New Air Quality Regulations for Colorado’s Oil and Gas Industry

June 14, 2021

By: Chad Powell

On April 14, 2021 new air quality regulations became effective for Colorado’s oil and gas industry. The regulations affect pneumatic controllers found at new and existing well production facilities and natural gas compressor stations. These regulatory changes are based on revisions to the Air Quality Control Commission’s directives to consider pneumatic device requirements for greenhouse gas (GHG) reductions as part of a statewide effort. Additionally, the state of Colorado is working towards attainment with the ozone National Ambient Air Quality Standards (NAAQS) for the Denver Metro North Front Range (DMNFR) that was recently re-designated to Serious non-attainment. The Colorado Department of Public Health and Environment (CDPHE) has regulatory authority to enforce these regulations in Colorado.

Non-emitting Controllers

The new regulations include the following changes to well production facilities and natural gas compressor stations:

  • New facilities commencing operation on or after May 1, 2021 are required to install and operate non-emitting controllers;
  • Existing facilities having commenced operations prior to May 1, 2021 must develop plans on a company-wide basis to convert natural gas emitting pneumatic controllers to non-emitting controllers;
    • Alternatively, an operator can choose to plug and abandon existing well production facilities;
    • Operators are required to submit a company-wide plan by September 1, 2021 with updates due in July 2022 and July 2023;
    • Well production facilities must determine the historic liquids production, number of gas-actuated pneumatic controllers, and number of non-emitting controllers for each such facility. The total historic non-emitting facility percent production is the basis for the percentage deadlines for converting to non-emitting controllers.

What This Means for You

Owners and operators should evaluate their current air program and determine how these proposed regulations will impact their operations. Four big efforts include:

  • Identifying the number of gas-actuated pneumatic controllers vs. the number of non-emitting controllers at facilities;
  • Evaluating total historic production for all well facilities and total controller count at natural gas compressor stations;
  • Planning for a phase-out of existing natural gas actuated pneumatic controllers based on the percentages and deadlines required; and
  • Preparing and submitting to CDPHE the company-wide plan.
