Metal Reduction and Neutralization (lntemal OUtlet 203) 

II. RATIONALE FOR OUTLET 002 

The pennittee has JIB own water intake and water treatment plant to supply potable drinking water for its 

employees. Outlet 002 Is approximately 0.25 miles upstream of the water intake. The permittee has a 

variance which eldldes them from the ~ mile human health mixing zone prohibition. Thle variance Is found 

In 47 CSR 2, Section 7 .2.a.2 of the WVLR. As a result. of tnrs variance, the permittee Is allowed to have a 

mixing zone for water use Category A. 

Outlet 002 Mixing 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 of the discharge Ia the 7Q1 0 (5880 cfs). Thll value was 

reduced by the percentage of flow 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 the. largest ZID (Zone of Initial Dilution) rn order to 

achlev& 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 of the receiving stream. The CMZ exceeds 1/3 the width 

of the river at a distance of 432 meters downstream of the discharge. outlet 002 however is approximately 

0.25 miles (402 meters) upstream of the 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 of 49 dilutions was granted which occurs at 224 meters downstream and 89 meters from the 
Pennlt No. WV0003336 

Page 10of25 

10. RATIONAlE FOR PROPOSED EFFLUENT UMITATIONS 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 of the 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 of any 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 discharge 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 of the 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 4.5 

dilutions at a downstream distance of 1.5 meters, a CMZ of 49 diutions at a downstream distance of 224 

meters, and a CMZ-HH (CMZ-Human Health) of 49 dKutlons at a downstream distance of 224 meters. 

Outlet 002 WQBELs 

There was reasonable potential to exceed water quality criteria at the end of pipe but not at the edge of the 

granted site specific mixing zone for aluminum, ammonia, copper, lead, sulfate, and whole effluent toxicity 

(cerlodaphnia dubia) and WQBELs are not wananted. Continued monitoring is imposed. Calculations are 

attached to the fact sheet. 

There was reasonable potential to exceed water quality criteria at the end of pipe for benzene and Iron. A 

mixing zone could not be granted _since the background concentration in the Ohio River has not been 

established for benzene and Iron is 303(d) listed for this segment of the Ohio River. WQBELs are Imposed. 

calculations are $Uached to the fact sheet. 

There was reasonable potential to exceed water quality criteria at the end of ~ and at the edge of the 

granted site specific mixing zone for hexavalent chromium, free cyanide, total residual chlolfne, whole 

effluent toxicity (pimephales promelas), and total phenolics and WQBELs are imposed. Calculations are 

attached to the fact sheet.

10. RATIONALE FOR PROPOSED EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS (continued) 

A reasonable potential assessment was conducted to protect the 5 degree temperature difference WQC. A 

site specific mbcing zone of 4.5 dilutions for the ZID and 49 dilutions for the CMZ was granted. M the WQC Is

Whole Eftluant Toxicity (Outlet 002) 

The permittee monitored Outlet 002 for Chronic Whole Effluent Toxicity (Ceriodaphnla Oubla and 

Pimophales Promelas} during 1he term of the last permit. The test endpoint for chronic toxicity testing Is the 

No Observed Etrect Concentration (NOEC). Monitoring Indicated values of<~~: 1 TUc (NOEC at 100% ellluent) 

on 9 separate occasions for Cerlodaphnla Dubia. Monitoring also indicated values of 8 TUc on on occasion 

and <=1 TUc (NOEC at 100% eflluent) on 8 separate occasions for Pimephales Pmmelas. Using the 

procedures in EPA's Technical Support Document for Water Quality Based Toxlcs Control (TSD), a 

reasonable potential (RP} assesement was performed on the Chronic Whole Effluent Toxicity (WET) resulls.. 

The agency uses 0.3 TUa as an acute water quality criterion and 1.0 TUc as a chronic water quality crtterton 

to be protective of WV's narrative water quality slandards. A site specific mixing zone was granted zid=4.5, 

cmz=49. There was RP to exceed water quality criteria at the end of pipe and at the edge of a site specific 

mixing zone for Pimephales Promelc;~s, but not for Certodaphnia Oubla. Using the procedures in EPA's

In conformance with 40 CFR 122.44(a)(2), a monitoring waiver may be granted for pollutants not present In 

the discharge and not used at the site. Historical data has shown consistent non-detects for the pollutants 

Hsted in Section C.27 of the pennlt. As such, monitoring for these pollutants has been removed In 

accordance with 40 CFR 122.44 (a)(2). However, this regulation does not waive the pennit limitations for all 

applicable guideline-listed pollutants in 40 CFR 414 Subpart I. Therefore, a monitoring waiver is granted for 

the pollutants listed in C.27; however, the limitations shall remain In effect as listed in C.27. The pennittee 

requested a monitoring waiver for lead; however, the request could not be granted since lead exhibits a 

reasonable potential to exceed water quality criteria at Outlet 003. 

The permittee requested alternative eflruent limitations for naphthalene per 40 CFR 420.01 (b) of the ELGs; 

however, appropriate information required by 40 CF R 4201.01 (b )(iv) was not included wi1h the request. 

Therefore, the pennit writer cannot evaluate whether the permittee's belief that the cost of bringing the 

specified central treatment facility Into compliance requires expenditures so high that the applicable fimits in 

40 CFR 420 for naphthalene would not represent BAT. 

OUtlet 003 Mixing Zone 

The permittee perfonned 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 observed during the study. 

However, the agency models mb<lng zones at critical conditions and the maximum discharge flow rate. The 

crltlcal condition for the Ohio River in the area of the discharge Is the 7010 (5880 cfs}. This value was 
Permit No. WV0003336 

Page 13of25 

10. RAnONALE FOR PROPOSED EFFLUENT LIMITATIONS ANO MO.MTORING REQUIREIENTS (continued) 

reduced by the percentage of flow in the channel from Browns Island to the WV bank to 3,049 cfs. The 

highest discharge flow from Outlet 003 In the last five years was 14.1 MGO. These valu• ware used along 

with the calibrated model for ~ling purpoaas. In addiUon, a review of eflluent discharge data lndlcatss 

that free cyan ide fs the pollutant that needs the largest Zl D in order to achieve acute water quality criteria and 

free cyanide is also the pollutant that needs the largest CMZ in order to achieve chronic aquatic Ufelhuman 

health water quality criteria. 

The maximum CMZ length Is limited to 113 the width of the receMng stream. The CMZ exceeds 113 the width 

of the river at a distance of 90 meters downstream of the discharge. At this downstream distance, there are 

3.8 dilutions available. AS such, this is the maximum CMZ that can be granted. Based on historical effluent 

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 of the allowable mixing zone. As such, a CMZ of 3.8 dilutions was granted 

which occurs at 90 meters downstream. CORMIX prediction files are attached to the fact sheet. 

The discharge velocity is less than 10 feet per aecond and thU&, the maximum ZID Is limited to amallelt of 

the following: 50 times the discharge length scale {54 meters}, 5 times the depth at the dlschatge at low 

flow conditions (11 meters), or 10% of the CMZ (16.5 meters). The maximum ZID that can be granted cannot 

exceed 11 meters in any direction from the outfall. The mixing zone reaches 11 meters from the discharge at 

a downstream location of 3.2 meters from the outfall, 9.6 meters from the centerline, and 4.3 meters in the 

vertical direction. The dilutions evallable at this location Is 1.7. As such, this ia the maximum ZID that can be 

granted. Based on historical emuent data, the agency has detennined that free cyanide requires the most 

mbdng for acute aquatic life water quality criteria. Effluent data Indicates that lhe pennittae needs 11.4 

dilutions to meet the criteria and thus requires the full extent of the allowable mixing zone.AZID of 1.7 

dilutions was granted which occurs at 3.2 meters downstream. CORM IX pradlctlon flies are attached to the 

fact sheet. 

While permlssfble under law, the granting of any mixing zone results In exoeedances of water quality crlleria 

In the receiving stream wfthln the actual mixing zone granted. This results In degradation to the receiving 

atreem and !ncreeeea the potential for adverse Impacts to aquadc Afe and human health wlii*l the mixing 

zone Itself. As the size of a mixing zone In the receMng stream increases, the potent!al for adverse Impacts 

within that mixing zone also Increase due to: the larger area/zone of the stream where water quality criteria 

am being exceeded, the Increased mass/volume/concentration of the pollu1ant within the area/zone, and the 

Increased expoaure duration that occurs as the area/zone in the receiving stream Increases. Therefore, the 

agency believes that limiting the size of mixing zonet le crtticalln minimizing the potential for adver8e 

impacts with in ihe mixing zone. As such, the agency limits the afze of the mixing zones granted based on 

what tile discharge 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 antldegradallon 

requiranenta preecribed in 80 CSR 5 of the 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 1. 7 

dilutions at a downstream distance of 3.2 meters, a CMZ of 3.8 dilutions at a downstream distance of 90 

meters, and a CMZ-HH of 3.8 dilutions at a downstream distance of 90 meters.

(plmpephales promelas} and WaBELs are not warranted. Continued monitoring is imposed. Calculations 

are attached to the fact sheet. 

There was reasonable potential to exceed water quality criteria at the end of pipe for iron and bis(2· 

ethylhexyl )phthalate. A mixing zone could not be granted since Iron is 303( d) listed for this segment of the 

Ohio River and the average concentraton for bis(2-ethylhexyl}phthalate was above the wac. waBELs are 

Imposed. Calculations are attached to the fact sheet. 

There was reasonable potential to exceed water quality criteria at the end of pipe and at the edge of the 

granted site specific mixing zone (zld=1.7, cmz=3.8) for aluminum, trivalent chromium, free cyanide, fluoride, 

lead, nitrite nitrogen, selenium, zinc, whole effluent toxicity (cerfodaphnia dubia), total phenolics, and total 

cyanide and WQBELs are imposed. Calculations are attached to the fact sheet. 

waBELs were calculated to protect the 5 degree temperature difference wac. A site specific mixing zone of 

1. 7 dilutions for the ZID and 3.8 dilutions for the CMZ was granted. As the wac is prescribed as a 

temperature difference, the background concentration is not used In determining a discharge wasteload 

allocation or effluent limitations. Due to the water quality criteria being prescribed as a difference and not a 

foced value, H was deemed impractical to develop monthly average and maximum daily limitations using the 

procedures In EPA's Technical Support Document, and the wasteload allocation is being imposed as a 

maximum daily limit only which will be protective of the acute water quality criterion. Calculations are 

attached. 

A reasonable potential assessment was conducted to determine if WQBELs were needed to protect the 

temperature WQC. Background data for the Ohio River was prescribed for the Individual months to account 

for seasonal variations. A site specific mixing zone of 1. 7 dilutions for the ZJD and 3.8 dilutions for the CMZ 

was granted. A reasonable potential assessment was conducted over each of aforementioned time frames 

using each time frame's corresponding background data and projected temperature discharge levels 

provided. There was reasonable potential to exceed wac at end of pipe and at the edge of the site specific 

mixing zone for all months. The permittee continuously monitors temperature at this outlet and 1herefore the 

agency believes that an average monthly is not necessarily practicable and that If a permittee is continuously 

monitoring for temperature (with readings recorded at least once per hour) that the imposition of an average 

monthly limitation is not necessary and that the maximum dally limitation imposed as an instantaneous 

maximum limitation will be protective of water quality criteria. An acute water quality criterion Is a one hour 

average criterion not to be exceeded more than once every three years. The agency believes that continuous 

measurement of temperature on at least an hourly basis along with the imposition of an Instantaneous 

maximum temperature llmltaUon will be protective of water quality criteria for temperature. Temperature 

limitations have been imposed for all months at OUtlet 003 to impose an instantaneous maximum coupled 

with continuous measurement of temperature. Calculations are attached. 

Whole Effluent Toxicity (Ou11et 003} 

The permittee monitored Outlet 003 for Chronic Whole Effluent Toxicity (Cerlodaphnia Dubia and 

Pimephales Promelas) during the tenn of the laet permit. The test endpoint for chronic toxicity testing is the 

No Observed Effect Concentration (NOEC). Monitoring indicated values of 2 TUc on two occasions and <"' 1 

TUc (NOEC at 100% effluent) on 16 separate occasions tor Ceriodaphnia Dubia. Monitoring also indicated 

velues of <=1 TUc (NOEC at 1 00% effluent) on 18 separate occasions for Pimephales Promelas. Using the 

procedures In EPA's Technical Support Document for Water Quality Based Toxics Control (T$0), a 

reasonable potential (RP) assessment was performed on the Chronic Whole Effluent Toxicity (WET} results. 
Permit No. WV0003336 

Page 15of25 

10. RATIONALE FOR PROPOSED EFFLUENT UMITATIONS AND MONITORING REQUIREMENTS (continued) 

The agency uses 0.3 TUa as an acute water quafily criterion and 1.0 TUc as a chronic water quality cri1arion 

to be protective of WV's narrative water quality standards. A. site specific mixing zone was granted zid•1. 7, 

crnz=3.8. There was RP to exceed water quality crtterla at the end of pipe and at the edge of a site specltlc 

mixing zone for Ceriodaphnia Dubis, but not for Plmephales Promelas. Using the procedures in EPA's 

Technical Support Document for Water Quality Based Toxics Control {TSD), WQBELs are imposed for 

Ceriodaphnla Dubie and continued monitoring is imposed for Pimephafes Promelas in Section A.003 of the 

penn ft. 

OUtlet 003 Permit Limitations 

The ftow8 and production rates above were uaed in combilallon with the applicable ELGs to calculate 

equivalent concentrations at OUtlet 003 based on a combined wastestream mass balance which were then 

compared to WQBELs at Outlet 003. The minimum concentration was imposed In Section A.003. In addition, 

mass based limitations are imposed for Iron and Steel ELG based parameters. Calculations are attached to 

the Fact Sheet. 

Based on a DMR review the permittee cannot consistently meet the temperature limitations; therefore, a 24 

month compliance schedule has been granted. 

For he cyanide, total cyanide, 1rlvalent chromium, bls(2-ethylhaxyl} phthalate (OEHP), ftuoricle, iron, 

aluminum, and total phenolics the new permit limit Is significantly lower (free cyanide, trivalent chromium, 

DEHP) than the previous limit or was monitor only (fluoride, Iron, aluminum, total phenolics). Based on a 

OMR review, the new limits are not consistently achievable; therefore, a 24 month complian<;e schedule has 

been granted. 

IV. RATIONALE FOR OU11.ET 004 

Outlet 004 WQBELs 

The permittee discharges wastewater into Harmon Creek via Outlet 004. The 7Q1 0 of Harmon Creek is 1.07 

cfs, which makes the lnstream waste concentration 82% for the discharge from Outlet 004. As a result, no 

mixing zone can be granted. 

There was reasonable potential to exceed water quality criteria at the end of pipe for total f88idual chlorine, 

hexavalent chromium, free cyanide, fluoride, Iron, lead, zlnc, and copper. A mixing zone cannot be granted 

since the fiNC Is greater than 80%. WQBELs are imposed. Calculations are attached to the fact sheet. 

The pennlttee has been meeting the 5 degree temperature rise requirement at this outlet einc:e reduction of 

flow started In 07.12011. H0v.oever, background temperature data has not been reported for this discharge, 

moni1oring is imposed to establish a database.

Technical Support Document for Water Quality Based Toxlcs Control (TSD), a reasonable potential (RP) 

aasessment was performed on the Chronic Whole Effluent Toxicity {WEn results. The agency uses 0.3 TUa 

as an acute water quality criterion and 1.0 TUc as a chronic water quality criterion to be protective of WVs 

narrative water quality standards. A mixing zone could not be granted due to the instream wasta 

concentration In Harmon Creek being greater than 80%. There was not RP to exceed water quality criteria at 

the end of pipe for Cetiodapl'vlla Dubla or Pimephales Promelas. Continued monitoring Is imposed for 

Cerlodaphnla Dubla and Pimephales Promelas in Section A.004 of the permit. 

Outlet 004 Permit Limits 

For lead, hexavalent chromium, total residual chlorine, and copper the new permit limit Is significantly lower 

(lead) than the previous limit or was monitor only (hex chrome, total residual chlorine, copper). The new 

limits are not consistently achlevably; therefore, a 24 month compliance schedule has been granted. 

VI. RATIONALE FOR OUnET 097 

Outlet 097 is the intake for water used by the permittee and this outfall serves as an upstream monitoring 

location In the permit in order to collect background data for mixing zone and permit limit evaluations at next 

pennit relssuance. 

VII. RATIONALE FOR INTERNAL OUTLETS (103, 203, 303)

ANTIDEGRADATION 

An antldegradatlon review has been conducted. The outlets Identified In this permit are existing outlets. 

There are no new or expanded discharges In the relssuance of this permit. As such, Tier 1 protection is 

provided for the uses specified in Title 47, Series 2, Section 6. During the term of the previous WV/NPDES 

permit, the permittee has shown compliance with the previously established permit effluent limitations. 

There Is no proposed Increase In (1) the volume of discharges from the existing outlet, (2) the quantity of 

pollutants to be discharged from the existing outlet, or (3) any increase to the existing watment capacity of 

the WWTP. The Ohio River is designated for all water use categories as defined In 47 CSR 2, Section 6. 

The pennlt writer believes that the terms and conditions proposed in this draft penn it will maintain and 

protect the designated water uses of the receiving stream as well as the level of water quality necessary to 

protect said water uses. 

14. OTHER REQUIREMENT(s) 

316(b) OF THE CLEAN WATER ACT 

The permittee's facility Includes a cooling water Intake structure governed by Section 316(b) of the Clean 

Water Act (CWA), which requires that the location, design, construction and capacity of the cooling water 

intake structures reflect the best technology available (BTA) for minimizing adverse environmental Impact. 

In 2004, EPA promulgated regulations implementing CWA316(b) requirements for so--called ftPhase uw 

existing facilities. The Phase II regulations set national standards for cooling water withdrawals by large, 
PemmtNo.VVV0003336

existing power producing faclltles, such as the pennlttee's plant. On January 25, 2007, the U.S . Circuit 

Court of Appeals for the Second Circuit remanded several provisions of the Phase II rule on various 

grounds. See Rfverkeeper, Inc ., v . EPA (Riverteeper II], 475 F.3cf 83 (2d Clr. 2007). On March 20, 2007, 

EPA Assistant Administrator Benjamin Grumbles advised EPA regional oflices that ~[w]ith so many 

provisions of the Phase II rule affected by the decision, the ruSe should be considered suspended.· (See 

03120/07 Memorandum "Implementation of the Decision In Riverkeeper, Inc. v. EPA, Remanding the 

CooUng Water Intake Structures Phase 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) of the 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 of the 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 of the 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 over the 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 high 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 of the screen Is smaBer than the organisms susceptible to 

entrainmenL Hydrodynamic exclusion results from maintenance of a low through-slot velocity, which, 

because of the saeen's cylindrical ~uratlon, Is quickly dissipated. A general rule of thumb 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, 

entrainment Impacts at many different types of facilities 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 of fish from Intakes. These screens rely on gentle impingement of 

organisms on the screen surface. Successful use of fine-mesh screens is contingent on the application 

of satisfactory handling and return systems to alow the safe return of impinged organisms 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 of fuU-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 of the 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 of typically wide openings, 

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 H can 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 
Permit No. WV0003336 

Page23of25 

14. OTHER REQUIREMENT(s) (continued) 

be placed some distance from the cooling water intake structure within the source waterbody and act as a 

filter for the water that ente111 ths cooling water system. Mlcroftltratlon barriara show elgnlflcant promise 

for minimizing entrainment. Entrainment reductions of up to 82 percent went observed for eggs and 

larvae, and these levels Yo~ere maintained for extended 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 of the source waterbody may also preclude the beneficial use of such a system. 

BEHAVIORAL BARRIERS 

-louver systemslouver systems consist of series of vertical panels plae&d at 90 degree angfes to the direction of water 

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 of the 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 ScreensAngled 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 of the 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 at the 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 

other fish protection devices, such as screens with fish returns. 

- Porous Dikes and leaky DamsPorous dikes, also known as leaky dams or dikes, 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) of the 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) of the CWA and reflect BTA based on a BPJ 

determination.

The permlltee pruvtded comments on the draft pwmlt indicating that the hot 8trip mm wu cloud down In 

December 2007. A8 a result, the flowe have diminished algnlficantty at this outfall which means that the 

outfall hal len of an Impact on the downstream hardneas. Recant hardneaa data collected from January 

- Aprll2008 Indicates that the hardne8a upstream and downstream Of the di8charge are now staying 

relatively the same. The upttream hardness hu appeared to change 8s well. The average of the 

upstream hardness values from January-Aprtl2008 W8l'8 used to I"'HVVIIuate lfmlls for Jeed end zinc. 

·There was rM~onable potential to exceed water quality criteria at the end-of-pipe and I"888Qn8bbe 

potential to exceed WQBELs. A8 a result, the wQBEL& hive been revised In the permit Reasonable 

potential anafyMs and WQBEL calcl!llllons are attached to the .Fact Sheet Addendwn. The permltee 

al10 18queated a compHance achedule for fecal coliform lmltl at thle outfal. Upon review of data, the 

permittee cannot conalatently achieve the final eftluent limltaUons for fecal coliform. Therefore, the 

permll1ae ra being given two years to Implement appropriate measunMS to nieet the final limits for fecal 

coliform. The pennfttH lhaH have monitor only requirements until that time for fecal collrorm. Section

to malntafn lhe outfalll in c::aee operations reatarted in the future. However, the pemlltlee has now 

8Ubmitted commenlllndicating that theM will not be restarted and has l"8qU88ted their deletion. As such, 

they have bBBn deleted from the permit. Section C.19 ahi!IIJ remain In· the pennit The pennlttee 

requested deletion of Internal Outlet 504. This outfd Is not IUbjact to any effluent guidelines and has 

merely served as an Internal monitoring point In the past wlthoLJ any limitations. Since there has been a 

subatanUal reduction In operations and the total discharge at Outlet 004, this Internal outfall Is being 

deleted.

Background 

Tbe permittee has eliminated numerous dlacflarges In the pall. Prior to the previoue permit lsaued on 

February 28, 2003, the permittee had eliminated storm water Outletl 005-015 by combining the flows with 

other remaining outfalls. The permittee also eliminated Internal Outlet 304 by rerouting this discharge 

through the treatment plant at Internal Outlel404 as required by a Consent Decree. During this past penntt 

cycle, Weirton Steel, Inc. was sold to ISG Weirton, Inc., and then sold to Mitlal Steel, Inc., and retently 

changed Ita name to ArcelorMittal Weirton, Inc. AI part of thele transitions, the property located on Brown's 

Island was sold off to Tecumseh Redevelopment, Inc. At fil8t, the pennlt waa transfened to both Tecumseh 

Redevelopment and ISG Weirton with Tecumseh responsible for the discharge on Brown's Island (Outlet 

001} and ISG Weirton responsible for everything else. Teaunseh Redevelopment obtained Storm Water 

lnMtr'ial WV/NPDES General Permit ReglatratJon No. WVGe11~ on October a, 2008 to cover the 

discharge from Outlet 001. AJj a result, Tecumseh Redevelopment and the Outlet 001 discharge have been 

removed lhis permit. Outlet 016 was previously permitted as a potential overflow from wastewater that WP 

senl from lntemational Mill Service to M'lltal Steel's treatment at Outlet 002. International Mill Service has 

ceased operations and Outlet 016 has been capped off to ensure that no future overflows could occur. As 

such, Outlet 018 hal been eliminated from the permit. 

The .permittee has currently ceased operations at its blast fum ace and other steelmaking areas of the plant. 

Since at least JUly of 2005, there has been zero production from Internal Outlets 102 and 404. In addition, at 

lntcm:21 Outlot 104, there hu been zero production from the tl3 Pickler, til Tandem, and tl8 Tandem since at 

least July of 2005. Since theae operations .. 88Hntially ahut down, no monitoring requhments are beln,g 

Imposed at Internal Outlet Outlets 102 and 404. Tnese lntemal Outlets are being left in the permit In case 

the permittee decides to recommence operations In the future. In the meantime, no discharge Is currently 

permitted from Internal Outlets 102 and 404. The permittee may modify the permit in the future If It dec:idea to 

resume operations. Technology-Baaed Effluent LimOtatlons at Internal Outlet 1 04 do not giV& any credit ftom 

the #3 Pickler, 17 Tandem, and 18 Tandem am there has been zero production reported from them IInce 

at least July of 2005. The permittee may modify Its permit In the future to obtain additional productlo11-baaed 

credit for pollutanta limited at Internal Outlet 104 if it resumes operations at the #3 Pickler, tf1 Tandem, and 

t8Tandem. 

L RATIONALE FOR O.UTLET 001

The Permittee discharges wastewater Into the Ohio River via Outlet 002. Eflluent flow haa diminished at

Permit No. WV0003338 

Page8of29 

10. RATIONALE FOR PROPOSED EFFLUENT LIMIT AllONS AND MONITORING REQUIREMENTS (continued) 

Outlet 002 as a result of the shut down of the blaat fumaoe. The average of the maximum flows reported up 

to September 2005 was approximately 95 MGD While the average of the maximum flows since then is 

appn»dmately 35 MGD. Water quality ba88d effluent nmtts were developed for pol1utant& of concern using 

Ute moet atringent water quality criteria tom Wnt Virginia water QuaNty standards and ORSANCO Pollution 

Control Standards. 

The Permittee has its own water Intake and water tteatment plant to supply potable drinking watar for Its 

employees. Outlet 002 is approximately 0.25 miles upstream of the water Intake. The PermiUee has a 

variance which excludes them from tho~ mile human healh mbdng zone prohibition for iron until September 

1, 2010. This variance lsfolrld In 47 CSR 2, Section 7.2.a.2 of the WVLR. As a result of this variance, the 

Permittee Is allowed to have a mixing zone for water use Category A for Iron. After the variance expires, the 

Pennlttee muat meet end-of~plpe water quality criterion for Iron for water use Category A as prescribed in 47 

CSR 2, Section 8 of the WVLR or In ORSANCO't Pollution Control Standards, whichever is more atmgent. 

OUtlet 002 has Interim and final limitations proposed for iron to account for limitations with and without the 

variance. 

Outlet 002ls a low velocity surface discharge. Llmno. Tech, Inc. conducted a mbclng zone study 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 of this model. In addition, this model is not listed In the TSD or EPA's Modeling 

website as a mixing zone model. The etudy basically 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 confinn any of the results within the study. 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 that was 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 deeper than 5.5 meters, as this dlsctlarge does not protrude from the 

bank. Therefom, the zld cannot exceed 27.5 metenl. Rgure 10 of the mbdng zone report contains 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 the results ftDm the study, the agency is granting a dilution factor of 2 for the zld 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 the study yields a dilution factor of 4.5 for the chronic mixing zona. A dilution factor of 

1 Ia all that It allowed for C.tegory A water quality a-iteria. Lognonnal reasonable potential assessment& 

were conduc:ted using Di&charge Monitoring Report data reported by the permittee to impose WQBELs

Ill. RATIONALE FOR OunET 003 

The Permltllee discharges wa&bMater into the Ohio River via Outlet 003. The tfn mOl plating operations have 

remained the same since the isal.ance of the last permit and the long-term average disc:t11.-ge flow from 

OUllet 003 is about 9.2 MGD. The tin mill plating operation Ia subject to the Metal Finishing Eflluent 

Guideline (40 CFR 433.13 and 433.14). Baaed off of flows reported In the permit application, approximately 

73.9% of the total tow from OUIIat 003 Ia aubjecl to the effluent guldefine while the remaining 28.1% of the 

tow Is non-contact cooling waler end Is not IUbject to the gt.ldellna. As a reeu1t the guideline limitations 

were multiplied by 73.9%. catculations for these technology-basad effluent limftatlons are attac:hed to the 

fact sheet. 

A eille-spaclflc mf)dng zone was requested for pH at thia diiCharge which U88d the CORM IX mixing zona 

model. The permittee wanted to raise the pH of the discharge from Outlet 003 in order to remove mora zinc 

prior to discharge and was requesting higher pH Omits as a result. However, upon further review, an 

ina'ease in pH In the discharge will have a negative Impact on 1he removal of hexavalent chromium and may 

Increase the amount of hexavalent chromium dillcharged. 1he permit writer asked the permittee If It had 

ccnsldered this and the permlllae Indicated that It beHaved It could do withOut the pH mixing zone. The 

mixing zone lnfonnatlon submitted was used to model the mixing of the dlsmarge In CORMIX for other 

poftutants In order to grant sitfHpecific d~ution factors. The discharge from Outlet 00318 a submerged 

single port, low-velOCity diffuser. Brown's Island Is located in the middle of the Ohio River which makes It 

dlftlcult to determine an appropriate 1 Q 10 and 7Q1 0 low flow value, but the velocity of the Ohio River at these 

flows Is What Is necessary for CORMIX and not the receiving stream flow. It was assumed that the velocity of 

the river on each side of Brown's Island would be the same, therefore the velocity was determined as if 

Brown'& Island Ylas not there. This velocity Is 0.06 mls which is consistent with other low flow river velocllles 

found In other mixing zones in the Ohio River. However, Brown's lsh:md doeG have mn Impact on the width 

reetricllon to the mbdng xone. The width of the river at the clecharge 1&240 metan, eo the mixing zone

meter width restriction at 82 meters downstream of Outlet 003. This Is the largest mixing zone that can be 

granted and is the chronic mixing zone (cmz) berng granted by the agency. At 82 meters downstream, 

CORMIX predkD that there .. 13.9 dilUtion. IVBflable. Bacauae the valocity of the discharge is less than 

10 fps, the zone of Initial dilution (Zid) must be the amalleat of the foRowlng: 60 times the dllcharge length 

scale (54 m), 5 times the local receMng water depth at low flow conditions (27 .5 m), or 10% of the chronic 

mixing zone in any direction (8.2 m downstream and 8 meten; across). ThBrefore, the zid cannot extend any 

ful1her1han 8.2 meta's down&t'aam or 8 meters wide. CORMIX modeling predlela that 4.9 dilutions ara

concentrations were used in conjunction with a zld of 4.9 cilutions and a cmz of 13.9 dilutions to determine if 

there was reasonable potantllll for each pollutant. In general, there was rauonable potential to exceed aM 

water quality crltaria at the end-m.pipe for all pollutants mentioned. However, there was not reasonable

IV. RATIONALE FOR OUTLET 004 

The Permittee diadlarges wastewater into Harmon Creek via Outlet 004. Effluent flow has diminished at 

Outlet 004 as a result of the shut down of numerous steelmaking operations at the plant. The average of the 

maximum flows reported up to September 2005 was approximately 57 MGD while the average of the 

maximum flows since then Is approximately 43 MGD. Outlet 004 used to have a aoclo-ec:onomlc variance 

from water uae Category A designation. This variance was found in 47 CSR 2, Section 7.2.d.16.2 of the 

WVLR. The variance •peclflcally prescribed miDCimum dally limitations for lead, zinc, temperature, and Iron 

(monthly average also for iron). However, this variance expired on July 1, 2007. The permittee has reappiJad 

for this variance, but the West VU'Qinia Legislature failed to ad on It during its 2007 term and It may be acted 

upon during the 2008 term. Final water qualty-based effluent limitations were imposed In the permit without 

the benefit of the variance. Administrative Order No. 6245 was Issued on July 13, 2007 to address 

compliance Issues with the discharge for lead, zinc, temperature, and iron. 

The 7010 of Harmon Creek Is 1.07 cr., which makes the lnstream waste ooncentratlon 98% for the 

disCharge from OuUet 004. A& a result. no mbdng zone Is allowed. The Permittee showed reasonable 

potential for free cyanide, fluoride, Iron, lead, zinc, and chronic toxicity and water quality-based effluent 

imHations were imposed for each. Effluent limits were also imposed for temperature, total suspended 

solids, oil and grease, and fecal coliform. The permittee exceeded its previous permit limits for chronic 

toxicity and will continue to exceed the newly proposed limits in the proposed pei'J'YliL Administrative Order 

No. 6436 will be Issued with the final permit to address compliance Issues with toxicity. Reasonable 

potential caJcufationa and water quality-based effluent limits are attached to the fact sheet. PolkJant specific 

rationales are discussed later on.

VII. RATIONALE FOR INTERNAL OUTLETS 

As noted earlier, Internal Outlets 102 and 404 have not discharged due to sllut down In various operations at 

the faCility. As such, these Internal outlets were left In the permit with no monitoring requirements. The 

permittee must modify the permit prior to discharging from these outlets if it restarts operations in the future.

Flow Bate - Since volumes of storm water from the plant can vary considerably, It is difficult to limit the 

maximum flow rate at this outlet. Therefore, the Agency il proposing to continue the current requirement 

of monltoring1he flow at this outlet. 

Total Nitrogen - The DMslon has started to analyze the Impacts of nutrfenll upon water quality and 

whether there Is a need to astabllsh nutrient water quality standards. Therefore, the OMIIlon Is lmpoefng 

efluent sampDng for Total Nitrogen and Total Phosphorus in order to assist in this analysis. The Total 

Nitrogen value to be reported on the permittee's Discharge Monitoring Reports {DMRs) shall be the sum of 

the following parameters; Total Kjeldahl Nitrogen, Nitrate and Nitrite.

2. Water Quality Based 

Temperature -The highest temperature reported at OUtlet 002 has been 89 degraea F. An effluent linit of 

110 degrees was modeled to see what the effect would be on the receiving stream at low flow conditions. 

A 1Q10 Jow11ow value of 5,000 cfs was selected and then d'Nided by 3 since the discharge will not 

completely mix with the receiving stream. A tigh effluent flow of 68 MGD was selected. The highest

during the previous term of the penn it The pennlttee believes that the technology-based effluent limit 

previously Imposed of 10 mgn max dally was overly reabictive and led to the violations. The pennlttee also 

pointed out that most olher facilities have higher effluent limits for oil and grease. While the agency does 

note that the oil and grease limits previously lmpoeed appear to be tighter than uaual, it also recognizes 

that discharges cannot violate narrative water quaDty standards. As such, the agency Is granting higher 

limits for oil and grease on the concitlon that oiy sheens do not lead to violations of conditions not 

allowable under the State's narrative water quality standards as defined in 47 CSR 2, Section 3. This 

condition is imposed In Section C. A review of DMR data indicatea the permittee should be able to achieve

TSS -The proposed Umlts for TSS are based on treatment technology and can1ed over from the previous 

permit. The TSS limits are impoud on a net basis to allow for the levels of solids In the Intake water. Due 

to 1he shutdown of the blast furnaces, flows have significantly decreased at this outfall During the 

previous permit, It was documented that 66% of the discharge at Outlet 002 was non-contact c:ooHng water 

and that a net Hmit of zero was applicable to the non-contact cooling water as no solids would be added to 

this water. The remaining 24% of the discharge was water that could have added levels of solids. It is 

being asssumed that with the decreases In the total flow at Outlet 002, that the relative percentages are 

still the same. Therefore the technology-based Omit& of 30 mg/1 average monthly and 60 mgll max daily 

were multiplied by 34% and Imposed.

011 and Grease- The pennittee has had some comp&ance l8$ues with the oil and grease efftuent limit 

during the previous term of the pennit. The pennlttee beii8V88 that the technology-based effluent limit 

previously Imposed of 10 mgll max daily was overfy restrlcllve and led to the violations. The permittee also 

pointed out that most other facilltiea have higher effluent limits for oil and grease. WhRe the agency does 

note that the oil and grease limits previously Imposed appear to be tighter than usual, It alao recognizes 

that dfseharges cannot violate narrative water quality standards. As such, the 9ncy Is granting higher 

limits for oil and grease on the condition that oily sheens do not lead to violations of conditions not 

allowable under the state's narrative water quality standards as defined in 47 CSR 2. Sedlon 3. This 

condition is imposed In Section C. The limitations lmpoead are In accoolance with the Metal Flnslhlng

3. Water OUa!ltv Baled 

Temperature- The hJghest ternpe~ature reported at Outlet 003 has been 105 degrees F. An eflluent limit 

of 11 0 degrees was modeled to see what the effect would be on the receiving stream at low flow 

conaltions. OuUet 002 Is upstream of Outlet 003 and the effects of Outlet 002 were considered In this 

evaluation. An upstream low flow value of 1,769 cfs was selected based on the combined receiving 

stream flow and Outlet 002 discharge flow. A high effluent flow of 16 MGD was selected. An ambient 

receiving stream temperature of 84 degrees F was selected based off of the temperature mass balance at 

Outlet 002. It was assumed that the differences in specific heats between the discharge and receiving 

stream were negHgible. The following mass balance can be used to solve for downstream temperature. 

Td • (QeTe + QuTu)/Qd 

Te c: Effluent temperatura • 11 0 degrees F 

Qe "' Effluent flow • 25 cfs 

Tu • Upstream temperature = 84 degrees F 

Qu • Upswam low ftow = 1,769 cfs 

Qd = Downstream combined flow rate =- Qd +Qu = 1, 794 cr. 

Td = Downstream temperature .. ?? 

Td • 84.4 degrees F 

At this wonst case scenario condltlon, the receiving stream's water quality aiterta are achieved and the 

discharge raises the receiving stream temperature 0.4 degrees F which Is compliant with the 5 degree 

Increase water quality criterion. Therefore, a limit of 110 degrees F was imposed to ensure that water 

quality standards are maintained.

11. RATIONALE FOR VARIANCE DECISIONS 

The Permittee currently has the following variances: 

A. The Permittee discharges wastewater into the Ohio River via Outlet 002. The Permfttee has its own 

water intake IW1d water treatment plant to supply potable drinking water for ita employees. Outlet 002 Is 

within a% mile upstream of the water Intake. The Permittee has a variance which excludes them from 

the% mie rule until September 1, 2010. This variance Is found In 47 CSR 2, Section 7 .2.a.2 of the WVLR. 
Permit No. WV0003336 

Page 1:T of 29 

11. RATIONALE FOR VARIANCE DECISIONS (continued) 

Aa a result of this variance, the Permittee it allowed to have a mbdng zone for water uae Catllgary A fer 

Iron. After the variance expires, the Permittee must meet end.:oJ-pipe water quality crfterlon for Iron for 

water use Category A as prescribed in 47 CSR 2, Section 8 of the WVL.R orin ORSANCO's Pollution 

Control standards, whichever is more stringent. Outlet 002 tas interim and finallmitatfons proposed to 

account for limitations with and without the variance. 

B. The Pennittee discharges wastewater Into Hannon Creek or the Ohio RNer via Outlet 004. The 

Permittee's discharge from Outlet 004 falls into the segment of Hannon Creek which used to have a 

socio-economic valance from water use Category A designation. This variance was folnlln 47 CSR 2, 

Section 7.2.d.1 5.2 of the WVL.R. The variance apaclftcally pnlaCI'Ibed maximum daily limitations for lead, 

zinc, temperatura, and iron (monthly average also). Howevw, this variance expired on July 1, 20f11. The 

permittee has reapplied for this Yariance, but the West Vif!jnla LegisJatura failed to act on It during ita 

2007 term and It may be acted upon during the 2008 term. RnaJ effluent Imitations were impoaed In the 

permit without the benefit of the variance. Administrative Order No. 8245 was Issued on July 13, 2007 to 

addnlsa compliance lsauea with the discharge. 

C. Internal Outlet 1 02 uaed to have a 301 (g) variance for total ammonia and total phenols. The process 

at fntemal Outfat 102 has been idle slnc:e July 2005 and has not discharged since. As a result. this 

vari~W:ela not being granted at this Ume. Internal OUtlet 102 doea not contain any monitoring 

requirements. The permittee may modify the pennlt In the future If operations recommence at this 

discharge and rnay also request a 301 (g) variance at that time if it Is necessary.
