ACTION:

Proposed rule.

SUMMARY:

EPA is proposing new source standards of performance for stationary spark ignition internal combustion engines. EPA is also proposing national emission standards for hazardous air pollutants for stationary reciprocating internal combustion engines that either are located at area sources of hazardous air pollutant emissions or that have a site rating of less than or equal to 500 brake horsepower and are located at major sources of hazardous air pollutant emissions.

II. Background

This action proposes new source performance standards (NSPS) that would apply to new stationary spark ignition (SI) internal combustion engines (ICE). New source performance standards implement section 111(b) of the Clean Air Act (CAA), and are issued for categories of sources which cause, or contribute significantly to, air pollution which may reasonably be anticipated to endanger public health or welfare. The standards apply to new stationary sources of emissions, i.e., sources whose construction, reconstruction, or modification begins after a standard for those sources is proposed. The NSPS for stationary SI ICE would be promulgated under 40 CFR part 60, subpart JJJJ.

This action also proposes national emission standards for hazardous air pollutants (NESHAP) from existing, new, and reconstructed stationary reciprocating internal combustion engines (RICE) with a site rating of less than or equal to 500 horsepower (HP) located at major sources, and existing, new, and reconstructed stationary RICE located at area sources. We are proposing these requirements to meet our statutory obligation to address hazardous air pollutants (HAP) emissions from these sources under sections 112(d) and 112(k) of the CAA. The final NESHAP for stationary RICE would be promulgated under 40 CFR part 63, subpart ZZZZ, which already contains standards applicable to stationary RICE with a site rating above 500 HP located at major sources.

We are proposing these two sets of regulations under one notice of proposed rulemaking because the source categories being addressed are practically identical. In other words, stationary engines located at major and area sources of HAP will also be affected by NSPS regulations. Based on the similarities, we decided that it would be appropriate to propose the regulations at the same time and attempt to bring some consistency between them.

III. Summary of this Proposed Rule

A. What is the source category regulated by this proposed rule?

The proposed NSPS apply to new stationary SI ICE. A stationary internal combustion engine means any internal combustion engine, except combustion turbines, that converts heat energy into mechanical work and is not mobile. Stationary ICE differ from mobile ICE in that a stationary internal combustion engine is not a nonroad engine as defined at 40 CFR 1068.30, and is not used to propel a motor vehicle or a vehicle used solely for competition. Stationary ICE include reciprocating ICE, rotary ICE, and other ICE, except combustion turbines. The proposed NESHAP applies only to stationary RICE. To our knowledge, no rotary or other types of stationary ICE exist at this time.

The SI NSPS address emissions from new, modified and reconstructed stationary SI engines. An SI engine is either a gasoline-fueled engine; or any other type of engine, with a spark plug (or other sparking device) and with operating characteristics significantly similar to the theoretical Otto combustion cycle. Spark ignition engines usually use a throttle to regulate intake air flow to control power during normal operation. Dual-fuel engines in which a liquid fuel (typically diesel fuel) is used for compression ignition and gaseous fuel (typically natural gas) is used as the primary fuel at an annual average ratio of less than 2 parts diesel fuel to 100 parts total fuel on an energy equivalent basis are considered SI engines for purposes of this proposed rule.

The NESHAP address emissions from existing, new, and reconstructed stationary engines less than or equal to 500 HP located at major sources and all stationary engines located at area sources. A major source of HAP emissions is a plant site that emits or has the potential to emit any single HAP at a rate of 10 tons (9.07 megagrams) or more per year or any combination of HAP at a rate of 25 tons (22.68 megagrams) or more per year, except that for oil and gas production facilities, a major source of HAP emissions is determined for each surface site. An area source of HAP emissions is a source that is not a major source.

If you are an owner or operator of an area source subject to this proposed rule, you are exempt from the obligation to obtain a permit under 40 CFR parts 70 or 71, provided you are not required to obtain a permit under 40 CFR 70.3(a) or 40 CFR 71.3(a) for a reason other than your status as an area source under this proposed rule.

1. SI NSPS

New source performance standards for stationary SI engines are issued under section 111(b) of the CAA. All new, modified and reconstructed stationary SI engines are covered regardless of size. The NSPS apply to stationary SI engines combusting any fuel (natural gas, gasoline, liquefied petroleum gas (LPG), compressed natural gas, landfill gas, digester gas, and any other applicable fuel). New source performance standards require these sources to control emissions to the level achievable by best demonstrated technology (BDT), considering costs and any non-air quality health and environmental impacts and energy requirements.

Under section 111 of the CAA, 42 U.S.C. 7411, the Administrator is required to publish, and periodically update, a list of source categories that in his or her judgment cause, or contribute significantly to, air pollution which may reasonably be anticipated to endanger public health or welfare. This list appears in 40 CFR 60.16. The list reflects the Administrator's determination that emissions from the listed source categories contribute significantly to air pollution that may reasonably be anticipated to endanger public health or welfare, and it is intended to identify major source categories for which standards of performance are to be promulgated.

EPA has determined that for purposes of NSPS regulations, the stationary internal combustion engine source category should be split into two source categories—SI engines and compression ignition (CI) engines. Proposed NSPS for stationary CI engines were published on July 11, 2005 (70 FR 39870).

2. NESHAP

The NESHAP portion of this action is a revision to the regulations in 40 CFR part 63, subpart ZZZZ, currently applicable to stationary RICE greater than 500 HP located at major sources, which were promulgated in 2004. Subpart ZZZZ of 40 CFR part 63 does not currently cover stationary engines located at area sources of HAP emissions, nor does it apply to stationary engines located at major sources with a site rating of 500 HP or less. When the subpart ZZZZ of 40 CFR part 63 regulations were promulgated in 2004 (69 FR 33474), EPA deferred promulgating regulations with respect to stationary engines 500 HP or less at major sources until further information on the engines could be obtained and analyzed. It was decided to regulate these smaller engines at the same time as we regulate engines located at area sources.

This action proposes to revise 40 CFR part 63, subpart ZZZZ, in order to address HAP emissions from stationary RICE less than or equal to 500 HP located at major sources and stationary RICE located at area sources. For stationary engines less than or equal to 500 HP at major sources, EPA must determine what is the appropriate maximum achievable control technology (MACT) for those engines under section 112(d)(3) of the CAA.

For stationary engines located at area sources, we have the flexibility to promulgate standards based on generally available control technology (GACT) under CAA section 112(d)(5). We are required to address HAP emissions from stationary RICE located at area sources under section 112(k) of the CAA, based on criteria set forth by EPA in the Urban Air Toxics Strategy described in the paragraph below.

On July 19, 1999, EPA announced in the
Federal Register
its plan for addressing exposure to air toxics in urban areas. The Urban Air Toxics Strategy (64 FR 38706) listed several source categories that emit one or more of the air toxic pollutants of greatest concern in urban areas. The stationary engine source category was one of the source categories listed and, as such, EPA is required to consider it for regulation. The strategy addressed sections 112(c)(3) and 112(k)(3)(B)(ii) of the CAA that instruct us to identify not less than 30 HAP which, as the result of emissions from area sources, present the greatest threat to public health in the largest number of urban areas, and to list sufficient area source categories or subcategories to ensure that emissions representing 90 percent of the 30 listed HAP are subject to regulation. The strategy included a list of 33 HAP judged to pose the greatest potential threat to public health in the largest number of urban areas (the urban HAP) and a list of area source categories emitting the listed HAP (area source HAP). Once listed, these area source categories shall be subject to standards under section 112(d) of the CAA.

We have divided the source category into the following subcategories: Stationary RICE less than 50 HP, landfill and digester gas stationary RICE, CI stationary RICE greater than or equal to 50 HP, and SI stationary RICE greater than or equal to 50 HP. The CI stationary RICE greater than or equal to 50 HP subcategory was further subcategorized into emergency and non-emergency engines, as was the

subcategory of SI stationary RICE greater than or equal to 50 HP. Spark ignition non-emergency stationary RICE greater than or equal to 50 HP were then subcategorized into 2 stroke lean burn (2SLB), 4 stroke lean burn (4SLB), and 4 stroke rich burn (4SRB) stationary RICE.

The regulatory approach being proposed in this action differentiates between gasoline, LPG, natural gas, and digester and landfill gas. Gasoline and LPG are fuels more commonly used in nonroad engines than stationary engines. Nonroad SI engines less than or equal to 19 kilowatt (KW) (25 HP) typically use gasoline. It is estimated that about 68 percent of SI nonroad engines above 19 KW (25 HP) use LPG. A smaller percentage of nonroad SI engines above 19 KW (25 HP) use gasoline (about 23 percent) and even less use compressed natural gas (about 9 percent). Natural gas fuel is more common in larger, stationary applications. Natural gas engines refer to all gaseous-fueled engines except those fueled by landfill and digester gas. Natural gas is primarily composed of methane and typically contains very low levels of sulfur. Other fuels used with stationary SI engines are landfill and digester gases. These gases are by-products of wastewater treatment and land application of municipal reuse. Landfill and digester gases, which are formed through anaerobic decomposition of organic materials, are principally comprised of methane and carbon dioxide, but small quantities of other compounds such as hydrogen sulfide, ammonia, volatile organic compounds, and particulate matter (PM) may also be present. These gases have a lower methane content than natural gas and may range from 50 to 65 percent. Although similar in composition to natural gas, there are some differences in the emissions from combustion of landfill and digester gases due to e.g., chlorinated compounds typically not found in natural gas. Both landfill and digester gases contain a family of silicon-based gases collectively called siloxanes. Combustion of siloxanes forms compounds that have been known to foul fuel systems, combustion chambers, and post-combustion catalysts.

B. What are the pollutants regulated by this proposed rule?

New source performance standards are developed under the authority of section 111 of the CAA. Emissions of criteria pollutants (those pollutants identified under section 110 of the CAA) are generally regulated under section 111 of the CAA, while HAP are regulated under section 112 of the CAA. Emissions from stationary engines contribute significantly to air pollution and cause adverse health and welfare effects. The pollutants to be regulated by the proposed NSPS for stationary SI engines are nitrogen oxides (NO
X
), carbon monoxide (CO), and non-methane hydrocarbons (NMHC). In addition, a sulfur limit on gasoline is being proposed.

Nitrogen oxides are listed as criteria pollutants and are regulated due to their contribution to the formation of ozone. Nitrogen oxides are precursors to ozone formation. Exposure to ozone has been linked to health and welfare impacts. Health and welfare risks include impaired respiratory function, eye irritation, deterioration of materials such as rubber, and necrosis of plant tissue. Nitrogen oxides are also a major precursor for nitrate PM. Particulate matter, also regulated as a criteria pollutant, is associated with premature mortality and a number of serious adverse respiratory and cardiovascular effects, especially in children, the elderly, and people with existing heart or lung disease. Particulate matter also reduces visibility and damages building materials. Nitrogen oxides are also associated with various other health and welfare effects. Nitrogen dioxide can cause irritation of the lungs and can also reduce the resistance to respiratory infection. Nitrogen oxides are one of the major pollutants emitted from stationary ICE and stationary ICE are considered to cause or contribute significantly to nationwide releases of NO
X
emissions.

Carbon monoxide is a criteria pollutant and is considered harmful to public health and the environment. Carbon monoxide has been linked to increased risk for people with heart disease, reduced visual perception, cognitive functions and aerobic capacity, and possible fetal effects. Stationary engines emit CO and are considered to contribute to several areas failing to attain the National Ambient Air Quality Standards for CO.

Emissions of NMHC from stationary engines contribute to the formation of ozone. In addition, emissions of NMHC include air toxics such as benzene, formaldehyde, acetaldehyde, 1,3-butadiene, and acrolein. These substances are known or suspected to be human or animal carcinogens, or having noncancer health effects such as irritation or corrosion of the eyes, nose, throat, and lungs; pulmonary and respiratory problems; and dermatitis and sensitization of the skin and respiratory tract. Stationary engines contribute to nationwide releases of NMHC emissions.

Sulfur dioxide (SO
2
) is a criteria pollutant emitted from stationary SI engines due to sulfur in gasoline. It contributes to respiratory illness, particularly in children and the elderly, and aggravates existing heart and lung diseases. It also contributes to acid deposition, damaging forests, aquatic ecosystems, crops, and building materials. Sulfur dioxide undergoes chemical reactions in the atmosphere to form sulfate PM. The health effects of PM were previously described in this section. This proposed rule reduces SO
2
and sulfate PM by requiring the use of gasoline with lower sulfur levels, thus improving air quality, public health, and public welfare.

The NESHAP being proposed in this action would regulate emissions of HAP. Available emissions data show that several HAP are emitted from stationary engines, which are formed during the combustion process or that are contained within the fuel burned. Many HAP have been detected from the stationary engine exhaust, but only a handful of HAP represent the majority of HAP emissions from stationary engines. These HAP are formaldehyde, acrolein, methanol, and acetaldehyde. We described the health effects of these HAP and other HAP emitted from the operation of stationary ICE in the preamble to 40 CFR part 63, subpart ZZZZ, published on June 15, 2004, on page 33474 of the
Federal Register
. These HAP emissions are known to cause, or contribute significantly to air pollution, which may reasonably be anticipated to endanger public health or welfare.

Under the RICE NESHAP, we are proposing to limit emissions of HAP through emissions standards for NMHC and formaldehyde. We have determined that it is appropriate to use NMHC and formaldehyde or CO emissions as a surrogate for HAP emissions. For the RICE MHAP promulgated in 2004 (69 FR 33474) for engines greater than 500 HP located at major sources, EPA chose to select a single pollutant to serve as a surrogate for HAP emissions. Formaldehyde is the hazardous air pollutant present in the highest concentration from stationary engines. In addition, emissions data show that formaldehyde emission levels are related to other HAP emission levels. For the NESHAP promulgated in 2004, EPA also found that there is a strong relationship between CO emissions reductions and HAP emissions reductions from 2SLB, 4SLB, and CI stationary engines. Therefore, CO emissions reductions were chosen as a surrogate for HAP emissions reductions for 2SLB, 4SLB, and CI stationary

engines operating with oxidation catalyst systems for that rule. For the standards being proposed in this action, EPA believes that previously made decisions regarding the appropriateness of using formaldehyde and CO as surrogates for HAP are still valid. For this proposal, EPA conducted an analysis using available emissions data to look at the relationship between formaldehyde (a surrogate for HAP) and NMHC. Based on statistical results of engine exhaust data, these data indicate that there is a significant relationship between formaldehyde and NMHC emissions from 2SLB, 4SLB, and CI stationary RICE. For this reason, EPA believes it is appropriate to use NMHC emissions as a surrogate for formaldehyde, and consequently, also as a surrogate for HAP emissions. Much of the HAP being regulated are hydrocarbons; e.g., formaldehyde, an oxygenated hydrocarbon, is the HAP emitted in largest quantities from stationary engines. For more information on EPA's analysis of NMHC as a surrogate for HAP, refer to the docket for this proposal.

C. What are the proposed standards?

A description of the proposed standards is provided in the following sections.

1. SI NSPS

a. Stationary SI Engines ≤19 KW (25 HP). EPA is proposing emission standards that will affect manufacturers, owners, and operators of stationary SI engines. Engine manufacturers must certify their stationary SI engines with a maximum engine power less than or equal to 19 KW (25 HP) that are manufactured after January 1, 2008, to the certification emission standards for new nonroad SI engines in 40 CFR part 90, as applicable. The standards applicable to these engines are shown in Table 1 of this preamble.

Engine manufacturers must certify their stationary SI engines with a maximum engine power greater than or equal to 500 HP that use gasoline or rich burn engines greater than or equal to 500 HP that use LPG that are manufactured after July 1, 2007, to the certification emission standards for new nonroad SI engines in 40 CFR part 1048. The standards applicable to engines greater than 19 KW (25 HP) that are gasoline or rich burn engines that use LPG are shown in Table 2 of this preamble.

For stationary SI engines greater than 19 KW (25 HP) that use gasoline and rich burn engines greater than 19 KW (25 HP) that use LPG, the technology that is the basis of the proposed standards are the technologies used by nonroad SI engines greater than 19 KW (25 HP) to comply with the emission standards in 40 CFR part 1048. The majority of nonroad SI engines greater than 19 KW (25 HP) use LPG, but some operate on gasoline or natural gas. There are two tiers for nonroad SI engines in this size category. Tier 1 standards were scheduled to begin in 2004; Tier 2 standards will begin in 2007. The upcoming Tier 2 standards are based on three-way catalyst systems with electronic, closed-loop fuel systems. For stationary SI engines greater than 19 KW (25 HP) that use gasoline or are rich burn engines greater than 19 KW (25 HP) that use LPG, EPA believes these engines are very similar to nonroad SI equipment, and the same engines designed for use in nonroad applications are used in stationary applications. Therefore, for stationary SI engines greater than 19 KW (25 HP) that use gasoline and rich burn engines greater than 19 KW (25 HP) that use LPG, the BDT is the technology that is the basis for the Tier 2 emission standards for nonroad engines above 19 KW (25 HP) regulated under 40 CFR part 1048.

The engine must be installed and configured according to the manufacturer's specifications to ensure compliance with the applicable standards. Owners and operators of engines that have been certified by the engine manufacturer are not required to conduct any performance testing unless the engine is operated outside of the fuel properties specified by the manufacturer. If the owner or operator uses fuels outside of the fuel specifications (other than propane used solely for emergency purposes for up to 100 hours per year) or does not follow the adjustments specified by the manufacturer, the engine is no longer considered a certified engine and the owner or operator must test the engine to demonstrate compliance, according to the procedures specified in § 60.4244.

(2) Conducting an initial performance test to demonstrate compliance with the emission standards specified in Table 1 to this subpart and according to the requirements specified in § 60.4244, as applicable. If you are an owner or operator of a stationary SI internal combustion engine that is greater than 500 HP, you must also conduct subsequent performance tests every 3 years or 8,760 hours of operation, whichever comes first.

(d) If you are an owner or operator of a stationary SI internal combustion engine that must comply with the emission standards specified in § 60.4233(e), you must demonstrate compliance according paragraph (c)(2) of this section.

(e) Emergency stationary ICE may be operated for the purpose of maintenance checks and readiness testing, provided that the tests are recommended by Federal, State or local government, the manufacturer, the vendor, or the insurance company associated with the engine. Maintenance checks and readiness testing of such units is limited to 100 hours per year. There is no time limit on the use of emergency stationary ICE in emergency situations. The owner or operator may petition the Administrator for approval of additional hours to be used for maintenance checks and readiness testing, but a petition is not required if the owner or operator maintains records indicating that Federal, State, or local standards require maintenance and testing of emergency ICE beyond 100 hours per year. For owners and operators of emergency engines, any operation other than emergency operation and maintenance and testing as permitted in this section, is prohibited.

(f) Owners and operators of stationary SI natural gas fired engines may operate their engines using propane for a maximum of 100 hours per year as an alternative fuel solely during emergency operations, but must keep records of such use. If propane is used for more than 100 hours per year in an engine that is not certified to the emission standards when using propane, the owners and operators are required to conduct a performance test to demonstrate compliance with the emission standards of § 60.4233.

Testing Requirements for Owners and Operators

This must include January 1 of the calendar year for which the model year is named. It may not begin before January 2 of the previous calendar year, and it must end by December 31 of the named calendar year. For an engine that is converted to a stationary engine after being placed into service as a nonroad or other non-stationary engine, model year means the calendar year or new model production period in which the engine was originally produced.

Natural gas
means a naturally occurring mixture of hydrocarbon and non-hydrocarbon gases found in geologic formations beneath the Earth's

surface, of which the principal constituent is methane. Natural gas may be field or pipeline quality.

Non-methane hydrocarbons
means the difference between the emitted mass of total hydrocarbons and the emitted mass of methane.

Other internal combustion engine
means any internal combustion engine, except combustion turbines, which is not a reciprocating internal combustion engine or rotary internal combustion engine.

Pipeline-quality natural gas
means a naturally occurring fluid mixture of hydrocarbons (e.g., methane, ethane, or propane) produced in geological formations beneath the Earth's surface that maintains a gaseous state at standard atmospheric temperature and pressure under ordinary conditions, and which is provided by a supplier through a pipeline. Pipeline-quality natural gas must either be composed of at least 70 percent methane by volume or have a gross calorific value between 950 and 1,100 British thermal units per standard cubic foot.

Reciprocating internal combustion engine
means any internal combustion engine which uses reciprocating motion to convert heat energy into mechanical work.

Rich burn engine
means any four-stroke spark ignited engine where the manufacturer's recommended operating air/fuel ratio divided by the stoichiometric air/fuel ratio at full load conditions is less than or equal to 1.1. Engines originally manufactured as rich burn engines, but modified prior to June 12, 2006 with passive emission control technology for NO
X
(such as pre-combustion chambers) will be considered lean burn engines. Also, existing engines where there are no manufacturer's recommendations regarding air/fuel ratio will be considered a rich burn engine if the excess oxygen content of the exhaust at full load conditions is less than or equal to 2 percent.

Rotary internal combustion engine
means any internal combustion engine which uses rotary motion to convert heat energy into mechanical work.

Spark ignition
means relating to either: A gasoline-fueled engine; or any other type of engine with a spark plug (or other sparking device) and with operating characteristics significantly similar to the theoretical Otto combustion cycle. Spark ignition engines usually use a throttle to regulate intake air flow to control power during normal operation. Dual-fuel engines in which a liquid fuel (typically diesel fuel) is used for compression ignition and gaseous fuel (typically natural gas) is used as the primary fuel at an annual average ratio of less than 2 parts diesel fuel to 100 parts total fuel on an energy equivalent basis are spark ignition engines.

Stationary internal combustion engine
means any internal combustion engine, except combustion turbines, that converts heat energy into mechanical work and is not mobile. Stationary ICE differ from mobile ICE in that a stationary internal combustion engine is not a nonroad engine as defined at 40 CFR 1068.30, and is not used to propel a motor vehicle or a vehicle used solely for competition. Stationary ICE include reciprocating ICE, rotary ICE, and other ICE, except combustion turbines.

Stationary internal combustion engine test cell/stand
means an engine test cell/stand, as defined in subpart PPPPP of this part, that test stationary ICE.

Stoichiometric
means the theoretical air-to-fuel ratio required for complete combustion.

Subpart
means 40 CFOFR part 60, subpart JJJJ.

means the combined mass of organic compounds measured by the specified procedure for measuring total hydrocarbon, expressed as a hydrocarbon with a hydrogen-to-carbon mass ratio of 1.85:1.

Two-stroke engine
means a type of engine which completes the power cycle in single crankshaft revolution by combining the intake and compression operations into one stroke and the power and exhaust operations into a second stroke. This system requires auxiliary scavenging and inherently runs lean of stoichiometric.

Useful life
means the period during which the engine is designed to properly function in terms of reliability and fuel consumption, without being remanufactured, specified as a number of hours of operation or calendar years, whichever comes first. The values for useful life for stationary SI ICE with a maximum engine power less than or equal to 19 KW (25 HP) are given in 40 CFR 90.105. The values for useful life for stationary SI ICE with a maximum engine power greater than 19 KW (25 HP) certified to 40 CFR part 1048 are given in 40 CFR 1048.101(g). The useful life for stationary SI ICE with a maximum engine power greater than 19 KW (25 HP) certified under the voluntary manufacturer certification program of this subpart is 8,000 hours or 10 years, whichever comes first.

Voluntary certification program
means an optional engine certification program that manufacturers of stationary SI internal combustion engines with a maximum engine power greater than 19 KW (25 HP) that do not use gasoline and are not rich burn engines that use LPG can choose to participate in to certify their engines to the emission standards in § 60.4231(d).
