1.4 SYSTEM OPERATION

1.4.1 Influent Characteristics

The characteristics of the water to be treated are from samples collected from the CDF cells since 2013, which are attached at the end of this specification in Table 1 "IHC Pond Sampling Results-WWTP". The range of concentrations presented in the table is expected to be representative of the water to be treated. However, concentrations outside the range presented on Table 1 can also potentially occur. Table 2 summarizes the parameters that are on the NPDES permit along with the minimum and maximum concentrations observed in the CDF pond from 2013 through 2021.

Water will be extracted from the IHC CDF east or west dredged material disposal cells as directed by the COR via the two (2) decant structures for treatment. Water must be withdrawn in a manner that minimizes sediment resuspension and the inclusion of solids in the water stream, and must also be withdrawn in a manner that prevents a visible sheen or separate phase oil from entering the water stream.

The Contractor shall collect one sample from each cell of the CDF monthly during water treatment. Collect one sample from each cell of the CDF monthly when the plant is not operating, unless the ponds are frozen.

Coordinate so that the monthly samples prior to each treatment season shall be collected 2 weeks before treatment starts, for every treatment period.

The samples shall be collected from the pond at mid-depth, from a location within the pond with water depth of at least 2 feet. The samples can be collected from the decant structures when the decant structures are accessible. After the center dike submergence and the CDF becomes one pond, collect one sample from the CDF near the point of water withdrawal for treatment. The samples shall be analyzed for all parameters on Table 1.

All pond sampling results shall be presented in the Quarterly Data Report.

In addition, laboratory pond sampling data shall be provided to the Government as they are received from the laboratory as draft submittals for information only. Data collection, analysis, review, validation, documentation shall be in accordance with 01 35 45 CHEMICAL DATA QUALITY

CONTROL.

1.4.2 Wastewater Treatment Plant Flowrate and Operation Period

The estimated maximum volume of water for treatment is 70 to 80 million gallons per year. A more typical volume of water requiring treatment is 30 to 50 million gallons per year. In the past, annual treatment duration ranged from 3 to 8 months, and annual treatment volumes ranged from 30 to 80 million gallons. The wide range of possible water treatment volumes is due to a variety of factors: precipitation volume, whether dredging will occur requiring capacity in the CDF, the progress of the CDF dike expansion resulting in increase in CDF capacity, the frequency of water treatment.

Water will accumulate in the CDF and the Government will order water treatment as needed. Water treatment can be ordered from either cell of the CDF. A lead time of 30 days will be given to the contractor to mobilize and be ready for treatment after a task order is accepted. Water treatment may be required at any time during a year, and therefore, the treatment plant shall have the capability of operating during the winter season.

The NPDES permit flow rate is 0.6 million gallons per day and contaminant mass limits in the NPDES permit are based on this flow rate. Larger flow rates may be allowed in the future if mass limits are not exceeded based on quality of the treated water. The contractor shall size the treatment plant to efficiently remove water from the CDF to not delay dredging if CDF capacity is required to hold dredged material.

1.4.3 Effluent Characteristics

The Contractor is required to size, install, and operate the appropriate equipment in order to comply with the discharge requirements of the NPDES Industrial Discharge Permit obtained by United States Army Corps of Engineers, Chicago District (USACE). A copy of the NPDES permit is included as an Attachment to Section 01 57 20.02 03 ENVIRONMENTAL

PROTECTION FOR INDIANA.

1.4.4 Extraction of Water from CDF and Return Water to CDF

The Contractor shall provide all equipment, pumps, piping, and appurtenances in order to deliver water from the decant structures to the treatment plant and return water/backwash from the plant to the CDF . When extracting water from the CDF for treatment, the Contractor must not pump directly from the CDF (i.e., CDF effluent must be pumped from the existing decant structures), except as described below.

The CDF is currently undergoing an expansion where the height of the exterior dikes of the CDF will be increased, potentially in two stages. The initial dike height increase will be 3 feet, and the second dike height increase will be an additional 8 feet for a total increase of 11 feet. The possibility of the dike expansion occurring in one stage or two stages is dependent on availability of funding which is unknown at the current time.

An impact of the dike expansion on wastewater treatment will be the removal and re-installation of the WWTP piping as required. Piping that is placed over the CDF dike will require removal/reinstallation to accommodate the dike expansion. Piping that is placed on top of the dike can be assumed to require three installation/removal (at current height, at 3-foot increase, at 11-foot increase) in addition to installation/removal that may be determined by the contractor as needed. Piping that is not installed on the dike can remain during the contract. All piping will be removed from the site at the end of the contract.

The east cell decant structure will be raised along with the dike raise at the 11-foot raise. The west cell decant structure will not be raised and will remain the current height. As required, the Contractor shall coordinate with the dike construction contractor for access to the decant structures.

The west decant structure is accessed by the CDF center dike via the decant structure bridge. The center dike will not be raised when the exterior dikes are raised although the ramp between the expanded dike crest and the west decant structure will be modified during dike expansion to maintain interim access to the west decant structure. The west decant structure will not be accessible via the bridge and center dike after the center dike is eventually submerged by increasing impounded sediment and water levels after future dredging events. After the center dike submergence, the CDF will essentially become one pond. The Contractor shall extract water via the east decant structure when there is no construction work at the east decant structure. During the east decant structure construction, the Contractor may extract water directly from the CDF.

The Contractor shall coordinate with the COR when determining the location for installing the piping between the CDF cells and the treatment plant.

The Contractor is responsible for sizing the equipment, pumps, piping, etc., to be compatible with the proposed operations. Exposed (above ground) piping extending beyond the CDF interior, including piping over the dike, must be double-walled. The Contractor may place supporting equipment on the decant structure bridges so long as access to the structure is not impeded.

The decant structure bridge grating is galvanized steel with welded rectangular grating conforming to standards of National Association of Architectural Metal Manufacturers. Heavy duty rectangular steel bar gratings have bearing bars spaced at a maximum of 15/16-in and crossbars are spaced at a maximum of 2-in. Grating material conforms to ASTM A 36/A 36M. Grating was sized for AASHTO H20-44 wheel loading of 16-k per wheel at 14-ft on center and also for one concentrated load of 61,000-lbs acting on the structural steel to accommodate outrigger loads. Bridge has a maximum deflection of L/240. Slip resistance requirements exceed both wet and dry a static coefficient of friction of 0.5 as tested in accordance with ASTM F 1679A. Storage of equipment on the decant structure bridge shall be subject to approval by the Government with regards to weight and loading on the bridge.

Return piping from the treatment plant to the CDF (for backwash water and for treated water not meeting discharge criteria) shall be a floating pipe.

Treatment plant return piping shall discharge to the CDF west cell. Return piping shall have a flow dissipator at the discharge to minimize disturbance of sediment in the CDF ponds during discharge.

The Contractor shall not excavate through the dike to place the piping between the CDF and the treatment plant. Consequently, the piping between the CDF and the treatment plant shall have to cross the road at the top of the CDF dike. The Contractor shall provide protection for the piping from traffic at the road(s), and the piping shall not interfere with traffic on the road(s). Protection of the conduit, associated with normal operations, shall be the responsibility of the Contractor. The conduit shall be free of leaks at all times.

1.4.5 Disposal

The sludge generated during the treatment process by the WWTP will be disposed within the CDF. All processing water such as water used during the start-up period, backwash water during system operation, etc., shall be discharged to the CDF. Material such as activated carbon, ion exchange media will be regenerated or disposed offsite as appropriate. Water treatment chemicals or spent media, or other leftover materials used by the contractor at the IHC CDF must be disposed of offsite-consistent with all Federal, State, and Local requirements. Other waste generated such as filter membranes, filter media, and decant structure spent oil absorbent booms will be transported off Government property and disposed of in accordance with Federal, State, and local requirements. The Contractor shall verify that the selected transporters and disposal facilities have the necessary permits and licenses to operate.

1.4.6 Government Provided Facilities

The facilities provided at the CDF for the WWTP are specified in 01 10 00 GENERAL PROVISIONS. The area reserved for the wastewater treatment plant is located on the south side of the facility.

Water to be treated will be drawn from existing decant structures, and will be pumped to the wastewater treatment plant by the Contractor, except as described in these specifications. The location of the area for the package WWTP is shown in the drawings The Contractor shall prepare the designated area as needed to install the treatment plant.

1.4.7 Water Treatment Additives

The site NPDES permit does not include approval for any water treatment additives. If the Contractor elects to use water treatment additive(s), the contractor must apply for and obtain approval from IDEM prior to use of the additive(s) in accordance with the NPDES permit.

PART 2 PRODUCTS

2.1 DECANT STRUCTURE PUMPING SYSTEM AND DISCHARGE LINE

The Contractor is responsible for sizing and selecting the appropriate material for all pumps, wiring, controls, valves, and appurtenances to be compatible with the proposed operation and contaminants at the site.

Contractor shall select the appropriate pipe size(s). Piping extending beyond the CDF interior, including piping over the dike, must be double-walled. A secondary containment berm surrounding the water treatment equipment is acceptable as an alternative to double walled piping. Piping outside the containment berm shall be double-walled. Due to the contamination and unknown obstructions in the original site soil, excavation into the original site soil must receive prior approval from the

COR.

2.2 FLOWMETERS

The Contractor shall provide a tamper-proof totalizing flowmeter on WWTP influent line, and on the WWTP effluent discharge line to indicate the instantaneous flow rate and to record the total volume of water entering and discharged from the treatment plant. The flowmeters shall have an accuracy of +/- 0.5%. The flowmeters shall have data logging capability.

The reading on the effluent flowmeter will be used for payment. The purpose of the influent flowmeter is to confirm quantity treated by the treatment plant. The flowmeters will be placed in an area so that they can be read by a representative of the Contracting Officer at any time. Calibrate the flowmeters prior to each water treatment season, and provide calibration reports in the Startup Reports.

2.3 WWTP EFFLUENT DISCHARGE LINE

Contractor shall furnish, install, and protect a continuous discharge conduit that provides positive drainage from the treatment facility to Lake George Canal. The location of the discharge line shall be coordinated with the COR. The Contractor shall provide any protection and support of the conduit as appropriate. The Contractor is responsible for sizing the conduit to be compatible with the proposed operations. The conduit shall be free of leaks at all times, and shall extend to the CDF south cutoff wall at all times, with no discharge on the land side of the cutoff wall.

The discharge shall not be through the cutoff wall. There is a gravel access road and drainage ditch on the south side of the site between the treatment plant pad and the south cutoff wall. The discharge line shall not interfere with traffic on this access road or capacity of the ditch.

Protection of the conduit, associated with normal operations, shall be the responsibility of the Contractor. Contractor shall determine the need for an air release. Discharge velocity in the pipe shall not exceed 6 feet per second. The conduit shall maintain a sufficient slope to maintain a downhill discharge and prevent ponding. Lower the discharge pipe to minimize spraying at the exit to the Canal. The WWTP effluent discharge line does not require double walled piping. The effluent discharge line shall be removed at the end of the contract.

PART 3 EXECUTION

3.1 FIELD QUALITY CONTROL

3.1.1 Preoperational Test

Inspect, operate, and test all equipment before startup.

3.1.1.1 Tests

Tests shall include but not be limited to the following:

a. Soundness (without cracked or otherwise damaged parts).

b. Completeness in all details, as specified.

c. Correctness of setting, alignment, and relative arrangement of each component.

d. Verification of proper operation for all system components.

3.1.1.2 Preoperational Investigation and Test Report

Submit the Preoperational Test Report in the water treatment Startup Report.

Document inspections, operations, adjustments, and tests performed and indicate whether they were acceptable or not. For unacceptable items, describe corrective action taken. Include detailed descriptions of points inspected, tests and adjustments made, and quantitative results obtained.

3.1.2 Electrical Continuity and Insulation Resistance Tests

Perform wire and cable continuity and insulation tests before the conductors are energized. Perform continuity test to insure correct cable connection (i.e., correct phase conductor, grounded conductor, and grounding conductor wiring) end-to end as appropriate. Repair and re-verify any damages to existing or new electrical equipment resulting from mis-wiring.

3.2 WWTP STARTUP

Startup Testing will be done prior to the initial operating period of the WWTP, and also to every operating period if the previous operating period had ended more than 6 months previously. The results of the startup testing will be included in the Startup Report.

3.2.1 Clean Water Test

Once the treatment plant equipment has been installed and piped, the Contractor shall perform a clean water test using potable water from the site. This test will be performed to demonstrate that there are no leaks in the equipment or piping and that all gauges, sensors, pumps, and alarms are working properly. The Contractor shall notify the Contracting Officer at least 2 days before the test is performed. The clean water test shall be performed at the treatment plant design flow rate and shall be for a period of time sufficient to prove-out all equipment and controls.

Adjustments will be made and the tests repeated, as necessary, until satisfactory performance is achieved. The clean test water may be discharged to the Lake George Branch in compliance with the NPDES permit requirement. Alternatively, the clean water may be discharged to the CDF cells per USACE direction.

3.2.2 Initial Treatment/Startup Test

Once the system has been proven out by the clean water test, the system will be tested by pumping and treating water from the CDF. During the initial treatment testing, influent and effluent grab samples will be collected daily and analyzed for all required parameters. The samples will be analyzed by a certified laboratory on a 24 hour turn around time. The system will be considered fully operational if the effluent samples meet the NPDES permit requirements for 2 consecutive days. If the first test passes and the second test fails, the requirement is to start over until two consecutive tests (i.e., samples from two consecutive days) pass all NPDES permit limits. The initial treatment test shall be performed at the treatment plant design flow rate and shall be for a period of time at least equivalent to the 2 consecutive day period where effluent samples that meet NPDES permit requirements are collected. Adjustments will be made and the tests repeated, as necessary, until effluent samples meet all NPDES permit requirements for two consecutive days. During the initial treatment testing, the effluent will be discharged to the CDF. Inform the Government when startup testing is initiated, as the Government may choose to observe the startup testing sample collection.

Results from the initial treatment/startup test will be reported in the Startup Report. The report shall include the laboratory results, tabulated sampling data, and a record of operating parameters and adjustments made if required. Documentation of successful startup as described above will be required in the startup report.

3.3 ROUTINE OPERATION

3.3.1 Influent Sampling

During treatment plant operation, collect WWTP influent samples on the same schedule as the effluent sampling for NPDES reporting, to be sent for offsite laboratory analysis for all required parameters on the NPDES permit. Samples shall be collected from the influent line into the treatment plant. The purpose of influent sampling, along with the "real-time" influent sampling described below, is to understand variability in the influent, and/or to determine whether additional treatment is needed. The samples will be analyzed on the same turn around time as the effluent samples for NPDES permit reporting.

During treatment plant operation, collect daily WWTP influent samples for Ammonia and Total Suspended Solids analysis. The analyses shall be performed in "real-time" to inform the treatment plant operation.

Typically, ammonia levels in the CDF ponds have been higher in the fall through spring. Perform daily influent ammonia sampling when ammonia treatment is required. Influent ammonia sampling can provide information on whether ammonia treatment is required, and/or the level of treatment required. During summer water treatment, after it can be demonstrated that ammonia levels are low enough to not require treatment (7 days of treatment plant influent ammonia levels below NPDES discharge limit with no treatment), daily sampling for ammonia can halt. The contractor shall propose the methodology for measuring Ammonia to a detection limit below 1 mg/L, and which can provide results in "real-time" (less than 1 hour).

Total suspended solids (TSS) is a highly variable parameter in the CDF water, and can vary based on wind conditions, water volume in the CDF, precipitation, season of the year, presence of vegetation/algae, among other factors. Because TSS levels can change quickly, and because TSS can be an indication of other regulated parameters such as mercury and other metals, it is critical to sample WWTP influent daily for TSS during treatment. Daily TSS sampling can provide information on the level of treatment that is required. The contractor shall propose the methodology (Standard Method 2540D or equivalent) for measuring TSS levels which can provide results in "real-time".

The contractor shall determine a sampling schedule to be compatible with the treatment schedule/duration that complies with the requirements of this specification.

All influent sampling results (laboratory and real-time) shall be presented in the Quarterly Data Report in tabulated form. In addition, laboratory influent data shall be provided to the Government as they are received from the laboratory as draft submittals for information only. Data collection, analysis, review, validation, documentation shall be in accordance with

01 35 45 CHEMICAL DATA QUALITY CONTROL.

3.3.2 Effluent Sampling

The Contractor shall collect effluent compliance samples at the frequency indicated in the NPDES permit. The samples will be analyzed by a National

Environmental Laboratory Accreditation Program (NELAP) approved laboratory (www.epa.gov/nelac/nelap.html) and the results reported to the Contracting Officer within 1 week of sampling. The results of the analysis will be compared to the NPDES permit discharge requirements. If a sample result indicates a compound concentration exceeds the discharge limit, the Contracting Officer shall be notified immediately and the cause of the exceedance shall be determined and rectified. Additional samples will be collected to confirm compliance with the discharge requirements. The Contractor shall also follow all protocols for reporting upsets to IDEM, as detailed in the NPDES permit. The results of the sampling and a summary of the corrective action will be included in the following month's Discharge Monitoring Reports and Quarterly Data Report.

The Contractor shall collect daily WWTP effluent samples for Ammonia and Total Suspended Solids analysis. The analyses shall be performed in "real-time" to inform the treatment plant operation.

Daily ammonia effluent sampling shall be conducted when daily ammonia influent samples are collected. Requirements for effluent ammonia sampling and analysis are the same as for the influent sampling.

The Contractor shall collect daily WWTP effluent samples for TSS analysis.

Requirements for effluent TSS sampling and analysis are the same as for the influent sampling.

If the daily effluent Ammonia or TSS sampling result exceeds the NPDES permit limit, discharge of treatment plant effluent to the Canal will cease immediately. Discharge to the Canal can resume when the daily effluent sampling passes the NPDES permit limit for the failed parameter as indicated by the "real-time" analysis, and confirmed by laboratory results.

The contractor shall determine a sampling schedule to be compatible with the treatment schedule/duration that complies with the requirements of this specification. Effluent testing for NPDES permit reporting shall be a methodology that is approved by IDEM for wastewater discharge testing.

All effluent sampling results (laboratory and real-time) shall be presented in the Quarterly Data Report. In addition, laboratory effluent data shall be provided to the Government as they are received from the laboratory as draft submittals for information only. Data collection, analysis, review, validation, documentation shall be in accordance with 01 35 45 CHEMICAL
