OHV system plans do not contain adequate environmental review. The review process must include public participation. Input from non-motorized recreationists, property owners and other citizens should be considered before designating any OHV trails. The current lack of public input was brought to light when the Cook County Board of Commissioners requested a public meeting with the DNR to discuss concerns of Cook County residents who feel they were excluded from the OHV trail planning process. Air and water quality are damaged from the concentrated effects that unburned gasoline and oil have on fish and wildlife.
Radar runs increase noise levels to a level that disrupts quality visitor experiences.
Snowmobile noise is known to have a negative aesthetic effect on winter visitors who are seeking quiet and solitude. Snowmobile exhaust systems are often modified after production to enhance performance for activities such as radar races, which lead to undesirable noise levels in the vicinity. Appropriate legislation and regulation are required to minimize both user conflicts and environmental damage caused by OHVs. The rule-making process was marked by a high level of citizen input and participation. More than 180 Native American groups and seven federal agencies were consulted.
