April 27, 2015 – Announcement Regarding Crude Oil and Natural Gas Non-Critical Reported Error Messages

Effective April 27, 2015, the Comptroller’s office will eliminate all reported error messages considered as non-critical. This means error messages labeled as non-critical will no longer be displayed on the Crude Oil and Natural Gas Web Inquiry system. By taking this step, it will be an easier process for taxpayers to review and correct all critical errors.
