Lakeview Air Quality Maintenance Plan

Lakeview PM10 maintenance area

On June 19, 2006, EPA approved the Maintenance Plan and associated rules and EPA has changed the legal status of Lakeview from nonattainment to attainment for PM10 effective July 19, 2006.


In 1994, the Town of Lakeview became a nonattainment area for particulate matter (PM10). Previously, DEQ established a PM10 monitor and monitored high levels of PM10 in the airshed. The PM10 concentrations were high enough to cause a violation of the air quality standard also known as National Ambient Air Quality Standard (NAAQS). This violation meant two things. DEQ needed to write a plan to bring Lakeview back into compliance with the standard. The plan needed to be approved by Environmental Protection Agency (EPA). Additionally, added restrictions would be placed on Lakeview to limit new and expanding industries and significant transportation projects would need to be reviewed to determine their compliance with the plan. The plan and rules addressing Lakeview industry were prepared by DEQ in April 1995. The Environmental Quality Commission (EQC) adopted the plan and rules shortly thereafter.

The Town decided to hire an Air Quality Coordinator and establish an ongoing air quality committee to provide direction on improving the air quality in Lakeview. Several projects were conducted yearly in Lakeview to improve the air, including a voluntary woodstove advisory program, a public awareness program, restrictions on open burning and a school-aged children education program. Additionally, a woodstove replacement program was implemented to help low income individuals replace their uncertified woodstove.

The program was successful. Ambient air quality PM10 concentrations have been reduced over the years. On July 26, 2001, EPA acknowledged that Lakeview has attained the air quality standards since 1999. Since then, PM10 levels have remained well below federal standards.

On August 11, 2005, the EQC approved a revised State Implementation Plan including the proposed Lakeview PM10 maintenance plans and supporting appendices, and adopted the associated industrial rules.
