For further information. please call Leslie Lowry at 217/782-0610. The applicant is engaged in operating a hotel and condos (SIC 7011). Plant operation results in an average discharge of 19.7 MGD of non-contact water. unused river water, and strainer backwash from outfall 001 and an intermittent discharge of stormwater runoff from outfall 002. Public Notice/Fact Sheet -- Page 2 -- NPDES Permit No. Application is made for existing discharges which are located in Cook County. Illinois. The following information identifies the discharge point. receiving stream and stream classifications: Stream Integrity Outfall Receiving Stream Latitude Longitude Classification Rating 001 Chicago River 41" 53' 19" North 87? 37' 33" West General Use 002 Chicago River 41? 53? 19" North 87? 37' 33" West General Use To assist you further in identifying the location of the discharge please see the attached map. The stream segment. receiving the discharge from outfalls 001 and 002 is on the 2016 303(d) list of impaired waters and is not a biologically significant stream on the 2008 Illinois Department of Natural Resources Publication lnlegrating Multiple Taxa in a Biological Stream Rating System. The following parameters have been identified as the pollutants causing impairment: Designated Use Potential Cause Aquatic Life. Fish Consumption. and Primary Contact Changes in Stream Depth and Velocity Patterns. Loss of Instream Recreation Cover. Other Flow Regime Alternations. Dissolved Oxygen, Phosphorus (Total). pH. Mercury. PCBs. and Fecal Colilorm The discharges from the facility shall be monitored and limited at all times as follows: LOAD LIMITS lbs/day CONCENTRATION DAF (DMF1 LIMITS 30 DAY DAILY 30 DAY DAILY PARAMETER AVERAGE MAXIMUM REGULATION AVERAGE MAXIMUM REGULATION Outfall 001: Flow (MGD) Temperature The following explain the conditions of the proposed permit: The Special Conditions clarify flow. temperature. monitoring location, 316th), and discharge monitoring report submission. 316(b): Cooling Water Intake Structure (CWISI Description and Operation Discussion provided by the facility: The facility has two 36" intake lines which draw non-contact cooling water from the Chicago River. The new intake is located approximately 180' east of the North Wabash Avenue bridge (the bridge). The existing intake is located approximately 300? east of the bridge. The new intake was constructed during the hotel construction project and the existing intake was from the original Chicago Sun Times building. Openings in the 502' long sheet pile bulkhead were make to accommodate the intake lines. The openings are located several feet below normal water surface elevation. The river is about 19 20' deep at this location. Each of the openings in the bulkhead was to be 4'6? square. leading to reinforced concrete chambers 4'6" wide and 6'6? high. The chambers were run perpendicular to the bulkhead. extending back and connecting into the new building cooling water system. Each of the 4 openings were framed with 12" steel beams. welded onto the inside of the existing steel sheet piling. The framing was encased in concrete. A removable steel intake grate was provided. inside the framing, to minimize fish and river debris from entering the chamber and cooling water system. No portion of the new intake/outflow framing. or its structural components. was designed to extend beyond the face of the existing steel sheet pile bulkhead. is. the new construction was to be flush with the face of the existing sheeting. The entire cooling water system is looped in that the river water is continually drawn and discharged so that the total river flow will not be affected. The cooling water system and cooling water intake structed are intended for year-round. 24 hours/day operation. Inside the facility. the river water collects in two 6' wide 19'7" deep river water intake wells. There is a travelling screen located within each respective intake well. The travelling screen consist of 304 stainless steel rotating wire screen cloth (#12 gauge) with 3/8" Public Notice/Fact Sheet -- Page 3 -- NPDES Permit No. IL0079812 square openings. There is a 2 1/2? u-shaped spray wash header per travelling screen with brass spray nozzles. The multi-state pumps distribute water through the spray wash header to the spray nozzles to knock off debris into debris collection baskets that sit on top of each respective intake well. On the upstream side of the travelling screens. there are two 7.500 vertical turbine pumps with VFDs that run continuously. These pumps modulate to maintain a river water discharge flow greater than the return flow from the chiller flow with an adjustable offset. The river water from the vertical turbine pumps is pumped through 2 dedicated duplex basket strainer with 304 stainless steel baskets with 0.125" perforations. The duplex basket strainers have removable lids to remove and clean the baskets. Once the river water passes through the basket strainers. it is pulled through any of the three 5.00 base mounted river water pumps. Each of these respective pumps also has an inline strainer at the inlet side of the pumps. These pumps pump the river water directly through the 4.800 total tons worth of cooling via 4 chillers where it pumps up the rejected heat from the chillers and dumps back into the river via a 24" piping header. Agency Discussion: The following Special Condition language was in the previous permit for 316(b). ?In order for the Agency to evaluate the potential impacts of cooling water intake structure operations pursuant to 40 CFR the permittee shall prepare and submit information to the Agency outlining current intake structure conditions at this facility. including a detailed description of the current intake structure operation and design, description of any operational or structural modifications from original design parameters. source waterbody flow information, or other information as necessary. The information shall also include a summary of historical 316(b) related intake impingement and or entrainment studies. it any, as well as current impingement mortality and I or entrainment characterization data; and shall be submitted to the Agency within six (6) months of the permit's effective date. Upon the receipt and review of this information. the permit may be modified to require the submittal of additional information based on a Best Professional Judgement review by the Agency. This permit may also be revised or modified in accordance with any laws. regulations. or judicial orders pursuant to Section 316(b) of the Clean Water Act." The facility did not submit this information to the Agency as required by the special condition. The information that is discussed above was provided by the facility and submitted after the renewal application was received by the Agency. 40 states that all existing facilities must submit for review the information required under paragraphs - (B). At this time the facility has not submitted any of this information. To comply with the impingement standard. facilities are required to comply with one of the seven alternatives as outlined in 40 CPR At this time. the facility has not selected its intended method of compliance with impingement mortality standard. For entrainment. the facility has not previously conducted studies on entrainment. The facility withdraws less than 125 MGD therefore they are not required to submit the information required by (13). 40 CFR 125.94(d) states that the Agency must make a ETA determination for existing facilities on a site specific basis. At this time. the facility has not provided its demonstration of compliance with BTA for entrainment. 40 provides that an altemative schedule may be established for the submittal of certain application requirements (as necessary). for permits which expire on or before July 14. 201 and this permit expired on August 31. 2016. Pursuant to that section. the Agency hereby establishes an alternative schedule forthe submittal of (B) and a detailed demonstration of compliance with BTA for entrainment. This information should be submitted within 36 months of the effective date of this permit in accordance with Special Condition 9.
