New regulations passed by the state Environmental Quality Council do not address the issue of burning scrap tires at Ash Grove Cement Company at Louisville.
That has disappointed those who wanted the matter taken up.
State Department of Environmental Quality officials said the burning of scrap tires as fuel is adequately addressed by the state's air quality laws and does not need to be addressed through scrap tire rules.
Ash Grove is seeking permission from the state to burn a million scrap tires a year in its kilns as a supplemental fuel. It currently burns coal.
Opponents say the practice would further pollute the air and that the state needs new regulations to protect public health.
Many of the dozen or so people who testified Friday asked the council to delay a vote or scrap the revisions entirely.
The council voted 12-0 to approve the new regulations.
