New Mexico Administrative Code › Title 19 - NATURAL RESOURCES AND WILDLIFE › Chapter 15 - OIL AND GAS › Part 34 - PRODUCED WATER, DRILLING FLUIDS AND LIQUID OIL FIELD WASTE › Section 19.15.34.12 - DESIGN AND CONSTRUCTION SPECIFICATIONS FOR A RECYCLING CONTAINMENT

Current through Register Vol. 35, No. 13, July 16, 2024
A. An operator
				shall design and construct a recycling containment in accordance with the
				following specifications.
(1) The operator
				shall design and construct a recycling containment to ensure the confinement of
				produced water, to prevent releases and to prevent overtopping due to wave
				action or rainfall.
(2) A recycling
				containment shall have a properly constructed foundation and interior slopes
				consisting of a firm, unyielding base, smooth and free of rocks, debris, sharp
				edges or irregularities to prevent the liner's rupture or tear. Geotextile is
				required under the liner when needed to reduce localized stress-strain or
				protuberances that otherwise may compromise the liner's integrity. The operator
				shall construct the containment in a levee with an inside grade no steeper than
				two horizontal feet to one vertical foot (2H:1V). The levee shall have an
				outside grade no steeper than three horizontal feet to one vertical foot
				(3H:1V). The top of the levee shall be wide enough to install an anchor trench
				and provide adequate room for inspection and maintenance.
(3) Each recycling containment shall
				incorporate, at a minimum, a primary (upper) liner and a secondary (lower)
				liner with a leak detection system appropriate to the site's conditions. The
				edges of all liners shall be anchored in the bottom of a compacted earth-filled
				trench. The anchor trench shall be at least 18 inches deep.
(4) All primary (upper) liners in a recycling
				containment shall be geomembrane liners composed of an impervious, synthetic
				material that is resistant to ultraviolet light, petroleum hydrocarbons, salts
				and acidic and alkaline solutions. All primary liners shall be 30-mil flexible
				PVC, 45-mil LLDPE string reinforced or 60-mil HDPE liners. Secondary liners
				shall be 30-mil LLDPE string reinforced or equivalent with a hydraulic
				conductivity no greater than 1 x 10-9 cm/sec. Liner compatibility shall meet or
				exceed the EPA SW-846 method 9090A or subsequent relevant
				publications.
(5) The operator of a
				recycling containment shall minimize liner seams and orient them up and down,
				not across, a slope of the levee. Factory welded seams shall be used where
				possible. The operator shall ensure field seams in geosynthetic material are
				thermally seamed. Prior to field seaming, the operator shall overlap liners
				four to six inches. The operator shall minimize the number of field seams and
				corners and irregularly shaped areas. There shall be no horizontal seams within
				five feet of the slope's toe. Qualified personnel shall perform field welding
				and testing.
(6) At a point of
				discharge into or suction from the recycling containment, the operator shall
				insure that the liner is protected from excessive hydrostatic force or
				mechanical damage. External discharge or suction lines shall not penetrate the
				liner.
(7) The operator of a
				recycling containment shall place a leak detection system between the upper and
				lower geomembrane liners that shall consist of 200-mil geonet or two feet of
				compacted soil with a saturated hydraulic conductivity of 1 x 10-5 cm/sec or
				greater to facilitate drainage. The leak detection system shall consist of a
				properly designed drainage and collection and removal system placed above the
				lower geomembrane liner in depressions and sloped to facilitate the earliest
				possible leak detection.
(8) The
				operator of a recycling containment shall design the containment to prevent
				run-on of surface water. The containment shall be surrounded by a berm, ditch
				or other diversion to prevent run-on of surface water.
