SCOPE STATEMENT

A. Introduction The Consultant shall conduct an aquatic assessment progran in the vicinity of the Consumers Power Midland Plant, Midland County, Michigan. Prelimi- nary assessment activities have been conducted for the Owner during 1977 and 1978. Data gathered during 1977 and entitled " Preliminary Water Quality Survey of "he Tittabawassee River, Midland, Michigan" (CMU 1977 Report) and 10 CFR Part 21 as amended, included herein and made a part hereof by reference, is furnished for the Consultant's information. Said data include species diversity and abundance determinations, a description of the site, sampling methods and techniques, study design rationale and URC guidelines for reporting defects and noncompliance.

B. Objectives The primary objectives hereunder are to design and perform an assessment program to adequately evaluate the effects of Midland Plant operation by comparison of control and experimental, operational and preoperational values of selected ecological parameters that shall satisfactorily indicate changes in distribution and abundance of the aquatic ecosysten near Midland Plant. The assessment program shall include identification and monitoring of definable pre-existing environmental stresses to provide a measure of the potential synergistic effects of future Midland Plant operation. Also, the following preoperational objectives shall be accomplished:

1. predict and assess the ecological implications of various cooling pond discharges on the Tittabawassee River during the Midland Plant operation, 2. describe the aquatic ecosystem of the Midland Plant cooling pond,

3 determine the quantity, importance and effect of entrainment and in- pingement associated with river intake procedures, h. document the origin and extent of fish novement and distribution in the Tittabawassee Fiver near the Midland Plant,

i .

i, .

5 define the relationship between Tittabawassee River temperatures above and below Dow dam, and at the point of the Midland Plant intake, and 6. conduct a groundwater monitoring program to assess the imperviousness of the clays and dikes of the Midland cooling pond.

C. Methodolory and Experimental Desicn

The methodology for this assessment progran shall include:

(1) the collection of quantitative and qualitative biological and lim- nological data, (2) utilisation of available data and literature, (3) development and application of a conceptual codel of the Tittabawassee

River / Midland Plant cooling pond system including a perspective of en- } trainment and impingement impact, (h) development and application of a riverwide Tittabawassee water quality cathematical model, and (5) appropriate statistical treatment of assessment data to prepare a defensible impact assessment and provide maximum usefalness of the data base.

Various aspects of this assessment progrs= including: Dissolved oxygen sags, blue-green algae bloons and the interactions of temperature with toxic materials shall include extensive literature reviews and be presented to the Owner as separate reports. (see Section D and Section C.2.)

The monitoring effort shall be coordinated with daily river level fluctua- tions which are a result of upstream hydroelectric generating activities of the Wolverine Power Ccepany. Accurate flow records are available from the USGS Station upstream of Midland Plant.

Data handling shall be accomplished as described in Secti;n F.

Prior to the initiation of assessment activities , the Consultant shall provide a detailed rationale for the proposed experimental design based on the s

results of preliminary assessment activities conducted for tha Owner by consultants during 1977 and 1978, as well as, the available pertinent literature. The experimental design shall indicate the level of detection af measurable change attainable for each parameter and the confidence with which each change can be detected (e.g. for periphyton, the design can seasure a 30% change with 90% confidence, etc. ). Experimental design shall include a comparisen of the percent change and level of confidence attainable for each parameter using a variety of sampling locations, frequencies and replications. The experimental design used for assessment activities shall be that which can measure a reasonable change with acceptable confidence and yet be practical and economically feasible. Sensitive species or groups of organisms that shall be used to reasure change for each parameter shall be identified and the rationale for their use shall be provided. In addition, the Consultant shall prepare in assesstent report of all data collected near Midland Plant by the Owner, during 1977 and 1978. This report shall be submitted in conjunction with the report providing the experimental design rationale as described in Section D.3 The result shall be the establishment of a firm experimental design that requires minimun future modifications and provides maximum usefulness and treatment of the resulting data base.

Rigorous statistical analyses shall be utiliced to verify the experimental design and be provided to the Owner by the Consultant as part of the comprehensive annual report (see Section D.5).

The following assessment nenitoring activities are provided as an indication of the scope of work the Owner assumes shall be required to properly assess the aquatic ecosystem. These activities are no_1 based on a finn experi- cental design. However, selected ecological parameters which may be satisfactory to indicate measurable change are indicated. The final experimental design modifications and rationale are to be provided by the Consultant as indicated above as a result of the report described in Section D.3 .

1. Long Ter: Assessment Monitoring The long term assessment monitoring program shall provide a comparison of preoperational and operational ecological conditions of the Tittabavassee River. Sampling locations shall be established to co= pare the aquatic ecosystem both upstream and downstrea= of the Midland Plant facility in order to indicate i==ediate and long-ter= effects of thermal, chemical and biological discharge. In addition, the identification and contribution of existing environmental stresses to the surrounding biota shall b9 defined. Proposed sampling locations to accomplish these objectives are schematically represented in Figures 1 and 2, attached hereto and made a part hereof. Proposed parameters, sampling gear, frequency, number of replicates, duration of sampling and number of samples to be collected are set forth in Table 1 hereto.

a. Phytoplankton - Duplicate wholevater samples shall be collected during the daily flow regime in April, June, August and October 1979 and sampling locations indicated in Table 1 and illustrated in Figure 1 hereto. Phytoplankton densities, relative abundance of dominant groups and identification of dominant species (t55 of the total) within each group shall be determined. Biovolume for dominant species and chlorophyll a values vill be determined following EPA standardized techniques. Samples shall be retained by the Consultant in the advent that additional analyses are required.

b. Perithyton - Duplicate artifical substrates (Periphytometer II) shall be utilized during April, June, August and October 1979 at sampling transects indicated in Table 1 hereto and illustrated in Figure i hereto. Sampling locations within a transect shall be selected to represent extremes of river flow velocity and to compare the effects of thermal addition. Sampling with Feriphytometer II's shall coincide with tacroinvertebrate artificial substrate collections (see Section C.l.d to follow). In addition, selective water quality parameters shall coincide with the above activities (see Section C.l.f to follow) . ..

. *. e

Periphyton densities, relative abundance of dcminant groups and identification of dominant species (25% of the total) within each group shall be determined. Samples shall be retained by the Consultant in the advent that additional analyses are required. Biovolume of the dominant species and production estimated by the amount of chlorophyll a produced for each of the Periphyto=eter data sets vill be determined following EPA standardized techniques. In order to validate the co== unities that are observed on the artificial substrates and their species diversities, complementary analysis on samples obtained from " naturally" occurring substrates (rocks, logs, floats, etc.) vill be performed.

c. Zooplankton - Duplicate tcvs (oblique) with a 6h p plankton net and a mounted flov=eter, shall be made during the daily flow regime in April, June, August and October 1979 at sa:Pling locations indicated in Table 1 and illustrated in Figure 1 hereto. Identification of dominant species (r5% of the total) within each group shall be determined. Density estimates and diversity shall be reported. Samples shall be retained by the Consultant in the advent that additional analyses are required.

d. Macroinvertebrates - Circular rultiple plate artificial substrates with an effective area of 0.052 = shall be utilized to monitor =acroinvertebrate populations in the Tittabavassee River (during 197T and 1978, an effective area of 0.13 =2 was sa= pled). Two artificial substrates shall be suspended frc= a buoy at locations coinciding with periphytometer placement and allowed to colonize for six weeks.

Relative abundance of dominant groups and identification of dominant species (E5% of the total) within each group shall be determined. Samples shall be retained by the Consultant in the advent that additional analyses are required. Bic ass estimates shall be determined by volumetric displacement and calculations made of relstive abundance, densities and species diversity.

. .

. . .

Benthic =acroinvertebrates shall also be sampled using a Triplex ponar. The triplicate samples from a single Triplex ponar grab shall be used to account for one macroinvertebrate sample, the sediment chemistry sample and the sediment particle size sample. Replicate samples shall be taken at locations indicated in Table 1 and illustrated in Figure 1 hereto. Samples shall be treated similarly to those collected by artificial substrate and be collected during June, August and October 1979

e. Sediment - Sediments shall be collected in coordination with =acroinvertebrate sampling with the Triplex ponar as indicated above. Rando: samples ' hall be characterized by particle size analysis at each transect. A substrate map, which generalizes substrate type for the entire study area, shall be constructed during June and October by the Consultant.

Background concentrations of copper, silver, arsenic, beryllium, cadmium, manganese, mercury, selenium, iron, nickel, lead, zine and total ceganic carbon shall be collected semiannually at locations indicated in Table 1 hereto and illustrated in Figure 1 hereto. In addition, an evaluation frc= existing =cnitoring data and permit requirements of neighboring industrial discharges shall be conducted with emphasis to defining the potential for sedimental accumulations of substances such as PC3's, F33's, Hg, Cu and Cr. The Consultant shall provide the Owner a separate report which evaluates these data (see Section D).

f. Water Chemistry - Water quality parameters, frequencies, techniques and sampling locations are indicated in Table 2. Samples shall be collected within one meter of the surface with the exception of samples taken with continuous monitoring equipment. A minimum of ten percent of all sa=ples taken on each sampling date shall be collected in duplicate at randomly selected sites. Data frc= duplicate samples shall be used to indicate: (a) intersample and instantaneous spatial variation; (b) sample collection error; and (c) analytical precision and accuracy. .

. - .

Quarterly dissolved oxygen levels shall be determined at top, mid and bottom depths as applicable. Data shall be analyzed to determine whether dissolved oxygen levels warrant multiple depth sampling. Ultrite-nitrate and ammonia nitrogen, pH, BOD and temperature determinations shall coin- 5 cide with quarterly dissolved oxygen sampling.

In order to determine the relationship between water temperatures in the Tittabavassee River near the Midland Plant, data shall be collected and analyzed at three locations in a transect of the Tittabavassee River immediately above and below Dow dam and at the Midland intake structure. Ryan Thermographs shall be utilized to record temperature data. Instrenent calibration and accurate manual temperature probe comparisons, as well as quality control records shall be carefully maintained. Temperature data collected shall be compared with the Dow das continuous monitoring system. Data shall be collected for one year, unless an interim report analyzing data collected from April 1 through October 31, 1979 (see Section D) is con- clusive and allows a reliable comparison using appropriate statistical

analyses.

In addition, the potential of a dissolved oxygen sag in the Tittabavassee River as a result of thermal and/or biological discharge shall be projected

and evaluated.

g. Fisheries - Fisheries sampling shall be conducted as indicated in Table 1 hereto at locations illustrated in Figure 2 hereto. All adult and juvenile fishes collected by electroshocking, seining and hoop neeting shall be identified to the lowest practical taxonomic level (generally species), weighed, measured, breeding condition established and external parasitism noted. A collection of voucher specimens shall be maintained by the Consultant.

Three hundred feet of shoreline shall be electroshocked at locations indicated in Table 1. The duration of each sampling effort shall be recorded .

for obtaining catch per effort calculation 3. Age class structure shall be determined by scale removal and aging procedures for abundant species. Population sizes, residency and fish movements shall be generalized by mark and recapture techniques. In addition, condition factors and length frequency histograms shall be recorded for dominant fishes.

Seining shall be conducted as indicated in Table 1. Length frequency histograms shall be constructed for juvenile and adult fishes. Qualita- tive analyses of larval fishes collected by seining shall include the relative abundance and size distribution of dominant (E5fs) larval fishes. If the number of fish eggs and larvae is greater than 200 in any one sample, apporpriate subsampling techniques may be employed. Seining shall be acecmplished with a 100 ft. by 6 ft'. haul seine with 1/16 inch bar mesh. This seine shall be used to sample two adjacent 100 ft. sections of shoreline at each sampling location during each sampling period.

The frequency of electroshocking and seining vill be useful for documenting spawning activities, including migrations, in the Tittabavassee River near Midland Plant. To supplement fisheries data and document the presence of fish species not readily collectable by seining and electroschocking (i.e. , channel catfish), hoop netting sha?.1 be utilized as indicated in Table 1 hereto. These data shall be analyzed as described for electroshocking, above.

In addition, a standing crop estimate shall be determined by seining during lov flow periods. Fishes collected shall be returned to the river unharmed.

h. Ichthyoplankton - Ichthyoplankton sampling shall be conducted as indicated in Table 1 hereto at locations illustrated in Figure 2 hereto. Duplicate oblique tows and surface neuston net tows shall be collected during the day and night. Ichthyoplankton samples shall be identified to the lowest practical taxonomic level (generally species) and enumerated in egg and/or 5 millimeter length groups. If the number of either fish eggs or larvae is .-

- .

greater than 200 in any one sample, appropriate subsampling techniques may be employed.

2. Cooline Pond Monitoring The objectives of cooling pond monitoring shall be to describe the aquatic community of the cooling pond and to predict the effect of intermittent cooling pond discharge on the Tittabavassee River. The Consultant shall provide the Owner with separate special subject reports (see Section D) which evaluates cooling pond monitoring activities in the following areas:

a. describe the aquatic ecesystem,

b. predict the resident cooling pond fishes response to thermal loading,

c. evaluate the potential of a cooling pond blue-green algae blocu, its contribution to a potential dissolved oxygen sag and conduct bioassays which establish control reasures if required,

d. evaluate the interaction of thermal discharge with the following toxicants in the Tittabavassee River: 2enzene, styrene, an=cnia, zinc, P33, PC3, pentachlorophenol, tetrachlorophenol, trichlorophenol, dichlorophenol, hexachlorobenzene, 2,h,5-T and TCDD. Include determination of baseline concentrations of the above materials during the vinter of 1979 Single water and sediment samples at dontrol Location Ag (Figure 2 hereto) and at a location in the immediate area or the future Midland discharge shall be

analyzed.

The aquatic ecosystem of the cooling pond shall be defined by investigating the following parameters: Phytoplankton, periphyton, racrophytes, scoplankton, macroinvertebrates, sediment, water chemistry, fisheries and ichthyoplankton. Sampling gear, locations, frequencies, nu=ber of replicates and total number of ss=ples are indicated in Table i hereto. Locations to be sampled are sche- natically represented in Figure 3 hereto. Field, laboratory and data handling techniques described for the long tern assessment progrs= shall be employed.

.- .

In addition to techniques utilized in the long term assessment program, surface and botton gill netting and bottom trawling shall be utilised to enhance the fisheries assessment of the cooling pond. Fishes shall be evaluated as described for electroshocking (see Section C.1.g). A preliminary survey shall be conducted in the cooling pond to identify the species and distribution of macrophytes. Upon determination of the species present, a biomass (fresh weight) estimate shall ce made at the end of the season of maximum growth for most species. Estimates of the total biomass shall consider the annual growth characteristics of the species involved and the spatial distribution of these species. A map of the cooling pond shall be constructed which indicates the presence and abundance of macrophytes.

3 Inninzement and Entrainment Monitoring Impingement and entrainment tonitoring shall be conducted during the Midland Plant cooling pond filling activities. During 1979, pond filling shall occur for a minimum of h0 days.

All fishes impinged shall be separated from debris. The total number and total weight of each species impinged shall be recorded. A subsample of 30 individu- als of each species impinged shall be measured and weighed. Age class structure shall be deternined by scale removal and aging procedures for the most dominant species. Length frequency histograms shall be constructed. Detailed pond fill operational data shall be provided to aid the evaluation of impingement data. The significance of impingement losses shall be evaluated within the findings of the long term assessment =cnitoring program.

In addition, the Consultant shall assist the Ovner in the development of citiga- tion procedures, if necessary, based on 1978 data as well as data collected during 1979 Periodic velocity measurements shall be made near the intake structure during pond fill activities to help evaluate impinge =ent and the Midland intake structure design.

. . .

Entrainment monitoring shall be conducted during two 2h-hour periods per week if pond fill activities allow. Triplicate day and night samples shall be collected at the cooling pond intake to coincide with long term asseccrent monitoring for ichthyoplankton. Samples shall be analyzed as described in the lor g term assessment =cnitoring discussion (see Section C.l.f).

h. Documentation of Fish Micration and Distribution Impingement monitoring during the fall and vinter of 1978 indicated the presence of numerous young of the year yellow perch in the Tittabavassee River, near the Midland Plant. In an attempt to dccunent the origin and extent of these fishes, electroshocking activities and nonitoring of the Dow dam fish ladder shall be employed.

Sarpling locations shall include opposite shorelines at Sanford Lake, below the Sanford Lake Dam, the Pine and Chippewa Rivers, above and below t?e Dow das near the Midland Plant intake structure, near the Freeland Road Bridge and at the mouth of Saginav Bay. Sampling shall be conducted biveekly during the last two weeks of September through the first two weeks of December (T veeks). Total numbers of yellow perch in each length group and associated age class shall be documented. Data shall be evaluated in an attempt to establish the origin of young of the year yellow perch: 1.e., determine if the yellow perch are endemic to the Tittabavassee River,are migrants from Saginaw Eay, are released at Sanfo.d Dan, and/or are mig: ents from the Chippewa and Pine Rivers. A spring survey shall be conducted to determine where in the Tittabavassee system yellow perch may be spawning. Visual surveys shall be supplemented with weekly oblique plankton net tows in Sanford Lake, the Pine and Chippewa Rivers and the south

of Sa6 1naw Bay, during April and May 1979
