For many years, the Sac Metro AQMD has required permits for combustion equipment associated with the oil and gas industry (compressors, dehydrators, flares, etc.). These units can emit significant amounts of regulated pollutants. The Sac Metro AQMD has recently determined that the various non-combustion equipment and operations associated with the oil and gas industry can also be a significant source of VOC emissions in the Sacramento region and thus not exempt from permit requirements. VOCs from these operations can be emitted directly from combustion-type equipment such as compressors and dehydrators, but also from non-combustion equipment such as pneumatic controllers and storage vessels, as well as fugitive emissions (leaks) from components at well sites and compressor stations.

In addition to local permit requirements, these sources may also be subject to federal New Source Performance Standards (40 CFR part 60, subpart KKK, 40 CFR part 60, subpart LLL, and 40 CFR part 60 subpart OOOO), and National Emission Standards for Hazardous Air Pollutants (40 CFR, Part 63, Subpart HHH).

Beginning July 1, 2018, all unpermitted well pads, compressors/engines, glycol dehydration units, and flare/oxidizers will be required to submit complete permit applications for existing equipment and processes.

What Equipment Needs a Permit?

 Individual permits will be required for each of the following:

  • Well Pad-
Include information about the following ancillary equipment as it will be part of the Well Pad permit:
  • Waste Water Tanks
  • Other Tanks
  • Wells
  • Separators
  • Pneumatic Controllers
  • Hydrogen Sulfide Scrubber
  • Compressors and other Internal Combustion Engines rated 50 HP or less
  • Compressors Other Internal Combustion Engines rated greater than 50 HP
  • Glycol Dehydration Units
  • Flare or Thermal Oxidizer
  • Boilers/Heaters greater than or equal to 1 million BTU/hr 

Equipment will be split into three categories:

  • New Equipment: Equipment that has not been installed or configured as of July 1, 2018.

  • Existing Equipment: Any equipment that is not new equipment and is already installed or configured as of July 1, 2018.

  • Modified Equipment: Any equipment that is existing equipment undergoing any physical change, change in method of operation (including change in fuel) after July 1, 2018.

New and modified equipment is subject to District New Source Review (NSR) and CEQA. Operators of new and modified equipment must receive an Authority to Construct prior to commencing construction.

Deadline for Submittal of Permit Applications

Permit applications and permit fees for existing equipment must be received by the District no later than July 1, 2018.

For new and modified equipment, Sac Metro Air District Rule 201 requires any business or person to obtain an Authority to Construct and Permit to Operate before installing or operating new or modified equipment. Following this requirement will enable business owners to make any required design changes early in the planning stage and stay in compliance. Failure to do so may result in civil or criminal penalties, as well as lost time and money in design and/or the purchase of equipment that can't be permitted. We highly recommend you contact the Sac Metro Air District before purchasing or installing any new equipment. Permit applications and permit fees should be submitted together for new or modified equipment.

Permit Fees

Permit fees are different for existing equipment and new equipment.  

Existing Equipment:

For existing equipment that is not currently permitted with the SMAQMD, the initial permit fee will be equivalent to the Permit Renewal Fee column of the appropriate fee schedule under Rule 301, not the Initial Permit Fee column.

Appropriate fee schedule for specific equipment.

New Equipment:

For new equipment, the initial permit fee will be based on the Initial Permit Fee column of the applicable fee schedule under Rule 301

Permit Application Completeness Determination

A complete permit application constitutes the submittal of all applicable permit application forms as described above and submittal of the appropriate application fee.
