The formulation of radon standards was mandated by the Indoor Radon Abatement Act of 1988. The Radon Mitigation Standards were formulated in an April 1993 document (with minor revisions in 1994) that replaces the interim Mitigation standards of 1991. The standards include but are not limited to the points below.
Require your mitigator to be certified (currently, that means NEHA- or NRSB-certified),
and require him/her to follow at least the following EPA recommendations:
1)
Follow requirements for contractual considerations and achievement of required final
low level of Radon concentration.
2) Follow requirement for client exposure to
solvents, and have MSD-sheets available.
3) Perform a thorough building investigation
4)
Follow building codes when installing mitigation systems.
5) Install vent pipes
permanently sealed and well protected from accumulation of condensate.
6) Recommend
certain records be kept for 3 to 20 years.
7) Follow electrical codes during installation.
8)
Mitigator has knowledge
of alternative systems
9) Requirements on materials, such as pipe schedules,
fittings, joints, Urethanes,grouts, foams, non-permanent caulks and cross-laminated
membranes and treated wood.
10) Proper monitoring and labeling of final system.
11)
Required performance of a Post-Mitigation test, either by contractor or independent
third party.
12) Certain documents are required to be provided to the Client at
the end of the mitigation such as, but not limited to, building permits (if local
Code requires), investigation summary, pre- and post-mitigation test data. Contract/warranty
copy; system description; deviations from standard system if applicable; Operation/maintenance
procedures. Actions to take when monitor indicates system failure.
