Q: A pesticide airplane flew over our house at least 20 times at the tip of our trees on July 28. I would like to know why that is legal.
A: In Iowa, aircraft used for aerial application must be registered with the Iowa DOT and hold a valid aircraft registration certification. Additionally, operators must comply with FAA regulations, including obtaining a Part 137 certification for agricultural aircraft, which governs the spraying of pesticides and other chemicals.
Over congested areas, aircraft must fly at least 1,000 feet above the highest obstacle. In non-congested areas, aircraft can operate below 500 feet but must maintain safe distances from people, vessels, vehicles and structures. In addition to aircraft registration and FAA certification, operators must obtain a pesticide license from the Iowa Department of Agriculture and Land Stewardship.
A person in Iowa with concerns about unsafe airplane spraying should contact the Iowa Department of Agriculture and Land Stewardship’s Pesticide Bureau at 515-281-8591. They are responsible for responding to complaints related to pesticide use and safety.
Q: What makes the lake water turn green? Is it really from Round-up and/or hog manure?
A: Lakes turn green mainly due to the presence of excess nutrients, particularly phosphorus and nitrogen. These nutrients stimulate the rapid growth of algae, especially cyanobacteria, commonly known as blue-green algae. The following factors contribute to nutrient overload in lakes:
- Agricultural runoff: Fertilizers used in farming can wash into nearby lakes during rain.
- Wastewater discharge: Nutrients from sewage treatment plants can enter lakes if not properly treated.
- Septic system leaks: Improperly functioning septic systems can leak nutrients into surrounding waters.
- Stormwater runoff: Rain can carry pollutants from urban areas into lakes.
Q: I want to tint the windows on my side-by-side, but I don’t want to get pulled over and fined for them not being done correctly. Do UTVs need to abide by the same laws as cars?
A: That depends. UTVs (Utility Task Vehicles) that are used solely for off-road purposes are not subject to tint regulations. Once a UTV is registered for street use, it must comply with the same tint laws as cars. The front side windows must allow a minimum of 70% light transmission, while there are generally no restrictions on the rear side and rear windows. These regulations are designed to ensure safety and visibility for both drivers and law enforcement during traffic stops. Always check local regulations for any specific requirements.
Q: Are Canada geese really a protected species? How could this be? They are such a nuisance.
A: Yes, Canada geese are federally protected in the United States under the Migratory Bird Treaty Act. This law prohibits harming, capturing or killing Canada geese without specific permits issued by the U.S. Fish and Wildlife Service (USFWS). While Canada geese are protected, there are regulations that allow for limited control measures in certain situations.
Depredation Permits allow property owners to manage geese that become a nuisance. Licensed hunters can also harvest Canada geese during designated seasons, which helps manage local populations. Always consult local wildlife agencies for guidance on managing Canada geese legally.
Q: Now that Iowa’s official speed limit is 60 mph on two-lane highways, why hasn’t the speed changed on Highway 4 headed north out of Panora?
A: Highway 4 between Panora and 200th Road remains 55 mph — NOT 60 mph. The Iowa DOT is in the process of reviewing this road to determine what speed and signage is appropriate. Until the DOT declares otherwise, it is 55 mph.
