Administration: General Responsibilities of Public Water Systems
NOTICE OF PROPOSED RULE
DAR File No.: 29369
Filed: 12/26/2006, 01:06
Received by: NL
Purpose of the rule or reason for the change:
This rule change is to address the changes required by the federal Long Term 1 and 2 Surface Water Treatment rules (LT1 and LT2), the Stage 2 Disinfection Byproducts rule (Stage 2), and the Improvement Priority rule (IPS). There are a total of eight amendments that address these rules (Rules R309-105, R309-110, R309-200, R309-210, R309-215, R309-220, R309-225, and R309-150). This rule adoption is necessary to maintain primacy.
Summary of the rule or change:
Changes to the reporting and recordkeeping sections to incorporate the requirements of LT1, LT2, and Stage 2, and rule reference changes from Rule R309-150 to Rule R309-400.
State statutory or constitutional authorization for this rule:
Sections 19-4-104, and 40 CFR 141 Subparts T, W, L, U, and V
Anticipated cost or savings to:
the state budget:
Costs for the state budget, local governments, and other persons will be based on an aggregate for the changes in Rules R309-105, R309-110, R309-200, R309-210, R309-215, R309-220, R309-225 and R309-150. The Environmental Protection Agency (EPA) estimates state costs to be $9,260,000 annually. Using the percentage of Utah systems versus the national total (approximately 1%), Utah's annual impact is approximately $92,600.
For this rule change, aggregate costs will vary by water system size, sources utilized, and type of treatment. EPA estimates the total national annual cost at $143,407,000. Again using the percentage of Utah systems versus the national total, Utah's systems' impact is estimated to be $1,434,070 annually.
Other persons that own and operate a public water system may have the same cost impact as listed under "local government" above. Costs to consumers will vary depending upon the water system size. EPA estimates the cost to vary from $1 to $301 per household per year.
Compliance costs for affected persons:
Aggregate compliance costs for the rule change will vary depending upon the water system size, type of source, and type of treatment. EPA estimates the cost to vary from $1 to $301 per household per year. The highest costs are associated with the very small public water systems where there are very few connections to spread the cost of monitoring and treatment across. Persons that own and operate a public water system may have the same cost impact as listed under "local government" above.
Comments by the department head on the fiscal impact the rule may have on businesses:
The Department of Environmental Quality agrees with the comments in the cost and compliance summaries above. Dianne R. Nielson, Executive Director

R309-105-6. Construction of Public Drinking Water Facilities.
The following requirements pertain to the construction of public water systems.
(1) Approval of Engineering Plans and Specifications
(a) Complete plans and specifications for all public drinking water projects, as described in R309-500-5, shall be approved in writing by the Executive Secretary prior to the commencement of construction. A 30-day review time should be assumed.
(b) Appropriate engineering reports, supporting information and master plans may also be required by the Executive Secretary as needed to evaluate the proposed project. A certificate of convenience and necessity or an exemption therefrom, issued by the Public Service Commission, shall be filed with the Executive Secretary prior to approval of any plans or specifications for projects described in R309-105-6(3)(a).
(2) Acceptable Design and Construction Methods
(a) The design
and construction methods of all public drinking water facilities shall conform
to the applicable standards contained in [
R309-204 and ]R309-500 through
R309-550 of these rules. The Executive
Secretary may require modifications to plans and specifications before approval
(b) There may be
times in which the requirements of the applicable standards contained in [
and ]R309-500 through R309-550 are not appropriate. Thus, the Executive Secretary may grant an
"exception" to portions of these standards if it can be shown that
the granting of such an exception will not jeopardize the public health.
or new treatment techniques may be developed which are not specifically
addressed by the applicable standards contained in [
R309-204 and ]R309-500
through R309-550. These treatment
techniques may be accepted by the Executive Secretary if it can be shown that:
(i) They will result in a finished water meeting the requirements of R309-200 of these regulations.
(ii) The technique will produce finished water which will protect public health to the same extent provided by comparable treatment processes outlined in the applicable standards contained in R309-204 and R309-500 through R309-550.
(iii) The technique is as reliable as any comparable treatment process governed by the applicable standards contained in R309-204 and R309-500 through R309-550.
(3) Description of "Public Drinking Water Project"
Refer to R309-500-5 for the description of a public drinking water project and R309-500-6 for required items to be submitted for plan approval.
(4) Specifications for the drilling of a public water supply well may be prepared and submitted by a licensed well driller holding a current Utah Well Driller's Permit if authorized by the Executive Secretary.
(5) Drawing Quality and Size
Drawings which are submitted shall be compatible with Division of Drinking Water Document storage. Drawings which are illegible or of unusual size will not be accepted for review. Drawing size shall not exceed 30" x 42" nor be less than 8-1/2" x 11".
(6) Requirements After Approval of Plans for Construction
After the approval of plans for construction, and prior to operation of any facilities dealing with drinking water, the items required by R309-500-9 shall be submitted and an operating permit received.
R309-105-8. Existing Water System Facilities.
(1) All public water systems shall deliver water meeting the applicable requirements of R309-200 of these rules.
facilities shall be brought into compliance with [
R309-204 and ]R309-500
through R309-550 or shall be reliably capable of delivering water meeting the
requirements of R309-200.
(3) In situations where a water system is providing water of unsatisfactory quality, or when the quality of the water or the public health is threatened by poor physical facilities, the water system management shall solve the problem(s).
R309-105-10. Operation and Maintenance Procedures.
All routine operation and maintenance of public water supplies shall be carried out with due regard for public health and safety. The following sections describe procedures which shall be used in carrying out some common operation and maintenance procedures.
(1) Chemical Addition
(a) Water system operators shall determine that all chemicals added to water intended for human consumption are suitable for potable water use and comply with ANSI/NSF Standard 60.
(b) No chemicals or other substances shall be added to public water supplies unless the chemical addition facilities and chemical type have been reviewed and approved by the Division of Drinking Water.
(c) Chlorine, when used in the distribution system, shall be added in sufficient quantity to achieve either "breakpoint" and yield a detectable free chlorine residual or a detectable combined chlorine residual in the distribution system at points to be determined by the Executive Secretary. Residual checks shall be taken daily by the operator of any system using disinfectants. The Executive Secretary may, however, reduce the frequency of residual checks if he determines that this would be an unwarranted hardship on the water system operator and, furthermore, the disinfection equipment has a verified record of reliable operation. Suppliers, when checking for residuals, shall use test kits and methods which meet the requirements of the U.S. EPA. The "DPD" test method is recommended for free chlorine residuals. Information on the suppliers of this equipment is available from the Division of Drinking Water.
(2) New and Repaired Mains
(a) All new water mains shall meet the requirements of R309-550-6 with regard to materials of construction. All products in contact with culinary water shall comply with ANSI/NSF Standard 61.
(b) All new and repaired water mains or appurtenances shall be disinfected in accordance with AWWA Standard C651-92. The chlorine solution shall be flushed from the water main with potable water prior to the main being placed in use.
(c) All products used to recoat the interiors of storage structures and which may come in contact with culinary water shall comply with ANSI/NSF Standard 61.
(3) Reservoir Maintenance and Disinfection
After a reservoir has been entered for maintenance or re-coating, it shall be disinfected prior to being placed into service. Procedures given in AWWA Standard C651-92 shall be followed in this regard.
(4) Spring Collection Area Maintenance
(a) Spring collection areas shall be periodically cleared of deep rooted vegetation to prevent root growth from clogging collection lines. Frequent hand or mechanical clearing of spring collection areas is strongly recommended. It is advantageous to encourage the growth of grasses and other shallow rooted vegetation for erosion control and to inhibit the growth of more detrimental flora.
(b) No pesticide
(e.g., herbicide) may be applied on a spring collection area without the prior
written approval of the Executive Secretary.
Such approval shall be given 1) only when acceptable pesticides are
proposed; 2) when the pesticide product manufacturer certifies that no harmful substance
will be imparted to the water; and 3) only when spring development meets the
requirements of these rules (see [
All water system facilities such as spring junction boxes, well houses, reservoirs, and treatment facilities shall be secure.
(6) Seasonal Operation
Water systems operated seasonally shall be disinfected and flushed according to the techniques given in AWWA Standard C651-92 and C652-92 prior to each season's use. A satisfactory bacteriologic sample shall be achieved prior to use. During the non-use period, care shall be taken to close all openings into the system.
(7) Pump Lubricants
All oil lubricated pumps for culinary wells shall utilize mineral oils suitable for human consumption as determined by the Executive Secretary. To assure proper performance, and to prevent the voiding of any warranties which may be in force, the water supplier should confirm with individual pump manufacturers that the oil which is selected will have the necessary properties to perform satisfactorily.
R309-105-12. Cross Connection Control.
(1) The water supplier shall not allow a connection to his system which may jeopardize its
quality and integrity. Cross connections are not allowed unless controlled by an approved and properly
operating backflow prevention assembly.
The requirements of Chapter 6 of the [
International Plumbing Code and its amendments as adopted by the Department of
Commerce under R156-56 shall be met
with respect to cross connection control and backflow prevention.
(2) Each water system shall have a functioning cross connection control program. The program shall consist of five designated elements documented on an annual basis. The elements are:
(a) a legally adopted and functional local authority to enforce a cross connection control program (i.e., ordinance, bylaw or policy);
(b) providing public education or awareness material or presentations;
(c) an operator with adequate training in the area of cross connection control or backflow prevention;
(d) written records of cross connection control activities, such as, backflow assembly inventory; and
(e) test history and documentation of on-going enforcement (hazard assessments and enforcement actions) activities.
(3) Suppliers shall maintain, as proper documentation, an inventory of each pressure atmospheric vacuum breaker, double check valve, reduced pressure zone principle assembly, and high hazard air gap used by their customers, and a service record for each such assembly.
(4) Backflow prevention assemblies shall be inspected and tested at least once a year, by an individual certified for such work as specified in R309-305. Suppliers shall maintain, as proper documentation, records of these inspections. This testing responsibility may be borne by the water system or the water system management may require that the customer having the backflow prevention assembly be responsible for having the device tested.
(5) Suppliers serving areas also served by a pressurized irrigation system shall prevent cross connections between the two. Requirements for pressurized irrigation systems are outlined in Section 19-4-112 of the Utah Code.
R309-105-16. Reporting Test Results.
(1) If analyses are made by certified laboratories other than the state laboratory, these results shall be forwarded to the Division as follows:
(a) The supplier shall report to the Division the analysis of water samples which fail to comply with the Primary Drinking Water Standards of R309-200.
