O P I N IO N AND ORDER T h is is a civil action brought by Jorge Francisco Sánchez and Dolores Service Station a n d Autoparts, Inc., hereinafter collectively referred to as "the Station," against Esso Standard O i l Company (Puerto Rico) ("Esso") under the citizen suit provision of the Resource C o n s e rv a t io n and Recovery Act ("RCRA"), 42 U.S.C. § 6972. The Station alleges that releases o f petroleum product from three underground storage tanks ("USTs"), formerly owned by Esso, c a u se d the contamination of soil and groundwater at and near the Station's property ("the p ro p e rty" ). The Station seeks injunctive relief and the imposition of civil penalties for alleged v io la tio n s of the Solid Waste Disposal Act (the "Act"), as amended by RCRA, 42 U.S.C. § § 6901-6992k, and Commonwealth and federal regulations governing notification and

c o r re c tiv e action requirements for releases from USTs.1 On August 5, 2009, we granted the S ta tio n 's oral motion for an evidentiary hearing to address the quality and reliability of a n a lytica l data generated in the parties' court-ordered, joint environmental site assessment (" E S A " ). (See Docket No. 154.) The evidentiary hearing commenced on September 17, 2009, a n d ended the same day. Also before the court are "Esso's Second Motion Seeking the Im p o si tio n of a Security Bond Pursuant to F.R.C.P. Rule 65(C)" ("Esso's Second Motion for S ec u rity") (see Docket Nos. 151 and 191), which Plaintiffs oppose (see Docket No. 166), and " E s so 's Motion in Limine as to Testimony of ERM's José Hernández" ("Esso's Motion in L im in e " ) (Docket No. 208), which Plaintiffs oppose (see Docket No. 213). Having thoroughly re v ie w e d the record and with particular consideration of testimony proffered at the S e p te m b e r 17, 2009, hearing, the court finds the data generated to date in the ESA to be valid a n d otherwise reliable.2

Any person who violates any requirement of subchapter III of the Solid Waste Disposal Act, 41 U.S.C. § 6901 et seq., as amended by RCRA, shall be liable to the United States for a civil penalty in an amount not to exceed $25,000 per violation, with each day constituting a separate violation. 42 U.S.C. § 6928(g). A federal district court may impose civil penalties authorized under section 6928(g) in RCRA citizen suits. See 42 U.S.C. 6972(a); Davis v. Sun Oil Co., 953 F.Supp. 890, 893 (S.D. Ohio 1996) ("§ 6972(a) permits the imposition of a civil penalty in an action brought by a private party"). As stated by Justice Blackmun in Daubert v. Merrell Pharmaceuticals, "in a case involving scientific evidence, evidentiary reliability will be based on scientific validity." 509 U.S. 579, 589 n.9 (1993) (emphasis supplied).

I. F a c tu a l and Procedural Background P la in tif f s' 0.77-acre parcel of property is located at Km. 14 of northbound highway PR-3 in the municipality of Canóvanas, Puerto Rico. The property is situated approximately thirtyf iv e feet above sea level and between 2,500 to 3,300 feet from the Río Grande de Loíza w a te rw a y,3 which flows into the Atlantic Ocean. The property has been used for the operation o f a gasoline-dispensing service station since the early 1960s. In 1985, Esso replaced Shell Oil as the gasoline and diesel supplier for Dolores Service S ta tio n . On or about the same date, Esso acquired ownership of three USTs located on the p ro p e rty, including two 10,000-gallon capacity, steel USTs used to store gasoline and one UST u s e d to store combustible diesel. Esso served as the supplier of gasoline and diesel for Dolores S e rv ic e Station until October 2008. At or about that time, Esso sold the three USTs. S in c e Esso became the supplier for Dolores Service Station in 1985, each of the three U S T s at the property has been removed and replaced at least once. In August 1992, Esso r e m o v e d and replaced the combustible diesel UST located in the southeast corner of the p r o p e r t y with a 6,000-gallon capacity, double-walled, fiberglass UST. (See Docket No. 24; P la in tif f s' Ex. No. 2.) In January 1998, Esso removed and replaced the two 10,000-gallon

c a p a c ity USTs located on the southwest corner of the property with two 12,000-gallon USTs. ( I d .) A. P r io r Site Assessments and Investigations4 T h e record in this case is replete with environmental investigations and monitoring a c tiv ity carried out at the property. To emphasize the significance of findings in the more recent c o u r t- o r d e re d ESA, we review the relevant findings and conclusions from historical in v e s tig a tio n s and monitoring activities. In February 1993, Esso commenced a monthly groundwater monitoring program at the p rop erty. The program incorporated three monitoring wells, two (MW-1, MW-2) located near th e combustible diesel tank and one (MW-3) located near the gasoline USTs. Monthly g ro u n d w a te r monitoring reports indicate that between February 1993 and December 1997, Esso o r its representative periodically measured organic vapor in the three wells at concentrations up to 32,000 ppm. The reports also indicate that Esso or its representative detected a dark film in M W -3 during the months of June, October, and December of 1995. There is no evidence in the re c o rd indicating what immediate action, if any, Esso took in response to these findings. There is also no evidence we could find in the record indicating when, if at all, Esso notified the P u e rto Rico Environmental Quality Board ("EQB") regarding these findings.

See plans detailing most of the well locations addressed in this opinion (Docket Nos. 150-4 and 152 (Figure 1)).

I n January and February 1998, Esso contracted Environmental Resources Technologies (" E R T E C " ) to evaluate the condition of subsurface soil following the removal of the two 1 0 ,0 0 0 - g a llo n USTs.5 ERTEC incorporated its findings and conclusions into a "Report on R e m o v a l of Underground Storage Tanks" ("Removal Report"), dated May 5, 1998. (See D o c k e t No. 24; Plaintiffs' Exhibit No. 2.) According to the Removal Report, ERTEC's e v a lu a tio n included an OVA field analysis for nine soil samples and laboratory analyses of eight b o r in g samples for the following constituents: Benzene, toluene, ethyl benzene, and xylenes (c o lle c tiv e ly, "BTEX"), and petroleum hydrocarbons in the gasoline range ("TPH-GRO"). O V A field analyses detected organic vapor in soil at concentrations between 3.8 and 37 ppm.6 E R T E C concluded that the organic vapor concentrations were below the 100 ppm limit e s ta b lis h e d as acceptable by the EQB. Laboratory analysis detected no concentration of BTEX o r TPH-GRO above detectable limits. Based on these results, ERTEC recommended that a d d itio n a l work not be carried out at the site. B y letter dated May 14, 1999, Marla Y. Rivera, Esso's Environmental Services S u p e rv is o r, advised Katherine Batista, then head of the EQB's Underground Tanks Program,

By letter dated June 6, 1997, Carlos I. Figueroa, then lead engineer in Esso's Environmental Section, informed Katherine Batista, then Director of the EQB's Underground Tanks Program, that it planned to replace the two gasoline USTs with two 12,000-gallon USTs with design features intended "to prevent contamination of the subsoil and possible leaks." Features enumerated in the letter included: "(1) overfill prevention equipment, (2) Veeder Root equipment for interstitial monitoring of the double fiberglass wall tank, slump riser, and dispenser area, and (3) "`Enviroflex' lines with primary and secondary system, . . . installed with a slope toward the tank's Slump Riser to collect any leakage of product in the lines." (See Defendant's Ex. No. 7.)

th a t based on the 1998 testing, "it is not necessary to carry out additional environmental work in the indicated area." (Docket No. 25; Defendant's Ex. No. 9.) In the same letter, Esso re q u e ste d an "environmental release" for the "tanks replacement area" (i.e., the gasoline UST are a). By letter dated August 31, 2001, Yvonne Santiago, then Director of the EQB's Water Q u a lity Division, granted Esso's request for an environmental release for the removal site, n o tin g that the 1998 testing results were, in fact, below regulatory limits. Under the terms of th e release, Esso was no longer obligated to conduct further environmental study at the removal s ite . (See Docket No. 25; Defendant's Ex. No. 10). In 2001, Esso contracted ERTEC to investigate the condition of soils in the vicinity of th e diesel UST. (See Docket No. 24; Defendant's Ex. No. 2.) ERTEC'S findings and c o n c lu s io n s from the investigation are incorporated into a report dated February 13, 2003. E R T E C 's investigation occurred on November 7 and 9, 2001, and required the collection of soil s a m p le s from four borings drilled on each side of the diesel UST.7 The results of an analytical ru n on those samples indicate the presence of petroleum hydrocarbons in the diesel range (" T P H -D R O " ) in each sample at concentrations ranging from 40 mg/kg to 3,290 mg/kg.8 Based o n these findings, ERTEC concluded that: (1) the concentrations of hydrocarbons in the subsoil w e re "above the criteria of cleanliness typically accepted by the Environmental Quality Board

ERTEC collected samples every two feet up to a depth of 18 to 20 feet below grade. OVA field analysis determined whether laboratory analysis would be requested.

(E Q B )" ; and (2) the contamination "can be connected to leaks coming from the system and tank lin e located to the east of the station or from the one previously replaced in 1992." (Docket N o . 24; Defendant's Ex. No. 2.) ERTEC recommended both integrity tests to the tank and d ie se l lines and "a risk base study . . . to identify the possible recipients at the site and to e v a lu a te the need, if any, to do additional work." (Id.) There is no evidence in the record in d ic a tin g when, if at all, Esso conducted the recommended integrity tests or surveyed possible recepto rs of subsurface contamination. However, the record does include a "Sensitive Receptive S u rv e y" ("SRS"), completed for the property on December 8, 2005.9 (See Docket No. 24; D ef en d an t's Ex. No. 4.) B y letter dated February 21, 2003, Marluz López, Esso's Remediation Coordinator, in f o rm e d Katherine Batista of the EQB that Esso would be carrying out an additional e n v iro n m e n ta l assessment at the diesel UST site to determine the extent of the hydrocarbon c o n ta m in a tio n and would be ready to submit a remediation plan with applicable alternatives if n e c e s s a ry. (See Docket No. 25; Defendant's Ex. No. 11.) There is no documentation in the re c ord to indicate that Esso completed an additional environmental assessment at the diesel UST s ite in 2003, 2004 or 2005.

The SRS inventoried information regarding potential receptors of hydrocarbon contamination, including, without limitation: (1) the presence of a regional aquifer located less than 20 feet below grade; (2) no municipal water wells located within 2,000 feet of the property; (3) no private water wells located within 1,000 feet of the property; (4) no utility vaults located on or adjacent to the property; (5) no surface bodies of water located within 1,000 feet of the property; (6) no storm water drains located on or adjacent to the site; (7) the presence of sanitary lines located on the southeast side of the facility and along PR-3. The nearest potable water extraction well, identified as Santa Bárbara (52-WW-03), would appear to be located approximately 3,300 feet north of the station, on the south side of the Río Grande de Loíza.

In September 2006, Esso contracted ERTEC to evaluate the condition of soil and g rou n d w ater at the property. ERTEC incorporated its findings and conclusions into a Phase II E n v iro n m e n tal Evaluation (the "Phase II Evaluation"), dated November 14, 2006. (Docket N o . 24; Plaintiff's Ex. No. 5.) ERTEC's evaluation required the drilling of eleven soil borings, f iv e of which were used for the installation of monitoring wells (MW-101, MW-102, MW-103, M W -1 0 4 , MW-105). Laboratory analyses were run on soil and groundwater samples for BTEX, T P H -G R O , TPH-DRO and TPH-oil. ERTEC's findings included: (1) aromatic hydrocarbon d e tec ted in six soil borings at concentrations ranging from non-detectable to 2,000 ppm; (2 ) TPH-GRO and TPH-DRO in two soil samples at concentrations of 5.4 ppm and 93 ppm, re s p e c tiv e ly;1 0 and (3) benzene in groundwater at concentrations measuring up to 2,800 ug/l (at M W -1 0 1 ). ERTEC concluded that the concentrations of TPH-GRO and TPH-DRO detected in soil were below the cleanliness criteria of 100 mg/kg typically accepted by the EQB, and that c o n c en tra tio n s of benzene in groundwater exceeded the federal drinking water standard of 5 u g /l. ERTEC also concluded that the groundwater contamination appeared to be related to re le a se s from the USTs and possibly releases from the grease traps located in the northeast area o f the property (See Docket No. 24; Plaintiffs' Ex. No. 5). Notwithstanding the Phase II E v a lu a tio n , by letter dated November 15, 2006, Carlos Figueroa, Esso's Remediation C o o rd in a to r, sought confirmation from Katherine Batista of the EQB that no additional e n v iro n m e n ta l activities needed to be completed at the site. In his letter, Mr. Figueroa requested

a n environmental release for the property. (See Docket No. 25; Defendant's Ex. No. 12.) T h e re is no indication in the record that Ms. Batista confirmed Mr. Figueroa's understanding o r granted his request for an environmental release. U n der cover dated November 27, 2007, Mr. Figueroa submitted a Corrective Action Plan (" C A P " )
11

to Ms. Batista. (See Docket No. 24; Plaintiffs' Ex. No. 6.)

The CAP's stated

o b jectiv e is "to determine the extent of the hydrocarbons dissolved in the underground water a n d to promote the reduction thereof through the application of the bio-remediation method k n o w n in English as ORC (Oxygen Release Compound)." (Id.) It is unknown whether the E Q B requested the CAP or whether Esso provided it of its own accord. There is no indication in the record that that the EQB ever approved Esso's proposed CAP. In May 2008, ERTEC conducted groundwater sampling in accordance with the CAP at f iv e existing wells (MW-101, MW-102, MW-103, MW-104, MW-105), which are located at th e southern end of the property. Monitoring results are incorporated into a "Progress Report," d a te d July 16, 2008. (See Docket No. 24; Defendant's Ex. No. 5.) Under cover dated A u g u s t 13, 2008, Esso submitted the Progress Report to Ms. Batista of the EQB. (See Docket N o . 25; Defendant's Ex. No. 14.) As detailed in the Progress Report, analytical results indicate th e presence of benzene in groundwater at concentrations ranging from non-detectable to 464 u g /l (at MW-101), a lower range of benzene concentration than what ERTEC detected in its

CAPs are submitted in accordance with Rule 607 of the Underground Tanks Regulation of the EQB, which provides, in part, "[t]he EQB will approve the corrective action plan only after ensuring that implementation of the plan will adequately protect human health and safety, and the environment."

Based on these findings, ERTEC identified two areas of

g ro u n d w a te r affected by hydrocarbon contamination, one in the northwest corner of the property (b y MW-102) and one situated east of the diesel UST (by MW-104). During the 2006 Phase I I Evaluation, ERTEC also measured several water quality indicators to assess the suitability o f ORC technology. (Docket No. 24; Plaintiffs' Ex. No. 5.) Finding conditions favorable for th e application of ORC technology, ERTEC installed mesh with the ORC compound in each o f the five monitoring wells following the May 2008 sampling. B. T h e Present Action T h e Station filed the present suit on October 6, 2008, under two causes of action. The S ta tio n 's first cause of action is based on alleged violations of the EQB's Underground Storage T a n k Regulations ("USTR"), see P.R. Admin. Regulation 4362 Rules 501, 503, 601, 602(A)(B ), 603(A), 604(A)-(B), and 606(A) (1) (3),1 3 and their federal counterparts, 40 C.F.R. §§
E.g., compare the 464 ug/l detected in the sample collected from MW-101 in 2008 to the 2,800 ug/l detected in MW-101 during the 2006 Phase II Evaluation. Rule 501 reads, in pertinent part, as follows: "Owners and operators must report to the Board within 24 hours, and follow the procedures in Rule 503 for any of the following conditions: A. The discovery by owners and operators or others of released regulated substances at the UST site or in the surrounding area (such as free product or vapors in soils, basements, sewer and utility lines, and nearby surface waters)." Rule 503 reads, in part, as follows: "Unless corrective action is initiated in accordance with Part VI, owners and operators must immediately investigate and confirm all suspected releases of regulated substances requiring reporting under Rule 501 within seven (7) days, using either the following steps or another procedure approved by the Board . . . ." Rule 601 reads as follows: "Owners and operators of petroleum or hazardous substances UST systems must, in response to a confirmed release from the UST systems must, in response to a confirmed release from the UST system, comply with the requirements of this Part except for UST's excluded under Rule 103(B) and UST systems subject to RCRA Subtitle C corrective action requirements under Section 3004(u) of the Resource Conservation and Recovery Act, as amended." Rule 602 reads as follows: "Upon confirmation of a release in accordance with Rule 503 or after a release from the UST system is identified in any other manner, owners and operators must perform the following

2 8 0 .5 0 , -.52, -.60 to -.63, and -.65 (2010). These regulations impose notification and corrective
initial response actions within 24 hours of a release. A. Report the release to the Board (e.g.) by telephone or electronic mail; B. Take immediate action to prevent any further releases of the regulated substance into the environment; and C. Identify and mitigate fire, explosion and vapor hazards." Rule 603 reads as follows: "A. Unless directed to do otherwise by the Board, owners and operators must perform the following abatement measures: 1- Remove as much of the regulated substance from the UST system as is necessary to prevent further release to the environment; 2- Visually inspect any above-ground releases or exposed below-ground releases and prevent further migration of the released substance into surrounding soils and groundwater; 3- Continue to monitor and mitigate any additional fire and safety hazards posed by vapors or free product that have migrated from the UST excavation zone and entered into subsurface structures (such as sewers and basements); 4- Remedy hazards posed by contaminated soils that are excavated or exposed as a result of release confirmation, site investigation, abatement, or corrective action activities. If these remedies include treatment or disposal of oils, the owner and operator must comply with all applicable Board and other local and federal agencies requirements; 5- Measure for the presence of a release where contamination is most likely to be present at the UST site, unless the presence and source of the release have been confirmed in accordance with the site check required by Rule 503(B) or the closure site assessment of Rule 703(A). In selecting sample types, sample locations, and measurement methods, the owner and operator must consider the nature of the stored substance, the type of backfill, depth to groundwater and other factors as appropriate for identifying the presence and source of the release. If these activities include drilling and installation of groundwater monitoring and or extraction wells, the owner and operator must comply with the procedures established by Law No. 136, of June 3, 1976 (Water Law of Puerto Rico) for the application of permits and franchises; and 6- Investigate to determine the possible presence of free product, and begin free product removals as soon as practicable and in accordance with Rule 605." Rule 604 reads as follows: "A. Unless directed to do otherwise by the EQB, owners and operators must assemble information about the site and the nature of the release, including information gained while confirming the release or completing the initial abatement measures in Rule 601 and Rule 602. This information must include, but is not necessarily limited to, the following: 1- Data on the nature and estimated quantity of release; 2- Data from available sources and/or site investigations concerning the following factors: surrounding populations, water quality, size and approximate locations of wells potentially affected by the release, subsurface soil conditions, locations of subsurface sewers, climatological conditions, and land use. 3- Results of the site check required under Rule 603(A)(5); and 4- Results of the free product investigations required under Rule 603 (A)(6), to be used by owner and operators to determine whether free product must be recovered under Rule 605. B. Within 45 days of release confirmation, owners and operators must submit the information collected in compliance with paragraph (A) of this Rule to the Board in a adequacy, or in a format and according to the schedule required by the Board." Rule 606 reads as follows: "A. In order to determine the full extent and location of soils contaminated by the release and the presence and concentrations of dissolved product contamination in the groundwater, owners and operators must conduct investigations of the release, release site, and the surrounding area possibly affected by the release if any of the following conditions exist: 1- There is evidence that groundwater wells have been affected by the release (e.g., as found during release confirmation or previous corrective action measures); 2- Free product is found to need recovery in compliance with Rule 605; 3- There is evidence that contaminated soils may be in contact with groundwater (e.g., as found during conduct of the initial response measures or investigations required under Rule 601 through 605); and 4- The EQB requests an investigation based on the potential effects of contaminated soil or groundwater on nearby surface water and groundwater resources. B. Owners and operators must submit the information collected under paragraph (A) of this Rule as soon as practicable or in accordance with a schedule established by the Board."

a c tio n requirements on owners and operators of USTs in the event of a suspected release. The S tatio n 's second cause of action is based on two alleged violations of the Solid Waste Disposal A c t, 42 U.S.C. 6901-6992k. First, the Station alleges that Esso "contributed to the generation, h a n d lin g , storage, treatment, transportation and disposal of solid or hazardous waste" in a m a n n e r that presents or may present a danger to human health and the environment in violation o f the Act. Second, the Station alleges that Esso has improperly stored and disposed of gasoline a n d diesel products at a non-permitted facility in violation of subchapter III of RCRA. As re m e d y, the Station requests, inter alia, that Esso be enjoined and restrained from causing any fu rth er release or discharge of hazardous waste and be compelled to comply with the abovelis t e d regulations and conduct all necessary testing and corrective action to remove and e lim in a te all pollution and contamination. O n December 5, 2008, we granted the Station's motion for injunctive relief, ordering the p a rtie s to undertake, at Esso's expense, a joint environmental site assessment ("ESA") to d e lin e a te the full extent of soil and groundwater contamination at and near Plaintiffs' property. (S e e Docket No. 22.) Pursuant to our order, the parties submitted written motions

re c o m m e n d in g persons and companies to perform the assessment. (See Docket Nos. 27; 29.) On December 22, 2008, we then ordered that the parties' comprehensive site assessment team (th e "team") would be composed of the consultant On-Site Environmental, Inc. ("On-Site"),

(See Docket Nos. 49; 50; 54.) We approved the parties' joint work plan and field a c tiv itie s to commence in February 2009. (See Docket No. 82-2.) The work plan requires the d rillin g of twelve soil borings and the installation of ten groundwater monitoring wells for the c o llec tio n of soil and groundwater samples to be analyzed for the following constituents: B en ze n e, toluene, ethylbenzene, and xylenes (collectively referred to as BTEX), Methyl tertb u tyl ether (MTBE), tetraethyl lead (TEL or "organic lead"), perchloroethene (PCE), t ri c h l o ro e th e n e (TCE), dichloroethene (DCE), lead (Pb), and total petroleum hydrocarbon (T P H ). (See Docket No. 54.) The work plan also requires the collection and analysis of g ro u n d w a te r samples from the five existing monitoring wells (MW-101, MW-102, MW-103, M W -1 0 4 , MW-105) which were constructed during the 2006 Phase II Evaluation.

A s agreed by Esso and the Station, ERM selected and contracted two laboratories to p ro v id e analytical services -- Columbia Analytical Services ("Columbia") and Friedman & B ru ya Laboratory ("Friedman"), hereinafter collectively referred to as "the labs." 1 7 Esso's c o n su lta n t, ERM, routed soil and groundwater samples to the labs from the field. Pursuant to th e parties' joint work plan, the labs were to use a specific EPA test method or, in certain cases, a choice of two EPA test methods, in their analysis of the aforementioned constituents. By way o f example, the joint work plan designates test method "EPA 8021A or 8260" to be used for the a n a lysis of TEL. (See Docket No. 54-2.) Esso's and the Station's findings and conclusions f ro m the joint ESA are incorporated into separate ESA reports, submitted to the court on July 24 a n d August 3, 2009, respectively. (See Docket Nos. 150-3; 152.) W h ile the parties engaged in field studies pursuant to our preliminary injunction order is s u e d on December 5, 2008, the First Circuit entertained an interlocutory appeal by Esso c h a lle n g in g that order (Docket No. 22). See Sánchez v. Esso Standard Oil Co. (P.R.), 572 F.3d 1 (1st Cir. 2009). In an opinion issued on June 19, 2009, the Court of Appeals upheld our m an d at o ry injunction for Esso to undertake an ESA at the Station. Id. at 20-21. Although p re lim in a ry injunctions should usually preserve the status quo, the First Circuit noted that "the s ta tu s quo in cases of potential environmental contamination is not a `condition of rest,' but one

` o f action which, if allowed to continue or proceed unchecked and unrestrained, will inflict s e rio u s irreparable injury.'" Id. at 21 (quoting United States v. Price, 688 F.2d 204, 212 (3d Cir. 1 9 8 2 )). The Court of Appeals "applaud[ed] . . . this sensible step" because of "legitimate c o n c ern s about the possibility of extensive environmental contamination and its health effects." Id . A t the same time, the First Circuit vacated a portion of our order that "reflect[ed] an im p ro p e r adjudication on the merits of the dispute," id., because we consolidated the p r e lim in a r y injunction hearing with the trial on the merits, there being doubt on the record as to whether fair clear notice of consolidation was afforded to Esso. The Court of Appeals then d ire c te d us to assess the admissibility of the results of the ESA under the relevant rules and to re c o n s id e r Esso's request for a security bond under Federal Rule of Civil Procedure 65(c). Id. a t 22. We duly heed the First Circuit's mandate and proceed to address these matters. C. E S A Findings and Recommendations We briefly note the parties' relevant findings, as reported by their respective consultants. E R M and On-Site report: (1) no free phase petroleum products (i.e., gasoline, diesel or oil) f o u n d in any well; (2) benzene in excess of the USEPA Primary Drinking Water Standard of 5 ug/l in groundwater samples from three wells (MW-102, MW-104, and MW-203);1 8 and

On-Site erroneously reports five samples with benzene concentrations in excess of the primary drinking water standard because it applies an incorrect EPA drinking water standard and includes a duplicate sample.

( 3 ) TPH in excess of the Puerto Rico EQB screening guideline in samples from two soil borings (M W -2 0 8 and MW-211). (See Docket Nos. 150-3; 152-3.) E R M reaches three conclusions of particular interest to the court. First, ERM attributes T P H contamination detected in MW-208 and MW-211, located on the northern end of the p ro p e rty, to a near-surface release of hydrocarbon related to the operation of an on-site m e c h a n ic a l shop. (See Docket No. 150-2 at 30.) Second, ERM informs the Court that benzene c o n ta m in a tio n in excess of the EPA Drinking Water Standard is localized in two areas of the p ro p e rty. (See Docket No. 150-3 at 28.) One area is centered on MW-102 at the northwest c o rn e r of the property. (Id.) The other area is in the vicinity of MW-203 and MW-104, near th e diesel UST. (Id.) Third, ERM attributes contamination detected at concentrations below P u e rto Rico soil screening guidelines or drinking water standards to sources other than the U S T s .1 9

See, e.g., TPH detected in soil at MW-203 (at levels below soil screening guidelines) is attributed to near surface releases associated with historical or current operations of petroleum USTs at the location and TPH detected in soil at MW-202 (at levels below soil screening guidelines) is attributed to releases associated with "historical or current operations of petroleum USTs once located south of and adjacent to the location" or hydrocarbon releases from the hydraulic lifts/car wash at the location (see Docket No. 150-3 at 31). Analytical results show MTBE, benzene, ethyl benzene, total lead, and DCE to be present in soil samples, but not at concentrations in excess of applicable soil screening levels. The trace levels of total lead detected in soil (at levels below soil screening guidelines) is attributed to fill material underlying the pavement. (See id. at 33.) Benzene and ethyl benzene detected in soil (at levels below soil screening guidelines) is attributed to station activities. (Id. at 32.) Analytical results also show ethyl benzene, toluene, xylene, total dissolved lead, DCE and TCE to be present in groundwater samples, but not at levels in excess of applicable USEPA drinking water standards. ERM informs the court that the concentration of total dissolved lead detected in groundwater is indicative of background levels associated with the leaching of minerals present in naturally-occurring unconsolidated soil. (See Docket No. 150-3 at 29.) ERM further informs the court that DCE and TCE in groundwater is likely from "former UIC septic tanks and/or the infiltration of degreaser contaminated car wash rinse water into the hydraulic lift system wastewater collection sumps." (Docket No. 150-3 at 30.)

In contrast to the ERM report, the On-Site report offers no opinion as to the probable o rig in of TPH contamination detected at MW-208 and MW-211 at concentrations in excess of P u erto Rico soil screening guidelines or the origin of contaminants in soil and groundwater d e te c te d below applicable standards and screening guidelines. E R M and On-Site estimate groundwater flow at approximately 17 to 21 feet below grade in a north-northeast direction towards the Rio Grande de Loiza,2 0 but estimate dramatically d if f ere n t groundwater flow velocities. ERM estimates groundwater velocity to be between .0 0 0 0 6 9 and 1.34 ft/day. In contrast, On-Site estimates groundwater velocity to be between 1.16 a n d 158.4 ft/day. (See Docket No. 152.) B o th On-Site and ERM agree that the site assessment should be expanded, but advocate f o r different approaches. ERM recommends the installation of two off-site monitoring wells d o w n -g ra d ie n t from wells MW-203 and MW-204 to further delineate the lateral extent of b e n z e n e groundwater contamination in the southeast corner of the property. (See Docket N o . 150-3 at 29.) ERM does not recommend an expansion of the assessment in a northerly directio n because analytical results for groundwater samples collected from wells located downg ra d ie n t and cross-gradient from MW-102 do not indicate that benzene contamination exists in tho se wells. Accordingly, ERM concludes that benzene contamination in the northwest corner

ERM and On-Site report different ranges for depth-to-groundwater at the property. ERM indicates that the groundwater table is 18 to 20 feet below grade (see Docket No. 150-3 at 16), while On-Site indicates that the groundwater table is 17 to 21 feet below grade (see Docket No. 152).

o f the property near MW-102 "represents the maximum distance that dissolved benzene m ig ra te d relative to the direction of groundwater flow and its apparent source area [area around M W -10 2 ]." (Docket No. 150-3 at 28.) B y contrast, On-Site takes the position that monitoring wells are not suitable for d e te rm in in g the extent of subsurface contamination at the property because soils in the area are n o t homogenous. Non-homogenous soils would, according to On-Site, create "different paths o f less resistance for the contamination in the groundwater to travel in a northerly direction," to w a rd the Río Grande de Loíza. (Docket No. 152 at 16.) Instead of additional monitoring w e lls , On-Site recommends using "Electrical Resistivity" and "Seismic Refraction" to d e te rm in e the extent of contamination that exists, if any, between the station and the Río Grande d e Loíza. (See Docket No. 217.) The estimated cost of such a project is between $200,000 and $ 2 5 0 ,0 0 0 . (See Docket No. 226.) On-Site further recommends that certain facility grease traps a n d oil/water separators, allegedly constructed by Esso, be removed to prevent the spread of c o n ta m in a tio n . (See Docket No. 152 at 25.) C. A lle g e d Deviations from Court-approved Work Plan and QAQC Protocols A s an exhibit to its ESA report, the Station submits a "Report on Deviations From Court A p p ro v e d Laboratory Procedures" (the "Deviations Report") (Docket No. 152-2), authored by th e Station's proffered expert, Carlos M. Belgodere-Pamies, P.G.2 1 The Deviations Report

alleg es that the labs departed from certain quality assurance and quality control ("QAQC") p r o to c o ls governing the collection and analysis of soil and groundwater, as well as deviations f ro m the court-approved joint work plan. During a status conference on August 5, 2009, the S ta tio n ' s counsel requested an evidentiary hearing to address the alleged deviations.2 2 To put th e issue to rest, and to ensure that further assessment of the property would be guided by re lia b le data, we granted the Station's request. (See Docket No. 154.) The evidentiary hearing c o m m e n c e d on September 17, 2009, and ended the same day. II. A lle g e d Deviations O n behalf of Esso, Mr. Belgodere raises three concerns with the analytical data provided b y Friedman and three concerns with the analytical data provided by Columbia. With respect to Friedman, Mr. Belgodere takes issue with: (1) the fact that Friedman did not use one of the E P A test methodologies approved by the court in the parties' joint work plan for TEL analysis; (2) the representation in Friedman's laboratory report that "the percent recover [sic] for

licensed geologist in the Commonwealth of Puerto Rico. In the early 1980s Mr. Belgodere carried out environmental soil investigations with the consulting firms of McClelland Engineers, Inc., Raba Kistner Consultants, Inc., and Terra Vac, Inc. He is a co-founder of the Environmental Support Laboratory, Inc., where he worked between 1988 and 1993 on the development of laboratory procedures to test soils and water for hydrocarbon content and speciation. The Station informs the court that it was unable to communicate with the labs regarding its concerns because "ERM, Esso's representative, had total control of the laboratory analyses and did not allow Dolores Technical Group to query both laboratories regarding reported equipment problems and modifications to the requested analysis procedures." (Docket No. 152 at 2.)

T e tra e th yl Lead (TEL) in the laboratory control samples were outside of control limits for 8082 w a te r analysis, . . . and that the reported concentrations should be considered estimates;"and (3 ) the quality or lack of TEL calibration chromatograms in the data provided by Friedman. W ith respect to Columbia, Mr. Belgodere takes issue with (1) the fact that custody seals were ap p are n tly torn or missing on four of the eight coolers used to transport soil and groundwater s a m p l e s to Columbia's laboratory; (2) an alleged failure by Columbia to calibrate its instruments to certain constituents of concern; and (3) toluene contamination in four field blank samples.2 3 B a se d on the issues enumerated above, Mr. Belgodere takes the position in the D e v ia tio n s Report that the "quality or absence of quality of the laboratory results provided by E ss o render the same unusable for the purposes ordered by the Court." (Docket No. 152-1 at 1 4 .) At the hearing, Mr. Belgodere recommended on behalf of Esso that all groundwater

s a m p le s should be collected and analyzed again and that soil contamination should be rea sses sed through electronic measurement as described earlier in this opinion. (See Docket N o . 226 at 48, 88-89.) H a v in g duly considered the arguments presented in Mr. Belgodere's Deviations report an d at the hearing, we do not find a sufficient basis at this time to invalidate and render u n re lia b le the analytical data provided by the labs. That said, we support any effort by the S ta tio n to conduct an independently-funded environmental assessment of TEL contamination

A "field blank" is a sample of analyte-free water that is transferred, at the sampling site, into a container for the purpose of distinguishing ambient contamination from actual sample contribution.

III. E sso ' s Second Motion for Security 2 4 E s s o moves the court for an order requiring Plaintiffs to provide security pursuant to F e d e ra l Rule of Civil Procedure 65(c) in the amount of $400,000. Rule 65(c) provides that " [ t]h e court may issue a preliminary injunction or a temporary restraining order only if the m o v a n t gives security in an amount that the court considers proper to pay the costs and damages s u s ta in e d by any party found to have been wrongfully enjoined or restrained." Otherwise put, s e c u rity places a plaintiff on notice of "the maximum extent of its potential liability, since the a m o u n t of the bond is the limit of the damages the defendant can obtain for a wrongful in ju n c tio n , . . . provided the plaintiff was acting in good faith." Global Naps, Inc. v. Verizon N e w England, Inc., 489 F.3d 13, 21 (citing Continuum Co. v. Incepts, Inc., 873 F.2d 801, 803 (5 th Cir. 1989)) (internal quotations omitted). A party is deemed to be wrongfully enjoined " w h e n it had a right all along to do what it was enjoined from doing," id., 489 F.3d at 22, or to
On December 5, 2008, we granted Plaintiffs' request for injunctive relief (see Docket No. 22), and Esso appealed (see Docket No. 47). On January 15, 2009, we denied Esso's motion for the provision of security pursuant to Rule 65(c). (See Docket No. 53.) In an opinion dated June 19, 2009, the Court of Appeals vacated, in part, the December 5, 2008, order and remanded with instructions for us to "reconsider Esso's request for a bond based on the requirements of Federal Rule 65(c)." (Docket No. 137.) Pursuant to the First Circuit's order, and with particular consideration of ESA results not previously before us, we now consider "Esso's Second Motion for Security."

n o t do what the court ordered it to do. Although the provision of security appears mandatory u n d e r Rule 65(c), the amount of security is "in such sum as the court deems proper." Fed. R. C iv . P. 65(c). T h e Station's basic argument in opposition to Esso's motion is that we should dispense w ith security all together or only require a nominal bond in light of the overarching public interest at issue in this case ­ protection of the public welfare and environment. Plaintiffs' a r g u m e n t is well-taken, but only in part. Plaintiffs' characterization of this case as "public in te re s t" litigation is on the mark. The public interest at issue here is undeniable.

C o n ta m in a tio n migrating off site and through the groundwater table in the direction of a public w a ter w a y is a serious matter of public concern. As recognized by the First Circuit in Crowley v . Local No. 82, Furniture & Piano Moving, there is a trend in "public interest" litigation to only re q u ire nominal security or to completely dispense with the security requirement. 679 F.2d 978, 9 9 9 -10 0 0 (1 st Cir. 1982), rev'd on other grounds, 467 U.S. 526 ("Rule 65(c) has spawned e ss e n tia ll y two lines of cases . . . . In the second line, no bond is required in suits to enforce im p o rta n t federal rights or public interests."). Plaintiffs, however, misconstrue Crowley to the e x te n t they ask us to apply a blanket exception to the security requirement because this case c o n c e rn s an issue of public interest. That is not the law. There are circumstances that often, b u t not always, arise in public interest litigation which weigh against imposing a substantial s e c u rity requirement. It is a case-specific inquiry governed by the three-part test articulated in C r o w le y : (1) "the possible loss to the enjoined party together with the hardship that a bond

Civil No. 08-2151 (JAF)

re q u ire m e n t would impose on the applicant"; (2) "the impact that a bond requirement would h a v e on the enforcement of a federal right"; and (3) whether the likelihood of success on the m e rits of the claims at issue is extraordinarily high, which would weigh against a substantial b o n d requirement. Id. at 1000. W ith respect to the first factor, if it is determined that Esso has been wrongfully enjoined in this case, Esso may be damaged in an amount approximating the cost of the assessment. To d a te, Esso has been invoiced for services rendered by ERM and On-Site in an amount a p p ro x im a tin g $300,900 (see Docket Nos. 59-3; 98-2; 98-3; 100-2; 110-2; 129-2; 129-3; 151-2; 2 4 9 ), and estimates that an additional $100,000 "should be sufficient to cover any conceivable a d d itio n a l investigative work" (Docket No. 151 at 5). The Station makes no representation that a bond requirement would pose a significant financial burden or hardship. See, e.g., Westfield H ig h Sch. L.I.F.E. Club v. City of Westfield, 249 F.Supp.2d 98, 128 (D. Mass. 2003) (declining to impose security requirement after finding no evidence of possible loss to the enjoined party a n d receiving affidavits indicating plaintiff's financial inability to post security); People ex rel. V a n De Kamp v. Tahoe Reg'l Planning Agency, 766 F.2d 1319, 1325 (9 th Cir. 1985) (affirming d e c is io n to not require payment of security by a non-profit environmental group to cover p o te n tia l property damage after the group indicated that it was unable to pay the requested s e c u rity). The Station makes no effort to establish that it would be significantly burdened by a security requirement. We, therefore, must conclude that the security requested would not p re s e n t a significant financial hardship.

Civil No. 08-2151 (JAF)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

With respect to the second factor, as already noted, the Station provides no indication th a t it is unable to provide the requested security. As such, there is no basis upon which to co n clud e that a security requirement would foreclose plaintiffs' opportunity to pursue their R C R A claims. See, e.g., Natural Res. Def. Council v. Morton, 337 F.Supp. 167 (D. D.C. 1971), a ff'd on other grounds, 458 F.2d 827 (D.C. Cir. 1972) (setting $100 bond where security re q u e s te d "would have the effect of denying three nonprofit environmental organizations from o b ta in in g judicial review under NEPA"). L a stly, we consider whether there is a substantial likelihood that Plaintiffs will prevail o n the merits of their claims. We properly limit the scope of our inquiry here to alleged v io latio n s of administrative regulations that require owners and operators of USTs to conduct s it e investigations, such as the ESA. Rule 605 requires owners and operators to conduct in v e s tig a tio n s of a release site and the "surrounding area possibly affected" if there is "any e v id e n c e that contaminated soils may be in contact with groundwater" in order to determine the " f u ll extent and location of soils contaminated by the release and the presence and c o n c e n tra tio n s of dissolved product contamination in the groundwater." 2 5 In 2001, ERTEC c o lle c te d soil samples at depths between ten and twenty feet below grade that contained c o n c en tra tio n s of TPH-DRO as high as 3,290 mg/kg. Given the proximity of these samples to th e water table (18 to 20 feet below grade), we find that overwhelming evidence existed in 2001 th a t contaminated soils might be in contact with groundwater. Yet, it is not until now, almost

a decade later, that the full extent and location of groundwater contamination by benzene has c o m e to light. We recognize that, in 2006, Esso conducted an extensive Phase II Evaluation, b u t that evaluation did not fully determine the extent of benzene contamination in groundwater to the north of the USTs and in the southeast corner of the property or include lead as a c o n s titu e n t of concern. (See Docket No. 22.) It is, therefore, reasonable to conclude that prior to the court-ordered ESA, Esso had not fulfilled its obligation to fully delineate the extent of g ro u n d w a t e r and soil contamination on the property and surrounding areas, as is required by R u le 606. In consideration of the record before us at this time, it is unlikely that Esso has been w ro n g f u ll y enjoined. To the contrary, there is a substantial likelihood that the Station will p re v a il on a claim that Esso failed to meet the requirements of Rule 606. Having weighed the a b o v e Crowley factors, we find it appropriate at this time to impose a security requirement on th e Station in the amount of $100,000. IV . C o n c lu s io n F o r the reasons expressed above, we find at this time that the data generated to date in th e parties' court-ordered ESA to be both valid and reliable. The Station's oral motion to e x c lu d e such data from the ESA and from further consideration in this proceeding is hereby D E N I E D . Esso's Second Motion for Security (Docket No. 151) is GRANTED IN PART, and E s s o 's Motion in Limine (Docket No. 208), is DENIED AS MOOT.
