The state Department of Environmental Conservation tentatively determined CWM Chemical Services' application for an air quality permit is sufficient for its proposed hazardous waste landfill expansion in Niagara County.
The public will get its chance to weigh in on it through Sept. 22.
CWM is required to obtain air, water and other permits before moving forward with a proposed 44-acre expansion at it current hazardous waste landfill on Balmer Road in the towns of Lewiston and Porter.
"This is a piece of the overall process," said Lori Caso, spokeswoman for CWM.
The DEC said it "determined CWM is not a major source of criteria or hazardous air pollutants," in reaching its tentative conclusion to issue the permit.
