N.J. Admin. Code § 7:26A-9.9
The Department may, in addition to any other civil administrative penalty assessed pursuant to this subchapter, include as a civil administrative penalty the economic benefit (in dollars) that the violator has realized as a result of not complying with, or by delaying compliance with, the requirements of the Act, or any rule promulgated, any administrative order, permit, license or other operating authority issued, any district solid waste management plan approved pursuant to the Act. If the total economic benefit was derived from more than one violation, the total economic benefit may be apportioned among the violations from which it was derived so as to increase each civil administrative penalty assessment to an amount no greater than $ 50,000 per violation.
