This rule is promulgated by the Drinking Water Board as authorized by Title 19, Environmental Quality Code, Chapter 4, Safe Drinking Water Act, Subsection 104 of the Utah Code and in accordance with 63G-3 of the same, known as the Administrative Rulemaking Act.
Definitions for certain terms used in this rule are given in R309-110 but may be further clarified herein.
(1) Water suppliers are responsible for the quality of water delivered to their customers. In order to give the public reasonable assurance that the water which they are consuming is satisfactory, the Board has established rules for the design, construction, water quality, water treatment, contaminant monitoring, source protection, operation and maintenance of public water supplies.
(2) For compliance monitoring required by R309-200 through 215, public water systems must use a laboratory certified by the Utah Public Health Department in accordance with R444-14-4. The Federal Safe Drinking Water Act requires each analyte to be analyzed by a specific method. These methods are described in the July 1, 1992 through 2015, editions of 40 CFR Parts 141, 142, and 143 (Safe Drinking Water Act).
(1) The applicable requirements specified in R309-205, R309-210 and R309-215 for monitoring shall apply to each public water system, unless the public water system meets all of the following conditions:
(a) Consists only of distribution and storage facilities (and does not have any collection and treatment facilities);
(b) Obtains all of its water from, but is not owned or operated by, a public water system to which such regulations apply;
(c) Does not sell water to any person; and
(d) Is not a carrier which conveys passengers in interstate commerce.
(2) When a public water system supplies water to one or more other public water systems, the Director may modify the monitoring requirements imposed by R309-205, R309-210 and R309-215 to the extent that the interconnection of the systems justifies treating them as a single system for monitoring purposes.
(3) In no event shall the Director authorize modifications in the monitoring requirements which are less stringent than requirements established by the Federal Safe Drinking Water Act.
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 Director 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 Director 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 Director prior to approval of any plans or specifications for projects described in R309-500-4(1) as new or previously un-reviewed water system.
(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 R309-500 through R309-550 of these rules. The Director may require modifications to plans and specifications before approval is granted.
(b) There may be times in which the requirements of the applicable standards contained in R309-500 through R309-550 are not appropriate. Thus, the Director 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. In order for the Director to consider such a request, the public drinking water system shall submit a written request directly from the management of the public dinking water system, preferably on system letterhead, that includes the following:
(i) citation of the specific rule for which the "exception" is being requested;
(ii) a detailed explanation, drawings may be included, of why the conditions of rule cannot be met;
(iii) what the system proposes, drawings may be included, in lieu of rule;
(iv) justification the proposed alternative will protect the public health to a similar or better degree than required by rule.
Physical conditions as well as cost may be justification for requesting an "exception-to-rule."
(c) Alternative or new treatment techniques may be developed which are not specifically addressed by the applicable standards contained in R309-500 through R309-550. These treatment techniques may be accepted by the Director 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 R309-500 through R309-550.
(iii) The technique is as reliable as any comparable treatment process governed by the applicable standards contained in 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 Director.
(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.
(1) Public Water Systems are responsible for protecting their sources of drinking water from contamination. R309-600 and R309-605 sets forth minimum requirements to establish a uniform, statewide program for implementation by PWSs to protect their sources of drinking water. PWSs are encouraged to enact more stringent programs to protect their sources of drinking water if they decide they are necessary.
(2) R309-600 applies to ground-water sources and to ground-water sources which are under the direct influence of surface water which are used by PWSs to supply their systems with drinking water.
(3) R309-605 applies to PWSs which obtain surface water prior to treatment and distribution and to PWSs obtaining water from ground-water sources which are under the direct influence of surface water. However, compliance with this rule is voluntary for public transient non-community water systems to the extent that they are using existing surface water sources of drinking water.
(1) All public water systems shall deliver water meeting the applicable requirements of R309-200 of these rules.
(2) Existing facilities shall be brought into compliance with 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).
(1) Unless otherwise specifically approved by the Director, no water supplier shall allow any connection to the water system where the dynamic water pressure at the point of connection will fall below 20 psi during the normal operation of the water system. Water systems approved prior to January 1, 2007, are required to maintain the above minimum dynamic water pressure at all locations within their distribution system. Existing public drinking water systems, approved prior to January 1, 2007, which expand their service into new areas or supply new subdivisions shall meet the minimum dynamic water pressure requirements in R309-105-9(2) at any point of connection in the new service areas or new subdivisions.
(2) Unless otherwise specifically approved by the Director, new public drinking water systems constructed after January 1, 2007 shall be designed and shall meet the following minimum water pressures at points of connection:
(a) 20 psi during conditions of fire flow and fire demand experienced during peak day demand;
(b) 30 psi during peak instantaneous demand; and
(c) 40 psi during peak day demand.
(3) Individual home booster pumps are not allowed as indicated in R309-540-5(4)(c).
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 Director.
(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 Director. Residual checks shall be taken a minimum of three times each week by the operator of any system using disinfectants. The Director 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 Director. 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 R309-515-7).
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 Director. 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.
All community and non-transient non-community water systems or any public system that employs treatment techniques for surface water or ground water under the direct influence of surface water shall have an appropriately certified operator in accordance with the requirements of these rules. Refer to R309-300, Certification Rules for Water Supply Operators, for specific requirements.
(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 2009 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 in-line serviceable (repairable), in-line testable and have certification through third party certifying agencies to be used within a public drinking water system. Third party certification shall consist of any combination of two certifications, laboratory or field, performed by a recognized testing organization which has demonstrated competency to perform such tests.
(5) 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.
(6) 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.
All public water systems are required to monitor their water according to the requirements of R309-205, R309-210 and R309-215 to determine if the water quality standards of R309-200 have been met. Water systems are also required to keep records and, under certain circumstances, give public notice as required in R309-220.
(1) Written Operational Reports.
(a) If, in the opinion of the Director, a water system is not properly operated, the Director may require a public water system to submit a written operational report covering the operation of the whole or a part of the water system's infrastructure.
(b) The Director may require revisions to the submitted operational report to ensure satisfactory operation, and may order the water system to follow the operational report.
(c) If the water system fails to implement the provisions of the operational report, as evidenced by unsatisfactory delivery of a safe and/or reliable supply of drinking water, the Director may order further remedies as deemed necessary.
(2) Treatment techniques for acrylamide and epichlorohydrin.
(a) Each public water system shall certify annually in writing to the Director (using third party or manufacturer's certification) that when acrylamide and epichlorohydrin are used in drinking water systems, the combination (or product) of dose and monomer level does not exceed the levels specified in R309-215-8(2)(c).
(b) Certifications may rely on manufacturer's data.
(3)(a) All water systems using chemical addition or specialized equipment for the treatment of drinking water shall regularly complete operational reports. This information shall be evaluated to confirm that the treatment process is being done properly, resulting in successful treatment.
(b) The information to be provided, and the frequency at which it is to be gathered and reported, will be determined by the Director.
All community water systems shall be required to complete annual report forms furnished by the Division of Drinking Water. The information to be provided shall include: the status of all water system projects started during the previous year; water demands met by the system; problems experienced; and anticipated projects.
(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. Except where a different reporting period is specified in R309-205, R309-210 or R309-215, this report shall be submitted within 48 hours after the supplier receives the report from his lab. The Division may be reached at (801)536-4200.
(b) Monthly summaries of bacteriologic results shall be submitted within ten days following the end of each month.
(c) All results of TTHM samples shall be reported to the Division within 10 days of receipt of analysis for systems monitoring pursuant to R309-210-9.
(d) For all samples other than samples showing unacceptable results, bacteriologic samples or TTHM samples, the time between the receipt of the analysis and the reporting of the results to the Division shall not exceed 40 days.
(e) Arsenic sampling results shall be reported to the nearest 0.001 mg/L.
(f) There are additional reporting requirements in other sections of the rules, see R309-215-16(5).
