Layer Name: Water Quality Classifications Shapefile Name: ClassWater Layer Type: Polygon Status: Complete Geog. Extent: Main Hawaiian Islands Projection: Universal Trans Mercator, Zone 4 (Meters) Datum: NAD 83 Description: This dataset contains those marine Water Quality Standards Classifications surrounding the main Hawaiian Islands as specified in Hawaii Administrative Rules Title 11, Department of Health, Chapter 54 Water Quality Standards. Source : DOH Water Quality Classification Maps, DOH Water Quality Classification jpg's History: The original Water Quality Classifications dataset, Wqclass, was first transformed from UTM Zone 4, Old Hawaiian to UTM Zone 4, NAD 83 using the Hawaii Datums and Projections extension in ArcView 3.2. The transformed dataset was amended to incorporate the following changes: 1)Kahoolawe erased from water standards classification polygon, 2)Sand Island erased from water standards classification polygon, 3)corrected the water standards classification boundary between Kahoolawe and Maui, 4)corrected the water standards classification designations around Hawaii island, 5)corrected the water standards classification designation around Kahoolawe, and 6)deleted the polygons representing land masses (i.e. islands). Jpeg images were downloaded from the State Department of Health’s website and displayed in ArcView using the Jpeg Image Support extension. The images were positioned and manipulated to correspond with the Niihau coastline using the Image Georeferencing Tools and Image Analysis extensions. The Niihau coastline is part of the State’s coastline layer. The water standards classifications boundary around Niihau was digitized from the jpeg. The Niihau water standards classification boundary was then merged with the amended class water dataset. Completed December, 2002.

(from Hawaii Administrative Rules, Title 11, Chapter 54): It is the objective of class A waters that their use for recreational purposes and aesthetic enjoyment be protected. Any other use shall be permitted as long as it is compatible with the protection and propagation of fish, shellfish, and wildlife, and with recreation in and on these waters. These waters shall not act as receiving waters for any discharge which has not received the best degree of treatment or control compatible with the criteria established for this class. No new sewage discharges will be permitted within embayments. No new industrial discharges shall be permitted within embayments, with the exception of: (A) Acceptable non-contact thermal and drydock or marine railway discharges, in the following water bodies: (i) Honolulu Harbor, Oahu; (ii) Barbers Point Harbor, Oahu; (iii) Keehi Lagoon Marina Area, Oahu; (iv) Ala Wai Boat Harbor, Oahu; and (v) Kahului Harbor, Maui. (B) Storm water discharges associated with industrial activities (defined in 40 C.F.R. Section 122.26(b)(14)) which meet, at the minimum, the basic water quality criteria applicable to all waters as specified in section 11-54-04, and all applicable requirements specified in the chapter 11-55, titled "Water Pollution Control"; and (C) Discharges covered by a National Pollutant Discharge Elimination System general permit, approved by the U.S. Environmental Protection Agency and issued by the Department in accordance with 40 C.F.R. Section 122.28 and all applicable requirements specified in chapter 11-55, titled "Water Pollution Control". Class AA. (from Hawaii Administrative Rules, Title 11, Chapter 54): It is the objective of class AA waters that these waters remain in their natural pristine state as nearly as possible with an absolute minimum of pollution or alteration of water quality from any human-caused source or actions. To the extent practicable, the wilderness character of these areas shall be protected. No zones of mixing shall be permitted in this class: (A) Within a defined reef area, in waters of a depth less than 18 meters (ten fathoms); or (B) In waters up to a distance of 300 meters (one thousand feet) off shore if there is no defined reef area and if the depth is greater than 18 meters (ten fathoms). The uses to be protected in this class of waters are oceanographic research, the support and propagation of shellfish and other marine life, conservation of coral reefs and wilderness areas, compatible recreation, and aesthetic enjoyment. The classification of any water area as Class AA shall not preclude other uses of the waters compatible with these objectives and in conformance with the criteria applicable to them; Attribute Value Definitions: STANDARD STANDARD: 1 Restrictive 2 Open Coastal Waters 3 Oceanic Waters NOTE: Data not to be used for navigational purposes.
