The pricetag for the new Interstate 74 bridge and corridor improvements may escalate to $1.4 billion -- more than double the projected cost in 2004 -- before the work is completed.

During the presentation to the Bettendorf City Council last week, Iowa Department of Transportation (IDOT) officials said the overall bridge/corridor work currently is estimated at $767 million, but by 2015 the cost is expected to increase to $1 billion.

Adding in inflation and a contingency amount for unanticipated cost increases between 2015 and when the work is actually completed, the total price for the bridge and highway upgrades could reach $1.4 billion, the IDOT said.

MidAmerican Energy wants to boost electric rates, and is proposing a first-ever "environmental compliance" adjustment clause to reflect those costs on customers' electric bills.

The privately owned utility says it plans to seek approval for an overall 3.5 percent rate increase in February 2012. Interim rates could be in place by March.

Rather than file a general rate case, the utility has outlined in filings with the Iowa Utilities Board (IUB) that it wants to add two automatic adjustment clauses for "environmental compliance" and "coal and coal transportation" costs.

Isle of Capri Casinos, Inc. lost $1.5 million in its second quarter ended October 23, while admissions at its Bettendorf casino were off nearly 5 percent for the quarter compared to a year ago.

Second quarter revenues for the Isle corporation were $247.5 million, up from $246.7 million for the same period last year. However, increased expenses resulted in the loss of 4 cents per share. A year ago, the Isle lost 3 cents per share ($1 million) during the second quarter.

Lee Enterprises -- owner of the Quad City Times and Muscatine Journal -- says it plans to file a "prepackaged" voluntary Chapter 11 bankruptcy plan by Dec. 12 as it moves to finalize a debt restructuring announced in September.

The newspaper chain said it wasn't able to get about 6 percent of its senior lenders to agree to the restructuring plan and needed to use the bankruptcy process to complete the refinancing deal. Lee's properties in Tucson, AZ and Madison, WI, are not part of the planned filing.

A Muscatine citizens' group says it will seek to intervene in the state's lawsuit seeking an injunction and civil damages against Grain Processing Company (GPC) for alleged violations of state and federal pollution laws.

Clean Air Muscatine (CLAM) is a non-profit corporation established for the purpose of protecting communities in Muscatine County from pollution.

Seven months after the Iowa Environmental Protection Commission recommended legal action against Grain Processing Corp. (GPC) for alleged violations of pollution control laws, the Iowa Attorney General's office filed a lawsuit against the Muscatine firm.

The lawsuit in Muscatine County District Court cites many of the same findings alleged in the environmental commission's April 19 recommendation.

The new Interstate 74 bridge may be at least a decade away, but the city of Bettendorf is being asked to commit an estimated $7.8 million for "aesthetic" improvements along the project corridor.

The memorandum of understanding outlining the financial commitments by Bettendorf, Moline, Davenport and the states of Iowa and Illinois is to be voted on at the December 6 council meeting.

The aesthetic components of the project total $46 million and include:

• The pedestrian/bike lane on the bridge.
• The pedestrian overlook planned for mid-span of the new bridge.

MidAmerican Energy spent $2.3 million on its nuclear plant feasibility study over the past 16 months, but has asked the Iowa Utilities Board (IUB) to keep details of most of those expenditures confidential.

The privately owned utility company was given approval by the legislature in April 2010 to collect a total of $15 million over a three-year period to pay for the nuclear plant feasibility study.

All 32 exceedances of national air quality standards in Iowa so far this year have been recorded in Muscatine.

The National Ambient Air Quality Standards (NAAQS) are levels of pollution considered "harmful to public health and environment," and include air pollutants ozone, sulfur dioxide, carbon monoxide, nitrogen oxide, lead and particulate matter.

As of Nov. 9, the air quality standard for sulfur dioxide (SO2) in Muscatine was exceeded 30 times and twice for particulate matter of less than 2.5 microns (PM2.5).

As it nears the end of removing nearly 300,000 tons of used foundry sand from its Bettendorf riverfront operation, Sivyer Steel has entered into a consent order agreeing to stay in compliance with regulations that permit no more than a six-month accumulation of the waste material on site.

The agreement signed Oct. 7 concludes a five-year period of discussions between Sivyer and the Iowa Department of Natural Resources (IDNR) over the foundry sand, used in making molds for casting steel at the facility.
