### "A" Page 73 Multi-Purpose Plant Insignificant sources. The first item should read Three vacuum pumps . In addition, Croda requests that the General Emission Limitation from APC-2004/0723 for Oxides of Sulfur not to exceed 0.1 ton per 12-month rolling period be transferred to AQM-003/00426 - Renewal 2. In addition , Croda requests that the Emission Limitation from APC-2004/0723 for Carbon Monoxide of 34.0 pounds per batch for the 'Kettles Area' be transferred to AQM-003/00426 - Renewal 2 and whilewe request 34 .0 pounds per batch be retained for 7 kettle the emission the limitation for 4 kettle may be reduced to 30.0 pounds per batch . .Amy this is a summary of the modifications Croda requests to Permit AQM-003/00426 - Renewal 2.
