Applicability criteria and permitting process
The applicability criteria for the Prevention of Significant Deterioration (PSD) program primarily focus on industrial projects that may significantly impact air quality in attainment areas. Typically, new major sources or major modifications to existing sources must undergo review if they have the potential to increase emissions beyond certain thresholds. These thresholds are specified in the regulations and vary depending on the pollution source and pollutant type.
The permitting process begins with a detailed Permit Application submitted to the relevant State or Federal agency. Applicants must demonstrate that the proposed project adheres to all applicable air quality standards, including PSD thresholds. This involves conducting air quality modeling to assess potential impacts and identifying control technologies to minimize emissions. If the project exceeds applicable thresholds, the agency issues a PSD permit, which incorporates specific emission limitations and best available control technology requirements.
Throughout the process, agencies evaluate whether the new or modified source will cause an increase in pollutant levels that could deteriorate air quality beyond the baseline conditions. This ensures that only projects satisfying the criteria proceed, maintaining the integrity of air quality standards while allowing necessary industrial development.
