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. 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.

The proposed SIP may be inspected online starting Dec. 1, 2021 in the Delaware Register of Regulations or in person, by appointment only, by contacting Renae Held at 302-739-9402 or by email at

The Department will accept public comment through the close of business on Jan. 13, 2022. Comments will be accepted in written form via email to, using the online form at, or by U.S. mail to the address below.
