            .S.  EPA Radon Contractor Proficiency Program
                           PROGRAM OVERVIEW

                                    INTRODUCTION

    In late 1988, Congress enacted the Indoor Radon Abatement Act (IRAA), which established a long-term
national goal of reducing indoor radon levels to equal levels outdoors.  The law also requires EPA to establish
regional radon training centers, develop a voluntary contractor proficiency program, and provide information
an capable radon reduction contractors to States and the public.

    The primary objective of the Agency's efforts to address the indoor radon problem is to reduce human
exposure to radon and thereby reduce the risk of lung cancer.  EPA views the achievement of these objectives
is a cooperative effort, involving Federal agencies, State governments, institutions of higher education, and an
active private sector. The Agency wants to assist in the development of State and private sector expertise, so
Jie public can readily locate competent services to mitigate radon hazards in existing structures and prevent
radon problems in new construction.

    This booklet will provide you with information about EPA's Radon Contractor Proficiency Program and
low to enter the Program, if you choose to participate. Please read this booklet carefully so you understand the
Program requirements.

                               PROGRAM ELEMENTS

    EPA established the Radon Contractor Proficiency (RCP) Program in 1989 to evaluate the proficiency of
•adon mitigators of residential homes and provide information to the public on proficient mitigators. The RCP
Program is a voluntary program consisting of several elements that help collectively to ensure the proficiency
of radon mitigation contractors, and the quality of mitigation services offered to the public. These program
dements are  1) training, 2) the Exam, 3) the proficiency report, 4) interim radon mitigation standards, and 5)
)ienmal re-examination.

                                       1.  TRAINING

    EPA requires all participants in the RCP Program to complete at least two days of EPA-approved, hands-
on training. Only EPA-approvcd training will be recognized. You must complete this training before you take
ihe RCP Program National Radon Proficiency Exam.  Approved training is offered by EPA's Regional Radon
Training Centers (RRTCs), States, and private providers. See the insert for a list of approved courses and course
providers.

    While only two days of hands-on training arc required, EPA recommends that you take at least four days
of training if you have not had otherradon mitigation training. The Agency has developed a comprehensive four-
day training program, Radon Technology for Mitigators (RTM), offered by the RRTCs, that satisfies the hands-
on training requirement.  The course consists of two days of classroom  instruction and two days of hands-on,
practical application.  Included arc practical instruction in radon diagnostics,  system design, equipment and
materials selection, and system installation and evaluation.  The course uses lectures, videos, and student

-------
activities that provide experience in the basic skills and knowledge necessary for proper radon mitigation in
homes. This four-day course assumes some prior knowledge of radon and radon mitigation fundamentals. If
you have not had radon training prior to entering the RTM course, you should obtain and review publications
listed on Page 7 prior to entering the course.  EPA recommends starting with publications B2, B3, and A4 (see
Page 7).

     There are four EPA Regional Radon Training Centers (RRTCs):
    Southern Regional Radon Training Center
    Auburn University (Lead Center),
    Louisville, University of Tulsa
    Texas A&M

    EPA strongly recommends annual continuing education for all radon mitigators to improve mitigation
skills, increase knowledge, improve business capabilities, and keep current with new developments in the field.
Over a two-year period, a mitigator should devote 16 hours to coursework, conferences, symposia, workshops,
seminars, or other radon related continuing education. Recommended topics for continuing education include
1) new technology/developments, 2) HVACs and radon mitigation, 3) radon in schools and large buildings, 4)
strategies for hard-to-mitigate houses, 5) better  business administration, 6) worker health and safety, 7)
advanced diagnostics, 8) troubleshooting mitigation systems, and 9) epidemiology and radon risk analysis.
    Approved training courses offered by the RRTCs, States, and private training providers are generally scheduled
 in advance of Exam dates. To register for training, contact one of the approved training providers.
                                        2. THE EXAM

              The RCP Program National Radon Proficiency Exam (the Exam) is a comprehensive test
covering six (6) major domains of mitigation practice:
  1)   evaluation of measurement history;
  2)   diagnosis of problem;
  3)   selection of strategy and design of
       mitigation plan;
4)   implementation of strategy;
5)   evaluation of mitigation systems; and
6)   professional standards of conduct and
     ethics.
    The Exam consists of 150 multiple choice questions, and three and one-half hours are allowed for its
completion.  The Exam has been structured to cover all  aspects of radon mitigation.  A list of criteria  for
evaluation of radon knowledge and three sample questions are provided below (see Preparing for the Exam).
                                              -2-

-------
You should have a thorough understanding of these subject areas. Preparing for the Exam also contains a list
of pertinent publications you may wish to acquire or reference.

    The Exam can only be taken after you have completed the required training. Upon passing the Exam and
meeting all program requirements, your name will be added to the RCP Program Proficiency Report, and you
will be issued a RCP Program identification card, valid for two years.

    The Exam is given at the four Regional Radon Training Centers and their satellite locations on a periodic
basis, generally following a monthly schedule. State governments also administer the Exam on National Exam
Dates, which are noted in the insert. Please consult the insert as you complete Section V of your application
(Selection of Exam Date).

    When you arrive to take the Exam, you must present a photo ID (driver's license orpassport) to gainentrance.
You must also give the Exam proctor two 2" x 2" (passport size) photos of yourself. These photos will be used
to produce an identification card which will be sent to you once you have met the program requirements.

    Once your test has been scored, you will be informed by letter of your performance.  If you fail the Exam,
you may re-take the Exam at any other scheduled time.

                               3.  THE PROFICIENCY REPORT

    After successfully completing the Program requirements, you will be listed in the National RCP Program
Proficiency Report.  The Proficiency  Report is issued to States, EPA Regional Offices, and public health
organizations. The Report will be used to refer the public to you. An individual's name appearing in this Report
may also serve other functions; for example, a number of States have developed, or are developing, certification
programs for mitigation contractors. A requirement for State certification may include successful completion
of the RCP Program.

    An individual listed in the Report has met the requirements of the RCP Program and has demonstrated a
minimum level of radon mitigation capability. An individual whose name appears in the Proficiency Reportmay
notmisrepresentthe meaning of RCP Program participation to the public. Being listed in the Proficiency Report
means that you (not  your company) have met the requirements of the Program and have demonstrated an
understanding of radon and radon reduction methods.  The RCP Program  does not accredit mitigation
contractors, nor does it certify, recommend, or endorse participating individuals; however, it does approve radon
mitigators. Below are suggested phrases appropriate for advertising:

       [Individual's name] meets EPA requirements for radon mitigation.
    •   [Individual's name] is an EPA-approved radon mitigator.

       EPA may determine that a mitigator's actions or performance warrant removal from the Proficiency
Report. A mitigator can be removed from the Report for failing to comply with Program requirements or for
submitting false or misleading information.

                    4. INTERIM RADON MITIGATION STANDARDS

    As a participant in the RCP Program, you will be required to follow EPA Radon Mitigation Standards when
you perform radon mitigation work (see Interim Radon Mitigation Standards). If you do not adhere to  these
Standards, you will be subject to being delisted from the RCP Program and the Proficiency Report. Final radon
mitigation standards are under development and will replace the Interim Standards. You will be required to
adhere to the final standards when they become available.
                                             -3-

-------
    The Mitigation Standards set a base level of performance for all RCP Program participants. The Standards
require mitigators to follow specific practices related to radon mitigation.  They cover such areas as code
compliance, installation standards, and pre- and post-mitigation radon measurements.

                             5. BIENNIAL RE-EXAMINATION

       To ensure that RCP Program participants stay abreast of changes in the radon mitigation field, all
contractors listed in the Report must be re-examined every two years. The re-exam is similar to the first Exam
(see Preparing for the Exam), but includes new technology, policy standards, protocols, and other develop-
ments. You should apply for and take the re-exam prior to the expiration date on your ID card. No training is
required prior to taking your biennial re-examination, however, EPA strongly encourages continuing education
on an annual basis to prepare for the re-exam and for your professional development.

        INTERIM RADON MITIGATION STANDARDS
                                    December 15,1991
       This document outlines basic minimum performance standards for participants in the Radon
Contractor Proficiency (RCP) Program involved in the reduction of radon in buildings. The purpose of
Jiese standards is to help ensure the protection of the general public from the risk of elevated indoor
radon.  State and local regulatory agencies may choose to expand and use these standards in assessing
performance of professionals involved in radon mitigation.  While this document outlines minimum
requirements for participation in the voluntary Federal program, there may be other practices necessary to
achieve quality radon mitigation installations. Radon mitigation contractors agree to follow these stan-
dards as a condition for inclusion in the U.S. Environmental Protection Agency (EPA) National Radon
Contractor Proficiency Report, and as a condition for EPA approval. Failure to comply with these
standards may result in loss of EPA approval and the contractor's name being removed from the RCP
Program Proficiency Report.

       This document replaces the RCP Program Radon Mitigation Guidelines issued in October 1989.
The Standards incorporate revisions intended to clarify required practices of RCP Program listed contrac-
tors.  RCP contractors are not required to retrofit work performed prior to December 15,1991, as relates
to these mandatory practices. The word "shall"  is highlighted and used to indicate practices that are
mandatory for program participants. At a later date the Agency may supersede these Interim Standards
by issuing final Radon Mitigation Standards which will establish more definitive specifications for the
installation of radon mitigation systems.

       For further questions concerning these Interim Mitigation Standards, please call your EPA
Regional Office. For extra copies of these Standards, please call your nearest Regional Radon Training
Center (see page 12).

Definition:  "mitigator", "contractor" - the individual approved and listed in the RCP Program.
1.0 INITIAL CLIENT INTERVIEW - RADON MEASUREMENTS

       The mitigator shall review and assess the quality of any previous radon measurements made by
the client and ascertain whether or not these measurements were made in accordance with EPA "Indoor
Radon and Radon Decay Product Measurement Protocols" (EPA 520-1/89-009), "Interim Protocols for
Screening and Follow-up Radon and Radon Decay Product Measurements" (EPA 520/1-86-014-1), or
subsequent revisions or additions to these documents. If the contractor determines that the procedures
outlined in these documents were not followed, the contractor shall advise the client of this and retesting
shall be recommended.
                                          -9-

-------
2.0 BUILDING INVESTIGATION

        The contractor shall conduct a visual inspection prior to the initiation of any installation activities
to assist in designing the most effective mitigation system.
3.0 TEMPORARY RISK REDUCTION MEASURES

3.1 In dwellings with elevated radon levels, the mitigator shall advise the client whether or not temporary
measures should be used to reduce occupant exposure until a permanent mitigation system can be in-
stalled. This could include temporary measures such as natural ventilation, or mechanical ventilation with
unconditioned outside air, or limiting the occupants' exposure by minimizing the time spent in areas of the
home with elevated radon levels, or any measures which effectively minimize occupant exposure.

3.2 The contractor shall not install a temporary radon reduction system in lieu of a permanent mitigation
system.

3.3 Temporary radon reduction systems shall be labeled as such. The notice shall be legible at a distance
of two feet, and contain wording stating that the system should 1) not be removed until a permanent
mitigation system can be installed, and 2) the permanent mitigation system should be installed within 30
days after the installation date of the temporary system. The label shall also contain the contractor's
name, phone number, and the installation date. If the equipment is not easily labeled, the notice shall be
posted on the electric service panel or other prominent location.
4.0 CLIENT INFORMATION

       The contractor shall provide the following information to the client prior to initiating any work:

            1.   the contractor's RCP Program identification number,
           2.   the scope of the work to be completed;
           3.   a statement indicating any known hazards associated with chemicals used in or as part of
               the installation;
           4.   a statement indicating compliance with and implementation of all EPA standards and
               those of other agencies having jurisdiction (e.g., code requirements);
           5.   a statement indicating any required maintenance by the homeowner; and
           6.   an estimate of the installation cost and annual operating cost of the system.


5.0 MITIGATION SYSTEM INSTALLATION

5.1 The mitigation system shall be installed as a permanent, integral part of a building.

5.2 The mitigator shall comply with all laws, ordinances, local building codes, applicable Occupational
Safety and Health Administration (OSHA) standards, or regulations of all Authorities having jurisdiction.
The mitigator shall obtain all licenses and permits required for the work. Examples of these include
proper contractor licenses and building permits.  In cases where discrepancies occur between these
Mitigation Standards and applicable laws, ordinances, local building codes or regulations, the appropriate
laws take precedence.  Where such deviations from the Mitigation Standards are required by law, they
shall be reported to the EPA Regional office within 30 days after completion of work.	

                                              -10-

-------
;5.3 Material Safety Data Sheets (MSDS) for sealers, compounds, adhesives. paints, and other materials
uhall be provided to workers and also made available to clients upon request.  The contractor shall review
with the occupants or their representative all materials to be used in the installation of the mitigation
system and notify them if the MSDS indicates the possibility for adverse reactions in sensitive people.

5.4 Each active radon mitigation system shall have a mechanism to monitor system performance. The
mechanism shall be plainly visible and simple to read or interpret.

5.5 All visible portions of mitigation systems shall be labeled (including the system power or disconnect
switch) to identify their function. One central label shall be placed on the mitigation system, electric
panel, or other prominent location; be legible from a distance of at least two feet; and  include a system
description, a contact name and phone number.

5.6 Depressurization system fans (i.e., sub-slab, sub-membrane, block wall and drain tile depressuriza-
tion systems) shall not be installed in the conditioned (heated/cooled) space of a building, or in any
basement, crawlspace, or other interior location directly beneath conditioned space of a building.  Appro-
priate places for depressurization system fans include attics not suitable for habitation, garages, or the
exterior of the building.

5.7 To ensure against re-entrainment of radon back into the building and direct exposure to people,
exhaust vents from depressurization system fans and radon-in-water aeration systems shall be discharged
according to all of the following requirements:  1) the discharge point shall be ten feet or more above
ground level; 2) the discharge point shall be ten feet or more, measured directly (line-of-sight) from any
window, door, or other openings in the structure (e.g., vents, operable skylights or air intakes) that are less
than two feet below the exhaust point; 3) the discharge point shall be ten feet or more away from any
private or public access; and 4) the discharge point shall be ten feet or more from any opening into an
adjacent building.
6.0 POST-MITIGATION TESTING

       The contractor shall ensure that a confirmatory short-term screening measurement is made no
sooner than 24 hours, nor longer than 30 days after completion and start-up of the mitigation system. The
contractor shall recommend that the client obtain an independent radon measurement. The contractor is
not required to make a confirmatory radon measurement if he/she can obtain a copy of the test report from
a client's or independent third party's test. The contractor shall recommend retesting at least every two
years.  All measurements shall be conducted in accordance with EPA protocols as cited in" Interim
Protocols For Screening and Follow-up Radon and Radon Decay Product Measurements" (EPA 520/1 -86-
014-1) and "Indoor Radon and Radon Decay Product Measurement Protocols" (EPA 520-1-89-010), or
subsequent revisions or additions to these documents.
7.0 WORKER SAFETY

       Contractors shall comply with all applicable OSHA standards relating to worker safety and
occupational radon exposure. Please reference the following standards in the Code of Federal Regula-
tions: OSHA "Safety and Health Regulations for Construction," 29 CFR 1926, and OSHA "Occupational
Safety and Health Regulations," 29 CFR 1910.
