The Model Aquatic Health Code (MAHC) International Pool Spa Patio Expo November 2, 2016; New Orleans, LA Douglas Sackett Executive Director, CMAHC

MAHC/CMAHC and Other Acronyms Who knows about the Model Aquatic Health Code (MAHC)? Who knows about the Council for the MAHC (CMAHC)? Who is a member of the CMAHC?

AGENDA Intro to MAHC and CMAHC Selected MAHC Design and Operation Requirementsimplications & impact on pool service and maintenance Questions & Answers

Why Create the MAHC? No federal regulatory agency responsible for aquatic facilities 68% of state and local health departments regulate, inspect, or license public swimming pools 1 Significant variability in standards and requirements exist that are often outdated Significant time and resources spent by individual jurisdictions to create and update codes 1. National Association of County and City Health Officials, 2013.

MAHC Core Work Strategies The core work strategies used for MAHC development included: Use an Evolution NOT Revolution approach Build a strong partnership between public health and the aquatics sector Actively seek, listen to, and incorporate public input Rationale Incremental change is most likely to be adopted by state and local jurisdictions Partnership will yield the best product, greatest buyin, and will be most likely to be adopted Incorporating public input improves overall quality and national buy-in

Code Development Process with the MAHC MAHC was developed by expert consortia of national and international stakeholders Substantial industry participation in the process Results in better acceptance by industry 72% of >4400 public comments accepted Annex is a valuable tool that provides the data and other supporting evidence for the code requirements Updated every two years through the Council for the Model Aquatic Health Code (CMAHC)

MAHC Scope All areas of public health concern Illness, injury, drowning Public venues Water, air, & facility exposures that impact the health of swimmers and facility users Leave other areas to building codes, etc. Facility types Man-made, treated, recirculated water venues Health care-based pools Therapy pools

MAHC is Intended to Make Pools Safer: Risk Management Approach Understanding & identifying risk Drowning Disease Injury Developing methods to manage the risk Physical methods (DESIGN) Operational methods (TRAINING) Management methods (PLANNING & AUDITING) Assessing compliance

What s Inside? 1) Preface 2) User Guide 3) Glossary, Acronyms, Initialisms 4) Design and Construction 5) Operation and Maintenance 6) Policies and Management 7) MAHC Resources 8) Appendices

MAHC in Context Document type? Creation Process? Public comment? Can be updated? Enforceable? All pools? Model code, not a law CDC led, with substantial input from state and local public health, aquatics sector, and academia Evolution NOT revolution Yes, two public comment periods plus 3 rd comment period when users choose to adopt Yes, improvements based on data and expertise from public health and aquatics Must be adopted by state or local authority first No, only public facilities in adopting jurisdictions. Also, design and construction provisions mostly apply to new and remodeled construction

MAHC and Aquatics Industry Partnership Keeping Pools Safe and Keeping Pools Open are shared motivators for the MAHC and aquatics industry

The Conference for the Model Aquatic Health Code (CMAHC) What is CMAHC? 501c(3) non-profit organization Why does it exist? Established in 2013 to manage updates to the MAHC Administration & Operation Bylaws, Board of Directors, Executive Director Committees include Technical Review Committee and Ad Hoc Committees

The Conference for the Model Aquatic Health Code (CMAHC) Role Conduit for funneling advice and data-driven, sciencebased information from public health and aquatic industry experts to CDC Support use of MAHC Vision To keep the MAHC up-to-date, science-based, sustainable, easily understood and implemented by pool programs across the U.S. so as to support healthy and safe aquatic experiences for everyone.

The Conference for the Model Aquatic Health Code (CMAHC) Mission Collect, assess, and relay input on MAHC revisions back to CDC for final acceptance Provide advocacy and needed support to health departments and other partners on using the MAHC Solicit, coordinate, and prioritize research needs

CMAHC Biennial Conference CMAHC Biennial Conference will be hosted every two years Revised MAHC will be launched to coincide with Recreational Water Injury and Illnesses Week (Memorial Day) the following year Biennial CMAHC meetings: 2015, 2017, 2019, 2021, 2023, 2025, 2027, 2029 New MAHC Edition launches at CDC: 2016, 2018, 2020, 2022, 2024, 2026, 2028, 2030

Improving CR Submission Quality CMAHC sponsoring listening posts Encourage group discussion on CRs to get ideas and improvements made before submission Look at 2015 CRs that didn t pass but still have merit Can they be improved and marketed better to improve chance of passage

Improving CR Review and Member Comment Changes TRC to serve like MAHC development steering committee TRC to be backed up by 7 Technical Committees modeled after MAHC development process Design/construction, Bather supervision, etc Can reach out to tech committees for assistance with technical reviews TRC reviews to be open for members to hear discussion not open for two way conversation vs. member comment submission

Aquatic Venue Water Contamination Response Formed-Stool With or without chlorine stabilizers Diarrheal-Stool With or without chlorine stabilizers Vomit-Contamination With or without chlorine stabilizers Blood-Contamination Procedures for Brominated Pools

Aquatic Venue Water Contamination Response Close Venue Physical Removal and disposal of contaminating material Treat venue water (when contaminated by feces or vomit) Check to ensure that the water s ph is 7.5 or lower and adjust if necessary; Verify and maintain water temperature at 77 F (25 C) or higher; Operate the filtration/recirculation SYSTEM while the POOL reaches and maintains the proper free CHLORINE concentration during the remediation process; Test the CHLORINE residual at multiple sampling points to ensure the proper free CHLORINE concentration is achieved throughout the POOL for the entire DISINFECTION time; and Use only non-stabilized CHLORINE products to raise the free CHLORINE levels during the remediation.

Aquatic Venue Water Contamination Response Formed-Stool without chlorine stabilizers Formed-stool contaminated water shall have the FREE CHLORINE RESIDUAL checked and the FREE CHLORINE RESIDUAL raised to 2.0 mg/l (if less than 2.0 mg/l) and maintained for at least 25 minutes (or an equivalent time and concentration to reach the CT INACTIVATION VALUE) before reopening the AQUATIC VENUE. Formed-Stool with chlorine stabilizers In AQUATIC VENUE water that contains CYA or a stabilized CHLORINE product, water shall be treated by doubling the inactivation time required under MAHC 6.5.3.1.

Aquatic Venue Water Contamination Response Diarrheal-Stool without chlorine stabilizers Check the FREE CHLORINE RESIDUAL and then raise the FREE CHLORINE RESIDUAL to 20.0 mg/l and maintain for at least 12.75 hours (or an equivalent time and concentration to reach the CT INACTIVATION VALUE) before reopening the AQUATIC VENUE, or Circulate the water through a SECONDARY DISINFECTION SYSTEM to theoretically reduce the number of Cryptosporidium OOCYSTS in the AQUATIC VENUE below one OOCYST/100 ml as outlined in MAHC 4.7.3.3.2.4.

Aquatic Venue Water Contamination Response Diarrheal-Stool with chlorine stabilizers HYPERCHLORINATION accomplished by: o Following the preparatory guidance outlined in MAHC 6.5.2.3; o Lowering the CYA concentration to less than or equal to 15 ppm by draining, if necessary; o Raising the FREE CHLORINE RESIDUAL to 20 mg/l for at least 28 hours; 30 mg/l for at least 18 hours; 40 mg/l for at least 8.5 hours; o Measurement of the inactivation time required shall start when the AQUATIC VENUE reaches the intended FREE CHLORINE RESIDUAL level or; Circulating the water through a SECONDARY DISINFECTION SYSTEM to theoretically reduce the number of Cryptosporidium OOCYSTS in the AQUATIC VENUE below one OOCYST/100 ml as outlined in MAHC 4.7.3.3.2.4 or; Draining the AQUATIC VENUE completely.

Aquatic Venue Water Contamination Response Procedures for brominated pools** Formed-stool, diarrheal-stool, or vomit-contaminated water in a brominated AQUATIC VENUE shall have CHLORINE added to the AQUATIC VENUE in an amount that will increase the FREE CHLORINE RESIDUAL to the level specified for the specific type of contamination for the specified time. **There are no inactivation data for Giardia or Cryptosporidium for bromine or any developed protocols for how to hyperbrominate a swimming POOL and inactivate pathogens that may be present in fecal matter or vomit.
