Lakeside Lithography failed to maintain the temperature required in its federally enforceable construction permit on 134 separate dates on the catalytic oxidizer controlling Coating Line 2 at the Chicago facility. Lakeside?s failure to maintain the required temperature was discovered during a review of temperature records that had been requested by EPA.
This ACO requires Lakeside to install temperature alarms on the catalytic oxidizers to notify personnel of temperature excursions, discontinue use of Coating Line 1 unless there is a catalyst replacement on the catalytic oxidizer servicing that line, conduct catalyst activity lab analyses on the catalyst for Line 2, and submit reports on the status of compliance with the ACO.
