| The
topic selected for this year's roundtable was Siltation and Streamflow. These
two issues are of major concern for residents, landowners, and environmental agencies
across the state of Arkansas. Siltation is the leading contaminant of surface
water in Arkansas and the identifiable cause of many of the waterbodies to be
listed on ADEQ's newly revised 303(d) list. Many
state and federal agencies and conservation organizations are working on projects
to control and correct the various sources of sediment entering these waterbodies.
Several speakers joined in on this year's Roundtable Discussion to share their
projects, expertise, and goals for reducing sediment and siltation in Arkansas'
bayous, creeks, lakes, streams, and rivers. This
successful event attracted 37 participants from throughout the State. The topics
discussed led to an interactive question and answer session following the presentations.

ADEQ Water
Quality Standards: Addressing Siltation and Stream Flow Issues |
Martin
Maner, Chief Water Division Arkansas Department of Environmental Quality Many
of the streams on the 303(d) list are not meeting designated uses due to turbidity.
Sources of siltation include (1) highway construction, (2) improperly maintained
gravel roads, (3) runoff from construction sites, and (4) streambank erosion due
to riparian removal. Deposition of silt blocks streamflow causing lateral migration.
Regulators need local buy-in to make progress in stream water quality improvements/conservation.
Successful streambank stabilization projects must address bedload. Streambank
can be preserved by maintaining riparian vegetation, as stabilization projects
are very expensive. ADEQ is developing biological water quality criteria using
an index of biological integrity (IBI).

Streambank Erosion: ASWCC Projects | Ron

instability is caused by cattle traffic, gravel mining, and riparian removal.
The goal of restoration projects is to reconnect the stream to the old floodplain.
Planning, construction, setbacks, and progress were presented for several successful
restoration projects in NW Arkansas.

Streamflow and Suspended Sediment Concepts (with Examples from Arkansas) |
Reed
Green, Matt Moix, Jaysson Funkhouser, and Joel Galloway United States Geological
Survey USGS
maintains fifty-four monitoring stations that collect sediment data. Long-term
historical stream data is needed for planning. Stream width, depth, and velocity
is measured and recorded. Stream rating curves created and updated with these
measurements. Continuous flow data is needed for flood control, warning, and records.
Basin yield is defined as the amount of water produced within a watershed. Basin
yield is a function of slope, soil, and impervious area. Sediment in a stream
varies spatially and temporally. Sediment load is a function of drainage area,
rainfall amount and intensity, geomorphology, and land use. Sediment sampling
includes suspended sediment, bedload, and bed material. Samples can be analyzed
for total suspended sediment (TSS) or suspended sediment concentration (SSC).

Instream Flow Recommendations Using Proportional Analysis Methodology |

Layher Layher Biologics Stream
uses, such as fishing, recreation, irrigation, and assimilation, compete. Communities
must decide which uses the stream will support. The proportional analysis method
(PAM) studies stream habitat on the meso-scale. Fish populations in a segment
track the median environmental conditions of that segment. Median is more accurate
than mean because it is not skewed by a single isolated extreme event. |

Curbing
Development in Fourche Creek Watershed | Rob
Fisher and Daniel DeVun, both of Audubon Arkansas, presented information about
the Fourche Creek Watershed. Education and awareness are the main focus of the
Fourche Creek Project. The watershed consists of 109,000 acres in Pulaski and
Saline counties. The watershed drains to the Arkansas River. Rock Creek is a major
tributary. Rock Creek and Fourche Creek drains the Little Rock area and both creeks
have many restoration challenges. More public access is needed for Fourche Creek.
There are many concerns about Fourche Creek including: metals leaching from old
landfill, gravel mining, stream diversions, outdated dredging practices, ignoring
rules and regulations pertaining to construction, contaminants from impervious
surface, stream modification, increased flow regime, erosion, wetland destruction,
illegal landfills, and no stormwater retention in some sites. Flow regime problems
are increased by city mowing and maintenance crews.

Storm Water Requirements for Construction Activities |
|
Kim
Fuller, Arkansas Dept. of Environmental Quality, is the lead engineer for the
Stormwater Program. Permits have been required for construction sites of >
5 acres since 1992 when the NPDES stormwater program began. Phase II of the NPDES
program went into effect in March of 2003. Kim reported that Arkansas, along with
most other states, were behind in implementing Phase II. A general permit was
issued in September and went into effect on Nov. 1, 2003. A general permit is
not facility specific and includes all sites > 1 acre. Small site is 1-5
acres. A medium-large site is >10 acres in the flatlands and >20 acres in
highlands. A
Stormwater Pollution Prevention Plan should be submitted before breaking ground.
The Water Division will try to work with people to bring a project into compliance.
BMPs should be implemented to reduce runoff and site inspections performed and
controls documented. The permit is for disturbed acreage. An example would be
a 5 acre plot with a 2700 square foot house is not more than 1 acre of disturbed
land unless a large area was razed with a bulldozer. A question was asked about
how permits will be enforced. Kim Fuller commented that inspectors are present
in 13 districts, but they have other responsibilities other than enforcing permitting.
Most inspections are instigated by complaints from private citizens. Developers
will be contacted first if a violation occurs. Federal and State regulations state
that owner/operator is responsible. The EPA website has Federal regulations listed.
ADEQ links to EPA website. Small
sites have automatic permit coverage because there is a lack of manpower. No application
of Notice of Intent (NOI) is submitted to ADEQ, but must post NOI on site and
the Stormwater Pollution Prevention Plan should be kept on site. Medium and
large sites must submit application of NOI to ADEQ two weeks in advance. The cost
is $200.00. The Stormwater permit certificate must be posted on site along with
the Stormwater Pollution Prevention Plan. A Notice of Termination (NOT) should
be submitted to ADEQ when construction is complete. The Stormwater Pollution
Prevention Plan components include: One state
employee commented that state government has problems enforcing regulations but
city government has better success at enforcing city ordinances. Stop orders are
easier to enforce at city level than with ADEQ.
Fuller went on to comment that
ADEQ's regulatory authority ends after construction is complete. Fuller also stated
that anyone calling or sending a complaint should email pictures and directions
to site, if possible.
| Alternatives
to Impervious Surfaces | |
Martin
Smith, Landscape Architect, Larson, Burns and Smith, gave a design case study
showing the proposed Heifer International Office Building to be built in Little
Rock, Arkansas. The case study presented best management practices to reduce channelized
water and encourage sheet flow from parking area to landscaped areas where retention
ponds allow pollutants to filter out. Alternative paving materials for
the site includes crushed old building materials, allowing the materials to be
reused instead of being dumped in a landfill. Bioswales were introduced as a best
management practice to slow and filter pollutants from the stormwater as it leaves
the parking area. The retention ponds, or constructed wetlands, also allow pollutants
to drop out of the water column and decrease flooding during storm events. Smith
also stated that Heifer International will evaluate the effectiveness of the Stormwater
plan. Volume of water and water quality will be evaluated and evaluation procedures
will be used as educational tools for surrounding students. Lots of
discussion evolved from Smith's presentation and some comments are listed below: Stormwater
ordinances in Little Rock require retention time. Underground
retention would conserve landspace. It has been done in other cities but not here. Retention
ponds are not as safe as bioswale or underground retention. When costs decreased
they will be used more. Is
data available that proves water quality is improved? Yes,
research is available in the Northeast and Northwest. San Antonio has lots of
projects. Data on constructed wetlands is available. Some areas have become limited
on the amount of Phosphorus that can be removed from water. Retention/Detention
basin is best connected to bioswales to slow water. Fencing
should be provided for retention. Fencing keeps out trash and kids. When
retention areas are mowed, they are more attractive to kids. It
would be good to compare Heifer International, alternatives to treat stormwater
with a regular parking lot of comparable size. City
ordinances dictate that the number of parking spaces are determined by the size
of the business. Geology
is important to consider when designing stormwater retention areas. Karst areas
of Northern Arkansas don't filter the same as some areas, such as the Delta. More
pollutants are able to move through the water and contaminate groundwater in karst
areas. |

Arkansas Watershed Advisory Group Roundtable Discussion Summary Arkansas
Watershed Advisory Group Roundtable Discussion Summary "Sustainable
Development" October
3, 2002 Doubletree Hotel, Little Rock Start Time 9:00 A.M.. End Time
2:30 P.M.
The Roundtable Discussion was an action item resulting from the Arkansas Watershed
Advisory Group's (AWAG) goal statement II "to improve communication concerning
watershed resources." The AWAG sponsors an annual Roundtable Discussion that
promotes improved communications between government agencies and organizations.
The AWAG decided on sustainable development as this year's topic, and The Center
for Watershed Protection was asked to give several presentations that would promote
networking and discussion among the different agencies and organizations attending
the Roundtable Discussion. The AWAG also decided that they would invite a variety
of officials and leaders from local governments from across the State to participate
in hopes of new ideas being taken back to their communities.
Sandi Formica opened the Roundtable Discussion with a welcome and introductions.
Twenty-four representatives of the Arkansas Watershed Advisory Group attended
the Roundtable Discussion. Invited participants included: Jim Welch, City of Rogers;
Brian Day, City of Little Rock; Jim Larson, City of Little Rock; Gerald Cound,
Heifer International; Len Pardee, US Environmental Protection Agency, Region 6;
Ken Wasson, Arkansas Municipal League; Brenda Price and Paul Simms, Arkansas Highway
and Transportation Department; Randal Looney, Federal Highway Administration;
Larry Williams (Garland County) and Jack Jones (Jefferson County), County Judges'
Association of Arkansas. A total of 37 people attended.
Paul Sturm, Center for Watershed Protection (CWP), gave a presentation on "Better
Site Design Techniques." The discussion that followed focused on problems
in Arkansas including development in the floodplain. Major problems pointed out
during the discussion included flooding, erosion, and elevated peak discharge.
It was also noted that 1) many areas are seeing flooding occur outside the flood
plain area because of fill; 2) development of forested area is causing a concern
of fires; and 3) forested areas around housing areas should be managed and use
of conservation easements would help manage green areas.
Tom Schueler, CWP, gave a presentation on "New Advances in Stormwater Treatment."
After the presentation the need for more detention to treat stormwater was discussed
because cities are growing and constructing more highways. It was pointed out
that several states have installed stormwater retention sites. Ken Smith, executive
director of Audubon Arkansas, suggested that a demonstration site would be helpful
and that Heifer International is designing one. Bill Layher said that the new
Wal-Mart Super Center site in Pine Bluff will have stormwater retention ponds.
Some of the property will be donated to the city and will be developed as green
space with a riparian buffer zone along Bayou Bartholomew. The Bayou Bartholomew
Alliance will help manage the area. Judge Jack Jones of Jefferson County would
like detention ponds designed using recycled tires and aquatic plants to filter
pollutants that are washed into Lake Pine Bluff during heavy rainfall. Sand filters,
passive filters with a bio-organic layer on top were discussed. Tom Schueler said
that drying is not a problem, but they do clog. The city of Houston uses sand
filter but promotes wet ponds to filter pollutants from stormwater.
The Center of Watershed Protection gave two more presentations, "Changing
Development Rules in Your Community" and "Resources: To Make Things
Happen Locally." Jim Welch, City of Rogers, gave a lunch presentation titled
"City of Rogers Greenway Development" to give others an idea of what
is already being accomplished in the State. The three presentations gave Roundtable
participants plenty of discussion material. Tom Schueler, CWP, led the discussion
and some of the comments are listed below: Judge
Jack Jones, County Judges Association: Changing development rules will work in
areas where new development is occurring - trying to redevelop old areas that
are not growing will be more difficult. Jim
Welch, City of Rogers: Progressive community ordinances and policies must be implemented.
We all must change and adapt to more environmentally sound ways to do things. Bill
Layher, Bayou Bartholomew Alliance: The Delta has only floodplain ordinances and
no one is willing to enforce regulations. People living outside city limits do
not want to be forced to follow rules. Many say that is why they moved to the
country. Judge
Jack Jones: We don't have the money or resources to enforce rules. We are focusing
on trying to educate young people. Paul
Sturm, CWP: Use education techniques. There is a minority of vocal people who
are opposed to regulations. They do not reflect the majority of the people. Brian
Day, City of Little Rock: The city (Little Rock) is experiencing expansion. Many
people are opposed. Five acre subdivisions present major ordinance problems. Anne
Miners, Beaver Lake Watershed Partnership: Send letters to officials to have action
taken. Tom Schueler,
CWP: attend meetings at the county level. A simple approach to handling development
is to enforce existing codes, and get people who influence developers together
change bad codes. Judge
Jack Jones: Some counties are unable to enforce the FEMA floodplain plan. Tom
Schueler: There are plenty of paper ordinances, but we need checks and balances
to enforce the ordinances. Some things that seem radical now will be accepted
3 or 4 years down the road because of public outreach and education. Sandi
Formica, Chief of Environmental Preservation, Arkansas Dept. of Environmental
Quality, closed the Roundtable Discussion by encouraging participants to take
the information and ideas from the presentations and discussions back to their
communities. Additional

Arkansas Watershed Advisory Group Roundtable Discussion Summary Inn
of the Ozarks Eureka Springs, AR March 9, 2001 Morning
Session - Presentations from invited speakers on Total Maximum Daily
Loads (TMDL), Septic Tanks, and Phosphorus Index: The Roundtable Discussion
was scheduled to meet the established AWAG goals, specifically, Goal Statement
II, "To improve communication concerning watershed resources." The purpose
of holding the Roundtable was to help improve communications between resource
agencies. The agenda for the Roundtable is attached and contains a list of presentations
and speakers. Anne Hazlet was not able give her presentation "TMDL-Legal
Aspects," but John Harbison, professor at the University of Arkansas Law
School, was available to answer the group's legal questions concerning TMDLs.
Each speaker was introduced and then gave their presentation. All of the speakers
gave informative and excellent presentations on their topics. Some questions were
entertained between presentations, but most questions were saved for the afternoon
discussion Afternoon
Session - Discussion on Presentations and BMP Implementation Planning:
The group began their topics discussion during lunch and continued through the
first half of the afternoon session. The group asked all of the presenters many
questions concerning their topics, and overall an excellent and informative discussion
occurred between participants. Discussion
of TMDLs focused heavily on the need for additional data in order to correctly
prioritize potential sources of concern. Concerns discussed included the quality
of the data used during the TMDL generation process, concerns about whether the
data would be defensible, and if the data represented what is going on in the
field. It was noted that data quality is under scrutiny for TMDLs in other states. Although
there may be shortcomings in the data, the group discussed that the process of
TMDL development and implementation efforts would result in water quality improvement
and voluntary, phased implementation of BMPs is a process in which water quality
improvements can be made. One
participant noted that water quality standards are based on point sources, which
have the greatest impact during low flow conditions and that there may be some
need to define a set of standards for NPS contamination, which occurs at higher
flows. It was also suggested that source identification could be accomplished
based on the observations of local landowners. It was discussed, not necessarily
agreed upon, that source identification should be built into the TMDL process.
There was a
short discussion of septic tank systems. The Arkansas Health Department has estimated
that there is a 90% failure rate of anaerobic septic systems. It was pointed out
that improving septic systems should be considered a BMP for areas with high nutrient
loads and should be considered when evaluating and prioritizing potential sources.
It was stated that there were more failures of septic tanks in areas with high
seasonal water tables and flat soils, primarily South and East Arkansas. There
was also a short discussion on the Phosphorus Index. During the discussion it
was mentioned that there was a need for implementation monitoring. The Phosphorus
index is being utilized for the development of nutrient management plans. Incorporation
of manure into the soil structure is difficult. When incorporation is possible,
there is a concern of increasing sediment transport. The pasture renovation project,
an ADEQ/UofA project funded through an ASWCC 319 grant will look at the effect
of pasture aeration on phosphorus and sediment transport from pastures receiving
this BMP. BMP
Implementation Plan for the L'Anguille River: Bob Morgan led the second half
of the afternoon session. Copies of the L'Anguille River TMDL report by FTN Associates
had been available to attendees for review during the day. Bob
Morgan began this session by giving all attendees a list of items that a BMP Implementation
Plan should include: - List
of actions needed to reduce pollutant loadings
- A
timeline for implementing actions
- Reasonable
assurances of implementation
- Legal
authorities
- Estimate
of time to meet standards
- Monitoring
or modeling plan
- Milestones
for measuring progress
- Evaluation
plan
Bob
Morgan then asked for the group's input on what should go into the L'Anguille
River BMP Implementation Plan. A lot of discussion followed as individuals gave
their input on what should be in a BMP Implementation Plan, the purpose of a TMDL,
and what approaches should be taken when developing an BMP Implementation Plan.
Input from the group on the development of the L'Anguille River BMP Implementation
Plan included: - Collect
Data on sources, biological quality, water quality and hydrological data
- Characterize
the basin
- Start
local watershed group
- Detailed
data on land use (soils, slopes, BMPs in place, eroding banks, etc.)
