Department of'Labor - OSHA Dallas Area Office Central Place, Suite 230 1425 W. Pioneer Drive Irving, TX 75061 RE: CSHA #M8099 - No. 123 Dear Mr. Freeman*: The new parting spray, being used in our pipe operations, continues to be satisfactory. We have changed to the spray entirely and continue to have good test results. Our efforts are now on the Green Sand Pipe System. We are at the present time, evaluating the new enclosures and hoods at the coresetter stations. It is still too early in the test to have a good evaluation on these enclosures, but they do show some promise of reducing exposure. We are continuing our efforts to reach our goal of compliance with the Dust Standard in the allotted time. If you have any questions or need any additional information, please do not hesitate to contact us. Sincerely, Charles Kuenemann Safety and Security Manager CK:dir
