No. 15cv1394 GPC (BGS)

Plaintiffs, ORDER GRANTING IN PART AND

DENYING IN PART PLAINTIFFS’

MOTION FOR SANCTIONS AND

PRESERVATION

[ECF No. 31.]

v.

AMETEK, INC., a Delaware corporation;

SENIOR OPERATIONS, LLC, a limited

liability company; and DOES 1 through

100, inclusive,

Defendants.

I. Introduction

On November 20, 2015, the Honorable Gonzalo P. Curiel, referred Plaintiffs’ 

Motion for Sanctions and Preservation to the Honorable Bernard G. Skomal, United State

Magistrate Judge, for decision. [ECF Nos. 45-46.] In their motion, Plaintiffs seek

sanctions for Defendant Ametek’s failure to collect initial emissions results from six sub

slab depressurization (“SSD”) systems1

 at the Magnolia Elementary School. [ECF No.

31-1 at 3:13-16.] Plaintiffs claim they were never notified of the date the SSD systems

would be activated and because Ametek did not collect emission samples or install

sample ports in the SSD system, initial emissions results that could have revealed the

conditions at Magnolia Elementary prior to remediation can never be recovered. Id. at

4:19-5:3. The sanction requested by Plaintiffs is an adverse inference jury instruction. 

Plaintiffs also seek a preservation order requiring Ametek to provide Plaintiffs’ counsel

with notice of remediation efforts. Ametek filed an opposition to Plaintiffs’ motion on

October 30, 2015. [ECF No. 40.] Plaintiffs filed a reply on November 13, 2015. [ECF

No. 42.]

After careful consideration of the parties’ briefs, exhibits and declarations, the

Court GRANTS IN PART and DENIES IN PART Plaintiffs’ motion for the reasons

explained herein. 

II. Factual Background

This case arises out of the dumping by Ametek and its predecessors of toxic waste

into a temporary waste storage tank on property adjacent to Magnolia Elementary School. 

[ECF No. 21.] In their First Amended Complaint, Plaintiffs allege Defendants discharge

of waste on the Ametek property caused waste plumes to concentrate beneath Magnolia

Elementary and that various chemicals contained in those waste plumes have been found

by federal agencies to have toxic health effects. Id. at 8, 20-22. 

The impact to soil and groundwater at Magnolia Elementary and other areas

adjacent to the former Ametek facility has been assessed since 1994. See Declaration of

Ametek’s expert, Truong Mai, ECF No. 40-1 at ¶ 8. These investigation activities at

Magnolia Elementary are overseen by the California Department of Toxic Substance

Control - School Property Evaluation and Cleanup Division. Samples of soil vapor,

groundwater, outdoor air and indoor air have been collected from sampling locations at

Magnolia Elementary over the course of the last 20 years. Id. at ¶ 8-9. 

Ametek recently agreed to install sub slab depressurization (“SSD”) units at four of

the permanent classrooms at Magnolia Elementary and air exhaust system (“AES”) units

at two of the mobile classrooms at Magnolia Elementary as a pilot test in order to gauge

the efficacy of SSD and AES units on vapor intrusion into classrooms. Id. at ¶ 14. The

California Department of Toxic Substance Control also oversees the pilot tests. Id. 

Specifically, the SSD units are designed to remove vapors from beneath the

foundation of the permanent classrooms. Id. at ¶ 17. The AES units are designed to

exhaust air in the space between the floor of the mobile classroom and ground. Id. at ¶

17. Measurements of pressure and vacuum data are being collected during the pilot

testing because the SSD and AES units were primarily designed to remove air from

underneath classrooms effectively. Id. at ¶ 18. Chemical data has not been recorded

through the SSD and AES units. Id. However, a sampling and monitoring port were

installed beneath the pipes of the SSD and AES units which could be used to collect

samples for chemical analysis. Id. at ¶ 19. 

On June 1, 2015, three days after Plaintiffs filed their state court complaint,2

Magnolia Elementary School was closed by the Board of Governors of the Cajon Valley

Union School District for the 2015-2016 school year because of the risk of toxic vapor

intrusion into the classrooms there. [ECF No. 21 at 1.]

On June 25, 2015, Plaintiffs’ counsel sent a preservation letter via email to counsel

for Ametek,3

 counsel for Senior Operations4 and counsel for the Cajon Valley Union

School District5

 requesting “current property conditions” be maintained at Magnolia

Elementary School until a meet-and-confer regarding testing and inspection could be

completed. [ECF No. 31-4, Exh. A at 2.]

On August 3, 2015, Plaintiffs’ counsel sent a second preservation letter via email

to counsel requesting no additional or new remediation work be done at a different

location called the “Ketema/Ametek property” without notification and an opportunity to

On August 18, 2015, Ametek’s counsel responded to both of Plaintiffs’

preservation emails by noting that access to the “Magnolia site” needed to be coordinated

with the School District’s counsel and access to the “Ketema site” needed to be arranged

with the counsel for co-defendant Senior Operations, LLC. Id., Exh. C at 7. 

On August 26, 2015, Plaintiffs’ counsel alerted opposing counsel that the Cajon

Valley School District was making Magnolia Elementary available for a site inspection

on September 1, 2015. Plaintiffs’ counsel also wrote a further email on August 27, 2015

indicating that after the visual site inspection on September 1, 2015, he was “planning a

follow up to take samples.” Id., Exh D. at 12-13. 

On September 1, 2015, a site inspection was conducted at Magnolia Elementary,

which was attended by Plaintiffs’ counsel - John Fiske; Plaintiffs’ expert - Anthony

Brown; Ametek’s counsel - Edward Walton; and Ametek’s expert - Truong Mai, as well

as representatives of the Cajon Valley School District and environmental consultants for

the project. ECF No 40-2 at ¶ 3; ECF No. 40-1 at ¶ 15; ECF No. 42-2 at ¶2; ECF No. 42-

1 at ¶ 6. 

Ametek’s expert, Truong Mai, told those assembled at the September 1, 2015 site

inspection “that the SSD and AES units would be turned on immediately after completion

of construction in mid-September.” Mai Decl. , ECF No. 40-1 at ¶ 15. 

On September 10, 2015, Plaintiffs’ counsel sent an email to the Cajon Valley

Union School District’s counsel requesting “to meet and confer as soon as possible and

before any remediation occurs to discuss next steps.” ECF 31-4, Exh. E at 19. Ametek’s

counsel was copied on this email. Id.

On September 11, 2015, Ametek’s counsel notified Plaintiff’s counsel via email

that Ametek’s lead counsel, attorney Ed Walton, was out of the country and unavailable

to meet and confer until approximately September 15, 2015. Id., Exh. F at 20-21.

Also, on September 11, 2015, Senior Operation’s counsel replied to Plaintiff’s

counsel as well as counsel for Ametek and the Cajon Valley Union School District that he

preferred to have a conference when Mr. Walton returned to town. Id., Exh. G at 23. 

Counsel for the Cajon Valley Union School District also replied to Plaintiff’s

counsel, counsel for Ametek and Senior Operations’ counsel on September 11, 2015,

stating that: “The District wants to cooperate with these efforts, but does not want this

process to delay installation of engineering controls.” Id., Exh. H at 25.

On September 14, 2015, Ametek’s counsel advised that Mr. Walton would be “not

be back in the office and available for a conference call until Wednesday [September 16,

2015].” Id., Exh. H at 25.

The SSD and AES units were activated on the afternoon of September 16, 2015. 

Mai Decl. , ECF No. 40-1 at ¶ 16.

On September 22, 2015, Plaintiffs’ counsel sent an email to Ametek’s counsel,

Senior Operation’s counsel and counsel for the Cajon Valley Union School District 

announcing, “we and our experts would like to be present when the sub slab

depressurization is ‘turned on’. Prior to the system’s commencement, we would like to

install sample ports on the exhaust.” ECF No. 31-4, Exh. I at 28.

On September 24, 2015, Plaintiffs’ counsel learned that the SSD and AES units

had been activated. ECF No. 31-1 at 6:17-19; ECF No. 40-3 at Exh. E.

III. Parties’ Arguments

A. Plaintiffs Request An Adverse Inference Jury Instruction Due To

Ametek’s Spoliation of Vapor Emissions Data And A Preservation Order To

Prevent Further Loss Of Evidence. 

Plaintiffs argue sanctions are warranted because initial emission readings from the

six SSD and AES systems, which were never collected, will never be known. Plaintiffs

contend initial emissions data would have been the best evidence of actual vapor

conditions underneath Magnolia Elementary prior to depressurization. Plaintiffs

underscore the fact that they were never notified of the actual date the SSD system would

be turned on despite having sent, approximately six days before the SSD and AES

systems were activated, an email to the Cajon Valley Union School District’s counsel and

Ametek’s counsel requesting “to meet and confer as soon as possible and before any

remediation occurs to discuss next steps.” ECF No. 31-4, Exh. E at 19; ECF No. 42 at 2.

Plaintiffs argue Ametek should be sanctioned because it requested a delay in

meeting and conferring about inspection and testing, which Plaintiffs’ counsel respected,

and then turned on the depressurization systems, blatantly ignoring the previous

preservation emails without meeting or conferring, or even sending a notification that the

systems would be activated on September 16, 2015. Id. at 4:1-10. Plaintiffs argue the

timing of the systems’ activation suggests bad faith because it falls coincidentally on the

same day that Ametek’s counsel would finally be available to meet-and-confer.

Plaintiffs contend they are prejudiced because they intended to use initial

emissions data at trial to “help tell the story of what the conditions have been like for

students and teachers over the past decades prior to any remediation efforts” and because

such evidence can never be recovered or recreated. [ECF No. 31-1 at 4:6-8 and 10:25-27;

ECF No. 42 at 6:11-12.]

Plaintiffs’ expert, Anthony Brown, who is the chief executive officer and principal

hydrologist at consulting firm, Aquilogic, has opined in his declaration that: “SSD

systems, if operating as intended, change and impact the vapor conditions beneath the

foundation of the classrooms. The SSD systems change the conditions that existed

immediately before the SSD system was turned on, and the SSD systems also

continuously change the conditions as they continue to operate.” ECF No. 31-3 at ¶ 9. 

“One cannot go back in time to collect samples of vapor which existed immediately

before the SSD systems were turned on.” Id. at ¶10. “Since ERM6

 did not collect any

vapor samples, there are no samples from the initial emissions.” Id. at ¶11. “This

evidence is important because the vapor samples would have provided information about

the sub slab vapor conditions that were impacting the classrooms prior to the operation of

the SSD.” Id. at ¶13.

“ERM” is an abbreviation for Environmental Resources Management, the environmental

consulting firm that is conducting the Pilot Tests at Magnolia Elementary. Mai Decl. at ¶¶2-8.

B. Defendant Ametek Argues Spoliation Is An Impossibility Given That

Initial Emissions Data, To The Extent It Is Relevant, Can Be Regenerated

Ametek argues Plaintiffs did not put it on notice at the September 1, 2015,

inspection of Magnolia Elementary that they wished to record initial emissions data or

install sample ports before the SSD and AES units were activated. Ametek contends

Plaintiffs and their experts were aware that installation of the systems, which were

approved by the California Department of Toxic Substance Control and the Cajon Valley

School District, would be started sometime in mid-September 2015. [ECF No. 40 at 6:11-

17.] Ametek suggests it is Plaintiffs who are operating in bad faith by allowing their

experts to remain silent about collection of initial emissions data until after they knew the

systems had been activated in order to manufacture a spoliation issue. 

Ametek asserts that even if data was not captured by the failure to record initial

vapor emissions, such data is not relevant because “the air at issue for inhalation in this

case is in the classrooms, not in an exhaust pipe to the outdoors for air trapped under

buildings.” Id. at 6:22-27. Moreover, putting relevance questions aside, Ametek also

contends Plaintiffs’ accusation of prejudicial spoliation is overstated because “there has

been a large variety and mount of soil vapor, indoor and outdoor air, and ground water

samples collected over the last approximately 20 years that have provided a baseline

condition beneath [Magnolia Elementary School] prior to the commencement of the Pilot

Tests....which are part of the public record.” [ECF No. 40-1, Mai Decl. at ¶21.] Ametek

also argues there is no prejudice to Plaintiffs because the initial emissions data can be

recaptured. Id. at 6:27-7:2.

Ametek’s expert, Truong Mai, who is a civil engineer and partner with

Environmental Resources Management has opined in his declaration that: “Although

vapor samples were not collected prior to start-up of the SSD and AES units, nearly

identical conditions can be recreated to facilitate such sample collection if desired. The

soil vapor conditions beneath the rooms where SSD and AES units are installed can be

replicated easily... The SSD and AES units are not designed to, nor are they capable of,

remediating or materially changing the VOC concentrations in the groundwater plume or

the soil beneath the classrooms itself. If the SSD and AES units stop operation for a few

days, the relatively modest air flow that they induce in the subsurface would cease, thus

restoring soil vapor conditions to those similar to prior initiation of the pilot test. At

which time, Plaintiff’s expert can collect the desired vapor samples during re-startup of

the Pilot Test systems.” Mai Decl. , ECF No. 40-1 at ¶ 24.

IV. Standard of Review

Spoliation is the “destruction or significant alteration of evidence, or the failure to

preserve property for another’s use as evidence in pending or reasonably foreseeable

litigation.” Reinsdorf v. Skechers U.S.A., Inc., 296 F.R.D. 604, 626 (C.D. Cal. 2013)

(quoting Zubulake v. UBS Warburg LLC, 220 F.R.D. 212, 226 (S.D.N.Y. 2003)

(“Zubalake IV”). District courts can sanction a party who has despoiled evidence under

its inherent power “to levy sanctions in response to abusive litigation practices.” Leon v.

IDX Systems Corp., 464 F.3d 951, 958 (9th Cir. 2006). Depending on the case,

appropriate sanctions may include dismissing claims, drawing adverse inferences about

the content of evidence destroyed, excluding testimony and evidence, or awarding fees

and costs. Id.; Glover v. BIC Corp., 6 F.3d 1318, 1329 (9th Cir.1993); In re Napster, Inc.

Copyright Litigation, 462 F.Supp.2d 1060, 1070-78 (N.D. Cal.2006). It is the burden of

the moving party to show sanctionable conduct and prejudice. Reinsdorf, 296 F.R.D. at

626.

V. Discussion

The Court’s inherent power to impose evidentiary sanctions is discretionary. 

Glover v. BIC Corp., 6 F.3d 1318, 1328 (9th Cir. 1992) (explaining “[a] federal court has

the inherent discretionary power to make appropriate evidentiary rulings in response to

the destruction or spoliation of relevant evidence.”) Consequently, the simple alteration

or even destruction of evidence “does not necessarily mean that the party has engaged in

sanction-worthy spoliation.” See Reinsdorf , 296 F.R.D. at 626 (quoting Ashton v. Knight

Transp., Inc., 772 F.Supp.2d 772, 799-800 (N.D. Tex.2011).

A. Are Evidentiary Sanctions Appropriate?

As noted above in the Standard of Review section supra, a party moving for

evidentiary sanctions, including an adverse inference jury instruction, has the burden of

demonstrating: “(1) that the party having control over the evidence had an obligation to

preserve it at the time it was destroyed; (2) that the records were destroyed with a

‘culpable state of mind’; and (3) that the evidence was ‘relevant’ to the party’s claim or

defense such that a reasonable trier of fact could find that it would support that claim or

defense.” Reinsdorf, 296 F.R.D. at 626 (quoting Zubulake IV, 220 F.R.D. at 220); Apple,

Inc. v. Samsung Electronics Co., Ltd., 881 F. Supp. 2d 1132, 1138 (N.D. Cal. 2012)

(“Apple I”).

1.) There was an obligation to preserve evidence of Magnolia

Elementary’s property conditions.

 The spoliation analysis begins with the point at which Ametek became obligated

to preserve evidence relevant to Plaintiff’s toxic tort action. Apple, Inc. v. Samsung

Electronics Co., Ltd., 888 F. Supp. 2d 976, 991 (N.D. Cal. 2012) (“Apple II”) (explaining

trial courts in the Ninth Circuit generally agree that as soon as a potential claim is

identified, a litigant is under a duty to preserve evidence which it knows or reasonably

should know is relevant to the action.) Plaintiffs’ counsel sent preservation emails: (1) on

June 25, 2015, requesting “all evidence of Magnolia’s current property conditions be

maintained” until a meet-and-confer regarding testing and inspection could be completed;

(2) on August 27, 2015 indicating that after the visual site inspection on September 1,

2015, Plaintiffs were “planning a follow up to take samples”; and (3) on September 10,

2015, requesting “to meet and confer as soon as possible and before any remediation

occurs to discuss next steps.” [ECF No. 31-4, Exh. A at 2; Exh D. at 12-13; and Exh. E at

19.] 

It is clear Ametek’s duty to preserve evidence was triggered several months before

the alleged spoliation with the filing of Plaintiffs’ state court complaint on May 29, 2015.

[ECF No. 1-3.] Moreover, Ametek was aware from Plaintiffs’ counsel’s various emails

9 15cv1394 GPC (BGS)

in June, August and September of 2015 that Plaintiffs were generally interested in testing,

inspecting and sampling property conditions at Magnolia Elementary at some point.

2.) A Negligent State of Mind is Sufficient to Impose Sanctions.

In the Ninth Circuit, “a party’s destruction of evidence need not be in ‘bad faith’ to

warrant a court’s imposition of sanctions.” See Reinsdorf, 296 F.R.D. at 627 (quoting In

re Napster, Inc. Copyright Litigation, 462 F. Supp.2d 1060, 1066 (N.D. Cal. 2006)). 

Within the range of culpable mindsets, even “negligent destruction of evidence may, in

the proper circumstances, warrant some form of sanction.” Reinsdorf, 296 F.R.D. at 

627-28 (explaining the negligent destruction of evidence may be sanctioned because a

party should bear the risk of its own negligence.) 

Ametek’s argument that it did not know, because it was not informed at the

September 1, 2015 inspection, that Plaintiffs would want to install sample ports or take

initial emissions readings, does nothing to change the court’s analysis of this factor

because negligence is a sufficiently culpable state of mind in the context of spoliation

sanctions. It was careless for Ametek to go forward with pilot testing because it received

Plaintiffs’ preservation letters asking for the maintenance of current property conditions

at Magnolia Elementary and it received Plaintiffs’ emails asking for a meet-and-confer 

before any remediation occurred. Ametek was also aware that the SSD and AES systems

would change the current conditions at the property, even if only temporarily; therefore

Ametek’s negligent mindset suffices for the purpose of imposing a sanction. 

3.) Evidence at issue was relevant to Plaintiff’s toxic tort claim for

vapor intrusion7

.

Spoliation requires an awareness that the evidence destroyed was potentially

relevant to the litigation before it was destroyed. U.S. v. Kitsap Physicians Service, 314

F.3d 995, 1001 (9th Cir. 2002). Ametek argues it did not consider vapor samples of the

air under the classrooms relevant because the air that students and teachers inhale is

7

Plaintiffs allege claims of negligence, gross negligence and public nuisance, which

survived Defendant’s motion to dismiss. See FAC at ECF No. 21; and Order Granting In

Part/Denying in Part Ametek’s Motion to Dismiss at ECF No. 43.

found inside the classroom and not outdoors. While indoor classroom air may ultimately

be the focus of Plaintiffs’ toxic tort claim, it is clear vapors migrating upward and out

from the soil underneath Magnolia Elementary are a factor in the final air quality

equation inside the classroom. See Plaintiffs’ Expert Declaration at ECF No. 31-3,

Brown Decl., ¶13 (stating: “This evidence is important because the vapor samples would

have provided information about the sub slab vapor conditions that were impacting the

classrooms prior to the operation of the SSD.”); ECF No. 21 at ¶¶ 49-51; see also

Ametek’s Expert Declaration at ECF No. 40-1, Mai Decl., ¶12 (stating “[t]he

recommended standard of practice for assessing the potential impact to human health is

the collection of air samples, outdoor and indoor.” ) and Mai Decl., ¶20 (admitting that

while chemical samples are not being collected from outdoor exhaust sample ports

located on the SSD and AES units, “chemical samples are instead being collected

generally from the outdoor air (to establish an ambient baseline)...”

The Court also rejects Ametek’s argument that initial emissions evidence is

irrelevant given the Ninth Circuit’s recognition that the relevance of destroyed or

unavailable evidence “cannot be clearly ascertained because the [evidence] no longer

exist[s]”; therefore, a party “can hardly assert any presumption of irrelevance” as to the

destroyed evidence. Leon v. IDX Systems Corp., 464 F.3d 951, 959 (9th Cir. 2006)

(quoting Alexander v. Nat’l Farmers Org., 687 F.2d 1173, 1205 (8th Cir. 1982). This

reasoning applies here, where initial vapor emissions samples were never recorded, so the

Court cannot make an informed evaluation as to what those samples would, or would not,

have shown. Accordingly, the Court finds that vapor samples of initial emissions results

have relevance. 

B. Which Sanction Should Be Imposed?

Out of the various sanctions available to address an incident of spoliation, an

adverse inference instruction has been recognized by the district courts as a “severe

sanction.” Apple, Inc. v. Samsung Electronics Co., Ltd., 888 F. Supp. 2d 976, 994 (N.D.

Cal. 2012) (“Apple II”); Olney v. Job.com, 2014 WL 5430350, *16 (E.D. Cal. 2014)

(finding an adverse inference appropriate where Plaintiff’s degree of culpability was high

and defendant’s degree of prejudice as a result, was high); Moore v. Gilead Sciences, Inc.

2012 WL 669531, *5 (N.D. Cal. 2012) (stating “an adverse inference instruction is ‘an

extreme sanction and should not be taken lightly.’”); In re Hitachi Television Optical

Black Cases, 2011 WL 3563781, *11 (S.D. 2011) (recognizing adverse inference

instruction is a “harsh remedy”). 

In order to decide which degree of sanction is appropriate to impose, courts

generally consider: “(1) the degree of fault of the party who altered or destroyed the

evidence; (2) the degree of prejudice suffered by the opposing party; and (3) whether

there is a lesser sanction that will avoid substantial unfairness to the opposing party.” 

Apple II, 888 F. Supp. 2d. at 992. 

Additionally, “when the spoliating party was merely negligent [as the Court has

found to be the case here], the innocent party must prove both relevance and prejudice in

order to justify the imposition of a severe sanction.” See Reinsdorf, 296 F.R.D. at 627

(quoting Pension Comm. Of the Univ. Of Montreal Pension Plan v. Banc of America

Securities, LLC, 685 F.Supp. 2d 456, 467 (S.D.N.Y. 2010). Having already found

relevance, the Court will consider the additional factors of fault, prejudice (which is

required for an adverse inference instruction) and the availability of lesser sanctions in

turn below.

1.) Degree of fault of the party who altered or destroyed the evidence. 

Ametek is not the only entity responsible for the scheduling of the SSD and AES

pilot tests. The pilot tests were undertaken in conjunction with the California Department

of Toxic Substance Control and the Cajon Valley Union School District, both of which

are not parties to this lawsuit. It is important to note that counsel for the Cajon Valley

Union School District also received Plaintiffs’ counsel’s September 10, 2015, email

requesting “to meet and confer as soon as possible and before any remediation occurs to

discuss next steps.” ECF 31-4, Exh. E at 19. In response to this email, counsel for the

Cajon Valley Union School District replied to Plaintiff’s counsel, Ametek’s counsel and

Senior Operations’ counsel on September 11, 2015, stating: “The District wants to

cooperate with these efforts, but does not want this process to delay installation of

engineering controls.” Id., Exh. H at 25. The Court was not provided with any emails

that responded to the concerns of the School District’s counsel about avoiding delay.

Nevertheless, it is evident that additional forces, not just Ametek, were factors in

scheduling the pilot test activation.

Given the fact that: (1) non-parties also had input into the pilot test startup

schedule; and (2) Ametek proceeded with the pilot testing not in bad faith, but

negligently in light of its receipt of the generalized preservation letters and nonspecific

requests to meet and confer, the Court finds the degree of culpability on Ametek’s part is

low. This militates against the imposition of an adverse inference instruction. 

2.) Degree of prejudice suffered by the opposing party. 

Plaintiffs’ expert, Anthony Brown, opines in his declaration that “one cannot go

back in time to collect samples of vapor which existed immediately before the SSD

systems were turned on” and “one cannot go back in time to collect samples of vapor

which existed in the moments immediately after the system began.” [ECF No. 31-3 at

¶10. While this is true, the Ninth Circuit has nevertheless recognized that the availability

of other evidence can mitigate prejudice caused by a loss of primary evidence. Med. Lab

Mgmt. Consultants v. Am. Broad. Cos., Inc., 306 F.3d 806, 825 (9th Cir. 2002) (explaining

that when original evidence has been lost, proof by secondary evidence is permissible). 

Plaintiffs do not dispute that Magnolia Elementary has been assessed for impact to soil

and groundwater since 1994 resulting in “numerous soil vapor, groundwater , and air

samples (outdoor and indoor) over the last 20 years. ECF No. 40-1, Mai Decl., at ¶7-8. 

Ametek’s expert has opined, and Plaintiffs did not object, that “there have been a large

number of soil vapor samples collected from Magnolia Elementary School” and “there

has been a large amount of outdoor and indoor air samples collected from Magnolia

Elementary School.” Id., at ¶11-12. And in fact, Plaintiffs’ First Amended Complaint

cites authoritatively to recent vapor intrusion indoor air quality test results and ambient

air sampling done at Magnolia Elementary by the California Department of Toxic

Substance Control from August, November, and December of 2014 as well as from

March 2015. ECF No. 21 at ¶¶46-55.

There appears to be a generous amount of material available to Plaintiffs to provide

information about the sub slab vapor conditions affecting the Magnolia Elementary

classrooms prior to the start of the pilot testing.

In addition to the existence of other historic outdoor and indoor air sample

evidence, more current evidence may still be acquired. Ametek’s expert has explained:

“although vapor samples were not collected prior to start-up of the SSD and AES units,

nearly identical conditions can be recreated to facilitate such sample collection if

desired.” Specifically, Ametek’s expert has opined: 

“If the presence of volatile organic compounds (VOCs) in indoor air at Magnolia

Elementary School (MES) is from vapor intrusion, the same VOCs would need to

migrate from soil vapor beneath MES, which would need to volatize from the same

VOCs in the groundwater plume originating from the Greenfield Facility. The

VOC concentrations in the groundwater plume are very stable and do not changed

materially quickly, as demonstrated by over 28 years of monitoring. The SSD and

AES units are not designed to, nor are they capable of, remediating or materially

changing the VOC concentrations in the groundwater plume or the soil beneath the

classrooms itself. If the SSD and AES units stop operation for a few days, the

relatively modest air flow that they induce in the subsurface would cease, thus

restoring soil vapor conditions to those similar to prior initiation of the pilot test. 

At which time, Plaintiff’s experts can collect the desired vapor samples during restartup of the Pilot Tests systems.”

ECF No. 40-1, Mai Decl., at ¶24.

The Court finds prejudice in this case is slight because vapor intrusion testing and

sampling has previously occurred and been documented by the California Department of

Toxic Substance Control before the SSD and AES units were activated at Magnolia

Elementary in September of 2015. The prejudice to Plaintiffs in this case is also minimal

because the sampling of sub slab conditions that Plaintiffs seek to do can still be done

upon cessation and re-initiation of the pilot testing systems. Thus, this factor weighs

against imposing an adverse inference instruction. 

3.) Lesser sanctions to avoid substantial unfairness to opposing party.

There are lesser sanctions available to the Court under its inherent power other

than the severe adverse inference instruction requested by Plaintiffs, including the

discretion to award fees and/or costs. Leon v. IDX Systems Corp., 464 F.3d 951, 958 (9th

Cir. 2006). In this case, there is a low degree of culpability and an even lower degree of

prejudice given that pre-pilot test indoor and outdoor air sample results are available in

the public record and vapor sampling can still be taken at Magnolia Elementary. This

Court is also mindful of the principles behind the court’s inherent powers, which require

such sanctioning power to be “applied with restraint and discretion and only to the degree

necessary to redress the abuse.” See Reinsdorf, 296 F.R.D. at 62c7 (quoting Chambers v.

Nasco, Inc., 501 U.S. 32, 45, 111 S. Ct. 2123, 115 L.Ed.2d 27 (1991). Accordingly,

Plaintiff’s request for the severe sanction of an adverse inference jury instruction is

DENIED.

In order to place Plaintiffs in substantially the same position as they would have

been absent the failure of Ametek to sample initial vapor emissions before the activation

of the SSD and AES systems, the Court finds Ametek must cease operation of the pilot

test SSD and AES units in order to restore soil vapor conditions at Magnolia Elementary

to those similar to condition before pilot testing was initiated. Plaintiff’s experts shall

also be permitted to collect vapor samples at the re-startup of the SSD and AES systems.

 Finally, to prevent any further negligent or inadvertent spoliation at the property

the Court also requires Ametek to provide Plaintiffs with 30-days notice before

conducting further remediation efforts at Magnolia Elementary.
