SECTION A. APPLICABILITY

Facilities covered by this general permit are those discharging treated sanitary wastewater and/or other accepted 

wastewater types in quantities less than 5,000 GPD maximum expected flow as calculated using the sewage loading guidelines in 

the state sanitary code or from an alternative approved data source and which are required to meet a secondary level of treatment. 

“Accepted wastewater types” include those wastewaters with effluent characteristics which are not significantly different from 

sanitary wastewaters and which may be successfully treated by biological means to meet effluent limitations. Facilities covered 

include, but are not limited to, residential subdivisions, trailer parks, on-site residential laundry facilities, coin operated

Laundromats, restaurants, schools, shopping centers, office buildings, and publicly owned treatment works. 

All persons operating a source or conducting an activity that results in a treated sanitary wastewater discharge as described 

above are eligible for coverage under this general permit and will become permittees authorized to discharge upon written 

notification by this Office of coverage under this general permit. Notice of intent (NOI) to be covered under this general permit 

should be made using form WPS-G which may be obtained by calling (225) 219-3181 or on the internet at 

http://www.deq.louisiana.gov/portal/Portals/0/permits/lpdes/wps-g.pdf. Existing dischargers eligible for this permit must 

submit a NOI within thirty (30) days of the effective date of this permit. Proposed facilities desiring coverage under this permit 

must submit a NOI at least thirty (30) days prior to commencement of discharge. Any permittee covered by an individual permit 

may request that the individual permit be canceled if the permitted source or activity is also eligible for coverage by this general 

permit. Upon written acceptance of that request by this Office, the permittee will be covered by this general permit. Existing 

dischargers currently covered under the previous Class I Sanitary Discharge General Permit shall automatically be covered under

this general permit, provided they continue to meet all applicability requirements. 

This general permit shall not apply to: 

1. discharges other than those described above; 

2. facilities which do not conform with the regulations set forth in the Louisiana Sanitary Code; 

3. facilities which receive unacceptable wastewater types from industrial and/or other sources; and 

 4. facilities which have been assigned limitations in the Louisiana Water Quality Management Plan or an approved 

Waste Load Allocation (from a previous study or from the current updates from the Total Maximum Daily 

Loads) that are different from those in this permit. 

5. sanitary discharges at operations classed as new sources or new dischargers, if the discharge will cause or 

contribute to the violation of water quality standards (LAC 33:IX.2317.A.9). 

6. facilities proposing to discharge into a waterbody designated as Outstanding Natural Resource Waters, as defined 

in LAC 33:IX.1123.Table 3, if it will cause degradation of these waters. As per LAC 33:IX.1119.C.4, 

Degradation is defined as a statistically significant difference at the 90 percent confidence interval from existing 

physical, chemical, and biological conditions. It will be the applicant’s responsibility to provide data to the 

Water Permit Division to show that its facility will not cause degradation to Outstanding Natural Resource 

Waters as defined above. 

SECTION B. EFFLUENT LIMITATIONS

The limitations listed below shall apply to each outfall at the facility. Please see Appendix A of this permit for the Outfall

description and applicable schedules that shall apply to each particular outfall.

OTHER REQUIREMENTS 

The Permittee must comply with all applicable provisions of the Louisiana Water Quality Regulations 

including all of the standard conditions found in LAC 33:IX.2701. This Office has established the 

following definitions and requirements in accordance with those regulations. The definition of other terms 

may be found in the Louisiana Water Quality Regulations (LAC 33:IX.2313). 

SECTION A. DEFINITIONS

1. Act: means Act 449 of the 1979 Louisiana Legislature which established Section 2001, et seq. of 

Title 30 of the Louisiana Revised Statutes of 1950 and any subsequent amendment to these 

Sections. 

2. Biochemical oxygen demand (BOD5): means the amount of oxygen required by bacteria during 

 the decay of organic and nitrogenous material in sanitary sewage. 

3. Daily Discharge: means the discharge of a pollutant measured during a calendar day or any 24-

hour period that reasonably represents the calendar day for purposes of sampling. For pollutants 

with limitations expressed in terms of mass, the “daily discharge” is calculated as the total mass of 

the pollutant discharged over the sampling day. For pollutants with limitations expressed in other 

units of measurements, the “daily discharge” is calculated as the average measurement of the 

pollutant over the sampling day. “Daily discharge” determination of concentration made using a 

composite sample shall be the concentration of the composite sample. When grab samples are 

used, the “daily discharge” determination of concentration shall be the arithmetic average 

(weighted by flow value) of all samples collected during that sampling day. 

4. Daily Maximum: discharge limitation means the highest allowable “daily discharge” during the 

calendar month. 

5. Monthly Average: other than for fecal coliform bacteria, is the highest allowable arithmetic mean 

of the “daily discharges” over a calendar month, calculated as the sum of all “daily discharges” 

measured during a calendar month divided by the number of “daily discharges” measured during 

that month. The monthly average for fecal coliform bacteria is the geometric mean of the “daily 

discharges” over a calendar month. 

6. Weekly Average: other than for fecal coliform bacteria, is the highest allowable arithmetic mean of 

the “daily discharges” over a calendar week, calculated as the sum of all “daily discharges” 

measured during a calendar week divided by the number of “daily discharges” measured during 

that week. The weekly average for fecal coliform bacteria is the geometric mean of the “daily 

discharges” over a calendar week. 

7. Facility: means a pollution source, or any public or private property or site and all contiguous land 

and structures, other appurtenances and improvements, where any activity is conducted which 

discharges or may result in the discharge of pollutants into waters of the State.

of warm-blooded animals. 

9. Maximum Expected Flow: means the rate of wastewater flow expected upon the completion of the planned 

facility or activity. 

10. mg/L: means milligrams per liter; it is essentially equivalent to parts per million in dilute aqueous solutions. 

11. Office: means the Office of Environmental Services within the Department of Environmental Quality. 

12. Sanitary wastewater: means treated or untreated wastewaters which contain human metabolic and domestic 

wastes. 

 

13. Standard Methods: means Standard Methods for the Examination of Water and Wastewater, American

OTHER REQUIREMENTS (cont.) 

SECTION C. COVERAGE UNDER SUBSEQUENT PERMITS

Should this permit expire before it is reissued, this Office will administratively extend the permit to discharge to 

current permittees until such time that a new general permit is issued. Instructions for obtaining coverage under the 

reissued permit will be included in that permit. 

SECTION D. TERMINATION OF AUTHORIZATION TO DISCHARGE

This Office reserves the right to revoke the authorization to discharge in accordance with this general permit as it 

applies to any person and/or require such person to apply for and obtain an individual permit if: 

1. the covered source or activity is a significant contributor of pollution or creates other environmental 

problems; 

2. the permittee is not in compliance with the terms and conditions of this general permit; 

3. conditions or standards have changed so that the source or activity no longer qualifies for this general 

permit; or 

4. the discharge limitations contained in this permit are not in accordance with the Louisiana Water Quality 

Management Plan. 

SECTION E. COMPLIANCE SCHEDULE

The permittee shall be in compliance with the effluent limitations and monitoring requirements specified herein on 

the date of authorization of coverage under this general permit. If a discharge is found to be in violation of specified 

limits, the permittee will be subject to enforcement action, including civil penalties, and may be required to obtain 

an individual permit. 

SECTION F. PROPERTY RIGHTS

Authorization to discharge pursuant to the conditions of this permit does not relieve the permittee of any liability for 

damages to state waters or private property. For discharges to private land, this permit does not relieve the 

permittee from obtaining approval from the landowner for appropriate easements and rights of way. 
PART II 

Page 4 of 11 

LAG530000; AI 97167

PER20060001

OTHER REQUIREMENTS (cont.) 

SECTION G. REMOVED SUBSTANCES

Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of wastewaters 

shall be properly disposed of in compliance with applicable state laws, regulations and permit requirements and in a 

manner such as to prevent any pollutant from such materials from entering the waters of the State. The permittee 

may need to contact the Water Permits Division of the Office of Environmental Services for information on 

regulations and permits to dispose of this material. 

SECTION H. SANITARY DISCHARGE

The Department of Environmental Quality reserves the right to impose more stringent discharge limitations and/or 

additional restrictions in the future to maintain water quality integrity and the designated uses of the receiving water 

bodies based upon water quality studies. These studies may indicate the need for more advanced wastewater 

treatment. Studies of similar discharges and receiving water bodies have resulted in monthly average effluent 

limitations of 5 mg/L CBOD5 and 2 mg/L NH3-N. Therefore, prior to upgrading or expanding any permitted 

sewage treatment method at the 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. 

Future water quality studies may indicate potential toxicity from the presence of residual chlorine in the treatment 

facility's effluent. Therefore, the permittee is hereby advised that a future Total Residual Chlorine Limitation may 

be required if chlorine is used as a method of disinfection. In many cases, this becomes a NO MEASURABLE

Total Residual Chlorine Limitation. If such a limitation were imposed, the permittee would be required to apply for 

an individual permit. 

SECTION I. OTHER DISCHARGES

This permit does not in any way authorize the permittee to discharge a pollutant not listed or quantified in the notice 

of intent or as otherwise authorized in the permit. 

Any runoff leaving the site, other than the permitted outfalls, exceeding 50 mg/l Total Organic Carbon 

(TOC), 15 mg/l Oil and Grease, or having a pH less than 6.0 or greater than 9.0 standard units shall be a 

violation of this permit. 
PART II

LAG530000; AI 97167

PER20060001

OTHER REQUIREMENTS (cont.) 

SECTION J. INTERIM EFFLUENT LIMITATIONS

The interim limitations found in the various schedules are intended to provide facilities with a reasonable amount of 

time in which to achieve compliance with the final effluent limitations. Under no circumstances will an eligible 

facility be allowed more than three years from the date of authorization of coverage under this general 

permit to attain compliance with the final effluent limitations. Facilities currently meeting the Final Effluent 

Limitations contained in this permit shall be required to continue to meet the Final Effluent Limitations 

unless otherwise instructed by this Office.

If an interim schedule is granted for a schedule in this permit, you are required to submit to this Office 

annual progress reports on the status of improvements at your facility. The first of these annual reports must 

be received no later than six (6) months from the original date of notification of coverage under this general 

permit. Subsequent reports shall be submitted at one year intervals.

In the event that this general permit expires before a given eligible facility has completed its interim period, 

provisions will be made upon the renewal of this general permit to allow such facilities time, not to exceed a total of 

three years from the original authority of coverage, to achieve compliance with the final effluent limitations.

 

SECTION K. STATE WATER QUALITY STANDARDS

LAC 33:IX.1113 describes numerical and general criteria that apply to all discharges into waters of the State. Criteria are 

elements of the water quality which set limitations on the permissible amounts of a substance or other characteristics of 

state waters. The General Criteria, as described in the Louisiana Administrative Code, limit discharges to maintain 

aesthetics, color, turbidity, the biological and aquatic community integrity, and many other elements in the receiving 

water body. Any noncompliance with the General or Numerical Criteria is not authorized under this permit. 

To comply with the requirements of LAC 33:IX.2317.A.9, this permit does not authorize a sanitary discharge at an 

operation which is classed as a new source or new discharge, as defined at LAC 33:IX.2313, if the discharge will cause or 

contribute to the violation of water quality standards. As with other LPDES general permits issued by LDEQ, an 

extensive eligibility review, based on the specialty NOI plus any additional clarifying information, including a site visit if 

needed, is required before authorization under the permit can be granted. Proposed discharges to receiving streams which 

are listed on the state’s 303(d) list will be evaluated, based on the extensive information which must be provided in the 

application form to determine their potential to cause or contribute to a violation of water quality standards. Evaluations 

of proposed discharge characteristics including volume, frequency, and method of release, distance from receiving 

stream, receiving stream hydrology, plus any relevant factors, will be completed. New source or new sanitary discharges 

determined to have reasonable potential to cause or contribute to the violation of water quality standards will not be 

approved, unless the reasonable potential is removed by applying one or more of the additional schedule allowed for in 

this permit. Documentation to support the permitting determination will be included in the statement of basis which must 

be prepared prior to the authorization of any discharge under this permit.

SECTION L. PERMIT REOPENER CLAUSE

This permit may be modified, revoked and reissued, or terminated for cause in accordance with LAC 33:IX.2903, 

2907, and 6509. The filing of a request for a permit modification, revocation and reissuance, or termination, or a 

notification of planned changes or anticipated noncompliance, does not stay any permit condition. This Office 

reserves the right to reopen and modify this permit to conform to those standards necessary to maintain the water 

quality in order to support uses of the receiving water bodies. This Office reserves the right to remove a facility on 

a 303(d) listed stream/segment from coverage or require an application if a final TMDL requires more stringent 

conditions for a covered facility. 

SECTION M. PERMIT CANCELLATION REQUIREMENTS

Should the permittee wish to cease the discharge activity and cancel this general permit, written notification must be 

forwarded to this Office. This notification must contain at a minimum the company name, facility name, general 

permit number, and description of the change in activities prompting the permittee’s request for cancellation. A 

LPDES Request for Termination form can also be used. This form (form RFT) is located on the LDEQ website at 

www.deq.louisiana.gov. 

SECTION N. MONITORING AND REPORTING REQUIREMENTS

1. All sampling and testing shall be conducted in accordance with 40 CFR Part 136. 

2. Samples shall be taken at the point of discharge from the treatment unit and prior to mixing with the 

receiving water. 

3. Provisions must be made during the installation of the treatment unit for obtaining a proper sample. 

4. Proper sampling techniques shall be used to ensure that analytical results are representative of pollutants in 

the discharge. 

5. The permittee shall at all times properly operate and maintain the facilities used to achieve compliance with 

the conditions of this permit. 

6. 24-hour Oral Reporting: Daily Maximum Limitation Violations

SECTION B. PROPER OPERATION AND MAINTENANCE

1. Need to Halt or Reduce not a Defense

It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt 

or reduce the permitted activity in order to maintain compliance with the conditions of this permit. 

2. Duty to Mitigate

The permittee shall take all reasonable steps to minimize or prevent any discharge in violation of this permit 

which has a reasonable likelihood of adversely affecting human health or the environment. The permittee 

shall also take all reasonable steps to minimize or correct any adverse impact on the environment resulting 

from noncompliance with the permit, including such accelerated or additional monitoring as necessary to 

determine the nature and impact of the noncomplying discharge. 

3. Proper Operation and Maintenance

a. The permittee shall at all times properly operate and maintain all facilities and systems of treatment and 

control (and related appurtenances) which are installed or used by the permittee to achieve compliance 

with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory

4. Bypass of Treatment Facilities

a. Bypass. 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 if 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. 

(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in 

LAC 33:IX.2701.L.6, (24-hour notice) and Section D.6.e. of these standard conditions. 

d. Prohibition of 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 

effects, if the state administrative authority determines that it will meet the three conditions listed in 

Section B.4.d(1) of these standard conditions. 

5. Upset Conditions 

a. Upset. An exceptional incident in which there is unintentional and temporary noncompliance with 

technology based permit effluent limitations because of factors beyond the reasonable control of the 

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.5.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 necessary 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:IX.2701.L.6.b.ii. and Section 

D.6.e.(2) of these standard conditions; and 
REVISED 4/25/07 Page 5 of 17

form_7027_r05 

4/25/07 

(4) The permittee complied with any remedial measures required by Section B.2 of these standard 

conditions. 

d. Burden of proof. In any enforcement proceeding, the permittee seeking to establish the occurrence of 

an upset has the burden of proof. 

6. Removed Substances

Solids, sewage sludges, filter backwash, or other pollutants removed in the course of treatment or 

wastewater control shall be properly disposed of in a manner such as to prevent any pollutant from such 

materials from entering waters of the state and in accordance with environmental regulations. 

7. Percent Removal

For publicly owned treatment works, the 30-day average percent removal for Biochemical Oxygen Demand 

and Total Suspended Solids shall not be less than 85 percent in accordance with LAC 33:IX.5905.A.3. and 

B.3.

authorized contractor acting as a representative of the Administrator), upon the presentation of credentials 

and other documents as may be required by the law to: 

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 

either a central or private office that is open only during normal office hours and is closed at the time of 

inspection, the records shall be made available as soon as the office is open, but in no case later than 

the close of business the next working day; 

c. Inspect at reasonable times any facilities, equipment (including monitoring and control equipment), 

practices, or operations regulated or required under this permit; and 

d. Sample or monitor at reasonable times, for the purposes of assuring permit compliance or as otherwise 

authorized by the Clean Water Act or the Louisiana Environmental Quality Act, any substances or 

parameters at any location. 

e. Sample Collection

(1) When the inspector announces that samples will be collected, the permittee will be given an 

additional thirty (30) minutes to prepare containers in order to collect duplicates. If the permittee 

cannot obtain and prepare sample containers within this time, he is considered to have waived his 

right to collect duplicate samples and the sampling will proceed immediately. Further delay on the 

part of the permittee in allowing initiation of the sampling will constitute a violation of this permit. 

(2) At the discretion of the administrative authority, sample collection shall proceed immediately 

(without the additional 30 minutes described in Section C.1.a. above) and the inspector shall supply 

the permittee with a duplicate sample.

17. Monthly Average, other than for fecal coliform bacteria, discharge limitations are calculated as the sum of all 

"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 flow is measured as continuous record or with a totalizer, the monthly average 

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

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

number of daily samples; monthly average discharge = 

 

C1F1 + C2F2 + ... + CnFn

F1 + F2 + ... + Fn

When the permit establishes monthly average concentration effluent limitations or conditions, and the flow 

is not measured as a continuous record, then the monthly average concentration means the arithmetic 

average of all "daily discharge(s)" of concentration determined during the calendar month. 

The monthly average for fecal coliform bacteria is the geometric mean of the values for all effluent samples 

collected during a calendar month. 

18. National Pollutant Discharge Elimination System (NPDES) means the national program for issuing,

enforcing pretreatment requirements, under Sections 307, 318, 402, and 405 of the Clean Water Act. 

19. Severe property damage means substantial physical damage to property, damage to the treatment facilities 

that causes them to become inoperable, or substantial and permanent loss of natural resources that can 

reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean 

economic loss caused by delays in production. 

20. Sewage sludge means a solid, semi-solid, or liquid residue generated during the treatment of domestic 

sewage in a treatment works. Sewage sludge includes, but is not limited to, domestic septage; scum or

sewage in a treatment works. 

21. Treatment works means any devices and systems used in the storage, treatment, recycling and reclamation 

of municipal sewage and industrial wastes of a liquid nature to implement Section 201 of the Clean Water 

Act, or necessary to recycle or reuse water at the most economical cost over the estimated life of the works, 

including intercepting sewers, sewage collection systems, pumping, power and other equipment, and their 

appurtenances, extension, improvement, remodeling, additions, and alterations thereof. (See Part 212 of the

27. Weekly average, other than for fecal coliform bacteria, is the highest allowable arithmetic mean of the daily 

discharges over a calendar week, calculated as the sum of all “daily discharge(s)” measured during a 

calendar week divided by the number of “daily discharge(s)” measured during that week. When the permit 

establishes weekly average concentration effluent limitations or conditions, and flow is measured as 

continuous record or with a totalizer, the weekly average concentration means the arithmetic average 

(weighted by flow) of all "daily discharge(s)" of concentration determined during the calendar week where C 

= daily discharge concentration, F = daily flow and n = number of daily samples; weekly average discharge 

C1F1 + C2F2 + ... + CnFn = F1 + F2 + ... + Fn

When the permit establishes weekly average concentration effluent limitations or conditions, and the flow is 

not measured as a continuous record, then the weekly average concentration means the arithmetic average 

of all "daily discharge(s)" of concentration determined during the calendar week. 

The weekly average for fecal coliform bacteria is the geometric mean of the values for all effluent samples 

collected during a calendar week. 

28. Sanitary Wastewater Term(s): 

a. 3-hour composite sample consists of three effluent portions collected no closer together than one hour 

(with the first portion collected no earlier than 10:00 a.m.) over the 3-hour period and composited 

according to flow, or a sample continuously collected in proportion to flow over the 3-hour period. 

b. 6-hour composite sample consists of six effluent portions collected no closer together than one hour 

(with the first portion collected no earlier than 10:00 a.m.) over the 6-hour period and composited 

according to flow, or a sample continuously collected in proportion to flow over the 6-hour period.

c.12-hour composite sample consists of 12 effluent portions collected no closer together than one hour 

over the 12-hour period and composited according to flow, or a sample continuously collected in 

proportion to flow over the 12-hour period. The daily sampling intervals shall include the highest flow 

periods. 

 d. 24-hour composite sample consists of a minimum of 12 effluent portions collected at equal time 

intervals over the 24-hour period and combined proportional to flow or a sample continuously collected 

in proportion to flow over the 24-hour period.

APPENDIX C 

LAG530000 

Turbidity limitations will be required if they are established in a finalized TMDL or other wasteload allocation, and this 

TMDL or wasteload allocation establishes the limitation at the standard found in LAC 33:IX.113.B.9.i-vi. Also, on a caseby-case basis, the turbidity limitation could be imposed on a facility to address a 303(d) impairment without a finalized 

TMDL. 

As per LAC 33:IX.1113.B.9.i-vi, turbidity shall be limited as shown in the following table. Maximum turbidity levels are 

expressed as nephelometric turbidity units, or NTUs. 

Discharges must be directly into one of the below named waterbodies in order for the effluent limitation to apply.

1 LAC 33:IX.1121.B.3.b.iii.(d) refers to marine as water bodies with salinities equal or greater than two parts per 

thousand. The same principle applies here. 

2 LAC 33:IX.1121.B.3.b.iii.(a) refers to freshwater as water bodies with salinities less than two parts per thousand. 

The same principle applies here. 

3

 Outstanding natural resource waters include water bodies designated for preservation, protection, reclamation, or 

enhancement of wilderness, aesthetic qualities, and ecological regimes, such as those designated under the 

Louisiana Natural and Scenic Rivers System or those designated by the office as waters of ecological significance. 

This use designation applies only to the water bodies specifically identified in Table 3 (LAC 33:IX.1123) and not 

to their tributaries or distributaries unless so specified. 

4

 Background refers to the average presence in the environment, originally referring to naturally occurring 

phenomena. The ambient instream concentration for a pollutant. (EPA, 1989) The permittee shall analyze at least 

three upstream samples for turbidity. The arithmetic average of these samples equals the background turbidity, or 

B. The calculation for finding 10% of the background turbidity is shown below: 

 B x 0.1 = X 

 

 10% of the background turbidity is denoted by X. Turbidity limit = B + X.
