Any permittee authorized by this general permit may request to be excluded from the coverage of the general permit by a pplying for an individual permit. The permittee shall submit an individual permit application with reasons supporting the request to EPA no later than 90 days af ter 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 faci lity or collected in a raceway or settling basin or held in stor age, 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 covera ge. If a permittee whose authorization to discharge has been terminated or inactivat ed under §§1 or 2 below wants to resume operation, it must request aut horization in writing from EP A 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 cessa tion of operation or permanent change in operation that reduces the pr oduction 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 wa ter 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 author ized to discharge pollutants from the outfall(s) specified in its NOI within the limits and subjec t to the conditions set forth in this permit. This permit authorizes the discharge of only those pollutants resulting from facilityPermit No.: IDG-130000 Page 10 of 96 processes, waste streams, and operations that ha ve 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 spil ls and other unintentional or nonroutine discharges of pollutants, that are not part of the norma l operation of the facility as disclosed in the permittee’s NOI, nor does it authori ze the discharge of any pollutants that are not ordinarily present in such waste streams.
A. Effluent Limitations The permittee must limit discharges from a ll 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 fre quency 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 discharg e of a pollutant a bove the alternate technology-based limit applicable to the f acility for raceways and full-flow settling basin discharges; see Table 1 for total phos phorus trading limits, as an example. No trading is allowed to adjust discha rges to meet maximum daily limits. See Appendix C for details about the requiremen ts 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 a nd full-flow settling basin discharges, which provide the upper limit on buying phosph orus 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 not ed in Tables 2 and 3 by footnotes on these facilities.1 Permit No.: IDG-130000 Page 11 of 96

Table 1 

### Upper Limit for Buyers of Total Phosphorus Credits Type of Facility Average Monthly Limitations Cold Water Facilities 0.10 mg/l
Warm Water Facilities:

FBI Catfish Farm 1 15.4 lbs/day (Mar – Aug)
First Ascent 7.8 lbs/day
FBI Catfish may only buy credits up to this limit betwee n March and August, inclusive. For the rest of the year, a technology-based average monthly limit for total phospho rus applies and precludes buy ing 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 fac ilities also have seasonally variable limits which are listed in Table 3. For limitations on facilities on Billingsley Creek, see Table 4.

Total Suspended Solids 67 mg/l 12 100 mg/l 12 & ≥ 90% removal

12 Limit is Net: OLSB effluent – facility influent 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 discharg e to waters of the U.S.:

a. Any floating solids or visible foam in ot her than trace amounts on the surface of the receiving water; b. Any hazardous materials in concentra tions found to be of public health significance or to impair de signated beneficial uses;

c. Any sludge, grit and accumul ated solid residues; d. Any untreated cleaning wastewater (e.g., obtained from a vacuum or standpipe bottom drain system or rearing/ holding unit disi nfection); or

e. Any floating, suspended or submerged ma tter, including dead fish, in amounts causing nuisance or objec tionable condition or that may impair designated beneficial uses in the receiving water. f. Any toxic substances, including drugs, pe sticides, 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 concentr ations 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 boar ds 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 hol ding 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 Depart ment of Fish and Game for importation, transportation or release or sale or export for such sp ecies, 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 efflue nt values are less than the MDL, thepermittee 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 samp les 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 com posite sample must be analyzed. b. Location. The permittee must collect efflue nt samples from the effluent stream just prior to discharge into the receivi ng waters or, if it mixes with other flows prior to discharge, just before the su bsequent mixing with other flows. For facilities with raceway(s) discharging to a full-flow settling basin(s), the permittee must collect effluent samples fr om the full-flow settling basin(s) just prior to discharge into the receiving waters.

c. Small discharges. Facilities with small di scharges that comprise less than 1% of the total raceway flows are not require d to monitor these discharges for pollutant quality as long as the effl uent quality of these discharges is substantially identical to monitored discharges from the facility, and the permittee provides in its Quality Assuran ce Plan the justification for excluding such discharges from its routine e ffluent pollutant monitoring. Such justification must address the reason the effluent quali ty is expected to bePermit No.: IDG-130000 Page 31 of 96 identical to the monitored outfall and th e 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 us ed in calculating facility pollutant loads.

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, begi nning in the first full calendar quarter after the permit’s effective date. For facilities that produce less than 100,00 0 pounds of harvestable weight of fish per year, this monitoring is only required twice per calendar year, once in January – June an d once in July – D ecember, 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 pointsPermit 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 require d for discharges from warm-water facilities

. 21 Only when using chelated coppe r 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 n itrogen plus nitrate and n itrite) is required only for Springfield Hatchery.
4. Off-Line Settling Basin Additional Limita tions. These limitations and monitoring requirements apply to any disc harge 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 di scharge into the receiving waters..

Notes continue on next page.

25 Offline settling basin influent and effluent samples must be collected during quiescent zone cleaning. 26 Monitoring must begin in the first full calendar month of permit coverage. 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, begi nning in the first full calendar quarter after the permit’s effective date. For facilities that produce less than 100,00 0 pounds of harvestable weight of fish per year, this monitoring is only required twice per calendar year, once in January – June an d once in July – D ecember, 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, samp le results may be averaged when calculating the average monthly concentration and load. Facilities using spring wa ter 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 an alysis 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 th at discharge directly to receiving water must conduct receiving water monitori ng 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 imme diately 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 re quired MDLs. Such a request must be in writing and must be approve d by EPA before the permittee may use the revised MDLs. 5. Receiving water monitoring may be conducte d jointly with nearby dischargers in cases where the background (upstream) m onitoring would be located in similar locations, e.g. where both discharge into th e same lake. Such discharge locations must be chosen in consultation with IDEQ and EPA and be documented in eachPermit 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.

# Upper Snake Rock Watershed
Pollutant TradingPermit No.: IDG-130000 Page 70 of 96Permit No.: IDG-130000 Page 71 of 96 

### 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-po int sources in this watershed, pur suant to the requirements in Idaho = s Water Quality Pollutant Trading Guidance 2003, Upper Snake Rock Watershed Management Plan, Modification, August 2005; a nd the conditions contained within this general permit. No permittee may buy credits that increase its aver age monthly discharge above its applicab le technology-based total phosphorus limit. 

### I. How to Buy Cred its for Pollutant Trading A facility may purchase available phosphorus cr edits (in lbs/day for a specified month) from a point or nonpoint s ource using the Trade Tracking System operated by the Idaho Clean Water Cooperati ve to officially record the credit transaction. Acquiring such cr edits 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 subtrac ting the amount of purchased credits from its actual discharge amount. The purch ased credits are used to modify the actual average monthly phosphorus discha rge rather than increase the limit because EPA’s system to track informa tion reported on the DMR is not able to show how credit transactions adjust a pe rmit limit. Therefore, the point source buyer instead must adjust its reported actual discharge for that month by subtracting the credit amount it has acquire d and recorded in the Trade Tracking System. In the case of a point source se ller, it must adjust its reported actual discharge for that month by adding the cr edit amount it has sold and recorded in the Trade Tracking System. 

### II. Timing of Pollutant Trades Credits can only be traded for the ca lendar month in which the credit was generated (for example, the month in wh ich the point source seller decreased its discharge of phosphorus below its averag e monthly limit to establish the amount of the credit). If a credit is acquired by a qualified aquacultur e facility or fish processor, the resulting d ecrease in the buying facility = s reported average monthly phosphorus discharge is applicable only during the month associated with the credit. The purchase of phosphorus credit s 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, th e eligible buyer and se ller must complete a Trade Notification Form, available from th e 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 th e information reported on the TradePermit No.: IDG-130000 Page 72 of 96
Notification Form. 

### IV. Reporting Pollutant Trad es to EPA and IDEQ The permittee shall submit to EPA (with copies to IDEQ) a phosphorus-specific discharge monitoring repor t (DMR) and the Trade Su mmary Report provided by the Idaho Clean Water Cooperative. The Trade Summary Report will provide (A) the permittee’s actual average monthl y 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) sol d, if any; and (D) the permittee’s A adjusted 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 th e actual phosphorus and “adjusted discharge” and must be submitted by the 10 th day of the second month following sampling. If the buyer and seller submit a Trade Notif ication Form to the Idaho Clean Water Cooperative but the credits ar e not available for transfer to the buyer, then the trade is not recorded in the Trade Track ing System and the buyer is subject to noncompliance penalties for any actual disc harge 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 transferre d 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 Coopera tive (or alternatively, IDEQ, if the Cooperative has chosen to not operate th e Trade Tracking System). The Idaho Clean Water Cooperative records all trad es and generates a monthly summary report of all trades valid for each cale ndar 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 10 th 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 occurri ng 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.Permit No.: IDG-130000 Page 73 of 96

# Effluent CalculationsPermit No.: IDG-130000 Page 74 of 96Permit No.: IDG-130000 Page 75 of 96


### 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 mon itoring locations. The net concentration is the difference between the two measurements and can either be positive or negative since the pollutant load may either incr ease or decrease as the water passes through the facility. It is calculated as follows: 

### Effluent concentration (mg/l) – i nfluent 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 reporte d 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 usi ng 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 mgPermit 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

concentrat effluent OLSB -ion concentrat influent OLSB ion × 100 = removal % ion concentrat effluent OLBS


### 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.Permit No.: IDG-130000 Page 77 of 96

# Flow Measurement Methods Approved by Idaho Department of Water ResourcesPermit No.: IDG-130000 Page 78 of 96Permit No.: IDG-130000 Page 79 of 96 

## Flow Measurement Methods Approved by Idaho Department of Water Resources 1

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 culv erts) 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 diversi on 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 devi ces 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 st andard portable measuring device. Further restrictions and requirements are availa ble 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 struct ures 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 betw een 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 distri cts may report their divers ions individually to IDWR or provide for the water district water ma ster to report their di versions in acceptable annual water distribution reports. Ground water diversions are not normally included in a water district, and must be reported individually.
