Haw. Code R. § 11-268-4 - Treatment surface impoundment exemption
(a) Wastes
which are otherwise prohibited from land disposal under this chapter may be
treated in a surface impoundment or series of impoundments provided that:
(1) Treatment of such wastes occurs in the
impoundments;
(2) The following
conditions are met:
(i) Sampling and testing.
For wastes with treatment standards in subchapter D and/or prohibition levels
in subchapter C or RCRA section 3004(d) (42
U.S.C. 6924) (1984), the residues from
treatment are analyzed, as specified in section 11-268-7 or section 11-268-32,
to determine if they meet the applicable treatment standards or where no
treatment standards have been established for the waste, the applicable
prohibition levels. The sampling method, specified in the waste analysis plan
under section 11-264-13 or 11-265-13, must be designed such that representative
samples of the sludge and the supernatant are tested separately rather than
mixed to form homogeneous samples.
(ii) Removal. The following treatment
residues (including any liquid waste) must be removed at least annually:
residues which do not meet the treatment standards promulgated under subchapter
D; residues which do not meet the prohibition levels established under
subchapter C or imposed by RCRA section 3004(d) (42
U.S.C. 6924) (1984) (where no treatment
standards have been established); residues which are from the treatment of
wastes prohibited from land disposal under subchapter C (where no treatment
standards have been established and no prohibition levels apply); or residues
from managing listed wastes. If the volume of liquid flowing through the
impoundment or series of impoundments annually is greater than the volume of
the impoundment or impoundments, this flow-through constitutes removal of the
supernatant for the purpose of this requirement.
(iii) Subsequent management. Treatment
residues may not be placed in any other surface impoundment for subsequent
management.
(3) The
impoundment meets the design requirements of subsection 11-264-221(c) or
11-265-221(a), regardless that the unit may not be new, expanded, or a
replacement, and be in compliance with applicable ground water monitoring
requirements of subchapter F of chapter 11-264 or chapter 11-265 unless:
(i) Exempted pursuant to subsection
11-264-221(d) or (e), or to subsection 11-265-221(c) or (d); or,
(ii) Upon application by the owner or
operator, the director, after notice and an opportunity to comment, has granted
a waiver of the requirements on the basis that the surface impoundment:
(A) Has at least one liner, for which there
is no evidence that such liner is leaking;
(B) Is located more than one-quarter mile
from an underground source of drinking water; and
(C) Is in compliance with generally
applicable ground water monitoring requirements for facilities with permits;
or,
(iii) Upon
application by the owner or operator, the director, after notice and an
opportunity to comment, has granted a modification to the requirements on the
basis of a demonstration that the surface impoundment is located, designed, and
operated so as to assure that there will be no migration of any hazardous
constituent into ground water or surface water at any future time.
(4) The owner or operator submits
to the director a written certification that the requirements of paragraph
11-268-4(a)(3) have been met. The following certification is required:
"I certify under penalty of law that the requirements of paragraph (a)(3) of section 11-268-4 of the Hawaii Administrative Rules have been met for all surface impoundments being used to treat restricted wastes. I believe that the 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) Evaporation of hazardous
constituents as the principal means of treatment is not considered to be
treatment for purposes of an exemption under this section.
