DAR File No.: 31140

RULE ANALYSIS

Purpose of the rule or reason for the change:

The division is proposing changes to the rule to adopt amendments to the building codes approved by the Uniform Building Code Commission after review by various subcommittees. This proposed amendment is filed as a separate rule filing because it is anticipated that the proposed amendment may be controversial and therefore, if it is changed or not implemented, it will not affect the implementation of other proposed amendments in other filings that need to go forward. (DAR NOTE: the other proposed amendments are: to Rule R156-56 under DAR No. 31139; to Rule R156-56 under DAR No. 31141; and to Section R156-56-701 under DAR No. 31142 all in this issue, May 1, 2008, of the Bulletin.)

Summary of the rule or change:

A new amendment regarding Section 604.4.2 is being added with respect to water conservation zones. The proposed amendment will allow a local compliance agency to designate areas where water capacity or water delivery infrastructure is limited and require that additional water saving equipment be placed in buildings in that area. The water saving equipment would include dual flush toilets, low flow showers and low flow lavatory faucets. Proponents of this proposed amendment report that Utah needs to aggressively address its limited water resource. The Governor's report on growth indicates a 30% population increase by 2020 and projects the population will double by 2050. Recent studies indicate conservation of water as the single greatest opportunity to provide for the future. This proposed amendment would allow local compliance agencies to require greater water conservation. Opponents of the proposed amendment believe this requirement has been inadequately studied and the inside use of water by these measures may not be as significant as claimed and the greatest waste of water is not inside a building but in watering lawns and landscapes. They also claim that the low flush toilets often require multiple flushes and therefore may not result in any savings at all.

State statutory or constitutional authorization for this rule:

Section 58-56-1 and Subsections 58-1-106(1)(a), 58-1-202(1)(a), 58-56-4(2), and 58-56-6(2)(a)

Anticipated cost or savings to:

the state budget:

The division has determined that there should be no direct effect on the state budget as a result of this proposed amendment as the amendment applies to local compliance agencies.

local governments:

The proposed amendment would only apply in zones identified by the local compliance agency. The proponents of the amendment estimate it would cost a townhouse approximately $500 more for the water conserving equipment and that cost would increase accordingly as larger structures with more bathrooms are added. The proponents claim the cost of water in the long term may offset the increased cost of the equipment. They also claim that impact fees to create the water delivery infrastructure to new construction may also be lower if they can reduce the water demands per household. Any anticipated cost savings to local governments cannot be determined at this time. The local government proponents claim that this proposed amendment could result in substantial savings of infrastructure needed to deliver water. It is impossible to estimate the savings that could result.

small businesses and persons other than businesses:

Small businesses and persons: The proposed amendment would only apply in zones identified by the local compliance agency. The proponents of the amendment estimate it would cost a townhouse approximately $500 more for the water conserving equipment and that cost would increase accordingly as larger structures with more bathrooms are added. The proponents claim the cost of water in the long term may offset the increased cost of the equipment. They also claim that impact fees to create the water delivery infrastructure to new construction may also be lower if they can reduce the water demands per household. It is impossible for the division to estimate the aggregate impact because it would vary by the number of buildings affected by the proposed amendment and how much the short term costs are offset by long term savings.

Compliance costs for affected persons:

The proposed amendment would only apply in zones identified by the local compliance agency. The proponents of the amendment estimate it would cost a townhouse approximately $500 more for the water conserving equipment and that cost would increase accordingly as larger structures with more bathrooms are added. The proponents claim the cost of water in the long term may offset the increased cost of the equipment. They also claim that impact fees to create the water delivery infrastructure to new construction may also be lower if they can reduce the water demands per household. It is impossible for the division to estimate costs or savings of this proposed amendment because it would vary by the number of buildings affected and how much the short term costs are offset by long term savings.

No fiscal impact to businesses is anticipated beyond those discussed in the rule summary. Francine A. Giani, Executive Director
