PNM San Juan Generating Station 

BART Analysis of SNCR 

May 30, 2008 

Introduction 

In a letter dated April 25, 2008, the New Mexico Environmental Department – 

Air Quality Bureau (NMED) commented that the NOx presumptive control level of 0.23 

lb/MBtu for the San Juan Generating Station (SJGS) can be modified to alternative NOx

emission levels in order to evaluate control technologies that that are less effective and 

that do not meet the required presumptive emission level. Based on this reasoning, 

NMED requested additional analyses be performed. Specifically, the NMED requested 

additional consideration and modeling of the Nalco-Mobotec ROFA and Rotamix, and 

Selective Non-Catalytic Reduction (SNCR) NOx control technologies. 

As described in the June 6, 2007 BART application document and in PNM’s 

March 31, 2008 response to NMED questions, the ROFA technology is a type of overfire 

air (OFA) system. As discussed in the March 31, 2008 filing, ROFA does not result in a 

lower NOx emission rate than the LNB/OFA systems currently being installed at SJGS. 

Since PNM has already evaluated the impact of LNB/OFA system as part of its previous 

BART submittals, no additional analyses were done for the ROFA technology. 

The Rotamix technology is a simply Nalco/Mobotec’s version of SNCR control 

technology. Therefore, it does not need to be evaluated separately from other vendors of 

SNCR technology. 

For SNCR technology the first three steps of the five step BART process were 

completed as part of the original BART submittal on June 6. 2007. However, because 

SNCR did not meet the presumptive limit of 0.23 lb/MBtu for subbituminous fuel, the 

last two steps were not completed. To review, the BART analysis is defined in the 

regional haze regulations and guidelines in 40 CFR Part 51. The following factors are 

considered when identifying the best method of emissions reduction: 

• Technical feasibility. 

• Cost of compliance. 

• Energy and non-air quality environmental impacts of compliance. 

• Existing pollution control equipment in use or installed at the source. 

• Remaining useful life of the source. 

• Degree of anticipated improvement in visibility. 

 
Final BART Response 053008.doc 2 of 11 

The BART analysis consists of the following five steps to arrive at a selection of 

the best methods of emissions reduction for a BART-eligible source: 

• Identify all available retrofit control technologies. 

• Eliminate technically infeasible options. 

• Evaluate control effectiveness of remaining control technologies. 

• Evaluate impacts and document the results. 

• Evaluate visibility impacts. 

The two parts of this document complete the last two steps of the BART analysis 

for SNCR. 

Part 1 - Engineering Impact Analysis 

 An engineering impact analysis was performed for the SNCR NOx control 

technology. The results of that impact analysis are shown in Attachment 1. Table 7-1 in 

Attachment 1 is an update to the Table 7-1 found in PNM’s original BART submittal of 

June 6, 2007. It has been updated to include the engineering impact of SNCR. In 

addition to Table 7-1, Attachment 1 also includes the Design Concept Definitions for 

SNCR and the detailed cost tables for installing SNCR on each unit at the SJGS. 

Part 2 – Visibility Analysis 

Subsequent to the June 6, 2007 submittal, PNM further investigated additional 

refinements to the BART CALPUFF air dispersion modeling analyses which included 

nitrate repartitioning and more realistic ammonia background concentrations based on 

monitored values at several western Class I areas. These additional modeling options are 

considered more realistic and therefore will again form the basis of this analysis. 

To date, PNM has previously submitted three BART modeling analyses. To 

clarify the contents of these analyses, as well as for this submittal, a summary of each has 

been provided: 

June 6, 2007

Modeling analysis were performed to provide SJGS plant-wide regional haze 

(visibility) impacts at 16 Class I areas. The analyses were based on a constant 1 

ppb background ammonia concentration and no nitrate repartitioning. The NOx 

control technologies analyzed were the Selective Catalytic Reduction (SCR) and 

SNCR/SCR Hybrid. 
Final BART Response 053008.doc 3 of 11 

November 6, 2007

Modeling analysis were performed to provide SJGS plant-wide regional haze 

(visibility) impacts at 16 Class I areas. The analysis was based on refinements 

which included using the nitrate repartitioning methodology and monthly variable 

background ammonia concentrations. Again, the NOx control technologies 

analyzed were the SCR and SNCR/SCR Hybrid. 

March 31, 2008

Two main modeling analyses were performed to provide SJGS plant-wide and 

unit specific regional haze (visibility) impacts at 16 Class I areas for the SCR NOx

control technology only. One of the analyses, believed to be the more 

representative of ammonia chemistry of the area, was based on the November 6, 

2007 refinements which included using the nitrate repartitioning methodology and 

monthly variable background ammonia concentrations. The other analyses 

included nitrate repartitioning and a constant background ammonia concentration 

as requested by the NMED. 

May 30, 2008

Two modeling analyses were performed to provide SJGS plant-wide and unit 

specific regional haze (visibility) impacts at 16 Class I areas for the SNCR NOx 

control technology only. Similar to the March 31, 2008 analyses, one of the 

analyses was based on the November 6, 2007 refinements which included using 

the nitrate repartitioning methodology and monthly variable background ammonia 

concentrations. The other analyses included nitrate repartitioning and a constant 

background ammonia concentration. It should be noted that all vendors of SNCR 

(including Fuel Tech and Nalco/Mobotec) have been modeled together as one 

technology called SNCR. This is the same approach that is used for modeling 

SCR control technology, where all vendors are modeled generically as SCR. 

The modeling refinements contained in this submittal using nitrate repartitioning 

and the variable ammonia background, as well as the November 2007 and March 2008 

submittals, supersedes the original June 2007 BART modeling analyses as PNM believes 

these analyses are more representative. Therefore, the purpose of this section is to again, 

summarize the two refinements used and to provide supplemental information on the 

background ammonia data. Lastly, the document will summarize the SJGS plant-wide 
Final BART Response 053008.doc 4 of 11 

and unit specific modeling for the SNCR control technology scenario using nitrate 

repartitioning and a both a variable and constant ammonia background. 

Nitrate Repartitioning 

The first refinement for the SJGS BART visibility analyses (included in the 

November 2007 submittal) was to better account for the amount of particulate nitrate 

(NO3) by limiting the available ammonia when individual unit puffs overlap. The 

original visibility modeling conducted for the June 2, 2007 BART application did not 

incorporate repartitioning of available ammonia (MNITRATE = 0). The refinements did 

not allow each overlapping puff(s) to use the full ammonia background value but instead 

only a portion of the ammonia available (MNITRATE = 1). This concept is reflected in 

Section 3.1.2.6 of the WRAP protocol. It is important to note that this refinement noted 

as nitrate repartitioning is not the ammonia limiting method commonly referred to as 

ALM. 

Ammonia Background Concentration 

As described in Section 8.1 of the BART application, the air dispersion modeling 

analyses presented were conducted in accordance with the CALMET/CALPUFF Protocol 

for BART Exemption Screening Analysis for Class I Areas in the Western United States

dated August 15, 2006, (hereinafter referred to as the WRAP Protocol). Specifically, the 

initial SJGS BART modeling for the June 6, 2007 BART Application was performed 

using the same high fixed background ammonia level of 1 ppb that was used for the 

initial modeling performed by WRAP RMC. However, there is limited real-time or 

historic ambient concentration information for ammonia within the modeling domain and 

at the individual Class I areas from sources such as CASNET. As a result, there is 

limited information to use to verify whether the assumed 1 ppb ammonia background 

concentration is representative. In fact, colder temperatures and limited agriculture 

activity, among other variables, could limit the amount of ammonia present in the 

ambient atmosphere, thus limiting the ammonia available to chemically react to form 

sulfates and nitrates to reduce visibility. Section 3.1.2.6 of WRAP protocol indicates that 

the 1 ppb value would be initially used and the issue revisited at a later time: 

Thus, based on the fact that western Class I areas tend to be either more arid or 

forest land than grassland we proposed to initially use a 1 ppb background 

ammonia value for the CALPUFF runs. We will then revisit the background 

ammonia values for the Class I areas for the post processing step and provide the 

CALPUFF output to the States so they can investigate alternative background 

ammonia values if desired.
Final BART Response 053008.doc 5 of 11 

No additional information from the WRAP regarding refined ammonia 

background concentrations was available. Therefore, an investigation was undertaken to 

locate more realistic ammonia background values. The Sithe Global Power, LLC’s 

Desert Rock Energy Facility and the Toquop Energy Project visibility analyses located in 

the southwestern U.S. used variable monthly background ammonia concentrations. 

Based on this information, refinements to SJGS’s BART modeling (included in the 

November 2007 and March 2008 submittals) reflected these previously used and 

approved values. These background ammonia concentrations are presented in Table 1 for 

reference. These data were based on ammonia background concentrations monitored at 

several western class I areas.

The ammonia data and supporting information

visibility analyses were included in detail in 

Attachment 1 of the March 31, 2008 report 

submittal. 

Additionally, Table 2 contains a monthly summary of actual monthly monitored 

ammonia data from a long term ammonia air monitoring study in western Wyoming. 

This monitoring study, located in the Upper Green River Basin of western Wyoming 

southwest of Bridge Wilderness Area, was initiated in December 2006 by Shell 
Final BART Response 053008.doc 6 of 11 

Exploration & Production Company and continued for 15 months. The findings of this 

study were presented at the Air & Waste Management Association (AWMA) Aerosol & 

Atmospheric Optics: Visual Air Quality and Radiation in Moab Utah on May 1, 2008. 

The extended abstract for this presentation has been included as Attachment 2. As Table 

2 illustrates, these monthly mean ammonia values (referenced from Figure 2 of the 

abstract) have the same monthly trends as the ammonia data used in PNM’s previous 

modeling submittals (November 2007 and March 2008 submittals). This data is 

representative of another western area similar to that of northwestern New Mexico are 

much less than those values currently assumed in the PNM modeling. In fact, the annual 

average ammonia value is 0.24 ppb. This data has been included for illustration purposes 

only and again reiterates the premise that the 1 ppb constant ammonia value is 

conservatively high and not representative of actual ammonia in the area of the SJGS.

Visibility Summary 

Based on the aforementioned refinements in background ammonia concentrations 

and nitrate repartitioning, revised CALPUFF visibility modeling was performed for three 
Final BART Response 053008.doc 7 of 11 

cases; pre-consent decree, consent decree (which represents SJGS’s BART baseline 

scenario), and the SNCR control technology scenario. The modeling summarized in this 

report is for the SJGS on a plant-wide basis and for each of the four SJGS units on an 

individual unit basis. It is important to note that all other modeling options as described 

in the BART application were unchanged. For simplicity, the following results discuss 

the differences between the consent decree scenario and the SNCR scenario. The 

visibility modeling results are contained in Attachment 3. 

SJGS Visibility Summary with Nitrate Repartitioning and Variable Ammonia

The results of the refined visibility modeling for the SJGS plant, assuming the 

same SNCR control technology is installed on all four units, are illustrated in Tables 1 

through 4 of Attachment 3. These tables summarize the scenarios and the maximum 

visibility (deciview) impact seen at any of the 16 Class I areas at any time over the 2001 

to 2003 period. The results of this analysis, using the aforementioned refinements, 

indicates a minimal improvement in visibility impact at each of the 16 Class I areas. 

 The maximum visibility (deciview) improvement seen at any of the 16 Class I 

areas at any time over the 2001 to 2003 period is illustrated in Table 4 for each scenario. 

The expected degree of visibility improvement for each control scenario for each unit (on 

a plant-wide basis) was determined by the difference in the maximum visibility 

improvement for each receptor at each of the sixteen Class I areas. Again, it is important 

to note that the control technology associated with the consent decree formulated the 

SJGS’s baseline case, as well as the baseline case for the individual unit analyses 

described later. Additionally, the cost-effectiveness for the potential BART control 

technologies from the BART application were used to calculate visibility improvement 

cost-effectiveness in $/deciview ($/dv). Three major scenarios are shown in the 

visibility improvement cost effectiveness summary in Table 4: 

• Pre-consent decree to consent decree. 

• Consent decree to additional SNCR NOx control technology alternatives scenario. 

• Pre-consent decree to additional SNCR NOx control technology alternatives 

scenario. 

These maximum visibility improvements between the consent decree and the 

SNCR control scenario range from 0.04 dv to 0.21 dv of expected visibility improvement 

above the consent decree scenario. The results indicate that adding additional SNCR 

NOx control technology beyond the consent decree does not yield visibility improvement 

greater than 0.5 dv at any Class I area. In fact, as previously noted, the maximum 

visibility improvement at any of the 16 class I areas is only 0.21 dv which is considered 

insignificant. 
Final BART Response 053008.doc 8 of 11 

Based on the visibility improvement modeled and the total annual cost evaluated 

in the impact analysis stage of the BART application document, the cost-effectiveness for 

visibility improvement (annual cost per improvement in visibility, $/dv), was determined 

for SJGS over the aforementioned range of visibility improvement. The resulting cost for 

installation of SNCRs for all four units ranges from $354 million/dv to $75 million/dv. 

Attachment 3 contains a SJGS plant-wide summary of the 98th percentile visibility 

impact for the three modeled technology scenarios (i.e., Pre-Consent Decree, Consent 

Decree, SNCR scenarios), provides information on the number of days above 0.5 dv 

threshold, and indicates the contribution of each pollutant associated with the 98th

percentile visibility impact for each class I area. 

Unit Specific Visibility Summary with Nitrate Repartitioning and Variable 

Ammonia

The results of the refined visibility modeling for Unit 1, Unit 2, Unit 3, and Unit 4 

are illustrated in Tables 5-8, 9-12, 13-16, and 17-20 of Attachment 3, respectively. These 

tables summarize the scenarios and the maximum visibility (deciview) impact seen at any 

of the 16 Class I areas at any time over the 2001 to 2003 period. Similar to results seen 

for the SJGS facility, the visibility impacts at Mesa Verde represent the maximum 

visibility impact at any of the 16 Class I areas. In addition, this analysis indicates a 

minimal improvement in visibility impact at each of the 16 Class I areas. 

The maximum visibility (deciview) improvement seen at any of the 16 Class I 

areas at any time over the 2001 to 2003 period is illustrated in Tables 8, 12, 16, and 20. 

Again, the expected degree of visibility improvement for each control scenario for each 

unit was determined by the difference in the maximum visibility improvement for each 

receptor at each of the sixteen Class I areas. Furthermore, the same methodology 

previously described for the SJGS’s cost-effectiveness in ($/dv) was used here for each 

unit. 

These maximum visibility improvements between the consent decree and the 

SNCR control scenario for each unit are similar to that of the combined SJGS. The 

visibility improvements are summarized below. 

• Unit 1 improvements range from 0.02 dv to 0.16 dv. 

• Unit 2 improvements range from 0.02 dv to 0.16 dv 

• Unit 3 improvements range from 0.02 dv to 0.15 dv 

• Unit 4 improvements range from 0.0 dv to 0.15 dv 
Final BART Response 053008.doc 9 of 11 

The results again indicate that adding additional SNCR NOx control technology 

beyond the consent decree does not yield visibility improvement greater than 0.5 dv at 

any Class I area. Based on the visibility improvement modeled and the total annual cost 

evaluated in the impact analysis stage of the BART application document, the costeffectiveness for visibility improvement (annual cost per improvement in visibility, $/dv), 

was determined for each unit for each Class I area. The resulting cost for installation of 

SNCRs for each unit is summarized below. 

• Unit 1 cost range is $225 million/dv to $21 million/dv. 

• Unit 2 cost range is $225 million/dv to $21 million/dv. 

• Unit 3 cost range is $287 million/dv to $30million/dv. 

• Unit 4 cost range is $2.3 billion/dv1 to $29 million/dv. 

Attachment 3 contains a unit specific summary of the 98th percentile visibility 

impact for the three modeled technology scenarios (i.e., Pre-Consent Decree, Consent 

Decree, SNCR scenarios), includes the number of days above 0.5 dv threshold, and 

indicates the contribution of each pollutant associated with the 98th percentile visibility 

impact for each class I area. 

Visibility Summary with Nitrate Repartitioning and Constant Ammonia

As previously noted, the purpose of this analyses, and the previous November 

2007 and March 2008 analyses, was to perform visibility modeling using refined 

methodologies from those contained in the original BART submittal. However, PNM 

recognizes that NMED has previously requested additional visibility modeling be 

conducted using a constant ammonia background value of 1 ppb. While PNM does not 

believe analyses conducted using the constant ammonia background (1 ppb) is 

representative, analyses have been conducted based on the aforementioned modeling 

methodology and described scenarios for both the SJGS plant and individual units. The 

results of this analysis can be found in Attachment 3, Tables 21-40. 

Attachment 3 also contains tables summarizing the modeling results, the summary 

of the 98th percentile visibility impact for the three modeled technology scenarios (i.e., 

Pre-Consent Decree, Consent Decree, and SNCR scenarios), and the number of days 

above 0.5 dv threshold and the contribution of each pollutant associated with the 98th

percentile visibility impact for each class I area.

 The visibility improvement realized for Unit 4 is 0.002 dv but is illustrated in Attachment 3, Table 20 as 

0.00 dv.

Additional Considerations

The minimal visibility improvements discussed in this document for the variable 

ammonia case (or even the constant ammonia case) do not merit the large capital 

expenditure required to install SNCR. In addition to the prohibitive cost associated with 

SNCR, there are other important reasons that LNB, OFA and NN should be considered 

BART for the SJGS units. First, the LNB, OFA and NN systems being installed to meet 

the consent decree are state-of-the-art combustion controls. State-of-the-art combustion 

controls comprising of LNB, OFA and NN technologies were used to form the basis for 

the BART presumptive limits for NOx in the BART guidelines. Second, installation of 

SNCR requires ammonia to reduce NOx emissions. Specifically, in a SNCR system, 

ammonia is injected into the boiler. Any unreacted ammonia passes through the boiler 

and out the stack as ammonia emissions or ammonia slip. This additional ammonia 

would then be available to add to the ammonia background concentration, chemically 

react to form nitrates and sulfates, and potentially further increase the visibility impacts at 

the Class I areas. The additional ammonia slip was not considered in this analysis. 

Finally, the visibility results imply that visibility is influenced more by the SJGS’s sulfur 

emissions than by the reduction of NOx. However, sulfur emissions are not subject to 

BART requirements because New Mexico participates in the WRAP emissions trading 

program. Therefore, LNB, OFA and NN should be considered BART for NOx control on 

the SJGS units. 

Conclusion

As noted in this document, PNM’s further investigation of additional refinements 

to the June 2007 BART CALPUFF air dispersion modeling analyses to yield more 

realistic regional haze impacts was warranted. These analyses included nitrate 

repartitioning and more realistic ammonia background concentrations based on 

monitored values at several western Class I areas, as well as, the additional ammonia 

study from western Wyoming. The conclusion of this study re-iterate and further support 

the overall findings of the June 2007 that installation of SNCR systems at the SJGS 

provide minimal visibility improvements and would require significant capital 

expenditure and modifications that will impact many areas of the plant including boiler 

draft systems, air heater performance, and ash handling. The results from the analyses 

further substantiate that the addition of SNCR technology does not yield a benefit nor 

meet the intended goal of BART. Specifically, these analyses indicate: 
Final BART Response 053008.doc 11 of 11 

• The addition of SNCR technology on a plant-wide or individual unit basis shows 

less than a 0.5 dv improvement for all Class I areas including the four Class I 

areas located in New Mexico. 

• Both the total annual costs evaluated and the cost-effectiveness ($/dv) are 

prohibitive given the minimal improvements realized. 

Therefore, as previously noted, given the minimal visibility improvement to the 

class I areas in the BART analysis, the recommended BART control for SJGS is LNB, 

OFA, and a NN for NOx control and PJFF for PM control.

INTRODUCTION

A long term ammonia air monitoring study was initiated in December, 2006 at Boulder, 

Wyoming, by Shell Exploration & Production Company. The monitoring site is located 

in the Upper Green River Basin of western Wyoming southwest of the Bridger 

Wilderness, a Class I area with an IMPROVE monitoring site. This region is 

experiencing rapid development of natural gas resources with possible consequences of 

air quality and visibility impacts in the Bridger Wilderness. Only very limited short-term 

ammonia measurements were previously available for this region. Thus, the primary 

objective of this study is to characterize the local airborne nitrogen budget and, 

specifically, ammonia concentrations and concentrations of related gases and particles in 

the basin for at least one year. Gaseous and particulate samples were collected twice per 

week (integrated 3-day and 4-day samples) beginning December 15, 2006 and will 

continue through May, 2008. Samples were collected using coated annular denuders and 

stacked filters in a University Research Glassworks (URG) sampler. The Colorado State 

University Atmospheric Science Department provided laboratory-prepared sample media 

and laboratory analysis for gas and particle concentrations. Standard operating 

procedures, technical instructions, and a QAPP for instrument installation, operation and 

maintenance, field sampling, filter handling, and laboratory analyses were developed and 

submitted to Wyoming Department of Environmental Quality – Air Quality Division. 
MONITORING AND LABORATORY PROCEDURES 

Table 1 lists the instrumentation used and parameters monitored for the Boulder station 

ammonia study. Scheduled denuder and filter changes were performed twice per week, 

providing three- to four-day integrated samples for the duration of the study period. 

Ammonia concentrations and the concentrations of related gases and particles were 

measured using coated annular denuders and stacked filters in a University Research 

Glassworks (URG) sampler. The Colorado State University Atmospheric Science 

Department provided laboratory-prepared sample media and laboratory analysis for gas 

and particle concentrations. The two-channel sampler operated continuously, the air flow 

being controlled by a programmable pump with a mass flow sensor, and subsequent 

volumetric gas flow meters. The sampling method requires that metered air is drawn 

through a PM2.5 size selective cyclone inlet, then through a series of annular denuders and 

filters. The denuders are coated with an acid-based substrate to collect ammonia gas. A 

second denuder is coated with NaCl to collect gaseous nitric acid. A subsequent stack of 

two filters is utilized to collect particles. A nylon filter collects particles, and a second, 

acid-coated filter collects any ammonia volatilized from collected, semi-volatile 

ammonium nitrate particles. The nylon filter retains any nitric acid volatilized from 

particulate ammonium nitrate. Following field exposure, the denuders, filters, and field 

data logs are sent to the CSU lab for chemical extraction and analysis. Total sampler air 

volume from the data sheet is then used to calculate concentrations.

RESULTS 

Figure 1 shows a timeline of gaseous and particulate concentrations from December, 

2006 – January, 2008. Figure 2 plots the monthly mean, standard deviation, minimum, 

and maximum NH3 concentrations. NH3 concentrations are below 1 ppbv for most of the 

monitoring period, peaking in August, 2007 at 1.55 ppbv. Elevated NH3 concentrations 

here coincide with warmer summer months. A shift in ammonium nitrate equilibrium 

toward the gas phase might be responsible for some of this increase, although an increase 

in total reduced nitrogen (ammonium + ammonia) during the summer suggests that 

changes in emissions and or transport patterns are likely also important contributors.

nitrate events are interesting as all reduced nitrogen is present as particle phase 

ammonium while considerable nitric acid remains in the gas phase. Sufficient increases 

in ammonia emissions during this period could have substantially increased PM2.5

concentrations by further ammonium nitrate formation. 

Figure 3 displays a timeline of the gas/particle partitioning of the measured species for 

the same time period. Particulate sulfate (red) dominates throughout most of the year. 

Reduced nitrogen (green bars) shows an increased partitioning into the gas phase 
(ammonium to ammonia). Increased particulate nitrate in late winter is consistent with 

thermodynamic expectations: ammonium nitrate formation is favored at lower 

temperatures and higher relative humidities.

RESIDENCE TIME ANALYSIS 

Ammonia weighted back trajectories were used to identify the geographic source areas 

most likely to contribute to the highest measured ammonia days. Back trajectory analyses 

use interpolated measured or modeled meteorological fields to estimate the most likely 

central path over geographical areas that provided air to a receptor at a given time. The 

method essentially follows a parcel of air backward in hourly steps for a specified length 

of time. Back trajectories account for the impact of wind direction and wind speed on 

delivery of emissions to the receptor, but do not account for chemical transformation, 

dispersion and deposition of emissions.

Trajectories were generated using the Hybrid-Single Particle Lagrangian Integrated 

Trajectory (HYSPLIT) model developed by the National Oceanic and Atmospheric 

Administration’s (NOAA) Air Resources Laboratory (ARL). Detailed information 

regarding the trajectory model and these data sets can be found on NOAA’s Web site 

(http://www.arl.noaa.gov/ready/hysplit4.html). 

Three back trajectories were generated per day, including end times of 0400, 1200 and 

2000 MST and end heights of 100 m. Each hourly point along a 72-hour back trajectory 

paths was weighted with measured ammonia concentration corresponding to the end date 

of each trajectory. The ammonia values associated with each hourly point were then 

summed and normalized into 1/4 degree horizontal grid cells of latitude and longitude. 

Figure 4 presents a map of the ammonia weighted residence time for 2007. One path of 

influence follows the Snake River from Idaho to the Columbia River. This is a significant 
agriculture region. Another distinct path is from the South-Southwest along I-15 to 

Nevada then along the Colorado River. In addition to the major urban areas of Salt Lake 

City and Las Vegas, this pathway includes the agriculture regions of Star Valley north of 

Salt Lake City, the Wasatch front in Utah, and the Colorado River Basin.

SUMMARY 

A 15 month study in the Upper Green River Basin of Wyoming measuring ammonia and 

nitric acid gasses and ammonium, nitrate, and sulfate particles has been completed. The 

results of the study show that in the Upper Green River Basin of Wyoming 2007 

ammonia concentrations are (1) quite variable throughout the year, (2) are below or near 

detectable limits from December through late February, (3) peak in August at 1.55 ppbv, 

and (4) have a yearly mean value of 0.24 ppbv. NH3 weighted Residence time analysis 

indicates that much of the NH3 present is transported into the region from agriculture and 

urban areas to the West and Southwest.
