  EXECUTIVE SUMMARY
  This report provides an overview of the benefits analysis of the effluent limitation
  guidelines for offshore oil and gas facilities. Regulatory options were evaluated for two
  wastestreams: (1) drilling fluids (muds) and cuttings; and (2) produced water.

  The analysis focuses on the human health-related benefits of the regulatory options
  considered.  These health risk reduction benefits are associated with reduced human
  exposure to various carcinogenic and noncarcinogenic contaminants, including lead, by
  way of consumption of shrimp and recreationally caught finfish from the Gulf of Mexico
  Most of the health-risk reduction benefits analysis is based upon a previous report
  (RCG/Hagler, Bailly, January 1991), developed in support of the proposed rulemaking.~
  Recreational, commercial, and nonuse benefits have not been estimated for these
  regulations,  due to data limitations and the difficulty of estimating these values for
  effluent controls in the open-water marine environment.

 DRILLING  FLUIDS AND CUTTINGS

 Benefits were estimated for several regulatory options  beyond baseline practices (BPJ or
  dirty" bante muds).  Estimates were prepared for Gulf of Mexico locations only  These
 options include:   .

           3 Mile Gulf/California.  Zero discharge (i.e., the transport of muds and
           cuttings to shore for appropriate land-based waste management and disposal)
           for all platforms within three miles of shore. Under this  option, Best
           Available Technology (BAT), consisting of using "clean" barite drilling fluids,
           applies to all platforms beyond  three miles of shore.  Alaska is exempt from
           the zero discharge requirement.

      *     8  Mile Gulf/3 Mile California.  Zero discharge for platforms within eight miles
           of shore, and BAT for platforms beyond.  California and  Alaska must meet
           the same requirements .as in the 3 Mile Gulf/California option.

          Zero Discharge Gulf/California   Zero discharge for all platforms. Alaska is
          exempt, but must meet the same requirements as in the 3 Mile Gulf/California
          option.

The estimated benefits of these options are predominantly derived from reducing the
amount of lead in edible shrimp tissue harvested from platform-impacted waters of the
Gulf (over 15 million kilograms per year).  Lead concentrations in edible fish tissue are
based on water column and sediment pore  water concentrations (omitting uptake via
sediment or food chain).  Additionally, benefits associated with decreased  carcinogenic

risks were estimated.  For both risk categories, benefits were estimated using a saltwater
leach scenario and an alternative, pH-dependent leach scenario.

Benefits Estimation Methodology: Drilling Fluids and  Cuttings

Lead-Related Benefits.  All of the lead-related benefits analysis draws upon, and is
consistent with, the Agency's previous research on lead.  These previous findings are
reflected in Agency analyses and documents prepared for the lead phasedown in
gasoline, the lead in drinking water rulemaking, and the sludge disposal program.

Major toxic effects of lead include inhibition of heme synthesis, kidney disfunction, and
damage to the central nervous system.  Broad symptoms include increased blood pressure
and reduced  learning ability.  Based on previous agency research relating lead intake to
selected adverse health effects, reductions in the number of cases of these health
endpoints were quantified for the offshore oil and gas effluent guidelines options. These
lead-related benefits include (1) decreased infant mortality;  (2) reduced I.Q. impairments
in children; and (3) reduced risks of heart disease, strokes, hypertension and death in
males between  40 and 59 years of age.

To estimate these benefits, lead concentrations in edible shrimp tissue and recreationally
caught finfish tissue, and estimates of the shrimp and finfish harvests impacted by
platform operations, were prepared for each drilling fluids and cuttings regulatory option
(Avanti Corporation, 1992).

The platform-impacted Gulf shrimp harvest was allocated across the estimated 50 million
Americans who consume shrimp.  The impacted recreational finfish harvest was allocated
across the estimated 1.7 million individuals consuming recreationally-caught Gulf finfish.
Estimates of human exposure were made at four intake levels that reflect the distribution
of shrimp or  finfish consumption levels across the population of shrimp or finfish eaters
(e.g., individuals who consume relatively low amounts of impacted shrimp, versus those
who eat relatively high levels of shrimp).

Seafood consumption levels, coupled with the  option-specific lead concentrations in
edible shrimp or finfish tissue, provide estimates of the daily lead intake via shrimp and
finfish for each exposure group (for each regulatory option). Using age-specific
adsorption factors to distinguish lead uptake levels in children versus adults, lead intake
levels were transformed into estimates of lead uptake. Using prior Agency lead research,
lead uptake was used to estimate  changes in the distribution of blood lead levels (PbB)
above the baseline distribution (of no shrimp-related or finfish-related lead exposure).

  Within each exposure group, the populations were distributed across age and sex
  categories for which risk reduction analysis can be performed:  children, adult males, and
  pregnant women (whose blood lead level affects the risk of infant mortality):

       *    For the children within each exposure group, established Agency research
            linking elevated blood lead levels to IQ impairments was used to estimate the
            option-specific reductions in: 1) the total level of IQ point decrements, and 2)
            the number of children with IQ levels below 70.

       •>    For the expected number of pregnant women within each exposure group
            established Agency research linking elevated blood lead levels to reduced fetal
            birth weight and, hence, increased infant mortality was used to estimate the
            option-specific reductions of infant deaths.

       -    For the expected number of males between the ages of 40 and 59 within each
            exposure group, established Agency research was used that links:  1) elevated
            blood lead levels to hypertension and, subsequently, 2) the increased risk of
            strokes, cardiovascular heart disease (CHD), and premature fatality due to
            hypertension.  These results were used to estimate the option-specific
            reductions of strokes, CHD events, and death in the male population between
            40 and 59 years of age.

 The estimated number of reductions in health effects (cases avoided) at each regulatory
 option » shown m Table  ES-1.  These results reflect the impact of lead exposure due to
 impacted shrimp consumption (estimated lead-related exposures via finfish consumption
 are so low that no estimable lead-related benefits can be attributed to the regulatory
 options).                                                               "     y

 Cancer Risk Reduction Benefits  In conformant with standard Agency risk assessment
 procedures for carcinogens, excess cancer cases were estimated by multiplying the
 ainn? forSe^S?KSUI!  leVC1^ (3t 6ach °pti°n) by the establis«ed Agency carcinogenic
 slope factor (CSF), by the total exposed population.

 Results: Drilling Fluids and Cuttings

 In Table ES-2,  the monetized values of lead-related benefits are displayed for the
 selected option (3 Mile Gulf/California). The dollar values assigned to each health effect
 are consistent with EPA's  other lead benefits analysis (e.g., the RIAs for the drinking
 water and sludge  rulemakings). As shown in Table ES-3, most of the benefits are
 obtained at the three-mile barge option, with small incremental benefits realized at more
 stringent options.  All of the benefit levels shown in these tables are related to the use of
 a saltwater leach scenario  for calculating the bioavailability of lead in the marine
environment The alternative  scenario evaluated (using a pH-dependent leach rate to

 degree, and the resulting benefit levels would increase by more than a factor of six times
 greater than the values shown here.

 The total monetized benefits of the options for drilling muds and cuttings are shown in
 Table ES-4. In addition to the lead-related benefits described above, the values also
 reflect modest reductions in cancer risk as associated with arsenic.  .These "total" benefits
 are understated due to the omission of several potentially significant benefits.  Omitted
 benefits include, but are not limited to:  (1) Adverse health effects from lead in women
 and in men below the age of 40 or over the age of 59; (2) Adverse lead-related health
 effects other than the endpoints quantified; (3)  Lead-related exposure associated with
 shrimp or finfish uptake of lead through the sediments directly, or indirectly, through the
 food chain; (4) Recreational and commercial fishery improvements; (5) ecologic benefits;
 and (6) nonuse values.

PRODUCED WATER

The benefits associated with produced water at existing or new sources (NSPS) are
related to three_regulatory options:

     >•    Flotation All  Improved gas flotation for all platforms (BAT).

     >    Zero 3 Miles Gulf and Alaska.  Zero discharge (re-injection) at platforms
          within three miles of shore, and BAT for platforms beyond three miles. BAT
          required for California wells.

     >.    Zero Discharge Gulf and Alaska. Zero discharge for all platforms except
          California.  BAT required for California wells.

Benefit estimates were prepared for Gulf of Mexico locations only. The methodology for
estimation of benefits associated with the produced water options is the same as that
described above under Drilling Fluids and Cuttings (except that shrimp-related exposures
could not be estimated for produced water).

 The quantified and monetized benefits are based on reduced human health risks by way
 of exposure to selected carcinogens (arsenic, benzene and benzo(a)pyrene) and lead
 through the consumption of recreationally harvested finfish (shrimp uptake of
 contaminants from the produced water wastestream could not be estimated).  The
 estimated benefit levels are relatively modest, as shown in Tables ES-5 for existing
 platforms (BAT) and NSPS. It is important to note, however, that these quantified and
 monetized values omit several important benefits.  These omitted benefits include (but
 are not limited to):  (1) Lead related risk reductions for women (all ages) and for men
 other than those between the ages of 40 and 59; (2) Lead-related health effects other
 than those evaluated; (3) Lead-related exposure associated with shrimp or finfish uptake
 of lead through sediments directly, or indirectly through the food chain; (4) Recreational
 and commercial fishery benefits; and (5) Nonuse values and ecologic benefits  that may be
 associated with the regulatory options.

 CONCLUSIONS

 The benefits of the offshore oil and gas effluent guidelines appear to be significant, with
 the monetized human  health benefits for the selected options for drilling fluids and
 cuttings, and produced water, amounting to between $30 million and $111 million per
 year. Virtually all of these benefits arise from estimated reductions in a limited range of
 adverse health effects associated with lead exposure.

 While the estimated human health benefits are significant in their own right, it is
 important to consider that the estimated monetized benefits for both the muds and'
 cuttings and produced  water wastestreams are appreciably limited by the omission of
 several potentially significant types of benefits that could not be monetized due to current
 limitations of thp data  and quantitative methods. Table ES-6  provides an overview of the
 types of benefits that were monetized as well as those potential benefits that could not be
 assessed reliably in quantitative and/or monetary terms. This indicates the extent to which
 there are many potentially significant benefits that are not included in the monetary
 benefits assessment.

 1.0   INTRODUCTION

 1.1    SCOPE AND PURPOSE OF THIS BENEFITS ANALYSIS REPORT

 This report represents an economic benefits analysis for the effluent limitation guidelines
 for offshore oil and gas facilities. The benefits analysis specifically addresses the health
 risk reduction benefits attained from applying regulatory options for the drilling fluids
 and produced water waste-streams.

 This analysis of the reduced human health risks associated with the pollutant removals is
 based on the consumption of (i) recreationally-caught finfish species by sport anglers in
 the Gulf of Mexico (for both the muds and cuttings and produced water wastestreams);
 and (ii) shrimp commercially harvested in impacted Gulf waters and consumed by the
 general public (for drilling fluids and cuttings only). This report is based extensively on
 the methodology and  analysis conducted for regulatory options evaluated in previous
 rulemaking efforts, as described in greater detail in RCG/Hagler, Bailly (January 1991).
 The analysis described below applies this previously conducted research to the current set
 of regulatory options.   In addition, the analysis has been revised as described below to
 reflect updated fish harvest data and health effects valuation insights.


 1.2    OUTLINE OF THE REPORT

 The outline of this report is as follows: Section 2.0 provides an overview of the
 methodology.  Section 3.0 provides a summary of the findings for the drilling fluids
 (muds) and cuttings regulatory options. Section 4.0 provides a summary of findings for
 the regulatory options associated with the produced water wastestream at existing
 platforms, and Section 5.0 provides produced water results for new sources (NSPS).
 Section 6.0 offers a summary and conclusions.  Finally, appendices provide detailed
 results for each wastestream and regulatory option.

  2.0   OVERVIEW OF METHODOLOGY
  2.1
INTRODUCTION AND DISCUSSION OF GENERAL METHODOLOGY
  The methodology employed for this analysis is identical to that employed in the benefits
  analysis that originally accompanied the proposed rulemaking, as described in the report,
  The Economic Benefits of Proposed Effluent Limitation Guidelines for Offshore Oil and
  Gas F*a/^(RCG/Hagler, Bailly, Inc., Final Report, January 24, 1991). In the analysis
  changes in effluent concentrations are translated into changes in fish tissue  concentrations
  for the applicable pollutants (this analytic step is performed by Avanti Corporation
  (Avanti, 1992)).  These changes in fish tissue contaminant concentrations are then
  translated, via exposure assessments for shrimp eaters and recreational anglers to
  changes in human intake of the contaminants. Reductions in health risks are then
  characterized using Agency-established dose-response functions. The contaminants
  addressed in this supplemental analysis, and the dose-response relationships which were

 The economic benefits assessment is organized by benefit category. Typically, the largest
 benefits of regulations that reduce pollutant loadings to surface waters are related to
 recreation values.  In this case, however, because data do not exist to estimate such
 benefits, reductions in human health risks appear to  be the most significant monetizable
 benefit category^ Therefore,  much of the benefits analysis pertains to the risk

             Concentrations of Contaminants in Edible Seafood Tissue
             Lead concentrations in edible shrimp and finfish tissue, and estimates of
             the shrimp and finfish harvest impacted by platform operations, were
             prepared for each muds and cuttings regulatory option by Avanti
             Corporation (1992). No credible pathway analysis could  be developed to
             link the produced water wastestream to lead levels in shrimp.

             Exposure Assessments for Human Intake of Contaminants

             Given the pollutant concentrations in edible fish tissues, for estimated
             portions of the Gulf catch impacted, the analysis generates exposure
             scenarios that reflect Most Exposed Individual (MEI) and "average" fish
             consumption patterns,3 explained in greater detail below.  The exposure
             scenarios are based on EPA guidance on risk assessment for ingestion of
             tainted fish ("Assessing Human Health Risks from Chemically
             Contaminated Fish and Shellfish: A Guidance Manual," US EPA/OWRS,
             1989a), food consumption data from the U.S. Department of Agriculture
             ("Food Consumption, Prices and Expenditures," USDA/ERS,  1985), and
             information obtained from other relevant sources.

             Dose-Response Relationships

             The "doses" of pollutants, as derived from the exposure assessment, are
             then compared tp standard dose-response measures. For carcinogens, unit
             slope measures are used to estimate excess lifetime cancer risks per
             exposed individual, and the expected number of excess cancers over the
             applicable population. For noncarcinogens. exposures are compared to
             oral reference doses (oral RfDs) to indicate the percentage of dose from
             this source relative to  the "threshold" dose.4  Carcinogenic unit slope
             factors and oral RfDs for noncarcinogens are derived from EPA's
             Integrated Risk information System (IRIS) database, which represents the
             Agency consensus view of the health end-points and potency for the
    3 An intermediate exposure scenario, which is defined as a "quasi-MEI," is also developed and used to
illustrate the impact of several regulatory options.  This scenario is explained in greater detail in subsequent
chapters of this report  For the lead analysis, a distribution of four exposure levels is developed, as
described below.

    4 Technically, the oral RfDs are not "thresholds" in a strict sense, because there is considerable
uncertainly as to whether any dose level is "safe." Rather, oral RfDs reflect the level of long-term daily
exposure at which there is concern regarding possible adverse chronic health effects.

             contaminants.  For contaminants not present in IRIS, EPA's Health Effects
             Assessment Documents are used.

             For lead, a special procedure must be adopted, because there is no
             Agency-recognized threshold (oral RfD) for its noncarcinogenic health
             risks.  For lead, the Agency-approved procedure is to calculate the
             concentrations of lead in blood. Blood lead (PbB)  distributions are
             estimated based on EPA's Air Quality Criteria Document for Lead (as
             developed by the Office of Research and Development), and OAQPS' Staff
             Report on exposure analysis methods for lead (USEPA (1989b), which was
             reviewed and approved by the SAB's Clean Air Science Advisory
             Committee, and used for the lead in drinking water regulations).  The
             results are used to indicate average (geometric mean) PbB levels, as well as
             PbB levels at specified percentiles of the population (for both children and
             adults).  All of the lead-related benefits analysis draws upon, and is
             consistent with, the Agency's previous research on lead (e.g., USEPA, 1985,
             1986,  1989a, 1989b).  These previous findings are reflected in Agency
             analyses and documents prepared for the lead phasedown in gasoline, the
             lead in drinking water rulemaking, and the  sludge disposal program.

             Derivation of Anticipated Health Impacts

             Finally, the actual risk characterization is made by combining exposure
             estimates with dose-response information described above to derive
             anticipated health impacts  to each target population stemming from the
             discharge.
2.2   EXPOSURE SCENARIOS

2.2.1  Seafood Consumption Levels

As in the previous analysis (RCG/Hagler, Bailly, January 1991), three human exposure
scenarios have been developed and analyzed: (1) average, (2) Most Exposed Individual
(MEI), and (3) "quasi-MEI"  levels of exposure.5

      +      The average exposure scenario conforms to a mass balance between
             landings of contaminated seafood and the estimated total number of people
             exposed.  This is derived by dividing impacted landings (recreational finfish
    5  As detailed in Section 2.2.2 below, lead-related risks were based on a more refined distribution of
exposure levels.

              and commercial shrimp) over the number of people that participate (i.e.,
              the number of people who are Gulf recreational anglers, or American
              shrimp consumers).  In all of the average exposure scenarios developed, the
              mass balance approach is important in that it maintains a physical
              consistency between the amount of tainted seafood landed and the resulting
              level of human intake and exposure.

              For finfishT the average daily intake level of rig-impacted fish, under muds
              and cuttings at baseline, is 0.98 grams per day.  This is derived as 320,880
              kg of rig-impacted fish landed per year (Avanti Corporation, 1992) divided
              by 900,000 recreational anglers,6 divided by 365 days per year.  For
             produced water, the average daily intake of rig-impacted fish at baseline is
              8.14 g/day per person (2.674 million kg edible fish tissue landed (Avanti,
              1992), divided by 900,000 anglers, divided by 365 days per year).
                               i
              For shrimp, the average baseline muds and cuttings intake amounts to 0.82
              g/day per person.  This is derived as  15.03 million kg rig-impacted shrimp
              landed per year (Avanti Corporation, 1992), divided by 50 million
              American  shrimp consumers (RCG/Hagler, Bailly, 1991), divided by 365
              days per year. As with the finfish consumption levels, the intake of rig-
              impacted shrimp varies according to whether a given regulatory option
              affects only a portion of the  platforms and, hence, only a portion of the
              baseline impacted shrimp harvest.

              The Most  Exposed Individual (MEI) exposure is based on an intake of rig-
              impacted seafood  of 284 g/day, as consistent with EPA's Risk Assessment
              Gpjdance for Superfund (1989).  This reflects the upper 95% confidence
              limit on seafood consumption per meal. Thus, the MEI reflects those
              individuals who, for every day of their lives, eat one  large meal per day of
              rig-impacted seafood.

              The quasi  MEI exposure is intended  to reflect a high consumption scenario
              that is more plausible than the MEI (which assumes that the main protein
              source for  the individual, for every day of his/her life, is a large portion of
              rig-impacted seafood).  A 45 g/day consumption value is used here as a
    6 • As described later in the text, an estimate 900,000 is used to reflect the number of individuals
potentially exposed by way of recreationally harvested finfish from the offshore Gulf, within three miles of
Shore. This includes the anglers themselves plus other individuals with whom the catch may be shared.
These rig-impacted average fish consumption values change for regulatory options defining a different
number of miles from shore as the zero discharge/BAT cut-off point (because greater or fewer rigs and,
hence, greater or fewer fish and anglers are impacted).
RCG/Hagler, Bailly, Inc.

              quasi-MEI measure, which approximates the average for an avid
              recreational angler.  This is essentially a scenario for someone who eats one
              large seafood-based meal every other day of his/her life, and assumes that
              half of the seafood consumed is rig-impacted.


 2-2-2   Using the Exposure Scenarios in Calculating Risk Reduction Benefits

 Carcinogenic and Noncarcinogenic Risks (Apart from Lead)

 For carcinogenic risk levels, the mass balance-derived average exposure levels are used to
 estimate both average exposure and the size of the exposed human population.  As noted
 above, the mass balance approach maintains a physical consistency between the amount
 of tainted fish landed and the resulting level of human intake and exposure.

 The quasi MEI and MEI scenarios are not appropriate for estimating numbers of excess
 cancer cases. Instead, they are used for indicating the individual cancer risk levels faced
 by those individuals who fit a given exposure pattern. They also  are used in developing
 "hazard indices" for noncarcinogens (comparisons of exposure levels to oral reference
 doses).

 Lead-Related Risks

 As described in greater detail in a previous report (RCG/Hagler, Bailly, 1991, especially
 pp. 6-6 through 6-12) and as described in more detail in Appendix E, lead-related health
 risk reductions  are highly nonlinear with respect to .lead intake levels. Among the
 predominant interacting nonlinearities are the response relationships between blood leads
 levels and various adverse health endpoints (such as strokes), and the importance of
 baseline blood lead levels in determining where an individual is located along the
 functions relating blood lead to a health effect.

 To estimate how exposure to lead-impacted shrimp affect blood lead levels, four
 exposure groups were constructed to reflect the distribution of the consumption of rig-
 impacted shrimp (i.e., the majority of consumers who eat approximately the average
 amount of shrimp, versus the small percentile of individuals who consume relatively large
 quantities of shrimp).  These four exposure groups reflect different levels of impacted
 shrimp consumption, with the percentiles assigned to each group, and the amount of
 shrimp consumed by individuals in each group based on EPA's Tolerance Assessment
 System (TAS) data. This distribution is depicted in the top portion of Table 2-2.  The
 total quantities of rig-impacted shrimp implied by these quantities and percentile
 allocations is consistent in a mass balance perspective with the estimates of impacted
 shrimp harvested.

       Saltwater leach rate scenario.  For the pH-dependent leach scenario, because lead concentrations
       are much higher, the same level of health benefit derived below would be obtained at much
       lower human consumption rates for shrimp  (at 16.7% of rates shown above).

       From final Memorandum, from H. Jacobs to A. Tarnay, August 21,1992 (included below as
       Appendix F).             	^	             •
Subsequent to the completion of this exposure assessment and benefits analysis, EPA
undertook a review of the distribution of levels of shrimp consumption in the U.S. This
examination relied on USDA data from the National Food Consumption Survey,  1977-78
(Jacobs, 1992). The results, as presented in the bottom portion of Table 2-2 and in
Appendix F, are highly consistent with the exposure scenarios developed for the benefits
analysis.

For example, the lead-related benefits described in the subsequent chapter of this report
are derived from changes in lead intake for members of the highest two exposure groups
(reflecting the Q-MEI and MEI portions of the population).7  This TAS-based (and
mass balance consistent) benefits analysis assigns the 97th to 99.9th  percentiles of the

discernable incremental risks. Therefore, no estimable benefits are associated with reducing their lead

 shrimp eating public to the Q-MEI category (Exposure Group C), with shrimp intake
 estimated between 12 and 117 grams per day. In comparison, EPA's more recent
 investigation of USDA data shows shrimp consumption at 27 to 82 grams per day for the
 95th and 99th percentiles, respectively. While the percentiles do not match up in a
 manner that permits direct  comparisons of the shrimp consumption levels, it nonetheless
 is evident that, the two distributions are roughly equivalent.8

 Time and resource limitations precluded reanalyzing lead-related benefits based on the
 revised EPA shrimp consumption distribution. However, given the equivalence of the
 distributions, the benefit estimates derived below (on the basis of the mass balance TAS
 interpretation) would not be expected to change significantly if the new EPA
 consumption scenarios were used instead.


 2.23  The Number of Recreational Anglers Offshore in the Gulf

 As noted above, the average human exposure to rig-impacted finfish depends on how
 many people are exposed to the estimated mass of catch.   To derive this estimate,
 National Marine Fisheries Service (NMFS) data were used to derive the number of Gulf
 fishing participants, and then pro-rate according to the boat trips used to fish offshore as
 opposed to from beaches and piers.

 First, for the relevant states of AL, MS, LA, and TX, there are 5.78 million shore-based
 fishing days, and 6.38 million boat-based offshore angling days (NMFS, 1991). Thus,
 offshore angling represents 52.5% of Gulf-based recreational fishing.

 Second,  there are 984,000 total recreational Gulf anglers in LA, MS, and AL (three year
 average for 1987 -  1989).  There are no data for the number of Texas participants,  so
 these are assumed  to be proportional to the number  of fishing days originating in Texas
 as opposed to the other relevant states (54.9% of the angling).  Thus, assuming that
 Texas angling effort (days per angler) is the same as for the other states, a total estimate
    8 Under the pH-dependent leach scenario, the lead intake levels associated with the salt water leach
scenario benefits would be realized with shrimp consumption levels considerably less than (i.e., 16.7% of)
the levels noted in Table 2-2. For example, under the pH-dependent leach scenario, shrimp consumption
for the 97th and 99.9th percentiles would need to be only 2 to 20 grams per day, respectively, in order to
result in the lead exposures used to derive the lead-related health benefits developed in the analysis
described in Chapter 3. In contrast, the mean shrimp consumption level, based on 1977-78 USDA data, is
4.3 grams per day, and the 95th percentile is 26.7 grams per day. Thus, under the pH-dependent leach
scenario, shrimp consumption profiles would be well below the USDA data in order to derive the risk and
benefit levels developed below.  Alternatively, using the shrimp consumption distribution as shown in Table
2-2 in combination with the pH-dependent lead concentrations yields benefit levels considerably higher than
under the saltwater leach scenario (e-.g., compare the results in Tables 3-5 and 3-6).

 (i.e., including TX) of Gulf fishing participants of 2.18 million recreational angling
 participants is derived.

 Third, assuming that the number of participants in offshore angling is proportional to the
 number of trips taken offshore (52.5%) results in an estimate of 1.15 million persons who
 participate in boat-based offshore recreational fishing in the Gulf waters of TX, AL, MS,
 and LA. Given that recreational anglers may share their catch with family members, an
 estimate of roughly 1.7 million persons may be exposed to  recreationally-caught finfish
 from the Gulf (i.e., assuming half the anglers share their catch with a family member).

 Finally, because the selected regulatory option for drilling fluids and cuttings is zero
 discharge on platforms within! three miles from shore, it is relevant to determine the
 number of people exposed by way of Gulf offshore recreational angling within three
 miles of shore.  There are no data to accurately gauge the  number of participants who
 fish exclusively or predominantly in this range.  However, the level of exposure due to
 fish caught within three miles ;is  probably proportional to the weight-based share of fish
 landings taken within three miles.  NMFS data indicate that roughly half of the offshore
 recreational catch by weight is drawn from three miles or less from  shore (the weight-
 adjusted harvest from 1987 - 1989 is 53% within three miles).  Therefore, 53% of 1.7
 million yields roughly 900,000 persons as a measure of those who are predominantly
 exposed to offshore catch within three miles.9
 23    IMPACTED FISH HARVEST AND LEACH RATE SCENARIOS

 The human exposure levels are a function of: (1) the concentrations of pollutants in
 edible fish tissuej and (2) the quantity of shrimp and recreationally harvested finfish that
 are impacted by regulated platforms.  Data for these two factors were provided by
 Avanti (May 1992), and three scenarios are used to characterize each of these factors.

 First, to calculate tissue concentrations of metals for muds and cuttings, alternative leach
 rate scenarios were developed.  The results depicted in Section 3.0 reflect both saltwater-
 based and pH-dependent leach rate scenarios. The former implies highly-limited
 bioavailabiliry of lead and other metals, and the latter implies partial (e.g., 20%)
 bioavailability.

 For impacted finfish and shrimp harvests, three catch rate scenarios were developed
 (Avanti,  1992).  In the results that are presented in Sections 3.0, 4.0 and 5.0, the
 moderate scenario is depicted.  Sensitivity analyses are discussed to reveal the impact of
    9 The 900,000 estimate is applied to all regulatory scenarios, since this reflects the location of most of
the regulatory effort.  And, given the mass balance approach used, the carcinogenic risk results are
unaffected by the number of people exposed, so the 900,000 figure is convenient for all options.

3.0   DRILLING FLUIDS AND CUTTINGS

3.1   NONCARCINOGENIC RISKS

3.1.1  Risks Associated With Lead Intake

At proposal, a detailed analysis of lead intake by way of rig-impacted shrimp
(RCG/Hagler, Bailly, January 1991) indicted that appreciable benefits would be realized
due to control of drilling fluids and cuttings. Because an analysis of the benefits
associated with reduced exposure to lead is complex and highly nonlinear, time is not
available to conduct a detailed analysis of the lead-related benefits associated with the
revised regulatory package.  However, the prior lead benefits analysis can be used as a
benchmark against which benefits levels can be approximated.

Updating Lead Risk Reduction Values

The first step in this rough benchmark approximation is to update the original lead
benefits analysis to reflect subsequent insights gained by the Agency regarding the benefit
values associated with the monetized value of avoiding lead-related health effects.
These recent updates are reflected and described in the Regulatory Impact Analysis
developed for the drinking water standards for lead and copper (Wade Miller Associates
and Abt Associates, April 1991).      ,

The principal changes, relative to the original offshore effluent guidelines benefits
analysis (RCG/Hagler, Bailly, January 1991), increase the value of avoided stroke, heart
attack (CDH), and hypertension cases in adult white males. The new values are  $1
million per case,avoided for strokes and CDHs, and $628 for hypertension (whereas the
values previously applied were $52,200, $72,254, and $277, respectively).  Updated values
also were developed for IQ decrements in children, with the total predicted decrement in
IQ points valued at $4588 per point (whereas they previously had been valued at $471
per point of IQ decrement).1

An additional change involves extrapolating the lead-related health benefits  analysis that
pertain to white males aged 40 to 59 to include all males in this age group, not just
whites.  Precedent for such an expansion is found in the final RIA prepared for the
recent rulemaking on lead in drinking water (WMA and Abt Associates, April 1991).
    *  The net result of these changes, as applied to the original analysis conducted in 1991 (with a
baseline average daily lead intake of 0.057 /xg/day), increases the benefits of moving from baseline
conditions to zero discharge to $20.7 million to $72.4 million per year (from the previous estimate of $13.4
to $65.2 million per year).
RCG/Hagler, Bailly, Inc.

-------
                                        	3-2

According to the 1990 U.S. Consensus of Population, white males 40 to 59 are 77.5
percent of the U.S. population of all males aged 40 to 59. Thus, if the benefits due to
reduced CDH, stroke and mortality risks are applied to all adult males in that age
bracket, then the relevant monetized benefits for adult males increase by 29 percent (100
percent divided by 77.5 percent).2

Benchmarking Benefit Estimates

The benefits of reduced lead exposure due to the revised regulatory options have been
updated to account for changes from the regulatory options previously analyzed. The
analyses also embody enhanced modeling of pollutant uptake into fish tissue, and apply
more detailed shrimp and finfish harvest scenarios to ascertain the size of platform-
impacted  catch (these analysis are developed by Avanti Corp., May 1992).  As a
consequence,  the estimated levels  of lead intake have been revised for both baseline
conditions and for-the set of regulatory options currently under consideration.

Although many aspects of the underlying exposure analysis has changed, both the number
of people exposed and the distribution of relative lead intake  levels within the exposed
group are the same as previously analyzed (RCG/Hagler, Bailly, January 1991).
Therefore, although the benefits of changes in lead exposure  are nonlinear (particularly
through critical ranges of exposure), the analysis performed previously provides a set of
points oh this nonlinear function. These points link average lead intake levels to
monetized benefit levels for the relevant exposed group, accounting for the distribution
of intragroup exposure levels.  Accordingly, rough approximations of the benefits of the
present set of regulatory options can be ascertained through benchmarking along the
previously derived benefits function. This is accomplished by linearizing segments of the
function (interpolating between points according to average lead intake levels).

Table 3-1 indicates, for relevant average lead (pb) intake levels, the geometric mean
blood lead levels (GMPbB), and the percent of the exposed population with blood lead
above the 10 micrograms per deciliter benchmark for adults and children.  These results
are extracted directly from RCG/Hagler, Bailly (1991).
    2 As described in greater detail in Appendix E, hypertension and related risks due to elevated blood
lead levels in adult males are estimated using a univariate logistic function (Equation 1 in Appendix E)
derived by EPA's Office of Air Quality Planning and Standards (OAQPS). This is based on the Agency's
multiple logistic regression model as used to estimate elevated risks for the lead in gasoline and lead in
drinking water. Use of the OAQPS logistic function may introduce error into the estimation process
because it relies on means, drawn from the NHANES II sample, in its non-linear equation. Nonetheless,
use of the OAQPS approach is believed to provide a reasonable approximation of the effect of blood lead
on blood pressure (US EPA, 1992a).

 Results — Saltwater Leach Scenario

 Table 3-2 summarizes the average lead intake levels for the four relevant regulatory
 options, under the saltwater leach scenario.  These reflect lead exposure by way of
 platform-impacted shrimp.3  At baseline, average lead intake amounts to 0.058 us/day
 which coincides with one of the levels analyzed in RCG/Hagler, Bailly (1991), as shown
 in Table 3-1.  At the regulatory option of zero discharge (barge) within three'miles and
 BAT (1:3) beyond, average lead intake drops to  0.021 fig/day, considerably less than the
 0.035 level for which benefits were estimated in RCG/Hagler, Bailly (1991). Therefore
 the benefits of moving from baseline (0.058 pg pb/day) to zero discharge within three  '
 miles and  BAT beyond (0.021 ^ pb/day) are approximated here by (and, in reality are
 somewhat greater than) the benefits previously estimated for moving from 0.057 to 0.035
 fig pb/day. Likewise, the benefits of moving from baseline (0.058 jig/day) to zero
 discharge are equivalent to the previously estimated benefits of moving from 0 057 we/day
 to zero intake.                                                                    &   3
      Lead exposures by way of recreationalfy harvested finfish are too low to estimate changes in blood
lead distributions (e.g., 0.00064 ug/day for average exposed individual at baseline — see Appendix B —
which is roughly one percent of the comparable shrimp-related average exposure)

Building upon RCG/Hagler, Bailly (1991) in this fashion, the lead intake levels for the
present set of regulatory options can be associated with estimates of the expected
reduction in selected adverse health effects.4  The incremental lead-related health risk
reductions for all three relevant regulatory options are shown in Table 3-3 (for the
saltwater leach scenario) and the monetized value of these benefits for the selected
option (3  Mile Gulf/CaUfornia) are shown in Table 3-4.  The dollar values per case
    4  The risk reduction benefits (number of cases avoided) are based on applying the appropriate dose-
response factors to the relevant subgroups of the exposed populations, with the population subgroup sizes
determined by national demographic data. For example, most of the monetized benefits arise from
reduced risks to adult males in the 40 to 59 age bracket According to the 1990 U.S. Census, this group of
individuals (males 40 to 59) comprises 11.6% of the total U.S. population. Therefore, they are estimated to
represent 11.6% of the 50 million individuals who are shrimp consumers; that is, the benefits estimates
pertaining to adult males are based on an exposed population of 5.8 million adult males in the relevant age
bracket (50 million times 11.6%).  These exposed individuals are then allocated to each of the four shrimp
consumption exposure groups (e.g., 0.1% of 5.8 million, or 5,800 individual males between 40 and 59 years
of age, are in the highest exposure group; 2.7%, or roughly 160,000 such males, are allocated to the second
highest exposure group, etc.).
       The estimated numbers of exposed pregnant women (newborn infants) and children (age 5 cohort)
are derived in comparable fashion. These calculations yield the following results: for the age 5 cohort,
645,000 individuals are in the low exposure group, 82,500 are in the moderate exposure group, 21,750 are
in the moderately high exposure group, and 750 are in the highest group. For pregnant women (newborn
infants), 722^17 are in the low exposure group, 92,415 are in the moderate exposure group, 24,364 are in
the moderately high exposure group, and 840 are in the highest group.

 The dollar value of lead-related benefits for all regulatory options is shown in Table 3-5,
 with most of the benefits accruing at the 3 Mile Gulf/California option ($28.0 to $103.3
 million per year). Benefits at zero discharge amount to between $29.9 to $110.1 million
 per year.

 Results — pH-Dependent Leach Scenario

 Under the "saltwater" leach scenario, which implies a low level of lead bioavailability, the
 benefits of the selected option amount to up to $103 million per year, as depicted in
 Table 3-5.  Alternatively, if the lead is bioavailable to a greater, but still limited degree
 (e.g., 20%), as implied by the  pH-dependent leach scenario, then the resulting benefits
 increase substantially — up to a $650 million per year, as depicted in Table 3-6. While
 the benefit levels are appreciable under either leach rate scenario, the sensitivity of the
 results to the leach factor indicates the importance of additional research in this area.5

3.1.2  Other Noncarcinogenic Risks
Aside from lead, other compounds pose noncarcinogenic risks via drilling fluids and
cuttings. As summarized in Table 3-7, shrimp-related intake of several toxic compounds
occur at levels of concern relative to established oral reference  doses (RfDs).6  In
particular, under the saltwater leach scenario, mercury intake under baseline conditions
amounts to 0.3% of the oral RfD for an average individual, 40% of the RfD for the
quasi-MEI, and is more than two and a half times the RfD for an MEL  Arsenic,
Cadmium and Chromium VI exposures also are at levels of concern for individuals with
higher than average exposure to impacted shrimp.7  All of the regulatory options beyond
baseline reduce average  exposures to below 0.1%  of the respective oral RfDs,  and also
reduce exposures for Q-MEIs and MEIs.8
3.2    CARCINOGENIC RISKS

Carcinogenic risks posed by way of muds and cuttings are associated with exposure to
arsenic by way of shrimp consumption.  Comparing Table 3-8 to Table 3-9, it is evident
that these risk reductions are highly dependent on the leach rate scenario applied. The
cancer risk reduction benefits of moving from baseline to zero discharge ranges from up
to $448,000 under the saltwater leach rate scenario, but are more than $3.1 million per
year under the pH-dependent leach scenario.9-10
    6 Oral reference doses are threshold-like levels below which ingestion-related chromic exposures are
not believed to pose appreciable human health risks.

    7 Under a pH-dependent leach scenario, the exposure levels are even greater. For example, baseline ,
mercury intake for the average exposed individual is 1.0% of the oral RfD (rather than the 0.3% shown in
Table 3-7). Also note that the reported values are for shrimp only - exposure levels by way of finfish
impacted by muds and cuttings are below 0.1% of the oral RfDs.

    8 Note that the Q-MEI and MEI exposure levels are insensitive to regulatory scenarios beyond BAT
for all platforms (other than zero discharge for all platforms, under which exposures are zero) because
these exposures are defined by shrimp caught from those platforms with nonzero (Le., BAT-level)
discharge. In reality, those options that extend zero discharge to greater numbers of platforms will reduce
exposures for those individuals with above average exposure scenarios.

    9 These benefits are for shrimp consumption only. Finfish-related risks posed by muds and cuttings
are considerably lower, with individual risk levels roughly one percent of those due to shrimp, and only two
percent as many individuals exposed (Le., benefits would amount to less than $100 per year under the
saltwater leach scenario).

    10  The Agency is considering new evidence of the carcinogenic potency (and target organs) of arsenic,
and the estimated cancer risks associated with these exposure levels may increase appreciably if EPA
updates the carcinogenic slope factor for arsenic as anticipated (Dr. Charles Abernathy, U.S. EPA,
personal communication, October 1992).

 4.0   PRODUCED WATER — EXISTING PLATFORMS

 4.1   NONCARCINOGENIC RISKS

 Levels of human exposure for noncarcinogens were estimated for sixteen relevant
 contaminants with Agency-derived oral exposure reference doses (oral RfD, as reported
 previously, in Table 2-1).  Exposure levels (human intake) were estimated for average,
 quasi-MEI, and most exposed individual (MEI)  scenarios for recreational finfish
 consumption.1 These exposure levels were then compared to the oral RfDs (adjusted to
 reflect the intake level, in jig/day for a 70 kg adult, that is equivalent to the oral RfD).

 Human exposure to the noncarcinogens analyzed occurs  at very low levels relative to the
 oral RfDs with only 2.4 Dimethylphenol exposure occurring at or above 0.1% of the oral
 RfD.  As indicated  in Table 4-1, the most significant exposure at baseline is an MEI
 intake level for finfish that is 6.5% of the RfD.

 Lead exposures also are reduced through the  impact of the produced water regulatory
 options on lead concentrations in recreationally  harvested finfish impacted by offshore  oil
 and gas operations  in the Gulf. As shown in Table 4-2, the associated benefits amount to
 $114,000 per year at zero discharge.


 4.2    CARCINOGENIC RISKS

 Carcinogenic risks for finfish were estimated for arsenic, benzene, and benzo(a)pyrene.
 As shown in Table 4-3, a reduction of 0.006 excess cancer cases per year is estimated at
 zero discharge.  This translates to an annual monetary value of $11.800 to  $59.700 (1991
 dollars).  Additional benefits may be anticipated to the extent that the regulations induce
 any incidental reductions in radium exposure.


 43    TOTAL BENEFITS

 Combining the cancer benefits with the lead-related benefits described above, the annual
 monetized benefits of regulating produced water at existing platforms amount to as much
 as $164,000 per year.

This total is not inclusive of incidental radium-related health benefits or other, non-
health, benefits which  may result from these regulations.
    1  Human exposure by way of shrimp and commercial finfish consumption could not be estimated for the
produced water wastestream.

 5.0   PRODUCED WATER —NEW SOURCES (NSPS)

 5.1    NONCARCINOGENIC RISKS

 As noted for existing platforms, levels of human exposure for noncarcinogens as
 compared to Agency-derived oral exposure reference doses (oral RfDs) were insignificant
 except for 2,4-Dimethylphenol and lead.

 Table 5-1 presents exposure results for the former, indicating a baseline average
 exposure via recreationally caught finfish of 0.3% of the oral RfD.  This average
 exposure declines to 0.2% for application of improved gas flotation at all  platforms, and
 drops to roughly 0.1% of the RfD when zero discharge is applied to platforms within   -
 three or four miles of shore.

 Lead exposure-related benefits are shown in Table 5-2. The lead-associated benefits
 amount to $145,000 per year at zero discharge.

 6.0   CONCLUSIONS

 The incremental monetized benefits estimated above are for quantified health risk
 reductions attributable to regulating drilling fluids and cuttings, and produced water at
 offshore oil and gas platforms.             -

 The principal monetized findings are:

       *•      F°r muds and cuttings, the incremental benefit of moving from baseline
              controls to the selected option of zero discharge within three miles and
              BAT beyond (3 Mile Gulf/California) amount to between $28 and $104
              million per year; and between $30 to Sill million annually for zero
              discharge for all platforms (1991 dollars;  saltwater leach scenario).  These
              benefits may amount to as much as $696 million per year under an
              alternative, pH-dependent leach rate scenario.

       *•      For produced water controls at existing sourcesT incremental benefits
              amount to nearly $164.000 per year (1991 dollars) due to cancer risk
              reductions and lead-related health benefits at zero discharge. Incidental
              radium-related risk reduction benefits are not included in these estimates.

       *•      For produced water control  at new sources, incremental benefits of up to
              $225,000 per year (1991 dollars)  accrue due to cancer risk reductions and
             lead-related health benefits at zero discharge.  Incidental radium-related
             risk reduction benefits are not included in these estimates.

While these monetized benefits of the offshore oil and gas effluent guidelines appear to
significant, it is important to recognize that virtually all of these benefits arise from
estimated reductions in a limited range of adverse health effects associated with lead
exposure. The estimated monetized benefits for both the muds and cuttings  and
produced water wastestreams are appreciably limited by the omission of several
potentially significant types of benefits that could not be monetized due to current
limitations of the  data and quantitative methods. Table 6-1 provides an overview of the
types of benefits that were monetized as well as those potential benefits that could not be
assessed reliably in quantitative and/or monetary terms. This indicates the extent to which
many potentially significant benefits are excluded from the monetary benefits assessment.

A PROBABILISTIC ASSESSMENT OF HEALTH BENEFITS
         FROM REDUCED LEAD LEVELS

-------

-------
                                                                                 E-l
 E.1   INTRODUCTION
 The benefits analysis estimates health benefits  to  adult males based on dose-response
 functions for four health endpoints: death, hypertension, coronary heart disease (CHD), and
 stroke.   For each of these endpoints, changes  in  mean blood lead levels (PbB) were
 associated with an incidence of occurrence.

 One approach to estimating changes in blood lead levels is to assume the baseline levels are
 equal across all individuals.  This approach, however, can both understate and overstate
 health benefits  because all individuals within a population do not  exhibit  mean PbB
 concentrations.  Rather, population-wide  responses  can be represented better by using a
 statistical distribution of PbB as the baseline, and then shifting this distribution according to
 the estimated pattern and levels of exposure.


 E.2   METHODS

 Benefits to adult males were estimated based on the expected number of cases for each
 regulatory scenario for each of the four health endpoints, assuming the population sizes used
 in the current benefits analysis.

 For each health endpoint, probabilistic  responses  were estimated using the following
 approach, and as depicted in Figure E-l:

       (1)   Generate samples from lognonnal distributions of blood lead before and after
             regulatory  control using Latin-Hypercube analysis.

       (2)   Generate frequency distribution of health response before and after regulatory
             control based on dose-response functions.

       (3)   Calculate expected number  of responses (i.e., cases of lead-related effects)
             before and after control.

       (4)   Calculate incremental number of cases (i.e., benefits) as difference in expected
             number of  cases before and  after regulation.

 The following dose-response relationships were used for the four health endpoints (EPA,
 1989d):
 Hypertension:

       Ap = [1 + e -Q-7*30n PbBl) - 2.7441-1 _ M + g -0.793(ln PbB2) - 2.7441-1                 (j-v


 where Ap is the change in probability of hypertension in moving from blood levels 1 and 2.

 Dose-response relationships for coronary heart disease (CHD), strokes, and death are all
 based on changes in blood pressure (BP) over a ten-year period:
       ABP = 4.609 (hi PbBx - In PbB2)
                                                                                (2)
The annual number of cases of each health effect is then calculated by multiplying the
incremental probability (Ap) by the exposed population and dividing by ten. Ap is defined as:
Coronary Heart Disease:

           = [1 + e -0-030365(DBP1) + 4.9961-1 . M  + e -0-<>30365(DBP2) + 4.9961-1
                                                                                (3)

where DBP1 and DBP2 are the mean diastolic blood pressure before and after regulatory
control.
Death:
          = [1 4- e -0-03516(DBP1) + 5.31581-1 _ M + & -0.03516(DBP2) + 5.31581-1
                                                                                (4)
Stroke:
           = [1 + e -0-04066(DBP1) + 8,588891-1 . M + g -0.04066(DBP2) + 8.588891-1
                                                                                (5)-
For each of three endpoints, above, the baseline diastolic blood pressure before regulatory
control (DBPj) was assumed to be 84.75 mm Hg (EPA,  1989d).

    The USDA Fish Species Code List (Attachment B) was used to identify shellfish foods
and shrimp foods for this analysis.  Shellfish are identified by an "S" in the type variable and
shrimp are identified by the word "shrimp" anywhere in the food variable.  For foods
containing both fish and other foods (i.e., food codes with fish but with the first 2 digits not
equal to 26) the amount of fish consumed was calculated as 1/2 the total weight.

   The tables of shellfish and shrimp consumption rates contain survey-weighted means and
percentiles of three-day consumption.  The first column gives estimates for the total
population. The second column contains estimates for  the population who consume shellfish
or shrimp, respectively. These estimates were prepared by taking means and percentiles over
the upper x% of the total population, where x% of the total population consume the food
type in the long term.  The Marine Fisheries Service/National Purchase Diaries Research
Inc.  (NPD) survey of 1973-74 which is based on 30 days of consumption is a better estimate
of the percent of the population who consumes shellfish or shrimp than the USDA survey
which is based on only 3 days of consumption.  On the basis of the data from the NPD
survey 32% of the population consumed shellfish sometime during the 30-day monitoring
period of the study and 22% consumed shrimp during the 30-day period.  Accordingly, the
values in the second column are based on the upper 32% and 22% of the corresponding
three-day consumption values in the USDA data set. This subset contains all of the
respondents who consumed shellfish or shrimp during the three-day survey plus an
appropriate number who did not consume fish but who would be assumed to consume fish
over a longer period.  See Attachment C for more details on the statistical procedures.

    If you have any questions or need additional information, please let me know.

USDA1977-78 NATIONAL FOOD CONSUMPTION SURVEY

Description
    The USDA conducts me National Food Consumption Survey (NFCS) approxima»ely
every 10 years. The most recent MFCS survey for which data are currently available is the
NFCS 1977-1978 survey suite. This suite is comprised of the Basic survey, which was a
multi-stage, stratified probability sample of all households in the continental United
States,  which is itself comprised  of 4 quarterly surveys, plus several supplemental
surveys covering Alaska, Hawaii, Puerto Rico, households containing one or more
elderly persons (Elderly), and households eligible for die Food Stamp Program (Low-
Income). Survey data were collected both for households and individuals, the individual
consumption surveys were found to be the most appropriate for this analysis, as they
reflect food consumption  both at home and away from home,  and reflect direct
consumption by the individual.

Sampling
    The Basic survey was conducted from April 1977 - March 197.8, and consists of
information on 30.770 individuals over the four quarterly surveys. The Alaska and
Hawaii surveys were conducted in  January, February, and March 1978, and consist of
information on 3.086 and 2,393 individuals, respectively. According to USDA, the
response rates on these surveys were approximately 70%. The individual surveys consist
of 1-day recall and 2-day record keeping reports of all food consumed, for a total of 3
days of food monitoring. Foods are cte««fM** according to an extensive food code list
and amounts consumed are calculated from the mimber of servings and tabulated serving
sizes.

Data processing
    From the USDA food code list, food codes representing all foods either whole or
partially fish  were extracted. Fish food codes were  assigned as freshwater (F).
estuarine (E). marine (M), or unknown/nnclassiriable (U). as shown in the attached list.
Some fish codes were assigned more than one type (BF.MF) because they are found in .
several environments. Food codes containing shellfish are marked with an *.
    In order to assign the food codes of type U appropriately, the average amounts of
food consumed person per day for each of the F, E, and M types were computed. No
foods of type U contain shellfish,  so only non-shellfish foods were included in these
calculations. The non-U non-shellfish consumptions were round to be in the ratio of 14%
F, 21% E, and 65% M. This ratio was applied to the food codes of type U to divide the
amount consumed in each meal into the estimated contribution to freshwater, estuarine,
and marine consumption. In  all calculations, for foods containing both fish and other
foods (Le. food codes with fish but with a first 2 digits not equal to 26) dse amount of fish
consumed was calculated as  1/2 the total food weight.  For food codes with multiple
types , the amount of fish consumed was divided equally between die two types. 3-day
average consumption rates of fresh-water, estuarine, marine, and total  fish consumption

-------
  with and without shellfish were computed for each person as the totil fish consumption
  of the coRSSpoading type divided by 3 days.

      Individual survey weights as related on the survey tapes were used in oar analysis.
 These were calculated by USDA to improve the correspondence of the survey wish the
 reference population on demographic factors, and their use is  appropriate in our
 application. The total weights of for the spring survey were found to be approximately
 2/10 that of the other 3 seasons. This was checked with USDA and confirmed to be doe
 to an error in formatting the spring tape, so the sample weights for spang were multiplied
 by 10 to make them comparable with the other 3 seasonal surveys. Tfee totti survey
 weights for the Alaska and Hawaii surveys were computed and compared wim the total
 weights in the Basic survey. Adjustment factors were applied to the Alaska and Hawaii
 weights so that the total adjusted sample weight for each state was propomosaie to the
 ratio of she state population to  the total population of the continental United  States
 represented by the Basic sample.

     Weighted univariate statistics were calculated on the total and feesh-water/esmasine
 fish consumptions as described in the next section.

 Shortcomings

     These data were  collected in 1977-1978, and fish consumption patterns may well
 have changed since mat time.

     The very short monitoring period is of concern. Thfee-day avenges are likely to
 contain a substantial effect of day-to-day variability in fish consumption. Though the
 mean of 3-day averages over the population will be the same as for long-term averages,
 the upper percentiles of the distribution of  3-day averages will be higher, possibly
 substantially higher, man those of long-term eftn^mpriftfi rates.

    The Alaska and Hawaii samples were obtained only during one quarter of the year,
 and may be somewhat non-representative of me distribution of fish consumption over the
 entire year for those states, particularly for Alaska. However, these states represent such a
 small fraction of the U.S. population that any such effect can be assumed to be small, but
 it should be noted.

Advantages

    This is a large and well-designed sample,  and results from it appear to be generally
applicable to ifac question at

                    STATISTICAL PROCEDURES FOR
                 ESTIMATING MEANS AND PERCENTILES
     We estimated the mean and upper percentiles  of  the
freshwater, estuarine and marine  fish consumption rates  using
USDA survey weights.  The mean consumption  rates  are calculated
as follows: if the consumption rates  (freshwater,  estuarine and
marine) for each of the n respondents are c,, c,,  ..., cn and the
corresponding survey weights are  w1f w2,  .. .wn, then  the  weighted
mean consumption is computed as
     If all the weights
unweighted mean.
                         w{ are equal this reduces to the usual
   n
     Upper percentiles (90th,  95th,  and 99th)  of the distribution
of three 3 -day average consumption rates were estimated in the
following way:  let the ordered consumption values be
< c
 w
   ,,.
      (n).
          <. v.< c
           Then
o  ** c(J) where j satisfies
                  _. and the corresponding weights be w(1), w(?),
                  e estimate  of the p-th quanjtile was computed as
      -
     £ w
     1=1
                    and
      -1        -1

for p -  .90,  .95
                   .99.
     This estimate corresponds to that obtained from the weighted
cumulative sample distribution.
