Wells used for the disposal of produced water, specific common oilfield waste streams, and waste streams meeting specific criteria.
Saline fluids as obtained from oilfield waste processing facilities, oilfield tank washing operations, oil spill containment and recovery, or similar operations; Boiler blowdown water Liquid fraction of drilling muds, including kc1 muds, but excluding diesel inverts (in accordance with section 2.0); Aqueous liquid fractions of spent sweetening agents - neutralized (cansweet 200, 300, 300sx, 500, sulphacheck, sulfa-scrub); Amine filter backwash (eg. Mea, dba, mdea); Sulphur block run-off water – neutralized; Inorganic salts used in heat exchange medium (eg. Sodium/potassium nitrates/nitrites), properly solubilized using an existing aqueous waste stream; Waste fluids from drilling operations (i.E. Used in or originating from the wellbore); Spent workover or stimulation fluids (after neutralization and/or processing to recover hydrocarbons); Glycol solutions as obtained from dehydration operations; Methanol or hydro-test solutions; Acidic or alkaline solutions (neutralized) with heavy metal concentrations at or below the levels given in schedule 1; Gas scrubber or absorption tower bottom liquids (neutralized) with heavy metal concentrations at or below the levels of schedule 1; Washing waste water (ie. Detergent or soap wastes); Corrosion inhibitor solutions with heavy metal concentrations at or below schedule 1levels; Oxygen scavenger solutions with heavy metal concentrations at or below schedule 1 levels.
