(c) The owner of an inactive hazardous waste disposal site, and/or any person responsible for implementing the remedial program at such site where institutional or engineering controls are employed pursuant to this title shall, unless otherwise provided in writing by the department, annually submit to the department a written statement by an individual licensed or otherwise authorized in accordance with article one hundred forty-five of the education law to practice the profession of engineering, or by such other expert as the department may find acceptable certifying under penalty of perjury that the institutional controls and/or engineering controls employed at such site are unchanged from the previous certification and that nothing has occurred that would impair the ability of such control to protect the public health and environment, or constitute a violation or failure to comply with any operation and maintenance plan for such controls and giving access to such real property to evaluate continued maintenance of such controls.
