RMS-MF 2018 with 12/20 Addenda

Documentation (OM&M) 41 ANSI/AARST RMS-MF 2018 (with 1220 addenda) Radon Mitigation Standards for Multifamily Buildings 10.2 When Owner Occupied 10.2.1 OM&M information packet For systems installed in an individually owned and occupied unit or dwelling , the contractor shall provide an information package labeled “Radon Mitigation Information” or similar wording that includes information and essential components of an OM&M plan in accordance with Section 10.1 Essential Information. Informative advisory —The information package should be securely attached to the system in a visible location or otherwise provided to the client . If no portion of the system is installed in the livable space, the information package should be installed in an appropriate interior location such as the mechanical room. 10.3 Non-ASD Systems When a non- ASD system is installed, additional OM&M content shall be included with the information package that provides applicable guidance from Section 12 (Non-ASD systems) and information in Table 10.5 applicable to the mitigation method(s). 10.4 Inadvertent Collateral Mitigation When mitigation is not conducted in all attached units or dwellings in a shared building, both the following statement and example notice in Figure 10.4.1 shall be prominently included with the OM&M plan to inform the client of inherent obligations to neighboring occupants: "There are inherent obligations to occupants of adjoining dwellings regarding disclosure of elevated radon concentrations found and potential effects on adjoining dwellings as a result of the mitigation system. In accordance with the ANSI/AARST standard MAMF (“Protocol for Conducting Radon and Radon Decay Product Measurements In Multifamily Buildings” ), mitigation firms are obligated to advise the client of inherent obligations to neighboring occupants. It is strongly recommended to distribute the following message in writing to occupants of adjoining dwellings and, if applicable, to the homeowners association or management firm that provides stewardship for neighboring properties.” Figure 10.4.1 Example Notice to Neighboring Property Owners and Occupants From: ___________________________________ Elevated radon concentrations were found at (addresses) ________________________________________ A mitigation system [ ] has been installed, or [ ] is planned to be installed. In the interest of health protection, we have been advised to provide you the following messages: 1) Test your home for radon — it's easy and inexpensive. Testing all homes located below the third floor is recommended. For further guidance see federal publications such as the U.S. EPA's “A Citizen's Guide to Radon” www.epa.gov/radon/citizens-guide-radon-guide-protecting-yourself-and-your-family-radon “A Radon Guide for Tenants” www.epa.gov/radon/radon-guide-tenants 2) The radon reduction system installed or planned for installation in our dwelling can inadvertently move air and extend a vacuum under some adjoining units or dwellings with the intent to stop radon entry into our dwelling. It is recommended that occupants of adjoining units: a) Seek to maximize radon reductions and energy conservation by closing openings to soil (e.g., closed covers over sumps and large holes). b) Check for any adverse impacts such as flue gas spillage from combustion appliances. 3) We cannot warrant any degree of radon reductions nor can we be responsible for maintaining radon reductions, maximizing energy conservation or checking for unlikely yet possible environmental impacts for adjoining units. For additional guidance, it is recommended to contact the state or local radon office. Sources in the U.S. include the national radon hotline at 1-800-SOS-RADON (1-800-767-7236) and state radon offices that can be found at: www.epa.gov/radon/find-information-about-local-radon-zones-and-state-contact-information.
