The DNR says the spill wasn't reported for at least 7 hours after it was discovered at around 7 a.m. Nov. 4.
On Dec. 9, Iowa Citizens for Community Improvement sent a letter to the DNR demanding the state fine the company the maximum allowed and refer the case to the Attorney General's office for consideration of additional penalties.
ICCI, a grassroots community organization that opposes large-scale livestock farms, also wants the DNR to issue a Clean Water Act permit "so that this facility is either forced to play by stronger rules or is shut down."
ICCI and the Humane Society of the United States on Nov. 21 filed a notice of intent to sue the Maschhoff farm if the DNR doesn't issue a water permit within the 60 days, which would be late January. ICCI spokesman David Goodner said the Maschhoff response to the DNR indicates the company isn't accepting responsibility.
"If it's a fight they want, it's a fight they're going to get," he said in an interview.
Maschhoff said many of the group's criticisms are "patently false" and slanderous. She said the threatened legal action it is frivolous and without merit.
