1. Describe the wastewater-generating processes.

Outfall 001 - Main Cooling Reservoir Outfall 001 is the discharge point for the 7,000-acre main cooling reservoir. This reservoir is part of the main recirculating cooling water loop used to remove heat from the steam-electric generating units. There has not been a discharge from Outfall 001 since March 1997 other than minor permitted leakage through the closed spillway gates and relief wells. If a discharge were to occur, blowdown from the main cooling reservoir would make up the largest percentage of wastewater. A discharge from Outfall 001 would flow to the Colorado River (Colorado River Tidal in Segment 1401 of the Colorado River Basin).

All internal outfalls (Outfalls 101, 201, 401, and 601) discharge to the main cooling reservoir.

Outfall 501 would also discharge to the reservoir via Outfall 101, but has not discharged since 1992.

Outfalls 101and201-Low Volume Wastewater Low volume wastewater results from water treatment operations, boiler blowdown, HVAC blowdown, floor drains, SPCC sources and their associated oily water treatment system discharges, and other miscellaneous sources. Boiler blowdown is from one auxiliary steam boiler, released to reduce impurities in the water that can cause corrosion and boiler tube failure.

Service water is demineralized and regeneration of the demineralizer resin beds produces an acidic and caustic wastewater that is treated at the neutralization basins along with boiler blowdown. The floor drain system captures condensate and water from production and maintenance areas that may contain oil or grease, which is then transported to the oily waste treatment system where the oil is separated from the water. The first flush of stormwater from some production and storage areas is also treated in the oily waste system. Other non-process stormwater flow is directed through designated storm water outfalls.

Outfalls 401 and 601 - Treated Domestic Wastewater Domestic wastewater is treated onsite in two package treatment systems consisting of aeration, clarification, and disinfection. Car wash water, air conditioning condensate, HVAC cooling tower blowdown, and stormwater are commingled with the domestic wastewater prior to treatment.

Outfall 501-Metal Cleaning Waste Metal cleaning waste has not been discharged since 1992. Metal cleaning using chemical or nonchemical liquids produces a waste that would be discharged through Outfall 501 to the neutralization basins (Outfall 101). Stormwater may also be discharge through Outfall 501.

Outfalls 002 through 006 - Main Cooling Reservoir (MCR) Relief Well Effluent MCR relief well effluent is collected from the perimeter of the MCR and discharged via Outfalls 002 through 006 without treatment. Outfall 002 is also authorized to discharge demineralized water from instrumentation.

b. Provide the following information as an attachment.

1. A narrative description of the design and annual operation of the facility's cooling water system and its relationship to the CWIS(s).

South Texas Project Electric Generating Station (STPEGS) is a nuclear-powered steam electric plant with two generating units (Units 1 and 2) operating as a member of the Electric Reliability Council of Texas (ERCOT) supplying power to the grid. For cooling purposes, STPEGS employs a closed-cycle recirculating cooling system utilizing a 7,000-acre main cooling reservoir (MCR) as an impoundment for the closed-cycle recirculating system. Under current operating conditions, new water to the MCR is provided by rainfall and periodic make-up water diverted from the Colorado River.

The cooling water intake structure located on the Colorado River is referred to as the Reservoir Makeup Pumping Facility (RMPF). The RMPF Cooling Water Intake Structure operates as a make-up water intake providing make-up water from the Colorado River, a water of the U.S., to the MCR, which is not a water of the U.S. The RMPF Cooling Water Intake Structure is operated intermittently based on reservoir level and river flow. Conditions of river water diversions are limited to 55% of the river flow and only when river flow exceeds 300 cubic feet per second (cfs). While the design intake flow (DIF) (387.792 million gallons per day [MGD]) could result in the removal of 22.6% of the mean annual river flow (2,648 cfs-1,711 MGD), the actual river flow withdrawal over the past 3 years (2016-2018) occurring from intermittent diversion to the MCR was limited to 2.05%. From the reported 5-year period (2014-2018), STPEGS' annual average capacity factor was 91.4 % for Unit 1, 98. 9% for Unit 2 with a combined 95.2 % station utilization.

Make-up water usage from the Colorado RivPr Pquates to a mean of 35 MGD.

2. A scaled map depicting the location of each CWIS, impoundment, intake pipe, and canals, pipes, or waterways used to convey cooling water to, or within, the cooling water system. Provide the latitude and longitude for each CWIS and any intake pipe(s) on the map. Indicate the position of the intake pipe within the *water column.

Figure 1 shows the location of the RMPF Cooling Water Intake Structure on the Colorado River, the make-up water pipeline from the RMPF Cooling Water Intake Structure to the Main Cooling Reservoir, the Reservoir Circulating Water Intake Structure in the Main Cooling Reservoir, and the Essential Cooling Pond. Additional details are provided in the engineering drawings in Appendix 1.

3. A description of water reuse activities, if applicable.

Water discharges from internal outfalls 101, 201, 401, and 601 are discharged into the Main Cooling Reservoir for reuse in accordance with the wastewater permit.

4. Design and engineering calculations prepared by a qualified professional and data to support the information provided in above item a.

The RMPF Cooling Water Intake Structure supports a DIF of 387.792 MGD based on four, single speed, line-drive turbine pumps operating with a pump rate of 26,930 gallons per minute (gpm) per each of two small-volume pumps and a pump rate of 107,720 gpm per each of two large-volume pumps over a 24-hour period. The following provides the calculation for estimating the DIF: 26,930 + 107,720 X 2 pumps X 60 min X 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />s/ 1,000,000 = DIF.

Based upon the facility's reported diversion from the Colorado River for 3 years, 2016-2018, the annual volume from all four pumps was 14,719.3 + 18,217.8 + 5,024.9 million gallons per year respectively. The daily actual intake flow (AIF) computed on 365 days/year for each year 2 P: \Projects\ 0494757\ DM\27552H(AttM).docx

Attachment M Worksheet 11.0, page 73 equates to 40.32 + 49.91 + 13.77 MGD with a three-year average of 34.67 MGD. This equates to 8.9% (34.67 + 387.792) of the DIF volume or a 91.1 % reduction in actual usage from the DIF.

6. A narrative description of existing or proposed impingement and entrainment technologies or operation measures and a summary of their performance, including, but not limited to, reductions in impingement mortality and entrainment due to intake location and reductions in total water withdrawals and usage.

STPEGS utilizes a closed-cycle recirculating system for achieving impingement reduction as stated under 40 CFR § 125.94(c)(l). This closed-cycle recirculating system is comprised of a 7,000-acre cooling impoundment. The point of compliance for 316(b) will be the RMPF Cooling Water Intake Structure located on the Colorado River.

STPEGS has an AIF of 34.7 MGD, which is less than 125 MGD required for meeting the site-specific entrainment (E) requirements. While there is no prescribed single nationally-applicable E-standard, the Rule requires the Director to establish best technology available (BTA) on a site-specific basis. South Texas Project Nuclear Operating Company (STPNOC) believes the BTA technologies identified in this document not only support the impingement mortality (IM) BTA evaluation, but also support the evaluation of BTA for E.

Furthermore, it is STPNOC' s position that STPEGS' s closed-cycle cooling BTA for IM serves as BTA for entrainment under §125.94(d), should the TCEQ decide to evaluate STPEGS's CWIS under the rules for entrainment standards.

In addition to the pre-approved technology of a closed-cycle recirculating system for IM BTA STPEGS utilizes a combination of other technologies that effectively reduce the likelihood of fish impingement and entrainment including:

1) Large capacity cooling water impoundment (MCR) designed for industrial cooling water and waste water. The size of the MCR provides for reduced water diversions i.e.

make-up water from waters of the US;

2) Traveling screens fitted with 3/8 mesh and fish return designed to return fish at the RMPF Cooling Water Intake Structure downstream of the intake; and

3) Credit for intake location in channel border habitat outside of the bio-productive areas within the source water.

b. Provide the following information as an attachment.

1. A narrative description of the configuration of each CWIS, annual and daily operation, including any seasonal changes, and where it is located in the water body and in the water column.

The South Texas Project Electric Generating Station (STPEGS) Reservoir Makeup Pumping Facility (RMPF) Cooling Water Intake Structure is located on the right descending (west) bank of the Colorado River near river mile 14.6 (28°46'27.97'N, 95°59'51.84"W). The RMPF Cooling Water Intake Structure withdraws water through a 406-foot long intake along the shoreline of the Colorado River. Water from the river flows through trash racks with 4-inch bar spacing, then through traveling screens, and over a weir into an embayment before entering the pumps and subsequently into a pipeline delivering makeup water to the 7,000-acre main cooling reservoir (MCR), an impoundment of this closed cycle recirculating system.

At the RMPF Cooling Water Intake Structure, 12 vertical traveling screens exist, each with 3/s-inch mesh and a 13.5-foot width. The bottom of the screens are positioned 10 feet below mean sea level (MSL) in the Colorado River based on a water surface elevation of 0 feet MSL. When operating, screen rotation and wash are initiated by differential pressure or optionally can be operated manually dependent upon debris loading. Fish swimming through the trash racks can move laterally along the face of the intake structure and exit through the trash racks. Fish and debris impinged on the intake screens would be washed (via screen wash) into a sluice and fish bypass and returned back to the Colorado River downstream of the intake.

New water to the MCR is provided by direct rainfall, as it is a perched reservoir receiving no runoff, and make-up water diverted periodically from the Colorado River. The pumps are operated intermittently based on reservoir level, river flow and the operability of the reservoir pumping facility. Conditions of river water diversions are limited to 55% of the river flow and only when river flow exceeds 300 cubic feet per second (cfs). While the design intake flow (DIF) (387.792 million gallons per day [MGD]) could result in the removal of 22.6% of the mean annual river flow (2,648 cfs-1,711 MGD), the actual river flow withdrawal over the past 3 years occurring from intermittent diversion to the MCR is limited to 2.05%. Please see Attachments Mand P for operational use and status.

2. Engineering calculations for each CVVIS.

The RMPF Cooling Water Intake Structure consists of four makeup pumps. Pumps 1 & 2 are small volume capacity (26,930 gallons per minute [gpm] each) and Pumps 3 & 4 are large volume capacity (107,720 gpm each). The four pumps have a combined design intake flow (DIF) of 387.792 MGD. The following provides the calculation for estimating the DIF:

26,930 + 107,720 X 2 pumps X 60 min X 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />s/ 1,000,000 = DIF. The two smaller pumps each exist with a 36-inch discharge and the two larger pumps each have a 66-inch discharge. All four pumps discharge into a common header subsequently providing makeup water to the MCR through a 1-mile long, 108-inch pipeline.

b. Provide the following information as an attachment.

1. A narrative description of the source water for each CWIS, including areal dimensions, depths, salinity and temperature regimes, and other documentation that supports your determination of the water body type where each cooling water intake structure is located.

South Texas Project Electrical Generating Station (STPEGS) withdraws water from the Colorado River for cooling water purposes via the Reservoir Makeup Pumping Facility (RMPF) Cooling Water Intake Structure. The RMPF Cooling Water Intake Structure is located on the west bank of the lower Colorado River approximately 13 miles southwest of Bay City, Texas and 10 miles north of Matagorda Bay (Figure 1). Water from the Colorado River, a water of the U.S., provides makeup water for cooling water losses to the main cooling reservoir (MCR), not a water of the U.S.

The RMPF Cooling Water Intake Structure is located parallel to the shoreline of the Colorado River. Water enters the RMPF Cooling Water Intake Structure through a coarse trash rack and traveling mesh screens into a siltation basin before entering the pumping station. The water is pumped from the siltation basin to the MCR through one buried 108-inch diameter pipeline.

The nearest station (08162501) is located in the vicinity of the RMPF Cooling Water Intake Structure location. Data from this station were available from February 2012 through October 2018. Water temperature data collected from 2012 to 2018 show the temperature ranges from 12° C to 32.1° C, with highest temperatures between the months of May and September and lowest temperatures in December (Figure 3). Data collected by ENSR (2008)2 during trawl sampling ranged from 12.3° C to 31.0° C. A similar trend was observed with highest temperatures between June and September and lowest temperatures in January (Figure 4) .

Specific conductance data from USGS 08162500 in the Colorado River were used to assess conditions at the RMPF Cooling Water Intake Structure location. Data collected from 2012 through 2018 were converted to salinity (practical salinity units [psu]).

Salinity ranged from 0.1 to 7.1 psu (Figure 5). Data collected by ENSR (2008) during trawl sampling ranged from 0.2 to 8.2 psu at the surface and 0.2 to 23.0 psu at the bottom (Figure 6).

2. A narrative description of the source waterbody' s hydrological and geomorphological features.

The Colorado River originates south of Lubbock and flows generally southeast for 862 miles before emptying into the Gulf of Mexico at Matagorda Bay. Major tributaries include Concho River, Pecan Bayou, Llano River, San Saba River, and Pedernales River.

The Colorado River Basin is approximately 42,318 square miles and includes almost 15%

of Texas. The watershed includes several major metropolitan areas, including Midland-Odessa, San Angelo, and Austin, as well as hundreds of smaller towns and communities. The section of the river where STPEGS is located is a slow-moving, scenic river that is wide and deep.3,4 The Colorado River contains several man-made reservoirs including Lake Buchanan, Inks Lake, Lake Lyndon B. Johnson, Lake Marble Falls, Lake Travis, Lake Austin, and Lady Bird Lake, collectively referred to as the Highland Lakes. Three reservoirs located upstream of the Highland Lakes, Lake J.B. Thomas, E.V. Spence Reservoir, and O.H. Ivie Reservoir are owned and operated by the Colorado River Municipal Water District. The Upper Colorado River Authority and the Lower Colorado River Authority manage flood control and use of the Colorado River.s The RMPF Cooling Water Intake Structure is located in the Floodplains and Low Terraces of the Western Gulf Coastal Plain ecoregion. This region consists of bottomland forests of pecan, water oak, southern live oak and elm, with some bald cypress on larger streams. Land cover is a mix of forest, cropland, and pasture.

The RMPF Cooling Water Intake Structure is located within Segment 1401- Colorado River Tidal of the Colorado River Basin, which extends from the confluence with the Gulf of Mexio in Matagorda County to a point 1.3 miles downstream of the Missouri-Pacific Railroad in Matagorda County. The reservoir has been designated for the following uses by the TCEQ: primary contact recreation, high aquatic life use, and general use. The numeric water quality criteria specified for the river segment include a minimum 24-hour mean dissolved oxygen at any point of 4.0 mg/L, a pH range of 6.5 to 9.0 units, an indicator bacteria count of 35 colonies per 100 milliliters (mL), and a maximum temperature of 95 °F (35 °C).6 The RMPF Cooling Water Intake Structure is located on the west bank of the Colorado River approximately 14.6 miles upstream from Matagorda Bay. Water enters the intake structure via a 406-foot long intake structure located parallel to the shoreline in channel 3

Using data (1948-2008) from uses 08162500 on the Colorado River near Bay City, Texas, the Colorado River has a mean annual flow of approximately 2,648 cubic feet per second (cfs) which equates to approximately 1,711 million gallons per day (MeD) of flow (Figure 7). Based on these data, it is estimated that the facility withdraws a maximum 22.6 % of the mean river flow when pumping at maximum capacity. The actual withdrawal over the past 3 years was calculated to be 2.05 %.

The zone of influence (ZOI) associated with the RMPF Cooling Water Intake Structure at the STPEGS was calculated based upon client-provided design drawings and information related to structure and system data (Attachments M and N) and source vvater phJ'Sical data (l\ttachrrlerLt 0). Periodicall;r, four river-,*vater intake pumps withdraw make-up water from the Colorado River at the RMPF Cooling Water Intake Structure through eighteen 13.5 feet wide by 10-feet deep intake bays located along the shoreline. The RMPF Cooling Water Intake Structure includes two small-volume capacity pumps each with a pump rate of 26,930 gallons per minute or 60 cubic feet per second (ft3/s) and two large-volume capacity pumps each with a pump rate of 107,720 gpm or 240 ft3/s. Combined, all four pumps discharge at a rate of 269,300 gpm or 600 ft3/ s. The maximum velocity through each screen bay is 0.96 feet per second (ft/ s). The ZOI consist of a semi-circle area calculated for each screen bay with a radius of 11.05 feet with an overlap to each other representing their combined influence. Table 1 and Figure 9 include the ZOI data and expected effect.

Attachment Q Worksheet 11.1, page 77 iii. A narrative description of any physical or operational measures taken to minimize make-up withdraws.

The Reservoir Makeup Pumping Facility (RMPF) Cooling Water Intake Structure pumps are operated intermittently based on reservoir level, river flow and the operability of the reservoir pumps. Conditions ofriver water diversions are limited to 55% of the river flow and only when river flow exceeds 300 cubic feet per second (cfs). While the design intake flow (DIF) (387.79 MGD) could result in the removal of22.6% of the mean annual river flow (2,648 cfs-1,711 MGD), the actual river flow withdrawal over the past 3 years (2016-2018) occurring from intermittent diversion to the MCR was limited to 2.05%. From the reported 5-year period (2014-2018), STPEGS' annual average capacity factor was 91.4% for Unit 1, 98.9% for Unit 2 with a combined 95.2% station utilization. Make-up water usage from the Colorado River equates to a mean of 35 MGD.

Water discharges from internal outfalls 101, 201, 401, and 601 are discharged into the Main Cooling Reservoir for reuse in accordance with the wastewater permit.

b. Provide the following information as an attachment.

a. A list of the data requested at 40 CFR § 122.21(r)(4)(ii) through (vi) that are not available and efforts made to identify sources of the data.

An extensive dataset has been compiled by South Texas Project Nuclear Operating Company (STPNOC) in an effort to support STPNOC' s 316(b) compliance, including historical biological demonstrations and studies specific to the South Texas Project Electric Generating Station (STPEGS), including impingement and entrainment studies associated with the Reservoir Make-up Pumping Facility (RMPF) Cooling Water Intake Structure and studies characterizing the biota of the lower Colorado River near the RMPF Cooling Water Intake Structure. Data taken from source waters over the course of 30 years indicate no adverse environmental impacts on the lower Colorado River fishery. STPNOC believes the combination of the historical studies and more recent data support the requirements under 122.21 (r)(4)(ii) through (vi) and will demonstrate STPEGS currently operates BTA that meets the standards for IM and E under 40 CFR § 125.94(c) and (d). A summary of the sampling studies utilized is provided below.

U.S. Nuclear Regulatory Commission (NRC) 1975. Final Environmental Statement:

Construction Phase - STP Units 1 and 2 Data were collected from 1973-1974. Seventeen species were identified during the study with bay anchovy (35.6 %) and Gulf menhaden (20.0%) the dominant species collected.

McAden et al. 1984 and 1985. Colorado River Entrainment and Impingement Monitoring Program, Reports 1 and 2 Data were collected from July 1983-June 1984 and July-December 1984 during reservoir fill pumping at the RMPF Cooling Water Intake Structure, according to section 6.1.3.2 and Appendix E of the FEIS for the STPEGS. This study was completed in order to verify operational impacts associated with impingement and entrainment. Overall, nektonic species richness in samples taken from the lower Colorado River ranged from 24 to 26 during this sampling period, depending upon sampling date and sampling method used (seine vs trawl).

Zooplankton and ichthyoplankton richness was recorded as 59 species in 1983-1984, and 36 species in 1984; plankton net samples in both sampling periods are intended to represent the community of entrainable organisms in the lower Colorado River near the RMPF Cooling Water Intake Structure. Nine species were noted as impinged in the July 1983-June 1984 data, while four species were impinged in the July-December 1984 data.

NRC 1986. Final Environmental Statement - STP Units 1 and 2 This document compared data and conclusions from the Construction Phase Final Environmental Statement (FES-CP; NRC 1975) with the more recent studies conducted by McAden et al. in 1983 and 1984. NRC concluded entrainment impacts to the fauna! community of the lower Colorado River will not be significant due to low numbers, the fact that lower Colorado River does not appear to be unique among estuarine-marine nurseries, ubiquity of entrained species of commercial importance, and pumping will occur during high river flow (freshwater influence) thereby reducing the impact to estuarine-marine species. Likewise, NRC concluded impingement would result in only minor effects on the lower Colorado River biota, based on low total density, screen position, lack of unique nursery environment, and ubiquity of impinged species of commercial importance.

Attachment R Worksheet 11.2, page 80 ENSR 2008. Aquatic Ecology - Colorado River Monitoring Report: Unit 3 and 4 Licensing ENSR conducted a year-long field study to determine the fish and macroinvertebrate community composition in the lower Colorado river associated with STPEGS facilities, compare with historical data to determine impacts of STPEGS Units 1 and 2, and document salinity patterns in the lower Colorado River. This study included 186 samples over a year-long assessment using trawls, seines, gill nets, and hoop nets in the lower Colorado River. A total of 69 species (11 invertebrates and 58 fish species) were identified from this sampling effort. There was considerable seasonal variation in species composition within each sampling gear used, with white shrimp and a common dominant species in the fall for both trawl and seine methods. Spring and summer composition varied among methods, with trawls being dominated by bay anchovy, brown shrimp, atlantic croaker and sand trout in spring, and spring seines yielded mostly Gulf menhaden, striped mullet, and grass shrimp. Summer trawls were dominated by blue catfish, white shrimp, and Gulf menhaden, while summer seine samples were dominated by inland silverside, gizzard shad, and striped mullet. Comparison with communities represented in the 1973-74, 1975-76, and 1983-84 data indicated that overall, the faunal community observed in 2008 was more diverse than that represented by historic data in the lower Colorado River.

NRC 2011. EIS for Combined Licenses - STP Units 3 and 4 NRC examined each of the historic studies listed above, and determined that the results and conclusions of the earlier impingement and entrainment studies were still applicable due to design features of the RMPF Cooling Water Intake Structure that would minimize losses of organisms. These design features would not change due to the addition of Units 3 and 4. NRC concluded that due to use of the MCR as closed-cycle cooling, infrequent pumping of water at low velocity, and the presence of trash racks, traveling screens, and fish return system, the impacts from impingement and entrainment for the proposed units would be minor. Units 3 and 4 were terminated prior to completing construction.

NRC 2013. EIS for License Renewal - STP Units 1 and 2 NRC examined each of the historic studies listed above, and concluded that the impacts due to entrainment and impingement by the STPEGS cooling water system on aquatic resources to be small. This is due to design features of the RMPF Cooling Water Intake Structure that minimize losses of organisms, as well as the conclusions of previous studies indicating minimal impact and the continued presence of those aquatic species most likely to be impinged in the lower Colorado River.

b. Provide a list of species (or relevant taxa) in the vicinity of the CWIS and identify the following information regarding each species listed.

An examination of bag seine and trawl data from the lower Colorado River in 1974, 1983-84, and 2007-08, as well as gill net and hoop net data from 2007-08 indicates that a total of 90 species were collected among all three studies. In the 2008 study, 72 species were collected with 33 of these species representing 99% of the total catch. In 1983-84, 48 species were collected with 20 species representing 99% of the total catch. In 1974, 27 species were collected with 17 species representing 99% of the total catch. While there was variation among studies, there were nine species in the top 99% of all three studies.

1. all life stages and their relative abundance, Historical Impingement Data Data from the entrainment and impingement studies in 1983 and 1984 described 10 species impinged at the RMPF Cooling Water Intake Structure during phase II sampling of the intake screens. Four of these species were numerically dominant in the impingement samples and contributed >1 % of the total organisms impinged, including blue crab, river shrimp, white shrimp, and ghost shrimp. All of these species are considered estuarine species. A single freshwater species, the green sunfish (Lepomis cyanellus) was also impinged but was not included in the study summary due to the fact that it is a freshwater fish and therefore not a part of the estuarine community assessed in this study (Figure 4).

Mississippi Grass Shrimp 0.91%

FIGURE4: Percent Composition of all Species Impinged at the RMPF Cooling Water Intake Structure during Sampling in 1983 and 1984 The ENSR 2006 IMECS report examined impingement data from other Texas estuarine facilities and found eight species comprised the majority of impingement among the facilities including Gulf menhaden, Atlantic croaker, white shrimp, brown shrimp, blue crab, bay anchovy, sand seatrout, and striped mullet (Table 2). The total number of species impinged was lower at the RMPF Cooling Water Intake Structure than in other studies. However, the blue crab, white shrimp, and Palaemonid shrimp (grass shrimp, Mississippi grass shrimp, ghost shrimp, and pink shrimp), which are all commonly impinged at other Texas estuarine facilities, cumulatively comprised >75% of the individuals impinged at the RMPF Cooling Water Intake Structure in 1983 and 1984. When coupled with the relatively small sample size from STPEGS in 1983 and 1984, this overlap in dominant species indicates a similarity in impinged species between this and similar intake structures located in estuarine systems in Texas.

3 Striped mullet was selected over Atlantic Cutfassfish as a dominant species due to its relatively frequent occurance in TPWD bag seine data.

Historical Entrainment Data Samples were taken using 0.5m plankton nets in the lower Colorado River in 1983 and 1984 in order to represent the faunal community present in the vicinity of the RMPF Cooling Water Intake Structure susceptible to entrainment. A total of 59 taxa (49 invertebrates and 10 vertebrates) were collected in June -

September 1983 samples, dominated by cladocerans (water fleas), copepods, and Malacostraca such as mysid shrimp, amphipods, commercial shrimp, grass and river shrimp, and crabs. Of the 10 fish taxa collected, only the bay anchovy occasionally occurred in large numbers. In 1984, the most abundant invertebrate plankton were jellyfish medusa, copepods, barnacle nauplii, and zoeal larvae of Malacostraca, specifically grass shrimp, mud shrimp, ai--id xanthid mud crabs (Figure 5).

Of these 90 taxa, only 20 species represent greater than 1 % of the total abundance for any of the historic studies in the lower Colorado River (Table 1). Dominant species included Gulf menhaden, white shrimp, river shrimp, grass shrimp, and bay anchovy (Figures 6 - 8). Several of these species are similar to those identified in the historical impingement sampling at the RMPF Cooling Water Intake Structure.

2. identification of all species and life stages that would be most susceptible to impingement and entrainment, Susceptibility to impingement and entrainment is dependent upon a variety of interrelated factors including size, life stage, swimming speed, intake flow velocity, rheotaxis, seasonal variation, habitat preference, etc. Studies have shown that smaller, juvenile individuals are more susceptible to impingement than their larger, adult counterparts.1,2 Young fish often exhibit higher natural mortality or weakened swimming ability due to stresses including extreme water temperature, low dissolved oxygen, strong flow velocity, physical damage, and infectious disease. 2 The relative abundance data provided by STPNOC, ENSR, and NUREG were compared with the previous impingement and entrainment studies and species life history information to evaluate and determine those species or families most susceptible to impingement and entrainment impacts at the RMPF Cooling Water Intake Structure. To develop a list of species susceptible to impingement, species that occurred in high abundances within the historic studies of the lower Colorado River that are also known to exhibit slow swimming speeds were added to the list of species impinged from the historical studies. To develop a list of species susceptible to entrainment, life history information for the fish species identified in the historic data were assessed to determine spawning habitat preference, spawning periods, and spawning frequency.

Applicable species were added to the list of species entrained from the historical studies. Table 4 provides a summary of the 16 species identified as being susceptible to impingement, and Table 5 provides a summary of the species identified as being susceptible to entrainment at the RMPF Cooling Water Intake Structure.

3. forage base, Estuarine systems are highly diverse systems. Biological data for the lower Colorado River indicated the species present are interchangeable between estuarine and freshwater species with the estuarine species being dominant most of the time. Forage species include: Gulf menhaden, mullet, shrimp, blue crab, silversides, anchovy, and other shad species.

4. significance to commercial fisheries, Several of the fish and shellfish species occurring in the lower Colorado River are considered commercially or recreationally important (CRI) species. These species include fish that are targeted by commercial fisheries, recreational anglers, or serve as the forage base for the targeted species. A list of CRI species in the lower Colorado River is provided in Table 6 below.

5. significance to recreational fisheries, See Section b.1.4. and Table 6 above.

6. primary period of reproduction, Spawning and recruitment (movement into the bays as juveniles) of estuarine species is widely variable and dependent upon regional location, habitat conditions, and environmental conditions. It is expected that most, if not all, of the species identified as being susceptible to impingement do not spawn in the lower Colorado River. Spawning will occur in the nearshore Gulf near the river mouths and passes.

Spawning may be influenced by environmental variables including water temperature, freshwater inflow, turbidity, and photoperiod. Spatiotemporally, spawning is highly dependent on the species in terms of their environmental preferences, reproductive strategy and the environmental conditions during spawning. However, based on data presented from the RMPF Cooling Water Intake Structure entrainment studies and species-specific spawning information it can be assumed that peak spawning will occur in spring followed by late spawning into the early sumrners months of June and July. The species-specific spawning periods and recruitment periods of the species identified as susceptible to impingement and entrainment are detailed below in Table 7.

7. la1P7val ;ecriA-itmcntf and Once spawning occurs eggs and larvae will float in the water column and then will be transported by currents into the shallow bay waters or rivers that act as nurseries. The time frame for ontogenetic process (eggs to larvae to juvenile) will vary by species. Current literature indicates that once eggs are released it can take between 10 to 60 days for most species to become larvae and then more than 30 days to move from larvae to post-larvae or actual juvenile stage. This temporal lag between eggs to larvae and then larvae to juvenile indicates that the spawning to recruitment process for most of these species represented in lower Colorado River would more than likely be late larvae or early juveniles before reaching the STPEGS RMPF Cooling Water Intake Structure.

Following the abundance of adults during spawning season, a temporal lag of roughly one to two months will occur in which there will be a peak in the abundance of larval stages associated with recruitment into the river. Entrainment data from NUREG recorded in 1983-1984 indicated that larval densities were lower in the first sampling period (early July) than in the other sampling periods (late July, early August, and mid-September).

d. Identify all threatened, endangered, and other protected species that might be susceptible to impingement and entrainment at your cooling water intake structures.

Review of United States Fish and Wildlife Service (USFWS) Threatened and Endangered Species List on March 10, 2019 for Matagorda County identified ten protected species: one mammal, four bird, and five reptile species as shown in Table 8. None of these species are considered susceptible to impingement and entrainment at the STPEGS RMPF Cooling Water Intake Structure. No critical habitat was identified in the vicinity of the RMPF Cooling Water Intake Structure.

e. Documentation of any public participation or consultation with federal or state agencies undertaken and provide an attachment number.

STPNOC met with TCEQ in July 2017 to discuss compliance for STPEGS.

The following is required for existing facilities only. Include the following information with the above listed attachment.

f Identify any protective measures and stabilization activities that have been implemented, and provide a description of how these measures and activities affected the baseline water condition in the vicinity of the intake.

The RMPF Cooling Water Intake Structure is designed with steel sheet piling around the structure to provide protective measures and shoreline stabilization. Additionally, STPNOC frequently dredges in and adjacent to the RMPF Cooling Water Intake Structure to maintain the appropriate water depths for the intake screens. Neither of these activities have an impact on the baseline water conditions evaluated in the vicinity of the intake.

Attachment S Worksheet 11.3, page 81 Previously conducted studies or studies obtained from other facilities addressing technology efficacy, through-facility entrainment survival, and other entrainment studies with the application.

§122.21(r)(7) Entrainment Performance Studies Entrainment monitoring studies have been performed at the South Texas Project Electric Generating Station (STPEGS) that included the source water makeup from the Colorado River and the Main Cooling Reservoir (MCR).

(i) Submit a description of any biological survival studies conducted at the facility and a summary of any conclusions or results, including the following: site-specific studies addressing technology efficacy, through facility entrainment survival (distinguished for eggs and larvae), entrainment analyses, or studies conducted at other locations including a justification as to why the data are relevant and representative of conditions at the facility.

a. The Construction Phase (CP) of the Final Environmental Statement (FES) for the STPEGS included a requirement from the Nuclear Regulatory Commission (NRC) to conduct a two-phase monitoring program related to the ecological conditions in the lower Colorado River. 1 Phase1 occurred before the filling of the MCR. Phase 1 of the entrainment monitoring program was conducted from April 1975 to April 1976 and consisted of 26 sampling dates at 15 site locations with samples taken weekly from March through May, August through December, every other week during January through February and June through July.2 Phase 2 of the entrainment monitoring program was conducted adjacent to the Reservoir Makeup Pumping Facility (RMPF) at one site location from July 1983 through December 1984 during the filling of the MCR.3 McAden conducted studies to estimate entrainment impacts by collecting surface plankton samples in front of the RMPF. McAden used a hand-towed 0.5-meter (20-inch mouth diameter) ichthyoplankton net with 0.5-millimeter (0.02-inch) square mesh and swept the hand-tow parallel to the front wall of the pump structure. The most commonly collected species included the zoeae and juveniles of Harris mud crabs (Rhithropanopeus harrisii), river shrimp (Macrobrachium ohione), and white shrimp (Litopenaeus setiferus). McAden collected the eggs and larvae of two fish species, bay anchovy (Anclwa mitchilli) and mosquito fish (Gambusia affinis). McAden also conducted plankton tows in the Colorado River near the RMPF. The most commonly collected species of fish eggs and larvae included bay anchovy, Gulf menhaden (Brevoortia patronus), and Atlantic croaker (Micropogonias undulatus). Based on the McAden et. al entrainment study (1984;1985), the NRC estimated that entrainment losses would be approximately 10 percent of the organisms passing the RMPF. 3 This value represents the loss of organisms in the influence of the tidal flow in the river and does not represent the entire populations of those species in the lower Colorado River.

b. STP Nuclear Operating Facility (STPNOC) has not conducted impingement and/ or entrainment studies on the Colorado River, a water of the U.S., since its 1983to1984 1 U.S. Nuclear Regulatory Commission (NRC) 1975.

Attachment S Worksheet 11.3, page 81 study. However, STPNOC conducted impingement and entrainment studies at the Reservoir Circulating Water Intake Structure on the MCR, not a water of the U.S., from May 2007 through April 2008. 4 The objective of the study was "to characterize the aquatic species within the MCR, and to evaluate impingement and entrainment impacts to establish, to the extent possible, relationships between the presence of aquatic organisms and the current (STP, Units 1and2) intake design and operating parameters". ENSR collected entrainment samples over a 24-hour period, twice per month from May through September and once per month from October through April.

ENSR collected entrainment samples by placing 0.363-millimeter (0.014-inch) plankton nets behind the trash bars at the CWIS. ENSR pumped water from a depth of approximately 12 feet (3.7 meters) through a buffering chamber at flows up to 10,800 gallons per hour or 180 gallons per minute (gpm). ENSR operated the pumps four times per day, for approximately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> per event, for a volume of 100 cubic meters (3,500 cubic feet) of water per 24-hour period. ENSR (2008a) collected 207,696 organisms representing nine different fish families and 12 different classes of invertebrates. The most commonly impinged taxa included Harris mud crab (68 %) and unidentified decapod zoea (free swimming larvae) (15% ). Ichthyoplankton, or fish eggs and larvae, comprised less than 1 % of all entrained organisms. ENSR reported the highest entrainment rates from April through June and the lowest from December through March. Entrainment of threadfin shad and mud crabs was highest in late spring and summer with the entrainment of silversides highest in summer.4 4 ENSR 2008.
