Get to the Bottom of BAT Septic Systems at #MACoCon

Get an update on the pending best available nitrogen removal technology (BAT) septic system regulations and learn what important factors county officials need to keep in mind about them at the 2016 MACo Winter Conference.

BATter Up! Understanding the BAT Septic System Issue


In 2012, the Maryland Department of the Environment (MDE) adopted regulations mandating the use of BAT – Best Available nitrogen removal Technology – septic systems outside of a critical area. The mandate prompted concerns from MACo and numerous other stakeholders about effectiveness and cost. In response to those concerns, Governor Hogan and MDE have proposed regulations to repeal the BAT mandate. Panelists will provide an overview of the regulations, the science and policy issues related to BAT septic systems, and key stakeholder perspectives.
