SECTION 240.530 COMPLETION FLUID AND COMPLETION FLUID WASTE HANDLING AND STORAGE
Section 240.530 Completion Fluid and Completion Fluid Waste Handling and Storage
a) Completion Fluid Handling and Storage Prior to Use
If completion fluids are temporarily stored at the well site prior to use in completion activities, the fluids shall be stored in a lined completion pit or leak free above ground container.
b) Completion Fluid Waste Handling and Storage
Completion fluid wastes generated from the well during completion activities shall be collected at the well site in a completion pit or leak free above ground container. A pit used for this purpose need not be lined.
c) Completion and Workover Pits
1) Pits used for completion fluids and completion fluid wastes shall be constructed with sufficient capacity to contain the fluids within the pits, and maintained in a manner that reasonably prevents against overflow during completion or workover activities and prior to commencing pit restoration in accordance with Section 240.540 of this Part. Discharge of completion fluids and completion fluid wastes from the pits into any surface water or water drainage way is prohibited.
2) The sediment pit or the drilling fluid circulation pit used during drilling operations may be used for the collection of completion fluid wastes during completion activities. If either pit is used as a completion pit, drill cuttings and drilling fluids shall first be removed and a dike constructed to prevent completion fluid wastes from entering the other pit.
3) Completion or workover pits used to store completion fluids prior to use in the well shall be lined with a liner at least 20 mils in thickness.
4) Completion or workover pits shall be used only for the temporary storage of completion fluids and completion fluid wastes in accordance with the requirements of this subsection, and shall not be used for the disposal of general oilfield wastes.
