Final TGD: New Guidance

DEP ID: 310-2100-003. Title: Trenchless Technology Guidance. Description: This guidance: outlines the steps and options to consider, and implement as appropriate, when proposing to use a trenchless technology installation method on any portion of a project; has been prepared to provide information to project proponents that may help to prevent environmental issues, improve project planning, permitting and compliance with applicable regulatory requirements; establishes a common, complete and consistent level of understanding of the information the Department may request to adequately review permit applications proposing trenchless technology; was drafted in concurrence with the existing regulations. Trenchless technology use is not specifically referenced in any Department regulation; however, the environmental issues that can result from unplanned failures of this construction method can have regulatory implications. This guidance provides specific recommendations to meet relevant Department regulations for this construction methodology and to anticipate, monitor for and respond to failures in a manner that avoids, minimizes and mitigates environmental issues that may arise during construction.

 This final TGD was revised as a result of comments received on the draft TGD published at 52 Pa.B. 1693 (March 19, 2022), then entitled Trenchless Technology Guidance. Based on 143 comments received from 150 commentators during the 60-day public comment period on the draft TGD, the Department made several editorial and substantive changes to the final TGD. These changes included many clarifying edits including when it is appropriate to use a Pennsylvania-licensed professional engineer or professional geologist, or both; addition of mont- morillonite to the recommended analyte list; removal of the horizontal directional drilling flow chart to clear up ambiguity and for consistency with the rest of the document; addition of new risk factors to more accurately assess risk; and updates to definitions. The comment and response document accompanying this final TGD responds to all comments received on the draft TGD.

Contact: Questions regarding this TGD can be directed to Andy Klinger, Bureau Director, Bureau of Waterways Engineering and Wetlands, at (717) 772-5975 or
