Background Information
Introduction
The Grandview Trunkline is a major part of the City of Twin Falls' (City's) sewage collection system
and has historically had citizen complaints due to odor. The concrete manholes, cast-iron frames
and lids along the trunk are also in in varying states of decay due to corrosion. The Grandview
Trunkline stretches over 5 miles from the canyon edge along Canyon Rim Road, Grandview Drive,
Filer Avenue, cross-country past the County West building, down into Rock Creek and south along
Washington Street.
This study included collection system sampling, both liquid and vapor phase,to help delineate and
quantify problems areas along the trunkline. This study is the first phase of a project to control
odor and corrosion in the Grandview Trunkline. Subsequent phases will include additional
sampling (if needed), development of solution alternatives and associated capital and life cycle
costs, design of the selected alternative, and bidding and construction phase support.
Collection System Odors and Corrosion
All collections systems naturally create and contain odorous compounds. Various organic and
inorganic compounds are known to cause odors in domestic wastewater collection systems.
Mercaptans, ammonia compounds and various volatile organic compounds are contributors to
most odors found in collection systems. However, hydrogen sulfide is typically the predominant
compound of concern due to its low odor threshold and the associated corrosion from the
conversion of hydrogen sulfide gas to sulfuric acid in the moist head space of gravity sewer lines.

Hydrogen Sulfide Production and Release
The presence of hydrogen sulfide in municipal wastewater is principally the result of
bacteriological reduction of sulfate in the presence of organic matter. Sulfate-reducing bacteria
grow in a "slime layer"that coats the sewer's wetted perimeter(Figure 1).These bacteria consume
the available organic matter with the aid of oxygen in the most readily available form (in order of
preference):
1. Elemental Oxygen
2. Nitrate Oxygen
3. Sulfate Oxygen

Since nitrate is usually not available in wastewater, bacteria will consume sulfate oxygen after
depleting elemental oxygen, leaving bi-sulfide ions to combine with hydrogen to form aqueous
hydrogen sulfide. How quickly sulfide is produced by the slime layer and how it is then released to
the gas phase (creating odor and corrosion problems) is impacted by a number of environmental
factors as briefly described below.

Organic Matter& Sulfate Concentration
Both organic matter and sulfate are prevalent in typical municipal wastewater. By using sulfate as
an oxygen source, sulfate reducing bacteria are able to consume the readily available organic
matter (food) to survive and grow. As such, the hydrogen sulfide production potential of a
municipal wastewater typically increases proportional to the wastewater strength.
Dissolved Oxygen
As mentioned earlier, sewer bacteria prefer elemental oxygen when it's available. At dissolved
oxygen (DO) concentrations above 0.5 to 1.0 mg/L there is typically sufficient oxygen that sulfate
reduction by bacteria is typically eliminated. At this DO concentration, the aerobic portion of the
slime layer is able to grow and thus increases the distance which organic matter and sulfate must
diffuse through the slime to reach the sulfate reducers in the interior anaerobic zone (see Figure
1 for reference). If organic matter and sulfate do happen to reach the anaerobic zone and produce
sulfide, both the exterior aerobic slime layer and the DO rich wastewater stream will oxidize it,
further decreasing the likelihood of aqueous hydrogen sulfide production.
Wastewater gains oxygen in a collection system through re-aeration at the air to water interface.
Turbulence resulting from high velocity flows,junctions, drops, hydraulic jumps and other places
where the air and wastewater aggressively mix increases the reaeration rate. However, turbulent
areas in a collection system do more than just increase the DO level. At these areas, the gaseous
release of pre-existing hydrogen sulfide in the wastewater flow is accelerated as well.
Detention Time
The oxygen consumed by wastewater increases along with its detention time in sewers, force
mains and non-aerated holding basins. This leads not only to decreased oxygen levels, but to
increased availability of the organic matter, further accelerating the oxygen depletion.
Both conditions favor the activity of sulfate reducing organisms and the production of sulfides.
Temperature
As temperature increases, so does the activity of microbial life and the amount of hydrogen sulfide
produced by sulfate reducing bacteria. In general, for every 10 degrees Celsius increase in
temperature, the biological activity of bacteria, and of particular interest odorous sewers, sulfate
reducing bacteria, doubles. Typically, this results in markedly higher sulfide production in the
summer than the winter. Additionally, higher temperatures decrease the solubility of the gases in
solution and as a result the gaseous H2S more readily releases.
Depth of Flow& Velocity
As the depth of flow in a sewer increases, so does the surface area available to grow a sulfide
producing slime layer. Flow rate, pipe diameter and slope are all factors that control the depth of
17-2122 Page 3 of 16 Grandview Odor Control Study
March 2018 City of Twin Falls, Idaho
I:\B0I_Projects\17\2122-Twin Falls Grandview Odor\Memo\TM-Fall 2017_3.14.2018.docx
flow and available surface area. Additionally, if the velocity in a sewer line is too low due to over
sizing or inadequate slope, solids deposition in the system will occur. Deposited solids in a sewer
system typically decay anaerobically, increasing the available slime layer surface area and sulfide
production.
The depth of flow for a given size pipe determines the cross-sectional area of the flow, its water
surface area and therefore has an impact on the release of hydrogen sulfide. In general,the higher
the ratio of water surface area to cross sectional area, the more readily hydrogen sulfide is
released to the atmosphere.
Velocity and/or turbulence in a wastewater flow, as mentioned earlier, also increases the gas
transfer from the wastewater to the air above it. As such, turbulent areas in a collection system
will simultaneously release dissolved hydrogen sulfide and capture oxygen from the air.
pH
Sulfate reducing bacteria can survive in a pH range of 5.5 to 9.0. Since, municipal wastewater
typically is within this range, the pH of the wastewater does not have a significant impact on the
production of aqueous hydrogen sulfide. However, depending on the pH of the wastewater, the
form of sulfide it contains can vary dramatically. Since only the unionized form of sulfide (H2S) can
be released from the wastewater solution, pH plays a significant role in collection system odor and
corrosion.
At a pH of 7, the ionized sulfides (HS- and S-) and unionized aqueous hydrogen sulfide (H2S) are
essentially equal (Figure 2). At higher and lower pH, however these proportions quickly change
with lower pH shifting to more aqueous hydrogen sulfide and thereby increasing the rate of
hydrogen sulfide transfer to the gas phase.

Grandview Trunkline
The Grandview Trunkline generally flows from south to north and collects from a large portion of
the City's sewage collection system. Forthe purposes of this study,the Grandview trunkline begins
at manhole C5-160, near the intersection of Washington Street and Highland Avenue, and
continues to manhole 131-28. The pipes in the trunkline are 18- to 48-inch in diameter and there
are approximately one hundred manholes along the trunk. The Grandview Trunkline is shown in
Figure 3 and as a schematic in Figure 4, both figures are at the end of the memorandum. The City
does not routinely inspect or clean the trunkline because flows and velocity hare high enough that
solids deposition has not historically been a problem.
Rock Creek Lift Station
The City's Rock Creek Lift Station is located one third of the way down the trunkline.The lift station
pumps sewage from an area down in the Rock Creek Drainage up to an area just west of County
West buildings where flows can then proceed by gravity all the way to the WWTP. The lift station
has two separate wet wells. The lift station has seven 50-horsepower vertical coupled pumps each
rated with a design capacity of 2,073 gallon per minute (gpm). Each pump has a pump on and off
setpoint and the pumps are each outfitted with a variable frequency drive (VFD). The lift station
has been noted in the past as a source of odor, particularly in the summer, and significant amounts
of accumulated floatable grease must be removed from the wet well by operations and
maintenance staff. In the first quarter of 2017, the average flow pumped by the lift station was
3,435 gpm (approximately 5 mgd).

Industrial Wastewater Dischargers along the Grandview Trunkline
There are four permitted wastewater dischargers in the southern portion of the Grandview
Trunkline: Glanbia Foods Inc., Lamb Weston Inc., AmeriPride Linen and Apparel Services and
Kapstone Container Corporation. Each of the industrial discharge permits is included in Appendix
1 and is summarized in Table 1 through 4 with actual 2017 quantities for comparison. The location
of the industrial dischargers are also shown on Figure 3 and Figure 4.
Glanbia
Glanbia Foods is a dairy processing facility and discharges its wastewater to the collection system
between Diamond and Washington Street (just north of Glanbia facility). The flow from Glanbia
Food ultimately joins the Grandview Trunk at manhole C5-30. Glanbia does not have a
pretreatment system but does have an equalization basin that it uses at times to keep within their
discharge permit. The 2017 Glanbia wastewater had a high BOD5 concentration, TSS
concentration, relatively high pH and at times high levels of fats/oils/grease (FOG). Glanbia's
wastewater discharge represents approximately 13 percent of the BOD and 7 percent of the
wastewater flow that the wastewater treatment plant (WWTP) treated on average through
calendar year 2017.

AmeriPride Linen and Apparel Services
AmeriPride Linen and Apparel Services discharges to the collection system near 5th Street West
and 2nd Ave West, which is a considerable distance away from the Grandview Trunks. The flow
from this discharger ultimately enters the Grandview Trunk at manhole 134-1. AmeriPride does
utilize a dissolved air floatation thickener process to pretreat its wastewater prior to discharge.

Vapor Phase Odor Monitoring
Equipment and Methods
Murraysmith used eight rented and one City-owned App Tek International OdaLog L2 loggers
(odalogger) odor meters for this study. Murraysmith staff, with assistance from City staff, installed
the flow meters and removed them at the end of the monitoring period. Murraysmith inspected
the meters intermittently to check battery status, download the data, and confirm that the
equipment was operating properly. The odalogger meters were installed on November 20, 2017
and removed on December 12, 2017. The locations where the odaloggers were placed is shown
in Figure 3, at the end of this memorandum, and schematically on Figure 4.
Vapor Phase Results
Table 6 summarizes the data from the individual odaloggers which were suspended from manhole
lids. The odaloggers monitor hydrogen sulfide (H2S) gas concentration and temperature of the
headspace in the collection system. Appendix 2 graphically shows the odalogger data. During the
study, Lamb Weston shut down its operations from November 22 to November 27 for a seasonal
shutdown.The shutdown started with a two-shift cleanup procedure.The change in the odalogger
data caused by the shutdown is evident in the graphs.

Liquid Phase Odor Monitoring
Equipment and Methods
Murraysmith collected liquid wastewater samples on December 7, 2017 taken throughout the day
along the Grandview Trunk. The vapor phase monitoring locations were sampled as well as the
Glanbia discharge, Lamb Weston Discharge #1 (Upstream discharge at manhole C5-2), Lamb
Weston Discharge #2 (Downstream discharge at manhole C4-322), and New Manhole upstream
of manhole C5-2 which is just upstream of Lamb Weston Discharge #1.
The samples were tested for Total Sulfide (mg/L) and Dissolved Sulfide (mg/L) using LaMotte field
test kits (Standard Methods 4500-S2-D Methylene Blue). A Horiba U-52 portable meter with U-
52NISTtested for the following:
■ Temperature— °F
■ pH — unitless
■ Oxidative Reduction Potential —ORPmV
■ Electrical Conductivity— mS/cm
■ Turbidity— NTU
■ Dissolved Oxygen — mg/L
■ Total Dissolved Solids—g/L
■ Salinity— ppt
■ Specific Gravity— unitless
Liquid Phase Results
Table 7 summarizes the results of the sampling. In general, the sulfide concentration is higher in
the upstream portion of the Grandview Trunkline in the area of S1. It also was detected
downstream of the Rock Creek Lift Station. This could be due to generation of sulfide in the lift
station wet well which then is passed further downstream when the lift station operates. After
reviewing the vapor phase odalog data and the liquid phase testing result, the liquid phase testing
was completed during a time of lower collection system vapor H2S levels and the concentration of
liquid phase sulfide would likely have been much greater if sampling occurred during peak vapor
phase H2S concentrations. The highest concentration of sulfides in the Grandview Trunk are likely
much higher than tested during this study. The sampling also showed the wastewater in the
Grandview Trunk is very warm beginning at S2 and continuing downstream. The presence of
negative ORP and dissolved oxygen was unexpected. Typically, the presence of dissolved oxygen
corresponds to ORP of greater than 50 mL ORP. Due to the complexity and difficulty of measuring
DO in field conditions, the ORP is likely the plausible data. At the negative ORP values observed,
typical microbiological reactions such as sulfide formation, acid formation (fermentation) and
methane production can occur. The sulfide concentration and pH of the sample at the new
manhole upstream of Lamb Weston Discharge #1 is quite high which causes sulfide to remain in
solution. But, as the wastewater mixes with more wastewater further down the trunk, the pH will
decrease and sulfides can more readily come out of solution.

As seen in the Table 7, the Glanbia discharge is very high in turbidity, TDS, salinity, and specific
gravity. It also had a particular and very strong odor and detectable sulfide. Glanbia also discharges
a strong waste stream as summarized in Table 2.
Lamb Weston Discharge #1 was noted to have a strong odor and detectable sulfide.
Lamb Weston Discharge #2 is very warm and had a positive oxidative reduction potential. The
sample taken did not have any detectable sulfides. The visual observation of this sample noted
that it had black flecks and white floating material in the sample.

Monitoring Site Condition Observation
During the monitoring, condition information for each site was also recorded and is summarized
below. Pictures of each site are also included in Appendix 3.
Site SO is just off of Washington Street and is upstream of all of the permitted wastewater
dischargers. This manhole is in good condition, with no smell and appeared to have negative
pressure pulling air into the collection system during onsite investigations.
Site S1 is down in the rock creek drainage and is a new manhole that was installed in late-summer
of 2017. No smell was perceived coming out the manhole and there was negative pressure pulling
outside air into the manhole.
Site S2 is a manhole in the rock creek drainage that was wet, slimy, and had corrosion.
Site S3 is a manhole that was very wet with a thick slime layer growing and covering much of the
manhole. The concrete in the manhole is in bad condition and the lid and frame are badly
corroded. This site was very odorous and could be smelled 20-feet away while approaching the
manhole.
Site S4 is the discharge manhole of the force main from Rock Creek Lift Station. The manhole was
wet, had little to no smell and possibly had negative air pressure. The wire mesh reinforcing is
visible through the concrete due to corrosion.
Site S5 is manhole with two large diameter pipes entering the manhole. The concrete in the
manhole is in bad condition. During investigations, the manhole was under negative pressure and
little smell was observed.
The manhole at Site S6 is in very bad condition and smelled with positive pressure pushing air out
of the collection system.
Site S7 is a manhole with concrete in bad condition. However, there was no smell coming out of
the manhole because it was under negative pressure and pulling air into the collection system.
Site S8 is a square concrete collection box with a stainless-steel double-leaf lid. This site has
corrosion and aggregate is visible with rebar discoloration showing through. The headspace in the
box is under positive pressure and smells.
Conclusions
This study is the beginning of the City's efforts to control odor and corrosion along the Grandview
Trunkline. This study has determined the following conclusions:
■ The Grandview Trunkline sewer has odorous wastewater which can be smelled in
places along the entire alignment without opening manhole lids.

■ Conditions are ripe for generation of odors, H2S, and corrosion of the collection system:
o High concentrations of sulfides in solution.
o Warm wastewater leading to condensation and biofilm growth.
o Poor air movement in areas of collection system: tightly fitting composite
manhole lids, both positive and negative air pressure observed.
■ Severe corrosion exists on manholes, lids and frames along the entire trunkline and is
consistent from the upper areas to the lower areas of the trunkline.
■ Manholes need to be repaired, rehabilitated and replaced.
■ Any non-plastic pipelines are likely is similar condition to manholes and need to be
repaired, rehabilitated and replaced.
Other utilities have started treating wastewater at liquid sulfide concentration of 1 mg/L with the
goal to get concentration below 0.3 mg/L.This study observed sulfide concentration above 4 mg/L
during a time of "low" observed sulfides. Concrete begins degrading with any H2S in headspace
and typical treatment goals are below 5 ppm. This study had as high as 333 ppm observed.
Recommendations
Based on this study, Murraysmith recommends the following future tasks:
■ Progressively Evaluate Hydrogen Sulfide Management Alternatives
o Evaluate Liquid Phase Chemical Treatment Options
■ Evaluate Alternatives for liquid treatment including chemical review.
■ Complete sampling and chemical jar testing of the industrial discharges
to determine optimal dosage of treatment chemicals
o Evaluate Alternatives to Ventilate Trunkline Headspace into an Odor Control
System
■ Liquid Phase Treatment Pilot
o Complete a pilot program and feasibility study of liquid phase treatment at
select locations.
■ Vapor phase treatment at key location of the Grandview Trunkline
o Complete a pilot program and feasibility study of vapor phase treatment of the
Grandview Trunkline.

I:\B0I_Projects\17\2122-Twin Falls Grandview Odor\Memo\TM-Fall 2017_3.14.2018.docx
■ Rock Creek Lift Station FOG Control
o Study and evaluation of the fats, oil and grease control at the Rock Creek Lift
Station which have led to operation/maintenance problems and odor
generation at the lift station in the past.
■ Inspect and assess the corrosion damage to both pipe and manholes along the
Grandview Trunkline
o Pipeline condition assessment — Confirm pipe material, size, and age at a
minimum.
o Manhole condition assessment—Confirm material, size and age at a minimum.
o Program should include repair, rehabilitation and replacement alternatives
analysis.
o Program should include sewer infrastructure prioritization of repair,
rehabilitation and replacement.

permittee shall contact the City of Twin Falls for assistance.This notification shall occur
at least 90 days prior to the proposed change.
• Formal written notification shall be made at least ten(10) days prior to such introduction
and the permittee shall obtain approval from the City to do so.
F. UPSET
1. Definition
For the purpose of this section, "Upset"means an exceptional incident in which there is
unintentional and temporary non-compliance with applicable pretreatment standards
because of factors beyond the reasonable control of the permittee. An upset does not
include non-compliance to the extent caused by operational error, improperly designed
treatment facilities, inadequate treatment facilities, lack of preventive maintenance,
careless and/or improper operation.
2. Conditions Necessary for a Demonstration of Upset
An upset shall constitute an affirmative defense to an action brought for noncompliance
with applicable pretreatment standards if the requirements of Part 3 Section E are met.
A permittee who wishes to establish the affirmative defense of an upset shall
demonstrate,through properly signed, contemporaneous operation logs or other relevant
evidence,that:
a. An upset occurred and the permittee can identify the specific cause(s)of the
upset;
b. The facility was, at the time, being operated in a prudent and workman-like
manner and in compliance with applicable operation and maintenance procedures;
and
c. The permittee has submitted the following information to the City of Twin Falls
within 24 hours of becoming aware of the upset(if this information is provided
verbally,a written submission must be provided with five working days):

H. HAZARDOUS WASTE NOTIFICATION
1. Any user who commences the discharge of hazardous waste shall notify in writing: the
City of Twin Falls, EPA region 10 office of air,waste, and toxics director, and the Idaho
department of health and welfare,division of environmental quality remediation section,
of any discharge into the city's sewage collection system of a substance which, if
otherwise disposed of,would be a hazardous waste under 40 CFR part 261. Such
notifications to the City of Twin Falls shall be made within the appropriate time frames
specified in the City of Twin Falls Municipal Code 7-7-4, whichever is shorter. The
notification requirements of this section do not apply to pollutants already reported by
industrial users under self-monitoring requirements of this chapter.
Such notification shall include:
1. The name of the hazardous waste as set forth in 40 CFR part 261;
2. The EPA hazardous waste number; and
12
3. The type of discharge(continuous, batch,or other).
4. If an industrial user discharges more than one hundred (100)kilograms of such waste
per calendar month to the sewer system,the notification shall also contain the
following information to the extent it is known or readily available to the industrial
user:
(a)An identification of the hazardous constituents contained in the wastes;
(b)An estimation of the mass and concentration of such constituents in the waste
stream(s)discharged during that calendar month; and
(c)An estimation of the mass of constituents in the waste stream(s)expected to be
discharged during the following twelve (12)months.
All notifications must take place no later than one hundred eighty(180)days after the
discharge(s)commences. Any notification under this subsection need be submitted
only once for each hazardous waste discharged.However,notifications of changed
conditions must be submitted under this chapter.
2. Dischargers are exempt from the requirements of subsection(A)of this section during a
calendar month in which they discharge no more than fifteen(IS)kilograms of hazardous
wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d)
and 261.33(e). Discharge of more than fifteen (15) kilograms of no acute hazardous
wastes in a calendar month,or of any quantity of acute hazardous wastes as specified in
40 CFR 261.30(d)and 261.33(e), requires a onetime notification. Subsequent months
during which an industrial user discharges more than such quantities of any hazardous
waste do not require additional notification.

PART 6 BYPASS OF TREATMENT FACILITIES
A. Definitions
"Bypass" means the intentional diversion of waste-streams from any portion a
Permittee's treatment facility.
"Severe Property Damage" means substantial physical damage to property,
damage to the treatment facilities which causes them to become inoperable, or
substantial and permanent loss of natural resources which 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. (cf. 403.17(a) (2))
B. Bypass Not Violating Applicable Pretreatment Standards
The Permittee may allow any bypass to occur which does not cause applicable
pretreatment standards or requirements to be violated, but only if it also is for
essential maintenance to assure efficient operation. These bypasses are not
subject to the provision of Paragraphs C. and D. of this section.
C. Bypass Notifications
i. If the Permittee knows in advance of the need for a bypass, it shall submit
prior notice, to the POTW at least ten (1o) days before the date of the
bypass, if possible.
2. The Permittee shall submit oral notice to the City of an unanticipated
bypass that exceeds applicable pretreatment standards within twenty four
(24) hours from the time the Permittee becomes aware of the bypass. A
written submission shall also be provided within five (5) days of the time,
the Permittee becomes aware of the bypass. The written submission shall
contain a description of the bypass and its cause; the duration of the
bypass, including exact dates and times, and, if the bypass has not been
corrected, the anticipated time it is expected to continue; and steps taken or
planned to reduce, eliminate and prevent recurrence of the bypass. The
City may waive the written report on a case-by-case basis if the oral report
has been received within twenty four(24)hours.
D. Bypass Prohibition and Conditions
Bypass is prohibited, and the City may take an enforcement action against the
Permittee for a bypass, unless:
i. Bypass is 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 backup 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 preventative

7. A "Grab" sample is a sample which is taken from a waste stream on a one-time basis without
regard to the flow in the waste stream and without consideration of time. Grab samples must
be used for pH (unless performing continuous pH monitoring), cyanide, and oil and grease.
For all other pollutants, twenty-four(24)-hour composite samples must be obtained through
flow-proportional composite sampling techniques, unless time-proportional composite
sampling or grab sampling is authorized by the Control Authority, the samples must be
representative of the discharge and the decision to allow alternative sampling must be
documented in the in the user file. Using protocols (including appropriate preservation)
specified in 40 CFR 136 and appropriate EPA guidance, multiple grab samples collected
during the 24-hour period may be composited prior to the analysis as follows: for cyanide the
samples may be composited in the laboratory. Composite samples for other parameters
unaffected by compositing procedures as documented in approved EPA methodologies may
be authorized by the Control Authority, as appropriate. A minimum of 1 grab sample shall
be collected every 2 hours of operation; in no case shall less than 4 samples be collected.

treatment facilities, inadequate treatment facilities, lack of preventive maintenance,
careless and/or improper operation.
2. Conditions Necessary for a Demonstration of Upset
An upset shall constitute an affirmative defense to an action brought for noncompliance
with applicable pretreatment standards if the requirements of Part 3 Section E are met.
A permittee who wishes to establish the affirmative defense of an upset shall
demonstrate, through properly signed, contemporaneous operation logs or other relevant
evidence, that:
10
a. An upset occurred and the permittee can identify the specific cause(s) of the
upset;
b. The facility was, at the time,being operated in a prudent and workman-like
manner and in compliance with applicable operation and maintenance procedures;
and
c. The permittee has submitted the following information to the City of Twin Falls
within 24 hours of becoming aware of the upset(if this information is provided
verbally, a written submission must be provided with five working days):
(1) A description of the indirect discharge and cause of non-compliance.
(2) The period of non-compliance, including exact dates and times, or if not
corrected, the anticipated time the noncompliance is expected to continue.
(3) Steps being taken and/or planned to reduce, eliminate, or prevent recurrence
of the noncompliance.
3. Burden of Proof
In any enforcement proceeding the permittee seeking to establish the occurrence of an
upset shall have the burden of proof.
4. Permittee Responsibility in Case of Upset
The permittee shall control production and all discharges to the extent necessary to
maintain compliance with applicable pretreatment standards upon reduction, loss, or
failure of its treatment facility until the facility is restored or an alternative method of
treatment is provided. This requirement applies in the situation where, among other
things, the primary source of power of the treatment facility is reduced, lost or fails.
5. 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.
F. NOTIFICATION OF SIGNIFICANT PRODUCTION CHANGE
Any permittee operating under permit incorporating equivalent mass or concentration limits shall
notify the city within two (2)business days after the user has a reasonable basis to know that the
production level will significantly change within the next calendar month. Any user not
providing a notice of such anticipated change will be required to comply with the existing limits
contained in its industrial wastewater discharge permit.
11
G. HAZARDOUS WASTE NOTIFICATION
1. Any user who commences the discharge of hazardous waste shall notify in writing: the
City of Twin Falls, EPA region 10 office of air, waste, and toxics director, and the Idaho
department of health and welfare, division of environmental quality remediation section,
of any discharge into the city's sewage collection system of a substance which, if
otherwise disposed of, would be a hazardous waste under 40 CFR part 261. Such
notifications to the City of Twin Falls shall be made within the appropriate time frames
specified in the City of Twin Falls Municipal Code 7-7-4,whichever is shorter. The
notification requirements of this section do not apply to pollutants already reported by
industrial users under self-monitoring requirements of this chapter.
Such notification shall include:
1. The name of the hazardous waste asset forth in 40 CFR part 261;
2. The EPA hazardous waste number; and
3. The type of discharge (continuous, batch, or other).
4. If an industrial user discharges more than one hundred(100) kilograms of such waste
per calendar month to the sewer system, the notification shall also contain the
following information to the extent it is known or readily available to the industrial
user:
(a)An identification of the hazardous constituents contained in the wastes;
(b)An estimation of the mass and concentration of such constituents in the waste
stream(s) discharged during that calendar month; and
(c) An estimation of the mass of constituents in the waste stream(s) expected to be
discharged during the following twelve (12) months.
All notifications must take place no later than one hundred eighty(180) days after the
discharge(s) commences. Any notification under this subsection need be submitted
only once for each hazardous waste discharged. However, notifications of changed
conditions must be submitted under this chapter.
2. Dischargers are exempt from the requirements of subsection (A) of this section during a
calendar month in which they discharge no more than fifteen (15)kilograms of hazardous
wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d)
and 261.33(e). Discharge of more than fifteen (15) kilograms of no acute hazardous
wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in
40 CFR 261.30(d) and 261.33(e), requires a onetime notification. Subsequent months
during which an industrial user discharges more than such quantities of any hazardous
waste do not require additional notification.
12
3. In the case of any new regulations under section 3001 of RCRA identifying additional
characteristics of hazardous waste or listing any additional substance as a hazardous
waste, an industrial user shall notify the city, the EPA region 10 office of air, waste, and
toxics director, and the Idaho department of health and welfare, division of environmental
quality remediation section, of the discharge of such substance within ninety (90) days of
the effective date of such regulations.
4. In the case of any notification made under this section, an industrial user shall certify that
it has a program in place to reduce the volume and toxicity of hazardous wastes generated
to the degree it has determined to be economically practical.
5. This provision does not create a right to discharge any substance not otherwise permitted
to be discharged by this chapter, a permit issued hereunder, or any applicable federal or
state law.

a. Bypass is prohibited, and the city may take enforcement action against the permittee
for a bypass,unless:
1. Bypass 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
backup equipment should have been installed in the exercise of reasonable
engineering judgment to prevent a bypass, which occurred during normal
equipment downtime or preventative maintenance.
3. The permittee submitted notices as required under paragraph C of this section.

contained in its industrial wastewater discharge permit.
G. HAZARDOUS WASTE NOTIFICATION
1. Any user who commences the discharge of hazardous waste shall notify in writing: the
City of Twin Falls, EPA region 10 office of air, waste, and toxics director, and the Idaho
department of health and welfare, division of environmental quality remediation section,
of any discharge into the city's sewage collection system of a substance which, if
otherwise disposed of, would be a hazardous waste under 40 CFR part 261. Such
notifications to the City of Twin Falls shall be made within the appropriate time frames
specified in the City of Twin Falls Municipal Code 7-7-4, whichever is shorter. The
notification requirements of this section do not apply to pollutants already reported by
industrial users under self-monitoring requirements of this chapter.
Such notification shall include:
1. The name of the hazardous waste as set forth in 40 CFR part 261;
2. The EPA hazardous waste number; and
3. The type of discharge (continuous, batch, or other).

L. LIMITATION OF PERMIT TRANSFER
Industrial wastewater discharge permits may be reassigned or transferred to a new owner and/or
operator only if the permittee gives at least 30 days advance notice to the City and the City
approves the industrial wastewater discharge permit transfer. The notice to the City must include
a written certification by the new owner and/or operator which:
1. States that the new owner and/or operator has no immediate intent to change the facility's
operations and processes;
2. Identifies the specific date on which the transfer is to occur; and
3. Assumes full responsibility for complying with the existing industrial wastewater
discharge permit beginning on the date of transfer.
Failure to provide advance notice of a transfer renders the wastewater discharge permit voidable
as of the date of facility transfer.
Provided that the above occurs and that there were no significant changes to the manufacturing
operation of wastewater discharge, the new owner will be considered and existing user and be
covered by the existing limits and requirements in the previous owner's permit.
M. MONITORING FACILITES
Each industrial user shall provide and operate at its own expense a monitoring facility to allow
inspection, sampling and flow measurement of each sewer discharge to the City. Each
monitoring facility shall be situated on the user's premises except, where such a location would
be impractical or cause undue hardship on the user, the City may concur with the facility being
constructed in another area, providing that the facility is located so that it will not be obstructed.
The City, whenever applicable, may require the construction and maintenance of sampling
facilities at other location(for example, at the end of a manufacturing line, wastewater treatment
system, etc.).
There shall be ample room in or near sampling facilities to allow accurate sampling and
preparation of samples for analysis. Sampling Facilities, including sampling and measuring
equipment, shall be maintained at all times in a safe and proper operating condition at the user's
expense.
The City may require the user to install monitoring equipment as necessary. All monitoring
facilities shall be constructed and maintained in accordance with all applicable City construction
standards and specifications. All devices used to measure wastewater flow and quality shall be
calibrated at a frequency that will ensure their continuous accuracy.
20
N. FALSIFYING INFORMATION OR TAMPERING WITH MONITORING EQUIPMENT
Knowingly making any false statement on any report or other document required by the permit
or knowingly rendering any monitoring device or method inaccurate may result in punishment
under criminal laws of the City, as well as being subjected to civil penalties. In addition the
industrial user shall be subject to:
1. The provisions of 18 U.S.C. Section 1001 relation to fraud and false statements.
2. The provisions of Sections 309 (c)(4) of the Clean Water Act, as amended governing

Coordinator or authorized representative, any noncompliance resulting from the emergency
situation.
T. FLOW MEASUREMENT
The appropriate flow measurement devices and methods consistent with approved scientific
practices shall be selected and used to ensure the accuracy and reliability of measurements of the
volume of monitored discharges. The devices shall be installed, calibrated and maintained to
ensure that the accuracy of the measurements are consistent with the accepted capability of that
type of device. Devices selected shall be capable of measuring flows with a maximum deviation
of less than ten percent from true discharge rates throughout the range of expected discharge
volumes

substantial and permanent loss of natural resources which 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.
2. Bypass Not Violating Applicable Pretreatment Standards or Requirements
The permittee may allow any bypass to occur which does not cause applicable pretreatment
standards or requirements to be violated, but only if it is for essential maintenance to assure
efficient operation. These Bypasses are not subject to the provision of Paragraphs 3 and 4 of this
section.
22
3. Notice of Bypass
a. If the permittee knows in advance of the need for a bypass, it shall submit prior
notice to the City, if possible, at least five days before the date of the bypass.
b. The permittee shall submit oral notice of unanticipated bypass that exceed
applicable pretreatment standards to the City within 24 hours from the time the
permittee becomes aware of the bypass. A written submission shall also be
provided within two days of the time the permittee becomes aware of the bypass.
The written submission shall contain a description of the bypass, it's' cause, the
duration of the bypass, including exact dates and times. If the bypass has not
been corrected, the submission shall also include the anticipated time it is
expected to continue; and steps taken or planned to reduce, eliminate and prevent
recurrence of the bypass. The City may waive the written report on a case-by-
case basis if the oral report has been received within 24 hours.
4. Prohibition of Bypass
a. Bypass is prohibited, and the city may take enforcement action against the permittee
for a bypass,unless:
1. Bypass 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
backup equipment should have been installed in the exercise of reasonable
engineering judgment to prevent a bypass, which occurred during normal
equipment downtime or preventative maintenance.
3. The permittee submitted notices as required under paragraph C of this section.
b. The City shall have the right to approve an anticipated bypass, after being given time
to consider its' adverse effects, if the City determines that it will meet the three
