2.0 SITE DESCRIPTION
The Dowell facility is located at 3106 Bloomington Highway in Farmington, New
Mexico. A site plan of the facility is shown on Figure 2-1.
The Dowell facility provides services for oil and gas production wells. Services include
well cementing, acidizing/stimulating and formation fracturing.

3.0 COLLECTION SYSTEMS
The following sections detail the collection systems at the Dowell, Farmington facility
which will be closed under this plan.
3.1 Truck Wash Bavs and Separator System
The truck wash bays and oil/water separator system are located in the central portion of
the facility (Figure 3-1). The system is comprised of two former truck wash bays, one inside
the maintenance building and the other just north of the building. Neither bay is in use. The
interior and exterior wash bay collection sumps are still intact and are connected to the separator
tanks by a six-inch drain line (Figure 3-1). The line from the separator to the sanitary sewer
line has been capped.
3.2 Loading Dock and Collection Sumo
The loading dock and collection sump are located in the north central portion of the
facility (Figure 3-2). The collection sump formerly received stormwater and incidental spills
from the former acid plant. The collection sump is surrounded by a concrete pad (Figure 3-2).
The entire acid plant has been out of service since May 1993.

4.0 PROPOSED CLOSURE ACTIVITIES
Closure of the two systems will be in accordance with Discharge Plan GW-100 which
was approved by the New Mexico Oil Conservation Division (NMOCD) August 1992. Both the
truck wash bays and separator system as well as the loading dock collection sump will be subject
to the following proposed closure activities.
4.1 Wastewater and Shidge
Composite samples of the wastewater and sludge remaining in the wash bay sumps and
separator tanks system were collected by Western Water Consultants, Inc. (WWC) of Laramie,
Wyoming on September 29,1993. The samples were designated 924-sep-west and 924-sep-east.
Samples were sent to Cenref Laboratories of Brighton, Colorado for analysis by Toxicity
Characteristic Leaching Procedure (TCLP) for volatile organics and metals. Total petroleum
hydrocarbons (TPH), representing the diesel range, were also part of the analysis in anticipation
of disposal requirements. Results of the analysis are illustrated on Table 4-1. The laboratory
reports are contained in Appendix A. All analytical work confirmed that the sump and separator
contents are non-hazardous. The loading dock collection sump is silted in, thus no samples were
collected.
Wastewater in the collection sumps and separator at the time of closure will be evacuated
and disposed at the Southwest Inc. Disposal facility of Blanco, New Mexico. Sludge in the
collection sumps and separator will be evacuated and placed on plastic sheeting within a

temporary revetment constructed in the northern portion of the facility. This material will be
incorporated with material described in Section 4.3 and characterized for disposal.
4.2 Separators. Collection Sumps, and Loading Dock
Once the wastewater and sludge are removed from the interior wash bay collection sump
the integrity of the sump will be inspected. If no cracks or defects are noted, the sump will be
filled with concrete and considered a "clean closure". If defects are noted, the interior wash
bay sump will be removed and the area excavated similar to the closure activities described
below for the other structures.
Excavation and removal from the ground of the separator and collection sumps will occur
following the removal of the wastewater and sludge. The concrete pads of the exterior truck
wash bay and loading dock will be lifted from the ground surface. The separator and concrete
pieces will be cleaned onsite to remove debris adhering to them. Removed debris will be placed
in the plastic lined temporary revetment. This material, also will be characterized for disposal
by laboratory analysis as stated in the following section. Once clean, the separator tanks will
be demolished. The tank and concrete pieces will be transported and disposed in the local
landfill.
4.3 Surrounding and Subsoil Excavation
After removal of the separator, sumps, and slabs from the ground, the soils underlying
and surrounding the excavations will be field-screened by headspace analysis with an
9
Environmental Instruments 580D Photoionization Detector to detect possible contaminants in the
soil.
If no contaminants are detected in the soil headspace from the samples immediately
beneath and surrounding the excavations, removal of the separator, collection sumps, and slabs
will be considered "clean closure". The excavations will be backfilled with clean fill, imported
from off-site.
If contaminants are detected in the soil headspace from the samples immediately beneath
and/or surrounding the former separator and/or sumps, such soils will be removed. Removal
activities will attempt to remove all contaminated soil but must be limited due to the presence
of nearby structures. Removal activities will be limited to 5 feet surrounding the initial
excavation of the tanks and sumps where possible and no greater than 5 feet below the tanks and
sump bottoms. Less material will be removed if justified by field screening.
Excavated soils will be placed in the plastic lined temporary revetment. One composite
sample will be collected from the soils pile for laboratory analysis to determine appropriate
disposal. The soil sample will be composited from five samples collected from random locations
within the interior of the pile. The composite sample will be analyzed by TCLP for volatile
organic compounds and metals; TPH by modified method 8015 (diesel range).
Effectiveness of the excavations will be confirmed by laboratory analysis of composite
soil samples from each of the excavations. The samples from each excavation will be collected
from a minimum of five separate in-place locations in the excavations. The soil samples will
be analyzed by TCLP for volatile organic compounds and metals; TPH by modified method
10
8015 (diesel range). If no contaminants are detected, the excavations will be considered "clean
closures".
4.4 Reclamation
The excavations will be filled to the surrounding surface by importing clean fill. The fill
will be emplaced in 6-inch lifts and compacted. An asphalt pad will be placed over the area of
the former exterior wash bay and interior wash bay if needed. The loading dock and collection
sump may be replaced as part of the construction of a new acid plant at the facility which will
occur under a separate project. All plans and specifications for a new facility will be submitted
to NMOCD for approval prior to beginning construction.
