The department may consolidate and combine two or more of the water supply permits of a public water supply system existing as of February 15, 2012 into one comprehensive water withdrawal permit that encompasses the provisions, terms and conditions of the existing permits and renders such provisions, terms and conditions consistent with each other. The department may require submission of a permit application under this Part in connection with such a consolidation if the department determines that such consolidation is necessary to protect the environment and the public health, safety and welfare and to ensure the proper management of the waters of the State.
