Received by: NL

RULE ANALYSIS

Purpose of the rule or reason for the change:

The reason for the change is to change wording to refer to minimum water pressure described in Section R309-105-9. (DAR NOTE: The proposed amendment to Section R309-105-9 is under DAR No. 28416 in this issue.)

Summary of the rule or change:

The change makes reference to Section R309-105-9 so that minimum pressures associated with existing systems will not be confused with minimum pressures required for new Public Water Systems designed and constructed after March 1, 2006.

State statutory or constitutional authorization for this rule:

Section 19-4-104

Anticipated cost or savings to:

the state budget:

None--Since this amendment only clarifies this portion of rule and the additional water pressure requirements for new Public Water Systems, it will not require additional personnel or other funds from the state budget.

local governments:

Little to None--Most, if not all, well functioning Public Water Systems operated by local government currently meet or exceed the current minimum water pressure minimums, as well as the proposed additional minimums. The design of new Public Water Systems will only require initial planning concerning storage location and distribution pipeline sizing which should not add significant cost or time.

other persons:

Little to None--Most engineering companies currently look to typical textbook design standards, as well as standards of other agencies such as the American Water Works Association (AWWA), the American Society of Civil Engineers (ASCE), and other nearby states when designing Public Water Systems so there should not be any additional cost or time involved.

Compliance costs for affected persons:

New Public Water Systems designed and constructed after March 1, 2006, should not see any costs over and above that if their system were designed with the typical capacity for anticipated growth and expansion. Some increased cost may be expected if storage tank location for adequate pressure requires additional length of transmission line.

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

The department agrees that the proposed changes to this rule will have little to no detrimental impact on existing water systems nor on new public water systems. Dianne R. Nielson, Executive Director

RULE TEXT

R309. Environmental Quality, Drinking Water.

R309-545. Facility Design and Operation: Drinking Water Storage Tanks.

R309-545-7. Location of Tanks.

(1) Pressure Considerations.

The location of the reservoir and the design of the water system shall be such that the minimum working pressure in the distribution system [under peak day demand conditions, including fire flow, is 20 psi]shall meet the minimum pressures as required in R309-105-9.

(2) Connections.

Tanks shall be located at an elevation where present and anticipated connections can be adequately served. System connections shall not be placed at elevations such that [a ]minimum [of 20 psi]pressures as required in R309-105-9 cannot be continuously maintained.

(3) Sewer Proximity.

Sewers, drains, standing water, and similar sources of possible contamination shall be kept at least 50 horizontal feet from the reservoir.

(4) Standing Surface Water.

The area surrounding a ground-level drinking water storage structure shall be graded in a manner that will prevent surface water from standing within 50 horizontal feet of the structure.

(5) Ability to Isolate.

Drinking water storage structures shall be designed and located so that they can be isolated from the distribution system. Storage structures shall be capable of being drained for cleaning or maintenance without necessitating loss of pressure in the distribution system.

(6) Earthquake and Landslide Risks.

Potential geologic hazards shall be taken into account in selecting a tank location. Earthquake and landslide risks shall be evaluated.

(7) Security.

The site location and design of a drinking water storage reservoir shall take into consideration security issues and potential for vandalism.

KEY: drinking water, storage tanks, access, overflow and drains
