A Milwaukee-based oil recycling company was recently ordered by a judge to pay $140,000 in fines and other costs for 11 violations of state hazardous waste laws.
A 2009 inspection of Benz Oil Inc.'s Butler, Wis., facility found that tanks used to store hydraulic and other industrial oils were set on a gravel and clay surface, but state environmental regulations require the tanks to be placed on a concrete surface as part of a spill containment system, the Milwaukee Journal Sentinel reported.
Benz Oil also failed to investigate possible contamination despite puddles of liquid and oil stains underneath some tanks, the newspaper said. Waste oil from tanks might have contaminated the site.
The facility is now in compliance with state laws, the newspaper said.
Eight of the 11 violations involve business records, including a failure to notify state environmental regulators of its waste oil recycling activities from 1991 to July 2009 and failure to complete or update both spill prevention and emergency response plans, the newspaper said.
