Arizona Administrative Code › Title 18 - ENVIRONMENTAL QUALITY › Chapter 11 - DEPARTMENT OF ENVIRONMENTAL QUALITY - WATER QUALITY STANDARDS › Article 2 - WATER QUALITY STANDARDS FOR NON-WOTUS PROTECTED SURFACE WATERS › Section R18-11-216 - The Protected Surface Waters List › Table B - WOTUS Protected Surface Waters

Current through Register Vol. 30, No. 28, July 12, 2024
The waters listed in this table have been tentatively
					 identified by ADEQ as WOTUS, under the law governing on 8/26/2022.
					 Notwithstanding its inclusion on the list below, the status of a particular
					 water in this table can be contested by a person in an enforcement or permit
					 proceeding, a challenge to an identification as an impaired water, or a
					 challenge to a proposed TMDL for an impaired water. Any changes to Table B will
					 be made through formal rulemaking.
The waters on this list have their designated uses assigned
					 by Title 18, Chapter 11, Article 1. Coordinates are from the North American
					 Datum of 1983 (NAD83). All latitudes in Arizona are north and all longitudes
					 are west, but the negative signs are not included in the WOTUS Protected
					 Surface Waters Table. Some web-based mapping systems require a negative sign
					 before the longitude values to indicate it is a west longitude.
