RULE ANALYSIS

Purpose of the rule or reason for the change:

The proposed amendments are being made to bring all the R317 rules into conformity with the changing from "Total Coliform" or "Fecal Coliform" bacteria to "E. coli" in Rule R317-2 entitled Standards of Quality for Waters of the State. (DAR NOTE: The proposed amendment to Rule R317-2 was published in the January 1, 2005, issue of the Utah State Bulletin under DAR No. 27593.)

 

Summary of the rule or change:

"Total Coliform" or "Fecal Coliform" bacteria and their associated numeric criteria are changed to (or augmented with) "E. coli" and its associated numeric criteria.

 

State statutory or constitutional authorization for this rule:

Section 19-5-104

 

Anticipated cost or savings to:

the state budget:

There are no anticipated costs or savings to state budget. The proposed amendments change one method of measuring bacteria for another. The costs of the current and proposed analysis methods are substantially the same.

 

local governments:

The proposed amendments change one method of measuring bacteria for another. The costs of the current and proposed analysis methods are substantially the same. There are no anticipated costs or savings to local government.

 

other persons:

The proposed amendments change one method of measuring bacteria for another. The costs of the current and proposed analysis methods are substantially the same. There are no anticipated costs or savings to other persons.

 

Compliance costs for affected persons:

There are no anticipated additional compliance costs for affected persons. The proposed amendments change one method of measuring bacteria for another. The costs of the current and proposed analysis methods are substantially the same.

 

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

There are no anticipated additional compliance costs for affected businesses. The proposed amendments change one method of measuring bacteria for another. The costs of the current and proposed analysis methods are substantially the same.
