The surface treatment only volume has based on a car sets and not a piece qty. The tonnage does not change but the surface treatment only volume should have actually reflected a volume of 676,800
Additionally the Surface treatment only volume was developed based on a mix of 3 parts – Handles, Mirror Scalps & Rockers. This was the assumption during the business case development for this facility. The mix of parts from current customer requirements has changed since the facility was commissioned and now reflects a volume of approx. 1,959,826 parts with a tonnage still not exceeding 408 tons.
Tonnage does not really deviate from the original submission, but part size from a mix change does drive a volume change
Therefore we find it necessary to request a change to reflect this volume change from the original submission
