authorized wells in the field (and any future wells) not presently proposed for pressure increases <br />will continue to be limited to the 700 psi injection pressure authorized by the Permit. <br />With receipt of your step pressure tests and attachments, the Yankee Gulch Project Area <br />Permit (CO3858-00000) is being modified to reflect the increased injection pressure as <br />requested. EPA hereby modifies the following conditions of the previously modified Area <br />Permit. <br />Existing version of Permit: <br />PART II. C.4. <br />4. Injection Pressure Limitation. (Paragraph 1.} Based on the results from the test <br />mining, a maximum iniectio~ressure of 700 psie is approved for all wells within <br />the EPA Area Permit No. CO 3858-00000, until such time as the operator <br />demonstrates otherwise. The operator, based on the results of an injection <br />pressure test using fluid normally injected to determine the instantaneous shut in <br />pressure (IS1P) and formation breakdown pressure, may request a change in the <br />maximum injection pressure from the Director. <br />Based on the step pressure test results a maximum allowable injection pressure of 800 <br />P~ is approved by the Director for the sixteen (16) wells listed below: <br />We1120-30 EPA Permit No, CO3859-04557 Tested (9/26/01)-Initial Test <br />2.
