312 IAC 29-33-11 - Management and storage of plugging wastes and plugging pits
Authority: IC 14-10-2-4; IC 14-37-3
Affected: IC 14-37
Sec. 11.
(a) The
discharge of fluids from any activity associated with plugging operations to
any surface or ground waters or in a location where it is likely to cause
pollution to any surface or groundwater is prohibited.
(b) When plugging a well, the owner or
operator must provide at least one (1) plugging pit or leak-free, portable
above ground tank into which plugging fluid wastes are deposited.
(c) Where excavated plugging pits are used,
they shall be constructed and maintained to provide a minimum of two (2) feet
of freeboard at all times.
(d) All
excavated plugging pits shall be constructed with a liner using one (1) of the
following methods:
(1) Use of a synthetic
liner meeting the requirements of
312 IAC
29-21-2(b).
(2) A compacted clay liner may be applied to
the bottom and sides of the pit to create an impervious barrier. Construction
of the compacted clay liner shall be in accordance with accepted construction
and design principles designed to prevent any leakage or seepage from the pit.
The clay used to construct the liner may be in situ or mixed with additional
off-site materials, if the on-site clay is inadequate.
(3) Other materials or methods used for liner
construction may be used if authorized by the division director after a
demonstration is made by the owner or operator that such materials or methods
will provide equivalent protection and prevent leakage or seepage of fluids
from the pit.
(e) Prior
to excavating a plugging pit on tillable land, the owner or operator shall
consult with the surface owner to determine the location of any subsurface
drainage tiles that may be present in the area of excavation. Excavation
operations shall be conducted in a manner to avoid damage to subsurface
drainage systems where practical. The owner or operator is responsible to
repair or replace any subsurface drainage tiles that are damaged during pit
construction or backfilling operations.
(f) Plugging pits shall be used only for the
temporary storage of plugging fluid wastes as provided in this rule and shall
not be used for the disposal of other wastes that are not directly resulting
from plugging operations.
