Indiana Moves to Reduce Pollution of Lake Michigan

Anglers, environmentalists and many others are pleased with a recent decision by the Indiana Department of Environmental Management (IDEM) to reduce pollution of Lake Michigan and its fisheries.

A stricter IDEM permit requires BP’s Whiting oil refinery, just outside Chicago, to lower its mercury discharges from 23 parts per trillion to 8.75.

“We are pleased the agency responded to our recommendation by strengthening the mercury requirements and requiring BP to submit and update its stormwater plan,” said Lyman Welch of the Alliance for the Great Lakes. “Still, we are disappointed that IDEM did not go as far as we’d hoped to protect the waters of the Great Lakes.”

At BP, meanwhile, spokesman Scott Dean said that new technologies for pollution reduction are promising.

“BP is committed to protecting Lake Michigan and we are cautiously optimistic that our recent investment in new water treatment equipment will further reduce the Whiting Refinery mercury discharge,” Dean said. “Having said that, the mercury limit in the revised permit has decreased by more than half and the refinery needs to gain experience operating the new equipment before we will know if the refinery can successfully and consistently meet this revised limit.”

The company has almost completed a $3.8 billion expansion that will make it a top processor of heavy crude oil from Canada’s tar sand deposits. Following announcement of construction in 2007, IDEM allowed BP to increase its discharge of mercury, ammonia, and suspended solids.

Public outrage over that decision convinced BP to abide by stricter standards for ammonia and dissolved solids. But Indiana allowed an exemption for mercury as the company worked on technology to scrub its waste of that pollutant.

Separation Still Not Considered an Option for Keeping Carp out of Great Lakes

The latest manifestation of a strategy by the federal government to keep Asian carp out of the Great Lakes carries a $50 million price tag but still no mention of separating the lakes from the Mississippi River basin.

That omission does not please a growing number of stakeholders who believe that the only way to keep the exotics from destroying Great Lakes fisheries is by eliminating the manmade connection between the two watersheds.

“I think we could take carp control more seriously by disconnecting the Chicago waterway,” said Jim Diana, director of Michigan Sea Grant and a fisheries professor at the University of Michigan. “In absence of that, we’ll have all these kinds of temporary solutions that might work.”

And just a few months ago, Illinois Gov. Pat Quinn said, “Ultimately, I think we have to separate the basins. I really feel that is the ultimate solution. We have to do it.”

Until that announcement at a meeting of Great Lakes governors, most thought that Illinois would continue to side with Chicago and the Obama administration in opposing disconnection of the waterways.

Although it doesn’t include separation, the new 2013 Asian Carp Control Strategy Framework does call for an improved electric barrier south of Chicago, as well as creation of barriers at other tributaries feeding the lakes, nearly two dozen of which have been identified as potential entry points. It also calls for expanded sampling and emphasizes testing of new tools, including water guns, netting, chemical controls, and pheromone attractants.

“This strategy continues our aggressive effort to bolster our tools to keep Asian carp out of the Great Lakes, while we work toward a long-term solution,” said John Goss of the White House Council on Environmental quality, who oversees the initiative.

“The 2013 framework will strengthen our defenses against Asian carp and more innovative carp control projects from research to field trials to implementation.”

Asian Carp More Adaptable Than Previously Thought

Researchers from Purdue University have made some unsettling discoveries regarding Asian carp.

“It looks like the carp can probably become established in a wider range of environmental conditions than once thought,” said Reuben Goforth, an assistant professor of forestry and natural resources.

Goforth and associates learned that the exotic invaders are spawning in waters previously thought too narrow or slow moving. That means even more sport fisheries are at risk.

On a semi-positive note, he added, ‘’While the presence of eggs indicates a successful spawning of these fishes in new areas, it’s not known yet whether those eggs would be successful in surviving to adulthood.”

Additionally, they found evidence of carp spawning far upstream and eggs drifting in water as late as September in Indiana’s Wabash River. Previously, reproduction was thought to end in July.

Until now, most information related to where Asian carp might spawn was based on data gathered from their native habitats in Asian rivers and streams.

“The reason truly invasive species are so successful is because they overcome obstacles,” Goforth said. “When you base their limitations on what happens in their native ecosystems, it’s a good start. But it may be a good idea to go back and take this new data to recalculate more precise limits based on these new understandings.”

Support Grows for Separation 

Those who want to protect the Great Lakes from Asian carp invasion by removing the manmade connection between Lake Michigan and the Mississippi River basin have a new ally.

Illinois Gov. Pat Quinn surprised many when he endorsed that solution during a meeting with other governors here.

“Ultimately, I think we have to separate the basins,” he said. “I really feel that is the ultimate solution. We have to do it.”

Chris Kolb of the Michigan Environmental Council called Quinn’s remarks “a very positive step forward.” And Michigan Gov. Rick Snyder said, “I think it’s great to see people talking about longer-term solutions.”

In the past, Illinois sided with Indiana, the city of Chicago, and the Obama administration in opposing the separation. They argued that closure would increase flood risks, while damaging tourism and commerce.

“It’s important that we deal with this issue, but it’s also important that we deal with it in a way that preserves the logistical advantage and opportunity to move commerce through the region,” said Indiana Gov. Mike Pence.

But Michigan, Wisconsin, Minnesota, Ohio, and Pennsylvania have long favored the strategy and even sued the U.S. Army Corps of Engineers and Chicago’s water district. In a suit they lost, they claimed that refusal to separate the watersheds created a public nuisance.

The strongest argument for closing the aquatic highway, though, is that an explosion of Asian carp in the Great Lakes could decimate the system’s fishery, worth an estimated $7.5 billion annually. Additionally, the connection leaves the way open for other invasive species to cross watersheds.

The connecting canal was constructed more than a century ago, to allow Chicago’s sewage pollution to flow downstream, instead of contaminating the city’s Lake Michigan water supply. It also allowed for commercial navigation.

Asian Carp Infestation Worst in Mississippi, Missouri Basins

USGS bighead carp distribution map

Asian carp have been found in fisheries from Colorado to New Jersey and from North Dakota to Florida, according to a map released recently by the U.S. Army Corps of Engineers, the U.S. Geological Survey, and the Illinois Department of Natural Resources.

 “Asian Carp Distribution in North America” displays the presence of bighead and silver carp at all life stages, as well as black carp and grass carp occurrences. Since three bighead carp have been collected in the western basin over the years by commercial fishermen, Lake Erie is one of the green shaded areas, which indicates the presence of at least one adult fish. (This is not the map shown above. Go to link to see more detailed map.)

Not surprisingly, the most intense infestation is in the Mississippi and Missouri River watersheds, including the Illinois River, which connects to Lake Michigan via the Chicago Sanitary and Ship Canal.

On the positive side, no Asian carp have been found above the canal’s electric barriers during the past two years, despite hundreds of interagency monitoring trips, including 192 hours of electrofishing and 82 miles of netting.

But on the southeast side of the Mississippi River watershed, meanwhile, Asian carp are a growing problem for the Tennessee River and especially Kentucky Lake.

"Asian Carp by the thousands are flooding Kentucky Lake, causing a problem for fishermen, regular boaters and the other fish. With no natural predators the Asian carp are single-handedly eating the entire food supply, reports WBBJ.

Threat to Fisheries From Asian Carp, Zebra Mussels Continues to Grow

Zebra mussels can hitchhike from one fishery to another on outboard engines.

More bad news regarding aquatic invasive species. So what else is new?

First, the U.S. Geological Survey says in a June 18 report that four tributary rivers of the Great Lakes have conditions conducive for successful spawning by Asian carp. They include the Milwaukee and St. Joseph Rivers on Lake Michigan and the Maumee and Sandusky Rivers on Lake Erie.

Of course, the Asian carp must enter the Great Lakes first --- if they haven’t already.

Regarding that situation, a little good news does exist: The governor of Illinois says that he is in favor of severing the manmade connection between the Lake Michigan and the Mississippi River basin.

“Ultimately, I think we have to separate the basins,” Pat Quinn said. “I really feel that is the ultimate solution.”

Until now, Illinois has sided with Chicago, Indiana, the Obama administration, and commercial navigation interests in opposing separation. Most of the other Great Lakes states want separation to protect the system’s billion-dollar fishery from Asian carp.

Additionally, separation would prevent migration of other invasive species in the future into and out of the Great Lakes.

The second piece of bad news is that a live zebra mussel has been found in Texas’ Lewisville Lake, less than a year after an established population was confirmed in Lake Ray Roberts, just a few miles to the north. Likely the mussel was brought in on a boat hull or trailer, but it could have drifted down the Elm Fork of the Trinity River.

Mussel colonies can clog water intakes, costing metropolitan areas like Dallas/Fort Worth millions of dollars in maintenance costs over time to protect water supply reservoirs.

No matter where they are fishing, anglers should conscientiously inspect their boats and trailers when leaving a lake or impoundment to be certain that they are not about to transport these shellfish and other invasives.  If voluntary compliance isn’t enough to stop the spread, access restrictions inevitably will follow.
