Sec. 148.21  Information to be submitted in support of petitions.

    (a) Information submitted in support of Sec. 148.20 must meet the 
following criteria:
    (1) All waste analysis and any new testing performed by the 
petitioner shall be accurate and reproducible and performed in 
accordance with quality assurance standards;
    (2) Estimation techniques shall be appropriate, and EPA-certified 
test protocols shall be used where available and appropriate;
    (3) Predictive models shall have been verified and validated, shall 
be appropriate for the specific site, waste streams, and injection 
conditions of the operation, and shall be calibrated for existing sites 
where sufficient data are available;
    (4) An approved quality assurance and quality control plan shall 
address all aspects of the demonstration;
    (5) Reasonably conservative values shall be used whenever values 
taken from the literature or estimated on the basis of known information 
are used instead of site-specific measurements; and
    (6) An analysis shall be performed to identify and assess aspects of 
the demonstration that contribute significantly to uncertainty. The 
petitioner shall conduct a sensitivity analysis to determine the effect 
that significant uncertainty may contribute to the demonstration. The 
demonstration shall then be based on conservative assumptions identified 
in the analysis.
    (b) Any petitioner under Sec. 148.20(a)(1)(i) shall provide 
sufficient site-specific information to support the demonstration, such 
as:
    (1) Thickness, porosity, permeability and extent of the various 
strata in the injection zone;
    (2) Thickness, porosity, permeability, extent, and continuity of the 
confining zone;
    (3) Hydraulic gradient in the injection zone;
    (4) Hydrostatic pressure in the injection zone; and
    (5) Geochemical conditions of the site.
    (c) In addition to the information in Sec. 148.21(b), any 
petitioner under Sec. 148.20(a)(1)(ii) shall provide sufficient waste-
specific information to ensure reasonably reliant predictions about the 
waste transformation. The petitioner shall provide the information 
necessary to support the demonstration, such as:
    (1) Description of the chemical processes or other means that will 
lead to waste transformation; and

    (2) Results of laboratory experiments verifying the waste 
transformation.
