Question Information
Number   Question Response   Response Text  
1 Will you maintain quantities of mud and mud material (including weight materials and additives) sufficient to raise the entire system mud weight 1/2 ppg or more? Y  
2 If hydrocarbon-based or synthetic-based drilling fluids were used, is the drilling rig outfitted for zero discharge, and will zero discharge procedures be followed? N/A  
3 If drilling the shallow casings strings riserless, will you maintain kill weight mud on the rig and monitor the wellbore with an ROV to ensure that it is not flowing? N/A  
4 If requesting a waiver of the conductor casing, have you submitted a log to government agency G&G that is with in 500 feet of the proposed bottom hole location for the proposed surface casing point? N/A  
5 Will the proposed operation be covered by an EPA Discharge Permit? (please provide permit number in comments for this question) Y GMG 290129
6 Will all wells in the well bay and related production equipment be shut-in when moving on to or off of an offshore platform, or from well to well on the platform? If not, please explain. Y  
7 Is the calculated daily volume possible from an uncontrolled blowout of this well greater than the daily volume included in the worst case discharge scenario in the approved oil spill response plan? N  
8 Has the drilling rig been approved for the use of digital BOP testing? If yes, which version? N/A
