Section 18 AAC 75.495 - Regional master discharge prevention and contingency plan boundaries(a) Three coastal areas and one inland area, and associated geographic zones as described in (b) of this section, are established for the regional master oil and hazardous substance discharge prevention and contingency plan boundaries as required by AS 46.04.210. Planning areas and geographic zones are depicted on the map in Figure 1. The area boundaries are as follows: (1) the Southeast Alaska Area planning boundaries mirror the Southeast Alaska Captain of the Port Zone, and extend seaward from the coastline 200 nautical miles to the Exclusive Economic Zone; the Area also extends inland 1,000 yards; the Southeast Alaska geographic zone, as defined in (b) of this section, lies partially within the Southeast Alaska Area;(2) the Prince William Sound Area planning boundaries mirror the Prince William Sound Captain of the Port Zone and extend seaward from the coastline 200 nautical miles to the Exclusive Economic Zone; the Area also extends inland 1,000 yards and includes the Lowe River from Port Valdez to Thompson Pass; the Prince William Sound geographic zone, as defined in (b) of this section, lies partially within the Prince William Sound Area;(3) the Arctic and Western Alaska Area planning boundaries mirror the Western Alaska Captain of the Port Zone and extend seaward from the coastline 200 nautical miles to the Exclusive Economic Zone; the Area also extends inland 1,000 yards, and includes the Knik River up to Old Glenn Highway Bridge, the Kuskokwim River up to Bethel Old Army Airstrip, the Kvichak River up to Levelock Creek, the Naknek River up to King Salmon Quinault Landing, the Nushagak River up to Black Point, the Wood River up to South end of Sheep Island, and the Yukon River up to Pitka's Point and the Andreafsky River confluence, not including St. Mary's; the following geographic zones, as defined in (b) of this section, lie partially within the Arctic and Western Alaska Area: (G) Prince William Sound; and(4) the Alaska Inland Area includes all terrestrial land of the state 1,000 yards inland of the coastline not encompassed by the planning areas in (1) - (3) of this subsection; portions of all 10 geographic zones described in (b) of this section lie partially within the Alaska Inland Area.(b) The 10 geographic zones are defined by the department as follows: (1) Southeast Alaska Geographic Zone: that zone east of 142° W. longitude and south of a line just west of Icy Bay that connects the U.S.-Canadian border with the Gulf of Alaska, including adjacent shorelines and state waters, and having as its seaward boundary a line drawn so that each point on it is 200 nautical miles from the baseline from which the territorial sea is measured;(2) Prince William Sound Geographic Zone: that zone south of 63° 30' N. latitude, west of the zone described in (1) of this subsection, and east of the zone described in (3) of this subsection, including adjacent shorelines and state waters, and having as its seaward boundary a line drawn so that each point on it is 200 nautical miles from the baseline from which the territorial sea is measured;(3) Cook Inlet Geographic Zone: that zone encompassed by the boundaries of the Kenai Peninsula Borough, the Municipality of Anchorage, and the Matanuska-Susitna Borough, including adjacent shorelines and state waters, and having as its seaward boundary a line drawn so that each point on it is 200 nautical miles from the baseline from which the territorial sea is measured;(4) Kodiak Island Geographic Zone: that zone encompassed by the boundaries of the Kodiak Island Borough, extending from the Barren Islands at the north to Chirikof Island and the Semidi Island group at the south, and the coastal area watershed draining to the Shelikof Strait on the south side of the Alaska Peninsula from Cape Kilokak to Cape Douglas; the Kodiak archipelago and west side of Shelikof Strait within the Kodiak Island Borough is approximately 100 miles wide and 250 miles long; it includes more than 5,000 square miles of land, no point of which is more than 15 miles from the sea, including adjacent shorelines and state waters, and having as its seaward boundary a line drawn so that each point on it is 200 nautical miles from the baseline from which the territorial sea is measured;(5) Aleutian Island Geographic Zone; that zone encompassed by the boundaries of the Aleutians East Borough, the Aleutians West Census Area, and the Pribilof Islands, including adjacent shorelines and state waters, and having as its seaward boundary a line drawn so that each point on it is 200 nautical miles from the baseline from which the territorial sea is measured;(6) Bristol Bay Geographic Zone: that zone encompassed by the boundaries of the Dillingham Census Area, the Bristol Bay Borough, and the Lake and Peninsula Borough, including adjacent shorelines and state waters, and having as its seaward boundary a line drawn so that each point on it is 200 nautical miles from the baseline from which the territorial sea is measured;(7) Western Alaska Geographic Zone: that zone north of the zone described in (6) of this subsection, encompassed by the boundaries of the southernmost boundary of the Bering Straits Native Corporation, and Iditarod and Kuspuk Regional Educational Attendance Areas, including adjacent shorelines and state waters, and having as its seaward boundary a line drawn so that each point on it is 200 nautical miles from the baseline from which the territorial sea is measured;(8) Northwest Arctic Geographic Zone: that zone encompassed by the Northwest Arctic Borough and the Bering Straits Native Corporation, including adjacent shorelines and state waters, and having as its seaward boundary a line drawn so that each point on it is 200 nautical miles from the baseline from which the territorial sea is measured;(9) North Slope Geographic Zone: that zone encompassed by the boundaries of the North Slope Borough, including adjacent shorelines and state waters, and having as its seaward boundary a line drawn so that each point on it is 200 nautical miles from the baseline from which the territorial sea is measured; and(10) Interior Alaska Geographic Zone: that zone of the state not included in (1) - (9) of this subsection.(c) If the department finds that a discharge that could occur beyond the territorial sea would not have a significant adverse effect on the resources of the state or on other interests of the state, the department may adjust the seaward boundary of a geographic zone established in (b) of this section to exclude that area.(d) In this section, the "Captain of the Port Zone" boundaries are those established in 33 C.F.R. 3.85-10, as revised as of July 2, 2007, and adopted by reference, and 33 C.F.R. 3.85-15, as revised as of March 21, 2008, and adopted by reference.
