Purpose of the rule or reason for the change:

This rule is proposed to define procedures and regulations designed to prevent and control the spread of aquatic invasive species within the State of Utah.

Summary of the rule or change:

This rule sets the guidelines and regulations designed to prevent and control the spread of Dreissena mussels in Utah. This amendment adds Electric Lake, Utah; Jumbo Reservoir, Colorado; and Tarryall Reservoir, Colorado.

State statutory or constitutional authorization for this rule:

Sections 23-27-401, 23-14-18, and 23-14-19

Anticipated cost or savings to:

the state budget:

The Division of Wildlife Resources (DWR) determines that these amendments do create a cost impact to the state budget or DWR's budget. The 2008 General Legislative Session appropriated $2,500,000 dollars to aid in the implementation costs associated with this rule.

local governments:

This rule does not create any direct cost or savings impact to local governments because they are not directly affected by the rule. Nor are local governments indirectly impacted because the rule does not create a situation requiring services from local governments.

small businesses and persons other than businesses:

This rule may create a cost impact to boat owners and other water enthusiasts in Utah in that if Dreissena Mussels are found in Utah the cost to decontaminate boats and other conveyances will be at the expense of the owner.

Compliance costs for affected persons:

DWR determines that this rule may create a cost impact to individuals who own water vessels and boat in infested waters because they would be required to decontaminate the conveyance.

Comments by the department head on the fiscal impact the rule may have on businesses:

The amendments to this rule do not create an impact on businesses. Michael R. Styler, Executive Director
