Who Is Required to Become DEP Certified
DEP Radon certification has been required by Pennsylvania state regulation since September 21, 1988. Radon certification must be obtained before any person conducts radon testing, radon mitigation, or radon laboratory analysis in Pennsylvania, with the exception of the few exceptions listed below:
- Testing for or mitigating against radon contamination in a building that the person owns or occupies.
- Using measures designed to prevent radon contamination in newly constructed buildings. This exception does not apply to radon testing or installation of radon mitigating devices in these buildings following occupancy.
- Performing testing or mitigation in the course of the person's normal duties as an employee or contractor of DEP or the federal government.
- Performing scientific research if the person discloses the information obtained to the DEP (relating to reporting of information) and the person informs the owner or occupant of the affected building of the following:
- That the person in not certified by the Department to test or mitigate against radon contamination.
- That the test results are not certified.
- That the mitigation methods are for experimental purposes and may be unsuccessful.
- Purveying, but not placing or retrieving passive radon testing devices, such as charcoal canisters or track etch monitors supplied by a certified laboratory, if radon concentrations determined are reported directly to the owner or occupier of the building tested.
Unless you meet one of the above listed exemptions, you are required to become DEP-certified prior to performing radon testing, mitigation and/or laboratory analysis in Pennsylvania. Membership in professional organizations, such as NRSB or NEHA, does not exempt you from this certification requirement.
