7 Del. Admin. Code § 1138-1.0
Title III of the Clean Air Act Amendments of November 15, 1990 revised Section 112 of the 1970 Clean Air Act that addressed hazardous air pollutants (HAPs) and changed the way that these pollutants were to be regulated. Title III identified the specific HAPs and established the regulatory approach that the U.S. Environmental Protection Agency (EPA) would take to control their emissions from stationary sources.
The EPA is initially required to promulgate emission standards that are based on the maximum achievable control technology (MACT) for categories or subcategories of sources according to a Congress-mandated schedule. Within eight years of promulgating these MACT-based standards, the EPA is required to address the remaining or residual risk by promulgating, if needed, standards necessary to provide an ample margin of safety to protect public health or to prevent an adverse environmental effect. The initial MACT-based regulations are at 40 CFR Part 63.
The Department is adopting these regulations in response to 7 Del.C., Ch 60.
