The following projects are not considered construction of a large electric power generating plant or high voltage transmission line and may be constructed without a permit from the commission:
equipment additions at an existing substation that do not require expansion of the land needed for the substation and do not involve an increase in the voltage or changes in the location of existing transmission lines, except that up to the first five transmission line structures outside the substation may be moved to accommodate the equipment additions provided the structures are not moved more than 500 feet from the existing right-of-way;
high voltage transmission lines:
maintenance or repair of a high voltage transmission line within an existing right-of-way;
reconductoring or reconstruction of a high voltage transmission line with no change in voltage and no change in right-of-way, provided that any new structures that are installed are not designed for and capable of operation at higher voltage; or
relocation of a high voltage transmission line that is required by a local or state agency as part of road, street, or highway construction; or
large electric power generating plants:
maintenance or repair of a large electric power generating plant;
modification of a large electric power generating plant to increase efficiency as long as the capacity of the plant is not increased more than ten percent or more than 100 megawatts, whichever is greater, and the modification does not require expansion of the plant beyond the developed portion of the plant site. If a subsequent modification results in a total of more than 100 megawatts of additional capacity, this provision does not apply. An increase in efficiency is a reduction in the amount of Btu's (British Thermal Units) required to produce a kilowatt hour of electricity at the facility;
refurbishment of a large electric power generating plant that does not expand the capacity of the plant or expand the plant beyond the developed portion of the plant site and the refurbishment does not require a certificate of need from the public utilities commission;
conversion of the fuel source of a large electric power generating plant to natural gas, as long as the plant is not expanded beyond the developed portion of the plant site; or
start-up of an existing large electric power generating plant that has been closed for any period of time at no more than its previous capacity rating and in a manner that does not involve a change in the fuel or an expansion of the developed portion of the plant site.
In the event a modification or other change in an existing substation, high voltage transmission line, or large electric power generating plant does not qualify for an exception under this part, the modification or change may qualify for a minor alteration under part 7850.4800.
Any person proposing to move transmission line structures under subpart 1, item A, or to reconductor or reconstruct a high voltage transmission line under subpart 1, item B, subitem (2), or to implement changes to a large electric power generating plant under subpart 1, item C, subitem (2), (3), (4), or (5), must notify the commission in writing at least 30 days before commencing construction on the modification or change.
