COMPOSITE SAMPLING (24-HOUR)
1. STANDARD PROVISIONS Part II Page 3 of 26 Permit No. LA0003336 AI No. 3271

Unless otherwise specified in this permit, the term 11 24-hour composite sample" means a sample consisting of a minimum of four (4) aliquots of effluent collected at regular intervals over a normal 24-hour operating day and combined in proportion to flow or a sample continuously collected in proportion to flow over a normal 24-hour operating period. 2. VOLATILE COMPOUNDS


### For the "24-hour composite" sampling of volatile compounds using EPA Methods 601, 602, 603, 624, 1624, or any other 40 CFR Part 136 (See LAC 33:IX.4901) method approved after the effective date of the permit, the permittee shall manually collect four (4) aliquots (grab samples) in clean zero head-space containers at regular intervals during the actual hours of discharge during the 24-hour sampling period using sample collection, preservation, and handling techniques specified in the test method. These aliquots must be combined in the laboratory to represent the composite sample of the discharge. One of the following alternative methods shall be used to composite these aliquots.

a. Each aliquot is poured into a syringe. The plunger is added, and the volume in the syringe is adjusted to 1-1/4 ml. Each aliquot (l1/4 ml.) is injected into the purging chamber of the purge and trap system. After four (4) injections (total 5 ml.), the chamber is purged. Only one analysis or run is required since the aliquots are combined prior to analysis.
b. Chill the four (4) aliquots to 6 Degrees Centigrade. These aliquots must be of equal volume. Carefully pour the contents of each of the four aliquots into a 250-500 ml. flask which is chilled in a wet ice bath. Stir the mixture gently with a clean glass rod while in the ice bath. Carefully fill two (2) or more clean 40 ml. zero headspace vials from the flask and dispose of the remainder of the mixture. Analyze one of the aliquots to determine the concentration of the composite sample. The remaining aliquot (s) are replicate composite samples that can be analyzed if desired or necessary.

c. Alternative sample compositing methods may be used following written approval by this Office.
The individual samples resulting from the application of these compositing methods shall be analyzed following the procedures specified for the selected test method. The resulting analysis shall be reported as the daily composite concentration.

### OTHER REQUIREMENTS (continued) Part II Page 4 of 26 Permit No. LA0003336 AI No. 3271
As an option to the above compositing methods, the permittee may 

### manually collect four (4) aliquots (grab samples) in clean zero headspace containers at regular intervals during the actual hours of 

### discharge during the 24-hour sampling period using sample collection, preservation, and handling techniques specified in the test method. A separate analysis shall be conducted for each discrete grab sample following the approved test methods. The determination of daily composite concentration shall be the arithmetic average (weighted by 

### flow) of all grab samples collected during the 24-hour sampling period. F. 40 CFR PART 136 (See LAC 33:IX.4901) ANALYTICAL REQUIREMENTS Unless otherwise specified in this permit, monitoring shall be conducted according to analytical, apparatus and materials, sample collection, preservation, handling, etc., procedures listed at 40 CFR Part 136, and in 

### particular, Appendices A, B, and C (See LAC 33:IX.4901). G. FLOW MEASUREMENT "ESTIMATE" SAMPLE TYPE If the flow measurement sample type in Part I is specified as "estimate", flow measurements shall not be subject to the accuracy provisions established 

### at Part III.C.6 of this permit. The daily flow value may be estimated using best engineering judgment. 

### H. pH RANGE EXCURSION PROVISIONS
Where a permittee continuously measures the pH of wastewater as a requirement or option in a Louisiana Pollutant Discharge Elimination System (LPDES) permit, the permittee shall maintain the pH of such wastewater within the range set forth in the permit, except that excursions from the range are 

### permitted, provided:
1. The total time during which the pH values are outside the required range of pH values shall not exceed 446 minutes in any calendar month; and 

### 2. No individual excursion from the range of pH values shall exceed 60 minutes.
For the purposes of this section, an "excursion., is an unintentional and temporary incident in which the pH value of discharge wastewater exceeds the

## 1. Company CommentRegarding TotalMaximum Daily Loads (TMDLs)- Section I A. Overview

a. Company Comments A.l and 

### A.2 Sasol North America, Inc. does not object to the requirements to monitor only for the TMDL-based parameters for the Calcasieu River and Bayou Verdine TMDLs. Although Sasol believes no TMDLs are warranted, Sasol does not object to such monitoring for information gathering purposes. Response to Company Comments A.l 

### and 

### A.2 These TMDLs upon finalization and notice in the Federal Registerbecame part ofLouisiana's approved Water Quality Management Plan (WQMP). In accordance with LAC 33:IX. 2707.D.6, LDEQ is required to ensure that LPDES permits are consistent with the WQMP as approved by EPA under §208(b) ofthe CWA. Therefore, LDEQ must implement the TMDLs and wasteload allocations contained within into the LPDES permit. b. Company Comment

### A.3 Because Sasol's previous LPDES permit became effective on May 15, 

### 2002,just prior to the finalization ofthe Total Maximum Daily Load for Toxics for the Calcasieu Estuary, the wasteload allocations assigned to Sasol in such TMDL are being incorporated in Sasol's LPDES permit for the first time through this permit renewal. These wasteload allocations are to become effective uponthe date ofthe renewed permit. Response to Company Comment

### c. Company Comment A.4 It

### is Sasol's understanding that any changes made to the TMDL that would result in removal or establishment ofless stringent limitations than those established in this renewal permit would constitute an exception to LAC 33:IX.2707.L. Additionally, Sasol anticipates that LDEQ will make any necessary changes resulting from a revocation or modification of the TMDL for Toxics for the Calcasieu Estuary upon renewal or arequest for modificationofLPDES permit LA0003336. Sasol requests that LDEQ confirm Sasol's understanding, as set forth in Comment A.4, in LDEQ'sresponse to comments. 

### Response to Company CommentA.4 LDEQ concurs that changes resulting in the removal or establishment of less stringent TMDL limitations than those established in arenewal permit would constitutean exceptionto LAC 33:IX.2707.L. Shouldthe WQMP be updated to remove orrevise these TMDLs, the Water Permits Division will either incorporate the changes into the new permit upon reissuance or by request ofapermit modification. 

### B. EPA TMDLs for the Calcasieu Riverffiayou Verdine Company Comments B.I, 8.2, 8.3, 8.4, and 8.5 Sasol has identified numerous reasons why TMDLs contained in the Calcasieu TMDL are invalid and should be revoked or revised. Sasol has also requested that numerous materials supporting their objection to the Calcasieu TMDL be included as part ofthe administrative record. 

### Response to Company Comments B.I,8.2,B.3, 8.4, and 8.5 These comments are related to the validity and legality ofthe Calcasieu TMDLs which have been implemented into the LPDES permit. These TMDLs, upon ·finalizationand notice in theFederalRegister,becamepartofLouisiana's approved Water Quality Management Plan (WQMP). In accordance with LAC 33:IX. 2707.D.6, LDEQ is required to ensure that LPDES permits are consistent with the WQMP as approved by EPA under§208(b) ofthe CW A. Therefore, LDEQ must implement the TMDLs and wasteload allocations contained within the LPDES permit. Any commentsregarding the LPDES Permit are part ofthe administrative record.

a. Company Comment C.l Sasol requests revisions to the language in Part II, Sections K and L. 

### Both sections contain the following paragraph: Federal regulations under 40 CFR 130.7 reqUJre the State to incorporate all final TMDLs into its current Water Quality Management Plan (WQMP). The State is also required to ensure consistency with the WQMP requirements approved by EPA under Section 208(b) ofthe Clean WaterAct (CWA), as cited under LAC 33.IX.2707.D.6. Since the requirements established in the Final TMDL (Federal Register Notice: Volume 67, Number 114, pages 40735

- 40737, 6/13/2002) are water quality-based effluent limitations that are part of the State's current Water Quality Management Plan (Volume 8), and are more stringent than the technology based effluent limitations (unless otherwise noted), the TMDL waste load allocations must remain in the permit. Sasol requests that these sections be changedto read: Federal regulations under 40 CFR 130.7 require the State to incorporate all final TMDLs into its current Water Quality Management Plan (WQMP). Upon finalization in Federal Register Notice: Volume 67, Number 114, pages 40735-40737, 6113/2002, the TMDL for Toxics in the Calcasieu Estuary (Final TMDL) became part of Louisiana's approved WQMP.

Where the requirements established inthe Final TMDLare more stringentthan the technology based effluentlimitations, the waste load allocations established bythe Final TMDLwill remainin the permit. However, ifat any time the Final TMDL is revoked or modified so that any established total maximum daily load and/or wasteload allocation is revoked or modified, the permittee may request that this permit be modified or revoked and reissued to maintain consistency with the State's WQMP.

Company Comment Regarding Other Water Quality Based Effluent Limitations

- Section II Several new and/or more stringent water quality based effluent limitations have been established in the renewal permit at Outfalls 001, BOI, and COl. Particularly Hexachlorobenzene at Outfall 001; Total Nickel, I,2-Dichloroethane, Total Cyanide, Carbon Tetrachloride, I,1-Dichloroethylene, Tetrachloroethylene, Hexachlorobenzene, and Hexachlorobutadiene at Outfall BOI; and Total Cyanide, Hexachlorobenzene, and Hexachlorobutadiene at Outfall COl. While monitoringand reporting for Total Nickel and I,2-Dichloroethane at Outfall BOI is required under the Calcasieu TMDL, effluent limitations have been established for these two parameters and each ofthe parameters listed above as a result ofwater quality screens conducted during permit development at Outfalls 001, BOI, and COl. These water quality screens are contained in Appendix B of the draftpermitFact Sheet and Rationale. Both Sections 301 ofthe Clean Water Act and Louisiana's Implementation Plan (WQMP Volume 3), Permitting Guidance Document for Implementing Louisiana's Surface Water Quality Standards (Water Quality Standards Implementation Document), allow complianceschedulesto meetnewwaterqualitybasedeffluentlimitations. Indeed, Section 9ofthe Water Quality Standards Implementation Documentprovides: The Office ofEnvironmental Services may include compliance schedules to allow adequate time to meet water quality based limits and progress reports will generally be required. Compliance schedules will generally be no longerthan three years. Sasol hereby requests that a three-year compliance schedule be established in the final
