Current through Register Vol. 50, No. 9, September 20, 2024
A.
Applicability
1. These rules and regulations
shall apply to all applicants, owners and/or operators of non-commercial salt
cavern waste disposal facilities for disposal or proposed for disposal of
E& P waste. However, where indicated, certain criteria found herein will
also apply to commercial facility operators, in addition to the requirements of
LAC 43:XIX.501 et seq.
2. These
rules and regulations do not address creation of a salt cavern, rather, only
the disposal of E&P waste into a salt cavern. Rules governing the
permitting, drilling, constructing, operating, and maintaining of a Class III
brine solution mining well and cavern are codified in applicable sections of
Statewide Order No. 29-N-1 (LAC 43:XVII, Subpart 1) or successor
documents.
3. An applicant, owner
and/or operator of a salt cavern being solution-mined for conversion to E&P
waste disposal should become familiar with these rules and regulations to
assure that the well and salt cavern shall comply with these rules and
regulations.
B.
Prohibition of Unauthorized Disposal of Exploration and Production Waste
1. Construction, conversion and/or operation
of a salt cavern for disposal of E& P waste without obtaining a permit from
the Office of Conservation is a violation of these rules and regulations and
applicable laws of the state of Louisiana.
2. Any salt cavern well or salt cavern
existing before the effective date of these rules must comply with the
requirements of these rules and regulations before converting the existing well
and salt cavern to E& P waste disposal.
C. Prohibition on Movement of Fluids into
Underground Sources of Drinking Water
1. No
authorization by permit shall allow the movement of injected or disposed fluids
into underground sources of drinking water or outside the salt stock. The owner
or operator of the salt cavern waste disposal facility shall have the burden of
showing that this requirement is met.
2. The Office of Conservation may take
emergency action upon receiving information that injected or disposed fluid is
present in or likely to enter an underground source of drinking water or may
present an imminent and substantial endangerment to the environment, or the
health, safety and welfare of the public.
D. Prohibition of Surface Discharges. The
intentional, accidental, or otherwise unauthorized discharge of fluids, wastes,
or process materials into manmade or natural drainage systems or directly into
waters of the state is strictly prohibited.
E. Identification of Underground Sources of
Drinking Water and Exempted Aquifers
1. The
Office of Conservation may identify (by narrative description, illustrations,
maps, or other means) and shall protect as an underground source of drinking
water, except where exempted under
§3103. E.2 all
aquifers or parts of aquifers that meet the definition of an underground source
of drinking water. Even if an aquifer has not been specifically identified by
the Office of Conservation, it is an underground source of drinking water if it
meets the definition.
2. After
notice and opportunity for a public hearing, the Office of Conservation may
identify (by narrative description, illustrations, maps, or other means) and
describe in geographic and/or geometric terms (such as vertical and lateral
limits and gradient) that are clear and definite, all aquifers or parts thereof
that the Office of Conservation proposes to denote as exempted aquifers if they
meet the following criteria:
a. the aquifer
does not currently serve as a source of drinking water; and
b. the aquifer cannot now and shall not in
the future serve as a source of drinking water because:
i. it is mineral, hydrocarbon, or geothermal
energy producing or can be demonstrated to contain minerals or hydrocarbons
that when considering their quantity and location are expected to be
commercially producible;
ii. it is
situated at a depth or location that makes recovery of water for drinking water
purposes economically or technologically impractical;
iii. it is so contaminated that it would be
economically or technologically impractical to render said water fit for human
consumption; or
iv. it is located
in an area subject to severe subsidence or catastrophic collapse; or
c. the total dissolved solids
content of the groundwater is more than 3,000 mg/l and less than 10,000 mg/l
and it is not reasonably expected to supply a public water system.
F. Exceptions/Variances
1. Except where noted in specific provisions
of these rules and regulations, the Office of Conservation may allow, on a
case-by-case basis, exceptions or variances to these rules and regulations. It
shall be the obligation of the applicant, owner, or operator to show that the
requested exception or variance shall not create an increased endangerment to
the environment, or the health, safety and welfare of the public. The
applicant, owner, or operator shall submit a written request to the Office of
Conservation detailing the reason for the requested exception or variance. No
deviation from the requirements of these rules or regulations shall be
undertaken by the applicant, owner, or operator without prior written
authorization from the Office of Conservation.
2. Granting of exceptions or variances to
these rules and regulations shall only be considered upon proper showing by the
applicant, owner, or operator at a public hearing that such exception or
variance is reasonable, justified by the particular circumstances, and
consistent with the intent of these rules and regulations regarding physical
and environmental safety and the prevention of waste. The requester of the
exception or variance shall be responsible for all costs associated with a
public hearing.
G.
Prohibition through Oilfield Site Restoration Fund. Without exception or
variance to these rules and regulations, no solution-mined salt cavern or
associated well shall be used for exploration and production waste disposal if
the well or salt cavern was previously plugged and abandoned by or where site
restoration has occurred pursuant to funding provided through the Oilfield Site
Restoration Fund,
