PADEP Proposes Antidegradation Standard for On-lot Septic Systems

PADEP Proposes antidegradation for On-lot septic systems -Sewage Facilities Planning Module Review for Onlot Sewage Systems Proposed in High Quality and Exceptional Value Watersheds – Proposed Policy – 385-2208-XXX.

POLICY: The Department will assure that cost-effective and reasonable best management practices (BMPs) for nonpoint source control are achieved to maintain and protect water quality when reviewing sewage facilities planning modules for proposed individual or community onlot sewage systems in high quality and exceptional value watersheds.

PURPOSE: The purpose of this guidance is to describe BMPs for individual and community onlot sewage systems that can achieve nonpoint source control in High Quality and Exceptional Value waters, and to provide a process to select appropriate BMPs to achieve such control.

Problem
1. Implementation – Policy says it applies to only new systems or permits, this will therefore include all existing lots not developed.  The policy also suggests it should be used for all repairs.
2. Cost to Implement- Could add up to cost of installing and maintaining septic systems in PA.
3. PADEP says the problem is because of nitrate. The only problem is that nitrates are not a problem in PA and the nitrate loading from septic systems to the stream may be only 4%.  The major sources fossil fuels, atmospheric deposition, agricultural runoff, urban runoff, and wastewater treatment plants.
