ADMINISTRATIVE ORDER BY CONSENT
(Pursuant to
Rule 522.b.(3) of
the Rules and Regulations of the
Colorado Oil and
Gas Conservation Commission, 2 CCR 404-1)
FINDINGS
1.
Prior to July 27, 2007, OXY USA WTP LP, Operator #66571, (hereinafter referred
to as “OXY”) constructed the OXY 697-09-61 well pad (the “Well Pad”), which is
located in the SW¼ SE¼ of Section 9, Township 6 South, Range 97 West, 6th
P.M. (refer to Attachment 1). As originally constructed, the Well Pad included
an unlined drilling pit, which measured approximately 80 feet long, 50 feet wide
and 12 feet deep with a capacity of approximately 4,000 barrels with two feet of
freeboard. At various times, the Director (“Director”) of the Colorado Oil and
Gas Conservation Commission (“Commission” or “COGCC”) approved twenty-two (22)
Applications for Permit-to-Drill, Form 2s, for various bottomhole locations to
be drilled from the Well Pad.
2.
On
July 27, 2007, OXY spud the Cascade Creek #697-9-60D Well (API No. 05-045-14298)
and on September 6, 2007, OXY spud the Cascade Creek #697-09-52B Well (API No.
05-045-14445) (referred to collectively as the “Wells”) with both wells drilled
and placed on production from the Well Pad.
3. In
preparation for additional drilling from the Well Pad, on May 6, 2008, OXY
shut-in the Wells, and, subsequently, constructed an extension to the drilling
pit, which measured approximately 30 feet long, 20 feet wide, and 10 feet deep
with an additional capacity of approximately 800 barrels with two feet of
freeboard. After excavating the extension, OXY lined both the original drilling
pit and the extended drilling pit with a 36 mil liner underlain with a
geo-synthetic layer. On June 11, 2008, OXY temporarily abandoned the Wells by
placing subsurface plugs within the wellbores.
4. There are
two springs, one located in Section 9 and one located in Section 16, Township 6
South, Range 97 West, 6th P.M., which are located approximately 630
feet southwest and downgrade of the location of the unlined production pit on
the Well Pad (refer to Attachment 1). For purposes of this Administrative Order
by Consent (“AOC”), the northernmost spring is referred to as the “North Spring”
or “N Spring” and the southernmost spring is referred to as the “South Spring”.
These springs and a number of other smaller ground water seeps discharge from an
approximately 1,000 foot long stretch along the eastern bank of the unnamed
tributary. The spring waters discharge from the eastern bank of and into an
unnamed tributary which, in turn, joins Cascade Canyon in Section 16, Township 6
South, Range 97 West, 6th P.M. (refer to Attachment 1). Impacts to
the springs on the eastern bank, the unnamed tributary, and Cascade Canyon are
the subject of this AOC.
5. In addition
to North and South Springs, there is also an improved spring that supplies water
to OXY’s private cabin (locally known as Conn Camp (refer to Attachment 2))
which is sometimes used for livestock watering. The improved spring is known
locally as Conn Camp Spring and is located in Section 9, Township 6 South, Range
97 West, 6th P.M. Conn Camp Spring discharges from the western bank
of and into the unnamed tributary (refer to Attachments 1, 3, and 4). Conn Camp
Spring has not been impacted by the releases of exploration and production
(“E&P”) wastes that are the subject of this AOC.
6. The Well
Pad is immediately adjacent to an area that has been designated as sensitive
wildlife habitat by the Colorado Division of Wildlife for the benefit of the
greater sage grouse.
7. Water
produced in association with hydrocarbons (“produced water”) and condensate from
the Wells were placed in the unlined drilling pit located on the Well Pad – the
pit was placed into operation at or around the date of first completion (October
24, 2007). The extended portion of the original drilling pit on the Well Pad
was used as an unpermitted and unlined production pit from the date of well
completion until May 6, 2008 when the Wells were shut-in (refer to Attachment
5). Before constructing the pit or discharging produced water into it, OXY did
not submit a sensitive area determination to evaluate the potential for ground
water impacts.
a. Pre-April
1, 2009 rules (2 CCR 404-1, “Rules” or individually, “Rule”), that were in
effect when the production pit on the Well Pad was constructed, required
operators of production pits “to make a sensitive area determination . . . to
evaluate the potential for impact to ground water and submit [the] data
evaluated and analysis used in the determination to the Director” (former Rule
901.e.(2)). The submittal of this information to the Director allowed the COGCC
to evaluate whether a proposed production pit would be sited in an area
vulnerable to groundwater impact, and, if so, whether special precautions were
needed to avoid such an impact.
b. The Rules
further required production pits in sensitive areas to be permitted before
construction (former Rule 903.a.(1)B.).
c. During
this period of time the Rules defined sensitive area as “an area vulnerable to
potential significant adverse groundwater impacts, due to factors such as the
presence of shallow economically usable groundwater or pathways for
communication with deeper economically usable groundwater; proximity to surface
water, including lakes, rivers, perennial or intermittent streams, creeks,
irrigation canals, and wetlands.” 100-Series Rules.
d. The
production pit on the Well Pad was located in an area vulnerable to potential
significant adverse ground water impacts, and therefore it was located in a
sensitive area based on the following criteria:
i.
The production pit was
located in close proximity (approximately 630 feet) to the Conn Camp Spring, the
North Spring and the South Spring, and these springs are sources of water for an
unnamed intermittent tributary to Cascade Canyon, which is a perennial stream.
ii. Shallow groundwater was
impacted by a release of produced water and condensate from a pit, which
indicates that pathways for communication between the ground surface and
groundwater exist.
iii. The water discharged at the
North and South Springs is shallow economically usable groundwater, which was
used by ranchers for watering livestock and by wildlife.
iv. The water discharged at the
Conn Camp Spring is shallow economically usable groundwater, which is used by
ranchers for domestic purposes and watering livestock, and by wildlife. Conn
Camp Spring was not impacted by this release, but is located approximately 700
feet from and downhill of the Well Pad.
e. The
permitting of pits is an essential component of the COGCC regulatory scheme to
ensure best management practices are used by operators to protect public health,
safety, and welfare and the environment, including soil, waters of the state,
and wildlife, from significant adverse environmental, public health, or welfare
impacts from E&P waste. If this pit had been permitted, COGCC Staff assert
that they would have required OXY to line it and if the pit had been properly
lined and maintained releases of produced water and condensate would have been
far less likely to occur and the risk of impacts to ground water would have been
greatly reduced.
8. On June 16,
2008, OXY notified COGCC Staff of the potential contamination of water
discharging from natural springs and entering an unnamed intermittent tributary
of upper Cascade Canyon, located in Section 16, Township 6 South, Range 97 West,
6th P.M. Following the notification, OXY immediately initiated
mitigation measures by installing two dams (refer to Attachments 6, 7, 8, and 9)
to contain all flow from the unnamed tributary. Dam 1 was located downstream
of the North Spring in the vicinity of the Conn Camp corral. Dam 2 was located
on the unnamed tributary, just upstream of the confluence with Cascade Canyon.
Cascade Canyon drainage showed no evidence of contamination. Piping and pumps
were installed and water was pumped to the lined pit on the Well Pad referred to
in Finding No. 3.
9. On June 17,
2008, OXY installed a series of hydrocarbon absorbing booms and straw bales in
the unnamed tributary and in Cascade Canyon below the confluence with the
unnamed tributary. In all, approximately ½-mile of the unnamed tributary was
impacted by direct discharge of contaminated ground water.
10. On June 17,
2008, COGCC Staff inspected the impacted springs, surface water, the Well Pad,
and production pit. It was observed that condensate was discharging from the
North and South Springs (refer to Attachment 11) and the presence of an
associated sheen on the water flowing in the unnamed tributary. In addition,
hydrocarbon stained soil and rock were observed in the bottom of a portion of
the original drilling pit (refer to Attachment 5).
11.
On
June 18, 2008, at COGCC’s request, OXY constructed two interceptor trenches
(referred to as the N Interceptor Trench (refer to Attachment 12), located
between the Well Pad and near the North Spring, and the S1 Interceptor Trench
(refer to Attachment 13), located between the Well Pad and near the South Spring
(refer to Attachment 6)) to restrict the flow of contaminants to the unnamed
tributary. COGCC Staff collected water samples from the Conn Camp cabin kitchen
faucet, the Conn Camp Spring, and the South Spring. Benzene, toluene,
ethylbenzene, and xylenes (referred to collectively as “BTEX”) were not detected
in samples from the kitchen faucet in the Conn Camp cabin or spring, however,
benzene was detected in the water sample collected from the South Spring at
concentrations which exceeded Colorado Department of Public Health and
Environment (“CDPHE”) Water Quality Control Commission (“WQCC”) ground water
standards implemented by the COGCC in Table 910-1(as it existed at the time of
the discharge). It should be noted that the highest benzene concentration of
the samples collected at the South Spring tested at 200 times the ground water
standard. Toluene and xylenes were detected at levels below the WQCC standards
reflected in Table 910-1 as it existed at the time of the discharge. But these
levels were above the current WQCC standards for these substances, which had not
yet been incorporated into Table 910-1. Concentrations of these constituents
subsequently decreased due to OXY’s remediation activities. A summary of the
highest results of the analysis of the water sampling is set forth below:

12. On June 19,
2008, OXY replaced existing fencing and installed additional fencing to
facilitate movement of cattle to a new grazing area and to restrict access by
livestock and wildlife to the contaminated water (refer to Attachments 12, 13,
and 14) At COGCC’s request, OXY initiated a tracer study as a method to
estimate the amount of time it would take water to travel from the pit on the
Well pad to the springs along the unnamed tributary. Fluorescein, a fluorescent
dye, was placed in the production pit, however, the dye was not detected at
either trench along the springs by subsequent monitoring.
13. On June 19,
2008, COGCC Staff collected water samples from the North Spring, the S1
Interceptor Trench, and the unnamed tributary in the vicinity of the S1
Interceptor Trench. Analytical results indicated that ground water and surface
water were impacted by hydrocarbon compounds at concentrations exceeding the
Table 910-1 concentration for benzene. It should be noted that the North Spring
tested, at a level more than 300 times the ground water standard for benzene at
this time, a level more than 15 times the ground water standard for toluene, and
a level 1.6 times the ground water standard for xylenes (total) based on the
WQCC standards reflected in Table 910-1 as it existed at the time of the
discharge. At the time of the discharge, Table 910-1 did not reflect the
current WQCC standards for toluene and xylenes (total), and if such standards
are used, the exceedences would be greater. Concentrations of these
constituents subsequently decreased due to OXY’s remediation activities.

14. On June 20,
2008, OXY submitted a Form 19, Spill/Release Report, to the COGCC (COGCC Spill
Tracking No. 1983098).
15. As was
required by Rule 901.e.(4) for the management and remediation of remediation of
certain spills and releases, OXY conducted a sensitive area determination
utilizing the sensitive area decision tree (Figure 901-1) in its response
submitted on July 11, 2008 (see Finding No. 22 below) and determined that the
Well Pad is situated on and around a “sensitive area”. The release or releases
at issue have chemistry that exceeds some criteria found in Box 1. The
production pit on the Well Pad is underlain by a recharge zone for an unconfined
aquifer as is evidenced by the contaminant ground water (Box 2), and has a
hydraulic conductivity that exceeds 10-6 cm/second (Box 3). The area
is not within a known area classified for domestic use by the CDPHE-WQCC or a
local wellhead protection area (Box 4). There are no known domestic water wells
within ⅛-mile or public water supply wells within ¼-mile of the release point
(Box 5); however, there is an improved spring (Conn Camp Spring), the discharge
of which is captured and piped into a cabin within ⅛-mile of the release point.
Although the depth to average high ground water table from the pit bottom is
greater than 20 feet, the release has impacted ground water as is evidenced by
the detections of BTEX and hydrocarbons in the North and South Springs and in
the intermittent tributary (Box 6).
16. On June 20,
2008, COGCC Staff issued OXY Notice of Alleged Violation (“NOAV”) #200191192 for
the Cascade Creek #697-9-60D Well and NOAV #200191194 for the Cascade Creek
#697-09-52B Well and its operations at the Well Pad, which impacted waters at
the North and South Springs. The NOAVs cited violations of the following COGCC
rules:
a.
Rule 209., which requires operators to exercise due care in the protection of
coal seams and water-bearing formations, with special precautions taken in
drilling wells to guard against any loss of artesian water from the stratum in
which it occurs and the contamination of fresh water by objectionable water,
oil, or gas;
b.
Rule 324A.a., which requires operators to take precautions to prevent
significant adverse environmental impacts to air, water, soil, or biological
resources to the extent necessary to protect public health, safety and welfare
and to prevent the unauthorized discharge of oil, gas or E&P waste;
c.
Rule 324A.b., which provides that no operator, in the conduct of any oil or gas
operation shall perform any act or practice which shall constitute a violation
of water quality standards or classifications established by CDPHE-WQCC for
waters of the state;
d.
Rule 902.a., which required at the time of the discharge that a pit used for E&P
shall be constructed and operated to protect waters of the state, and wildlife,
from significant adverse environmental, public health, or welfare impacts from
E&P waste;
e.
Rule 906.a., which provided at the time of the discharge that spills/releases of
E&P waste, including produced fluids, shall be controlled and contained
immediately upon discovery, and that impacts resulting from spills/releases
shall be investigated and cleaned up as soon as practicable;
f.
Rule 906.b.(3), which provided at the time of the discharge that spills/releases
of any size which impact or threaten to impact any waters of the state shall be
verbally reported to the COGCC Director as soon as practicable after discovery;
g.
Rule 907.a.(1), which provided at the time of the discharge that operators shall
ensure that E&P waste is properly stored, handled, transported, treated,
recycled, or disposed to prevent threatened or actual significant adverse
environmental impacts to air, water, soil or biological resources or to the
extent necessary to ensure compliance with allowable concentration levels in
Table 910-1, with consideration to WQCC ground water standards and
classifications; and
h.
Rule 907.a.(2), which requires that E&P waste management activities shall be
conducted, and facilities constructed and operated, to protect the waters of the
state from significant adverse environmental impacts from E&P waste.
The NOAVs
required OXY, by July 7, 2008, to provide written descriptions of: (1) any pits
constructed or used on the Well pad, including size, volume, whether or not the
pit was lined, (2) all fluids (water, drilling, completion, and frac fluids,
flowback, etc.) placed in the pit, including volumes, dates, etc., and provide
haul tickets for all fluids brought from offsite to the pit(s), (3) whether
condensate was observed in the pit(s) during flowback or completion; and (4)
tanks or other containers that were used at this site to manage fluids and any
spills/releases that occurred. Further, OXY was to submit: (1) a Form 27,
Site Investigation and Remediation Workplan, for COGCC review, and (2) all
analytical data collected to date. OXY was also to consult with COGCC and
mitigate impacts to the springs, including, (1) fencing impacted surface water
to restrict access by livestock and wildlife, and (2) providing a supply of
water for drinking and other household use and for watering livestock.
17. COGCC
records reveal that the pit on the Well Pad was never permitted for use as a
production pit (nor was application made by OXY to permit said pit);
consequently, OXY used the pit on the Well Pad to manage produced water from on
or around the date of first completion (October 24, 2007) through the date the
release was discovered (June 16, 2008), a period of 232 days, without an
approved Form 15 pit permit, as COGCC Staff asserts was required by Rule 903.a.
(formerly Rule 903.a.(1)B.).
18. On June 25,
2008, OXY conducted a stakeholder’s meeting which included local ranchers, COGCC
Staff, and OXY Staff, where OXY presented known information regarding the
release, the initial water sampling data, and described initial remedial
action.
19. On June 25,
2008, COGCC Staff inspected the impacted springs, surface water, the Well Pad
and drilling/production pit and pit extension, which had been lined (refer to
Attachment 15).
20. On June 28,
2008, OXY identified another impacted spring to the south of the S1 Interceptor
Trench and installed another interceptor trench adjacent to that spring
(referred to as the S2 Interceptor Trench). The S2 Interceptor Trench was
designed and placed in its location to intercept as much of the contaminated
ground water as possible prior to the contaminated liquids entering the unnamed
tributary to Cascade Canyon.
21. On July 1,
2008, OXY requested, and was granted, an extension to the NOAV abatement
deadline, recited in Finding No. 16, from July 7, 2008 until July 11, 2008 for
submittal of the required information.
22. On July 11, 2008, OXY submitted
a Form 27, Site Investigation and Remediation Workplan (a.k.a., COGCC
Remediation Project No. 4620) to the COGCC. The workplan, in part, provided the
following information:
a. A description of OXY emergency
response operations which were implemented in responding to the discovery of the
release;
b. A description of how OXY
proposed to remediate the impacts of the release;
c. A description of OXY’s plan
to monitor the impacted media (both ground and surface waters);
d. OXY’s proposal to reclaim
impacts caused by construction activities associated with its response to, and
investigation of, the release; and
e. A description of how OXY
managed and disposed of the impacted media (both ground and surface waters) from
the release.
In addition, analytical reports for
samples collected during the emergency response phase of the OXY investigation
and remediation were provided.
23. On July 22, 2008, OXY initiated
a second tracer study as a method to estimate the amount of time it would take
water to travel from the pit on the Well Pad to the springs along the unnamed
tributary (refer to Attachment 16). Rhodamine, a fluorescent dye, was placed in
the production pit, and was first detected at the N Interceptor Trench on July
25, 2008 with peak concentrations measured on July 29, 2008. The results of the
second tracer study indicated that the pit on the Well Pad is hydraulically
connected to the springs along the east side of the unnamed tributary to Cascade
Canyon, and that the travel time is between three to seven days (approximately
91 to 212 feet per day, or 30,000 to 70,000 X 10-6 cm/second) under
those conditions that existed at the time of the study. These results suggest
preferential flow through naturally fractured and weathered bedrock.
Rhodamine was also detected in the
S2 Interceptor Trench on or about October 1, 2008.
24. Between January 2008 and May
2008, OXY estimated in its Site Investigation and Remediation Workplan
that it placed approximately 9,650 barrels of produced water and 195 barrels of
condensate into the unpermitted and unlined production pit on the Well Pad, and
could not provide documentation that it withdrew or removed the produced water
or condensate. Volumetric calculations indicate that the amount of fluids
placed into the pit is about 2-½ times the original capacity of the pit. This
indicates that the fluids were leaking out of the unlined pit and that OXY was
disposing of produced water and associated condensate by percolation from the
pit. The numbers for produced water and condensate were calculated based on
cumulative gas production from the Wells and their associated gas-liquid ratios.
25. OXY has stated that, based on
limited access to the Well Pad during inclement weather, the release or releases
from the unpermitted, unlined pit occurred sometime between January 2008 and May
2008. Therefore, for the purpose of settling this matter under terms agreed to
under this AOC, the parties have agreed to use a violation period of 100 days.
26. Rule 523. specifies a base fine
of One Thousand dollars ($1,000) for each day of violation of Rules 324A.a.,
324A.b., 902.a., 903.a., and 907a.(2). Rule 523.a.(3) specifies that “the
maximum penalty for any single violation shall not exceed Ten Thousand dollars
($10,000) regardless of the number of days of such violation,” unless the
violation results in significant waste of oil and gas resources, damage to
correlative rights, or a significant adverse impact on public health, safety or
welfare or the environment.
27. Based on the
above facts, COGCC Staff contends that the release or releases of fluids from
the produced water pit resulted in a significant adverse impact to the
environment. The release or releases of produced water and condensate impacted
both ground water and surface water with dissolved and free phase hydrocarbon
compounds. In June 2008, at the time of the initial discovery and emergency
response activities, the concentrations of benzene detected in water discharging
from the South Spring and the North Spring were 1,000 µg/l and 1,600 µg/l,
respectively. These benzene concentrations exceeded the ground water standard
of 5 µg/l by 200 times at South Spring and by 300 times at North Spring.
Concentrations of toluene and total xylenes detected in water discharging from
the North Spring also exceeded the ground water standards for these two
compounds. In addition, free phase hydrocarbons and hydrocarbon sheen were
observed on the water discharging from both South Spring and North Spring.
Concentrations of these constituents subsequently decreased due to OXY’s
remediation activities.
A number of other
smaller ground water seeps and springs along an approximately 1,000 foot long
stretch along the eastern bank of the unnamed tributary and the surface water
flowing in the unnamed tributary were also impacted by the release or releases
from the produced water pit.
The South Spring,
North Spring, and the smaller seeps and springs, and surface water were used by
both livestock and wildlife and the area had to be fenced to prevent contact
with and ingestion of the contaminated water. In all, approximately ½-mile of
the unnamed tributary was impacted either by direct discharge of contaminated
ground water or by the construction activities associated with the response and
mitigation measures conducted by OXY.
28. OXY does not admit liability
for any of the alleged Rule violations, and denies that such alleged violations
caused a significant adverse impact to the environment. However, OXY agrees to
pay the following fines as adjusted pursuant to Finding No. 42, and the COGCC
Staff agrees to accept the following fines as adjusted pursuant to Finding No.
42. Both parties agree to do so in order to resolve this matter without the
necessity of a contested hearing.
29. For purposes of settling this
matter, OXY should not be found in violation of Rule 209 because Rule 209 was
not violated here.
30. OXY violated Rule 324A.a.
because it placed produced water and associated condensate in the unlined
production pit on the Well Pad, which failed to contain the fluids which
percolated into the underlying bedrock and impacted groundwater, and by so
doing, OXY failed to take precautions to prevent significant adverse
environmental impacts to air, water, soil, or biological resources to the extent
necessary to protect public health, safety and welfare and to prevent the
unauthorized discharge of oil, gas or E&P waste. A base fine of One Hundred
Thousand dollars ($100,000) has been calculated for the violation of Rule
324A.a.
31. OXY violated Rule 324A.b.
because it placed produced water and associated condensate in the unlined
production pit on the Well Pad, which failed to contain the fluids which
percolated into the underlying bedrock and impacted groundwater, and by so
doing, OXY performed an oil and gas related act or practice which constituted a
violation of the water quality standards or classifications established by
CDPHE-WQCC for waters of the state. A base fine of One Hundred Thousand dollars
($100,000) has been calculated for the violation of Rule 324A.b.
32. OXY violated Rule 902.a. because it placed produced water and
associated condensate in a unlined production pit on the Well Pad, which failed
to contain the fluids which percolated into the underlying bedrock and impacted
groundwater, and by so doing, OXY failed to construct and operate an E&P pit to
protect waters of the state from significant adverse impacts from E&P waste. A
base fine of One Hundred Thousand dollars ($100,000) has been calculated
for the violation of Rule 902.a.
33. OXY violated Rule 903.a.
because it used an unpermitted pit to manage produced water from on or around
the date of well completion (October 24, 2007) through the date the release was
discovered (June 16, 2008). A base fine of One Hundred Thousand dollars ($100,000)
has been calculated for the violation of Rule 903.a.
34. For purposes of settling this
matter, OXY should not be found in violation of Rule 906.a. because OXY
demonstrated a prompt, effective and prudent response to the release.
35. For purposes of settling this matter, OXY should not be found in violation
of Rule 906.b.(3) because OXY demonstrated a prompt, effective and
prudent response to the release.
36. For purposes of settling this
matter, OXY should not be found in violation of Rule 907.a.(1) because
the violation of Rule 907.a.(1) will be combined with the violation of Rule
907.a.(2).
37. OXY violated Rule 907.a.(2) because it placed produced water
and associated condensate in a unlined production pit on the Well Pad, which
failed to contain the fluids which percolated into the underlying bedrock and
impacted groundwater, and by so doing, OXY failed to conduct and operate E&P
waste management activities in a manner which ensured the protection of the
waters of the state from significant adverse environmental impacts from E&P
waste. A base fine of One Hundred Thousand dollars ($100,000) has been
calculated for the violation of Rule 907.a.(2).
38. COGCC Staff specifically
reserve the right to proceed as to alleged violations of Rules 906.a.,
906.b.(3), and 907.a.(1), if this matter is not resolved by this AOC. Nothing
within this AOC should be construed as the COGCC Staff waiving their right to
prosecute any violation set forth in this AOC in the event that this AOC is not
executed by the parties and approved by the Commission.
39. In summary,
OXY should be found in violation of Rules 324A.a., 324A.b., 902.a., 903.a., and
907a.(2) as described herein, for failing to properly permit, construct,
maintain, and repair the pit on the Well pad so that E&P waste was not released,
and base fines levied as compiled in the table below:

40. Because the base fine for these
violations is set at $1000 per day of violation, the aggravating factors set
forth in Rule 523.d. are not applicable by their terms.
41. Pursuant to Rule 523.d, the
following mitigating factors were applied to reduce the total base fine amount
by twenty two percent (22%):
(1)
Twelve percent (12%)
under Rule 523.d.(2), because OXY demonstrated a prompt, effective and prudent
response to the violations, and Rule 523.d.(3), because OXY cooperated with the
Commission. OXY’s response to the release was comprehensive and effective in
limiting the impact of the release, including reducing the concentrations of
constituents towards meeting applicable WQCC ground water standards. Within two
hours of the report of the release, OXY mobilized equipment, constructed two
dams, and sampled the impacted area and the downstream drainages to ensure that
the contamination did not reach the down-gradient creek. OXY promptly
constructed berms, trenches, and bypasses, as well as the placement of booms, to
further confine the release. OXY constantly monitored and sampled numerous
points in and around the release areas, and hauled and disposed of contaminated
fluids. Further, OXY voluntarily performed an ORC-Advance chemical oxidation
treatment to aid in the breakdown of the released hydrocarbons; and
(2)
Ten percent (10%)
under Rule 523.d.(6), because OXY incurred approximately $1,500,000 in costs for
its remediation efforts to date, and these costs substantially exceed any
economic benefit from the violations. Further, OXY has spent another $8,000,000
to decrease the risk of future ground or surface water impacts from its
operations in this area by reducing the number of the pits it uses to manage
fluids in the area from approximately 23 to one fresh water pond and ten treated
produced water ponds and is now utilizing onsite produced water storage tanks
with automatic well shut-in technology should the storage tanks reach capacity.
42. The parties agree to a fine of
Three Hundred Ninety Thousand dollars ($390,000), which takes into consideration
a 22% fine reduction for mitigating factors.
43.
Payment of the
fine pursuant to this AOC does not relieve the operator from its obligations to
complete abatement or corrective actions set forth in the NOAV, as may be
amended or modified by Staff.
44. OXY should
execute this AOC no later than 14 days after the date it is executed by Staff
for recommendation to the Commission for expedited approval. Fines may increase
if this matter is not recommended for expedited approval.
45. OXY, or its
successors or assigns, should be required to remain responsible for complying
with this AOC, notwithstanding any subsequent sale of property.
46.
Pursuant to Article IX, of the “Memorandum
of Agreement” between the Water Quality Control Division (“WQCD”) and the COGCC,
adopted February 15, 2000, COGCC Staff conferred with WQCD enforcement staff in
determining the monetary penalty against OXY for violations of WQCC standards
for surface waters. WQCD indicated it agrees with the fine and the terms of
this AOC and will not pursue any additional penalty.
47. OXY agrees to the findings of this AOC only for the purpose of
expeditiously resolving the matter without a contested hearing. Notwithstanding
the above, OXY does not admit to any of the factual or legal determinations made
by the Commission herein, and fully reserves its right to contest same in any
future action or proceeding other than a proceeding to enforce this AOC.
