Sec. 148.1  Purpose, scope and applicability.

    (a) This part identifies hazardous wastes that are restricted from 
disposal into Class I hazarous waste injection wells and defines those 
circumstances under which a waste, otherwise prohibited from injection, 
may be injected.
    (b) The requirements of this part apply to owners or operators of 
Class I hazardous waste injection wells used to inject hazardous waste.
    (c) Wastes otherwise prohibited from injection may continue to be 
injected:
    (1) If an extension from the effective date of a prohibition has 
been granted pursuant to Sec. 148.4 with respect to such wastes; or
    (2) If an exemption from a prohibition has been granted in response 
to a petition filed under Sec. 148.20 to allow injection of restricted 
wastes with respect to those wastes and wells covered by the exemption; 
or
    (3) If the waste is generated by a conditionally exempt small 
quantity generator, as defined in Sec. 261.5; or
    (d) Wastes that are hazardous only because they exhibit a hazardous 
characteristic, and which are otherwise prohibited under this part, or 
part 268 of this chapter, are not prohibited if the wastes:
    (1) Are disposed into a nonhazardous or hazardous injection well as 
defined under 40 CFR Sec. 146.6(a); and
    (2) Do not exhibit any prohibited characteristic of hazardous waste 
identified in 40 CFR part 261, subpart C at the point of injection.

              Subpart C--Petition Standards and Procedures



Sec. 148.20  Petitions to allow injection of a waste prohibited under subpart B.

    (a) Any person seeking an exemption from a prohibition under subpart 
B of this part for the injection of a restricted hazardous waste into an 
injection well or wells shall submit a petition to the Director 
demonstrating that, to a reasonable degree of certainty, there will be 
no migration of hazardous constituents from the injection zone for as 
long as the waste remains hazardous. This demonstration requires a 
showing that:
    (1) The hydrogeological and geochemical conditions at the sites and 
the physiochemical nature of the waste stream(s) are such that reliable 
predictions can be made that:
    (i) Fluid movement conditions are such that the injected fluids will 
not migrate within 10,000 years:
    (A) Vertically upward out of the injection zone; or
    (B) Laterally within the injection zone to a point of discharge or 
interface with an Underground Source of

[[Page 675]]

Drinking Water (USDW) as defined in 40 CFR part 146; or
    (ii) Before the injected fluids migrate out of the injection zone or 
to a point of discharge or interface with USDW, the fluid will no longer 
be hazardous because of attenuation, transformation, or immobilization 
of hazardous constituents within the injection zone by hydrolysis, 
chemical interactions or other means; and
    (2) For each well the petition has:
    (i) Demonstrated that the injection well's area of review complies 
with the substantive requirements of Sec. 146.63;
    (ii) Located, identified, and ascertained the condition of all wells 
within the injection well's area of review (as specified in Sec. 146.63) 
that penetrate the injection zone or the confining zone by use of a 
protocol acceptable to the Director that meets the substantive 
requirements of Sec. 146.64;
    (iii) Submitted a corrective action plan that meets the substantive 
requirements of Sec. 146.64, the implementation of which shall become a 
condition of petition approval; and
    (iv) Submitted the results of pressure and radioactive tracer tests 
performed within one year prior to submission of the petition 
demonstrating the mechanical integrity of the well's long string casing, 
injection tube, annular seal, and bottom hole cement. In cases where the 
petition has not been approved or denied within one year after the 
initial demonstration of mechanical integrity, the Director may require 
the owner or operator to perform the tests again and submit the results 
of the new tests.

    Note: The requirements of Sec. 148.20(a)(2) need not be incorporated 
in a permit at the time of petition approval.

    (b) A demonstration under Sec. 148.20(a)(1)(i) shall identify the 
strata within the injection zone which will confine fluid movement above 
the injection interval and include a showing that this strata is free of 
known transmissive faults of fractures and that there is a confining 
zone above the injection zone.
    (c) A demonstration under Sec. 148.20(a)(1)(ii) shall identify the 
strata within the injection zone where waste transformation will be 
accomplished and include a showing that this strata is free of known 
transmissive faults or fractures and that there is a confining zone 
above the injection zone.
    (d) A demonstration may include a showing that:
    (1) Treatment methods, the implementation of which shall become a 
condition of petition approval, will be utilized that reduce the 
toxicity or mobility of the wastes; or
    (2) A monitoring plan, the implementation of which shall become a 
condition of petition approval, will be utilized to enhance confidence 
in one or more aspects of the demonstration.
    (e) Any person who has been granted an exemption pursuant to this 
section may submit a petition for reissuance of the exemption to include 
an additional restricted waste or wastes or to modify any conditions 
placed on the exemption by the Director. The Director shall reissue the 
petition if the petitioner complies with the requirements of paragraphs 
(a), (b) and (c) of this section.
    (f) Any person who has been granted an exemption pursuant to this 
section may submit a petition to modify an exemption to include an 
additional (hazardous) waste or wastes. The Director may grant the 
modification if he determines, to a reasonable degree of certainty, that 
the additional waste or wastes will behave hydraulically and chemically 
in a manner similar to previously included wastes and that it will not 
interfere with the containment capability of the injection zone.



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

[[Page 676]]

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.

    (a) Any petition submitted to the Director pursuant to 
Sec. 148.20(a) shall include the following components:
    (1) An identification of the specific waste or wastes and the 
specific injection well or wells for which the demonstration will be 
made;
    (2) A waste analysis to describe fully the chemical and physical 
characteristics of the subject wastes;
    (3) Such additional information as is required by the Director to 
support the petition under Secs. 148.20 and 148.21; and
    (4) This statement signed by the petitioner or an authorized 
representative:

    I certify under penalty of law that I have personally examined and 
am familiar with the information submitted in this petition and all 
attached documents, and that, based on my inquiry of those individuals 
immediately responsible for obtaining the information, I believe that 
submitted information is true, accurate, and complete. I am aware that 
there are significant penalties for submitting false information, 
including the possibility of fine and imprisonment.

    (b) The Director shall provide public notice and an opportunity for 
public comment in accordance with the procedures in Sec. 124.10 of the 
intent to approve or deny a petition. The final decision on a petition 
will be published in the Federal Register.
    (c) If an exemption is granted it will apply only to the underground 
injection of the specific restricted waste or wastes identified in the 
petition into a Class I hazardous waste injection well or wells 
specifically identified in the petition (unless the exemption is 
modified or reissued pursuant to Sec. 148.20(e) or (f).
    (d) Upon request by any petitioner who obtains an exemption for a 
well under this subpart, the Director shall initiate and reasonably 
expedite the necessary procedures to issue or reissue a permit or 
permits for the hazardous waste well or wells covered by the exemption 
for a term not to exceed ten years.



Sec. 148.23  Review of exemptions granted pursuant to a petition.

    (a) When considering whether to reissue a permit for the operation 
of a Class I hazardous waste injection well, the Director shall review 
any petition filed pursuant to Sec. 148.20 and require a new 
demonstration if information shows that the basis for granting the 
exemption may no longer be valid.

[[Page 677]]

    (b) Whenever the Director determines that the basis for approval of 
a petition may no longer be valid, the Director shall require a new 
demonstration in accordance with Sec. 148.20.
