Delaware Proposed Visibility State Implementation Plan

1. TITLE OF THE REGULATIONS:

Delaware's Proposed Visibility State Implementation Plan

2. BRIEF SYNOPSIS OF THE SUBJECT, SUBSTANCE AND ISSUES:

The federal Clean Air Act mandates protection of visibility in Class I federal areas, such as national parks, forests and wilderness areas. Under the 1999 Regional Haze Rule, states are required to develop a series of State Implementation Plans (SIPs) to reduce visibility impairment with the express intent that; by 2064 the visibility in the Class I areas will be returned to natural conditions. This proposed SIP is the first SIP in this process, and it establishes that Brigantine National Wildlife Refuge (BNWR), NJ is the only Class I area that Delaware significantly impacts. Delaware coordinated with Class I states and the Mid-Atlantic/Northeast Visibility Union (MANE-VU) in the development of this proposed SIP to present strategies to lessen visibility impairment in BNWR.

This proposed SIP also shows that visibility impairment is primarily caused by sulfur dioxide, and to a lesser degree, primary particles and other particle precursors. These particles and particle precursors are transported from broad geographic areas, and are emitted from many source types. This proposed SIPs goal’s and emission reduction strategies demonstrate that adopted and enforceable State and Federal regulations and control measures meet long term strategies and “reasonable progress goals” by 2018, as established by Class I states and regional consultation process.
