High Risk Areas & Conditions for Agriculture Environmental Management

The Minister’s Regulation – Code of Practice for Agricultural Environmental Management (AEMCoP) – takes a risk-based approach where requirements are tailored to environmental risk. The regulation identifies:

  • High risk areas as those with high precipitation, areas over vulnerable aquifers and areas that are phosphorus-affected. An agricultural operation could be in one or more of these areas
  • High risk conditions include strong winds, storm events, high-intensity rainfall, seasonal high-water tables and flooding

Operations in high-risk areas and during high-risk conditions will need to take more protective measures. These are outlined on the regulation requirements page.

Vulnerable Aquifer Recharge & Phosphorus Affected Area Maps

It aims to help agricultural operations understand if they need a nutrient management plan and when they may need it.

Vulnerable aquifer recharge area means land that is located within the boundaries of an area from which surface water may infiltrate the ground to reach an aquifer that, due to the nature of the overlying soil layers, is highly or moderately vulnerable to pollution, or contamination from the land surface, or is at risk of being adversely affected by nitrates.

A phosphorus-affected area is an area of land that drains into surface water bodies which may be adversely affected by high levels of phosphorus.

This interactive map tool shows the geographic high precipitation areas throughout B.C. If an agricultural operation is in a high precipitation area, it will need to take protective measures specific to the high-risk triggers that apply to it. See Part 5 of the AEMCoP for more information.

A high precipitation area is an area that receives 600 mm or more of precipitation between October 1 and April 30.
