Final TGD: Substantive Revision

 DEP ID: 294-2309-002. Title: Pennsylvania Radon Mitigation Standards. Description: The Pennsylvania Radon Mitigation Standards (PA RMS) detail how radon mitigators can install mitigation systems that conform to the regulatory requirements in 25 Pa. Code Chapter 240 (relating to radon certification). These standards were first published in 1997. Since that time, additional field experience has been gained and additional National radon mitigation standards have been published. These changes prompted a revision of the PA RMS, including the following revisions and additions: changing configurations to avoid condensation around fans; suggested sealants and materials that are not permitted as sealants; active sub-slab depressurization systems can be exhausted at ground level instead of the current roofline level; new electrical information was obtained for low-voltage and direct-current fan use; recommended materials for exterior pipe vents; and the recommendation to consider use of an active radon warning device on the active sub-slab depressurization piping in addition to the U-tube manometer.

 This TGD was published as a draft at 52 Pa.B. 6784 (October 29, 2022). The Department received no comments on the draft TGD. The final TGD is identical to the draft TGD, except for correction of reference errors.

 Contact: Questions regarding this TGD can be directed to Robert Lewis at rolewis@pa.gov or (717) 783-9485.

 Effective Date: March 4, 2023
