Final NPDES General Permit for Oil and Gas Exploration, 
Development and Production Facilities in Cook Inlet, AL (AKG285000)

AGENCY: Environmental Protection Agency (EPA), Region 10.

ACTION: Notice of final NPDES general permit.

-----------------------------------------------------------------------

SUMMARY: The Director, Office of Water, EPA Region 10, is issuing the 
National Pollutant Discharge Elimination System (NPDES) General Permit 
for Cook Inlet, Alaska, pursuant to the provisions of the Clean Water 
Act, 33 U.S.C. 1251 et seq. The permit authorizes discharges from 
existing oil and gas exploration, development and production platforms 
and shore-based facilities in Upper Cook Inlet (north of the 
Forelands). The permit also authorizes future exploratory operations in 
Cook Inlet north of the line between Cape Douglas on the west, and Port 
Chatham on the east. All dischargers covered by this permit fall within 
the Coastal and Offshore Subcategory of the Oil and Gas Extraction 
Point Source Category (40 CFR part 435, subparts A and D).
    Discharges authorized by this permit include drilling muds and 
cuttings; produced water; deck drainage; sanitary and domestic wastes; 
completion, workover, well treatment and test fluids; and miscellaneous 
discharges. Discharges from facilities in the Onshore Subcategory (40 
CFR Part 435, Subpart C), or to wetlands adjacent to the territorial 
seas and inland coastal waters of Alaska are not authorized by this 
permit. The permit does not authorize discharges from ``new sources,'' 
as defined in 40 CFR 122.2.
    The existing permit was published in the Federal Register at 51 FR 
35460 on October 3, 1986, and authorized discharges from oil and gas 
facilities in Upper Cook Inlet, and from oil and gas exploration wells 
in federal waters offered for lease by the U.S. Department of the 
Interior's Minerals Management Service (MMS) in Federal Lease Sales 55 
(Gulf of Alaska) and 60 (Cook Inlet) in state waters offered for lease 
by the State of Alaska in Lease Sales 32, 33, 35, 40, 46A, and 49. The 
permit issued in 1986 also covered areas offered under state lease 
sales held during the effective period of the permit. The area of 
coverage for the permit issued today is not linked to lease sale areas, 
and covers all state and federal waters in Cook Inlet north of the line 
between Cape Douglas on the west and Port Chatham on the east.
    A total of 23 facilities were covered under the 1986 general 
permit. Of those 23 facilities, 18 are currently active. All of those 
permittees have complied with the reissuance application procedures and 
indicated preference to be covered under this general permit.

FOR FURTHER INFORMATION CONTACT: Ms. Laurie Mann, EPA Region 10, 1200 
Sixth Avenue, Seattle, Washington 98101, Telephone: (206) 553-1583, or

SUPPLEMENTARY INFORMATION:

Public Comment

    Pursuant to section 402 of the Clean Water Act (CWA), 33 U.S.C. 
1342, EPA proposed and solicited comments on NPDES general permit 
AKG285000 at 60 FR 48796 (September 20, 1995). The public comment 
period was scheduled to close November 30, 1995, but was extended to 
January 29, 1996 at 60 FR 6155 (November 30, 1995). Public hearings 
were held in Anchorage on November 28, 1995, Soldotna on November 29, 
1995, and Homer on January 25, 1996.
    EPA Region 10 received over 350 letters, petitions and verbal 
comments from tribal, federal and state governments, companies, non-
profit organizations, and individuals. All comments specifically 
addressing the draft Cook Inlet permit which were submitted during the 
public comment period were considered during finalization of the 
permit. Changes have been made from draft permit to the final permit in 
response to public and governmental comment. All comments, along with 
the EPA's responses, are summarized in the Response to Comments, which 
may be obtained from Laurie Mann at the above address, or may be 
obtained from the EPA Region 10 web site at www.epa.gov/r10earth/
offices/water/ow.htm.

Other Legal Requirements

Ocean Discharge Criteria Evaluation

    EPA Region 10 has determined that discharges occurring under the 
proposed permit are in compliance with section 403 of the Clean Water 
Act. These discharges will not cause unreasonable degradation as long 
as the depth-related conditions, discharge restrictions, and 
environmental monitoring requirements in the permit are met. For 
example, all discharges are prohibited within the boundaries, or within 
1,000 meters of a coastal marsh, river delta, river mouth, and 
designated Critical Habitat Areas, Areas of Special Attention, National 
Park, State Game Refuges, and State Game Sanctuaries. The permit also 
prohibits discharges in Kamishak Bay, Chinitna Bay, and Tuxedni Bay.

Coastal Zone Management Act

    The State of Alaska, Office of Management and Budget, Division of 
Governmental Coordination found this action to be consistent with the 
approved Alaska Coastal Zone Management Program.

Endangered Species Act

    EPA has determined that issuance of the Cook Inlet General Permit 
will not

[[Page 11886]]

adversely affect any listed, threatened, or endangered species or 
designated habitat, and National Marine Fisheries Service (NMFS) and 
U.S. Fish and Wildlife provided written concurrence with EPA's 
determination on the proposed NPDES General Permit.

State Water Quality Standards and State Certification

    The State of Alaska, Department of Environmental Conservation, has 
issued a Certificate of Reasonable Assurance that the subject 
discharges comply with the Alaska State Water Quality Standards. The 
EPA has considered Alaska's antidegradation policy (18 Alaska 
Administrative Code (AAC 70.101(c)). The reissuance of this permit will 
not result in additional pollutant loading to the receiving water; 
therefore this action complies with the State's antidegradation policy.

Executive Order 12866

    EPA has determined that this general permit is not a ``significant 
regulatory action'' under the terms of Executive Order 12866 and is 
therefore not subject to OMB review.

Paperwork Reduction Act

    The information collection requirements of this permit were 
previously approved by the Office of Management and Budget (OMB) under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., 
and assigned OMB control numbers 2040-0086 (NPDES permit application) 
and 2040-0004 (discharge monitoring reports).

Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA), 5 U.S.C. 601 et seq., 
requires that EPA prepare a regulatory flexibility analysis for rules 
subject to the requirements of 5 U.S.C. 553(b) that have a significant 
impact on a substantial number of small entities. The permit issued 
today, however, is not a ``rule'' subject to the requirements of 5 
U.S.C. 553(b) and is therefore not subject to the Regulatory 
Flexibility Act.

Unfunded Mandates Reform Act

    Section 201 of the Unfunded Mandates Reform Act (UMRA), Public Law 
104-4, generally requires Federal agencies to assess the effects of 
their ``regulatory actions'' (defined to be the same as ``rules'' 
subject to the RFA) on tribal, state, and local governments and the 
private sector. The permit issued today, however, is not a ``rule'' 
subject to the RFA and is therefore not subject to the requirements of 
UMRA.

Appeal of Permit

    Any interested person may appeal the Cook Inlet General NPDES in 
the Federal Court of Appeals in accordance with Section 509(b)(1) of 
the Clean Water Act. This appeal must be filed within 120 days of 
permit issuance. The date of permit issuance is defined at 40 CFR 23.2 
to be at 1:00 PM eastern time, two weeks after the date of publication 
in the Federal Register.

Authorization To Discharge Under the National Pollutant Discharge 
Elimination System for Oil and Gas Exploration, Development and 
Production

    In compliance with the provisions of the Clean Water Act, 33 U.S.C. 
1251 et seq., the ``Act'', the following discharges are authorized in 
accordance with this National Pollutant Discharge Elimination System 
(``NPDES'').

authorization to discharge prior to commencement of discharges under 
this permit.

D. All Facilities Covered by the Permit

1. Duty To Reapply and/or Notice of Intent To Continue Activity
    If the Permittee wishes to discharge under the authority of this 
permit after its expiration date, the Permittee must submit a notice of 
intent to EPA to do so. The Notice of Intent must be submitted at least 
180 days before the expiration date of this permit. An NPDES permit 
application (EPA Form 3510-2C, Wastewater Discharge Information, 
Consolidated Permits Program (revised February 1985)) constitutes a 
complete Notice of Intent. Timely receipt by EPA of a complete Notice 
of Intent will qualify the Permittee for an administrative extension of 
its authorization to discharge under this permit pursuant to 5 USC 
Section 558(c).
2. Termination of Discharges
    The Permittee must notify EPA within 30 days following cessation of 
discharges from the discharge site. The notification may be provided in 
a Discharge Monitoring Report (DMR) or under separate cover.
3. Submission of Requests To Be Covered and Other Reports
    Reports and notifications required herein must be submitted to the 
following addresses.
    All requests for coverage: Director, Water Division, US EPA, Region 
10, Attn: NPDES Permits Unit, OW-130, 1200 6th Avenue, Seattle, 
Washington 98101, Phone: (206) 553-1583.
    All monitoring reports and notifications of non-compliance: 
Director, Water Division, US EPA, Region 10, NPDES Compliance Unit, OW-
133, 1200 6th Avenue, Seattle, Washington 98101, Phone: (206) 553-1846.
    For discharges to state waters only: Alaska Department of 
Environmental Conservation, Attn: Watershed Management Section, 555 
Cordova Street, Anchorage, AK 99501.

E. Changes From Coverage Under General Permit To Coverage Under 
Individual Permit

    1. The Director may require any permittee discharging under the 
authority of this permit to apply for and obtain an individual NPDES 
permit when any one of the following conditions exist:
    a. The discharge(s), including stormwater, is a significant 
contributor of pollution.
    b. The Permittee is not in compliance with the conditions of this 
general permit.
    c. A change has occurred in the availability of the demonstrated 
technology or practices for the control or abatement of pollutants 
applicable to the point source.
    d. Effluent limitation guidelines are promulgated for point sources 
covered by this permit.
    e. The point sources covered by this permit no longer:
    (1) Involve the same or substantially similar types of operations,
    (2) Discharge the same types of wastewaters,
    (3) Require the same effluent limitations or operating conditions, 
or
    (4) Require the same or similar monitoring.
    f. In the opinion of the Director, the discharges are more 
appropriately controlled under an individual permit than under a 
general NPDES permit.
    2. The Director may require any permittee authorized by this permit 
to apply for an individual NPDES permit only if the Permittee has been 
notified in writing that an individual permit application is required.
    3. Any permittee authorized by this permit may request to be 
excluded from the coverage of this general permit by applying for an 
individual permit. The owner or operator must submit an application 
together with the reasons supporting the request to the Director no 
later than 90 days after the effective date of the permit.
    4. When an individual NPDES permit is issued to a permittee 
otherwise subject to this general permit, the applicability of this 
general permit to that owner or operator is automatically terminated on 
the effective date of the individual permit.

II. Prohibited Areas of Discharge and Depth-Related Requirements

Harbor on Chisik Island (latitude 60 deg.06'36'' North, longitude 
152 deg.32'54'' West).

III. Effluent Limitations and Monitoring Requirements

    The operators must limit discharges as specified in the permit 
below. All figures represent maximum effluent limits unless otherwise 
indicated. The Permittee must comply with the following effluent limits 
at all times unless provided for by this permit (e.g., unanticipated 
bypass) regardless of the frequency of monitoring or reporting required 
by other provisions of this permit.

A. Representative Sampling (Routine and Non-Routine Discharges)

    1. The operators must collect all effluent samples from the 
effluent stream prior to discharge into the receiving waters. Samples 
and measurements must be representative of the volume and nature of the 
monitored discharge.
    2. In order to ensure that the effluent limits set forth in this 
permit are not violated at times other than when routine samples are 
taken, the operators must collect additional samples at the appropriate 
outfall(s), and analyze them for the parameters appropriate to that 
waste stream, limited in Parts III.B.-III.I. of this permit, whenever 
any discharge occurs that may reasonably be expected to cause or 
contribute to a violation that is unlikely to be detected by a routine 
sample.
    3. The Permittee must collect such additional samples as soon as 
possible after the spill or discharge. The samples must be analyzed in 
accordance with the monitoring requirements in Parts III.B.-III.I. of 
this permit. In the event of an anticipated bypass, as defined in Part 
V.G. of this permit, the Permittee must collect and analyze additional 
samples as soon as the bypassed effluent reaches the outfall. The 
Permittee must report all additional monitoring in accordance with Part 
IV.D.

B. Drilling Mud, Drill Cuttings (Discharge 001)

1. Effluent Limitations
    In addition to the restrictions set out in Parts III.A., III.B.2-3. 
and IV, the Permittee must comply with the following effluent 
limitations and monitoring requirements.

1 Maximum flow rate of total muds and cuttings includes predilutant water; water depths are measured from mean
  lower low water.
2 Report total volumes for all types of operations (exploratory, production and development). For exploratory
  operations, drilling discharges are limited to no more than five wells at a single drilling site. If a step-
  out or sidetracked well is drilled from a previously drilled hole, the step-out well is counted as new well.
  Dual lateral, which involve drilling a primary well bore and kicking off a second leg, are considered to be
  one well. Requests to discharge from more than five wells per site will be considered by the Water Division
  Director on a case-by-case basis.

    a. Mineral oil pills. The discharge of residual amounts of mineral 
oil pills (mineral oil plus additives) is authorized by the permit 
provided that the mineral oil pill and at least a 50 bbl buffer of 
drilling fluid on either side of the pill are removed from the 
circulating drilling fluid system and not discharged to waters of the 
United States. If more than one pill is applied to a single well, the 
previous pill and buffer must be removed prior to application of a 
subsequent pill.
    (2) Residual mineral oil concentration in the discharged mud must 
not exceed 2% volume/volume (API Recommended Practice 13-1, 1990) (see 
Part III.B.2.c.). If drilling mud containing residual mineral oil pill 
(after pill and buffer removal) is discharged, the following 
information must be reported within 60 days of the discharge:
    (a) Dates of pill application, recovery, and discharge;
    (b) Results of the Drilling Fluids Toxicity Test on samples of the 
mud before each pill is added and after removal of each pill and buffer 
(taken when residual mineral oil pill concentration is expected to 
greatest);
    (c) Name of spotting compound and mineral oil product used;
    (d) Volumes of spotting compound, mineral oil, water, and barite in 
the pill;
    (e) Total volume of mud circulating prior to pill application, 
volume of pill formulated, and volume of pill circulated;
    (f) Volume of pill recovered, volume of mud buffer recovered, and 
volume of mud circulating after pill and buffer recovery;
    (g) Percent recovery of the pill (include calculations);
    (h) Estimated concentrations of residual spotting compound and 
mineral oil in the sample of mud discharged, as determined from amounts 
added and total mud volume circulating prior to pill application;
    (i) Measured oil content of the mud samples, as determined by the 
API retort method; and
    (j) An itemization of other drilling fluid components and specialty 
additives contained in the discharged mud with concentrations reported 
in gal/bbl or lb/bbl.
2. Monitoring and Reporting Requirements
    Monitoring must be conducted according to test procedures approved 
under 40 CFR Part 136, unless other test procedures are specified here 
or elsewhere in this permit. Representative sampling requirements are 
discussed in Part III.A.
    a. Chemical Inventory. For each mud system discharged, the 
Permittee must maintain a precise chemical inventory of all 
constituents added downhole, including all drilling mud additives used 
to meet specific drilling requirements. The Permittee must maintain 
these records for each mud system for a period of five years, and must 
make these records available to the EPA upon request.
    b. End of well reports. End of well reports contain the information 
required in parts c-f below, and must be submitted within 90 days of 
well completion.
    c. Diesel oil. 1. Compliance with the limitation on diesel oil must 
be demonstrated by gas chromatography (GC) analysis of drilling mud 
collected from the mud used at the greatest well depth (``end-of-well'' 
sample) and of any muds or cuttings which fail the daily Static Sheen 
Test (Part III.B.2.d. below). In all cases, the determination of the 
presence or absence of diesel oil must be based on a comparison of the 
GC spectra of the sample and of diesel oil in storage at the facility. 
The method for GC analysis must be that described in ``Analysis of 
Diesel Oil in Drilling Fluids and Drill Cuttings'' (CENTEC, 1985) 
available from EPA, Region 10. Gas chromatography/mass spectrometry 
(GC/MS) may be used if an instance should arise where the operator and 
EPA determine that greater resolution of the drilling mud 
``fingerprint'' is needed for a particular drilling mud sample.
    2. Reporting. The results and raw data, including the spectra, from 
the GC analysis must be provided to the Director by written report (1) 
within 30 days of a positive result with the Static Sheen Test when a 
discharge has occurred, or (2) for the end-of-well analysis, within 90 
days of well completion.
    d. Static Sheen Test. 1. The Permittee must perform the Static 
Sheen Test on separate samples of drilling muds and cuttings, as 
required in Appendix 1 to Subpart A of 40 CFR Part 435. Samples must be 
collected on each day of discharge and prior to bulk discharges.
    2. The test must be conducted in accordance with ``Approved 
Methodology: Laboratory Sheen Tests for the Offshore Subcategory, Oil 
and Gas Extraction Industry'' which is Appendix 1 to Subpart A of 40 
CFR Part 435. For discharge below ice or during periods of unstable or 
broken ice, water temperature for the Static Sheen Test must 
approximate surface water temperatures at ice breakup.
    3. Whenever muds or cuttings fail the Static Sheen Test and a 
discharge has occurred in the past 24 hours, the Permittee is required 
to analyze an undiluted sample of the material which failed the test to 
determine the presence or absence of diesel oil. The determination and 
reporting of results must be performed according to Part III.B.2.c. 
above.
    e. Toxicity test for drilling fluids. 1. If no mineral oil is used 
(Part III.B.1.a.), a toxicity test must be conducted monthly to 
determine compliance with the drilling fluid toxicity limit. At the 
end-of-well, a sample must be collected for toxicity testing. This 
sample can also serve as the monthly monitoring sample.
    2. The Permittee must complete a minimum of two toxicity tests on 
each mud system where a mineral oil lubricity or spotting agent is 
used. One sample must be collected before applying the pill and one 
after removing the pill (see Part III.B.1.a.(2)). The ``after pill'' 
sample test results can be used as the monthly monitoring sample. If 
the well is completed within 96 hours of collection of the ``after 
pill'' drilling mud sample, then these test results can also serve as 
the end-of-well test.
    3. The testing and reporting of drilling fluid toxicity test 
results must be in accordance with Appendix 2 to Subpart A of 40 CFR 
Part 435 (Drilling Fluids

[[Page 11891]]

Toxicity Test) using either the full or partial toxicity test. If the 
partial toxicity test shows a failure, however, all testing of future 
samples from that well shall be conducted using the full toxicity test 
method to determine the 96-hour LC50. Results of drilling fluid 
toxicity tests (in terms of pass/fail or 96-hr LC50 value) must be 
reported on the DMRs, and complete copies of the test reports must be 
attached to the DMR.
    f. Metals analysis. 1. The Permittee shall analyze each discharged 
mud system for the following metals: barium, cadmium, chromium, copper, 
mercury, zinc, and lead. Analyses for total recoverable concentrations 
shall be conducted and reported for each metal utilizing the methods 
specified in 40 CFR Part 136. The results shall be reported in ``mg/kg 
of whole mud (dry weight)'' and the moisture content (percent by 
weight) of the original drilling mud sample shall be reported.
    2. Samples shall be collected when the residual mineral oil 
concentration is at its maximum value (see Part III.B.1.a.). If no 
mineral oil is used, the analysis shall be done on a drilling mud 
sample collected from the mud system used at the greatest well depth. 
All samples shall be collected prior to any predilution. Each drilling 
mud sample shall be of sufficient size to allow for both the chemical 
testing described here and toxicity testing described above in Part 
III.B.2.e.
    g. Mercury and cadmium content of barite. 1. The Permittee must 
analyze a representative sample of stock barite once prior to drilling 
each well and submit the results for total mercury and total cadmium in 
the DMR upon well completion. Analyses must be conducted by absorption 
spectrophotometry and results expressed as mg/kg (dry weight) of 
barite.
    2. If more than one well is drilled at a site, new analyses are not 
required for subsequent wells if no new supplies of barite have been 
received since the previous analysis. In this case, the DMR should 
state that no new barite was received since the last reported analysis. 
Operators may provide certification, as documented by the supplier(s), 
that the barite meets the above limits. The concentration of mercury 
and cadmium in stock barite must be reported on the DMR as documented 
by the supplier.
3. Environmental Monitoring Requirements
    a. Within 4000 m of sensitive areas. Monitoring of the fate and 
effects of drilling muds and/or cuttings discharges are required for 
new exploration facilities when the location of the discharges is 
within 4000 m of an area such as a coastal marsh, river delta, river 
mouth, designated AMSA, game refuge, game sanctuary, critical habitat 
area, or National Park. Discharges are prohibited within 1000 m of 
sensitive areas (see Part II.C.2.).
    b. Environmental Monitoring Study. If monitoring is required by 
Part III.B.3.a., the Permittee must submit a plan of study for 
environmental monitoring to EPA for review with, or prior to, 
submission of a written request for authorization to discharge (Parts 
I.A. and I.B.).
    c. Objectives. The objectives of the environmental monitoring must 
be to:
    (1) Monitor for discharge-related impacts,
    (2) Determine statistically significant changes in sediment 
pollutant concentrations and sediment toxicity with time and distance 
from the discharge,
    (3) Monitor for discharge related impacts to the benthic community,
    (4) Assess whether any impacts warrant an adjustment of the 
monitoring program, and
    (5) Provide information for permit reissuance.
    d. Requirements. The monitoring must include, but not be limited 
to, relevant hydrographic, sediment hydrocarbon, and heavy metal data 
from surveys conducted before and during drilling mud disposal and up 
to at least one year after drilling operations cease. The monitoring 
plan must address:
    (1) The monitoring objectives,
    (2) Appropriate null and alternate test hypotheses,
    (3) A statistically valid sampling design,
    (4) All monitoring procedures and methods,
    (5) A quality assurance/quality control program,
    (6) A detailed discussion of how data will be used to meet, test 
and evaluate the monitoring objectives, and
    (7) A summary of the results of previous environmental monitoring 
as they apply to the proposed program plan.
    e. Reporting requirements. (1) The Permittee must analyze the data 
and submit a draft report within 180 days following the completion of 
sample collection. The report must address the environmental monitoring 
objectives by using appropriate descriptive and analytical methods to 
test for and to describe any impacts of the effluent on sediment 
pollutant concentrations, sediment quality, water quality and/or the 
benthic community. The report must include all relevant quality 
assurance/quality control (QA/QC) information, including but not 
limited to instrumentation, laboratory procedures, detection limits/
precision requirements of the applied analyses, and sample collection 
methodology.
    (2) The EPA will review the draft report in accordance with the 
environmental monitoring objectives and evaluate it for compliance with 
the requirements of the permit. If revisions to the report are 
required, the Permittee must complete them and submit the final report 
to EPA within two months of the Director's request. The Permittee will 
be required to correct, repeat and/or expand environmental monitoring 
programs which have not fulfilled the requirements of the permit.
    f. Modification of Monitoring Program. The monitoring program may 
be modified if EPA determines that it is appropriate. The modified 
program may include changes in sampling stations, sampling times, and/
or parameters.
    g. Exemption. Region 10 may grant a written exemption to this 
requirement if the Permittee can satisfactorily demonstrate that 
information on the fate and effects of the discharge is available and/
or the discharge will not have significant impacts on the area of 
biological significance. An exemption to post-drilling monitoring will 
be granted if no impact was indicated during drilling. An exemption 
request must be submitted to the EPA for review with, or prior to, 
submission of a written request for authorization to discharge (Parts 
I.A. and I.B.).

C. Deck Drainage (Discharge 002)

1. Effluent Limitations
    In addition to the restrictions set out in Parts III.A., III.C.2-5. 
and IV, the Permittee must comply with the following effluent 
limitations and monitoring requirements.

                                                   permit. \3\
----------------------------------------------------------------------------------------------------------------
\1\ If discharge occurs during broken or unstable ice conditions, or during stable ice conditions, the Static
  Sheen Test must be used (see Appendix 1 to 40 CFR part 435, subpart A).
\2\ Contaminated deck drainage must be processed through an oil-water separator prior to discharge and samples
  for that portion of the deck drainage collected from the separator effluent must be sampled for WET testing.
\3\ Sample must be collected during a significant rainfall or snowmelt. If discharge of deck drainage separate
  from produced water is initiated after the first year of the permit, sampling must occur during the year
  following the initiation of separate deck drainage discharge.
\4\ With the final report for each test, the following must also be reported: date and time of sample, the type
  of sample (i.e., rainfall or snowmelt), estimate of daily flow and basis for the estimate (e.g., turbine
  meters, monthly precipitation, estimated washdown).

2. Drains
    Area drains for either washdown or rainfall that may be 
contaminated with oil and grease must be separated from those area 
drains that would not be contaminated. The contaminated deck drainage 
must be processed through an oil-water separator prior to discharge and 
samples for that portion of the deck drainage collected from the 
separator effluent must be tested for sheen.
3. Commingled Wastestreams
    If deck drainage is commingled with produced water, then this 
discharge must be considered produced water for monitoring purposes 
(Part III.F.). The estimated deck drainage flow rate must be reported 
in the comment section of the DMR.
4. Unstaffed Facilities
    Monitoring of unstaffed facilities is not required. Written 
notification that a facility is no longer staffed must be provided to 
EPA prior to terminating monitoring requirements.
5. Monitoring Requirements
    Monitoring must be conducted according to test procedures approved 
under 40 CFR 136, unless other test procedures are specified here or 
elsewhere in this permit. Representative sampling requirements are 
discussed in Part III.A.

D. Sanitary Wastes and Domestic Wastes (Discharges 003, 004)

----------------------------------------------------------------------------------------------------------------
\1\ Permittee must monitor by observing the surface of the receiving water in the vicinity of the outfall(s)
  during daylight at the time of maximum estimated discharge. For domestic waste, observations must follow
  either the morning or midday meal.
\2\ In cases where sanitary and domestic wastes are mixed prior to discharge, and sampling of the sanitary waste
  component stream is infeasible, the discharge may be sampled after mixing. In such cases, the discharge
  limitations for sanitary wastes must apply to the mixed waste stream.
\3\ The numeric limits for BOD and TSS apply only to discharges to state waters.
\4\ The TSS limitation for biological treatment units is a net value. The net TSS value is determined by
  subtracting the TSS value of the intake water from the TSS value of the effluent. Report the TSS value of the
  intake water on the comment section of the DMR. For those facilities that use filtered water in the biological
  treatment units, the TSS of the effluent may be reported as the net value.
Samples collected to determine the TSS value of the intake water must be taken on the same day, during the same
  time period that the effluent sample is taken. Intake water samples must be taken at the point where the water
  enters the facility prior to mixing with other flows. Influent samples must be taken with the same frequency
  that effluent samples are taken.

2. Discharge Below Water Surface
    Domestic and sanitary wastes must be discharged below the water 
surface.
3. Monitoring Requirements
    Monitoring must be conducted according to test procedures approved 
under 40 CFR 136, unless other test procedures are specified here or 
elsewhere in this permit. Representative sampling requirements are 
discussed in Part II.B.
    Fecal Coliform Monitoring. Permittees must submit a facility 
specific mixing zone application to ADEC based on the first 12 months 
monitoring data within 18 months after the effective date of the permit 
(or within 18 months after commencement of discharge for new 
dischargers).

E. Miscellaneous Discharges (Discharges 005-014)

1. Effluent Limitations
    In addition to the restrictions set out in Parts III.A., III.E.2-4, 
and IV, the discharge of desalination unit wastes (005); blowout 
preventer fluid (006); boiler blowdown (007): fire control system test 
water (008); non-contact cooling water (009); uncontaminated ballast 
water (010); bilge water (011); excess cement slurry (012); mud, 
cuttings, cement at the seafloor (013); and waterflooding (014) must 
comply with the following effluent limitations and monitoring 
requirements.

----------------------------------------------------------------------------------------------------------------
\1\ For Uncontaminated Ballast Water (010) and Bilge Water (011) only: uncontaminated ballast and bilge water
  must be processed through an oil-water separator prior to discharge. If discharge of bilge water occurs during
  broken, unstable, or stable ice conditions, the sample type/method used to determine compliance with the no
  free oil limitation must be ``Grab Static Sheen Test'' (Appendix 1 to Subpart A of 40 CFR Part 435). For
  discharges above stable ice, below ice, to unstable or broken ice, a water temperature that approximates
  surface water temperatures after breakup must be used.

2. Chemical Inventory
     The Permittee must maintain an inventory of the type and quantity 
of chemicals (other than fresh or seawater) added to waterflooding, 
non-contact cooling water and desalination systems. The inventory(ies) 
must be submitted annually. The annual inventories must be assembled 
for the calendar year, and must be submitted to the EPA within 90 days 
of the completion of the calendar year.
3. Commingled Wastestreams
     If excess waterflood water is added to the produced water 
discharge in order to minimize the possibility of line freezing, then 
this discharge must be considered produced water for monitoring 
purposes. The estimated waterflood flow rate must be reported in the 
comment section of the DMR.
4. Monitoring Requirement
    Monitoring must be conducted according to test procedures approved 
under 40 CFR 136, unless other test procedures are specified here or 
elsewhere in this permit. Representative sampling requirements are 
discussed in Part III.A.

F. Produced Water (Discharge 015)

\1\ Fifteen months after permit issuance, a report summarizing the concentrations of the individual TAH
  components (benzene, toluene, ethylbenzene and xylene isomers) and individual TAqH components from data
  collected during the first year of permit coverage must be provided to the EPA.

2. Rerouting Platform Discharge to a Shore-Based Facility
    In situations where the platforms are not able to treat produced 
water and a bypass may occur, the Baker and Dillon platforms may route 
their produced water discharge to the Granite Point Production Facility 
for treatment and discharge; the Anna and Bruce platforms may route 
their produced water discharge to the East Foreland Production Facility 
for treatment and discharge. The Permittee must report rerouting by 
telephone or facsimile within 24 hours of rerouting, and must provide a 
written submission within five days of rerouting that describes why 
rerouting was necessary, and the anticipated time that rerouting is 
expected to continue. The permittee must cease rerouting as soon as 
possible.
3. Interim Produced Water Limitations
    Facilities which obtain authorization to discharge produced water 
subject to interim produced water limitations (see Part I.B.) must 
submit a facility specific mixing zone application to ADEC based on the 
first 12 months of monitoring data within 18 months after commencement 
of discharge.
4. Trading Bay Groundwater
    Trading Bay is authorized to discharge treated groundwater 
extracted pursuant to State Compliance Order #91-23-01-053-02 as part 
of the produced water waste stream.
5. Spill Clean-Up
    Water that is collected as a result of spill clean-up can be 
treated as produced water and discharged with the produced water waste 
stream. The Permittee must report the treatment and discharge of spill 
clean-up water to the EPA within 24 hours of initiating such treatment, 
and must provide a written submission within five days of initiating 
treatment that describes the spill, the anticipated volume of spill 
clean-up water, and the anticipated time that treatment and discharge 
of spill clean-up water is expected to continue.
6. Phillips A/Tyonek
    Two sets of limits for Phillips A/Tyonek are listed at Part 
III.F.1. The ``gas'' limits are effective at the time of permit 
issuance, and will continue to be the effective permit limits until 
Phillips A/Tyonek initiates discharge of crude related discharge 
directly from the Phillips A/Tyonek platform. The Permittee must submit 
a notification letter to EPA prior to initiating the discharge of crude 
related produced water from the platform. The ``crude'' limits become 
effective on the day identified in the notification letter. A facility 
specific mixing zone application must be submitted to ADEC for Phillips 
A/Tyonek based on the first 12 months monitoring data within 18 months 
after commencement of crude related produced water discharges.
7. Monitoring Requirements
     Monitoring must be conducted according to test procedures approved 
under 40 CFR 136, unless other test procedures are specified here or 
elsewhere in this permit. Representative sampling requirements are 
discussed in Part III.A.
    a. Total Aromatic Hydrocarbons (TAH) and Total Aqueous Hydrocarbons 
(TAqH). For analysis of TAH and TAqH, all analytical requirements cited 
in the Alaska Standards, 18 AAC 70.020(b) are applicable.
    b. Whole effluent toxicity. (1) The Permittee must conduct tests on 
grab effluent samples with one vertebrate and two invertebrate species, 
as follows.
    Vertebrate (survival and growth): Inland silverside, Menidia 
beryllina.
    Invertebrate: Atlantic myside Mysidopsis bahia (survival, growth 
and fecundity test) and one of the following two bivalve species tests: 
Mussel Mytilis sp. or Pacific oyster Crassostrea gigas (larval 
development test ). Due to seasonal variability, testing may be 
performed during reliable spawning periods (e.g. December through 
February for mussels; June through August for oysters).
    (2) Each year, the permittee must re-screen with the three species 
listed above, and continue to monitor with the most sensitive species. 
Rescreening must consist of one test conducted at a different time of 
year from the previous years test.
    (3) The presence of chronic toxicity must be estimated as specified 
in ``USEPA Short-Term Methods for Estimating the Chronic Toxicity of 
Effluents and Receiving Waters to Marine and Estuarine Organisms, 
Second Edition,'' (EPA/600/4-91/003). For the bivalve species, chronic 
toxicity must be estimated as specified in ``Short-Term Methods for 
Estimating the Chronic Toxicity of Effluents and Receiving Water to 
West Coast Marine and Estuarine Organisms'' (EPA/600/R-95/136).
    (4) Results must be reported in TUc, where 
TUc = 100/NOEC. The reported NOEC must be the highest NOEC 
calculated for the applicable survival, growth or fecundity endpoints.
    (5) A series of five dilutions and a control will be tested. The 
series must include the instream waste concentration (IWC), two 
dilutions above the IWC, and two dilutions below the IWC. The IWC is 
the concentration of effluent at the edge of the mixing zone.
    (6) In addition to those quality assurance measures specified in 
the methodology, the following quality assurance procedures must be 
followed:
    (a) If organisms are not cultured in-house, concurrent testing with 
reference toxicants must be conducted. Where organisms are cultured in-
house, monthly reference toxicant testing is sufficient.
    (b) If either of the reference toxicant tests or the effluent tests 
do not meet all test acceptability criteria as specified in the test 
methods manual, then the permittee must re-sample and re-test as soon 
as possible.
    (c) Control and dilution water should be receiving water, or 
salinity adjusted

[[Page 11899]]

lab water. If the dilution water used is different from the culture 
water, a second control, using culture water must also be used.
    (7) Accelerated Testing. (a) If chronic toxicity is detected above 
the permit limits, collection and analysis of one additional sample is 
required within two weeks of receipt of the test results.
    (b) If chronic toxicity is not detected in the sample required by 
Part III.F.7.a, the Permittee must notify the EPA and ADEC in writing 
of the results within fifteen (15) days of receipt of the results, and 
must discuss the cause of the exceedance, and the corrective actions 
which were taken.
    (c) If chronic toxicity is detected in the sample required by Part 
III.F.7.a., then the Permittee must conduct four bi-weekly tests over 
an eight week period. Accelerated testing must be initiated within 
fifteen (15) days of the receiving the sample results required by Part 
III.F.7.a.
    (8) Toxicity Reduction Evaluation (TRE). (a) If chronic toxicity is 
detected above the permit limits during accelerated testing, then in 
accordance with EPA/600/2-88/070, a toxicity reduction evaluation (TRE) 
must be initiated within fifteen days of this exceedance in order to 
expeditiously locate the source(s) of toxicity and evaluate the 
effectiveness of pollution control actions and/or in plant 
modifications toward attaining compliance.
    (b) If none of the four tests indicates toxicity, then the 
permittee may return to the normal testing frequency.
    (9) Toxicity Identification Evaluation (TIE). (a) If chronic 
toxicity is detected in any two of the four bi-weekly tests, the 
permittee must initiate a TIE to identify the specific chemical(s) 
responsible for toxicity (EPA/600/6-91/005F (Phase I), EPA/600/R-92/080 
(Phase II), and EPA-600/R-92/081 (Phase III).
    (b) If a TIE is triggered prior to completion of the accelerated 
testing, the accelerated testing schedule may be terminated, or used as 
necessary in performing the TIE.
    (10) Reporting. (a) The permittee must notify EPA and the State in 
writing within fifteen (15) days of receipt of the results of the 
exceedance of the permit limit, of the finding of the TRE/TIE or other 
investigation to identify the cause(s) of toxicity; actions the 
permittee has taken or will take to mitigate the impact of the 
discharge, to correct the noncompliance and to prevent the recurrence 
of toxicity; where corrective actions including a TRE/TIE have not been 
completed, an expeditious schedule under which corrective actions will 
be implemented; and if no actions have been taken, the reason for not 
taking action.
    c. Metals. The method detection limits and interim minimum level 
listed below are needed in order to determine whether or not violations 
of water quality are occurring at the point of discharge. In addition 
to the procedures approved under 40 CFR 136, the ICP-MS test procedure 
200.8 (``Methods for Chemical Analyses of Water and Wastes,'' EPA-600/
4-79-020) may be used for analysis of these samples.

under 40 CFR 136, unless other test procedures are specified here or 
elsewhere in this permit. Representative sampling requirements are 
discussed in Part III.A.
    Metals. For each discharge of well treatment, completion or 
workover fluids which is characterized as an acid job (strong or weak, 
including but not limited to hydrochloric or hydrofluoric acid, EDTA), 
samples of effluent must be taken for analyses of the following: 
cadmium, chromium, copper, lead, nickel and zinc. Analyses for total 
recoverable concentrations must be conducted and reported for each 
metal.

H. Other Discharge Limitations

1. Floating Solids, Visible Foam, or Oily Wastes
    There must be no discharge of floating solids or visible foam in 
other than trace amounts, nor of oily wastes which produce a sheen on 
the surface of the receiving water.
2. Surfactants, Dispersants, and Detergents
    The discharge of surfactants, dispersants, and detergents must be 
minimized except as necessary to comply with the safety requirements of 
the Occupational Health and Safety Administration and the Minerals 
Management Service. The discharge of dispersants to marine waters in 
response to oil or other hazardous spills is not authorized by this 
permit.
3. Applicable Marine Water Quality Criteria
    There must be no discharge of any constituent in concentrations 
which results in an exceedence of applicable marine water quality 
criteria at the edge of any permitted mixing zone.
4. Other Toxic and Non-conventional Compounds
    There must be no discharge of diesel oil, halogenated phenol 
compounds, trisodium nitrilotriacetic acid, sodium chromate or sodium 
dichromate.

I. Best Management Practices Plan Requirement.

1. Development
    The Permittee must develop a Best Management Practices (BMP) Plan 
which achieves the objectives and the specific requirements listed 
below.
    The Permittee must certify that its BMP Plan is complete, on-site, 
and available upon request to EPA . This certification must identify 
the NPDES permit number and be signed by an authorized representative 
of the Permittee. For new exploratory operations, the certification 
must be submitted no later than the written notice of intent to 
commence discharge (Part I.A.3). For existing dischargers, the 
certification must be submitted within one year of permit issuance.
2. Purpose
    The BMP Plan must be designed to prevent or minimize the generation 
and the potential for the release of pollutants from the facility to 
the waters of the United States through normal operations and ancillary 
activities.
3. Objectives
    The Permittee must develop and amend the BMP Plan consistent with 
the following objectives for the control of pollutants.
    a. The number and quantity of pollutants and the toxicity of 
effluent generated, discharged or potentially discharged at the 
facility must be minimized by the Permittee to the extent feasible by 
managing each influent waste stream in the most appropriate manner.
    b. The Permittee must establish specific objectives for the control 
of pollutants by conducting the following evaluations.
    (1) Each facility component or system must be examined for its 
waste minimization opportunities and its potential for causing a 
release of significant amounts of pollutants to waters of the United 
States due to equipment failure, improper operation, natural phenomena 
such as rain or snowfall, etc.
    (2) Where experience indicates a reasonable potential for equipment 
failure (e.g., a tank overflow or leakage), natural condition (e.g., 
precipitation), or other circumstances to result in significant amounts 
of pollutants reaching surface waters, the program should include a 
prediction of the direction, rate of flow and total quantity of 
pollutants which could be discharged from the facility as a result of 
each condition or circumstance.
4. Requirements
    The BMP Plan must be consistent with the objectives in Part 3 above 
and the general guidance contained in the publication entitled 
``Guidance Document for Developing Best Management Practices (BMP)'' 
(EPA 833-B-93-004, U.S. EPA, 1993) or any subsequent revisions to the 
guidance document. The BMP Plan must:
    a. Be documented in narrative form, and must include any necessary 
plot plans, drawings or maps, and must be

[[Page 11901]]

developed in accordance with good engineering practices. At a minimum, 
the BMP Plan must contain the planning, development and implementation, 
and evaluation/reevaluation components discussed in ``Guidance Document 
for Developing Best Management Practices (BMP)'' (EPA 833-B-93-004, 
U.S. EPA, 1993) or any subsequent revisions to the guidance document.
    b. Include the following provisions concerning BMP Plan review:
    (1) Be reviewed by plant engineering staff and the plant manager as 
warranted by changes in the operation or at the facility which are 
covered by the BMP.
    (2) Be reviewed and endorsed by the individuals responsible for 
development and implementation of the BMP plan.
    (3) Include a statement that the above reviews have been completed 
and that the BMP Plan fulfills the requirements set forth in this 
permit. The statement must be certified by the dated signatures of the 
individuals responsible for development and implementation of the BMP 
Plan.
    c. Establish specific best management practices to meet the 
objectives identified in Part 3 of this section, addressing each 
component or system capable of generating or causing a release of 
significant amounts of pollutants, and identifying specific 
preventative or remedial measures to be implemented.
5. Documentation
    The Permittee must maintain a copy of the BMP Plan at the facility 
and must make the plan available to EPA upon request.
6. BMP Plan Modification
    The Permittee must amend the BMP Plan whenever there is a change in 
the facility or in the operation of the facility which materially 
increases the generation of pollutants or their release or potential 
release to the receiving waters. The Permittee must also amend the 
Plan, as appropriate, when plant operations covered by the BMP Plan 
change. Any such changes to the BMP Plan must be consistent with the 
objectives and specific requirements listed above. All changes in the 
BMP Plan must be reviewed by the plant engineering staff and plant 
manager.
7. Modification for Ineffectiveness
    At any time, if the BMP Plan proves to be ineffective in achieving 
the general objective of preventing and minimizing the generation of 
pollutants and their release and potential release to the receiving 
waters and/or the specific requirements above, the permit and/or the 
BMP Plan must be subject to modification to incorporate revised BMP 
requirements.

IV. Recording and Reporting Requirements

A. Reporting of Monitoring Results

    The Permittee must summarize monitoring results each month on the 
Discharge Monitoring Report (DMR) form (EPA No. 3320-1). The Permittee

    d. The level established by the Director in accordance with 40 CFR 
122.44(f).

V. Compliance Responsibilities

A. Duty To Comply

    The Permittee must comply with all conditions of this permit. Any 
permit noncompliance constitutes a violation of the Act and is grounds 
for enforcement action, for permit termination, revocation and 
reissuance, or modification, or for denial of a permit renewal 
application. The Permittee must give reasonable advance notice to the 
Director of any planned changes in the permitted facility or activity 
that may result in noncompliance with permit requirements.

B. Penalties for Violations of Permit Conditions.

1. Civil and Administrative Penalties
    Any person who violates a permit condition implementing Sections 
301, 302, 306, 307, 308, 318, or 405 of the Act must be subject to a 
civil or administrative penalty, not to exceed the maximum amounts 
specified in Section 309(d) and 309(g) of the Act.
2. Criminal Penalties
    a. Negligent Violations. Any person who negligently violates a 
permit condition implementing Sections 301, 302, 306, 307, 308, 318, or 
405 of the Act must, upon conviction, be punished by a fine and/or 
imprisonment as specified in Section 309(c)(1) of the Act.
    b. Knowing Violations. Any person who knowingly violates a permit 
condition implementing Sections 301, 302, 306, 307, 308, 318, or 405 of 
the Act must, upon conviction, be punished by a fine and/or 
imprisonment as specified in Section 309(c)(2) of the Act.
    c. Knowing Endangerment. Any person who knowingly violates a permit 
condition implementing Sections 301, 302, 303, 306, 307, 308, 318, or 
405 of the Act, and who knows at that time that he thereby places 
another person in imminent danger of death or serious bodily injury, 
must, upon conviction, be subject to a fine and/or imprisonment as 
specified in Section 309(c)(3) of the Act.
    d. False Statements. Any person who knowingly makes any false 
material statement, representation, or certification in any 
application, record, report, plan, or other document filed or required 
to be maintained under this Act or who knowingly falsifies, tampers 
with, or renders inaccurate any monitoring device or method required to 
be maintained under this Act, must be punished by a fine and/or 
imprisonment as specified in Section 309(c)(4) of the Act.
    Except as provided in permit conditions in Part V.G., (``Bypass of 
Treatment Facilities'') and Part V.H., (``Upset Conditions''), nothing 
in this permit must be construed to relieve the Permittee of the civil 
or criminal penalties for noncompliance.

C. Need To Halt or Reduce Activity Not a Defense.

    It must not be a defense for the Permittee in an enforcement action 
that it would have been necessary to halt or reduce the permitted 
activity in order to maintain compliance with the conditions of this 
permit.

D. Duty To Mitigate

    The Permittee must take all reasonable steps to minimize or prevent 
any discharge in violation of this permit that has a reasonable 
likelihood of adversely affecting human health or the environment.

E. Proper Operation and Maintenance

    The Permittee must at all times properly operate and maintain all 
facilities and systems of treatment and control (and related 
appurtenances) that are installed or used by the Permittee to achieve 
compliance with the conditions of this permit. Proper operation and 
maintenance also includes adequate laboratory controls and appropriate 
quality assurance procedures. This provision requires the operation of 
back-up or auxiliary facilities or similar systems only when the 
operation is necessary to achieve compliance with the conditions of the 
permit.

F. Removed Substances

    Solids, sludges, filter backwash, or other pollutants removed in 
the course of treatment or control of water and wastewaters must be 
disposed of in a manner such as to prevent any pollutant from such 
materials from entering navigable waters.

G. Bypass of Treatment Facilities

1. Bypass Not Exceeding Limitations
    The Permittee may allow any bypass to occur that does not cause 
effluent limitations to be exceeded, but only if it also is for 
essential maintenance to assure efficient operation. These bypasses are 
not subject to the provisions of paragraphs 2 and 3 of this Part.
2. Notice
    a. Anticipated bypass. If the Permittee knows in advance of the 
need for a bypass, it must submit prior notice, if

[[Page 11903]]

possible at least 10 days before the date of the bypass.
    b. Unanticipated bypass. The Permittee must submit notice of an 
unanticipated bypass as required under Part IV.G. (``Twenty-four Hour 
Notice of Noncompliance Reporting'').
3. Prohibition of Bypass
    a. Bypass is prohibited, and the Director may take enforcement 
action against the Permittee for a bypass, unless:
    (1) The bypass was unavoidable to prevent loss of life, personal 
injury, or severe property damage;
    (2) There were no feasible alternatives to the bypass, such as the 
use of auxiliary treatment facilities, retention of untreated wastes, 
or maintenance during normal periods of equipment downtime. This 
condition is not satisfied if adequate back-up equipment should have 
been installed in the exercise of reasonable engineering judgment to 
prevent a bypass that occurred during normal periods of equipment 
downtime or preventive maintenance; and
    (3) The Permittee submitted notices as required under paragraph 2 
of this Part.
    b. The Director may approve an anticipated bypass, after 
considering its adverse effects, if the Director determine that it will 
meet the three conditions listed above in paragraph 3.a. of this Part.

H. Upset Conditions

1. Effect of an Upset
    An upset constitutes an affirmative defense to an action brought 
for noncompliance with such technology-based permit effluent 
limitations if the Permittee meets the requirements of paragraph 2 of 
this Part. No determination made during administrative review of claims 
that noncompliance was caused by upset, and before an action for 
noncompliance, is final administrative action subject to judicial 
review.
2. Demonstration of an Upset
    To establish the affirmative defense of upset, the Permittee must 
demonstrate, through properly signed, contemporaneous operating logs, 
or other relevant evidence that:
    a. An upset occurred and that the Permittee can identify the 
cause(s) of the upset;
    b. The permitted facility was at the time being properly operated;
    c. The Permittee submitted notice of the upset as required under 
Part IV.G., Twenty-four Hour Notice of Noncompliance Reporting; and
    d. The Permittee complied with any remedial measures required under 
Part V.D., Duty to Mitigate.
3. Burden of Proof
    In any enforcement proceeding, the Permittee seeking to establish 
the occurrence of an upset has the burden of proof.

I. Toxic Pollutants

    The Permittee must comply with effluent standards or prohibitions 
established under Section 307(a) of the Act for toxic pollutants within 
the time provided in the regulations that establish those standards or 
prohibitions, even if the permit has not yet been modified to 
incorporate the requirement.

J. Planned Changes

    The Permittee must give notice to the Director as soon as possible 
of any planned physical alterations or additions to the permitted 
facility whenever:
    1. The alteration or addition to a permitted facility may meet one 
of the criteria for determining whether a facility is a new source as 
determined in 40 CFR 122.29(b); or
    2. The alteration or addition could significantly change the nature 
or increase the quantity of pollutants discharged. This notification 
applies to pollutants that are subject neither to effluent limitations 
in the permit, nor to notification requirements under Part IV.I.
    The Permittee must give notice to the Director as soon as possible 
of any planned changes in process or chemical use whenever such change 
could significantly change the nature or increase the quantity of 
pollutants discharged.

K. Anticipated Noncompliance

    The Permittee must also give advance notice to the Director of any 
planned changes in the permitted facility or activity that may result 
in noncompliance with this permit.

VI. General Provisions

A. Permit Actions

    This permit may be modified, revoked and reissued, or terminated 
for cause. The filing of a request by the Permittee for a permit 
modification, revocation and reissuance, or termination, or a 
notification of planned changes or anticipated noncompliance, does not 
stay any permit condition.

B. Duty To Provide Information

    The Permittee must furnish to the Director, within the time 
specified in the request, any information that the Director may request 
to determine whether cause exists for modifying, revoking and 
reissuing, or terminating this permit, or to determine compliance with 
this permit. The Permittee must also furnish to the Director, upon 
request, copies of records required to be kept by this permit.

C. Other Information

    When the Permittee becomes aware that it failed to submit any 
relevant facts in a permit application, or that it submitted incorrect 
information in a permit application or any report to the Director, it 
must promptly submit the omitted facts or corrected information.

D. Signatory Requirements

    All applications, reports or information submitted to the Director 
must be signed and certified.
    1. All permit applications must be signed as follows:
    a. For a corporation: by a responsible corporate officer.
    b. For a partnership or sole proprietorship: by a general partner 
or the proprietor, respectively.
    c. For a municipality, state, federal, or other public agency: by 
either a principal executive officer or ranking elected official.
    2. All reports required by the permit and other information 
requested by the Director must be signed by a person described above or 
by a duly authorized representative of that person. A person is a duly 
authorized representative only if:
    a. The authorization is made in writing by a person described above 
and submitted to the Director, and
    b. The authorization specifies either an individual or a position 
having responsibility for the overall operation of the regulated

chemical feedstock, as opposed to the traditional base fluids such as 
diesel and mineral oil which are derived from crude oil solely though 
physical separation processes. Physical separation processes include 
fractionation and distillation and/or minor chemical reactions such as 
cracking and hydro processing. Since they are synthesized by the 
reaction of purified compounds, synthetic materials suitable for use in 
drilling fluids are typically free of polycyclic aromatic hydrocarbons 
(PAHs) but test sometimes report levels of PAH up to 0.001 weight 
percent PAH expressed as phenanthrene. Poly (alpha olefins) and 
vegetable esters are two examples of synthetic materials used by the

(alpha olefins) are synthesized from the polymerization (dimerization 
trimerization, tetramerization and higher oligomerization) of purified 
straight-chain hydrocarbons such as C6-C14 alpha 
olefins. Vegetable esters are synthesized from the acid-catalyzed 
esterification of vegetable fatty acids with various alcohols. The 
mention of these two synthetic fluid base materials is to provide 
examples, and is not meant to exclude other synthetic materials that 
are either in current use or may be used in the future. A synthetic-
based drilling fluid may include a combination of synthetic materials.
    78. ``Test fluid'' means the discharge which would occur should 
hydrocarbons be located during exploratory drilling and tested for 
formation pressure and content. This would consist of fluids sent

    80. A ``24-hour composite'' sample must mean a flow-proportioned 
mixture of not less than 8 discrete aliquots. Each aliquot must be a 
grab sample of not less than 100 ml and must be collected and stored in 
accordance with procedures prescribed in the most recent edition of 
``Standard Methods for the Examination of Water and Wastewater.''
    81. ``Unstable or broken ice conditions'' means greater than 25% 
ice coverage within a one mile radius of the discharge site after 
spring breakup or after the start of slush ice formation in the fall, 
but not stable ice.
    82. ``Upset'' means an exceptional incident in which there is 
unintentional and temporary noncompliance with technology-based permit 
effluent limitations because of factors beyond the reasonable control 
of the Permittee. An upset does not include noncompliance to the extent 
caused by operational error, improperly designed treatment facilities, 
inadequate treatment facilities, lack of preventive maintenance, or 
careless or improper operation.
    83. ``Waste stream'' means any non-de minimis stream of pollutants 
within the Permittee's facility that enters any permitted outfall or 
navigable waters. This includes spills and other

[[Page 11907]]

unintentional, non-routine or unanticipated discharges.
    84. ``Waterflooding discharges'' means discharges associated with 
the treatment of seawater prior to its injection into a hydrocarbon-
bearing formation to improve the flow of hydrocarbons from production 
wells, and prior to its use in operating physical/chemical treatment 
units for sanitary waste. These discharges include strainer and filter 
backwash water.
    85. ``Weekly average'' means the average of daily discharges over a 
calendar week, calculated as the sum of all daily discharges measured 
during a calendar week divided by the number of daily discharges 
measured during that week. For fecal coliform bacteria, the weekly

measured during a calendar week.
    86. ``Well completion fluids'' are salt solutions, weighted brines, 
polymers and various additives used to prevent damage to the well bore 
during operations which prepare the drilled well for hydrocarbon 
production. These fluids move into the formation and return to the 
surface as a slug with the produced water.
    87. A ``well treatment fluid'' is any fluid used to restore or 
improve productivity by chemically or physically altering hydrocarbon 
bearing strata after a well has been drilled.
    88. ``Workover fluids'' are salt solutions, weighted brines, 
polymers, or other specialty additives used in a producing well to 
allow for maintenance, repair of abandonment procedures. Drilling 
fluids used during workover operations are not considered workover 
fluids by definition. Packer fluids (low solid fluids between the 
packer, production string, and well casing) are considered to be 
workover fluids.
    89. ``XFA'' means x-ray fluorescence analysis.
    90. ``96-hour LC50'' means the concentration of a test material 
that is lethal to 50 percent of the test organisms in a toxicity test
