Purpose of the rule or reason for the change:

Four definitions were added to support the concurrent changes related to biological water quality assessment criteria at Section R317-2-7. The numbering for the individual definitions was deleted to avoid having to change references throughout the water quality rules when a definition is added or deleted.

Summary of the rule or change:

Definitions were added for biological assessment, biological criteria, human-induced stressor, and use attainability analysis. The numbers for each definition in the section were deleted.

State statutory or constitutional authorization for this rule:

  • Section 19-5-105
  • Federal Clean Water Act Chapter 26 Sec. 1251, 1311
  • Section 19-5-110

Anticipated cost or savings to:

the state budget:

No impact to state budget is anticipated. The proposed amendments add four definitions that do not add any requirements or cause actions that would affect the state budget.

local governments:

No impact to local government is anticipated. The proposed amendments add four definitions that do not add any requirements or cause actions that would affect local governments.

small businesses:

No impacts to small businesses are anticipated. The proposed amendments add four definitions that do not add any requirements or cause actions that would affect small businesses.

No impacts to other persons are anticipated. The proposed amendments add four definitions that do not add any requirements or cause actions that would affect other persons.

Compliance costs for affected persons:

The proposed amendments add four definitions that do not add any requirements or cause actions that would affect compliance costs for affected persons.

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

Four definitions were added to support the concurrent changes related to biological water quality assessment criteria at Section R317-2-7. The proposed amendments do not add any requirements or cause actions that would have a fiscal impact on businesses.
