In addition to any other requirements in law, or any rule or regulation adopted pursuant thereto, whenever a water purveyor is issued, pursuant to section 10 of P.L. 1977, c.224 (C.58:12A-10), three notices of violation for any reason or two notices of violation related to an exceedance of a maximum contaminant level within any 12-month period, the water purveyor, within 60 days after receipt of the third or second notice, as applicable, shall submit to the department a mitigation plan specifying whether the notice of violation will be addressed through operational changes or require a capital expenditure and providing a schedule for implementation of the mitigation plan. The mitigation plan shall include a report prepared by the licensed operator of the public community water system and a professional engineer licensed pursuant to P.L. 1938, c.342 (C.45:8-27 et seq.) that includes a technical analysis of the notices of violation and an explanation of how the mitigation plan submitted pursuant to this section is intended to prevent a recurrence of the issue that resulted in the notice of violation.
