DESCRIPTION OF FACILITY
The Salem City Water Reclamation Facility (SALEM CITY WRF) is located at approximately 1081 North 1750 West, Salem UT 84653 and serves the City of Salem with the outfall located at latitude
40o4'16" and longitude 111o42'43". The design capacity is 1.5 MGD with a maximum monthly average of 1.8 MGD, population equivalent of 20,000, and influent organic loadings of 200 mg/L
each for BOD5 and TSS. Present flow to the existing lagoons is approximately 1.0 MGD on average and up to a peak hourly flow of 3.2 MGD.
The SALEM CITY WRFconsists of headworks with grit removal, oxidation ditches preforming Biological Nutrient Removal (BNR), secondary clarifiers, chemical phosphorus precipitation, Ultra
Violet disinfection, biosolids dewatering. Tertiary treatment is required to meet Type 1 Reuse requirements. Biosolids are hauled to an offsite facility located at NUERA Bayview Landfill
for disposal.
This SALEM CITY WRFwas being constructed as the existing lagoons are not able to meet the ammonia standards. The change in the ammonia effluent limit was necessitated by a rule change
required by EPA and adopted by the Utah Water Quality Board in October 2008. This rule change extended the chronic ammonia criteria from 3A and 3B waters to include 3C and 3D waters.
The new plant increases the capacity to 1.5 MGD average flow and 4.4 MGD peak hourly flow.
SUMMARY OF CHANGES FROM PREVIOUS PERMIT
The summertime ammonia limits for the permit have decreased slightly. This is due to changes in the effluent pH as reported by the Discharge Monitoring Report Data.
Also, seasonality has been added for Whole Effluent Toxicity testing. The change was made to more accurately represent that seasonal conditions of the receiving water.
The Water Quality Board adopted Utah Administrative Code (UAC) R317-1-3.3, Technology-Based Phosphorus Effluent Limit (TBPEL) Rule in 2014. The TBPEL rule as it relates to "non-lagoon"
wastewater treatment plants establishes new regulations for the discharge of phosphorus to surface waters and is self-implementing. The TBPEL rule includes the following requirements
for non-lagoon wastewater treatment plants:
The TBPEL requires that all non-lagoon wastewater treatment works discharging wastewater to surface waters of the state shall provide treatment processes which will produce effluent
less than or equal to an annual mean of 1.0 mg/L for total phosphorus. This TBPEL shall be achieved by January 1, 2020.
The TBPEL discharging treatment works are required to implement, at a minimum, monthly monitoring of the following beginning July 1, 2015:
R317-1-3.3, D, 1 Influent for total phosphorus (as P) and total Kjeldahl nitrogen (as N) concentrations;
R317-1-3.3, D, 2. Effluent for total phosphorus and orthophosphate (as P), ammonia, nitrate-nitrite and total Kjeldahl nitrogen (an N);
In R317-1-3.3, D, 3 the rule states that all monitoring shall be based on 24-hour composite samples by use of an automatic sampler or a minimum of four grab samples collected a minimum
of two hours apart.
The TBPEL discharging treatment works are required to implement, at a minimum, monthly monitoring of the following beginning July 1, 2015:
R317-1-3.3, E, 1, a. Influent for total phosphorus (as P) and total Kjeldahl nitrogen (as N) concentrations;
R317-1-3.3, E, 1, b. Effluent for total phosphorus and orthophosphate (as P), ammonia, nitrate-nitrite and total Kjeldahl nitrogen (an N);
In R317-1-3.3, E, 3 the rule states that all monitoring shall be based on 24-hour composite samples by use of an automatic sampler or a minimum of four grab samples collected a minimum
of two hours apart.
The phosphorus annual loading cap is defined as
"Annual Loading Cap” is the highest allowable phosphorus loading discharged over a calendar year, calculated as the sum of all the monthly loading discharges measured during a calendar
year divided by the number of monthly discharges measured during that year.
The reported monthly loading is calculated as shown here;The annual total phosphorus loading
DISCHARGE
DESCRIPTION OF DISCHARGE
The facility has one outfall. The City is not currently planning to reuse the effluent during this permit cycle. However, reuse conditions are being included at this time to give the
facility maximum operating flexibility throughout this permit term.
OutfallDescription of Discharge Point
001 Located at latitude 40° 4' 16" and longitude 111° 42' 44". The discharge is to Beer Creek on the west side of the treatment plant.
RECEIVING WATERS AND STREAM CLASSIFICATION
The receiving water for Outfall 001 is Beer Creek, which drains to Benjamin Slough of Utah
Lake.
Per UAC R317-2-13.5.c, the designated beneficial uses for Beer Creek (Utah County) from 4850
West (in NE1/4NE1/4 sec. 36, T.8 S., R.1 E.) to headwaters are 2B, 3C, and 4.
Class 2B -- Protected for infrequent primary contact recreation. Also protected for secondary contact recreation where there is a low likelihood of ingestion of water or a low degree
of bodily contact with the water. Examples include, but are not limited to, wading, hunting, and fishing.
Class 3C -- Protected for nongame fish and other aquatic life, including the necessary aquatic organisms in their food chain.
Class 4 -- Protected for agricultural uses including irrigation of crops and stock watering.
TOTAL MAXIMUM DAILY LOAD (TMDL) REQUIREMENTS

According to the Utah’s 2016 303(d) Water Quality Assessment Report dated December 7, 2016, the receiving water Beer Creek and Utah Lake downstream of the discharge are listed as impaired
for several parameters. No TMDL has been completed for this watershed at this time. As a result, effluent limits will be placed in the permit. These limits will be at the Water Quality
Standard for Total Dissolved Solids. TDS limit will be set to 1,550 mg/L by the wasteload analyis.

BASIS FOR EFFLUENT LIMITATIONS
Limitations on total suspended solids (TSS), biochemical oxygen demand (BOD5), E. coli, pH, and percent removal for BOD5 and TSS are based on current Utah Secondary Treatment Standards,
UAC R317-1-3.2. The phosphorus limit is based on the TBPEL rule UAC R317-1-3.3. The oil and grease limit is based on best professional judgment (BPJ). Attached is a Wasteload Analysis
for this discharge into Beer Creek. The limits for ammonia, Total Residual Chlorine and Dissolved Oxygen are set by the attached wasteload analysis. It has been determined that this
discharge will not cause a violation of water quality standards. An Anti-degradation Level II review was required since this is a new facility. The permittee is expected to be able to
comply with these limitations.
Reasonable Potential Analysis
Since January 1, 2016, DWQ has conducted reasonable potential analysis (RP) on all new and renewal applications received after that date. RP for this permit renewal was conducted following
DWQ’s September 10, 2015 Reasonable Potential Analysis Guidance (RP Guidance). There are four outcomes defined in the RP Guidance: Outcome A, B, C, or D. These Outcomes provide a frame
work for what routine monitoring or effluent limitations are required
A quantitative RP analysis was performed on the following metalsto determine if there was reasonable potential for the discharge to exceed the applicable water quality standards: Total
Arsenic, Total Cadmium, Total Chromium, Total Copper, Total Lead, Total Molybdenum, Total Nickel, Total Selenium, Total Silver, Total Zinc and Total Mercury. Based on the RP analysis,
none of the metals exceeded the most stringent chronic water quality standard or were determined to have a reasonable potential to exceed the standards. AS a result, there will be no
specific metals limits in the permit. A copy of the RP analysis is included at the end of this Fact Sheet.

*gTotal residual chlorine monitoring frequency is (How Often?) times a week. The chlorine disinfection is a backup system to the ultra violet system and therefore should not be needed
unless the ultra violet system has a failure and is by passed. The TRC limits are low enough to require analysis in the onsite lab which is open only 6 days a week. Frequency reduction
will remove a requirement that the lab be opened for a 7th day. In case of a bypass on any day the lab is closed, (Permittee) will bring in lab personnel to open the lab for TRC analysis

*jThe effluent shall not exceed the culinary source water intake by more than 400 mg/L of TDS *kThese reflect changes required with the adoption of UAC R317-1-3.3, Technology-based Phosphorus
Effluent Limits rule.
BIOSOLIDS
For clarification purposes, sewage sludge is considered solids, until treatment or testing shows that the solids are safe, and meet beneficial use standards. After the solids are tested
or treated, the solids are then known as biosolids. Class A biosolids, may be used for high public contact sites, such as home lawns and gardens, parks, or playing fields, etc. Class
B biosolids may be used for low public contact sites, such as farms, rangeland, or reclamation sites, etc.
SUBSTANTIAL BIOSOLIDS TREATMENT CHANGES
In 2012, <Permittee>decided to change the treatment of their biosolids from a lime stabilized product that met Class B standards, to a modern “state of the art” solar drying system that
basically consist of two screw presses for de-watering, and a greenhouse for further treatment and drying. The 2012 annual biosolids report states that 282 dry metric tons of biosolids
were stabilized with lime, to meet Class B standards, and land applied at a farm owned by Vic Warr, to cultivate grain for cattle feed, and 27 dry metric tons that met Class A standards,
that were sold or given away to the public. There are currently 328 dry metric tons of stored biosolids.
DESCRIPTION OF TREATMENT AND DISPOSAL
The Permittee submitted their 20XX annual biosolids report on Month Day, Year. The report states the Permittee produced XXXX dry metric tons (DMT) of solids. After the addition of wood
chips and green waste, a total of XXXX DMT of composted biosolids were produced and sold or given away to the public.
The solids are stabilized in activated sludge basins, with a solids retention time of 14-18 days in the basins. Solids wasted on a daily basis are sent to an aerobic digester with a
solids detention of five (5) to ten (10) days. After stabilization, the solids are dewatered by belt presses to about 15 percent solids. After dewatering the untreated solids are composted
to meet Class A standards and sold or given away.
Biosolids are processed using the Gore Covered Composting System, which is an In-Vessel Aerated Static Pile (IASP) windrow method to meet Class A biosolids requirements. The piles are
maintained at minimum operating temperatures of 55° C (131° F) for at least three (3) days. Piles typically exceed the three (3) day temperature requirements. After leaving the IASP
process, which is typically six (6) to eight (8) weeks, the composted solids are moved to curing piles for an additional eight (8) to twenty-four (24) weeks until no odor is present
and final screening occurs. All composted material is tested for Salmonella in accordance to 503 Regulations.
Biosolids were hauled to the Wasatch Regional Landfill, Inc. by District employees. No contract hauler(s) were used. Approximately 957 DMT were hauled off-site to the landfill for disposal.
See attached application and Letter of Authorization from Republic Services, operators of Wasatch Regional Landfill, Inc
The last inspection conducted at the land application site was Date. The inspection showed that <Permittee>was in compliance with all aspects of the biosolids management program.

SELF-MONITORING REQUIREMENTS
Under 40 CFR 503.16(a)(1), the self-monitoring requirements are based upon the amount of biosolids disposed per year and shall be monitored according to the chart below.

in the sanitary landfill (40 CFR 258.28(c)(1). No biosolids were landfilled in 20XX/Permittee disposed of XXX DMT of biosolids at the NAME Landfill.
BIOSOLIDS LIMITATIONS
Heavy MetalsClass A Biosolids for Home Lawn and Garden UseThe intent of the heavy metals regulations of Table 3, 40 CFR 503.13 is to ensure the heavy metals do not build up in the soil
in home lawn and gardens to the point where the heavy metals become phytotoxic to plants. The permittee will be required to produce an information sheet (see Part III. C. of the permit)
to made available to all people who are receiving and land applying Class A biosolids to their lawns and gardens. If the instructions of the information sheet are followed to any reasonable
degree, the Class A biosolids will be able to be land applied year after year, to the same lawns and garden plots without any deleterious effects to the environment. The information
sheet must be provided to the public, because the permittee is not required, nor able to track the quantity of Class A biosolids that are land applied to home lawns and gardens.Class
A Requirements With Regards to Heavy Metals If the biosolids are to be applied to a lawn or home garden, the biosolids shall not exceed the maximum heavy metals in Table 3 below. If
the biosolids do not meet these requirements, the biosolids cannot be sold or given away for applications to home lawns and gardens.Class B Requirements for Agriculture and Reclamation
Sites The intent of the heavy metals regulations of Tables 1, 2 and 3, of 40 CFR 503.13 is to ensure that heavy metals do not build up in the soil at farms, forest land, and land reclamation
sites to the point where the heavy metals become phytotoxic to plants. The permittee will be required to produce an information sheet (see Part III. C. of the permit) to be handed out
to all people who are receiving and land applying Class B biosolids to farms, ranches, and land reclamation sites (if biosolids are only applied to land owned by the permittee, the information
sheet requirements are waived). If the biosolids are land applied according to the regulations of 40 CFR 503.13, to any reasonable degree, the Class B biosolids will be able to be land
applied year after year, to the same farms, ranches, and land reclamation sites without any deleterious effects to the environment. Class B Requirements With Regards to Heavy Metals

If the biosolids are to be land applied to agricultural land, forest land, a public contact site or a reclamation site it must meet at all times:
The maximum heavy metals listed in 40 CFR Part 503.13(b) Table 1 and the heavy metals loading rates in40 CFR Part 503.13(b) Table 2; or
The maximum heavy metals in 40 CFR Part 503.13(b) Table 1 and the monthly heavy metals concentrations in 40 CFR Part 503.13(b) Table 3.

Class A Requirements for Home Lawn and Garden Use
If biosolids are land applied to home lawns and gardens, the biosolids need to be treated by a specific process to further reduce pathogens (PFRP), and meet a microbiological limit of
less than less than 3 most probable number (MPN) of Salmonella per 4 grams of total solids (or less than 1,000 most probable number (MPN/g) of fecal coliform per gram of total solids)
to be considered Class A biosolids. The <Permittee>has chosen to achieve PFRP through a method of <METHOD>. (or) At this time <Permittee>does not intend to distribute biosolids to the
public for use on the lawn and garden and thus is not required meet Class A Biosolids requirements currently.1. Windrow Method-Using the windrow method of composting, the temperature
needs to be maintained at 55 oC (131 oF) or higher for fifteen days, with a minimum of five turnings during those fifteen days, 2. Static Aerated Pile Method - composting using the static
aerated pile method, the temperature of the biosolids is maintained at 55°C (131°F) or higher for at least 3 days).
Both of these composting methods are found under (40 CFR 503.32(a)(8)(ii)).

The practice of sale or giveaway to the public is an acceptable use of biosolids of this quality as long as the biosolids continue to meet Class A standards with respect to pathogens.
If the biosolids do not meet Class A pathogen standards the biosolids cannot be sold or given away to the public, and the permittee will need find another method of beneficial use or
disposal.
Pathogens Class B
If biosolids are to be land applied for agriculture or land reclamation the solids need to be treated by a specific process to significantly reduce pathogens (PSRP). The <Permittee>has
chosen to achieve PSRP through <METHOD>: (or)At this time <Permittee>does not intend to distribute bulk biosolids for land application and thus is not required meet Class B Biosolids
requirements currently.
1. Under 40 CFR 503.32 (b)(2), TSSD may test the biosolids and must meet a microbiological limit of less than 2,000,000 MPN of fecal coliform per gram for the biosolids to be considered
Class B biosolids with respect to pathogens.
2.Under 40 CFR 503.32 (b)(3) The PSRP may be accomplished through anaerobic digesters that have a minimum retention time of 15 days at 95° F (35° C) or 60 days at 68° F (20°C).
3.Under 40 CFR 503.32 (b)(3) the PSRP may be accomplished through composting. To achieve this, the temperature must be above 40o C (104o F) or higher, and remain at 40o C or higher
for a minimum of five days. For four hours, during the five days, the temperature needs to exceed 55o C (113o F).
Vector Attraction Reduction (VAR)
If the biosolids are land applied <Permittee>will be required to meet VAR through the use of a method of listed under 40 CFR 503.33. The <Permittee>intends to meet the vector attraction
reduction requirements through one of the methods listed below. (or) At this time <Permittee>does not intend to distribute biosolids to the public for beneficial use, and will be disposing
of them in a landfill.Under 40 CFR 503.33(b)(11)
Under 40 CFR 503.33(b)(1), the solids need to be treated through anaerobic digestion for at least 15 days at a temperature of a least 35° C (95° F) with a 38% reduction of volatile solids.
Under 40 CFR 503.33(b)(5) the solids need treated through composting with a temperature of 40° C (104° F) or higher for at least 14 days with an average temperature of over 45° C (113°
F).
Under 40 CFR 503.33(b)(11) Sewage sludge placed on an active sewage sludge unit shall be covered with soil or other material at the end of each operating day.
If the biosolids do not meet a method of VAR, the biosolids cannot be land applied.
If the permittee intends to use another one of the listed alternatives in 40 CFR 503.33, the Director and the EPA must be informed at least thirty (30) days prior to its use. This change
may be made without additional public notice
Landfill Monitoring Under 40 CFR 258, the landfill monitoring requirements include a paint filter test to determine if the biosolids exhibit free liquid. If the biosolids do not pass
a paint filter test, the biosolids cannot be disposed in the sanitary landfill (40 CFR 258.28(c)(1).
Record Keeping
The record keeping requirements from 40 CFR 503.17 are included under Part III.G. of the permit. The amount of time the records must be maintained are dependent on the quality of the
biosolids in regards to the metals concentrations. If the biosolids continue to meet the metals limits of Table 3 of 40 CFR 503.13, and are sold or given away the records must be retained
for a minimum of five years. If the biosolids are disposed in a landfill the records must retained for a minimum of five years.
Reporting
<Permittee>must report annually as required in 40 CFR 503.18. This report is to include the results of all monitoring performed in accordance with Part III.B of the permit, information
on management practices, biosolids treatment, and certifications. This report is due no later than February 19 of each year. Each report is for the previous calendar year.

PATHOGEN MONITORING DATA (Anaerobic Cake)
The <Permittee>was not required to monitor the anaerobic biosolids (sludge cake) for pathogens. Therefore, there is not any monitoring data for the Class B biosolids. All biosolids land
applied in 20XX met the Class B pathogen standards through anaerobic digestion.
PATHOGEN MONITORING DATA (Aerobic Compost)
The TSSD was required to monitor the composted biosolids for pathogens at least six times in 2013 The TSSD had the choice to sample for fecal coliform or salmonella, and the TSSD chose
salmonella. Each monitoring episode needs to consist of seven samples, for a total 42 samples. All compost sold or given away in 2013 met the Class A pathogen standards for compost.
The monitoring data is below.

The State of Utah has adopted the 40 CFR 503 federal regulations for the disposal of sewage sludge (biosolids) by reference. However, since this facility is a lagoon, there is not any
regular sludge production. Therefore 40 CFR 503 does not apply at this time. In the future, if the sludge needs to be removed from the lagoons and is disposed in some way, the Division
of Water Quality must be contacted prior to the removal of the sludge to ensure that all applicable state and federal regulations are met
STORM WATER
Separate storm water permits may be required based on the types of activities occurring on site.
Permit coverage under the Multi Sector General Permit (MSGP) for Storm Water Discharges from Industrial Activities is required based on the Standard Industrial Classification (SIC) code
for the facility and the types of industrial activities occurring. If the facility is not already covered, it has 30 days from when this permit is issued to submit the appropriate Notice
of Intent (NOI) for the MSGP or exclusion documentation. Previously storm water discharge requirements and coverage were combined in this individual permit. These have been separated
to provide consistency among permittees, electronic reporting for storm water discharge monitoring reports, and increase flexibility to changing site conditions.
Permit coverage under the Construction General Storm Water Permit (CGP) is required for any construction at the facility which disturb an acre or more, or is part of a common plan of
development or sale that is an acre or greater. A Notice of Intent (NOI) is required to obtain a construction storm water permit prior to the period of construction.
Information onstorm water permit requirements can be found at http://stormwater.utah.gov
PRETREATMENT REQUIREMENTS
The permittee has not been designated for pretreatment program development because it does not meet conditions which necessitate a full program. The flow through the plant is less than
five (5) MGD, there are no categorical industries discharging to the treatment facility, industrial discharges comprise less than 1 percent of the flow through the treatment facility,
and there is no indication of pass through or interference with the operation of the treatment facility such as upsets or violations of the POTW's UPDES permit limits.
Although the permittee does not have to develop a State-approved pretreatment program, any wastewater discharges to the sanitary sewer are subject to Federal, State and local regulations.
Pursuant to Section 307 of the Clean Water Act, the permittee shall comply with all applicable Federal General Pretreatment Regulations promulgated, found in 40 CFR 403 and the State
Pretreatment Requirements found in UAC R317-8-8.
An industrial waste survey (IWS) is required of the permittee as stated in Part II of the permit. The IWS is to assess the needs of the permittee regarding pretreatment assistance.
The IWS is required to be submitted within sixty (60) days after the issuance of the permit. If an Industrial User begins to discharge or an existing Industrial User changes their
discharge the permittee must resubmit an IWS no later than sixty days following the introduction or change as stated in Part II of the permit.
It is required that the permittee submit for review any local limits that are developed to the Division of Water Quality for review. If local limits are developed it is required that
the permittee perform an annual evaluation of the need to revise or develop technically based local limits for pollutants of concern, to implement the general and specific prohibitions
40 CFR, Part 403.5(a) and Part 403.5(b). This evaluation may indicate that present local limits are sufficiently protective, need to be revised or should be developed.
BIOMONITORING REQUIREMENTS
A nationwide effort to control toxic discharges where effluent toxicity is an existing or potential concern is regulated in accordance with the Utah Pollutant Discharge Elimination System
Permit and Enforcement Guidance Document for Whole Effluent Toxicity Control (biomonitoring), dated February 2018. Authority to require effluent biomonitoring is provided in Permit
Conditions, UAC R317-8-4.2, Permit Provisions, UAC R317-8-5.3 and Water Quality Standards, UAC R317-2-5 and R317 -2-7.2.Since the permittee is a major municipal discharger, the permit
will require whole effluent toxicity (WET)testing. Chronic toxicity testing will be conducted using both species, alternating Ceriodaphnia dubiaquarterly and Pimephales promelas (fathead
minnow) quarterly. The permit will contain the standardrequirements for accelerated testing upon failure of a WET test and a PTI (Preliminary ToxicityInvestigation) and TRE (Toxicity
Reduction Evaluation) as necessary. The IC25 will be based upon seasons: Summer (Jul-Sep) 52%, Fall (Oct-Dec) 33%, Winter (Jan-Mar) 22%, Spring (Apr-Jun) 32% totaleffluent. The permit
will contain the standard requirements for accelerated testing upon failure of a WETtest and a PTI (Preliminary Toxicity Investigation) and TRE (Toxicity Reduction Evaluation) asnecessary.

Industrial Waste Survey
This Page Intentionally Left BlankIndustrial Pretreatment Wastewater SurveyDo you periodically experience any of the following treatment works problems:foam, floaties or unusual colorsplugged
collection lines caused by grease, sand, flour, etc.discharging excessive suspended solids, even in the wintersmells unusually badwaste treatment facility doesn’t seem to be treating
the waste rightPerhaps the solution to a problem like one of these may lie in investigating the types and amounts of wastewater entering the sewer system from industrial users.An industrial

user (IU) is defined as a non-domestic user discharging to the waste treatment facility which meets any of the following criteria: 1.has a lot of process wastewater (5% of the flow
at the waste treatment facility or more than 25,000 gallons per work day.)Examples:Food processor, dairy, slaughterhouse, industrial laundry.2.is subject to Federal Categorical Pretreatment
Standards;Examples:metal plating, cleaning or coating of metals, blueing of metals, aluminum extruding, circuit board manufacturing, tanning animal skins, pesticide formulating or packaging,
and pharmaceutical manufacturing or packaging,3.is a concern to the POTW.Examples:septage hauler, restaurant and food service, car wash, hospital, photo lab, carpet cleaner, commercial
laundry.All users of the water treatment facility are prohibited from making the following types of discharges:1.A discharge which creates a fire or explosion hazard in the collection
system.2.A discharge which creates toxic gases, vapor or fumes in the collection system.3.A discharge of solids or thick liquids which creates flow obstructions in the collection system.4.An
acidic discharge (low pH) which causes corrosive damage to the collection system.5.Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will
cause problems in the collection system or at the waste treatment facility.6.Waste haulers are prohibited from discharging without permission. (No midnight dumping!)When the solution
to a sewer system problem may be found by investigating the types and amounts of wastewater entering the sewer system discharged from IUs, it’s appropriate to conduct an Industrial Waste
Survey.An Industrial Waste Survey consists of:Step 1: Identify Industrial UsersMake a list of all the commercial and industrial sewer connections.Sources for the list:business license,
building permits, water and wastewater billing, Chamber of Commerce, newspaper, telephone book, yellow pages.Split the list into two groups:domestic wastewater only--no further information

REASONABLE POTENTIAL ANALYSIS
Water Quality has worked to improve our reasonable potential analysis (RP) for the inclusion of limits for parameters in the permit by using an EPA provided model. As a result of the
model, more parameters may be included in the renewal permit. A Copy of the Reasonable Potential Analysis Guidance (RP Guide) is available at water Quality. There are four outcomes
for the RP Analysis. They are;
Outcome A:A new effluent limitation will be placed in the permit.
Outcome B:No new effluent limitation. Routine monitoring requirements will be placed or increased from what they are in the permit,
Outcome C:No new effluent limitation. Routine monitoring requirements maintained as they are in the permit,
Outcome D:No limitation or routine monitoring requirements are in the permit.Initial screening for metals values that were submitted through the discharge monitoring reports showed that
a closer look at some of the metals was not needed.
A Summary of the RP Model inputs and outputs are included in the table below.
The Metals Initial Screening Table and RP Outputs Table are included in this attachment.RP input/output summary
