Engineering Report No. WF3-IC-15-00001 Rev 1 Page 4 of 82 1.0 Introduction Technical Specification 6.9.1.9 for the Waterford SES Unit 3 requires Entergy Operations Inc. to perform surveys and analyses of major industries in the vicinity of the plant which have significant inventories of hazardous chemicals on site to determine the impact on safety and submit the results to the NRC at least every four years. Technical Specification 6.9.1.10 for the Waterford SES Unit 3 requires Entergy Operations, Inc. to perform a survey of major pipelines (four inches in diameter or greater) within a 2-mile radius of the site which contain explosive or :flammable materials and may represent a hazard to Waterford

3. The results are required to be submitted to the NRC at least once every four years and need to include scaled engineering drawings or maps which indicate the pipeline locations. This report was prepared in 2015 and serves as documentati6noflhe projected 2016-surveys;--screening analyses, and maps-wliich indicate pipeline locations. Chemicals that require further evaluation using TOXCHM are listed in Section 4.0, Summary of Results. This report builds on the analyses done in previous surveys and takes credit for evaluations that have been performed in the past. It is similar in structure and approach to the one developed in 2012 [Ref. 3]. Differences are discussed in Section 2.1.2, as well as throughout the report.

Revision 1 of this report makes several changes. Since the IDLH value for propane is based on the lower explosive limit (LEL) and not on toxicity, its designation is returned to a simple asphyxiant, which is consistent with the 2012 survey [Ref. 3]. The chemicals ethanolamine, toluene diisocyanate, naphthalene, and hydrogen peroxide were previously listed as requiring TOXCHM analysis. However, the vapor pressure of these chemicals is <10 torr so this analysis is not required. Note that hydrogen peroxide has a vapor pressure of five (5) torr according to the NIOSH [Ref. 14]. The quantity of bromine was revised because it was incorrectly reported by Motiva. A more accurate quantity of hydrogen sulfide at Union Carbide is now reported to remove unnecessary conservatism. Benzene, also stored at Union Carbide, was added to the Summary of Results Table 4-1. This was analyzed and identified in Table 2-3 correctly in Rev. 0. Other changes include minor rounding discrepancies, several changes to tables for consistency, as well as several changes to dispositions for screened out chemicals. There are no new or increased quantities of chemicals that require TOXCHM analysis.

2.0 Hazardous Chemical Survey This section includes the surveys and analyses of major industries in the vicinity ofWaterford 3 which have significant inventories (i.e., > 500 lb) of hazardous chemicals on site. The quantities of chemicals stored, processed, or transported and the disposition of these chemicals are presented. The disposition codes in Table 2-1 describe how chemicals are dispositioned. The results of the dispositioning are included in Table 2-3 and Table 2-9 through Table 2-13 of this report. Chemicals were evaluated against their respective Immediately Dangerous to Life or Health (IDLH) concentrations as specified in Reg. Guide 1.78 [Ref. 1].

IDLH values for chemicals were taken from the National Institute for Occupational Safety and Health (NIOSH) chemical tables [Ref. 2]. Chemical data was taken from the National Oceanic and Atmospheric Administration [Ref. 7] unless otherwise noted.

2. l Survey of Local Industries

2. 1.1 Conduct of Survey In order to determine the industrial facilities that store or process hazardous chemicals within a 5-rnile radius of Waterford 3, information from the previous survey [Ref. 3] was used along with information gathered from the Emergency Preparedness Department of St. Charles Parish and the Emergency Operations Center of St. John the Baptist Parish, which encompass all areas within a 5-mile radius of Waterford 3. The facilities that were identified are listed in Table 2-2 along with the distance and direction from Waterford 3. Some of the distances have changed slightly from the 2012 survey [Ref. 3] based on the latest information provided by the parishes. The locations are shown on a map of the surrounding area in Figure 2-1. The Bouchereau Oil facility is no longer included because it is not operational.

Each facility in Table 2-2 was first contacted by telephone. Once the requirements of the survey were discussed, follow-up communication was conducted via email. In most cases, each company was sent copies of the information that they provided in the previous survey. Each company was asked to indicate any changes or omissions from the previously reported data or to confirm that the data was still valid.

2.1.2 Significant Changes from the Previous Survey There are several significant changes from the 2012 survey [Ref. 3] that should be noted. First, gasoline does not have an IDLH value, and therefore the designation of gasoline throughout this survey is now not toxic (NT). Gasoline stations were previously included for completeness but have since been removed because the risk to control room habitability is insignificant.

Isopentane also does not have an IDLH value and therefore the designation of isopentane throughout the report has been changed to not toxic (NT). However, n-pentane is toxic and therefore any unspecified pentane mixture is conservatively assumed to be comprised of only n-pentane.

Some of the weights presented in Table 2-3 have been updated from the 2012 survey [Ref. 3] due to differences in densities from the latest chemical information sheets [Ref. 7]. These changes are not noted since the differences are small, the information provided by the sites is the same, and they do not require additional analysis.

2.L3 Survey Results and Screening The information provided by the responding companies is discussed in the following sections. Table 2-3 contains all the data collected. New chemicals or those that have increased in amount stored have an updated status listed in the last column, and indicate they either require a TOXCHM analysis or are screened out due to one of the disposition criteria in Table 2-1. For those which are toxic, a screening test by quantity

Engineering Report No. WF3-IC-15-00001 Rev Page 7 of 82 based on Table C-2 from Regulatory Guide 1.78 [Ref 1] is performed as shown below. If the ammmt stored is less than the maximum allowed quantity, it does not require a TOXCHJ\tI evaluation.

X = Q (1000 lbs) x Fe X P x Fa Where: X =Maximum allowed quantity, in pounds Q =Value from Table C-2 of Reg. Guide 1.78 [Ref. 1] for a Type C control room Fe= Concentration correction factor P = Pasquill stability category Fa= Air exchange rate correction factor The Pasquill stability category (P) is 0.4 per Section 2.2.3.3.1 of the WF3 FSAR [Ref. 6]. The concentration correction factor Fe is defined below using the 50 mg/m3 base IDLH from Reg. Guide 1.78

[Ref 1].

Where: Cm= IDLH Value, in mg/m3 To calculate a concentration correction factor (Fe) in parts per million (ppm) instead of mg/m3, the equation for Fe is adjusted as shown below. Note the 24.45 liters per mole is taken from the National Institute for Occupational Safety and Health (NIOSH) [Ref 11].

CxM )

Fc = ( 24.4S x SO [:~]

Where: C = IDLH Value, in ppm M = Molecular weight of the chemical, in grams per mole The air exchange rate at WF3 is 0.86 volumes per hour per hour from Section 2.2.3.3.1 of the WF3 FSAR

[Ref. 6] as compared with 1.2 volumes per hour in Reg. Guide 1.78 [Ref. 1]. Thus the air exchange rate correction factor (Fa), which is inversely proportional to the weights, is calculated below.

2.1.3 .2 Air Liquide Taft Air Liquide reported that the information from the 2012 survey [Ref. 3] for their Taft facility remain~ valid.

No changes or additional analyses are required.

2.l.3.3 ArcelorMittal Steel ArcelorMittal Steel confirmed that they do not store or process any hazardous chemicals at their plant. No analysis is required.

2.1.3 .4 CGB Marine Supply CGB Marine supply reported that the amount of gasoline and diesel fuel are the same from the 2012 survey

[Ref. 3]; however, they also store liquid oxygen and propane. Oxygen is not toxic. Propane is a simple asphyxiant. Therefore, no further analysis is required.

2.1.3.5 Entergy Little Gypsy SES Little Gypsy reported that there were no changes in the amounts of any chemicals from the 2012 survey

[Ref. 3], although they no longer received shipments of ammonia. Therefore, no further analysis is required.

2.1.3.6 Entergy Waterford 1, 2, and 4 Waterford 1 and 2 reported that the amounts of ammonia and hydrogen stored on site have not changed since the 2012 survey [Ref. 3]. Carbon dioxide was removed from the survey since it is no longer stored in bulk. They also reported they store sulfuric acid and caustic (sodium hydroxide). Both have vapor pressures less than 10 torr at 100°F [Ref. 7] and can be classified as non-volatile. Therefore, no further analysis is required.

Waterford 4 reported that the amount of diesel fuel on site has not changed. Therefore, no further analysis was required. Lube oil was also removed from this survey because it is non-toxic .

.2:1 .3.7 Enterprise Products Norco Fractionation Plant Enterprise Products reported that the information from the 2012 survey [Ref. 3] remains valid. No changes or additional analyses are required.

Engineering Report No. WF3-IC-15-00001 Rev I Page 9 of 82 2; l.3;8 Galata Chemicals Galata Chemicals was formerly known as Chemtura. Galata reported that of the amounts of ammonia (anhydrous), methyl acrylate, formic acid, heptane, and hydrochloric acid have increased from the previous survey. They now store monochloroacetic acid, which is not toxic, and hydrogen peroxide, which is non-volatile (V). They also no longer store hydrogen sulfide. The chemicals listed which are toxic are evaluated as shown below.

Ammonia (anhydrous) (IDLH: 300 ppm, MW: 17.03):

X .=: 9.~_6(2.5)(~_0_0)(17.03) =::= 5,875 lbs. < _156,000 lbs.

Since the stored quantity, 156,000 lbs., is greater than the maximum allowable quantity, 5,875 lbs., further analysis using TOXCHM will be required.

Methyl Acrylate (IDLH: 250 ppm, MW: 86.09):

X = 0.46(2.5)(250)(86.09) = 24,751 lbs. < 72,000 lbs.

Since the stored quantity, 72,000 lbs., is greater than the maximum allowable quantity, 24,751 lbs., further analysis using TOXCHM will be required.

Formic Acid (IDLH: 30 ppm, MW: 46.03):

X = 0.46(2.5)(30)(46.03) = 1,588 lbs. < 150,000 lbs.

Since the stored quantity, 150,000 lbs., is greater than the maximum allowable quantity, 1,588 lbs., further analysis using TOXCHM will be required.

Heptane (IDLH: 750 ppm, MW: 100.21):

X = 0.46(2.5)(750)(100.21) = 86,431 lbs. < 150,000 lbs.

Since the stored quantity, 150,000 lbs., is greater than the maximum allowable quantity, 86,431 lbs., further analysis using TOXCHM will be required.

Hydrochloric Acid (IDLH: 50 ppm, MW: 36.46):

X = 0.46(2.5)(50)(36.46) = 2,096 lbs. < 20,000 lbs.

Since the stored quantity, 20,000 lbs., is greater than the maximum allowable quantity, 2,096 lbs., further analysis using TOXCHM will be required.

2.1.3.9 Koch Nitrogen Koch reported they no longer store 500 gallons of gasoline on site and have added several new chemicals (nitrogen, oxygen, compressor oil, and diesel fuel) since their 2012 survey. Oxygen and compressor oil are not toxic (NT). Nitrogen is a simple asphyxiant. Diesel fuel has a vapor pressure less than 10 torr at 100° F

Engineering Report No. WF3-IC-15-00001 Rev Page 10 of 82

[Ref. 7] and can be classified as non-volatile (V). Koch also reported the amount of ammonia (anhydrous) on site has increased as shown below.

Ammonia (IDLH: 300 ppm, MW: 17.03):

X = 0.46(1.0)(300)(17.03) = 2,350 lbs. < 98,784,000 lbs.

Since the stored quantity, 98,784,000 lbs., is greater than the maximum allowable quantity, 2,350 lbs.,

further analysis using TOXCHM is required.

2.1.3. l(} Mosaic Phosphates Mosaic reported that there were no changes in the amounts of any chemicals from the 2012 survey [Ref. 3]

and that they now store 500 gallons of diesel fuel at their Taft facility. Diesel fuel has a vapor pressure less than 10 torr at 100° F [Ref. 7] and can be classified as non-volatile (V). Therefore, no further analysis is required.

2.1.3 .11 Motiva Enterprises Motiva reported that they do not store any new chemicals, although some of the amounts have changed.

Those which are toxic are shown below.

Ethyl Mercaptan (IDLH: 500 ppm, MW: 62.1 g/mol):

X = 0.46(33)(500)(62.1) = 471,339 lbs. > 34,000 lbs.

Since the stored quantity, 34,000 lbs., is less than the maximum allowable quantity, 471,339 lbs., no further analysis is required.

Methanol (IDLH: 6,000 ppm, MW: 32.04 g/mol):

X = 0.46(33)(6,000)(32.04}= 2,918,203 lbs. > 18,000 lbs.

Since the stored quantity, 18,000 lbs., is less than the maximum allowable quantity, 2,918,203 lbs., no further analysis is required.

Methyl Mercaptan (IDLH: 150 ppm, MW: 48.1 g/mol):

X = 0.46(33)(150)(48.1) = 109,524 lbs. > 38,000 lbs.

Since the stored quantity, 38,000 lbs., is less than the maximum allowable quantity, 109,524 lbs., no further analysis is required.

The amount of chlorine stored on site was reported to have increased to 114,000 lbs. This increased amount was reanalyzed according to Reg. Guide 1.95 [Ref. 4]. Based on Table 1 of Reg. Guide 1.95, at a distance of 6,560 ft, the maximum amount of chlorine is 1,200,000 lbs. The distance from the Motiva site to the Waterford 3 site is greater than 18,000 ft. Since the mass of chlorine is less than the maximum and the distance is greater than that presented in Table 1 of Reg. Guide 1.95, no additional analysis is required.

Engineering Report No. WF3-IC-15-00001 Rev Page 11 of 82 2; L3.-12. Hexion me.

Hexion me. was formerly known as Momentive Specialty Chemicals. Hexion reported the only changes since the 2012 survey [Ref. 3] are the quantities stored of toluene and hydrochloric acid have decreased.

Therefore, no further analysis is required.

2, 1:3.13 Occidental Chemical Occidental Chemical reported that there were no changes in the amounts of any chemicals from the 2012 survey [Ref. 3], although chloroform is now shipped in 2,000 gallon tanks instead of55 gallon drnms. Note

___the weight of hydrochloric .i::t~id_presented_in TajJle 2-:4 ofthe.2012 report [Ref. 3] was incorr~ft_}[owever, the correct amount was analyzed in Toxic Chemical Evaluation Calculation, EC-S97-020 [Ref. 13]. No additional analysis is required.

2. 1.3. l 4 Praxair Distribution Praxair Distribution reported that the information from the 2012 survey [Ref. 3] remains valid. No changes or additional analyses are required.

2.l.3.l 5 Shell Norco Chemical Plant- East Site Shell reported that the quantities of many chemicals have changed, and they no longer store chlorine. Two quantities of the flammable mixtures have increased from what was previously reported at the East Site of their Norco facility. Since individual component percentages were not provided, each component will be conservatively analyzed as comprising the total amount of the mixture. For the first mixture, isobutane and butane do not have an IDLH, so only 1,3-butadiene is evaluated.

1,3-Butadiene (IDLH: 2,000 ppm, MW: 54.09 g/mol [Ref. 8])

X = 0.46(33)(2000)(54.09) = 1,642,172 lbs. > 24,000 lbs.

Since the stored quantity, 24,000 lbs., is less than the maximum allowable quantity, 1,642, 172 lbs., no farther analysis is required.

For the second mixture, both isopentane and isoprene do not have an IDLH value and thus do not require farther evaluation, so only pentane is evaluated.

Pentane (IDLH: 1,500 ppm, MW: 72.15 g/mol)

X = 0.46(33)(1500)(72.15) = 1,642,856 lbs. > 100,000 lbs.

Since the stored quantity, 100,000 lbs., is less than the maximum allowable quantity, 1,642,856 lbs., no farther analysis is required.

2.1.3.. 16 Shell Norco Chemical Plant - West Site Shell reported they store the flammable mixture from the 2012 survey [Ref. 3]. None of the components in the flammable mixture have IDLH values and therefore no farther analysis is required.

Engineering Report No. WF3-IC-15-00001 Rev Page 12 of 82 2.1.3.17 St. Charles Parish Waterworks -District 1 St. Charles Parish reported that the information provided in the 2012 survey is up to date, however the amount of chlorine stored in the largest container is actually 1 ton (2000 pounds) instead of 5 tons. The amount of sulfuric acid, purate, and hydrofluorosilicic acid are still the same. Therefore, no further analysis is required.

2. l.3J8: St. John the Baptist Parish Waste Water Treatment River Road St. John the Baptist Parish reported that the information from the 2012 survey [Ref. 3] remains valid. No

- changes -Or additional analyses are required. They also provided shipment.information, which is discussed-in Section 2.2.5.

2.1.3.19' Union Carbide Corp.

Union Carbide, a wholly owned subsidiary of the Dow Chemical Company, provided their latest facility Tier II report. They also reported the Cypress Catalyst Plant was sold to W. R. Grace, which is now addressed in Section 2.1.3 .21. The Tier II report contains a listing of all chemicals and chemical mixtures contained on site. Based on this report, there are numerous changes from the 2012 survey [Ref. 3]. 2-methoxyethanol, acrylonitrile, cyclohexane, and propylene are no longer stored on site. 1-hexene, butyl acrylate, butyraldehyde, methoxydihydropyran, pyridinium acetate, and vinyl methyl ether were all previously designated as toxic but do not have an IDLH value and therefore have been updated to be non-toxic (NT). The amounts of 1,3-butadiene, acrolein, ammonia, ethyl acrylate, ethylene oxide, ethylenediamine, hydrogen chloride, isobutyl alcohol, isopropyl ether, methanol, and methyl mercaptan stored on site have all increased and therefore further analysis using TOXCHM will be required. Union Carbide also stores a large number of chemicals that were not included in the previous survey. Of these, thirteen are toxic and evaluated. Note, dripolene (pyrolysis gas) was included in the 2012 survey [Ref. 3]

but was removed from this report since it does not have a unique IDLH. However, several of its components-do and therefore dripolene was split into its components and each was evaluated separately. The components of dripolene that now require analysis are 2-propanone (acetone), benzene, dimethylbenzene (xylene), hexane, and toluene. These are evaluated below along with the thirteen new toxic chemicals referenced above. All of the dripolene components will be listed and designated with an (b), if dripolene is their primary source, in Table 2-3.

2.1.3.20* Valero Refining Valero Refining provided updated information on the chemicals stored at their site. Valero reported the largest quantities of 1,3-butadiene and isopropyl benzene have increased, which are evaluated. The stored quantity of phenol and biphenol also increased; however, the vapor pressure is less than 10 torr at 100°F

[Ref. 7] and therefore no further analysis is required. Likewise, the vapor pressure of naphthalene is less than 10 torr [Ref. 7] and therefore the designation was changed to non-volatile (V). 2,2,4-trimethylpentane, which is not toxic (NT), is also now stored.

1,3-Butadiene (IDLH: 2,000 ppm, MW: 54.09 g/mol [Ref. 8]):

X = 0.46(60)(2000)(54.09) = 2,985,768 lbs. > 1,826 lbs.

Since the stored quantity, 15,283 lbs., is less than the maximum allowable quantity, 2,985,520 lbs., no further analysis is required.

2;1.3;21 W.R. Grace The W. R. Grace SHAC Plant, which was previously the Union Carbide Corp Cypress Catalyst Plant, reported that the information from the 2012 survey [Ref. 3] remains valid. The only change is to Titanimn Tetrachloride, which does not have an IDLH value and therefore the designation was changed to not toxic (NT) .

.2J.3.22 Waguespack Oil Company Waguespack Oil reported that the information from the 2012 survey [Ref. 3] for their facility in LaPlace remains valid. Note the values in Table 2-4 of the 2012 report [Ref. 3] were incorrectly presented as volumes instead of weights. This has been corrected and no changes or additional analyses are required.

Engineering Report No. WF3-IC-15-00001 Rev Page 16 of 82 2.1.3.23 Western International Western International reported that the information from the 2012 survey [Ref. 3] for their bulk supply facility in Taft remains valid, although the previous acetylene value of 100,000 scf is for the whole site.

The single largest container only holds 6,800 scf. Since the previous 100,000 scfvalue is more conservative, no additional analyses are required.

Engineering Report No. WF3-IC-15-00001 Rev 1 Page 37 of 82 2~2 Transportation Surveys Five significant routes used to transport hazardous materials in the vicinity of Waterford 3 were identified in the course of this analysis. These include three railroads that lie within five miles of the plant, the Mississippi River, and the nearest highway: Louisiana Route 18, also known as River Road. Listings of hazardous materials transported in the Waterford 3 vicinity were obtained from the Army Corps of Engineers, local industries, and the three railroad companies: Kansas City Southern Railway; the Union Pacific Railway; and the Canadian National Railway.

The total tonnage of each category of hazardous material transported on the Mississippi River by the

• - *-**--**-Waterford-3-site in 201-3, which is between-River Mile 129and129.9,-was-obtained from the U.S. Army---

Corps of Engineers. See Section 2.2.4 for justification using this mileage range.

Information on possible shipments of hazardous materials on LA Route 18 was obtained from local industries.

The same equation that was used in Section 2.1.3 was used in this section. However, since transportation volumes are more easily calculated in tonnage vs. lbs. (as in Section 2.1 ), the equation was slightly modified to determine the maximum allowed quantity in tons, as shown below.

4. 6 x 10-4 x Q x C x M x = ---------- 2 Where:

X = Maximum Allowed Quantity Q = Value from Table C-2 of Reg. Guide 1. 78 [Ref. 1] for a type C control room C = IDLH Value, ppm M =Molecular Weight of the Chemical A standard rail car is assumed to be carrying 100 tons of cargo, which is significantly higher than the 61.0-66.6 average tons per carload range from 1995-2005 according to the Bureau of Transportation Statistics [Ref. 12]. Therefore, ifthe maximum allowed quantity ofa chemical is less than 100 tons, it requires further evaluation using TOXCHM. This is consistent with the 2012 report [Ref. 3].

2:2;1 Union Pacific Railroad The Union Pacific Railroad is the nearest railroad to Waterford 3. Union Pacific tracks pass within 0.45 miles of the control room air intake. Entergy was provided updated information from Union Pacific. The information provided was a listing that included all hazardous cargo transported anywhere on the line that runs between Avondale, which is just outside of New Orleans, and Addis, which is a few miles south of Baton Rouge. The report lists the number of shipments of each of the commodities in 2014 along with the HazMat Response Code, product description, and total number of loads shipped. The raw data provided by Union Pacific Railroad is presented in Table 2-9.

The thirteen (13) hazardous chemicals listed in Table 2-4 were added during this survey or have increased in the number of shipments to above 3 0 since the last survey. Each of these shipments were analyzed as a

Engineering Report No. WF3-IC-15-0000I Rev Page 38 of 82 stationary source via the equation shown above. If it was determined that there were at least 30 shipments in the previous survey, further analysis is not required because it was already evaluated.

Engineering Report No. WF3-IC-15-00001 Rev 1 Page 39 of 82 2;2.i Kansas City Southern Railway The tracks of the Kansas City Southern Railway (KCSR) are on the east bank of the Mississippi, nmiheast of Waterford 3, and pass within 3 .25 miles of the control room air intake. A listing of hazardous material shipments that traveled through St. Charles Parish and St. John the Baptist Parish in 2014 was obtained from KCSR. The raw data provided by Kansas City Southern Railway, which includes the Standard Transportation Commodity Code (STCC), product description, and total number of loads shipped and the screening disposition is presented in Table 2-10.

The hazardous chemicals listed in Table 2-5 were added during this survey or have increased in number of shipments to above-30 since the last survey. These shipments were analyzed as a stationary source via the equation shown in Section 2.2. If it was determined that there were at least 30 shipments in the previous survey, further analysis is not required because it was evaluated in the previous report [Ref. 3].

• Per Ref. 9 As shown above with the given assumption of 100 tons per shipment, none of the shipped materials need to be evaluated.

2.2.3 Canadian National Railroad The Canadian National Railway has tracks on the East Bank of the Mississippi River that are northeast of Waterford 3 and pass within 2.2 miles of the control room air intake. A listing of hazardous cargo that passed Waterford 3 in 2014 was provided. The raw\ data provided by Canadian National Railway is presented in Table 2-11 and includes Proper Shipping Name, Class, UN Number, and Total Shipments.

The two (2) hazardous chemicals listed in Table 2-6 were added during this survey or have increased in number of shipments to above 30 since the last survey. Each of these shipments were analyzed as a stationary source via the equation presented in Section 2.2. If it was determined that there were at least 30 shipments in the previous survey, further analysis is not required.

• Per Ref. 9 As shown above with the given assumption of 100 tons per shipment, none of the shipped materials need to be evaluated.

2.2.4 Mississippi River Traffic The total tonnage of hazardous material, by category, that was transported in 2013 past WF3 (between River Mile 129 and 129.9 of the Mississippi River), was provided by the Army Corps of Engineers. This differs slightly from the 2012 survey [Ref. 3], in which transportation quantities between River Mile 123 and 13 7 were included. A change in law now prohibits data being given out over ranges of the river and only an individual mile segment can be requested. Given the similarity in data between this report and the previous, this smaller mileage range is acceptable and demonstrates that the majority of shipments going down the Mississippi within a five miles radius ofWF3 pass by the site. The inf9rmation provided in Table 2-12 includes Commodity ID number, substance description, and total tons shipped in 2013. There was one new material added in this survey, medicines. Radioactive material, pesticides, and wood & resin chemicals are no longer shipped. Several of the designations were also updated, denoted with an asterisk(*). The hazardous chemical listed in Table 2-7 increased in quantity since the last survey. This shipment was analyzed as a stationary source via the equation presented in Section 2.2.

• Per Ref. 9 As seen in the table above, the hazardous material requires further analysis and cannot be screened.

2.2.5 Louisiana Highway 18 Louisiana Route 18, also known as River Road, passes within 714 ft of the control room air intake. LA 18 is a local road. Through traffic uses the nearby Route 3127. The two roads run parallel to each other in the immediate vicinity of Waterford 3 and are a little more than one mile apart. Therefore, it was assumed that only shipments to or from facilities in the immediate vicinity (i.e., the respondents to the survey) would travel on LA 18. The shipments are presented in Table 2-13.

The five (5) hazardous chemical shipments listed in Table 2-8 were added during this survey, have increased in either the maximum amount in a single shipment container, or increased in frequency to greater than 10 shipments per year since the last survey and require further analysis.

Engineering Report No. WF3-IC-15-00001 Rev Page 65 of 82 3.0 Pipeline Survey The initial source of information on pipelines within 2 miles of the Waterford 3 site was the 2012 report

[Ref. 3]. The 2012 report listed 12 pipeline operators in this area. Each of these pipelines were compared against the current piping layout using the National Pipeline Mapping System (NPMS) [Ref. 5]. For those which differed significantly, the companies were contacted directly. The DCP Midstream pipeline identified in the 2012 report is no longer included in the NPMS. This was verified with DCP and therefore the line has been removed. No new pipeline companies were identified, although it was noted that Evangeline Gas Pipeline Co L.P. is now operated by Enterprise Pelican Pipeline L.P and Bridgeline is now operated by Enlink.

Table 3-1: Pipeline Operators Acadian Gas Pipeline Air Products and Chemicals Inc Bridgeline Holdings L.P.

Chevron Midstream Pipelines DCP Midstream Enterprise Operating Products LLC Enterprise Pelican Pipeline L.P.

Gulf South Pipeline Company, L.P.

NuStar Pipeline Operating Partnership L.P .

. Shell Pipeline Co., L.P.

UCAR Louisiana Pipeline Co UCAR Pipeline Incorporated The pipeline operators are discussed in the following sections. Table 3-2 provides pipeline information for each pipeline within 2 miles of the Waterford 3 plant.

3.1.l Acadian Gas Pipeline System Based on a comparison of the pipelines presented in the NPMS [Ref. 5] with the information provided in the 2012 report [Ref. 3], it was determined no changes have been made. No changes to the FSAR [Ref. 6]

are required.

3.l.2 Air Products and Chemicals Based on a comparison of the pipelines presented in the NPMS [Ref. 5] with the information provided in the 2012 report [Ref. 3], it was determined no changes have been made. No changes to the FSAR [Ref. 6]

are required.

Engineering Report No. WF3-IC-15-00001 Rev 1 Page 66 of 82 3.l .3 Bridgeline Holdings LP Enlink, who now own Bridgeline, confirmed there are no changes to the information provided in the 2012 report [Ref. 3] for the lines listed under Bridgeline Holdings LP. No changes to the FSAR [Ref. 6] are required.

3.1.4 Chevron Midstream Pipelines LLC Chevron confirmed that no changes to the information provided in the 2012 report [Ref. 3] have been made.

No changes to the FSAR [Ref. 6] are required.

3~1.5 DCP Midsfream-The DCP Midstream pipeline shown in the 2012 report [Ref. 3] is no longer shown in NPMS [Ref. 5]. This was confirmed with the site. Therefore, this line needs to be removed from the FSAR [Ref. 6].

3.1.6 Enterprise Operating Products LLC Based on a comparison of the pipelines presented in the NPMS [Ref. 5] with the information provided in the 2012 report [Ref. 3], there were two minor discrepancies. First, the location of map designators #2 &

1. 4 were adjusted slightly in Figure 3-4. Second, for the line corresponding to map designator #2, the commodity is now listed as butane instead of natural gas. Therefore, this line route needs to be updated in the FSAR [Ref. 6].

3.J .7 Enterprise Pelican Pipeline L.P.

Based on a comparison of the pipelines presented in the NPMS [Ref. 5] with the information provided in the 2012 report [Ref. 3], it was determined no changes have been made. No changes to the FSAR [Ref. 6]

are required.

3.1.8 Gulf South Pipeline Company, LP Based on a comparison of the pipelines presented in the NPMS [Ref. 5] with the information provided in the 2012 report [Ref. 3], it was determined no changes have been made. No changes to the FSAR [Ref. 6]

are required.

3.1.9 NuStar Pipeline Operating Partnership LP Based on a comparison of the pipelines presented in the NPMS [Ref. 5] with the information provided in the 2012 report [Ref. 3], it was determined no changes have been made. No changes to the FSAR [Ref. 6]

are required.

3. l. l'O Shell Pipeline Co, LP Based on a comparison of the pipelines presented in the NPMS [Ref. 5] with the information provided in the 2012 report [Ref. 3], the only change is the Norco-Taft line no longer extends as far west/northwest.

The line and the products are still the same. Therefore, this line route needs to be updated in the FSAR [Ref.

6].
