Virginia’s Department of Environmental Quality (DEQ) employs a Risk Based Inspection Strategy (RBIS) to target facilities for inspection that may not typically be targeted based on standard recommended frequencies provided by The Environmental Protection Agency's (EPA) Compliance Monitoring Strategy (CMS).  Based on the ongoing restrictions to resources, RBIS offers additional flexibility for inspection targeting, as well as an additional foundation (e.g., compliance history) for targeting beyond only a source’s potential for air emissions.  This focus on various source types and categories allows VA DEQ to maintain a sufficient field presence and a strong air compliance program, and at the same time reduce the number of inspections performed at sources that may not pose risk beyond what they may be permitted to emit.

The goal of this measure is to factor in the emphasis ("weighting") on inspection targeting when calculating the efficiency, ultimately providing a value that compares the effort of air compliance staff (i.e., “Weighted Inspections”) to the amount of air compliance resources (i.e., “Inspectors”).  Improved efficiency can be indicated by an increase in this ratio (Weighted Inspections per Inspector).
