PA DEP has published a new draft technical guidance document in the PA Bulletin which would make substantive revisions to the SEO certification process. You can view the draft guidance document in the Department’s eLibrary HERE.

This guidance document provides a framework for the Department’s SEO certification and training program with the goal of producing a knowledgeable and skilled SEO community to help administer the onlot sewage program in this Commonwealth. The program includes the criteria for SEO candidates who wish to become certified SEOs, the criteria for certified SEOs to maintain their SEO certification, and the criteria for lapsed or inactive SEOs who wish to reinstate their SEO certification.

Major revisions to this document are now being proposed to include the following: update of contact information; incorporation of a new learning management system with an explanation of how it will affect the SEO community; change the current static 2-year certification cycle to a rolling 2-year certification cycle; phase out the opportunity to roll over seven continuing education credits into the next cycle to zero roll-over credits effective June 30, 2022; reinstate a requisite soils course as a prerequisite for the SEO certification exam; and completion of the requisite soil course by all current SEOs who have never completed a Department-approved soils course within 5 years of the proposed guidance becoming final.

Interested persons may submit written comments on this draft technical guidance document through Monday, July 1, 2019. Comments submitted by facsimile will not be accepted. All comments, including comments submitted by e-mail must include the commentator’s name and address.
