March 5, 1980 Applicability of the Prevention of Significant Deterioration (PSD) Regulations to the Baltimore Gas and Electric Company's (BG&E) Brandon Shores Station 6.7

A baseline date for a PSD area is established any day after August 7, 1977 that the first permit application by a proposed major source or modification is filed.

Under a fuel switch the extent to which increased emissions are counted toward the consumption of the applicable PSD increment are modeled as the difference between the maximum air quality impact allowed under the SIP on the baseline date and the maximum air quality impact allowed under the SIP at the time the source begins operation.

The regulatory framework for assessing the extent of a source's PSD increment consumption, if a source has been "grandfathered" depends on the next PSD applicant in the area or if the permitting authority conducts a periodic increment assessment first.
