Rates and Regulatory Matters	Rates and Regulatory Matters The State Corporation Commission of Virginia (“SCC”) exercises regulatory authority over the natural gas operations of Roanoke Gas. Such regulation encompasses terms, conditions, and rates to be charged to customers for natural gas service; safety standards; extension of service; and accounting and depreciation. On June 30, 2017, the Company filed with the SCC its SAVE (Steps to Advance Virginia's Energy) Plan and Rider application.
