated. Modeling of the Illinois River will be based on data obtained from this study as well as sampling and analysis done by others.Data relative to the possible plant locations will be gathered. Task 5—Report Preparation Summarize sampling results,model development,and calibration.Document findings of stream DO simulation for the White River and the multiple stream segments within the Illinois River basin being evaluated.Present and review results of the study and report with the ADPC&E and EPA.
