The Ohio Environmental Protection Agency has given the go-ahead for Apex to expand its landfill that has space in both Jefferson and Harrison Counties. The EPA issued Apex Environmental LLC a final solid waste permit-to-install and final air permit-to-install for the company’s proposed landfill expansion. This includes vertical expansion. However, Apex Environmental LLC will retain the existing 4-to-1 grade on the northern slope of the landfill. This means that the buried waste under 12 acres of the northern slope will not receive any new waste and will not need to be uncovered, preventing some potential odors.
