Compliance Options 3. Can Not Comply with the Emission Standards Area Source Major Source Fuel Management Fuel Switching Controls Controls Fuel Management Fuel Switching Synthetic Minor Energy Efficiency i Improvements 19
Output-based Emission Standards Output-based Emission Standards Incentivizes implementation of energy efficient technologies to minimize the generation of emissions 20
Output-Based Emission Standards Fuel Input Energy (lb pollutant per MMBtu heat input) Steam Output Energy (lb pollutant per MMBtu steam output) 21
Capital Investment Add-on Control Device(s) Energy Efficiency Project(s) 22
Output-Based Emission Standards How were they determined? Boiler Efficiency Heat-Input Based Limits Subcategory Hg Emission Limit (lb Hg per MMBtu of heat input) Hg Emission Limit (lb Hg per MMBtu of steam output) Boiler Efficiency (%) Existing Boiler Designed to Burn Solid Fuel 3.10E-06 3.50E-06 88.6 23
Output-Based Emission Standards How are they used? Determine Current Boiler Output-Based Emissions Establish Output t Energy Benchmark Investigate Energy Efficiency Projects Quantify Emission Reductions Apply Percent Reduction to Current Boiler Output-Based Emissions 24
Energy Output Reduction Example Benchmark Year* = 2,175,000 MMBtu/yr Year After* = 1,957,500 500 MMBtu/yr Tested Hg Tested Hg Adjusted Hg Emissions (lb Hg per MMBtu of heat input) Emissions (lb Hg per MMBtu of steam output) Emissions (lb Hg per MMBtu of steam output) 3.40E-06 (Limit 3.10E-06) 3.84E-06 (Limit 3.50E-06) 3.45E-06 *Production is assumed to be the same for both years. 25
Energy Output Reduction Example Subcategory Hg Emission Limit (lb Hg per MMBtu of steam output) Hg Adjusted Emissions (lb Hg per MMBtu of steam output) Result Existing Boiler Designed to 3.50E-06 06 3.45E-06 PASS Burn Solid Fuel 26

What is Left? Ground Rules Regulatory Framework Regulated Pollutants Emission Limitations Compliance Options Work Practice Standards Startup, Shutdown, and Malfunction Things to Take Away 28
Work Practice Standards Area Source Major Source Tune-up Tune-up Energy Energy Assessment Assessment Startup Good Combustion Shutdown Practices Startup Shutdown 29
ASBM ASBM Tune-ups Final Rule (March 21, 2011) ASBM Amendments (December 23, 2011) Every 2 years Every 2 years March 21, 2012 No Action Assurance Letter Every 5 years (Seasonal Boilers) March 21, 2013 Fuel Type Requirements Common Fuel Meter 30
Tune-up Applicability Area Source Major Source New or Existing Coal-fired Boiler <10 MMBtu/hr New or Existing Biomass-fired Boiler New or Existing Oil-fired Boiler Limited-use it Boilers Natural gas, Refinery Gas or Gas 1 (Other) Boilers < 5 MMBtu/hr Gas 2 (Other), Light Liquid Boilers 31
Tune-up Requirements Area Source Burner Inspection Flame Pattern, p y Inspection Air-to-fuel system Inspection CO Optimization Recordkeeping No Report Submittal (1) As applicable, inspect the burner, and clean or replace any components of the burner as necessary (you may delay the burner inspection until the next scheduled unit shutdown, but you must inspect each burner at least once every 36 months). Major Source Burner Inspection Flame Pattern Inspection Air-to-fuel system Inspection CO Optimization Recordkeeping Report Submittal (1) Inspect the burner and clean or replace any components of the burner as necessary. 32
Energy Assessment Why? When and how often? Who is qualified? What equipment or systems need to be included? What does cost-effective mean? What needs to be done? 33
Energy Assessment ASBM Existing Final Rule (March 21, 2011) 10 MMBtu/hr Boiler System Energy Use System Qualified Personnel Maximum Duration March 21, 2014 ASBM Amendments (December 23, 2011) Existing 10 MMBtu/hr Boiler System Energy Use System Onsite O i Only Qualified Personnel Maximum Duration March 21, 2014 34
Energy Assessment Major Source Scope Maximum Time Compliance Date Date to Change Emission Reduction Credits 35
Good Combustion Practices O 2 Trim Systems Monitor Optimize Report Operator Training Startup Procedures Shutdown Procedures 36
Startup/Shutdown Periods Boiler MACT standards apply at all times. No exemptions from Boiler MACT standards during periods of Startup and Shutdown. U.S. EPA requires work practice standards for periods of Startupt and Shutdown in lieu of numerical emission limits. 37
Startup/Shutdown Area Source Major Source Minimize i i the boiler s startup and shutdown periods following the manufacturer s recommended procedures. Good Combustion Practices 38
Misc. Startup/Shutdown Area Source Major Source Startup/Shutdown t td Definitions Startup/Shutdown t td Definitions No SSM Plans No SSM Plans 39
Malfunction Malfunction means any sudden, infrequent, and not reasonably ypreventable failure of air pollution control and monitoring equipment, process equipment, or a process to operate in a normal or usual manner which causes, or has the potential to cause, the emission limitations in an applicable standard to be exceeded. Failures that are caused in part tby poor maintenance or careless operation are not malfunctions. 40
Periods of Malfunction Boiler MACT standards apply at all times. No exemptions from Boiler MACT standards during periods of Malfunction. U.S. EPA determines if a facility demonstrated a good faith effort to minimizing i i i emissions i and correcting a Malfunction. 41
Malfunction Process Notification of a Malfunction submitted to U.S. EPA within two (2) business days. Follow-up report submitted to U.S. EPA within 45 business days. U.S. EPA evaluates the reported information concerning the Malfunction to determine if further inquiry or enforcement action is required. Facility can only use Affirmative Defense in response to civil penalties if notification and report is submitted. 42
Affirmative Defense To use Affirmative Defense facilities must show a preponderance of evidence that: The excess emission was caused by a malfunction and was not preventable or reoccurring, and The facility expedited repairs, actions were documented in signed logs, and a root-cause analysis was completed. 43
SSM Plan No SSM Plan required; however may be more important now than ever due to potential enforcement action. 44
Things to Take Away The current status of the Boiler MACT rules? Where do I stand now? What are my compliance options? What are my compliance plans? Be in action! 45
