Current through Register Vol. 35, No. 18, September 24, 2024
A.
General specifications. An operator shall maintain and operate a pit or
closed-loop system, below-grade tank or sump in accordance with the following
requirements.
(1) The operator shall operate
and maintain a pit or closed-loop system, below-grade tank or sump to contain
liquids and solids and maintain the integrity of the liner, liner system or
secondary containment system, prevent contamination of fresh water and protect
public health and the environment.
(2) The operator shall recycle, reuse,
reclaim or dispose of all drilling fluids in a manner consistent with division
rules.
(3) The operator shall not
discharge into or store any hazardous waste in a pit, closed-loop system,
below-grade tank or sump.
(4) If a
pit liner's integrity is compromised above the liquid's surface then the
operator shall repair the damage or initiate replacement of the liner within 48
hours of discovery or seek a variance from the appropriate division district
office.
(5) If a pit or below-grade
tank develops a leak, or if any penetration of the pit liner occurs below the
liquid's surface, then the operator shall remove all liquid above the damage or
leak within 48 hours of discovery, notify the appropriate division office
pursuant to 19.15.29 NMAC and repair the damage or replace the pit liner or
below-grade tank as applicable.
(6)
The injection or withdrawal of liquids from a pit shall be accomplished through
a header, diverter or other hardware that prevents damage to the liner by
erosion, fluid jets or impact from installation and removal of hoses or
pipes.
(7) The operator shall
operate and install a pit, below-grade tank or sump to prevent the collection
of surface water run-on.
(8) The
operator shall install, or maintain on site, an oil absorbent boom or other
device to contain an unanticipated release.
B. Temporary pits. An operator shall maintain
and operate a temporary pit in accordance with the following additional
requirements.
(1) Only fluids or mineral
solids generated or used during the drilling, completion or workover process
may be discharged into a temporary pit. The operator shall maintain a temporary
pit free of miscellaneous solid waste or debris. Immediately after cessation of
a drilling or workover operation, the operator shall remove any visible layer
of oil from the surface of a drilling or workover pit.
(2) The operator shall maintain at least two
feet of freeboard for a temporary pit. For temporary extenuating circumstances
an operator may maintain a freeboard of less than two feet. In such
circumstances the operator shall maintain a log describing such circumstances
and make the log available to the division upon request.
(3) The operator shall inspect a temporary
pit containing drilling fluids at least daily while the drilling or workover
rig is on location. Thereafter, the operator shall inspect the temporary pit
weekly so long as liquids remain in the temporary pit. The operator shall
maintain a log of such inspections and make the log available for the
appropriate division district office's review upon request.
(4) The operator shall remove all free
liquids from the surface of a temporary pit within 60 days from the date that
the operator releases the last drilling or workover rig associated with the
relevant pit permit. The operator shall note the date of the drilling or
workover rig's release on form C-105 or C-103 upon well or workover completion.
The appropriate division district office may grant an extension of up to two
months, not to exceed temporary pit life span under Subsection R of 19.15.17.7
NMAC.
(5) The operator shall remove
any liquids from the temporary pit used for cavitation within 48 hours after
completing cavitation. The operator may request and receive additional time to
remove the liquids from the temporary pit used for cavitation if the operator
demonstrates to the appropriate division district office's satisfaction that it
is not feasible to access the location within 48 hours.
C. Permanent pits. An operator shall maintain
and operate a permanent pit in accordance with the following additional
requirements.
(1) The operator shall maintain
at least three feet of freeboard for a permanent pit; the operator shall
permanently mark such level on the permanent pit.
(2) No oil or floating hydrocarbon shall be
present in a permanent pit.
(3) The
operator shall inspect the pit weekly while the pit has fluids and document at
least monthly until the pit is closed. Inspections will include monitoring of
the leak detection system. The operator shall maintain a log of such
inspections and make the log available for the appropriate division district
office's review upon request.
D. Below-grade tanks. An operator shall
maintain and operate a below-grade tank in accordance with the following
additional requirements.
(1) The operator
shall not allow a below-grade tank to overflow or allow surface water run-on to
enter the below-grade tank.
(2) The
operator shall remove any measurable layer of oil from the fluid surface of a
below-grade tank.
(3) The operator
shall inspect the below-grade tank for leakage and damage at least monthly. The
operator shall document the integrity of each tank at least annually and
maintain a written record of the integrity for five years.
(4) The operator shall maintain adequate
freeboard to prevent overtopping of the below-grade tank.
(5) The operator of a below-grade tank who
discovers that the below-grade tank does not demonstrate integrity or that the
below-grade tank develops any of the conditions identified in Paragraph (5) of
Subsection A of 19.15.17.12 NMAC shall repair the damage or close the existing
below-grade tank pursuant to the closure requirements of 19.15.17.13

below-grade tank who equips or retrofits the existing tank to comply with
Paragraphs (1) through (4) of Subsection I of 19.15.17.11 NMAC shall visually
inspect the area beneath the below-grade tank during the retrofit and document
any areas that are wet, discolored or showing other evidence of a release on
