Radon Mitigation >> EPA Radon

RADON MITIGATION STANDARDS 1.0 BACKGROUND The 1988 Indoor Radon Abatement Act (IRAA) required the Environmental Protection Agency (EPA) to develop a voluntary program to evaluate and provide information on contractors who offer radon control services to homeowners. The Radon Contractor Proficiency (RCP) Program was established to fulfill this EPA Radon portion of the IRAA. 

In December 1991, EPA published "Interim Radon Mitigation Standards" as initial guidelines for evaluating the performance of radon mitigation contractors under the RCP Program. Over the past six years, EPA Radon the effectiveness of the basic radon mitigation techniques set forth in the, "Interim Standards" has been validated in field applications throughout the United States. 

This experience now serves as the basis for the more detailed and final Radon Mitigation Standards (RMS) set forth in this document. 2.0 PURPOSE The purpose of the RMS is to provide radon mitigation contractors with uniform standards that will ensure quality and effectiveness in the design, installation, and EPA Radon evaluation of radon mitigation systems in detached and attached residential buildings three stories or less in height. 

The RMS is intended to serve as a model set of requirements which can be adopted or modified by state and local jurisdictions to fulfill objectives of their specific radon contractor certification or EPA Radon licensure programs. PARTICIPANTS Minimum requirements are established in the RMS for individuals nationwide who perform radon remediation work and wish to participate in the RCP Program. 

To participate in EPA's RCP Program, the mitigation contractor shall have completed all RCP training and examination requirements, be listed in the current RCP Listing Report, and EPA Radon shall agree to follow the provisions of the RMS. 4.0 SCOPE The requirements addressed in the RMS include the following categories of contractor activity: 

General Practices, Building Investigation, Worker Health and Safety, Systems Design, Systems Installation, Materials, Monitors and Labeling, Post-Mitigation Testing, and Contracts and EPA Radon Documentation. ASSUMPTION Before applying the provisions of the RMS, it is assumed that appropriate radon/radon decay product measurements have been performed within the structure, and that the owner has decided that radon remediation is necessary. 

IMPLEMENTATION 6.1 The RMS includes requirements for installation of radon remediation systems and provides a basis for evaluating the quality of those installations. It may be adopted by state EPA Radon regulatory agencies for state or local radon mitigation contractor licensure programs. It may also be used as a reference during inspection of in-progress or completed radon mitigation work. 

Contractors shall personally conduct follow-up inspection of any radon mitigation systems installed by their firm or by subcontractors to insure conformance with the EPA Radon requirements of the RMS. This requirement shall include the post-mitigation testing prescribed in paragraph 17.0. 6.3 EPA will evaluate reports of non- compliance with the RMS that are referred to the Agency by states and other agencies that monitor radon mitigation services. 

Based on its evaluation, EPA may initiate established RCP program de-listing procedures against contractors that the Agency or States (with certification programs) find are in violation of the mandatory EPA Radon provisions of the RMS (See paragraph 6.4). In addition, EPA or its agent may conduct inspections of radon mitigation projects. 

State radon program personnel or their contracted representatives are considered EPA agents for conducting such inspections. 6.4 Those EPA Radon provisions of the RMS that are considered to be mandatory are prefaced by the term "shall." Provisions that are considered good practice but which are not mandatory are prefaced by the terms "should" or "recommended." 6.5 

The RMS will be updated as necessary, and in response to technological advances and field experience. 7.0 LIMITATIONS 7.1 Although the provisions of the RMS have been carefully reviewed for potential conflicts with other regulatory requirements, EPA Radon adherence to the RMS does not guarantee compliance with the applicable codes or regulations of any other Federal, state, or local agency having jurisdiction. 

Where discrepancies exist between provisions of the RMS and local codes or regulations, local codes shall take precedence. However, EPA Radon where compliance with local codes necessitates a deviation from the RMS, EPA recommends that RCP listed contractors report the deviation in writing to the appropriate EPA Regional Office and the appropriate state regulatory official within 30 days. 

It should be noted that EPA is not requiring the EPA Radon reporting that is recommended in this paragraph. States with radon contractor certification programs may require that contractors give prior notification of their intent to deviate from the RMS for research or other purposes.
