49-112.  County regulation;  standards A. When authorized by law,  a county may adopt a rule,  ordinance or regulation that is more stringent than or in addition to a provision of this title or rule adopted by the director or any board or commission authorized to adopt rules pursuant to this title if all of the following requirements are met: 1. The rule,  ordinance or regulation is necessary to address a peculiar local condition. 2. There is credible evidence that the rule,  ordinance or regulation is either: (a) Necessary to prevent a significant threat to public health or the environment that results from a peculiar local condition and is technically and economically feasible. (b) Required under a federal statute or regulation,  or authorized pursuant to an intergovernmental agreement with the federal government to enforce federal statutes or regulations if the county rule,  ordinance or regulation is equivalent to federal statutes or regulations. 3. Any fee or tax adopted under the rule,  ordinance or regulation does not exceed the reasonable costs of the county to issue and administer the permit or plan approval program. B. When authorized by law,  a county may adopt rules,  ordinances or regulations in lieu of a state program that are as stringent as a provision of this title or rule adopted by the director or any board or commission authorized to adopt rules pursuant to this title if the county demonstrates that the cost of obtaining permits or other approvals from the county will approximately equal or be less than the fee or cost of obtaining similar permits or approvals under this title or any rule adopted pursuant to this title. If the state has not adopted a fee or tax for similar permits or approvals,  the county may adopt a fee when authorized by law in the rule,  ordinance or regulation that does not exceed the reasonable costs of the county to issue and administer that permit or plan approval program. C. A county that adopts rules,  ordinances or regulations pursuant to subsection B of this section and that at any time cannot comply with subsection B of this section shall prepare and file a notice of noncompliance with the director. The county shall post a copy of the notice of noncompliance on the county's website with a date stamp of the date of posting. If the county does not comply with subsection B of this section within one year after posting of the notice on the county's website,  the director shall provide written notice to and assert regulatory jurisdiction over those persons and entities subject to the affected county rules,  ordinances or regulations. D. Except as provided in chapter 3,  article 3 of this title,  before adopting or enforcing any rule,  ordinance or regulation pursuant to subsection A or B of this section,  the county shall comply with the following requirements: 1. Prepare a notice of proposed rulemaking to include the proposed rule,  ordinance or regulation. This notice shall demonstrate evidence of compliance with subsection A or B of this section. The notice shall include the name,  address and phone number of a person who can answer questions about the proposed rule,  ordinance or regulation and accept any written requests for the county to conduct an oral proceeding. The county shall post the notice on the county's website with a date stamp of the date of posting. The county shall publish the availability of the notice of the proposed rule,  ordinance or regulation in a newspaper of general circulation in the county. If there is no newspaper of general circulation in the county,  the county shall publish the notice in a newspaper of general circulation in an adjoining county. If requested by the public,  the county shall make available a paper copy of the notice at a reasonable cost. 2. For at least thirty days after the posting of the notice of the proposed rule,  ordinance or regulation,  afford persons the opportunity to submit in writing comments,  statements,  arguments,  data and views on the proposed rule,  ordinance or regulation.  3. Respond in writing to the comments submitted pursuant to paragraph 2 of this subsection and post the county's response on the county's website. If requested by the public,  the county shall make paper copies of its comments available at a reasonable cost.  4. Schedule a public hearing on the proposed rule,  ordinance or regulation if a written request for an oral proceeding is submitted to the county during the thirty-day comment period. The county shall post the notice of oral proceeding on a proposed rule,  ordinance or regulation on the county's website. The county shall post the notice of oral proceeding at least twenty days before the date of the oral proceeding. The county shall publish notice of any public hearing required pursuant to this paragraph in any newspaper as prescribed by this title or county ordinance. The county shall select a time and location for the public hearing that affords a reasonable opportunity for the public to participate. E. A county is not required to comply with subsection D,  paragraphs 2,  3 and 4 of this section before it adopts or enforces a rule,  ordinance or regulation if the rule,  ordinance or regulation only incorporates by reference an existing state or federal rule or law that provides greater regulatory flexibility for regulated parties and otherwise satisfies the requirements prescribed in subsection B of this section. F. Until June 30,  1995,  a person may file with the clerk of the board of supervisors for that county a petition challenging a county rule,  ordinance or regulation adopted before July 15,  1994 for compliance with the criteria set forth in subsection A or B of this section. The petition shall contain the grounds for challenging the specific county rule,  ordinance or regulation. Within one year after the petition is filed,  the board of supervisors shall review the challenged rule,  ordinance or regulation and make a written demonstration of compliance with the criteria set forth in subsection A or B of this section and challenged in the petition. Any rules,  ordinances or regulations that have been challenged and for which the board of supervisors has not made the written demonstration within one year after the filing of the petition required by this section become unenforceable as of that date. If a county has already made a written demonstration under section 49-479,  subsection C,  for a rule,  ordinance or regulation,  the person filing the petition shall state the specific grounds in the petition why that demonstration does not meet the requirements of this section. G. A rule,  ordinance or regulation adopted pursuant to subsection A of this section may not be invalidated subsequent to its adoption on the grounds that the economic feasibility analysis is insufficient or inaccurate if a county makes a good faith effort to comply with the economic feasibility requirement of subsection A,  paragraph 2,  subdivision (a),  of this section and has explained in the written statement,  made public pursuant to subsection D of this section,  the methodology used to satisfy the economic feasibility requirement. H. This section shall not apply to any rule,  ordinance or regulation adopted by a county pursuant to: 1. Title 36 for which the state has similar statutory or rule making authority in this title. 2. Section 49-391. 3. Chapter 3,  article 8 of this title. 4. Chapter 4,  article 3 of this title and section 49-765. 5. Nonsubstantive rules relating to the application process that have a de minimis economic effect on regulated parties.
