SECTION ONE
INTRODUCTION
The EPA proposed effluent limitations guidelines and standards for the offshore segment of
the oil and gas industry on August 26, 1985. The proposed regulations covered produced water,
drilling fluids, drill cuttings, produced sand, deck drainage, and well treatment fluids, as well as
sanitary and domestic wastes discharges. A Notice of Data Availability and Request for Comments
relating to the discharge of drilling fluids and drill cuttings was published on October 21. 1988.
In light of new information and data collected since 1985, the Agency has decided to re-
propose effluent limitations guidelines for the offshore oil and gas industry. This supplemental
cost-effectiveness (CE) report analyzes the cost-effectiveness of the alternative regulatory options
for drilling fluids, drill cuttings, and produced water. These options include effluent limitations
guidelines and standards based on BAT (Best Available control Technology economically
achievable) and NSPS (New Source Performance Standards), that are being considered under
authority of the Federal Water Pollution Control Act, as amended (the Clean Water Act). EPA
has identified several pollution control options, each with different levels of pollution abatement
and compliance cost. The CE analysis is a useful tool for evaluating the impact of regulatory
options on the removal of toxic pollutants. EPA's cost-effectiveness methodology is not intended
to analyze the removal of conventional pollutants (oil and grease, BOD and TSS). The removal of
conventional pollutants is not addressed in this report.
This report is primarily concerned with the total annualized cost incurred by the offshore .M!
and gas industry in complying with the regulations. The effectiveness measure used is pounds .•;
pollutant removed weighted by an estimate of their relative toxicity. The rationale for this
measure, referred to as "pound equivalents (PE) removed," is described later in this report
Section 2 discusses the background of the cost-effectiveness methodology employed -. :.~ %
report. Section 3 describes the alternative options under consideration, explains how the CE
calculated, and lists the pollutants included in the analysis. Section 4 presents the finding-
Additional information is included in the Appendix A.

SECTION TWO
BACKGROUND METHODOLOGY
Cost-effectiveness (CE) is defined as the incremental annualized cost of a pollution
control option in an industry or industry subcategory per incremental pound equivalent ot'
pollutant removed annually by that control option.
Cost-effectiveness analyses account for differences in toxicity among the pollutants with
toxic weighting factors. These factors are necessary because different pollutants have different
potential effects on human and aquatic life. For example, a pound of zinc in an effluent
stream has a significantly different potential effect than a pound of PCBs. Toxic weighting
factors for pollutants are derived using ambient water quality criteria and toxicity values. In the
majority of cases, toxic weighting factors are derived from chronic freshwater aquatic criteria.
In cases where a human health criterion has also been established for the consumption of fish,
then the sum of both the human and aquatic criteria are used in deriving toxic weighting
factors. However, in this study of an industry that discharges into the ocean, chronic saltwater
aquatic criteria are used wherever available. Chronic saltwater aquatic criteria are available tor
most of the pollutants considered in the analysis (see Tables 2-1 and 2-2). These toxic
weighting factors are then standardized by relating them to a particular pollutant.
Copper was selected as the standard pollutant for developing weighting factors since it is
a toxic metal pollutant and is commonly detected and removed from industrial effluents/ Some
examples of the effect of different aquatic and human health criteria on weighting factors are
shown in Table 2-3.
As indicated in Table 2-3, 18.2 pounds of copper pose the same relative hazard as one
pound of hexavalent chromium in the marine environment, since hexavalent chromium has a
salt water toxic weight approximately 18.2 times as large as the toxic weight of copper (i.e..
'EPA uses the old freshwater quality criterion for copper (5.6 ug/1) as the standardization
factor to retain comparability of the new CE results with values derived for previously regulated
industries. The toxic weighing factor for copper itself reflects the newer water quality criterion for
this pollutant

35.112 + 1.931). Benzene, on the other hand, is less potentially toxic than copper, as 53.6
pounds (1.931 + 0.036) of benzene would pose the same hazard as one pound of copper in the
marine environment.
The final weights are used to calculate the "pound equivalent" unit -- a standard
measure of toxicity. Pound equivalents are calculated as the number of pounds of pollutant
multiplied by the weighting factor. Thus, in CE analysis, the amount of pollutant removed by a
control option is weighted by its relative toxicity. Cost-effectiveness is calculated as the ratio of
incremental annual cost of an option to the incremental pound equivalents removed by that
option.
The pollutants included in CE analysis are the regulated pollutants and selected non-
regulated ones. Non-regulated pollutants are included because they can be removed incidentally
as a result of a particular treatment technology, even though they are not specifically limited.
(For example, in the case of drilling fluids and drill cuttings, some toxic metals such as arsenic
are removed from the marine environment when barging occurs, even though there is no
specific limitation on arsenic, and the cost-effectiveness reflects the removal of arsenic.) Some
of the factors considered in selecting non-regulated pollutants include toxicity, frequency of
occurrence, and amount of pollutant in the waste stream.
The data set for an industry-specific CE analysis contains the following information:
• Wastewater pollutants;
• The pollution control approaches identified by the Industrial Technology
Division;
• Annual volume of loadings by pollutant - currently, and at each BAT/NSPS
control level;
• Toxic weighting factor for each pollutant;
• Annualized costs for each control option (where results are adjusted to 1981
dollars for all industries).
Criteria or toxicity values have been developed for the priority pollutants and were
taken from data in the 1980 Ambient Water Quality Criteria Document (EPA-440/5-80 Series)

and revised Ambient Water Quality Criteria developed by EPA's Monitoring and Data Support
Division. Criteria for a few of the nonconventional pollutants were taken from the Quality
Criteria for Water. EPA- 440/9-76-023 and EPA 1976 (the Red Book).

SECTION THREE
COST-EFFECTIVENESS ANALYSIS METHODOLOGY
FOR DRILLING AND PRODUCTION WASTES
FOR THE OFFSHORE OIL AND GAS INDUSTRY
3.1 REGULATORY OPTIONS
The following regulatory options are evaluated for the control of drilling and production
wastes from offshore oil and gas projects. A more detailed discussion of the rationale for the
regulatory alternatives, as well as general industry economic and technical characteristics, appears
in the economic impact analysis, and in other items of the Record that support this proposed rule.
The Agency has identified five options for NSPS drilling fluids and drill cuttings, and three
options each for BAT and NSPS produced water. The term "option11 is used to refer to any of
several particular scenarios used for costing purposes. The options for drilling fluids and
produced water are discussed in turn below.
3.1.1 Options for Drilling Fluids and Drill Cuttings
Five options for BAT and NSPS were developed for the control of drilling fluids and drill
cuttings. The following requirements are included in some combination in the various options:
• No discharge of drilling fluids or drill cuttings.
• No discharge of diesel oil in detectable amounts, or no discharge of drilling fluids
and drill cuttings associated with oil-based drilling fluids.
• No discharge of "free oil" as measured by the static sheen test.
• Toxicity limitation as measured by a 96-hour LC-50 test.
3-1
-------
• Limitations on mercury and cadmium.
• Zero discharge of drilling fluids and drill cuttings based on water depth or distance
from shore. The zero discharge requirement is presumed to be met by barging the
Quids and cuttings to shore for disposal. The August 26, 1985 proposal based part
of the requirements on water depth, not distance from shore.
These requirements have been combined into five regulatory options which are the focus of the
cost-effectiveness analysis:
Zero Discharge - all fluids and cuttings are barged to shore for treatment and
disposal.
4-Mile Barge: 1.1 Other - fluids and cuttings from wells drilled within 4 miles of
shore are barged to shore for disposal and where Quids and cuttings from wells
beyond 4 miles of shore must meet a 1,1 mg/kg limit on mercury and cadmium
content, pass the toxicity test, substitute mineral oil for diesel oil, and pass the
static sheen test. Under this option, an exemption from mandatory barging is
made for Alaska. Fluids and cuttings must meet a 1,1 mg/kg limit on mercury and
cadmium content, pass the toxicity test, substitute mineral oil for diesel oil, and
pass the static sheen test.
4-Mile Barge: 5.3 Other - Quids and cuttings from wells drilled within 4 miles of
shore are barged to shore for disposal and where Quids and cuttings from wells
beyond 4 miles of shore must meet a 5,3 mg/kg limit on mercury and cadmium
content (respectively), pass the toxicity test, substitute mineral oil for diesel oil,
and pass the static sheen test Under this option, an exemption from mandatory
barging is made for Alaska. Fluids and cuttings must meet a 5,3 mg/kg limit on
mercury and cadmium content, pass the toxicity test, substitute mineral oil for
diesel oil, and pass the static sheen test
1.1 All - all Quids and cuttings must meet a 1,1 mg/kg limit on mercury and
cadmium content, pass the toxicity test, substitute mineral oil for diesel oil, and
pass the static sheen test
53 All - all Quids and cuttings must meet a 5,3 mg/kg limit on cadmium and
mercury content (respectively), pass the toxicity test, substitute mineral oil for
diesel oil, and pass the static sheen test
Although the economic impact analysis investigates the potential impacts for the five
options, only options with barging are considered in the cost-effectiveness analysis. This is
because barging passes the BCT test; i.e. the two tests for the cost-reasonableness for controls on
3-2
-------
conventional pollutants such as total suspended solids, oil, and grease (see Development
Document for further discussion). The options considered in the cost-effectiveness analysis for
BAT and NSPS cannot be less stringent than that chosen for BCT.
3.1.2 Options for Produced Water
For both BAT and NSPS produced water, the options are distinguished by the method of
treatment and disposal utilized, and by whether the platform is within 4 miles of shore. Two
disposal alternatives are considered:
• Offshore injection of produced water;
• Filtration of produced water prior to offshore disposal
The options which are considered are described as follows:
Zero Discharge - All structures would be required to dispose of produced water
through injection. Under this approach, structures beyond 4 miles of shore are
assumed to inject offshore. For structures within 4 miles of shore, the option of
piping the effluent to shore for injection has also been costed. Where piping to
shore is found to be more economical, that option is assumed to be chosen.
Otherwise, the structure is assumed to inject offshore;
All Filter - Filtration and discharge of produced water for all structures;
4-Mile Filter. BPT Other - Filtration and disposal for structures within 4 miles of
shore with BPT disposal for other structures.
3.2 DEVELOPMENT ASSUMPTIONS AND SENSITIVITY ANALYSIS
The costs and removals associated with each option are affected by several parameters,
such as how many wells and platforms are forecast and the pollutants found in the effluents. For
drilling fluids and drill cuttings, two projections were made for the $21/bbl oil price scenario.
"Unrestricted development" assumes that all possible activity in each region takes place.
"Restricted development" takes into account the recent bans on offshore leasing and drilling m
3-3
-------
the PaciGc and the Atlantic. These terms are synonomous with the terms "Unconstrained" and
"Constrained", respectively, that are used in the preamble to the rule.
For produced water, two types of filters are investigated. Granular filters are assumed to
remove benzene, 2-4 Dimethylphenol, ethylbenzene, naphthaline, toluene, Bis(2-Ethylhexyl)
phthalate, and phenol only. Membrane filters are assumed to remove all pollutants listed in Table
2-2. Different costs are associated with each type of filter.
Variations in the pace of future development and the pollutants considered result in
several cost-effectiveness analyses being presented for each effluent.
3 J ANALYTICAL APPROACH
The annual pollutant removals and associated costs in 1986 dollars for each option and for
each geographic region were developed by EPA's Industrial Technology Division. For each of the
options considered here, the pound equivalents of pollutants removed were obtained by
multiplying the pounds of each pollutant removed annually by that pollutant's toxic weighing
factor and summing the pound equivalents for each approach. Regional totals were then summed
to obtain the national totals. Removals were calculated relative to the baseline defined by current
practices, i.e. they represent the incremental quantities of pollutants which would be removed.
Because the removals are calculated relative to the current baseline, options for drilling
fluids and drill cuttings which require barging may show negative removals for some pollutants.
This is because current practices include the substitution of more expensive (but less toxic)
mineral oil for diesel oil Under the barging requirement, operators are assumed to no longer
substitute mineral for diesel oil (since the effluent must be barged anyway), with the result that,
relative to current practices, some pollutant removal levels would be lower. Current practices in
some regions also require the barging of fluids that fail the toxicity test These removals must be
subtracted from those options with mandatory barging requirements since they would occur
regardless under current practices.
3-4
-------
Table 3-1 shows the removals for the zero discharge option for NSPS drilling fluids and
drill cuttings in the Gulf of Mexico. Tables showing pollutant removals for each of the three
effluent groups (NSPS drilling fluids and drill cuttings, BAT produced water, NSPS produced
water) under all options are found in Appendix A, The costs for monitoring, barging and land
disposal of drilling and production wastes and for filtration and injection of production'wastes
were calculated for each regulatory option (see the Development Document for details). To
enable comparisons between industries, these costs were converted to 1981 dollars by dividing by
a factor of 1.21 (based on the change in the Construction Cost Index from 1981 to 1986; see
Engineering News Record. March 17, 1988).
Following standard procedures for the Agency's cost-effectiveness analyses, the options
were ranked in order of increasing stringency (i.e., increasing pound equivalents removed). The
incremental cost-effectiveness of each option was calculated by the following equation:
= ATCt - ATC*.,
- PE,.,
where:
CEk = cost-effectiveness of Option K;
= annualized treatment cost of Option K;
= pound equivalent removed at Option K.

Note: Negative values refer to pollutants for which operators are either required to or have incentives
to Unit under current practices. Under the zero discharge requirement, all drilling fluids and
drill cuttings would be barged to shore for disposal. Operators who had previously substituted
mineral for diesel oil. therefore, might revert to diesel oil, with the result that removals
of diesel oil constituents would be negatively affected.

SECTION 4
COST-EFFECTIVENESS RESULTS
Cost-effectiveness (CE) analysis was performed for each of the drilling and production
effluents. Section 4.1 discusses CE for NSPS drilling fluids and cuttings. Section 4.2 covers CE
for BAT Produced Water, and Section 4.3 considers CE for NSPS Produced Water.
4.1 Cost-Effectiveness for NSPS Drilling Fluids and Drill Cuttings
Table 4-1 shows the cost-effectiveness analysis results for NSPS drilling fluids and drill
cuttings under the $21/bbl restricted development scenario. Cost-effectiveness is S22 per pound
equivalent (PE) for the 4-Mile Barge; 1,1 Other option, S112/PE for the 4-Mile Barge; 5,3 Other
option, and S345/PE for the Zero Discharge option.
A sensitivity analyses was performed for the NSPS drilling fluids and drill cuttings
regulations. Table 4-2 shows the cost-effectiveness for the $21/bbl unrestricted development
scenario. Cost-effectiveness is S28/PE for the 4-Mile Barge; 1,1 Other option, S127/PE for the 4-
Mile Barge; 5,3 Other option, and $265/PE for the Zero Discharge option. Tables 4-3 and 4-4
show the effects of alternative oil price scenarios. The cost-effectiveness for the 4-Mile Barge;
1,1 Other option ranges from S21/PE to S35/PE under these scenarios. Figure 4-1 summarizes
the cost-effectiveness under all four scenarios. Pollutant removals for the $21/bbl scenarios are
given in Tables A-l through A-12.
4.2 Cost-Effectiveness for BAT Produced Water
CE analysis was performed for each of the three options for BAT produced water with
both the membrane and granular Glter cost assumptions. Table 4-5 summarizes the results of this
cost-effectiveness under the membrane filter costs assumption, and including all of the pollutants

identified in Table 2-2. Cost-effectiveness is S56/PE for the Zero Discharge option. S60/PE for
the 4-Mile Filter; BPT Other option, and S66/PE for the All Filter option. Figure 4-2
summarizes this information.
Table 4-6 summarizes the cost-effectiveness on BAT produced water assuming granular
filter costs. This CE analysis includes a subset of the pollutants listed in Table 2-2. Cost-
effectiveness is S2,351/PE for the 4-Mile Filter: BPT Other option, $2,376/PE for the All Filter
option, and $6,815/PE for the Zero Discharge option. Figure 4-3 summarizes this information.
The pollutant removals for BAT produced water analyses (both granular and membrane) can be
found in Tables A-13 through A-18.
4J Cost-Effectiveness for NSPS Produced Water
Cost-effectiveness analyses was performed for each of the three control options for NSPS
produced water under each of the following assumptions:
• $21/bbl - Restricted Development, Membrane Filter Costs
• $21/bbl - Restricted Development, Granular Filter Costs
• $21/bbl - Unrestricted Development, Membrane Filter Costs
• $21/bbl - Unrestricted Development, Granular Filter Costs
• $15/bbl - Restricted Development, Membrane Filter Costs
• $15/bbl - Restricted Development, Granular Filter Costs
• $32/bbl - Unrestricted Development, Membrane Filter Costs
• $32/bbl - Unrestricted Development, Granular Filter Costs
They are summarized in Tables 4-7 through 4-14, respectively.
The cost-effectiveness for the 4-Mile Filter: BPT Other option is S63/PE under the most
reasonable scenario ($21/bbl - restricted development, membrane filter costs) and ranges from
S29/PE to S100/PE under the other membrane filter scenarios. For the All Filter option the cost-
effectiveness is S53/PE under the first scenario and ranges from S44/PE to S52/PE under the

other scenarios. The cost-effectiveness of the Zero Discharge option under the membrane filter
assumption is S32/PE under the first scenario, and ranges from S21/PE to S33/PE under the other
membrane filter scenarios.
Under the second scenario ($21/bbl - restricted development, granular filter costs), the
cost-effectiveness for the 4-Mile Filter; BPT Other option is 51,611/PE, and ranges from S800/PE
to Sl,589/PE under the other granular filter scenarios. For the All Filter option, the cost-
effectiveness is S844/PE under the $21/bbl - restricted development scenario, and ranges from
S707/PE to S816/PE for the other granular scenarios. The cost-effectiveness of the Zero
Discharge option is $4,458/PE under the second scenario, and ranges from $3,308/PE to
$4,402/PE under the other granular filter scenarios.
Figure 4-4 displays the cost-effectiveness under the four scenarios which assume
membrane filter costs. (This includes removals of all pollutants listed in Table 2-2). Figure 4-5
displays the cost-effectiveness of the three regulatory options under the four scenarios which
assume granular filter costs, and therefore include a removals of a limited number of pollutants.
The pollutant removals for NSPS produced waters can be found in Tables A-19 through A-30.
4.4 Summary
Table 4-15 compares the range in cost-effectiveness for the offshore oil and gas industry
effluents to the cost effectiveness of BAT regulations for other industries. New wells drilled on
existing platforms fall under BAT regulation. Since most development wells are drilled within a
year or two of platform installation, and since the cost-effectiveness analysis is based on the
average annual number of wells projected to be drilled between 1986 and the year 2000, BAT
regulations on drilling fluids and drill cuttings would affect only a small portion of these offshore
oil and gas wells. All existing facilities would be affected by BAT requirements for produced
water.
Table 4-16 presents the range of cost-effectiveness for offshore oil and gas effluents
compared to the cost effectiveness of NSPS regulations for other industries. All costs shown are

in 1981 dollars. The major impact of regulations on drilling fluids and drill cuttings for the
offshore oil and gas industry would occur under NSPS because NSPS cover exploratory wells and
all wells drilled on new platforms. Produced water from new projects would be affected by NSPS
regulations. The effect of the combined costs for NSPS regulations on multiple waste streams --
drilling fluids, drill cuttings, and produced water -- has been investigated in the economic impact
analysis.
