In January 2019, Gov. Michelle Lujan Grisham signed an Executive Order (EO) for New Mexico state agencies to develop strategies and regulations to reduce statewide greenhouse gas emissions. The EO ordered the Energy, Minerals and Natural Resources Department’s Oil Conservation Division (OCD) and New Mexico Environment Department to develop regulations to reduce methane emissions from oil and gas operations.
In April 2021, the OCD amended its statewide regulations to reduce waste (e.g., flaring and venting) of natural gas. The rules are included in the New Mexico Administrative Code Title 19, Chapter 15 Parts 7, 18, 19 27 and 28. The rules will be finalized when published in the New Mexico Register.
The New Mexico Environment Department, in separate rule making, will also regulate methane emissions from oil and natural operations from an air quality perspective.
The following is a summary of the OCD rules for flaring and venting. Consult the OCC rules to determine specific rule requirements. See link for full requirements:Â https://www.emnrd.nm.gov/ocd/occ-info/og-rules-and-forms/
Operations Included
- Drilling operations
- Completion operations
- Oil and gas production equipment and facilities
- Natural gas (midstream) gathering systems
Statewide Natural Gas Capture Requirements
Starting April 1, 2021, operators must meet a statewide annual 98% gas capture rate of natural gas produced by the end of 2026. This is required for each of two reporting areas, one north and one south of the Township 10 North line.
The baseline natural gas capture rate will be based on the operator’s fourth quarter 2021 and first quarter 2022 quarterly reports.
Prohibitions
The rule prohibits the venting and flaring of natural gas that constitutes waste (as defined in 19.15.2 NMAC.
This prohibition includes venting or flaring of natural gas during drilling, completion, or production operations.
Exceptions from the prohibition include emergencies, malfunctions and safety considerations. Also, certain activities are specially exempted from the prohibition.
Operators are generally required to flare gas rather than vent gas – except where flaring is not technically feasible or for safety concerns.
Allowable flaring and venting
Exceptions to flaring and venting prohibitions are included in the rules. Consult the regulations for details.
Allowable flaring and venting are not included in the calculation of the natural gas capture rate.
The exceptions include:
- Emergencies, malfunctions and safety considerations
- Well unloading and clean-up operations that comply with regulatory specified provisions
- Exploratory well production during first 12 months of production meeting certain regulatory provisions.
- Tank gauging or sampling of existing storage tanks.
- Load out of liquids from storage tanks
- Repair and maintenance operations including depressuring equipment
- Normal operation (except if prohibited by law or regulation or required by an air permit) of natural gas pneumatic devices; dehydration and amine units; compressors; valves, flanges and connectors; storage tanks; and pigging of pipelines.
- Bradenhead tests, packer leakage tests and production tests lasting less than 24 hours.
- Commissioning of pipelines, equipment and facilities.
Performance Standards
- Operators have a general duty to maximize natural gas recovery by minimizing venting and flaring.
- Minimize leaks and releases of natural gas.
- Proper design of equipment and control devices (VRUs, flares, enclosed combustors)
- Use of automatic igniter or continuous pilots.
- Use of technology to alert operator that the flare has malfunctioned.
- Automatic gauging of storage tanks that are equipped with a control device (VRU, flare, enclosed combustor.
- Weekly inspect and document the use of audio, visual, olfactory (AVO) monitoring for leaks.
- Use remote or automated leak and release monitoring technology in lieu of AVO inspections – subject to OCD approval.
- Blowdown of gas gathering systems should be controlled by a flare or enclosed combustor.
- Locate flare at least 100 feet from the well or storage tanks.
- Facilities to be designed to minimize waste and to resolve emergencies as quickly and safely as feasible.
Natural gas management plan.
Operators must file a natural gas management plan with each application to drill (APD) for a new or recompleted well. Operators may file a single natural gas management plan for multiple wells. The plan will describe the actions taken to meet the natural gas capture requirements.
Reporting
Reporting to the OCD using the appropriate form is required. Flaring and venting data will be summarized and published on the OCD’s website.
Reporting includes:
- Monthly well and facility reports of flaring and venting for the rule specified categories (e.g., emergency and malfunction releases, routing operations, etc.).
- By February 28 of each year beginning in 2023, operators must submit a report certifying compliance with the natural gas capture requirements.
Note: This reporting is separate from air quality regulatory and/or air permit reporting required by the New Mexico Environment Department. Â https://www.env.nm.gov/general/report-an-environmental-issue-or-incident/
Credits for ALARM Leak Monitoring
Operators using an OCD approved ALARM (advanced leak and repair monitoring) technology for detecting natural gas leaks (that is not required by law or regulation) are eligible to earn a credit (reduction) against the reported natural gas release.
The OCD will publish a list of approved ALARM technology.
For ALARM approved systems, a credit of 40 percent of the volume of gas released during an event may be granted by the OCD. This can be used by operators to meet the 98% flaring/venting reduction goal. The credit would be applied to the annual reporting for the facility.
Measurement or Estimation
Measurement is required for natural gas recovered, beneficially used, vented and flared.
Estimation of natural gas volumes vented and flared is allowed if metering is not practicable provided the method can be independently verified. Use of an annual GOR test data may be allowed for wells not require measuring devices.
Action Items
- Determine your baseline venting and flaring volumes and baseline capture rate.
- Prepare and implement a natural gas management plan. Parts of a plan can include:
- As needed, replace or upgrade pilots and automatic igniters for flares and enclosed combustors.
- Install systems (SyteLink360TM) to alert operators that the flare, enclosed combustor or VRU is not operating and to document uptime.
- Install systems (SyteLink360TM) to alert operators that the storage tank hatches are not closed properly and to document uptime.
- Use automatic tank gauging if the storage tanks are routed to a control device.
- Measure vent gas volumes from storage tanks to determine which tanks can use a vapor recovery (VRT) and/or vapor recovery units (VRU). Install and operate VRTs and VRUs where feasible.
- Install meters to measure gas sent to flares, enclosed combustors and VRUs.
- Conduct leak monitoring and repair leaks found.
- Use tankless facilities to minimize storage tank emissions.
- Setup a system to track and document the volume of natural gas recovered, flared and vented by each rule specified category (e.g., sold, beneficially used, emergency venting and flaring, pneumatic devices, etc.).
Summary and Conclusions
The rule was developed by the OCD to reduce waste of methane and strengthen collection of royalty and severance taxes. Production and midstream operations are affected by the rule. Allowances for flaring and venting of natural gas from emergencies, malfunctions, safety considerations and routine operation of facilities are included in the rule.
The 98% capture rate is expected to be achievable by the oil and gas operators. Operator written plans, reporting, monitoring, recordkeeping and certification of natural gas capture rate are used to ensure compliance.
The New Mexico Environment Department, in separate rule making, will also regulate methane emissions from oil and gas operations. This may include air quality regulations and air permit requirements for methane emission controls.
