There may be a small financial savings, but the amount cannot be estimated because it is so minimal. The efficiency gain from removing this step is primarily qualitative.
E. Persons other than small businesses, non-small businesses, state, or local government entities ("person" means any individual, partnership, corporation, association, governmental entity, or public or private organization of any character other than an agency):
The proposed rule may see a savings on a homeowner that would need to install a booster pump. There is no way for us to know how many homeowners would have a need to install booster pumps, so we are unable to estimate any savings.
F. Compliance costs for affected persons:
The proposed rule may see a savings on a homeowner that would need to install a booster pump.
There is no way for the Division to know how many homeowners would have a need to install booster pumps, so are unable to estimate any savings.

R309-540-6. Pumps.
(1) [Capacity and Minimum Distribution System Pressure. ]A pump used to provide minimum distribution system pressure shall: (a) have the capacity to meet the maximum demand of the specific portion of the distribution system served; and
(b) be capable of providing the minimum pressure[s required by] requirements of Section R309-105-9. (2[a]) [A water supplier shall have at least two pumps installed and in operation at a booster pump facility that provides the only means available to meet the minimum distribution system pressure requirements of Section R309-105-9 for the water distribution pipeline served by the facility.]If a pump station is the only means available for a community PWS to meet the minimum distribution system pressure requirements of Section R309-105-9, the pump station shall have at least two pumps in operation.(a) Transient and non-transient non-community PWSs shall have at least one pump in operation to maintain the minimum distribution system pressure requirements of Section R309-105-9. If the director finds that unplanned closures could cause harm to public health, the director may require a transient or non-transient non-community PWSs to install at least two pumps to maintain minimum distribution pressure. (b) Transient and non-transient non-community PWSs that have only one pump in operation shall have a backup pump available that is ready to install if necessary. (3[b]) [A booster]In a pump station[facility] that requires at least two pumps, if the largest pump is out of service, the second pump shall have the capacity to meet the maximum demand of the water distribution pipeline served by the pump station.[facility with the largest pump out of service.] (4[3]) Each [B]booster [P]pump[s.]: (a) [A booster pump ]shall [be equipped with]have an automatic shutoff or low-pressure controller as recommended by the pump manufacturer;[.] (b) [A booster pump]that withdraws[ing] water from a distribution line shall maintain an intake pressure of at least 20 psi when the pump is in normal operation;[.] (c) [A booster pump]that withdraws[ing] water directly from a water storage tank shall [be provided with ]have net positive suction head. (5[4]) [Pump Motor. ]A pump motor shall: (a) [be sized]have the capacity to meet operating conditions without overloading; and (b) provide the maximum horsepower necessary to run [required by ]the pump without the use of a service factor. [(5) Certification of Drinking Water Treatment Chemicals and System Components. (a) Chemicals added to drinking water at pump facilities shall be certified to meet NSF/ANSI 60.] (6[b]) [Products, components, and]Any material[s used] that may come in contact with drinking water in a pump facility [facilities that may impart chemical contaminants or impurities to drinking water ]shall be certified to meet NSF/ANSI 61. (7[6]) [Suction Lift.]Any pump with suction lift shall:[ When a pump provides suction lift:] (a) [the maximum lift shall ]be within the pump manufacturer's recommended limits; and (b) [tanks]have priming [shall be provided ]for the pump. ](8[a]) When a pump requires priming, the priming system shall: (a[i]) use water of at least the same quality that the pump is pumping; [as the water being pumped; ]and (b[ii]) include a means to prevent back siphoning. (9[b]) For vacuum priming that uses an [When an ]air-operated ejector, the ejector [is used for vacuum priming, it ]shall draw clean air through a screened intake that is: (a[i]) at least ten feet above the ground; and (b[ii]) at least ten feet away from a point of contamination. ](10[a]) A pump that uses water for a seal [Water used as a seal for a pump ]shall have water [be ]of at least the same quality that the pump is pumping[of the water being pumped].[ (b) ] A water line supplying drinking water [used as ]for a seal for a pump that pumps non-potable water shall have backflow protection.[be protected from backflow.] [(9) Individual Home Booster Pumps. Individual home booster pumps shall not be allowed for any individual service from the public water supply main. Exceptions may be granted by the Director if it can be shown that the granting of an exception will not jeopardize public health. ](11) A booster pump within the premise plumbing of a building or on the service lateral connection, including a home booster pump, is acceptable if: (a) the pump is not necessary to resolve deficiencies related to the necessary minimum pressures at the point of connection for the service lateral per Section R309-105-9; (b) the PWS approves the pump installation; and (c) the pump installation and operation meet the applicable requirements in the International Plumbing Code and any amendments that the Department of Commerce has adopted.
