2nd Implementation Period - Regional Haze State Implementation Plan

Public Notice Version

Amendments to: State Air Quality Control Plan Volume III: Analysis of Problems, Control Actions; Section III. K.13: Areawide Pollutant Control Program for Regional Haze

The Regional Haze Program was created to protect and improve visibility at specified parks and wilderness areas within Alaska and the rest of the United States by limiting or controlling human-generated pollution which generates noticeable and measurable visibility impairment.

States are required to generate “state implementation plan,” known as a SIP, to demonstrate how each state has made progress over the previous ten-year implementation period and how it will ensure improvement in the next implementation period. In this SIP, Alaska must show visibility improvement during the 20% Most Impaired Days (MID) and cannot have declining visibility quality during the 20% Clearest Days. This is intended to assist the state in meeting the goal of the federal program, which is to return each Class I Area to natural visibility conditions by the end of 2064.

Note: For convenience, the combined and individual sections are available for download in the links below. However, only the individual appendices can be downloaded due to the size of the combined document. Also, Appendix F is divided into three parts because of its size.
