3 Air Emission Basics Criteria Pollutants Products of combustion: Nitrogen Oxides (NOx), Carbon Monoxide (CO), Sulfur Dioxide (SO2), Particulate Matter (PM) and Volatile Organic Compounds (VOC) or Non-methane hydrocarbons (NMHC)The Clean Air Act (CAA) requires EPA to identify sources of Hazardous Air Pollutants (HAPs) and develop regulations to limit these emissions.Boilers, Incinerators and Reciprocating Internal Combustion EnginesHazardous Air PollutantsList of 188 HAPs from the CAA can be found at
4 Air Emission Basics (continued) EPA has developed both Major and Area Source National Emission Standards for Hazardous Air Pollutants (NESHAPs) promulgated under 40 CFR 63Major vs. Area SourcesMajor sources have the Potential to Emit (PTE) greater than tpy individual HAP and 25 tpy combined HAPsArea sources are facilities that are not major sources - who do not have PTE above these levels either due to permit limitations or design capacity.Majority of Sources in NH are Area Sources
5 Hospital SpecificsHospitals in NH are area sources of HAPs based on the boilers and emergency generators currently permitted.To determine your facility’s classification, you must calculate your PTE of HAPs from all devices at your facility (boilers, emergency generators, ethylene oxide sterilizers, etc.)Hospitals typically burn traditional fuels in their boilers (coal, biomass, oil or gas) as opposed to solid waste.Presentation today is not covering HIMWI (none in NH – few, if any, in New England).Almost 97% of the hospitals in NH burn fuel oil alone or in combination with natural gas.One facility in NH operates 2 small (<10 MMBtu/hr) biomass boilers.Over 70% have at least one boiler >10 MMBtu/hr.
7 Overview of recent EPA actions affecting boilers EPA issued three rules that reduce emissions of HAPs:NESHAP for Industrial, Commercial, and Institutional Boilers and Process Heaters (40 CFR 63, Subpart DDDDD) (“Boiler MACT”)NESHAP for Area Sources: Industrial, Commercial, and Institutional Boilers (40 CFR 63, Subpart JJJJJJ) (“Boiler Area Source Rule”)Section 129 NSPS and Emission Guidelines for Commercial and Industrial Solid Waste Incinerators (CISWI)EPA also issued a final rule that defines “solid waste”Necessary to determine whether a source must meet boiler standards or an incinerator standardExplain delegation issue and the lead agency on each rule.
8 Overview of recent EPA actions affecting boilers (cont.) ScheduleProposals signed on April 29, 2010Published in the Federal Register on June 4, 2010Promulgations signed on February 21, 2011 (Court-ordered)Published in the Federal Register on March 21, 2011Effective Date: May 20, 2011EPA has initiated reconsideration of certain aspects of the boiler and CISWI rulesSome of the comments raise difficult technical issues that would benefit from additional public involvement.Stakeholders have petitioned for reconsideration of other issues.StayOn May 18, 2011, EPA delayed the effective date of the Boiler MACT and CISWIBoiler Area Source Rule and Solid Waste Definition are in effect even during the reconsideration process.Facilities need to comply with rules as they were promulgated.Key points:June 4, 2010 is the date that distinguishes “existing” devices from “new” devices.March 21, 2011 is the date that establishes future due dates for notifications, work practice standards.May 20, 2011 was the effective date of the Area Source Boiler Rule.Boiler MACT and CISWI are stayed and Boiler MACT, Area Source Boiler Rules and CISWI are under reconsideration.EPA’s Tentative Schedule for Reconsideration: Proposal due out October, 2011; Final April, 2012
9 Focus of Today’s Presentation: Boiler Area Source Rule Area Sources burning Traditional Fuel (oil)
10 Boiler Area Source Rule Rule is broken down based on:Boiler size:Small (<10 MMBtu/hr)Large (≥10 MMBtu/hr)Fuel type:Coal-fired unitsBiomass-fired unitsOil-fired unitsBoiler Construction:Existing prior to June 4, 2010New or reconstructed after June 4, 2010Note:NH has not taken delegation of the Boiler Area Source Rule. Therefore, the information presented here is based on the regulation and conversations that have taken place with EPA, Headquarters and Region 1, and are in some cases based on interpretations by EPA and DES as we have tried to work through various issues not clearly defined in the existing rule. In addition, any requirements in the existing rule may be changed in the future as a result of the reconsideration process. It is up to the source to review the regulation as it pertains to their specific situation, comply with the regulation as promulgated and keep informed of any changes.
11 Are any boilers not subject to this subpart? Any boiler covered by another part of 40 CFR 63Any boiler covered by CISWIHazardous waste boilersA boiler that is used specifically for research and development.This exemption does not include boilers that solely or primarily provide steam (or heat) to a process or for heating at a research and development facility.Any boiler that is used as a control device to comply with another Subpart of 40 CFR 63, provided that at least 50 percent of the heat input to the boiler is provided by the gas stream that is regulated under another subpart.Key points:Gas-fired boilers (as defined) are not subject to the Area Source Boiler Rule.Dual fired boilers (e.g. NG/#2 FO) that don’t meet or are unwilling to meet the gas-fired boiler definition would be subject to the rule when burning liquid fuel. (Existing: work practice standards; New: emission limitations and work practice standards)If a gas-fired boiler switches to dual fuel or liquid fuel only in the future, this constitutes fuel switching and the device would be considered “new”. At that point, the device would have to meet the oil-fired emission limit as well as tune-up.
12 Are any boilers not subject to this subpart? (continued) A hot water heater as defined in this subpart.Hot water heater means a closed vessel with a capacity of no more than 120 U.S. gallons in which water is heated by combustion of gaseous or liquid fuel and is withdrawn for use external to the vessel at pressures not exceeding 160 psig, … and … water temperatures exceeding 210°F.A gas-fired boiler as defined in this subpart.Gas-fired boiler includes any boiler that burns gaseous fuels not combined with any solid fuels, burns liquid fuel only during periods of gas curtailment, gas supply emergencies, or periodic testing on liquid fuel. Periodic testing of liquid fuel shall not exceed a combined total of 48 hours during any calendar year.Key points:Gas-fired boilers (as defined) are not subject to the Area Source Boiler Rule.Dual fired boilers (e.g. NG/#2 FO) that don’t meet or are unwilling to meet the gas-fired boiler definition would be subject to the rule when burning liquid fuel. (Existing: work practice standards; New: emission limitations and work practice standards)If a gas-fired boiler switches to dual fuel or liquid fuel only in the future, this constitutes fuel switching and the device would be considered “new”. At that point, the device would have to meet the oil-fired emission limit as well as tune-up.
13 Fuel Switching Rule Provisions A boiler is a new affected source if you commenced fuel switching from natural gas to solid fossil fuel, biomass, or liquid fuel after June 4, 2010.If you intend to switch fuels, and this fuel switch may result in the applicability of a different subcategory or a switch out of Subpart JJJJJJ due to a switch to 100 percent natural gas, you must provide 30 days prior notice of the date upon which you will switch fuels.If you own or operate an industrial, commercial, or institutional boiler and would be subject to this subpart except for the exemption for units covered by the CISWI rules, and you cease combusting solid waste, you must be in compliance with this subpart on the effective date of the waste to fuel switch.If you intend to commence or recommence combustion of solid waste, you must provide 30 days prior notice of the date upon which you will commence or recommence combustion of solid waste.
15 Emission Limits for Area Source Boilers Oil and Biomass Only SubcategoryEmission LimitsPM (lb/MMBtu)10 – 30 MMBtu/hr>30 MMBtu/hrNew Biomass0.070.03New OilExisting Biomass-Existing OilNote:The emission limit of 0.03 lb/MMBtu limit for PM from new devices is the same emission limit in the NSPS for new >30 MMBtu/hr boilers.
16 Energy Assessment [40 CFR 63, Subpart JJJJJJ - Table 2] One-time energy assessment performed by a qualified energy assessor.An energy assessment completed on or after January 1, 2008, that meets or is amended to meet the energy assessment requirements satisfies the energy assessment requirements.The energy assessment must include:A visual inspection of the boiler system,An evaluation of operating characteristics of the facility, specifications of energy using systems, operating and maintenance procedures, and unusual operating constraints,Inventory of major systems consuming energy from affected boiler(s),A review of available architectural and engineering plans, facility operation and maintenance procedures and logs, and fuel usage,A list of major energy conservation measures,A list of the energy savings potential of the energy conservation measures identified,A comprehensive report detailing the ways to improve efficiency, the cost of specific improvements, benefits, and the time frame for recouping those investments.EPA is hoping to come out with more detailed guidance on the energy assessment portion of the rule soon.NH DES is also going to be conducting Workshops on the rules and expanding the website with information and links to documents to aid facilities in complying with the rules, including but not limited to lists of qualified energy assessors, notification forms, Fact Sheets and Frequently Asked Questions.
17 Tune-up Requirement [63.11223(b)] 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).Inspect the flame pattern, as applicable, and adjust the burner as necessary to optimize the flame pattern. The adjustment should be consistent with the manufacturer’s specifications, if available.Inspect the system controlling the air-to-fuel ratio, as applicable, and ensure that it is correctly calibrated and functioning properly.Optimize total emissions of carbon monoxide. This optimization should be consistent with the manufacturer’s specifications, if available.
18 Tune-up Requirement [63.11223(b)] (continued) Measure the concentrations in the effluent stream of carbon monoxide in parts per million, by volume, and oxygen in volume percent, before and after the adjustments are made (measurements may be either on a dry or wet basis, as long as it is the same basis before and after the adjustments are made).Maintain onsite and submit, if requested, biennial report containing the following information:The concentration of CO in the effluent stream in ppm, by volume, and oxygen in volume percent, measured before and after the tune-up of the boiler.A description of any corrective actions taken as a part of the tune-up of the boiler.The type and amount of fuel used over the 12 months prior to the biennial tune-up of the boiler.If the unit is not operating on the required date for a tune-up, the tune-up must be conducted within one week of startup.
