(1) 
Nuisance. The following shall not be considered a nuisance: mineral resource extraction and processing activities, operations (except between 7:00 p.m. and 7:00 a.m. and on weekends), facilities or appurtenances thereof, conducted or maintained for commercial mineral resource extraction and processing purposes on land designated as mineral resource land (MRL), regardless of past or future changes in the surrounding area land use or land use designation.
(2) 
Disclosure. The disclosure statement in subsection (2)(b) of this section shall be used under the following circumstances and in the following manner:
(a) 
Approval of any land division, land use, building, or development of lands adjacent to or within 500 feet of lands designated as mineral resource land (MRL) shall be conditioned on the execution by the applicant of a statement of acknowledgment containing the disclosure statement on forms provided by the department of community development. However, if a disclosure conforming to the provisions of this section has been provided for a prior permit, subsequent disclosures shall not be required.
(b) 
The required disclosure statement is as follows:
If your real property is within five hundred (500) feet of real property within an area designated as Mineral Resource Land (MRL), you may be subject to inconveniences or discomforts arising from such operations, including but not limited to noise, tree removal, odors, fumes, dust, smoke, the operation of machinery, and the storage and disposal of aggregate products. One or more of the inconveniences described may occur as a result of extraction and processing operations which are in conformance with existing laws and regulations. Jefferson County has determined that the use of certain real properties for mineral resource extraction and processing activities is necessary to ensure resource availability in the County. The County will not consider to be a nuisance those inconveniences or discomforts arising from extraction and processing operations, if such operations are consistent with commonly accepted best management practices and comply with local, state, and federal laws.
