NSPS OOOO—Standards of Performance for Crude Oil and Natural Gas Production, Transmission and Distribution for which Construction, Modification or Reconstruction Commenced After August 23, 2011, and on or before September 18, 2015 [40 CFR 60, Subpart OOOO] is a new source performance standard that effects new, modified, or reconstructed hydraulically fractured natural gas wells, crude oil storage tanks, pneumatic pumps, and centrifugal and reciprocating compressors. NSPS OOOO (Quad-O) establishes emission standards and compliance schedules for the control of volatile organic compounds (VOCs), which can contribute to ambient ozone (O3) concentrations, and sulfur dioxide (SO2).

NSPS OOOOa—Standards of Performance for Crude Oil and Natural Gas Facilities for which Construction, Modification or Reconstruction Commenced After September 18, 2015 [40 CFR 60, Subpart OOOOa] is a new source performance standard that effects new, modified, or reconstructed facilities and sources in the crude oil and natural gas source category. NSPS OOOOa (Quad-Oa) establishes emission standards and compliance schedules for the control of volatile organic compounds (VOCs), greenhouse gases (GHG), specifically methane. Quad-Oa also effects new, modified, or reconstructed hydraulically fractured natural gas wells, hydraulically fractured oil wells, crude oil storage tanks, pneumatic pumps, and centrifugal and reciprocating compressors and establishes emission standards and compliance schedules for the control of volatile organic compounds (VOCs), which can contribute to ambient ozone (O3) concentrations, and sulfur dioxide (SO2) that occur after September 18, 2015.

EPA—Controlling Air Pollution from the Oil and Natural Gas Industry

For OOOO/OOOOa Reporting:

  • DO NOT email QUAD-O/Oa compliance reports or notifications to the Department or Department Staff — emailed Quad-O/Oa reports WILL NOT BE ACCEPTED. Note that state IT policy may remove your attachments, thus making the email of these reports unreliable.

  • DO NOT include subject sources from other states or those located on Tribal Lands. Reports that contain additional subject sources not under the Department's jurisdiction will not be accepted. The Department CANNOT evaluate sites outside of its jurisdiction.
    • Please note that there are some imported data from NDIC in CERIS-ND that are on tribal lands—DO NOT use these sites, the Department will be doing future data clean up to remove sites that are not within our jurisdiction.

  • You must also submit your required notifications and reports to EPA Region 8, if required by the rule.

  • The Department is looking into a CERIS-ND feature that would allow uploading the Annual Reports via XML or excel where the data would be pulled from the file to populate the form fields; however, this capability is not yet configured in CERIS-ND.

Interim CERIS-ND Bulk User Access Requests (Add/Remove Users from sites)

  • Note: Bulk Users are a one-time add, so any NEW sites made after a user has been added in a bulk user request needs to be added individually, PER SITE AND PER USER.


  • PRO TIP When you make a new SITE in CERIS-ND the person who makes the site has the Role of Administrator under that SITE'S Authorized Users. Make sure that when you make a new SITE that you add all users to that site. CERIS-ND access is PER SITE and PER USER and access is not automatic by company—users must be added manually.. Add User Instructions


  • PRO TIP Designate one person in your company to be responsible for managing users in CERIS-ND, including adding and removing users via Bulk access requests, and checking that all NEW sites have all users added as authorized users.


  • PRO TIP To Invite users, select the site from the drop down in CERIS-ND then Authorized Users> Invite User to Join. Any user who is has the Administrator Role in [SITE]> Authorized Users can add other users to the site without needing to contact the Department. Add User Instructions
