CAA Section 111(d)/129 Delegation

Congress added Section 129 to the Clean Air Act (CAA) in 1990 specifically to address emissions from solid waste combustion. Sections 111 and 129 require EPA to establish new source performance standards (NSPS) for new units, while sections 111(d) and 129 require the Agency to establish Emission Guidelines for existing units. Both the NSPS and the Emission Guidelines under section 129 use a MACT type approach as used under section 112.

NSPS are direct Federal regulations that apply to new sources. Emission Guidelines do not directly regulate solid waste combustion units, but rather, establish requirements for States Plans which are the vehicle by which States implement the Guidelines. Once approved, these State Plans become Federally enforceable. If a State does not seek approval of a State Plan, the Federal Plan applies.
