Nevada Administrative Code › Chapter 445A - Water Controls › WATER POLLUTION CONTROL › Standards for Water Quality › Section 445A.1239 - Control points: Prescription and applicability of numerical standards for water quality; designation of beneficial uses

Current through June 11, 2024
1. Control points are locations where water
				quality criteria are specified. Criteria so specified apply to all surface
				waters of Nevada in the watershed upstream from the control point or to the
				next upstream control point or to the next water named in NAC 445A.123 to
				445A.2234, inclusive.
2. If there
				are no control points downstream from a particular control point, the criteria
				for that control point also apply to all surface waters of Nevada in the
				watershed downstream of the control point or to the next water named in NAC
				445A.123 to 445A.2234, inclusive.
3. Each standard is set to protect the
				beneficial use which is most sensitive with respect to that particular
				standard.
4. NAC 445A.1242 to
				445A.2234, inclusive, prescribe numerical standards for water quality and
				designate beneficial uses at particular control points.
