Current through Register Vol. 39, No. 2, July 15, 2024
(a) In determining the suitability of waters
				  for use as a source of water supply for drinking, culinary, or food processing
				  purposes after approved treatment, the Commission shall consider the physical,
				  chemical, and bacteriological maximum contaminant levels specified by U.S.
				  Environmental Protection Agency regulations adopted pursuant to the Public
				  Health Service Act, 42
				  U.S.C. 201 et seq., as amended by the Safe
				  Drinking Water Act, 42
				  U.S.C. 300(f) et seq. In
				  addition, the Commission shall be guided by the requirements for unfiltered and
				  filtered water supplies and the maximum contaminant levels specified in
				  15A NCAC
				  18C .1100,
				  18C .1200 and
				  18C .1500, which are incorporated
				  by reference including subsequent amendments and editions.
(b) All waters used for water supply purposes
				  or intended for future water supply use shall be classified to the most
				  appropriate water supply classification as determined by the Commission in
				  accordance with Sections .0100 and .0200 of this Subchapter. A more protective
				  water supply classification may be applied to existing water supply watersheds
				  after receipt of a resolution from all local governments having land use
				  jurisdiction within the designated water supply watershed requesting a more
				  protective water supply classification. Requests for reclassification of
				  non-water supply segments and watersheds to a water supply classification shall
				  include submittal to the Commission of resolutions from all local governments
				  having land use jurisdiction within the proposed water supply watershed for
				  which a water supply classification is being requested, provided that the
				  Commission may reclassify waters without the consent of local governments if
				  the Commission deems such reclassifications appropriate and necessary in
				  accordance with Rule .0101 of this Section. Local governments requesting water
				  supply reclassifications shall provide a topographic map (such as a 1:24,000
				  scale USGS map) indicating the normal pool elevation for backwaters of water
				  supply reservoirs, longitude and latitude coordinates of intended water supply
				  intakes, and critical areas and other watershed boundaries as
				  appropriate.
(c) In considering the
				  reclassification of waters for water supply purposes, the Commission shall take
				  into consideration the risks posed by pollutants and the relative proximity,
				  quantity, composition, natural dilution, and diminution of potential sources of
				  pollution.
(d) The water supply
				  watershed protection requirements of Rules .0620 through .0624 of this
				  Subchapter and
				  G.S.
				  143-214.5 that are applicable to State
				  agencies and units of local government with land use authority in water supply
				  watersheds that were classified as such on or before August 3, 1992, shall be
				  effective no later than:
(1) August 3, 1992 -
				  Activities administered by the State of North Carolina, such as the issuance of
				  permits for landfills, NPDES wastewater discharges, and land application of
				  sludge/residuals, and road construction activities;
(2) July 1, 1993 - Municipalities with a
				  population greater than 5,000;
(3)
				  October 1, 1993 - Municipalities with a population less than 5,000;
				  and
(4) January 1, 1994 - County
				  governments and other units of local government, as applicable.
