Long-Term Ground Water Monitoring Work Plan

BACKGROUND INFORMATION

Site Location and Access

The Bloomfield Refinery (the Refinery) is located south of Bloomfield, New Mexico, in San Juan County, latitude N36° 41' 87", longitude W107° 58' 70". The Refinery is owned by the San Juan Refining Company(SJRC). The Refinery Site (the site) consists of the Refinery processing areas, storage tanks, and waste management areas, as well as adjacent areas that exhibit subsurface petroleum hydrocarbons. Previously installed monitor wells define an area south of the Refinery where petroleum hydrocarbons are present in the subsurface, and the San Juan River defines the northern boundary of the site.

The Refinery is located on a bluff 120 feet above the south side of the San Juan River. The top of the bluff is relatively flat and is at an elevation of 5,540 feet above sea level. The geologic units that comprise the site include, in order of increasing depth, San Juan River Alluvium, Quaternary apron deposits, Aeolian sand and silt, Jackson'Lake Terrace, and the Tertiary Nacimiento Formation. An unnamed arroyo flows toward the San Juan River on the southern and western edges of the site. East of the site, a well-defined arroyo cuts a small canyon from the bluff to the San Juan River. Hammond Ditch, a newly concrete-lined irrigation ditch underlain by French Drain with a liquid recovery system, lies on the bluff between the limit of the Jackson Lake Terrace (also called the Nacimiento Cliff in this document) and the Refinery.

Site Description and History

Refinery offices are on the western end of the facility, along with warehouse space, maintenance areas, raw water ponds for temporary storage of fresh water from the San Juan River, and one storage yard containing used material (e.g., pipe, valves). Petroleum processing units, located in the northwest portion of the Refinery, include the crude unit, fluidized catalytic cracking unit, catalytic polymerization unit, and hydrodesulfurization unit. Several product storage tanks are present east of the petroleum processing area. The API separator is located in the northwestern portion of the site. The aeration lagoons, formerly known as the north oily water pond (NOWP), the south oily water pond (SOWP), and a part of the API system, were identified by the U.S. Environmental Protection Agency (EPA) as potential Resource Conservation and Recovery Act (RCRA) hazardous waste management units.

In the central portion of the site, aboveground storage tanks (ASTs) occupy a large percentage of Refinery property. South of the Refinery and across Sullivan Road are terminals for loading product and off-loading crude, as well as gas storage and hazardous waste storage.

The eastern portion of the site contains closed and operational wastewater treatment facilities. Until the end of 1994, two clay-lined evaporation ponds and a spray irrigation area were used to treat and dispose of process wastewater. Since that time, two double-lined 5-acre evaporation ponds and a Class I underground injection well have been used to manage all Refinery process wastewater. In late 1998, the former evaporation ponds were converted into new raw water ponds. The spray irrigation area was decommissioned in 1994 with the start up of the Class 1 injection well. It has been overlaid by a parking lot and office complex. The fire training area and the landfill are also located at the eastern end of the facility.

2

Wells south ofthe Refinery fence line and west of the crude unloading and product loading area define an area where petroleum hydrocarbons are present in the groundwater. The U.S. Bureau of Land Management (BLM) controls this part of the area. Subsurface hydrocarbons, including both dissolved-phase and separate-phase hydrocarbons, also are present north and west of the processing area, between the San Juan River and the cliff that defines the limit of the Jackson Lake Terrace deposits. This area is owned by SJRC.

The historical and current activities conducted at the Refinery include:

• Petroleum processing

• Crude and product storage

• Crude unloading and product loading

• Waste management (closed units and existing facilities)

• Offices and non-petroleum material storage

Local entrepreneur Kimball Campbell originally constructed the facility as a crude topping unit in the late 1950s. O.L. Garretson bought the facility in the early 1960s, renamed it Plateau, Inc., and sold it in 1964 to Suburban Propane of New Jersey. As a protective filing, Plateau applied for a RCRA Part A Permit as a generator of hazardous waste and as a treatment, storage, and disposal (TSD) facility in November 1980. In 1982, Plateau petitioned for reclassification under a generator-only status. Bloomfield Refining Company (BRC) acquired the facility from Suburban Propane (Plateau) on October 31, 1984. Facility ownership was transferred to SJRC on October 4, 1995.

SAMPLING PLAN

The objective of the Work Plan is to determine the status of the hydrocarbon plume, contain the plume, and ultimately reduce the plume.

Containment has been implemented by installing a hydraulic barrier at the San Juan River. Hydrocarbon recovery wil l be accomplished by utilizing numerous recovery wells, and the Hammond Ditch French Drain Recovery System. Reduction of the plume can be attained through proper operation of Giant's recovery well system as well as applying source control measures such as below grade line testing, practicing good housekeeping and updating plant employees' environmental awareness training.

RECOVERY AND MONITORING WELLS

Several changes wil l occur in the recovery well system in 2003. Fluid recovery wi l l be concentrated in the central portion of the site, which could potentially adjust the ground water flow and pull the plume back into the center of the site. This will be accomplished with the following changes:

• Recovery Wells #23 and #22 wil l utilize total fluids pumps. • Recovery Wells #19 and #17 wil l utilize total fluids pumps. • Monitoring Wells #28 and #9 wil l be converted into recovery wells. • MW #28 will become RW #28 (name change) and wil l be equipped with a

skimmer pump.

3

• MW #9 will become RW #9 (name change) and will be equipped with a total fluids pump.

• RW #2 will use a skimmer pump.

New Monitoring Wells and Modifications

Giant installed three new monitoring wells in January 2003, MW #45, and MW #46 (see attached map). Both wells are located down gradient of the Hammond Ditch.

Seep #5 was drilled west of Hammond Ditch but east of its original location. The gravel company will be mining the original location of Seep #5, so we moved it out of the arroyo and next to the dirt road along Hammond Ditch. Seep #5 was completed as a monitoring well, and will become MW#47 (name change). Giant has enclosed Installation diagrams for MW #45, MW #46, and MW #47.

An attempt was made to drill a background well east of the Refinery property but was a dry hole. Giant proposes to use MW #32 as a background well. MW#32 was sampled extensively and should prove to be a representative background well. Giant has enclosed laboratory analysis for MW#32. It is up gradient from all wells on the south side of Sullivan Road except for MW#5(dry) and MW#6(dry) and MW# 13 (drilled and screened through the Naciemento). It is cross gradient from the Terminals, but not in the flow path of any possible contaminants from that location.

Monitoring and Analysis

Giant's philosophy for monitoring and analysis is to focus on the hydrocarbon nature of the contamination. The long term sampling program will consist of sampling and analyzing wells located beyond the boundary of the containment zone and focusing on key points of compliance and assessment.

• Giant will measure the water table and product elevations in all facility monitoring wells on a semi-annual basis. The water/product levels will be measured to an accuracy of 0.01 foot. Adding 0.8 times the measured product thickness to the calculated water table elevation will provide a corrected water table elevation in wells containing separate phase hydrocarbons. All recovery wells will have pumps shut off and removed 24 hours prior to elevation measurements.

• Giant will collect groundwater samples on a semi-annual basis from wells MW #1, MW #6, MW #12, MW #13, MW #20, MW #24, MW #32, MW #33, MW #35, MW #37, MW #38, MW #45, MW #46, Seep #5(reconstructed and renamed

4

MW #47), P-#4, P-#5, and East Outfalls #1, #2, and #3 for 2003. The samples will be analyzed for BTEX and MTBE.

In September 2003 Giant will collect groundwater samples from the wells listed above as well as MW #3, MW #4, MW #5, MW #8 MW #26, MW #27, MW #34, MW #36 for a period of two years. For 2003,Giant will submit the ground water samples collected to an analytical laboratory for chemical analysis of VOC's by Method 8260, BTEX, MTBE, TDS and major cations and anions, dissolved WQCC metals, total and dissolved chromium and lead, nitrate/ nitrite, sulfate, dissolved oxygen, carbon dioxide and oxidation-reduction potential, pH, electrical conductivity, and temperature.

Method 8260 should prove that the contaminants are fuel-related constituents only. If that is the case, then Giant will collect and sample from wells MW #1, MW #3, MW #8, MW #4, MW #32, MW #35, MW #36, MW #12, MW #27, MW #47(Seep #5), MW #39, P-4, P-5. These samples will be analyzed for BTEX, MTBE, dissolved oxygen, oxidation-reduction potential, dissolved metals (Pb, Mn, Cr, and Fe only), sulfate, nitrate/nitrite, TDS, pH, electrical conductance, and temperature on a semi-annual basis starting in 2004.

Hammond Ditch East Outfalls #1, #2, and #3 will be sampled and analyzed for BTEX and MTBE on a semi-annual basis.

The wells will be purged prior to sample collection. Electrical conductance, pH, and temperature will be monitored during purging. The wells will be considered satisfactorily purged when the pH, E.C, and temperature values do not vary by more than 10 percent for at least three measurements, and at least three well casing volumes of water have been removed from the well. Purge water will be collected and disposed of through the refinery wastewater treatment system.

Recovery wells will not be sampled since they will give a distorted result. The purpose of the recovery well is negated if the well is shut down for the appropriate length of time needed to get a representative sample. Therefore, RW#15, RW#18, RW#23, RW#28, RW#42, RW #9, RW #1 and RW#43 will be not be sampled.

Wells that contain free product will not be sampled.

Annual Report

Giant will compile an annual comprehensive ground water monitoring report on all investigation, remediation, and monitoring activities. The report will be submitted to the NMOCD Santa Fe Office, NMOCD Aztec District Office, NMED Hazardous Waste Bureau, and the EPA by April 15 of each respective year. The annual report will include:

• A description of all soil and ground water remediation and monitoring activities that occurred during the previous calendar year.

• Annual water table potentiometric surface maps showing well locations, corrected water table elevations, pertinent site features, the direction of ground water flow and the hydraulic gradient.

• Semi-annual product thickness maps showing well locations, measured product thickness in each well and pertinent site features.

• Summary tables of all soil and ground water quality sampling results during the past calendar year and copies ofthe laboratory analytical reports and associated QA/QC data for the reporting period.

• Annual BTEX concentration maps indicating the concentrations detected at the sampled monitoring wells.

• Estimated volume of fluids recovered from each recovery well and the Hammond Ditch French Drain Recovery System.

• Concentration versus time plots of BTEX and MTBE.

• The disposition of all wastes generated.

• The results of any below grade line testing.
