MLGW Again Declines To Name Power Bidders

Several Memphis environmental groups want to know what firms are bidding to supply the city’s electricity, but Memphis Light, Gas & Water (MLGW) said (again) they don’t have to share the information and won’t until the time is right. 

MLGW is in the midst of picking a power provider, either staying with the Tennessee Valley Authority (TVA) or selecting a new company. The local utility is now the largest customer of the TVA and has been with the authority for more than 80 years. The idea to move away from TVA has been around for a long time, but last year MLGW formally began a process to possibly find other suppliers with a request for proposals.   

Bids came back from nearly 20 companies, but when Sam Hardiman, a Commercial Appeal reporter, asked for company names earlier this year, MLGW declined to provide them, citing state law that says MLGW can keep the company names and their proposals secret.

The laws in question say MLGW can hold the records until recommendations for awarding the contract are submitted by staff to the MLGW board. MLGW said Friday it would adhere to that process.

But several Memphis groups asked MLGW to see the proposals again this week. The Southern Environmental Law Center (SELC) asked for the records in a Thursday letter to MLGW on behalf of the Sierra Club, Memphis Community Against Pollution, and Protect Our Aquifer, known collectively in the letter as “Community Groups.” The decision is a big one, the letter says, and the public should know who is involved. 

 ”Community Groups — and the Memphis community generally — lack access to crucially important information related to the more than 20 bids MLGW has received in response to the [requests for proposals]. Shutting the community out of the process is profoundly concerning in light of the significance of MLGW’s impending decision.”

In a Friday statement, MLGW again refused to provide that information.

”In accordance with state law and MLGW policy, the proposals received in response to those [requests for proposals] “shall not be open for public inspection’ until notices of an intent to award are issued,” the utility said. “Once recommendations for award are submitted by MLGW staff to the MLGW Board regarding an RFP, all proposals submitted in response to that RFP will be available to the public for inspection, except to the extent that any information included in those proposals is protected in accordance with federal and state law for proprietary and system security proposes. 

”Members of the public will have further opportunities to provide comments and input as recommendations are considered by the MLGW Board and the Memphis City Council.”

MLGW said public input was “instrumental” in completing its integrated resource plan to decide what sources of power it wanted to use. SELC’s letter agreed and urged that MLGW be as transparent as possible in its current proposal process.

The SELC was concerned that by keeping the other contenders secret, TVA’s incumbent status would be given an “unfair advantage” with the public. It noted that group members have received emails from TVA touting its proposal, read multiple news stories about it, and even saw ”TVA’s high-visibility co-sponsorship with MLGW to provide drinking water at the Beale Street Music Festival.”  

SELC asked MLGW to make a decision on sharing the records within a week.

New Coalition Urges Quicker Moves on Clean Energy

A new coalition launched last week urging the Tennessee Valley Authority (TVA) toward a fossil-fuel-free future by 2030, but the provider aims to get there by 2050 to ensure low-cost and reliable energy.

Dozens of organizations formed the Clean Up TVA Coalition (CUTC) last week. It includes environmental, social justice, and political groups like the Memphis NAACP, Southern Alliance for Clean Energy (SACE), the Sierra Club, Tennessee Interfaith Power & Light, the Center for Biological Diversity, and more

They formed CUTC in response to TVA’s move to replace coal-fired power plants in Kingston (East Tennessee) and Cumberland City (Middle Tennessee) with a new methane gas plant and 149 miles of new gas pipeline. Instead of investing in gas, the group wants TVA to invest in clean energy solutions to replace the coal plants.

“TVA is too reliant on fossil fuel energy and plans to continue to generate millions of tons of carbon,” said Pearl Walker, co-chair of the Memphis NAACP Environmental Justice Committee. “Households in the TVA footprint — especially Black, Brown, and low-wealth communities — will continue to be disproportionately burdened by high utility bills and dirty energy.”

In May 2021, TVA board members endorsed a plan to move toward net-zero emissions by 2050. The power agency has cut its carbon emissions by 63 percent since 2005. To get there, it added 1,600 megawatts of new nuclear capacity (the most of any utility in the nation, TVA said), added 1,600 megawatts of wind and solar capacity, planned to retire 8,600 megawatts of coal capacity by 2023, and invested more than $400 million to promote energy efficiency.

“The steps we’ve already taken operationally and financially have created a strong foundation for supplying cleaner energy without impacting reliability or low cost,” said Jeff Lyash, TVA president and CEO. “TVA is an industry leader in carbon reduction, but we aren’t satisfied. We are focused on increasing carbon reduction while maintaining our commitment to the low-cost, reliable energy our customers expect and deserve.”

TVA is on the path to cut carbon by 80 percent by 2035 without impacting TVA’s reliability or costs, Lyash said. It expects to retire all of its coal plants that year, using natural gas facilities as a “bridging strategy to effectively allow the addition of more renewable energy without impacting system reliability.”

But to get to net-zero carbon emissions will take new developments like energy storage systems, carbon capture, and advanced nuclear solutions.

President Joe Biden wants carbon-free electricity by 2035, according to an executive order he issued in December. Federal operations and federal procurements will be carbon-free by 2050, under Biden’s order.

Agency Aims to Fight Factory Farm Rules

Agency Aims to Fight Factory Farm Rules

Factory farms got looser laws thanks to state lawmakers last year but as that deregulation becomes a reality, some worry about the extra animal waste that comes with it.

On Monday, the Tennessee Department of Environment and Conservation (TDEC) heard from the public on water-quality regulations for concentrated animal feeding operations (CAFO), or large livestock farming operations.

Previously “medium-sized” factory farms that had as many as 699 dairy cows, 2,499 fully grown hogs, or up to 124,999 chickens had to get a state permit (SOP) if it met federal requirements, according to the Tennessee Clean Water Network (TCWN).

That permit required these operations to have a state-approved plan for the storage, use, and disposal of animal waste. 
Tennessee Clean Water Network

Two larges lagoons hold animal waste behind three barns on a factory farm.

Now, “medium-sized” factory farms like these don’t have to have a permit at all and no plan for its animal waste.

“The intent of the loophole legislation was to attract more businesses to Tennessee,” said Kathy Hawes, executive director of TCWN. “But factory farms that generate millions of pounds of animal waste are not the sort of businesses we want in a state known for its beautiful waterways.”

How much animal waste is generated by those medium-sized factory farms?
[pullquote-1] ”Imagine a packed Neyland Stadium at UT vs Alabama,” reads a statement from the TCWN. “If those fans were trapped in there for 24 hours, they would generate more than 200,000 pounds of waste.

“The same amount of swine in that stadium? Over a million pounds in one day.”

If improperly stored, animal waste at these farms can contaminate groundwater and run off into natural waterways like lakes, rivers, and ponds.

The Sierra Club says factory-farm waste produces more than 168 gases, including hazardous chemicals like ammonia, hydrogen sulfide, and methane. Airborne particulate matter found near them can carry disease-causing bacteria, fungus, or other pathogens. These farms are also home to “infestations of flies, rats, and other vermin.”

When the bill was debated in the Tennessee General Assembly last year, Rep. Tim Wirgau (R-Buchanan) a pork producer in his district had an operation worth more than $100 million.

“I have farmers in my district in West Tennessee, as you know it is the largest agricultural part of the state, and they are coming to me saying, ‘I don’t want TDEC in my business,’ Wirgau said.

See the full debate here:

Agency Aims to Fight Factory Farm Rules (2)

The new rules have been placed on public notice. The deadline to comment is July 25th.

“TDEC may have the last say when it comes to executing these laws, but TCWN will put its thoughts to paper first – for any Tennessean to read,” Hawes said. “TCWN will issue a comment letter about these rules to TDEC by their deadline date of July 25.”

TVA Plans to Remove Coal Ash from Allen Site

Southern Environmental Law Center

Aerial shots of TVA’s Memphis power plants.

UPDATE:

Shortly after TVA announced on Wednesday that it would remove coal ash from ponds at the Allen Fossil Plant, state Senator Brian Kelsey announced he’d filed a resolution calling for the removal of coal ash from ponds at the Allen Fossil Plant.

“Clean water is one of our most precious resources in West Tennessee,” said Senator Kelsey. “We should be doing everything we can to ensure that it remains safe and clean for future generations.

“Action must be taken to ensure that arsenic and other toxic compounds found in the coal ash landfill sites are not leaking into our water supply. It is essential that the coal ash containment ponds at the plant be emptied and closed as quickly as possible in the interest of public health.”

Senate Joint Resolution 29 asks the TVA to take action to ensure Memphis water is protected from a potential breach.

ORIGINAL POST:

The Tennessee Valley Authority (TVA) plans to remove the coal ash from its now-idled Allen Fossil Plant in Memphis.

TVA now has two coal ash ponds at the Allen plant and some coal ash around what TVA calls the metal cleaning pond. Coal ash is left behind after coal was burned to fuel the plant and make electricity. That ash, however, is toxic and arsenic and other chemicals have leaked into groundwater under the coal ash ponds at Allen.

TVA closed the ponds after it stopped using the fossil plant, switching to new plant that uses natural gas to make electricity. But the agency considered sealing the ponds and storing the ash in place. But TVA announced Wednesday that option is off the table.

Instead, TVA will consider options that remove the ash. They are now deciding where the ash will go.

One option has TVA building and using a “a proposed beneficial re-use facility to process (coal ash) materials. The other would move the ash in “to an offsite landfill location.”

Removing the ash, too, could make the “closure area land available for future economic development projects in the greater Memphis area,” according to a statement from TVA’s website.

“Bottom line is TVA does not own this property, and we think this is the best option for the future economic development options,” TVA spokesman Scott Brooks said in a statement.

Members of the local branch of the Sierra Club and the Protect Our Aquifer (POA) groups said the decision to remove the ash was a step in the right direction.

“Closure-in-place was never an option in mind, not in anybody’s mind,” said Ward Archer, president of POA. “That’s the equivalent of doing nothing, basically. It can’t be done. We all know there’s no protective clay layer below (the coal ash ponds). They have got to get (the coal ash) out of there.

Scott Banbury, the Sierra Club’s Tennessee chapter conservation programs coordinator, said the move was “great news.”

“We knew already their preferred option was to dig the (coal ash) up and move it somewhere else,” Banbury said. “It’s nice that they are saying that publicly.”

Legislators Want to Curb Local Control of Plastic Bags, Food Containers

Maya Smith

Plastic bags like these could cost you 4 cents apiece.

The Tennessee Chapter of the Sierra Club is seeking signatures to help stop bills in the Tennessee General Assembly that would ban cities’ abilities to put any restrictions on plastic bags and single-use containers.

The House version of the bill passed on the floor in that chamber Monday. The Senate bill is slated to be heard Tuesday in the Commerce and Labor committee.

The bill ”prohibits a local government from adopting or enforcing a resolution, ordinance, policy, or regulation that:

• regulates the use, disposition, or sale of an auxiliary container

• prohibits or restricts an auxiliary container or

• Enacts a fee, charge, or tax on an auxiliary container.”

“This [bill] provides that this state is the exclusive regulator of food and drink sellers, vendors, vending machine operators, food establishments, and food service establishments in this state,” reads the bill. “This [bill] prohibits a local government from imposing a tax, fee, or otherwise regulating the wholesale or retail sale, manufacture, or distribution of any food or drink, food or drink content, amount of food or drink content, or food or drink ingredients…”

The Sierra Club called the bill “horrible legislation” and said it “would take away local communities ability to enact any restrictions or fees on single use containers, bags or eating implements (straws).”
[pullquote-1] “Single use plastics clog our stormwater systems, pollute our waterways, kill wildlife, and eventually result in microplastics in our water supplies,” reads the Sierra Club website. “Local communities know best how to handle their unique challenges with single use plastics and unless the state wants to enacted a ban across Tennessee, the General Assembly should stay out of their way.”

As of Tuesday morning, the club’s petition had 700 of the 1,000 signatures the club is seeking.

The Memphis City Council paused a vote on a new, local fee on plastic bags earlier this month as the state legislation made its ways through the Assembly.

The fee here is meant to curb plastic bag usage to reduce litter, especially in the city’s waterways, according to council member Berlin Boyd, who sponsored the resolution here.

The fee was initially 7 cents per bag but was lowered to 4 cents. If approved, it would take effect January 2020.

County Health Department Limits TVA’s Use of Aquifer Wells

USGS

Groundwater discharge from an aquifer test at the Tennessee Valley Authority Allen Combined Cycle Plant in October.


The Shelby County Health Department placed rules on how the Tennessee Valley Authority (TVA) uses five wells at its Allen natural gas plant this week.

The health department prohibited TVA from using the wells, which the utility previously committed to not using, except in three circumstances:

Sampling for contaminants or studying the connection of the shallow and deep aquifers. Approval for the studies must be granted by the Tennessee Department of Conservation.


Using the plant for water in an emergency when Memphis Light, Gas & Water cannot provide it. This is to be done only to avoid “serious damage or disruption to the regional power grid.”

Limited Maintenance of up to 30 minutes each quarter.


These modified permits are in response to a December request to limit or prohibit TVA’s use of the wells by the Southern Environmental Law Center (SELC) on behalf of Protect Our Aquifer and the Sierra Club in order to avoid contamination of Memphis’ drinking water source.

The health department previously gave TVA permits to drill five wells into the Memphis Sand Aquifer in order to pump about 3.5 million gallons of water to cool its energy plant here.

After tests found high levels of arsenic and lead at the site, TVA said it would not use the wells until after a state investigation into groundwater contamination is completed.

A coal ash pond at TVA’s Allen Fossil Plant.

The five wells in question are housed in the Allen Combined Cycle Plant, which sits within a half-mile of a leaking coal ash pond operated by TVA. The ash pond is the center of ongoing state and federal investigations into groundwater contaminants, including arsenic and lead. Studies have suggested that use of the wells could put the Memphis Sand Aquifer at greater risk of contamination from the coal ash pond.

Research done by the University of Memphis and the U.S. Geological Survey last year showed that the coal ash pond is connected to the Memphis Sand Aquifer through gaps in the aquifer’s protective clay layers. The study also found that this connection could cause the contaminated groundwater to be pulled into the drinking water source when water is pumped from the wells.

Amanda Garcia, the senior attorney for SELC, said TVA should have never asked for the permits to use the wells, and that “we’re pleased to see that the county acknowledged, in a letter, that TVA would be denied permits to drill the wells if they had applied today.”

She added that the rules placed on utility’s usage demonstrates “how serious the pollution risk is to the county’s drinking water source.”

Ward Archer, president of Protect Our Aquifer, agreed, saying the county made the right decision in placing restrictions on TVA’s well use.

“Last year, the Shelby County Groundwater Control Board made the first step to better protect the Memphis Sand Aquifer by adopting stronger rules for obtaining permits and operating wells that pull from the Memphis Sand.

“However, we still need better local groundwater protections across the area and we hope Shelby County continues to work to conserve our most precious natural resource.”

Strickland Pondering City Action on Aquifier Dispute

JB

The Sierra Club ‘s Banbury and Mayor Strickland (seated) at recent Water Board hearing

Memphis Mayor Jim Strickland is researching local water-permit procedures with an eye toward giving the city some power of approval over future permits — and simultaneously to ascertain the city’s wherewithal under existing rules.

Strickland, an opponent of TVA’s plan to use water from the Memphis sand aquifer, source of the Memphis area’s drinking water, to cool a new power plant, had prepared to speak at the Shelby County Water Quality Control Board’s meeting two weeks ago in which the Sierra Club’s appeal of well-drilling permits for TVA was unanimously rejected. But he was informed the night before that the Board meeting, chaired by special presiding officer Bob McLean, was “not a public hearing” but a judicial one with strictly formalistic rules.

The Mayor was allowed to attend the hearing but only as a spectator, along with other members of the audience.

The outcome of that hearing has not sat well with Strickland or with other local public officials, including state Senators Lee Harris, a Democrat, and Brian Kelsey, a Republican, who oppose the drilling and have announced plans for bipartisan action to hash out the matter publicly.

And a freshly incorporated Protect Our Aquifer organization, including the Sierra Club, whose members regard the TVA drilling as potentially contaminating to the Aquifier water supply and whose appeal had prompted the Water Board hearing, plans to challenge the board’s decision in Chancery Court.

Scott Banbury, conservation program coordinator for the Sierra Club in Tennessee, plans also to suggest to the Shelby County Commission new and stricter rules for granting well permits, including more advance public notice regarding applications.

Water Quality Board Rejects Appeal of TVA Plans to Drill Into Aquifier

JB

Hearing officer Bob McLean (at microphone) spells out rules of procedure for Water Quality Control Board members.

It was a long day at the County Code Enforcement building at the Shelby Farms governmental complex, where TVA’s plans to drill into the Memphis sand aquifier were at stake, but the result — a 7-0 vote by the County’s Walter Quality Control Board against a Sierra Club effort to halt those plans — made unexpectedly short work of an issue that was expected to fester for a while.

Testimony at a Board hearing of an appeal that would have spelled quietus on the final two of five wells envisioned by the Authority began at roughly 9:30 and ended at 5 with a motion from Board member Tim Overley, utilities director for Collierville, to reject the appeal. The vote was by a show of hands at the direction of hearing officer Bob McLean. There were three recusals for various reasons on the 11-member board and one absentee.

The outcome apparently leaves TVA free to continue with its preparations to draw some 3.5 million gallons a day from the aquifier to use as coolant for its forthcoming natural-gas power plant, scheduled to open in 2018 as a replacement for the coal-powered plant it currently operates.

The Sierra Club’s Scott Banbury, backed by a coalition of environmentally minded citizens and organizations, had filed an appeal in September to reject permits issued by the county’s Health Department for the two wells. Three wells had already been drilled — before public notice had been given, said Banbury — but have not yet been outfitted with pumps.

TVA maintained that it needed the five wells to provide the plant’s core function of serving 1.5 million customers in the Greater Memphis area, that alternatives of using water from the area’s Maxson wastewater plant or the Mississippi River alluvial aquifier or even of purchasing water from the sand aquifier from MLGW were all considered but finally deemed insufficient for the purpose.

The environmentalists supporting the appeal via an organized “Protect the Aquifier” movement spearheaded by advertising executive Ward Archer have argued that the all of the discarded alternatives were feasible and that the Authority’s plan to drill into the sand aquifier was both unnecessary and endangered the famously pure drinking water with the prospect of pollution through rifts in the aquifier’s surrounding clay walls.

That case was made on Wednesday by Banbury, supplemented by supportive scientific documents placed on the record and by the videotaped testimony of Brian Waldron of the University of Memphis, but a rejection of the appellants’ motion for a continuance resulted in the exclusion of direct testimony from Waldron and other experts, all of whom were attending a professional conference in Ecuador.

JB

Appellant Scott Banbury talks with Memphis Mayor Jim Strickland before hearing.

Meanwhile, both the Health Department and TVA were able to boast a full array of witnesses supporting the Authority’s contention that the aquifier wells were necessary, were harmless to the environment, and had been properly vetted through accepted county-government procedures.

Ironically, the Shelby County Commission is due shortly to consider changes in those procedures (a course called for as well on Wednesday by a member of the Water Quality Control Board), and the Memphis City Council has passed a resolution calling for TVA to employ a different method to acquire its source of coolant water. Memphis Congressman Steve Cohen had also weighed in for a change in course.

The appellants had discussed in advance the possibility of appealing a negative finding by the Board through Chancery Court but have not yet decided whether to pursue that avenue.

The hearing on Wednesday was conducted to make it as close to a pure legal process as special hearing officer McLean could make it — complete with formal objections that could be sustained or overruled — and as far as possible from anything resembling a pure policy discussion. The audience — which included numerous members of the “Protect the Aquifier” movement, some wearing identifying T-shirts — was expressly warned against any form of demonstrations.

(For the most part, that injunction held, though from time to time a female audience member in the back of the room would respond with a discernibly sardonic chuckle to what she apparently saw as unintentionally revealing moments of testimony from TVA witnesses.)

A participant on the Health Department/TVA side characterized the process as being one of “rules versus emotions,” and the result of that emphasis was that discussion was steered away, over and over again, from ecological matters per se to the more limited question of whether the Health Department had followed checklist guidelines in making its preliminary decision to grant permits for the proposed TVA wells.

McLean’s conduct of the hearing seemed generally even-handed, particularly in his predisposition toward overruling objections, most of them from TVA lawyers attempting to disqualify testimony or exhibits from the Sierra Club side.

But there were anomalies. Early in the proceedings, Banbury attempted to make a point about the nearness to the Presidents Island TVA plant site of an area pinpointed in a U.S. geologic survey as a weak point in the clay layer surrounding the Memphis sand aquifier.

Asked by attorney Webb Brewer to specify exactly how close, Banbury began to answer, stating as his educated “guess,” based on familiarity with the area, that the exact distance was something like a mile, but was sharply interrupted by McLean, who said, “No guessing, Mr. Banbury!” and discounted the answer.

Somewhat later, Ron Tibbs, general manager of major projects for TVA, was at the witness table, and more than once phrased an answer to a technical question as a “guess” without being similarly cut short.
(One answer by Tibbs, to a cross-examination question from Brewer asking his evaluation of the pollutant nature of coal ash, one of the byproducts of TVA’s current power plant identified by environmentalists as toxic, brought a gasp or two from the audience, along with an instance of the aforementioned stage laugh from the back of the room. “I don’t consider coal ash to be particularly dangerous,” Tibbs said. “I’m not aware of any major concerns.”)

Many of the issues discussed in Wednesday’s hearing engendered Rashomon-like differences in perspective by the contending parties. The unusually large energy-producing capacity of the forthcoming new TVA plant — planned to be considerably more than sufficient for the needs of the target population — was explained away by Authority witnesses as being based on redundancy safeguards, while Sierra Club spokespersons have seen it as obvious evidence of TVA’s desire to expand its potential energy market beyond the current confines.

And there were intriguing questions left short of full exploration — such as why it was that “gray water” (i.e., treated waste water) was sufficient to cool the Authority’s Caledonia power plant near Columbus, Mississippi, but was regarded as out of the question for the forthcoming new plant here.

By and large, members of the Water Quality Board, many of whom held positions of engineering or environmental authority within Shelby County were respectful of the contending points of view at the hearing but, as their occasional questions to witnesses indicated, seemed inclined to give the benefit of the doubt to the testimony put forth by experts from the Health Department and TVA.

In any case, their verdict was, as indicated, more a statement of approval that established procedures were followed in the Health Department’s granting of permits for the proposed TVA wells than it was an evaluation of the Authority’s contention that no other alternative existed than the one of drilling into the Memphis sand aquifier.

Shelby County Commission Wants to Study New Rules for Drilling Wells into Aquifer

TVA is replacing the Allen coal plant (above) with a new gas plant, and they’re looking at drilling wells into the Memphis Sand aquifer to cool that new plant.

The Shelby County Health Department has already issued three permits to the Tennessee Valley Authority (TVA) to drill wells into the Memphis Sand aquifer to access cooling water for its new gas-powered Allen Combined Cycle plant.

Two more permits for wells are being considered, but at a Shelby County Commission committee meeting on Wednesday morning, Commissioner Steve Basar asked the Health Department not to issue those permits without coming to the commission first. Basar and Commissioner Heidi Shafer also recommended the formation of a committee that would look at updating the codes for drilling wells into the aquifer — the source of the region’s drinking water.

“What was acceptable 10 to 20 years ago may not be acceptable now. We need to evolve and move on and change the way we’re doing things,” Basar said.

At that meeting, Bob Rogers, manager of the Health Department’s pollution control program, told the commission that current codes say that if a company or resident wants to drill a well and has the proper design and installation plan, the department generally issues a permit. He said there are some restrictions, including a restriction on water use for non-circulating systems, meaning the water is used and discarded.

At issue are the permits TVA has requested to drill into the Memphis Sand aquifer for up to 3.5 million gallons of water per day to cool the new, under-construction gas plant. In 2014, when the TVA approved plans for the Allen Combined Cycle gas plant that will replace the Allen Fossil coal plant in 2018, they said they’d be using wastewater from the nearby Maxson Wastewater Treatment Plant for its cooling water system.

But those plans have turned out to be too expensive, according to a report from TVA, since using wastewater would first require treatment due to pollutants in that water. The TVA looked a few alternatives  — either drilling five wells into the aquifer and pulling water directly from the ground, purchasing potable water from Memphis Light, Gas, & Water (MLGW), or some combination of the two. If potable water is purchased from MLGW, that water would come from both the Memphis Sands and the Fort Pillow aquifers, but the TVA environmental assessment report says MLGW cannot sell the TVA enough water to meet peak demand.

The TVA published a supplemental report on those proposals in April, but the entity did not seek public comment. That’s not required by law, but TVA did seek comments for its original report detailing the options for switching from a coal plant to a gas plant.

Scott Banbury, conservation program coordinator for the Tennessee Sierra Club, spoke at the county commission meeting, and he said those new codes should include public notice for drilling permits. 

At a Sierra Club-hosted panel discussion on the issue in August, MLGW President Jerry Collins told the crowd that if TVA had to take water from the aquifer, he’d prefer the entity buy potable water from MLGW rather than pump directly. Either way, it comes out of the aquifer, but Collins said a purchase from MLGW would allow for more oversight.

“That would keep your rates low, and we could monitor how much they’re using. Also, we take out the iron and add phosphate, which makes it much less corrosive,” Collins said at that panel meeting. 

At the Shelby County Commission committee on Wednesday, Tyler Zerwekh, administrator of environmental health services for the Health Department, revealed that the department has issued 25 well permits in the past 12 months, and that includes wells for residential and industrial use. In total, there are 841 quasi-public wells (meaning at least some of the water is for public use) in 641 locations. That does not include wells for residential use.

Environmentalists Question TVA’s Plan to Drill Wells in Aquifer

Justin Fox Burks

The TVA is replacing the Allen Fossil Plant with a new gas plant.

The Tennessee Valley Authority’s (TVA) proposal to pull 3.5 million gallons of water per day from the Memphis Sand aquifer to cool its new under-construction gas plant is under fire by local environmentalists, many of whom showed up to a Sierra Club-sponsored public forum on the matter Thursday night.

About 100 people showed up to the meeting at the Benjamin L. Hooks Central Library to express concern over the plan to use Memphis’ clean drinking water to cool the TVA’s gas plant. 

“In my opinion, this is not a good use of our drinking water,” said panelist Brian Waldron, the director of the University of Memphis’ Center for Applied Earth Science and Engineering Research.

In 2014, when the TVA approved plans for the Allen Combined Cycle gas plant that will replace the Allen Fossil coal plant in 2018, they said they’d be using wastewater from the nearby Maxson Wastewater Treatment Plant for its cooling water system. But those plans have turned out to be too expensive, according to a report from TVA, since using wastewater would first require treatment due to pollutants in that water.

Now, they’re looking at a few alternatives — either drilling five wells into the aquifer and pulling water directly from the ground, purchasing potable water from Memphis Light, Gas, & Water (MLGW), or some combination of the two. If potable water is purchased from MLGW, that water would come from both the Memphis Sand and the Fort Pillow aquifers, but the TVA environmental assessment report says MLGW cannot sell the TVA enough water to meet peak demand.

The TVA published a supplemental report on the proposals in April, but the entity did not seek public comment. That’s not required by law, but TVA did seek comments for its original report detailing the options for switching from a coal plant to a gas plant.

“Had they opened it for comment, we would have offered alternatives,” said panelist Scott Banbury, conservation program coordinator for the Sierra Club.

Some of those alternatives were discussed by panelists at the meeting. MLGW president Jerry Collins sat on the panel and told the crowd that if TVA had to take water from the aquifer, he’d prefer the entity buy potable water from MLGW rather than pump directly. Either way, it comes out of the aquifer, but Collins said a purchase from MLGW would allow for more oversight.

“That would keep your rates low, and we could monitor how much they’re using. Also, we take out the iron and add phosphate, which makes it much less corrosive,” Collins said. 

Collins did say that the aquifer is in better shape than it was 16 years ago. In 2000, the average amount of water pumped from the aquifer daily was 159 million gallons. Last year, 126 million gallons per day were pumped. Collins credited that drop to regional water users becoming more environmentally conscious and installing low-flush toilets and more energy efficient washing machines and dishwashers.

Waldron said he’d prefer the TVA take its cooling water from the Mississippi River Valley alluvial aquifer rather than the Memphis Sand. He also warned of a known breach in the Memphis Sand that he believed could cause damage to the water supply if TVA went through with its plans to pump water directly from the aquifer.

Angela Garrone, an attorney for the Southern Alliance for Clean Energy, pointed out that if TVA would dedicate more resources to renewable energy, it wouldn’t need so much water.

“Solar and wind don’t need water and don’t have much of an impact on our environment,” Garrone said.

She also said the TVA should be doing a better job to engage the public on the matter.

“The TVA is a federal entity, not a company. I would think it would be in their best interest to engage the public,” she said. 

The TVA is still in a decision-making mode about what to do, Collins said. But several environmentalists from the Sierra Club are planning to attend the TVA’s board meeting on August 25th in Knoxville to express their concerns. Memphis City Councilman Martavius Jones said he may introduce a resolution in support of the TVA considering other alternatives at the next council meeting.

The TVA is under an agreement with the Environmental Protection Agency and several environmental groups, including the Sierra Club, to reduce emissions at its coal-fired plants by December 2018. In 2014, the TVA’s board voted to close the Allen Fossil plant, which provides energy to the region, and replace it with a more environmentally friendly natural gas plant. The new Allen Combined Cycle plant is currently under construction in Frank C. Pidgeon Industrial Park, near the site of the Allen Fossil Plant.

The TVA must have the Allen Fossil Plant closed by December 2018, so they’re looking to get the new plant online by June of that year.
