(ii) Operation of the injection facility is temporarily granted for the two (2) weeks following initial operations to allow for sample analyses to be performed and for the results to be submitted to EPA. (iii) The Permittee shall maintain copies (or originals) of all records relating to the hazardous waste determination and make such records available for inspection. (iv) The Permittee shall perform an additional hazardous waste determination whenever there is a process change or a change in fluid chemical constituents or characteristics. 2. Mechanical Integrity (a) Mechanical Integrity Tests "MITs") (i) Casing/tubing annular pressure internal MIT) A demonstration of the absence of significant leaks in the casing, tubing and/or liner hanger shall be made by performing a pressure test on the annular space between the tubing and long string casing. This test shall be for a minimum of thirty (30) minutes at a pressure equal to or greater than the maximum allowable injection pressure. A well passes the MIT if there is less than a five (5) percent change in pressure over the thirty (30) minute period. A pressure differential of at least 350 pounds per square inch ("psi") between the tubing and annular pressures shall be maintained throughout the MIT. (ii) Continuous pressure monitoring The tubing/casing annulus pressure and injection pressure shall be monitored and recorded continuously to an accuracy within one (1) psi. The average, maximum, and minimum monthly results shall be included in the quarterly report to EPA unless more detailed records are requested by EPA. (iii) Injection profile survey (external MIT) In conjunction with the initial FOT required in Section A paragraph 5(c), a demonstration that the injectate is confined to the proper zone shall be conducted and presented by the Permittee and subsequently approved by EPA. This demonstration shall consist of a radioactive UIC Pen-nit CA10500002 Page 13 of 29 .
