If the rainfall erosivity factor is 5 or above, what is required of the LRP?

• A. The LRP shall be required to apply for coverage under this order.
• B. The LRP may continue without coverage.
• C. The LRP must suspend construction.
• D. The LRP must obtain a waiver extension.

Answer: (A)

Rainfall erosivity shows how capable a storm is of causing erosion. When this factor is 5 or above, the risk of soil loss and sediment movement is high enough that regulatory oversight requires formal coverage under the permit/order. In this situation, the LRP must apply for coverage to ensure proper stormwater management, erosion control measures, and compliance with the permit. Skipping coverage or delaying it would leave the project noncompliant with mandated controls, and options like suspending construction or seeking a waiver extension aren’t appropriate responses to this threshold. Applying for coverage ensures the project is subject to the necessary protections and monitoring.
