This section oversees the management of residuals, such as septage and wastewater sludge (aka biosolids). There are three main options available for managing these wastes:
• treatment followed by use on the land
Solid Waste Management Rules
Although septage and biosolids are byproducts of wastewater treatment, these wastes are regulated as "Solid Wastes" in Vermont. Please see the Solid Waste Management Rules.
Certifications & Plans
Either approved Sludge Management Plans or Solid Waste Management Certifications are required for all domestic wastewater treatment plants that generate biosolids. Certifications are required for the land application sites where either septage or biosolids are managed. Commercial hauler permits are required for commercial vehicles (with a rated capacity of more than one ton) used to transport these wastes.

Increased Cost for Disposal of Sludge and Septage by Incineration
The state legislature recently amended the law regarding tax on disposed wastes. The modified law now requires the tax to be paid for sludge or septage that is incinerated. The intent of the recent change is to tax disposal options of sludge and septage (landfilling and incineration) and not tax the beneficial use options, such land application and composting.
These guidelines are intended to provide the reader with a summary of the technical elements necessary for proper management of diffuse disposal of sludges and other solid wastes. These wastes can include wastewater treatment plant sludges, septage, wood ash, sludges resulting from the production of paper, and sludges resulting from the treatment of food wastes.
The equation for MATHEMATICAL DEMONSTRATION of TCLP (metals only) has been updated to include FREE LIQUID as well as percent solids. Please follow the instructions and use this updated equation for all mathematical determination of TCLP metals.

Before & After
A site in Londonderry, Vermont in the summer of 1993, before septage was applied. the site has no vegetative cover and soils with low organic matter.
The same site in the summer of 1997 after septage application. The nutrients, organic matter, and increased moisture retention has promoted lush vegetative growth. The soil has reduced erosion potential.
