9. Change Request #39  Submitter presentation: Lars Hagen, AquaCal AutoPilot, Inc.  Summary: Transition chlorinator sizing away from one number for all to performance based criteria

10. * 4.7.3.2.2.2 Chlorine Dosing * All chlorine dosing and generating equipment…. shall be designed with a capacity to provide and maintain Free Available Chlorine (FAC) levels as specified in Section 5.7.3.1.1.2. (which are minimum FAC concentrations of 1,2 or 3 ppm based on Aquatic Venue) * 4.7.3.2.2.3 Rates * The engineer shall address the following factors when sizing the feeders/equipment: * Pool surface area * Pool volume * Pool type: Pool, Spa, Kiddie/Wading Pool,… * Indoor/Outdoor….. * And other chlorine demand factors….

11. * MAHC Research Agenda – Tier 1 (needed to make short term improvements in MAHC) * Develop guidance and supporting data to enable appropriate sizing of feeders. * Collect data on chlorine usage in real world pool situations under different environmental and operational conditions to inform development of an effective rate law from which the sizing of chemical feed pumps could then be calculated. * Once actual chlorine usage is obtained, a surplus safety factor could be introduced to slightly oversize the feed pump to ensure that the disinfectant dosing amount can be increased to meet increases in demand. * Any such sizing requirements need to specify the timeframe within which the pump must be able to satisfy the chlorine dosing required.

12. * Due to time constraints, the workgroup was not able to gather and/or analyze data from enough pools in sufficient detail to address different environmental and operational conditions as specified in the research agenda. * Based on the available data, the CMAHC Chlorinator Sizing Workgroup sub-committee's preliminary analysis indicates that there is not a direct correlation between actual chlorine consumption vs. aquatic venue volume, and that other factors should be included in the engineering design dosing capacity of chlorine per day. * The preliminary analysis indicates that currently there is not an ideal dosage rate formula. * The analysis also indicates that the current MAHC/code requires a higher feeder capacity than necessary to meet demand.

13. * One of the key precepts of the MAHC is that it be performance-based where possible. Below is the proposed performance-based revision to the MAHC, included in the submitted Change Request (CR39). Prescriptive dosing levels (# lbs of FAC/day/10,000 gal) were considered, but revised dosing levels based on the available data could not be defended nor did the data support the existing rates. * To better design chlorine dosing capacity for aquatic venues and revise the MAHC accordingly, a formal scientifically gathered data collection and analysis effort is recommended. The CMAHC intends to pursue this additional data collection and analysis recommendation. * The sub-committee is preparing an interim progress report which will be passed on to the CMAHC. It will then be posted on the CMAHC website.

16. CR39: Annex Language  The CMAHC established a Chlorinator Sizing Workgroup to address chlorinator sizing by collecting and analyzing actual chlorine consumption at operating pools. Based on the available data collected, the CMAHC Chlorinator Sizing Workgroup sub-committee's preliminary analysis indicates that there is not a direct correlation between actual chlorine consumption vs. aquatic venue volume, and that other factors should be included in the engineering design dosing capacity of chlorine per day. The preliminary analysis indicates that currently there is not an ideal dosage rate formula. The analysis also indicates that the current MAHC/code requires a higher feeder capacity than necessary to meet demand. One of the key precepts of the MAHC is that it be performance-based where possible. Performance-based revision to the MAHC have replaced prescriptive dosing levels(# lbs of FAC/day/10,000 gal.). Revised prescriptive dosing levels were considered, but dosing levels based on the available data could not be defended, nor did the data support the existing rates. To better design chlorine dosing capacity for aquatic venues and revise the MAHC accordingly, a formal scientifically gathered data collection and analysis effort is recommended. The CMAHC intends to pursue this additional data collection and analysis recommendation.  An interim progress report by the CMAHC Chlorinator Sizing Workgroup will be posted on the CMAHC website.

27. TUESDAY PM CR PRESENTATIONS SECTION 5 CR’S 51, 52, 56/58/99/156

28. Change Request #51  Submitter presentation: John Kelly, IA Dept. of Health  Summary: Places limits on use of wing walls: not on zero entry, not next to 5 feet of water, or in areas where depths differ by more 6 inches

29. CR51-Issue: Drowning Prevention  4.8.1.6.7 Wing wall uses Wing walls shall not be used immediately adjacent to a zero depth entry, immediately adjacent to water depths greater than 5 feet in depth, or to separate sections of pools with water depths varying by more than 6 inches in water depth.  Wing walls create large physical obstructions limiting visibility into a swimming pool and abrupt depth changes across wing wall can allow young non-swimmers to quickly and quietly access water that is too deep. Generally these young non-swimmers are separated by non climbable barriers or distance from deeper water

30. CR51-Issue: Drowning Prevention  Data from CDC Wonder, appears to indicate the rate of drowning and submersion deaths associated with swimming pools for young children has been trending higher since 1999.

31. CR51-Issue: Drowning Prevention  Wing walls used immediately adjacent to a zero depth entry places young children only a step away from a serious drowning hazard

32. CR51-Issue: Drowning Prevention  Wing walls used immediately adjacent to deep water limit the lifeguard access and visibility into the deep water

33. CR51-Issue: Drowning Prevention  In this pool a wing wall is used to separate an 18” deep toddler play area from a current channel. In the drowning incident that occurred the child was with his sibling in the zero depth entry before he was recovered from the current channel. It appeared likely he entered the channel over the wing wall or through the underwater stairs.

35. Change Request #52  Submitter presentation: John Kelly, IA Dept. of Health  Summary: Diving board change requiring railings and stairs for all boards 1 meter or higher

36. CR52-Issue: Injury Prevention  4.8.2.2.4 Tall Platforms Diving stands or platforms that are 1 meter or higher two meters (6.6 ft) or higher must have guard rails with the top rail at least 36 inches (0.9 m) above the board and a second rail approximately half the distance from the platform to the upper rail. Diving boards or platforms greater than 1 meter (3.3 ft) in height shall be accessed by a stairway. The stair railing and diving board or platform guard rails shall be designed to prevent falls and extend past the pool edge.  There have been many injuries and multiple deaths associated with falls from the ladder or board at 3 meter stands. Many of these injuries and deaths could be eliminated through design changes that can make these diving boards safer by removing the vertical ladder replacing it with a stairway and improving the guardrails at the diving board.

37. CR52-Issue: Injury Prevention  There have been many injuries from falls and multiple deaths associated with falls from 3 meter boards and I found reference to at least one large award in a lawsuit.

38. CR52-Issue: Injury Prevention  Many 3 meter boards are being removed due to the injuries that are being experienced many associated with falls from the ladder or diving board onto the concrete below.

39. CR52-Issue: Injury Prevention  Paddock Industries has gone as far as to recommend on their info center that both one and three meter boards should never be used for recreation and that diving equipment should only be used under direct supervision of a diving instructor.

40. CR52-Issue: Injury Prevention  USA Diving recognizes the need to train their athletes to climb up and down the ladder to the springboards

41. CR52-Issue: Injury Prevention  Facility operators who do not remove the 3 meter boards have no clear direction in how to make them safe for recreational use. Some impose age or height limits. Others have resorted to waivers.

42. CR52-Issue: Injury Prevention  One manufacturer that I checked with does not provide an owners manual. They indicated no age or height restrictions are recommended.

43. CR52-Issue: Injury Prevention  The photo is from an inspection this summer. On the inspection I almost fell due to the inconsistent spacing of the rungs. While every other rung is slightly offset, the top rung leaves a hole of over 8”.

45. Change Request #56/58/99/156  Submitter presentation: TRC  Summary: All related to complete deletion of sections that are perceived as administrative guidance (regulating the regulator) including  Operating permits (CR56)  Inspections (CR58)  Waiver language speaking to AHJ (CR99)  AHJ Inspections (CR156)  Sections contain parts that speak to operators  Cut all or surgically remove specific AHJ wording?

46. Change Request #56/58/99/156  Submitter presentation: TRC  TRC Review: Sections contain parts that speak to operators  Cut all or surgically remove specific AHJ wording?

47. TRC Review #56/58/99/156  TRC Review: While it is understood that AHJ’s want to adopt the MAHC by reference, the need for the basic terminology appears valid to be displayed in the MAHC. The consensus was that these items need to remain in the rule and have specific changes to meet AHJ needs met by them for their compliance. Specific to this section, the owner is typically responsible for operating permits and annual inspections required by local departments of health. Inclusion of the details in the code informs the owner/operator of their responsibilities  Sections contain parts that speak to operators  All except 99 cut entire sections vs. surgically removing inappropriate AHJ language
