## Industrial Discharger Analyses

The U.S. Environmental Protection Agency (EPA) is proposing numeric nutrient criteria applicable to estuaries, coastal waters, and South Florida inland flowing waters in the State of Florida. The proposed criteria will supplement the state’s existing narrative nutrient criterion. Although the proposed rule does not establish any requirements directly applicable to regulated entities or other sources of nutrient pollution, EPA developed an economic analysis to provide information on potential costs and benefits that may be associated with state implementation requirements that may be necessary to assure attainment of water quality standards (WQS). The potential costs associated with state implementation may include costs to control discharges of nutrients from industrial facilities to waters covered under the proposed rule. EPA’s method for estimating potential costs in this sector is described in the economic analysis (see Economic Analysis of Proposed Water Quality Standards for the State of Florida’s Estuaries, Coastal Waters, and South Florida Inland Flowing Waters in the docket for the proposed rulemaking). This document provides supporting information for EPA’s analysis of incremental costs for the industrial sector.8



## Chemical and Allied Products Trademark Nitrogen Corporation NPDES permit number: FL0000647 Major/minor: Minor SIC code: 2873 (Nitrogenous Fertilizers) Industrial Category: Chemicals and Allied Products Design Flow: Not reported Average Flow: 0.11 mgd (average of monthly maximum flows from 2006 - 2010) Receiving Water: Unnamed ditch to Palm River to McKay Bay

Description Trademark Nitrogen Corporation is a fertilizer production plant, consisting of a 125 ton per day nitric acid plant, a 150 ton per day ammonium nitrate plant, a fertilizer solution plant, a magnesium nitrate plant, a nitrogen-phosphorus-potassium blend plant (liquid fertilizer), and a small boiler plant. Wastewater consists of boiler blowdown, boiler water softener backwash, cooling tower blowdown, once-through noncontact cooling water, and stormwater runoff. All wastewater except the cooling water is treated in an unlined, hyacinths vegetated detention ditch, which discharges through Outfall D-001 to Palm River, thence McKay Bay. The ditch system provides for uptake of nutrients and settling of solids. Noncontact cooling water is piped directly to a basin downstream of the vegetated ditch. Summary of Effluent Data and Limits

Exhibit 1 summarizes average monthly effluent data for TN from 2006 to 2010. TP data are not available from EPA’s ICIS-NPDES database, however, a laboratory report indicates that in 2008, TP concentrations were approximately 0.048 mg/L (FDEP, 2008d). There are no effluent limits for TP in the current permit. Exhibit 1: Effluent Data Summary, Trademark Nitrogen Corporation

Represents average of maximum monthly values. TP data from 2008 laboratory report. 2. Represents monthly average limit; permit also contains a daily maximum limit of 5.0 mg/L. In addition, the 5-year rolling average for TN may not exceed 200 lbs/yr.

Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 0.49 mg/L and 0.175 mg/L, respectively, for McKay Bay (Segment ID 0901) of the Tampa Bay Estuary. The Trademark Nitrogen Corporation is already covered under the McKay Bay TMDL, and has a WLA for TN of 3.0 mg/L, which it is currently meeting. Therefore, EPA assumes that the TMDL TN targets would be adopted as site-specific alternate criteria (SSAC), and that TN effluent limits would not be revised as a result of the proposed rule.9

Analysis of water quality data for TP indicates that the McKay Bay segment is exceeding EPA’s proposed annual geometric mean criterion of 0.175 mg/L. Given a lack of assimilative capacity the discharger is not likely to receive dilution. Exhibit 2 summarizes the RP analysis and estimated projected effluent limits for the facility.

The exhibit indicates that the facility would not likely have RP under the proposed rule because the average effluent concentration is below the proposed criterion. Thus, EPA assumes that an incremental level of control would not be necessary for compliance with revised effluent limits under the proposed rule and costs would be zero.10



## Electrical Services

Florida Power and Light, Indian River Plant NPDES permit number: FL0001538 Major/minor: Major SIC code: 4911 (Electrical Services) Industrial Category: Electrical Services Design Flow: 1, 348 mgd for Outfall D-001 Average Flow: 0.22 mgd for Outfall D-0B3; 0.12 mgd for Outfall I-012; 309 mgd for Outfall I-113; 326 mgd for Outfall I-114 (average of maximum monthly values from 2006 through 2011) Receiving Water: Intracoastal Waterways

Description Florida Power and Light, Indian River Plant is an electrical generating plant consisting of four natural gas and oil powered units with a total production capacity of 1,254 MW. The plant generates various forms of wastewater including once-through cooling water, sluice water, economizer hopper wash, air preheater wash, dust collector wash, equipment wash, boiler fireside wash, stack wash and water treatment effluent streams. The low volume wastewater treatment system consists of a solids settling basin, a precipitation basin, and a percolation basin. The solids settling and precipitation basin are lined with an impermeable liner, while the percolation basin has a limestone bottom (for enhanced precipitation of some dissolved metals). The water treatment system consists of multimedia filters, carbon filters, softener, RO, and mixed bed demineralizers. Florida Power and Light, Lauderdale Plant discharges once-through condenser cooling water, which maybe intermittently chlorinated for biofouling control, through Internal Outfalls I-111, I-112, I-113, and I114 and once-through auxiliary cooling water through Internal Outfalls I-181, I-182, I-183, and I-184 discharge. However, during periods of reserve shut down or periods of circulating water pump malfunction, the facility may divert a portion of the auxiliary cooling water through the main condensers and discharges it through Internal Outfalls I-1D1, I-1D2, I-1D3, and I-ID4. Outfall D-001 serves as the common point of discharge for the condenser cooling water and auxiliary cooling water. Outfall D-001 discharges effluent to a discharge canal that ultimately discharges into the Intracoastal Waterway. This discharge canal also receives effluent from other NPDES permitted dischargers in the Port Everglades

area. Boiler blowdown is normally routed to the boiler blowdown recovery basin for reuse. Boiler blowdown may also be routed to the solids settling basin or discharged directly to the intake canal through Internal Outfall I-016. Water treatment system effluent streams (including dust collector sluice water, economizer hopper wash, air preheater wash, equipment wash, dust collector wash, boiler fireside wash, stack wash, boiler chemical cleaning rinse water, carbon filter backwash, softener regeneration, and RO reject) are discharged either to the solids settling basins and their respective overflow areas or directly to the intake canal through Internal Outfall I-012. The equipment area runoff treatment system collects the first inch of rainfall plus minimal flows from theservice water rinses in the power block area. Drainage from oil contaminated areas passes through oilwater separators or oil traps. Runoff in excess of the first inch is routed directly to the discharge canal via11

Internal Outfall I-1B1. Stormwater from the diked tank farm areas discharges to the intake canal via Internal Outfall D-1B2 (North Tank Farm) or the plant discharge canal via Outfall D-0B3 (East Tank Farm). Intake screen wash water discharges through Outfall D-019. Summary of Effluent Data and Limits TN and TP data are not available from EPA’s ICIS-NPDES database. However, a laboratory report indicates that in 2008, TN concentrations were approximately 0.41 mg/L and there was no detection for phosphorous (FDEP, 2008c) for Outfall D-001. There are no effluent limits for TN and TP in the current permit. Exhibit 3 summarizes these data. Exhibit 3: Effluent Data Summary, Florida Power and Light, Indian River Plant

Potential Incremental Impacts Florida Power and Light, Indian River Plant discharges to coastal waters, for which EPA is proposing only chlorophyll-a criterion. While there are no TN and TP criteria, EPA assumes that Florida Power and Light, Lauderdale Plant would be required to meet the concentrations associated with economically feasible treatment (i.e., 3 mg/L for TN and 0.1 mg/L for TP) to reduce the potential for exceeding the chlorophyll-a criterion. Given the lack of permit requirements, the nature of the wastewater (e.g., mainly once-through cooling water), and the low TN concentrations in 2008, incremental controls and costs under the proposed rule are unlikely.12 

### Florida Power and Light, Fort Lauderdale Plant NPDES permit number: FL0001503 Major/minor: Major SIC code: 4911 (Electrical Services) Industrial Category: Electrical Services Design Flow: Not reported Average Flow: 359 mgd for Outfall D-001 (average of maximum monthly values from 2006 through 2011) Receiving Water: South Fork of New River and Dania Cutoff Canal

Description Florida Power and Light, Lauderdale Plant is an electrical generating plant consisting of two natural gas and oil powered units with a winter net capacity of 960 megawatts. Wastewater from this facility includes once-through cooling water, boiler blowdown, RO concentrate, metal cleaning wastes and pretreated oily wastewater. Florida Power and Light, Lauderdale Plant discharges the majority of its effluent to an onsite canal flowing into a once-through cooling pond. Effluent from the cooling pond is discharged through Outfall D-001 to the South Fork of New River, which is a Class III marine surface water connected to coastal waters. However, stormwater runoff from the equipment area stormwater and intake screen washwater and strainer backwash water are discharged through Outfalls D-0B1 and D-009, respectively, to the Dania Cutoff Canal, located immediately south of the facility. Once-through condenser cooling water is discharged to the onsite canal and then the cooling pond via Internal Outfalls I-011A and I-011B. The process water treatment system provides treated water from onsite wells for combustion turbine steam injection, heat recovery steam generator (HRSG) makeup, pump seal water, evaporative coolers, and HRSG chemical cleaning. Activated carbon pressure filters treat the source water to remove organic materials and suspended solids before removal of dissolved solids in the RO units. After RO treatment, the water flows through a de-gasifier to remove carbon dioxide followed by a mix-bed demineralizer for final polishing. The facility neutralizes RO concentrate and demineralizer regeneration wastewater from the processes water treatment system prior to discharge through Internal Outfalls I-01E and I-012, respectively, to the onsite canal and thence the cooling pond. Oily stormwater runoff is collected from the transformer area runoff and fuel oil storage, and diverted to the oily wastewater surge basin, where a separator removes free oils/grease. If required, the water passes through dissolved air flotation separation to remove emulsified oils. The treated effluent is combined with other non-oily wastewaters, which include HRSG blowdown and chemical cleaning rinse. The combined wastewaters are treated by the facility’s wastewater treatment system, consisting of a wastewater equalization basin, package clarifier (a flash/floc mix tank and settling compartment plus chemical addition, if necessary), three parallel duel medial gravity filters, and pH adjustment tanks. The facility discharges the treated wastewaters through Outfall I-013 to the onsite canal and thence the cooling pond. HRSG blowdown is routed to a flash tank where much of the water flashes to steam and the remaining boiler blowdown is treated by the wastewater treatment system. During various maintenance activities, HRSG blowdown may bypass the wastewater treatment system for direct discharge to the onsite canal through Internal Outfalls I-016A and I-016B. The infrequent cleaning of the HRSG to remove corrosion and scale (once every 3 to 5 years for each unit) generates HRSG chemical cleaning rinse wastewaters. These wastewaters are batch treated in the13

wastewater treatment system separately from other wastewaters. Due to the large volume of wastewater associated with each cleaning event (approximately 500,000 gallons), a separate lined equalization basin is used to collect this wastewater prior to the treatment. Treated HRSG chemical cleaning rinse water is discharged through Internal Outfall I-015 to the onsite canal and thence the cooling pond. Stormwater runoff from the equipment area discharges through either Outfall D-0B1 to the Dania Cutoff Canal or Internal Outfall I-1B2 to the onsite canal and thence the cooling pond. Stormwater runoff from other areas discharges to the cooling canal and then the cooling pond through Internal Outfall I-1B3. Temporary dewatering activities may be required during below ground construction (no description of construction activities is provided by the facility permit) and release water will be discharged through Internal Outfall I-01D to the onsite canal and thence the cooling pond. Summary of Effluent Data and Limits TN and TP data are not available from EPA’s ICIS-NPDES database. However, a laboratory report indicates that in 2008, TN concentrations were approximately 1.22 mg/L and TP concentrations were approximately 0.026 mg/L (FDEP, 2008b) for Outfall D-001. There are no effluent limits for TN and TP in the current permit. Exhibit 4 summarizes these data. Exhibit 4: Effluent Data Summary, Florida Power and Light, Fort Lauderdale Plant

Potential Incremental Impacts Florida Power and Light, Fort Lauderdale Plant discharges to coastal waters, for which EPA has proposed only chlorophyll-a criterion. While there are no TN and TP criteria, EPA assumes that the Florida Power and Light would be required to meet the concentrations associated with economically feasible treatment (i.e., 3 mg/L for TN and 0.1 mg/L for TP) to reduce the potential for exceeding the chlorophyll-a criterion. Thus, based on available effluent data, incremental controls and costs under the proposed rule are unlikely.14 

### Florida Power and Light, Riviera Beach Energy Center NPDES permit number: FL0001546 Major/minor: Major SIC code: 4911 (Electrical Services) Industrial Category: Electrical Services Design Flow: 599 mgd Average Flow: Not reported Receiving Water: Lake Worth to the Intracoastal Waterways

Description Florida Power and Light, Riviera Beach Energy Center is an electric generating plant that recently ceased operations in preparation for the construction of the company’s Riviera Beach Next Generation Clean Energy Center (a large modernization project which will begin serving customers in 2014). The new, high-efficiency, combined-cycle natural gas turbines (1,250 megawatt in total capacity) 1 Unit 5 includes three gas turbines which will burn a variable combination of natural gas and No. 2 ultralow sulfur distillate fuel oil as a backup. The new equipment will have condenser once-through cooling water and auxiliary equipment cooling water systems that use water from Lake Worth Lagoon (a coastal marine waterbody). Auxiliary equipment cooling water and other wastewater streams will combine with the once-through cooling water for treatment by chlorination, followed by dechlorination prior to discharge through Outfall D-013 to Lake Worth, which ultimately discharges to the Intracoastal Waterway. Metal cleaning wastewater and RO membrane cleaning wastewater will be disposed of offsite. Other wastewater including washdown from cleaning and maintenance activities (which will be routed through an oil/water separator); RO reject; softener; multimedia filter backwash; low-volume and metal cleaning wastewater; and combined blowdown (from the Heat Recovery Steam Generators and Evaporative Coolers) will all ultimately discharge through internal outfalls to Outfall D-013 as well. When possible, some of the blowdown wastewaters will be reused as make-up water to the onsite water treatment system. Equipment area stormwater will be routed through an oil/water separator and then to a series of onsite retention ponds before discharge. All surface water will discharge to the Intracoastal Waterway (through Outfalls D-009, D-012, and D-013). Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this facility. Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 0.55 mg/L and 0.067 mg/L, respectively, for the North Lake Worth Lagoon segment (Segment ID 1201). Florida Power and Light, Riviera Beach Energy Center is not currently discharging due to construction, and is not scheduled to resume operations until 2014. In addition, given the lack of permit requirements and the nature of the wastewater (e.g., mainly once-through cooling water), RP and revised effluent limits for TN or TP under the proposed rule are unlikely even once the facility opens. Thus, incremental compliance costs are likely minimal.

### Florida Power and Light, St. Lucie Power Plant NPDES permit number: FL0002208 Major/minor: Major SIC code: 4911 (Electrical Services) Industrial Category: Electrical Services Design Flow: 1,478 mgd Average Flow: 1,386 mgd (average of maximum monthly values from 2006 through 2011) Receiving Water: Atlantic Ocean

Description Florida Power and Light, St. Lucie Power Plant is a power plant with two nuclear powered steam electricgenerating units with a combined capacity of 1,700 megawatts. The facility discharges noncontact oncethrough condenser cooling water and auxiliary equipment cooling water, which are treated by chlorination. Low volume wastes (including water treatment system wastewater, steam generator/boiler blowdown, and equipment area floor drainage), non-radioactive wastes/liquid radiation waste, and industrial stormwater are treated by chemical/physical processes including neutralization, settling, ion exchange and microfiltration. Stormwater and intake screen washwater are discharged without treatment. All surface water effluent is discharged to the Atlantic Ocean via onsite drainage canals through Outfall D-001. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. However, laboratory reports indicate that in 2010, TN concentrations were approximately 0.356 mg/L and TP concentrations were approximately 0.021 mg/L for Outfall D-001 (FDEP, 2010a). There are no effluent limits for TN and TP in the current permit. Exhibit 5 summarizes these data. Exhibit 5: Effluent Data Summary, Florida Power and Light, St. Lucie Plant

Potential Incremental Impacts EPA is proposing a chlorophyll-a criterion for coastal waters. While there are no TN and TP criteria, EPA assumes that the Florida Power and Light, St. Lucie Power Plant would be required to meet the concentrations associated with economically feasible treatment (i.e., 3 mg/L for TN and 0.1 mg/L for TP) to reduce the potential for exceeding the chlorophyll-a criterion. Thus, based on available effluent data, incremental controls and costs under the proposed rule are unlikely.16 

### Gulf Power Company, Lansing Smith Power Plant NPDES permit number: FL0002267 Major/minor: Major SIC code: 4911 (Electrical Services) Industrial Category: Electrical Services Design Flow: 273.6 mgd for Outfall D-001 Average Flow: Not reported Receiving Water: Warren Bayou and Alligator Bayou

Description Gulf Power Company, Lansing Smith Power Plant is an electric generating plant with a total rating of 924 megawatts. The facility includes two fossil fuel-fired steam generators (Units 1 and 2), two gas-fired combined cycle combustion turbine electrical generators each with a duct-fired heat recovery steam generator (Unit 3), and two combustion turbines. Units 1 and 2 utilize a primary fuel of pulverized coal with a distillate fuel oil back-up. Units 1 and 2 use once-through cooling water while Unit 3 uses a closed loop steam condenser cooling system cooling tower. Wastewater streams discharged to the onsite discharge canal include once-through cooling water from Units 1 and 2, cooling tower blowdown from a closed loop cooling system for Unit 3 through Internal Outfall I-017, ash pond overflow, and evaporative cooler blowdown and clean drain effluent from the turbine/boiler building. Collected stormwater is drained and released to the site runoff water system through transformer enclosure drains. The onsite discharge canal discharges through Outfall D-001 to the Warren Bayou. Numerous other wastewaters are discharged to the ash pond including include treated metal cleaning waste through Outfall I-015, treated domestic wastewater through Outfall I-01A, boiler blowdown, water treatment filter backwash, air preheater wash, ash and pyrite sluice, coal pile runoff, yard runoff, treated demineralizer regeneration waste, and other minor process and non-process waste streams. Demineralizer regeneration waste and metal cleaning waste are both neutralized and allowed to settle in a retention pond prior to discharge to the ash pond. As a secondary treatment, domestic wastewater is sent to an extended aeration package treatment plant prior to onsite recycling at the ash pond. Certain types of demineralizer waste (green sand filter backwash, multimedia filter backwash, and RO concentrate) are routed to a stormwater sump prior to discharge to the ash pond. Gas turbine and equipment wastes pass through an oil-water separator; the wastewater drains to the site wastewater sump prior to discharge to the ash pond. Ash pond overflow is continuously discharged through Internal OutfallI-01C to the onsite discharge canal. Emergency ash pond overflow may be discharged through Outfall D00D to the onsite intake canal in the Alligator Bayou. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. However, a laboratory report indicates that in 2011, TN concentrations were approximately 0.253 mg/L and TP concentrations were approximately 0.17 mg/L for Outfall D-001 (FDEP, 2011a). There are no effluent limits for TN and TP in the current permit. Exhibit 6 summarizes these data.17

Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 0.22 mg/L and 0.014 mg/L, respectively, for the Warren Bayou and Alligator Bayou in the North Bay segment (Segment ID 0407) of the St. Andrews Bay estuary system. Analysis of a single year of data (2008) from FDEP’s IWR database indicates that TN concentrations in the segment are above the proposed criterion and TP concentrations are below the proposed criterion. However, because the data are limited and no mixing zones are described in the permit, EPA conservatively (i.e., erring on the side of estimating greater impact and higher costs under the proposed rule) assumes no dilution is available. Error! Reference source not found. summarizes the RP analysis and estimated projected effluent limits for the facility.

Proposed annual geometric mean criterion. 3. Represents criterion end-of-pipe because the ambient data are limited and the existing permit does not provide dilution for effluent limits.

The exhibit indicates that the facility would likely have RP under the proposed rule for both TN and TP because the average effluent concentrations exceed the proposed criteria. Based on average effluent concentrations, the facility would not be in compliance with the projected effluent limit for TN or TP and may need to implement some incremental level of control. However, due to the extremely low TN and TP criteria, there is significant uncertainty as to whether the projected effluent limits are feasible to attain. Thus, EPA estimates costs based on the assumption of a variance from meeting effluent limits based on criteria end-of-pipe. While existing TN concentrations are already relatively low, additional reductions in TP could be achieved through cost-effective treatment controls. Thus, EPA estimates incremental compliance costs based on installation of chemical precipitation followed by filtration as a condition of the variance (i.e., lowest levels feasible). Capital and O&M unit costs associated with this treatment could be $0.32/gpd and $238/MG, respectively. EPA assumes that treatment would be required only for internal outfalls likely to contain nutrients, specifically the ash pond overflow (internal Outfall I-01C) and domestic wastewater treatment18

effluent (internal Outfall I-01A), and not for the other wastewater components (e.g., once-through cooling water). The facility’s permit specifies a design flow of 0.0075 mgd for internal Outfall I-O1A, but does not report design flows from which to estimate total capital costs for internal Outfall I-01C. Therefore, to estimate capital costs, EPA uses the 90th percentile maximum monthly flow from 2006 through 2011 to approximate the necessary design flow (5.01 mgd for internal Outfall I-01C). Based on these flows (approximated to be 5.01 mgd), total capital costs could be approximately $1.6 million. During the last 5 years, average maximum monthly flows have been approximately 4.36 mgd for internal Outfall I-01C and are assumed to equal the design flow for internal Outfall I-01A (0.0075 mgd). Thus, based on these flows (approximated to be 4.36 mgd) and assuming operation of the treatment units 365 days per year, O&M costs could be approximately $0.38 million. Total annual costs would be $0.53 million based on annualizing capital costs at 7% over 20 years and adding annual O&M. Exhibit 8 summarizes these costs.

### Progress Energy Florida, Anclote Plant NPDES permit number: FL0002992 Major/minor: Major SIC code: 4911 (Electrical Services) Industrial Category: Electrical Services Design Flow: 821.7 mgd for Outfall D-004 Average Flow: Not reported for D-004; 1,083 mgd for I-001; 607 mgd for I-003; 0.18 mgd for I-006 (average of average value from 2006 through 2011) Receiving Water: Anclote Sound

Description Progress Energy Florida, Anclote Plant is an electric generating station with a two oil-fired steam units with a total capacity rating of 1,112 megawatts. The facility receives once-through cooling water from an onsite canal connected to the Anclote Sound. Once-through cooling water is discharged to the plant’s onsite discharge canal without treatment through Internal Outfalls I-001 and I-002. During certain times of the year, the cooling water may be sent to two non-recirculating cooling towers to reduce plant discharge temperature in which case the water used in cooling towers is treated with a biocide and then dehalogenated before discharge. An additional stream used for temperature dilution may be discharged to the discharge canal through Internal Outfall I-003. Cooling tower blowdown may be discharged to the discharge canal through Internal Outfall I-005. The combined wastewater is returned to the Anclote Sound via through the discharge canal via External Outfall D-004. Stormwater may be discharged to the intake canal from Internal Outfall I-006. All other wastewater treatment is discharged into two onsite percolation/evaporation ponds without surface water discharge. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. However, a laboratory report indicates that in 2009, TN concentrations were approximately 0.53 mg/L and TP concentrations were approximately 0.024 mg/L for Outfall D-004 (FDEP, 2009a). There are no effluent limits for TN and TP in the current permit. Exhibit 9 summarizes these data. Exhibit 9: Effluent Data Summary, Progress Energy Florida, Anclote Plant

Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 0.31 mg/L and 0.011 mg/L, respectively, for the Anclote Offshore segment (Segment ID 0805) of the Anclote Sound, located in the Spring Coast watershed.20

Analysis of FDEP’s IWR data for the segment indicates that the water may not be in compliance with the proposed criteria. Thus, EPA assumes the discharger would not receive dilution under the proposed rule. Exhibit 10 summarizes the RP analysis and estimated projected effluent limits for the facility.

The exhibit indicates that the facility would likely have RP under the proposed rule for both TN and TP because the average effluent concentrations exceed the proposed criteria. Based on average effluent concentrations, the facility would not be in compliance with the projected effluent limit for TN or TP and may need to implement some incremental level of control. However, due to the extremely low TN and TP criteria, there is significant uncertainty as to whether the projected effluent limits are technologically or economically feasible to attain. In addition, influent data for cooling water from EPA’s ICIS-NPDES database indicates that average nutrient concentrations of the influent water are 0.8 mg/L for TN and 0.189 mg/L for TP (represents an average of three maximum monthly values from 2011), which exceed the effluent concentrations for both TN and TP observed in 2009 (FDEP, 2009a). Thus, it is possible that the majority of the nutrients in the effluent are due to nutrients in the influent waters. Further, EPA (2009) indicates that nutrients are not likely present in once-through cooling water and cooling tower blowdown. Given the lack of existing permit requirements, the existing low TN and TP effluent concentrations and higher influent concentrations, and the nature of the wastewater (i.e., mainly once-through cooling water), it is unlikely that the plant is a significant contributor of nutrients. Thus, EPA assumes that the discharger would receive intake credits and have effluent limits based on not increasing nutrients in the effluent, resulting in no incremental controls.21 

### Progress Energy Florida, Crystal River Plant Units 1, 2, and 3 NPDES permit number: FL0000159 Major/minor: Major SIC code: 4911(Electrical Services) Industrial Category: Electrical Services Design Flow: 1,898 mgd Average Flow: 1,281 mgd (average of average monthly values from 2006 through 2010) Receiving Water: Onsite discharge canal to the Springs Coast watershed in the Gulf of Mexico Description Progress Energy Florida, Crystal River Plant Units 1, 2, and 3 discharges wastewater from two electric generating, pulverized coal powered units (Units 1 and 2), and a nuclear powered unit (Unit 3) with a combined capacity of 1,855 megawatts. Unit 3 in not currently in operation due to structural repairs and is not expected to be operational until 2014. Units 4 and 5 within the complex are covered under a separate NPDES permit (FL0036366). Units 1-5 in this complex receive water once through cooling water through an onsite intake canal and discharge effluent to an onsite discharge canal. Both the onsite intake and discharge canals are connected to the Springs Coast in the Gulf of Mexico.Progress Energy Florida’s Crystal River Plant performs filtration and or other biocide treatment of oncethrough noncontact condenser cooling water the following treatment on once-through cooling water. The facility performs neutralization, settling, filtration and/or oil/water separation for low volume wastewaters and metal cleaning wastes. Progress Energy Florida’s Crystal River Plant discharges once-through cooling water from Units 1, 2 and 3 through Outfalls D-011, D-012 and D-013, respectively, to the onsite discharge canal. Once-through cooling water receives additional cooling through the helper cooling towers system, which is then discharged into the site discharge canal through D-071 and D-072. Intake screen washwater is discharged though Outfalls D-091, D-092, D-093, and D-094 to the onsite discharge canal. An emergency backup water supply pump for U.S. Nuclear Regulatory Commission testing may discharge to the onsite intake canal through Outfall D-095. Stormwater is discharged from the facility through Outfalls D-100, D-200, D-300, D-400, D-500 and D-600 to either the onsite intake canal or onsite discharge canal. Progress Energy Florida’s Crystal River Plant discharges non-cooling wastewaters including effluent from the industrial wastewater pond system through D-C2R to the onsite discharge canal. Numerous effluents are discharged through Outfall D-00F to the onsite discharge canal. The primary effluent in Outfall D-00F is effluent from the nuclear services and decay heat seawater system, however, this stream is combined with low volume effluents from Internal Outfall I-0FE, effluent from the laundry and shower sump tanks; Internal Outfall I-0FE, effluent from the regeneration waste neutralization tank (which includes metal cleaning waste); and effluent from the evaporator condensate storage tank and condensate system (these streams are not separately monitored). Coal pile runoff is discharged to a nearby salt march through Outfall D-00H. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. However, a laboratory report indicates that in 2009, TN concentrations were approximately 0.555 mg/L and TP concentrations were approximately 0.048 mg/L for Outfall D-072 and TN concentrations were approximately 0.722 mg/L and TP concentrations were approximately 0.093 mg/L for Outfall D-00F.22

Represents criterion end-of-pipe because analysis of the ambient data indicates that the segment may not be in compliance with the proposed criteria.

The exhibit indicates that the facility would likely have RP under the proposed rule for both TN and TP for both outfalls because the average effluent concentrations exceed the proposed criteria. Based on average effluent concentrations, the facility would not be in compliance with the projected effluent limit for TN or TP and may need to implement some incremental level of control. Outfall D-072 is mainly once-through cooling water which is not likely to contain significant nutrient concentrations based on data from U.S. EPA (2009). The intake water is from the Springs Coast, with nutrient concentrations similar to those in the discharge (see Exhibit 12 above). Thus, EPA assumes that the discharger would likely receive intake credits for compliance with effluent limits and incremental controls and costs are not likely.23

For Outfall D-00F, there is significant uncertainty as to whether the projected effluent limits are technologically or economically feasible to attain. Thus, EPA estimates costs based on the assumption of a variance from meeting effluent limits based on criteria end-of-pipe. While existing TN concentrations are already relatively low, additional reductions in TP could be achieved through cost-effective treatment controls. Thus, EPA estimated incremental compliance costs based on installation of chemical precipitation followed by filtration as a condition of the variance (i.e., lowest levels feasible). Capital and O&M unit costs associated with this treatment could be $0.32/gpd and $238/MG, respectively. EPA assumes that treatment would be required only on effluent from the laundry and shower sump tanks (Internal Outfall I-0FE) and effluent from the regeneration waste neutralization tank (Internal Outfall I-0FG) and not the other wastewater components of Outfall D-00F (i.e., mainly nuclear services and decay heat seawater system effluent) because it is not likely to contain nutrients. The facility’s permit does not report design flows from which to estimate total capital costs. Therefore, to estimate capital costs, EPA used the 90th percentile maximum monthly flow for both outfalls from 2006 through 2011 to approximate the necessary design flow (0.0015 mgd for Outfall I-0FE and 0.0831 mgd for Outfall I-0FG). Based on these flows, total capital costs would be approximately $0.027 million. During the last 5 years, average maximum monthly flows for Outfall I-0FE and Outfall I-09FG have been 0.0010 mgd and 0.0796 mgd, respectively. Thus, based on these flows and assuming operation of the treatment units 365 days per year, O&M costs could be approximately $0.0070 million. Total annual costs would be $0.0096 million based on annualizing capital costs at 7% over 20 years and adding annual O&M. Exhibit 13 summarizes these costs.

Average flow multiplied by unit cost of $238/MG for chemical precipitation with filtration and the number of operating days per year (365 days). 3. Capital costs annualized at 7% over 20 years plus annual O&M.

For the remaining external outfalls, there are no effluent data from which to assess compliance and the facility does not have existing effluent limits or monitoring requirements for TN or TP. Given the lack of existing permit requirements, potential for intake credits, and the nature of the wastewater (i.e., mainly once-through cooling water and stormwater), it is unlikely that the facility would have reasonable potential under the proposed rule for the remaining external outfalls. Thus, incremental compliance costs are likely zero for the remaining external outfalls.24

Description Progress Energy Florida, Crystal River Plant Units 4 and 5 discharge wastewater from of two electric generating, coal-fired units (Units 4 and 5) with a total capacity rating of 1,390 megawatts. Units 1, 2 and 3 within the complex are covered under a separate NPDES permit (FL0000159). Units 1-5 receive water once through cooling water through an onsite intake canal and discharge effluent to an onsite discharge canal. Both the onsite intake and discharge canals are connected to the Springs Coast in the Gulf of Mexico. Progress Energy Florida, Crystal River Plant Units 4 and 5 performs chlorination in the noncontact recirculating cooling tower water from Units 4 and 5. Noncontact recirculating cooling tower blowdown is discharged through Outfalls D-074 and D-075 to the onsite discharge canal. Stormwater runoff from the coal storage area, ash landfill runoff, ash sluice and dewatering system, and fly/bottom ash transport truck rinsate is treated by sedimentation in the collection areas. In the rare event of an overflow of the collection areas, runoff collected from the coal storage area and ash landfill area are discharged by Internal Outfalls I-CHO and I-C40, respectively, through Outfall D-0CO to the onsite discharge canal. Summary of Effluent Data and Limits TN and TP data are not available from EPA’s ICIS-NPDES database. However, a laboratory report indicates that in 2004, TN concentrations were approximately 0.53 mg/L and TP concentrations were approximately 0.072 mg/L for Outfall D-075 (FDEP, 2004a).

Thus, EPA assumes that the discharger would likely receive intake credits for compliance with effluent limits and incremental controls and costs are not likely. For the remaining external outfalls, there are no effluent data from which to assess compliance and Progress Energy does not have existing effluent limits or monitoring requirements for TN or TP at the Crystal River Plant Units 4 and 5.

### Vero Beach Municipal Power Plant NPDES permit number: FL0002984 Major/minor: Major SIC code: 4911 (Electrical Services) Industrial Category: Electrical Services Design Flow: 217 mgd Average Flow: 5.7 mgd for outfall D-011, 12.4 mgd for outfall D-012 and 34.4 mgd for outfall D-013 (average of average monthly values from 2006 through 2011) Receiving Water: Indian River Lagoon

Description Vero Beach Municipal Power Plant is an electric generating plant with five units and a total capacity of 157 megawatts. The plant contains four steam electric generating units (Units 1, 2, 3 and 4) and a combined-cycle gas turbine unit (Unit 5). Each of the steam electric units can burn a variable combination of No. 2, No. 4 and No. 6 fuel oil and natural gas.Units 1, 2 and 3 are permitted to draw a maximum of 217 mgd from the Indian River Lagoon as oncethrough noncontact cooling water and discharge it back into the Indian River Lagoon with no treatment through Outfalls D-011, D-012, and D-013. Unit 4 obtains treated wastewater effluent from the Vero Beach Waste Water Treatment Plant to use for its cooling tower. The cooling tower blowdown is returned to the wastewater treatment plant. Unit 5 is equipped with a closed-loop auxiliary cooling water system. Units 4 and 5 are not permitted to discharge to Florida waters. Uncontaminated stormwater is also discharged to the Indian River Lagoon through Outfalls D-0S1, D-0S2, D-0S3, and D-0S6. Stormwater discharge from fuel oil tanks 1 and 2 bermed areas are discharged to the Indian River via Outfall D-00B. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. However, a laboratory report indicates that in 2004, TN concentrations were approximately 0.2 mg/L and there was no detection for phosphorous for Outfall D-00B (FDEP, 2004b). There are no effluent limits for TN and TP in the current permit. Exhibit 16 summarizes these data. Exhibit 16: Effluent Data Summary, Vero Beach Municipal Power Plant

The exhibit indicates that the facility does not have RP because effluent concentrations for TN and TP are below the proposed criteria. Thus, EPA assumes that the facility would not incur incremental costs associated with TN or TP reductions. In addition, for those outfalls for which data are not available, EPA assumes that incremental compliances costs are not likely because the facility is not considered a source of nutrients and does not have nutrient loading or effluent targets in the Indian River TMDL (Gao, 2009). Also, the lack of existing permit requirements and the nature of the wastewater (e.g., mainly once-through cooling water and stormwater), suggest that the facility is not likely to have RP under the proposed.28



## Food Tropicana Manufacturing Company, Inc NPDES permit number: FL0000043 Major/minor: Major SIC code: 0174 (Citrus Fruits) Industrial Category: Food Design Flow: 2.26 mgd Average Flow: No discharge since 2003 Receiving Water: Manatee River

Description Tropicana Manufacturing Company, Inc. operates a citrus juice processing plant with processes fresh fruit during the harvesting season (November through June) and packages the juice on a year-round basis. The process wastewater from the production facility is treated in an onsite, multi-stage wastewater treatment plant which consists of equalization, dissolved air flotation, anaerobic bioreactors, pH adjustment, and 2nd stage activated sludge (aeration and secondary clarification), and tertiary dissolved air flotation. Treated effluent is stored or discharged to an underground injection well or Manatee River. Summary of Effluent Data and Limits The facility has not discharged in the last five years; thus, there are no effluent data for TN and TP. However, the discharge has an annual loading limit for TN of 9.125 tons/year based on a 5-year rolling average with a 1-year maximum load not to exceed 13.6875 tons. Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 0.62 mg/L and 0.115 mg/L, respectively, for the Manatee River (Segment ID 0906). However, because the facility has not discharged within the last five years, EPA assumes that it would not have RP under the proposed rule and would be unlikely to incur incremental control costs.29

Description Anheuser Busch Inc. operates a land application system that receives untreated and/or pretreated brewery liquor as a nutrient enrichment to grow turf and forage crops on a 320-acre site. The land application site drains to an interconnected pond system composed of two ponds: North Borrow Pit and South Borrow Pit. North Borrow Pit drains to South Borrow Pit, which discharges via Outfall D-001 to Little Cedar Creek, and thence to the Broward River and ultimately to the Saint Johns River.

Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 1.09 mg/L and 0.108 mg/L, respectively, for the St. Johns River estuary (Segment ID 1802). Anheuser Busch Inc. is already covered under the Lower St. Johns River TMDL and Basin Management Action Plan (BMAP). EPA assumes that the TMDL targets would be adopted as SSAC. FDEP gave the discharger a TN WLA that represented a 49% decrease in TN. To reduce effluent nutrient loads, in 2006, Anheuser Busch improved/modified the site nutrient management plan and increased the crop area to which they land applied a portion of the wastewater to reduce the nutrient load per acre (Busby, 2009). Thus, EPA assumes that the discharger would not be required to implement additional controls for compliance with TN limits under the proposed rule. Analysis of FDEP’s IWR data for the segment indicates that the water may not be in compliance with the proposed TP criterion. Thus, EPA assumes the discharger would not receive dilution under the proposed rule. Exhibit 19 summarizes the RP analysis and estimated projected effluent limits for TP for the facility.30

The exhibit indicates that the facility would likely have RP under the proposed rule for TP because the average effluent concentration exceeds the proposed criteria. Based on average effluent concentrations, the facility would not be in compliance with the projected effluent limit for TP and may need to implement some incremental level of control. Due to a lack of site-specific facility operations and treatment data, it is uncertain whether additional improvements or modifications similar to those made to reduce TN concentrations could be made to reduce TP concentrations. However, to be conservative (i.e., erring on the side of estimating greater impact and higher costs under the proposed rule), EPA estimates costs to meet the potential TP levels based on installing chemical precipitation followed by filtration. Capital and O&M unit costs could be $0.32/gpd and $238/MG, respectively. Based on a design flow of 2.4 mgd, total capital costs could be approximately $0.77 million. During the last 5 years, average maximum monthly flows have been approximately 1.02 mgd. Thus, assuming operation of the treatment units 365 days per year, O&M costs could be approximately $0.089 million. Total annual costs would be $0.16 million based on annualizing capital costs at 7% over 20 years and adding annual O&M. Exhibit 20 summarizes these costs.

Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 0.27 mg/L and 0.045 mg/L, respectively, for the Lower Amelia River (Segment ID 2002) in the St. Mary’s Estuary. There are limited data (two observations for TN and TP each from 2011) available for the segment in FDEP’s IWR database. This data indicates that the segment may not be in compliance with the proposed TN and TP criteria. Thus, EPA assumes the discharger would not receive dilution under the proposed rule. Exhibit 22 summarizes the RP analysis and estimated projected effluent limits for TN and TP for the facility.32

Proposed annual geometric mean criterion. 3. Represents criterion end-of-pipe because analysis of the ambient data indicates that the segment may not be in compliance with the proposed criteria.

The exhibit indicates that the facility would likely have RP under the proposed rule for TN and TP because the average effluent concentrations exceed the proposed criterion. Based on average effluent concentrations, the facility would not be in compliance with the projected effluent limit for TN or TP and may need to implement some incremental level of control. However, due to the low TN and TP criteria, there is significant uncertainty as to whether the projected effluent limits are feasible to attain. Thus, EPA estimates costs based on the assumption of a variance from meeting the projected effluent limits; the appendix provides analysis of an alternative treatment scenario. Because existing TN and TP discharge concentrations are high compared to levels that can be achieved with cost-effective treatment controls such as advanced biological nutrient removal (BNR), EPA assumes that the facility would need to reduce TN and TP as a condition of the variance (i.e., lowest levels feasible). Thus, EPA estimated incremental compliance costs based on installation of advanced BNR. Capital and O&M unit costs could be $1.30/gpd and $385/MG, respectively. Based on a design flow of 26.31 mgd, total capital costs could be approximately $36.0 million. During the last 5 years, average maximum monthly flows have been 16.8 mgd. Thus, to estimate O&M costs EPA used these average flows assuming operation of the treatment units 365 days per year at a cost of $2.5 million. Total annual costs would be $5.9 million based on annualizing capital costs at 7% over 20 years and adding annual O&M. Exhibit 23 summarizes these costs.

Description Smurfit Stone, Fernandina Beach Containerboard Mill produces unbleached Kraft linerboard through the following processes: wood preparation, pulping, pulp processing and chemical recovery, and paper and paperboard manufacturing, all of which contribute to production of wastewater. Wastewater treatment consists of a grit chamber, bar screen, primary clarifier, heat exchanger, cooling tower (for noncontact cooling water), pure oxygen activated sludge treatment system, and dual secondary clarifiers. The facility dewaters primary and secondary solids using screw presses and belt presses. The facility discharges to Lower Amelia River. Summary of Effluent Data and Limits Average monthly effluent data for TP are available from 2006 to 2010 from EPA’s ICIS-NPDES database. TN data are not available from EPA’s ICIS-NPDES database, however, the average total Kjeldahl nitrogen concentration from 2006 to 2010 is approximately 3.8 mg/L (based on 19 observations of the maximum monthly value). Total Kjeldahl nitrogen is the sum of organic nitrogen, and ammonia and ammonium as nitrogen, and can be used to estimate TN by adding the concentrations of nitrate and nitrite as nitrogen. A laboratory report for this facility indicates that nitrate and nitrite as nitrogen concentrations were insignificant (0.004 mg/L) relative to total Kjeldahl nitrogen levels (FDEP, 2009d). Thus, total Kjeldahl nitrogen levels can be used as a proxy for TN for this analysis. Exhibit 24 summarizes these data.

Description The facility generates pulp with an onsite recycling pulp operation or the purchase of bleached pulp. The Saint John’s River BMAP indicates that the facility changed from a pulp and paper mill to a recycling mill in the 1990s, reducing the volume of effluent. Wastewater treatment consists of grit removal, primary clarification, and aeration in two unlined holding ponds and an unlined aeration stabilization basin. The facility also includes an onsite landfill and sludge drying beds which process nonhazardous solid waste material from onsite operations and activities. The facility discharges treated process wastewater and sanitary wastewater to the Saint John’s River. Summary of Effluent Data and Limits

Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 1.09 mg/L and 0.108 mg/L, respectively, for the St. John’s River (Segment ID 1802). The facility is covered under the Lower St. John’s River TMDL and BMAP, which set targets for TN only. The BMAP indicates that no additional reductions are needed for compliance with the facility’s WLA (it has already achieved twice as many reductions as needed for the TMDL). Thus, assuming the existing TN TMDL target is adopted as a SSAC, there would be no incremental costs associated with TN reductions under the proposed rule. However, for TP, analysis of FDEP’s IWR data for the segment indicates that the water may not be in compliance with the proposed TP criterion. Thus, EPA assumes the discharger would not receive dilution under the proposed rule. Exhibit 28 summarizes the RP analysis and estimated projected effluent limits for TP for the facility.36

The exhibit indicates that the facility would likely have RP under the proposed rule for TP because the average effluent concentration exceeds the proposed criterion. Based on average effluent concentrations, the facility would not be in compliance with the projected effluent limit for TP and may need to implement some incremental level of control. However, due to a lack of site-specific facility operations and treatment data, it is uncertain whether additional improvements or modifications could be made to reduce TP concentrations. As such, EPA conservatively (i.e., erring on the side of estimating greater impact and higher costs under the proposed rule) estimates costs based on installation of chemical precipitation followed by filtration. Capital and O&M unit costs could be $0.32/gpd and $238/MG, respectively. Based on a design flow of 20 mgd, total capital costs could be approximately $6.4 million. During the last 5 years, average maximum monthly flows have been approximately 7.4 mgd. Thus, assuming operation of the treatment units 365 days per year, O&M costs could be approximately $0.64 million.

## Other BP Products North America, Port Everglades North and South Terminal NPDES permit number: FL0044148 Major/minor: Minor SIC code: 5171 (Petroleum Bulk Stations and Terminals) Industrial Category: Other Design Flow: 0.5 mgd for Outfall D-002 and 0.5 mgd for Outfall D-003 Average Flow: No discharges in the past five years Receiving Water: Intracoastal Waterway

Description BP Products North America, Port Everglades North and South Terminals are bulk petroleum storage and distribution facilities consisting of two separate north tank farm and south tank farm terminal sites. The north terminal operation includes four main storage tanks for unleaded gasoline and denatured ethanol (with a total storage capacity of 12 MG), a fifth decommissioned tank, and two smaller tanks (10,000 gallon) for petroleum contact water. The north terminal is surrounded by an unlined secondary containment area. The south terminal operation consists of three main storage tanks for unleaded gasoline and denatured ethanol (with a total storage capacity of 15 MG) and one smaller tank for petroleum contact water. The south terminal is surrounded by a lined secondary containment area and unlined retention-percolation pond (32,000 sq. ft.). The sites are connected allowing for the transmission of fuel products or wastewater between the two terminals. Hydrostatic test water and stormwater is discharged through Outfalls D-001 (north terminal) and D-002 (south terminal) to an unnamed drainage ditch. From the unnamed drainage ditch, the discharge proceeds to the Eller Drive ditch, and then to the Florida Power and Light cooling water discharge canal (which also receives effluent from Florida Power and Light, Lauderdale Plant, FL0001538, and other NPDES permitted dischargers), which ultimately discharges into the Intracoastal Waterway. Hydrostatic test water is normally discharged untreated, although the permit requires analysis prior to discharge to ensure that effluent limitations are met. Disposal of stormwater is normally by percolation and evaporation. However, stormwater may be discharged through the outfalls either without treatment if no oil sheen is present or after treatment with an oil/water separator. Petroleum contact water, including tank bottom water and loading rack runoff, is collected and ultimately hauled offsite for disposal. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. Potential Incremental Impacts BP Products North America, Port Everglades North and South Terminals discharges to coastal waters, for which EPA has proposed only chlorophyll-a criterion. While there are no TN and TP criteria, EPA assumes that BP Products North America would be required to meet the concentrations associated with economically feasible treatment (i.e., 3 mg/L for TN and 0.1 mg/L for TP) to reduce the potential for exceeding the chlorophyll-a criterion. However, BP Products North America does not have effluent limits or monitoring requirements for TN or TP at the Port Everglades North and South Terminals. Given the lack of permit requirements and the nature of the wastewater (i.e., hydrostatic test water and stormwater) and that no discharges have occurred in the past five years, it is unlikely that the facility would have reasonable potential under the proposed rule. Thus, incremental compliance costs are likely zero.38 

### Chevron Products Company, Panama City Terminal NPDES permit number: FL0175480 Major/minor: Minor SIC code: 5171 (Petroleum Bulk Stations and Terminals) Industrial Category: Other Design Flow: Not reported Average Flow: No discharges in the past five years Receiving Water: St. Andrews Bay

Description Chevron Products Company, Panama City Terminal is a bulk petroleum storage terminal which receives, stores and transfers petroleum products including gasoline, jet fuel, diesel fuel and petroleum additives. The wastewater consists of petroleum contact water generated from stormwater runoff, tanker truck loading rack wash down, storage tank water draw off and groundwater collection. Combined wastewaters are treated with an oil/water phase separator and are then disposed of in an onsite 3.4 million gallon evaporation storage tank. The tank includes an internal spray system which accelerates evaporation and volatilization of organics. Wastewater is only discharged in the event of prolonged rainfall that causes the evaporation storage tank to overflow. In case of such an event, the excess wastewater is discharged into St. Andrews Bay. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 0.19 mg/L and 0.016 mg/L, respectively, for the Western St. Andrews Bay (Segment ID 0404) in the St. Andrews Bay Estuary. However, there are no effluent data from which to assess compliance, and Chevron Products Company does not have existing effluent limits or monitoring requirements for TN or TP from the Panama City Terminal. Given the lack of existing permit requirements, the nature of the wastewater (e.g., stormwater), and that no discharges have occurred in the past five years, it is unlikely that the facility would have reasonable potential under the proposed rule. Thus, EPA assumes that incremental control costs under the proposed rule are likely zero.39

Average Flow: No discharges in the past five years Receiving Water: Port Everglades Turning Basin

Description Chevron Products Company, Port Everglades Terminal is a bulk petroleum storage and distribution facility consisting of two separate east field tank farm and west field tank farm sites. At the east field, there are 12 existing (three are being renovated) and two new major aboveground product storage tanks units under construction. The west field consists of three existing plus two new units under construction. The existing storage tanks store unleaded gasoline, jet fuel, and crude oil (with capacities ranging from 0.4 to 5.8 MG); while the two new tanks at the east field will store ethanol. The fields also include smaller tanks (six at the east field and three at the west) for “Transmix” (off-spec recovered hydrocarbons), petroleum contact water, and fuel additives (all tanks are less than 1,000 barrels). Secondary containment for both sites involves earthen dikes and a concrete wall surrounding the unlined basins. The west field also contains a retention pond to collect only the noncontact stormwater runoff. Hydrostatic test water is discharged through Outfalls D-001 (eastern field) and D-002 (western field) to a storm sewer system that empties into Slip No. 1 at the Port Everglades Turning Basin. Hydrostatic test water is normally discharged untreated, though the permit requires analysis prior to discharge to ensure that effluent limitations are met. Diked area stormwater is retained onsite and disposed of via percolation; however, Chevron Products Company intends to obtain a separate Multi-Sector Generic Permit in the future to authorize stormwater discharge. Oil/water separators and gravity settling pits treat petroleum contact water, which includes tank bottom water and loading rack runoff. Treated petroleum contact is stored onsite and ultimately hauled offsite for disposal. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. Potential Incremental Impacts Chevron Products Company, Port Everglades Terminal discharges to coastal waters, for which EPA has proposed only chlorophyll-a criterion. While there are no TN and TP criteria, EPA assumes that the Chevron Products Company would be required to meet the concentrations associated with economically feasible treatment (i.e., 3 mg/L for TN and 0.1 mg/L for TP) to reduce the potential for exceeding the chlorophyll-a criterion. However, Chevron Products Company does not have effluent limits or monitoring requirements for TN or TP at the Port Everglades Terminal. Given the lack of permit requirements and the nature of the wastewater (i.e., hydrostatic test water and stormwater) and that no discharges have occurred in the past five years, it is unlikely that the facility would have reasonable potential under the proposed rule.

Description Coastal Terminals LLC, Port Everglades Terminal is a bulk petroleum products storage and distribution facility at Port Everglades consisting of 33 aboveground tanks at the North Terminal site. The 25 major tanks (with capacities ranging from 0.2 to 5.0 MG) store various petroleum products including unleaded gasoline, diesel fuel, No. 6 fuel oil, jet fuel, crude oil, and asphalt. Another seven smaller tanks (with capacities below 30,000 gallon) store fuel additives and the remaining tank (0.3 MG) is for petroleum contact water. The tank farm is surrounded by earthen dikes in an unlined basin. Hydrostatic test water is discharged through Outfalls D-001 (eastern outfall) and D-002 (western outfall) to an offsite storm sewer, which ultimately discharges into the Port Everglades Turning Basin. Hydrostatic test water is normally discharged untreated, although the permit requires analysis prior to discharge to ensure that effluent limitations are met. If necessary, portable water treatment equipment (e.g., diatomaceous earth filters) may be used to reduce the particular pollutant(s) of concern; however the effluent total residual chlorine level is usually reduced by exposure to the atmosphere during transport to the outfall via overland flow and across the detention pond. Outfall D-002 is the preferred outfall as its location allows for further treatment and percolation-recharge. Petroleum contact water, including tank bottom water and loading rack runoff, is collected and ultimately hauled offsite for disposal. Stormwater is normally disposed of by percolation and evaporation, however, stormwater discharge is allowed by a separate Multi-Sector Generic Permit.

Description CSXT Moncrief Rail Yard and Fruit Growers Express Yard is a rail yard which provides train classification, car switching, and locomotive re-fueling (CSX Transportation Inc. Moncrief Rail Yard) as well as car repair, blasting, and painting (Fruit Growers Express Rail Yard). The rail yards contain a common groundwater remediation system for chlorinated organic contaminants, polynuclear aromatic hydrocarbons and volatile organic contaminants. The remediation system treats the contaminatedgroundwater by air stripping from recovery wells. Treated wastewater is discharged through Outfall D001into McCoys Creek, which ultimately drains to Lower St Johns River. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 1.09 mg/L and 0.108 mg/L, respectively, for the Trout River (Segment ID 1802) in the St. Johns River Estuary. However, there are no effluent data from which to assess compliance, and the CSXT Moncrief Rail Yard and Fruit Growers Express Yard does not have existing effluent limits or monitoring requirements for TN or TP. Given the lack of existing permit requirements and that no discharges have been recorded in the past five years, it is unlikely that this facility would have reasonable potential under the proposed rule.

Description ExxonMobil Oil Corporation, Port Everglades North and South Terminals are bulk petroleum storage and distribution facilities consisting of two separate north tank farm and south tank farm sites. The north tank farm includes five main storage tanks for petroleum products (with a combined storage capacity of 9.2 MG); two smaller storage tanks for petroleum contact waters. The north tank farm is surrounded by an unlined containment basin area. The south tank farm consists of four main storage tanks for petroleum products (with a combined storage capacity of 12.2 MG) and two smaller storage tanks for petroleum contact water. The south tank farm is surrounded by a lined containment basin area. The north tank farm discharges hydrostatic tank test water and stormwater through Outfall D-001 to a storm sewer that ultimately empties into Slip No. 1 at Port Everglades Turning Basin, which is contiguous to the Intracoastal Waterway. Stormwater is usually disposed of via percolation with the containment area, but may be discharged through D-001. The south tank farm discharges hydrostatic tank test water and stormwater through Outfall D-003 to an unnamed drainage ditch. From the unnamed drainage ditch, the discharge proceeds to the Eller Drive ditch, thence to the FP&L cooling water discharge canal (which also receives effluent from Florida Power and Light, Lauderdale Plant, FL0001538, and other NPDES permitted dischargers), which ultimately discharges into the Intracoastal Waterway. If and oil sheen is present, an oil/water separator treats stormwater from the diked areas, otherwise, this stormwater is discharged without treatment. Both tank farms normally discharge hydrostatic test water without treatment, though the permit requires analysis prior to discharge to ensure that effluent limitations are met. The facility collects petroleum contact water, including tank bottom water and loading rack runoff, which is ultimately hauled offsite for disposal.

### Florida Atlantic University Sea Tech Facility NPDES permit number: FL0178870 Major/minor: Minor SIC code: 8733 (Noncommercial Research Organizations) Industrial Category: Other Design Flow: 0.062 mgd Average Flow: 0.054 mgd (average of maximum monthly values from 2006 through 2010) Receiving Water: Whiskey Creek or New River Sound

Description Florida Atlantic University Sea Tech Facility is a university research institute that engages in various aspects of ocean engineering research activities. Part of the operation carried out at the facility involves the study of marine materials and corrosion effect as relating to offshore structures using natural sea water in holding tanks. Inside the tanks, sea water comes into contact with a variety of coupon-sized test samples of metal (steel and aluminum), reinforced concrete, and carbon fiber composites structural materials that are in suspension and submerged under water. Researches renew the test water in the tanks periodically with new sea water to maintain general freshness and to prevent bio-growth inside the tanks. Florida Atlantic University Sea Tech Facility periodically discharges "spent" test sea water through Outfall D-001 to the south end of the Whiskey Creek or New River Sound. Note that only 5% to 10% of the total sea water withdrawn is actually routed into the two test tanks. The majority of the inflow bypasses the tanks entirely, and flows directly to the outfall. The facility does not treat the spent sea water before discharge due to the historic low level of pollutants being introduced into the waste stream from the test processes, absence of foreign chemical additives used in the study, high proportion of noncontact direct bypass flow, and the very well controlled environment of the laboratory. The test tanks aremanually scrubbed down periodically to remove any larger settled and floating debris or excess biogrowth. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. Potential Incremental Impacts Florida Atlantic University Sea Tech Facility discharges to coastal waters, for which EPA has proposed only chlorophyll-a criterion.

Description The permit for the Harbor Branch Oceanographic Institute at Florida Atlantic University covers a RO water treatment plant that provides drinking water for Harbor Branch Oceanographic Institute at the Florida Atlantic University. Untreated RO concentrate is discharged through Internal Outfall I-002 into a stormwater detention pond which also receives stormwater and onsite well water. Outfall D-001 discharges the combined diluted wastewaters from the stormwater detention pond to the adjacent North Coast Wetlands and ultimately into the Indian River Lagoon. Summary of Effluent Data and Limits Average monthly effluent data for TP from 2006 to 2010 are available from EPA’s ICIS-NPDES database. For TN, a laboratory report indicates that in 2005, TN concentrations were approximately 0.64 mg/L (FDEP, 2006a). There are no effluent limits for TN in the current permit. Exhibit 30 summarizes these data. Exhibit 30: Effluent Data Summary, Harbor Branch Oceanographic Institute at FAU

Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 1.12 mg/L and 0.117 mg/L, respectively, for the Lower Central Indian River Lagoon segment (Segment ID 1505) in the Indian River Lagoon. Although IWR data indicate that the segment is likely in compliance with the proposed criteria, no mixing zone is described in the permit, so it is uncertain as to whether a mixing zone would be granted. EPA conservatively (i.e., erring on the side of estimating greater impact and higher costs under the proposed rule) assumes that the Institute would need to meet effluent limits based on criteria end-of-pipe (i.e., no dilution). Exhibit 31 summarizes the RP analysis and estimated projected effluent limits for the facility.46

Proposed annual geometric mean criterion. 3. Represents criterion end-of-pipe because the existing permit does not provide dilution for effluent limits.

The exhibit indicates that the facility would not likely have RP under the proposed rule for TN because the average effluent concentration is below the proposed criterion, and would not incur incremental compliance costs. However, the facility would likely have RP for TP based on average effluent concentrations. In addition, the facility would not be in compliance with the projected effluent limit for TP and may need to implement some incremental level of control. To meet the projected WQBEL, EPA estimates compliance costs based on installation of chemical precipitation followed by filtration. Capital and O&M unit costs associated with this treatment could be $0.32/gpd and $238/MG, respectively. EPA assumes that treatment would be required only for the RO concentrate stream (Outfall I-002), and not for the other wastewater components (e.g., stormwater and onsite well water). Based on a design flow of 0.014 mgd, total capital costs could be approximately $4,500. During the last 5 years, the average of average monthly flows has been approximately 0.010 mgd. Thus, assuming operation of the treatment units 365 days per year, O&M costs could be approximately $900. Total annual costs would be $1,300 based on annualizing capital costs at 7% over 20 years and adding annual O&M. Exhibit 32 summarizes these costs.

### Marathon Petroleum Company, Port Everglades Eisenhower Boulevard Terminal NPDES permit number: FL0173975 Major/minor: Minor SIC code: 5171 (Petroleum Bulk Stations and Terminals) Industrial Category: Other Design Flow: 0.75 mgd Average Flow: 0.15 mgd (only one maximum monthly value from 2006 through 2010) Receiving Water: Port Everglades Turning Basin

Description Marathon Petroleum Company, Port Everglades Eisenhower Boulevard Terminal is a bulk petroleum products storage and distribution facility consisting of 17 aboveground storage tanks. The 12 major tanks (with capacities ranging from 0.7 to 3.5 MG) store various petroleum products including unleaded gasoline and diesel fuel. A new ethanol storage tank is also under construction. The remaining 5 smaller tanks (with capacities between 21,000 to 340,000 gallons) store fuel additives. There are also two tanks (20,000 gallons each) for storing petroleum contact water and one tank (20,000 gallons) for “Transmix” or pipeline intermixture storage. The tank farm is surrounded by gravel and earthen dikes in an unlined basin. Hydrostatic test water is discharged through Outfalls D-001 to an offsite storm sewer, which ultimately discharges into the Port Everglades Turning Basin. Hydrostatic test water is normally discharged without treatment, although the permit requires analysis prior to discharge to ensure that effluent limitations are met. If necessary, portable water treatment equipment (e.g., diatomaceous earth filters) may be used to reduce the particular pollutant(s) of concern. Oil/water separators treat petroleum contact water, which includes tank bottom water and loading rack runoff. Treated petroleum contact is stored onsite and ultimately hauled offsite for disposal. Recovered oil is stored in the Transmix tank. Stormwater is normally disposed of by percolation and evaporation, however, stormwater discharge is allowed by a separate Multi-Sector Generic Permit. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. Potential Incremental Impacts Marathon Petroleum Company, Port Everglades Eisenhower Boulevard Terminal discharges to coastal waters, for which EPA has proposed only chlorophyll-a criterion. While there are no TN and TP criteria, EPA assumes that Marathon Petroleum Company would be required to meet the concentrations associated with economically feasible treatment (i.e., 3 mg/L for TN and 0.1 mg/L for TP) to reduce the potential for exceeding the chlorophyll-a criterion. However, Marathon Petroleum Company does not have effluent limits or monitoring requirements for TN or TP at the Port Everglades Eisenhower Boulevard Terminal. Given the lack of permit requirements and the nature of the wastewater (i.e., hydrostatic test water), it is unlikely that the facility would have reasonable potential under the proposed rule. Thus, incremental compliance costs are likely zero.48



### Marathon Petroleum Company, Port Everglades Spangler Boulevard Terminal NPDES permit number: FL0000582 Major/minor: Minor SIC code: 5171 (Petroleum Bulk Stations and Terminals) Industrial Category: Other Design Flow: 0.5 mgd Average Flow: Intermittent, 0.48 mgd (average of maximum monthly values from 2006 through 2011) Receiving Water: Port Everglades Turning Basin

Description Marathon Petroleum Company, Port Everglades Spangler Boulevard Terminal is a bulk petroleum storage and distribution facility. This facility has five major storage tanks (2.1 to 5.0 MG capacities) for unleaded gasoline, fuel and fuel additives, and several smaller tanks for storing ethanol (six 30,000 gallon tanks) and petroleum contact water (four 30,000 gallon tanks). The tank farm is surrounded by earthen dikes in an unlined basin, which includes three stormwater detention ponds. Marathon Petroleum Company discharges hydrostatic tank test water from the terminal through Outfall D-001 into a storm sewer that empties into the Port Everglades Turning Basin. Normally, this discharge is not treated, although the permit requires analysis prior to discharge to ensure that effluent limitations are met. Oil/water separators treat petroleum contact water, which includes tank bottom water and loading rack runoff. Treated petroleum contact is stored onsite and ultimately hauled offsite for disposal. Stormwater discharge is covered under a Multi-Sector Generic Permit. Summary of Effluent Data and Limits TN and TP data are not available from EPA’s ICIS-NPDES database. However, a laboratory report indicates that in 2002, TP concentrations were approximately 0.068 mg/L and total Kjeldahl nitrogen concentrations were approximately 0.88 mg/L (FDEP, 2002). TN data are not available for this facility, however total Kjeldahl nitrogen is the sum of organic nitrogen, and ammonia and ammonium as nitrogen, and can be used to estimate TN by adding the concentrations of nitrate and nitrite as nitrogen. Nitrate and nitrite data are not available for this facility, however, laboratory reports from two other Florida NPDES permitted facilities in SIC code 5171: Petroleum Bulk Stations and Terminals report insignificant amounts of nitrate and nitrite. 2 Thus, EPA used total Kjeldahl nitrogen levels as a proxy for TN for this analysis. There are no effluent limits for TN and TP in the current permit. Exhibit 33 summarizes these data.

Potential Incremental Impacts Marathon Petroleum Company, Port Everglades Spangler Boulevard Terminal discharges to coastal waters, for which EPA has proposed only chlorophyll-a criterion. While there are no TN and TP criteria, EPA assumes that the facility would be required to meet the concentrations associated with economically feasible treatment (i.e., 3 mg/L for TN and 0.1 mg/L for TP) to reduce the potential for exceeding the chlorophyll-a criterion. The 2002 discharge report suggests that effluent concentrations likely attain these levels. Therefore, incremental compliance costs are unlikely.50 

### Marine Park of Flagler NPDES permit number: FL0526533 Major/minor: Minor SIC code: 8422 (Arboreta and Botanical or Zoological Gardens) Industrial Category: Other Design Flow: 8.64 mgd Average Flow: 1.89 mgd (average of average monthly values from 2008 through 2011) Receiving Water: Intercostal Waterway

Description Marine Park of Flagler is a 1.3 million gallon human-dolphin interaction habitat for dolphin research and tourism. Ocean water from the Atlantic Ocean is treated by sand filters to remove turbidity and improve clarity. A portion of the incoming ocean water receives additional treatment using ozone for disinfection and fractionators to remove particulate matter and oxidized proteins. The combined water is treated with sodium hypochlorite before entering the dolphin habitat. A portion of the habitat water is treated with lanthanum for algae control and recirculated through the sand filters.

Wastewaters from the habitat and filter backwash water are treated with sodium thiosulfate for dechlorination. The treated wastewaters are discharged to an onsite lagoon, which is connected to the Intracoastal Waterway via outfall pipes. Summary of Effluent Data and Limits

Exhibit 34 summarizes average quarterly effluent data for TN from 2008 to 2011. TP data were not available in EPA’s ICIS-NPDES database or from laboratory reports for this discharger. Exhibit 34: Effluent Data Summary, Marine Park of Flagler

TN 12 0.58 None Source: EPA (2011) 1. TP effluent data from 2008 through 2011. Represents average of maximum monthly values.

Potential Incremental Impacts EPA is proposing annual geometric mean criteria for TN and TP of 0.53 mg/L and 0.108 mg/L, respectively, for the Matanzas River segment (Segment ID 1702) of the Intercostal Waterway in the Guana-Tolomato-Matanzas Estuary. Analysis of FDEP’s IWR data indicate that the segment is not likely in compliance with the proposed TN criterion under the proposed rule but could be in compliance with the proposed TP criterion. However, because the existing permit does not describe a mixing zone for calculation of other pollutant limits, EPA conservatively (i.e., erring on the side of estimating greater impact and higher costs under the proposed rule) assumes the discharger would not receive a mixing zone under the proposed rule. Exhibit 35 summarizes the RP analysis and estimated projected effluent limits for the facility.51

Proposed annual geometric mean criterion. 3. Represents criterion end-of-pipe even though ambient data indicate that the segment may be in compliance with the proposed criteria because the existing permit does not provide dilution for effluent limits.

The exhibit indicates that the facility would likely have RP under the proposed rule for TN because the average effluent concentration exceeds the proposed criterion. Based on average effluent concentrations, the facility would not be in compliance with the projected effluent limit for TN and may need to implement some incremental level of control. However, due to the extremely low TN criterion, there is significant uncertainty as to whether the projected effluent limits are technologically or economically feasible to attain. Thus, EPA estimates costs based on the assumption of a variance from meeting effluent limits based on criteria end-of-pipe. Since current effluent TN levels are already below the concentration associated with economically feasible nitrogen treatment (i.e., 3 mg/L for TN), incremental compliance costs associated with TN are also unlikely. For TP, there are no effluent data from which to assess compliance, and the Marine Park of Flagler does not have existing effluent limits or monitoring requirements for TP. Given the lack of existing permit requirements, existing treatment, and the nature of the wastewater (e.g., treated ocean water), it is unlikely that the Park would have reasonable potential under the proposed rule. Thus, incremental compliance costs are likely zero.52 

### Motiva Enterprises LLC, Port Everglades East Terminal NPDES permit number: FL0035351 Major/minor: Minor SIC code: 5171 (Petroleum Bulk Stations and Terminals) Industrial Category: Other Design Flow: 0.5 mgd Average Flow: No discharges in the past five years Receiving Water: Intracoastal Waterway

Description Motiva Enterprises LLC, Port Everglades East Terminal is a bulk petroleum storage and distribution facility consisting of 15 main aboveground tanks (with capacities of 0.44 to 3.3 MG) storing aviation gasoline, jet fuel, and diesel. In addition, the facility has two smaller tanks (10,000 and 20,000 gallons) for storing petroleum contact waters. The 15-acre site includes five acres of impervious area (office building and truck loading rack operation) and 10 acres of unlined pervious basin areas that comprise three secondary containment cells. Hydrostatic tank test water and stormwater from the facility are discharged through Outfall D-001 to the Florida Power and Light cooling water discharge canal (which also receives effluent from Florida Power and Light, Lauderdale Plant, FL0001538, and other NPDES permitted dischargers), which ultimately discharges into the Intracoastal Waterway. Hydrostatic test water is normally discharged without treatment, although the permit requires analysis prior to discharge to ensure that effluent limitations are met. Stormwater runoff from outside of the roofed loading rack perimeter the impervious area is pumped to the pervious diked area. Disposal of runoff and stormwater collected within the diked area is normally by percolation and evaporation, any excess stormwater drained across the three secondary containment cells and eventually to the outfall. Oil/water separators treat petroleum contact water, which includes runoff from within the loading rack perimeter and tank bottom water. Treated petroleum contact is stored onsite and ultimately hauled offsite for disposal. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. Potential Incremental Impacts Motiva Enterprises LLC, Port Everglades East Terminal discharges to coastal waters, for which EPA has proposed only chlorophyll-a criterion. While there are no TN and TP criteria, EPA assumes that Motiva Enterprises LLC would be required to meet the concentrations associated with economically feasibletreatment (i.e., 3 mg/L for TN and 0.1 mg/L for TP) to reduce the potential for exceeding the chlorophylla criterion. However, Motiva Enterprises LLC does not have effluent limits or monitoring requirements for TN or TP at the Port Everglades East Terminal. Given the lack of permit requirements, the nature of the wastewater (i.e., hydrostatic test water and stormwater) and that no discharges have occurred in the past five years, it is unlikely that the terminal would have reasonable potential under the proposed rule. Thus, incremental compliance costs are likely zero.53 

### Motiva Enterprises LLC, Port Everglades South Terminal NPDES permit number: FL0167720 Major/minor: Minor SIC code: 5171 (Petroleum Bulk Stations and Terminals) Industrial Category: Other Design Flow: 0.5 mgd Average Flow: 0.41 mgd (only one maximum monthly value from 2006 through 2010) Receiving Water: Intracoastal Waterway

Description Motiva Enterprises LLC, Port Everglades South Terminal is a bulk petroleum storage and distribution facility consisting of 9 aboveground tanks (with capacities of 1.80 to 4.06 MG) storing unleaded gasoline, super unleaded gasoline, aviation jet fuel, diesel and ethanol, and two smaller tanks (30,000 gallon) for storing petroleum contact water, and a tank for storing chemical additives (30,000 gallon). The tank farm is surrounded by earthen dikes in an unlined basin. Hydrostatic tank test water and stormwater are discharged through Outfall D-001 to an unnamed drainage ditch. From the unnamed drainage ditch, the discharge proceeds to the Eller Drive ditch, and then to the Florida Power and Light cooling water discharge canal (which also receives effluent from Florida Power and Light, Lauderdale Plant, FL0001538, and other NPDES permitted dischargers), which ultimately discharges into the Intracoastal Waterway. Hydrostatic test water is normally discharged without treatment, although the permit requires analysis prior to discharge to ensure that effluent limitations are met. Disposal of stormwater is normally by percolation and evaporation. However, stormwater may be discharged through Outfall D-001 if no oil sheen is present. Oil/water separators treat petroleum contact water, which includes tank bottom water and loading rack runoff. Treated petroleum contact is stored onsite and ultimately hauled offsite for disposal. Summary of Effluent Data and Limits There are no effluent TN and TP data available in EPA’s ICIS-NPDES database for this discharger. Potential Incremental Impacts Motiva Enterprises LLC, Port Everglades South Terminal discharges to coastal waters, for which EPA has proposed only chlorophyll-a criterion. While there are no TN and TP criteria, EPA assumes that Motiva Enterprises LLC would be required to meet the concentrations associated with economically feasible treatment (i.e., 3 mg/L for TN and 0.1 mg/L for TP) to reduce the potential for exceeding the chlorophyll-a criterion. However, the Motiva Enterprises LLC does not have effluent limits or monitoring requirements for TN or TP from the Port Everglades South Terminal. Given the lack of permit requirements and the nature of the wastewater (i.e., hydrostatic test water and stormwater), it is unlikely that the facility would have reasonable potential under the proposed rule.

## Appendix: Alternative Treatment Scenario

EPA projected extremely low WQBELs for five dischargers that may not be feasible to attain. Thus, EPA estimated costs based on a scenario in which the dischargers pursue a variance from WQS. Actual revised WQBELs may differ from those estimated by EPA, and dischargers may pursue alternative compliance methods. Exhibit 36 provides the estimated costs of a scenario in which the dischargers install RO to meet revised effluent limits, based on the unit costs presented in the economic analysis accompanying the proposed rule [capital costs and O&M costs for RO with microfiltration of $8.10/gpd and $3,000/MG, respectively, including residual disposal via a brine concentrator, based on Carollo Engineers (2009)].
