On March 19, 2022, the Pennsylvania Department of Environmental Protection (PADEP) published a draft technical guidance document entitled “Trenchless Technology Guidance,” PADEP Doc.

Two workgroups were formed out of that settlement to create guidance related to two topics: (1) alternatives analysis and (2) trenchless technology. The draft “Alternatives Analysis Technical Guidance Document” was published for public comment in October 2021. PADEP is currently working to revise the guidance in response to comments. The draft Trenchless Technology Guidance is the second draft guidance to come from these workgroups.
