Under the Pit Design and Construction Information section, the "Calculated Working Volume" of the drill cuttings trench has been converted from cubic yards (7,200 cy) to barrels (~34,624 bbls). Similarly, the daily flow rate has been estimated / converted from cubic yards to barrels. Also, the "Operational Lifespan, per manufacturer's specs (years) is a required value to complete this Form 15: however, it is not applicable to an earthen pit where there are no primary or secondary liners. Therefore, a default value of 1000 years was used. 403136241 403136241 PIT PERMIT SUBMITTED 403136241.pdf 403136241 403136387 OTHER RG 41-18 Form 2A 402342785_approved (1).pdf 431934 403136241 403136395 DESIGN: PLAN AND CROSS SECTION RG 41-18 402398674.pdf 741233 403136241 403136442 SENSITIVE AREA DETERMINATION Sensitive Area Determination RG 41-18 402398687.pdf 177021 403136241 403136444 OPERATIONS PLAN RG 41-18 facility layout dwg 402399285.pdf 585766 403136241 403136468 TOPOGRAPHIC MAP RG 41-18 Hydro-topo map 402398677.pdf 249856 403136241 402342785 02A Form 2A Thread was being aborted.
