Eagle River, Alaska, PM-10 Maintenance Plan Summary


Eagle River PM10 Redesignation and Limited Maintenance Plan 2nd 10-Year Maintenance Plan Summary

Background of the Plan: On August 7, 1987, EPA designated the Community of Eagle River as a PM10 nonattainment area (NAA) due to measured violations of the 24-hour PM10 National Ambient Air Quality Standard (NAAQS). On November 6, 1991, the Eagle River NAA was subsequently classified as moderate under sections 107(d)(4)(B) and 188(a) of the CAA. The State submitted a PM10 attainment plan on October 15, 1991. EPA took final action to approve the plan on August 13, 1993 (58 FR 43084).

On September 29, 2010, the State requested that EPA redesignate the Eagle River NAA to attainment for PM10 and submitted the Eagle River PM10 Limited Maintenance Plan(LMP). On October 19, 2010, EPA made a determination that the Eagle River nonattainment area had attained the PM10 NAAQS by the applicable attainment date of December 31, 1994 (75 FR 64162). On January 7, 2013, EPA took direct final action to approve the LMP submitted by the State of Alaska for the Eagle River NAA and concurrently redesignate the area to attainment for the PM10 NAAQS (78 FR 900).

Summary of the Plan: The Eagle River PM10 LMP will continue to use the permanent and enforceable control measures used in the Eagle River moderate PM10 SIP that included road paving and surfacing projects that address fugitive dust. The program paved 22 miles of road which equals almost half of the roads in the area. The Municipality of Anchorage (MOA) commits itself to maintenance of the roads during their 10-15 year lifetime and resurfacing thereafter. The MOA also will work with the Alaska Department of Transportation and Public Facilities to limit the amount of silt allowed in winter traction sand as well as explore other road maintenance techniques that minimize road dust while still cleaning and maintaining safe roads.
