N.J. Stat. § 13:1E-117
All new solid waste facilities, other than privately-owned, noncommercial, onsite industrial solid waste facilities which do not accept solid waste generated from any other source and solid waste facilities used exclusively for the land disposal of sludge, shall install and use scales to determine the gross and net tare weight of all vehicles disposing of solid waste at these facilities. The registered operator of each new facility shall maintain a monthly record of the weight and vehicle information for the solid waste disposed of at the facility. This information shall be forwarded to the department on a monthly basis and shall be made available by the department for public inspection. For the purposes of this act, a "new solid waste facility" means any solid waste facility for which a registration statement and engineering design has been filed with the department subsequent to the effective date of this act. The department may adopt regulations or guidelines exempting any class of new solid waste facility from this requirement, except that in no case shall the department exempt any facility the total disposal design capacity of which exceeds 100,000 tons of non-liquid solid waste, as computed by the department. All existing solid waste facilities that are identified in an approved district solid waste management plan for operation after January 1, 1985 and which accept in excess of 31,200 tons of non-liquid solid waste annually, as computed by the department, shall install scales within six months of the effective date of this act. Any existing solid waste transfer station, or any solid waste transfer station for which a registration statement and engineering design are filed after the effective date of this act, which accepts less than 31,200 tons of non-liquid solid waste annually, as computed by the department, shall be exempt from the provisions of this act.
