Mr. Andy Plauche' and Ms. Esther Liggio represented the company during this inspection. Their report indicates that this facility appeared to be operating in compliance with applicable Louisiana Air Quality Regulations at the time of this inspection. However, the report indicates that during this inspection the following deficiencies were noted: 1) Fugitive dust emissions were observed in the Silicas Plant at a railcar loadout station during product loading and from the cleaning of a vacuum truck used for spill cleanup. 2) Recordkeeping required by Permit No. 2085 (M-l) pertaining to scrubbers and baghouses in the Silicas Plant should be revised to provide better documentation of control equipment maintenance inspection activities as required by the permit.
