Lincoln Electric violated the requirements to operate its baghouses within a certain range of pressure drop or velocity pressure, to record the reading each day, and to report all deviations from the range to Ohio EPA. Lincoln Electric also violated its particulate emission standard at EU P904 for 31days. Lincoln Electric will install a state-of-the-art pressure drop monitoring system on all its emission units that are controlled by baghouses, and will also install bag break detection systems on several of the emission units. Additionally, Lincoln Electric will reduce the HAP and VOC emissions from its facility by replacing some of the coatings it uses with low-VOC and HAP-free coatings.
