Emissions Inventory reporting is required by Regulation 61-62.1 Section III and condition 4.B.6 contained in Part 4.B of a facility's Title V permit if the permit was issued before 10/09/2007; condition 4.6 contained in Part 4 of a facility's Title V permit if the permit was issued between 10/09/2007 and 10/14/2008; or condition 4.3 contained in Part 4 of a facility's Title V permit if the permit was issued after 10/14/2008.

What Does the Technical Management Section (TMS) Look for in Reporting?

The TMS looks for four basic elements in reporting: timeliness, completeness, accuracy, and compliance status.

Timeliness - Most periodic reports must be postmarked no later than 30 days after the end of the reporting period. TVACC's must be postmarked no later than 45 days after the end of the reporting period.

Completeness - The facility must submit all of the data required by the permit condition, in the correct format.

The following forms were created to assist facilities with reporting required by construction or operating permits. Use of these forms is not mandatory. These forms are intended for guidance purposes only and may not be applicable to all facilities. Some forms require manipulation so that spreadsheets represent materials used at your facility.
