sodium carbonate fluids associated with the production of soda ash at their Parachute, Colorado facility. The sodium carbonate fluids are being produced as a result of the in-situ mining of Nahcolite {1Qa}IC03) in the Pic.eance Creek Basin at the Yankee Gulch Sodium Lease. This fluid is transported to the Parachute processing facility by buried pipeline where the sodium carbonate is extracted and processed into soda ash and sodium bicarbonate. Much of the remaining barren fluid is transposed back to the mine site for reinjection into the solution mine ca+~ities, but a portion of the fluid containing impurities is removed during the processing. This 17uid is presently placed in lined and netted surface impoundments. American Soda proposes to utilize this injection well, the Getty #1-7LW, for the disposal of the reject fluid presently going to the impoundments located at the facility. This Permit is for the conversion and operation of an existing Class II (oil and gas related wantes) salt r+~ater injection well as aClass INon-Hazardous well for the disposal of partially saturated to saturated sodium carbonate fluids into the Cozzette and Corcoran Sandstones at a depth of approximately 3,900 feet to 4,270 feet. The waste brine will be transposed by truck from the soda ash facility to the well site and will be stored in on-site tanks prior to injection. Only sodium carbonate brine waste from the soda ash facility ++~ill be accepted for disposal. No onsite industrial ++astes or so)vents generated at the soda asb plant or any offsite facility .gill be accepted for disposal. The average injection pressure is anticipated to be 800 pounds per square inch gauge (psig) with average injection temperatures between 40°F and 80°F. The maximum injection pressure will be limited to 930 pstg. The data submitted with the application from this and other nearby well indicates that the Cozzette and Corocoran sandstones in the vicinity of the Getty No. 1-7LW are not underground sources of drinking water (USDWs). EPA has made a preliminary determination that al] USDWs proximate to the disposal well will be protected. Therefore, the EPA is hereby serving notice of intent to issue a Permit to American Soda, LLP. for the proposed underground injection activities. PUBL]C COM)\7ENTS Al] data submitted by the applicant, as well as the Draft Permit prepared by EPA, are contained in the administrative record for the American Soda, LLP. Getty No. ] -7L.
