INTRODUCTION AND BACKGROUND

Chiquita Canyon, LLC (CCL) and the South Coast Air Quality Management District (SCAQMD) entered

into a Modified Stipulated Order for Abatement on August 19, 2021, which required the preparation

of this report. The August Order was subsequently modified on October 5, 2021 (Modified Order),

and the Modified Order maintained the requirement to prepare this report.

Among other tasks, SCS Engineers (SCS) and Blue Ridge Services Montana, Inc. (BRS) were

contracted to undertake a study and provide a report to the SCAQMD in accordance with Condition

34d of the Modified Order as stated below:

34. d. Additional study of air movement to determine whether there are any preferential

pathways for air movement outside of the Landfill, to assess the effectiveness of the orchard

fans deployed pursuant to Condition 9, and to generate recommendations for fan

configuration, including, but not limited to, the number, size, and placement of such fans.

This study shall analyze areas that CCL uses for waste disposal, including the OC Zone, and

Cell 6. The study required by this Condition 32(d) shall be documented in a report prepared

for Respondent and submitted to South Coast AQMD (attn: Larry Israel, [email protected];

Harry Moon, [email protected]; Kathryn Roberts, [email protected]; Mary Reichert,

[email protected]) on or before October 26, 2021.

This report is a follow-up to previous technical studies and reports that provided tangible information

regarding air movement at the landfill such as:

Landfill Operations Assessment Report (February 2021 Report)[1]

Air Movement Study Report (June 2021 Report)[2]

Assessment of Feasibility Report – Vegetative Barrier and Air Flow Disruptor (July

2021 Report)[3]

The February 2021 Report hypothesized that low to moderate winds with a Southerly component

could potentially move over and through low spots or “saddles” in the Western ridgeline at the

Southwestern corner of the Chiquita Canyon Landfill (CCLF). The June 2021 Report investigated this

possible preferential pathway using a series of smoke releases and concluded that air parcels were

not leaving through the identified low points in the ridgeline. Instead, air parcels rose vertically from

the source areas and became entrained in the regional winds, which carried the air parcels over the

ridgeline.

The July 2021 Report assessed the feasibility of using vegetative barriers or other airflow disruptors

along the landfill perimeter to help control potential odors. Based on the conclusions in the June

2021 Report, it became clear that because of the vertical air parcel rise, vegetative or other

perimeter barriers would not be effective. Instead, the July 2021 Report concluded that additional

mixing of the air parcels along a cross-wind horizontal plane would be more effective than vegetative

barriers in reducing the potential for odors to impact the Val Verde community. Enhanced horizontal

mixing effectively dilutes odor concentrations before they leave the CCLF.

Following the July 2021 Report, and after CCL obtained permits from the SCAQMD (with U.S.

Environmental Protection Agency approval) for engines for the Orchard Rite® fans (orchard fans or

ORFs), the CCLF began operating orchard fans as airflow disruptors in August 2021 to increase the

horizontal mixing at the Odor Control (OC) Zone and Cell 6 working faces (see Figure 1). The purpose

Additional Study of Air Movement www.scsengineers.com

of this Additional Study of Air Movement was to assess whether the orchard fans improve horizontal

mixing of air parcels at the working face.

As summarized in Section 2 of this Additional Study of Air Movement Report (October 2021 Report),

BRS completed a series of smoke releases and additional Computational Fluid Dynamics (CFD)

modeling to optimize the placement and use of the ORFs as well as the existing Tow and Blow® fans

(tow and blow fans or TBFs). Figures 2 and 3 show photographs of the fans at the working face.

In order to assess the effectiveness of the ORFs and to evaluate whether there are other preferential

pathways for air parcel movement toward Val Verde, SCS completed a series of smoke releases at

the OC Zone and Cell 6 working faces during unfavorable wind conditions, which are thought to have

the potential to carry surface air from the point of release into the Val Verde community. The results

from these smoke releases are summarized in Section 3 of this October 2021 Report.

FAN OPTIMIZATION

BRS performed the fan optimization portion of this study. BRS staff were onsite at CCLF August 30

through September 2, 2021. BRS performed smoke studies on August 31, September 1, and

September 2, 2021. The following section presents a summary of the testing conditions,

methodology, observations, data collected, updated modeling, and recommendations for fan

numbers and placements around the working face area.

PURPOSE

The objective of the fan optimization study was to assess the effectiveness of the three ORFs

currently deployed at CCLF, and to generate recommendations for fan configuration, including the

number, size, and placement of orchard fans. This analysis was conducted using drone- and ground-

based video collection of smoke movement, handheld anemometer (wind speed) data collection,

and observation of wind influence in and around the working face. The data and observations were

used to generate new CFD models, with software adjustments made to ensure the modeling

accurately represents field data. The prior CFD models focused on the air mixing potential of the

TBFs with some additional CFD modelling of the ORFs, but no field testing verification because the

ORFs had not been permitted at the time of that prior study. The new CFD models and the smoke

tests performed for this fan optimization study provided a more accurate understanding of the

influence of both types of fans on air parcels at the working face. The results of this study, as

detailed in Section 2.3, include updated recommendations for the number of fans, fan configuration,

and the maximum working face surface area that the current fans being used at CCLF can effectively

cover.

The CFD modeling performed for this study sought the most effective fan configuration that achieves

sustained air velocities at the working face of over 5 miles per hour (mph) (2.24 m/s) which

improves horizontal mixing. This threshold was established based on the February 2021 Report[1]

and related air movement study. Air velocities over this threshold result in adequate airflow

disruption causing air parcels to be dispersed near the working face and potential odors to be

mitigated.

METHODOLOGY

All testing was performed in the morning hours, typically between the hours of 6:00 am and 10:00

am, and always during unfavorable wind conditions, which were identified in the February 2021

Landfill Operations Assessment Report[1] and defined in the Modified Order as winds being between

0 and 5 mph with a Southerly component. Forecasts for each test day were checked the night

before to ensure that winds would be between 0 and 5 mph and would typically be from the South.

Prior to commencing each day’s testing, BRS staff met with CCLF staff to coordinate activities, to

ensure the safety of all personnel and that the study did not interfere with CCLF waste placement.

Smoke release locations were identified in each cell. Wind measurements and other weather

observations were taken prior to the start of each test period with random, additional wind

measurements taken during testing.

Additional Study of Air Movement www.scsengineers.com

A baseline test was performed by releasing smoke around the working face but outside of the

influence of the fans to establish a visual reference for natural smoke movement in the prevailing

wind (“Baseline” test). Testing then occurred near the working face within the zone of fan influence

(“Fan Effectiveness” test). This allowed us to visually determine the effectiveness of various fan

configurations by comparing to the Baseline test. Criteria for the Fan Effectiveness testing included:

Baseline: smoke placed as far from the fans as allowable by topography but not farther than

600 feet horizontally and 50 feet vertically from working face.

Fan Effectiveness: smoke placed on the edges of the exposed waste when operationally safe

to do so. If waste placement activities posed a safety risk, then the smoke device was

placed downwind of the working face as close to the exposed waste as possible.

A minimum of three smoke release points were utilized for both the Baseline and Fan

Effectiveness smoke tests.

For each smoke test, video footage was taken via drone- and ground-based cameras.

General Site Conditions

During the three days of testing, CCLF was operating two active working faces: one within Cell 6 and

the other in a sliver fill within the OC Zone (see Figure 1).

Test Conditions

The weather was overcast with high clouds all three days with moderate temperatures staying in the

mid-60’s for the duration of the testing. The humidity was slightly higher than normal, but no

precipitation occurred during testing. Though these weather conditions were atypical for the region

during the test period, they did not adversely impact the testing or conclusions about the

effectiveness of the fans.

Testing in Cell 6

Operations were in the far Eastern side of Cell 6 with active waste disposal occurring at the

Northeast corner of the working face. Fans were located along the Northern and Western perimeters

of the working face as shown in Figure 4 and in accordance with Standard Operating Procedure

(SOP) 2.

Figure 6. Cell 6 Fan Effectiveness Test Smoke Release Points and Observations

Though testing on each day resulted in similar findings, it should be noted that based on

observations made on Day 1, minor changes to the fan locations and orientations were made for

testing on Days 2 and 3. These changes included moving a TBF on the upper deck and the ORF on

the lower deck closer to the working face and orienting the ORFs and TBFs on the upper deck in a

single line to ensure airflows were directed over the working face.

Testing in the OC Zone

Fill operations in the OC Zone were occurring on a sliver fill along the East slope of the landfill. Due

to the narrow lift and side slopes, only two fans were in use at the time of testing as shown in Figure

7: a TBF on a bench approximately 30 feet above the working face and an ORF on a bench at the

same elevation as the tipping area.

Wind conditions were measured in four locations around the working face and all velocities recorded

were within the 0 to 5 mph range though directions varied depending on location. This variability in

wind direction was likely the result of the complex topography around the fill area, which included

steep slopes that channel the airflow. Though the wind directions were not consistent, this did not

impact the testing or the observed results due to the velocities being within the range defined as

unfavorable winds given the primary purpose of this test was to evaluate the effectiveness of the

fans at accelerating wind speeds and subsequently improving horizontal mixing at the working face.

Figures 8 and 9 show the behavior of the smoke released in the Baseline and Fan Effectiveness

tests at the sliver fill in the OC Zone.

Figure 9. OC Zone Fan Effectiveness Test Smoke Release Points and Observations

Direct observation and video review indicated that the ORF provided the greatest horizontal mixing of

smoke due, in part, to it being closest to the elevation of the working face. The TBF provided

minimal impact due, in part, to its location on a bench approximately 55 feet (vertically) above the

working face. While the single ORF provided accelerated air speeds and mixing, the reach of this

positive impact was limited to no more than 20 feet on either the left or right of its flow path. This

information was used to revise the CFD modeling as detailed in Section 2.3 of this report.

Smoke Test Conclusions

After three days of testing, it was evident that the ORFs achieved the greatest horizontal mixing and

diffusion of smoke when compared to the TBFs. This is because the ORFs produce a larger diameter

air column and create a larger zone of influence for mixing the air. This zone of influence is the

result of the Bernoulli Principle, where high velocity airflow creates a low-pressure zone pulling on

the surrounding air and accelerating it as it enters the primary flow path (see Figure 10). By

accelerating the air, a higher level of mixing occurs when compared to what is achieved by natural

wind speeds during unfavorable wind conditions.

This phenomenon occurs with both the ORFs and the TBFs, but because the effect is dependent on

airflow velocity and the size of the air column, the ORFs are more effective. Although both fans

create an initial velocity of approximately 50 mph (22.4 m/s), the ORFs mix at least 344% more air

than the TBFs.

Figure 10. Bernoulli Principle: Fan Air Column Influence

Based on the field observations of the smoke studies, we were able to refine the CFD modeling used

in the development of SOP 2 and the July 2021 Report[3] and perform new modeling to optimize the

number, type, and placement of fans around the working face. The following section covers this

updated modeling.

REVISED CFD MODELING

The goal of the updated CFD modeling was to generate fan configurations that will mix the air at and

around the working face to above 5 mph (2.24 m/s), which is the minimum threshold for diffusing

any surface emissions into the surrounding air, resulting in reduced potential odor concentrations.

In order to do so, we used the original CFD modeling used to prepare SOP 2 and the July 2021

Report[3] and incorporated our observations from the fan optimization analysis (see Section 2.2).

Extent of ORF and TBF Influence

As with the prior CFD modeling, the revised CFD modeling looked at the ability for individual fan types

to accelerate air beyond the 5 mph (2.24 m/s) threshold and how far that ability reached. This

progressed to modeling multiple fans of the same type and then different configurations of both the

TBFs and ORFs. The first series of models used for the July 2021 Report and to develop SOP 2 were

based on a flat surface, whereas the final modeling for this October 2021 Report incorporated the

20-foot vertical lift, which is typical for the operating conditions at CCLF.

Figure 11 shows the concept of the fan air column and how far to each side the fan influences the

air.

Additional Study of Air Movement www.scsengineers.com

12

Figure 11. Plan View: Diagram of Typical Fan Air Column

Figure 12 shows CFD modeling results for the effect of a single TBF and a single ORF and the

maximum length and width of the fans’ zone of influence. It is important to note that the effective

range (shown in meters) of these two fan types differs considerably. The ORFs are clearly able to

influence air movement across a much larger range than the TBFs. Therefore, the ORFs are a much

more effective tool for reducing odor concentrations.

Figure 13 shows cross sections along each fan’s centerline and the air velocity within the column of

air mixed by a TBF and ORF. The cross sections were taken at 50 feet (15 meters), 130 feet (40

meters), and 295 feet (90 meters) from the fans. Here again, we see the difference between these

two types of fans. The TBFs provide some air movement that is important to fill the gaps between

the ORFs. However, the ORFs shoulder the responsibility of creating the airflow needed for odor

disruption.

Figure 13. Section View: Extent of ORFs and TBFs with Air Velocity 5+ mph (2.24 m/s)

Figure 14 shows the graphs detailing the fan velocities for both TBFs and ORFs along the centerline.

Data was measured in the model at both 3 feet and 20 feet above the ground for the ORFS, and 3

feet and 25 feet for the TBFs, to verify that the air velocity was consistently above the 5 mph

threshold for the entire working face.

By measuring the wind velocity in the CFD models at different elevations above ground level, we

determined the allowable offset distances for each fan type from the working face. To verify the

accuracy of the CFD modeling, these values were compared to field measured velocities, which

showed that the modeling was within 7% accuracy with the velocities measured in the field. Given

the variability of real-world conditions including terrain and other factors, this is an acceptable level

of variance.

Optimizing Fan Configuration

Once the zone of influence for each fan type (ORF and TBF) was determined, modeling was

performed to evaluate what combinations of fans would be most effective. Key parameters included

fan placement, spacing between fans, alignment, height, distance, and orientation relative to the

working face.

To ensure that the fans would mix air over the entire working face, a zone of 180 feet by 180 feet

was typically assessed as it is approximately 75% of the maximum working face surface area

permitted by CCL’s Conditional Use Permit (CUP). Zones of 150 feet squared (~52% of the maximum

working face surface area) were also modeled to reflect a smaller individual working face size.

First we considered whether any changes were necessary to previous instructions regarding the

TBFs. After performing the additional modeling in conjunction with the smoke testing, we identified

some needed changes to the original TBF offset distances and spacing specified in SOP 2. Those

changes include:

When TBFs are used without ORFs, they should be no less than 50 feet and no more than

100 feet from the working face.

The lateral spacing between the TBFs should be no less than 25 feet and no greater than 35

feet between the centerlines of the fans.

Figure 15. Plan View: 2 ORFs and 1 TBF

Figure 16. Evaluation of ORF Horizontal Influence at 65-foot Spacing

Next, we considered whether any changes were needed with respect to our recommendations

regarding placement of ORFs. Our ORF modeling also indicated that when ORFs were placed 50 to

75 feet apart, the combined airflow of the ORFs was improved (Figure 16). This synergy, where the

combined effect is greater than the sum what would be expected for each of the individual fans, is

an important concept and is apparent in most cases where multiple fans are utilized.

In this example, when three ORFs were placed in a row with 50 to 75 feet spacing between them, the

combined airflow resulted in effective coverage of 180 feet by 180 feet (75% of the maximum

working face size permitted by CCL’s CUP), where the air velocity consistently exceeded 5 mph. By

having fans isolated or too far apart from other fans, the resulting zone of influence is dramatically

reduced as can be seen by comparing the single ORF fan shown in Figure 12 and the area of

influence shown above when multiple fans are used.

It is also important to note that ORFs work optimally when they are placed between 150 feet and

350 feet from the working face.

Additional Study of Air Movement www.scsengineers.com

17

Finally, we considered whether any changes were needed with respect to our prior recommendations

regarding use of the ORFs in combination with the TBFs. When using a combination of TBFs and

ORFs, we found that staggering them – based on their optimum distance from the working face –

provided the same synergistic effect described above. Figure 15, however, shows an example of

how using only two ORFs and one TBF does not provide adequate coverage for a working face that is

75% of the maximum size allowed by the CUP. The colored areas are where the fans have

accelerated the air in the model to beyond the 5 mph (2.24 m/s) threshold. By increasing the

number of fans to 3 ORFs and 5 TBFs, full coverage is achievable for a working face that is 75% of

the maximum size allowed by the CUP (Figure 19). The area influenced is dependent on the number

and type of fans. The more fans, the more area that can be covered.

Effect of Topography on Fans

After considering optimal fan placement on a flat plane, we incorporated topography into our

analysis. We were able to make two primary conclusions regarding the effect of topography on the

effectiveness of the ORFs and TBFs. First, we found that fans placed on the lift above the working

face, where the fans would blow over and down toward the working face, will not provide a wind

velocity of 5 mph or greater at the working face. Instead, as the fans blow over the edge, a small but

consistent eddy is created, where airflow stagnates at less than 5 mph as illustrated in Figure 17.

The variables that influence this effect include the height of the slope, the steepness of the slope,

and the velocity of the fan air column when it reaches the slope. Figure 18 shows what occurs when

fans are placed at a higher elevation and are configured to blow air over a downward slope.

Approximately 20% of the working face did not have airflows above the 5 mph (2.24 m/s) threshold.

Even with additional fans, this area of uninfluenced air remained due to the slope of the lift.

Figure 17. Slope-Caused Zones of Slower Air With Fans Only on Upper Lift

Second, our modeling showed that placing the more powerful ORFs on a lower lift deck so that they

blow up slope to the next higher lift and placing the less powerful TBFs on the upper lift is able to

provide full and effective coverage (airflow at or above 5 mph) across the entire working face.

In summary, the utilization of the different fan types across various topographies and cell

dimensions requires thoughtful application. There is no “one-size-fits-all,” but we have developed a

range of criteria that CCLF can employ to ensure that the TBFs and ORFs provide effective coverage

under different operating scenarios. One of those configurations is depicted in Figure 19.

Additional Study of Air Movement www.scsengineers.com

18

Figure 18. Working Face Velocities with ORFs and TBFs on Upper Lift

Slopes in the working face should be addressed by dividing the fans between the top of the working

face and the bottom, with the more powerful ORFs on the bottom blowing across the working face.

As Figure 19 shows, using this configuration, all of the working face surface air exceeds the 5 mph

(2.24 m/s) velocity threshold for a working face that is 75% of the maximum size allowed by the CUP.

An additional ORF – once permitted – on the lower deck will easily achieve full coverage for 100% of

the working face size allowed by the CUP.

Conclusions of CFD Modeling

After conducting a series of CFD modeling, and correlating much of it with field testing, we

determined the distances between the fans and from the working face at which the ORFs and TBFs

can provide an air velocity of 5 mph or greater. As shown in Table 1, those distances are:

Table 1. Fan Centerline Spacing and Offset from Working Face Distances

Fan Type Spacing Between

Similar Fan Type

Spacing Between

Different Fan Type

Distance from Working

Face

TBF 25-35 Feet 50 Feet 50-75 Feet

ORF 50-75 Feet 50 Feet 150-350 Feet

Based on these findings, a single fan should be available for every 50 feet of the downwind sides of

the working face, using either all ORFs or a combination of ORFs and TBFs. For example, if the

working face is 200 x 200 feet in size (91% of the maximum working face surface area), then the

total downwind length would be 400 feet, thus suggesting either 8 ORFs or a combination of ORFs

and TBFs (8 total). It is important to note that this is a rough guideline based on an ideal model.

Due to real-world constraints like topography, the number of fans needed may vary. For example,

while CCLF currently has the minimum number of fans required for effective mixing based on a

hypothetical working face size of 91% of the maximum allowed by the CUP, when topography was

added to the model (see Figure 19), we noted that CCLF has the minimum number of fans to cover a

working face size of 75% of the maximum allowed by the CUP. The addition of more ORFs will

ensure full coverage of the working face (100% of the maximum allowed by the CUP) even when

outside factors are taken into account, and will also allow for ORFs being shut down for

maintenance. With a total of 9 ORFs (the 3 CCLF has now plus the 6 for which applications are

pending), CCLF will have more than enough fans to provide effective mixing at 100% of the working

face size allowed by the CUP. Further, the exact placement of fans will be dependent on numerous

factors, including topography, space constraints, and operational and safety needs (i.e., we are not

recommending precisely one fan every 50 feet).

ADDITIONAL AIR MOVEMENT STUDY

After BRS optimized the fan configuration, SCS performed the additional air movement portion of this

study to evaluate fan effectiveness and air parcel movement in both Cell 6 and the OC Zone.

Additional smoke releases were conducted on September 17, September 23, September 24, and

September 25, 2021 and were photographed from various ground-based vantage points in

conjunction with aerial drones flying at elevated vantage positions relative to each smoke plume.

This visual study provided documentation of how well the fans served to dilute surface releases and

provided insight on how air parcels are transported from the working faces and into the surrounding

area.

METHODOLOGY

Meteorological forecasting was first used to predict dates and times when conditions would be

suitable for testing. Winds conditions considered suitable for testing were based on the February

2021 Report[1], which identified certain conditions as correlating with verified odor complaints in the

community of Val Verde. These “unfavorable wind conditions” are reflected in Condition 3 of the

Modified Order, which identified winds with a Southerly component (including Southeast, Southwest,

and East-Southeast winds) with low to moderate wind speeds (0-5 mph) as “unfavorable wind

conditions” more likely to result in air movement off-site toward Val Verde. For this study, September

17, September 23, September 24, and September 25, 2021 were selected for testing based on a

review of meteorological forecasts by SCS’s meteorologist. During each day of testing, up to five

separate tests were conducted (i.e., two working faces with two to three tests per working face,

based on accessibility). For each test:

Smoke was released from two to three on-site locations at each working face for

approximately 15 minutes using three to five smoke candles per release point.

Release locations were selected based on field conditions (e.g., fan locations, tipping/

unloading areas, heavy equipment activity, topography, safety needs) so that airflow could be

observed from the working face (e.g., between the fans and the working face, along the sides

of the working face, and/or from the opposite side of the working face relative to the fan

locations).

Videos and photographs were taken from various vantage points using two drones, three Go-

Pro cameras, and two cell phones. Relevant example photographs are provided in this

report, including a description of the vantage point from where the photo was taken and the

direction the photographer is facing. These vantage points can be referenced to the maps of

smoke test release points.

Specific release points for each day of testing are detailed below.

A total of 18 tests were conducted over the four days selected, each with multiple release points.

Following the four days of testing, conclusions were made based on analysis of the imagery collected

and the corresponding meteorological data. In all, a total of about 750 gigabytes of smoke plume

movement imagery was collected with this study. Only portions of that imagery are presented in this

report due to size. The smoke test analysis that is part of this October 2021 Report was conducted

after the ORF placement and orientation had been optimized using the configurations as detailed in

Section 2.0. Note that because CCLF was using two different working faces, Cell 6 and the sliver fill

of the OC Zone, there were never three ORFs in use at one working face during the smoke testing.

Smoke Test Meteorology

Meteorology varied by test day and, to some extent, by release point. This was consistent with what

was observed during the meteorological study completed as part of the February 2021 Report[1] as

well as conditions generally observed on-site during the testing period. Variations were due in part to

the complex terrain within and surrounding the CCLF as shown in Figure 32 as well as due to normal

changes in regional winds in the area. Figures 33 to 50 use proportionally scaled/rotated arrows to

illustrate how on-site and regional wind speed (WS) and wind direction (WD) varied during the smoke

tests at six meteorological (MET) monitoring stations (MS-01 to MS-06)[4]. The green arrows

represent on-site wind conditions while the orange arrows represent regional winds.

These figures demonstrate how on-site and regional winds can differ at the same time of day and

how this can affect air movement within the CCLF and off-site. Figures 51 to 58 illustrate how the

projected regional winds varied on each smoke test day[5]. See Attachment A (wind roses) and

Attachment B (table of wind conditions) for the 10-minute wind data measured at the six monitoring

stations.

Testing was focused on the unfavorable 0 to 5 mph winds from the South, Southeast, East-

Southeast (see Section 3.1 for details). These unfavorable wind conditions were primarily observed

in the morning hours until winds from the West developed in the afternoon. Testing also evaluated

other winds if they occurred during the testing period, although such winds have a minimal potential

to cause off-site impacts to the Northwest (in the direction of Val Verde) based on the conclusion of

February 2021 Report[1].

ANALYSIS AND CONCLUSIONS

Several conclusions can be drawn from the September 2021 series of smoke tests that were

conducted while the ORFs were operating at CCLF. In all cases, the ORFs were positioned in a line at

one end of the working face, blowing against the on-site winds, and positioned to blow over the

entirety of the working face (see Section 2.0 for more details). The ORFs were split between the two

working faces, such that no more than two ORFs were present at a given working face. These

conclusions are as follows:

1. Consistent with BRS’s findings, the ORFs are effective in dispersing localized surface

emissions as exemplified by the various smoke releases conducted in and around the

working faces at the OC Zone and Cell 6. We believe that the analysis of smoke plumes

provides a good representation of how odor plumes behave.

2. Consistent with BRS’s findings, field observations and smoke studies clearly revealed that

when the fans are oriented both downwind and crosswind (i.e., perpendicular) to the surface

wind, the smoke plumes are better dispersed.

3. The fans’ influence does not always reach the farthest aspect of the working faces, especially

when the working face extends into lower elevations such as in the sliver fill area of the OC

Zone. In such instances, additional fan capacity that covers the lower areas would be

beneficial.

4. In all cases, smoke plumes after dilution by the operating fans were observed to eventually

mix vertically and become entrained into the regional airflow, consistent with the conclusions

of the previous air movement study. No preferential pathways were identified for air

movement from the OC Zone and Cell 6 outside of the CCLF. The only difference noted

between the OC Zone and Cell 6 smoke tests is that smoke from the OC Zone tended to

move toward the Northwestern ridgeline while smoke from Cell 6 tended to move toward the

Western ridgeline, once entrained in the regional airflow.

The sections below provide expanded discussion of each of the above stated conclusions.

Conclusion 1

The orchard fans are effective in dispersing localized surface emissions.

From the hours of video imagery and personal observations, it is clear that the fans utilized at the

CCLF provide added dispersion of airborne pollutants from locally emitting sources. The use of

smoke plumes visually demonstrated this outcome from fan usage. While we do not have a

quantitative measurement of the amount of added dilution from fan usages, it appeared that from a

visual observation the concentration of the smoke was diluted by a factor of at least three through

use of the fans. This would imply that surface emissions would be reduced similarly.

Figures 59 to 61 are example images recorded by drones of smoke plumes generated at the OC

Zone and Cell 6. These images illustrate that the visual density of the smoke plume that is

influenced by fan operation is much lower than that of a smoke plume that is not influenced by fan

operation. Based on inspection of the videos from which these images were derived, it took at least

three times longer for the smoke plume not influenced by the fans to disperse to a point that it was

hardly discernable. Please note that smoke releases outside of the fan influence were used for

baseline conditions, and all smoke releases were identical in strength and duration.

Conclusion 2

Smoke plumes are better dispersed when the fans are oriented both downwind and crosswind to the

on-site surface wind.

Our field observations and video evidence suggest that the fans are most effective when they are

directed such that their influence has a component that is perpendicular to the on-site surface wind

direction (e.g., crosswind) at the working face (see Section 3.2.5 for a summary of wind conditions

during the testing). This crosswind fan direction would be in addition to fans placed directly into or

downwind of the on-site surface wind direction.

This is consistent with BRS’s findings and conclusions, and this placement would serve to improve

horizontal mixing of any surface emissions coming from the working face, thus distributing the mass

of air parcels over a larger area. Pointing the fans directly into the wind does promote dilution of

emissions; however, this orientation tends to spread the plume both vertically and horizontally.

Since mixing is limited in the vertical direction due to atmospheric stability constraints, smoke plume

dilution with fans only placed directly against the wind direction has some limitations. Wherever

possible based on site conditions, fans should be oriented so that air movement is both directly

against (downwind) and crosswind of the surface wind flow, which would maximize both horizontal

and vertical mixing. See Figures 62 to 63 for examples images of the smoke plume mixing with the

fans operating.

Conclusion 3

The fans’ influence does not always reach the farthest aspect of the working faces.

The numerous smoke tests conducted revealed that the fans can have a limited zone of influence

under certain conditions. When used in the sliver fill area of the OC Zone, the fans were unable to

influence smoke plumes at the most distant extent of the working face. This was most evident when

parts of the working face were at a significantly lower elevation than the fans. The strength of the

on-site surface winds also had an influence on the zone of influence of the fans. Under higher winds,

the influence of the fans is diminished, especially when the winds are blowing directly at the fans.

However, these higher winds are generally not a concern for off-site odor impacts as they provide for

substantial mixing on their own and do not represent the unfavorable wind conditions that are of

concern for CCLF. Additional fan capacity, as well as crosswind orientation of the fans when feasible,

will allow fan influence to reach to the farthest area of the working face. See Figures 64 to 67 for

example images of smoke plumes not influenced by the fans, which were based on smoke releases

conducted outside of the fan influence to assess baseline conditions.

Conclusion 4

After being diluted by the fans, smoke plumes were observed to eventually mix vertically and become

entrained into the regional airflow.

In all tests that were conducted under this study, diluted smoke plumes eventually mixed vertically

and then were entrained into the regional airflow. This vertical mixing, as witnessed in all of the

previous testing conducted by SCS, is very robust. In general, once the diluted smoke plumes rose to

about 200 to 400 feet above ground level, the entrainment process into the regional winds was

evident. Smoke studies conducted earlier in May 2021 and documented in the June 2021 Air

Movement Study Report[2] revealed that the saddles (low points) in the Western ridgeline do not

drain airflow outside of the CCLF. We observed that the smoke plume rise continued above the

elevation of the saddles, and mixing occurred at a higher elevation above the level of the saddles.

We did not observe any smoke plumes leaving directly through the saddles during the May or

September 2021 smoke studies. See Figures 68 to 69 for example images of smoke plume vertical

mixing.

Based on this Additional Air Movement Study, no preferential pathways for air movement from the

OC Zone or Cell 6 and outside CCLF were identified. The smoke followed the previously identified

pathway of vertical air parcel rise within the cell, resulting in entrainment in the regional wind flow

above the landfill ridgelines. The only difference noted between the OC Zone and Cell 6 is that

smoke from the OC Zone tended to move toward the Northwestern ridgeline while smoke from Cell 6

tended to move toward the Western ridgeline, once entrained in the regional airflow.

OVERALL RECOMMENDATIONS

BRS RECOMMENDATIONS

Based on the smoke study and CFD modeling, it is recommended that SOP 2’s Fans Section criteria

be revised and added to as follows, with items not listed here being left as originally approved.

Fan placement:

The fans should be placed downwind of the working face with their primary directional flow

blowing into and/or perpendicular to the wind and toward the working face.

When operationally feasible and safe, Tow & Blow® fans should be placed no closer than 50

feet and no farther than 75 feet from the edge of the working face.

When operationally feasible and safe, Orchard Rite® fans should be placed no closer than

150 feet and no farther than 350 feet from the edge of the working face.

When operationally feasible and safe, Orchard Rite® fans should be placed on the deck of

the lower lift so their airflow is blowing up the working face. Additional Orchard Rite® and

Tow & Blow® fans can be placed on the upper deck of the current lift with airflow directed

across the working face.

Horizontal spacing: The horizontal spacing in between the fan centerlines should be as follows:

Spacing between Tow & Blow® fans should be between 25 and 35 feet

Spacing between Orchard Rite® fans should be between 50 and 75 feet.

Spacing between Tow & Blow® fans and Orchard Rite® fans when utilized together is to be

approximately 50 feet.

Number of fans: The total number of fans utilized at the working face will be dependent on the size

of the working face, with approximately one fan for every 50 feet of distance along the downwind

perimeter of the working face. It is important to note that this is a rough guideline based on an ideal

model. The actual spacing and placement of the fans will be dependent on the fan type, topography,

and other operational considerations while adhering roughly to the distances specified in Table 1

(i.e., we are not recommending precisely one fan every 50 feet). CCLF currently has the minimum

number of fans to cover a working face size of 75% of the maximum allowed by the CUP. The

addition of more ORFs will ensure full coverage of the working face (100% of the maximum size

allowed by the CUP) even when outside factors are taken into account, and will also allow for ORFs

being shut down for maintenance. With a total of 9 ORFs (the 3 CCLF has now plus the 6 for which

applications are pending), CCLF will have more than enough fans to provide effective mixing at 100%

of the working face size allowed by the CUP.

68

SCS RECOMMENDATIONS

Based on the results of the additional air movement study and the fan layouts during the testing (i.e.,

a maximum of two ORFs at each working face at any time with operations both in the OC Zone and

Cell 6), additional mixing would appear to be necessary to control surface emissions across the

entire working face and to ensure that the maximum mixing possible occurs before the air parcels

move vertically above the CCLF. This can be accomplished through the use of more than two ORFs

at a single working face.

To this end, SCS recommends that additional ORFs, in conjunction with the TBFs, litter fences, and

neutralizer application, be employed to better control potential odors. The ORFs should be oriented

so that they blow directly into the on-site surface winds from a downwind location, and whenever

feasible, at least one fan should blow crosswind to the on-site surface airflow. BRS’s

recommendations for the number and placement of fans should be implemented.

SCS has submitted, on behalf of CCLF, applications for engine permits for six additional ORFs. It is

unclear whether all six additional fans (for a total of nine fans) will be necessary; however, with these

additional fans on-site, CCLF will have adequate additional flexibility to optimize the placement and

orientation of the fans as well as to maximize the airflow and ground level mixing.
