Last fall, under the direction of the Kentucky General Assembly, Louisville city officials pulled the plug on the VET test.
But environmentalists filed suit, claiming the Vet could only be ended with the approval of the federal Environmental Protection Agency, and federal District Judge John Heyburn agreed.
Heyburn informed both sides of his decision on Wednesday.
Originally, the plaintiffs had hoped the judge would slap the city with fines totaling over $1.7 million.
In addition to the $100,000 fine, the judge also ordered the air pollution control district to pay $30,000 in court costs.
Under the judge's decision, the Kentucky Resources Council, which brought the original suit, will receive the $100,000 from the Louisville Metro Air Pollution Control District.
A spokesman for the Kentucky Resource Council says the money will be used to promote improving air quality.
City attorneys had wanted the state to share in the federal penalty since the General Assembly ordered the /files/storyimages/of the VET, but the judge plans to only fine the city.
