E. 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 

range set forth in the permit. 

I. MINIMUM QUANTIFICATION LEVEL (MOL) 

If any individual analytical test result is less than the minimum quantification level listed below, a value of zero ( 0) may be used for that 

individual result for the Discharge Monitoring Report (DMR) calculations and 

reporting requirements.

AI No. 3271 

significant sub-lethal effect (i.e., growth or reproduction) 

at test completion to a test species at or below the critical 

dilution. 

2. PERSISTENT LETHALITY 

The requirements of this section apply only when a toxicity test 

demonstrates significant lethal and/or sub-lethal effects at or 

below the critical dilution. 

If any valid test demonstrates significant lethal or sub-lethal 

effects to a test species at or b~low the critical dilution, the 

frequency of testing for that species is automatically increased to 

once per quarter for the term of the permit. 

a. The permittee shall conduct a total of three (3) additional 

tests for any species that demonstrates statistically 

significant lethal or sub-lethal toxic effects at the critical 

dilution or lower effluent dilutions. The additional tests 

shall be conducted monthly during the next three consecutive 

months in which discharge occurs to determine if toxicity is 

persistent or occurs on a periodic basis. The purpose of this 

testing is to determine whether toxicity is present at a level 

and frequency that will provide toxic sample results to use in 

performing a Toxicity Reduction Evaluation (TRE) . If no 

additional test failures occur during the retest monitoring 

period, the testing frequency will be once per quarter for the 

term of the permit or until another test failure occurs. The 

perm.ittee may substitute one of the additional tests in lieu 

of one routine toxicity test. A full report shall be prepared 

for each test required by this section in accordance with 

procedures outlined in Item 4 of this section and submitted 

with the period discharge monitoring report (DMR) to the 

permitting authority for review. 

b. IF LETHAL EFFECTS HAVE BEEN DEMONSTRATED: If any of the valid 

additional tests demonstrates significant lethal effects at or 

below the critical dilution, the permittee shall initiate 

Toxicity Reduction Evaluation (TRE) requirements as specified 

in Item 6 of this section. The permittee shall notify the 

Department of Environmental Quality, Office of Environmental 

Compliance - Permit Compliance Unit in writing within 5 days 

of the failure of any retest, and the TRE initiation date will 

be the test completion date of the first failed retest. A TRE 

may also be required due to a demonstration of intermittent 

lethal effects at or below the critical dilution, or for 

failure to perform the required retests.

c. IF ONLY SUB-LETHAL EFFECTS HAVE BEEN DEMONSTRATED' If any two 

of the three valid additional tests demonstrate significant 

sub-lethal effects at 75\ effluent dilution or lower, the 

permittee shall initiate the Toxicity Reduction Evaluation 

(TRE) requirements (emphasizing investigations pertaining to 

sub-lethal toxicity) as specified in Item 6 of this section. 

The permittee shall notify the Department of Environmental 

Quality, Office of Environmental Compliance Permit 

Compliance Unit in writing within 5 days of the failure of any 

retest, and the TRE initiation date will be the test 

completion date of the second failed retest. A TRE 

concentrating on sub-letha~ effects may also be required for 

failure to perform the required tests. 

d. The provisions of Item 2.a. are suspended upon completion of 

the two additional tests and submittal of the TRE Action Plan. 

3. REQUIRED TOXICITY TESTING CONDITIONS 

a.. Test Acceptance

survival equal to or greater than 80%. 

ii. The mean dry weight of surviving Mysid shrimp at the end 

of the 7 days in the control (0\ effluent) must be 0.20 

mg per mysid or greater. Should the mean dry weight in 

the control be less than 0.20 mg per mysid, the toxicity 

test, including the control and all effluent dilutions 

shall be repeated. 

iii. The mean dry weight of surviving unpreserved Inland 

Silverside minnow larvae at the end of the 7 days in the 

control (0% effluent) must be 0. 50 mg per larva or

If the conditions of Test Acceptability are met in Item 3.a 

above and the percent survival of the test organism is equal 

to or greater than 80% in the critical dilution concentration 

and all lower dilution concentrations, the test shall be 

considered to be a passing test regardless of the NOEC, and 

the permittee shall report a survival NOEC of not less than 

the critical dilution for the DMR reporting requirements found 

in Item 4 below. 

c. Dilution Water 

i. Dilution water used in the toxicity tests will be 

receiving water collected as close to the point of 

discharge as possible but unaffected by the discharge. 

The permittee shall substitute synthetic dilution water 

of similar pH, hardness and salinity to the closest 

downstream perennial water for;

AI No. 3271 

OTHER REQUIREMENTS (continued) 

ii. If the receiving water is unsatisfactory as a result of 

instream toxicity (fails to fulfill the test acceptance 

criteria of Item 3 .a), the permittee may substitute 

synthetic dilution water for the receiving water in all 

subsequent tests provided the unacceptable receiving 

water test met the following stipulations: 

(A) a synthetic dilution water control which fulfills 

the test acceptance requirements of item 3.a was 

run concurrently with the receiving water 

control; 

(B) the test indicating receiving water toxicity has 

been carried out to completion (i.e., 7 days);

4. Bypass ofTreatment Facilities 

a. Bvpass. The intentional diversion of waste streams from any portion of a treatment facility. 

b. Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause 

effluent limitations to be exceeded, but only ~ it also is for essential maintenance to assure efficient 

operation. These bypasses are not subject to the provisions of Section B.4.c. and 4.d of these standard 

conditions. 

c. Notice 

(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior 

notice to the Office of Environmental Services, Water Permits Division, if possible at least ten days 

before the date of the bypass.

(1) Bypass is prohibited, and the state administrative authority may take enforcement action against a 

permittee. for bypass, unless: 

(a) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; 

(b) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment 

facilities, retention of untreated wastes, or maintenance during normal periods of equipment 

downtime. This condition is not satisfied if adequate back-up equipment should have been 

installed in the exercise of reasonable engineering judgment to prevent a bypass which 

occurred during normal periods of equipment downtime or preventive maintenance; and, 

(c) The permittee submitted notices as required by Section B.4.c of these standard conditions. 

(2) The state administrative authority may approve an anticipated bypass after considering its adverse

permittee. An upset does not include noncompliance to the extent caused by operational error, 

improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, 

or careless or improper operation. 

b. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance 

with such technology-based permit effluent limitations if the requirements of Section B.S.c. are met. No 

determination made during administrative review of claims that noncompliance was caused by upset, 

and before an action for noncompliance, is final administrative action subject to judicial review. 

c. Conditions necessarv for a demonstration of upset. A permittee who wishes to establish the affirmative 

defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other 

relevant evidence that: 

(1) An upset occurred and that the permittee can identify the cause(s) of the upset; 

(2) The permitted facility was at the time being properly operated; and 

(3) The permittee submitted notice of the upset as required by LAC 33:JX.2701.L.6.b.ii. and Section

a. Enter upon the permittee's premises where a regulated facility or activity is located or conducted, or 

where records must be kept under the conditions of this permit. 

Enter upon the permittee's premises where a discharge source is or might be located or in which 

monitoring equipment or records required by a permit are kept for inspection or sampling purposes. 

Most inspections will be unannounced and should be allowed to begin immediately, but in no case shall 

begin more than thirty (30) minutes after the time the inspector presents his/her credentials and 

announces the purpose(s) of the inspection. Delay in excess of thirty (30) minutes shall constitute a 

violation of this permit. However, additional time can be granted if the inspector or the Administrative 

Authority determines that the circumstances warrant such action; and 

b. Have access to and copy, at reasonable times, any records that the department or its authorized 

representative determines are necessary for the enforcement of this permit. For records maintained in

"daily discharge(s)" measured during a calendar month divided by the number of "daily discharge(s)" 

measured during that month. When the permit establishes monthly average concentration effluent 

limitations or conditions, and fiow is measured as continuous record or with a totalizer, the monthly average 

concentration means the arithmetic average (weighted by fiow) of all "daily discharge(s}" of concentration 

determined during the calendar month where C = daily discharge concentration, F = daily fiow and n = 

number of daily samples; monthly average discharge = 

C1F1 + C,F, + ... + C,F, 

F, + F2 + ... + Fn

Documents containing the complete comments are located in EDMSJ The comments have been 

summarized and numbered in this document for reference. The LDEQ has responded to the 

comments relevant to the LPDES water discharge permit for Sasol North America, Inc.'s Lake 

Charles Chemical Complex (Sasol). 

1. Company Comment Regarding Total Maximum 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 Register became 

part of Louisiana'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) of the 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 of the 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 upon the date of the renewed permit. 

Response to Company Comment A.3 

This comment has been noted.

Sasol North America, Inc. I Lake Charles Chemical Complex 

RE: LA0003336, Al 3271 

Page 3 

c. Company Comment A.4 

It is Sasol's understanding that any changes made to the TMDL that would 

result in removal or establishment of less 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 a request for 

modification of LPDES permit LA0003336. 

Sasol requests that LDEQ confirm Sasol' s understanding, as set forth in 

Comment A.4, in LDEQ's response to comments. 

Response to Company Comment A.4 

LDEQ concurs that changes resulting in the removal or establishment of 

less stringent TMDL limitations than those established in a renewal permit 

would constitute an exception to LAC 33:IX.2707.L. Should the WQMP be 

updated to remove or revise these TMDLs, the Water Permits Division will 

either incorporate the changes into the new permit upon reissuance or by 

request of a permit 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 of the 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 of the Calcasieu TMDLs 

which have been implemented into the LPDES permit. These TMDLs, upon 

·finalization and notice in the Federal Register, became part of Louisiana'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) of the CW A. Therefore, LDEQ must 

implement the TMDLs and wasteload allocations contained within the LPDES 

permit. 

Any comments regarding the LPDES Permit are part of the administrative record.

C. Part II, Sections K, L, and M 

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 Water Act (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 changed to 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. As per LAC 

33.1X.2707.D.6, LDEQ is required to ensure that all LPDES permits 

are consistent with the State's WQMP a·s approved by EPA l}nder 

Section 208(b) of the Clean Water Act (CWA). Where the 

requirements established in the Final TMDL are more stringent than 

the technology based effluent limitations, the waste load allocations 

established by the Final TMDL will remain in the permit. However, 

if at 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.

Response to Company Comment C.l 

The LDEQ concurs. The language in Part II, Sections K and L has been 

changed and now reads: 

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. As 

per LAC 33.1X.2707.D.6, LDEQ is required to ensure that all LPDES 

permits are consistent with the State's WQMP as approved by EPA under 

Section 208(b) of the Clean Water Act (CWA). Where the requirements 

established in the Final TMDL are more stringent than the technology based 

effluent limitations, the waste load allocations established by the Final 

TMDL will remain in the permit. However, if at 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. 

b. Company Comment C.2 

Sasol requests that Part II, Section M be modified to read as follows 

(deletions are shown with strille through, and additions are double 

underlined): 

The Louisiana Department of Environmental Quality (LDEQ) 

reserves the right to modify or revoke and reissue this permit based 

upon any changes to established TMDL's TMDLs for this discharge 

(including removal or modification of TMDL-based limits in the 

event a TMDL is revoked or modified or applicable wasteload 

allocations are revoked or modified), or to accommodate for 

pollutant trading provisions in approved TMDL watersheds as 

necessary to achieve compliance with water quality standards. 

Therefore, prior to upgrading or expanding this facility, the 

permittee should contact the Department to determine the status of 

the work being done to establish future effluent limitations and 

additional permit conditions.

2. 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 monitoring and reporting for Total Nickel and 

I ,2-Dichloroethane at Outfall BO I is required under the Calcasieu TMDL, effluent 

limitations have been established for these two parameters and each of the parameters 

listed above as a result of water quality screens conducted during permit development at 

Outfalls 001, BOI, and COl. These water quality screens are contained in Appendix B of 

the draft permit Fact Sheet and Rationale. 

Both Sections 301 of the 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 

compliance schedules to meet new water quality based effluent limitations. Indeed, Section 

9 of the Water Quality Standards Implementation Document provides: 

The Office of Environmental 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 longer than three years. 

Sasol hereby requests that a three-year compliance schedule be established in the final 
Public Comments Response Summary for 

Sasol North America, Inc. I Lake Charles Chemical Complex 

RE: LA0003336, AI 3271 

Page 7 

LPDES permit for the above listed new and/or more stringent water quality based effluent 

limitations at Outfalls 00 I, BO I, and CO I. During the term of this 3-year compliance 

schedule, Sasol requests that the permit limits for such parameters be "report only." 

Response to Company Comment Regarding Other Water Quality Based Effluent 

Limitations - Section II 

This Office partially concurs with Sasol's request to grant a 3-year compliance schedule 

for new water quality based effluent limitations (See discussion to follow). 

Outfall 001 

In accordance with LAC 33:IX.2713.A, the LDEQ has granted Sasol a three year 

compliance schedule (Interim Schedule) that requires Sasol to comply with the OCPSF 

technology based effluent limitations for Hexachlorobenzene for the first three years of the 

permit. The three year schedule will allow the permittee time to come into compliance with 

the new water quality based effluent limitation. The Final Schedule is effective three years 

after the permit effective date and includes the new water quality based effluent limitations 

for Hexachlorobenzene.

Tetrachloroethylene, Hexachlorobenzene, and Hexachlorobutadiene. Monitoring and 

reporting requirements have been established for Total Cyanide for the first three years of 

the permit based on Best Professional Judgment. A three year schedule for the OCPSF 

technology based effluent limitations and for Total Cyanide will allow the permittee time 

to come into compliance with the new water quality based effluent limitations. The Final 

Schedule is effective three years after the permit effective date and includes the new water 

quality based effluent limitations for Carbon Tetrachloride, I, 1-Dichloroethylene, 

Tetrachloroethylene, Hexachlorobenzene, Hexachlorobutadiene, and Total Cyanide.

TMDL, Subsegment 030306. Since Sasol was not considered in this TMDL, the LDEQ has 

determined that it is appropriate to establish the water quality based effluent limitations 

effective upon issuance of the permit. This approach is consistent with implementation of 

the TMDL and ensures protection of the receiving waterbody. Compliance with TMDLs in 

LPDES permits are implemented in accordance with Louisiana's Water Quality 

Management Plan, Volume 8 which states: 
Public Comments Response Summary for 

Sasol North America, Inc. I Lake Charles Chemical Complex 

RE: LA0003336, AI 3271 

Page 9 

The LDEQ will implement finalized total maximum daily loads (TMDLs) in permits to 

require that the limits for point sources established in TMDLs be achieved: 

1. Immediately upon issuance of an LPDES permit to a new discharge 4 

(including but not limited to new discharges and expanded/increased 

discharges at existing facilities) after the TMDL has been finalized; and 

11. By every point source discharging pursuant to an existing permit within the 

earlier of three years from the effective date of the first renewal permit after 

the TMDL is finalized or six years from the finalization date of the TMDL, 

whichever occurs first. 

In accordance with LAC 33:IX. 2707.0.6, LDEQ is required to ensure that LPDES permits 

are consistent with the WQMP as approved by EPA under §208(b) of the CW A. Because 

the TMDLs for the Calcasieu River Basin were finalized in 2002, implementation of the 

TMDLs into LPDES permits must be accomplished by 2008.

3. WET Limits at Outfalls BOI and COl 

Whole Effluent Toxicity (WET) requirements are established in the renewal LPDES 

permit at Outfalls 00 I, BO I, and CO I. Outfalls BO I and CO I are emergency outfalls to be 

utilized during pump or diffuser failure and maintenance. In accordance with Footnote (*6) 

of Outfalls BOI and COl, WET testing shall be performed in accordance with the 

requirements of Part li.P in any event where discharges are diverted for a period spanning 

thirty days (of continuous or intermittent discharges). Biomonitoring results shall be

thirty days (of continuous or intermittent discharges). Biomonitoring results shall be 

reported on the DMR as Outfall TX I. 

Because the language included in Footnote (*6) does not clearly define the frequency of an 

intermittent discharge spanning a thirty-day period which would constitute a WET 

sampling event, Sasol is hereby requesting that Footnote (*6) for Outfalls BOI and COl be 

changed to read: 

Whole Effluent Toxicity Testing shall be performed in accordance with the 

requirements of Part II.P in any event where discharges (continuous or 

intermittent) are diverted to Outfall BOI/COI for an uninterrupted period of 

thirty days or greater. Biomonitoring results shall be reported on the DMR 

as Outfall TX I. 

Response to Company Comments Regarding WET Limits at Outfalls 801 and COl 

The LDEQ concurs; the footnotes have been changed and now read: 

Whole Effluent Toxicity Testing shall be performed in accordance with the 

requirements of Part II.P in any event where discharges (continuous or 

intermittent) are diverted to Outfall BO I /CO I for an uninterrupted period of 

thirty days or greater. Biomonitoring results for Outfall BO I /CO I shall be 

reported on the DMR as Outfall TX I.

IV. Permit Action/Status: 

Reason For Permit Action: 

To provide an update to the administrative record regarding the new interim and final 

schedules for Outfalls 00 I, BO I, and CO I. These changes are a result of the comments 

submitted by Sasol North America, Inc. to the draft LPDES permit that was publicly noticed 

in the Lake Charles American Press on May 12,2009. 

V. Changes from the draft to the final LPDES permit: 

A. Outfall 00 I - Sasol has requested a three year compliance schedule for new water 

quality based effluent limitations (Hexachlorobenzene). This request has been 

granted. The final permit now includes interim and final schedules with revised 

requirements for this parameter. 

B. Outfall BO I - Sasol has requested a three year compliance schedule for new water 

quality based effluent limitations (Total Nickel, I ,2-Dichloroethane, Total Cyanide, 

Carbon Tetrachloride, I, 1-Dichloroethylene, Tetrachloroethylene, 

Hexachlorobenzene, and Hexachlorobutadiene). This request has been partially 

granted. A three year compliance schedule has been granted for all parameters that 

were not pollutants of concern under the Bayou D'Inde TMDL, Subsegment 03090 I 

(Total Cyanide, Carbon Tetrachloride, I, 1-Dichloroethylene, Tetrachloroethylene, 

Hexachlorobenzene, and Hexachlorobutadiene ). Therefore, the final permit now 

includes interim and final schedules with revised requirements for these parameters. 

There was no change to the limitations/requirements for Total Nickel and I ,2-

Dichloroethane.

C. Outfall CO I • Sasol has requested a three year compliance schedule for new water 

quality based effluent limitations (Total Cyanide, Hexachlorobenzene, and 

Hexachlorobutadiene ). This request has been granted. The final permit now includes 

interim and final schedules with revised requirements for these parameters. 

D. Part II, Sections K, L, and M of the final permit have been updated per request of 

Sasol. 

E. Part I, footnote(*6) on Outfalls BOI and COl (Interim and Final) have been updated 

per request of Sasol. 

F. Part II, Section 0 (DMR Requirements) has been updated to include new language 

which allows for electronic DMR submittals. 

G. The STORET Codes for 1,2-Dichloroethane and Chloroethane have been changed 

to reflect "321 03" and "85811 ",respectively, based on the new tracking system used 

by the Permit Compliance Unit. 

VI. Permit Limit Rationale: 

The following section sets forth the principal facts and the significant factual, legal, 

methodological, and policy questions considered in preparing the draft permit. Also set forth 

are any calculations or other explanations of the derivation of specific effluent limitations 

and conditions, including a citation to the applicable effluent limitation guideline or 

performance standard provisions as required under LAC 33 :IX.2707 /40 CFR Part 122.44 and 

reasons why they are applicable or an explanation of how the alternate effluent limitations 

were developed. 

A. TECHNOLOGY-BASED VERSUS WATER QUALITY STANDARDS-BASED 

EFFLUENT LIMITATIONS AND CONDITIONS 

Following regulations promulgated at LAC 33:IX.2707.L.2.b/40 CFR Part 

122.44(1)(2)(ii), the draft permit limits are based on either technology-based effluent 

limits pursuant to LAC 33:1X.2707.A/40 CFR Part 122.44(a) or on State water 

quality standards and requirements pursuant to LAC 33:IX.2707.D/40 CFR Part 

122.44( d), whichever are more stringent. 

B. TECHNOLOGY-BASED EFFLUENT LIMITATIONS, CONDITIONS, AND 

MONITORING REQUIREMENTS 

Regulations promulgated at LAC 33:IX.2707.A/40 CFR Part 122.44(a) require 

technology-based effluent limitations to be placed in LPDES permits based on 

effluent limitations guidelines where applicable, on BP J (best professional judgment) 

in the absence of guidelines, or on a combination of the two. The following is a 

rationale for types of wastewaters. See outfall information descriptions for 

associated outfall(s) in Section VII. Regulations also require permits to establish 

monitoring requirements to yield data representative of the monitored activity [LAC

(*2) Water quality based effluent limitations due to the TMDL. 

Calculations and basis of permit limitations are found at Appendices A-1, B-1, and 

associated appendices of the Fact Sheet and Rationale dated December 9, 2008. See 

below for site-specific considerations. 

Site-Specific Technology and Water Quality Consideration(s) for Outfall 001 

(Interim Schedule) 

Flow - this requirement has been established in accordance with LAC 

33:IX.2707.1.l.b. and retained from the current LPDES permit effective on May 15, 

2002. The continuous monitoring frequency has also been retained. 

pH -this requirement has been established in accordance with LAC 33 :IX.lll3 .C. I. 

and retained from the current LPDES permit effective on May 15, 2002. The 

continuous monitoring frequency has also been retained. 

BODs and TSS - monthly average and daily maximum limitations have been 

established in accordance with OCPSF Guidelines under 40 CFR 414, Subparts F, 

G, and H with a process wastewater flow of 1.317312 MGD. Additionally, 

allocations have been granted for sanitary wastewater and utility wastewaters based 

on best professional judgment. Sanitary allocations are applied to a flow of 0.01944 

MGD and based on a 30 mg!L monthly average concentration and 45 mg/L daily 

maximum concentration for BODs and TSS. Utility wastewater allocations are 

applied to a flow of 1.21248 MGD and based on a 5 mg/L monthly average 

concentration and I 0 mg!L daily maximum concentration for BODs and a I 0 mg!L 

monthly average concentration and 20 mg/L daily maximum concentration for TSS. 

Sasol requested a monitoring frequency reduction for BODs and TSS from 2/week 

to 1/month in accordance with the USEP A Memorandum "Interim Guidance for 

Performance-Based Reductions of NPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualify for the requested 

reduction for BODs, the Department has determined that I /month sampling is not an 
Addendum to the Fact Sheet and Rationale for

LA0003336, AI No. 3271 

Page 9 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for BOD, has been reduced from 2/week to 

1/week. No reductions were granted for TSS due to an excursion reported in March 

2007. 

COD - monthly average and daily maximum limitations are based on a COD to 

BOD5 ratio of7: I and are applied as best available technology (BAT). The basis for 

these requirements has been retained from the current LPDES permit effective on 

May 15, 2002. Sasol requested a monitoring frequency reduction for COD from 

2/week to I /month in accordance with the USEP A Memorandum "Interim Guidance 

for Performance-Based Reductions ofNPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualify for the requested 

reduction for COD, the Department has determined that ]/month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for COD has been reduced from 2/week to 

!/week. 

Ammonia (as N)- mass limitations were calculated using the current outfall flow of 

2.549232 MGD and the BAT concentrations of2.27 mg/L monthly average and 4.88 

mg/L daily maximum, as established in the January 20, 1986 NPDES Fact Sheet and 

carried over in the March 18, 2002 Response to Comments Document that 

accompanied LPDES permit effective May 15, 2002. The resulting limitations were 

48 lbs/day monthly average and I 04 lbs/day daily maximum. However, the Upper 

Calcasieu Estuary TMDL, issued in the Federal Register on June 13, 2002 requires 

retention of previous permit limitations for Ammonia (as N), therefore, the 4Jlbs/day 

monthly average and 88 lbs/day daily maximum limitations were retained from the 

current LPDES permit, effective on May 15, 2002. Per request from Sasol, the 

monitoring frequency has been reduced from 1/week to 1/ 2 months in accordance 

with the USEPA Memorandum "Interim Guidance for Performance-Based 

Reductions ofNPDES Permit Monitoring Frequencies." 

Total Copper, Total Mercury, Benzo(a)anthracene, and Benzo(a)pyrene- loadings 

have been established at this outfall per the Upper Calcasieu Estuary TMDL, issued 

in the Federal Register on June 13, 2002. A monitoring frequency of I/ quarter has 

been established based on the sampling requirements established in the TMDL. 

Benzene, Carbon Tetrachloride, Chlorobenzene, Chloroethane, Chloroform, 1,1-

Dichloroethane, I ,2-Dichloroethane, Ethyl benzene, Methyl Chloride, Methylene 

Chloride, Toluene, I, I, 1-Trichloroethane, I, I ,2-Trichloroethane, and Vinyl Chloride 

- monthly average and daily maximum limitations have been established to ensure 

compliance with the OCPSF Guidelines under 40 CFR Part 414, Subparts F, G, H, 

and I. Per request from Sasol, the monitoring frequency has been reduced from 

I/ week to I I 2 months in accordance with the US EPA Memorandum "Interim 

Guidance for Performance-Based Reductions of NPDES Permit Monitoring 

Frequencies." 

Hexachlorobenzene - monthly average and daily maximum limitations have been 

established to ensure compliance the OCPSF Guidelines under 40 CFR Part 414,

Subparts F, G, H, and I. Additionally, water quality based effluent limitations were 

calculated using guidance procedures presented in the Permitting Guidance 

Document for Implementing Louisiana Surface Water Quality Standards, LDEQ, 

April 16,2008. Since this parameter was not identified as a pollutant of concern in 

Subsegment 030301, Sasol has been granted a three year compliance schedule in 

accordance with LAC 33 :IX.2713.A. This schedule will require Sasol to comply with 

the OCPSF technology based effluent limitations for the first three years of this 

permit to allow the permittee time to come into compliance with the new water 

quality based effluent limitations. The monitoring frequency has been increased from 

1/year to I! quarter due to an EPA, Region VI recommendation fo r quarterly 

monitoring (at a minimum) on all water quality based effluent limitation parameters.

(*I) The pH shall be within a range of 6.0- 9.0 Standard Units at all times subject

Paragraph H of the permit. 

(*2) Water quality based effluent limitations. 

Calculations and basis of permit limitations are found at Appendices A-1, B-1, and 

associated appendices of the Fact Sheet and Rationale dated December 9, 2008. See 

below for site-specific considerations. 

Site-Specific Technology and Water Quality Consideration(s) for Outfall 001 

(Final Schedule) 

Flow - this requirement has been established in accordance with LAC 

33:IX.2707.1. I. b. and retained from the current LPDES permit effective on May 15, 

2002. The continuous monitoring frequency has also been retained. 

pH -this requirement has been established in accordance with LAC 33:IX.lll3.C.l. 

and retained from the current LPDES permit effective on May 15, 2002. The 

continuous monitoring frequency has also been retained. 

BOD, and TSS - monthly average and daily maximum limitations have been 

established in accordance with OCPSF Guidelines under 40 CFR 414, Subparts F, 

G, and H with a process wastewater flow of 1.317312 MGD. Additionally, 

allocations have been granted for sanitary wastewater and utility wastewaters based 

on best professional judgment. Sanitary allocations are applied to a flow of 0.01944 

MGD and based on a 30 mg/L monthly average concentration and 45 mg!L daily 

maximum concentration for BOD5 and TSS. Utility wastewater allocations are 

applied to a flow of 1.21248 MGD and based on a 5 mg/L monthly average 

concentration and I 0 mg/L daily maximum concentration for BOD5 and a I 0 mg/L 

monthly average concentration and 20 mg/L daily maximum concentration for TSS. 

Sasol requested a monitoring frequency reduction for BOD5 and TSS from 2/week 

to 1/month in accordance with the USEP A Memorandum "Interim Guidance for 

Performance-Based Reductions ofNPDES Permit Monitoring Frequencies." This 
Addendum to the Fact Sheet and Rationale for 

Sasol North America, Inc., Lake Charles Chemical Complex 

LA0003336, AI No. 3271 

Page 16 

request has been partially granted. Although Sasol does qualify for the requested 

reduction for BOD,, the Department has determined that !/month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for BOD, has been reduced from 2/week to 

!/week. No reductions were granted for TSS due to an excursion reported in March 

2007. 

COD - monthly average and daily maximum limitations are based on a COD to 

BOD, ratio of7: I and are applied as best available technology (BAT). The basis for 

these requirements has been retained from the current LPDES permit effective on 

May 15, 2002. Sasol requested a monitoring frequency reduction for COD from 

2/week to I /month in accordance with the USEP A Memorandum "Interim Guidance 

for Performance-Based Reductions ofNPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualify for the requested 

reduction for COD, the Department has determined that 1/month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for COD has been reduced from 2/week to 

!/week. 

Ammonia (as N)- mass limitations were calculated using the current outfall flow of 

2.549232 MOD and the BAT concentrations of2.27 mg!L monthly average and 4.88 

mg/L daily maximum, as established in the January 20, 1986 NPDES Fact Sheet and 

carried over in the March 18, 2002 Response lf:l Comments Document that 

accompanied LPDES permit effective May 15, 2002. The resulting limitations were 

48 lbs/day monthly average and I 04 lbs/day daily maximum. However, the Upper 

Calcasieu Estuary TMDL, issued in the Federal Register on June 13, 2002 requires 

retention of previous permit limitations for Ammonia (as N), therefore, the 41lbs/day 

monthly average and 88 lbs/day daily maximum limitations were retained from the 

current LPDES permit, effective on May 15, 2002. Per request from Sasol, the 

monitoring frequency has been reduced from 1/week to 1/ 2 months in accordance 

with the USEPA Memorandum "Interim Guidance for Performance-Based 

Reductions ofNPDES Permit Monitoring Frequencies." 

Total Copper, Total Mercury, Benzo(a)anthracene, and Benzo(a)pyrene- loadings 

have been established at this outfall per the Upper Calcasieu Estuary TMDL, issued 

in the Federal Register on June 13, 2002. A monitoring frequency of !/quarter has 

been established based on the sampling requirements established in the TMDL.

compliance with the OCPSF Guidelines under 40 CFR Part 414, Subparts F, G, H, 

and I. Per request from Sasol, the monitoring frequency has been reduced from 

!/week to 1/ 2 months in accordance with the USEPA Memorandum "Interim

Hexachlorobenzene - monthly average and daily maximum limitations have been 

established to ensure compliance the OCPSF Guidelines under 40 CFR Part 414, 

Subparts F, G, H, and I. Additionally, water quality based effluent limitations were 

established using guidance procedures presented in the Permitting Guidance 

Document for Implementing Louisiana Surface Water Oualitv Standards, LDEQ, 

April 16, 2008. The monitoring frequency has been increased from !/year to 

!/quarter due to an EPA, Region VI recommendation for quarterly monitoring (at a 

minimum) on all water quality based effluent limitations.

Site-Specific Technology and Water Ouality Consideration(s) for Outfall 

BOlflnterim Schedule) 

This outfall is proposed for use on an emergency basis only during pump failure or 

maintenance of the discharge line and will no/to be used on a permanent basis 

without receiving a permit modification to include additional requirements. 

Flow - this requirement has been established in accordance with LAC 

33 :IX.2707.l.l.b. and retained from the current LPDES permit effective on May 15, 

2002. The continuous monitoring frequency has also been retained.

pH- this requirement has been established in accordance with LAC 33 :IX.lll3 .C.l. 

and retained from the current LPDES permit effective on May 15, 2002. The 

continuous monitoring frequency has also been retained. 

BOD, and TSS - monthly average and daily maximum limitations have been 

established in accordance with OCPSF Guidelines under 40 CFR 414, Subparts F, 

G, and H with a process wastewater flow of 1.317312 MGD. Additionally, 

allocations have been granted for sanitary wastewater and utility wastewaters based 

on best professional judgment. Sanitary allocations are applied to a flow of 0.01944 

MGD and based on a 30 mg/L monthly average concentration and 45 mg/L daily 

maximum concentration for BOD, and TSS. Utility wastewater allocations are 

applied to a flow of 1.21248 MGD and based on a 5 mg/L monthly average 

concentration and I 0 mg/L daily maximum concentration for BOD, and a I 0 mg/L 

monthly average concentration and 20 mg/L daily maximum concentration for TSS. 

Sasol requested a monitoring frequency reduction for BOD, and TSS from 2/week 

to !/month in accordance with the USEPA Memorandum "Interim Guidance for 

Performance-Based Reductions ofNPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualify for the requested 

reduction for BOD,, the Department has determined that !/month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for BOD, has been reduced from 2/week to 

!/week. No reductions were granted for TSS due to an excursion reported in March 

2007. 

COD - monthly average and daily maximum limitations are based on a COD to 

BOD, ratio of 7: I and are applied as best available technology (BAT). The basis of 

this requirement has been retained from the current LPDES permit effective on May 

15, 2002. Sasol· requested a monitoring frequency reduction for COD from 2/week 

to !/month in accordance with the USEPA Memorandum "Interim Guidance for 

Performance-Based Reductions of NPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualify for the requested 

reduction for COD, the Department has determined that !/month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for COD has been reduced from 2/week to 

!/week. 

Ammonia (as N)- mass limitations were calculated using the current outfall flow of 

2.549232 MGD and the BAT concentrations of 2.27 mg/L for monthly average and 

4.88 mg/L for the daily maximum, as established in the January 20, 1986 NPDES 

Fact Sheet and carried over in the March 18,2002 Response to Comments Document 

that accompanied LPDES permit effective May 15, 2002. The resulting limitations 

were 48 lbs/day monthly average and I 04 lbs/day daily maximum. However, this 

Office has determined that it is more appropriate to apply the TMDL requirements 

for Ammonia (as N) as established at Subsegment 030301 and the current LPDES 

permit, effective on May 15, 2002. Therefore, the monthly average limitation of 41 

lbs/day and the daily maximum limitation of88lbs/day have been established based 

on best professional judgment. Per request from Sasol, the monitoring frequency has

Page 24 

been reduced from ]/week to 11 2 months in accordance with the USEPA 

Memorandum "Interim Guidance for Performance-Based Reductions of NPDES 

Permit Monitoring Frequencies." 

Total Copper, Total Mercury, Benzo(a)anthracene, and Benzo(a)pyrene - these 

parameters were identified as pollutants of concern in the Calcasieu TMDL for 

Subsegment 030306, issued in the Federal Register on June 13, 2002. However, the 

TMDL failed to establish any requirements for these parameters at this alternate 

outfall location. Therefore, to ensure protection of the receiving waterbody, this 

Office has determined that it is appropriate to apply the loadings established for 

Subsegment 030301 at the alternate outfall location based on best professional 

judgment. A monitoring frequency of ]/quarter has also been established based on 

best professional judgment using the sampling frequency requirements suggested in 

the Calcasieu TMDL for Subsegment 030301. 

Total Zinc, Total Calcium, 2-Methylnapthalene, and Dibenzo(a,h)anthracene- these 

parameters were identified as pollutants of concern in the Calcasieu TMDL for 

Subsegment 030306, issued in the Federal Register on June 13, 2002. However, the 

TMDL failed to establish any requirements for these parameters at this alternate 

outfall location. Therefore, to ensure protection of the receiving waterbody, monitor 

and report only requirements have been established based on best professional 

judgment. A monitoring frequency of II quarter has been established due to an EPA, 

Region VI recommendation for quarterly monitoring (at a minimum) on all water 

quality based effluent requirements. 

Total Nickel - this parameter was identified as a pollutant of concern in the 

Calcasieu TMDL for Subsegment 030306, issued in the Federal Register on June 13, 

2002. However, the TMDL failed to establish any requirements for this parameter at 

this alternate outfall location. Therefore, analytical data (0.3292lbs/day)provided in 

the addendum to the LPDES permit application dated December 19, 2006 was 

screened against current water quality standards using guidance procedures presented 

in the Permitting Guidance Document for Implementing Louisiana Surface Water 

Oualitv Standards, LDEQ, April 16, 2008. The value for Total Nickel exceeded 

water quality standards and required LDEQ to establish water quality based effluent 

limitations. LDEQ has determined that it is appropriate to establish the water quality 

based effluent limitations effective upon issuance of the permit. This approach is 

consistent with implementation of the TMDL and ensures protection of the receiving 

waterbody. 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) of the CWA. Because the TMDLs for the Calcasieu River Basin were 

finalized in 2002, implementation of the TMDLs into LPDES permits IIl1.lSt be 

accomplished by 2008. A monitoring frequency of II quarter has been established due 

to an EPA, Region VI recommendation for quarterly monitoring (at a minimum) on 

all water quality based effluent requirements.

I ,2-Dichloroethane- this parameter was identified as a pollutant of concern in the 

Calcasieu TMDL for Subsegment 030306, issued in the Federal Register on June 13, 

2002. However, the TMDL failed to establish any requirements for this parameter at 

the alternate outfall location. Therefore, OCPSF technology based effluent limitations 

were screened against current water quality standards using guidance procedures 

presented in the Permitting Guidance Document for Implementing Louisiana Surface 

Water Oualitv Standards, LDEQ, April 16, 2008. The technology based effluent 

limitations for I ,2-Dichloroethane exceeded water quality standards and required 

LDEQ to establish water quality based effluent limitations. LDEQ has determined 

that it is appropriate to establish the water quality based effluent limitations effective 

upon issuance of the permit. This approach is consistent with implementation of the 

TMDL and ensures protection of the receiving waterbody. 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) of the CW A. Because the TMDLs 

for the Calcasieu River Basin were finalized in 2002, implementation of the TMDLs 

into LPDES permits must be accomplished by 2008. Per request from Sasol, the 

monitoring frequency has been reduced from !/week to 1/ 2 months in accordance 

with the USEPA Memorandum "Interim Guidance for Performance-Based 

Reductions ofNPDES Permit Monitoring Frequencies. 

Carbon Tetrachloride - monthly average and daily maximum limitations were 

calculated in accordance with the OCPSF Guidelines under 40 CFR Part 414, 

Subparts F, G, H, and I. Additionally, water quality based effluent limitations were 

calculated using guidance procedures presented in the Permitting Guidance 

Document for Implementing Louisiana Surface Water Quality Standards, LDEQ, 

April 16, 2008. Since this parameter was not identified as a pollutant of concern in 

the Calcasieu TMDL for Subsegment 030306, Sasol has been granted a three year 

compliance schedule in accordance with LAC 33 :IX.2713.A. This schedule requires 

Sasol to comply with the OCPSF technology based effluent limitations for the first 

three years of this permit to allow time to come into compliance with the new water 

quality based effluent limitations. Per request from Sasol, the monitoring frequency 

has been reduced from ]/week to 1/ 2 months in accordance with the USEPA 

Memorandum "Interim Guidance for Performance-Based Reductions of NPDES 

Permit Monitoring Frequencies." 

Phenol, Anthracene, Chrysene, Fluoranthene, Pyrene, and Phenanthrene - these 

parameters have been identified as pollutants of concern in the Calcasieu TMDL. 

However, the TMDL failed to establish any requirements for these parameters at this 

alternate outfall location. Therefore, to ensure protection of the receiving waterbody 

monthly average and daily maximum limitations were calculated in accordance with 

current water quality standards and the OCPSF Guidelines under 40 CFR Part 414, 

Subparts F, G, H, and I. The monitoring frequencies have been increased from !/year

BOD, and TSS - monthly average and daily maximum limitations have been 

established in accordance with OCPSF Guidelines under 40 CFR 414, Subparts F, 

G, and H with a process wastewater flow of 1.317312 MGD. Additionally, 

allocations have been granted for sanitary wastewater and utility wastewaters based 

on best professional judgment. Sanitary allocations are applied to a flow of 0.01944 

MGD and based on a 30 mg/L monthly average concentration and 45 mg/L daily 

maximum concentration for BOD, and TSS. Utility wastewater allocations are 

applied to a flow of 1.21248 MGD and based on a 5 mg/L monthly average

concentration and I 0 mg/L daily maximum concentration for BODs and a I 0 mg/L 

monthly average concentration and 20 mg/L daily maximum concentration for TSS. 

Sasol requested a monitoring frequency reduction for BODs and TSS from 2/week 

to !/month in accordance with the USEPA Memorandum "Interim Guidance for 

Performance-Based Reductions ofNPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualifY for the requested 

reduction for BODs, the Department has determined that 1/month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for BODs has been reduced from 2/week to 

!/week. No reductions were granted for TSS due to an excursion reported in March 

2007. 

COD - monthly average and daily maximum limitations are based on a COD to 

BODs ratio of 7: I and are applied as best available technology (BAT). The basis of 

this requirement has been retained from the current LPDES permit effective on May 

15, 2002. Sasol requested a monitoring frequency reduction for COD from 2/week 

to 1/month in accordance with the USEPA Memorandum "Interim Guidance for 

Performance-Based Reductions of NPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualifY for the requested 

reduction for COD, the Department has determined that I /month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for COD has been reduced from 2/week to 

1/week. 

Arrunonia (as N)- mass limitations were calculated using the current outfall flow of 

2.549232 MGD and the BAT concentrations of2.27 mg/L for monthly average and 

4.88 mg/L for the daily maximum, as established in the January 20, 1986 NPDES 

Fact Sheet and carried over in the March 18,2002 Response to Comments Document 

that accompanied LPDES permit effective May 15, 2002. The resulting limitations 

were 48 lbs/day monthly average and I 04 lbs/day daily maximum. However, this 

Office has determined that it is more appropriate to apply the TMDL requirements 

for Arrunonia (as N) as established at Subsegment 030301 and the current LPDES 

permit, effective on May 15, 2002. Therefore, the monthly average limitation of 41 

lbs/day and the daily maximum limitation of 88 lbs/day has been established based 

on best professional judgment. Per request from Sasol, the monitoring frequency has 

been reduced from 1/week to 1/ 2 months in accordance with the USEPA 

Memorandum "Interim Guidance for Performance-Based Reductions of NPDES 

Permit Monitoring Frequencies." 

Total Copper, Total Mercury, Benzo(a)anthracene, and Benzo(a)pyrene - these 

parameters were identified as pollutants of concern in the Calcasieu TMDL for 

Subsegment 030306, issued in the Federal Register on June 13, 2002. However, the 

TMDL failed to establish any requirements for these parameters at this alternate 

outfall location. Therefore, to ensure protection of the receiving waterbody, this 

Office has determined that it is appropriate to apply the loadings established for 

Subsegment 03030 I at the alternate outfall location based on best professional 

judgment. A monitoring frequency of I /quarter has also been established based on

parameters were identified as pollutants of concern in the Calcasieu TMDL for 

Subsegment 030306, issued in the Federal Register on June 13, 2002. However, the 

TMDL failed to establish any requirements for these parameters at this alternate 

outfall location. Therefore, to ensure protection of the receiving waterbody, monitor 

and report only requirements have been established based on best professional 

judgment. A monitoring frequency of !/quarter has been established due to an EPA, 

Region VI recommendation for quarterly monitoring (at a minimum) on all water 

quality based effluent requirements. 

Total Nickel -this parameter was identified as a pollutant of concern in the Calcasieu 

TMDL for Subsegment 030306, issued in the Federal Register on June 13, 2002. 

However, the TMDL failed to establish any requirements for this parameter at the 

alternate outfall location. Therefore, analytical data (0.3292lbs/day) provided in the

against current water quality standards using guidance procedures presented in the 

Permitting Guidance Document for Implementing Louisiana Surface Water Quality 

Standards, LDEQ, Aprill6, 2008. The value for Total Nickel exceeded water quality 

standards and required LDEQ to establish water quality based effluent limitations.

Sasol requested a monitoring frequency reduction for BODs and TSS from 2/week 

to !/month in accordance with the USEPA Memorandum "Interim Guidance for 

Performance-Based Reductions of NPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualify for the requested 

reduction for BODs, the Department has determined that I /month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for BODs has been reduced from 2/week to 

I /week. No reductions were granted for TSS due to an excursion reported in March 

2007. 

COD - monthly average and daily maximum limitations are based on a COD to 

BODs ratio of 7: I and are applied as best available technology (BAT). The basis of 

this requirement has been retained from the current LPDES permit effective on May 

15, 2002. Sasol requested a monitoring frequency reduction for COD from 2/week 

to 1/month in accordance with the USEPA Memorandum "Interim Guidance for 

Performance-Based Reductions of NPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualify for the requested 

reduction for COD, the Department has determined that !/month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for COD has been reduced from 2/week to 

1/week. 

Ammonia (as N)- mass limitations were calculated using the current outfall flow of 

2.549232 MGD and the BAT concentrations of2.27 mg!L for monthly average and 

4.88 mg/L for the daily maximum, as established in the January 20, 1986 NPDES 

Fact Sheet and carried over in the March 18, 2002 Response to Comments Document 

that accompanied LPDES permit effective May 15, 2002. The resulting limitations 

were 48 lbs/day monthly average and I 04 lbs/day daily maximum. However, the 

Upper Calcasieu Estuary TMDL, issued in the Federal Register on June 13, 2002 

requires retention of previous permit limitations for Ammonia (as N), therefore, the 

41 lbs/day monthly average and 88 lbs/day daily maximum limitations have been 

retained from the current LPDES permit, effective on May 15, 2002. Per request from 

Sasol, the monitoring frequency has been reduced from !/week to 1/ 2 months in 

accordance with the USEPA Memorandum "Interim Guidance for PerformanceBased Reductions ofNPDES Permit Monitoring Frequencies." 

Total Copper, Total Mercury, Benzo(a)anthracene, and Benzo(a)pyrene- loadings 

have been established at this outfall per the Upper Calcasieu Estuary TMDL, issued 

in the Federal Register on June 13, 2002. A monitoring frequency of I/ quarter has 

been established based on the sampling requirements established in the TMDL. 

Total Cyanide - Analytical data (0.093 lbs/day) provided in the addendum to the 

LPDES permit application dated December 19, 2006 was screened against current 

water quality standards using guidance procedures presented in the Permitting 

Guidance Document for Implementing Louisiana Surface Water Ouality Standards,

accordance with LAC 33:IX.2713.A. This schedule will require Sasol to comply with 

monitor and report only requirements for the first three years of this permit to allow 

time to come into compliance with the new water quality based effluent limitations. 

A monitoring frequency of !/quarter has been established due to an EPA, Region VI 

recommendation for quarterly monitoring (at a minimum) on all water quality based 

effluent requirements.

!/week to 1/ 2 months in accordance with the USEPA Memorandum "Interim 

Guidance for Performance-Based Reductions of NPDES Permit Monitoring 

Frequencies." 

Hexachlorobenzene and Hexachlorobutadiene- monthly average and daily maximum 

limitations were calculated in accordance with the OCPSF Guidelines under 40 CFR 

Part 414, Subparts F, G, H, and I. Additionally, water quality based effluent 

limitations were calculated using guidance procedures presented in the Permitting 

Guidance Document for Implementing Louisiana Surface Water Oualitv Standards, 

LDEQ, April 16, 2008. Since these parameters were not identified as pollutants of 

concern in the Calcasieu TMDL for Subsegment 030301, Sasol has been granted a 

three year compliance schedule in accordance with LAC 33:1X.2713.A. This 

schedule requires Sasol to comply with the OCPSF technology based effluent 

limitations for the first three years of this permit to allow time to come into 

compliance with the new water quality based effluent limitations. The monitoring 

frequencies have been increased from 1/yearto !/quarter due to an EPA, Region VI 

recommendation for quarterly monitoring (at a minimum) on all water quality based 

effluent limitations.

associated appendices of the Fact Sheet and Rationale dated December 9, 2008. See 

below for site-specific considerations. 

Site-Specific Technology and Water Quality Consideration(s) for Outfall COl 

(Final Schedule) 

This outfall is proposed for use on an emergency basis only in the event that the 

diffuser is taken out of service or during the maintenance oft he diffuser and will not 

to be used on a permanent basis without receiving a permit modification to include 

additional requirements. 

Flow - this requirement has been established in accordance with LAC 

33:IX.2707.l.l.b. and retained from the current LPDES permit effective on May 15, 

2002. The continuous monitoring frequency has also been retained. 

pH- this requirement has been established in accordance with LAC 33:IX.III3.C.I. 

and retained from the current LPDES permit effective on May 15, 2002. The 

continuous monitoring frequency has also been retained. 

BODs and TSS - monthly average and daily maximum limitations have been 

established in accordance with OCPSF Guidelines under 40 CFR 414, Subparts F, 

G, and H with a process wastewater flow of 1.317312 MGD. Additionally, 

allocations have been granted for sanitary wastewater and utility wastewaters based 

on best professional judgment. Sanitary allocations are applied to a flow of0.01944 

MGD and based on a 30 mg/L monthly average concentration and 45 mg/L daily 

maximum concentration for BODs and TSS. Utility wastewater allocations are 

applied to a flow of 1.21248 MGD and based on a 5 mg!L monthly average 

concentration and I 0 mg!L daily maximum concentration for BODs and a I 0 mg!L 

monthly average concentration and 20 mg/L daily maximum concentration for TSS. 

Sasol requested a monitoring frequency reduction for BODs and TSS from 2/week 

to !/month in accordance with the USEPA Memorandum "Interim Guidance for 

Performance-Based Reductions ofNPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualify for the requested 

reduction for BODs, the Department has determined that 1/month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for BODs has been reduced from 2/week to 

!/week. No reductions were granted for TSS due to an excursion reported in March 

2007. 

COD - monthly average and daily maximum limitations are based on a COD to 

BODs ratio of 7: I and are applied as best available technology (BAT). The basis of 

this requirement has been retained from the current LPDES permit effective on May 

15, 2002. Sasol requested a monitoring frequency reduction for COD from 2/week 

to I /month in accordance with the USEP A Memorandum "Interim Guidance for 

Performance-Based Reductions ofNPDES Permit Monitoring Frequencies." This 

request has been partially granted. Although Sasol does qualify for the requested 
Addendum to the Fact Sheet and Rationale for 

Sasol North America, Inc., Lake Charles Chemical Complex 

LA0003336, AI No. 3271 

Page 50 

reduction for COD, the Department has determined that 1/month sampling is not an 

adequate frequency for conventional and non-conventional parameters for major 

facilities. Therefore, the frequency for COD has been reduced from 2/week to 

!/week. 

Ammonia (as N)- mass limitations were calculated using the current outfall flow of 

2.549232 MOD and the BAT concentrations of2.27 mg/L for monthly average and 

4.88 mg/L for the daily maximum, as established in the January 20, 1986 NPDES 

Fact Sheet and carried over in the March 18, 2002 Response to Comments Document 

that accompanied LPDES permit effective May 15, 2002. The resulting limitations 

were 48 lbs/day monthly average and I 04 lbs/day daily maximum. However, the 

Upper Calcasieu Estuary TMDL, issued in the Federal Register on June 13, 2002 

requires retention of previous permit limitations for Ammonia (as N), therefore, the 

41 lbs/day monthly average and 88 lbs/day daily maximum limitations have been 

retained from the current LPDES permit, effective on May 15,2002. Per request from 

Sasol, the monitoring frequency has been reduced from I /week to I I 2 months in 

accordance with the USEPA Memorandum "Interim Guidance for PerformanceBased Reductions ofNPDES Permit Monitoring Frequencies." 

Total Copper, Total Mercury, Benzo(a)anthracene, and Benzo(a)pyrene- loadings 

have been established at this outfall per the Upper Calcasieu Estuary TMDL, issued 

in the Federal Register on June 13, 2002. A monitoring frequency of I! quarter has 

been established based on the sampling requirements established in the TMDL. 

Total Cyanide - Analytical data (0.093 lbs/day) provided in the addendum to the 

LPDES permit application dated December 19, 2006 was screened against current 

water quality standards using guidance procedures presented in the Permitting 

Guidance Document for Implementing Louisiana Surface Water Ouality Standards, 

LDEQ, Aprill6, 2008. The value for Total Cyanide exceeded water quality standards 

and required LDEQ to establish water quality based effluent limitations. A 

monitoring frequency of I /quarter has been established due to an EPA, Region VI 

recommendation for quarterly monitoring (at a minimum) on all water quality based 

effluent requirements.
