Chris Irwin

KNOXVILLE — Join Chris Irwin and others to learn how to help track the origin of sediments and other pollutants in area waterways.

The meeting was postponed by snow and is now set for 7 p.m. Jan. 24 at Barleys, 200 East Jackson Ave., Knoxville.

“Spring is coming and with it rain and mud into the creeks and streams around Knoxville. We think a handful of people working together can stop a lot of mud going into the Tennessee River.

“This meeting is to show maps, a free app for gps pics, and a process to follow mud to its source so we can rat out the developers and others being sloppy with the health of our streams. We have the technology.”

Andrew Gunnoe helms spirited efforts to preserve beloved Little River but the current is swift

MARYVILLE — For 25 years, the handful of men and women involved with the nonprofit Little River Watershed Association (LRWA) have been protecting the crystal clear waters as they plummet from the Great Smoky Mountains before meandering through Blount County and merging with the Tennessee River.

“We see ourselves as the voice of the Little River, speaking for the river and its health,” said Andrew Gunnoe, president of the LRWA Board of Directors.

From the famous swimming hole at the Wye to the profusion of inner tube rental companies in Townsend, the Little River is one of the region’s most popular spots for water recreation. Further downstream, the waterway becomes an almost perfect spot for fishing, canoeing and kayaking.

For all the popularity as a recreation stop, the 59-mile stretch of water is also a vital habitat for numerous aquatic species and provides the 120,000-plus residents of Blount County with drinking water.

Georgia’s Ocmulgee River is a case study in the decline of Southern river fisheries, and their revival

Ethan Hatchett is a writer for the Georgia Department of Natural Resources.

MACON — The Ocmulgee River has changed. The cloudy water once ran clear. The sandy bottom was once rocky. Fish swam upriver to breed from places as distant as the Altamaha River, which the Ocmulgee and Oconee rivers join to form near Lumber City and the Atlantic Ocean.

European settlement changed the river. Centuries of agriculture and development stripped away much of the land’s vegetation that filtered the flow, causing the Ocmulgee to fill with sediment. The soil particles gradually moved through the waterway, covering gravel that fish spawned in, smothering fishes’ eggs, mucking up the water and even building up on the banks, saturating the ground with sediment.

It is impossible to know how many freshwater fish the Ocmulgee lost since the first Europeans arrived. Many species disappeared without being discovered. Yet on a clear afternoon in May, DNR aquatics biologist Paula Marcinek led a team on the upper Ocmulgee in search of robust redhorse, a “lost” fish found in 1991.

Read DNR’s blog post about efforts to restore the robust redhorse, plus news of a new grant that will expand the work and rare video of these fish spawning.

Tennessee Homebuilders Association and Tennessee Chamber of Commerce support reduced site inspections

Cindy Whitt and Judy Alexander, neighbors in the Westhaven subdivision in Williamson County for nearly 15 years, have watched their development grow from a small new-build subdivision of 500 homes to now more than 2,500.

In that time, on their regular walks together, they’ve also witnessed the results of dwindling green space as construction has surged:

“Almost everything from the construction runs through our storm sewer,” said Alexander. “Even though the developers put up fences (designed to prevent silt from escaping) all you need is a really steady rain — it doesn’t have to be heavy — and it all flows into our the Harpeth and the West Harpeth.”

The pair have contacted the Corps of Engineers, the city of Franklin and the state department of environment and conservation, but despite inspections, overflow ponds and new fencing, the problem persists.

“It blows my mind if we can’t even enforce the rules in wealthy Williamson County,” said Whitt, who worked for the Environmental Protection Agency in the 1970’s.

The women are now among more than 100 Tennessee residents who have voiced their opposition in public meetings and in written comments to proposed revisions to the permitting process for construction companies that Whitt fears will make the problems worse.

The proposed change by the state’s environmental regulators would roll back longstanding regulation for construction site runoff — rainwater that sweeps soil or other particles off site and into nearby waterways, often creating deposits of silt that impact water quality and aquatic life.

In an unusual move, a division within the Tennessee Department of Environment and Conservation  — the Division of Natural Areas — has weighed in to take issue with the permit change.
 
“We believe that sites assessments remain a key tool in understanding the character of a site and can provide documentation of ecological resources prior to commencement of construction,”  a staff member in the Division of Water Resources wrote to colleagues at TDEC.

Critics say new rules could run afoul of Clean Water Act

A state plan to rollback longstanding regulations for construction site runoff is drawing opposition from environmental groups who fear that Tennessee creeks and streams will suffer.

Stormwater discharges from construction sites — rainwater that sweeps soil or other particles off-site — can flow into nearby waterways, often creating silt deposits that impact aquatic life and water quality.

Historically, silt has been one of the primary pollutants in Tennessee’s waterways, a paper explaining the proposed new rules from the Tennessee Department of Environment and Conservation, or TDEC, said. Just one millimeter of soil spread over a one-acre site can weigh 5 tons, and “even a minor uncontrolled construction activity can cause major impairment in surface water,” through runoff, the paper said.

Nevertheless, TDEC is proposing significant changes in state environmental oversight of builders, developers, property owners, contractors and subcontractors in controlling runoff.

Developer of Maryville Pike property in South Knox County faces multiple state, county citations over alleged sediment pollution

The rapid growth of South Knox County has expanded far from the perimeters of the center city and extended into more development-rich areas.

One case in point: Significant development is taking place along a once-sleepy section of Maryville Pike between Vestal and Rockford.

There is a new entrance to the expanded I.C. King Park and its dog park and playground. Just south, one of the country’s largest home builders is finishing its Sevier Meadows subdivision.

There is another development that illustrates the growing pains and legacy costs that have prompted the county and Tennessee Department of Environment and Conservation to issue a stop-work order and levy multiple fines and citations against the current developer of the old Mayo seed warehouse site.

There are lessons to be learned from a small waterway called Flenniken Branch about the potential impacts of development on aquatic habitats and other public resources — and the ability of the government to protect those resources.

A troubled legacy

Decades of heavy industrial activity left a troubled environmental legacy near the Mount Olive community. Now a new 30-acre construction site is alleged by the state and county to be a significant source of sediment and debris that ultimately end up in the Tennessee River and its tributaries. The state also alleges the contractor buried a stream, and destroyed wetlands at another nearby property.

The Knoxville-based contractor, Kenn Davin, said he is working to correct the violations, but contends the alleged erosion violations are largely the result of runoff from nearby properties, and that the removal of trees from utility rights of way worsened the problem.

To make matters worse, one of those nearby sources of runoff, Davin said, is the so-called Witherspoon property, which was so contaminated by industrial waste the Environmental Protection Agency capped and sealed the site a decade ago.

The property in question is a 28.5-acre parcel at 2306 Maryville Pike, which abuts the Mount Olive Cemetery near Berry Road and was once the site of the D.R. Mayo Seed Co. warehouse.

Mayo sold the property in August 2019 to Florida-based CW Trust. Davin, principal at Knoxville-based contractor Design One, was designated as the site developer.

Over the course of the last 13 months, TDEC’s Department of Water Resources has issued three notices of violation for land disturbances and other impermissible activity at the Maryville Pike property.

The last notice was issued Nov. 20, 2020. Subsequent inspections in January and March noted that Davin was still out of compliance with action steps that had been required by the state.

Davin has not secured the permits required for the significant grading operations on the property, according to the county.

“They have not secured their necessary permits through our department for land disturbance,” said Knox County Stormwater Program Manager Natalie Landry.

Knox County Stormwater Management served a notice of violation for the 2306 Maryville Pike property on Feb. 9, 2021. The developer did not appeal, and a $500 civil penalty was levied.
