Draft Technical Guidance: Substantive Revision

DEP ID: 385-2207-001. Title: Pennsylvania Sewage Facilities Act Program Guidance; Site Suitability and Alternatives Analysis Guidelines for New Land Development Proposing Onlot Sewage Disposal. Description: The act of July 20, 2017 (P.L. 321, No. 26) (Act 26) amended the Pennsylvania Sewage Facilities Act (Act 537) (35 P.S. §§ 750.1—750.20a) to allow alternate onlot systems to satisfy sewage planning requirements in the establishment of new lots. Act 26 became effective on September 18, 2017. The Department considers a wide range of available onlot sewage system technologies, including emerging technologies, in the Act 537 new land development planning process. The ability to develop land and create new lots is contingent upon the applicability of given onlot sewage system technology to particular site conditions and upon the assurance and availability of adequate operation and maintenance support mechanisms. The existing regulations do not allow for the consideration of alternate systems to establish new lots. The purpose of this guidance is to provide a systematic approach to site suitability determinations and sewage facilities alternatives analysis for the long-term use of onlot sewage systems. This draft guidance clarifies how to incorporate alternate onlot sewage disposal technologies into the Act 537 new land development planning process described in 25 Pa. Code Chapter 71 (relating to administration of Sewage Facilities Planning Program). This guidance covers the onlot sewage planning process in general, not just planning for alternate systems. The guidance was originally published as draft at 48 Pa.B. 1476 (March 10, 2018). After receiving and considering public comments, the guidance was substantially revised. Highlights of the major changes include: updated formatting to improve readability; addition of definitions and an acronym list; removal of the sewage management requirement schedule; removal of the term ''marginal conditions'' and addition of an explanation as to how sites are now either suitable or unsuitable for onlot sewage systems; and dividing the planning process into five steps for new land development proposing onlot sewage systems.
