Oregon Pesticide Practice Test

What agency enforces the rules for back-siphon/anti-siphon prevention during chemigation?

1. Oregon Department of Agriculture (ODA)

2. Oregon Water Resources Department (OWRD)

3. Oregon Occupational Safety and Health Administration (OR-OSHA)

4. Oregon Department of Environmental Quality (DEQ)

The correct answer is: Oregon Water Resources Department (OWRD)

The correct answer is the Oregon Water Resources Department (OWRD) because this agency is responsible for managing and protecting the state’s water resources. This includes enforcing regulations that prevent contamination of water supplies during agronomic practices such as chemigation, where chemicals are applied through irrigation systems. Back-siphon and anti-siphon measures are critical to prevent potential backflow of contaminated water into clean water sources, which is an essential aspect of ensuring public health and environmental safety. The other agencies listed have different responsibilities. The Oregon Department of Agriculture (ODA) primarily oversees agricultural practices and pesticide regulations, but its focus is more on the application and use of pesticides rather than specific irrigation practices. Oregon Occupational Safety and Health Administration (OR-OSHA) deals with workplace safety regulations, including those in agricultural settings, but does not regulate water resource management. The Oregon Department of Environmental Quality (DEQ) focuses on protecting the environment and public health by regulating pollutants and hazardous substances, but it is not the primary agency for water management and chemigation rules.
