Proposed “BART Trading” Rule Bill Grantham September 1, 2005
Overview: Purposes of Proposal • Fix RHR to enable use of alternatives to BART in light of CEED. • 308(e)(2)(i) • Enable western states/tribes to continue use of GCVTC/WRAP strategies • 309(a), (c) (g). • Establish minimum elements of: • -- Backstop SO2 provisions for west -309(d) • -- Cap and trade programs (WRAP and otherwise) -308(e)(2)(vi)
Source-by Source BART 1999 RHR: 308(e)(1) 2001 Guidelines proposed Incl. Trading section 2002 American Corn Growers 2004 Guidelines + 308(e)(1) revisions (re)proposed 2005 Guidelines Final 6/15 Trading section omitted due to CEED. Instead, separate rule→ Trading/alternatives 1999 RHR: 308(e)(2) & 309 2000 WRAP submits Annex 2003 Annex Rule 2005 CEED nixes Annex Rule 2005 (8/1) – Trading Rule proposed Historical Background
CEED v. EPAD.C. Circuit, Feb. 18, 2005 • Granted petition requesting that “Annex Rule” be vacated. • Basis of decision: BART methodology used in Annex was invalid under American Corn Growers • Specifically, the 4 non-visibility factors* were applied source-by-source, but visibility was only applied on a “group” basis. • Role EPA “coercion” in court’s reasoning not entirely clear. *4 factors are cost of compliance, remaining useful life of source, energy and nonair environmental impacts, and existing controls.
CEED v. EPAD.C. Circuit, Feb. 18, 2005 • Result: • Rule which governed the 6 §309 SIPs vacated; • New deadlines and regulatory mechanism needed if GCVTC/WRAP strategies are to proceed; • Provisions governing how alternative trading programs are shown to be “better than BART” must be revised to comply with CEED decision.
Fix to “Group BART” Flaw308(e)(2)(i) • Key: Change directive for estimating “what BART is” by replacing bifurcated approach with cross-reference to 308(e)(1) • i.e., state is simply directed to calculate emissions reductions/visibility benefits under source-by-source BART. • Potential for flexibility in methodology is discussed in preamble
308(e)(2)(i) As Proposed • (A) list all BART-eligible sources • (B) list source categories in alt. Program • (C) analysis of vis. Improvement at each affected C1 area from application of BART (per (e)(1)) to each source subject to BART in each affected category • (D) analysis of emiss. reduction & vis. improvement under alt. Program • (E) show that (D) makes greater progress than (C) per 308(e)(3).
308(e)(3): Finalized 6/15/05Cross referenced by 308(e)(2)(i)(E) [previous slide] • 308(e)(2) satisfied if: • Emission reductions are greater under alternative and geographic distribution of emissions not substantially different; • Or, if distribution is different: • Visibility does not decline at any Class I area; • Alternative program produces greater overall improvement based on average across all areas.
Other notes on “Better than BART” Provisions [308(e)(2)(i)] • Sources “subject to BART” in benchmark: state has same discretion as in source-by-source BART • May assume “all in” or make determination per guidelines – 0.5 dv, etc. • Presumptive EGU standards apply to same extent as in (e)(1) BART • Apply presumptions unless other control levels shown appropriate on unit-specific basis.
Other notes on “Better than BART” Provisions [308(e)(2)(i)] • Demonstration to be made at “affected” Class I areas (not necessarily all 156) • EPA seeks comment on whether methodology of 308(e)(3) should be sole means of demonstration, or whether other factors could be considered
Options under 308(e)(2)(i)(C):[1] Source-by-source • Do BART analysis based on source-by-source visibility modeling • Using CALPUFF • Using a regional model with source tracing –e.g., CAMx with PSAT • Most obviously legally defensible method • Resource prohibitive?
Options under 308(e)(2)(i)(C):[2] State discretion to do group BART • Court was clear that EPA may not require “group BART” even in context of an optional program: • “. . . EPA cannot under §309 require states to exceed invalid emissions reductions (or, to put it more exactly, limit them to a §309 alternative defined by an unlawful methodology.” (emph. added) • Not clear whether states barred from using group BART as long as EPA doesn’t require such. EPA believes states retain that discretion. • Therefore, could use “group” approach or some hybrid
Options under 308(e)(2)(i)(C):[3] Use most-stringent case BART • Where a requirement other than BART determines the level of emission reductions necessary . . . • CAIR • Reasonable progress as related but separate requirement than BART: where alt. program covers larger universe of sources • the concerns of CEED do not apply – BART benchmark is not forcing “invalid” reductions • Therefore, state may apply most-stringent BART assumptions in better than BART analysis.
RHR Revisions to allow continued use of GCVTC/WRAP Strategies • “Annex” provisions repealed due to vacature • 309(f) (calling for Annex submittal) • 309(h) (codifying WRAP Annex) • Consequence: milestones and all program details must be resubmitted • E.g, new source & tribal set asides, allocation methodology, etc. • Basic requirements for backstop SO2 program SIP requirements provided in 309(d)(4) • Lily Wong to discuss in detail
RHR Revisions to allow continued use of GCVTC/WRAP Strategies • Timing – 309 SIPs due at same time as 308: 12/17/07 [309(c)] • TIPs may be submitted later • “Annex” process not to be repeated – go directly to SIPs/TIPs • Default to 308 – moved to “purpose” provision [309(a)] • Because 308/309 due at same time, no longer a need to provide default trigger for failure to submit 309 by a date certain
RHR Revisions to allow continued use of GCVTC/WRAP Strategies • No degradation as minimum element of reasonable progress under 309 • Preamble: projection of visibility improvement [309(d)(2)] and periodic SIP revisions [309(d)(10)] must show no degradation on best and worst 20% days
RHR Revisions to allow continued use of GCVTC/WRAP Strategies • Additional Class I Areas [309(g)] • As before, may build on 309 strategy to cover other areas, based on a 308 reasonable progress analysis. • Eliminating requirement to declare 308/309 choice ahead of time (no longer relevant)
