                                     SECTION 1: INTRODUCTION

        This analysis is submitted in  support of the final effluent limitations guidelines and standards for the
Pesticide Chemical Manufacturers Industry. The report analyzes the cost-effectiveness of the final rule.1  The total
annualized cost incurred under the rule is compared to the effectiveness of the rule in reducing the discharge of
pollutants. The effectiveness measure used is pounds of pollutant removed weighted by an estimate of the relative
toxicity of the pollutant.  The rationale for this measure,  referred  to as "pounds-equivalent (PE) removed,"  is
described later in this report.

        Section 2 of the report discusses the cost-effectiveness methodology employed including the pollutants
included in the analysis and the toxic weighting factors.  Section 3  reviews the changes in the cost-effectiveness
analysis that have occurred since issuance of the proposed rule.  Section 4 presents the results of the final analysis.
In Section 5, the final cost-effectiveness values are compared to cost-effectiveness values for other promulgated
rules.  Seven appendices are also included. Appendix A lists the pesticide active ingredients (PAIs) or classes of
PAIs considered for regulation.  Appendix B lists the individual PAIs being regulated. Appendix C lists the PAIs
or classes of PAIs and priority pollutants included in the cost-effectiveness  analysis.  Appendix D provides toxic
weighting factors for PAIs and priority  pollutants. Appendix E lists the removal efficiencies for priority pollutants
at publicly-owned treatment works (POTWs).  Appendix F provides details regarding pesticide manufacturing
facilities that are excluded from the cost-effectiveness analysis. Finally, Appendix G provides a sensitivity analysis
of POTW removal efficiencies.

 Pretreatment Technology, And New Source Performance Technology for the Pesticide Chemical Industry (hereafter
 the Technical Development Document).

                                     SECTION 2: METHODOLOGY

         Cost-effectiveness calculations are used in the process of setting effluent limitations guidelines and standards
to rank the efficiency of regulatory options in removing pollutants. Cost-effectiveness analysis also facilitates the
comparison of the efficiency of proposed or promulgated rules to the efficiency of previous rules. Cost-effectiveness
is defined as the incremental (to another option or to a benchmark, such as existing treatment) annual cost of a
pollution control option in an industry or industry subcategory per incremental pollutant removal (measured in
copper-based pounds-equivalent).  In other words, the cost-effectiveness value represents the unit cost of removing
the next pound-equivalent of a pollutant.  While not required by the Clean Water Act, the cost-effectiveness analysis
is a useful tool for evaluating regulatory  options for the removal of toxic pollutants.2  It is not intended to analyze
the removal of conventional pollutants (oil and grease, biological oxygen demand and total suspended solids), thus
the removal of conventional pollutants is not addressed in this report.

         A cost-effectiveness calculation  is simply a ratio of the annualized cost of a regulatory control option for
a group of dischargers to the pollutant loadings removed from surface waters by that option for that particular group
of dischargers.3 Three factors are of particular importance in the cost-effectiveness calculations. First, the analysis
is based on removals  of "pounds-equivalent" - a term used to describe a pound of pollutant weighted for  its
toxicity.4 Use of pounds-equivalent reflects  the fact  that some pollutants are more toxic than others and permits
removals to be summed across pollutants. Second, where there are a number of control options being evaluated,
the analysis is done on  an incremental  basis — using the incremental cost and removals of one control option
compared to another control option or to existing treatment.5  Third, cost-effectiveness values are considered high
or low only within a given context, such as similar discharge status or compared to effluent limitations guidelines
for other industries.
    2Cost-effectiveness analysis is applied to Best Available Technology Economically Achievable and Pretreatment
Standard for Existing Sources rules which control toxic pollutants.
    3For control technologies that remove pollutants that would otherwise be volatilized prior to dilution in the
receiving stream, the cost-effectiveness analysis includes removals of volatile pollutants as well as removals from
the aqueous wastestream.
    4Copper is used as the standard pollutant for developing toxic weighting factors because it is a toxic metal and
is commonly both released and removed from industrial effluent.
    ^Incremental cost-effectiveness can be calculated from current treatment or from another control option.
                                                    2.1

-------
        There are a number of steps in a cost-effectiveness analysis which may be summarized as follows:

                Determine the relevant wastewater pollutants;
                Estimate relative toxic weights of priority and other pollutants;
                Define pollution control approaches;
                Calculate pollutant removals for each control option;
                Determine annualized cost for each control option;
                Calculate cost-effectiveness values (and adjust to 1981 year dollars); and
                Compare cost-effectiveness values.

These steps are discussed below.

1.      Pollutant Discharges Considered in a Cost-Effectiveness Analysis

        Under the pesticide manufacturer effluent limitations guidelines, 260 pesticide active ingredients (PAIs) or
classes of PAIs were considered for regulation.  Some of the factors considered in selecting pollutants for regulation
include toxicity, treatability, measurability,  frequency of occurrence, and amount of pollutant in the wastestream.
Of the 260 PAIs or classes of PAIs, 120 individual PAIs were selected for regulation. In addition, 28 priority
pollutants were identified for regulation. Not all regulated pollutants, however, are included in the cost-effectiveness
analysis since some regulated pollutants may no longer be produced and therefore have no associated compliance
costs.  Also, measurements of pollutants loadings are not available for some regulated pollutants. There are 75
PAIs or classes of PAIs and  46 priority pollutants included in this cost-effectiveness analysis.6  Appendix A lists
the 260 PAIs or classes of PAIs considered for regulation. Appendix B lists the 120 individual PAIs and 28 priority
pollutants selected  for regulation.  Appendix C  lists the 75 PAIs or classes  of PAIs and 46 priority pollutants
included in the cost-effectiveness analysis.

2.      Relative Toxic Weights of Priority and Other Pollutants

        Cost-effectiveness analyses account for differences in toxicity among the regulated pollutants by using toxic
weighting  factors (TWFs). These factors are necessary because different pollutants have different potential effects
on human  and aquatic life. For example, a pound of nickel (TWF=0.036) in an effluent stream has a significantly
lesser potential effect than a pound of cadmium (TWF=5.12).   The toxic weighting factors are used to calculate
the (copper-based) "pound-equivalent" unit —  a standard measure of toxicity.
     *The number of priority pollutants included in the analysis is greater than those regulated because some non-
 regulated priority pollutants that are present at low levels hi the manufacturing processes are controlled to some
 extent as a result of the technologies used to control for regulated PAIs or priority pollutants. Also, the 75 PAIs
 or classes of PAIs incorporated hi the analysis include nine PAIs that are not part of the 120 regulated PAIs because
 these rune PAIs are associated with regulated priority pollutants hi the wastestream.
                                                    2.2

-------
        In the majority of cases, toxic weighting factors are derived from both chronic freshwater aquatic criteria
(or toxic effect levels) and human health criteria (or toxic effect levels) established for the consumption of fish.7
These factors are then  standardized by relating them to copper.8  The resulting toxic weighting factors for each
PAI and priority pollutant are shown in Appendix D.  Some examples of the effects of different aquatic and human
health criteria on weighting factors are shown in Table 1.

        liter of water.
*  Based on ingestion of 6.5 grams of fish per day.
** While the water quality criterion for copper has been revised (to 12.0 ug/1), the cost-effectiveness analysis uses
the old criterion (5.6 ug/1) to facilitate comparisons with cost-effectiveness values for other effluent  limitations
guidelines.  The revised higher criteria for copper results in a toxic weighting factor for copper not equal to 1.0
but equal to 0.467.


        As indicated in Table 1, the toxic weighting factor is the sum of two criteria-weighted ratios: the "old"
copper criterion divided by the human health criterion for the particular pollutant and the "old" copper criterion
divided by the aquatic chronic criterion. For example, using the values reported in Table 1, 10.96 pounds of copper

Factors for Pesticide Active Ingredients and Priority Pollutants, Final Report, July  13,  1993, located hi the
Administrative Record.

the old criterion (5.6 ug/1) to facilitate comparisons with cost-effectiveness values for other effluent limitations
guidelines.  The revised higher criteria for copper results in a toxic weighting factor for copper not equal to 1.0

pose the same toxicity in surface waters as one pound of cadmium since cadmium has a toxic weight 10.96 times
(5.12/0.467=10.96) as large as the toxic weight of copper.  The cost-effectiveness analysis examines only the
toxicity of pollutants, and is not a full risk-based analysis that would consider pollutant fate, transport and exposure
pathways.

3.      Pollution Control Options

        Limitations under the final rule are based on the use of biological treatment, hydrolysis, activated carbon,
chemical oxidation, resin adsorption, solvent extraction, incineration and/or recycle/reuse to control the discharge
of PAIs in wastewater.  Further information on the control options can be found in the Technical Development
Document.  The cost-effectiveness analysis was conducted separately for direct and indirect dischargers.  Costs for
direct dischargers were calculated for compliance with a  Best Available Technology (BAT) regulation; costs for
indirect dischargers were calculated for compliance with Pretreatment Standard for Existing Sources (PSES).9  Each
discharge category was further  divided into  two subcategories:   organic pesticide chemicals manufacturing
(Subcategory A) and metallo-organic pesticide chemicals manufacturing (Subcategory B).  No new limitations are
being promulgated for Subcategory B.'°

4.      Calculation of Pollutant Removals

        The reductions in pollutant loading to the  receiving water body have been calculated for the final rule.
These at-stream pollutant removals are equal to end-of-pipe pollutant removals for direct dischargers. For indirect
dischargers, however, at-stream and end-of-pipe removals may differ due to treatment at the POTW.  Calculation
of removals for direct and indirect dischargers is discussed  below.

        Direct dischargers

        Current  and post-treatment end-of-pipe annual pollutant loadings for each facility have been estimated.
Removals are calculated as  the difference between current and post-treatment  discharges.   Removals are then
weighted using the copper-based  toxic weighting factors  and reported in  pounds-equivalent.   Total removals
associated with Subcategory A are calculated by summing removals over all direct discharging facilities.  There are
     9A discussion of the economic impacts of the regulation can be found in Economic Impact Analysis of Final
 Effluent Limitations Guidelines and Standards for the Pesticide Manufacturing Industry (hereafter the Final EIA).
     10For  an analysis  of the cost-effectiveness of  regulations upon Subcategory  B chemicals,  see  the cost-
 effectiveness analysis presented at proposal.
                                                    2.4

-------
no removals  for Subcategory  B since direct discharge of such chemicals is already limited to zero by BPT
regulations.

        Indirect Dischargers

        Calculation of pollutant removals for indirect dischargers is similar to calculation of removals for direct
dischargers.  However, calculation of priority pollutant removals includes the possible effects of treatment at the
POTW.  For some pollutants, part of the end-of-pipe pollutant loadings for indirect dischargers may be removed
by the POTW. Therefore, at-stream loadings from an  indirect discharging facility may be less than end-of-pipe
loadings.  As a result, the at-stream removal of pollutants attributable to PSES regulations are considered to be less
than end-of-pipe removal of pollutants.  The cost-effectiveness analysis takes into account POTW removals for
priority pollutants and attributes to the regulation only removals that occur at-stream."

        For example, if a facility is discharging 100 pounds of cadmium in its effluent stream to a POTW and the
POTW has a removal efficiency for cadmium of 38 percent, then the amount of cadmium discharged to surface
waters is only 62 pounds. If the regulation results in an end-of-pipe reduction of cadmium in the effluent stream
to SO pounds, then the amount discharged to surface waters is calculated  as 50 pounds multiplied by the POTW
removal efficiency factor (1-.38 or .62), i.e., 31 pounds (50 pounds  x .62). Cost-effectiveness calculations reflect
the fact that the actual reduction of pollutant discharge to surface waters is not 50 pounds (the change in the amount
discharged to the POTW), but 31 pounds  (= 62 - 31)  (the change in the amount actually discharged to  surface
waters).  The analysis does not consider any pollutants that remain in the waste sludge of the POTW. The POTW
removals factors used in the analysis are shown in Appendix E.

5.      Annualized Costs for the Final Rule

        Full details of the methods by which the costs of complying with the final rule were estimated can be found
in Chapter 8, Engineering Costs and Non-Water Quality Aspects, of the Technical Development Document.  A brief
summary of the compliance costs is provided below.

        Three categories of compliance costs associated with pesticide manufacturing were evaluated:  capital costs,
land costs, and operating and maintenance costs (including sludge disposal and self-monitoring costs).  While the
capital and land costs are one-time "lump sum" costs,  the operating and  maintenance costs are evaluated on an
    "POTW removals for PAIs are not accounted for in the main analysis due to the lack of definitive treatment
data.  Appendix G, however, provides a sensitivity analysis of POTW removal efficiencies for PAIs.
                                                   2.5

-------
annual basis.  The capital and land are conservatively assumed to have a productive life of ten years.  Using the
weighted average cost of capital, the capital and land costs are amortized to account for the cost of financing the
investment (through equity and debt) over the ten-year period.12  Total annualized costs are equal to annualized
capital  and  land  costs  plus operating  and maintenance costs.    For  facilities  that  both manufacture and
formulate/package pesticides, the compliance costs apply only to the manufacturing operations of the facility.  All
of the compliance cost estimates are based on the assumption that, whenever possible, facilities will build on existing
treatment.  The reported costs are the full costs of compliance, some of which will be borne by the government in
the form of decreased tax receipts.  The analysis therefore overstates the burden of the regulations on industry.

6.      Calculation of Cost-Effectiveness Values

        Facilities are included in the analysis only if they have pollutant removal values associated with compliance
costs. As a result, under the final  rule, certain facilities with compliance costs  are not included  in the cost-
effectiveness analysis. (See Appendix F for details of excluded facilities).

        Cost-effectiveness values are calculated separately for direct and indirect dischargers for Subcategory A.
For any given subset of dischargers and subcategories subject to proposed regulatory controls, the cost-effectiveness
value for the rule is calculated as the ratio of incremental  annual cost of the rule to the incremental pounds-
equivalent removed by the rule.   The incremental effectiveness may be viewed both in comparison to the baseline
scenario and to another regulatory option.  Cost-effectiveness values are reported in units of dollars per pound-
equivalent of pollutant removed.  For the purpose of comparing cost-effectiveness values of the final rule to those
of other promulgated rules, compliance costs used in the cost-effectiveness analysis are adjusted to 1981 dollars
using Engineering News Record's Construction Cost Index (CCI).  This adjustment factor is calculated as follows:

   Adjustment  factor =   1981 CCI       =      3535     =       0.823
                         1986 CCI               4295
    12For details on the weighted average cost of capital see the discussion of the facility closure analysis in the final
EIA.
                                                    2.6

-------
        The equation used to calculate cost-effectiveness is:

        CEk    =        ATCk -ATCkl
where:
        CEk    =      cost-effectiveness of Option k ;
        ATCk  =      total annualized treatment cost under Option k ; and
                =      pounds-equivalent removed by Option k .
The numerator of the equation, ATC^ minus ATCk.j , is simply the incremental annualized treatment cost in going
from Option k-1 to Option k. The denominator is similarly the incremental removals achieved hi going from Option
k-1 to Option k.  Thus, cost-effectiveness measures the incremental unit cost of pollutant removal of Option k (in
pounds-equivalent).

        Cost-effectiveness values of options may be compared incrementally to current treatment by using the same
formula and setting the benchmark costs (ATC^j) equal to zero. The benchmark pollutant loadings (PEj-.j) are then
set equal to the current at-stream loading.

7.      Comparisons of Cost-Effectiveness Values

        Two types of comparisons are typically done using cost-effectiveness values.  Compliance costs (y axis)
and pollutant removals (x axis) may be plotted to derive a marginal cost curve to determine which options offer the
most cost-effective regulatory control. Alternatively, the cost-effectiveness of regulatory options incremental to the
baseline scenario can be used to assess the cost-effectiveness of controls relative to previously promulgated effluent
limitations guidelines for other industries.  Because only the  final rule is analyzed in this cost-effectiveness report,
graphical representation  of the incremental effectiveness of control options is unnecessary.  As  at proposal, the
comparison of incremental cost-effectiveness values for the rule is  from treatment that is already  hi place.13
    13The final rule is less expensive and more cost-effective than the option that was not selected.

                               SECTION 3: CHANGES SINCE PROPOSAL


         The April 10, 1992 notice of proposed rule-making included an analysis of the cost-effectiveness of the
 effluent limitations and guidelines for the pesticide manufacturing industry. The results of the analysis as presented
 at proposal  are briefly reviewed below.  Changes that have  occurred in the analysis  since proposal are then
 presented.
         Table 2 summarizes the findings of the cost-effectiveness analysis of the Treated Discharge Option at
 proposal.  As the table indicates, the BAT cost-effectiveness was about $10 per pound-equivalent. The PSES cost-
 effectiveness was $1.00 per pound-equivalent.14

        For the final rule, facilities that have actually closed since 1986 are not included in the economic impact
analysis or in the cost-effectiveness analysis.15 In addition, in response to public comments on the proposed rule,
EPA has re-estimated compliance costs for several facilities.16  Finally, between the proposed rule and the final
rule, the toxic weighting factor (TWF) for one pollutant included in the analysis, organo-tin, decreased from 17,829
      The reported costs are the full costs of compliance, some of which will be borne by the government in the
form of decreased tax receipts.  The analysis therefore overstates the burden of the regulations on industry.

    15For a complete discussion of the number of facilities subject to compliance costs and the revisions to those
costs, refer to the final EIA.

    16Estimated investment costs at one facility have increased from $1.6 million to $16 million since proposal (see
Chapter 4 of the Final EIA).  This change in estimated compliance costs resulted from public comments by the
facility. EPA maintains that the actual compliance costs for this facility would be lower than the estimates used in
the final analysis.  However, analysis using these higher cost estimates ensures that EPA does not underestimate
the burden of compliance at this facility.

rule, the toxic weighting factor (TWF) for one pollutant included in the analysis, organo-tin, decreased from 17,829
to 357.  The smaller TWF for organo-tin reflects the updating of the human toxicity value used in the calculation
of the TWF. A revised bioconcentration factor for organo-tin resulted in the change in the human toxicity value.
The change in the TWF for organo-tin did not have any material effect on the overall cost-effectiveness of the final
rule.

        Under the final rule,  there are 55  facilities that are expected to incur compliance  costs:  33 direct
dischargers and 23 indirect dischargers.17  As under the proposed rule, however, several facilities are excluded
from the cost-effectiveness analysis because pollutant removal data are not available; see Appendix F for more
details.  Twenty-five direct dischargers and 19 indirect dischargers are included in the analysis.

        Total annualized costs for compliance with BAT are estimated at $14.8 million (1981 dollars).  Under
PSES, the estimated total annualized compliance costs are now $4.17 million (1981 dollars) for Subcategory A
PAIs.18
     17 One of these facilities is both a direct and indirect discharger.
     '"Cost-effectiveness values are reported in 1981 dollars for comparisons with previous rules.

                                         SECTION 4:  RESULTS

        The cost-effectiveness analysis is based on the Agency's estimates of the full cost of compliance and
wastewater pollution removals associated with a Best Available Technology (BAT) option for direct dischargers and
a Pretreatment Standard for Existing Sources (PSES) option for indirect dischargers.

        The cost-effectiveness analysis includes 25 direct discharging facilities and 19 indirect discharging facilities.
These numbers are smaller than the total number of facilities expected to incur costs under the regulation (33 directs
and 23 indirects) because, as discussed in Appendix F, facilities are excluded from the cost-effectiveness analysis
if pollutant loading data were not available.19  Some  facilities expected to incur only monitoring costs required
by permitting authorities are included in the analysis even though monitoring is not required by the rule.

4.1     Best Available Technology

        A combination of treatment  technologies is employed to treat a facility's wastewater.  Some pollutant
discharge to surface water remains under the rule. Table 3 presents the cost-effectiveness data and  results for direct
dischargers. As shown in the table, the cost-effectiveness for the final rule is $14.41 per pound-equivalent removed
(Subcategory A).20

4.2     Pretreatment Standard for Existing Sources

        A combination of technologies is employed to treat a facility's wastewater prior to discharge to a sewer
or to a publicly-owned treatment works (POTW). The cost-effectiveness analysis of indirect dischargers measures
removals as the  change in at-stream pollutant loadings (after the wastestream has passed through  the POTW).

        Table 3 presents the cost-effectiveness data and results for indirect dischargers for the final rule. As shown
in the table, the  cost-effectiveness for the rule is $17.50 per pound-equivalent removed for Subcategory A.
    19One facility has both direct and indirect discharges.
    20For comparative purposes, cost-effectiveness values are reported in 1981 year dollars.

 SECTION 5: COMPARISON OF COST-EFFECTIVENESS VALUES WITH PROMULGATED RULES

        Table 4 presents the cost-effectiveness values for effluent limitations guidelines and standards issued for
direct dischargers in other industries.  The BAT rule for pesticide manufacturers is relatively cost-effective when
compared to the cost-effectiveness values for other effluent limitations guidelines.

        Table 5 presents  the  cost-effectiveness values for effluent limitations guidelines issued for  indirect
dischargers in other industries.   As with BAT, the PSES rule for pesticide manufacturers is cost-effective when
compared to the cost-effectiveness values for other effluent limitations guidelines.

Notes:
* These pollutants are volatile priority pollutants. Therefore, the human health criteria (organisms only)
   has been replaced with the criteria for (water and organisms). See text for discussion.
a. The TWF for copper is reported for these compounds since the complexes could release copper into the environment
b. The TWF of metham sodium (vapam) is used for these compounds due to structural similarity.
c. The TWF of warfarin is used for this compound due to structural similarity.
d. The TWF of hyamine 2389 is used for these structurally similar quaternary ammonium compounds.
e. The TWF of dodecylguanidine monoacetate is used for this compound due to structural similarity.
f. The TWF of benzethonium chloride is used for this compound due to structural similarity.
g. The TWF of ferbam is used for this compound due to structural similarity.
h. The TWF for the base metals of these compounds is reported assuming the toxicity is mainly due to the bound metal.
i. The TWF for tributyltin oxide is reported for these compounds since it is the most probable PAI related pollutant in wastewaters.
j. The TWF of 2-fluoroacetamide is used for this compound due to structural similarity.
k. The TWF of bolstar \ sulprofos is used for this compound due to structural similarity.

      APPENDIX F:  FACILITIES EXCLUDED FROM THE COST-EFFECTIVENESS ANALYSIS
        This  appendix provides information on the number of facilities excluded from the cost-effectiveness
analysis.  To be included in the cost-effectiveness analysis for a regulatory option, a facility must incur compliance
costs under that option, and  must have an associated removal value under the option.  A removal value of zero
under an  option is a valid possibility.  The matching of removal values and costs is done by subcategory at the
facility level.  Matching at the pollutant level is not possible since removal of priority pollutants cannot be explicitly
tied to specific costs.  The number of facilities that incur  costs but are not included in the analysis is discussed
below by discharge type.

1.      Number of Facilities Incurring Costs

        Under the final rule there are 55 facilities projected to incur costs.  These 55 facilities are categorized as
33  direct dischargers  (including five zero dischargers that  reuse,  recycle,  deep-well inject or incinerate their
wastewater) and 23 indirect  dischargers (one facility is  a joint discharger with both direct and indirect effluent
discharge).

2.      Number of Direct Dischargers in Cost-Effectiveness Analysis

        The five facilities that are currently zero dischargers are not included in the effluent loadings file and their
monitoring compliance costs  are therefore not included in the cost-effectiveness analysis.  Three additional direct
discharging facilities have effluent loadings that could not be accurately measured, and are also omitted from the
analysis.  Dropping these facilities results in 25 direct discharging facilities included in the cost-effectiveness
analysis.

3.      Number of Indirect Dischargers in Cost-Effectiveness Analysis

        Four  indirect discharging facilities have effluent levels that could not be accurately measured.  Although
wastewater quantities are known (allowing calculation of compliance costs),  pollutant concentrations within the
wastewater were not measurable.  Therefore,  there are 19 indirect facilities that have both  effluent removal values
and compliance costs under the final rule.

           APPENDIX G:  SENSITIVITY ANALYSIS OF POTW REMOVAL EFFICIENCY
        This appendix describes a sensitivity analysis applied to the assumption in the cost-effectiveness analysis
that pesticide active ingredients (PAIs) are not removed by POTWs.21  There is very little empirical data on the
PAI removals actually achieved by POTWs. The only data available on POTW removal efficiencies for PAIs are
from the Domestic Sewage Study (DSS) (Report to Congress on the Discharge of Hazardous Waste to Publicly
Owned Treatment Works, February 1986, EPA/530-SW-86-004).  The DSS provides laboratory data under ideal
conditions to estimate biotreatment removal efficiencies at POTWs for different organic PAI structural groups.
These data, however, are not full-scale/in-use POTW data and are therefore not appropriate for use in the cost-
effectiveness analysis.

        For the sensitivity analysis it is assumed that POTWs remove 50 percent of the PAIs from the wastestream.
Based on this 50 percent removal assumption, under the final rule, Subcategory A removals would be 15,509
pounds, or 119,430 pounds-equivalent, at an annualized cost of $4,165,939 (see Table G.I).  Thus, the cost-
effectiveness would be $268.62 per pound removed, or $34.88 per pound-equivalent. Even under these assumptions
the regulation remains  cost-effective.

                                              Table G.I

* Total removals include water removals as well as air removals from volatile organic compounds that are
captured and otherwise would have been released.
        This discussion applies only to indirect discharging facilities, since effluents from direct dischargers do not
 enter a POTW.
