DES MOINES -- Iowa Attorney General Tom Miller this week leveled water-pollution charges against a vacation resort similar to those he laid last month against an intensive egg farm.

Miller announced Wednesday that he had filed an environmental enforcement lawsuit (EEL) against a resort on East Lake Okoboji in northwest Iowa. The suit charges two water-pollution and one air-pollution violation.

The East Okoboji Lake region is officially designated a high quality water resource of Iowa. "We all must protect such precious resources," Miller stated in a press release.

The suit against Sioux Falls, S.D.-based Bridges Bay Resort LLC asks Dickinson County District Court to assess fines of $5,000 per daily violation on several water counts and $10,000 on one air count. The 20-acre resort contains condos, a hotel and water park.

Miller filed a similar EEL late last month against north Iowa egg producer Golden Oval Eggs LLC over alleged repeated water-pollution breaches, LegalNewsLine reported. He is seeking $5,000 per daily violation for effluent-limit breaches on the farm over 16 months.

The lawsuit against Bridges Bay alleges that silt run-off from the construction site was observed flowing directly into East Lake Okoboji several times between June 2005 and September 2006. It also charges a count of illegal burning last June.

Bridges Bay developer Jon Broek, of Sioux Falls-based Equity Homes, told the AP his company had voluntarily used low-impact development practices during the project.

Broek referred sarcastically to Miller's lawsuit as "a good way to make other developers run from low-impact-development" in Iowa.
