Farewell to Nonpoint Source News-Notes

It s a bittersweet moment. After 102 issues and 29 years, the U.S. Environmental Protection Agency (EPA) will cease
publication of Nonpoint Source News-Notes. This is the final issue, although the archived issues will remain available
on EPA's News-Notes website. We dedicate Issue #102 to Harold (Hal) Wise (1917—1994), who founded News-Notes in
1989 near the tail of a storied career where he became known as the father of state planning. For more insights on the
impact Hal had on the environment and on his friends and colleagues,
read "A Tribute to a Wise Man" in News-Notes Issue 36. As Hal noted
in the introduction to the very first issue, News-Notes was intended to
"highlight and report what is happening in those states that are tackling
the management of nonpoint sources of pollution and the improvement
of water quality," and that it would feature "reports on significant EPA
and other federal agency activity, as well as private, corporate and citizen
group contributions." The writers and editors of News-Notes have faith-
fully followed his vision ever since. Thank you, Hal.

We are grateful to Hal Wise, father of NPS

Notes on the National Scene

Green Infrastructure in Parks: Encouraging Community-Based Partnerships

Public park land and other green spaces serve their surrounding communities in many ways—
providing recreational outlets, offering peaceful places for respite and reflection, preserving the
environment, and often protecting water quality To help managers realize their parks' full potential,
the U.S. Environmental Protection Agency (EPA) recently released Green Infrastructure in Parks: A
Guide for Collaboration, Funding, and Community Engagement. The guide is intended to encourage
partnerships between park agencies and stormwater agencies to improve park lands, increase access
to parks, better manage stormwater, increase community resiliency to changing weather patterns,
and provide funding to implement and maintain park enhancements that benefit communities.

The guide is designed to help stakeholders collaborate to use green infrastructure to
improve park lands. The sections walk readers through the multistep process of:

•	Identifying and engaging partners, such as elected officials, park superintendents,
stormwater utility managers, water regulatory agencies, or staff from departments of
conservation or natural resources.

•	Building relationships and collaborating to identify common goals.

•	Leveraging funding opportunities such as mutually beneficial funding partnerships
with water providers, stormwater utilities and watershed groups.

•	Identifying green infrastructure opportunities, looking for ways to restore riparian
areas and areas with well-draining soil to capture and treat runoff from impervious
surfaces and other drainage areas.

•	Planning for maintenance, including identifying necessary tasks, funding sources,
and agencies' specific roles and responsibilities over the long term.

•	Undertaking high-visibility projects to garner support from the community for
additional green practices.

Case studies are included to illustrate the approaches presented in the guide. These
real-life examples portray how partnerships between municipal stormwater agencies and
parks departments have improved recreational resources in the community, enhanced environmen-
tal protection, and reduced risks and burdens. For those who wish to go deeper into a topic, the
guide includes short descriptions and links to external resources that provide more detail on the
material presented within.

Clearinghouse Helps Communities Finance Water Projects

Are you looking to upgrade your community's water resources infrastructure and make other
improvements to protect your local waters? The U.S. Environmental Protection Agency's (EPA's)
Water Finance Center developed the web-based Water Finance Clearinghouse (Clearinghouse)
portal (www.epa.gov/wfc) to connect communities with funding sources and financing resources.
The Clearinghouse provides communities with searchable databases featuring more than
$10 billion in potential water funding sources and more than 600 water finance resources (e.g.,
reports, tools, case studies) to support local water infrastructure and watershed protection projects.

The Clearinghouse consolidates and expands upon existing EPA-supported
databases to create a one-stop-shop that serves all community water finance
needs. Several separate resource- and funding-related databases have been
rolled into the new Clearinghouse, including EPA's Catalog of Federal
Funding Sources for Watershed Protection, EPA's Federal Funding for
Water and Wastewater Utilities in National Disasters (Fed FUNDS), and
the Environmental Finance Center Network's Funding Sources by State
factsheets. The content of the Clearinghouse emphasizes financing, funding,
and capacity development, and all linked-to resources are free of charge. The

information provided through the Clearinghouse helps communities make financing decisions for
watershed protection and their specific drinking water, wastewater, stormwater and green infra-
structure needs.

"Communities need easy and efficient access to water infrastructure finance information," explains
Kristyn Abhold, a financial analyst with EPA's Water Finance Center (Center). "Before the
Clearinghouse was launched, the Center had to direct communities seeking water finance informa-
tion and funding sources to multiple websites. It was time-consuming and difficult for communi-
ties to locate information. The Center developed the Clearinghouse to meet this
need. The Clearinghouse is a one-stop-shop for all things water finance."

How Does the Clearinghouse Work?

The Clearinghouse features two searchable databases: Resources and Funds.
The Resources database contains reports, tools, webinars, case studies and
other resources offering information about water financing mechanisms and
approaches. The Funds database contains federal, state, local, nongovernmental
organization, and some private funding sources that are available to support
water infrastructure and watershed protection projects. The Clearinghouse cur-
rently contains nearly 600 resources and funding sources specifically focused on
stormwater and green infrastructure financing.

You can search for specific financial information by state, region, community
population size, keyword, sector (e.g., agriculture, green infrastructure, septic/
decentralized), funding source, financing approach, author and resource type.
By applying multiple filters, you can narrow dowm the results and find specific
information that meets your needs. Search results can be sorted by column
heading, marked as a favorite, saved for later, and can be exported to Excel
with the hyperlink to the specific resource(s). Users can create a General User
account to view saved searches and subscribe to receive notifications when new
resources and funding sources are added to the Clearinghouse.

How Often Will the Clearinghouse be Updated?

The Clearinghouse is updated in real-time. States, federal agencies, and other water sector stake-
holders may suggest edits or the addition of new resources or funding sources at any time by
creating a Clearinghouse Contributor account. This is especially valuable for users who are part of
funding networks who routinely publish or produce water finance-specific resources and/or those
that manage water funding sources. Stakeholders can use this interactive feature to manage how
their programs and initiatives are displayed in the Clearinghouse, and they can edit and verify that

their content is accurate and complete. In addition
to content review by Contributors, EPA plans to
review and update content annually.

The Water Finance Center is soliciting feedback
on Clearinghouse content and functionality from
funding agencies and users. EPA has been conduct-
ing outreach to major water associations through
postings on numerous listservers, through a series
of webinars, and by attending and presenting at
numerous conferences. Since the Clearinghouse's

Report Outlines Tools to Protect Aquatic Life from Hydrologic Alteration

Do you know the extent to which human activities and unpredictable weather events can harm
aquatic life? Do you need suggestions on how to protect your streams from extreme weather
events? In December 2016 the U.S. Environmental Protection Agency (EPA) and the U.S.

Geological Survey (USGS) released a joint technical report, Protecting Aquatic Life
from Effects of Hydrologic Alteration, to help you with these questions. The authors
explain how changes in natural flow systems can harm aquatic ecosystems, and then
present example narrative water quality assessment criteria and outline strategies that
states, tribes and territories can use to asses and protect waterways.

Landscape and water management modifications such as dams, urban development,
and agricultural practices are causing changes in the magnitude and frequency of
flood flows and base flows, peak flow timing, and other flow characteristics in U.S.
streams and rivers. Some activities directly add or remove water from streams and
cause flows to be unusually high or low for long periods of time. Adding to the chal-
lenge, in many places weather is becoming more unpredictable (e.g., more frequent
extreme weather events, including droughts and lower-than-normal snow pack
thickness).

How Does Hydrologic Alteration Affect Aquatic Life?

A water body's ability to support aquatic life depends on water flow and dependable

•	Changes in water conditions. Altered flow can lead to changes in water chemistry,
sedimentation and temperature.

•	Ecosystem disconnection. Stream flow variability can affect the upstream—downstream
properties of a natural stream, changing the connections between surface water and
groundwater and also between areas of high-quality habitat.

•	Life cycle interruption. Streams with altered flows can fail to provide the flow-based cues or
signals needed by aquatic species to prompt them to complete their life cycles (e.g., flow-
directional cues that indicate which way and when to migrate), thereby disrupting successful
reproduction.

•	Invasive species introduction. Flow changes can allow invasive and non-native aquatic species
to become established within the aquatic system, which can displace native species.

Report Offers Example Water Quality Criteria and Flexible Framework for Water Resource
Managers

To help water resource managers plan ahead to protect their local waters from the potential nega-
tive effects of hydrologic alteration, the report provides 10 examples of narrative water quality
standards that states and tribes have adopted. The narrative language addresses the type of resource

to be protected and/or the protection goal. It also provides one
or more statements describing the hydrologic condition needed
to be maintained to achieve the protection goal.

The report also presents a flexible framework that states and oth-
ers can use to establish quantitative flow targets. Incorporating
EPA's Guidelines for Ecological Risk Assessment, the framework
consists of eight steps, beginning with how to identify biological
goals and assessment endpoints and ending with how to evaluate
effects on aquatic life under varying degrees of flow alteration.
The framework first focuses on the processes and information
needed to evaluate relations between flow and aquatic life. It
then leads readers through the development of narrative or
numeric flow targets that can be used in a state water quality
management program.

For more information see EPA's Final EPA/USGS Technical Report: Protecting Aquatic Life from
Effects of Hydrologic Alteration Documents website, which includes a link to the full document, a
fact sheet, and public and peer comment response documents.

Special Focus: Nutrient Poiiution and Algal Blooms

Summer 2017 Gulf of Mexico Hypoxic Zone Was Largest in Recorded History

Scientists have determined that the summer 2017 Gulf of Mexico's hypoxic zone, sometimes
referred to as the "dead zone," was the largest measurement since mapping of the zone began in
1985. This zone, an area of low-oxygen water (less than 2 ppm) that cannot sustain fish and marine
life, covered 8,776 square miles (mi2)—an area roughly equal to the size of New Jersey. Each

year, the Mississippi and Atchafalaya rivers carry enormous loads of
wastewater from cities in the American heartland and nutrients lost
from millions of acres of farm fields to the northern Gulf of Mexico.
These nutrients feed large algal blooms that, in turn, cause a hypoxic
(low oxygen or "dead") zone to form in bottom waters of the Gulf of
Mexico. Much of the nutrient losses to the Gulf occur during heavy
rains and floods. In very wet years like last year, the hypoxic zone
is far larger than its average size. In July 2017 the zone was about
50 percent larger than the 5,806-square-mile average measured over
the past five years, and was more than four times larger than the

What is Hydrologic Alteration?

Hydrologic alteration, or flow alteration, is a change to the
natural flow regime in a waterway or other aquatic system.
It can be further intensified by human activities and
unpredictable weather events, and can contribute to the
impairment of water bodies that are designated to support
aquatic life. Example sources of flow alteration include:

•	Dams and impoundments (including for hydropower)

•	Diversions (including for hydropower)

•	Groundwater withdrawals

•	Effluents and other artificial inputs

•	Land cover alteration

The Mississippi-Atchafalaya River Basin is the third largest in the world.

five-year average target size of approximately 1,900 mi2 established by the Mississippi River/Gulf of
Mexico Hypoxia Task Force.

VJhat Causes Gulf Hypoxia?

The Gulf of Mexico hypoxic zone, where dissolved oxygen is too low for many aquatic species
to survive, is fueled by nutrients (nitrogen and phosphorus) delivered from the Mississippi-
Atchafalaya River Basin and is also affected by stratification (layering) of waters in the Gulf
Nutrient-laden freshwater discharging from the Mississippi-Atchafalaya River is warmer and less
dense than the deep ocean water of the Gulf and tends to collect in an upper, less-saline surface
layer. This stratification of the water column restricts mixing of oxygen-rich surface water with
oxygen-poor deep water. Additionally, excess nutrients in the Gulf trigger an overgrowth of algae
that rapidly consumes oxygen when decomposed. This decomposition, coupled with water column

stratification, results in hypoxia. Mobile animals
(e.g., adult fish) can typically survive hypoxic
events by moving to areas of higher oxygen, but
this might push them into less optimal habitats,
often along the edge of the hypoxic zone. Less
mobile animals (e.g., clams, worms) that typically
constitute critical food sources for fish populations
cannot move to higher oxygen waters and are often
killed during hypoxic events.

Large 2017 Hypoxic Zone Was Forecasted

The wide extent of the summer 2017 hypoxic zone
was not unexpected. In June 2017 the National
Oceanic and Atmospheric Administration
(NOAA) had predicted that the size of the 2017
hypoxic zone would be larger than average because
the stream flows in May 2017 were about 34 per-
cent higher than the long-term average and carried
higher-than-average nutrient loads. The annual
NOAA-sponsored hypoxia forecast assumed typical
weather conditions and was modeled based on
nutrient runoff and river discharge data collected
by the U.S. Geological Survey (USGS) in spring
2017- Through its network of more than 3,000
real-time stream gauges and 60 real-time nitrate
sensors, the USGS tracks trends in nutrient loads
and concentrations throughout the Mississippi-
Atchafalaya River Basin, which drains parts or
all of 31 states (41 percent of the lower 48 states).
According to the USGS, data indicated that
approximately 165,000 metric tons of nitrate (about
2,800 train cars of fertilizer) and 22,600 metric
tons of phosphorus flowed down the Mississippi
and Atchafalaya rivers into the Gulf of Mexico in
May 2017- This nutrient influx was expected to fuel
large algae blooms, which in turn would lead to
low dissolved oxygen levels in the Gulf of Mexico.

July 2017 monitoring data confirmed the prediction of a large hypoxic zone. During a survey
mission in late July, a team of scientists led by partners at the Louisiana Universities Marine
Consortium (LUMCON) and Louisiana State University collected water quality data to determine
the size of the hypoxic zone. As reported by NOAA in an August 2, 2017, press release, LUMCON
found the actual measured hypoxic zone size in the Gulf of Mexico to be 8,776 mi"—even larger

Nutrient Sources Are Ubiquitous in the Mississippi River Basin and Nationwide

Nutrient pollution is one of America's most widespread, costly, and challenging environmental problems,
and is caused by excess nitrogen and phosphorus in the air and water. Addressing nutrients in surface
waters can be challenging because nutrients come from many diverse sources, including:

•	Agriculture: Animal manure, excess fertilizer applied to crops and fields, and soil erosion make
agriculture one of the largest sources of nitrogen, phosphorus and sediment pollution.

•	In and around the home: Fertilizers, yard and pet waste, and certain laundry and dishwashing
soaps and detergents contain nitrogen and phosphorus, and can contribute to nutrient pollution.
The amount of hard surfaces and type of landscaping on a property can also increase the runoff of
nitrogen and phosphorus during wet weather.

•	Stormwater: When precipitation falls on our cities and towns, it runs across hard surfaces—such as
rooftops, sidewalks and roads—and carries pollutants, including nitrogen and phosphorus, into local
waterways.

•	Wastewater: Our sewer and septic systems are responsible for treating large quantities of waste,
and some of these systems do not always operate properly or remove enough nitrogen and
phosphorus before discharging into surface waters. Even with advanced nutrient removal technology
in place at many wastewater treatment plants, not all nutrients can be removed before the effluent is
discharged to surface waters.

than the 8,185-mi2 zone that had been forecasted by NOAA in June 2017- The similarity between
predicted and measured hypoxic zone size emphasizes the strong link between the Mississippi
River nutrient runoff and the magnitude of Gulf hypoxia. "As algal blooms and hypoxia become
more widespread and their effects more pronounced, the USGS's long-term monitoring and real-
time sensors, coupled with watershed modeling, will continue to improve our understanding of
their causes and the role they play in the Gulf and in lakes and streams across the country," said
Don Cline, associate director for the USGS Water Mission Area.

What's Being Done to Combat the Nutrient Pollution that Fuels Hypoxia?

EPA is diligently supporting its partners to combat nutrient pollution in the Mississippi—
Atchafalaya River Basin and other U.S. watersheds through a series of activities, including con-
ducting outreach, developing partnerships, providing technical and programmatic support to
states, financing nutrient reduction activities, overseeing regulatory programs, conducting targeted
research and measuring progress.

NOAA funds multiyear monitoring and research projects in the Gulf of Mexico through
its Northern Gulf of Mexico Ecosystems & Hypoxia Assessment program, known as NGOMEX.
Current studies are documenting the dynamics of the hypoxic zone over the Louisiana continental
shelf and are better defining the biological, chemical, and physical processes that influence the
extent of hypoxic zone development and its impacts on fisheries.

For many years, EPA, its federal partners, and 12 states and tribal partners along the Mississippi
and Ohio rivers have worked together through the Hypoxia Task Force (HTF) to reduce the size
of the low oxygen zone in the northern Gulf Each state has a strategy for reducing its nutrient
loads. Federal agencies contribute financial, technical resources and scientific expertise, such as the
NOAA and USGS support described above. The HTF has quantitative goals for reducing nutrient
loads to the Gulf and tracks progress towards its goals. For more information on the HTF and its
ongoing work to reduce nutrient pollution, see the next article, Collaborative Nutrient Reduction
Efforts Target Gulf of Mexico Hypoxia.

Collaborative Nutrient Reduction Efforts Target Gulf of Mexico Hypoxia

Higher-than-average spring rainfalls and elevated nutrient loads in early 2017 contributed to a
summer 2017 Gulf of Mexico hypoxic zone that encompassed the largest area recorded: 8,776
square miles (mi2). Despite strong efforts, reducing nutrient loads from a vast landscape, where tens
of millions of people live and grow the food that feeds even more, is an extraordinarily large task.
The multiagency Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (Hypoxia Task
Force, or HTF), established almost two decades ago, collaborates to find and implement solutions
to the nutrient enrichment challenges in the Mississippi—Atchafalaya River Basin (MARB) and the
Gulf of Mexico.

In February 2015 the HTF announced that it would retain its previous size goal
of reducing the five-year average areal extent of the Gulf of Mexico hypoxic zone
to 1,900 mi2 by the year 2035. The HTF agreed on an interim target of a 20 per-
cent nutrient load reduction by the year 2025 as a milestone toward achieving the
final goal in 2035- The HTF also agreed to adopt quantitative measures to track
progress in reducing point and nonpoint source inputs. As noted in the HTF's
2017 Report to Congress, myriad partners are collaborating on projects and strategies
designed to achieve these goals.

The 2017 Report to Congress highlights the efforts and achievements of the HTF and
its partners as they work together to implement the Gulf Hypoxia 2008 Action Plan.
The 2017 report reiterates that HTF members believe the 2008 Action Plan continues
to provide a strong framework for reducing nitrogen and phosphorus in the MARB
and reducing the size of the Gulf hypoxic zone, mainly by implementing state-level
nutrient reduction strategies. The most effective approach to moving forward is for
the HTF to accelerate implementation of the activities that were specified in the 2008
Action Plan, while refining specific approaches as better science, new tools, and policy
innovations become available.

The 2017 report offers background information about hypoxia and water quality,
discusses the history of the HTF and its goals, and describes ongoing efforts such as
monitoring and modeling/forecasting (see box) that enable coastal resource manag-
ers, the HTF, and the HTF's partners to craft effective strategies and make informed
decisions. The report also highlights the HTF's partnerships with land grant universities and
others to reduce gaps in research and help conduct outreach, especially to the MARB's agricultural
community.

Since the release of the 2008 Action Plan, each HTF state has developed its own nutrient
reduction strategy with the help of stakeholders within each state. Each strategy acts as a road
map for achieving nutrient reductions in that state, and they collectively serve as the cornerstone
for reaching the HTF's overall goals. The 2017 report reviews recent HTF efforts to track the

Federal Resources Help Protect People and Wildlife from Harmful Algal Blooms

Did pea-green lakes and rivers appear in your community in 2017? Hot and dry conditions across
many areas of the Unites States coincided with elevated nutrient levels in surface waters to cre-
ate harmful algal blooms (HABs) in waters from California to New Hampshire to Florida. To
inform state and local officials and provide them with the tools they need to protect the health of
people and wildlife living in their watersheds, the U.S. Environmental Protection Agency (EPA),
U.S. Geological Survey, National Oceanic and Atmospheric Administration (NOAA), and other
federal agencies offer numerous guidance manuals, news sources, and other resources related to
cyanobacteria and HABs. States and communities can access these materials to help protect public
health as they prepare for warmer days ahead in 2018. Many states also maintain their own HAB-
related web pages.

VJhat are HABs?

HABs are the result of an overgrowth of algal colonies that can have harmful or toxic effects
on people or aquatic life (Figure 1). Cyanobacteria, commonly referred to as blue-green algae,
are photosynthetic bacteria that occur naturally in surface waters, including those used for
primary contact recreation, such as swimming and waterskiing. Under certain conditions, such
as high water temperatures and nutrient levels, cyanobacteria can grow rapidly to form dense
accumulations known as cyanobacterial blooms. Some harmful cyanobacterial blooms, sometimes
called cyanoHABs, produce cyanotoxins (e.g., microcystins, cylindrospermopsin) that have
poisonous effects on humans and animals, affect drinking water sources and negatively impact
local economies.

The most common routes of exposure to cya-
nobacteria and their toxins during recreational
activities are:

•	By mouth, from accidental or deliberate
ingestion of contaminated water.

•	Via skin, by direct contact of exposed parts
of the body to water containing cyanobacte-
rial cells or by exposure of skin to the water
in bathing suits.

•	Through inhalation, when HAB toxins are
aerosolized (turned into tiny airborne drop-
lets or mist) and are breathed in.

For more information about HABs, including
partner resources, graphics/photos, videos,
webinars and blogs, see EPA's Harmful Algal
Blooms website. [Note: resources on exposure
to cyanotoxins through drinking water are
addressed on EPA's Cyanotoxins in Drinking
Water website.]

Locations of Harmful Algal Blooms (2008-2017)

HAB problems persist across the country, posing risks to humans, livestock, pets and wildlife that
contact the water (Figure 2). In June 2017, the Minot Daily News reported that several livestock
died in northwest North Dakota after drinking pond water experiencing blue-green algae blooms.
In July 2017 the Capital Press reported that 32 head of livestock in Lake County, Oregon, died
after drinking from a reservoir that was experiencing a cyanobacteria bloom. Also in July 2017, the
Sacramento Bee reported that two dogs died after swimming in a Napa County pond that con-
tained toxic blue-green algae.

EPA tracks postings of HAB-related advisories
including blooms, cautions, warnings, public health
advisories, and public health warnings due to the
presence of algae, toxins, or both. The number of
HAB-related events, including advisories issued
each year across the United States typically begins
increasing in the spring, peaks in late summer, and
declines by mid-autumn. For example, in 2016
more than 475 HAB-related events were publicly
reported, with a high of 133 cases reported in July
2016. In 2017 that number increased to a total of
822 HAB-related events, with a September 2017
peak of 225. During the hot summer months, the
prolonged warming of surface waters favors the
growth of HABs, therefore a higher occurrence of
blooms will be reported during the warmer months
than colder months. This is especially of concern as
"the number of HAB events appear to be increasing
each year in frequency in the United States, which
could be attributed to the combination of excess of
nutrients, warmer temperatures and an increase in
sampling and monitoring," explains EPA's Lesley
DAnglada.

Communicating the Dangers of HABs to the Public is Key

To support water managers who are facing challenges with HABs in their jurisdictions, EPA offers
numerous resources to help with planning, education and implementation. EPA's Cyanobacterial
Harmful Algal Blooms in Water website offers detailed background information and resource links
describing cyanobacteria and cyanotoxins in marine waters and freshwaters, their effect on health
of humans and wildlife, how to detect their presence, and how to control them. It also provides
state-based resources and links to numerous guidelines and recommendations for monitoring and
communication.

History of the Harmful Algal Bloom and Hypoxia Research and Control Act

In 1998, Congress recognized the severity of threats posed by HABs and hypoxic events and authorized
the Harmful Algal Bloom and Hypoxia Research and Control Act (HABHRCA 1998; embedded in Public
Law 105-383). The Harmful Algal Bloom and Hypoxia Research and Control Amendments Act of 2004
(HABHRCA 2004, Public Law 108-456) and 2014 (HABHRCA 2014, Public Law 113-124) reaffirmed
and expanded the mandate for NOAA and EPA to advance the scientific understanding and ability to
detect, monitor, assess, and predict HAB and hypoxic events in marine and freshwaters. NOAA and
EPA co-chair the interagency Working Group on HABHRCA (IWG), which coordinates with other federai
agencies to discuss HAB and hypoxic events in the United States, and to develop action plans. The IWG
develop action plans and assessments including the Harmful Algal Blooms and Hypoxia Comprehensive
Research Plan and Action Strategy: An Interagency Report, the Great Lakes HAB and Hypoxia Plan, and
the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force 2015 Report to Congress.

Purpose of the Toolbox

Recreational water managers should explore multiple ways to inform people using
recreational waters, as well as pet and livestock owners, of the health risks associated with
cyanobacteria and theirtoxins. Communication to the public may occurthrough signage at
the recreational water body, radio and TV announcements, and social media. Messages
should clearly define the different levels of risk and contamination, for example, the
exposure potential for specific recreational activities.

This toolbox provides resources for communicating risk to the public about cyanotoxins in
lakes, rivers or other recreational water bodies. Recreational water managers should also be
aware that toxins may be transported and affect downstream waters.

Notes From the States, Tribes and Localities

Kentucky Stockyard Limits Stormwater Runoff and Promotes Water Reuse

From disaster sometimes comes opportunity. When the 100-year-old Blue Grass Stockyards along
the banks of the impaired Town Branch Creek in Lexington, Kentucky, caught fire and burned to
the ground in January 2016, it jeopardized the jobs of dozens of people as well as the regional live-

	stock market for thousands of farmers. The massive three-alarm blaze at

the seven-acre collection of wooden sheds, barns, and offices spread and
also destroyed four neighboring businesses. The fire eventually involved
120 firefighters, prompted air quality warnings, and required the open-
ing of a Red Cross shelter at a nearby school. The stockyard, one of the
largest livestock facilities in the eastern United States, was destroyed.

Original Stockyard Faced Water Quality Challenges

The original Blue Grass Stockyards was built within the city limits of
Lexington near the banks of Town Branch Creek, several reaches of
which were listed as impaired for failing to support aquatic habitat
and recreational use because of urban stormwater runoff, the loss of
riparian habitat, and other causes. Over the years, the stockyard had
shown its commitment to water quality protection by implementing a
number of grading, berming, vegetative and structural improvements
that helped to address concerns regarding runoff" from the stockyards.
However, the large number of animals moving through the facility,
the cramped location, and the proximity to the creek made the site a
perennial priority in terms of water quality protection. After the fire,
owners of the stockyard knew they had an unprecedented opportunity
to do something different. It was time to start anew—bigger, better
and cleaner.

Figure 1. Steve Higgins explains water quality best
management practices to attendees at the Scott
and Fayette County Farm-City Field day, held in
late August 2017 at the new Biue Grass Regional
Marketplace stockyard facility.

Figure 2. New stormwater ponds are equipped with
drive-in ramps to allow removal of accumulated
sediment.

Figure 3. Livestock loading areas are largely under
roof to avoid introducing manure and bedding into
the stormwater discharge.

"The stockyard owners wanted to build a state-of-the-art facility that
showcased the best of the best management practices," said Steve
Higgins, Director of Animal and Environmental Compliance at the
University of Kentucky College of Agriculture. "We put our collective
heads together to design something that everyone could be proud of."

New Stockyard Incorporates Water Quality Best Management
Practices

The new Blue Grass Regional Marketplace facility, which opened in
September 2017 at a new location about six miles north of the old site,
features an 86,600-square-foot roofed stockade and sales pavilion, with
an adjacent 40,000-square-foot restaurant and office building. The site
includes numerous water quality best management practices that are
drawing attention (Figure 1). The new site drains into Cane Run, a
tributary of North Elkhorn Creek. To protect water quality, the facil-
ity's design includes two stormwater detention ponds with sand filter
outlets that collect drainage from access roads and parking lots. Both
ponds feature concrete sedimentation forebays constructed as long,
rectangular open-topped boxes with drive-in ramps to accommodate
front-end loaders and skidders dispatched to remove accumulated solids
(Figure 2). These settling basins and their flow controls provide a deten-
tion time of 40 minutes for a two-inch storm event. Discharges from
the settling basins are then routed to detention ponds that can accom-
modate 100-year storm events.

"The new stockyard is located in the Cane Run Watershed but not in
the recharge area for the aquifer that supplies Royal Springs, which
provides part of the drinking water for the city of Georgetown,"
Higgins said. "Regardless, we wanted to make sure the design and
operational plans met the strict requirements of Georgetown's source
water protection plan. It took a lot of discussion with state and local
water quality officials to get to a place where everyone is comfortable.
I think we're there, now."

The entire operation is under one roof, which allows the facility to minimize polluted stormwater
leaving the site. Cattle are moved quickly from farm trucks and trailers to the covered stockade
and sales areas, and then to other vehicles for transport (Figure 3). Manure and bedding are stored
under the same roofed area, and a third party vendor removes the used bedding and manure and
transports it to an offsite composting operation. Rainfall and snowmelt from the facility's roof is
collected and routed via underground pipes to a separate "clean water" pond that holds 1.5 mil-
lion gallons at the normal pool and 3-4 million gallons at the spillway
elevation (Figure 4). This pond supplies the water needs of livestock in
the stockade area.

Figure 4. Clean runoff water from the facility's large
rooftop is routed to a water storage pond and is used
to provide water to the livestock at the facility.

Software Spotlight

National Stormwater Calculator Expands and Goes Mobile

The U.S. Environmental Protection Agency's (EPA's) National Stormwater Calculator (NSWC)
software application is now better than ever. It was recently expanded to include a cost module
and climate scenarios, and is now available as a mobile web application so you can take it with you
into the field. Using national databases and user-entered data, the NSWC can be used to estimate
the annual amount of rainwater and the frequency of runoff from a specific site, with and without
low impact development (LID)/
green stormwater infrastructure
practices in place. It is designed
to be used by anyone interested in
reducing runoff from a property,
including site developers, land-
scape architects, urban planners
and homeowners.

How Does the NSWC Work?

The NSWC can be used to
estimate the amount of storm-
water runoff that a site generates
under different stormwater control
scenarios. The calculator accesses
several national databases that
provide soil, topography, rainfall
and evaporation information for
the chosen site.

The user supplies land cover information indicating the type of development they wish to ana-
lyze, then selects a mix of LID controls that could be used on the site, such as impervious area

disconnection, rainwater harvesting, rain gardens, green roofs, street planters, infiltration basins,
porous pavement.

Using these data, the NSWC assesses how well different types of LID practices can capture and
retain rainfall on-site, and also estimates capital and maintenance costs to help planners evaluate
which choices are best for their site. The SWC can answer questions such as:

•	What is the largest daily rainfall amount that can be captured by a site in either its predevel-
opment, current or post-development condition?

•	How well can storms of different magnitudes be captured on site?

•	What mix of LID controls can be used to meet a given stormwater retention target?

•	How well will LID controls perform under future meteorological projections?

•	What are the relative cost (capital and maintenance) differences for various mixes of LID
controls?

The NSWC uses the EPA Storm Water Management Model (SWMM) as its computational
engine. SWMM is a well-established, EPA-developed model that has seen continuous use and
periodic updates for 40 years. Its hydrology component uses physically meaningful parameters,
making it especially well-suited for application on a nationwide scale. SWMM is set up and runs
in the background without requiring any involvement of the user.

The calculator is most appropriate for performing screening-level analyses of small-footprint sites
(up to several dozen acres in size) with uniform soil conditions. More information about the
NSWC is available in a September 2017 National Stormwater Calculator Fact Sheet and a free,
archived webinar held in January 2018.

Federal Agencies Partner on Animal Agriculture Education Project

The U.S. Environmental Protection Agency (EPA) is partnering with the U.S. Department of
Agriculture (USDA) Natural Resources Conservation Service on the Animal Agriculture Education
Project, a series of educational modules designed to increase understanding and knowledge among
state and federal government agencies and the agricultural industry about water quality protection,
manure management, and animal feeding operations. The project will include multimedia features
such as videos and virtual tours of farms, and will discuss topics including advances in technolo-
gies and production systems, measures to protect water quality, and issues such as on-farm decision
making about manure management. An overview module for this project, Animal Agriculture,
Manure Management, and Water Quality, was released in early 2017. This module was developed
with funding from EPA and with input from animal agriculture stakeholders. It addresses trends
in animal agriculture, manure collection and storage, land application of manure nutrients, water
quality issues associated with manure, Clean Water Act requirements and planning for stewardship.

Australian Student's Stormwater Mapping Toolbox Used Worldwide

A stormwater mapping tool created by Alan Pearse, a 19-year-old Australian student, is allowing
hydrologists around the world to better map the movement of water and pollutants across different
landscape features. His tool, IDW-Plus (Inverse Distance Weighted Percent Land Use for Streams)
is used with the Esri open-source mapping platform ArcGIS. The purpose of IDW-Plus is to help
Esri ArcGIS users calculate six spatially explicit land use metrics for watersheds: (1) inverse flow
length to outlet (iFLO), (2) inverse flow length to stream (iFLS), (3) inverse Euclidean distance to
outlet (iEDO), (4) inverse Euclidean distance to stream (iEDS), (5) hydrologically active inverse
flow length to outlet (HAiFLO), and (6) hydrologically active inverse flow length to stream
(HAiFLS). The toolkit has already gained attention in the United States: U.S. Geological Survey
(USGS) hydrologists are using it to study how natural hazards threaten water resources and the
USDA is offering IDW-Plus on its Rocky Mountain Research Station's Spatial Modeling website
for scientists to download and use. To acknowledge his exceptional work and accomplishment, Esri
Australia awarded Mr. Pearse, a third-year student at the Queensland University of Technology,
the Australian Esri Young Scholars Award.

Combining Water Assessment Data from Multiple Sources

A recent USGS study, "Challenges with secondary use of multi-source water-quality data in the
United States," reports that almost 60 percent of previously collected nutrient water quality records
for U.S. rivers and streams have missing or ambiguous reference information. This inconsistency
limits the use of these data for assessing water quality across large river basins. The study found
that nearly 14.5 million of the 25 million records collected since 1899 by nearly 500 public and
private organizations at 321,927 sites across the country had missing or ambiguous metadata,
which is the standard descriptive information needed to determine the amount of a chemical pres-
ent in the sample. By adopting standard metadata practices across all monitoring organizations in
the United States, the quality and amount of data that could be used to assess water management
actions could be significantly increased. The National Water Quality Monitoring Council—a
group of federal, tribal, interstate, state, local and municipal governments; watershed groups; and
national associations that include volunteer monitoring groups—is developing sets of water quality
data elements that could facilitate the exchange of water quality data among multiple agencies.

Phone App Offers Access to National Low Impact Development (LID) Atlas

The NEMO [Nonpoint Education for Municipal Officials] program at the University of
Connecticut has developed a new mobile-friendly version of the National LID Atlas. Available for
any mobile device (iOS, Android, Windows Phone, etc.), you can explore the practices near you
or start adding your own. The Atlas is a national database of examples of LID/ green stormwater
infrastructure developed by the National NEMO Network. The new version offers these features:

•	LID Near You. When you load the mobile website it will zoom to your location and display
any examples of LID from the Atlas within a 10-mile radius.

•	Advanced Filtering. By clicking the filter icon, you can narrow down the types of sites that
appear by choosing a type of practice, state, city, land use type, or keyword. You can also set
how big of a radius around your current location you would like to search.

•	Calculating Impact. When you add a new site to the Atlas, you can enter the size of the
practice as well as the size of the drainage area being treated (drainage area). The app uses
local annual rainfall amounts to calculate the number of gallons of stormwater removed by
the practice per year.

High School Envirothons Offer Unique Educational Opportunities

Teams from Pennsylvania, New York and New Mexico high schools took the top honors at the
2017 National Conservation Foundation's Envirothon, held in Emmitsburg, Maryland in July
2017. Envirothon teams are tested on their knowledge in five topic areas: soils and land use, aquatic
ecology, forestry, wildlife and a current environmental issue that changes each year. Through the
program, students develop an understanding of effective teamwork, resource management and
ecology. At the same time, they gain valuable exposure to a range of disciplines while exploring
possible career paths in the environmental field. Now entering its 30th year, the Envirothon program
continues to grow, reaching more than 500,000 young people across the United States and beyond.
More detailed information is available online, including contacts for local Envirothon teams,
downloadable brochures, and videos and photos from past events. The 2018 Envirothon will be

Tool Facilitates Engaging Forest Landowners and Fostering Stewardship

The Sustaining Family Forests Initiative—a collaborative initiative between the Yale School
of Forestry & Environmental Studies, the U.S. Forest Service, and the Center for Nonprofit
Strategies—has launched a new tool aimed at gaining and disseminating comprehensive knowl-
edge about family forest owners throughout the United States. Tools for Engaging Landowners
Effectively (TELE) helps natural resource professionals from all sectors design more effective
outreach programs. Tips and techniques included in TELE demonstrate how to connect and share
targeted information with specific woodland owner types: (1) woodland retreat owners, who place
higher importance on lifestyle and amenity reasons for owning woods; (2) working the land owners,
who assign high importance to both lifestyle and financial reasons for owning woods; (3) supple-
mental income owners, who are the opposite of woodland retreat owners, assign high importance to
financial reasons for owning woodland, but lower ratings on amenity reasons; and (4) uninvolved
owners, who assign relatively low importance ratings to all the reasons for owning woods. TELE
helps promote stewardship practices among landowners, such as building trails, protecting water
quality, or anything in between. The approach includes a simple six-step process that helps users
leverage resources to successfully reach a larger, more diverse set of landowners.

green infrastructure designs. These projects show how managing stormwater at its source can ben-
efit the community and environment by reducing the burden on local water infrastructure, manag-
ing local flooding, reducing urban heat islands and lowering energy demands. The 2016 competi-

involvement with the local community, city, state or other organizations could help support the
proposed project. EPA invited student teams to compete in two design categories: the Master Plan
category, which examines how green infrastructure can be integrated into a broad area of a school's
campus, and the Demonstration Project category, which focuses on how green infrastructure can
be integrated into a particular site on the team's campus. Teams of undergraduate and graduate
students, working with a faculty advisor and in many cases campus facility managers, developed
innovative green infrastructure designs in one or both of the categories to show how managing
stormwater at its source can benefit the campus community and the environment. For more infor-
mation, visit the 2016 Campus RainWorks Challenge website or read the 2016 Campus RainWorks

Green Infrastructure Effectiveness Database Compiles Resource Information

The National Oceanic and Atmospheric Administration's (NOAA's) Office of Coastal
Management assembled a collection of information from a wide array of literature sources
(e.g., peer-reviewed journals, online tools, government reports, issue papers, conference proceed-
ings) that document how well green infrastructure techniques reduce the impacts of coastal
hazards. This information is presented in an online Green Infrastructure Effectiveness Database,
which allows users to quickly search for basic source information, key findings, identification of
characteristics that influence effectiveness, and a link to the original source, if available. The data-
base is not an all-inclusive source of NOAA's literature related to green infrastructure, but rather is
a collection of literature sources reporting techniques for improving resilience to coastal hazards.
Currently, the database contains information on 32 different coastal green infrastructure practices
and techniques that cover a full range of approaches to coastal management. The database also illu-
minates gaps in information and areas that should be studied further. NOAA intends to continue
adding to the database over time.

Green Infrastructure Training Tools Offered

NOAA has developed multiple training products to guide communities through the green
infrastructure planning process. The products are offered through NOAA's Digital Coast, a
website that serves as a central repository for data, tools, training and information pertinent
for communities engaged in coastal resource management. One of the instructor-led courses,
Introducing Green Infrastructure for Coastal Resilience, covers fundamental concepts and
practices that can be integrated into local planning processes. NOAA's Office for Coastal
Management will bring this training to your doorstep while providing the instructors and all the
materials at the request of your agency or organization. The cost is minimal for participants and
the host. Through its Digital Coast Training website, NOAA also offers other online instructor-led
courses and information on how to protect and manage coastal resources.

Report Explores Private Financing for Green Infrastructure

A recently released report, Public Private Partnerships and Finance of Large-Scale Green
Infrastructure in the Great Lakes Basin, presents the initial findings of an initiative to expand the
use of green infrastructure in the Great Lakes Basin through the use of private financing and/
or contracted services. The Great Lakes Basin includes parts of the states of Illinois, Indiana,
Michigan, Minnesota, New York, Ohio, Pennsylvania and Wisconsin. The report assesses the
market size for large-scale adoption (i.e., investment of at least $50 million) of integrated green
infrastructure practices, with an emphasis on communities that could best benefit from using
green infrastructure to address their stormwater management challenges. Supported by the Great
Lakes Protection Fund, the report covers a number of tools that can be used to aid communities
considering establishing a public-private partnership (P3). The tools include a newly developed
decision tree for use as a preliminary filter to assess the viability of a P3 in a specific community.
The decision tree is applicable for communities that have either municipal separate storm sewer
systems or combined sewer overflows.

Report Highlights Economic Markets and Green Stormwater Infrastructure

Hie Willamette Partnership recently released a report summarizing how stormwater managers can
work with market forces to address critical stormwater issues. The report, Working with the Market:
Economic Instruments to Support Investment in Green Stormwater Infrastructure, illustrates how
communities can use economic instruments (e.g., rebates, subsides, trading, mitigation) to create
action or drive investment that helps communities meet their environmental goals. This report
was authored by Willamette Partnership and Storm and Stream Solutions, and supported by the
National Network on Water Quality Trading.

Report Recommends Actions to Integrate Green Infrastructure in NYC

In response to a request by the New York Department of Environmental Protection (DEP), the
Natural Resources Defense Council partnered with the New York University Stern School of
Business' Center for Sustainable Business to examine how New York City could successfully
develop and launch a large-scale grant program that would spur green infrastructure construc-
tion on private property. The partners published their findings in an August 2017 report,
Catalyzing Green Infrastructure on Private Property: Recommendations for a Green, Equitable, and
Sustainable New York City. After reviewing initiatives occurring around the country, the authors
concluded that DEP should commit to and communicate with the public to help make green
infrastructure on private property a core component of New York City's sustainability efforts. The
report also contained the recommendation that the DEP partner with community-based organiza-
tions to help the new program successfully achieve plan OneNYC goals. The authors noted that
DEP should create a new grant program that provides a direct financial benefit, such as compensa-
tion for long-term green infrastructure maintenance and on-bill loan financing, to private property
owners who invest in green infrastructure. Finally, the authors recommended that DEP institute
new rules for new development and redevelopment projects to manage stormwater on site, thereby
reducing the volume of runoff, and that DEP adopt a new fee structure on water and sewer bills to
more equitably apportion stormwater management costs across the city.

Harmful Algal Blooms

Automated Bibliography Features Agriculture-Linked Algal Bloom Research

The National Agricultural Library has created Great Lakes Harmful Algal Blooms and Hypoxia:
Agricultural Aspects, an online, automatically updated bibliography listing current research on the
links between agricultural operations and harmful algal blooms and hypoxia affecting the Great
Lakes. The bibliography is generated using an automated search of the Scopus database, the largest
abstract and citation database of peer-reviewed literature including scientific journals, books and
conference proceedings.

Online Training Introduces Remote Sensing of Harmful Algal Blooms

The National Aeronautics and Space Administration's (NASA's) Applied Remote Sensing Training
program offered an online training in September 2017, Introduction to Remote Sensing of
Harmful Algal Blooms. The training, now available for free as a self-directed online course, was
designed to: (1) help people identify NASA's Earth Science remote sensing data products that can
be used to identify and monitor HABs, (2) understand how coupled remote sensing and modeling
approaches are used in decision support tools, and (3) use a selection of NASA Earth Science data
tools to monitor HABs. These skills can help decision makers know where to collect water samples,
determine what toxins are in the water, whether they need to change or move drinking water
intakes, and whether a fishery needs to be closed. Accessing remote sensing data enables individu-
als and organizations to create more flexible plans for water sampling, and leads to a more efficient
and appropriate allocation of resources for protecting human health.

Paper Describes Use of Algal Indicators to Diagnose Nutrient Pollution

In June 2017 EPA published a summary paper, Algal Indicators in Streams: A Review of their
Application in Water Quality Management of Nutrient Pollution, which describes the use of algal
indicators to develop water quality diagnostics for nutrient pollution in the United States and
reviews scientific developments in the application of algal indicators across the world. The informa-
tion will help water quality managers better understand when and how to use algae as indicators of
nutrient pollution in stream ecosystems.

Researchers Use Genes as Early Warning System for Harmful Algae Blooms

In one of the most comprehensive studies to date, researchers at the University of North Carolina
at Chapel Hill have sequenced the genes of a harmful algal bloom, unveiling never-before-seen
interactions between algae and bacteria that are thought to propagate their growth. The work also
opens up the possibility of forecasting the appearance of a bloom and taking measures to prevent it.

Team Creates Warning System for Toxic Algae in Lakes

Scientists at EPA are part of a team of specialists using remote sensing data to improve cyanobacteria
detection methods. EPA is working with partners on the Cyanobacteria Assessment Network
(CyAN) to use historic and current satellite data to monitor algal blooms and develop an early
warning system for toxic and nuisance blooms that could harm public health. Since the project
began in October 2015, CyAN imagery has been used to successfully detect algal blooms before
traditional monitoring efforts alerted watershed managers in Ohio, Florida, California, Vermont,
New Hampshire, Massachusetts, Connecticut and Rhode Island. The goal of this project is to
provide access, through an Android mobile application and other interactive resources, to satellite
images and data that show the concentration and extent of chlorophyll-^ and cyanobacteria in
the continental United States. In November 2017 EPA hosted a Monitoring Cyanobacteria with
Satellites webinar that highlighted ongoing work.

Hydromodification

Map Marks U.S. Dams Removed During the Past Century

Researchers have found that the benefits of dam removals far outweigh the alternative of leaving
dams in place. Many dams that once supported local economies have aged, no longer serve their
intended purposes, or have become unsafe. Dams have been found to disrupt several character-
istics of rivers including their natural flow, water temperatures, water quality, sediment transport
and biological function. The removal of dams has become an effective river restoration tool that
aids in the reversing of damage and restoring a river's integrity. American Rivers has developed an
online map showing the location of all U.S. dams removed from 1916 through 2016. Each marked
location includes information about the dam that was removed, including its physical characteris-
tics, name, age and location. River restoration practitioners, including federal and state agencies,
engineering design firms, other consultants and nonprofit organizations, have played a major role
in restoring the ecological integrity of rivers through the removal of dams.

Watershed Management

Municipalities to "Pay-For-Success" to Meet Clean Water Requirements

In June 2017 the Chesapeake Bay Foundation (CBF) announced it will receive an innovative
federal grant designed to put conservation practices on Pennsylvania farms that will allow
municipalities to satisfy stormwater pollution reduction requirements and return profits to capital
investors. The Conservation Innovation Grant of $415,000 from the USDA Natural Resources
Conservation Service is to be matched by CBF and multiple partners for the three-year project.
With the grant, CBF and partners will apply an innovative pay-for-success (PFS) approach. Under
the PFS approach, select municipalities contract to pay a financial intermediary. With capital from
private investors, the intermediary contracts with service providers to install pollution reduction

measures on farms. If the desired pollution reductions are achieved, the municipality can apply the
results to satisfy its urban/suburban stormwater compliance requirements. The municipality will
then pay the intermediary, which in turn repays investors, with interest.

Report Shows Trading Programs Not Widely Used

The General Accounting Office (GAO) was tasked with examining nutrient credit trading
programs. In October 2017 the GAO released its results in a report, Some States Have Trading
Programs to Help Address Nutrient Pollution, But Use Has Been Limited, that describes: (1) the
extent to which nutrient credit trading programs have been used and what the outcomes of the
programs have been, (2) how states and EPA oversee nutrient credit trading programs, and (3) what
key factors stakeholders view as affecting participation in nutrient credit trading. GAO selected
a sample of three state programs with the most trades in 2014; reviewed program documents;
and interviewed EPA, state, and program officials and other stakeholders about the programs.
According to stakeholders, two key factors have affected participation in nutrient credit trading:
the presence of discharge limits for nutrients and the challenges of measuring the results of nutri-
ent reduction activities from nonpoint source projects. Officials from the three state programs
and other stakeholders cited the importance of discharge limits for nutrients as a driver to create
demand for trading. Without such a driver, point sources have little incentive to purchase nutrient
credits. The challenges of measuring nutrient reductions from nonpoint sources create uncertainties
about the value of credits generated by nonpoint sources. In part, because of these uncertainties,
the states GAO reviewed either did not allow nonpoint sources to trade or created special rules
for nonpoint sources. State officials and stakeholders also told GAO that even if a program allows
nonpoint sources to trade, point sources often prefer to trade with other point sources because they
have similar permit and monitoring requirements.

Watershed Approach Mitigates Stormwater Impacts from Roadways

The Transportation Research Board's (TRB's) National Cooperative Highway Research Program
Research Report 840: A Watershed Approach to Mitigating Stormwater Impacts provides a practi-
cal decision-making framework that will enable state and local departments of transportation to
identify and implement off-site cost-effective and environmentally beneficial water quality solutions
for stormwater impacts when on-site treatment or mitigation is not possible within the right-of-
way. The multiyear research effort includes the development of the Watershed Based Stormwater
Mitigation Toolbox (WBSMT), a Microsoft Excel-based program that helps characterize the
project watershed and identify mitigation options at the planning level. The WBSMT uses readily
available national datasets and can be used to evaluate common stormwater pollutants of concern. It
can easily be adapted for evaluating targeted regional and local datasets and complex and emerging
watershed protection issues, such as ecosystem services. The research report and the WBSMT can
be found at TRB's website: A Watershed Approach to Mitigating Stormwater Impacts.

Winter Maintenance Assessment Tool Reduces Salt in Minnesota

Minnesota state agencies, local municipalities and experts within the Twin Cities Metropolitan
Area created a partnership to develop a chloride management plan to effectively minimize and
manage salt (primarily sodium chloride) use for deicing purposes in order to protect water
resources. As part of this plan, the Winter Maintenance Assessment tool (WMAt) was developed
as an all-encompassing resource listing approximately 180 salt-reducing best management prac-
tices. The web-based tool was developed to help public and private winter maintenance profession-
als and organizations assess their current practices, determine which practices can be modified to
reduce the use of salt, track their progress over time, and display the results of their efforts. Users
of the tool will be asked questions about their winter maintenance activities on roads, parking lots
and sidewalks or other areas where road salt is used as a deicer. The tool then generates a report
that summarizes their current practices and identifies areas of improvement. It highlights specific
best management practices unique to each operation, as well as the timeframe that would be
required to incorporate those changes.

Water Monitoring

Data Show Pesticides Prevalent in Midwestern Streams

More than 180 pesticides and their byproducts were detected in small streams throughout 11
Midwestern states, some at concentrations likely to harm aquatic insects, according to a 2017
USGS study, Complex mixtures of dissolved pesticides show potential aquatic toxicity in a synoptic
study of Midwestern U.S. streams. On average, 52 pesticide compounds were detected in each
stream. At least one pesticide in at least half of the 100 streams sampled exceeded a threshold
predicted to cause harm to aquatic insects and other stream organisms. Pesticides were not mea-
sured at levels predicted to be toxic to fish in most streams. Although numerous pesticides were
detected at low levels, only a few—atrazine, acetochlor, metolachlor, imidacloprid, fipronil and
organophosphate insecticides—were predicted to be major contributors to toxicity. The first three
are widely used agricultural herbicides, and the latter three are insecticides used in both residential
and agricultural settings. This is one of the most extensive assessments of pesticides in streams to
date: 1,200 samples were collected at 100 Midwest streams over a 12-week period during the 2013
growing season and analyzed for 228 pesticide compounds. This study is one component in the
first in a series of five USGS regional stream quality assessments.

EPA Releases Route to Resilience Tool

Maintaining and repairing aging drinking water infrastructure remains a significant challenge
for the water sector. Utilities must be able to increase their readiness and resilience to potential
all-hazard incidents and adapt to future hazards that could impact their ability to provide safe and
clean drinking water. EPA is releasing the Route to Resilience (RtoR) tool that will help small- and
medium-sized drinking water and wastewater utilities learn more about becoming resilient to
hazards such as floods, tornadoes, hurricanes and contamination incidents. The interactive desktop
application guides utilities through five stops along the Route to Resilience: (1) Assess, (2) Plan,
(3) Train, (4) Respond, and (5) Recover. RtoR also provides utilities with a custom report that
highlights products and tools that will help guide utilities in their efforts to become more resilient.

Tools Provide Compliance Assistance for Construction Stormwater Program

As part of EPA's compliance assistance for the National Pollutant Discharge Elimination System
(NPDES) construction stormwater program, EPA created a "Do I Need A Permit?" flow chart to
help construction operators determine if and from whom they need to get NPDES permit cover-
age for their construction activities. EPA also updated the Stormwater Pollution Prevention Plan
(SWPPP) template and Inspection and Corrective Action Report templates for the new 2017
Construction General Permit (CGP). These fillable templates help construction site operators
develop a SWPPP and prepare inspection and corrective action reports that meet the requirements
of EPA's 2017 CGP. The templates are available on the Construction General Permit: Resources,
Tools, and Templates website.

Eutrophication Will Increase During the 21st Century as a Result of Precipitation Changes

This article, published in the Science July 28, 2017, issue (Vol. 357, Issue 6349, pp. 405—408), high-
lights evidence from a recent study that discusses how changing precipitation patterns will substan-
tially increase riverine total nitrogen loading within the continental United States by the end of the
century. These impacts are driven by projected increases in both total and extreme precipitation,
and will be especially strong for the Northeast and the corn belt of the Midwest. Offsetting the
anticipated increases would require a significant reduction in nitrogen inputs from runoff, direct
discharges and air deposition.

Harmful Algal Bloom-Associated Illnesses in Humans and Dogs Identified Through a Pilot
Surveillance System — New York, 2015

This article, featured in the Centers for Disease Control and Prevention's Morbidity and Mortality
Weekly Report on November 3, 2017, features results from a pilot harmful algal bloom (HAB) sur-
veillance system conducted by the New York State Department of Health (NYSDOH). The system
was implemented in 16 New York counties in order to assess the extent to which nutrient-fueled
HABs in state waters affects humans and dogs. Activities included collecting data from environ-
mental HAB reports, illness reports and poison control centers, and conducting outreach to the
public, health care providers and veterinarians. Before 2015, HAB-associated illness reports made
to NYSDOH never exceeded 10 statewide in any given year, whereas 51 illness reports were made
through the pilot surveillance system across the 16 participating counties during June—September
2015. Of the 51 reports identified through the pilot surveillance system, 35 were considered cases
of HAB-associated illness meeting the Centers for Disease Control and Prevention's case defini-
tion, suggesting that the occurrence of such illnesses might typically be underreported.

Hal Wise's Legacy Lives On

By Elaine Bloom, NYS Department of Environmental Conservation

Much has changed since Hal founded
Nonpoint Source News-Notes and in the
decades since we lost him. But, as his
colleague and friend, I know he'd be
gratified that News-Notes continued
to connect, inspire and inform the
community that formed around it. He
was adored by these front-line folks,
and it was mutual. They were his energy
source, his fountain of youth, his
inspiration. He delighted in sharing their
