a thickness not to exceed 12 -inches on at least 20,000 sq. ft. of land at the disposal
site.
4. The facilities shall be effectively maintained and operated as a non -discharge system
to prevent the discharge of any wastewater resulting from the operation of this

layer. To provide maximum benefits, fertilization should occur no sooner than 15
days nor later than 30 days subsequent to disposal.
