What is a Plant-wide Applicability Limit (PAL)?
A PAL is an emission limitation expressed in tons per year, for a pollutant at a major stationary source, that is enforceable as a practical matter and established source-wide in accordance with C.F. R. 52.21 (aa)(1)-(15). Prior to the adoption of this PAL provision, the department had a regulation known as a Pre-Approved Limit PAL specific to diesel engines and gasoline distribution facilities categorized as bulk plants. To avoid confusion, these have been renamed Pre-approved Emission Limits (PAELs).
