CAIRCAMR: Annual Reconciliation


1
CAIRCAMRAnnual Reconciliation

• EPA Region 7 Workshop
• Kansas City
• August 16 2007
• Mary Shellabarger

2
Where do Allowances Come From?

• CAIR NOx and CAMR
• Regionwide cap divided into State budgets
• Distributed within State based on SIP/SP or
  FIP/FP
• Plus optin allocations CAIR only
• Plus CSP CAIR NOx Annual only
• CAIR SO2
• Utilizes already existing Acid Rain allowances
• Plus optin allocations

3
State Budgets Initial Allocations

• Most sources receive a set amount of allowances
  for each control period ozone season/calendar
  year at least three years in advance
• determined by a methodology specific to each
  SIP/State Plan or FIP/Federal Plan
• total of initial allocations must be within State
  trading budget
• initial allocation period varies by SIP/SP FIP/FP

4
State Budgets SetAside Allocations

• Sources may receive allowances from State
  setaside accounts
• new units
• energy efficiency
• timing determined by effective rule
• usually once a year within control period

5
Compliance Supplement Pool

• Sources may receive CSP allowances in the NOx
  annual program only
• One time allocation of total of 200000
  allowances distributed among States
• Allocations will be made at end of 2009
• Determined by SIP/FIP
• Early reductions in 2007 or 2008
• Electric reliability concerns

6
OptIn Allocations under CAIR

• Not all States adopting optin provisions
• Optin is program specific
• Optin sources will receive allowances each year
• determined by optin methodology
• takes into account previous years operations

7
Allowances

• Specific to each program in CAIR/CAMR
• Identified by 12 digit serial number
• first four digits are the compliance use date
  aka vintage
• last eight digits are sequential
• cannot use allowance for compliance prior to its
  vintage year
• Reported in blocks
• example 201000123400 201000123499
• represents block of 100 allowances

8
Private Allowance Transfers

• Negotiate the trade of allowances
• Transferor seller notifies EPA of transfer
• Log on to CAMD Business System CBS and perform
  transfer instantaneously
• email confirmation to both parties
• Fill out and mail a paper form to EPA
• written confirmation to both parties via US mail

9
Annual Reconciliation

• Annual process of deducting allowances to account
  for the control period emissions
• Separate process for each program
• CAIR NOx annual
• CAIR NOx ozone
• CAMR
• CAIR SO2 combined with Acid Rain

10
Annual Reconciliation Eligible Allowances

• Allowances used for compliance
• only allowances of a vintage for the current
  year or an earlier year may be used
• Allowance transfer freeze
• the date after which allowances that may be used
  for compliance cannot be transferred into or out
  of a unit or overdraft account

11
Annual Reconciliation Deadlines

• Ozone Season program
• Nov 30 allowance transfer freeze
• final allowance transfers must be complete
• Annual programs
• March 1 allowance transfer freeze
• final allowance transfers must be complete

12
Process at EPA

• A few days before the allowance transfer freeze
  EPA compares preliminary emissions data with
  allowance account holdings
• EPA makes courtesy calls to alert DR of potential
  problem
• Emissions data received from sources and
  qualityassured
• Final allowance transfers received from sources
  and processed

13
Process cont.

• Emissions and allowances compared by Allowance
  Management System and deductions are processed
• Currently we do this on one day for everyone
• New reporting system will allow us to do this on
  a sourcebysource basis when emissions data are
  received
• Excess emissions penalties calculated if
  necessary

14
Deductions for CAIR NOx and CAMR

• Emissions determined at monitoring level
• Unit or stack
• Conventional rounding to whole number
• Emissions summed to source total
• Source emissions total compared to allowance
  holdings in source account
• Deductions made at 1 1 ratio
• One allowance per ton NOx or ounce Hg

15
CAIR NOx and CAMR Excess Emissions

• When there are not enough allowances to cover
  emissions in the source account
• Allowances are deducted from following years
  allocation at 31 rate
• 3 allowances for each ton NOx or ounce Hg of
  excess
• Other enforcement action possible

16
CAIR SO2Annual Reconciliation

• EPA Region 7 Workshop
• Kansas City
• August 16 2007
• Mary Shellabarger

17
Deductions for CAIR SO2

• Compliance is determined in 2 steps to meet the
  continuing requirements of title IV and new
  requirements of CAIR.
• Step 1 all Acid Rain deductions are made
• Step 2 any additional deductions to complete
  CAIR compliance are done

18

Deductions for CAIR SO2 cont.

• CAIR SO2 Allowance definition specifies
  different values based upon vintage years
• Retirement ratios do not apply to title IV
  sources outside the CAIR region.

Implementing a ratio of Pre2010 SO2 allowance
1.00 tons of SO2 emissions
2010 2014 SO2 allowance 0.50 tons of
