Current through Register Vol. 50, No. 9, September 20, 2024
A. E and P Waste Characterization
1. Generators of E and P Waste must be
familiar with the components of the E and P Waste they generate.
2. If not previously characterized, E and P
Waste characterization procedures should be undertaken to determine the
constituents of E and P Waste prior to disposal.
3. At a minimum, E and P Waste should be
tested for the following constituents: pH, TPH, EC, TCLP benzene, SAR, ESP and
the following metals: As, Ba, Cd, Cr, Cu, Pb, Hg, Mo, Ni, Se, Ag and
Zn.
4. E and P Waste should be
re-characterized if the waste generation process changes significantly (e.g.,
process change, chemical additives, etc.).
5. E and P Waste which is to be taken offsite
or has been taken offsite for storage, treatment, or disposal may be required
to be sampled and analyzed in accordance with EPA protocols or Office of
Conservation (OC) approved procedures.
B. The unpermitted or unauthorized onsite or
offsite storage, treatment, disposal or discharge of E and P Waste is
prohibited and is a violation of these rules.
C. Subsurface disposal of salt water is
required and regulated by LAC 43:XIX.401 et seq. The requirements of this
Chapter do not apply to either lease saltwater disposal wells or to community
saltwater disposal wells.
D. The
generator is responsible for the proper handling and transportation of E and P
Waste taken offsite for storage, treatment, or disposal to assure its proper
delivery to an approved commercial facility or transfer station or other
approved storage, treatment or disposal facility. Failure to properly transport
and dispose of E and P Waste shall subject the generator to penalties provided
for in R.S. 30:18. Each shipment must be
documented as required by
§545
E. At the option of the generator, E and P
Waste may be treated and/or disposed at Department of Natural Resources (DNR)
permitted commercial facilities and transfer stations under the provisions of
this Chapter or Department of Environmental Quality (DEQ) permitted facilities
as defined by LAC 33:V and VII which are permitted to receive E and P Waste
which are subject to relevant DEQ regulations. If received, stored, treated
and/or disposed at a DEQ regulated facility, E and P Waste would become the
sole regulatory responsibility of DEQ upon receipt.
F. Requirements for E and P Waste Type 06
(Storage Tank Sludge) and E and P Waste Type 12 (Gas Plant Waste Solids)
1. Generators of Waste Type 06 are hereby
made aware that commercial land treatment facilities must manage such waste in
compliance with the location criteria of
§507. A.3 and the
maximum permissible concentration (MPC) requirements of
§549. C.7.c and d for
total benzene.
2. Waste Types 12 is
not required to be tested for benzene if disposed at commercial facilities that
utilize treatment options other than land treatment (see §547).
3. Prior to shipment and disposal at
commercial land treatment facilities, natural gas plant processing waste solids
(gas plant waste- Waste Type 12) must be analyzed for the chemical compound
benzene (C6H6). Testing must be
performed by a DEQ certified laboratory in accordance with procedures presented
in the Laboratory Manual for the Analysis of E and P Waste
(Department of Natural Resources, August 9, 1988, or latest
revision).
4. Subject to the
requirements of
§507. A.3 and
§549. C.7 a, Waste Type
12 may be disposed at any commercial land treatment facility if test data
indicates the waste is less than or equal to the MPC of 3198 mg/kg total
benzene.
5. If test data indicates
the concentration of total benzene in Waste Type 12 is above 3198 mg/kg (MPC
criteria), the following disposal options are available:
a. dispose of the waste at a permitted
commercial facility that utilizes an E and P Waste treatment or disposal option
other than land treatment;
b. treat
the waste (on-site) to a concentration of total benzene equal to or below 3198
mg/kg prior to off-site shipment to any commercial land treatment
facility;
c. dispose of the E and P
Waste at a commercial land treatment facility that has been approved for the
receipt, storage, treatment and disposal of E and P Waste that exceeds a total
benzene concentration of 3198 mg/kg; or
d. dispose of the E and P Waste at Department
of Environmental Quality (DEQ) permitted facilities as defined by LAC 33:V and
VII, pursuant to the provisions of
§503. E above.
6. If a generator chooses to
dispose of Waste Type 12 at a commercial land treatment facility, the generator
must attach a copy of the laboratory report to the manifest which accompanies
each shipment of the E and P Waste.
7. Commercial land treatment facilities may
not receive, store, treat or dispose of E and P Waste Type 12, gas plant waste
solids, unless the requirements of
§505. B have been
met.
G. Prohibition of
Waste Mixing
1. A mixture of E and P Wastes
containing amounts greater than residual quantities of Waste Type 06 (and
associated wash water) shall be designated as Waste Type 06, and if land
treated, must meet the distance requirements for Waste Type 06 in
§507. A.3
below.
2. Mixing Waste Type 12 with
any other E and P Waste type prior to sampling and shipment to a commercial
land treatment facility or transfer station is strictly prohibited.
3. Any inadvertent or unavoidable mixture of
E and P Wastes containing any quantity of Waste Type 12 (and associated wash
water) must meet the MPC testing criteria of
§549. C.7.a for total
benzene and must meet the distance requirements for Waste Type 12 in
§507. A 3
H. General Reporting Requirements
1. Any spills which occur during the offsite
transportation of E and P Waste shall be reported by phone to the Office of
Conservation, within 24 hours of the spill and the appropriate state and
federal agencies.
2. Operators
(generators) are required to report the discovery of any unauthorized disposal
of E and P Waste by transporters, or any other oilfield contracting
company.
3. Within six months of
the completion of the drilling or workover of any well permitted by the Office
of Conservation, the operator (generator) shall comply with the reporting
requirements of LAC 43:XIX.303 or successor regulations regarding the
disposition of any E and P Wastes.
