What is the permitted distance for drip irrigation when the runoff coefficient (Ra) is greater than 0.1 to water bodies?

The correct permitted distance for drip irrigation when the runoff coefficient is greater than 0.1 to protect water bodies is 75 feet. This regulation is designed to minimize the risk of nutrient and sediment runoff entering nearby water bodies.

When the runoff coefficient exceeds 0.1, it indicates a higher potential for runoff and associated contaminants. Therefore, a buffer zone of 75 feet is required to effectively mitigate this risk. This distance allows for adequate filtration and absorption of excess nutrients and sediment, thereby protecting water quality in adjacent bodies of water.

Understanding these requirements is crucial for maintaining the integrity of water resources, especially in agricultural practices where fertilizer and other chemicals may be used. The specified distance also emphasizes the importance of responsible water management practices to prevent environmental harm.
