Final Report Reach J Bed Stability Monitoring Project
Upper Tittabawassee River The Dow Chemical Company
January 12, 2010
Background On August 14, 2008 Dow submitted a Sediment Bed Stability Monitoring Work Plan Reach J (RJ‐187+50 to RK‐206+00). Based upon subsequent discussions with the MDEQ a revised work plan was submitted on August 21, 2008 for MDEQ review and approval.
On September 17, 2008 Dow received Al Taylor’s email approval of the August 21, 2008 revised Sediment Bed Stability Monitoring Work Plan except for the toxicity testing component. Pursuant to a follow‐up email from Delores Montgomery received on September 17, 2008, Dow provided MDEQ with a letter on September 23, 3008, that outlined the applicable date changes for implementation of the Work Plan, based on the partial approval. The following is a summary of activities completed in support of the Reach J Sediment Bed Stability Monitoring Work Plan.
Bed Stability Monitoring in Reaches J and K: All bed pins were installed during August, 2008. Bed pin elevation surveys were conducted during the weeks of September 23rd, October 22nd, November 24th, 2008, August 10th, September 15th, October 19th, and November 16th, 2009. Bed pin cross‐section charts for the four transects in Reach J/K and eight survey events are provided in Attachment A. These cross‐sections provide an indication of the variation in bed elevations over the 16 month monitoring period. Reach J Sediment Toxicity Testing: On November 20, 2008 MDEQ provided Dow with an approval to use ERM as the contract lab to conduct the sediment toxicity testing for Reach D and Reach J. Consistent with the September 23, 2008 schedule for the Reach J Sediment Bed Stability Monitoring Work Plan (Work Plan), the sediment toxicity samples from Reach J (Reference Area and RJ‐195+00‐IC37) were collected on September 26, 2008.

The September and October 2008 Reach J PCAP Progress Reports provided confirmation that Reach J sediment toxicity samples were collected on September 26, 2008. The Reach J Sediment Toxicity Samples were processed consistent with the Work Plan and were submitted for toxicity testing during the last week of February 2009. The Reach J Sediment Toxicity Testing was completed at ERM during March 2009 and the Sediment Toxicity Test Report was initially provided to MDEQ with the April 2009 Reach J IRA Progress Report. For reference, a complete copy of the Reach J Sediment Toxicity Test Report is included in Attachment B. Analysis of Primary and Secondary COI Sediment Samples from Reach J (Reference Area and RJ‐195+00‐IC37): Samples were collected on September 26, 2008. The data summary report for primary COI analyses was initially provided to MDEQ with the April 2009 Reach J IRA Progress Report. The data summary report for primary COI analyses is provided in Attachment C and the data summary report of secondary COI analyses is provided in Attachment D of this Progress Report. Analysis of Primary and Secondary COI of Sediment Samples from Reach K (RK‐202+75 and RK‐203+75): Samples were collected on September 26, 2008. Samples were submitted for analysis of primary and secondary COI on January 22, 2009. The data summary report for primary COI analyses was initially provided to MDEQ with the April 2009 Reach J IRA Progress Report. The data summary report for primary COI analyses is provided in Attachment C and the data summary report of secondary COI analyses is provided in Attachment D of this Progress Report. Information developed from work performed under the Reach J/K Bed Stability Monitoring Work Plan supports the following conclusions:
• The in‐channel J/K deposits containing elevated contaminant concentrations occur in an accreting point bar along an inside meander bend of the river, contiguous to Dow Chemical property. Geomorphologically, this accreting point bar is a stable formation in equilibrium with the hydrologic forces and sediment transport characteristics of the river at this location. These deposits will remain in place so long as the river morphology does not change.
Reach J Bed Stability Monitoring Final Status Report - Upper Tittabawassee River The Dow Chemical Company January 12, 2010 Page 3 of 4
• The contaminant signature in these deposits, and the position of the deposits within the accreting point bar, laterally and vertically, indicate the deposits are historical.
• Spatially continuous, high resolution bathymetry has been recorded annually in this area as part of the overall TR site characterization effort. This information was collected to map the river bottom conditions over time. Differential analysis of bathymetry taken in 2007, 2008 and 2009 indicates a net accretive/depositional setting across the J/K point bar (see attached Figures. A detailed discussion of the bathymetric procedures and findings is included in the June 2009 Tittabawassee River GeoMorph® Site Characterization Report (Volume III Exhibit III‐2B, and Volume VI, Exhibit VI‐3).
• Bed pin monitoring during eight survey events spanning 16 months confirms that the J/K point bar is stable. This set of measurements reveals an active bed depth in the area of 0.3 to 1.4 feet. Except where local hydraulic influences occur (e.g. tree fall‐in adjacent to RJ‐186+50‐EP1), the active bed depth is minimal along the shoreline of the inside meander bend, and increases with proximity to the thalweg.
• The TEQ concentration in the active bedload layer in Reach J/K is less than 100 ppt TEQ. This active bed layer covers the historic deposits in the J/K point bar. At only two locations does the TEQ in the surface layer exceed 1,000 ppt (RJ‐195+00‐IC37 and RK‐205+50‐IC25), and these locations are immediately adjacent to the shoreline where the deposition rate is less because it occurs only during high flow events.
• Given that the majority of the deposits with elevated contaminant concentrations are buried beneath relatively clean sediment, the potential for human exposure through direct contact is minimal.
• Sediment toxicity of the deposits with elevated contaminant concentrations was assessed using two species of organisms, Hyalella azteca and Chironomus dilutus. For both species, there were no significant differences in mortality rate as compared to control

sediments. The sediment toxicity of these deposits is, therefore, considered to be low.
• Based upon the stability of the accreting point bar, the low potential for human direct contact, and the low sediment toxicity, the overall assessment is this area in Reach J/K presents a low near‐term risk potential. Accordingly, Dow will address these in‐channel deposits in the determination of final remedy for this portion of the Tittabawassee River.

Notes:1. Multibeam bathymetry data collected using Hypack/Hysweep.2. Multibeam bathymetry processing performed using Hypack MBMax, CARIS HIPS, IVS3D Fledermaus and Tetra Tech developed software.3. Charts and other data products developed using ArcGIS and IVS3D Fledermaus.4. Bathymetric surveys conducted from April-May, 2007, March-April, 2008, March-April 2009.5. The bathymetry data represent conditions in the river at the time of collection. Bedforms are expected to change over time due to the varying water flows in the river.6. Bathymetric surfaces derived using weighted moving average algorithm and a one foot grid.7. Horizontal and vertical control established by Arbor Land Consultants Inc. Control network referenced asTittabawassee Geodetic Control Network (TGCN).

Notes:1. Multibeam bathymetry data collected using Hypack/Hysweep.2. Multibeam bathymetry processing performed using Hypack MBMax, CARIS HIPS, IVS3D Fledermaus and Tetra Tech developed software.3. Charts and other data products developed using ArcGIS and IVS3D Fledermaus.4. Bathymetric surveys conducted from April-May, 2007, March-April, 2008, March-April 2009.5. The bathymetry data represent conditions in the river at the time of collection. Bedforms are expected to change over time due to the varying water flows in the river.6. Bathymetric surfaces derived using weighted moving average algorithm and a one foot grid.7. Horizontal and vertical control established by Arbor Land Consultants Inc. Control network referenced asTittabawassee Geodetic Control Network (TGCN).

1.0 INTRODUCTION Environmental Resources Management, Inc. (ERM) performed 10-day Hyalella azteca sediment toxicity tests and 10-day Chironomus dilutus sediment toxicity tests on samples of sediment collected from Reach J in the Tittabawassee River, adjacent to the Dow Chemical Company facility located in Midland, Michigan. Samples were collected on 1 October 2008, and transported to ERM’s Aquatic Toxicology Laboratory in Holland, Michigan, for testing. Test endpoints for the 10-day assessments included both survival and growth (weight).
2.0 METHODS AND MATERIALS The testing protocol used for these exposures followed guidance provided in Methods for Measuring the Toxicity and Bioaccumulation of Sediment-associated Contaminants with Freshwater Invertebrates (Second Edition), March 2000, EPA/600/R-99/064. Details regarding sample description, test organism source and acclimation, specific test procedures, and data collection and reduction are provided below. Sample Description ERM’s Aquatic Toxicology Laboratory received two sediment samples from Ann Arbor Technical Services, Inc. (ATS) on 6 March 2009. The samples were labeled as follows:
Project ID/Number Sample Identification Sample Date Dow/D052-TRP RJ-195+00-IC37-0.0-1.0 1 October 2008 Dow/D052-TRP RJ-187+50-IC-NE-0.0-1.0 1 October 2008
Each sediment sample was received in six (6) 1-liter plastic containers. Upon sample arrival, each sample was assigned a laboratory identification number, measured for temperature, and stored under refrigeration (4 ± 2 degrees Celsius [°C]) until used. Appendix A contains a copy of the Chain-of-Custody form. Laboratory control sediment was collected 10 March 2009, from a private lake located in Ottawa County, Michigan, and included in the test design. Prior to use, the laboratory control sediment was thoroughly homogenized, sieved through a 0.5-millimeter (mm) screen to remove indigenous organisms, and frozen until used.
ERM 1 Dow Chemical Company/0066953.0070/04/15/09
Test Organism Source and Acclimation H. azteca and C. dilutus used during each set of exposures were shipped from the supplier (Aquatic Biosystems, Inc., Fort Collins, Colorado) via overnight courier and arrived the day of test initiation. Approximately 50 percent of the water was exchanged with test overlying water upon arrival and the cultures were adjusted to test temperature. At test initiation, H. azteca were 10 – 12 days old and C. dilutus were in their second instar. Specific Test Procedures Twenty-four hours prior to test initiation (Day -1), each test sediment was homogenized and visually inspected for large predatory nymphs or other organisms that could possibly affect the test results. No indigenous organisms were found in any of the test sediments. Exposure chambers consisted of eight (8) 300-millilter (mL) lipless glass beakers or 1-pint mason jars per sediment type. Following sample homogenization, 100-mL portions of each sediment sample were added to each of the eight replicate exposure chambers, followed by 150 mL of overlying water. Overlying water consisted of dechlorinated Holland Township tap water. The Township draws its water from Lake Michigan. The tap water was dechlorinated with treatment through one 1.5-cubic-foot activated carbon bed. Each set of replicate test chambers were placed in an environmentally controlled water bath (i.e., temperature 23 ± 1°C under fluorescent lighting on a photoperiod of 16 hours light and 8 hours dark) and overlying water renewals were initiated. Renewals were performed using an automated water-delivery system which supplied two volume additions of overlying water per day. On Day 0 and Day 9, measurements of overlying water temperature, dissolved oxygen, pH, total ammonia, conductivity, hardness, and alkalinity were performed on a representative test replicate from each sediment sample. On test days 1 – 8 and 10, overlying water measurements were limited to temperature and dissolved oxygen. Test initiation began on Day 0 with the impartial distribution of ten H. azteca and ten C. dilutus each to designated intermediate holding cups. The organisms were handled with a wide-bore glass pipette. The organisms were then transferred from the intermediate vessel to a randomly chosen test replicate. The H. azteca test organisms were fed a 1.0-mL suspension consisting of yeast-Cerophyll-fermented trout chow (YCT) once per day. C. dilutus
ERM 2 Dow Chemical Company/0066953.0070/04/15/09
were fed a 1.5-mL flake food suspension per day. The 1.5 mL flake food suspension contained 6.0 mg of dry solids. On the final day of the 10-Day test, percent survival of exposed H. azteca and C. dilutus was determined by first removing any organisms from the overlying water. The sediments were then rinsed from each of the test chambers into a 0.426 mm sieve using a gentle stream of post-carbon treated water. The contents retained in the sieve were rinsed into a polyethylene pan, placed on a light source, and searched for test organisms. Numbers of live and dead organisms found were counted and recorded. Organisms not found were recorded as dead; the organisms were assumed to have died early in the exposure and the remains had decayed. Growth of the exposed organisms was determined by dry weight. Surviving organisms were rinsed with deionized water, placed in pre-weighed aluminum pans, and dried at 60 °C for 24 hours. Organism weight was then determined to the nearest 0.01 mg. After dry weights were obtained, the C. dilutus test organisms were placed into a muffle furnace and ashed at 550°C for two hours. Mean ashed weights were then determined to the nearest 0.01 mg. Statistical analysis of the data was not conducted due to the clear homogeneity of data between the control sediments and the test sediments. The reference toxicant, sodium chloride, was used to monitor the sensitivity of each batch of test organisms and the precision of the testing procedure. A water-only 96-Hour Reference Toxicant Test was performed on the same batch of test organisms used in the sediment exposure. The resulting 96-Hour LC50 values were plotted to determine if the results were within prescribed limits (Appendix B). The resulting value for each test species was within the range of literature values reported for similar exposures.
3.0 RESULTS Test Acceptability Overlying water chemistry at test initiation and test termination for the H. azteca tests are provided in Tables 1 – 2; Tables 1 and 3 provide overlying water chemistry at test initiation and test termination for the C. dilutus tests. The overlying water quality measurements for both test species were within the acceptable limits according to EPA test protocol (i.e., daily mean temperatures were within 23+1 °C, dissolved oxygen

(DO) concentrations were maintained above 2.5 mg/L in the overlying water, and there were no variations greater than 50 percent in hardness and alkalinity). Ammonia concentrations did vary by more than 50 percent in each of the exposures; with the greatest increase observed in the reference sediment of the C. dilutus exposure (i.e., <0.01 to 0.8 mg/L). The highest recorded ammonia concentration in any of the exposures (i.e., 0.8 mg/L) was observed in Control A sediment of the C. dilutus exposure. In our best professional judgment, none of the observed ammonia concentrations were at a level to adversely impact the test endpoints of either test species. Daily dissolved oxygen and temperature results are provided in Appendix C. Both laboratory control treatments exceeded the minimum survival and growth requirements of the 10-Day test for both test species (80 percent survival and measurable growth for H. azteca [initial weight 0.01 mg]; 70 percent survival and final weight of at least 0.48 mg for C. dilutus). H. azteca Toxicity Test Results After the 10-Day exposure, percent survival of H. azteca in the laboratory control sediments A and B were 99 and 100 percent, respectively (Table 4). Percent survival in the test sediments was 92.5 percent in Sample RJ-195 and 100 percent in the Sample RJ-187. When percent survival of the control sediments was compared to the survival in the Reach J samples, no significant differences were found. Growth (measured as mean dry weight per surviving organism) in laboratory control sediments A and B were 0.09 mg and 0.08 mg, respectively. H. azteca growth in the two test sediments ranged from 0.07 in Sample RJ-195 to 0.08 mg in Sample RJ-187 sediment. There were no significant differences found upon comparing the growth in the control sediment to the test sediments. Raw test data for the survival and growth endpoints are contained in Appendix C. C. dilutus Toxicity Test Results Following the 10-Day C. dilutus exposure, survival in the laboratory sediments A and B were 99 and 85 percent, respectively (Table 5). Percent survival in the test sediments ranged from 94 percent in Sample RJ-195 to 99 percent in Sample RJ-187. When percent survival of the control sediments was compared to the survival in the Reach J samples, no significant differences were found. Growth (measured as mean ash-free dry weight (AFDW) per surviving organism) in the laboratory control sediments A and B was 1.25 mg and
ERM 4 Dow Chemical Company/0066953.0070/04/15/09
1.27 mg, respectively (Table 5). C. dilutus growth in the two test sediments ranged from 1.72 in Sample RJ-195 to 1.37 mg in Sample RJ-187. Growth in the Reach J sediments was found to be greater than that in the control sediments. Raw test data for the survival and growth endpoints are contained in Appendix C.
