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.

Overview

As part of the air permitting process, facilities in South Carolina are required to demonstrate that the emissions coming from their sources will not cause the violation of any applicable South Carolina air pollution control regulations or standards. It is a required part of many air construction permits (including all Prevention of Significant Deterioration (PSD) construction permits) and some Title V, conditional major, and state operating permits and renewals.

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.
