Introduction
The premises map is the foundation for your enhanced biosecurity plan. This map serves to identify areas on your farm that are critical for biosecurity and indicates where critical activities take place what access and activities are taking place at locations throughout your farm. Accurately identifying these critical areas on the premises map and incorporating them into the written descriptions in your plan and Standard Operating Procedures for your farm will assist regulators in understanding where, who, what and how activities are being performed to meet enhanced biosecurity activities. The premises map starts with defining the Perimeter Buffer Area and Perimeter Buffer Area (PBA) Perimeter.
This module will guide you through:
- Defining and establishing the PBA and PBA Perimeter
- An example PBA Perimeter description
- Stations and movements at the PBA Perimeter

PBA) is a functional zone that is comprised of the essential structures and high traffic areas involved in the daily function of the premises. The PBA must have a distinguishable perimeter and typically includes, but is not be limited to, such things as feed storage, manure storage, equipment storage, medical supplies, generators, pump rooms, etc. The PBA is considered less clean than the area inside the LOS, but cleaner than the areas outside the PBA.

Enhanced Biosecurity Plan Requirements:
-
The PBA Perimeter must consist of a physical barrier that restricts access to the PBA through the designated PBA Access Point.
-
The PBA Perimeter and Access Points must be clearly labeled on premises maps.
