### ZOne · The permittee performed a dye study In the Ohio at this outlet 

### in 2009. Based on 

### the results CORMIX 

### was calibrated 

### to approximate 

### the dilutions observed at non-critical conditions obsetved during the 

### study. 

### However, the agency models miXIng zones at critical e9nditions and 

### the maxinalm discharge flow 

### rate. The crtllcaJ 

### condition for the 

### Ohio 

### River In the 

### area 

### ofthe discharge Ia the 

### 7Q1 0 (5880 

### cfs). Thll value was reduced 

### by the percentage offlow In the channel from Browns Island to the WV bank to 2,949 

### cfs. The highest discharge 

### flow from Outlet 002 in the last five years 

### was 30.5 MGD. These values 

### were used along 

### with the calibrated model for modeling purposes. In addition, a review of effluent discharge data indicates that total residual chlorine Is the poUutant that needs

### acute water quality crlterta and total 

### phenolics Is 

### the pollutant that 

### needs the largeSt CMZ (Chronic Mixing Zone) in older 

### to achieve chronic aquatic life/human health water quality crtterla. The 

### maximum CMZ length Is limited to 1/3 the 

### width ofthe receiving stream. The CMZ exceeds 1/3 the 

### width 

### ofthe river at a distance 

### of432 meters downstream 

### ofthe discharge. outlet 

### 002 however is 

### approximately 0.25 miles (402 

### meters) upstream 

### ofthe site's water intake. 

### N. this downstream distance, lhent are 60.7 dilutions available. As such, this is the maximum CMZ that can be granted. Based on historical effluent 

### data, the agency has detennined that 

### total phenolics requires the most mixing 

### for chronic aquatic lire/human 

### health water quality cr1terta. Effluent data indicates that 

### the pannlttee needs 49 dilutions 

### to 

### meet the crfteria. 

### As such, a ZID 

### of49 dilutions was granted which occurs at 224 meters downstream and 89 meters from the

### ANO MONITORING REQUIREMENTS (continued) centerline. CORM 

### IX prediction 

### files are attached 

### to the 

### fact 

### sheet. The discharge velocity is less than 

### 10 feet per second and thus, 

### the maximum ZID is limited 

### to smallest of the following: 50 

### times the discharge length scale (28.3 meters), 5 times the depth at the discharge at low flow 

### conditions (17.8 meters), or 10% of the CMZ (40.2 meters). The maximum ZID that can be granted cannot exceed 17.8 meters in any direction from the outfall. The mixing zone reaches 17.8 meters from the discharge 

### at a downstream location of 1.5 

### meters from the outfall 

### and 17.6 

### meters from the centerline . The dilutions available 

### at this location is 4.5. As such, this Is the maximum ZID that can be granted. Based on historical effluent 

### data, the agency has detennlned that 

### total residual chlorine requires the most mixing 

### for acute 

### aquatic life water quality criteria. Effluent data Indicates that the pennittee needs 

### 12.1 dilutions 

### to meet the criteria and thus requires the full extent ofthe 

### allowable mixing zone. A ZID of 4.5 dilutions was granted which occurs at 

### 1 .5 meters downstream and 

### 17.6 metels from the 

### centerline. 

### CORM IX prediction files 

### are 

### attached to the fact 

### sheet Whle pennlsslble under 

### law, the granting ofany mixing zone results in exceedances of

### water quality criteria in the 

### receiving stream 

### within the actual mixing zone granted . This results 

### in degradation to the receiving stream and increases the potential 

### for adverse Impacts to aquatic life 

### and

**h~.man** 

### health within the mixing zone itself. As 

### the size of 

### a mixing zone in the 

### receiving stream increases, the potential for adverse Impacts within that mixing zone also increase due 

### to: the larger area/zone of

### the stream where water quaJity criteria are 

### being exceeded, the increased mass/volume/concentration of the pollutant within the 

### area/zone, and the Increased exposure duration that occurs as the area/zone in the receiving stream Increases. Therefore, the agency believes that limiting the size of mixing zones Is critical in minimizing the potential for adverse Impacts within the mixing zone. As 

### such, the agency limits the size of the mixing zones granted based on what 

### the di scharge actually needs In order 

### to be compliant. In limiting the size of the mixing zone being granted to what Is needed, the agency is limiting the potential for 

### adverse Impacts 

### to aquatic life 

### and 

### human health Within the receiving stream. The agency further believes that this is consistent 

### with antidegradatlon requirements prescribed in 60 CSR 5 ofthe WV Legislative Rules which 

### were prescribed to limit degradation to receiving streams 

### in the 

### state. The mixing zone granted herein 

### consists of a ZID of

### Based on

### data, the agency has determined that free cyanide requires 1;he most mixing for chronic aquatic lifelhuman 

### health water quaUty criteria. Eftluent data Indicates that the permittee needs 89 dilutions 

### to meet the crttarfa and 

### thus requires the fun extent ofthe allowable mixing zone. As

### As the

### II Regulation," available 

### at http://www.epa.gov/w8t8r8Cience/316b /phaae2/fmplementation-200703.pclf) On 

### 719/2007 EPA issued a Federal Register 

### notice that 

### formaly suspended the 

### rule. In the interim, all NPDES pennits for Phase II facMities must indude conditions under 316(b) ofthe 

### CWA developed on a 

### best profeesional Judgment 

### (BPJ) besls, eee 40 C.F.R. 401.14. 

### Accordingly, this 

### permit Includes conditions designed 

### 1o ensure 

### that the WVDEP has the information necessary to make a BPJ deterrnk\atron of 

### CWA316(b) compiance conditions. 

### Section 0 

### ofthe pennlt 

### contains 

### these requirement&. 

### Speci11cally, 

### the permit identifies potential opUons for BTA and requires 

### the permittee 

## to submH a compliance demonstration work plan (COWP) In 

### order to 

### ensure compliance 

### with 316(b) of

### the Clean Water Act. The US EPA compiled a database 

### on the performance 

### ofthe 

### range of

### technologies currently 

### used by 

### facilities 

### to minimize impingement and entrainment {I&E) at power plants nationwide. This information was complied Into a development document. ·For Impingement control technologies, performance 

### is compared 

### to conventional (unmodified) travelng screens, the baseline technology. These screens are the most commonly used intake technology 

### at older existing faclities 

### and their operational performance Is well 

### established. 

### In general, these technologle& are deelgned 

### to

**pre~** 

### debde from 

### entering the 

### cooling 

### water system, not 

### to minimize I&E. The most common Intake designs include

**front~end** 

### trash reeks (usually consisting of

### fixed bars) 

### to prevent 

### large debris 

### from entering 

### the 

### system. The following technologies 

### were evaluated 

### by the 

### EPA and listed 

### as potential technologies to achieve the 

### I&E performance standards 

### In order 1o 

## meet the 

### requirements of 

### 316(b) ofihe 

### Clean WatBr

### Ac:t. In general, these technologies fall fnto 

### approximately four categories; flow 

### reduction systems, coJiection and retum systems, diversion and return systems, and behavioral barriers. FLOW REDUCTION SYSTEMS 

### -Intake VelocityThe I&E performance standards have been deemed to 

### achieved In the development document If

### a facility can demonstrate that 

### the 

### flow has been reduced 

### to levels commensurate 

### with dosed-cycle reclrculati1g systems. The development document has also recognized 

### that facilities that 

### can reduce thefr average design Intake 

### flow wloclty 

### to lesa lhan 0.5 fps are deemed to have met the Impingement perfotmance 

### standards, but muat still 

### demonstrate entrainment reduction. COLLECTION AND RETURN 

### SYSTEMS -Modified 

### Traveling Screens and Fish Handling and Retum System.- Conventfonal 

### traveling screens can be 

### modified so that 

### tlsh Impinged on the 8CAiena can be 

### ntmoved with minimal 

### stress and 

### mortality. Fish buckets and/or baskels 

### hold 

### the fish 

### in water until the 

### screen rises to a point at 

### which the fish are 

### spilled onto a bypass, trough, 

### or other protected area. Removed fish are typically tetumed 

### to the source waterbody by sluiceway or pipeline. Studies conducted at steam 

### electric power generating facilltlae overthe 

### past lhree decades have built a sizable record demonstrallng the performance potential for modified traveling screens that Include some form of

### fish retum• .Pennit No. WV0003336 Page22 of25 14. OTHER REQUIREMENT(s) (continued) Comprehensive studies have shown that modified screens can achieve an increase In 

### the 

### postimpingement survival of aquatic organisms that come under the influence of cooling water intake structures. Hardier species, as might be expected, have exhibited survival rates as hi gh as 100 percent. More fragile species, which are typically smaller and more numerous in the source waterbody, understandably have lower survival rates. Data Indicates, however. that with fine tuning, modified acreen systems can Increase survival rates for even the most susceptible species. DIVERSION AND RETURN SYSTEMS --Cylindrical Wedgewire ScreensWedgewlre screens are designed 

### to reduce I&E by physical exclusion and by exploitation of hydrodynamics and the natural flushing action of currents present 

### in the source waterbody. Physical

**exci~Bon** occurs when 

### the mesh size ofthe screen Is smaBer than the organisms susceptible to entrainmenL Hydrodynamic exclusion results from maintenance ofa 

### low through-slot 

### velocity, which, because of

### the saeen's cylindrical

**~uratlon,** Is quickly dissipated. A general rule ofthumb 

### holds that a 

### lower througiHiot velocity, when combined 

### with other optimal factors, 

### will achieve significant reductions In enttainment and impingement A sufficient ambient current must be present In the source waterbody to aid organisms In bypassing the structure and to remove other debris from the screen face. Cylindrical wedgewire screens have been effectively used to mitigate impingement and , under certain conditions , entrai nment Impacts at many different types offacilities over the past three decades. Although not 

### yet widely used 

### at steam electric power plants, limited data Indicates 

### that wide mesh screens, 

### tn particular, 

### can be 

### used 

### to minimize Impingement. -Fine Mesh ScreensFine-me5h screens are typically mounted on conventional traveling screens and are used to exclude eggs, larvae, and juvenile 

### torms offish from Intakes. These screens rely on gentle impingement of organisms on the screen surface. Successful use offine-mesh screens is contingent on the application of satisfactory handling and return systems 

### to alow

### the safe return ofimpinged organi sms 

### to the 

### aquatic environment Similar

### to fine-mesh wedgewlre 

### screens,

**fi~h** traveUng 

### screens with 

### ftsh ret.um systems 

### show promise for control of both impingement and entrainment. Despite the laclc offuU-scale 

### data, limited studies have shown that fine-mesh screens can reduce entrainment by 80 

### percent or more. 

### This reduction is contingent on optimized operation and intensive maintenance 

### to avoid biofouling and clogging, especially in marine environments. It might also 

### be appropriate to use removable fine mesh that Is ins181led only during periods of egg and larval abundance, thereby reducing the potential for clogging and wear and tear on the systems. -Fish Net BarriersFish net barriers are wide-mesh nets 

### that are placed In front ofthe entrance 

### to intake structures. Barrier nets have clearly proven effective for controlling Impingement (I.e., more than 80 percent reductions over conventional screens without nets) In areas 

### with limited debris flows. Because oftypically wide open ings, 

### they do not reduce entrainment of eggs and larvae . Experience has shown that hlgh debris ftows can cause significant damage 

### to net , systems. Blofoullng can also 

### be a concern but Hcan be addressed through frequent maintenance. In addition, barrier 

### nata are also often used only 

### seasonally where the source waterbody is subject to freezing . Fine-mesh banier nets show some promise for entrainment control but would likely require even more intensive maintenance. In some cases, the use 

### of barrier nets might be further limited by the physical constraints and other uses of the waterbody. -Aquatic Mlcrofiltration BarriersAquatic mJcroftltration 

### barrier systems are barriers that employ a filter fabric designed 

### to allow water to pass Into a cooling water Intake structure but exclude aquatic organisms. These systems are designed 

### to

**Yo~ere**

### month-to-month pertods 

### In one study. 

### However, some operational difficulties heve affected IOI'Ig-term performance. Sizing a· nd the 

### physical limitations and other uses ofthe source waterbody may also preclude the beneficial use ofsuch a system. BEHAVIORAL BARRIERS 

### -louver systemslouver systems consist of

### series ofvertical panels plae&d at 90 degree angfes 

### to the direction ofwater 

### flO\¥. The placement of

### the louver panels provides both changes In both the 

### flow direction and velocity, 

### which fish tend 

### to avold. The angles and flow velocities ofthe 

### louvers create a current parallel 

### to the face of

### the louvers that carries fish 

### away from the intake and Into a 

### fish bypass system for retum 

### to the source 

### watetbody. Louver systems can reduce Impingement losses bas

_ ed on fishes' 

### abiitles to recognize and swim away from the 

### barriers. Their performance, I.e., guidance efficiency, is 

### highly dependent on the length and swimming abilities of

### the residant sp8c1e1 . Because eggs and early stages of

### larvae cannot swim away, they 

### are nOt affected 

### by the dlverak)ns and there is 

### no associated reduction in entrainment Overall, data indicates that louvers can be 

### highly effective (more than 70 percent) in diverting fish from potential impingement. Latent 

### mortality Is 

### a concern, especially where fragile 

### species are 

### present. Similar to modified screens with fish 

### return systems, operators must optimize louver system 

### design to mJnlmize fish injury and mortality. -Angles and Modular Inclined Screens

### Angled traveling screens use standard through-flow traveling screens in v.ttich the screens are set at an angle 

### to the Incoming tlow. Angling the 

### 1creens improves 

### the ft8h 

### protection effectiveness

**b~U88** 

### the fish 

### tend 

### to avoid the screen 

### face and move 

### toward the end 

### ofthe screen line, assisted 

### by a component of 

### the Inflow velocity. A fish bypass facility with Independently induced flow must be provided. Angled traveling screens 

### with fish 

### bypass and return systems wort< simHar1y 

### to louver systems. They 

### also provide only potential reductions in impingement mortality because eggs and larvae will not generally detect 

### the factors that lniluence diversion. Similar 

### to louvers, angled screens show potential 

### to minimize Impingement by 

### greater than 80 to 

### 90 percent. Mom wldasprsad 

### full-scale use is necessary 

### to determine optimal design specifications and verffy that they 

### can be used on a widespread basis. -Velocity 

### CapsA velocity cap Is a device that is placed over a vertical Inlet 

### at an offshore Intake. This cover converts veltlcal flow 

### into horizontal flow atthe entrance to tile intake. The device 

### works on the premise that flsh will avoid rapid changes In horizontal flow 

### but are less able to detect and avoid vertical 

### velocity vectors. Velocity caps have 

### been installed 

### at many offshore intakes and have usually been successfuJ in minimizing 

### inplngement They do not provide reductions In entrainment of

### eggs and larvae, 

### which cannot dlsdngulah flow 

### characterfstlcs. As 

### noted In ASCE (1981), veloclly 

### caps are often used in conjunction with otherfish 

### protection devices, such as screens 

### with fish 

### returns.

- Porous Dikes and 

### leaky DamsPorous dikes, also known 

### as leaky dams ordikes, are filters that 

### resemble a breakwater surrounding a coonng water intake. The dike 

### acts as both a physical and a behavioral barrter 

### to aquatic organisms. Tests conducted 

### to date have indicated that the 

### technology is effective in excluding juvenile and adult flsh. The major problems associated 

### with porous dikes come from clogging by debris and 

### silt, ice buildup, and colonization by fish 

### and plant life. Porous dike technologies work on the pramlae that aquatic organisms wiA not pass through 

### physical barriers In front 

## or an Intake. They also operate with low approach velocity,

### Permit No. WV0003336 Page 24of25 14. OTHER REQUIREMENT(&) (continued) 

### further increasing the potential 

### for avoidance. They 

### will not, however, prevent entrainment by nonmotile larvae and eggs. Much 

### of the research on porous dikes and 

### leaky dams was 

### performed in the 1970s. In some examples, entrainment avoidance for juvenile and adult finfish was observed to be 

### nearly 100 percent. As indicated 

### in the 

### above examples, porous dikes and leaky dams show potential for use in limiting the passage of 

### adult and juvenile fish and, 

### to some degree, motile larvae. CONCLUSION Tile technologies presented can 

### substantially reduce impingement mortality and entrainment. With proper design, Installation, and operation and maintenance, 

### a facility 

### can realize marked reductions. However, 

### the development document has recognized that there Is a 

### high degree of

### variability in the 

### performance of each technology, which Is In part due 

### to the site-specific environmental conditions at a given 

### facility. The development document Indicates that these technologies can meet necessary perfonnance standards in order 

### to comply with 316(b) ofthe CWAand therefore reflect the BTAbased on a BPJ determination. While the development document acknowledges that 

### site-specific factors may affect the 

### efficacy of 

### l&E reduction technologies, it indicates that there are a reasonable 

### number of options 

### available from which most faciiHies may choose 

### to meet the performance standards. It 

### also indicates that, In cases 

### where one 

### technology cannot meet the perfonnance standards alone, a combination of 

### additional intake technologies, operational measures and/or restoration measures can be employed 

### to meet the perfonnance standards to comply 

### with 316(b) 

### ofthe CWA and reflect BTA based on a BPJ determination.Pennit

### In 1995 on behalf Weirton Steel uaing 

### the PDSM Model . The study 

### Indicates that 

### this model 

### was a US EPA developed mbdng zone model 

### from 1984. The 

### agency c:antacled 

### EPA in an 

### attempt to 

### obtain this 

### model However, EPA Region 

### 31s unaware ofthis model. In addition, this model is not listed In the TSD or EPA's Modeli ng website as a mixing zone model. The etudy 

### basi cally gives a summary of

### the results. The 

### agency typically uses CORMIX 

### to verify mixing zone dilutions and establsh boundaries in 

### accordance with 

### mbdng zone rules. N a result, the 

### agency was ll'l8ble 

### to

### As noted earlier, 

### this is 

### a low velocity 

### surface dhlcharge 

### whic:h typically is 

### the worst possible 

### case fer 

### a good 

### mbdng zone . As 

### a result, the zid must be limited to 5 times the receiving water depth 

### at the discharge during low 11ow conditions. Outlet 003 has a mixing zone thatwas modeled u&fng COR MIX (dl&cussed under Rationale 

### for Oudet 003). The local depth 

### at the discharge 

### at Outfall 003 is 5.5 meters, with the dlscnarge pipe protruding Into the Ohio River 1.28 meters 

### away from the bank. 

### l'herefi)re , the agency Is 

### assuming that 

### the local water depth during 

### low 

### 1Jow conditions at outlet

### 002 Is 

### no deeperthan 5.5 

### meters, as this 

### dlsctlarge does 

### not protrude 

### from the bank. Therefom , the zld cannot 

### exceed 27.5 metenl. Rgure 10of

### the mbdng zone report 

### contai ns a graph that plots forecasted dilution factors from the 

### PDSM model 

### with downatream diablnces during critical low flow 

### conditions of 

### the Ohio River. At 27.5 meters It 

### appeara that a dilution 

### factor of 1 is 

### avaUable. As it 

### is dlffiaJit 

### to lnterpntt

### for Outlet 002. This Is 

### consistent with other 

### zid& granted In 

### the Ohio River for Anllar 

### discharge 

### configlntions. The chronic mixing zone Is being truncated at the Intake 

### which Is approximately ..00 meters downstream of

### Outlet 002. Using Figure 1 0 of
