   Appendix B.  Ozone Formation

                This appendix provides a brief explanation of the process by which ozone is
   formed, followed by a list of other sonrces expanding on the role of NO^ and VOCs.
         The prediction of ozone (Q3) levels and the development of control strategics for
   ozone have been complicated by the fact thai ozone is not directly emitted. Rather, it is
   formed In the lower atmosphere in [he presence of sunlight through a complex series  of
   reactions between volatile organic compounds (VOCs), oxides of nitrogen (NO^), and ambient
   oxygen  The concentrations of ozone and its precursor? are dynamic and nonlinear. Thus,
   ozone concentrations are not necessarily additive, but depend on the concentrations of all
   compounds involved in atmospheric chemistry.  VOCs ore emirted by anthropogenic winces,
   such as evaporation of gasoline and solvents, and by biogenk sources such as vegetation,
   Individual VOC species differ widely in their capacity to gene raze ozone.  NOX is formed
   primarily by  combustion processes and can contribute to either the creation or destruction of
   ozone, depending on die amount of VOCs present.
         Ozone is produced when aiomk oxygen (O) reacts with molecular oxygen (GO  in this
   reaction;
                       O + Oj + M-»O, + M

   where M is a third body that removes the energy of the reaction and stabilizes the  O,
   molecule. The atomic oxygen necessary for this reaction is produced primarily from the
   photodissocUiion of NO2, according to this reaction:
                          j + hv -> NO + O
   The photon (hv) in this reaction is in dtt blue-violet end of ihe visible spectrum which, when
   absorbed, produces a brown color.  This is why a brown haze is associated with ozone

   pollution, even though ozone Use If is a colorless gas.  In the above reactions, NOX is involved
   in creating ozone.
          However, in the absence of other reactants, the ozone and nitrogen oxide (NO)
   produced in these reactions will combine to form nitrogen dioxide and molecular oxygen:

                        NO + O, -> NO2 + Oj

   Thus, oxides of nitrogen participate in both die creation of ozone and can retard creation of
   ozone.  Put another way, in isolation equilibrium concentrations of ozone, nkrogen dioxide,
   and nitrogen  oxide coexist. However, in the presence of organic peroxy radicals (RO2),
   which are formed by  the reaction of hydraxyi  radicals (OH) with VOCs, nitrogen dioxide can
   be regenerated from nitrogen oxide without consuming ozone, as in this reaction;

                        RQi + NO -* NO, + RO

   Thus, the presence of VOCs in the atmosphere is crucial to allowing ozone to accumulate,
   instead of allowing ozone to stabilize at a relatively low concentration dictated by the
   equilibrium of NO and NQj-  Generally speaking, the presence of more organic peroxy
   radicals wfll  allow more ozone molecules to persist in the air,  The number of organic pero*y
   radicals formed from  a single VOC varies, and tho* the photochemical reactivity of VOCs
   varies,

   Appendix G. Emission Inventories Developed Using SIP and CARB Data

         As EPA begin its study of nonfood emissions, one of ihe most comprehensive sources
   of data already available were emission inventories developed for State [mplementHtiort Plans
   (5IPs). EPA considered existing draft emission inventories developed by  stales in 1987 SIPs
   and recent inventories developed by ihe California Air Resources  Boom* (CARB) for their
   SIPs.  SIPs from eighteen geographical areas were used, aa were CARB analyses for seven air
   basins in Califomia.  Table G-Ql provides a list of these areas,

          Certain genps and inconaiatencies, as well as ouuiated emlision fectora, in the SIP

   and substituted new erniision fietOT in older to generate new inventories bised on die SIP
   data.  The emission inventories developed by CARB for nonroad  mobile sources were much
   more detailed tlian those from the SIPs, sod were summarized without revision by EPA,

              following section describes in greater detail the data obtained from SIPs and the
   methodology used in creating; the inventories using this data.

          SH*-Bas«d Activity Levels

          Emission inventories arc developed as part of Stale Implementation Plans, or 5IPs,
   which are submitted periodically to EPA by areas dial do not comply with NAAQS.  SIPs
   themselves  outline means by which stale authorities plan to meet the NAAQS.  Generally.
   this includes a plan for emission reductions, which are projected based on the baseline
   emission inventory.  Stare air quality planners  generally develop emission inventories for
   nonattainmeni areas  following the methodologies outlined in the existing EPA guidance,1
          EPA provides infarmaticm on preparing emission inventories for SIPs In a series of
   five documents entitled Procedures for Emission Inventory Preparation (henceforth simply
   Procedures).  The fbsi volume gives an overview of the methodologies and reporting
   requirements for emission inventories and subsequent volumes give the methodologies
   whereby activity levels may be estimated at the couniy level for point sources,1 nonroad and
   highway mobile sources,* and other area sources.*  Although all mobile sources an a
   subcategory of area  sources,  the tenn "mobile  source" was often used in oaai SIP emission
   inventories  to refer solely to  highway vehicles. Emissions from all other mobile sources are,
   in such cases, often  reported aa "off-highway mobile sources" In  the area source inventory,
   This 13 likely due to die fact that highway vehicles art already regulated and therefore  much
   better characterized  dun nonroad mobile sources.  Abo, nonroad mobile source activity is
   often more  similar to thai of other area sources than ii highway vehicle activity.  For
   example, construction equipment activity can be characterized by considering the construction
   industry emplovmem during  die inventory period.  Similarly, fuel consumption (e.g. lie a ting
   oil) in commercial and J&dumial applications may be estimated using  employment statistics in
   the  applicable industries, Where po&aible, die emission facton in die EPA guidance
   document were updated  to include more recent daia. A full discussion of th* development of
   revised SIP emission factors is contained In Appendix I.
FINAL - Novwnber i?5H

Nonroad Engine ant Vehicle Emission Study
          After activity levels for die various source types have been estimated, emission
   factors* must be applied to calculate emissions in mass per unit time for each of die
   pollutants being studied in ihe inventory area-
          Inventories developed for SIPs are usually developed for a given base year (BY);
   hence emissions are expressed in tons per year (tpy).  Li areas where nonartainment is a
   seasonal problem, the inventories may also  be tempo rally adjusted. In many areas, ozone
   nonattainmem is predominately a summertime problem: therefore, emissions of ozone
   precursors are expressed in tons per summer day (tpsd).  Similarly, because CO nonanainmem
   is usually a  wintertime probEem,r CO emissions are often expressed in tons per winter day
   (rpwd).  In its analysis of SIP emission inventories, EPA used those seasonal adjustments that
   were reported in due SIPs,
          For this study, EPA has examined several of ihe draft SIP inventories developed by
   states for ihe 1987 and 1988 BY.  Because of ihe CAAA requirement thai states develop
   emission inventories  for the 1990 BY, many of die 1987/1988 draft inventories have not been
   finalized ar  this time.  However, because the  1990 BY inventories will not be completed in
   1991, only die earlier inventories may be considered for this study, despite die fact  mat they
   are still in draft form.
          In analyzing 1987  base year emission inventories from SIPs, EPA extracted  ihe
   activity levels calculated for nonroad engines and vehicles.  Because the activity levels were
   separated from the emission factors, it wa» possible to apply ihe emission factors developed
   as pan of mis study to the activity levels to develop revised emission inventories thai have
   benefitted from improvementa to the emission factors.
          In adjusting die SIP emission inventories for seasonal activity variations,  EPA
   determined  what assumptions had  been used in di* original inventory and applied only those
   having to do with seasonal variations.  Consequently, dtese seasonal temporal  adjustments are
   different from those mack in inventories that also considered day-to-day activity fluctuations
   or daily temporal adjustments.

         Summaries of the analysis of SIP emission inventories are given in the following
   tables.  Detailed results of the SIP emission inventories are given in State Estimates of
   Norwood Engine and Vehicle Emissions* which documents for each nonaitainment aiea
   studied the nonroad engine and vehicle activity levels derived, the emissions calculated, and
   the emissions from ether sources (i.e., highway vehicles, other area and point sources).
         Emission inventories prepared by the CARB are considered separately because
   inventories for some nonfood mobile source categories have recently been developed  by
   CARB in support of California's proposed regulations applicable to such sources. These
   emission inventories are generally more refined than those that hove  been developed  by states
   following the existing EPA guidance.  Furthermore, they use different nonroad mobile source
   categories and arc, therefore, not directly comparable to die draft SIP inventories.
         Because of these differences from die SIP-based inventories, data from California's
   nonroad mobile source emission inventories were used as provided and compared to  the
   highway and other source emissions given in the March  1990 version of the 1987 emission
   inventory prepared by CARB.  The nonroad mobile source categories for which CARB has
   recently developed emission inventories are; utility and lawn and garden equipment,* heavy-
   duty farm and construction equipment,7 and commercial  marine  vessels.* *  These
   inventories are also summarized in the following tables.

   Appendix I,   Ezmsadan Factor Development

          This appendix details the origins of the emission factor? used to calculate emission
   inventories for this study.
          For this  study, emissions from internal combustion engines an broadly grouped into
   one of four source categories baaed on  the origin of che emission:  tailpipe exhaust, refueling,
   evaporative, and crankcaie emissions.  Each of ibose categories is further divided by
   pollutant:  HC,  CO, NO^, and other toxic pollutants including paniculate marter, aldehydes.
   SOX, benzene, and 1,3-butadiene.  Since refueling and evaporative emissions BIT not a
   function of combustion, but air a function of fuel evaporation, only hydrocartmi emissions
   are considered for refueling and evaporative emissions. For each source category, pollutant,
   and nonroad eqotpment type (including fuel type and operating cycle), an emission factor is
   necessary to construct emission invetuorieg. In simple terms,  the emission factor is a measure
   of the cane at which a particular type of equipment emits a particular pollutant under normal
   operating conditions.
          The remainder of this appendix  describes how tailpipe exhaust, refueling, evaporative.
   •nd cTonkcase emission factors were developed.  Adjustment!! were mad* to new engine
   emission factors DO account for  in-usc effects and test cycle (steady slate vs. transient) effects
   when; appropriate.  These  adjustments  are discussed In Chapter 2 of inia appendix. Emission
   factors for pamculate matter, aldehydes, and SOX which were not  available  from the primary
   data sources described  below were taken bom AP-421 or from irto« recommended by
   Southwest Research Imtiiute ($wRI).*  Emission rates for nitrosamines, benzene,  and 1,3-
   butadkn* are discussed ki scparwe chapters at the end of rhii appendix. Gasoline vapors are
   discussed in DCftna of the refueling and evaporative emissions.  The emission factors used for
   calculating the SIP inventories an presented in Table I-01 and dime used for calculating
   Inventories A and 8 arc in Table 1-02,
          Tables I 01 through 1-17 are located at die end of the appendix.

                       Chapter 1.  Tailpipe Exhaust Emisaioa Factors

          A dbcuiium of the development of tailpipe exhaust emission factors used in this study
   is presented below for the following categories; lawn and garden equipment, agricultural
   equipment, construction equipment, Logging equipment, industrial equipment, light commercial
   equipment, recreational marine, commercial marine vessels, recreational equipment, and
   airport service equipment,

   1.1.   Lawn ami Garden Euiment
          1.1,1,
          The primary data source used in deriving die emission factors for gasoline lawn and
   garden equipment was the California Air Resources Board (CAJRB) technical support
   document (TSD) for Lawn and garden equipment/ The testing done for CARB was
   performed by manufacturers, Southwest Research Institute (SwRI),4 and Hekten Associates'
   far die Portable Power Equipment Manufacturers Association (PPEMAl The tost results
   represent the most up-to-date information available for this category which were aggregated
   into emission factors.
          The emission factors for calculating State Implementation Plan (SIP) emission
   inventories required aggregation of the CARB data  imo a 4-stroke category and a 2-stroax
   category. The CARB data was weighted by the population horsepower houfi data submitted
   to EPA by the Outdoor Power Equipment Institute,  the Portable Power Equipment
   Manufacturers Aasociaikm and by data contained in the Heiden report.  Table* 1-09 and 1-04
   show this aggfefarioD for 4-*trofce and 2-stroke equipment respectively.  To be used in
   computing SIP emission inventories, ii was neceasaiy to convert the emission factoii from
   units of g/hp-hr to a/gallon fuel consumed.  Brake specific fuel consumption (BSFC) values
   shown in Tables 1-03 and 1-04 were used for die conversion,  The origin of the** values is
   also shown in the tables.  All aldehyde emission factors wens derived from 5AE Paper
   91Q56Q, "Emiision Factora for Small Utiliry Enfines."6

       The emission factors necessary for calculating Inventories A and B also required some
aggregation, although not to (he extent necessary for Lhe SIP inventory calculation  The
derividon of these emission factois is shown in Table 1-05,

       1.1.2. Diesel
       Nearly ill lawn and garden equipment is powered by gasoline engines.  However, a
small population of rear engine riding mowers, lawn and garden tractors, and wood splitters,
chippera/sfump grinders,  and commercial turf equipment are powered by diesel engines.
Since no emission data is available far diesel-powered lawn and garden equipment, the
emission factors for dicsel light commercial equipment (< SO hp) were assumed to be the best
approximation and wexe used for the study (see "1.5. Light Commercial Equipment < 50 hp").

1*1.   Agricultural Eooittintnt & Conatniction Eqqjpimni

       1.2.1. DfestJ
       The moat recent, up-to-daa published emission factors for agricultural and
construction dkwl equipment aie reported In the CAL/ERT report,7 and in a recent report to
CARS by Energy and Environmental Analysis (EEA)1 on heavy-duty construction
equipment.  In general, the emissions for the C ALBERT repoit were measured on a 13 -mode
steady  stale cycle and emission f acton an reported in terms of equipment types. The EEA
report presented general emission factors for HC, NO, and pamculate matter by model year.
       In addition to these two source*, the Engine Manufacturers Association (EMA)
submitted to EPA a liit of recommended emission facnm for dksel construction and
agricultural equipment presented In Table 1-06. The emission data was based on individual
engine manufacturer submissions of emission data obtained from Lhe 8-Mode Emission Test
Procedure (ISO SI78) and related mode weighing factors.  The emission factors were EMA's
beat estimate* of in-the- field Ekd  population weighted factors.  For agricultural equipment,
EMA provided factors for only three equipment types (i.e. faim tractors, grain combine, and
conon pickers).
       In general, the emission factors leponed by the three sources are reasonably similar
For agricultural equipment, EPA tuu selected the factors presented in the CAL/ERT study

    sinoe they are presented by specific equipment type.  Fqr the SIP inventories, the emission
    factors were aggregated to tractor and nontraerar categories by the energy outputs reported in
    the CAUERT report.  The factors were convened from units of g/hp-hr to Ih/lQQO gallons of
    fuel consumed by using a BSFC  of 0.4 lb/Hp-hr9 and diesel fuel density of 7J ft/gallon.I0
    Table 1-08 shows ihe aggregation of the emission factors in termi of gflrp-hr, while
    Table 1-08 shows the lb/1000 gal deri¥Htion.
          For construction equipment the EMA emission factors were selected to be used to
    calculate emission inventories. For some equipment types, EMA factors were not available.
    In these ewes, the Fourth Edition of AF-42" factors which were derived Crom CAUERT11
    factors were used.  Table 1-9 compares the AP-42 (CAL/ERT) and EMA emission factors for
    construction equipment.
          The EMA did not report emission factors for paniculate maraer.  The emission factors
    for paniculate matter and aldehyde* used in the study for Inventory A ate those reported in
    the Fourth Edition of AP-42.  The test remits from a recent joint EPA/toduitiy program to
    assess test cycles for nonroid equipment are presented in Table I-10.  The paniculate
    emissions from the four 1991 diesel nonfood engines tested suggest that these newer engines
    have considerably lover emission ran thin the emission facton reported in AP-42 (which
    are derived from a 1973 Southwest Research Institute study)13.  Particulate  emission rotes for
    the four new engines tested an two to five times lower than  the emission factors used for
    inventory purposes.  Therefore, as the older engine fleet i» replaced by the  newer engines
   whkii emit lower levels of particulate matter, the paniculate  emission inventory will decrease
    accordingly*  Although, the emiMton factors rcpxnted in AP-42 are aaaumed by EPA to be
   more represeniaiive of the ivcnge engine in the population, the lest results on new engines
   suggest thai these emission facloa may overeatimaM  particulore ernusion rarea. To  some
   extent, technology knprovcmedts in highway engines 10 meet the paniculate emission
   standards (beginning in 198A) may h*vv been carried into nonroad versions of these engines
   with the accompanying paniculate emission benefit.  Also, the data from the EPA/Industry
    program indicate that engine manufacturers who do not produce engines far highway
    appticationi have shown a decrease in paniculate levels from 1973 to 1991.
          The Engine Manufacturers Association (EMA) expressed concerns regarding the
    representativeness of the AP-42 data which was generated in 1973. As a result, the

   particulaic mairer emission factors used for Inventory 1 are the equally weighted average of
   the AP-42 emission factors and the 1991 EPA/Industry average 8-mode nonroad engine test
   data

          1.2.2.  Gasoline
          The emission factors for gasoline agricultural and construaion equipment selected to
   be used in calculating emission inventories are from the Fourth Edition of AJM2, The other
   sources thai reported emission factors for dieael equipment did not report gasoline equipment
   emission facton. The CAL/ERT report did suggest using 2,8  g/hp-nr HC, 163 g/hp-hr CO,
   and 7,S g/hp-hr NO^ for gasoline powered equipment (Tables  I-7(c) and I-8(c))<  However,
   the emission factor* in AP-42 are more specific to equipment type and  will be used for the
   study.
          The particnki* emission factors in  AP-42 wen derived from paniculate measurements
   on gasoline nonfood engines at SwRI in Lho mid-seventies.1''  Leaded gasolines which
   generally contained between 1.5 and 2 grams of lead per gallon were used for the emission
   tests.  This high lead  fuel is not commercially available today. Even today's  leaded hiel
   contains very little lead.  Since panicle* consisting of lead oxides are the main paniculate
   emission from leaded-gasoline fueled engines, the AP-42 emission factors am not
   representative of emission rates from equipment operating on currently available gasoline.
   Therefore, the values repotted in AP-42 were not uacd in thia  study.  Instead, a value of
   1.64 lb/1000 gallon] waa used for the paniculate emission factors for gasoline fueled
   equipment This value is based on a recommendation from SwRI In the Nonfood Emission
   Factors cf Air Tcyrief1* repon to EPA.  Where necewaiy, the  1.64 lb/1000 gallon was
   convened  to 0,06 g/hp-hr by assuming BSFC 0.5 Ib/hp-hr1*  and density of gasoline of
   6.2 Ib/gBllon,IT  Aldehyde emission facrois were token from AP-42.

         The diesei emission factors for log skidd ers submitted to EPA by EMA (Table N-6)

   1.4.   Industrial Equipment

         Emission factors for gasoline and diesei industrial equipment used for the study arc
   ihose reported in Volume I of AP-42. These factors were derived by SwRl in 1973" and
   were based on teats performed on eight diesei engines and foul gasoline engines. Ho
   emiisk™ data were available for LPG-powered aerial lifts, foifclifla, and iweepers&crabbers.
   The only emission dolt found foe LPQ-poweied equipment is front two gasoline engines
   which were convened to operate on LPQ, One engine was a 4,5 hp overhead valve walk
   behind mower engine tested by Southwest Research Institute.30  Compared to the emisiions
   when the engine was operated on gasoline, the engine emiRed 38% kss HC, 55% less CO,
   147% more NOX, 13% leas FM, and approximately the same level of aldehydes when
   operated on LPG.  The other engine was  z 12,5 hp utility engine tested by Onan*1
   Compared to operation on  gasoline, this engine emitted 72% leu HC, 80% less CO, and
   347% more NOj. when operated on LPG. Since neither of these engines nc represenrative of
   the larger industrial ecruipniBnt engines, the emission dou cannot directly be oatd for
   developing an eraiaaon factor.  However, the relative differences between the gasoline and
   LPG emission ranlta for the two engines can be naed to approximate the LFO emission
   factor.  The above percentages were averaged resulting in a 35% reduction in HC,  a 68%
   reduction in CO, a 247% increase in N(\, and a 13* reduction in partiruiate matter
   compared to the gasoline baseline emi;,sion value? when an engine b operated on propane,
   These percentages were applied to the gasoline emission factors to appfoiimaie the LPG
   emission factors.

   compressors, welders, and pressure washers.  The emission factors recommended by SwRI':
   for the continuous service die5*1 equipment will be used for the study.  These factors are (he

   commercial equipment to be used in die study are  taken from the CARB technical support
   document for utility and lawn and garden equipment2* for large engines.  Engines  tested to
   develop ihe targe engine emission factors included a 16 hp single cylinder aide valve engine
   and two 18 hp 2-cyUnder tide valve engines.  No emissions data were available for LPG
   powered pumps and gas compressors.  Therefore, the gasoline emission factors for these
   equipment types were decreased by  55% for HC, decreased by 68% for CO, increased  by
   247% for NO** and decreased by  13% for particulate matter to approximate the LPG emission
   f acton.  This methodology is discussed in "1,4, Industrial Equipment" above.

   1.6.   Recreational Marine

         1.&1.  Outboard Moion
         The emission factors for outboard motors used in the study are derived from  data
   submitted to GPA by the National Marine Manufacturers Association (NMMA}. Data  were
   submitted for [weary-five 2-stmkt outboard engines  ind three 4-itrake outboard engines
   tested using ihe International Counsel of Marine Industry Associationa (ICOM1A) Standard
   Ho, 36-58 duty cyck.u  To aggregate me- HC, CO, and NOX emission factors on a national
   level for 2-stroke outboard engines, the horsepower distributions for the eight areas of the
   Bran survey10 were used. The brake specific emission data supplied by NMMA were
   grouped into die horsepower ranges consistent with the Bnjh survey and averaged within each
   range.  These dam were then combined ia shown  in Table 1-1 la using the survey
   distributions.  The resulting emission factors are in fuel based unio (grams/gillon).  The 4-
   stroke outboard emission dfflft supplied by NMMA were aggregated as  shewn in Table l-{ I b
          Paniculate mazier, aldehyde, and oxides of sulfur emissions were not measured from

   for 2".stroke) emission factors for noncualyst gasoline engines recommended by Southwest
   Research Institute (SwRl)37 were used. For 2-stroke outboards, no data on particular
   emission rates was available. The paniculate emission faetoia for 2-moke utilliy engines of
   7.7 g/hp-hr from ihe CARS technical support document for utility and lawn and garden
   equipment were used to approximate rates for outboard engines.34 A brake specific fuel
   consumption value of 0.16 gallon/hp-hi was calculated from data supplied by NMMA and the

       Very little data exists on emission races from snowmobiles. The best currently
available published data appeals to be contained in AP-42. These emission factors were
derived from testing performed by SwRI in 1974"  and are being considered for the study.
The factors in terms of g/hr wen  converted to g/hp-hr for use in calculating emissions
inventories  from the activity information provided by EEA.  The power reported by SwRI for
the various  test  engines was weighted in the same manner as the emission values to determine
a composite power of 5.8 hp over die teat cycle.  The g/hr value was then divided by 5.8 to
determine g/hp hr.  In a recent response to CARD mail out #90-70 entitled A Proposal to
Establish Exhaust Emission Standards and Test Procedures for Off-Highway Ligfit-Dury

   2.1.   Adjustment! for Test Cycle
         To develop emission  factors representative of in-yje nonroad engines, the test cycle
   thai the  engines are operated on should simulate typical in-use operation. There is much
   debate regarding the appropriateness of using a steady stale test cycle or a transient test cycle
   for emission testing nonfood engines.  A steady state test is a series of fixed set points of
   speed and load held for a period of time (usually from two to ten minutes).  Emission
   measurements in made at the end of the period when readings have stabilized. Currently, a
   transient cycle is used to certify heavy-duty highway engines,  It is a continuously varying
   cycl* of speeds and loads which may have brief periods of steady state operation. Emission
   meaiurafienia ace made continuously over all points.
         The emisaion factors  submitted by EMA for nonroad equipment were based on data

   2.1.   Ad fast meats for la-Use Optra t ion

          The emission factors contained in Tables I-02a, 1-02 b, and I-02d were developed using
   daia from testing new engines, Although many of the test procedures used for emission
   testing required an engine break-in period, the tests performed cm new engines do not account
   for in-use impacts on emissions from engine malfunctions, improper maintenance, and engine
   wear. To assess the magnitude of these impacts, EPA conn-acted with Southwest Research
   Institute (SwRT) to emission test small in-une utility engines. EPA also used exulting daia on
   pie-controlled heavy-duty engines to estimate in-use impacts on emission factors.
          Southwest Research InirtiraK procured five in-use utility engines (three 4-stroJp;
   engines and cwo 2*icroke engine*) and performed emission tests using the 5AE 11088
   procedure. A description of the engines and the emission lot results are shown in Table I~14,
   The table also shows the emission factors used for the respective equipment rypes which were
   derived from  new, properly operating engines. The ratio of the in-use engine  test emissions
   to the new engine emission factor u also shown in the cable  and  these values were averaged
   to determine an in-iue adjustment factor which can be applied to new engine emission
   factors.

          The 4-stroke engines team) by SwRI showed 2,1 times  the HC emiflsiona, 1.9 times
   the CO emissioiw, 0.4 times the tiO^ emusiona, and 3.6 times the panicwlate  emissions of
   new engine emJastms (Table 1-14). These engines exhibited problems of low power, head
   gasket leaks and others which are described in the SwfiJ report." Although only & very
   small sample  of 4-stroke engines were tested,  the  trend of high HC, CO, and pairktilates and
   low NO* was cons latent. Thus, the adjustment factors were  applied to  the emission  factors of
   gasoline 4-srroke engines lew than 20 hp. The resulting emission factors (Table I-02e)
   represent a rough approximaiion of in-use nonfood engine emission levels.

              .  4-Sfroke Gasoline Engines Over 20 hp
         In 1983, the Engine Manufacturer Association (EMA) and the EPA conducted a joint
   in-uae test program to develop in-iise emission factors for heavy-duty diesel and heavy-duty
   gasoline engines, The program used 1979 and 1982 model year pie-controlled engines and is
   the best available source of data for rt present ing in-use nonroad engine emissions   Using this
   daia, a linear regression analysis was performed and the emissions as a function of mileage
   wai plotted. To estimate the in-ose adjustment factors some brood assumptions were made,
   Typical in-use engines were assumed to be have accmnulMed 55,000 miles, which is half of
   the useful life of 110,000 milts defined in the regulations far heavy-duty highway gasoline
   engines. The regression analysis won ihcn used to calculate an in-use factor by dividing the
   emission value ai 55,000 miles by that  ai 0 miles. The resulting factor? of 1.5 for HC and
   1.3 for CO wen applied to (he emission factors of gasoline 4-stroke engines over 20 hp 10
   approximate in-use emission factors (Table I-OZc),  The NOX emissions allowed no significant
   change with mileage accumulation and therefore NO* emission factors were not adjusted.
   Particulate 4-strok* engine emission facton were not adjusted since no data was avaiJobie.

         2.2-X  1-Strok* Gasoline Engine!
         As discussed above, SwRl tested two 2-stroke in-uae engines,  One was from a walk
   behind mower (WBM) application and the other waa from  a string trimmer application.  The
   eleven year old  WBM engine exhibited HC, CO, and PM emissions similar to the new engine
   emission f acton shown in Table 1-14.  This engine produced iomcwhai higher NOX emission
   than rhe new engine factors show.  The string trimmer engine, on the other hand, showed
   txtremely high HC, CO, and PM levels and similar NOX level* compared to the new engine
   emission nvrtors. Since only two data  points were available for 2-stroke engines and these
   data were widely divergent, EPA. did not estimate in-use adniicment factors based on these
   points. Instead, the factors used for 4-stroke engines less rtwi 20 hp  wen: used for HC and
   CO emiilions far 2-rtroke engines with average horsepower less  than 20, m the 2-stroke data
   bracketed the 4-stroke results for these pollutants (i.e., one data point was much lower and
   one waa much higher). The  4-stroke NO^ tdjusiment factor of 0.4 did not sewn appropriate
   to apply GO 2-smkea since both the 2-stroke engines Bested by Swll showed nearly equal of
   higher emission levels than new engine emission factors. Therefore,  no  adjustment was made

FINAL - Menmnbet I9il
-------
   to NOS new engine emission facton.  Also, the 4-stroke particular adjustment factor of 3 6
   did not seem appropriate since the new engine emission factor used as numerator of the factor
   ratio  was very small compared to the new emission factor value for 2-sirpke engines.
   Therefore, no adjustment was made to the Z-siroke paniculate new engine emission factor.
   For 2-srroke engines with average horsepower greater than 20, the adjustment factors for 4-
   strokcs greater than 20 hp were used.
          For 2-stroke outboard marine engines, these adjustments for HC and CO emissions
   would likely  overstate in-use effects due to the more unique characteristics of these engines,
   Outboard engines are built to be more durable than die smaller, less expensive utility/lawn
   and garden engines, and to operate in environments where air borne dust and din are less of a
   problem.  Tnereibre, an adjustment factor of 1-2 was applied to HC and CO for 2-stmlce
   outboard engines.
          The National Marine Manufacturer Association suggests that infuse adjustment factors
   for 2-strok* outboard engines should not be included in the calculation  of emission
   inventories until further investigation can be done. NMMA states that 2-stroke engines do
   not exhibit the same deterioration in efficiency after extended use as 4-stroke  engines and thai
   boaters are more likely to maintain their engines for safety  reasons.  Also, an NMMA
   member company recently compiled data on an &-honepower, 2-stroke outboard that had
   accumulated 2,500 hours on the company's durability cycle which showed no incteaae in
   specific emission.  However, EPA expects that using new engine emission factors for
   calculating in-use inventories would undentate actual in-use emission levels.  The in-use
   adjustment factors for 4-BtmkE gasoline engines greater than 20 hp were adjusted downward
   by a factor of about 2 as en estimation of the in-use adjustment for 2-stroke outboard engines.
   For the in-use estimate, an adjustment factor of 1.2 was applied to HC and CO for 2-stroke
   outboard engine emission factors.

          1.2,4.  DtaeJ Engine
          Aa discussed earlier, EMA and EPA conducted a joint program to assess the emission
   factors of pie-controlled heavy-duty diesel and gasoline  engines.  For diesel engines, the dara

   summaries of how refueling and evaporative emission factors were calculated for gasoline and
   diesel fueled equipment, rcsprctivdy.
          This  chapter is divided into four sections that (1) introduce die concept of refueling
   and evaporative emissions, (2) present fuel tank volume data, (3) present refueling emission
   factors, and  (4) present evaporarivt emission factor.  Fudi tank volumes are discussed
   separately to avoid duplication of discussion in die sections on refueling and evaporative
   emission factor methodology and data.

   3.1,    Concents of Refueling and Evaporative Emissions

          The concepts of refueling and evaporative emissions are now presented.  These
   tMtecpts we applicable to both gasoline and diesel fueled equipment (although perhaps more
   pertinent to gasoline fueled equipment than ditael  fueled equipment).

          3.1.1. Refudlnf Emfeethma
          There are two components of refueling etnliiiom:  spillage and vapor displacement,
   Spillage etniasiooa, or ninety spillage, arc those emiasiona that result from fuel spilled during
   die refueling process.  For example, spillage includes those vapors generated from fuel spilled
   while filling a Mange container from a gaa station pump and vapors generated from fuel
   spilled while traosferring the fuel from the storage container to die equipment.  Vapor
   displacement emisakms, or displacement, are those emissions that n-sult from displacing fuel
   vapors in die fuel tank of storage container with liquid fuel.  For example, if one gallon of
   gasoline is poured into a container which already contains some gasoline, one gallon of fuel
   vapor is displaced to rhe atmosphere by die incoming fuel.  For the purposes of diis study,
   only fuel tojr white refueling tht equipment Is considered.  One would expect, however, that
I-16                                                                       FINAL - November

   refueling emissions from the refueling of storage containers would be on the same order of
   magnitude as the refueling emissions from equipment.

          3.1.1. Evaporative Emissions
          Evaporative emissions are losses generated  by the evaporation of unbumed fuel.
   Evaporative  emissions do not pass through the combustion chamber,  Ralhrr, the primary
   sources of evaporative emissions are the carburetor and fuel tank. Similar to their on-road
   counterparts, evaporative emissions from nonroad sources can be subdivided inio four groups:
   hot soak, diurnal, running loss, and resting loss emissions.  Each category  accounts for
   emissions during specific operating conditions of the equipment and specific mechanisms  of
   emission.  Hot soak emission! are chose emissions which occur after die equipment has been
   turned  off and are  attributable to the elevated temperatuie of the equipmenr (e.g,, evaporation
   from the carburetor bowl).  Diurnal emissions aie those fuel vapors which occur while Uic
   equipment is not operating and are attributable to natural changes in ambient conditions
   (temperature, pressure, etc).  In addition, diurnal losses DCCWJ only during those portions of
   the year when  the equipment is used relatively regularly (every few days),34  Running loss
   emissions are those emissions which do not pass through the combustion chamber while the
   source is in operation.  Resting loss  emissions are those emissions that are not alieady
   identified by another category. For example, emissions which are due to permeation of fuel
   through fuel lines and fbel tank, and leakage in the fuel system arc resting loss emissions.
   For the purposes of this study, only  diurnal emissions will be considered due to the lack of
   data for hot  soak, resting loss and running lots emissions from nonroad engines,

   3.Z.   Dcrrioping Effective Fml Tank Volumes

          This  section will present those data and assumptions which were used to arrive ai
   effective fuel tank volumes for gasoline and diesel equipment.  Fuel tank volumes are not
   discussed with the presentation of other data to avoid tedious duplication of discussion,  Both
   evaporative and refueling emission factors use fuel tank volumes  as part of their calculation.
FINAL - November 1991

         This section, Developing Effective Fuel Tank Velxmes, is divided into two subchapters
   The first subcUapter presents effective fuel tank volumes for fasoiine equipment and Hie
   second subchapoer presents effective fuel tank volumes for diesel equipment.

         3.2X  Gasoline Fael Tank Volomes
         Data used to calculate gasoline fuel tank volumes may be broadly categorized into two
   groups: data supplied by manufacturers and manufacture re* sales brochures, and data
   geneiaied by EPA.  Effective fuel tank volumes dewed from each of these awuicea are
   discussed below.

         Manufacturers' Gasoline Fod Tank Data — Manufacturer! were asked to supply
   fuel tank volumes for severed pieces of gasoline equipment. However, the fuel tank volumet
   provided often did not  quire match die equipment categories used by EPA in this study and
   aggregation was requited  When poiaMe, a weighted average of pertinent fuel tank volumes
   wai used to generate an effective fuel tank volume for die particular equipment category and
   emission source.  If die data supplied by manufacturers marched on equipment category
   exactly, the data were used directly.
         Effective fuel tank volumes iuf not necessarily cons cant for refueling and evaporative
   emission factor calculation*.  Inrtead, an effective  fuel tank volume should be calculated for
   each emission and equipment type because refueling and evaporative emiiaicniB are functions
   of different factors. A particular weighing factor may be import ant when aggregating fuel
   tank volumes for diurnal emission factor calculations, but that same weighing factor may not
   be important when calculating refueling emissions, or vice-versa.  For example, walk behind
   lawnmowtrs have a range of fad tank volumes of 0.37 to 0.68 gallons.  It is known that the
   smaller fuel tank volumes lend ID be used by consumers while equipment with larger tonka
   tend to be used commercially. Furthermore, although there may be fewer commercial
   kwnmowen (large fuel tanks), their icaion length is probably longer. The effective fuel tank
   volume should account for population sues and length of seasons. Other weighing factors  are
   used when calculating  an effective fuel tank volume for refueling emission factors. Refueling
   emissions  an influenced by the amount of fuel consumed, which is a function of population,
   horsepower, load factor, bake specific fuel consump'ion and usage rate. The effective fuel

   tank volume for refueling emissions should account for these factors.  Therefore, the purpose
   for which the  overage fuel tank volume is calculated dictates how individual fuel tank
   volumes are weighted.
         The discussion below presents effective gasoline fuel tank volumes for evaporative and
   refueling emissions. Fuel tank aggregation for calculation of gasoline refueling emission
   factors are discussed first and fuel tank aggregation for calculation of gasoline evaporaiive
   emission factors are discussed afterwards, The aggregations were often reduced to mere
   population weighings or averages because so many weighing factors were not available (Le,,
   if a particular weighing factor is not known, then the category  \s assumed to be homogeneous
   with respect to that weighing factor).  For this reason, gasoline fuel tank volumes used for
   calculation of evaporative emissions, are.the same as diose used for refueling emission facton
   unless specifically indicated pff ^ifffTTrrt i" the section tided Manufacturer's Date for
   Calculation of Gasoline Evaporative Emission Factor*.  In  addition, several fuel tank volumes
   were taken directly from data supplied by manufacturers but those are not discussed below.
   Those data are readily identified in Table 1-15,

   For example, the fbel tank volume for Gtneraior Sets is also used for Signal Boards because
   signal boards use generator!.  If a substitution u not possible or justifiable, then the second
   alternative is to calculate fuel tank volumes based on regression analysis.  A regression of

   line arc diescl fueled.  There may be some concern ihal fuel tank volumes of similar ditsel
   and gasoline equipment do not approximate each other became a particular piece of gasoline
   equipment tends to be smaller and hove a smaller fuel tank than its diesel counterpart. This
   should not be the  case when comparing gasoline and diesel equipment of similar horsepower.
   When the influence of the size of engine is removed, as done by the regression, that
   difference should  be minimal.  On the contrary, a larger mass of gasoline ia required to do the
   same amount of woik as done by a dieael fueled piece of equipment (i.e., rhe brake specific
   fuel consumption  of gasoline equipment tends to be higher) and, therefore, gasoline fuel tanks
   would necessarily be larger to accommodate the same amount of work. Thus,  use of ihia
   regression may  slighdy overeatimaDe gasoline spillage emissions but underestimate gasoline
   diurnal emissions ,
          Due to the lad of data fan much of rhe equipment, the regression line was used

   3.3.    Methodology Used to Calculate Refueling Emission Factors

          HUB section will present the methodology and data used to calculate refueling
   emission factors for gasoline and dies el equipment. The reader is referred to section 3,1,
   Concepts of Refueling and Evaporative Emissions, for a definition of refueling emissions,
            ).l. Gasoline Refueling Emission Factors
          Spillage -- Veiy linie woit has been done to quantify the amount of fuel spilled while
   refueling noruoad engines. The only known spillage valuei have been presented by Briggs &.
   Sti-ition and OPEI for lawn and garden equipment (primarily standard walk behind
   lawnmowen),  Briggs & Stratum lias presented a value of 45 grama (approximately 1.5 oz.)
   per refueling and suggested that the value be reduced m 22.5 g/ft fueling as ihe user becomes
   familiar wiih ihe equlpincni.44  OPEI repotted in a study completed in September of 1991
   diet 17 puns of fuel wen spilled during a typical refueling incident.  All of these values arc
   much higher than the spillage valve *hich may be backed our of Mobile4 for cm-highway
   vehicles which is roagbly 3.6 g/refading (0,31 g/gftl x  11,5 gal/refuel),**
          The discrepancy between the Mobile4 valae and the OPEI and Biigga & Straiten value
   is most likely due to the fact thai (1) many nonroad engines ate refueled from fuel containers
   which are more difficult to use than gasoline pumps, {2} fuel containers do not have
   automatic shut off capability and (3) equipment fad tankfl are not as accessible. Therefore,
   the numbers provided by OPEI and Briggs & Straton are probably  closer to ihe true value for
   nonroad engines which ate typically uetueled from a portable, hand-held fuel container.
   When deriving the emisikm factors presented in this study, EPA haa assumed thai 17 g of
   fuel is spilled per refueling when a portable fuel container is used and, for nonroad equipment
   that is refueled from a gasoline pump, spillage ii assumed to be 3.6 g/irefucling. EPA chose
   the OPEI over tbe Briggs Sc Stimcton value because it is based on substantially more data.
          The method  of refueling (pump or container) is discerned by equipment Type  and fuel
   tank size. Lawn and garden (except chippera/snimp grinders), recreational, and light
   commercial equipment aie assumed to be refueled Cram portable fuel  containers,  In  addition,
   any other equipment with tod.  tank volumes les§ than 6 gallons40 ** are assumed to be

   dispensed from underground storage rants. It is unlikely that the temperature of fuel
   dispensed from a portable fuel container will  march that of fuel dispensed from an
   underground storage tank.  Rather, the fuel temperature from a portable container will most
   likely match thar of me fuel in ihe equipment since both the container and equipment are
   exposed to the same ambient conditions.  There fore, the "pump dispensed" values suggested
   by Roihrrum and Johnson are used only for equipment refueled from gasoline fuel pumps, For
   equipment refueled from fuel containers, the values Td arc assumed equal to the equipment
   tank temperature. Thiu, dT is zero.
         It can be correctly argued that the dispensed fuel temperatun for many nonaaainment
   areas will he dissimilar to ihose values presented above—especially the winter time values.
   While recognizing iMa deficiency, IP A is unable to incorporate eity-by-ciry  emission factors
   due to the immense size of that task. The best available national emission factors are used
   for all clues.  A list of equipment and the associated  displacement emission  factors as well m
   total refueling emission factors ia located in Table  US.
         To make the refueling emission factors compatible with the populations and usage
   races used in the study, die refueling emission factor  units were  changed from grams per
   gallon to grams per horsepower hour (except some recreational equipment which are
   expressed in g/nr and marine vessels which ore expressed in g/gal) by  multiplying the original
   value by  ihe brake specific fuel conaiunptton (BSFC).  To facilitate that change, assumptions
   regarding BSFC were neccuwy. BSFC data provided by SWRI and CARB were used to
   estimate BSFC's for equipment with avenge horsepower of S hp and less, 8 hp to 20 hp and
   above 20 hp.  The valuei ittumed are 0.219" tf, 0.15* M. or Q.QSM*  gal/hp-hr,

          Refueling emission factors for all recrvalional equipment except snowmobiles are
   expressed in units of g/hr, instead of g/hp-hf.  The conversions wire made by multiplying the
   original value in g/hp-hr by the average horsepower and load factor supplied by EEA,  For
   example, the conversion for minibikes ia:

          3.32. Diesel Efftuling Emission
          Refueling emissions from dieael rueled equipment are not aa significant as those from
   gasoline fueled equipment because dieael fuel has a relatively high initial boiling temperature
   of 350 °F which impedes its evaporation.  Gasoline, on the other hand, has initial boiling
   temperatures of 60 - SO oF depending on the season of y«ar (EVP) and, therefore, evaporaics
   more readily.52  Aa • result, very little weak has been done to quantify dlesel refueling
   emissions.  Indeed, EPA Is not aware of any studies of emissions  from spilled dksei fuel.
   However, work has been done by F_ Peter  Hutcfaina of the EPA to quantify displacement
   emissions from diescl fuej.5*  Hutchins' work has ihown the displecemtnt emissions from
   diesei fuel to be 0.041 grama per gallon of fuel dispensed and fuel tank lemperatQies of
   approximaicly 80 aP. For the purpoaea of die present study, all diesei «quipnent are
   assumed  to emit HC vapon at a rare  of 0,041 grams per gallon of fuel  dispensed.  EPA is not
   aware of any other data pertaining to refueling or evaporative emisiioni from dicsei fueled
   equipment and, therefore, other diesei refueling emission sources are rot included in this
   smdy.
          Just as wag needed for die gasoline refueling emission factors, the diesei refueling
   emission factors were adjusted ro be compatible with die populations and usage rates used in
   the study. The units were changed from grams per gallon to grama per horsepower hour

          some recreational equipment which aie expressed In g/hr and marine vessels which

   fuel consumption (BSFC) were necessaiy. Recognizing that dies*! equipment generally have
   lower BSFCs than gasoline equipment, the gasoline BSFC values were multiplied by 0.8 to
   esumate BSFCs for disacl equipment1*.  Therefore, the BSFCs assumed in ihis repon for
   diesel equipment are 0.175, 0,12, and Q.QC3 frt/hp-hr, for engines under 8 hp, between 8  and
   20 hp, and ovex 20 tip, respectively.  Refueling emission factors for all recreational equipment

Nonroad Eocmc and Vehicle Baiiaaoa Study
          Hot Soak — After reviewing SAE papers and SwRI reports regarding evaporative
   emissions and referring with several manufacturers, EPA found no appropriate values for hot
   soak emission factors for nonroad engines,  Hoi soak emission values for cm-highway engines
   do exist, but they are not representative of nomt)3d engines due to the different size, design,
   packaging and cartsuietors that each employs.  Therefore, diis study does not account for hot
   soak emissions.
          Renting Loss — Resting loss emissions are not included in this, study due to the I act
   of available data. However, to obtain zfai for the potential magnitude of this type of
   emission, one can consider ihe amount of fuel a plastic storage container is permitted to lose
   and still meet the standards  devised by the  American Society for Testing and Materials
   (ASTM).  A nonmetflllk fuel container passes the standards set by ASTM  if it loses less than
   1 %  of its mass over 30 days at a temperature of 75 OF,  Hie test fuel used IB a 70%
   boocrane, 30% toluene mixture (by volume). Assuming thai the test fuel and regular gasoline
   behave the same, the standard indicates the fuel container could lose up to  28  grams of fuel
   per month,
          Running Low — Just as for hot soak emissions, no data on the subject of running [095
   emissions for noiuraad engines was  found and on-highway  values would not be representative.
   Therefore, running  loss emissions an not accounted for in chis study.

          3.4,2,  DleaeJ Evaporative Emission Factor*
          EPA is not  aware of any dieaeJ evaporative emission data and therefore, dks«l
   evaporative emissions an not included in thia study.  On a qualitative basis, however, it can
   be said rhai evaporative emiuiona from dieseJ equipment should be much less than
   evaporative ernutioni from gasoline equipment because diesel fuel has a relatively high initial
   boiling tempi ramie of 350 °F which impedes its evaporation. Gasoline, on ihe other hind,
   has  initial boiling Bemperatare* of 60  - 80 °F depending on ihe season of year (RVF) and,
   therefore, evaporates more readily.5*

                          Chapter 4,  Crattkcas* Emission Factor*

         Crmkjciie emission factors an presented in this section for gasoline and diesel
   nonroad equipment after a brief introduction of erankcase emissions,
         Crankcasc emissions are those exhaust gases which, upon leaving die combustion
   chamber, do not pus through the exhaiiit valve.  Rattier, die gases discharge into the
   crankcase via the clearance between the piston and cylinder wall.  Eventually, these gases
   may escape from the crankcase to die atmosphere, hence, they are named crankcase emissions
   and die erankease is said to be  open.  Some manufacturer! produce engines which route
   crankcas* vapors to  (he air intake system of the equipment.  Those crankcases art called
   dosed crankcases,  Crankcasc emissions, together with evaporative, refueling, and tailpipe
   emissions, constitute die total emissions from an engine,
         Ail gasoline 4-suoke equipment are assumed to have open ctankcases except Lawn
   and Garden Equipment (but not Chippers/Stump Grinders—they are assumed 100% open),
   Vessels wfInboard Engines and Vessels w/Sterndrive Engines. Only 21% of Lawn and
   Garden Equipment are assumed open1* " and 100% of Vesxis wilnboard Engines and
          vftSterndrive Engines an assumed to have closed crankcases.
         The rest of this chapter  is separated into two sections. The fine section inuoduces
            «miaiiofi factors for 4-3trote gpotioe fueled engines and the second inuoduces
   crankcase emission factors for 4-smoke diesel fueled engines. Crankcaae emiasiom from 2-
   stroicc engines do not exist due to the natim of 2-stmlte engines.  Thus, for equipment with
   both 2-suoke and 4-stroke virietiM, die crankcase emiiiion factor is applied only to the 4-
   stpike engines when calculating total emissions.
          This section will present crankcase emission facton for nonroad gaaollrw engines and
   describe the methodology for developing them.  EPA ia not aware of any significant nonroad
   crank case emission data and has been forced to utilize  data from on-highway engines.  Even

   so, estimatti for ciankcase carton monoxide (CO) or oxides of nitrogen INQX) could not be
   found. Therefore, (hose pollutants  arc not considered for gasoline nonroad crankcase
   emissions.  The following paragraphs will present crankcase HC emission factor* for gasoline
   nonroad engines.
          Probably the most -widely accepted values for nonroad  crankcaac HC emissions are
   those found in AP-42.1*3  AP-42 reports crankcase HC eirussiona for Cum and construction
   equipment baaed on woik performed by Southwest Research institute (SwRJ)  in the early
   1970's.6' The SwRI wort on crankca« HC emissions suggests that "crankcase hydrocarbon
   emissions are equivalent  ro about 20 percent of those in the exhaust . , ,"**  This
   generalization is based on work performed by Charles M. Heinen*3 and P. A.  Bennett, et
   al** "** for on-highway vehicles. However, when calculating crankcase emissions, Hare
   and Springer misinterpreted the Henten report.  Heinen actually proposed the  value of 33% of
   exhaust emissions  (20% of total HC emissions) which was estimated by Fred W. Bowditch of
   General Motors.*1  Heinen chose Bowdich's number aa  the ben cornprorniae  of competing
   values supplied by CARB (31% of uncontrolled HC exhaust; 20% of total)*  the Fecferal
   Government (49% of uncontroUed HC exhouat; 26% of total/1 and Bowditch (sec chan
   below).  The origin* of tbe values supplied by the Federal Govemmenr and CARS are
   unknown while die crankcase emission values put forth by Bcrwditch (33%  of uiwonuolled
   HC exhaust emulsions and 20% of  total emis&ions) appear to be educated estimates based on
   General Motors "quality audit data".

         Alter updating AP-42 using Bowdirch's number, the values for crankcase emissions

   respectively. These corrected AP-42 estimates closely agiee with an EPA snidy of crankcase
   HC emissions from nine on-high way vehicles with disabled PCV systems and disconnected
   fresh air hosts on a gram/hour basis.6"  The EPA found thai the nine vehicles studied
   emitted, on average, 1.92 grams of HC per mile (376 g/hr baaed on 3 bag FTP with average
   speed of 19-6 mph) over the first three bags of the FTP driving schedule with PCV and freih
   air hose disconnected.  This value, 37,6 g/hi, compares  reasonably well with the updated AP-
   42 estimates of 42.24 and 47.2 g/hr for tractor and nomractor farm equipment, respectively,
   run over a steady state mode teat.  For purposes of estimating ratal emissions from 4-stroke
   gasoline nomoad engines, EPA accepts Bow ditch'3 value (33% of untreated exhaust) for all
   gasoline engines with open crankcases. Four-stroke engines wtrh closed crankcases  and all  2-
   stroke engines are assumed to have no ciankcase emissions.
         There may be concerns regarding the reliability of Bowditch's crankcase number (33%
   of uncontrolled HC exhaust) for use with today's nomoad engines,  Ite relationship between
   ort^highway crankcase emissions and nonfood crankcase emissions has never been
   documented for current year on-highway and nomoad engines,  Differences  in operating
   cycles,  machining tolerancea* fuel delivery systems,  etc., of on-highway and nonroad engines
   compromise the ability TO use existing on-highway engine exhaust and crankcase emissions to
   generate nonroad emission facton.  For instance, technological advances in combustion design
   for on-highway vehicles may not have been applied to nonroad engines to date.  In  addition,
   those advances may decrease exhaust and/or crankcase  emissions but perhaps
   disproportionally. Despite (he legitimate concerns mentioned above, EPA believes that the
   Bowdhch number remains the best available estimate for crankcase emissions because  it has
   been corroborated by EPA in Report #460/3-84-011,**  In addition, it is more conservative
   ihan Bennett's number which baa not been corroborated by other sources,

          This section will present the best available HC, CO, and NOX emission factor; for
   nonroad diescl engines and describe the methodology for developing them.
          Data for cnmkcase emissions from diesel engines is limited.  In fact, no studies which
   explicitly investigate crankcase emissions from nonroad diescl engines have been found.

FINAL - November 1991

However, studies have been found for on-highway crankcase emissions < The most recent and
comprehensive paper has been published by Charles T. Hate and Thomas M Baines,70  Hare
and Baines studied throe engines of which two were approximately half way becween
overhauls and che other was relatively new.  They found that hydrocarbon crankcase
emissions represent approximately 03 to 4.0 percent of corresponding exhaust hydrocarbon
emissions (0.006 to 0,017 g/kW-hr) when nested over die  13-mode test procedure.  These
values are consistent with earlier studies conducted by Chevalier71  (approximate average
value = 0.0395 gykW-hrttr> of heavily worn dkscl engines and Caterpillar (0.017 g/kW-
hr),n  The condition of the Caterpillar engine was not reported. For the purposes of EPA's
nonroad study, diesel crankcase  HC emissions will be assumed to  be 2 percent (the mean of
the range found by Hans and Baines) of untreated exhaust hydrocarbon emissions unless a
closed cronkcase is implemented.
      CO and NOx cmissiona from diesel crankcases have been reported by Hare and
Baines,  and Caterpillar  Hare and Bainea reported CO and NQx emission rales of 0.015 to
0.43 percent and 0.006 to 0.1  percent of exhau«t emissions, respectively. Their numbers are
corroboraifed by Caterpillar who reported CO and NOX emiasion rates of 0,23 and 0.076 of
exhaust  emission rates.  For the purposes of EFA's nonroad study, CO and NOX crankcase
emissions from diesel enginea will be assumed to be 0,2 percent and 0.05 percent (the mean
of the values repotted by Hare and Baines) of exhaust emissions, respectively. In cases
where the crankcase \a closed, EPA assumes zero diesel crankcase emissions.

         Bared on review of the limited available data for toxic emissions of benzene and 1,3-
   butaditne, EPA found it most appropriate in these coses to calculate emission rares as a
   weight percentage of die total hydrocarbon  emissions.  Benzene exhaust emissions arc
   expressed  ag roughly 3 percent by weight

          EPA has also chosen to express 1,3-butadiene emissions as a weight percent of tailpipe
           hydrocarbons plus ctankcase hydrocarbons.  The respective percentages vised in this
   study for nonroad diesel and gasoline engines are 1.6% and 1.3%-"  Emissions of 1,3-
   butadiene were almost never measured in engine exhaust prior to the laic 1980*5, because tlw
   procedures for doing so are relacively new.  Only one snidy was available wkh measurement
   fitiin diesel engines^ and one study with measurements from noncatalyut gasoline automobiles
   tested on unleaded gasoline. None of the studied found involved measurement from nonroad
   equipment and duty cycles.  However, due to the lack of additional infoimation,  EPA did
   apply these emission rates to all categories.

          In addition to HC, CO and NOg emissions, it has been documented thai nitrosamines,
   which have been found to be caicino genii: in animals, are emitted from vented diesel
   crankcases,™  While me contribution of motor vehicle emissions TO the niirosamine
   concentration is not known  for certain. Thomas M. Baines of EPA reports T7 that three
   researchers (Gordon,7* Shapley7* and Pellizzari") have identified nitrosamineg near
   roadways and rwo of the three suspected automobiles as a source.  Gordon reported
   nitrosamine concentrations as  high as 1.1  micrograma pet cubic meter in the Los Angeles
   basin.  In his technical report, Brines proposes 109 cancer incidents per year if 1.5 million
   people  are exposed to 1.1 micrograms per cubic meter for 2 hours per day.  Undoubtedly,
   crankca* emissions of nirrroamincs contribute to those  cancer incidents*".  The reader is
   referred to EPA's Integrated Risk Information System (IRIS) for a more  complete risk
   analysis and the technical report written by Thomas M,  Baines  for a more in depdi analysis of
   nitjosaminea from diesel erankcase emus ions and car interiors.

   Appendix K. Adjustments to Data in Developing Inventory A

         In developing Inventory A, EPA made several adjustments to annual hours of use,
   load factor, population data, and ihe emissions Inventory methodology for recreational marine
   equipment that BIC not reflected in the final reports from EPA contractors. These adjustments
   are detailed below,

   1.    Annual Hours of Use

         Annual hours of use data provided to  EPA from the P5R data base were largely based
   on the aasumption that ihe use of various equipment types k either consumer or commercial.
   In order to adjust for equipment types with a mixture of consumer and commercial use, EPA
   adjusted the data by multiplying the regional  hours of use reported  by ihe contractor by
   factors based on darn submitted to 1PA by QPH,* PPEMA,1 and GARB:1

   In the case of trtmmerVcdgers/brush cytters, it was necessary to also weight by population the
   annual hours of use for string and hedge trimmers,  for which PPEMA submitted separate
   estimates. Similarly, the value computed for leaf blowers/vacuums incorporates both

   2.   Load Factors
          Load factor data provided to EPA from ihe PSR daw base wen in some cases too high
   and in others too low. To correct ihe data, EPA substituted load factors determined by
   CARB for the entire lawn and gardcn equipment category,4 and data supplied by EMI for

3.   Pooutetfom-Chain Saws

       In constructing Inventory A, EPA relied on a methodology developed by PPEMA* for
allocating chain saw populations to the local level.  The methodology developed by EEA uses
single family housing units (SFHUs) and SIC 078 (landscaping and horticultural services i
employment. While this methodology is appropriate for most types of lawn and garden
equipment, chain Siwi are not generally used In major urbanized areas except by horticultural
services. One of the four models proposed by PPEMA is based on urban population [human 1
outside major urbanized areas, rural area population, and SIC 07S employment, which ia more
appropriate for allocating chain saw us*. The national chain saw population estimates
reported by EEA were disaggregated to the local level using the local allocations developed
with this methodology for Inventory BT as follows:
                                      Nn local
                         N.  locil =  —2	_ x N .  national
                                     NB national
where N refers to the number of chain saws (all sizes) and A and B refer to Inventories A
and B.

4.   Popttlations—Ajaicijltoral Equipment

       For Inventory A, regional agricultural equipment populations were determined by
multiplying FSR national population estimates by the ratio of local over national census data.
       Census data exists for some types of agricultural equipment at the local Level.
However, census counts do not differentiate between equipment that is inoperative or seldom
used and equipment used for agricultural activity.  National population estimates from the
PSR data baae are better estimates of equipment used regularly in agricultural activity than
the census count!,  However, the census counts are accurate indicators of local distribution of
the equipment. Thus, the census counts were used as indications to disaggregate the PSR
national population estimates to the  local kvel.

   6. Recreational Marine Equipment Emissions Inventory Methodology

          Population - Local boat registration dam were tued to establish the number of boats
   of each equipment type in each nonanainment area. However, two adjustments to this
   information were needed for inventory purposes. The first adjustment was to cum the number
   of boats into the number of engines. This was necessary to match in* horsepower and hours
   of use estimates, which were derived per engine. The methodology used to calculate the
   number of engines per boat for thii study was developed by EEA and provided to EPA.
          The second adjustment was to estimate the number of engines actually used in the
   nonaxtainmcnt areas. Unlike most of the equipment contained in this study recreational boats
   mt frequently transported long distances, such that when they are used may be different from
   where they are owned. Survey results submitted by NMMA for eight nonattainrnent areas         ^§
   were used as the basis for these adjustments. The survey was conducted for NMMA by Irwin
   Bit>h and Associates, Inc. (TB&A).7  Questionnaires were mailed at random to registered boat
   owners within and in counties lying within a 50-mile belt of the following nonattoJiuneni
   areas;
                      Baltimore. MD             Hartford. CT

                      Denver, CO                Seattle, WA
         The questionnaire asked a wide variety of questions about the kind of boat($) owned;
   engine number, type, and size; amount, location, and time of usage; and fuel  used. The

       where:
                 - engines used in nonattainment area
             ER = Engines registered in rKmartainment area
             Fuel used in n/a area - the sum of the repotted amount of fuel consumed
                    inside the nonanainment area by boats registered inside the
                    nonanainment area, plus the fuel consumed within the nonartainment
                    area by boats registered outside the nonattainment area
             Fuel used by boms registered in the n/a area ** The total reported amount of
                    fuel consumed by boats registered inside the nonanainment area without
                    regard to where the fuel was consumed,
             % use from 0-1 mile offshore =• The survey reported offshore use separately
                    from on-shore use.  While offshore emissions have variable effects on
                    nonattainment aiea air quality,  depending on meteorological conditions,
                    it would be inappropriate to totally ignore such emissions. Thus, beat
                    use within one mile offshore of nonattainment areas located on the
                    ocean or the Great Lakes was used as an approximation of the offshore
                    emission contribution.  This contributed a relatively small fraction to
                    total boat usage in mosr nonattainment areas.
       While the number of hours of use were also reported by the survey, Fuel use

chosen as a better representation of actual boat usage based upon NMMA's stated belief that
the reported fuel use was likely to be more accurate than the reported hours (NMMA was

concerned that the reported hours were the number of hours the boat was in the water, not the

number of hours the engine was being operated).
       For the eight areas surveyed by IB&A. the actual survey results for each area were

used to calculate individual ratios of engines used to engines registered, For the other 16

areas, the average ratios from the eight surveyed areas were used.  For all areas, separate

ratios were calculated for the five different equipment types in the recreational marine

category.
-------
    Engine tod Vehkte Emiarian Stmiy
       Because 16 of the areas were not surveyed, the average ratios determined from the
eight surveyed areas exceed reasonable maximum boat use in nonartainment areas  with
relatively little water surface area. To account for this, a, calculation of the maximum number
of boars that could be operated normally on the available water surface area was made for
each ttonanainrnent «ta according to the following formula:
                 max boats =  Walct 3>urfa|CC areft fa nonattiumnmt area
                                         Area required/boat
       The- waier surface area in each nonattainment ana was supplied by EEA.  The area
required/boat was supplied by NMMA based on saturation limits determined for a joint study
by EPA and marine engine manufacturers in the early  1970's (Grant No, R-801799), plus the
IB&A survey reeulti for types of boating activity,
       NMMA supplied information suggesting ihat die available hours of prime boating use
are 384 houra/ycar  (12 weekVyear, 4 days per week, 3 hours/day).  This figure was multiplied
by the maximum number of boats to yield the maximum number of summer boat hours that
could be supported within each nonartainmem area without hindering boot activity.
       This theoretical maximum number of summer boat hours inside the nonanainment area
was compared to the amount of summer boat hours inaide the nonartairunent area calculated
from the survey results and the local boat registrations. The calculation of summer boat
hours from the survey and registration was made using the following formula:
  Summer boon

       where:

             # n/a boats = ft boon mfiifcied in the nonanainment area
             hours = total annual houra of use per boat from the survey for boats registered
                    in the nonartainmeni area (includes hours operated outside the
                    nonattaiitment area)

                Fuel used ... = Both tenru have the same meaning as defined, above. In the
                       formula calculating engines used in normltainment area*
                Summer usage = Jteponed proportion of summertime operation from the survey,

          In cases where the calculated summer boat hours exceeded the theoretical maximum,
   the calculated number of engines used in the nonartairtrnent area was reduced by the ratio of
   the theoretical maximum summer boai hours to the calculated summer boat hours. Because
   chis correction ratio docs not include offshore  boar use, the average offshoie use was
   subtracted prior to applying ihe correction ratio. For areas on the ocean or on a Great Lake,
   ihe average of the offshore uaagc proportion for ihe five areas with offshore use wan added
   back after applying die collection ratio.

          Annual Fuel  Ute Estimates - The load factor, horsepower, and regional hours of use
   supplied by PSR were multiplied by ihe following BSFC estimates determined from test  data
   supplied by NMMA for recreational marine engines (the BSFC  calculations are discussed in

         Annual houo of use data provided to EPA from the PSR data base re flea different

   several adjustments to this data,
         Ai ozone cxoeeduices are typically a summertime problem and CO exceedinces a
   wintertime problem, EPA developed seasonal adjustment factors to reflect the use of
   equipment depending on the season of the year
         This appendix describes the assumptions made by EPA in calculating regional hours of
   use and summertime and wintertime emissions.

   1.   Regional Adjustments

         EPA has allocated the nananainrncnt areaa studied to eight regions. Table L4J1
   indicates the nonattainment areas thai fall into these eight regions, as well as the seasonal
   designations for each region.
         In constructing Inventory A, EPA used  annual hours of use data for each region as
   supplied from the PSR data hue, aa indicated in die EEA final nrpon, except for the
   following:

          Hare and Springer also reported apiculturHl seasons of ISO, 225, and 270 days for the
   northern, central, mid southern regions, respectively.  This  corresponds to summer activity
   percentages of 50%, 40%, and 34% in the same regions. The 1987 SIP emission inventories
   for both Boston and Atlanta reported that 90% of agricultural equipment activity occurs
   between April and October, yielding a wintertime activity percentage of 6% in both arc is.
   Thii figure was herein applied to a]l nonattainmeiK areas to estimate wintenime agricultural
   equipment activity.
          Because of similarities in the growing seasons, summertime activity percentages for
   lawn and garden equipment (excluding chain saws and snowblowers) were estimated to be the
   same as those for agricultural equipment,  CARD estimated in the Technical Suppon
   Document for its proposed regulations applicable to lawn and garden equipment tJiat
   wimenime  activity accouitied foi about 6% of yearly activity. Thia figure was  applied to the
   southern region,  and the wintertime activity percentages in the central and northern regions
   were estimated to be 3% and 0%.  However, it was assumed that all 5 now blower activity
   occurs  during die winter.
          The industrial equipment seasonal activity percentages listed above are based on
   seasonal adjustments used in several 1987 SIP emission inventories. Of those considered in
   this studied, only dial for Chicago reported any noniuiifbrmity of industrial equipment
   activity - the summer ponton of yearly activity was reported to be 30*. Thia figure was
   applied to the northern re pan, and the wimciume activity  percentage was consequently
   estimated to be 20%, Activity in the central and southern regions was estimated to be
   uniformly distributed across the  year.
          Due to the year-found natal* of equipment use, no seasonal adjustments were mack to
   activity for commercial marine vessels, airport service vehicles, logging equipment (including
   all chain saws), or light commercial equipment.  The survey  conducted by NMMA of
   re ere at ion boss, owners included  information on seasonal boat usage.  These results were  used
   to establish seasonal adjustments for each of die eight regions used for regional hours of use
   adjustment  as shown in Table 1X13.

Appendix N.  EPA Use of Manufacturer Data In Inventory B

       In developing activity levels for Inventoiy B, EPA used data supplied by
manufacturers or manufacturer associations where it was available.  In some cases, EPA had
to adjust data for use in the inventory.
       The kinds of data supplied and the adjustments to the data are detailed below.  Part  1
is a general overview of the data supplied by manufacturers and used by EPA in constructing
Inventory B.  Part 2 contains more detailed adjustments made to the data for use in the
inventory.

1.   General Overview

       1.1. Equipment Manufacturers  Institute (EMI)

       EMI provided population data for several types of agricultural and construction
equipment. These equipment types are listed in Table N-01.  Estimates of average engine-
rated horsepower, annual use, and load factors  were also available for these equipment rypes.
       EMI estimates for crawler loaders were considered together with crawler tractors as
fitting within the Inventory A estimate  for crawler tractors.  Because cotton pickers were
included in Inventoiy A under "other agricultural equipment," EMTs cotton picker estimates
were only considered in areas where the populations were higher than the Inventory A
estimate for other agricultural equipment.
       There were several equipment types for which population estimates were not provided
by EMI, but for which EPA incorporated horsepower, annual use, and load factor estimates
from EMI in developing  Inventoiy B.  These included swathers ("windrowers"), mobile
elevating work platforms ("aerial lifts"), landfill compactors ("crushing/processing
equipment"), and square balers  and bale wagons ("balers").  Because of either negligible
equipment populations or the absence of any matching equipment type, data for the following
equipment types was not considered: leaf loaders, milling machines, horizontal earth borers.
forage harvester!, augers, and cranes.
       Additional adjustments to EMI  data are detailed below in Part 2.

         1.2.  Outdoor Power Equipment Institute, Inc. (OPEI)

         OPEI provided data on nonhandheld equipment types shown below in Table N-02.
   EPA combined OPEI's separate estimates for lawn tractors and garden tractors to replace the
   data for lawn and garden tractors from Inventory A.
         OPEI supplied test data which were used to calculate load factors for lawnmowers,
   rear engine riding mowers, front mowers, and lawn and garden tractors.  For other equipment
   types, EPA used the CARB load factors in Inventory B.
         Because OPEI reported separate annual hours of use estimates for commercial and
   consumer use, EPA used OPEI's reported percentages of such use to construct weighted

          1.4.  Industrial Truck Association (ITA)

          ITA provided load factor, annual hours of use, and CMSA-level population estimates
   for industrial foridifts, which were used in Inventory B as provided.

          1,5.  International Snowmobile Industry Association (ISIA)

          ISIA provided national population and annual hours of use estimates for snowmobiles.
   To obtain CMSA-level populations, EPA multiplied CMSA-level populations from Inventory
   A by the ratio of ISIA national populations to Inventory A national populations,

          1.6.  National Marine Manufacturers Association (NMMA)

          Population Data — Local boat registrations were used to establish the number of
   boats of each equipment type owned in each nonaitainment area, as was done for
   Inventory A.  The same method was also used to calculate the number of engines from the
   number of boats.  However, NMMA requested that the adjustment for the number of engines
   actually used in the nonattainment areas be handled differently than was done for
   Inventory A,  Rather than directly rely on the ratio of the reported fuel consumed in the
   nonattainment areas to the reported fuel used by boats registered in the nonattainment area
   from the  EB&A survey, NMMA requested that the adjustment be handled by a formula based
   upon the  water surface area per registered boat in the nonattainment area.
          The formula was derived from the relationship between water surface area per
   registered boat and the reported ratio of fuel consumed in the nonattainment areas to the fuel
   consumed by boats registered in the nonattainment area for the eight surveyed areas.
   Equations of the form Y = 1 - exp (kx»"^» provided the best fit to the data, where
          Y =   ratio of fuel used in the nonattainment area (from boats registered both inside
                and outside the nonattainment area) to total fuel used by boats registered in
                nonattainment area (includes fuel used outside the nonattainment area)
          X =   local water surface area/registered boat in nonattainment area
          k and m are coefficients

          The value of m was used to calibrate the formula such that the highest r2 values were
   obtained without yielding larger values for y in any nonartainment area than the ratio of the
   theoretical maximum number of summer boat hours inside a nonattainment area to the total
   summer hours of use calculated for boats registered in a nonattainment area.  This ratio was
   calculated as follows:
                             [water surface area in n/a area] ,„*,,,
                              	 (384)

                                                fuel used by boats registered in n/a area
          The definition of the above terms and the derivation of this formula are discussed in
   Appendix K, Section 6.
          The value of k was determined by the regression. The final formula developed was:

                                      Y  = 1  - expE23>*>"M

          This formula was used to develop the basic ratio of fuel used in the nonartainment
   area to total fuel used by boats registered in the nonattainment area for each of the 24 areas.
   For those areas located on the ocean or  the Great Lakes, the proportion of use within 1  mile
   offshore reported by the survey for the five areas on the ocean or a Great Lake were added to
   the basic ratio. The final ratio was multiplied by the number of engines registered in the
   nonattainment area to calculate the number of engines used in the nonattainment area.

          Fuel Use — For the eight surveyed areas, the average fuel use per engine reported in
   the survey for boats  registered in the nonartainment area were used in the inventory
   calculations.  For the nonsurveyed areas, NMMA submitted  a national average fuel use
   estimate for outboard motors of 91 gallons/year. This estimate was based on the amount of
   2-stroke marine motor oil consumed each year. The average fuel use reported in the survey
   for outboard motors  was 142 gallons/year.  NMMA requested that EPA use the
   91 gallons/year estimate for outboard motors for all of the unsurveyed areas, and scale the

   average fuel me reported by the survey for the other equipment types by the outboard motor
   factor, i.e., 91/142.

          Seasonal Adjustment Factors — As was done for Inventory A, the proportion of boat
   use in the summer and the winter was based on monthly usage reported by the survey
   respondents.

          1.7. Motorcycle Industry Council, Inc. (MIC)

          MIC provided EPA with survey information on the number of miles ridden annually
   by ATVs and off-highway motorcycles." An average speed of 25 miles per hour was
   assumed in order to  convert these figures into hours per year.  MIC also provided national
   population figures, which were distributed to the local level using the ratio of the local to
   national population estimate for Inventory A.  The same distribution between 2-stroke and 4-
   stroke versions as reported by EEA was used in developing Inventory  B.

   2.    Detailed Adjustments

          2.1. Equipment Manufacturers Institute (EMI)

          EMX supplied load factor, horsepower, annual hours of use, national and CMSA-level
   population data for various types of construction equipment.  The data supplied and the
   adjustments made to the data are detailed below.

   Equipment Tvps            EMI Data and Adjustment
   Crawler Tractor            EMI supplied national horsepower and load factor, as well as
                              national and CMSA level populations and hours/year separately
                              for crawler loaders  and tractors.  National hours/year were
                              estimated by population weighting the regional values supplied
                              by EMI over all 24 areas. To estimate aggregated hours/year for
                              all crawler loaders and tractors at the regional level, EPA
                              population weighted the regional values for both equipment

types.  To estimate aggregated horsepower and load factor at the
national level, EPA weighted data for both types by (population)
(hours/year) and (population) (hours/year) (horsepower),
respectively.

For wheel loaders EMI supplied national population, horsepower,
and load factor, as well as CMSA level populations and
hours/year.  EPA estimated national hours of use by population
weighting regional values over 23 nonattainment areas.

For scrapers, EMI supplied data as for rubber tired loaders.

For motor graders, EMI supplied data as for rubber tired loaders.

For dumpers (off-road haulers), EMI supplied data as  for rubber
tired loaders.

EMI supplied national horsepower and load  factor, as well as
CMSA level populations and hours/year separately for crawler
and wheel excavators. EMI also supplied national populations
for all excavators - EPA  assumed a uniform national distribution
of crawler and wheel versions.  National hours/year were
estimated by population weighting the regional values supplied
by EMI over all 24 areas. To estimate aggregated hours/year for
all excavators at the  regional level, EPA population weighted the
regional values for both types of excavators. To estimate
aggregated horsepower and load factor at the national level, EPA
weighted crawler and wheel data by (population) (hours/year)
and (population) (hours/year) (horsepower),  respectively.

EMI supplied data for backhoe loaders as for rubber tired
loaders.

EMI supplied data for skid steer loaders as for rubber tired
loaders.

EMI supplied data for log skidders as for rubber tired loaders,
except that national populations were not provided.

EMI supplied data for rollers and compactors as for rubber tired

EMI supplied only a national population estimate for cranes.

EMI supplied only estimates of the national population, average
rated horsepower, and load factor for trenchers.

EMI supplied data for rough terrain forklifts as for trenchers.

EMI supplied data for cotton pickers as for rubber tired loaders.
EMI supplied local population and annual use estimates for
square balers and bale wagons, as well as national data for
horsepower and load factor.  To estimate national hours per year
for both versions individually, EPA weighted regional values
over all 24 areas.  EPA estimated aggregated hours per year for
all balers at the regional level by population weighting regional
values.  At the national level, EPA estimated aggregated hours
per year, horsepower, and load factor by weighting regional
values by population, (population) (hours/year) and (population)
(hours/year) (horsepower), respectively.

EMI supplied only horsepower and load factor data for mobile
work platforms.
         In the draft version of this study, data submitted by EMI for combines and agricultural

   tractors was used to construct Inventory B.  This included population figures developed by the

   U.S. Bureau of the Census, which EMI has stated may include seldom-used equipment.

   However, EMI has cautioned that, in constructing an emission inventory, appropriate

   corrections  should be made to either the operative population estimate or the estimate of

   average annual usage. EMTs submitted data contained no such correction. Consequently, the

   final version of Inventory B uses the same data as Inventory A for these two types of
   equipment.

          Population Data —  CMSA population data for lawnmowers, riding mowers, lawn
   tractors, garden tractors and tillers were supplied by OPEI*. However, because these
   categories do not fully match those equipment types used in the nonroad study, some
   aggregation and disaggregation was necessary. Lawn tractors and garden tractors were
   combined to obtain a value for "Lawn and Garden Tractors".  The tiller population was
   disaggregated into "Tillers < 5  hp" and "Tillers > 5 hp" and the riding mower population was
   disaggregated into "Front Mowers" and "Rear Engine Riding Mowers". In addition, all
   equipment populations were disaggregated into 2- and 4-stroke diesel and gasoline equipment
   types per EEA's methodology for each CMSA* as shown below.

   Tillers < 5 hp and Tillers > 5 hp

   Hours of use for lawn tractors and garden tractors were population weighted based on OPEI
   CMSA populations to get annual hours of use for "Lawn and Garden Tractors" for each
   CMS A, For example, the Baltimore CMSA 4-stroke diesel lawn and garden tractor annual
   usage number is:
                           40,000 lawn tractors x 41 hrs

   Tillers < 5 hp and Tillers > 5 hp
   Hours of use for tillers were weighted by commercial and consumer populations provided by
   OPEI in the addendum to their report. OPEI suggested that 18% of all tillers are used
   commercially and that 82% are used by consumers.  Commercially used tillers are assumed to
   operate 4 times as much as consumer tillers. Thus, the local consumer hours of use reported
   by OPEI for each area was multiplied by 1.54 to obtain overall hours of use, as follows:
                  0.82  x  (# consumer hours)

               (.82 + (.18 x 4) (f consumer hours)
   Tillers above and below 5 hp were assumed to have the same usage characteristics.

   Front Mowers and Rear Engine Riding Mowers
   Hours of use for "Front Mowers" and "Rear Engine Riding Mowers" were assumed equal to
   the riding mower value supplied by OPEI for each CMSA.  This assumption will probably
   underestimate the annual hours of use for "Front Mowers" because they are used
   commercially while "Rear Engine Riding Mowers" are not.

   Lawnmowers
   Hours of use for lawnmowers are also weighted by commercial and consumer populations as
   well as 2-stroke and 4-stroke populations. Based upon sales, useful life, and usage
   information supplied by OPEI, 94.8% of all lawnmowers are consumer and 5.3% are

          Load Factor Data - In a letter to EPA dated September 9, 1991, OPEI discussed the

   gasoline  'Trimmers/Edgers/Brush Cutters""", "Leaf Blowers/Vacuums", "Chain Saws
   < 4 hp",  and "Chain Saws > 4 hp". In an earlier version of this report, Heiden proposed a
   methodology that relied on urban single family housing units (SFHUs), rural SFHUs, and
   SIC 078  (landscaping and horticulture services) employment. However, because the
   regression coefficient for urban SFHUs was  negative in the case of chain saws and blowers,
   Heiden developed on additional model that relies on urban population [human] outside major
   urbanized areas, rural population, and SIC 078 employment.  For these two types of
   equipment, this additional methodology was used to construct Inventory B. For trimmers, the
   original methodology proposed by Heiden was used, as no other model was clearly superior
   on either an econometric or intuitive basis.
          The PPEMA chain saw population was distributed to over and under 4 hp ranges
   based on the distribution reported by EEA.

Nooroad Engioe and Vehicle Emission Study
   Horsepower
   Snowblowers
   Based on industry suggestions, different horsepowers for 2- and 4-cycle engines are used.

   4-Cycle Engines:
   GARB reports average horsepowers for consumer and commercial snowtnrowers.  Those
   horsepowers have been population and usage rate weighted to find the average 4-cycle
   horsepower for snowblowers":
                           Cons;    .90 x 10 krs x 4.5 HP
                         Comm:  •*- .10 x 60 hrs x 6.0 HP
                                    (.90 x  10)  + (.10 x 60)
= 5.1 HP
   2-Cycle Engines:
   The average 2-cycle horsepower for snowblowers was provided by LAWN-BOY*
                               Tteumseh Eng:     .15  x  3,0 HP
                               Sitmld Eng   ;   + .10  x  4.5 HP
                                                       3.75 HP
      tt Note: The CARS data does contain 3% 2-cycle engines. Therefore, the weighing is slightly understated.

   Appendix O.  Emission Inventory B

          Inventory B is presented in two sets of tables which summarize emissions from
   nonroad engines and vehicles, highway vehicles, and other area and point sources of
   emissions.  Each set  of tables summarizes emissions in each of the 24 nonattainment areas
   included in this study, as well as national emissions.
          In the first set of summary tables, nonroad emissions are calculated using new engine
   emission factors.  In  the second set of summary tables, nonroad emissions are calculated
   using in-use emission factors.

Nomoad Engine and Vehicle Emission Study
          To determine the ozonc-fonning potential of the emission inventory under "real-world"
   conditions, the model incorporated meteorological data from actual historical ozone episodes,
   Two recent serious multi-day ozone episodes were chosen for the model based on the
   presence of "typical" ozone-generating characteristics.  Most of the ROMNET results are
   based on a model of the meteorological conditions during the severe ozone episode of
   July 4-18, 1988.
          In evaluating the impact of various control strategies on reducing ozone in the
   Northeast Corridor,  including the strategy of reducing transported emission, the baseline 1985
   emission inventories were projected to the year 2005. The emission from the different source
   categories were assumed to increase according to predicted growth in highly correlated
   indicators such as population or employment in the relevant industrial sector. In applying
   emission control technologies to the source categories, it  was generally assumed that the
   controls could be completely in place and generating 100% of their theoretical effectiveness
   by 2005, assumptions which are probably quite optimistic.  One of the scenarios modeled
   assessed the impact of relaxing these assumptions.
          Three control scenarios were used to assess the impact of transport on the
   nonartainment areas in the Northeast Corridor. One applied maximum control technology for '
   NOX and VOC to the 2005 inventories over the entire ROMNET area.  Another applied the
   controls only to sources within the Corridor itself. The third scenario applied maximum
   control technologies only to sources that were outside the Corridor, yet were inside the U.S.
   portion of the ROMNET region. As an example of how these scenarios compare to the
   version modeled in the Clean Air Act, the maximum control technology was assumed to
   reduce, on average, overall VOC emission by 63% and NOX emission by 57% from the 2005
   baseline level. The CAA version would reduce VOC emission by  32% and NOX emissions
   by 32% over the same region. In one scenario where controls were applied only outside the
   Corridor, a packet of air was tracked from an origin in West Virginia up through the
   Massachusetts coast.  Ozone and ozone precursor levels along its route were modeled and
   compared to baseline (pre-control) levels. This comparison can be used to  suggest the
   distance over which transported pollutants can be expected to have a measurable impact on
   ozone levels. The path of the air packet and the difference in pollutant levels between the
   scenarios along that path are shown in Charts P-02 and P-03.  As can be seen from these

_                                                                       FINAL - November 1991
-------
                                                                  Transport and Noturoad Emissions
   figures, the effect of reducing ozone precursors outside the Northeast Corridor was still
   noticeable two days after the air packet had passed into the highly polluted Corridor. By the
   time the air packet reached central Connecticut, it had traveled approximately 340 miles from
   its point of entry into the Corridor, and yet the reduction in non-Corridor emissions still
   reduced the predicted ozone level in Connecticut by approximately 5 ppb.
          Another assessment of upwind controls on specific nonattainment areas can be made
   by comparing the ozone levels predicted in the Corridor nonattainment areas under the
   different scenarios.  The effect on these cities of reducing emissions from upwind sources is
   shown in Tables P-01 and  P-02.  Table P-01 shows the impact of reducing only non-Corridor
   emissions on ozone concentrations in Corridor cities.  Table P-02 shows the difference  in
   predicted ozone levels for  several cities between the scenarios with controls only in the
   Corridor and controls over the entire ROMNET region. Not surprisingly, the effect is most
   pronounced for those Corridor cities closest to the Corridor boundary, such as the
   Washington/Baltimore area and Philadelphia,
          The results show that a reduction of 65% of the non-Corridor VOC inventory and 60%
   of the non-Corridor NOX inventory resulted in an average peak ozone reduction of 8.6  ppb in
   the Corridor as a whole and 11.5 ppb average peak ozone reduction in the two western-most
   nonattainment  areas of  Washington/Baltimore and Philadelphia.  Very roughly, this implies
   that 1% of the non-Corridor VOC and NOX inventories account for 0.14 ppb of the peak
   ozone concentration in  the Corridor cities  on average and about 0,18 ppb  of the peak ozone
   concentration in the Washington/Baltimore and Philadelphia areas.
          While the reductions in ozone levels due to reduction in transported non-Corridor
   emissions may not appear  large, they should be compared to the reductions predicted for
   other programs.  For example, the ROMNET study also assessed the impact of a control
   strategy that would convert die entire motor vehicle fleet in the Northeast Corridor to
   methanol (methanol vehicles have less photochemically reactive  emissions) and also reduce
   the reactivity of solvent emissions throughout the Corridor. Average reductions in ozone
   levels for the Northeast Corridor cities were approximately 5-8 ppb under this reactivity-based
   control scenario.  These reductions are similar to the reductions predicted for reducing
   non-Corridor  emissions using maximum control technology for VOC and NOX. Neither
   measure alone could reduce emissions enough to bring the Corridor into attainment.

         According to the ROMNET report, "The results suggest that without stringent upwind
   controls, ozone levels in parts of the Corridor may not be reduced to below the level specified
   in the NAAQS even with stringent controls along the entire length of the Corridor."  (ES-ll)
   Attainment of the ozone standard across the entire region may require not only maximum
   control technology across the entire region, but additional substantial across-the-board
   reductions in VOC emissions in New York City.  Again, we should note that the maximum
   control technologies modeled here were assumed to achieve roughly twice the reduction in
   VOC and NOX emissions that are predicted to result from implementation of the minimum
   requirements of the Clean Air Act. The report goes on to warn: "Considering rule
   effectiveness and a  more realistic representation of control programs, results show predicted
   episode maximum ozone levels of just above 125 ppb in most sections of the Northeast
   Corridor with the most stringent VOC/NQj/reactrvity strategy simulated." (ES-ll)

          1.2.  Transport in California

         Section 3%10(b) of the California Clean Air Act required the CARB to assess the
   relative contribution of upwind emissions to downwind ozone levels.  In June 1990, the Board
   issued a staff report "Assessment and Mitigation of the Impacts of Transported Pollutants on
   Ozone Concentrations within California," which assessed the impact of transport for 14
   upwind-downwind area pairs.
         The California report differs from the ROMNET report in several aspects. For ten of
   the upwind-downwind area pairs, transport was not assessed using a complete regional air
   quality model. In these cases, the CARB staff analyzed emission inventories for the upwind
   and downwind areas, wind patterns that prevailed during nonattainment episodes, the timing
   of downwind ozone peaks relative to peak precursor-generating periods upwind (e.g., morning
   and afternoon rush  hours), and other available information to determine whether the
   nonattainment was  due primarily to upwind or downwind emissions.
          Obviously, this method does not allow for quantitative precision about the impact of
   upwind emissions on downwind ozone levels. The staff therefore limited its conclusions to
   categorizing the impact of transport on the downwind area in each transport pair as either
   overwhelming, significant,  or inconsequential.  "Overwhelming"  impact is defined in the

FINAL - November 1991
-------
Nonroad Engine and Vehicle Emiasioa Study
   CAJRB report as situations in which "ozone exceedances in the downwind area (other than
   very near the boundary between upwind and downwind areas) occurred without any emission
   contribution or with only a very small emission contribution from the downwind area." (1.2)
   "Significant" transport impact was found in cases where "emissions from both the upwind and
   downwind areas contributed to exceedances of the state standard,"  (1.2) and "inconsequential"
   impact was found in areas for which "the staff determined that upwind emissions did not
   contribute significantly to exceedances of the state ozone standard  in the downwind area."(1.2)
   Some upwind-downwind pairs fell in more than one category; that is, the importance of
   transport varied substantially depending  on meteorology so that transport might be judged
   substantial under some conditions and inconsequential under others.
          The CARB results are shown in Table P-03.  For all the transport pairs studied,
   transport was an "overwhelming" or "significant" contributor under at least some of the
   meteorological conditions that typically prevailed during ozone exceedances. Transported
   ozone and ozone precursors have an "overwhelming" impact on nonattainment in five
   California nonattainment areas under some conditions and a "significant" effect in ten
   nonattainment  areas  under some conditions.  Some of these areas fall into both the
   "overwhelming" and "significant" categories due to varying meteorological patterns among
   ozone exceedance episodes. Most upwind sources of transported pollutants are urban areas,
   but rural areas also may contribute to downwind nonattainment.
          The proportion of VOC and NOX inventories from nonroad sources in six upwind
   areas are shown in Tables  P-04 - P-Q9.  These tables show what is contributed from each of 5
   nonroad categories,  as well as the total nonroad contribution and total contribution from all
   area and point sources.  From this, an indication of the proportion  of transported pollutants
   from nonroad sources  which impact the  downwind area can be drawn.

          The Sacramento Valley Air Basin is an ozone nonattainment area.  Under some
          conditions, emissions from the Sacramento Valley significantly contribute to
          ozone levels in the San Joaquin Valley and San Francisco Bay nonattainment
          areas. Under some conditions, these areas significantly contribute to ozone

          1.3.  Transport in the Lake Michigan Areas

          Another area in which transport is believed to have a significant impact on ozone
   nonattainment is Muskegon, Michigan. Muskegon is a city of 160,000 on the eastern shore of
   Lake Michigan, approximately 185 km (115 mi) northeast of Chicago.  Its persistent
   nonattainment problems appear to be largely due to emissions from the Chicago area.  In July
   1988, during a high ozone episode for Muskegon, an instrumented research vessel recorded
   ozone levels and wind patterns over Lake Michigan to determine if the high ozone levels
   were being transported over the lake.  High ozone levels were observed over the lake and
   along the shore south of Muskegon.  Back trajectories of the air parcels containing the ozone
   levels showed that these air parcels originated along the heavily industrialized urban southern
   shore of Lake Michigan.  Further evidence of the importance of transport in causing this
   exceedance is die fact that Grand Rapids, a much larger and more heavily industrialized city
   than Muskegon approximately 50 km east of Muskegon, approached, but did not exceed, the
   NAAQS for ozone, although meteorological data were favorable for ozone formation in both
   Muskegon and Grand Rapids.  Back trajectories of the air parcels entering Grand Rapids on
   this day indicated that they passed  over the southern shore of Lake Michigan outside of the
   urban, industrialized Chicago/Gary area.
          EPA's Region V currently is coordinating the development of an Urban Airshed
   Model that will encompass the greater Lake Michigan area.  The Lake Michigan Oxidant
   Study (LMOS) will assess the transport of ozone precursor emissions and ozone across the
   lake to better explain the effect of emissions from eastern Wisconsin and the Chicago/Gary
   area on ozone levels in Michigan.  The study will include many new inventories to be
   developed by EPA and the states bordering Lake Michigan. The  Lake Michigan Oxidant
   Study will be completed in 1993.

   2.   The Effect of Transported Nonroad Emissions

          The fact that ozone is a regional and not a local problem has been demonstrated by
   studies described previously and is widely understood and accepted.  Congress demonstrated
   their understanding and acceptance of this concept by mandating the creation of regional

__                                                                       FINAL - November

   transport commissions in the CAAA. Transport work now concentrates on assessing the
   factors impacting transport and developing a way to model and quantify the transport effect.
          For the purposes of this study, EPA has used information gathered in developing
   ROMNET to tentatively quantify the effect of transported nonroad emissions on air quality in
   the Northeast Corridor.  The impact of nonroad non-Corridor emissions may be roughly
   assessed by looking at the proportion of the non-Corridor inventory generated by the nonroad
   source categories.  These categories are: nonroad diesel, nonroad gasoline, military aviation,
   civilian (commercial) aviation, general avktion, gasoline vessels, diesel vessels, and
   residual-fuel vessels. Their proportions of the inventory are shown in Table P-10.

          Several caveats should be observed in interpreting these numbers. First, the inventory
   proportions quoted in Table P-03 are for the base year 1985, not 2005, the year for which the
   control scenarios were modeled. Inventories for 2005 were not available from the ROMNET
   calculations because of the way in which inventory numbers were aggregated, speciated, and
   adjusted by the model during its projections.  Also, the myriad meteorological  and
   photochemical assumptions built into the ozone level predictions quoted in the last chapter
   make quantitative generalizations about the effects of changes  in transport on ozone levels
   somewhat hazardous.  Nonetheless, these calculations can help to illustrate the relative
FINAL - November 1991
-------

   magnitude of the effect of transported pollutants from nonroad sources on several important
   nonattainment areas.  Taken together, the categories of nonroad engines within the scope of
   this report accounted for 2.3% of the non-Corridor VOC inventory and 4.4% of the
   non-Corridor NOX inventory in 1985.  Given the correlation of non-Corridor inventory
   reductions and Corridor peak ozone reductions posited above,* it appears that transported
   pollutants from nonroad sources account for roughly 0.5 ppb of the peak ozone concentrations
   in the Corridor cities as a whole  and 0.6 ppb of the peak ozone concentration in the
   Baltimore/Washington and Philadelphia areas.  One context for assessing the importance of
   these impacts on urban ozone would be to compare the magnitude of the effect of transported
   nonroad sources to the levels of ozone predicted in the major northeastern cities after the
   implementation of the Clean Air Act mandates modeled  by R.OMNTET. As shown in
   Table P-ll, transported pollutants from non-Corridor nonroad sources would account for
   roughly 0.3-0.45% of die ozone level along die East Coast during ozone nonattainment
   episodes.

   3.   Transport Conclusions

          An analysis of ROMNET study finds the following:

   I,     Transport from all sources from non-Corridor areas into the Northeast Corridor
          contributes to nonattainment in several cities in the Northeast.

   2.     Currently, nonroad emissions outside the Corridor area account for approximately
          2.3% of the VOC non-Corridor inventory and 4,4% of the NOX non-Corridor inventory
          (see Table P-10).

   3.      In the absence of regulation of nonroad sources, the proportions listed in 2 above will
          probably increase in the future, as regulations are applied to more of the remaining
          source categories and are  further tightened on categories already subject to emission
          regulation.

   4.      Nonroad sources cannot be discounted as insignificant merely because they are outside
          the boundaries of nonattainment areas,

          Again, as the studies quoted in this chapter have demonstrated, ozone is a regional and
   not a local problem.  Airborne transport of ozone and its precursors does not stop at city,
   county, or state boundaries.  Apparently, it is not uncommon for transported pollutants to
   impact ozone levels 200 miles from the source of the emissions.  At this time, it is difficult to
   quantify precisely the distance ozone and ozone precursors typically travel, but clearly a
   complete list of sources contributing to urban nonattainment cannot stop at the nonattainment
   area's border.  Thus, nonroad sources outside nonattainment areas may be assumed to
   contribute to urban nonattainment.
          EPA and state officials are continuing to study the role of transport in nonattainment.
   Therefore, our understanding of transport should be considerably expanded within the next
   few years.  EPA's Office of Air  Quality Planning and Standards (OAQPS) is currently
   working on extensions to the results presented in the ROMNET draft study. These include

   applying the regional oxidant model to the Southeast and Midwest, in addition to modeling
   the effect of the Clean Air Act, as actually passed, on the Northeast. Much of this work will
   provide support to states containing nonattainment areas in their efforts to comply with the
   inventory and air quality modeling requirements of the Clean Air Act. OAQPS will also be
   working with the Northeast transport commission required by the Clean Air Act  to help them
   develop strategies for attainment. These regional models will continue to use existing
   national emission inventories, which, as discussed above, have some shortcomings in the area
   of nonroad emissions.  Currently, efforts are underway to establish a new national inventory
   for nonroad engines and other area and  mobile sources, called the Aerometric Information
   Retrieval System/Area and Mobile Source file (AIRS/AMS).  The results of these regional
   models will be re-evaluated using the new  inventories as soon as they are available in 1993.

   1.1.   Recreational Marine Equipment
          For the October draft of the nonroad study, EPA relied heavily on data supplied by
   NMMA from a survey conducted by Irwin Broh and Associates (D3&A) in eight
   nonattainment areas.  The results from this survey were used to adjust local boat registration
   data to represent actual usage in the nonattainment area (Inventories A and B), determine
   seasonal adjustment factors (Inventories A and B), and calculate annual hours of use, average
   horsepower, and load factors for Inventory B.
          In comments on the October draft of this report, NMMA requested the following
   technical revisions be made to activity levels:
          1.      Use an alternative methodology to determine boat usage based on the concept
                 of "saturation boating".
          2,      A methodology to extend the saturation boating concept to the 16 unsurveyed
                 areas.
          3.      Use fuel based activity levels (i.e., gallons/year) and emission factors (i.e.,
                 grams/gallon), rather than using horsepower-hour based factors.
          4.      Use national average fuel usage estimates, based upon the sales of a unique oil
                 formulation used to mix with 2-stroke outboard motor fuel.
          5.      Correct  an error in the calculation of average fuel usage from the survey.
          EPA made the following adjustments in response to NMMA's comments:
          1.  and 2. - Saturation boating methodologies - For Inventory B, a new methodology
   was developed for the 8 surveyed areas based upon the concept of saturation boating and
   extended to the 16 unsurveyed areas.  Specific equations for allocating boat populations using
   the concept of saturation boating were developed separately by EPA and NMMA.  The
   equation developed by NMMA was:

                                   F = 0.7 [1 - exp (-630A)]
          where:
                 F = fuel used in the nonattainment area as a fraction of the total fuel used by
                        boats  registered in the nonattainment area
                 A  = water surface area available for boating in the nonattainment area divided
                        by the number of registered boats in the nonattainment area.
FINAL - November 1991
-------
Nonroad Engine and Vehicle Emission Study
          The equation developed by EPA was slightly different:
                                    F=l -
          Overall, both formulas yielded similar results (the average ratio for all 24 areas was
   39% using NMMA's formula and 39.5% using EPA's), EPA's formula was used in
   developing Inventory B for the following reasons:
                 EPA's formula yielded better i2 values when regressed against the reported
                 usage ratios from the 8 surveyed areas (.32 vs. ,26 for NMMA's formula).
                 EPA's formula generated ratios closer to the calculated saturation limits for
                 those areas with high boat densities per nonattainment area water surface area.
                 NMMA's formula capped the ratio at a maximum of 70%, which may not be
                 appropriate for areas with very low boat densities per water surface area
                 (although only one of the nonattainment areas studied, Provo-Orem, falls into
                 this category)
                 NMMA's actual equation was not submitted until November 7, 1991 (the
                 concept was proposed several weeks earlier).
          NMMA specifically requested that this methodology be used for Inventory A, as well
   as Inventory B.  However, EPA was reluctant to totally ignore the  survey results from the
   IB&A survey. Instead, a compromise methodology was used for Inventory A.  The IB&A
   results  were used to estimate boat usage in each nonattainment area. This estimate was then
   compared to the calculated maximum summertime usage based upon saturation boating. In
   cases where the survey results yielded higher ratios than the calculated saturation ratio, the
   local estimates were adjusted downward to match the calculated saturation limits.  A more
   complete description of the methodology is contained in Appendix K.
          3.      Fuel-based activity levels - As recommended by NMMA, both Inventory A and
   Inventory B were revised from horsepower-hour based calculations to fuel use.  Descriptions
   of how this was done are contained in Appendix I (for emission factors), K (for Inventory A
   fuel use), and N (for Inventory B fuel use).
          4.      National average fuel use estimates - The national annual average of 91 gallons
   per outboard powered boat calculated by NMMA was used for the  16 unsurveyed areas for

   Inventory B.  The fuel usage for the other recreational marine equipment types was also
   adjusted for these areas using the outboard ratio of 91 gallons per year to the reported survey
   results of 142 gallons per year (i,e., 91/142).  No adjustments were made to the reported
   survey results for the eight surveyed areas, or to any  areas for Inventory A (fuel usage for
   Inventory A is based upon information supplied by PSR and BSFC calculations from data
   supplied by NMMA, not upon IB&A survey results).
          5,     Error in fuel usage calculations - The error reported by NMMA in calculation
   of fuel usage from the ffl&A survey was corrected and the results recalculated. This
   primarily affected the calculation of the proportion of boat use in the nonattainment areas for
   Inventory A (lowering the calculated number of boats used in the nonattainment areas by
   about 15%).

   1,2.    Lawn and Garden Equipment
          EPA received numerous comments from OPEI and PPEMA.  The following comments
   were all incorporated into Inventory B  and, as noted, into Inventory  A.
          1.     Annual hours of use adjustments for commercial use - OPEI commented that
   the splits between consumer  and commercial populations they had supplied for the draft
   report were erroneously reported  as population splits instead of sales splits.  The correction
   roughly halved the commercial populations, with the following impact on the multiplicative
   adjustments to consumer annual hours  of use to reflect the much higher annual usage of
   commercial equipment:

                       Tiller                      x2.2          xl.54

          These corrections  apply to both Inventory A and Inventory B.
          2,     Load factors for lawn and garden tractors - OPEI pointed out that load factor
   adjustments based upon their letter of September 9, 1991 from John F, Linskey to Clare  Ryan
   of EPA had not been incorporated into the draft.  This has been corrected  in the final report,

   dropping die Inventoiy B load factors from .47 to .38 for lawn and garden tractors, rear
   engine mowers and front mowers.
          3.      Horsepower estimates  - OPEI commented that errors had been made in their
   submittal of horsepower ranges for lawn and garden tractors and that 2-stroke snowblowers
   are smaller than 4-sttoke.  Based upon new data supplied by OPEI, Inventory B horsepower
   estimates for lawn and garden tractors dropped from  15.4 to 13,32 and 2-stroke snowblowers
   from 5.1 to 3,75.
          4.      Local disaggregation of handheld equipment population - While PPEMA had
   previously submitted population estimates for hand-held equipment (i.e., chain saws, blowers,
   trimmers/edgers),  for the October draft this equipment was disaggregated to the local level
   using the general lawn and garden methodology developed for Inventory A. PPEMA
   subsequently developed a population disaggregation model for hand-held equipment using
   state-level shipment data and rural, suburban, and urban population splits.  PPEMA used this
   method to directly calculate local equipment populations for chain saws, blowers, and
   trimmer/edgers. These local population estimates have been incorporated into Inventory B.
   In addition, as chain saws have very different usage patterns from most lawn and garden
   equipment (i.e., virtually no individual use by urban residents), the methodology developed by
   PPEMA was also used to disaggregate local chain saw populations for Inventoiy A.
          EPA received two comments specifically relating to lawn and garden activity levels
   that have not been incorporated into the final report.   Fust, OPEI commented that the
   population data for tillers in Inventory A was about 40% higher than in  Inventory B, and
   asked that Inventoiy A be reduced.  Although OPEI certainly knows how many tillers their
   members sell each year, this is not the same  as knowing the population. Engine useful life,
   annual  hours of use, scrappage rates, and consumer/commercial splits all affect equipment
   populations. PSR uses different methods of estimating populations man OPEI.  In most cases,
   PSR and OPEI generated similar population estimates. There is no available information
   identifying one population estimate as being  clearly superior to the other.  Thus, using one
   method for Inventory A and the other for Inventory B is the most equitable solution.
          The second comment that was not incorporated was on tiller load factors.  Briggs  and
   Stratum submitted information on the load cycle of several types of equipment. Most of this
   information either supported the CARB estimates or has been incorporated into Inventory B

—                                                     ,                  FINAL - November

   load factors.  The exception was tiller load factors.  CARB estimated a load factor of 40% for
   tillers.  The data submitted by Briggs and Stratton was interpreted to yield a load factor of
   only 20%.  However, the dynamometer test used to determine the load on the engine
   indicated that the engine used .24 gallon/hour to generate only 0.6-0.7 horsepower.  This
   equates to a BSFC of .34-.4 gallons/horsepower-hour, far higher than expected for these
   engines.  A tiller engine using .24 gallons/hour should generate at least twice this amount of
   power; which would be in line with a 40% load factor.

   1.3.   Recreational Equipment
         IS1A commented that there are no 4-stroke gasoline snowmobile engines in operation
   in the United States. In response to this comment, the final report assumes that all
   snowmobiles use 2-stroke gasoline engines for both Inventory A and Inventory B, despite the
   fact that EPA contractors reported a very small number of 4-stroke engines.

   1.4.   Industrial Equipment
         The hours of use for forklifts used in the draft report for Inventory B were based on a
   statement by ITA in its comments concerning the workshop held by EPA on April 3-4, 1991,
   "A typical light-duty forklift truck may be run for 40 hours per week for an average of
   2000 hours per year." In its response to the  draft report, ITA commented that by "typical" it
   did not mean average, and stated that 850 hours is the correct average use rate. EPA adjusted
   the hours of use  for forklifts in  Inventory B to 850 hours for the final report.

   1.5.   Agricultural Equipment
         EMI submitted data for combines and agricultural tractors which was used in the draft
   version of this study to construct Inventory B.  This data included population figures
   developed by the U.S. Bureau of Census, which EMI has stated may include seldom-used
   equipment. EMI has cautioned mat, in constructing an emission inventory, appropriate
   corrections should  be made to either die operative population estimate  or the  estimate of
   average annual usage.  EMTs submitted data contained no such correction.  In comment on
   the draft version of this study, EMI stated that the Inventory B results  for agricultural
   equipment  are significantly overstated because  EPA did not apply the downward adjustments

FINAL - November 1991
-------
Noaroad Engine and Vehicle Emission Study
   needed.  As EPA does not have any information on how to apply such downward
   adjustments, EPA has used the same data for Inventory B as used for Inventory A for these
   two types of equipment in this final report.

   1.6.    Construction Equipment
          Payhauler commented that the draft report contains large distortions in the construction
   equipment/mining category populations in nonattainment areas, in large part as a result of
   difficulties arising from the use of product sales and/or industry statistical information in
   estimating equipment populations.  Payhauler listed a number of factors which could increase
   the possibility of error, including confused product descriptions in the sales record, products
   are frequently short term rental fleets and moved around the country, and the county of sale is
   not likely to be the county or even state of use.
          No adjustments were made to the final report in response to Payhauler's comments for
   two reasons.  First, EPA does not have any data on which to base such adjustments, nor did
   Payhauler provide any data. Second, product sales were used in this report only to establish
   state or national level populations. These populations were disaggregated to the local level
   using local construction activity indices.  Thus, the local population figures should reflect the
   movement of products around the country to actual jobsites.

   2.     Emission Factors
          EPA received comments from several industry associations, including OPEI, NMMA,
   EMA, PPEMA, and FTA, regarding the emission factors used in die  study. One of the
   common concerns among the industry associations was related to the development and use of
   adjustment factors which were applied to new engine emission factors  to estimate in-use
   emission rates.  The associations were especially concerned with the limited data that were
   used to develop the adjustment factors for the equipment categories  they represented and
   suggested that in-use factors should not  be applied until more data is collected.
          EPA realizes that the in-use adjustment factors are based on  limited data and could be
   unproved when additional in-use engine testing is completed.  However, the in-use
   adjustments are EPA's best estimates based on existing data, and are clearly superior to the
   default of zero in-use deterioration, which would result if no in-use factors were applied.  In

                                                                      Response to Public Comment
   addition, the inventories in this study are presented two ways, with the in-use adjustment
   factor applied, and also without the in-use factor applied. This is done by the use of stacked
   bar charts  which readily show the additional contribution of emissions from the in-use
   adjustment estimates.
         The in-use adjustment factors for 2-stroke outboard motors in the draft study report
   were adjusted downward to 1.2 for HC  and CO (from 1.5 for HC  and 1,3 for CO) for the
   final study report.  This is discussed in greater detail in Section 2.2.3. of Appendix I.  While
   the arguments presented by NMMA were persuasive as to the superior durability and
   maintenance of outboard engines, such that these in-use  adjustments were made  for the final
   report, they did not support a total lack of in-use engine wear and maimaintenance.
         Other comments regarding emission factors were more specific to certain equipment
   types. OPH was concerned that  the emission factors for snowblowers and commercial turf
   care equipment should be revised to better represent the horsepower ranges of these
   equipment.  Upon review of the emission factors in the draft study, EPA agreed that these
   factors warranted adjustment.  For snowblowers, the emission factors used for lawn mowers
   were used for the final  study report. For commercial turf care equipment, the emission
   factors for lawn and garden tractors were used.
         OPEI also presented sales data on the proportion of utility engines sold over the last 8
   years with open and closed crankcases.  Based on this data, the crankcase emission factors for
   lawn and garden equipment were revised to reflect 22% open crankcases (the draft report
   assumed 100% open crankcases).
         EMA expressed concern that the paniculate emission factors used in the draft study
   report were outdated.  The emission factors were derived from AP-42 and based on 1973 tests
   performed at Southwest Research Institute.  EMA suggested that the test results from a recent
   joint EPA/Industry program to assess test cycles for nonroad equipment be used to revise the
   paniculate emission factors as  well as NOX, HC, and CO emission factors. The  paniculate
   emissions  from the four 1991 diesel nonroad engines tested suggest that these newer engines
   have considerably lower paniculate emission rates than  the emission factors reported in AP-
   42. To  reflect this concern, the paniculate emission factors used  for Inventory B are the
   equally  weighted average of the  AP-42 emission factors and the 1991 EPA/Industry average
   8-mode nonroad engine test data. However, because there is no way to determine when

FINAL November 1991
-------
Nonroad Engine and Vehicle Emission Study
   diesel engines began to emit lower amounts of participates, the paniculate emission factors
   for Inventory A remain those reported in AP-42. A more complete discussion of this is
   contained in Section 1.2.1, of Appendix I.
          Another main area of concern for EMA related to the adjustment factor used to
   convert from steady state emission factors to in-use (transient) emission factors.  EMA
   suggested that the adjustment factor should be corrected to a value halfway between the
   steady state and on-highway transient values instead of a correction all the way to the on-
   highway transient, as was done in the draft study report. However, although the transient
   cycle used to simulate highway heavy-duty engine operation may not be as appropriate to
   simulate nonroad equipment transient operation, EPA expects that it is a better representation
   of nonroad equipment that encounters transient operation in use than the 8 -mode steady state
   test (it should also be noted that no adjustments were made for equipment types expected to
   primarily, but not exclusively, encounter steady state operation).  EPA realizes that different
   equipment types have varying degrees of transient and/or steady state operating characteristics
   in-use.  However, it was beyond the scope of this study to characterize the in-use operating
   cycles of the  numerous equipment types included in the study.  Therefore, the final study
   report continues to reflect the on-highway transient adjustment for those equipment types
   expected to encounter transient operation in use and no adjustment for those equipment types
   expected to primarily encounter steady  state operation.
   3.      Additional Considerations/Other
          This section summarizes comments received that were not directly related to activity
   levels or emission factors.

   3.1.    Use of Equipment Categories
          EPA received comments from EMI and NMMA requesting clarification of EPA's use
   of equipment categories in constructing emission inventories.  Both were concerned that the
   categories used for this study could be construed as potential regulatory categories.
          EPA considered over 80 different types of equipment in this report, many of which are
   highly specialized and have low sales volumes. EPA grouped the equipment types into 10

-------
                                                                      Response to Public Comment
   equipment categories only to assist the disaggrcgation of national or state equipment
   populations to the local level, and to ease analysis and repotting of inventory results,  EPA
   has revised the final report to clarify that these categories are not intended to represent
   potential regulatory categories.

   3.2.   Inclusion of Two Sets of Inventories
         EPA received a request  for clarification of the use of two inventories from EMI, and
   two manufacturer associations expressed concern about data on which Inventory A is based.
   FT A expressed concern about lack of access to PSR data and methodology and uncertainty
   about what is included in Inventory A populations,  EMI expressed concern about the method
   used in Inventory A of estimating equipment populations using engine shipment data.
         PSR is a commercially available marketing research data base, and the EEA
   methodology  is based on publicly available indices of commercial activity.  Although several
   manufacturers expressed their belief that PSR was not accurately estimating equipment sales,
   in every case where manufacturers were willing to divulge equipment sales data to PSR or
   EEA (12 cases total), PSR's estimates showed excellent agreement with the equipment sales
   data (usually  within 5%). In addition, much of the data used in Inventory A was not
   available from any other source.
         EPA also developed a second set of inventories, Inventory B, which relies on
   manufacturer-provided data for almost all high usage equipment types.  This industry-
   provided data might not be  publicly available to states, but does give EPA a valuable cross
   check for the first set of inventories.  In general, EPA regards both inventories as being
   equally appropriate estimates of nonroad populations and activity rates, and has learned a
   great deal  from the ways in which they differ and agree.

   3.3.  Transportable Equipment
         EMA  commented that EPA should include all transportable equipment (e.g.. generator
   sets, compressors, pumps),  as well as self propelled, in the nonroad emissions inventory.  It is
   EMA's position that both fall exclusively within the scope of nonroad mobile engines and
   vehicles, and that both are within the scope of EPA's authority under Title II of the Clean ALT
   Act.  EMA states further that EPA can only make a determination to regulate engines used m

FINAL - November 1991                                                                     «,
-------
Nooroad Engine and Vehicle Emission Study
   transportable equipment based on the nonroad study, and that by failing to include all
   transportable equipment in the study, EPA has failed to meet the mandate imposed on it by
   Congress.
          There were several types of equipment that are not  included in this study due to lack
   of data, not just transportable equipment.  For example, mining equipment also is not
   included in the study.  Transportable equipment below SO hp are included in the study, but
   transportable equipment over 50 hp are not due to lack of data and potential conflict with
   stationary source requirements.
          EPA does not agree that the exclusion of equipment types from the study either
   prohibits EPA from regulating such equipment as nonroad engines or violates  the mandate
   imposed by Congress. Congress required EPA to regulate nonroad engines if  nonroad
   emissions are determined to be significant based on this study.  However, this is a one-way
   requirement; it does not forbid EPA from regulating nonroad engines under other
   circumstances. Further, while Congress mandated mat the determination of significance be
   made for nonroad engines as a whole based on this study, the regulatory requirements are for
   EPA to ". . . promulgate (and from time  to time revise) regulations containing standards
   applicable to emissions from those classes or categories of new nonroad engines and new
   nonroad vehicles (other than locomotives or engines used in locomotives) which in the
   Administrator's judgement cause, or contribute to, such air pollutants,"  Nothing in this
   language restricts  EPA to only those classes or categories included in this study or prohibits
   EPA from updating the assessment of emission contributions in the future.

   3.4.    2-Stroke Marine VOC Emission Reactivity
          NMMA submitted the claim that  VOC emissions from 2-stroke marine engines are
   less photochemically reactive than other  forms of VOC emissions.  However,  NMMA did not
   submit any data substantiating this claim.
          VOC reactivity is a very complicated process. While an important consideration is
   ozone formation, the reactive processes are far from completely understood.  Thus, EPA does
   not have sufficient information to judge  the validity of NMMA's claim. Without data
   substantiating the overall reactivity of unbumed fuel, EPA must use the standard assumption
   that  the VOC reactivity of motor vehicle emissions are relatively similar.

   3.5.    Conclusions Chapter
          NMMA commented that the nonroad study is a technical report and, as conclusions
   are best left for the regulatory process, suggested that EPA remove Chapter 5 from the report.
          The purpose of the conclusion chapter is to highlight major points and to identify the
   points that EPA considers to be most important.  No pan in the conclusions is intended to be
   other than a summary of the data presented in the report. Thus, EPA does not agree that it
   should be removed.

   3.6.    Consideration of Updated Information
          NMMA requested that EPA make a clear statement in the report recognizing the
   possibility that improved data may result in changes to the inventories, and that such data, if
   available and  credible, will be used by EPA in the determination of significance and any
   subsequent regulatory process.
          Updated data will not necessarily be used in the determination of significance; nor will
   it be arbitrarily excluded.  However, EPA agrees with the statement that any subsequent
   regulatory activity will incorporate new information. While EPA does not believe this
   statement needs to be in the body of the report, it is  acknowledged here.

   3.7.    Transport
          In their comments, NMMA and OMC brought up several issues that complicate the
   estimation of  the impact of transported VOC emissions on urban nonattainment. For
   example, NMMA submitted a report compiled by Sierra Research questioning the impact of
   VOC emissions on ozone transport.  EPA does not necessarily agree  with all of these
   comments, however, the issues raised do illustrate the complex nature of transport,  and the
   difficulty of estimating precisely  the impact of relatively distant emission sources on any
   particular nonattainment area.  EPA did not include estimates of the impact of transported
   emissions on  urban nonattainment in the final quantitative inventory estimates in recognition
   of such difficulties. Reliable quantitative estimates of the impact of transported emissions
   from marine pleasure craft may become available as existing photochemical models such as
   the Regional  Oxidant Model (ROM) and the Urban Airshed Model (UAM) are further refined
   and applied to individual nonattainment areas in the next several years. EPA is not

   attempting to prejudge these results in this report, but merely intends to note that transported
   ozone or ozone precursors caused by marine pleasure craft used in rural areas and other rural
   sources may have an impact on urban air quality.  The principal conclusions of the impact of
   all nonroad sources on urban nonattainment contained in this report are based solely on
   emissions inside the nonattainment areas studied.
          In its comments, EMI asserts that transport from more rural  areas to urban areas
   cannot be considered to contribute to urban nonattainment because the concentration of ozone
   and ozone precursors is generally lower in rural areas. EMI states;  The common-sense
   observation is that if 'Air Mass B' moves into an airshed, then 'Air Mass A*, the ak already
   there, has to be moved." To this observation, EPA would add a second observation: that ak
   is not a solid.  Elementary principles of physics and meteorology would imply that as Ak
   Mass B enters an area, it mixes with Air Mass A, and that (assuming atmospheric pressure
   remains constant) some of this mixture exits the area. To the extent that Air Mass B contains
   air with lower concentrations of ozone and ozone precursors than Air Mass A, this mixing
   will lower the concentration of ozone  in the urban area.  However,  the effectiveness of this
   mixing in lowering the concentration of ozone in the urban area is dependent on the
   concentration of ozone and ozone precursors in the entering Air Mass B, and not merely on
   the fact that this concentration may be lower than the concentration in the preexisting Ak
   Mass A.
          To illustrate this principle, let us assume first that Ak Mass B contains no ozone or
   ozone precursors. Clearly, then, the concentration of ozone and ozone precursors in the
   mixture of Air Mass A and Ak Mass B would be much  lower than the concentration in Ak
   Mass A before it was diluted. On the other hand, we could consider a case where Ak
   Mass B has concentrations of ozone and ozone precursors that are only slightly lower than
   those concentrations in Ak Mass A.  Under this scenario, the concentrations of ozone and
   ozone precursors in the mixture would be nearly die same  as those  concentrations in the
   urban Ak Mass A.  Thus, emissions of ozone precursors into a rural ak mass can have a
   deleterious impact on urban ak quality by reducing the ability of prevailing winds from rural
   areas to dilute the pollution in urban ak.
          These conclusions were borne  out by the EPA study entitled "Regional Oxidant
   Modeling for Northeast Transport", or "ROMNET". This study was based on a detailed

   photochemical ak quality model (the Regional Oxidant Model or ROM) for the northeastern
   quadrant of the U.S.  EMI has urged elsewhere in their comments that EPA apply this ROM
   model to the study of emissions from nonroad sources specifically,  ROMNET traced the
   formation of ozone levels in the major northeastern urban areas during specific ozone
   episodes by incorporating detailed information on emissions and meteorological conditions
   prevailing during those episodes. The ROMNET study incorporated emissions from nonroad
   sources  along with all other sources of ozone precursors. The study was specifically designed
   to determine if transport from the western, generally rural part of the ROMNET region (e.g.,
   Ohio, western Pennsylvania) had a negative impact on air quality in the major coastal  urban
   areas (e.g., Philadelphia) during conditions that were known to have produced an actual
   exceedance of the ozone standard.  The study concluded that this transport did, in fact,
   contribute to nonattainment of the ozone standard in the coastal areas, despite the fact that
   actual levels of ozone and ozone precursors in an air "packet" as it  passed over the more
   western areas were considerably lower than the levels of ozone and ozone precursors in that
   air "packet" as it passed through the coastal urban areas.
         Elsewhere in the Clean Air Act, Congress apparently concurred with the conclusion
   that emissions in rural areas can contribute to urban nonattainment.  In Section 184  of the
   Clean Ak Act, Congress explicitly created an Ozone Transport Commission comprising 11
   northeastern states and the District of Columbia.  Congress had concluded that the transport
   of ozone and ozone precursors in this region was so significant mat the air pollution control
   policies of these states should be coordinated to insure their fairness and effectiveness.
   Included by law in the Ozone Transport Commission is the State of Vermont, a rural state
   with no ozone nonattainment areas.

   3.8.    Determination of Significance/Air Quality Analysis
          EMI suggested mat the October draft does not provide sufficient information for a
   determination of significance.  EMI believes that:
          "In order to meet the requirements of Section 213(aX2) the CAA with respect
          to a determination of significance, an ak quality analysis which takes into
          account heterogeneity in the geographical distribution of nonroad engines/
          vehicles, seasonal factors, transport and other atmospheric variables,  and which
          includes photochemical modeling, is required."

Nonroad Engine and Vehicle Emission Study
          As EMI discusses at some length in their comments, EPA does not base the
   contribution of nonroad engines to ambient air quality problems on photochemical air quality
   modelling in this study. EPA reiterates its previous position that photochemical modelling is
   not required to draw valid scientific conclusions about the contribution of nonroad emissions
   to nonattainment, and that Congress did not intend to require EPA to construct such models.
          In the nonroad study, EPA has assumed that the contribution of nonroad sources to the
   concentration of ozone during a nonattainment episode is proportional to the contribution of
   nonroad sources to the total amount of VOCs and NOX emitted in that area by all sources.
   This is the approach that has historically been taken  by EPA in determining the contributions
   of different sources to nonattainment and in estimating the general effectiveness of nationwide
   air pollution control measures.  It is based on the widely accepted scientific position that
   urban ozone is formed by the reaction of VOCs and NOX in the presence of sunlight.
   Congress in  no way indicated that it intended for EPA to digress from this approach; in fact,
   the legislative history of the CAA clearly shows that Congress conceived of the relative
   significance  of nonroad sources in terms of their contribution to the total inventory of VOCs
   and NOX. The Senate Committee Report notes that  "[e]missions inventories from EPA
   estimate that farm and construction equipment emit 3.7 percent of CO nationwide, 4 percent
   of nationwide NOX, and 1.3 percent of total hydrocarbons." The Senate Report further states
   "While inventories of these emissions are not precise, estimates indicate the extent to which
   they contribute to ozone and other pollution problems."  (Senate Report No. 101-228, p. 104)
   Clearly, the  intended mandate of Section 213 is that EPA improve upon existing emissions
   inventories for nonroad sources and mat a conclusion about the significance of nonroad
   sources could be based on these inventories.
          Further, in placing a one-year deadline for die completion of the nonroad study, and
   an additional one-year deadline for issuing standards based on the results of the study,
   Congress indicated a certain urgency in addressing this long-neglected category of pollution
   sources.  The one-year deadline is one of only a very few  specific requirements for
   performing the nonroad study; in general, EPA was  not told how to perform the study, but
   rather to complete  it quickly.  This deadline  effectively precludes the time-consuming
   development of photochemical models.  The Regional Oxidant Model for Northeast Transport
   (ROMNET) study, which covers only the Northeast  quadrant of the U.S., took over five years

   to complete. An Urban Airshed Model of the Lake Michigan area is also expected to take
   several years to produce results. Due to the time and expense required to develop
   photochemical  models, Congress has required only states with serious, severe, and extreme
   nonattainment areas to include them in their State Implementation Plans for attainment of the
   ozone standard. These areas were given 4 years to complete State Implementation Plans;
   areas that were not required to include photochemical models were required by Congress to
   submit State Implementation Plans in 3 years (CAA Section 182).
          Finally, it is quite possible that Urban Airshed or Regional Oxidant Modelling would
   not offer any significant increase in our understanding of the significance of nonroad sources
   to the nationwide urban nonattainment problem.  These  models were developed primarily to
   help individual nonattainment areas determine the effectiveness of specific air pollution
   control measures, given highly detailed data and assumptions for the unique conditions
   prevailing in that area. Thus, the models could be used to assess whether a given proposal
   for reducing emissions from a type of nonroad source would be more effective in a given area
   than some other measure. However, emission control measures have not yet been proposed
   for any nonroad source and  Congress mandated that the nonroad emission study assess the
   impact of current inventories before  EPA issued  any such proposals.
