EXECUTIVE SUMMARY

The U.S. Army Corps of Engineers, Chicago District is responsible for maintaining commercial navigation in the Calumet River and Harbor by periodic dredging to authorized depths. During the period from 25 August 2000 to 14 April 2001, the federal channel within the Calumet River was dredged and the dredged material was disposed of in the Chicago Confined Disposal Facility (CDF). Water and sediment samples were collected between 18 July 2000 and 27 April 2001 and analyzed to asses the impact of this dredging / disposal event.

The purpose of this report is to summarize the monitoring activities for the maintenance dredging of the Calumet River from 25 August 2000 to 14 April 2001 as part of compliance with Illinois EPA Water Pollution Control Permit number 1987-EA-2851 and Section 401 certification requirements.

The report contains the analytical results for the filter cell effluent (treated CDF discharge), total suspended solids monitoring at the dredging and rehandling areas and dredged sediment. Also included is a discussion relating to the potential for impact of the filter cell effluent on the Calumet River and an analysis of filter cell performance. In addition to the above, the water quality data in and around the CDF was analyzed in order to determine if the 2000/2001 dredging and disposal event or the CDF operation was adversely impacting water quality in Calumet Harbor.

Review of the analytical results showed that the treated effluent from the filter cells was below water quality standards and the treated effluent did not adversely impact Calumet River water quality. The filter cells were also effective in removal of the suspended solids below the design level indicated in the Final Environmental Impact Statement. During monitoring around the dredge or rehandling areas, some of the TSS concentrations were above background levels, but the increase was localized and short-term.

The results of these analyses of water quality data indicated that there is no qualitative evidence that indicates that the CDF operation or the 2000/2001 dredging and disposal event has adversely impacted water quality in Calumet Harbor. In addition, the monitoring of the 2000/2001 maintenance dredging operation was in compliance with the Illinois EPA Water Pollution Control Permit and Section 401 certification requirements.

1.0 Purpose

The U.S. Army Corps of Engineers, Chicago District (Corps) is responsible for maintaining commercial navigation in the Calumet River and Harbor by periodic dredging to authorized depths. Because the sediment in the Calumet River is contaminated, the dredged sediment is placed in the Chicago Area confined disposal facility (CDF). There are two monitoring programs associated with this activity. Routine monitoring of the water quality in and around the CDF is conducted on a tri-annual basis. Additional monitoring occurs during maintenance dredging operations. This additional monitoring involves weekly sampling of the water quality in and around the CDF as well as trubidity around the dredging and unloading areas. In addition, suspended solids levels are monitored in the effluent from the filter cells and the discharge area of the Calumet River.

The purpose of this report is to addressee the maintenance dredging of the Calumet River during the period between 25 August 2000 and 14 April 2001. The results and analysis of the monitoring done before, during, and after the dredging event is provided in Sections 4 and 5. The sample collection period was from 18 July 2000 through 27 April 2001

2.0 Background

The Chicago Area CDF is a facility for the disposal and containment of polluted dredged materials from deep-draft federal navigation projects in Chicago, Illinois. The CDF was constructed by the Chicago District in 1982-1984 in Calumet Harbor, south of the Calumet River entrance channel and adjacent to the Chicago Port Authority-owned Iroquois Landing. The CDF is an in-water diked facility and triangular in shape. Dikes form two of the walls and Iroquois Landing forms the third. The facility is about 43 acres in area and has a capacity for approximately 1.3 million cubic yards of dredged materials. This facility was constructed and is operated and maintained by the Chicago District under authority of PL 91-611, Section 123.

The Chicago Area CDF has been previously used for six dredged material disposal operations since its construction. The seventh dredging event, which is discussed in this report, was the maintenance dredging of the Calumet River. The dredging occurred from 25 August 2000 to 14 April 2001. 205,424 cubic yards were dredged by Lake Michigan Construction of Holland, Michigan, from the locations shown in Figures 1a through 1g. Material was dredged mechanically using an enclosed bucket, transported in scows and disposed of in the CDF. A summary of the seven dredging events which have been disposed of in the CDF is outlined in Table 1. All the dredging events except for the fifth were conducted by the Corps; the fifth event was conducted by KCBX Terminals Company.

3.0 Introduction

During the period of 25 August 2000 through 14 April 2001, various locations within the Federal Channel of Calumet River were dredged and the dredged material was disposed in the CDF. During a dredging event, the CDF is routinely monitored as part of compliance with Illinois EPA Water Pollution Control Permit number 1987-EA-2851 and Section 401 certification requirements. A report summarizing the monitoring activities conducted for the dredging event is routinely submitted to the Illinois EPA.

Sections 4 and 5 present a summary of the 2000/2001 dredging event. Section 4 discusses the sampling program used to document the water quality before, during, and after dredging. Section 5 contains the analytical results for the filter cell effluent (treated CDF discharge), total suspended solids monitoring at the dredging and rehandling areas, and dredged sediment. Also included in this section is a discussion relating to potential for impact of the filter cell effluent on the Calumet River and an analysis of filter cell performance. A graphic evaluation of the 2000/2001 dredging event is presented in Appendix B. The report is summarized in Section 6.

3.1 Description of Dredging and Rehandling Operations

Dredged material was loaded into scows using an enclosed clamshell bucket. The scows were transported by tugboat to the rehandling area along the eastern dike wall of the CDF between stations 16+00 and 23+00. Dredged material was removed from the scows by enclosed clamshell bucket and transferred to the CDF by a hopper located on the dike wall and a sluice with a drop section.

The inside of the CDF forms a ponded area of approximately 30 acres, with water depths on average of approximately 10 feet. During the disposal/rehandling operation, water is pumped from the southern end of the CDF to filters located by the Calumet River approximately 3,000 feet west of the CDF. The CDF ponded water is clarified by settling in the CDF pond followed by gravity filtration and discharge to the Calumet River.

The hours of operation for a particular dredging event depend on the completion schedule and the pieces of equipment and crew members that the dredging company has available. In the case of Lake Michigan Contractors, the dredging event was split into two periods, 25 August 2000 to approximately 4 November 2000 and 22 January 2001 to 14 April 2001. With the exception of down time for equipment maintenance and repair and inclement weather, the dredging event was conducted for a full twenty-four hours per day over a seven-day week. The operation was temporarily halted on several occasions because of the weather conditions. In addition, the operation was halted from around 4 November until 22 January 2001, due to winter weather conditions.

4.0 Sampling Program

A sampling program was established to document the water quality before, during, and after dredging. In addition, sediment samples were collected that characterized the material to be dredged. Monitoring was conducted at the stations shown in Figure 2 to evaluate the following specific tasks:

a. Compare the water quality of the treated effluent from the CDF to applicable water quality standards (Station 3, Filter cell effluent).

b. Document the chemical characteristics of dredged material disposed in the CDF (Sediment sample).

c. Document and review the localized effect of the dredging and rehandling operations on the water quality in Calumet River and Harbor, respectively (Total suspended solids monitoring around the dredge and rehandling operations).

d. Compare the river background to a downstream sample of the Calumet River to determine if there is an effect from the discharge of the filter cells (Stations 4A and 4B).

10

Figure 2: Sampling Locations during dredging events

e. Check the performance of the filter cells in retaining solids (Station 2, Filter cell influent and Station 3, Filter cell effluent).

f. Determine the effect of the dredging event on the water quality of Calumet Harbor.

g. Evaluate the short-term impact of the CDF operation on Calumet Harbor water quality.

The samples were collected over the period extending from 18 July 2000 to 27 April

2001 by Tri-Matrix Laboratories of Grand Rapids, Michigan. This included the before, during, between and after dredging time periods. Samples were collected at two sampling frequencies. Before and after dredging samples were collected twice a week, during and between dredging samples were collected once a week except for a single interval of twice-a-week sampling. Table 2 lists the sediment parameters, Table 3 lists the water parameters, and Table 4 outlines the sampling analysis and frequency.

The sampling dates are shown on the calendar in Table 5. The before dredging

samples were collected from 18 July 2000 through 28 July 2000. The during dredging samples were collected from 25 August 2000 through 14 April 2001, with a major stop in dredging activities, from approximately 4 November 2000 until 22 January 2001 due to winter weather conditions. Samples were collected between dredging events from 20 December 2000 until 15 January 2001. The after dredging samples were collected from 18 April 2001 through 27 April 2001. Samples were collected over a period of ten months. The laboratory analysis, submitted by Tri-Matrix, is included as Appendix D and contains the analytical results, field sampling and laboratory analysis quality control measures, and field sampling logs.

The water quality samples collected within and around the CDF were as follows: CDF-001, CDF-002 and CDF-003 were collected from the CDF pond at 3 sample locations, taken at one third of the depth at each location; samples CH-18-81, CH-19-81, and CH-20-81 were collected from the three shallow wells installed in the landing

15

adjacent to the CDF; RIV-001, RIV-002 and RIV-003 were samples collect around the effluent discharge of the filter cell, at one third the depth; ND-COMP-001, ND-COMP-002 and ND-COMP-001 were each composite samples collected in Calumet Harbor, at one third of each depth; and Stations BACK-001, BACK-002 and BACK-003 were samples collected in Calumet Harbor at one third each depth, which served as background samples for the harbor. The previous samples were collected before, during, and after dredging. CH-00-02 and CH-00-03 were collected from the filter cell influent and effluent, respectively, and were collected only during dredging. To monitor the dredging and rehandling operations, samples were collected around the dredge and rehandling areas and analyzed for turbidity. Lastly, a weekly sample of the dredged sediment was collected from the scow during dredging.

The Quality Assurance/Quality Control (QA/QC) measures for this project applied to both sample collection and laboratory analytical testing. The field sampling QA consisted of collecting rinsate samples and collecting a weekly field replicate sample. The laboratory QC samples consisted of matrix spikes and matrix spike duplicates, method blanks, surrogate spikes, and laboratory control samples.

5.0 Discussion of Analytical Results

This report was written to document and analyze the 2000 / 2001 maintenance dredging of the Calumet River. The seven objectives (a through g) of the sampling program listed in Section 4 will be discussed in Section 5. The discussion includes a comparison of the analytical results to water quality standards, background levels, or previous dredging operations.

The laboratory analysis was performed by Tri Matrix of Grand Rapids, Michigan. The analytical results and the laboratory QC sample results are included in Tri-Matrix’s report provided in Appendix D of this report. Summary tables of the laboratory results are included in Appendix A, graphical analysis of these results are included in Appendix B and two quality assurance reports are included in appendix C.

5.1 Treated Effluent from the CDF (Filter Cell Effluent) When dredged material is placed in the CDF, water is pumped from the CDF

pond through one of two redundant filter cells. The treated effluent is then discharged into the Calumet River at a point approximately 3,000 feet downstream from the harbor mouth. Weekly effluent samples (CH-00-03) were collected during dredging, whenever pumping operations from the CDF were conducted. In general pumping operations were conducted only during unloading operations into the CDF, however weather conditions throughout the dredging period often prevented unloading of sediment from barges. Collection of a composite sample was accomplished using an automatic-timed sampler. Sampling frequency was set at 10ml every hour such that a 5 gallon jar was filled in the course of a week. This container was mixed prior to sample collection such that a sample was taken to represent the water quality for a weekly period. Where pumping operations

16

were not continuous during the week proceeding collection, the sampling frequency was adjusted in the morning of collection, to every ten minutes, such that a representative sample could be collected by the end of the day.

The mean values of the effluent samples are presented in Column 2 of Table 6. The general use water quality standards (Column 3) and means of the CDF pond samples (Column 1) have been included for purposes of discussion. The treated effluent is compared to general use water quality standards as a point of reference. The CDF pond samples are shown to compare the water quality of the untreated pond to treated effluent.

Inclusion of the ‘<’ symbol indicates that at least one non-detect was included in calculating the mean. (2) These are the acute water quality standard from Subpart B (Title 35, Subtitle C, Chap 1, Section 302.208). (3) Standard is based on hardness concentration of 157 mg/l.

17

Section 302.208 of Subpart B establishes an acute and chronic water quality standard for the following parameters: arsenic, cadmium, chromium, copper, mercury, lead, and cyanide. Because dredging has a short-term impact on water quality (USACE, 1988), it was decided that the acute standards are more applicable than the chronic ones. In addition, chronic standards are not applied to mercury or lead as stated in Subpart 302.208(d). All the tables in this report will present the acute standards, as presented in column 3, for comparison to the water quality sample results.

As seen from Table 6, in general there is a reduction in contaminant concentration between the samples collected from the CDF pond and the samples collected at the discharge point. Because the mean concentrations are calculated using the detection limit for samples where no concentrations were detected, the concentrations are conservative for parameters where non-detects were observed.

As shown in Table 6, all of the effluent parameters met the water quality standards. Since the effluent concentrations were less than the water quality standards, a mixing zone was not applied.

5.2 Sediment Quality

For the entire dredging event, sediment samples were collected directly from the scow at the station where the dredge was located. The analytical results for the four sediment samples are summarized in Table 7a and 7b.

An average for each parameter was calculated for the eighteen sediment samples and is shown in Table 8. Also included in Table 8 is the minimum, mean, and maximum results of the sediment analysis for the recent dredging event and the past five dredging events contracted by the Corps (1984, 1985, 1986, 1989 and 1994). In the last column, the table displays the overall maximum, mean, and minimum from all the combined sampling events. The mean value is calculated from the six means of each sampling event. The number of sediment samples collected for each dredging event varied from 4 to 18 as shown in the last row of the table. The number of samples was dependent on the length of the dredging operation.

The sediment chemistry in the Table 8 characterizes the sediment that was placed in the CDF during the last six dredging operations. Maintenance dredging of the river occurred in the shoaled areas so the sediment characteristics shown in Table 8 would have been from various locations along the river. Some variation in the data is introduced due to using multiple laboratories, analytical methods and sample collection techniques.

5.3 Turbidity Monitoring During Dredging

To assess the contractor’s operating performance during dredging and rehandling, water samples were collected to measure the Turbidity around the dredging area and rehandling area. Three sampling locations were specified at each of the two areas and samples were collected at two depths (at a few feet below the water surface and at mid-depth). Samples were collected once a week for four weeks and analyzed for total suspended solids using method 160.2 from EPA-600/4-79-020. The sampling locations for both the dredging and rehandling areas are shown in Figure 3.

5.3.1 Dredging Area Turbidity Monitoring

The three sampling stations around the dredging operation were: 100 feet upstream, 100 feet downstream, and 500 feet downstream of the centerline of the dredge. The upstream samples were collected to establish background suspended solids concentrations in the river. As the dredge was relocated to different stations along the Calumet River, the sampling locations remained the same in relation to the dredge and the flow of the river.

Generally, all three samples were collected one after the other within one-half

hour of each other and after the harbor and river water quality samples were collected. As reported by the Metropolitan Water Reclamation District, the annual average flow through the O’Brien Lock and Dam for the period of record from 1983 to 1992 is 250 cubic feet per second. The lock is at the downstream end of the Calumet River and is an indication of the current in the river, because the lock controls the flow. Based on a channel cross-section 300 feet wide by 30 feet deep, the average current would be 0.03 ft/sec.

The analytical results are summarized in Table 9. Means were calculated for each depth for the three samples collected around the dredge. Figure 4 depicts the means at each sampling location. At 100 feet downstream, the mean surface and mid-depth Turbidity concentrations were higher (ranging from 27-30.5mg/l) than that of the mean upstream samples (ranging from 21.6-23.8mg/l), which is considered the background for the river. At 500 feet downstream, the mean suspended solids concentration of both surface and mid-depth samples were similar to background levels (ranging from 20.9-23.9 mg/l).

The nature of the dredging operation creates resuspension of solids in the water column which causes increased suspended solids. The resuspension is a localized, short-term impact which decreases as the distance from the operation increases, as evidenced by these monitoring results. Table 9.

5.3.2 Rehandling Area Turbidity Monitoring

The rehandling area was located along the CDF dike wall between shallow wells 7 and 9. Water samples were collected at three sampling points within approximately 100 ft of the scow. The three samples were collected one after the other within one-half hour and along with the harbor water quality samples. Table 10 is a list of the means of the rehandling area Turbidity samples. The total suspended solids concentrations around the rehandling area averaged between 6.2 to 11.4 mg/L. Table 10. Turbidity Monitoring Results Around the Rehandling Area

As would be expected, the mean suspended solids concentrations around the rehandling area were less than those around dredge because the clamshell bucket did not enter the water column. Figure 5 shows the means of the TSS concentrations around the rehandling area on a bar graph.

Some spillage occurred at the rehandling area as the sediment was removed from the barge and placed in the hopper on the dike wall. In order to minimize the spillage, a spill pan was placed on the rehandling barge to catch spills from the bucket.

5.4 Calumet River Sampling

The Calumet River was sampled at three points around the filter cell effluent discharge point to determine if the effluent had an impact on the river. RIV-001 was collected 200 feet upstream of the discharge point, RIV-002 was collected at the discharge point and RIV-003 was collected 200 feet downstream of the discharge point.

5.4.1 Calumet River Sampling During Dredging

The only time that water is pumped from the CDF and discharged through the filter cells is when dredged material is placed in the CDF. A total of 21 samples were collected from each river location during dredging. The mean concentrations during dredging were calculated for each of the three river locations and are presented in Table 11. The general use water quality standards and means of the filter cell effluent have been included in Table 11 for discussion.

No Cadmium, Mercury nor Cyanide were detected in either the river or the filter cell effluent. All the other parameters were below water quality standards. In general contaminant concentrations measured in the filter cell effluent were slightly higher that river concentrations, but well below water quality standards.

5.4.2 Calumet River Sampling Before and After Dredging

Samples were collected at RIV-001, RIV-002 and RIV-003 for the two weeks before dredging and the two weeks after dredging as well as during dredging. These samples were collected to establish the water quality of the river with no discharge from the filter cells. Table 12 displays the means of the river samples collected before during after dredging.

Table 12 provides a comparison of water quality upstream and downstream from the effluent discharge before, during, and after dredging. Cadmium and Cyanide were not detected in the river throughout the sampling period. Concentrations of Arsenic Chromium, Mercury, TKN and Phosphorus were measured close to the detection limit. However, Concentrations of Copper, Manganese, Nickel, Lead, Zinc Total Dissolved Solids, Total Suspended Solids, Hardness and pH were measured higher during and after dredging.

The solubility of oxygen in water varies inversely with temperature. At the water

temperatures measured in the field, the concentration of oxygen at saturation could range from 12 to 14 mg/l. As shown in Table 12, mean dissolved oxygen (DO) concentrations increased during dredging as the water temperature decreased.

5.5 Filter Cell Performance as Measured by Solids Removal

The ability of the filter cells to reduce the total suspended solids in the effluent is a measure of their performance. According to the Final Environmental Impact Statement issued for the construction of the CDF, the filter cells were designed to reduce the suspended solids in the discharge to at least 15 mg/L (USACE, 1982). The Illinois Environmental Protection Agency’s water quality standard for total suspended solids in the Lake Michigan Basin is also 15 mg/l. Table 13 summarizes the suspended solids concentration in the filter cell influent and effluent during the dredging period. The effluent did not exceed the 15 mg/L design concentration in any of the samples. Table 13. Total Suspended Solids Concentrations and Filter Cell Efficiency

CH-00-02 CH-00-03 Sampling Filter Cell Filter Cell Efficiency

Date Influent Effluent (%) (mg/l) (mg/l)

An efficiency can be calculated for 16 September 2000 because both of the

samples had a TSS concentrations greater than the detection limit. Because the filter effluent sample was below the detection limit on six other occasions, the calculated efficiencies were between >83% and >98%. No Influent samples were collected on 26

29

September 2001 and 3 March 2001, due to halted pumping operations into the filter cell. TSS levels on 20 February 2001 were measured at 2 mg/l at both the influent and effluent. The filter cell efficiency is a function of the influent and effluent TSS concentrations.

6.0 Report Summary During the period of 25 August 2000 through 14 April, various locations within the Federal Channel of the Calumet River were dredged and the dredged material was disposed in the CDF. As part of compliance with Illinois EPA Water Pollution Control Permit number 1987-EA-2851 and Section 401 certification requirements, this report summarizes the monitoring activities conducted for the dredging event. The following conclusions were reached upon review of the analytical data: 1. The treated effluent was below water quality standards and the discharge did not

indicate an adverse impact on Calumet River water quality as discussed in Sections 5.1 and 5.4, respectively.

2. TSS concentrations did not differ significantly between upstream and downstream monitoring stations around the dredge.

3. Although TSS concentrations increased around the rehandling area, the increase was localized and short-term. The increased TSS concentrations are likely to be caused by the washing of eroded fines from the dike wall in conjunction with the rehandling operation. The rehandling TSS concentrations were less than the TSS concentrations around the dredge.

4. The filter cells were effective in removal of the suspended solids.
