For questions 4-6 that are environmental related, I have attached the standard environmental packet information packet. Specific to storm water, the contractor should install BMPs capable of protecting KAFB storm water collection system quality so that sediment and paint does not leave with storm water.

However, in the event that there is other paint (especially yellow) encountered underneath the brown paint, then the work should cease until the paint is tested.
