Development of TMDLs requires quantification of flow duration and load duration data
for the waterbody

of concern. Flow and load duration curves help identify specific flow regimes
for which water quality standards are violated. Similarly, load reduction strategies for point and
nonpoint source pollutants to meet TMDLs are usually identified using the fl
ow and load
duration curves. Traditionally, development of these curves have been a time consuming process
involving downloading and processing of flow and water quality data, and plotting of the data in
a format suggested by EPA. We have developed an on
line tool to automate this process

(see
https://engineering.purdue.edu/~ldc
)
. The on
-
line tool provides options to upload flow and water
quality data. Alternatively, a user can select stream flow data fr
om an existing USGS gauging
station using a Google Map
s

interfac
e for the tool. The Google Maps

interface has allowed us to
scale the applicability of this tool to any watershed within the continental US. We have provided
training for the use of this too
l to various stakeholder groups involved in TMDL development.
The use of this tool has resulted in significant time savings for the groups involved in TMDL
development. In addition, it has provides a consistent approach of quantifying and interpreting
fl
ow and load duration curves
within

watershed
s
.


This proposal includes two aspects
. T
he first
will upgrade a web
-
based tool for
calculating load duration curves
(often used in TMDLs)
into one that will have more utility and
improved decision
-
making capabil
ity because it connects to the exchange network web services
.

The

second aspect will facilitate uploading
six

pesticide registration data (FIFRA) sets into the
EPA exchange network (CDX) which are not now
available

there
.

This project will directly
support

the mission of the Exchange N
etwork

(EN)

as

it will improve environmental data access
and improve environmental analysis for a large number of users who do

not currently have that
access. T
he improvements will streamline a regulatory process and lower
the
burden
and costs
currently part of the TMDL process
.


The project clearly addresses goals from the EPA FY 2011 to 2015 Strategic Plan. EPA
Goals
2, 3,4 and 5

are all addressed through a project that uses exchange network data to
improve and streamline

TMDL

process as well as
to improve and streamline a
process used in
designing and monitoring of
best management practices (
BMPs
)

for water quality.


Th
is

proposal
fits into the Exchange N
etwork strategic plan as well as the EPA strategic
plan by meeting s
pecific exchange network strategic goals
, specifically under objective 2,
expanding the exchange network use to support more environmental decision
-
making. Under the
performance metrics for thi
s objective
,
this project would be counted under 4.2.2.1 and 4.
2.4
.

This project also presents a supplemental
data
flow opportunity, which is a performance metric
for subobjective 2.2 of the strategic plan.


The
online
load duration curve tool has been used in the creation of TMDLs in Indiana,
and this use has provid
ed feedback from

the user community and the
agency
responsible for

TMDLs in Indiana
, the
Indiana Department of
E
nvironmental
M
anagement
. This
proposed
upgrade and extension will provide improvements

to the tool that result from the user community
feedback,

and also will incorporate a connection to the STORET Results Web Service

to provide appropriate water quality information to the tool
during use. This will

.


The second phase of this project will

Narrative


Aspect 1: Improvements for Online Load Duration Curve Tool



Load duration curves are used in water quality work to evaluate and design best
management practices (BMPs) and are
often
used in the process to develop a TMDL. EPA
publication EP
A 841
-
B
-
07
-
006 states “… major advantage of the duration curve framework in
TMDL development is the ability to provide meaningful connections between allocations and
implementation efforts. Because the flow duration interval serves as a general indicator o
f
hydrologic condition (i.e., wet versus dry and to what degree), allocations and reduction targets
can be linked to source areas, delivery mechanisms, and the appropriate set of management
practices. (
An Approach for Using Load Duration curves in the Deve
lopment of TMDLs
, PG.17)


The use of zones within the d
uration curve such as high flow and

low flow
conditions
allows for the development of allocation tables which can be used to target implementation
actions to
obtain

the most response for the least cost.

The typical duration curve constructed
either by hand or with an online model requires location of f
low data typically from the US
Geological Survey

and accompanying water quality data for the same timeframe. The curve is
constructed showing flow changing over time
,

superimposing measured water quality points to
see where in the flow regime they were measured. The process to locate the water quality d
ata
currently is manual, labor
-
intensive, and time
-
consuming. This project will replace that effort by
connecting a web
-
based load duration curve tool to the STORET Results Web service. This
represents a significant reduction in labor and time required to

create and analyze a flow duration
curve, and will be use
able

by watershed managers, consultants, and environmental management
entities.


T
here are specific data requirements

for using the load duration curve tool
. The user first
locates USGS flow data an
d then locates water quality samples which were collected during the
period that flow data exists. In other words
,

specific time periods of data are important as well as
specific analytes. In the TMDL process only certain analytes are addressed, and inform
ation on
other water quality testing parameters is not needed. The project will set up a geo
-
RSS feed
tailored to provide information from the WQX that is pertinent to the TMDL process as needed
by the load duration tool. Often the data they do discover th
is way is not appropriate to the
TMDL process or does not cover the appropriate time and the user wastes resources in the
search.

igure

, a sample flow duration curve is displayed
with

water qu
ality data as diamonds and
points. The hydrologic condition is marked by vertical lines and labels across the top of the
graph. The significant point is that some BMPs only affect certain flow conditions
,

and those
conditions that represent the greatest lo
ad represent the most profitable target for BMPs.


Aspect 2: FIFRA Data Sets


The second a
spect of this proposal is the preparation and upload of six data sets.
Indiana laws
(I.C 15
-
16
-
4, I.C 15
-
16
-
5) authorize OISC to administer registration, storage, use and application
of pesticides within the state. A major statute responsibility of the agency is to prevent impacts
to Indiana surface and ground water quality
and the environment during regulated activities. The
OISC water quality program systematically addresses potential impacts by identifying pesticides
of interest and pesticides of concern.

Pesticide active ingredients of concern in Indiana and other pes
ticide state lead agencies become
the focus of regulatory and voluntary management measures in order to mitigate potential water
quality impacts. Examples of key pesticide program management measures evaluation include:



BMP implementation strategies



Nonpoint source watershed monitoring strategies



Utilization of internal monitoring data and data from pesticide registrants or other sources



Coordination of pesticide management measures with other federal, state agency or
research institutions including m
onitoring data, data on assessments and program
performance


The s
ix d
ata sets that
will be uploaded have been selected because they would be useful in

improving compliance and environmental stewardship associated with pesticides are summarized
in Table 1

Data sharing restriction regarding sample collection names (homeowner) and address.

The US EPA Region 5 Environmental Scientist in the Pesticide Program Section (Bruce
Wilkinson) indicated that as part of the FIFRA Cooperative Agreement reporting requirements,
the EPA would like to determine the proper method for transferring ground and s
urface water
monitoring data collected by or utilized by each FIFRA state lead agency to Office of Pesticide
Programs (OPP) for use in the Pesticide Registration Review Process.


The OISC is the agency
responsible for FIFRA within Indiana. The data overv
iewed in Table 1 will be evaluated and
appropriate data made available via XML web services. Completion of this effort will provide a
method for the transfer of this data.


Transfer of the technology developed in this project will be accomplished in several ways. Two
workshops will be conducted for potential users of the new data placed on the Exchange
Network, and two workshops will be held for potential users of the decisi
on support tools. The
data and decision support tools will be web accessible so their availability will be advertised
within Indiana and nationally.



A
pplicant‘s commitment to re
-
use existing EN tools or share new tools with EN partners
:


The decision

support tools developed can be readily extended to other states. Previous decision support
tools developed by the investigators have been extended to include other states within US EPA Region
5 and even nationally in several instances. The investigators

will inform other state agencies with
similar missions about the availability of the decision support tools and the potential to extend these
tools for use within their states.


Project Goals

1.

Enhance

the Load Duration Tool to allow users to simultaneously

consume water quality
data from the WQX, a Geo
-
RSS data flow from the Office of the Indiana State Chemist,
water flow data from the USGS real
-
time stream flow gauge network
, and water quality
data from the USGS Water Data for the Nation site
.

This existin
g
decision support tool

currently allows only manual upload of water quality data.
Enhancements proposed have
been identified as priorities by stakeholders using the tool as well as
by
potential users.

The user communit
y includes watershed and client

staff

constructing TMDL's
, watershed
groups, and environment and natural resource protection professionals
.

The

following enhancements will be completed.

1.1

D
isplay
on the
map
the
locations of available
and appropriate
water quality data.
The
LDC
user
interface
is based on Google M
aps, and centers around the user
selecting a USGS stream flow gauge. Currently the user then discovers water
quality sampling data that is nearby through any means they know,
search out
appropriate analytes, t
hen
they
manually reformat
available data into an explicitly
formatted text file,
and manually upload

to the web tool for calculations. The data
discovery process is supported by tools such as the Indiana water quality
monitoring inventory which is a web
-
based map of known sample lo
cations.
However
,

there is no automatic connection between known sample locations and
data sets. The addition of the ability to query

by clicking
a point on the map to
result in
a geo
-
RSS feed that can offer appropriate water quality data from the

AWQMS

database
and the USGS Water Data for the Nation site
formatted for the
tool
will be a huge benefit.

This step requires data discovery
of appropriate data
from the database
s

and parsing
of location data
in advance of creating a map
display.

1.2

Adapt the load
duration curve tool to use a geo
-
RSS feed as input. The project will
create a geo
-
RSS feed of the OISC data sets (see 2.4) after they are associated with
events on the NHD
, and other TMDL appropriate data which will be consumed
from the STORET Results web
service
. The
LDC
tool will be adapted to use these
as input. This public feed will be available both to the tool and also available to
other users who might be interested in consuming this data.

1.3

Implement in LDC an annual load module using LOADEST
calculations.

Add an
annual load module to the tool. The current tool performs calculations to create an
estimated load for a watershed, but does not create
all desired

outputs for the user
community. Minor improvements in the output features of this tool
would greatly
benefit teams constructing TMDL's and conducting other assessments where
pollutant load information is useful. The tool creates an estimate of distributions of
daily loads, which is useful and the basis for TMDL development. However, the
tool

currently does not produce an annual load, which is needed to actually
implement the TMDLs and other watershed plans at the watershed level. The USGS
LOADEST tool for computing annual loads will be incorporated into the tool. The
ability to compute annua
l loads would provide

the user community (including
Indiana Department of Environmental Management (IDEM) Assessment and
Watershed Planning Branch staff, watershed managers, consulting engineers, and
pesticide researchers) a much stronger tool.

1.4

Implement i
n LDC a standardized output report page.

User feedback has
determined that
output page standardization

for use in the
TMDL
process would be
of great benefit to many in the user community.

1.5

Implement in LDC an option to display and r
eport the reduction requi
red to reach
an annual goal

for a load reduction.

User feedback has determined that the ability to
input goals for load reduction as they are developed would significantly
simplify
the process of TMDL

development by replacing a large amount of manual
calcu
lation sometimes beyond the abilities of the watershed managers.

Empower WQ

1.6

Implement in LDC an option to use EPA STEPL approach reduction coefficients as
BMP targets.

Since the EPA STEPL approach is used in many states, the ability to
use it as an input to the onlin
e
tool

would greatly enhance the acceptance by
multiple states of the
enhanced

tool.

1.7

Implement in LDC the ability to evaluate the impact of BMPs by displaying
projected data on the load duration curve or target concentration graphics.

Another
upgrade reque
sted by user feedback from watershed managers and from state
environmental managers is a graphical display of a projected impact effect of a
BMP. For example a projected 10% reduction of phosphorus during moderate and
high flow conditions is difficult to t
ranslate into a load reduction because it only
occurs during some flow stages. Currently
,

a user must
manually
recalculate the
load at every stage of flow if one is changed, this could be automated in the
tool

easily, and would promote wider acceptance of
the
tool
.

1.8

Improved GIS locations and provide geospatial metadata for s
everal FIFRA data
sets held by the Office of the Indiana State Chemist
. These data

would be of use
by

teams constructing TMDLs. These
FIFRA
data are not
currently
available from
WQX nor
through other user
-
friendly methods. The data sets exist
now
within

spreadsheets. See
the
table below

for a list of these data
. The spreadsheet data must
be connected to the NHD water features.

This step requires
detailed analysis
within
a GIS system,
which includes
documenting the location data, reconciling the
location data to fit in a geo
-
RSS stream (
coordinate conversion to l
atitude
-
longitude
rather than meters).

1.9

Create events on the NHD data set to represent the improved locations. This step
will require
a detailed GIS process
that
will use

the recently released
HEM2XML
ArcMap tool

for ArcGIS to locate the sampling point
s

against the NHD layers and
create
an event for the sampling point

in an Extensible Markup Language (XML)
file that matches the Exchange Network
-
hosted NHDEvent schema format.

This
tool
[
http://www.epa.gov/waters/tools/HEM2XML/HEM2XML.html

]
was released
by EPA WATERS in
fall 2010.


The se
cond aspect of the project involves preparing and facilitating the upload of several data
sets which are not currently in the EN. These data sets would be of particular interest to a

team

constructing TMDLs if they were aware of these data. The steps below

will prepare the data for
upload into the EPA's CDX node using the node created at the Office of the Indiana State
Chemist through EPA funding in 2010. This particular node was established and credentialed in
2010 and is in the process of starting data fl
ows.

he O
ffice of the Indiana State C
hemist

(OISC)

has
pesticide sampling data sets used for label registration studies. These data are not currently in
the WQX AWQMS database. These data sets need

to be associated with NHD,
mapped to
the XML schema, implemented as a data flow, and also published as a geo
-
RSS Web service.

2.1

Map OISC FIFRA datasets to appropriate
WQX

schema. This would include a
detailed process to transfer the data into the XML schema
.

2.2

Map
the
locations of
the
different

FIFRA

data sets to appropriate
GIS features using
the
NHD event locations

built in 1.9
. This would include a detailed GIS process
which will

attach additional attributes to the data sets.
This process will involve

2.3

has

construct
ed

a node under separate funding which include
d

setting up,
credentialing,
configuration, and testing of the node.
T
he t
ask for
this project
will
be to implement

these specific data sets through that node.

2.4

-
RSS feed.
The project will set up a geo
-

o provide
information from the W
QX that is pertinent to the TMDL process as needed by the
load dur
ation tool.

2.5

Publish a WMS web service to allow other applications to do spatial query against
these data sets. This Web service will support spatial queries, in other words
querying by map location, either against the WMS service from a map click or by
pas
si
ng a latitude
-
longitude to the g
eo
-
RSS

stream (2.4) to provide appropriate
water quality data from the data set.

2.6

Create written documentation and t
rain state employees at OISC to process data sets
for EN flow.


2.7

Create web
-
based documentation for the new tool and train the user groups, which
includes state employees at Indiana Department of Environmental Management, in
the use of the improved web
-
based tool to integrate project outputs into the TMDL
program’s

busi
ness operations.


2.8

Establish a technical oversight committee to advise the principles on the broader
needs of consumers of pesticide data such as watershed managers, who are the
primary beneficiaries of this project.

2.9

Perform two workshops for users of the

p
esticide data sets.
