Missouri State Implementation Plan Revision – 2008 Lead NAAQS Compliance Plan – Exide Technologies Canon Hollow Facility

As required by Section 110(a) of the Clean Air Act, Missouri’s State Implementation Plan (SIP) must ensure attainment and maintenance of all National Ambient Air Quality Standards (NAAQS). The Missouri Department of Natural Resources’ Air Pollution Control Program is proposing to amend and strengthen the Missouri SIP to address violations of the 2008 Lead (Pb) NAAQS of 0.15 micrograms per cubic meter (μg/m3), based on a rolling three-month average.  These violations are located in the vicinity of Forest City in Holt County, MO near the Exide Technologies Canon Hollow Secondary Lead Smelting Facility. This plan was developed in conjunction with the revised National Emission Standards for Secondary Lead Smelters [40 CFR 63 Subpart X] which took effect on January 6, 2014.  The SIP revision includes an attainment demonstration using air dispersion modeling and a consent judgment containing emission limitations and contingency measures.

Missouri State Implementation Plan Revision – Regional Haze Plan 5-Year Progress Report

The federal Clean Air Act establishes requirements for the protection of visibility in Class I areas, consisting of national parks and wilderness areas.  States are required to submit state implementation plans (SIPs) that demonstrate reasonable progress toward meeting the national goal of a return to natural visibility conditions in Class I areas by 2064.  There are two Class I areas in Missouri:  Hercules Glades Wilderness Area and Mingo National Wildlife Refuge.  Missouri’s regional haze SIP, which was submitted to the U.S. Environmental Protection Agency in August 2009, established visibility goals for the year 2018 for each of the state’s Class I areas in order to make reasonable progress toward the 2064 goal.  The purpose of this report is to assess progress made toward the 2018 visibility goals in Hercules Glades and Mingo in the five years since Missouri’s regional haze SIP was submitted to EPA.  This 5-year progress report demonstrates that both of Missouri’s Class I areas are expected to meet their 2018 visibility goals based on control strategies currently in place, which largely consist of sulfur dioxide and nitrogen oxides emission reduction measures for utilities, industrial boilers, and other sources.
