If the commission finds that a phased permit may be issued, the commission shall establish, as requirements in the first phase of the facility permit, conditions for conducting the field tests or laboratory analyses. These permit conditions shall include design and operating parameters (including the duration of the tests or analyses and, in the case of field tests, the horizontal and vertical dimensions of the treatment zone), monitoring procedures, post-demonstration clean-up activities, and any other conditions which the commission finds may be necessary under 40 Code of Federal Regulations §264.272(c). The commission shall include conditions in the second phase of the facility permit to attempt to meet all requirements pertaining to unit design, construction, operation, and maintenance of land treatment facilities. The commission shall establish these conditions in the second phase of the permit based upon the substantial but incomplete or inconclusive information contained in the Part B application.(1) The first phase of the permit shall be effective as provided in Texas Civil Statutes, Article 6252-13, and the rules of the commission.(2) The second phase of the permit shall be effective as provided in §305. 184 of this title (relating to Permit Amendment).
