Alabama Senate creates Permanent Joint Legislative Committee on Water Policy and Management

February 20, 2008

After a record drought that has been called the worst in some parts of Alabama in 100 years, legislators will attempt to develop a plan to manage the state’s rivers and other water resources.

The Alabama Senate passed a resolution Tuesday by state Sen. Kim Benefield, D-Woodland, to create the Permanent Joint Legislative Committee on Water Policy and Management. The committee would consist of members of the House and Senate and would present its initial report to the Legislature by the 15th meeting day of the 2009 regular session.

Rep. Greg Canfield, R-Vestavia Hills, said he would handle the resolution in the House.

The action in the Legislature comes as Alabama continues to suffer the effects of the drought, which has threatened to shut down industry and forced cities to take measures to protect water supplies. The drought intensified a long-running dispute between Alabama, Georgia and Florida concerning water usage.

The Georgia Legislature earlier this month passed that state’s first statewide water plan and it has been signed by Gov. Sonny Perdue.

At a State House news conference Tuesday, Benefield said the drought has shown that water resources can’t be taken for granted, even in Alabama with its extensive networks of rivers and lakes.

“I grew up on a farm in rural Randolph County. I can tell you from personal experience that crops without water do not survive,” Benefield said.

Canfield said he hopes the committee will borrow from some of the lessons learned in the Birmingham area, where communities adopted numerous water use restrictions and conservation plans during the drought.

“We have always viewed Alabama as a state rich in water resources. Today, Alabamians are painstakingly aware that this natural resource is not infinite in its availability,” Canfield said.

Gov. Bob Riley mentioned creation of a committee to study Alabama’s water resources during his “state-of-the-state” speech to lawmakers.

Jerry Sailors, co-chair of the Southeast Water Alliance, said the drought has emphasized how vulnerable Alabama is to water shortages. He said the Alabama River was closed to barge traffic through much of 2007, forcing industries along the river to spend thousands of dollars to ship goods and receive fuel and supplies by truck, rather than barge.

He also said several large industries along Alabama’s rivers came close to having to shut down because of low water levels.

“This drought underscored how much our daily lives depend on these waterways,” Sailors said.

Georgia’s Proposal To Redraw State Line Draws Criticism

8 02 2008

Georgia wants to push its border north to the Tennessee River to reach a water source for the drought-stricken Atlanta area. The border dispute dates to 1818.

In an article appearing in today’s issue of The Tennessean, Gil Rodgers, a staff attorney at the Southern Environmental Law Center, indicated that the proposal is the wrong approach to water woes. 

“Lawmakers,” Rodgers said, “should concentrate on conservation and sustainable development.  It’s a matter of how we grow and plan ahead so we’re not reduced to making these propositions about accessing rivers that are hundres of miles away.”

Georgia Loses Major Water Ruling

Georgia’s Deal For More Water Zapped

Wednesday, February 06, 2008

News Washington correspondent

WASHINGTON – An agreement giving Georgia rights to more of the water in Lake Lanier was thrown out by a federal appeals court Tuesday, a victory for the people and companies downstream in Alabama and Florida in the dispute over how the three states share water.

The now-defunct deal between Georgia and the U.S. Army Corps of Engineers would have increased the portion of the reservoir for Georgia’s drinking water supply from 14 percent to 23 percent.

The U.S. Court of Appeals for the District of Columbia said it was a big enough change to require congressional approval, which never happened, and is therefore invalid. The three-judge panel found that Alabama and Florida “credibly claim to fear” that the change would have diminished the amount of water available downstream for residents, industries and the environment.

Lake Lanier is about 50 miles northeast of Atlanta and feeds into the Chattahoochee River that runs along the eastern border of Alabama and Georgia.

The court ruling, which Georgia could appeal, alters the negotiating positions of the three states as the governors try to hammer out a settlement. Alabama Gov. Bob Riley said Georgia’s lock on such a significant portion of Lake Lanier was a stumbling block to those negotiations.

“This is the most consequential legal ruling in the 18-year history of the water war, and one of the most important in the history of the State of Alabama,” Riley said. “The ruling invalidates the massive water grab that Georgia tried to pull off.”

A spokesman for Georgia Gov. Sonny Perdue said he remains optimistic a settlement is possible.

“Our focus has always been to come to a joint agreement with our neighboring states and the Corps for how this basin is managed and operated, and that certainly is the same today as it was before,” said Bert Brantley. “This doesn’t change that in any way.”

The governors are hoping to reach a deal by mid-February, and meetings are ongoing.

However, Riley signaled that Tuesday’s court decision could be used to challenge other withdrawals by Georgia communities upstream in the two river basins that are at issue.

“It establishes that the decades-old practice of Atlanta taking more and more water from the federal reservoirs in the Coosa and Chattahoochee Rivers without any legal authority to do so will not stand,” Riley said.

In their 17-page opinion, the federal judges said that the Corps itself acknowledged that the 2003 agreement with Georgia involving Lake Lanier was the largest reallocation of water resources ever undertaken by the Corps without the approval of Congress.

“As I have long believed, and the courts have now validated, Atlanta is using more water than they are legally permitted,” said Sen. Richard Shelby, R-Ala.

Sen. Jeff Sessions, R-Ala., said he hoped the governors could strike a long-term deal. “Today’s ruling may be a turning point,” he said.





Water War Deadline Looming

6 02 2008

As the February 15th deadline for reaching a long-term water sharing agreement approaches, officials from Alabama, Georgia and Florida still have issues to resolve.

Check out these stories from this week’s Atlanta Journal Constitution:

Water War Deadline Looming

ATLANTA (AP) – Officials from Alabama, Florida and Georgia say
they are hopeful they will be able to meet a deadline this month to
come up with a plan to settle an 18-year battle over sharing water.
Florida Department of Environmental Protection spokeswoman Sarah
Williams tells The Atlanta Journal-Constitution that officials hope
to have a plan by February 15th.

A spokesman for Alabama Governor Bob Riley says he expects at
least “something of a compromise” even if all the issues aren’t
resolved by then.

A spokesman for Georgia Governor Sonny Perdue says the deadline
is still doable. Georgia Environmental Protection Division Director Carol Couch
would say only that staffers from the three states and federal
representatives have met twice in January.

The issue has been how much water to send downstream to Florida
from Georgia’s Lake Lanier at a time when metro Atlanta and north
Georgia are experiencing a record-setting drought. Georgia’s main
objective is to keep as much water in Lanier as possible.

Florida’s primary concern is getting enough water from Georgia’s
Chattahoochee and Flint rivers to flow into its Apalachicola River
to protect threatened and endangered species and maintain the
seafood and recreational fishing industries in Apalachicola Bay.

Alabama shares the Chattahoochee with Georgia on part of its
eastern border. It is much more interested in how much water is
flowing down the Coosa River. The Coosa basin provides water to
much of Alabama for hydropower and recreational lakes, to float
barges, and for drinking water and farm irrigation.

Lawmaker Seeks to Redraw Tenn. border to access water

Sen. David Shafer (R-Duluth) filed legislation Wednesday to change Georgia’s northwest border to force Tennessee to share its river with Atlanta. Shafer told his fellow senators that the federal government has repeatedly acknowledged that a flawed 1818 survey erroneously marked the boundary a mile south of its actual location.“The 35th parallel hasn’t changed. It is where it always is,” he said.

The resolution would push the border north of the southernmost bank of the 652-mile Tennessee river, currently managed by the federal Tennessee Valley Authority. The resolution creates two commissions made up of six Georgia lawmakers who would meet with counterparts from Tennessee and North Carolina to resurvey the border. Alabama also wants enough water flowing down the Chattahoochee
to run a nuclear power plant near Dothan.

Georgia loses major ruling on rights to Lanier water

It would take an act of Congress to get more drinking water out of Lake Lanier for metro Atlanta, a federal appellate court ruled Tuesday. Alabama and Florida immediately declared a major victory in the 18-year, tri-state water war, with Alabama Gov. Bob Riley calling it “one of the most important” legal decisions in his state’s history.The ruling invalidates the massive water grab that Georgia tried to pull off,” Riley said in a statement.

The decision by the U.S. Court of Appeals for the District of Columbia Circuit comes at a critical juncture, with the three states rushing toward a Feb. 15 deadline to reach a long-term, water-sharing agreement.

Observers say it gives Alabama and Florida leverage in the negotiations and belies metro Atlanta’s assumption that it can count on Lanier to continue fueling its growth. Water from Lanier, the largest federal reservoir on the Chattahoochee River, forms Georgia and Alabama’s southern border and winds up in Gulf of Mexico.

Lanier is the main water source for more than three million metro Atlantans. But it also supports multiple downstream users, from a nuclear power plant near Dothan, Ala., to oystermen in Florida’s Apalachicola Bay.

“The big loser here is metro Atlanta,” said George William Sherk, an expert in water law at the Colorado School of Mines who once represented the city of LaGrange and Troup County in tri-state water matters. “The logical response for metro Atlanta right now is no new building permits unless the applicant can demonstrate a long-term water supply.But pigs will fly before Atlanta does that.”

Sherk said Congress is unlikely to intervene.

Patricia Barmeyer, a partner at King & Spalding who represents metro Atlanta governments in the tri-state litigation, said the state and region has three legal options now: ask the three judge appeals panel to reconsider its decision; request a hearing from the entire D.C. appellate court; or take it to the U.S. Supreme Court.

The three-judge panel overturned a lower court’s decision. The appeals court nullified the 2003 agreement among Georgia, metro Atlanta, hydropower customers and the Corps of Engineers for rights to Lanier’s water. The corps manages the lake.

The agreement would have guaranteed the metro region about 65 percent more water out of Lanier for up to 20 years, or the equivalent of nearly one-quarter of the lake’s storage capacity.

Metro Atlanta now uses about 14 percent of the lake’s storage capacity.

In exchange, the cities and counties that depend on Lanier and the Chattahoochee just downstream would have paid $2.5 million a year to offset the costs of maintaining Buford Dam, relieving some of the costs now largely paid by hydropower customers.

Of the communities asked to pay more for their water, including Cobb, DeKalb and Fulton counties, Gwinnett County would have paid the lion’s share because it pulls the most water directly from Lanier, averaging more than 100 million gallons a day in the summer.

Frank Stephens with the Gwinnett County Department of Public Utilities said the decision will have little short term impact on the area’s water supply.

“From a city or county perspective, I don’t think this makes much of a difference but it does deny the U.S. government some revenues,” he said.

Georgia and metro Atlanta argued the corps was acting within its legal rights to reallocate Lanier’s water from hydropower generation to water supply.

Alabama and Florida disagreed, saying the change would constitute a major operational change, which requires Congressional approval under the Water Supply Act. The two states also argued that keeping water in Lanier for metro Atlanta’s use — and the region’s withdrawals — would reduce the water flowing down the Chattahoochee River.

In siding with Alabama and Florida, the court said “The Agreement does potentially reduce the amount of water flowing downstream. . . and the [Apalachicola-Chattahoochee-Flint river] basin would thereby be affected by changes to the quantity of water in the Chattahoochee River for as long as twenty years.”

The corps, during oral arguments in November, conceded that changing the amount Lanier’s stored water earmarked for drinking supplies from 47.6 billon gallons to 78.5 billion gallons would have been its largest reallocation of water without Congressional approval.

Gov. Sonny Perdue’s spokesman, Bert Brantley, said the ruling does not change the state’s long-term goal to reach a water-sharing agreement with Alabama and Florida, possibly by Feb. 15.

“We’ve always said our preference was to reach an agreement at the negotiating table as opposed to arguing it in the court room,” Brantley said.

He said the question of whether the corps can allocate more water for metro Atlanta will be resolved as part of the “bigger picture of how the basin is operated and managed.”

Barmeyer, the attorney representing metro governments, said the decision finally makes clear that a fundamental question will have to be litigated: whether providing drinking water to metro Atlanta was one of Lanier’s original purposes. The three states are currently locked in court action in the U.S. District Court in Middle District of Florida over longer-term allocations of water.

Georgia has spent nearly $5 million since 1998 on legal costs on the water war and metro Atlanta governments have spent about $2.4 million since 2001.

If the states are unable to come to terms by Feb. 15 — despite prodding from the White House — continued litigation is the most likely course.

That’s because Congress is unlikely to act on its own without a ready-made deal from the three states, said Sherk, the water law expert.

“Congress is not going to get into the internecine fight between Florida, Alabama and Georgia,” Sherk said. And if it does, Georgia could be in trouble.

“You only need eight states to win the presidency. Florida’s one of them. Georgia isn’t. Florida’s political clout dwarfs Georgia’s,” he said.

Alabama views Tuesday’s decision as a win as well for its most important river basin, the one it shares with Georgia’s Allatoona and Carters lakes, called the Alabama-Coosa-Tallapoosa basin. Allatoona provides drinking water to about 800,000 metro Atlantans.

In his statement, Gov. Riley said “The ruling will have far reaching consequences. It establishes that the decades-old practice of Atlanta taking more and more water from the federal reservoirs in the Coosa and Chattahoochee Rivers without any legal authority to do so will not stand.”

The ruling may also help downstream users in Georgia.

Joe Maltese, assistant to the LaGrange city manager and chairman of the Middle Chattahoochee Water Coalition that includes groups in Alabama and Georgia, said the ruling should bolster his group’s contention that the federally authorized purposes of all area lakes should be treated equitably, including recreation at West Point Lake near LaGrange.

“We don’t want to see Atlanta hurt,” Maltese said. “By the same token we don’t want to see the corps take away the resources that were promised to us to utilize the water for other purposes that Congress did not approve.”

THE STORY SO FAR:

The pressing issue: In 2003, Georgia and Metro Atlanta struck a deal with the U.S. Corps of Engineers, which operates Lake Lanier, that would have given metro Atlanta 23 percent of the water in the federal reservoir. Alabama and Florida challenged the agreement in court. The U.S. District Court for the District of Columbia upheld the agreement.

The history: The three states have squabbled since Alabama and Florida sued the corps in 1990 to stop metro Atlanta from taking more water out of Lake Lanier and the Chattahoochee River.

The stakes: Water got a lot more precious in the last year, as a record-breaking drought choked water supplies in north Georgia and much of the Southeast. Lake Lanier provides water to more than three million metro Atlantans and is essential to the area’s growth. Alabama needs water via the Chattahoochee for paper mills, a nuclear power plant and small communities, while Florida wants to protect its marine and wetlands ecosystems and oyster industry. Releases from Lanier also provides water needed by the federally endangered Gulf sturgeon fish and two species of federally protected mussels in the Apalachicola River, formed by the confluence of the Chattahoochee and the Flint rivers.

The new development: Tuesday, the U.S. Court of Appeals in Washington overturned the lower court’s decision, nullifying the 2003 agreement, which never became effective. The ruling says metro Atlanta and Georgia need Congressional authorization to take more water from the lake.

WHAT HAPPENS NEXT: The three states are negotiating a new division of water from Lake Lanier. Georgia, Alabama and Florida officials say they expect to meet a Feb. 15 deadline for an agreement. Georgia could decide to appeal the decision to the U.S. Supreme Court. Or Congress could step in.

Solar Energy Harvest Potential 

Have you been thinking of going solar? If so, one of the most important tasks you’ll undertake is determining just how much usable energy you will be able to produce, day in and day out, every month of the year. 

Fortunately, most of the guesswork has been removed from solar equations by the Analytical Studies Division at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. Compiled from data gathered over the 30-year period from 1961 to 1990, NREL’s Solar Radiation Data Manual for Flat-Plate and Concentrating Collectors gives a wealth of information about the solar radiation characteristics at hundreds of locations across the United States and its territories.

Using NREL’s Solar Radiation Data Manual and/or maps like the one above, you can get a feel for how much solar radiation (in kilowatt hours per square meter per day, or kWh/m2/day) will fall on your location, on average, during each day of any month of the year.
