Environmental Protection Agency (EPA).


Notice of availability; opening of a 60-day public comment period.


Since 1988, the Environmental Protection Agency (EPA) has administered a statutorily-mandated program under the Indoor Radon Abatement Act to reduce exposure to indoor radon by promoting awareness, testing, installation of radon mitigation systems in existing homes, and use of radon-resistant new construction techniques. EPA works with state programs, industry and the public to reduce human exposure to radon and thereby reduce deaths due to lung cancer. Access to quality service providers responsible for measuring indoor radon levels and conducting mitigation when necessary is essential to this mission. Historically, EPA operated a program, the Radon Proficiency Program (RPP), to identify qualified radon service providers, a service to assist consumers and states receiving indoor radon grants. Upon its discontinuation, two organizations qualified to be designated as responsible parties for credentialing radon service providers in the absence of a state-run process established under a state's regulatory requirements. Since that time, there has not been an ongoing and open evaluation process for organizations wanting to credential radon service providers. As the Federal agency responsible for implementing the national radon program, and in response to the needs of our state and private partners, EPA intends to establish voluntary criteria outlining a standard of competence for organizations that credential radon service providers. This notice provides interested parties with an opportunity to provide feedback on the Agency's proposed approach.

Voluntary Consensus Standards (VCS): Standard developed or adopted by voluntary consensus standards bodies, through the use of a voluntary consensus standards development process, as defined in OMB A-119.

II. Background

A. What authority does EPA have to establish voluntary criteria for radon credentialing organizations?

The 1988 Indoor Radon Abatement Act (See Toxic Substances Control Act, Start Printed Page 39995Title III; 15 U.S.C. 2661-2671) addresses risks associated with indoor radon levels and establishes provisions that focus on voluntary activities, including education and grant and technical assistance to states for radon programs. Under 15 U.S.C. 2665(a)(2), EPA was granted authority to operate a voluntary proficiency program for rating, among other things, the effectiveness of radon measurement and mitigation devices and methods, and “the effectiveness of private firms and individuals offering radon-related architecture, design, engineering, measurement, and mitigation services.” Pursuant to 15 U.S.C. 2666(h)(3), state grant recipients are required to maintain, and make available to the public, a list of firms and individuals receiving a passing rating under such a program.

B. What is the history of EPA's voluntary Radon Proficiency Program for radon service providers?

In February 1986, EPA established the Radon Measurement Proficiency (RMP) Program to assist consumers in identifying organizations capable of providing reliable radon measurement analysis services. The Radon Contractor Proficiency (RCP) Program was established in 1989 to evaluate the proficiency of radon mitigators in residences and provide information to the public on proficient mitigators. In 1994, EPA began working to consolidate the RMP and RCP into one streamlined program to better meet industry needs and reduce costs. The consolidated program officially became the Radon Proficiency Program (RPP) in October 1995.

In response to stakeholder feedback as part of the RPP development-process, the Agency also began investigating the feasibility of transitioning oversight of the proficiency program away from EPA. The Agency tasked the Conference of Radiation Control Program Directors (CRCPD) with drafting a document containing the necessary components of a proficiency program. As part of this effort, a series of stakeholder meetings were held in 1997. Feedback was collected in five key areas critical to discontinuation of the EPA's RPP: (1) Radon tester; (2) radon mitigator; (3) approval and accreditation requirements for radon and radon decay product measurement devices, radon chambers, and radon laboratories; (4) the operational board and committees; and (5) the transition to private proficiency programs.

Ultimately, CRCPD developed a final document outlining a plan for transitioning oversight of the proficiency program outside of the Federal government, entitled: “Criteria for Certification of Radon Service Providers, the Accreditation of Radon Chambers and Laboratories, and the Approval of Measurement Devices.” This plan was used to conduct a one-time evaluation and identify two organizations that sufficiently addressed components of EPA's RPP in the early 2000s. These two organizations—the National Radon Proficiency Program (NRPP; initially affiliated with the National Environmental Health Association and currently affiliated with the American Association of Radon Scientists and Technologists, or AARST) and the National Radon Safety Board (NRSB)—became responsible for credentialing radon service providers in the absence of a state run process established under a state's regulatory requirements. This service assisted consumers by identifying qualified radon providers. In addition, it assisted states receiving indoor radon grants, which are required to maintain and make available a list of qualified service providers to the public. Since the discontinuation of the RPP, the Agency has relied on NRPP, NRSB and state run certification programs to provide the national proficiency platform in the radon marketplace.

C. What is the framework for EPA's consideration of voluntary consensus standards and conformity assessment activities?

Taken together, the National Technology Transfer and Advancement Act (NTTAA, Pub. L. 104-113), Office of Management and Budget Circular A-119 (OMB A-119) and Guidance on Federal Conformity Assessment (15 CFR part 287) direct Federal agencies to use voluntary consensus standards (VCS) wherever possible as the basis of regulation and other programs, to participate in the development of VCS, and to coordinate conformity assessment activities (testing, certification, etc.) with the private sector to avoid duplication. OMB A-119 outlines considerations Federal agencies should make when addressing the need for conformity assessment, and considerations agencies should take into account when designing conformity assessment programs.

Personnel certification has become an important element of verifying the competence of an increasingly mobile and global workforce. In response to this growing need, a joint technical committee of the International Organization for Standardization and the International Electrotechnical Commission (the ISO/IEC) developed an international standard to establish uniform procedures for certifying the competence of personnel in different occupations or professions. The ISO/IEC 17024:2012 standard is designed to help ensure that personnel certification programs run by credentialing organizations (also referred to as a certifying body) operate in a consistent, comparable, impartial and reliable manner. In addition to ensuring the validity of individual certification programs, the ISO/IEC standard is intended to help ensure competence and quality of a workforce and promote consumer and public confidence. Key areas addressed in the standard include: The structure and governance of the certifying body and the characteristics of the certification program as it relates specifically to a job type (e.g., a certification scheme) and the assessment and recertification requirements.

To verify compliance with ISO/IEC standard 17024:2012, credentialing organizations may seek accreditation from a third party. An organization accredited by a third party demonstrates ongoing compliance with a set of business standards and the necessary core competencies to perform the certification of persons and/or training functions. As a requirement of continuous accreditation recognition, an organization must demonstrate ongoing compliance with ISO/IEC standard 17024:2012 by periodically maintaining accreditation.

III. Subject and Purpose of This Notice

Radon exposure causes approximately 21,000 lung cancer deaths every year and is the leading environmental cause of cancer deaths. Many state programs and private industry stakeholders have, for years, asserted their belief that EPA should maintain a standard of competence for organizations credentialing radon service providers that reflect current industry standards and best practices. There is no current formal process to assess quality and competence of organizations wanting to credential radon service providers. The Agency believes it is necessary to establish an ongoing and open evaluation process moving forward and anticipates that it will take two to four years to establish a process and ensure ample opportunities for stakeholder involvement. Criteria establishing a standard of competence for organizations credentialing radon service provides will help ensure continued and sustained access to a qualified workforce.

EPA recently issued a special term and condition to SIRG grantees clarifying guidance in the State and Start Printed Page 39996Tribal Indoor Radon Grants Program Guidance and Handbook​sites/​production/​files/​2014-08/​documents/​guidance_​and_​handbook.pdf related to satisfying requirements for 15 U.S.C. 2666(h)(3). Specifically, the Agency clarified that, to remain in compliance with 15 U.S.C. 2666(h)(3) requirements, states receiving SIRG funding must maintain and provide the public with a list of only those radon service providers who are credentialed either through:

(1) An existing state-run process established under a state's regulatory requirements for credentialing radon service providers (e.g., state license), or

(2) one of the two currently-recognized national radon proficiency programs (i.e., NRPP or NRSB).

The term and condition will remain in effect until the Agency issues voluntary criteria, at which time, states receiving SIRG funding would list only those radon service providers credentialed by organizations meeting the criteria.

A. What specific comments are being sought?

While all comments regarding any aspect related to the development of voluntary criteria for radon credentialing organizations are welcomed, comments on the following key areas are specifically requested.

1. Overall Approach

While EPA cannot require that radon credentialing bodies take any particular action in order to conduct business, EPA does have authority to require that states receiving indoor radon grants list only providers who meet certain standards of competence. By establishing criteria for organizations credentialing radon service providers, EPA would help states ensure high-quality radon services are available to their citizens. States receiving SIRG funding would be required to list only radon service providers who are certified by organizations meeting these criteria (possibly including state-run credentialing programs).

To satisfy the criteria, organizations that credential radon service providers would need to demonstrate and maintain compliance with ISO/IEC standard 17024:2012 through independent, third party accreditation. The voluntary criteria would specify a timeframe for organizations to demonstrate compliance with ISO/IEC 17024:2012 through third party accreditation.

As a condition of continuous accreditation recognition, an organization would need to demonstrate ongoing compliance with ISO/IEC 17024:2012 by periodically reapplying and earning accreditation.

Credentialing organizations accredited to ISO/IEC 17024:2012 have to ensure that certificate holders meet requirements outlined in the certification scheme. The credentialing organization may use recertification to bring those who do not meet the current requirements into compliance. In this case, recertification may be required for service providers previously credentialed by one of the two national credentialing organizations.

EPA is seeking comments on the overall feasibility, appropriateness and potential impacts of these criteria, in particular as they relate to: Time-frame for demonstrating compliance through third-party accreditation and options for a phased-in approach, maintaining continuous accreditation, and recertification as a means to bring existing certificate holders into compliance.

2. Application of Voluntary Criteria to State-Run Programs

Currently, approximately twenty-three states have regulatory requirements in place for credentialing of radon service providers and implement a process accordingly (e.g., state license). While some of these states require certification by one of the two currently recognized national credentialing organizations (i.e., NRPP and/or NRSB), there are states operating processes that do not require this certification.

EPA is seeking comments on the feasibility, appropriateness and potential impacts of requiring states that operate independent programs (i.e., currently do not require certification by one of two recognized national credentialing organizations) to meet the criteria if receiving SIRG funding.

3. Requirements for Accreditation Organizations

Organizations providing independent, third party accreditation may be required to demonstrate compliance with ISO/IEC 17011:2004 as a signatory of the International Accreditation Forum's Multilateral Recognition Agreement, or MRA.

EPA is seeking feedback on the value of including conditions for organizations providing independent, third party accreditation.

4. Development of ISO/IEC 17024:2012 Program-Related Components

To help reduce the burden to credentialing organizations seeking accreditation to the ISO/IEC 17024:2012 and to standardize competency and testing requirements for radon service providers, EPA recognizes that there may be value in the Agency supporting development of the certification scheme, a requirement of ISO/IEC 17024:2012. It should be noted that the choice of what role EPA plays ultimately will depend on both what the community needs and what resources the Agency can sustainably support.

EPA is seeking comments on the feasibility, appropriateness, and potential impacts of each possible scenario presented below:

(a) EPA develops basic framework for credentialing organizations to follow.

EPA would define parameters for the certification scheme (e.g., scope(s) of practice, use of existing American National Standards Institute/American Association of Radon Scientists and Technologists (ANSI/AARST) measurement and mitigation voluntary consensus standards when developing the job task analysis (JTA), recertification requirements).

Credentialing organizations might enter into a Memorandum of Understanding with EPA committing to develop and maintain a certification scheme in compliance with specified parameters.

(b) EPA supports development of initial certification scheme.

EPA would support development of the initial certification scheme and then would transfer ownership of the scheme to a third party or individual credentialing organization(s) after a specified time-frame (e.g., five years). In this case, new scheme owners might sign a licensing agreement transferring ownership of the certification scheme and stipulating conditions for use and maintenance of the scheme. For example, the licensing agreement may specify that the scheme owner may only make changes to the scheme that are deemed more stringent.

(c) EPA supports development and maintenance of certification scheme.

EPA would retain ownership of the certification scheme, including development and maintenance. Organizations seeking accreditation to ISO/IEC 17024:2012 might enter into a licensing agreement with the Agency which would specify requirements for use of the certification scheme.

5. Scope of This Effort

EPA's RPP addressed labs and devices in addition to radon testing and mitigation service providers. The proposed approach outlined above does not directly address labs and devices. If the Agency were to address labs, a different ISO/IEC standard would apply Start Printed Page 39997(17025) and would require an independent process. Device requirements for certified radon service providers will be incorporated within the scope of this effort. (e.g., device must have demonstrated compliance with the voluntary consensus standard MS-PC 2015, Performance Specifications for Instrumentation Systems Designed to Measure Radon Gas in Air).

EPA is seeking comments on the proposed scope for this effort, including the planned approach for including devices. Comments are also welcomed on job titles and scopes that should be included for radon testing and mitigation providers.
