601447589v1 - 2 -CHEVRON EMC'S PETITION FOR REVIEW

1 B. THE SPECIFIC ACTION OF THE REGIONAL BOARD THAT THE

2 STATE BOARD IS REQUESTED TO REVIEW.

3 Petitioner seeks rescission of the directives contained in the Regional Board's April

4 26, 2011 Order which are vague, ambiguous, overly broad and duplicative of other

5 Regional Board orders. Specifically, Petitioner seeks rescission of-the Order insofar as it

6 attempts to require it to: (1) investigate a former Texaco service station, which has already

7 been extensively investigated pursuant to an open Regional Board Leaking Underground

8 Storage Tank ("LUST") case and which data indicate is not reasonably considered a

9 potential source of the petroleum release in the Dominguez Channel; and (2) investigate the

10 undefined "Site," which presumably is intended to encompass the Dominguez Channel and

11 properties in the vicinity, none of which Petitioner owns or operates, and over which it has

12 no control or right of access.

13 The Order exceeds the scope of the Regional Board's investigatory authority under,

14 Water Code section 13267 because the burden of the directive does not bear a reasonable

15 relationship to the need for the work directed or the benefits to be gained by it, which are

16 not supported by evidence in the Order. See Cal. Wat. Code § 13267 (b)(1).

17 C. THE DATE ON. WHICH THE REGIONAL BOARD ACTED OR

18 FAILED TO ACT.

19 The Regional Board acted on April 26, 2011 when it issued the Order.

20 D. STATEMENT OF REASONS THE ACTION OR INACTION WAS

21 INAPPROPRIATE AND IMPROPER.

22 1. History of the Order.

23 In January 2011, a petroleum release from the bottom of the Dominguez Channel

24 was discovered. On April 26, 2011, the Regional Board issued Orders' to 'Chevron

25 Pipeline', Chevron Environmental Management Company, ConocoPhillips Company,

26

27 1 Petitioner has not seen the text of the orders to all of the other recipients, but presumesthey are the same.

28


1 Crimson Pipeline, Shell Oil Products US, Tesoro Corporation, Prowell Family Trust, and

2 BP Pipelines, naming them as potentially responsible parties for approximately 13 different

3 "petroleum facilities" in the vicinity of the Dominguez Channel. See Gaylord Decl., Ex. 1.

4 The facilities for which these entities are responsible include current and former service

5 stations, various pipelines, -a former air_harbor facility and an active petroleum terminal,

6 among others. Id. Several of these facilities are already under unrelated Regional Board

7 orders. Id.

8 The Order requires the recipients to submit:

9 1. By June 8, 2011, a work plan to delineate the vertical and lateralextent of petroleum impact in the vicinity of the release. The work plan

10 shall be prepared with the intent of determining (1) the extent of petroleumimpact from the Site and (2) if your facility has contributed to the Release in

11 the Dominguez Channel. The work plan shall place an emphasis onexpedient groundwater delineation but shall also include plans to delineate

12 soil and soil gas impacts. The work plan shall propose initial samplinglocations, describe proposes sampling and analysis techniques, provide a

13 proposed timeline for activities, and include provisions for follow-up workin the event the proposed work does not sufficiently define the extent of

14 impact.

2. After Approval by the Regional Board ExecutiVe Officer, implement15 the work plan and report results in accordance with the approved work plan

16schedule.

17 Id. The Order does not define the term "Site."

18 The Order states that the work it directs is necessary "to determine (1) the extent of

19 petroleum impact beneath and near the ongoing release in the Dominguez Channel,

20 approximately 400 feet south of Carson Street in Carson, California and (2) whether your

21 facility has contributed to the petroleum release." Id. The Order represents that the

22 evidence justifying the burden imposed by it is the "operation of a petroleum facility near

23 the release site." Id. In addition, a table attached to the Order, entitled "Recipients of MVO

24 Section 12367 Orders Associated with a Petroleum Release near Carson Street in the

25 Dominguez Channel," purports to explain the "Basis for Order" as it pertains to each of the

26 recipients. Id. However, the information contained in the table with regard to the former

27 Texaco station includes references to data, with no citation as to the source of the data

28 referenced. Gaylord Decl., Ex. 1. Presumably the table intended to reference the maximum601447589v1 - 4 -


1 on-site concentrations of petroleum constituents detected, however, if that is the case the

2 data presented are not accurate, and Petitioner cannot determine where the data contained in

3 the table originated. Declaration of Rob Speer ("Speer Decl.") all 3.

4 After receiving the Order, Petitioner responded to the Board by letter dated May 6,

5 2011 (Gaylord-DeclExT-2)Tchallenging-the-sufficiency-ofthe-evidence-presented in the

6 Order, and whether the burden of the Order was reasonable in light of the costs to comply

7 with it. See Cal. Water Code § 13267(b)(1). On May 24, 2011, Petitioner received a

8 response from the Regional Board indicating, among other things, that the Order to "CEMC

9 regarding the former Texaco Service Station is not rescinded." Gaylord Decl., Ex. 3.

10 On May 13, 2011, the Regional Board held a meeting in Los Angeles with the Order

11 recipients. Representatives attended on Petitioner's behalf. Gaylord Decl. 115. According

12 to information presented by the Regional Board project manager for the Order, Greg

13 Bishop, petroleum was discovered "daylighting" from the bottom of the Dominguez

14 Channel in January 2011. See Gaylord Decl., Ex. 4 at 3. Since then, Los Angeles

15 Department of Water and Power ("LADPW"), the owner and operator of the Channel, has

16 been undertaking capture activities in the Channel. Id. at 5. Apparently, only very limited

17 sampling of the petroleum product found in the Channel has been conducted. According to

.18 the Regional Board, data indicate that the product found in the seep is refined petroleum,

19 likely a gasOline and/or jet fuel range hydrocarbon. Id. at 22-24. An additional source of

20 petroleum to the Channel from what appears to be a distinct petroleum product has been

21 detected in subdrain piping running in the levees along the sides of the Channel. Id.

22 On May 17, 2011, the Regional Board issued a Cleanup and Abatement Order

23 ("CAO") to the Los Angeles Department of Public Works ("DPW"), directing it to "assess,

24 monitor, cleanup the waste, and abate the effects of the ongoing discharge of LNAPL and

25 other wastes within the Dominguez Channel, approximately 400 feet south of Carson Street

26 in Carson, California." Gaylord Decl. Ex. 5.

601447589v1 5 -CHEVRON EMC'S PETITION FOR REVIEW

1 2. The Former Texaco Station.

2 The Order directs Petitioner to investigate a former Texaco station at 1209 E.

3 Carson Street. The USTs and fueling equipment were removed from the former Texaco

4 station in the late the 1970s and it has not been operated as a service station since that time.

5 Petitioner has been engaged in the investigation and cleanup of the former station site since

6 the late 1990s. Speer Dec1.114. Since then, it has installed an extensive monitoring well

7 system, consisting of 16 on-site and off -site monitoring wells. Petitioner has sampled these

8 wells under the oversight of the Regional Board since their installation in approximately .

9 1996, and remains under an open environmental case for the site through the Regional

10 Board's LUST program (Regional Board case number UST: R-05994). Id. Petitioner is in

11 compliance with directives for the LUST case, and has not been directed to complete the

12 work for the site now directed under the Order as part of the existing environmental case.

13 Id. See, < http ://geotracker. swrcb . ca. gov/profile report. asp ?globalid=T0603722212>.

14 The data collected from the LUST site monitoring program indicates a declining

15 trend of petroleum detections in the on-site wells near the former UST release source

16 enough so that monitoring frequency was reduced from quarterly to semi-annually in 2010.

17 Speer Decl. ¶ 5. The Order ignores this recent data. Instead, it reports as justification for

18 the issuance of the Order what presumably purport to be maximum concentrations from the

19 site. However, the referenced, concentrations are not consistent with either maxitmun

20 concentration data from the site, or the relevant recent data. Speer Decl. ¶ 3.

21 The third and fourth Quarter 2010 groundwater monitoring data from the station site

22 demonstrate that the remaining impacts are largely in off -site wells and are not reasonably

23 attributed to the long past release from the former service station. Speer Decl. ¶ 6. Higher

24 maximum soil concentrations are currently observed off-site than were seen on-site even in

25 the early stages of investigation near the former tanks and dispensers. The locations and

26 depths of highest concentrations clearly follow the geometry of the streets where known

27 pipelines and utilities exist. Speer Decl. Ex. 1. And contrary to the suggestion in the "basis

28 for order" section of the table enclosed with the Order, separate phase hydrocarbons (e.g.,601447589v1 - 6 -


1 free product), were not detected at a measurable thickness in groundwater until recently in

2 MW-9 on June 24, 2010, when 0.03 feet was measured. The fact that the levels were not

3 measurable in the many years of prior monitoring is evidence that the recent concentration

4 increases are from an off-site source. Speer Decl. ¶ 6.

5 Furthermore, historic borings -in -the- vicinity of the site's former source areas have

6 vertically delineated the potential impact that may have resulted from the equipment.

7 Additional vertical investigation in these areas would not serve to further delineate the

8 nature of the release from on-site due to the depth of groundwater in the area. Speer Decl.

9 ¶ 7. The maximum concentration of TPH-g in soil was detected in the vicinity of the

10 former USTs in boring B-1 at 15 feet bgs (3,700 mg/kg). Id. However, the concentration

11 detected in the next deepest sample from B-1 (17.5 feet bgs) was less than half (1,300

12 mg/kg) that of the 15 foot sample. Id. Similarly, the analytical results for the other on-site

13" borings exhibit declining concentration trends with depth. Id.

14 There are known pipeline releases up-gradient of the service station location, which

15 can explain the concentrations seen in the wells adjacent to the pipelines especially since,

16 despite being open Regional Board cases, it appears those releases have not been

17 investigated. All indications are that the current detections in Petitioner's monitoring well

18 network are from off -site sources and not from the former service station. Speer Decl. ¶ 8.

19 3. The "Site".

20 In addition :to investigating its facility and any off -site impacts from it, the order

21 directs Petitioner to investigate some undefined "Site." As explained during the meeting

22 with the Regional Board, the assessment goals of this Order are:

23 1. Physical subsurface sampling to fully delineate soil, groundwater andsoil gas impact around petroleum infrastructure and the Dominguez

24 Channel (including the connection to subdrain systems and the bottom ofthe channel).

25 LNAPLOther petroleum (dissolved phase, soil gas, etc.)

26 Other contaminants (?)Full lateral and vertical extents

27 Connection to bottom of channelConnection to subdrains

28 e Transport along subdrains601447589v1 - 7 -


1 2. Gain an understanding of the subsurface conditions delivering LNAPL tothe channel bottom and the levee subdrains.

2 3. Determine whether individual petroleum infrastructures are contributingto the Dominguez Channel release.

3 4. Complete sufficient assessment to ,design a remediation approach.5. Collaborate to improve efficiency to achieve Goals 1 to 4.

4 Faster resultsBetter results

5 Lower Costs

6 Gaylord Decl., Ex. 4 at 27-39 (emphasis in original). Petitioner understands the Regional

7 Board's goals, in combination with the vague language of the Order, to require the Order

8 recipients to investigate and delineate the scope of impacts some undefined area in and near

9 the Channel itself, despite having ordered DPW to cleanup and abate any ongoing releases

10 at the Channel, and despite the fact that DPW is the owner and operator of the Channel and

11 the entity with control or access to the Channel. Gaylord Decl. Exs. 4-5.

12 4. The Burden of the Order is Not Justified In Light of the

13 Limited/Non-Existent Benefits to Be Gained by It.

14 Due to the vague nature of the Order, it is not clear what Petitioner is expected to do .

15 to comply with it. It appears that the Regional Board expects Petitioner to prepare a new

16 work plan and conduct further investigation of the former Texaco station site, as well as

17 some unidentified area in the vicinity of, and including, the Dominguez Channel. The cost

18 and burden of preparing such a work plan is disproportionate to the need and benefits to be

19 gained by the report. California Water Code Section 13267(b)(1) states, in part: "The

20 burden, including costs, of these [technical] reports shall bear a reasonable relationship to

21 the need for the report and the benefits to be obtained from the reports." Moreover,

22 evidence from old investigations that does not support continuing investigation

23 requirements, is not a valid basis for an investigatory Order pursuant to Water Code section

24 13267, See In the Matter of the Petition of Chevron Products Company, 2004 WL

25 1371359, at 4 (Cal. St. Wat. Res. Bd., Order WQO 2004-2005)(May 20, 2004).

26 The burden imposed by the Order has not been properly justified, in light of the

27 following:

28


1 The Texaco station is currently under oversight of the Regional Board's

2 UST program and any work done pursuant to this Order may conflict,

3 duplicate or repeat work already completed. Thus, if Petitioner were to

4 attempt to comply with the Order as directed to the former Texaco station, it

5 would be-under-two distinct regulatory orders -from -the same agency.

6 Moreover, the LUST case is approaching closure. Nevertheless, premised

7 on the same UST release that opened the LUST-case, the Regional Board

8 now demands Petitioner again investigate not only the service station

9 property, but other undefined areas as well. Petitioner is faced with

10 potentially conflicting, or at a minimum, duplicative orders for its former

11 service station site;

12 The directive to the former Texaco station is not justified based on the data.

13 The Order appears to be premised on old, (inaccurate) maximum

14 concentration levels from the station, when the current station data clearly

15 indicate that an off-site source is impacting Petitioner's wells likely the up-

16 gradient pipeline releases which have not been fully investigated.

17 Additional further delineation of the site is not warranted based on existing

18 data. By failing to consider the current, property status and the extensive

19 existing data, the conclusion that the former service station could be a source

20 of petroleum to the Channel is unsupported and the directive to further

21 investigate is unwarranted;

22 The demand to investigate the "Site ", is vague and undefined such that no

23 recipient can reasonably understand what they are required to do to comply.

24 It is also duplicative of other orders, and does not bear a reasonable

25 relationship to the sites to which the Order is directed;

26 Assuming the directive intends to have Petitioner investigate the Channel

27 and its vicinity, Petitioner does not own, operate or have access other than

28


1

2

to its own former site to the area of the Dominguez Channel or the

Channel itself. Moreover, most of the property owners in the vicinity of the

Channel located between the Channel and the former Texaco station have

themselves been directed to investigate those properties; and,

The CAO to DWP, the Channel-owner-and-operator, to cleanup and abate

the release in the Channel overlaps with the scope of the investigation of the

"Site" as apparently required by the Order.

In sum, submission of a work plan and investigation by Petitioner of the Channel

9 release is futile given existing data which already delineate the Texaco service station site,

10. and is a waste of resources under these circumstances. The Order does not meet the

11 requirement of Water Code section 13267 that the need for the work required bear a

12 "reasonable relationship" to the burden of completing it and exceeds the Regional Board's

13 authority under Water Code section 13267.

14 E. THE MANNER IN WHICH THE PETITIONER IS AGGRIEVED.

15 The requirement to prepare a work plan to investigate a former Texaco facility

16 already under Regional Board jurisdiction aggrieves Petitioner because it is vague, overly

17 broad, fails to consider work already done by Petitioner under an existing LUST case under

18 the Regional Board's oversight, is not justified in light of current data which the Order fails

19 to consider, requires investigation of properties outside the scope of Petitioner's control,

20 and duplicates/conflicts with directives to Petitioner and other parties. The Order demands

21 preparation of a work plan and investigation, which is an unreasonable expense in light of

22 these facts.

23 F. THE SPECIFIC ACTION BY THE STATE OR THE REGIONAL

24 BOARD THAT PETITIONER REQUESTS.

25 Petitioner requests that the State Board rescind the Order. Petitioner will comply

26 with reasonable requirements to investigate the Texaco station pursuant to the open LUST

27 case for that site, consistent with the existing data., Petitioner also requests a Stay of the

28 June 8, 2011 due date presented in the Order.


1 G. A STATEMENT OF POINTS AND AUTHORITIES IN SUPPORT OF

2 LEGAL ISSUES RAISED IN THE PETITION.

3 Petitioner's initial statement of points and authorities is set forth herein above.

4 Petitioner reserves the right to supplement this statement and file additional points and

5 authorities at a future date -upon receipt and-review of the administrative record and-as

6 additional information and evidence is developed.

7 H. STATEMENT THAT THE PETITION HAS BEEN SENT TO THE

8 REGIONAL BOARD AND TO. THE DISCHARGER, IF NOT THE

9 PETITIONER.

10 A copy of this Petition has been sent to the Regional Board, and will be transmitted

11 to the other named parties in the Order.

12 I. STATEMENT THAT THE SUBSTANTIVE ISSUES OR

13 OBJECTIONS RAISED IN THE PETITION WERE RAISED

14 BEFORE THE REGIONAL BOARD.

15 The history of Plaintiffs communications with the Regional Board with regard to

16 this Order is set forth above.

17 J. THE PETITIONER REQUESTS A HEARING ON THE ORDER.

18 Petitioner requests a hearing on the Order. In support of this request, it makes the

19 following points:

20 (1) A summary of the arguments that Petitioner wishes to make at the

21 hearing is provided in the Petition above.

22 (2) A summary of the testimony or evidence the petitioner wishes to

23 introduce is provided in the Petition above, including all documents referenced in this

24 Petition, although Petitioner may supplement the testimony or evidence at the hearing.

25 II. REQUEST FOR STAY ORDER.

26 Petitioner requests a stay of the Order pending resolution of the issues raised in this

27 Petition. This stay request is based on the accompanying declarations of Amy E. Gaylord

28 and Rob Speer that demonstrate (1) substantial harm to the Petitioner if a stay is not601447589v1 11 -


1 granted; (2) a lack of substantial harm to other interested persons and to the public interest

2 if a stay is granted; and (3) substantial questions of fact or law regarding the disputed

3 action.

4 A. LEGAL GROUNDS FOR A STAY.

5 Pursuant-to section 2053 of the State Board's re ati-ons (23 CCR § 2053), a stay of

6 the effect ofan order shall be granted if the petitioner shows:

7 (1) Substantial harm to petitioner or to the public interest if a stay is not granted;

8 (2) A lack of substantial harm to other interested parties and to the public if a

9 stay is granted; and

10 (3) Substantial questions of fact or law regarding the disputed action exist.

11 These requirements are met in this case.

12 1. Petitioner Will Suffer Substantial Harm if a Stay Is Not Granted.

13 Petitioner challenges the Order on the grounds that the Regional Board does not

14 meet the burden required under California Water Code Section 13267 to show that the need

15 and benefits of a work plan outweigh the significant costs to be incurred in its preparation.

16 The Order requires the submittal of a work plan to evaluate a service station

17- property that already has been investigated under an unrelated Regional Board case, as well

18 as some undefined "Site." The cost of submitting and implementing a work plan to

19 investigate the overly broad and undefined area in the vicinity of, and including, the

20 Dominguez Channel is presently incalculable, but given the apparent breadth of the Order

21 could potentially total several millions of dollars or more. These costs are unjustified given

22 the existence of the existing order for the site, and the data collected there to date. As a

23 result, these costs should be deemed unnecessary when the State Board acts on the Petition,

24 rendering the expenditure of money, time and resources to comply in the meantime a costly

25 exercise in futility. However, if Petitioner declines to expend money, time and resources in

26 an effort to produce a work plan for a site it already is investigating, it becomes exposed to

27 significant daily penalties for non-compliance with the Order. If a stay is not granted,

28 Petitioner therefore would be faced with a no-win scenario: expend substantial and601447589v1 - 12 -

CHEVRON MAC'S PETITION FOR REVIEW

1 unnecessary sums to prepare and implement an unnecessary work plan, or face substantial

2 monetary penalties for failure to produce the work plan. Speer Decl. ¶ 10. A stay until a

3 determination is made as to the cleanup goals would solve this problem and save Petitioner

4 from significant and substantial monetary harm. Id.

5 2. The Public Will Not Be Substantially Harmed-If-a Stay Is Granted.

6 As noted, above, Petitioner has conducted significant investigation of the former

7 Texaco service station site under an open UST case. Current data from the site does not

8 support the conclusion that the service station is a source of petroleum to the Channel.

9 Moreover, because a Cleanup and Abatement Order was issued to the owner/operator of the

10 Dominguez Channel, where the release is occurring, to clean up and abate it, the public will

11 not be harmed by issuance of a stay with regard to the Order to investigate the already

12 investigated Texaco service station. Gaylord Deci. Ex. 5.

13 Accordingly, the grant of a stay would not substantially harm the public.

14. 3. The Petition Raises. Substantial Questions of Law and Fact.

15 As. discussed above, there are significant questions being posed in this case as to

16 whether Order and requirement for completion of a work plan meets the burdens

17 established under California Water Code Section 13267. Petitioner disputes the benefit to

18 be derived from and need for any work plan the Regional Board require es in its Order.

19 There are, significant issues of fact and law that are sufficient to warrant the granting of a

20 stay.

3 ("EMC" or "Petitioner") in the instant action. This declaration is submitted in supportof

4 EMC's Petition to the State Board challenging the April 26, 2011 action of the California

5 Regional Water Quality Control-Board, Los Angeles Region ("Regional Board") in issuing

8 Management Company' Former Texaco Gasoline Station Chevron Facility no. 21-1316

9 1209 E. Carson Street, Carson, California (UST Case No. 21-1316)," (the "Order").

10 Unless otherwise stated, I have personal knowledge of the matters stated here in and could

11 and would testify competently thereto.

12 2. I am the EMC project manager for theTexaco Gasoline Station Chevron

13 Facility No. 21-1316 1209 E. Carson Street, Carson, California subject to Regional Board

14 UST Case No. 21-1316. Since March 2010, I have managed an outside consultant who has

15 done the field work at this facility. I am familiar with the investigation conducted to date at

16 the site and have reviewed the data collected in relation thereto.

17 3. I have reviewed the data for this site and compared it to the data contained in

18 the table attached to the Order. The data provided in the table with the Order does not

19 appear to be consistent with the maximum on site concentrations of petroleum constituents

20 detected and reported for the Site and I cannot determine where the data contained in the

21 table originated.

22 4. I understand and believe that the underground storage tanks ("UST") and

23 fueling equipment were removed from the former Texaco station in the late the 1970s and it

24 has not been operated as a service station since that time. Petitioner has been engaged in

25 the investigation and cleanup of the former station site since the late 1990s. Since that time,

26 it has installed an extensive monitoring well system, consisting of 16 on-site and off-site

27 monitoring wells. Petitioner has sampled these wells under the oversight of the Regional

28 Board since their installation in approximately 1996, and remains under an open

601447590v1 - 2DECL. OF ROB SPEER IN SUPPORT OF CHEVRON EMC'S PETITION

1 environmental case for the site through the Regional Board's LUST program (Regional

2 Board case number UST: R-05994). Petitioner is in compliance with directives for the

3 LUST case, and has not been directed to complete the work for the site now directed under

4 the Order as part of the existing LUST case.

5 5. I have reviewed the, data collected from the LUST site monitoring program

6 and it indicates a declining trend of petroleum detections in the on-site wells near the

7 former UST release source enough so that monitoring frequency was reduced from

8 quarterly to semi-annually in 2010.

9 6. The third and fourth Quarter 2010 groundwater monitoring data from the

10 station site demonstrate that the remaining impacts are largely in off-site wells and are not

11 reasonably attributed to the long past release from the former service station. Higher

12 maximum soil concentrations are currently observed off-site than were seen on-site even in

13 the early stages of investigation near the former tanks and dispensers. The locations and

14 depths of highest concentrations clearly follow the geometry of the streets where known

15 pipelines and utilities exist. And contrary to the suggestion in the "basis for order" section

16 of the table enclosed with the Order, separate phase hydrocarbons (e.g., free product), were

17 not detected at a measurable thickness in groundwater until recently in MW-9 on June 24,

18 2010, when 0.03 feet was measured. The fact that the levels were not measurable in the

19 many years of prior monitoring is evidence that the recent concentration increases are from

20 an off-site source. A copy of the Third and Fourth Quarter 2010 Monitoring Report for the

21 former Texaco service station Site is attached hereto as Exhibit 1.

22 7. Furthermore, historic borings in the vicinity of the site's former source areas

23 constitute vertical delineation of the potential impact that may have resulted from the

24 service station equipment. In my opinion, additional vertical investigation in these areas

25 would not serve to further delineate the nature of the release from on-site due to the depth

26 of groundwater in the area. The maximum concentration of TPH-g in soil was detected in

27 the vicinity of the former USTs in boring B-1 at 15 feet bgs (3,700 mg/kg). However, the

28 concentration detected in the next deepest sample from B-1 (17.5 feet bgs) was less than

601447590v1 3DECL. OF ROB SPEER IN SUPPORT OF CHEVRON EMC'S PETITION

1 half (1,300 mg/kg) that of the 15 foot sample. Similarly, the analytical results for the other

2 on-site borings exhibit declining concentration trends with depth.

3 8. I am aware that there are known pipeline releases up-gradient of the service

4 station location. These releases can explain the concentrations seen in the wells adjacent to

5 the pi lines and whichTdespitbeing open Regional Board cases, do not appear to have

6 been investigated. All indications are that the current detections in Petitioner's monitoring

7 well network are from off-site sources and not from the former service station.

8 9. If Petitioner were to attempt to comply with the Order as directed to the

9 former Texaco station, it would be under two distinct regulatory orders from the same

10 agency for the same site. The LUST case is approaching closure. Nevertheless, premised

11 on the same UST release that opened the LUST case, the Regional Board now demands

12 Petitioner investigate not only the service station property, but others. Petitioner is faced

13 with potentially conflicting, or at a minimum, duplicative orders for its former service

14 station site.

15 10. The costs of submitting and implementing a work plan to investigate the

16 overly broad and undefined area in the vicinity of, and including, the Dominguez Channel

17 are presently incalculable, but given the apparent breadth of the Order could potentially

18 total several millions of dollars or more. These costs are unjustified given the existing

19 order for the site, and the data collected there to date. As a result, these costs should be

20 deemed unnecessary when the State Board acts on the Petition, rendering the expenditure of

21 money, time and resources to comply in the meantime a costly exercise in futility.

22 However, if Petitioner declines to expend money, time and resources in an effort to produce

23 a work plan for a site it already is investigating, it becomes exposed to significant daily

24 penalties for non-compliance with the Order. If a stay is not granted, Petitioner therefore

25 would be faced with a no-win scenario: expend substantial and unnecessary sums to prepare

26 and implement an unnecessary work plan, or face substantial monetary penalties for failure

27 to produce the work plan. A stay until a determination is made as to the cleanup

28

601447590v1 - 4DECL. OF ROB SPEER IN SUPPORT OF CHEVRON EMUS PETITION

1 goals would solve this problem and save Petitioner from significant and substantial

2 monetary harm.

WORK PERFORMED DURING THIS REPORTING PERIOD (Third and Fourth Quarters 2010) :

1. Blaine Tech Services, Inc. (BTS) conducted groundwater monitoring and purge sampling of well MW-9 on August 27,2010, because well MW-9 was not sampled during the second quarter 2010 due to the presence of separate phasehydrocarbons (SPH). Neither measurable SPH nor sheen was observed during gauging; however, sheen was noted duringpurging the well. Field data sheets and waste disposal documentation for the third quarter event are included inAttachment A.

2. Blaine Tech Services, Inc. conducted semi-annual groundwater monitoring and sampling on December 2, 2010. No SPHwas detected in MW-9 during gauging. However, during purging an odor and sheen were observed. Sixteen monitoringwells were gauged and sixteen sampled during this sampling event. Field data sheets are included in Attachment A;however, waste disposal documentation is currently not available for the fourth quarter and will be submitted with thenext semi-annual monitoring report.

Groundwater samples were analyzed for total petroleum hydrocarbons as gasoline (TPH-g), total petroleum hydrocarbonsas diesel (TPH-d), oil range organics (ORO), and extractable fuel hydrocarbons (EFH) according to EnvironmentalProtection Agency (EPA) method 8015B. Groundwater samples were also analyzed for benzene, toluene, ethylbenzene,and total xylenes (BTEX, collectively), methyl tent -butyl ether (MTBE), di-isopropyl ether (DIPE), ethyl tert-butyl ether(ETBE), tert-amyl bntyl ether (TAME), and tcrt-butanol (TBA) by EPA method 8260B. The site location map, the siteplan, and the groundwater contour map are shown on Figures 1 through 3. Isoconcentration maps for TPH-g, TPH-d,ORO, EFH, benzene, and MTBE are shown on Figures 4 through 9. Current and historical groundwater data are inTables 1 and 2. A copy of the laboratory analytical report and chain-of-custody documentation for both events are inAttachment B.

WORK PROPOSED FOR THE NEXT REPORTING PERIOD (First and Second Quarters 2010):

1. Perform groundwater monitoring and related reporting.

2. Submit the fourth quarter 2010 waste documentation.

3. Submit a Case Closure Request.

Groundwater conditions during this reporting period remained generally consistent with previous events. The maximumconcentrations of TPH-g (35,000 micrograms per liter [.Lig/L]) and benzene (12,000 ug/L) were detected in the sample collectedfrom well MW-1. The maximum concentration of MTBE (5.2 1.1,g/L) *as detected in the sample collected from well MW-13.Dissolved concentrations of TBA were not detected at or above laboratory detection limits in any of the samples collected.

CONCLUSIONS AND RECOMMENDATIONS:

Groundwater concentrations in the vicinity of well MW-1 are likely associated with an off-site source. Additionally, ARCADISbelieves that an off-site source is responsible for the dissolved concentrations observed at the site because of the persistent highconcentrations of TPH-d. and ORO, which were never dispensed at the site and the recent occurrences of SPH sheen in MW-9.Therefore, ARCADIS plans to submit a request for closure based upon the sites low risk to human health and the environment.

DATA QUALIFIERS AND DEFINITIONS

MNR1 There was no 1VIS/MSD analyzed with this batch due to insufficient sample volume. See Blank Spike/Blank SpikeDuplicate.

Z2 Surrogate recovery was above the acceptance limits. Data not impacted.

Z3 The sample required a dilution due to the nature of the sample matrix. Because of this dilution, the surrogate spikeconcentration in the sample was reduced to a level where the recovery calculation does not provide usefulinformation:

ZX Due to sample matrix effects, the surrogate recovery was outside the acceptance limits.

itD Analyte NOT DETECTED at or above the reporting limit or MDL, if MDL is specified.

RPD Relative Percent Difference

ADDITIONAL COMMENTS

For 8260 analyses:

Due to the high water solubility of alcohols and ketones, the calibration criteria for these compounds is <30% RSD.The average % RSD of all compounds in the calibration is 15%, in accordance with EPA methods.

For GRO (C4-C12):

GRO (C4-C12) is quantitated against a gasoline standard. Quantitation begins immediately followine the methanol peak.

For Extractable Fuel Hydrocarbons (EFH, DRO, ORO) :

Unless otherwise noted, Extractable Fuel Hydrocarbons (EFH, DRO, ORO) are quantitated against a Diesel Fuel Standard.

DOMINGUEZ CHANNEL, SOUTH OF CARSON STREETCARSON, CALIFORNIA

Dear Mr, Crippen:

The California Regional Water Quality Control Board, Los Angeles Region (Regional Board) is thepublic agency with primary responsibility for the protection of groundwater and surface water quality forall beneficial uses within major portions of Los Angeles and Ventura counties, including the referencedSite. To accomplish this, the Regional Board oversees the investigation and cleanup of unregulateddischarges adversely affecting the State's water, authorized by the Porter-Cologne Water Quality ControlAct (California Water Code [CWC}, Division 7).

Since January 2011, light non - aqueous phase liquids (LNAPL) have been appearing within theDominguez Channel in Carson, California, approximately 400 feet south of Carson Street. Thepetroleum product has been observed (1) entering into channel waters from sediments within the bottomof the channel and (2) within horizontal, perforated sub-drain pipe .systeins installed within both the westand east channel levees.

This Regional Board has been working in collaboration with other agencies, under United States.Environmental Protection Agency (USEPA) lead, to facilitate the assessment and remedy of the release.As the channel owner and operator, the Los Angeles County Department of Public Works (LADPW) hasbeen performing containment operations using booms and absorbent pads in the channel. In addition tothe recovery of released product to channel waters, this Regional Board has requested that LADPWextract LNAP.L from the sub-drain piping systems on both sides of the channel.

Samples of product entering channel waters from sediments in the bottom of the channel have beendetermined to contain primarily gasoline-range hydrocarbons, with smaller fractions of heavier-end(diesel- and oil - .range) hydrocarbons. Product examined from the western sub-drain system was observedto be approximately 0.25 inch thick on one occasion with a clear and colorless appearance. Productexamined from the eastern sub-drain system was observed to be dark brown to black and translucent.Based upon the variation in the visual appearance of the product, this Regional Board suspects thatmultiple releases of petroleum may be involved. The sources of the release have not been identified.

Re: Requirement for Technical Report - Cal. Water Code§13267 OrderDo:minquez Channel, Carson, California

Dear Mr. :Unger:

1 write on behalf of Chevron, Texaco and Unocal in response to the April 2:6, 2011 order issued underWater Code section 13267 requiring these (and other) entities to prepare and submit a technical report forthe investigation of soil and groundwater in the vicinity of the Dominguez Channel in Carson, California(the "Order"). As set forth below, Chevron objects to the issuance of the Order as a violation of thereasonable relationship and full evidence requirements of Water Code section 13267.

Preliminarily, .1 wish to clarify the entities on behalf of whom Chevron is responding, and to provide youwith the proper contact people for each entity. The remediation of the former Texaco service stationlocated at 1209E, Carson Street is being managed by Chevron Environmental Management Company("CEMC") and you correctly identified Rob Speer as the point. of contact for that site, Chevron Pipe LineCompany is identified in the Order as a potentially responsible party ("PRP") for a.former Union OilPipeline. This is incorrect, although we. understand that Chevron may have caused this confusion giventhat Chevron Pipe.Line Company participated in the March meetings on behalf of CEMC. Chevron neveroperated the pipeline in question. To the extent it may be a Unocal :liability which we dispute, asdiscussed below it is a historic liability now managed by Chevron Environmental ManagementCompany. Please direct any future correspondence regarding this pipeline to Ben Terry at CEMC. Hemay be reached at Chevron Environmental Management Company, 6101 Bollinger Canyon Road, SanRamon, CA 94583. Mr. Terry's telephone nnmber is (925) 790-6240 and his email address [email protected].

With regard to the merits of the Order, we do not believe it properly complies with Water Code section13267. The statute requires that the burden, including costs, of any requirement to submit technical ormonitoring program reports shall bear a reasonable relationship to the need for the reports and the benefitsto be obtained from them. The Regional Board is further required to provide any party to whom such anorder is issued "with a written explanation with regard to the need for the reports and shall identify theevidence that supports requiring that person to provide the reports." Cal. Water Code § I 3267(b)(1).This Order does not sufficiently justify the costs of the report demanded nor does it provide adequateevidence for naming the Chevron-related entities.
