Delaware’s Proposed Visibility State Implementation Plan (SIP) Revision

1. TITLE OF THE REGULATIONS:

Delaware’s Proposed Visibility State Implementation Plan (SIP) Revision.

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.

States are required to develop a series of SIPs to address visibility impairment in Class I areas and make reasonable progress toward achieving natural visibility conditions. This proposed SIP covers the 2nd implementation period of 2018 - 2028.

3. POSSIBLE TERMS OF THE AGENCY ACTION:

None.

4. STATUTORY BASIS OR LEGAL AUTHORITY TO ACT:
