1. Introduction
1.1 Background
Every summer, a large hypoxic zone forms in the Gulf of Mexico. This zone, in which the amount of
dissolved oxygen is too low for many aquatic species to survive, is fueled primarily by excess nutrients,
mainly nitrogen and phosphorus, from the Mississippi/Atchafalaya River Basin (MARB). The hypoxic
zone is also affected by temperature and by salinity stratification, or layering, of Gulf waters that
prevents mixing.
The Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (Hypoxia Task Force or HTF) is a
federal, state, and tribal partnership established in 1997 to gain a better understanding of the causes
and effects of the northern Gulf of Mexico hypoxic zone and to reduce its size, severity, and duration.
HTF members are representatives from five federal agencies (the United States Environmental
Protection Agency or U.S. EPA, United States Department of Agriculture, United States Department of
Commerce, United States Department of the Interior, and United States Army Corps of Engineers); 12
states (Arkansas, Illinois, Indiana, Iowa, Kentucky, Louisiana, Minnesota, Mississippi, Missouri, Ohio,
Tennessee, and Wisconsin); and a representative from the National Tribal Water Council.
In 2001, the HTF set a goal, subject to the availability of additional resources, to reduce or make
significant progress toward reducing the five-year average areal extent of the Gulf of Mexico hypoxic
zone to less than 5,000 square kilometers (km2) by 2015. In 2007, the U.S. EPA Science Advisory Board's
Hypoxia Advisory Panel estimated that a 45-percent reduction in total nitrogen (TN) and total
phosphorus (TP) loads to the Gulf of Mexico would be needed for the HTF to reach its goal.
In 2008, the HTF released an Action Plan in which HTF states committed to developing state strategies
for reducing nutrient loads to the Gulf of Mexico and water bodies within the MARB, with strong federal
support. These strategies are each state's road map for prioritizing and targeting watersheds that
contribute significant amounts of nitrogen and phosphorus to the Gulf and are a vehicle by which to
coordinate with partners and stakeholders. The state strategies are complemented by a federal strategy
outlining financial, scientific, and technical assistance for achieving the HTF's goal.
In 2015, the HTF committed to retaining its 2001 goal of reducing the areal extent of the hypoxic zone in
the Gulf of Mexico to less than 5,000 km2. Recognizing the enormity of the task of reducing nutrient
loads on a subcontinental scale, however, the HTF extended the time for reaching that goal from 2015
to 2035. The HTF adopted an interim target of 20-percent reduction in TN and TP loads by the year 2025
as a milestone toward achieving the final hypoxic zone goal by 2035. As part of its revised Goal
Framework, the HTF also committed to regularly tracking progress towards its 2025 interim target and
2035 goal.
1.2 Tracking Point Source Reduction Progress
For point sources, the HTF initially agreed to use two common measures to track progress toward the
interim load reduction target: (1) the number of major sewage treatment plants, including publicly
owned treatment works (POTWs), issued National Pollutant Discharge Elimination System (NPDES)
permits with monitoring requirements for nitrogen and/or phosphorus; and (2) the number of major
sewage treatment plants issued NPDES permits with numeric discharge limits for nitrogen and/or
1
-------
phosphorus. The HTF chose those measures because data and methodology limitations at the time
precluded swift adoption of a common approach for directly measuring load reduction.
In February 2016, the HTF released its first Report on Point Source Progress in Hypoxia Task Force
States. That report used data as of September 30, 2014, to document that:
57 percent of major sewage treatment plants in HTF states monitored levels of both nitrogen
and phosphorus;
74 percent of the plants monitored the level of at least one of those nutrients;
33 percent of the plants had a discharge limit for either nitrogen or phosphorus; and
5 percent of the plants had limits for both nutrients.
This second report on point source progress uses data as of September 30, 2017, to document further
progress made by HTF states in adopting nutrient monitoring and discharge limits. This report also
includes an additional common measure of point source progress that the HTF adopted in 2018, after
developing a common reporting methodology: loads of nitrogen and phosphorus discharged by major
sewage treatment plants. This new measure is based on 2017 calendar year data.
The HTF continues to examine options for deriving a point source-specific baseline for the 1980-1996
period that the HTF uses to generally measure progress in reducing basinwide nutrient loads. At a
minimum, future progress reports will be able to show changes from the 2017 loads documented in this
report.
Some of the HTF states use state-specific approaches to making and tracking progress toward reducing
point source loads. Many of the states have made additional progress in establishing monitoring and
permit limits since the data in this report were compiled shortly after September 30, 2017. In Appendix
B, most of the states describe work they are doing to reduce point source nutrient loads beyond the
common measures in this report and/or include more recent data on nutrient monitoring and permit
limits.
In addition to reporting on point source progress, the HTF tracks progress on reducing loads from
nonpoint sources. In May 2018, the HTF issued its first report on nonpoint source measures, which is
available at https://www.epa.gov/ms-htf/report-nonpoint-source-progress-hypoxia-task-force-states.

2. Data Sources and Methodology
2.1 Nutrient Monitoring and Permit Limits
To document state progress on establishing nitrogen and phosphorus monitoring requirements and
discharge limits at major sewage treatment plants, the HTF uses a common data system, U.S. EPA's
Integrated Compliance Information System (ICIS). ICIS retains NPDES permit data that facilities submit to
states and U.S. EPA in their monthly Discharge Monitoring Reports (DMRs) (see U.S. EPA's Enforcement
and Compliance History Online at https://echo.epa.gov/, the public interface with ICIS). ICIS also
contains limit and monitoring requirement records associated with NPDES permits. For more
information about states sharing data with U.S. EPA, see the NPDES eReporting web page at
https://www.epa.gov/compliance/npdes-ereporting.
For this report, U.S. EPA downloaded nutrient monitoring and limits data from ICIS through September
30, 2017, which is the end of the federal fiscal year and U.S. EPA's deadline for states to complete data
entry to ICIS for that federal fiscal year. Those data provide a common baseline for this report.
To obtain the number of NPDES permits with monitoring requirements and discharge limits for nitrogen
or phosphorus, U.S. EPA first downloaded the complete list of facilities for each HTF state labeled with
Standard Industrial Classification (SIC) Code 4952, Sewerage Systems, as well as facilities with no SIC
Code but labeled as POTWs in the Facility Type Indicator field. U.S. EPA then filtered out any "nonmajor"
facilities. Generally, a "major" POTW has a design flow of 1.0 million gallons per day (MGD) or more. In
aggregate, those facilities typically discharge a very large proportion of the municipal wastewater
volume discharged in a state. This effort provided the universe of major municipal sewage treatment
and resource recovery facilities in each state.
For this report, U.S. EPA applied an additional geographic filter within state boundaries to include only
major sewage treatment plants that discharge to the MARB.1 Some permitted facilities in Indiana, Ohio,
Minnesota, and Wisconsin discharge to the Great Lakes or Hudson Bay watersheds and were thus
excluded from the analysis; as were facilities in Louisiana and Mississippi that discharge to the Gulf of
Mexico via the Pearl River and other non-MARB rivers.
From the universe of major sewage treatment plants discharging to the MARB, U.S. EPA tallied the
number of facilities with discharge monitoring and limits for various forms of nitrogen (excluding
ammonia) and phosphorus.2 Appendix C documents the parameters included in counts of nutrient
monitoring and limit requirements. This process mirrors the approach U.S. EPA and the Association of
Clean Water Administrators apply to each state nationwide to document major POTWs with nutrient
monitoring and limit requirements.
1 The geographic boundary of MARB was downloaded from the United States Geological Survey at
https://water.usgs.gov/GIS/dsdl/ds641 nasqan wbdl2.zip.
2 Permit authorities generally limit ammonia because of its near-field toxic effect. Ammonia treatment often
involves a process that yields other forms of nitrogen, which are then discharged.

2.2 Nutrient Loading
The U.S. EPA ICIS data system also contains data on facility wastewater discharge flows and monitored
pollutant concentrations. U.S. EPA has developed a Water Pollutant Loading Tool (Loading Tool) that
uses those flow and concentration data to calculate facilities' pollutant discharge loads or, for facilities
that do not monitor nitrogen or phosphorus, estimates loads using typical pollutant concentrations and
facility discharge flows.3 In 2012, EPA submitted its draft methodology for estimating nutrient discharges
for independent peer review by the USGS. Since then the HTF Point Source Workgroup (Workgroup)
worked with the USGS to refine the Loading Tool methodology for using monitoring data to calculate
nutrient discharges, and for estimating nutrient loads when monitoring data are not available. The HTF
has search pages and methodology in the Loading Tool available at
https://echo.epa.gov/trends/loading-tool/evervdav-searches. For more information about the
methodology the HTF uses, see the Hypoxia Task Force Search Help page at
https://echo.epa.gov/help/loading-tool/hypoxia-task-force-search-help.
In addition to loads from major sewage treatment plants, the Workgroup explored the possibility of
including loads from other sources. Tracking loads from facilities in industries that use large volumes of
cooling water, such as steam electric power generating stations or petroleum refineries, is confounded
by a lack of data on influent nutrient loads, making it difficult to distinguish loads that are added from
loads that are simply passed through those plants. Once the Workgroup excluded industries using high
volumes of cooling water, its analyses showed the remaining industries discharge, in aggregate, much
lower loads than major sewage treatment plants. Similarly, minor (smaller) sewage treatment plants
contribute insignificant loads compared to major sewage treatment plants. Therefore, to streamline
data analysis and verification, this report focuses on nutrient loads from major sewage treatment plants.
2.3 Data Verification and Reconciliation
U.S. EPA worked with the 12 HTF states to compare their NPDES program data to the data in ICIS. In
general, state data on monitoring and limits matched the data in ICIS and any discrepancies identified
were reconciled.
For this report, the Loading Tool's standard procedure for calculating or estimating facility loads could
not be used for some facilities because of limitations (e.g., the Loading Tool accesses discharge data in
ICIS only from certain facility outfalls). For those facilities, loads were calculated using appropriate data
or estimated values as individually detailed in Appendix A at the end of each state's data as "Notes for
values marked with +".

3. Status of HTF States in Reducing Point Source Loads
3.1 Summary Status Report
Tables 1, 2, and 3 provide a snapshot of point source nitrogen and phosphorus monitoring requirements
and discharge limits as of September 30, 2017 and loads as of December 31, 2017. Table 1 presents the
total number and percentage of major sewage treatment plants discharging to the MARB that monitor
discharge for nitrogen and/or phosphorus. Table 2 presents the number and percentage of major
sewage treatment plants discharging to the MARB with nitrogen and/or phosphorus discharge limits.
Table 3 presents the total annual loads of nitrogen and phosphorus from major sewage treatment
plants. Appendix A contains the complete facility-by-facility NPDES permit data used to prepare these
summary tables. Some notable findings include the following:
Across all 12 HTF states, 70 percent of permits for major sewage treatment plants discharging to
the MARB included monitoring requirements for both nitrogen and phosphorus, an increase
from 56 percent in 2014. Eighty-six percent of the permits for major sewage treatment plants
included monitoring requirements for at least one nitrogen or phosphorus parameter, an
increase from 71 percent in 2014 (see Figure 1).
Thirty-two percent of the permits for major sewage treatment plants in HTF states that
discharge to the MARB have limits for nitrogen or phosphorus, an increase from 27 percent in
2014; most of those permits have phosphorus limits. Four percent of the permits for major
sewage treatment plants include limits for both nitrogen and phosphorus (see Figure 2).
Based on the methodology and data described in Section 2.2, the 1,199 major sewage treatment
plants in HTF states that discharge to the MARB contributed 287,708,571 pounds of nitrogen
and 44,972,256 pounds of phosphorus to nutrient loads in the MARB. For context, the United
States Geological Survey (USGS) calculates that total MARB nutrient loads to the Gulf in Water
Year 2017 were approximately 3,320,000,000 pounds of nitrogen and 314,000,000 pounds of
phosphorus (see Figure 3).4

documents how EPA used the Water Pollutant Loading Tool methodology and data in ICIS or state-sourced data to
calculate or estimate loads from each facility.

3.2 State-Specific Supplemental Information
The HTF recognizes that the three common measures used in this report might not fully reflect all the
work that states have done to reduce point source nutrient discharges. Also, while this report reflects a
snapshot of progress as of September 30, 2017, states have made additional progress on establishing
monitoring requirements and limits for point sources since then. Appendix B includes supplemental
information provided by many of the HTF states to further document their work to reduce point source
nutrient loads.
9
-------
4. Next Steps
4.1 Develop a Point Source Baseline
The HTF continues to explore the feasibility of estimating baseline point-source nutrient loads for the
HTF states using a 1992 dataset compiled by USGS.6 Those 1992 USGS data appear to be the best
common data across the 12 HTF states that fall within the 1980-1996 averaging period serving as the
overall baseline for HTF load tracking.
4.2 Continue Making Progress on Monitoring and Permit Limits for Nitrogen and
Phosphorus
HTF states continue to work to increase the number of major sewage treatment plants with discharge
monitoring requirements for nitrogen and phosphorus. Increased discharge monitoring will help to
calculate accurate load reductions and identify facilities for which additional permit limits for nitrogen
and/or phosphorus are appropriate. Some states now include, and other states are exploring, influent
monitoring in their NPDES permits to better track load reduction within treatment plants and identify
opportunities to optimize treatment.
4.3 Continue Reporting on Point Source Progress
The HTF intends to continue to release periodic reports on progress made in reducing point-source
contributions to nutrient loads. Those reports will document progress on the number of major sewage
treatment plants with monitoring requirements and, as appropriate, permit limits for nitrogen and/or
phosphorus; nutrient loads discharged from major sewage treatment plants and, potentially, other
sources; and other state work to reduce point source nutrient loads.

-------
Appendix A State-Specific, Facility-Level ICIS Spreadsheets
Some loading values are estimated because of incomplete flow or concentration data reported to ICIS.
Values in unmarked cells are based on actual flow and concentration measurements and calculated by the Water Pollutant Loading Tool
(Loading Tool).
Values marked with an asterisk (*) are estimated by the Loading Tool based on typical pollutant concentrations (TPCs) for total nitrogen
(TN) and total phosphorus (TP).
Values marked with a dagger (+) were calculated independently. The data and methods used to calculate most of those values are
specified at the end of each state's data in tables titled "Notes for values marked with +."7
Each table lists the sewage treatment plants in numerical order by National Pollutant Discharge Elimination System (NPDES) permit number
(NPDES ID).
The data in the following tables reflect the status of nutrient monitoring, limits, and loads in each of the MARB drainage areas of the 12 HTF
states at a common point in time: September 30, 2017, for monitoring and limits and December 31, 2017, for loads. While these data reflect a
common snapshot of state progress, states have made additional progress since late 2017. Some states have included information on more
recent progress in their state supplements (Appendix B).

Monthly averages of flow ("Flow, in conduit or thru treatment plant (50050)") downloaded from
https://echo.epa.gOv/effluent-charts#IL0030813. TN and TP were monitored at this facilitv, but the monitoring
data were coded to an internal outfall that could not be captured by the default DMR Loading Tool per protocol.
Only daily maxima for TN, TP were reported in ICIS monthly, so they were downloaded from the same website to
estimate actual concentrations in calculation annual loads. Calculated loads based on TPCs would otherwise
provide similar estimates.

Monthly averages of flow ("Flow, in conduit or thru treatment plant (50050)") and TP concentration
("Phosphorus, total fas PI (00665)") were downloaded from https://echo.epa.gOv/effluent-charts#IL0055981 to
calculate annual TP load in 2017. For TN ("Nitrogen, total [as N] (00600)"), only daily maximum concentrations
were reported, and not monthly averages. For each month, the daily maximum value is lower than the 12.75
mg/LTPC, which would otherwise be used by the Loading Tool. Therefore, daily maxima were used to estimate
load.

Much of the following data are not based on U.S. EPA ICIS, but rather queried from the database of Iowa Department of Natural Resources
(DNR). A previous compatibility issue between the two systems prevented accurate flow of information from Iowa DNR to U.S. EPA. Nutrient
loads from facilities marked with double asterisks (**) were calculated by Iowa DNR using publicly available data from DMRs or Iowa DNR
records following the methods used by U.S. EPA's Loading Tool. Data for those facilities can be found at
https://www.iowadnr.gov/Environmental-Protection/Water-Qualitv/Nutrient-Reduction-Strategy.

Data from many facilities in Missouri, as marked with + in Table A-15, were absent from the Loading Tool. Missouri DNR provided data for those
facilities and U.S. EPA calculated the loadings following the same methodology as the Loading Tool; the data can be accessed at
https://dnr.mo.gov/mocwis public/dmrDisclaimer.do. Table A-16 provides additional information about errors in the data for two of the
facilities marked with +.

Wisconsin Department of Natural Resources calculated TN and TP loads following the methods used in U.S.
EPA's Loading Tool. The annual average flow of 42.22 MGD was used together with TPCs for TN and TP to
calculated TN and TP loads.
RICE LAKE CITY WWTF
WI0021865
Monthly averages of flow ("Flow, in conduit or thru treatment plant (50050)") and TP concentration
("Phosphorus, total fas PI (00665)") were downloaded from https://echo.epa.gov/effluent-
charts#WI0021865 to calculate annual loading in 2017. For TN, the 1-month load in the Loading Tool (11,724
lb for May 2017) was extrapolated for the whole year (11,724 lb x 12 = 140,690 lb).
RIVER FALLS CITY WWTF

gives 2017 N loading as 10,849 Ib/yr. It seems, however, to account only for inorganic nitrogen. DIN, TKN,
and NO2 + NO3 were reported for this facility. Although the Loading Tool based TN load on inorganic nitrogen
data, TKN + NO2 + NO3 is a better measure. Using monthly averages of effluent flow ("Flow, in conduit or
thru treatment plant (50050)") from https://echo.epa.gOv/effluent-charts#WI0031496, TN load should be
10.6 mg/L (NO2+NO3) + 1.3 mg/L (TKN) = 11.9 mg/L in November 2017. November 2017 load = 3,044.75, then
extrapolated 2017 load = 36,537 Ib/TN.
Notes: DIN = dissolved inorganic nitrogen; lb = pounds; Ib/yr = pounds per year; mg/L = milligrams per liter; N02 = nitrogen dioxide; N03 = nitrate; TKN = total Kjeldahl nitrogen.

Appendix B State-Specific Supplemental Information
This appendix presents additional material prepared by many of the HTF states on their efforts to reduce
point source nutrient loads, beyond the common measures in this report, which use data on monitoring
requirements and permit limits for major sewage treatment plants from the end of federal fiscal year
2017 (September 30, 2017), and from the end of calendar year 2017 for estimated discharge loads.
B.l Illinois Supplemental Information
The Illinois Environmental Protection Agency (IEPA) has not adopted numeric TN or TP water quality
standards (WQS) for streams. It has, however, convened a Nutrient Science Advisory Committee to
develop recommendations for numeric nitrogen and phosphorus WQS. The Committee released their
report (Recommendations for Numeric Nutrient Criteria and Eutrophication Standards for Illinois Streams
and Rivers) in December 2018. The report was provided for public notice prior to IEPA proposing any
nutrient WQS to the Illinois Pollution Control Board, a quasi-legislative body responsible for adopting
WQS in Illinois. At the time of this writing, IEPA is reviewing the public comments.
IEPA has not issued any National Pollutant Discharge Elimination System (NPDES) permits with TN
permit limits. It has, however, issued 17 NPDES permits that each contains a goal for TN removal.
All new and expanding major municipal facilities will have a phosphorus limit of 1.0 milligram per liter
(mg/L) as required by the effluent standard specified in Title 35 Illinois Administrative Code § 304.123(g)
and might receive more stringent nutrient limits through the antidegradation process.
Since 2017, under Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) permits, the
Calumet (354 million gallons per day [MGD]), Stickney (1,200 MGD), and O'Brien (333 MGD) plants have
been subject to the following requirements:9
Meeting an annual phosphorus limit of 0.5 mg/L by 2030.
Setting up a Nutrient Oversight Committee to prepare a nutrient implementation plan.
Developing a feasibility report to meet 0.5 mg/L, 0.3 mg/L, and 0.1 mg/L for phosphorus.
Since 2018, all major sewage treatment plants (more than 1.0 MGD) have been subject to the following
requirements:
Meeting an annual phosphorus limit of 0.5 mg/L by 2030 if the treatment method is biological
phosphorus removal.
o Meeting an annual phosphorus limit of 0.5 mg/L by 2025 if the treatment method is a
chemical phosphorus removal option,
o Meeting an annual phosphorus limit of 0.5 mg/L by 2035 if the treatment method is a
biological nutrient removal option.
Exceptions to these requirements include if the construction of the facilities would cause
widespread social and economic hardship for the community.
A Nutrient Assessment Reduction Plan (NARP) might be required in some cases:
9 Based on the January 25, 2017, Settlement Agreement between MWRDGC and environmental groups.
B-l
-------
o A NARP and a permit limit will be required for all major municipal facilities upstream of a
segment impaired for aquatic algae, aquatic plants (macrophytes), or dissolved oxygen
(DO) that has the signature of excess algae (above 100-percent DO saturation and below
the DO WQS within a 24-hour period),
o A NARP will be required for all major municipal facilities that indicate there is a risk of
eutrophication downstream of the discharge. A "risk of eutrophication" will include one of
the following situations for monitoring downstream of the discharge:
¦ Exceeding the upper standard for pH (pH higher than 9.0),
¦ Median sestonic chlorophyll a higher than 26 micrograms per liter, or
¦ pH higher than 8.35 and daily maximum DO saturation more than 110 percent on 2
or more days.
All major municipal facilities will be required to develop a feasibility report to meet 0.5 mg/L, 0.3
mg/L, and 0.1 mg/L for phosphorus.
All major municipal facilities will be required to optimize their existing facilities for nutrient
removal.
B.2 Indiana Supplemental Information
The Indiana Department of Environmental Management (IDEM) has a nonrule policy document (NPD)
that establishes the Commissioner's determination that an effluent containing no more than 1.0 mg/L of
TP as a monthly average is needed for sanitary WWTPs with average design flows 1 MGD or more. The
NPD can be found here: https://www.in.gov/idem/files/nrpd water-019.pdf.
Additionally, IDEM began requiring major (1.0 MGD or more average design flow) sanitary WWTPs to
conduct monthly monitoring of TN in the effluent. This monitoring requirement is included in impacted
permits with any application for permit renewal or permit modification application received by IDEM
after January 1, 2019.
IDEM is actively updating NPDES permits and implementing the TP NPD. The IDEM Office of Water
Quality updated Indiana's table in Appendix A (Table A-5) to include effluent limits for TP instituted in
recently issued permits and current permit expiration dates of NPDES permits that have not yet been
renewed to indicate when TP limits will be implemented in the NPDES permits (upon next permit
renewal). Table B-l shows the recent updates marked with a double dagger (t).

B.3 Iowa Supplemental Information
Progress in reducing nutrient discharges in Iowa is being evaluated by means other than a simple count
of the number of permits that specify nutrient limits and/or monitoring requirements. Such metrics
include the number of permits issued that require feasibility studies, of studies submitted, of
construction schedules included in permits, and of facilities that have completed construction and are
operating nutrient reduction technologies.
Nutrient Reduction Strategy Progress
One of the goals of the Nutrient Reduction Strategy (NRS) was to annually issue or reissue NPDES
permits to at least 20 (or 15 percent) of the facilities listed in the strategy. Those facilities include all
major POTWs (more than 1 MGD), all major industries, and minor industries that use a biological
treatment process.
Table B-2 shows that a total of 125 permits requiring feasibility studies had been issued as of May 31,
2018. The goal of 20 permits per year has been met or exceeded in each of the 5 years the NRS has been
in place. The total number of facilities addressed by the NRS and, therefore, the number of permits that
will require completion of a feasibility study changes slightly from year to year for several reasons:
B-5
-------
New industries begin operating.
Industries previously discharging to POTWs begin operating separately from the city.
An industry might cease operations altogether or dispose of its wastewater by means other than
discharging to a river or stream.
City wastewater treatment facilities (WWTFs) are replaced with new facilities or are expanded
to treat larger volumes.
Eighty-two feasibility studies had been submitted as of May 31, 2018. Twenty-seven of the studies have
resulted in permit amendments to include schedules for construction and optimization of nutrient
treatment technology. Eight permits had been amended under the NRS to include limits as of May 31,
2018.

A total of 178 permits have been issued to facilities in Iowa that are not affected by the NRS that specify
limits for one or more nitrogen compounds (excluding ammonia nitrogen) and one permit that has been
issued to a facility not affected by the NRS that specifies limits for one or more phosphorus compounds.
Limits in these permits are either required by federal effluent standards or are based on a total
maximum daily load (TMDL) developed by the Iowa Department of Natural Resources (DNR). In many
cases these limits do not require a reduction in the amount of nitrogen or phosphorus discharged, but
neither do they allow an increase in the amount discharged.
Several POTWs and industries have constructed or are presently constructing biological or chemical
nutrient reduction facilities. Many others are planning to construct facilities in the coming years.
Improved metrics are being evaluated to document whether a treatment plant was upgraded to remove
nutrients or optimized to meet the NRS goals, and what facilities are currently under construction.

Analysis of Data
Results of weekly monitoring are now available for 93 facilities whose permits have been reissued since
the strategy was released. Data in Table B-3 reflect the actual results from 72 POTWs for which at least
10 months of weekly sample results were available for both raw waste and final effluent and the 21
industries with at least 10 months of data for raw waste, final effluent or both for the period May 1,
2017, through April 30, 2018. Not all industries operate WWTPs and, therefore, not all have raw waste
data.

By subtracting the average pounds per day (lb/day) in the effluent discharged by each POTW from the
average lb/day in the raw waste, then multiplying the resulting value by 365, reasonable approximations
of the total pounds of TN and TP removed by each of the 72 POTWs during 2017-18 were calculated.
Adding the calculated values for all these individual facilities shows that POTWs removed approximately
7,998 tons of TN and 1,452 tons of TP in a 12-month period. Industries removed approximately 856 tons
of TN and 337 tons of TP in a 12-month period.
Most of the facilities have not constructed treatment specifically designed to reduce TN and TP but
nonetheless some achieved significant reductions in one or both nutrients. Greater reductions are
anticipated for most facilities following installation or implementation of specific nutrient reduction
practices and technologies.
Iowa Point Source Baseline Pilot Project
In 2016, Iowa DNR began coordinating with USGS to better understand historical nutrient loads from
point sources in the state. USGS shared a draft data set that contained annual TN and TP load estimates
for Iowa point sources for the years 1992, 1997, and 2002. Iowa DNR evaluated the 1992 annual
nutrient loads and concluded the shared data set could be used, with modification, to estimate baseline
nutrient loads for Iowa point sources.
B-7
-------
Annual TN and TP loads in 1992 were estimated for Iowa's major POTWs, minor domestic wastewater
dischargers (including POTWs and semipublic facilities), and industrial dischargers that provide biological
treatment of process wastewater (BTP). Those loads were then summed to provide the point source
baseline TN and TP load estimates shown in Table B-4. The full report titled Nitrogen and Phosphorus
Load Estimates from Iowa Point Sources during the 1980-96 Hypoxia Task Force Baseline Period can be
found at http://www.nutrientstrategy.iastate.edu/documents.

As a result of discussions with stakeholders regarding the baseline estimates, Iowa DNR has begun
integrating the baseline estimates into NRS progress tracking efforts. Stakeholders asked for a
comparison of current point source loads to the 1980-96 baseline, to the loads at the time the NRS was
developed, and to the estimated loads if all facilities covered by the NRS were to meet the NRS goals.
Preparing this load comparison required three steps. First, the original point source loads estimated at
the time of NRS development were recalibrated using the newer, more accurate methodology employed
to estimate the 1980-96 baseline. This entailed using 2013 monthly average effluent flow data and
either Iowa-specific typical pollutant concentrations for TN and TP (for major POTWs and minor
domestic wastewater dischargers) or long-term average effluent concentrations (for industrial
dischargers with BTP). Second, loads for the 2018 reporting period were calculated using actual facility-
specific TN and TP load data when available and modeled estimates using the new methodology. Third,
TN and TP effluent concentrations of 10 mg/L and 1 mg/L, respectively, were used to estimate loads if all
facilities covered by the NRS were to meet the NRS goals (assumed flows equal to 2013 levels). Figure
B-l summarizes the outcome of that effort by providing point source load values for the 1980-96
baseline, the 2013 recalibrated loads, and 2018 reporting period loads. The dashed lines in Figure B-l
provide the estimated loads in the case that all NRS-covered facilities met the NRS goals.

B.4 Kentucky Supplemental Information
The Kentucky Division of Water (Division) continues to work to reduce nutrient discharges from
permitted facilities. It has added nutrient monitoring requirements for influent and effluent in the
discharge permit for all publicly owned treatment works (POTWs), It also is working toward adding
technology-based limits to industrial and POTW discharges that contribute significant nutrient loads to
receiving waters.
The division is conducting the legal, regulatory, technical, and resource analyses necessary to adopt a
treatment-optimization, technology-based permitting approach similar to the approach used by the
state of Iowa. It has convened a voluntary Wastewater Advisory Council, at the discretion of the Division
Director, which consists of diverse wastewater stakeholders, to discuss, plan, and recommend
approaches to addressing existing and emerging wastewater issues. The Council has formed
subcommittees to develop recommendations on nutrients and permitting, operator certification,
operational permits, asset management, and other issues. The Council has recommended that the
Division adopt a technology-based permitting approach with an optimization study requirement to drive
permit goals of 75-percent mass reduction in total phosphorus (TP) and 66-percent mass reduction in
total nitrogen (TN) in effluent.
Kentucky House Bill (HB) 513 (2018 legislative session) amended Kentucky Revised Statutes 224.73-130
to 224.73-150 to authorize the Kentucky Energy and Environment Cabinet (Cabinet) to develop
regulations that require privately owned wastewater treatment plants (WWTPs) to obtain insurance or a
B-9
-------
letter of credit, maintain adequate revenue to ensure continuity of service, and implement an asset
management plan. The statute also contains conditions for the appointment of a receiver if a privately
owned WWTP presents a threat to public health or the environment, is in abject noncompliance, or has
an owner who is unable or unwilling to provide for the proper operation of the facility.
Using quarterly ambient monitoring data statewide at the confluence of 8-digit hydrologic unit code
(HUC 8) watersheds, the Division has conducted a nutrient load and yield study, including rolling 5-year
average trends for the timeframe of 2005-2017. The Division anticipates using this data set to inform
updates to the Nutrient Reduction Strategy prioritization process as well as to identify permitting
priorities.
The Division is participating in a water quality trading (WQT) project for the Ohio River Basin, which is
being implemented by the Electric Power Research Institute. The Ohio River Basin Interstate Water
Quality Trading Project (the Project) was signed in 2012. The Cabinet is currently responsible for credit
verification and credit certification within the credit registry process, for any credits generated in
Kentucky. Amendments to the Project added three key elements: (1) allowing the use of new, more
rigorous water quality models better able to estimate edge-of-field nutrient reductions for credit
calculations; (2) in an attempt to relieve state agencies of undue burden in completing on-the-ground
verifications for pre- and post-installation of best management practices (BMPs), the Project would
revise its practices for verification to schedule a random selection on random farms to verify BMP
installation and effectiveness, and include remote sensing technologies to verify BMPs, where possible;
and (3) the Project proposes to contract directly with other agencies and landowners in the area to get
on-the-ground projects implemented.
The Division, in partnership with the Kentucky Division of Compliance Assistance, continues to
implement the Wastewater Treatment Plant Optimization Program to assist POTW facilities in reducing
their costs and improving environmental performance through optimizing their energy efficiency. When
implemented, these optimization efforts have demonstrated significant reductions in the nutrient
profile of wastewater effluent.
B.5 Louisiana Supplemental Information
The Louisiana Nutrient Management Strategy: Protection, Improvement, and Restoration of Water
Quality in Louisiana's Water Bodies (Louisiana Nutrient Management Strategy Interagency Team, 2014)
provides a collaborative approach to addressing progress towards nutrient management within the
state. One of the strategic actions listed in Section E.3.9 of the strategy is monitoring nutrients from
point sources. Point source discharges into Louisiana waters are managed through the Louisiana
Pollutant Discharge Elimination System (LPDES) Permit Program administered by the Louisiana
Department of Environmental Quality (LDEQ).
To address monitoring of nutrients in point source discharges, LDEQ developed the Point Source
Implementation Strategy for Nutrients in the Louisiana Pollutant Discharge Elimination System (LPDES)
Program (LDEQ, May 30, 2017). LDEQ has begun implementing an enhanced approach for the
determination of nutrient monitoring for all discharges that might contain nutrients. Historically,
monitoring for nitrogen and phosphorus in LPDES general and individual permits has been implemented
based on TMDL determinations and in wetland assimilation projects and in practices such as requiring
B-10
-------
the use of low-phosphate, low-surfactant soaps and detergents as part of the General Permit for
Discharges of Exterior Vehicle Wash Wastewater (LAG750000).
Beginning May 1, 2016, LDEQ implemented nutrient monitoring in all renewal and new Major and Minor
Individual Permits, including for POTWs and privately owned treatment works. This monitoring consists
of reporting the concentration (mg/L) and loading (lb/day) for TN and TP on a quarterly basis.
Beginning in May 2017, nutrient monitoring has been implemented on a case-by-case basis for process
wastewater discharges from industrial facility types including food processing, petroleum refineries,
sugar production, sugar mills, sugar refineries, paper mills, animal farming operations, fertilizer plants,
wood processing, landfills, and any other facility where it is determined that there is the potential for a
high level of nutrient discharge. Monitoring might also be established at industrial facilities on a case-by-
case basis for other wastewater types such as stormwater or washwater if it is determined that these
discharges may be a source of nutrients. This monitoring consists of reporting the concentration (mg/L)
and loading (lb/day) for TN and TP on a semiannual basis or more frequently if conditions warrant.
Currently there are approximately 13,284 permitted dischargers in the state. Table B-5 lists the total
number of facility outfalls that have nutrient monitoring or limitations by facility type.

B.6 Minnesota Supplemental Information
Minnesota's Wastewater Phosphorus Reduction Strategy
The significant statewide effluent phosphorus load reductions by Minnesota WWTFs over the last 15
years have been achieved as the result of a long-term strategy (Figure B-2). Phosphorus monitoring has
increased over the last two decades and 55 percent of domestic and 9 percent of industrial NPDES
permits contain phosphorus limits. Further reductions are expected as a result of the implementation of
effluent limits consistent with Minnesota's river eutrophication standards.

B-12
-------
The majority of the phosphorus reductions can be traced back to the implementation of the Minnesota
Pollution Control Agency (MPCA) 2000 Phosphorus Strategy, which was developed by MPCA staff to
provide a consistent framework for implementing 1 mg/L TP limits and to promote reductions in
phosphorus loading from point sources. The MPCA Citizens' Board approved the strategy in March 2000,
establishing a 1-mg/L effluent concentration performance standard for new and expanded WWTPs
whose discharge had the potential to exceed 1,800 pounds per year and required smaller WWTPs to
develop Phosphorus Management Plans.
The majority of the statewide reduction in phosphorus discharge occurring from 2001 to 2013
(compared to peak loads pre-2001) was accomplished by the largest dischargers (Figure B-3), but
significant reductions have also been made by smaller facilities since 2008.
Reductions from 2000/01 to 2018:
Metropolitan Council WWTFs-838 metric tons (MT) per year = 77-percent reduction
Other major facilities367 MT per year = 21-percent reduction
Minor facilities63 MT per year = 30-percent reduction

Figure B-3. Minnesota NPDES discharger effluent TP loading trend by facility size.
MPCA's 2000 Phosphorus Strategy was formalized as Minnesota Administrative Rule 7053.0255 in
connection with the adoption of Lake Eutrophication Standards (LES) in 2008. Subsequent acceleration
in the development of water quality-based LES effluent phosphorus limits has resulted in further
effluent phosphorus load reductions. The adoption of River Eutrophication Standards (RES) in 2014 is
expected to further reduce Minnesota effluent phosphorus loads over the next decade. The overall
magnitude of RES-based reductions is expected to be small in comparison to the major statewide
progress made since 2000, but the results will be important for the health of local water bodies, and the
removal costs of those reductions may be relatively high where advanced tertiary treatment is
necessary to comply with low-level effluent phosphorus limits.
B-13
-------
As of April 2019, 76 percent of Minnesota's NPDES permits for dischargers in the Mississippi/Atchafalaya
River Basin (MARB) contain TP monitoring requirements and 36 percent of the permits contain effluent
limits (Table B-6).

Overall Minnesota estimates that implementing the 2000 Phosphorus Strategy and subsequent
adoption of Minnesota's Phosphorus Rule and LES have resulted in dramatic reductions in the quantities
of phosphorus discharged by Minnesota industrial and domestic WWTFs.
MPCA completed an NRS in 2014 to address nutrient impairments, which is available at
https://www.pca.state.mn.us/water/nutrient-reduction-strategy.
Point sources in the Mississippi River drainage have significantly reduced phosphorus loading since
2005. NRS phosphorus reduction goals for the Mississippi River have been achieved and substantial
progress has been made toward achieving Lake Winnipeg goals (Figure B-4). Point sources have not
achieved NRS nitrogen reduction goals (Figure B-5). Permit-required monitoring frequencies for nitrogen
species are being increased to develop a more comprehensive understanding of nitrogen in levels in
wastewater effluent.

B.7 Mississippi Supplemental Information
Through the NPDES Permitting Program, Mississippi has been implementing nutrient monitoring and/or
limits for TN and TP based on the following criteria:
Effluent monitoring of TN and TP for all municipal NPDES permits for facilities discharging more
than 1.0 MGD.
Influent monitoring of TN and TP for all municipal NPDES permits for facilities discharging more
than 1.0 MGD.
Effluent limits for TN and/or TP for NPDES permits for facilities discharging into receiving waters
that have nutrient TMDLs.
In addition, as part of the municipal separate storm sewer system process, Mississippi is requiring
entities to incorporate nutrient reduction strategies into their stormwater management plans. Figure
B-6 provides maps showing permitted facilities with nutrient (TN and TP) monitoring requirements and
TN and TP limits for their discharges, which drain into the Mississippi/Atchafalaya River Basin (MARB)
B-16
-------
Note: Data used to generate the maps came from a June 2019 ICIS data retrieval and differ slightly from
the September 30, 2017, ICIS data used to generate the summary information provided for Mississippi in
Table A-14. Since 2017, all major sewage treatment plants in MS now monitor for nutrients and there
has been an increase in the number of these facilities that have limits for TN and TP.
TP limits (right),
TMDL and Modeling
Mississippi has 97 water bodies with TN and/or TP TMDLs for waters that flow into the MARB. If a facility
discharges into a watershed with a nutrient TMDL, the facility is required, at a minimum, to monitor
their discharge for nutrients. Based on the TMDL loading requirements, the facility also might be
required to have nutrient limits. Additionally, as intensive water quality models are developed,
calibrated, and verified for state waters, and data of sufficient quality and quantity exist, model outputs
are being used to provide nutrient limits for new and expanding dischargers. Figure B-7 provides a map
showing waters with TN and/or TP TMDLs that flow into the MARB.

B.8 Missouri Supplemental Information
Data Collection Efforts in Missouri
The Missouri DNR is working toward better understanding Missouri's nutrient contributions through
data collection and analysis. An increasing number of point sources will be required to sample and
report nutrient discharges. Missouri revised its effluent regulation in 2014 to require facilities with
design flows of more than 100,000 gallons per day (gpd) to monitor discharges for TP and TN quarterly.
Those monitoring requirements are being incorporated into permits as they are renewed.
Currently, Missouri DNR permits 407
domestic WWTF with design flows of
more than 100,000 gpd. Of those, 257
facilities (or 63 percent) sample TP and/or
TN as a result of either monitoring
requirements or effluent limits in their
permits (Figure B-8). Missouri DNR is on
track to have permits for all 407 facilities
require nutrient monitoring by the end of
2019.

facilities make up 82 percent of the
total number of facilities, they
contribute only 3 percent of the
total daily flow (Figure B-9).
Figure B-9. Percent of total flow from domestic facilities with
design flows more than 100,000 gpd.
In addition to collecting data from point source dischargers, Missouri DNR collects surface water data
from multiple sources statewide. Along with nutrient data collected by the department's Monitoring
and Assessment Unit, the University of Missouri's Statewide Lake Assessment and Lakes of Missouri
Volunteer Program samples and provides lake nutrient data to the department (Figure B-10). Other
nutrient data sources include U.S. EPA and USGS.
Figure B-10. Nutrient monitoring sites for lakes and streams in Missouri.
B-19
-------
Nutrient Effluent Limitations in Missouri's Permits
Nutrient effluent limitations may be included in permits based on the following conditions:
Missouri's effluent regulation requires dischargers to two of the state's major lake watersheds,
Table Rock Lake and Lake Taneycomo, not to exceed 0.5 mg/L of phosphorus as a monthly
average. Facilities permitted prior to May 9, 1994, and with a design flow less than 22,500 gpd
are exempt from this requirement; however, aii dischargers in the area are required to monitor
for phosphorus.
Missouri's WQS contain numeric nutrient criteria for specific lakes, each of which have site-
specific criteria for TP, TN, and chlorophyll a.
Industrial dischargers might be subject to federal effluent guidelines.
Facilities discharging to an impaired water body might be subject to nutrient wasteload
allocations established in a TMDL. In those cases, effluent limitations could be calculated from
the wasteload allocations.
Numeric nutrient criteria for lakes and reservoirs were adopted as part of Missouri's WQS Rule
in 2009. In August 2011, U.S. EPA denied approval of a substantial part of that rule, expressing
some technical concerns with the criteria that were introduced. Missouri DNR has worked to
address those concerns and promulgated WQS in April 2018 that include numeric nutrient
criteria for lakes and reservoirs by ecoregions. EPA approved the new criteria in December 2018.
Conversion of Lagoons to No-Discharge Irrigation Systems in Missouri
Missouri DNR encourages wastewater treatment systems to achieve no-discharge to address more
stringent WQS and effluent limitations. Twenty-
five percent of the construction permit
applications received by the department from
2013 through 2016 were for the construction of
no-discharge facilities. The department offers no-
discharge guidance through its No-Discharge
Wastewater Treatment website at
https://dnr.mo.gov/env/wpp/no-discharge.htm.

Missouri's Nutrient Loss Reduction Strategy
The Missouri Nutrient Loss Reduction Strategy
uses an adaptive approach to reducing nutrient
pollution from both point and nonpoint sources
(Figure B-ll). The strategy proposes a set of
recommended actions intended to improve water
quality in Missouri while also reducing nutrients
transported downstream to the Gulf of Mexico.
The following recommended actions in the
strategy have been completed and are now being
implemented:

Over 50 point sources have proactively engaged in the Voluntary Early Nutrient Monitoring
Program by reporting monthly nutrient data to Missouri DNR.
After adoption by the Missouri Clean Water Commission in 2016, the Missouri Water Quality
Trading Framework now serves as the department's policy statement on WQT.
The Community Assistance Program was established in 2016 and provides support and coaching
to local governments to help them make informed decisions about environmental protection for
their community. Coordinators are staffed in each of Missouri DNR's regional offices to enable
them to work closely with communities and provide easy access to assistance and resources.
B.9 Ohio Supplemental Information
Tracking Nutrient Loads
In 2015, the Ohio General Assembly passed Amended Substitute House Bill 64 that contained a
requirement for the Ohio Environmental Protection Agency (OEPA) to prepare a biennial report on mass
loading of nutrients delivered to Lake Erie and the Ohio River from Ohio's point sources and nonpoint
sources (Ohio Revised Code 6111.03(U)). In April 2018, the second edition of the Nutrient Mass Balance
Study for Ohio's Major Rivers was completed for nine watersheds in Ohio covering 66 percent of the
state's land area. The watersheds studied were in both the Lake Erie and Ohio River drainages. The
objective of the study was to determine nutrient (phosphorus and nitrogen) loads and relative
proportions of point and nonpoint sources. The study highlights differences between the watersheds
both as total loads and relative contributions from different sources in the watersheds. The study
identifies opportunities for data collection and new approaches that can refine future analysis on a
biennial basis. This study, along with the other data related to current and past nutrient loadings, can
serve as a tool to focus research, investment, and policy/legislation decisions to curb phosphorus and
nitrogen loading in both the Lake Erie watershed and the Ohio River basin. The 2018 study is available
on OEPA's website at
https://epa.ohio.gov/Portals/35/documents/Nutrient%20Mass%20Balance%20Studv%202018 Final.pdf.
Technology Upgrade Feasibility Studies
In 2015, the Governor signed into law Ohio Senate Bill 1, which required POTWs with a design flow of
1.0 MGD or more, or otherwise designated as a major sewage treatment plant by the Director of OEPA,
and that did not have limits for TP to submit a study evaluating the technical and financial capability of
the facilities to reduce the final effluent discharge of phosphorus to 1.0 mg/L. The language in the bill
was later incorporated into Ohio Revised Code 6111.03. The studies were required to be submitted to
OEPA no later than December 1, 2017. Ohio had 100-percent compliance with the study requirement,
with 112 reports received. The information contained in the reports informed rulemaking efforts to
support a statewide TP discharge limit of 1.0 mg/L for all major POTWs.
Legislative Efforts
Currently, there isn't legislative support for a statewide TP discharge limit. However, in 2019, Governor
DeWine signed H.B. 7, creating a water quality initiative known as H20hio. This initiative consists of a
trust fund for the protection, preservation, and restoration of Ohio's water quality. Through
collaboration among the Ohio Department of Natural Resources, Ohio Environmental Protection
Agency, Ohio Department of Agriculture, and Ohio Lake Erie Commission, the H20hio Fund will provide
additional resources to plan, develop, and implement targeted water quality initiatives and best
B-21
-------
management practices that will minimize the introduction of nutrients and other runoff into Ohio
waterways. The bill also supports additional staffing at soil and water conservation districts, and more
aggressive action to address failing septic systems and other water treatment needs across Ohio. For
more information about H20hio, see http://h2.ohio.gov/wp-content/pdfs/H20hio-Handout.pdf.
OEPA has actively engaged the Legislature to propose, as part of a larger rule package, a statewide
monthly average effluent limit of 1.0 mg/L for major WWTPs. While the Agency was unsuccessful in
identifying a sponsor to introduce the legislation in the spring/summer of 2018, it is committed to
continue to seek a sponsor for future legislative sessions.
OEPA began the process of drafting a large river eutrophication standard in August 2018 and solicited
public comments through an early stakeholder outreach effort to develop rule language. The rulemaking
effort will assist the Agency in determining when nutrients are impairing waterways and in setting
targets for nutrient levels in streams to achieve attainment. This rule development is currently on hold
while Ohio updates the Domestic Action Plan.
State Water Quality Trading Programs
OEPA adopted revised rules for WQT in May 2018. The revised rules incorporate the latest accepted
approaches to implementing a WQT program. They provide a framework for developing a WQT plan
that must be approved by the Director of OEPA before any trading activities can occur in Ohio.
Ohio continues to have several approved trading programs and pilot programs, with the most active
being the Alpine Dairy WQT management plan and the Electric Power Research Institute's Ohio River
Basin Trading Project. Ohio has also started developing a stewardship credit trading program to
encourage investment in nonpoint source load reductions. In June 2018, OEPA shared a draft
memorandum of understanding with possible trading partners and is currently working through the
comments received.
B.10 Tennessee Supplemental Information
Since September 2017, Tennessee has made additional progress in reducing point source nutrient
loading. As of March 2019, many facilities had added new nutrient monitoring requirements and/or
discharge effluent limits. The Tennessee Department of Environment and Conservation updated
Tennessee's table in Appendix A (Table A-19) to include the newly instituted updates, as shown in Table
B-7, marked with a double dagger (t).

B.ll Wisconsin Supplemental Information
Phosphorus
Wisconsin has a long history of protecting its surface waters from excess phosphorus pollution. The
state implemented normal regulations in 1992 for wastewater point source discharges, requiring many
Wisconsin Pollutant Discharge Elimination System (WPDES) permit holders to comply with technology-
based effluent limits (TBELs), typically set equal to 1.0 mg/L (Wisconsin Administrative Code [Wis. Adm.
Code] chapter NR 217 subchapter II). Additionally, Wisconsin has implemented priority watershed
projects throughout the state to help reduce nonpoint source pollution to meet water quality goals. A
full description of these and other historic phosphorus efforts is provided at
http://dnr.wi.gov/news/mediakits/mk phosphorus.asp.
To further protect human health and welfare from excess phosphorus pollution, the following revisions
to Wisconsin's phosphorus WQS for surface waters were adopted on December 1, 2010:
Establishing the maximum allowable phosphorus concentration in Wisconsin's waters, also
known as phosphorus criteria (Wis. Adm. Code s. NR 102.06 ) (Table B-8).
Creating phosphorus standard implementation procedures for WPDES permits (Wis. Adm. Code
ch. NR 217 subchapter III).
Strengthening agricultural performance standards to help curb nonpoint source phosphorus
pollution (Wis. Adm. Code ch. NR 151).10
Since December 2010, the Wisconsin Department of Natural Resources (WDNR) has been evaluating the
need for phosphorus water quality-based effluent limits (WQBELs) in WPDES permits to comply with
these standards. Wisconsin's Phosphorus Implementation Guidance provides a detailed discussion of
the phosphorus standards and implementation procedures in WPDES permits, and is available for
download at http://dnr.wi.gov/topic/surfacewater/phosphorus.html.
Many point sources face restrictive phosphorus limitations under these standards. Almost 80 percent of
wastewater permittees face more restrictive phosphorus limits than Wisconsin's TBEL of 1.0 mg/L.
Under NR 217, 60 percent of those facilities will receive phosphorus WQBELs set equal to the
phosphorus criteria shown in Table B-8.11 The remaining point sources are given less restrictive limits
based on the assimilative capacity of the receiving and/or downstream surface water; however, WQBELs
consistent with TMDLs can be used in lieu of the NR 217-derived limits.
WQBELs derived through NR 217 target only the point source fraction of phosphorus loading entering
Wisconsin surface waters. In most watersheds, compliance with water quality criteria requires
addressing both point and nonpoint sources of phosphorus. Figure B-12 highlights the ratio of point to
nonpoint phosphorus mass loads for HUC 8 watersheds within the MARB. Figure B-12 summarizes TP
loads on an annual basis. To express needed mass reductions from both point and nonpoint sources of

phosphorus, Wisconsin relies on the development of TMDLs and water quality protection and
restoration plans.
Wisconsin develops TMDLs by evaluating phosphorus loads on a monthly basis to account for the
seasonal variation in the loadings, to ensure adequate protection during critical periods, and to ensure
allocations correspond with the compliance periods for the phosphorus criteria and delisting protocols
for the Clean Water Act (CWA) section 303(d) list of impaired waters.12 TMDLs produce both wasteload
and load allocations needed to attain WQS. The wasteload allocations are implemented through NR 217,
and the load allocations are implemented through NR 151. Figure B-13 highlights the completed TMDLs
currently in the implementation phase, the reaches currently listed as impaired for phosphorus, and the
prioritization for future studies.

Implementing point source reductions is handled through the WPDES Permit Program, with issued
permit limits consistent with allocations contained in the TMDL. Nonpoint sources are addressed
through implementing the performance standards and prohibitions contained in NR 151. Typically, an
offer of state or federal cost-sharing is required to implement the nonpoint practices. To help address
shortfalls in funding for nonpoint source reductions and help offset the often-costly point source
reductions, WDNR, in collaboration with its stakeholders, developed innovative compliance options as
part of the 2010 phosphorus rulemaking for reaching water quality goals in a more economically
efficient manner. That action spurred the development of Wisconsin's adaptive management (AM) and
WQ.T programs. Making the compliance options available enables point source dischargers to invest a
smaller amount of money toward nonpoint source pollution control projects and potentially have a
greater water quality benefit.13 These programs are considered a viable solution for many point sources
working toward phosphorus compliance.

-------
Although the two programs are similar, AM projects and WQT projects are different. In both cases, point
sources can take credit for phosphorus reductions within the watershed toward phosphorus
compliance. Because the practices used to generate phosphorus reductions might be the same, the
compliance options are often confused with one another. AM and WQT projects have different permit
requirements as well as different timing requirements:
Different end goals. AM projects focus on achieving water quality criterion for phosphorus in
the surface water; WQT projects focus on offsetting phosphorus from a discharge to comply
with a permit limit.
Monitoring, Because AM projects focus on water quality improvements, in-stream monitoring is
required under AM; it is not required under WQT.
Timing. Practices used to generate reductions in a WQT strategy must be established before the
phosphorus limit takes effect; AM is a watershed project that can be implemented throughout
the permit term.
Quantifying reductions needed. Under Wisconsin's WQT policy, WQT requires trade ratios to be
used to quantify reductions used to offset a permit limit; the reductions needed for AM are
based on the receiving water, not the effluent, and trade ratios are not necessary in the
calculation.
Eligibility. The AM and WQT programs have different eligibilities.
Many point sources are developing and/or implementing WQT or AM projects to seek phosphorus
compliance in lieu of installing treatment technologies (Figure B-14). Information about these and other
projects is available at http://dnr.wi.gov/topic/SurfaceWater/AmWqtMap.html. WDNR anticipates that
AM and WQT projects will continue to be developed over the next 5-10 years as point sources make
compliance decisions for phosphorus.

-------
As of late 2018, over 30 WPDES permittees statewide had selected WQ.T or AM as a phosphorus
compliance option. Wisconsin mandates that all WQ.T projects result in an improvement in water
quality. They represent environmentally and economically beneficial compliance solutions. Phosphorus
reductions used for compliance are quantified using best-available modeling technology as well as a
trade ratio to account for factors such as downstream delivery and practice uncertainty. Despite the
widespread need and relatively low costs associated with installing nonpoint BMPs, some common
hurdles have been identified during project development. In some instances, industrial or municipal
wastewater treatment operations are not readily equipped to work at a watershed scale to implement
nonpoint source phosphorus reductions. A greater degree of uncertainty is associated with relying on
BMPs for compliance than is associated with a facility upgrade. Spending pollution control dollars
outside the facility also might be controversial in some situations. To address some of those challenges,
the conservation community has formed a variety of partnerships. Local environmental organizations
such as county land and water conservation departments, watershed and agricultural groups, and other
nongovernmental organizations have begun partnering with point sources to implement compliance-
driven projects. These projects range from native prairie restoration on a single farm field to regional
nutrient reduction initiatives fueled by discharger resources. Many of the projects have the potential for
added value through positive publicity consistent with increased corporate responsibility and facility
rebranding occurring across the wastewater industry.
Despite these additional options, some facilities have found that compliance with restrictive phosphorus
limitations is simply not economically feasible. In those cases, point sources might seek an individual
phosphorus variance based on substantial and widespread social and economic impacts. Facilities with
an approved variance might be allowed to discharge higher concentrations of pollutant for a period, but
also must commit to making strides towards reducing effluent phosphorus and achieving compliance
with the final limit. These strides are outlined in a pollutant minimization plan and can be tailored to the
facility's unique situation.
Because of the expected increase in phosphorus variances associated with the 2010 rule change and the
opportunities for watershed-based offsets, a multidischarger variance (MDV) for phosphorus was
established to help streamline and improve the variance process. Wisconsin enacted the concept of a
multidischarger phosphorus variance in Wis. Adm. Code s. 283.16 in 2013, and U.S. EPA approved it in
2017. The MDV allows a discharger 5-20 years to comply with restrictive phosphorus limits, while
making meaningful contributions to local water quality. During the variance term, point sources are
required to optimize their treatment processes for phosphorus, make stepwise reductions in effluent
phosphorus concentrations, and implement a watershed project.
Similar to the pollutant minimization plans for individual variances, a MDV watershed plan is designed to
make economically feasible reductions in phosphorus entering surface waters of the state. There are
three types of watershed projects for the MDV. The point source discharger has the discretion to select
the option that works best for it:
The discharger can make payments to county land and water conservation departments located
in the same HUC 8 basin in the amount of $50 per pound times the difference between what it
discharges and a target value. Payments are capped for any one point source at $640,000 per
year.
B-31
-------
The discharger can enter into an agreement with WDNR to implement a plan or project
designed to result in an annual reduction of phosphorus from other sources in the HUC 8 basin
in an amount equal to the difference between what it discharges and a target value.
The discharger can enter into an agreement with a third party that is approved by WDNR to
implement a plan or project designed to result in an annual reduction of phosphorus from other
sources in the HUC 8 basin in an amount equal to the difference between what it discharges and
a target value.
As of late 2018, 54 point sources have been approved for coverage under the MDV (Figure B-15). The
vast majority of MDV watershed plans use the county payment option. As a result, an estimated
$900,000 will be available to county land and water conservation departments in 2019.
WDNR expects to see similar funding levels in future years, increased because of additional dischargers
seeking coverage under the MDV, but reduced payments for those already enrolled because of their
phosphorus optimization efforts. An established planning and reporting process for counties electing to
receive MDV dollars defines expectations for projects funded through the program. At a minimum, 65
B-32
-------
percent of the funds must be spent on implementing Wisconsin's NR 151 agricultural performance
standards. Many facilities enrolled in the MDV program are working toward compliance through trading
or AM over a longer time frame.16
Nitrogen
It is common practice for Wisconsin to include TN limitations in WPDES permits for groundwater
discharges to ensure that drinking water standards are maintained in water supplies. That is not the
case, however, for WPDES permits for surface water discharges at this time. Wisconsin does not have
numeric TBELs or WQS for TN. Therefore, TN permitting decisions for surface water discharges are based
on narrative standards. In-stream monitoring throughout Wisconsin continues to be conducted to help
determine if surface water quality is being adversely affected by excess TN and, if so, where the
deleterious effects are occurring. In addition, WDNR has expanded the effluent monitoring
requirements for TN in WPDES permits to gather additional information about TN effluent
concentrations across the state. Those efforts have improved WDNR's ability to evaluate the need for
restrictive TN limitations in WPDES permits but have not resulted in restrictive TN effluent limitations
being included in WPDES permits so far.
Several phosphorus-based regulatory programs will also help curb TN pollution. Nonpoint source
practices installed through WQT, AM, and the proposed multidischarger phosphorus variance will
reduce phosphorus and nitrogen pollution entering surface water. Additionally, WDNR is currently
developing a robust tracking system to retain information about BMPs installed and phosphorus,
nitrogen, and total suspended solid pollution reduced as a result of these and other programs
throughout the state.
Impaired Waters
The goal of the CWA is "to restore and maintain the chemical, physical, and biological integrity of the
Nation's waters" (Title 33 of the United States Code §1251(a)). CWA section 303(d) requires states to
publish a list every 2 years of all waters that do not meet WQS. The law requires that states establish
priority rankings for waters on the list and develop TMDLs for those waters. An essential component of a
TMDL is calculating the maximum amount of a pollutant that can occur in a water body that still allows
that water body to meet WQS.
Tackling excess nutrients in our waterways is especially challenging in the 303(d) program for most
states, in part because most states rely on narrative WQS on which to base impairment decisions.
Wisconsin adopted numeric phosphorus criteria for streams, rivers, and lakes in 2010, however, and can
readily apply those criteria to listing a water body, identifying nutrients as the cause of the impairment,
and establishing water quality targets for TMDLs.
The listing process has led to the identification and tracking of approximately 1,535 impaired waters
throughout Wisconsin (Figure B-16). Of those, 921 waters are impaired by excess levels of phosphorus.
TMDLs are currently in development to address 155 of the phosphorus listings, and TMDLs have been
approved by U.S. EPA that address 111 phosphorus listings. WDNR is currently working with multiple
stakeholders on developing TMDLs for the restoration of HUC 12 watersheds identified as high priority

on the current impaired waters list. A TMDL was developed for the Wisconsin River watershed to
address nutrient- and sediment-related impairments in that watershed. EPA approved the TMDL in April
2019.

-------
Addressing nutrient pollution in Wisconsin's waters is a top priority for WDNR's impaired waters
program. WDNR revamped its TMDL development prioritization framework in 2015 to incorporate a
systematic and objective modeling analysis that identifies watershed areas experiencing the most
ecological degradation and vulnerability to future degradation and focuses planning efforts on two
pollutants: TP and total suspended solids.
Following TMDL implementation, expectations are often high for an impaired water's condition to begin
to change. The TMDL program analysis focuses on approaches for detecting improving conditions and
identifying driving factors associated with improvements. A water body remains on the 303(d) list until it
is fully recovered and meets WQS. Since 2002, Wisconsin has delisted 180 individual streams, lakes, and
beaches, representing approximately 600 stream miles and 59,000 lake acres. Most of the delisted
impairments to date, however, have not been related to eutrophication.
