I. Permit Coverage 

A. Facilities Authorized to Discharge under this Permit 

The following facilities are authorized to discharge to receiving waters of the United States, 

after obtaining authorization under the provisions of Part I.C: 

Idaho cold water and warm water aquaculture facilities (also known as concentrated 

aquatic animal production facilities (see 40 CFR §122.24 and §122 Appendix C)) that are 

listed in Tables 2 –10, below. These are facilities that have been provided wasteload 

allocations (WLAs) in a Total Maximum Daily Load (TMDL) approved by EPA as of the 

effective date of this permit. 

B. New Sources 

New aquaculture facilities that are constructed after September 22, 2004, are new sources, as 

defined in 40 CFR §§122.2, and 122.29. A facility is a "new source" if (1) the facility is 

constructed at a site where no other facility is located, (2) the facility totally replaces the 

process or production equipment that causes the discharge of pollutants at the existing 

facility, or (3) the facility processes are substantially independent of an existing facility at the 

same site. See 40 CFR §122.29(b) and (c). 

The new source facility must prepare and submit an Environmental Information Document to 

EPA. This document needs to address the potential environmental effects of the new source 

discharge to the receiving environment. New sources may be required to apply for an 

individual permit. 

C. Obtaining Authorization to Discharge under this General Permit 

1. Where to Submit the Notice of Intent (NOI) 

An owner or operator of a facility seeking authorization to discharge under this permit 

must submit an NOI to be covered to EPA at the address below; for permittees who 

submitted an NOI in 2004, see § I.C.3.a, below. A copy of the NOI must also be sent to 

the appropriate regional office of Idaho Department of Environmental Quality (IDEQ):

Requirements), and a copy must be retained on site, in accordance with Part V.F 

(Retention of Records). 

3. Deadlines for Submitting the Notice of Intent 

a. Permittees under the 1999 General Permit 

(1) Facilities that submitted an NOI and are currently operating. 

A permittee with extended coverage under the 1999 General Permit who 

submitted an NOI between January 1, and September 27, 2004 is not required to 

submit an NOI if the permitted facility is containing, growing, or holding fish at 

the facility on the effective date of this permit See Appendix B for a list of the 

facilities who submitted NOIs in this time period. 

(2) Facilities that submitted an NOI but are not currently operating. 

A permittee who submitted an NOI between January 1, and September 27, 2004 

but who was not containing, growing, or holding fish at the permitted facility on 

the effective date of this permit must submit a revised NOI and notification of 

impending start-up at least 45 days before the projected date of initial discharge. 

See Appendix B for a list of the facilities who submitted NOIs in this time period. 

(3) Facilities that did not submit an NOI but are currently operating. 

A permittee who failed to submit an NOI to extend coverage under the 1999 

General Permit must apply for coverage under this permit within 45 days after the 

effective date of this permit. 

b. Existing Permittees under individual permits

Page 8 of 96 

c. Permittees continuing discharge beyond the expiration date of this permit 

A permittee who intends to continue discharging to waters of the U.S. after the 

expiration date of this permit must submit an NOI at least 180 days prior to the 

expiration date in accordance with Part VII.B. Under all circumstances, even if the 

facility is no longer operating, a permittee must have coverage under an NPDES 

permit until it has properly disposed of wastewater or solids that were generated at the 

facility, collected in a raceway or settling basin, or held in storage. If the facility is no 

longer operating but is still discharging when the permit is due to expire, the 

permittee must reapply for coverage. 

d. Dischargers resuming operation 

A discharger resuming operation of a facility listed in Tables 2 – 10 who seeks 

coverage under this permit must submit an NOI at least 45 days prior to 

commencement of operation and discharge of pollutants. 

4. When the Permittee Is Authorized to Discharge 

a. An existing permittee who submitted an NOI between January 1, 2004, and 

September 27, 2004, shall be authorized to discharge under this permit 30 days 

after publication of this General Permit in the Federal Register as long as the 

facility is containing, growing, or holding fish on the effective date of this 

permit. A list of the facilities who submitted NOIs in this time period is in 

Appendix B. 

b. Any discharger who did not submit an NOI between January 1, 2004, and 

September 27, 2004, is not authorized to discharge until EPA notifies the 

discharger, in writing, that coverage has been granted and that a specific permit 

number has been assigned to the discharger. 

c. Any operator who submitted an NOI between January 1, 2004, and September 

27, 2004, but was not containing, growing, or holding fish at the facility on the 

effective date of this permit, is not authorized to discharge until EPA notifies 

the operator, in writing, that coverage has been granted. The operator must 

submit a revised NOI and notification of impending start-up at least 45 days 

before the projected date of initial discharge. 

D. Notification of Coverage 

EPA may notify a discharger that it is covered by this general permit, even if the discharger 

has not submitted an NOI (40 CFR §122.28(b)(2)(vi)). 

E. Requirement to Apply for Individual Permit 

1. EPA may require any discharger requesting coverage under this general permit to 

apply for and to obtain an individual NPDES permit in accordance with 40 CFR 

§122.28(b)(3)(i). Cases where an individual NPDES permit may be required 

include, but are not limited to, those where the single discharge is, alone or with 

others, a significant contributor of pollution; where the permittee is not in 
Permit No.: IDG-130000 

Page 9 of 96 

compliance with the terms and conditions of the general permit; or, where a Total 

Maximum Daily Load (TMDL) has been completed for a waterbody or a segment 

of a waterbody. 

2. Any permittee authorized by this general permit may request to be excluded from 

the coverage of the general permit by applying for an individual permit. The 

permittee shall submit an individual permit application with reasons supporting the 

request to EPA no later than 90 days after the publication by EPA of the general 

permit in the Federal Register. 

F.Termination or Inactivation of Authorization to discharge 

Under all circumstances, a permittee must be covered under this permit until it has properly 

disposed of wastewater or solids that were generated at the facility or collected in a raceway 

or settling basin or held in storage, at least until the facility is no longer discharging to waters 

of the United States. If the facility still has a potential to discharge when the permit is due to 

expire, the permittee must reapply for coverage. If a permittee whose authorization to 

discharge has been terminated or inactivated under §§1 or 2 below wants to resume 

operation, it must request authorization in writing from EPA and IDEQ at least 45 days 

before resumption of operation. 

1. Permanent Termination of Authorization to discharge 

Authorization to discharge under this permit is terminated when EPA receives a 

permittee’s notification in writing of cessation of operation or permanent change in 

operation that reduces the production level to below 20,000 pounds fish produced and to 

below 5,000 pounds of feed in every month for cold water production, or to below 

100,000 pounds of fish per year for warm water production. The permittee must also 

submit the notification to IDEQ. 

2. Temporary Shutdown of production activities 

Authorization to discharge is inactivated when EPA receives a permittee’s notification in 

writing of temporary shutdown of operation or temporary change in operation that: 

a. for cold water aquaculture facilities, reduces the annual production level to 

below 20,000 pounds of fish or the feed level to below 5,000 pounds of feed in 

every month, or 

b. for warm water aquaculture facilities, reduces the annual production level to 

less than 100,000 pounds of fish produced. 

The permittee must also submit the notification to IDEQ. 

II. Limitations and Monitoring Requirements 

During the effective period of this permit, the permittee is authorized to discharge pollutants 

from the outfall(s) specified in its NOI within the limits and subject to the conditions set forth in 

this permit. This permit authorizes the discharge of only those pollutants resulting from facility 
Permit No.: IDG-130000 

Page 10 of 96 

processes, waste streams, and operations that have been clearly identified in the NOI, including 

non-production facilities, such as incubators, laboratories, tagging operations, etc. It does not 

authorize the discharge of any waste streams, including spills and other unintentional or nonroutine discharges of pollutants, that are not part of the normal operation of the facility as 

disclosed in the permittee’s NOI, nor does it authorize the discharge of any pollutants that are not 

ordinarily present in such waste streams. 

A. Effluent Limitations 

The permittee must limit discharges from all outfalls authorized under this permit as 

specified in Tables 1 -- 11, below. All limits represent maximum effluent limits, unless 

otherwise indicated. Many limits are “net”, i.e. effluent minus influent. The permittee must 

comply with the applicable effluent limits in the tables at all times, unless otherwise 

indicated, regardless of the frequency of monitoring required in Tables 12 and 13, below, or 

reporting required by Part V.B, below. The limitations on discharges from off-line settling 

basins, listed in Table 11, apply in addition to the facility-specific limitations in Tables 2 – 

10. 

1. Pollutant Trading. A permittee authorized to discharge under this permit may 

engage in pollutant trading, pursuant to the requirements in Idaho’s Water Quality 

Pollutant Trading Guidance 2003. However, a buyer of credits is not allowed to 

increase its average monthly discharge of a pollutant above the alternate 

technology-based limit applicable to the facility for raceways and full-flow settling 

basin discharges; see Table 1 for total phosphorus trading limits, as an example. 

No trading is allowed to adjust discharges to meet maximum daily limits. See 

Appendix C for details about the requirements for purchasing and selling pollutant 

credits and reporting such trades to EPA and IDEQ. 

2. Upper Snake Rock Facilities. 

a. Pollutant Trading. A permittee authorized to discharge under this permit into 

the Upper Snake Rock Watershed may engage in phosphorus trading. See 

§II.A.1, above, for specific limitations on trading. See Table 1, below, for the 

technology-based limits for raceways and full-flow settling basin discharges, 

which provide the upper limit on buying phosphorus credits in this watershed. 

In addition, some facilities whose average monthly limits were set at the 

technology-based limit cannot buy credits to adjust their discharges of total 

phosphorus upward; these limitations are noted in Tables 2 and 3 by footnotes 

on these facilities.

 FBI Catfish may only buy credits up to this limit between March and August, inclusive. For the rest of the year, a 

technology-based average monthly limit for total phosphorus applies and precludes buying of phosphorus credits. 

The only other warm water facility in the Upper Snake Rock subbasin is Canyon Springs; since it has a technologybased AML for total phosphorus, it cannot buy credits. 

b. Effluent Limitations for facilities in the Upper Snake Rock Watershed, except 

Billingsley Creek; see Table 2. Some facilities also have seasonally variable 

limits which are listed in Table 3. For limitations on facilities on Billingsley 

Creek, see Table 4.

B. Prohibited Discharges 

1. Discharges from aquaculture facilities must not cause or contribute to a violation of 

Idaho State Water Quality Standards. 

2. The permittee must not discharge to waters of the U.S.: 

a. Any floating solids or visible foam in other than trace amounts on the surface of 

the receiving water; 

b. Any hazardous materials in concentrations found to be of public health 

significance or to impair designated beneficial uses; 

c. Any sludge, grit and accumulated solid residues; 

d. Any untreated cleaning wastewater (e.g., obtained from a vacuum or standpipe 

bottom drain system or rearing/holding unit disinfection); or 

e. Any floating, suspended or submerged matter, including dead fish, in amounts 

causing nuisance or objectionable condition or that may impair designated 

beneficial uses in the receiving water. 

f. Any toxic substances, including drugs, pesticides, or other chemicals, in 

concentrations that impair designated uses. 

g. Any deleterious materials in concentrations that impair designated beneficial 

uses. 

h. Any oxygen-demanding materials in concentrations that would result in an 

anaerobic water condition. 

C. Prohibited Practices 

The permittee is prohibited from engaging in any of the following practices: 

1. Practices (e.g., the removal of dam boards in raceways or ponds) which allow 

accumulated solids to be discharged to waters of the United States. 

2. Sweeping, raking, or otherwise intentionally discharging accumulated solids from 

raceways or ponds to waters of the United States. 
Permit No.: IDG-130000 

Page 30 of 96 

3. Containing, growing or holding fish within an offline or full-flow settling basin; this 

prohibition does not apply to “basins” or ponds where fish are used as part of the 

waste treatment system. 

4. Containing, growing or holding transgenic or non-native fish or eggs without a 

current permit issued by the Idaho Department of Fish and Game for importation, 

transportation or release or sale or export for such species, unless a permit is not 

required under IDAPA §13.01.10.100. 

D. Facility Monitoring Requirements 

1. The permittee must monitor discharges from all outfalls authorized under this 

permit as specified in Tables 12 and 13, below. 

2. Method Detection Limits (MDL). 

a. The permittee must use methods that can achieve method detection limits less 

than or equal to those specified in Table 15 (see Part II.E). 

b. For purposes of reporting on the DMR, if a value is greater than the method 

detection limit, the permittee must report the actual value. If an influent or 

effluent value is less than the MDL, the permittee must report “less than 

{numeric MDL}” on the DMR, but use one-half the MDL when calculating the 

net value. If both influent and effluent values are less than the MDL, the 

permittee must report “less than {numeric MDL}” on the DMR, and use onehalf the MDL for calculating monthly averages. See Appendix D. 

3. Monitoring requirements for discharges from raceways and full-flow settling 

basins; see Table 12. 

a. Timing. All influent and effluent samples and flow measurements must be 

taken on the same day. Facilities with multiple effluent discharge points and/or 

influent points must composite samples from all points proportionally to their 

respective flows. Only the composite sample must be analyzed. 

b. Location. The permittee must collect effluent samples from the effluent stream 

just prior to discharge into the receiving waters or, if it mixes with other flows 

prior to discharge, just before the subsequent mixing with other flows. For 

facilities with raceway(s) discharging to a full-flow settling basin(s), the 

permittee must collect effluent samples from the full-flow settling basin(s) just 

prior to discharge into the receiving waters. 

c. Small discharges. Facilities with small discharges that comprise less than 1% of 

the total raceway flows are not required to monitor these discharges for 

pollutant quality as long as the effluent quality of these discharges is 

substantially identical to monitored discharges from the facility, and the 

permittee provides in its Quality Assurance Plan the justification for excluding 

such discharges from its routine effluent pollutant monitoring. Such 

justification must address the reason the effluent quality is expected to be 
Permit No.: IDG-130000 

Page 31 of 96 

identical to the monitored outfall and the quantification that shows the sum of 

such flows is less than one percent of the monitored outfall’s flow; see Part 

II.G, Quality Assurance Plan. The flow of these small discharges must be 

monitored at a minimum of once per year, and the flow data used in calculating 

facility pollutant loads.

13 Monitoring must begin in the first full calendar month of permit coverage. 

14 Flow measurement method must be one of those specified in Appendix E, §I. A, unless IDWR authorizes a nonstandard device as allowed in § I.B. This requirement applies to measuring flow at each point where pollutants are 

measured. 

15 Flow measurement must be taken concurrently with each pollutant sampling, when applicable, once for every 

composite sample; it may be taken on either the influent or effluent as long as the measurement at that location 

accurately reflects the discharge flow to the receiving water. 16 For facilities that produce between 100,000 and 500,000 pounds of harvestable weight of fish per year, this 

monitoring is only required once per calendar quarter, beginning in the first full calendar quarter after the permit’s 

effective date. For facilities that produce less than 100,000 pounds of harvestable weight of fish per year, this 

monitoring is only required twice per calendar year, once in January – June and once in July – December, beginning 

in the first full calendar half year after the permit’s effective date. 

17 Composite samples must consist of four (4) or more discrete samples taken at one-half hour intervals or greater in 

a 24-hour period; at least one fourth of the samples must be taken during quiescent zone or raceway cleaning. 

Facilities with multiple effluent discharge points and/or influent points must composite samples from all points 
Permit No.: IDG-130000 

Page 32 of 96 

proportionally to their respective flows. Only the composite sample must be analyzed. Facilities using spring water 

as influent sources may elect to take grab samples instead of composite, when influent water quality is shown to not 

vary during the course of the day. 

18 All influent and effluent samples and flow measurements must be taken on the same day.

19 See Appendix D (Effluent Calculations) for guidance on calculating loads.

20 Temperature monitoring is only required for discharges from warm-water facilities. 21 Only when using chelated copper compounds or copper sulfate. 22 Quarterly monitoring is required by calendar quarters and must begin in the first full calendar quarter after permit

issuance. 

23 Monitoring of total inorganic nitrogen (total ammonia plus nitrate and nitrite) is required only for Batise Springs 

Trout Farm. 

24 Monitoring of total nitrogen (total Kjeldahl nitrogen plus nitrate and nitrite) is required only for Springfield 

Hatchery. 

4. Off-Line Settling Basin Additional Limitations. These limitations and monitoring 

requirements apply to any discharge directly to waters of the U.S. from an offline 

settling basin. See Table 13. The permittee must collect effluent samples from the 

effluent stream just prior to discharge into the receiving waters..

27 Flow measurement method must be one of those specified in Appendix E, § I. A, unless IDWR authorizes a nonstandard device as allowed in § I.B. This requirement applies to measuring flow at each point where pollutants are 

measured. Alternatively to an IDWR approved method, the total volume discharged can be calculated by 

multiplying the pump time and the pump rate during cleaning. 
Permit No.: IDG-130000 

Page 33 of 96 

28 OLSB effluent or influent: Flow measurement must be taken concurrently with pollutant sampling, when 

applicable; it may be taken on either the OLSB influent or effluent as long as the measurement at that location 

accurately reflects the discharge flow to the receiving water. 

29 For facilities that produce between 100,000 and 500,000 pounds of harvestable weight of fish per year, this 

monitoring is only required once per calendar quarter, beginning in the first full calendar quarter after the permit’s 

effective date. For facilities that produce less than 100,000 pounds of harvestable weight of fish per year, this 

monitoring is only required twice per calendar year, once in January – June and once in July – December, beginning 

in the first full calendar half year after the permit’s effective date. 

30 Composite samples must consist of four (4) or more discrete samples taken at one-half hour intervals or greater in 

a 24-hour period. Facilities with multiple effluent discharge points and/or influent points must composite same day 

samples from all points proportionally to their respective flows. Only the composite sample must be analyzed. If 

multiple OLSB discharges occur on different days, sample results may be averaged when calculating the average 

monthly concentration and load. Facilities using spring water as influent sources for determining net pollutant 

discharges may elect to take grab samples instead of composite, when influent water quality is shown to not vary 

during the course of the day. 

31 Facility influent and OLSB effluent. The collection and analysis of facility influent samples is optional for this 

calculation only. If an influent sample is not collected and analyzed, then the influent concentration must be 

considered to be equal to zero. 

32 Lbs/day = mg/l * effluent flow (cfs) * 5.4 

33 OLSB effluent and OLSB influent. See Appendix D for guidance on the calculation. 34 Quarterly monitoring is required by calendar quarters and must begin in the first full calendar quarter after permit 

issuance. 

35 Temperature and pH readings must be taken in conjunction with each grab sample taken for the composite 

ammonia sample and the results averaged and reported on the monthly discharge monitoring reports (DMRs). 

E. Receiving Water Monitoring 

1. All permittees with offline settling basins that discharge directly to receiving water 

must conduct receiving water monitoring quarterly for ammonia, pH, and 

temperature upstream from the outfall. 

2. All facilities that use chelated copper compounds or copper sulfate must monitor 

total recoverable copper and hardness immediately upstream of the outfall at least 

once in any quarter when these compounds are applied; such monitoring should be 

roughly at the same time as the copper and hardness effluent monitoring. 

3. All receiving water samples must be grab samples and must be collected during the 

time when effluent composite samples are being collected for the same parameters; 

multiple grab samples are not required. 

4. All receiving water samples must be analyzed using EPA approved methods 

capable of achieving method detection limits (MDLs) that are equivalent to or less 

than those listed in Table 15. The permittee may request different MDLs if its 

results have consistently been above the required MDLs. Such a request must be in 

writing and must be approved by EPA before the permittee may use the revised 

MDLs. 

5. Receiving water monitoring may be conducted jointly with nearby dischargers in 

cases where the background (upstream) monitoring would be located in similar 

locations, e.g. where both discharge into the same lake. Such discharge locations 

must be chosen in consultation with IDEQ and EPA and be documented in each 
Permit No.: IDG-130000 

Page 34 of 96 

facility’s QA plan. Each facility remains responsible for ensuring the monitoring is 

conducted and submitting the results to EPA and IDEQ by the due date specified in 

§II.E.6, below.

6. Receiving water monitoring results must be submitted to EPA with copies to IDEQ 

with the DMRs for the month when the monitoring is conducted. The report must 

include all information required in Part V.E. and a summary and evaluation of the 

analytical results, including a short discussion of the accuracy and precision of the 

data, any problems with sample collection or analysis that may have affected the 

results, or what conditions existed at the time of the sample collection that may be 

relevant to how representative the data may be of the normal conditions at that site. 
Permit No.: IDG-130000 

Page 35 of 96 

7. Quality assurance/quality control plans for all the monitoring must be documented 

in the Quality Assurance Plan required under Part II.F (Quality Assurance Plan). 

F. Quality Assurance (QA) Plan 

The permittee must develop a quality assurance (QA) plan for all monitoring required by this 

permit. The plan must be developed and implemented within 60 days of coverage under this 

permit. Any existing QA Plans may be modified to meet this requirement. A permittee must 

certify that a QA Plan has been developed and is being implemented and must submit the 

certification, which includes the information specified in Appendix F, to EPA and to the 

responsible IDEQ office (§I.C.1, above) within 90 days of the effective date of this permit. 

A new permittee must submit the certification with the written Notice of Intent to be covered 

under this permit. 

1. The QA Plan must be designed to assist in planning for the collection and analysis of 

effluent and receiving water samples in support of the permit and in explaining data 

anomalies when they occur. 

2. Throughout all sample collection and analysis activities, the permittee must use the 

EPA-approved quality assurance and quality control (QA/QC) and chain-of-custody 

procedures described in Requirements for Quality Assurance Project Plans (EPA/QA/R5)1

 and Guidance for Quality Assurance Project Plans (EPA/QA/G-5)2. The QA Plan 

must be prepared in the format that is specified in these documents. 

3. At a minimum, the QA Plan must include the following: 

a) Details on the number of samples, type of sample containers, preservation of 

samples including temperature requirements, holding times, analytical methods, 

analytical detection and quantification limits for each parameter, type and number of 

quality assurance field samples, precision and accuracy requirements, sample 

preparation requirements, sample shipping methods, and laboratory data delivery 

requirements. See Parts V.A.-F for additional requirements. 

b) Description of flow measuring devices or methods used to measure influent and/or 

effluent flow at each point, calibration procedures, and calculations used to convert to 

flow units. If a permittee’s facility has multiple effluent discharge points and/or 

influent points, it must describe its method of compositing samples from all points 

proportionally to their respective flows. 

(1) A permittee using water from multiple springs as its influent must provide 

evidence of insignificant variability among its influent sources over the course of 

a day, if it elects to take grab samples instead of composites from each source 

when conducting influent sampling. 

(2) A permittee who elects to not monitor small discharges that comprise less 

than 1% of the total raceway flows must provide justification that the effluent 

quality of these discharges is substantially identical to monitored discharges from 

the facility and that the flows are less than 1% of the monitored outfall’s flow.

Page 36 of 96 

The rationale must include a comparison of pollutant sampling results from both 

these small discharges and the main discharge point(s). 

c) Maps indicating the location of each sampling point, including receiving water 

sampling locations and justification for the choice of the sampling location. The 

location of the small discharges that comprise less than 1% of the total raceway flows 

must also be included. 

d) Qualification and training of personnel. 

e) Name, address and telephone number of the laboratory used by or proposed to be 

used by the permittee. 

4. The permittee must amend the QA Plan whenever there is a modification in sample 

collection, sample analysis, or other procedure addressed by the QA Plan and must 

update it whenever there is a change in ownership or operator. 

5. Copies of the QA Plan must be kept on site and made available to EPA and IDEQ 

upon request. If lack of suitable storage area makes on-site storage impossible, the QA 

Plan must be in the possession of staff whenever they are working on-site. 

III. Best Management Practices Plan 

A. Purpose 

Through implementation of the best management practices (BMP) plan, the permittee must 

prevent or minimize the generation and discharge of wastes and pollutants from the facility

Page 40 of 96 

D. Annual Report of Operations 

During the term of this permit, the permittee must prepare and submit an annual report of 

operations by January 20th of each year to EPA and IDEQ. A copy of the annual report 

and the data used to compile it must be available to EPA and IDEQ upon request and 

during inspections. The report must include the information specified in Appendix H. 

V. Standard Monitoring, Recording and Reporting Requirements 

A. Representative Sampling (Routine and Non-Routine Discharges) 

Samples and measurements must be representative of the volume and nature of the 

monitored discharge or source water. 

In order to ensure that the effluent limits set forth in this permit are not violated at times 

other than when routine samples are taken, the permittee must collect additional samples at 

the appropriate outfall whenever any discharge occurs that may reasonably be expected to 

cause or contribute to a violation that is unlikely to be detected by a routine sample. The 

permittee must analyze the additional samples for those parameters limited in Part II.A. 

(“Effluent Limitations”) that are likely to be affected by the discharge. 

The permittee must collect such additional samples as soon as the spill, discharge, or 

bypassed effluent reaches the outfall. The samples must be analyzed in accordance with 

Part V.C (“Monitoring Procedures”). The permittee must report all additional monitoring in 

accordance with Part V.D (“Additional Monitoring by Permittee”). 

B. Reporting of Monitoring Results 

The permittee must summarize monitoring results, including influent, effluent, and net 

results, each month on the Discharge Monitoring Report (DMR) form (EPA No. 3320-1) or 

equivalent. 

1. Paper copy submissions. 

The permittee must submit reports monthly, postmarked by the 20th day of the 

following month. Permittees eligible for pollutant trading must submit DMRs which 

provide the “adjusted discharge” postmarked by the 10th day of the second month 

following sampling, attaching the Trade Summary Report provided by the Idaho Clean 

Water Cooperative. The permittee must also submit an annual report as required in 

§IV.D, above.

punished by a fine of not more than $10,000 per violation, or by imprisonment 

for not more than 6 months per violation, or by both. 

C. Need To Halt or Reduce Activity not a Defense 

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

necessary to halt or reduce the permitted activity in order to maintain compliance with this 

permit. 

D. Duty to Mitigate 

The permittee must take all reasonable steps to minimize or prevent any discharge in 

violation of this permit that has a reasonable likelihood of adversely affecting human health 

or the environment. 

E. Proper Operation and Maintenance 

The permittee must 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 controls and appropriate quality assurance 

procedures. This provision requires the operation of back-up or auxiliary facilities or 

similar systems which are installed by the permittee only when the operation is necessary to 

achieve compliance with the conditions of the permit. 

F. Bypass of Treatment Facilities 

1. Bypass not exceeding limitations. The permittee may allow any bypass to occur 

that 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 §§ VI.F.2 and 3, below. 

2. Notice. 

a. Anticipated bypass. If the permittee knows in advance of the need for a bypass, 

it must submit prior notice, if possible at least 10 days before the date of the 

bypass. 
Permit No.: IDG-130000 

Page 46 of 96 

b. Unanticipated bypass. The permittee must submit notice of an unanticipated 

bypass as required under Part V.G (“Twenty-four Hour Notice of 

Noncompliance Reporting”). 

3. Prohibition of bypass. 

a. Bypass is prohibited, and the Director of the Office of Compliance and 

Enforcement or IDEQ may take enforcement action against the permittee for a 

bypass, unless: 

(1) The bypass was unavoidable to prevent loss of life, personal injury, or 

severe property damage; 

(2) 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 that 

occurred during normal periods of equipment downtime or preventive 

maintenance; and 

(3) The permittee submitted notices as required under §VI.F.2, above. 

b. The Director of the Office of Compliance and Enforcement and IDEQ may 

approve an anticipated bypass, after considering its adverse effects, if the 

Director and IDEQ determine that it will meet the three conditions listed above 

in §VI.F.3.a. 

G. Upset Conditions 

1. 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 

permittee meets the requirements of §2 of this Part. 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. 

2. Conditions necessary for a demonstration of upset. To establish the affirmative 

defense of upset, the permittee must demonstrate, through properly signed, 

contemporaneous operating logs, or other relevant evidence that: 

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

b. The permitted facility was at the time being properly operated; 

c. The permittee submitted notice of the upset as required under Part V.G 

(“Twenty-four Hour Notice of Noncompliance Reporting”); and 

d. The permittee complied with any remedial measures required under Part VI.D 

(“Duty to Mitigate”). 

3. Burden of proof. In any enforcement proceeding, the permittee seeking to establish 
Permit No.: IDG-130000 

Page 47 of 96 

the occurrence of an upset has the burden of proof. 

H. Toxic Pollutants 

The permittee must comply with effluent standards or prohibitions established under 

Section 307(a) of the Act for toxic pollutants within the time provided in the regulations 

that establish those standards or prohibitions, even if the permit has not yet been modified 

to incorporate the requirement. 

I. Planned Changes 

1. The permittee must give notice as soon as possible to the Director of the Office of 

Water and Watersheds and to IDEQ, as specified in § I.C.1, of any planned 

physical alterations or additions to the permitted facility whenever: 

a. The alteration or addition to a permitted facility may meet one of the criteria for 

determining whether a facility is a new source as determined in 40 CFR 

§122.29(b); or 

b. The alteration or addition, including production changes, could significantly 

change the nature or increase the quantity of pollutants discharged. This 

notification applies to pollutants that are not subject to effluent limitations in 

the permit. 

2. A permittee must submit to IDEQ all plans and specifications for the construction, 

modification, expansion, or alteration of waste treatment or disposal facilities for 

review and approval before construction may begin (Idaho Code §39-118). 

J. Anticipated Noncompliance 

The permittee must give advance notice to the Director of the Office of Compliance and 

Enforcement and IDEQ of any planned changes in the permitted facility or activity that may 

result in noncompliance with this permit. 

VII. General Provisions 

A. Permit Actions 

This permit or coverage under this permit may be modified, revoked and reissued, or 

terminated for cause as specified in 40 CFR §§122.62, 122.64, or 124.5. The filing of a 

request by the permittee for a permit modification, revocation and reissuance, termination, 

or a notification of planned changes or anticipated noncompliance does not stay any permit 

condition. 

B. Duty to Reapply 

If the permittee intends to continue an activity regulated by this permit after the expiration 

date of this permit, the permittee must submit a Notice of Intent. In accordance with 40 

CFR §122.21(d), the permittee must submit a new Notice of Intent at least 180 days before 
Permit No.: IDG-130000 

Page 48 of 96 

the expiration date of this permit, unless the Regional Administrator has granted permission 

to submit the Notice of Intent at a later date. If the NOI is received by that deadline, even if 

the permit is not reissued before the expiration date, the conditions of the permit will 

continue in force until the effective date of the subsequently reissued permit. If the facility 

is no longer operating but still has a potential to discharge when the permit is due to expire, 

the permittee must reapply for coverage. 

C. Duty to Provide Information 

The permittee must furnish to EPA and IDEQ, within the time specified in the request, any 

information that EPA or IDEQ may request to determine whether cause exists for 

modifying, revoking and reissuing, or terminating this permit, or to determine compliance 

with this permit. The permittee must also furnish to EPA or IDEQ, upon request, copies of 

records required to be kept by this permit. 

D. Other Information 

When the permittee becomes aware that it failed to submit any relevant facts in a Notice of 

Intent, or that it submitted incorrect information in a Notice of Intent or any report to EPA 

or IDEQ, it must promptly submit the omitted facts or corrected information. 

E. Signatory Requirements

responsibility for the overall operation of the regulated facility or activity, such 

as the position of plant manager, superintendent, position of equivalent 

responsibility, or an individual or position having overall responsibility for 

environmental matters for the company; and 

c. The written authorization is submitted to the Director of the Office of 

Compliance and Enforcement and IDEQ. 
Permit No.: IDG-130000 

Page 49 of 96 

3. Changes to authorization. If an authorization under §VII.E.2 is no longer accurate 

because a different individual or position has responsibility for the overall 

operation of the facility, a new authorization satisfying the requirements of 

§VII.E.2. must be submitted to the Director of the Office of Compliance and 

Enforcement and IDEQ prior to or together with any reports, information, or 

applications to be signed by an authorized representative. 

4. Certification. Any person signing a document under Part VII.E must make the 

following certification: 

“I certify under penalty of law that this document and all attachments were 

prepared under my direction or supervision in accordance with a system designed 

to assure that qualified personnel properly gather and evaluate the information 

submitted. Based on my inquiry of the person or persons who manage the system, 

or those persons directly responsible for gathering the information, the 

information submitted is, to the best of my knowledge and belief, true, accurate, 

and complete. I am aware that there are significant penalties for submitting false 

information, including the possibility of fine and imprisonment for knowing 

violations.” 

F.Availability of Reports 

In accordance with 40 CFR Part 2, information submitted to EPA pursuant to this permit 

may be claimed as confidential by the permittee. In accordance with the Act, Notices of 

Intent, permits and effluent data are not considered confidential. Any confidentiality claim 

must be asserted at the time of submission by stamping the words “confidential business 

information” on each page containing such information. If no claim is made at the time of 

submission, EPA may make the information available to the public without further notice to 

the permittee. If a claim is asserted, the information will be treated in accordance with the 

procedures in 40 CFR 2, Subpart B (Public Information) and 41 Fed. Reg. 36902 through 

36924 (September 1, 1976), as amended. 

G. Inspection and Entry 

The permittee must allow the Director of the Office of Compliance and Enforcement, EPA 

Region 10; IDEQ; or an authorized representative (including an authorized contractor 

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

other documents as may be required by law, to: 

1. 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; 

2. Have access to and copy, at reasonable times, any records that must be kept under 

the conditions of this permit; 

3. Inspect at reasonable times any facilities, equipment (including monitoring and

compliance or as otherwise authorized by the Act, any substances or parameters at 

any location. 

H. Property Rights 

The issuance of this permit does not convey any property rights of any sort, or any 

exclusive privileges, nor does it authorize any injury to persons or property or invasion of 

other private rights, nor any infringement of federal, tribal, state or local laws or 

regulations. 

I. Transfers 

Authorization to discharge under this permit may be automatically transferred to a new 

permittee on the date specified in the agreement only if: 

1. The current permittee notifies the Director of the Office of Water and Watersheds at 

least 30 days in advance of the proposed transfer date; 

2. The notice includes a written agreement between the existing and new permittees 

containing a specific date for transfer of permit responsibility and liability between 

them; and 

3. The Director does not notify the existing and new permittees of the intent to revoke 

and reissue the authorization to discharge. 

J. Permit reopener and modification. 

EPA is authorized to modify or revoke and reissue a permit pursuant to 40 CFR §122.62. 

Effluent limits, monitoring requirements or other permit conditions may be modified if new 

information is received which was not available at the time of issuance and would have 

justified the application of different permit conditions at the time of issuance (e.g. 

information showing violations of state water quality standards). This includes information 

indicating cumulative effects which are unacceptable. New information may originate from 

future waste load allocations and biological opinions issued pursuant to the Endangered 

Species Act. 

K. State Laws 

Nothing in this permit shall be construed to preclude the institution of any legal action or 

relieve the permittee from any responsibilities, liabilities, or penalties established pursuant

Pollutant Trading 

In The 

Upper Snake Rock Subbasin 

Aquaculture facilities in the Upper Snake Rock Watershed whose wastewater discharge 

is authorized under this permit are eligible to trade total phosphorus credits with other 

eligible point and non-point sources in this watershed, pursuant to the requirements in 

Idaho=s Water Quality Pollutant Trading Guidance 2003, Upper Snake Rock Watershed 

Management Plan, Modification, August 2005; and the conditions contained within this 

general permit. No permittee may buy credits that increase its average monthly discharge 

above its applicable technology-based total phosphorus limit. 

I. How to Buy Credits for Pollutant Trading 

A facility may purchase available phosphorus credits (in lbs/day for a specified 

month) from a point or nonpoint source using the Trade Tracking System 

operated by the Idaho Clean Water Cooperative to officially record the credit 

transaction. Acquiring such credits allows the facility to adjust the amount of its 

average monthly phosphorus discharge it reports on the Discharge Monthly 

Report (DMR) for that month by subtracting the amount of purchased credits 

from its actual discharge amount. The purchased credits are used to modify the 

actual average monthly phosphorus discharge rather than increase the limit 

because EPA’s system to track information reported on the DMR is not able to 

show how credit transactions adjust a permit limit. Therefore, the point source 

buyer instead must adjust its reported actual discharge for that month by 

subtracting the credit amount it has acquired and recorded in the Trade Tracking 

System. In the case of a point source seller, it must adjust its reported actual 

discharge for that month by adding the credit amount it has sold and recorded in 

the Trade Tracking System. 

II. Timing of Pollutant Trades 

Credits can only be traded for the calendar month in which the credit was 

generated (for example, the month in which the point source seller decreased its 

discharge of phosphorus below its average monthly limit to establish the amount 

of the credit). If a credit is acquired by a qualified aquaculture facility or fish 

processor, the resulting decrease in the buying facility=s reported average monthly 

phosphorus discharge is applicable only during the month associated with the 

credit. The purchase of phosphorus credits affects only the average monthly limit 

and does not affect the facility’s maximum daily phosphorus limit. 

III. Procedure for Transferring Credits 

To create a valid transfer of a credit, the eligible buyer and seller must complete a 

Trade Notification Form, available from the Idaho Clean Water Cooperative. The 

buyer must submit it to the Cooperative by the last day of the month following the 

generation of the credit. The Cooperative records the trade in the accounts for the 

buyer and seller in accordance with the information reported on the Trade 
Permit No.: IDG-130000 

Page 72 of 96 

Notification Form. 

IV. Reporting Pollutant Trades to EPA and IDEQ 

The permittee shall submit to EPA (with copies to IDEQ) a phosphorus-specific 

discharge monitoring report (DMR) and the Trade Summary Report provided by 

the Idaho Clean Water Cooperative. The Trade Summary Report will provide (A) 

the permittee’s actual average monthly phosphorus discharge (in lbs/day and 

mg/L); (B) the total amount of credits (in lbs/day) bought, if any; (C) the total 

amount of credits (in lbs/day) sold, if any; and (D) the permittee’s Aadjusted 

discharge@ (in lbs/day and mg/L), which is equal to A – B + C. The Permittee 

shall record both (A) and (D) on the DMR. 

All DMRs must be submitted in accordance with Section V.B. of the permit. The 

phosphorus-specific DMR which reports a trade provides the actual phosphorus 

and “adjusted discharge” and must be submitted by the 10th day of the second 

month following sampling. 

If the buyer and seller submit a Trade Notification Form to the Idaho Clean Water 

Cooperative but the credits are not available for transfer to the buyer, then the 

trade is not recorded in the Trade Tracking System and the buyer is subject to 

noncompliance penalties for any actual discharge over its average monthly limit. 

The amount of credits that are available for purchase is not the responsibility of 

EPA. Compliance with the permittee=s effluent limit shall only be affected by 

credits that have been validly transferred by the last day of the month following 

the generation of the credit. 

V. Recordkeeping System 

No trade is valid unless it is recorded through the Trade Tracking System 

operated by the Idaho Clean Water Cooperative (or alternatively, IDEQ, if the 

Cooperative has chosen to not operate the Trade Tracking System). The Idaho 

Clean Water Cooperative records all trades and generates a monthly summary 

report of all trades valid for each calendar month. The Trade Notification Form 

must be submitted to the Cooperative by the last day of the month following the 

generation of the credit in order for it to be recorded in the Trade Tracking 

System in time to be reported in the monthly Trade Summary Report and 

submitted with the permittee’s DMR postmarked by the 10th of the second month 

following the generation of the credit. 

VI. Termination of Trading 

IDEQ monitoring of the water quality of the receiving streams will be used to 

determine if localized impacts are occurring as a result of trades. IDEQ will 

inform the Idaho Clean Water Cooperative and the permittees affected if trading 

between specific facilities must be restricted because of localized impacts. Such 

restrictions may reduce the amount of credits available for transfer to prospective 

buyers within the affected reach.

Guidance on Calculating Effluent Values 

1. Calculating “Net” Effluent Values 

a. Pollutant Concentrations for TSS, Total Phosphorus, Total Nitrogen, and Total 

Inorganic Nitrogen (the last two for only one or two facilities) are measured at 

both influent and effluent monitoring locations. The net concentration is the 

difference between the two measurements and can either be positive or negative 

since the pollutant load may either increase or decrease as the water passes 

through the facility. It is calculated as follows: 

Effluent concentration (mg/l) – influent concentration (mg/l) = 

Net concentration (mg/l) 

2. Conversion from concentration to mass values: 

The following calculations are conducted separately for raceway discharges and for 

off-line settling basins (if applicable). The two results are added together to yield 

the total loading discharged from the facility; see step d, below. 

a. Pollutant levels are measured in terms of concentration, usually in 

milligrams/liter (mg/l). If they are reported in micrograms /liter (μg/l), divide by 

1000 to get the result in mg/l. 

1 μg x 1 mg = 0.001 mg/l 

liter 1000μg 

Therefore: μg/l / 1000 = mg/l 

b. Flow is usually measured in cubic feet per second (cfs) or gallons per minute 

(gpm). If it is measured in gpm, divide by 448.8 to convert to cfs. 

1 gallon x 1 minute x 1 cu. ft. = 1/448.8 cfs 

 minute 60 seconds 7.48 gals 

Therefore: gpm / 448.8 = cfs 

c. Load (in pounds/day) is calculated using the concentration and flow 

measurements for the day of pollutant sampling: 

1 mg x 28.3 liters x cu. ft. x 86400 secs x 2.2 lbs = lbs/day 

l cu. ft sec. day 1,000,000 mg 
Permit No.: IDG-130000 

Page 76 of 96 

Therefore: mg/l × cfs × 5.4 = lbs/day 

d. Total facility loading (in pounds/day) is calculated by adding the loading from 

the raceways and the loading from the off-line settling basins. 

Raceway loading (lbs/day) + OLSB loading (lbs/day) = 

Total facility loading (lbs/day) 

3. Calculating Per Cent Removal of TSS for OLSBs 

OLSB influent concentrat OLSB -ion effluent concentrat ion 

×100 = removal % 

OLBS effluent concentrat ion

4. DMR Reporting 

a. Values greater than the method detection limit (MDL): the permittee must report 

the actual value. 

b. Influent or effluent value less than the MDL: the permittee must report “less than 

{numeric MDL}” on the DMR, but use one-half the MDL when calculating the 

net value. 

c. Both influent and effluent values less than the MDL: the permittee must report 

“less than {numeric MDL}” on the DMR, but use one-half the MDL calculating 

for calculating monthly averages.

Flow Measurement Methods 

Approved by Idaho Department of Water Resources1 

The source and means of diversion of water, whether surface or ground water, generally 

determines the measurement and reporting process. Surface water sources such as streams, 

springs and waste channels are normally diverted into open channels (ditches or canals), but 

closed conduits (pipes or culverts) are also used. Ground water is usually diverted into pipes 

(which may also discharge into open channels). 

Measuring devices are required at or near the point of diversion form the public water source. 

SURFACE WATER DIVERSIONS 

I. Flow Measurement 

The following discussion is applicable only to diversions from surface water sources. 

Measurement of a ground water diversion with an open channel measuring device must be preapproved by the Department. 

A. Standard Open Channel Measuring Devices 

All open channel flow diversions should be measured using one of the following standard 

open channel flow measuring devices commonly used in Idaho: 

• contracted rectangular weir 

• suppressed rectangular weir 

• cipolletti weir 

• 90 degree V-notch weir 

• ramped broad crested weir (or ramped flume) 

• parshall flume 

• trapezoidal flume 

• submerged rectangular orifice 

• constant head orifice 

Construction and installation of these devices should follow published guidelines. References 

are available upon request. 

B. Non-standard open channel devices: Rated Structures or Rated Sections 

IDWR may authorize the use of non-standard devices and rated sections provided the 

device or section is rated or calibrated against a set of flow measurements using an 

acceptable open channel current meter or a standard portable measuring device. Further 

restrictions and requirements are available from the Department upon request. 
Permit No.: IDG-130000 

Page 80 of 96 

C. Closed conduit measuring devices 

Refer to the Ground Water measuring section for installation, accuracy, and calibration 

standards of closed conduit measuring devices. 

II. Reporting 

All surface water measuring devices, rated structures and rated sections should be read and 

readings recorded at least once per week, and more frequently if necessary. IDWR will 

accept the assumption of constant flow rates between readings if flow rates are continuous 

and reasonable constant. Forms will be provided for recording dates, stage (or water levels) 

and flow rates. 

Users with diversions located within water districts may report their diversions individually to 

IDWR or provide for the water district water master to report their diversions in acceptable 

annual water distribution reports. Ground water diversions are not normally included in a 

water district, and must be reported individually.
