  1. NMOCD PIT RULE • Hot Topic #1 • Re-Use of Produced Water, Drilling Fluids, Other Liquid Oilfield Waste • Notice in your handout • Form C-147 also in your handout • No permit (C-147) required for re-use as: • A drilling or completion fluid • Makeup water • Fracturing fluid • Drilling mud

  2. NMOCD PIT RULE • Re-use of Produced Water • No permit (C-147) required for • Delivery to • An SWD • A secondary recovery or pressure maintenance injection facility • Surface waste management facility • Permanent pit • Drill site for re-cycling as drilling, completion or plugging fluid • C-147 approved by the appropriate OCD district office

  3. NMOCD PIT RULE • Hot Topic #2 • 14-digit API numbers • Hot Topic #3 (Reminder) • Hydraulic Fracturing Fluid Disclosure • Required whether or not you report to FracFocus • Due 45 days after completion of the well • Required by 19.15.16.19 NMAC

  4. NMOCD PIT RULE 19.15.17 NMAC Effective June 28, 2013

  5. NMOCD Pit Rule Case No. 14784 and 14785 Order No. R-13506-D This rule covers all pits, closed-loop systems, below-grade tanks and sumps. Facilities under WQCC Discharge Plans are not exempt.

  6. NMOCD Pit Rule • Major Changes 2009 – 2013 • Below-grade tank now defined as > 5 bbl. Capacity • Continuously flowing watercourse defined • Floodplain defined • New concept: “Life-form ratio” (re-vegetation)

  7. More Changes2009 – 2013 • New concept: “Low chloride fluids” • “Measurable” now defined • New concept: “Multi-well fluid management pit” • Definition of “significant watercourse” expanded and made more descriptive • Temporary pits may now be used for multiple wells

  8. Still More Changes • Major Changes 2009 – 2013 • Permit still required for pits, but below-grade tanks are “registered” (district office) • Closed-loop systems require only notification of their use (district office) • Other than site-specific data may now be used to determine groundwater depth (modeling, cathodic well lithology)

  9. Major Changes in the Pit Rule • Major Changes 2009 – 2013 • Time limits for action on a permit now imposed on the NMOCD • If using “low-chloride fluids” (<15,000 mg/L): • A pit is now allowed where groundwater is at least 25 feet below the bottom of the pit • Significant changes in setbacks • Below-grade tanks meeting standards now allowed where groundwater is at least 25 feet deep

  10. Even More Major Changes • Major Changes 2009 – 2013 • A temporary pit (on-lease) or burial trench (on lease) may receive waste from another temporary pit (on-lease) • Soil beneath a BGT or drying pad shall be remediated to 600 mg/kg chlorides • Containments of only untreated fresh water are not temporary pits for the purposes of the rule

  11. GENERAL REQUIREMENTS All pits and below-grade tanks Sumps, closed loop systems

  12. NMOCD Pit Rule • 19.15.17.9 Permit Application and Registration • Form C-144 is to be used to apply to the division for a permit to construct or use a pit or to register a below-grade tank • May be filed by itself or included as an attachment to a permit application for the facility where the pit or below-grade tank will be located

  13. NMOCD Pit Rule Pit construction requires a permit issued by the division. All pits must be lined. (Form C-144) The division may issue a single permit for all pits associated with a single APD. Below-grade tanks installed after June 28, 2013 must be registered with the appropriate division office. (Form C-144) Closed-loop systems and sumps do not require a permit or registration, but the district office must be notified on the APD or C-103, or applicable BLM form of use of a closed-loop system.
