(b) Condensate water from processing equipment. <br /> <br />(c) Reject product. <br />(d) Wash down water used in the production areas to <br />clean up equipment. <br />(e) Dust collection water used in scrubbing dust from <br />collected air. <br />(f) Overflow collection points from the brine <br />processing operation. <br />(g) Boiler blowdown, which is water that is purged <br />from a boiler system to control the buildup of <br />dissolved solids. <br />(h) Water softener backwash. <br />(i) Reverse osmosis reject. <br />(j) Make-up water used to make up the difference <br />between the new volumes and required volume of <br />injection fluid. <br />Additional fluid sources may be added only after <br />written approval from the Director. Injection of any <br />hazardous waste as identified under 90 CFR 261.3 is <br />prohibited. The permittee shall demonstrate under the <br />provisions of 90 CFR 262.11 that the fluid sources are <br />not hazardous. This demonstration, including the <br />appropriate TCLP measurements, shall be rerun when any <br />major change of source water occurs. <br />7. Annular Fluid. A pressurized gas or fluid (e.g., COZ, <br />natural gas, air, nitrogen or an inert, immiscible <br />liquid) blanket shall be maintained in the annulus <br />between the tubing system and the outer casing. <br />During normal operations, the annular fluid/mining <br />solution interface must be maintained at a depth that <br />is below the Dissolution Surface. The fluid blanket <br />may assist in controlling the vertical growth of the <br />cavity. In no case shall injection or production be <br />through the annulus between the tubing system and the <br />outer casing. <br />Page 14 of 120 <br />EPA FINAL Area Permit No. CO3870-00000 <br />
