Re: Sludge Management Plan for Arbor Hill MHP
Sludge is wasted from one of the facility's sludge return lines into the sludge holding
tank. When the contents of the sludge holding tank is adequately thickened, lime is
added to the sludge in sufficient quantity to meet the State's lime stabilization criteria and
Granville Farms removes the sludge and land applies it per their permitted parameters.
Please let me know if any additional information is needed.
