Florida Department of Environmental Protection Summary of Proposed Amendments

Purpose and Scope Propose to be repealed Explanatory and extraneous 7October 20, 2010

Definitions Remove all definitions, propose to move to revised Insert a pointer to October 20, 2010

Ambient Air Quality Assessment Re-titled from “Ambient Air Quality Protection” to “Ambient Air Quality Assessment” Remove (1) and (2) regarding issuing of permits that will not interfere with “attainment or maintenance of any ambient air quality standard…”; Moved to proposed new section of (8) Ambient Air Quality Protection Rulemaking for General Permits, Exemptions, and Clarifying Amendments Renumber (3) and (4) regarding ambient air quality monitors but leave language mostly as is 9October 20, 2010

Ambient Air Quality Standards Section proposed to be repealed Standards set forth identical to, or less stringent than, current NAAQS in 40 C.F.R. Part 50, adopted by reference at Definition of “ambient air quality standard” in includes NAAQS therefore unnecessary to repeat the federal standards here Future revisions to NAAQS will also be adopted by reference at October 20, 2010

Prevention of Significant Deterioration Maximum Allowable Increases (PSD Increments) Section proposed to be repealed PSD increments in this section identical to 40 C.F.R (c) and adopted by reference in Definition of “maximum allowable increase” or “PSD increment” that references this federal rule added to in concurrent rulemaking Future revisions to PSD increments will be adopted by reference via this definition in October 20, 2010

Procedures for Designation and Redesignation of Areas Section proposed to be repealed Restates federal procedures the department is required to follow regardless of their presence in a DEP rule Further rendered unnecessary from other rule changes in this chapter (removing “PSD Area” in ) 12October 20, 2010

Designation of Air Quality Maintenance Areas Re-titled: Designation of Air Quality Attainment, Nonattainment, and Maintenance Areas, and proposed to be reduced to subsection (4), Designation of Air Quality Maintenance, only REMOVE: Language for designation of (1) attainment, (2) nonattainment, and (3) unclassifiable areas set forth in 40 C.F.R , adopted by reference Definition of “nonattainment” in revised to reference federal language More efficient implementation of impending EPA designations KEEP: Term “air quality maintenance area” used in DEP air rules to identify where pollutant-specific RACT rules apply, therefore preserved for state purposes 13October 20, 2010

Designation of Areas for Prevention of Significant Deterioration (PSD) Purposes Re-titled: Designation of Areas for Prevention of Significant Deterioration (PSD) Purposes Areas Reorganized to eliminate the use of the term “PSD area” Designations in 40 C.F.R. Part 81, adopted by reference Proposed revised definition of “baseline area” in refers to the federal designations, therefore this section can be reduced Minor source baseline dates preserved 14October 20, 2010

cont. PM 2.5 Added PM 2.5 baseline area proposed to be the entire state, consistent with other pollutants Sentence serving as a placeholder for when minor source baseline date is determined, pursuant to the revised definition of “minor source baseline date” in “Major source baseline date” for PM 2.5 defined in as date of publication of the PM 2.5 increments in F.R. Class I Areas Proposed to remove the listing of Class I areas and refer to their listing in 40 C.F.R. Part 81, Subpart D (Class I areas where visibility is determined to be an important value), adopted by reference AND list Bradwell Bay National Wilderness Area, since it is one of two Class I areas where visibility was not determined to be an important value 15October 20, 2010
