See Enclosures 1 and 2 . When we tried to apply the interpretation that you provided to us dated April 8 1997 we discovered discrepancies in our characterization of the processes performed in Navy Final Finish and Corrosion Control Hangars. Enclosure 3 defines the operations performed in each of the various level hangars. Our questions are 1. What is your definition of a production spray finishing operation 2. How do you characterize the five operational levels of hangars discussed in Enclosure 3 3. What airflow rate criteria is required .
