Sec. 1. 12 MRSA §685-A, sub-§5, as amended by PL 1999, c. 530, §8, is further amended to read:

5. Considerations, application and exemptions. A land use standard may not deprive an owner or lessee or subsequent owner or lessee of any interest in real estate of the use to which it is lawfully devoted at the time of adoption of that standard. Year-round and seasonal single residences and operating farms in existence and use as of September 23, 1971, while so used, and new accessory buildings or structures or renovations of the buildings or structures that are or may be necessary to the satisfactory and comfortable continuation of these residential and farm uses are exempt from the requirements of section 685-B, subsection 1.

Land use standards adopted pursuant to this chapter for management districts may not limit the right, method or manner of cutting or removing timber or crops, the construction and maintenance of hauling roads, the operation of machinery or the erection of buildings and other structures used primarily for agricultural or commercial forest product purposes, including tree farms. Notwithstanding this subsection, a permit from the commission is required for roads covering a ground area of 3 acres or more constructed in management districts, unless those roads are constructed and maintained in accordance with the guidelines of the commission's Land Use Handbook, Section 6, "Erosion Control on Logging Jobs," or as revised. The commission may require a person constructing a road to notify the commission of the location of the road within 21 days.

Land use standards adopted pursuant to this chapter must establish a minimum setback of 100 feet for all structures within a commercial sporting camp complex that are constructed solely for the housing of guests, including structures within a main sporting camp complex and an outpost camp. The standards must establish a minimum setback of 150 feet for all other structures within a sporting camp complex, including, but not limited to, a main lodge, a dining area, a workshop and a parking area.

In adopting district boundaries and land use standards, the commission shall give consideration to public and private planning reports and other data available to it, and shall give weight to existing uses of land and to any reasonable plan of its owner as to its future use.

A permit from the commission is not required for the repair or maintenance of county-owned roads, bridges or culverts as long as
