Pesticide Chemicals Category, Formulating, Packaging and 
Repackaging Effluent Limitations Guidelines, Pretreatment Standards, 
and New Source Performance Standards; Supplemental Notice

AGENCY: Environmental Protection Agency.

ACTION: Supplemental notice to proposed rule.

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

SUMMARY: EPA is publishing this Supplemental Notice to obtain public 
comment on two topics for which comments were received on the proposed 
rulemaking (59 FR 17850, April 14, 1994) for the Pesticides 
Formulating, Packaging and Repackaging (PFPR) Industry. EPA seeks 
comment on the scope and applicability of the rulemaking as they 
pertain to commenters' requests for the exemption of certain pesticide 
active ingredients (PAIs) and certain wastewater discharges from the 
rulemaking.
    In addition, EPA is soliciting comment on a regulatory option under 
consideration by the Agency that is comprised of two alternatives 
between which industry may choose: (1) Achieving zero discharge or (2) 
incorporating specific pollution prevention (or best management) 
practices and treatment technologies and achieving an allowable 
discharge of small quantities of pollutants.
    EPA's addition of the pollution prevention alternative to achieving 
zero discharge provides benefits to the environment by reducing the 
cross-media impacts that would otherwise occur from hauling and 
incinerating the non-reusable portion of PFPR wastewaters. The 
provision of an alternative compliance method also provides flexibility 
to industry in meeting the effluent limitations guidelines and 
standards. Reducing the scope of the rule will reduce regulatory burden 
without compromising environmental protection. This notice also 
solicits comment on various means of implementing a pollution 
prevention alternative to zero discharge.
    EPA has estimated the compliance costs and economic impacts 
expected to result from a rule comprised of a zero discharge and a 
pollution prevention alternative (referred to as the Zero/P2 Option) as 
specified in this notice. The Agency has determined that the Zero/P2 
Option will result in a similar removal of toxic pound equivalents per 
year [[Page 30218]] (approximately 30 million toxic pound equivalents) 
as the proposed zero discharge option alone. At the same time, the 
Zero/P2 Option is expected to result in a reduced annualized cost 
($32.7 million in $1988 or $39.4 million in $1995) and fewer facility 
closures (no facility closures) and line closures (162) than would 
result from the zero discharge option in the proposed rule. EPA has 
determined that the Zero/P2 Option is economically achievable.

DATES: Comments on the proposed rule must be received in writing by 
July 10, 1995 at the following address.

ADDRESSES: Send comments in writing to Ms. Shari H. Zuskin, Engineering 
& Analysis Division (4303), U.S. EPA, 401 M Street SW., Washington, DC 
20460.

I. Background

    In a Notice of Proposed Rulemaking on April 14, 1994 (59 FR 17850), 
EPA proposed effluent limitations guidelines and standards for the 
control of wastewater pollutants from the Pesticide Formulating, 
Packaging and Repackaging (PFPR) industry. This proposed rulemaking 
would have established a zero discharge limitation of wastewater 
pollutants for almost all of the formulating, packaging and repackaging 
of FIFRA registered pesticide active ingredients. Only a small number 
of PAIs were not completely covered by the proposed zero discharge.
    As result of disproportionate economic impacts, EPA proposed a 
partial exemption for the exterior wastewaters 1 from small 
sanitizer facilities. Small sanitizer facilities were defined as those 
facilities which formulate, package or repackage 265,000 lbs/yr or less 
of all FIFRA registered products containing one or more sanitizer 
active ingredients (listed in Table 8 of the regulation) and no other 
active ingredients at a single pesticide producing establishment (i.e., 
a single PFPR facility). The production cutoff of 265,000 lbs/yr 
represents the production level (of these sanitizer products) at the 
largest facility that would experience economic impacts if there was no 
exemption of wastewater treatment requirements for non-interior 
wastewater sources. (See Section II.A. of this notice for a description 
of revisions made to this exemption).

    \1\ At the time of proposal, exterior wastewaters included: 
exterior equipment cleaning water, floor wash, leak and spill 
cleanup water, safety equipment cleaning water, DOT aerosol test 
bath water, air pollution control scrubber water, laboratory rinsate 
and contaminated precipitation runoff.
---------------------------------------------------------------------------

    EPA based the zero discharge limitation on pollution prevention, 
recycle/reuse and, when necessary, treatment through the Universal 
Treatment System (UTS) for reuse. EPA visualized the UTS as a flexible 
system consisting of a variety of treatment technologies that have been 
determined to be effective for treating PFPR wastewaters. In 
calculating compliance costs, EPA included costs for treatment 
technologies such as emulsion breaking, hydrolysis, chemical oxidation, 
metals precipitation and carbon adsorption. EPA also included costs for 
contract hauling treatment residuals (sludges) from the UTS for 
incineration. Because of the estimates of reduced wastewater volumes 
based on the increase in reuse/recycle practices, the overall volume of 
wastewaters being contract hauled off-site for incineration was not 
expected to increase. Thus, EPA did not include additional costs for 
contract hauling of PFPR wastewaters in the original proposal. Based on 
comments, revised costs for the proposed zero discharge option have 
been included in this notice.
    The public comment on the proposed rule was originally 60 days and 
was extended for 30 additional days. EPA received 93 individual comment 
letters, including those requesting an extension of the comment period. 
The subject of the comments spanned a variety of topics, including 
changes to scope of the regulation, EPA's pesticide cross-contamination 
policy and its effect on the industry's ability to meet zero discharge, 
increased cross-media impacts due to contract hauling of wastewater for 
incineration to meet zero discharge, and requests for a discharge 
allowance when following specific pollution prevention practices.
II. Changes to Scope

    A large portion of the comment letters addressed issues concerning 
the scope and applicability of the proposed regulation. Many commenters 
requested that the partial exemption of the listed sanitizer active 
ingredients be expanded to be a total exemption from the regulation for 
all antimicrobial active ingredients. Others requested that the 
exemption for sodium hypochlorite (bleach) be extended to other ``pool 
chemicals.'' Commenters also requested that EPA exempt from the 
regulation certain low risk PAIs, such as cloves and citronella; 
specific wastewater sources such as aerosol leak test water, safety 
equipment cleaning water, laboratory equipment rinse water and storm 
water; and experimental/ research facilities. In response to the 
information and data supplied by commenters, EPA is considering whether 
to revise some aspects of the scope of the proposed PFPR effluent 
guidelines. EPA is using today's notice to solicit comment on these 
issues.
    If the Agency determines to exclude any of the pollutants discussed 
in this section of the notice from the scope of the rule, PFPR 
facilities that discharge such pollutants directly into navigable 
waters (i.e., direct discharge PFPR/Manufacturers) will still need to 
comply with the general NPDES permitting requirements, including the 
possible establishment by the permitting authority of case-by-case 
effluent limitations based upon Best Professional Judgement (BPJ) under 
CWA section 402(a)(1)(B). (See 40 CFR 125.3). In addition, those PFPR 
facilities that indirectly discharge such excluded PAI pollutants to 
navigable waters through a [[Page 30219]] POTW would remain subject to 
the Pass Through and Interference prohibitions contained in the general 
pretreatment regulations (40 CFR 403.5(a)(1)). PFPR facilities that are 
indirect dischargers of the excluded PAIs could also be subject to 
local limits established by the POTW receiving the facility's 
wastewater (40 CFR 403.5(d)).

A. Sanitizers

    A large number of the comments received by EPA were requests for an 
exemption for antimicrobial products from the scope of the regulation. 
Although EPA did propose to partially exempt a list of sanitizer active 
ingredients due to economic reasons (i.e., disproportionate economic 
impacts), commenters requested expansion of this list. In today's 
notice EPA is soliciting comment on the exemption of indoor/home use 
and similar institutional sanitizer products from the regulation in 
addition to those sanitizer active ingredients initially listed in 
Table 8 of the proposed regulation (See Appendix A to this notice). The 
exemption would apply to both interior and exterior wastewater sources 
and would no longer be limited by a maximum production level because it 
is no longer solely based on disproportionate impacts (see discussion 
on production cutoff in Section I). However, EPA is not planning to 
exempt sporicidals or industrial preservatives. EPA has also included, 
in Appendix A, a list of those PAIs that are considered, under FIFRA, 
to be inert ingredients when used with antimicrobial active 
ingredients.
    In addition to economic impacts, EPA believes that there are a 
number of other factors to be considered in broadening the scope of the 
proposed sanitizer exemption. First, these indoor home use sanitizer 
products are formulated for the purposes of their labeled use to ``go 
down the drain'' (i.e., toilet bowl cleaners and tub and tile 
cleaners). All labels for registered products, including the use and 
disposal statements, are reviewed by EPA. Second, these same chemicals 
go to Publicly Owned Treatment Works (POTWs), possibly in higher 
concentrations and volumes, from their approved labeled use in homes 
than from equipment cleaning at PFPR facilities. Third, EPA has not 
been able to identify any reported upsets to POTWs caused by these 
sanitizer active ingredients. EPA did receive biodegradation data for 
some of these sanitizer active ingredients which supports a hypothesis 
that these PAIs also do not pass through POTWs. Finally, these 
sanitizer active ingredients represent a large portion of the low 
toxicity PAIs considered for regulation at the time of proposal.
    For the purpose of exempting indoor/home use (and similar 
institutional) sanitizers, EPA would make use of the following 
definition in the final regulation:

    Sanitizer Products means pesticide products that (1) contain the 
sanitizer active ingredients listed in Table 8 of the regulation and 
no other active ingredient; or (2) pesticide products that are 
intended to disinfect or sanitize, reducing or mitigating growth or 
development of microbiological organisms including bacteria, fungi 
or viruses on surfaces or inanimate objects in the household and or 
institutional environment, as provided in the directions for use on 
the product label. The only institutional antimicrobial products 
which are included by this definition are those with formulations 
similar to the household sanitizer products.

    For the purposes of identifying the PAIs which EPA is considering 
exempting from the scope of this rule and in order to estimate 
compliance costs to the industry for this notice, EPA was able to use 
the 1988-1991 FATES (FIFRA and TSCA Enforcement System) database which 
was previously used in developing costs for the proposal. In addition 
to the database, EPA used the definition shown above to construct the 
expanded list of sanitizer active ingredients that would receive an 
exemption from the final regulation. The expanded list of exempted 
sanitizer active ingredients used to develop revised compliance costs 
is contained in Appendix A, Table 1 of this notice. The discussion of 
estimating the revised compliance costs is contained in Section IV of 
this notice. EPA solicits comment on both the definition and its use, 
and whether to use the definition in conjunction with a list or to use 
a list only.

B. Pool Chemicals

    In the proposed regulation EPA exempted sodium hypochlorite 
(bleach) from the pretreatment standards. EPA solicited comment on 
additional chemicals that should also be excluded along with sodium 
hypochlorite. Commenters suggested that several other chemicals, that 
are mainly used in the swimming pool industry, including calcium 
hypochlorite, potassium hypochlorite, lithium hypochlorite, chlorinated 
isocyanurate compounds and several halogenated hydantoins should be 
included in this exemption.
    EPA did not include these ``pool chemicals'' in the exemption, at 
the time of proposal, because EPA believed that the formulating, 
packaging and repackaging of these chemicals did not involve the use of 
water (e.g., dry production). After review of the comments and a site 
visit to a ``pool chemicals'' facility, EPA understands that although 
the products are dry, the addition of water is necessary in certain 
instances.
    Throughout the course of normal dry operations, small amounts of 
product fall on the floor or accumulate on equipment surfaces and 
become contaminated with ordinary dust and dirt. These chemicals act as 
strong oxidizing agents and left untreated, the sweepings pose a 
serious fire and safety hazard. Facilities treat (de-activate) these 
chemicals with the addition of water and neutralizing chemicals such as 
sodium hydroxide or sodium carbonate. With this treatment, the 
available chlorine in the water is converted to a pH neutral salt which 
can be discharged to the POTW.
    Commenters also provided additional reasons for the sodium 
hypochlorite exemption, stating that the chemical does not survive in 
the sanitary waste stream and would be converted to sodium chloride 
long before it reaches the POTW. Commenters supplied data on the 
degradation of sodium hypochlorite in water. This data is available for 
review in the public record for this notice. In addition, EPA notes 
that calcium hypochlorite, potassium hypochlorite and lithium 
hypochlorite exhibit similar chemistry and half-lives as sodium 
hypochlorite. EPA also received comment requesting the extension of the 
exemption to sodium carbonate, phosphoric acid and hydrochloric acid. 
Phosphoric acid and hydrochloric acid fall under the original sanitizer 
exemption and sodium carbonate is considered an inert ingredient when 
used in formulations with other sanitizer chemicals; therefore, EPA 
does not believe it is necessary to list these chemicals under the pool 
chemicals exemption. EPA is considering whether to exempt the chemicals 
on Table 2 in Appendix A from these categorical pretreatment standards 
(PSES and PSNS) in the final regulation. In addition, EPA is 
considering using a definition for pool chemicals in conjunction with 
the list in Appendix A. This would provide more flexibility to newly 
registered chemicals that are deserving of the pool chemicals exemption 
to receive it in the future. EPA solicits comment on a definition for 
this group of chemicals.
C. Other PAIs

    Based on comments received, EPA performed a more extensive 
investigation to develop options for appropriate treatment technologies 
for certain PAIs. Upon completing this [[Page 30220]] more recent 
evaluation, EPA was left with two groups of PAIs for which insufficient 
information was available to identify best available control 
technologies. The two groups are identified as microorganisms and 
mixtures and are discussed below. In addition, comments were received 
requesting the exemption of specific low risk pesticides that fall into 
the ``mixtures'' grouping.
1. Microorganisms
    EPA is considering whether to exclude microorganisms that are 
registered for pesticidal use, such as Bacillus thuringiensis, from 
these regulations. Although, EPA has little information on the 
formulation, packaging and repackaging of such pesticides or the 
generation and characteristics of wastewaters from such operations, EPA 
believes these ``pesticides'' are not formulated in a similar fashion 
as other PAIs covered by the proposed rule. Microorganisms which have 
registered pesticidal uses are generally created through a fermentation 
process, similar to those found in some food processing plants. 
Fermentation is a biological process, where as other pesticides are 
manufactured and formulated through chemical and physical processes.
    In addition, almost all the microorganisms registered as pesticide 
products are exempt from the requirement of obtaining a (residue) 
tolerance for pesticide chemicals in or on raw agricultural commodities 
(40 CFR 180.1001). Under Part 180 Subpart D - Exemptions From 
Tolerance- it states that ``an exemption from a tolerance shall be 
granted when it appears that the total quantity of the pesticide 
chemical in or on all raw agricultural commodities for which it is 
useful under conditions of use currently prevailing or proposed will 
involve no hazard to the public health.'' Also, some of these 
microorganisms will not survive in aquatic environments, and therefore, 
pose no harm to aquatic life. These microorganisms are listed in 
Appendix A of this notice. EPA solicits comment on the exemption of 
these pesticides from the PFPR regulation.
2. Mixtures
    EPA had difficulty in finding information on appropriate treatment 
technology options for a second group of PAIs, which will be referred 
to as ``mixtures.'' This group of mixtures represents those PAIs that 
are made up of a number of substances. The molecular weights, 
solubilities and aromaticity of these pesticides are not easily defined 
because they are comprised of a variety of compounds. For example, oil 
of eucalyptus contains cineole, alpha-pinene, phellandrene, terpineol, 
citronellal, geranyl acetate, eudesmol, eudesmil acetate, piperitone 
and volatile aldehydes.
    This group of mixtures can be separated into two subgroups. The 
first subgroup of mixtures was the subject of several comments 
requesting exemption for these PAIs from the proposed rule. This first 
subgroup contains active ingredients that are plants, extracts from 
plants, non-toxic household items, foods or constituents of foods. In 
addition, many of these pesticides have been determined to be Generally 
Regarded As Safe (GRAS) under Food and Drug Administration (FDA) 
regulation (20 CFR 170.1). Examples of these pesticides include: oil of 
anise, rosemary herbs, thyme herbs, cloves, oil of citronella, lanolin, 
cottonseed oil, soybean oil, oil of lemongrass, cedarwood oil, soap and 
sawdust. EPA is considering whether to exclude this subgroup of 
mixtures from the PFPR effluent guidelines regulation. The list of 
these mixtures can be found in Appendix A of this notice. EPA solicits 
comment on the exclusion of these pesticides and requests information 
on additional pesticides which should be included in this group of 
mixtures.
    The other subgroup of mixtures is not as easily defined. This 
subgroup also contains mixtures of a number of substances of varying 
nature whose identifying characteristics are not easily identified. EPA 
has not been able to identify treatability data for these pesticides in 
the available literature. Many of these mixtures, such as kerosene, 
petroleum distillate oils, xylene range aromatic solvent and heavy 
aromatic naphtha, are typically found in the organic chemicals industry 
or are used as inert ingredients in the PFPR industry; however, in some 
instances they have been registered for pesticidal uses. EPA does not 
believe there is sufficient data to exclude these PAIs from this 
regulation; therefore, EPA is considering whether to reserve regulation 
of these types of pesticides and evaluate them at a later time. 
Specific identification of this subgroup of mixtures is contained in 
Appendix A of this notice.
3. PAIs That Have Been Determined Not to Pass Through
    As discussed in the preamble to the proposed regulation, under the 
pesticide manufacturing effluent limitations guidelines and 
pretreatment standards, EPA found that four organic chemicals 
considered to be priority pollutants did not pass through POTWs (59 FR 
17872). The four chemicals are phenol, 2-chlorophenol, 2,4-
dichlorophenol and 2,4-dimethylphenol (58 FR 50649; September 28, 
1993). In addition to being a priority pollutant, phenol is considered 
a PAI under the proposed PFPR effluent guidelines.
    EPA did not propose to exempt these four chemicals from the PFPR 
effluent limitations and categorical pretreatment standards. EPA 
proposed to establish a categorical pretreatment standard of zero 
discharge. EPA based this zero discharge standard upon the technology 
of recycling, reuse, treatment, and/or off-site disposal, which would 
be most likely shown by ``no flow'' of a PFPR facility's entire process 
wastewater stream. EPA found that PFPR facilities do not typically 
isolate their process wastewater streams; therefore the four ``no pass 
through'' pollutants would not be discharged in a separate wastewater 
stream. The zero discharge standard (premised upon a no flow 
technology) applied equally to all PAIs and priority pollutants, 
resulting in the removal of pass through pollutants and the incidental 
removal of those four pollutants that do not pass through. Thus, the 
Agency determined that it was unnecessary to exempt any PAI or priority 
pollutant from the pretreatment standards on the basis that it does not 
pass through a POTW. (59 FR 17872).
    However, EPA is considering whether to add a pollution prevention 
alternative (see Section III) to the regulation which would provide for 
an allowable level of discharge where facilities are performing 
specified pollution prevention practices. With this proposed 
alternative, EPA believes it would be appropriate to exclude phenol, 2-
chlorophenol, 2,4-dichlorophenol and 2,4-dimethylphenol from regulation 
in these categorical pretreatment standards (PSES and PSNS) for this 
alternative because they have been found not to pass through and 
facilities would no longer have to achieve no flow of process 
wastewater. EPA solicits comments on this determination.
D. Wastewater Sources

    Commenters requested exemption of Department of Transportation 
(DOT) aerosol leak test water, safety equipment cleaning water, 
laboratory rinsates and storm water from the definition of process 
wastewater. After reviewing the information and data supplied by 
commenters and performing additional data gathering, EPA believes that, 
in certain situations, these wastewaters should be exempted from the 
rule.
    DOT aerosol leak test baths are used by PFPR facilities that 
package their [[Page 30221]] products into aerosol cans. The leak test 
is performed as a requirement prior to transporting the cans. Test 
baths must be kept at 130 deg.F, cans must be fully submerged, and the 
baths must be visually monitored for leaking or bursting cans.
    EPA believes that unless there are leaking or bursting cans, the 
water in the bath should not contain pollutants from the formulations. 
When facilities are not using continuous overflow baths, they will 
change the water periodically. This is usually due to the build up of 
small amounts of oil and grease from the exterior surface of the cans 
themselves (or the silk screened labels). EPA is considering whether to 
exclude discharges from DOT test bath water from the rule when a 
facility operates a batch bath where no leaks have been detected or 
where cans have not burst from the time of the last water change out. 
EPA solicits comment on this exclusion (See Section III for a 
discussion on non-excluded DOT test bath water and the pollution 
prevention alternative.)
    EPA has also reexamined the inclusion of discharges from safety 
equipment cleaning water in the rule. Commenters requested the 
exemption of safety equipment cleaning water from the zero discharge 
requirement on the basis that it contains only small amounts of 
pollutants. Commenters also stated that a zero discharge limitation on 
discharges from safety equipment cleaning waters would create a 
disincentive for testing safety showers and eye washes and would create 
worker safety problems. Safety showers and eye washes are typically 
tested by running water through the equipment long enough to ensure 
that water is flowing freely to the unit and that associated alarms are 
functioning. EPA proposed exempting wastewater discharges from the 
operation of employee showers, laundry facilities and the fire 
protection equipment test water for similar reasons, including worker 
safety issues. In addition, the water from testing this safety 
equipment should not contain any pesticide active ingredients or other 
pollutants of concern. Therefore, EPA is considering whether to exclude 
discharges from the testing of safety showers and eye washes from 
coverage under the final rule. However, other wastewater associated 
with cleaning safety equipment, such as rinsing respirators or boots, 
would still be covered by the rule and the pollution prevention 
alternative (see Section III) as it would be expected to contain some 
level of pollutants. EPA solicits comment on this exclusion.
    Laboratory equipment rinse water is another wastewater source which 
commenters considered to contain low levels of PAIs. Typically, a 
finished product is analyzed prior to packaging as part of the 
facility's quality control program. A small sample, referred to as the 
retain sample, is taken into the laboratory for testing.
    EPA believes that the only measurable amounts of PAI would come 
from the retain sample itself and the container that is used to bring 
it into the laboratory. Facilities can usually reuse the retain sample 
back into a future formulation of the same product. Wastewaters 
originating from water that is used to rinse other laboratory 
glassware, such as graduated cylinders, beakers and pipets should 
contain non-detectible levels of pesticide active ingredients. In 
addition, while performing analytical testing other chemicals may be 
used to perform extractions and render the glassware rinsates non-
reusable. Therefore, EPA is considering whether to exclude wastewater 
discharges from cleaning analytical equipment in on-site laboratories 
from these regulations. However, EPA would not be excluding wastewater 
from the retain sample itself or the water used to clean the container 
that is used to bring the sample into the laboratory. EPA solicits 
comment on this exclusion.
    In the proposed regulation, EPA included contaminated precipitation 
runoff (storm water) that collects in tank farms, secondary containment 
structures or on loading pads. Commenters requested the exclusion of 
storm water from the zero discharge regulation because it was not 
reusable and because storm water is covered by the Storm Water 
Regulations (57 FR 41297; September 9, 1992).
    In the proposed regulation, EPA suggested the use of the Universal 
Treatment System (UTS) for achieving zero discharge for wastewaters 
that could not be reused directly into product. EPA suggested that, for 
example, floor wash could be treated through the UTS and reused as 
floor wash. Commenters disagreed with this suggestion in terms of storm 
water, stating that storm water cannot not be reused for its original 
purpose following treatment.
    In addition, comments were received on the redundancy of the 
proposed effluent guidelines regulations with the storm water 
regulations (57 FR 41297). In response to comment, EPA has reviewed the 
recent storm water regulations and has made a determination that except 
for the repackaging establishments, storm water at PFPR facilities is 
already covered by the individual or general NPDES permits issued to 
cover storm water from industrial activity. For general permits and 
most individual permits, the storm water regulations require a very 
detailed pollution prevention plan which must contain a list of site 
specific best management practices, plans for employee training, and 
schedules for inspections. EPA believes that the pollution prevention 
plan required by the storm water regulations mandates practices similar 
to those outlined in the pollution prevention alternative (see Section 
III.B.3.). To avoid duplicative regulatory coverage, EPA is considering 
whether to exempt storm water discharges from the PFPR rule for the 
Subcategory C facilities (which does not include repackaging 
establishments). (See Section II.E for a discussion on the change from 
``refilling establishments'' to ``repackaging establishments.'')
    The coverage of storm water at repackaging establishments is not as 
clearly defined. The primary SIC code describing repackaging 
establishments is SIC 5191 and is not specifically included as one of 
the SIC codes covered under the definition of industrial activity (55 
FR 47990) in the storm water regulations (although storm water in 
storage areas including tank farms is included). EPA believes a gap may 
be created if storm water from repackaging establishments is not 
covered in the PFPR effluent guidelines or the storm water regulations. 
EPA also believes that storm water collected from secondary containment 
at repackaging establishments where refilling of agricultural 
pesticides into minibulk containers is conducted, is not different than 
the type of storm water collected from tank farms at PFPR facilities. 
EPA solicits comment on the inclusion of the requirements for general 
storm water permits (i.e., storm water pollution prevention plan) into 
the PFPR guidelines for Subcategory E facilities (repackaging 
establishments) or into the storm water regulations under a separate 
rulemaking.
    In addition, EPA believes that the possible contamination of storm 
water at repackaging establishments can be reduced through use of good 
housekeeping practices, closed loop refilling systems and small 
enclosures or roofs around pumps and valves. EPA solicits comment on 
these or other best management practices associated with repackaging 
establishments that could be employed to reduce the level of wastewater 
pollutants found in storm water at these facilities. EPA also requests 
comment from repackaging establishments that are not able to reuse 
[[Page 30222]] storm water or rinsates as make up water for use in 
applications, if it is in accordance with the product label.

E. Clarification of Definitions

    Commenters requested clarification on several issues and 
definitions in the proposed regulations. Commenters requested specific 
definitions for formulating, packaging and repackaging, as well as, 
clarification between pesticide formulating and pesticide manufacturing 
when they occur at the same facility. Clarification was also requested 
for the determination that on-site incineration meets the requirements 
of zero discharge for this regulation. The definition of repackaging 
establishments, particularly in reference to ``retail sales,'' also 
prompted comment.
    EPA considers the formulation of pesticide products to mean the 
process of mixing, blending or diluting one or more PAIs with one or 
more active or inert ingredients, without a chemical reaction that 
changes one active ingredient into another active ingredient, to obtain 
a manufacturing use product or an end use product. EPA considers the 
packaging of pesticide products to mean enclosing or placing a 
formulated pesticide product into a marketable container. EPA considers 
the repackaging of pesticide products to mean the direct transfer of a 
single PAI or single formulation from any marketable container to 
another marketable container, without intentionally mixing in any 
inerts, diluents, solvents, other ingredients or other materials of any 
sort.
    Pesticide manufacturers may sometimes add a solvent to a 
manufactured PAI or intermediate for the purpose of stabilizing 
transport or at the request of the formulator who is receiving the PAI 
as a raw material. EPA would like to clarify that manufacturers can 
perform such operations without being subject to the PFPR effluent 
guidelines. Typically, such operations are performed without placing 
the pesticide in a marketable container (i.e., they are shipped in bulk 
via tank truck, rail car or tote tank). However, PFPR facilities should 
not conclude that they can receive PAIs (that they do not manufacture), 
even in bulk quantities, and dilute it with solvent or other carrier 
without being subject to the PFPR effluent guidelines, as this would be 
considered formulating.
    Although EPA proposed zero discharge limitations with pollution 
prevention, recycle/reuse and treatment for reuse as the basis for the 
zero discharge limitation, facilities may meet the requirement of zero 
discharge to water through a number of other options. Most of these 
options include hauling wastewater to off-site destinations. These 
destinations include incinerators, deep wells and commercial waste 
treaters and, in some cases, wastes are returned to the registrant or 
manufacturer. EPA received comment requesting clarification of on-site 
incineration as a means of achieving zero discharge. For purposes of 
this regulation only, EPA considers on-site incineration a valid option 
for achieving zero discharge of PFPR process wastewater. Wet scrubbing 
devices used for air pollution control on these on-site incinerators 
are not subject to the PFPR effluent guidelines. The only existing on-
site incinerators at facilities covered by the PFPR regulation are at 
facilities which also manufacture pesticide active ingredients. 
Scrubber wastewater discharges from these incineration activities are 
currently regulated under the pesticide manufacturing effluent 
guidelines (58 FR 50638, September 28, 1993) for the PAIs manufactured 
at these facilities.
    Based on comments received, EPA intends to clarify how the PFPR 
effluent guidelines would apply to refilling establishments. EPA 
proposed that the PFPR limitations and standards (proposed Section 
455.60) would apply to refilling establishments that repackage 
agricultural pesticides whose primary business is retail sales (59 FR 
17904). This is the same scope used in the proposed Standards for 
Pesticide Containers and Containment regulations (59 FR 6712, February 
11, 1994). EPA chose to specify a subset of the universe of refilling 
establishments within the proposed containment rule to require 
secondary containment only at agricultural pesticide refilling 
facilities where there was documented evidence of environmental 
contamination from leaks and spills. Specifically, EPA believed that it 
did not have sufficient information regarding the practices and 
environmental problems at formulators and manufacturers where pesticide 
refilling may occur to prescribe containment requirements (59 FR 6754).
    EPA received comments from State of Minnesota officials on the 
proposed PFPR effluent guidelines stating that there are refilling 
establishments whose business is primarily wholesale sales located in 
their state that repackage agricultural chemicals into refillable 
containers.
    The EPA believes that in an attempt to be consistent with the 
language in the proposed containment regulations, it may have misstated 
the intended scope of the PFPR effluent guidelines. EPA believes that 
the types of refilling establishments used as the basis for 
extrapolating data to all refilling establishments in the PFPR industry 
included facilities whose primary business is wholesale and/or retail 
sales and did not include pesticide formulators or manufacturers or 
repackagers of non-agricultural pesticides.
    EPA intends to clarify the scope of Subpart E of the proposed PFPR 
effluent guidelines, Sec. 455.60. However, this change in the 
definition, may cause the regulated community confusion, as there would 
be two definitions of the term ``refilling establishment.'' Therefore, 
EPA is considering keeping the term refilling establishment for the 
Container regulations and using the term repackaging establishments for 
the final PFPR effluent guidelines. In this situation Sec. 455.60 would 
read ``a repackaging establishment is an establishment where the 
activity of repackaging agricultural pesticide product into refillable 
containers occurs, whose primary business is wholesale or retail sales, 
and where no pesticide manufacturing, formulating, or packaging 
occurs''. EPA solicits comment on this clarification.

III. Pollution Prevention Alternative

    This section discusses the background on the pollution prevention 
alternative incorporated in the Zero/P2 Option, including the comments 
received which led to today's supplemental notice and solicitation for 
comments. The structure of the alternative and the pollution prevention 
(P2) practices are described. The notice solicits comment on the degree 
to which these practices should be specified in the regulatory text 
(i.e., specified vs. guidance). The wastewater treatment cost savings 
and pollutant loading reductions that are associated with the P2 
practices are briefly discussed. In addition, several options for 
implementation of the P2 alternative on which EPA seeks comment are 
described including self-certification, submittal of a plan to 
permitting authorities, and greater flexibility for the permitting 
authorities to use best professional judgement (BPJ).
    In response to the zero discharge proposal, a variety of commenters 
stated that PFPR facilities should be given the opportunity to conduct 
various pollution prevention practices and thereby limit the level of 
PAIs which would be discharged into navigable waters. Commenters cited 
to a list of such practices that the Agency had already developed in 
its Development Document for the proposed rule. These same commenters 
argued that the zero discharge limitations and standards 
[[Page 30223]] were inappropriate given the non-water quality 
environmental impacts that would arguably result from the increased 
amount of incineration of process wastewater that would need to occur. 
Commenters also raised concerns about the costs of the proposed zero 
discharge standard.
    Given these set of comments concerning costs and non-water quality 
impacts, EPA believes that it is appropriate to consider a pollution 
prevention (P2) alternative to the proposed zero discharge limitations 
and standards. As described in more detail below, PFPR facilities would 
generally have a choice of either meeting the relevant zero discharge 
standard or limitation or choosing to conduct the listed P2 practices 
as set forth in Tables B-1 and B-2 of this supplemental notice. Two 
variations in the structure of the P2 alternative are discussed below, 
they vary in the practices that would be specified in the regulatory 
text of the final regulation (see Section III.C.3).
    For either variation of the pollution prevention alternative chosen 
for final promulgation, those PFPR facilities which choose to conduct 
the P2 practices would need to also agree to make the P2 alternative 
enforceable, e.g., direct dischargers would need to agree to have the 
P2 practices included in their NPDES permits and indirect dischargers 
would need to file notices of intent to use the P2 practices with the 
POTW. (See Part III.C.4 for discussion and solicitation of comment on 
several approaches that EPA anticipates could be utilized to implement 
the P2 alternative.)
    If a PFPR facility chooses to adopt the P2 alternative by 
conducting the P2 practices, agreeing to its enforceability, complying 
with specified record keeping requirements, and, in certain instances, 
treating the process wastewater, the facility would be permitted to 
discharge those levels of PAIs and priority pollutants which remain in 
the process wastewater stream. The Agency believes that the level of 
PAIs and priority pollutants remaining in the process wastewater should 
be considerably reduced and, in most cases, should pose no 
environmental harm.
    Direct dischargers of the covered PAIs which choose to adopt the P2 
alternative in lieu of meeting the zero discharge limitations may be 
subject to the establishment by the permitting authority of more 
stringent effluent limitations based on applicable water quality 
standards. See 40 CFR 122.44. In addition, those PFPR facilities that 
are indirect dischargers which adopt the P2 alternative would remain 
subject to the Pass Through and Interference prohibitions contained in 
the general pretreatment regulations. 40 CFR 403.5(a)(1). Indirect 
dischargers which choose to be subject to the P2 alternative could also 
be subject to local limits established by the pretreatment authority 
receiving the facility's wastewater. 40 CFR 403.5(d).

A. Authority

    EPA believes that promulgation of this pollution prevention 
alternative is authorized under the Clean Water Act (CWA) for a number 
of reasons. In promulgating Best Available Technology Economically 
Achievable (BAT) effluent limitations, EPA is authorized to consider a 
number of factors, including, among other things, non-water quality 
environmental impacts (including energy requirements) (CWA section 
303(b)(2)(B)). In addition, in establishing BAT limitations, EPA is to 
identify the degree of effluent reduction attainable, e.g., the level 
of pollutant removal attained through implementation of the effluent 
limitation (CWA section 304(b)(2)(A)). While not required under the 
CWA, EPA also evaluates the cost-effectiveness of the BAT effluent 
limitations.
    Pretreatment Standards for Existing Sources (PSES) under CWA 
section 307(b) are designed to prevent the discharge of pollutants that 
pass through, interfere with, or are otherwise incompatible with the 
operation of POTWs. The CWA authorizes EPA to establish pretreatment 
standards for pollutants that pass-through POTWs or interfere with 
treatment processes or sludge disposal methods at POTWs. The 
legislative history of the 1977 Act indicates that pretreatment 
standards are to be technology-based and analogous to the BAT effluent 
limitations for removal of toxic pollutants. Thus, in proposing the 
zero discharge PSES limitation, EPA analyzed the same factors which 
were assessed for the proposed BAT zero limitation standard.
    For example, in proposing the original BAT and PSES effluent 
limitations and the standards for new sources for PFPR facilities, EPA 
determined that zero discharge represents the best available and that 
zero discharge was economically achievable for the PFPR industry (59 FR 
17891 and 17898). EPA also estimated the pounds of pollutants removed 
under a zero discharge limitation and determined that such a limitation 
option was cost-effective by estimating the cost per toxic pound 
equivalent removed from PFPR process wastewaters (59 FR 17894-99). EPA 
also evaluated the non-water quality environmental impacts by assessing 
the effects a zero discharge limitation and standard would have on air 
pollution, solid waste generation, and energy requirements (59 FR 
17900). Based upon those evaluations and analyses of the other factors 
to be considered in promulgating the BAT and PSES effluent limitations, 
the Agency found zero discharge to be an appropriate limitation for 
pollutants in wastewater from PFPR facilities.
    However, in response to the proposed rule, a number of commenters 
argued that EPA had underestimated the non-water quality environmental 
impacts of a zero discharge limitation. In particular, commenters 
stated that air pollution would increase because of the increased use 
of incineration as an option for disposal of process wastewater. In 
addition, commenters argued that energy requirements resulting from BAT 
and PSES zero discharge limitations would be greater than those 
estimated by EPA because of the increased consumption of fuel for use 
in transporting wastewater to incineration facilities or deep well 
injection sites and the increased fuel needed for burning these dilute 
wastewaters in an incinerator.
    In response to these comments, EPA re-evaluated its position on the 
degree to which the non-water quality environmental impacts effect this 
regulation and now recognizes that under a zero discharge BAT or PSES 
limitation for this industry, significantly increased amounts of 
process wastewater that cannot be recycled, reused, or treated may be 
transported to incinerators for disposal (resulting in an increase in 
air emissions) and that increased amounts of energy may have to be used 
for such transport and for incineration of these dilute wastewaters.
    Neither this revised assessment of non-water environmental quality 
impacts or the revised economic assessment (see Section V) alter EPA's 
determination that a zero discharge limitation is an appropriate BAT 
and PSES limitation for pollutants in PFPR process wastewater. However, 
in response to concerns raised by commenters about the costs and non-
water quality environmental impacts of the zero discharge option, EPA 
believes it is appropriate to consider the Pollution Prevention (P2) 
alternative presented by these commenters.
    To evaluate economic impact and economic efficiency, EPA has 
grouped the zero discharge proposal and the P2 alternative as proffered 
by commenters into the Zero Discharge/P2 Option [[Page 30224]] (Zero/P2 
Option). Under this Option, all PFPR facilities subject to the final 
rule would have a choice of either meeting the zero discharge 
limitation (or pretreatment standard) or employing the P2 practices and 
discharging the small amount of PAI pollutants that remain in the 
process wastewater.
    EPA believes that this Zero/P2 Option addresses both the economic 
cost and non-water quality environmental impacts which commenters 
believed were not adequately considered by the Agency in its proposed 
zero discharge option. As discussed in more detail in Section V, under 
the Zero/P2 Option both the costs impacts and the cost effectiveness 
compare favorably to the proposed Zero Discharge Option alone. 
Moreover, the Zero/P2 Option will reduce the level of adverse non-water 
quality environmental impacts which may occur in comparison to those 
resulting from a Zero Discharge limitation and standard alone by using 
pollution prevention practices to decrease the use of cross-media 
transfers (off-site disposal to incineration, deep-well injection, 
central waste treaters, etc. * * *).
    Under the Zero/P2 Option, PFPR facilities would need to agree to 
implement the listed P2 practices in lieu of complying with the zero 
discharge limitation or standard and also agree to make compliance with 
the P2 practices enforceable. For PFPR facilities that directly 
discharge (only PFPR/Manufacturers) the covered PAIs into navigable 
waters, EPA believes that the P2 alternative is authorized under the 
CWA as a system of best management practices (``BMPs'') that may be 
incorporated into any NPDES permit. (CWA section 304(e)). BMPs are 
defined, in part, to mean ``schedules of activities, prohibitions of 
practices, maintenance procedures, and other management practices to 
prevent or reduce the pollution of ``waters of the United States * * 
*.'' 40 CFR 122.2 EPA believes that the list of pollution prevention 
practices contained in Tables B-1 and B-2 fit within that definition. 
The NPDES regulations authorize permitting authorities to include BMPs 
in NPDES permits under a number of conditions. 40 CFR 122.44(k). EPA 
believes that incorporation of these pollution prevention practices as 
BMPs into an NPDES permit is authorized because they carry out the 
purposes and intent of the CWA. 40 CFR 122.44(k)(3).
    EPA recognizes that in the proposed rule, the Agency took the 
position that regulating PFPR facilities on a nationwide basis through 
the use of BMPs may not be appropriate because they may not provide the 
needed flexibility for the many different facilities subject to any 
final rule (59 FR 17901, April 14, 1994). However, EPA has provided for 
the needed flexibility in the Zero/P2 Option by making only certain 
pollution prevention practices mandatory if a facility chooses the P2 
alternative, i.e., those practices contained in Table B-1. The other 
pollution prevention practices (Table B-2) may be modified under a 
variety of circumstances. In addition, EPA is soliciting comment on a 
variation of the P2 alternative where only practices which directly 
reduce pollutant loadings to wastewater are specified in the regulatory 
text and where water conservation practices are only provided as 
guidance (see Section III.C for discussion on this variation).
    For PFPR facilities that discharge covered PAIs into navigable 
waters indirectly through a POTW, EPA believes that the Zero/P2 Option 
is appropriate as an alternative pretreatment standard under CWA 
section 307(b) and does not conflict with the implementation of the 
general pretreatment regulations. 40 CFR Part 403. Pretreatment 
standards for existing and new sources are designed to prevent the 
discharges of pollutants that pass through, interfere with, or are 
otherwise incompatible with the operations of POTWs. (CWA 307(b)).
    As stated above, in establishing pretreatment standards for 
existing and new facilities, EPA is authorized to evaluate the same 
factors that it assesses in establishing BAT limitations. In assessing 
the removal of pollutants from wastewater, the cost impact, cost 
effectiveness, and non-water quality impacts of the P2 alternative for 
both the Zero Discharge proposed PSES and PSNS standards and the P2 
alternative, EPA has found that the P2 alternative (as part of the 
Zero/P2 Option) compares either favorably (cost impact, cost 
effectiveness, non-water quality impacts) or similarly (pollutant 
removal) with the Zero Discharge Option. Thus, EPA believes that it is 
appropriate to consider the P2 alternative as pretreatment standards 
for existing and new sources.

B. Background

    As discussed in Section I, EPA proposed a zero discharge regulation 
for wastewaters generated by the formulating, packaging and repackaging 
of pesticide products, with the exception of exterior wastewaters from 
facilities formulating, packaging and repackaging certain sanitizer 
active ingredients. The basis for the proposed zero discharge 
regulation was pollution prevention, recycle/reuse and treatment and 
reuse when necessary. EPA received comment on the technical feasibility 
and economic achievability of the proposed zero discharge regulation. 
Many comments focused on circumstances where wastewater was not 
completely reusable. Commenters requested that EPA reduce both the 
cross-media and economic impacts associated with the proposed 
regulation.
    One situation where commenters believe complete reuse is not 
achievable concerns EPA's existing policy on cross-contamination. 
Currently, EPA sets a standard of zero for cross-contamination. This 
means that an active ingredient may not be present at any concentration 
in a FIFRA registered product where it is not listed on the 
confidential statement of formula (CSF) of that product. During the 
study phase for the development of the proposal, the industry practice 
was to triple rinse containers and equipment. Because of recent EPA 
enforcement actions, industry commented that additional rinsing is 
being used to comply with the cross-contamination policy. EPA is 
currently reviewing the pesticide cross-contamination policy.
    Commenters believe that more aggressive enforcement of a zero-
standard cross-contamination policy would create additional wastewaters 
that would not be reusable and that were not taken into account when 
the proposed zero discharge regulation was developed. According to 
commenters, a facility that performs a triple rinse of the equipment 
interiors when changing from formulating one product to another, may 
have to perform additional rinses (e.g., a five times rinse) to ensure 
a level of zero cross-contamination. Commenters stated that even in 
cases where the rinsate from the multiple rinse could be stored for use 
in a future formulation, the additional rinses create more rinsewater 
than could be reused and that these very dilute wastewaters would have 
to be contract hauled for off-site disposal to achieve zero discharge. 
Commenters believe this additional contract hauling of wastewater not 
only makes the proposed regulation economically unachievable, but 
increases the opportunity for cross-media impacts.
    A second situation described by commenters focuses on the need for 
periodic blowdown of the treatment system. Commenters believe that even 
when using an appropriate treatment system, such as the Universal 
Treatment System (UTS), continuous reuse is not technically feasible 
(i.e., PFPR wastewater is not reusable indefinitely). Commenters state 
this is due to a [[Page 30225]] buildup of salts in the system that 
would require a periodic blowdown to maintain a well operated treatment 
system. To achieve zero discharge this blowdown wastewater would have 
to be contract hauled for off-site disposal, increasing the economic 
impact to the industry and increasing the opportunity for cross-media 
transfers.
    The third situation described by commenters concerns the reuse of 
water following treatment. In the proposed regulation, EPA 
demonstrated, in the discussion on estimation of compliance costs, that 
it did not expect facilities to reuse wastewaters that had been treated 
directly into product or for cleaning equipment interiors (59 FR 
17876). Although some facilities do reuse treated wastewaters in this 
way, only interior rinsates that could be reused without treatment and 
could, therefore, be directly reused into formulation or stored for 
reuse in a future formulation of the same or compatible product formed 
the basis for the proposed zero discharge. EPA recommended that 
wastewaters that needed treatment prior to reuse could be reused for 
their original purpose (i.e., treated floor wash can be used to wash 
floors). However, commenters felt that EPA did not account for 
wastewaters that could not be reused for their original purpose such as 
interior wastewaters that could not be stored due to concerns for 
microbial growth or interior wastewaters generated when changing a 
formulating or packaging line from a solvent-based product to a water-
based product. EPA notes that cost estimates for the proposed 
regulation did include costs for contract hauling similar excess 
wastewaters for off-site incineration. However, EPA does recognize 
that, as stated previously, contract hauling these wastewaters for 
incineration may increase economic and cross-media impacts.
    Due to the concerns described above, many commenters requested a 
discharge allowance for these excess or non-reusable wastewaters. 
Commenters suggested that they would be willing to agree to use 
specified pollution prevention or best management practices and pointed 
to the pollution prevention, recycle and reuse practices described in 
the preamble to the proposal (59 FR 17866) and the technical 
development document [EPA #821-R-94-002]. In some cases commenters 
provided examples of possible additional practices they would be 
willing to agree to use. EPA believes that a discharge allowance 
(``pollution prevention allowable discharge'') may provide an added 
incentive to increase the use of pollution prevention and recycle 
practices while ensuring that facilities are maximizing pollutant 
reductions in the wastewater without increasing cross-media impacts.
    The following sections describe the possible variations in the 
structure of the pollution prevention alternative, the practices which 
may be included as part of final regulation for either variation, and 
the various approaches for implementing the final rule.

C. Structure of the Alternative

    For purposes of soliciting comment on today's supplemental notice, 
two variations of the structure of the pollution prevention 
alternative, as they might appear in the final regulation are discussed 
below. EPA has also provided possible regulatory text in Appendix B of 
this notice to assist commenters in focusing their written comments. 
Appendix B to this notice focuses on a version of the P2 alternative 
which would list all the pollution prevention, recycle and reuse 
practices that would be specified in the final regulatory text. The 
other version of the P2 alternative would specify, in the final rule, 
only those pollution prevention, recycle and reuse practices that 
directly reduce pollutant loadings in the wastewater, while only 
recommending the use of the water conservation practices and equipment 
as guidance. For example, in this case the use of a floor scrubber 
would not be specified in the regulation; however, floor wash from 
cleaning liquid production area floors would still require treatment 
prior to being considered a P2 allowable discharge. Thus, floor 
scrubbers would be recommended because they can reduce the size and 
cost of the treatment system by reducing the volume of wastewater 
requiring treatment. (See Section III.C.4 for a discussion on an 
implementation approach which could increased the use of BPJ in 
reference to the specified practices).
    EPA believes that although most facilities would choose to use both 
the specified and recommended practices, this approach may be more 
difficult to permit and enforce. Also, this approach does not ensure 
that the total pounds of pollutants in the discharged wastewaters are 
at desirable levels. Without the use of certain flow equipment devices, 
the maximum reusability of certain wastewater sources, particularly 
interior equipment rinsates, may not be possible (i.e., facilities may 
have too much rinsewater volume than is called for in the formulation). 
In addition, in the case where water conservation practices are not 
incorporated into the final regulatory text, the use of dilution to 
achieve the P2 allowable concentrations may be encouraged.
    In addition to soliciting comment on these variations, EPA is 
soliciting comment on the approach related to implementation of the 
pollution prevention alternative. (See Section III.C.4. for a 
discussion on implementation).
1. Alternative to Zero
    The pollution prevention alternative has been designed to serve as 
an alternative to the proposed zero discharge regulation. This means 
that if a facility agrees to comply with the prescriptive practices 
(and any local limits which may be more stringent) and make them 
enforceable, the facility would be allowed a discharge allowance (P2 
allowable discharge). However, if a facility does not agree to comply 
with the requirements of the alternative they would be subject to a 
zero discharge limitation or standard.
2. Definition of Pollution Prevention Allowable Discharge
    EPA has extensively evaluated the definition of the P2 allowable 
discharge for use in the pollution prevention alternative. EPA is not 
planning to set a numerical definition of P2 allowable discharge for 
many of the same reasons that EPA did not set numerical limitations and 
standards in the proposed regulation (59 FR 17875). Briefly, the 
reasons included the lack of data, such as long term monitoring data 
necessary to set numerical limitations, lack of analytical methods for 
testing for many of the PAIs in wastewater, and the large annual cost 
that would be associated with compliance monitoring for all PAIs that a 
PFPR facility may use in production over a year's time.
    In general, the definition as described would require that, in 
addition to performing the specified practices, certain waste streams 
be treated (or pretreated) prior to being eligible for consideration as 
an ``allowable discharge.'' In order to allow additional flexibility, 
EPA is considering allowing permitting authorities (NPDES or 
pretreatment authority) to use BPJ to make a special modification to 
this definition in which treatment would not be necessary for a 
specific facility. EPA solicits comments on the use of a special 
modification to the definition. The remainder of this section focuses 
on the definition of pollution prevention allowable discharge.
    Use of a definition for P2 allowable discharge should account for 
the difference between waste streams of high concentration and other 
waste streams (e.g., interior wastewaters, floor [[Page 30226]] wash 
and spill and leak cleanup water versus DOT test bath water or safety 
equipment cleaning water). Due to the additional pollutant removals 
afforded by treatment at the POTW, EPA has developed similar but 
separate definitions for indirect and direct dischargers. In brief, 
treatment would be required for any waste streams discharged to the 
nation's waters by direct dischargers. The definition of P2 allowable 
discharge for direct dischargers will be discussed later in this 
section. The definition of P2 allowable discharge for indirect 
dischargers that send wastewater to POTWs is constructed as a two-part 
definition, which would apply to waste streams of different raw 
concentrations.
    For PFPR process wastewaters, excluding interior equipment 
cleaning, floor wash and spill and leak cleanup water, EPA believes 
that (1) many of these sources contain lower concentrations of 
pollutants prior to pretreatment and (2) the use of the specified 
pollution practices alone will sufficiently reduce the pollutant 
loadings in the wastewater when followed by treatment at a POTW. 
However, based on raw wastewater characterization data collected on 
sampling visits to PFPR facilities, pretreatment may be necessary for 
interior equipment cleaning, floor wash and spill and leak cleanup 
water to reduce the levels of pesticide active ingredients and other 
pollutants. Thus, EPA is requesting comment on the following two part 
definition of pollution prevention allowable discharge for indirect 
dischargers:

    Pollution prevention allowable discharge (excluding interior 
wastewaters, leak/spill cleanup water and floor wash) means: the 
quantity of/concentrations in PFPR process wastewaters that remain 
after a facility has demonstrated that it is using the specified 
practices of the Pollution Prevention Alternative as listed.
    Pollution prevention allowable discharge for interior 
wastewaters, leak/spill cleanup water, and floor wash means: the 
quantity of/concentrations in PFPR process wastewaters that remain 
after a facility has demonstrated that it is using the specified 
practices of the Pollution Prevention Alternative as listed AND that 
have been pretreated using appropriate pollution control 
technologies which can be used individually or in conjunction with 
one another as listed in Appendix C, or an equivalent system to 
achieve a sufficient level of pollutant reduction. Facilities must 
demonstrate that the appropriate pollution control technology is 
properly maintained and operated.

    Appendix C contains those pollutant control technologies, such as 
hydrolysis, chemical oxidation, metals precipitation and activated 
carbon adsorption, which have been used for estimating compliance costs 
on a PAI specific basis. In general, these treatment technologies have 
been determined to be effective in treating pesticide containing 
wastewaters in literature, in bench or pilot scale treatability studies 
or in the Pesticide Manufacturing effluent guidelines.2 These are 
the same technologies that were presented as part of the Universal 
Treatment System at the time of proposal. However, these technologies 
are PAI specific and may need to be used in conjunction with one 
another to provide treatment for all PAIs used at a facility over a 
period of time. In addition, facilities may experience difficulties 
treating wastewaters that contain emulsions, therefore, ``appropriate'' 
treatment for emulsified wastewaters must include an emulsion breaking 
step.

    \2\ EPA is still determining the appropriate treatment 
technologies for a number of inorganic pesticide chemicals. 
Activated carbon (AC) adsorption was only used to provide a 
conservative cost estimate. Therefore, listed technologies for such 
PAIs are subject to change for final regulation.

    Note: EPA has costed facilities for these types of dynamic 
---------------------------------------------------------------------------
treatment needs.

    In the proposed regulation, EPA recognized that although the 1978 
regulation for the pesticides industry set a zero direct discharge 
limitation (BPT) on wastewaters generated from the formulating, 
packaging and repacking of pesticide products, some facilities were 
directly discharging PFPR wastewaters. These facilities manufacture 
pesticide active ingredients, as well as, perform PFPR activities 
(referred to as PFPR/Manufacturers in the proposed regulation) and were 
able to comply with zero discharge (BPT) by treating these wastewaters 
through the same treatment system used for treating their pesticide 
manufacturing wastewaters without an additional allowance for PFPR 
wastewater pollutants in the facility's pesticide manufacturing 
discharge limits. These facilities should be the only PFPR facilities 
currently discharging directly to the nation's waters.
    These direct discharging pesticide manufacturing facilities have 
treatment systems that are required to meet the BAT pesticide 
manufacturing limitations (57 FR 50368). However, because these 
facilities discharge directly into the nation's waters without the 
removals afforded by secondary treatment at POTWs, EPA believes that, 
unlike indirect dischargers, these facilities may have to treat all 
PFPR wastewaters. Therefore, the following definition of pollution 
prevention allowable discharge would apply to direct dischargers who 
formulate, package or repackage pesticides and manufacture pesticides.

    Pollution prevention allowable discharge (for PFPR/
Manufacturers) means: the quantity of/concentrations in all PFPR 
process wastewaters that remain after a facility has demonstrated 
that it is using the specified practices of the Pollution Prevention 
Alternative as listed AND that have been treated using appropriate 
pollution control technologies which can be used individually or in 
conjunction with Manufacturer's treatment systems or one another as 
listed in Appendix C, or an equivalent system to achieve a 
sufficient level of pollutant reduction. Facilities must demonstrate 
that the appropriate pollution control technology is properly 
maintained and operated.

    By using the above definition, EPA would be including wastewaters 
into the pollution prevention alternative generated at these facilities 
by the PFPR of pesticides that are manufactured and formulated, 
packaged and/or repackaged as well as the wastewaters from the PFPR of 
those pesticides that are not also manufactured. In the case of these 
PFPR/Manufacturers, the term ``appropriate'' pollution control 
technology takes on additional meaning than the one discussed above for 
indirect dischargers. It also implies that when the pollution control 
technology in place for treating their manufacturing wastewater is not 
identified in Appendix C, in literature, or in treatability studies as 
an effective treatment technology for a PAI that they only use in 
formulating and packaging operations, they must add to their existing 
treatment system. EPA is soliciting comment on the above definition.
    In the above definitions, for both indirect and direct discharges, 
EPA makes reference to allowable amounts of pollutants in terms of 
concentration and quantity.

    Note: EPA is considering a variation of the P2 alternative which 
would specify certain P2 practices while providing water 
conservation practices solely as guidance.

    The main purpose for including volume in the definition of P2 
allowable discharge is that in lieu of setting a mass-based definition, 
the incorporation of volume or flow reduction is meant to discourage 
the use of dilution of wastewaters to create concentrations that appear 
to be at an allowable level. In addition, EPA notes that when 
facilities use water conservation technologies to control the volume of 
wastewater they generate, they can more easily store and reuse interior 
rinsates, which may result in additional pollutant removals. Also, the 
use of flow [[Page 30227]] reduction practices or equipment reduces the 
volume of water that must be treated before it can be considered a P2 
allowable discharge. Reduced volumes require smaller treatment systems 
that, therefore, cost less to install and operate and run more 
efficiently, and in using certain technologies, such as precipitation/
clarification, will result in reduced effluent pollutant loadings. Some 
facilities may adopt flow reduction strategies to save money and 
incidentally save loadings.
    EPA believes that the definition of P2 allowable discharge can be 
implemented for this industry without the use of numerical limitations. 
In the pollution prevention alternative, EPA has included the 
requirement for paperwork that would include a discussion describing 
how a facility would demonstrate to their permitting authority (NPDES 
or pretreatment authority) that they are operating a well maintained 
treatment system (UTS or equivalent) that includes pollution control 
technologies that are appropriate for the PAIs handled at their 
facility. In addition, the paperwork would have to include the 
rationale for choosing the method of demonstration. For example, a 
facility may determine a surrogate method for determining breakthrough 
of their carbon adsorption unit. This method could be used instead of 
performing analytical testing for all or any of the PAIs that may have 
been in production at the facility over a specific period of time.

    Note: EPA will submit an ICR to the Office of Management and 
Budget concerning this paperwork prior to final promulgation.

    In addition, some indirect discharge facilities may be able to 
achieve complete pollution prevention, recycle and reuse of some 
wastewater sources, such as interior equipment cleaning rinsates, that 
would otherwise require treatment prior to being considered allowable 
discharges under the pollution prevention alternative. Such facilities 
would not have to incur the cost of treatment to discharge their 
remaining streams to the POTW (assuming no local limits requiring 
treatment). These facilities would not be operating treatment systems 
to comply with this regulation and; therefore, would not need to 
include a discussion in the necessary paperwork that demonstrates they 
are operating a well maintained treatment system. However, these 
facilities should indicate in the necessary paperwork that the 
wastewater sources which remain and which they are discharging are not 
the wastewater sources that require treatment under the pollution 
prevention alternative. In addition, there may also be facilities that 
choose comply with the zero discharge track of the Zero/P2 Option. For 
example, these facilities may choose to recycle and reuse wastewaters 
to the best of their ability and contract haul remaining wastewaters to 
avoid incurring the costs associated with installing and operating a 
treatment system.
3. Description of Pollution Prevention Practices
    EPA has developed a list of pollution prevention, recycle and reuse 
practices for the pollution prevention alternative. The list is derived 
from the pollution prevention, recycle and reuse practices that have 
been demonstrated in the PFPR industry and are documented in the public 
record to the proposed rule. (See Section 7 of the Technical 
Development Document for the proposed rule [EPA 821-R-94-002].) If 
performed, these practices will reduce the pollutant loading of the 
wastewater and reduce the volume of wastewater by creating 
opportunities for reuse. In some instances the water conservation 
aspect of the practices will discourage the practice of dilution of the 
wastewater to create concentrations that appear to be at an allowable 
level.
    For use as part of the pollution prevention alternative, the list 
has been separated into two tiers: (1) Practices that discharger must 
agree to comply with without any modification; and (2) other practices 
that discharger must agree to with acceptable justification. The second 
list has been set up to include possible modification based on comments 
received on the proposed rule or during meetings with industry. These 
modifications are discussed below. Both sets of pollution prevention, 
recycle, and reuse practices are included in Appendix B of this 
supplemental notice.
    The list of pollution prevention practices for which no 
modification is provided includes: the use of flow reduction on hoses; 
the use of good housekeeping practices such as using drip pans and 
performing preventive maintenance; specific practices concerning the 
reuse of rinsate from rinsing drums that contain liquid PAI (or inerts) 
for formulation of water-based products; the sweeping of dry production 
areas prior to rinsing; and the use of recirculation (with periodic 
blowdown) when operating air pollution control wet scrubbers and 
continuous overflow DOT aerosol leak test baths. In addition, this list 
of pollution prevention practices includes a provision for some 
equipment dedication that is contingent on the ability to reuse 
interior rinsates as discussed on the second list (See discussion 
below). In the version of the P2 alternative, where water conservation 
practices and equipment would only be included as guidance and not 
specified in the regulatory text, the list above would be modified. The 
use of flow reduction devices on hoses and the use of recirculating air 
pollution control scrubbers and DOT test baths would not be included in 
the regulatory text of the final regulation and would only be 
recommended. EPA solicits comment on the practices contained in Table 
B-1 of Appendix B and whether the water conservation practices and 
equipment discussed above should be used only in guidance.
    The second list sets forth other pollution prevention, recycle and 
reuse practices that may be modified with acceptable justification. In 
Appendix B, acceptable justification for modifying an individual 
practice is described following the description of the practice itself. 
A modification, for purposes of the pollution prevention alternative, 
means that a facility would no longer have to perform a listed practice 
or that it would need to comply with the described alternative 
practice. However, the modification only applies to the specific 
practice from the second list for which the modification has been 
justified and to no other listed practices. Facilities would be 
required to discuss all modifications in the paperwork necessary for 
the pollution prevention alternative.
    The pollution prevention, recycle and reuse practices on the second 
list include: practices concerning the reuse of rinsates from rinsing 
drums that contain liquid PAI (or inert) for formulation of solvent-
based products; the use of low volume/high pressure rinsing equipment 
for rinsing PFPR equipment interiors when rinsing with water; the use 
of floor scrubbing machines or mops for cleaning floors in liquid 
production areas; the segregation of production equipment for water and 
solvent based production; and the storage of interior equipment 
rinsates for use in future formulation of the same or compatible 
product. Water conservation equipment such as low volume/high pressure 
rinsing equipment, floor scrubbing machines, and mops and buckets that 
do not directly reduce pollutant loadings to the wastewater and, 
therefore, may not be specified in the regulatory text of the final 
rule. Instead, they may be discussed as guidance.
    Upon reviewing the comments to the proposed regulation and 
discussions [[Page 30228]] with facilities on post-proposal site 
visits, EPA has determined situations where it may be justified not to 
conduct these practices. For example, facilities may not always be able 
to store interior equipment rinsates for use in future formulation of 
the same or compatible product for a variety of reasons. These reasons 
include: microbial growth in the stored product or other deterioration 
such as phase separation or formation of precipitate; space 
limitations; dropping of product registration or discontinuation of 
production for a specific product; customer specifications (e.g., 
manufacturer/formulator for which a toll formulating contract directs 
otherwise); and the facility only packages but does not formulate the 
product. EPA is soliciting comment on the above reasons for 
modification and whether the water conservation equipment discussed 
above should be used only in guidance.
    Facilities who modify a practice must provide justification. For 
example, facilities who modify the practice of storing rinsate for 
future formulation for any of the reasons above must provide 
justification such as: evidence of microbial growth or deterioration or 
written statement from the customer for which they are contract toll 
formulating directing otherwise (e.g., the contract specifies that the 
rinsate be sent back to customer or sent for off-site disposal). In 
some instances in which modifications are allowed, specific alternative 
practices must be agreed to and conducted in addition to those in the 
list of specified practices (Table B-1, Appendix B). These specific 
alternative requirements are listed with the second list of pollution 
prevention, recycle and reuse practices in Table B-2, Appendix B and 
would be incorporated into the regulatory text at the time of 
promulgation. For example, where a facility cannot store interior 
rinsates for use in future formulation due to space limitations, the 
facility would have to store rinsates for use in future formulation of 
the same or compatible product only for their most frequently produced 
products.
    There is also a contingent practice in the first list of pollution 
prevention practices (Table B-1, Appendix B) which mandates some 
dedication of equipment that will reduce rinsates from changeover. 
Under this contingent practice, facilities would not have to dedicate 
all equipment, but instead would have to dedicate equipment in at least 
one of the following ways, by: frequently produced products (i.e., top 
production products); hard to clean products (e.g., viscous, sticky or 
colored products); product families; or a portion of the formulating/
packaging equipment (e.g., just the mix tank, just the agitator, just 
the transfer hoses). Facilities would not have to dedicate equipment 
for the same products where they cannot store the interior rinsates for 
future formulation. EPA believes such a contingent practice would be 
over prescriptive and would possibly be economically unachievable at 
some PFPR facilities. The purpose of this contingent practice for 
dedication is to avoid the generation of wastewater where plausible in 
order to off-set the wastewater generated when a facility has modified 
the specified practice. EPA solicits comment and data on the pollutant 
loadings in wastewater and the volume of wastewater saved by the use of 
dedicated equipment in any of the ways listed in the above discussion.
    In general, EPA believes that the use of the practices specified by 
the pollution prevention alternative, including practices focusing on 
water conservation, create the opportunity for increased source 
reduction through reusability of wastewaters. This would lead to large 
pollutant reductions and, in the case of water conservation practices, 
smaller, less expensive treatment systems. Use of the practices as part 
of the pollution prevention alternative (with a P2 discharge allowance) 
should also limit cross-media impacts by reducing the amount of process 
wastewater that would otherwise be transported off-site and 
incinerated.
4. Implementation of the Pollution Prevention Alternative
    This section describes several implementation options for this 
effluent guideline. EPA solicits comment from all interested parties. 
In addition, EPA hopes to provide guidance on the implementation of the 
final rulemaking through the use of a guidance manual and regional 
workshops. EPA is soliciting comment on additional forms of guidance 
that would be useful.
    EPA believes that either variation of the pollution prevention 
alternative (all practices specified vs. some as guidance only) could 
be implemented in a variety of ways. Each PFPR facility subject to this 
regulation, if promulgated with the Zero/P2 Option, will need to make 
an initial choice: to either comply with the Zero Discharge effluent 
limitation or pretreatment standard or choose to agree to conduct the 
listed pollution prevention practices and also agree to make the 
practices and the pollution prevention discharge allowance enforceable. 
However, beyond this initial choice, the continued implementation of 
the Zero/P2 Option will differ for direct and indirect dischargers.
    For direct dischargers, the Zero/P2 Option will be implemented 
through the NPDES permitting process. For each direct discharging PFPR/
Manufacturer or new facility, the facility would need to make the 
initial choice at the permitting or permit renewal stage. If the 
facility chooses the P2 alternative over the zero discharge limitation, 
the permitting authority would include all of the P2 practices and the 
specified treatment technologies in the facility's NPDES permit. The 
pollution prevention practices and treatment technologies included in 
such a NPDES permit would be enforceable under CWA sections 309 and 
505.
    PFPR facilities which are indirect dischargers would also need to 
make an initial choice of meeting the zero discharge pretreatment 
standard or adopting and implementing the P2 practices and the 
treatment technologies (if so specified). If the indirect discharging 
PFPR facility chooses the P2 alternative, EPA would propose that the 
facility file a Notice of Intent (NOI) with the pretreatment authority. 
In addition, indirect discharging PFPR facilities which choose the P2 
alternative would need to self-certify in writing that they are 
performing the listed practices or provide the necessary justification 
for modifying certain of the pollution prevention practices as listed 
in Table B-2. This certification would require a signature by the 
appropriate manager in charge of overall operations of the facility to 
assure that information provided is true, accurate, and complete to the 
best of his or her knowledge. The pretreatment authority, as part of 
its approved pretreatment program, must have the authority to ensure 
compliance with a pretreatment standard (40 CFR 403.8(f)(1)(ii)) and to 
carry out inspections of the indirect dischargers' self-certifications 
and of the paperwork described below. 40 CFR 403.8(e)(1)(v).
    Both direct and indirect discharging facilities would be required 
to keep certain paperwork on-site and available for permitting 
authorities and enforcement officials. For each facility, this 
necessary paperwork would include, at a minimum, descriptions of the 
practices that are being employed and how they are being implemented, 
discussions of any modifications that are made and the justification 
for each modification (including records that indicate, for example, 
microbial growth, space limitations, infrequent or intermittent 
production). The necessary paperwork must also include: (1) A 
discussion on demonstrating that the treatment system being used 
contains [[Page 30229]] the appropriate treatment technologies (i.e., 
listed by PAI in Appendix C or equivalent established in literature) 
for removing PAIs that are used in production at their facility and 
could be in their wastewater; (2) and establishes a method for 
demonstrating that the treatment system is well operated and 
maintained; and (3) the rationale for choosing the method of 
demonstration.
    Permitting authorities could, after receipt of the NOI or at the 
time of issuing, reissuing, or modifying the NPDES permit, inspect the 
PFPR facility to see that the listed practices are being employed, that 
the treatment system is well operated and maintained and that the 
necessary paperwork provides sufficient justification for any 
modifications. EPA solicits comment on this approach to implementation 
of the pollution prevention alternative.
    EPA also requests comment on a second implementation option. 
Instead of utilizing self-certification, this approach could require 
facilities to submit the necessary paperwork to the permit writer or 
pretreatment authority for approval. For this option, EPA is requesting 
comment on whether the submitted paperwork should support the practices 
as listed in Appendix B of this notice or be based on the practices 
listed in Appendix B, but allow flexibility to the permitting 
authority. More specifically, the permitting authority could add to or 
replace practices in Appendix B with new or innovative practices that 
are more effective at reducing the pollutant loading (directly or 
indirectly) from a specific facility to the environment, based on best 
professional judgement (BPJ). EPA realizes that requiring submittal of 
paperwork to and approval from the permitting authority would increase 
the burden and may cause untimely delays in implementing this option. 
In addition, EPA believes that it may be difficult for the permitting 
authority to review a facility specific plan that is not based wholly 
on the listed practices found in Appendix B of this notice. This 
approach may provide more flexibility for the industry and the 
permitting authority; however, it will substantially increase the 
burden on the permitting authorities.
    As in other effluent guidelines and pretreatment standards, the 
compliance deadline for the PFPR pretreatment standards for existing 
sources would be three years following promulgation and the date of 
issue, reissue or modification of the NPDES permit for direct 
discharging PFPR/Manufacturing facilities. New source standards and 
limitations (PSNS and NSPS) must be complied with when a facility 
commences the discharging of wastewater.
IV. Costing Methodology

    This section will briefly describe the revisions that have been 
made to the costing methodology that was used to estimate compliance 
costs and the pollutant removals for the proposed rule. These revisions 
are discussed more thoroughly in the updated version of the Cost and 
Loadings Report and the Treatability Database Report which can be found 
in the public docket.
    In addition to the changes that are made due to the revisions to 
the scope that are being considered (as discussed in Section II), there 
are three areas where changes have been made to the costing 
methodology. These include revisions to: (1) The treatability database 
to include activated carbon adsorption (AC) as the treatment technology 
for certain PAIs where additional treatability information has been 
identified; (2) the costs for the zero discharge alternative to include 
costs for off-site incineration of non-reusable wastewaters; and (3) 
the computer model used to develop costs and pollutant removals for the 
proposed rule to estimate compliance costs and pollutant removals for 
the pollution prevention alternative.
    In order to adjust the estimated compliance costs and pollutant 
loadings to account for the exemption of specific PAIs and wastewater 
sources (see Section II for discussion of exemptions), EPA had to 
remove the PAIs from the influent database. In addition, EPA had to 
make adjustments to account for the volume of wastewater previously 
contributed by the PFPR of these PAIs. In the situation where exempted 
PAIs are the only PAIs used in a product or on a line, it is not 
difficult to zero out the associated pollutant removals, treatment cost 
estimates or the wastewater related to production of the exempted PAIs. 
However, when exempted PAIs are used in conjunction (in products or on 
shared lines) with PAIs that are covered by the rule, only the 
pollutant loading contributed by the exempted PAIs can be excluded; the 
total wastewater related to the production must still be costed. A more 
extensive description on the revisions to wastewater volumes due to the 
exemption of certain PAIs (including PAIs with non-surveyed production) 
can be found in the updated Cost & Loadings Report. These revisions 
tend to reduce an individual facility's annualized compliance cost 
estimates as compared to the proposed rule.
    EPA revised the treatability database to assign activated carbon as 
the treatment technology for certain PAIs where additional treatability 
information has been identified. In addition to deciding which 
treatment technologies were appropriate for these PAIs through 
literature searches and technology transfers, EPA used the same 
transfer basis as was used in the proposal to transfer achievable 
effluent concentrations (i.e., the 90th percentile highest achievable 
effluent concentration) for these PAIs. This information was added to 
the treatability database for the PFPR industry. This revision tends to 
increase annualized compliance cost estimates for some facilities as 
compared to costs estimated at proposal.
    In addition to the overall revisions above, revisions were made 
specifically to the cost estimates for achieving zero discharge of 
wastewater for the proposed rule. In the proposed rule, EPA only 
included costs for contract hauling to off-site incineration of 
treatment system sludges. Based on comment, EPA has revised the costing 
methodology for the zero discharge option to reflect additional 
contract hauling of interior equipment rinsates to off-site 
incineration, and to account for possible water balance problems. 
Interior equipment cleaning rinsates from lines where detergents or 
solvents were used are now costed for contract hauling for off-site 
incineration rather than treatment and reuse. Based on comment, EPA 
also increased overall, the percentage of the blowdown (bleed off 
stream) from the UTS. This revision accounts for the volume of 
wastewater that cannot be reused due to either a salt buildup or a 
water balance problem at the facility. The percent for blowdown has 
been increased from 0.2% in the proposed rule to 5% in this notice.

    Note: EPA continued to use a blowdown of 0.2% for estimations 
for the pollution prevention alternative, because under this 
alternative facilities can discharge these excess wastewater under 
the P2 discharge allowance.

    A third revision was made which was applied to both the revised 
zero discharge cost estimates and those estimated for the pollution 
prevention alternative. For the proposal, EPA costed directly reusable 
rinsewaters that were stored for longer than 90 days to be treated 
prior to reuse. This conservative approach was used to address the 
Resource Conservation and Recovery Act (RCRA) limitation for 
accumulating hazardous wastes for more than 90 days without a permit or 
interim status (40 CFR 262.34). Instead, EPA is using a more realistic 
approach by assuming that since these rinsewaters [[Page 30230]] are 
directly reusable (i.e., do not require treatment prior to reuse, and 
due to stringent product specifications, do not contain constituents 
that are not used in the product) they would not be considered a waste, 
and therefore, would not trigger the 90 day RCRA accumulation 
limitation on listed or characteristic hazardous wastewaters. 
Therefore, EPA has revised the cost model so that it no longer costs 
stored interior equipment cleaning rinsates that have been stored for 
greater than 90 days for treatment through the UTS. Instead, these 
reusable rinsewaters are costed for storage only (not RCRA storage 
costs).

    Note: To avoid speculative accumulation, 75% of these directly 
reusable rinsewaters must be reused within a calendar year.

    Estimated annualized compliance costs to achieve zero discharge 
tend to decrease due to changes in scope, but increase in the aggregate 
due to the three revisions described in the above discussion as 
compared to the proposed rule.
    Finally, EPA also developed estimated annualized compliance costs 
and pollutant removals for the pollution prevention alternative. This 
cost estimate is based on the version of the P2 alternative which would 
specify the pollution prevention, recycle and reuse practices in the 
regulatory text of the final rule (see Section III.C). However, it can 
also be viewed as a conservative estimate for the P2 alternative where 
water conservation practices are not specified in the regulatory text, 
but are instead provided as guidance.
    The computer model used for estimating costs was altered slightly 
to estimate costs for the pollution prevention alternative. Capital 
costs were added to account for equipment (e.g., cost of floor 
scrubbing machine or other flow reduction devices) needed to perform 
the specific practices. In reference to this equipment, EPA applied an 
80% reduction to floor wash and exterior equipment cleaning volumes. 
Also, revisions were made to include removing the cost of pretreatment 
for the wastewater sources that would not require treatment prior to 
discharge to a POTW (e.g., DOT aerosol test bath water or safety 
equipment cleaning). [Note: EPA has not estimated costs for direct 
discharging stand alone PFPR facilities because these facilities are 
currently considered to be at zero discharge]. Wastewaters that would 
require treatment prior to discharge under a pollution prevention 
discharge allowance were costed for treatment through the UTS 
(including a 0.2% blowdown costed for contract hauling sludges for 
incineration). As mentioned above, EPA did not include costs for 
treating interior equipment cleaning rinsates that are stored for 
greater than 90 days. In addition, interior equipment cleaning rinsates 
from lines where detergents were used were costed for treatment and 
discharge under the P2 discharge allowance. In the cases of indirect 
dischargers, many facilities benefited from the decrease in the size of 
the UTS necessary to treat their wastewater remaining after utilizing 
the specified practices. For the purpose of conducting the economic 
analysis, including determining the incremental cost-effectiveness (see 
Section V), EPA revised the costs and loadings of Option 2 (from 
proposal) to reflect the costs and loadings associated with the 
pollution prevention alternative. Both the pollution prevention 
alternative and Option 2 from the proposal are based on pollution 
prevention with treat and discharge; however, the pollution prevention 
alternative would only allow reduced discharge and is designed so that 
it would not have to require numerical limitations for compliance, as 
did Option 2 in the proposal.
    EPA requests comment on the revisions to the costing methodology.

V. Estimated Costs, Economic Impacts, and Cost-Effectiveness

A. Options at Proposal

    EPA considered 5 PSES options at proposal. Options 1 and 2 were not 
zero discharge options but involved treatment of wastewater and 
discharge to POTWs. Options 3, 4, and 5 were zero discharge options but 
involved different compliance methods with differing costs and impacts.

    Option 1 consisted of end-of-pipe treatment for all wastewaters 
through the Universal Treatment System (UTS) and discharge to POTWs. 
Option 1 was rejected because it did not include pollution 
prevention, did not incorporate the best available technology 
available and because the Agency would be unable to control the 
discharge of all pollutants due to a lack of analytical methods for 
some active ingredients. Option 1 would require significant 
additional data on a large number of pollutants for which the Agency 
would have to establish standards and for which facilities would 
need to monitor. See 59 FR 17875.
    Option 2 added pollution prevention by recycling wastewaters 
from cleaning the interiors of formulating and packaging equipment, 
and raw material and shipping containers into the product to recover 
product value in the wastewaters. Other wastewaters were still 
expected to be treated through the UTS and discharged to POTWs. 
Option 2 contained pollution prevention provisions but was rejected 
for the analytical and monitoring reasons stated above, as it still 
required numerical limitations.
    Option 3 employed the same technology and pollution prevention 
practices as Option 2 but achieved zero discharge of all process 
wastewater by recycling the wastewater back to the facility after 
treatment through the UTS. Option 3/S', the proposed option, is a 
variant on Option 3 which expanded the coverage of the regulation to 
PAIs not covered by the Section 308 survey and exempted certain 
waste streams associated with specific sanitizer PAIs from the zero 
discharge requirement.
    Option 4 incorporated the pollution prevention aspects of 
Options 2 and 3, but instead of treatment, added off-site disposal 
to an incinerator for the rest of the wastewater. Option 4 was 
rejected because it relied on transferring wastewater pollutants to 
another media and resulted in higher costs with no increased 
benefits.
    Option 5 assumed that all wastewater would be disposed of 
through off-site incineration. Option 5 was rejected because it did 
not contain any pollution prevention provisions and for the same 
reasons as Option 4.

    A complete discussion of the estimated compliance costs, impacts, 
and cost-effectiveness at proposal can be found in the Economic Impact 
Analysis of Proposed Effluent Limitations Guidelines and Standards for 
the Pesticide Formulation, Packaging, and Repackaging Industry (EIA) 
and the Cost-Effectiveness Analysis Of Proposed Effluent Limitations 
Guidelines And Standards For The Pesticide Formulating, Packaging, And 
Repackaging Industry. Both of these documents are available for review 
in the public docket of this rulemaking.
B. Compliance Costs

    For the purposes of economic analysis, EPA re-estimated the 
annualized compliance costs and economic impacts for two of the 
regulatory options presented at proposal (Options 1 and 4) to 
incorporate the changes in scope discussed in this notice. EPA also 
estimated compliance costs and economic impacts for a new regulatory 
option referred to as the Zero/P2 Option. The Zero/P2 Option consists 
of two alternatives. When implemented, facilities would either meet 
zero discharge limitations, as the proposed rule required, or would be 
allowed a reduced discharge (P2 allowable discharge) if they met 
certain pollution prevention and treatment practices. The Zero/P2 
Option revises both Options 2 and 3/S' presented at proposal, and 
incorporates them into one option, allowing industry to choose between 
these alternatives. The new pollution prevention alternative is 
different from the old Option 2 in that [[Page 30231]] the pollution 
prevention practices are specified and must be used for compliance and 
does not require numerical limitations (which could not be developed 
due to insufficient data). As stated in III.A. of this notice, the 
Agency now believes that it may also be appropriate to establish an 
alternate BAT and PSES limitations that allow a discharge of pollutants 
as long as PFPR facilities comply with certain pollution prevention 
practices. It also differs from the old Option 2 in that as part of the 
Zero/P2 Option, the Agency believes that the pollution prevention 
alternative can be implemented without the use of numerical limitations 
(see Section III.C.2). EPA did not re-estimate costs for Option 5 
because it is not a viable option given that it achieves the same 
results as the new regulatory option and Option 4 (i.e., zero 
discharge) at substantially higher costs.
    EPA previously estimated the total annualized compliance cost of 
the proposed rule at $56.1 million (1988) (which equals $67.4 million 
in 1995). EPA is using 1988 dollars because it is the base year for the 
survey data that was collected and because costs were presented in 1988 
dollars in the proposal. As shown in Table 1, total annualized 
compliance costs (including amortized capital costs and operating and 
maintenance costs) equal $32.7 (1988) million ($39.4 million in 1995) 
for the Zero/P2 Option. In choosing between the two components of the 
Zero/P2 Option, industry is expected to choose the lower cost 
compliance alternative for each facility. For some facilities, 
particularly those with low volumes of wastewater, achieving zero 
discharge will be the less expensive alternative (even when they comply 
by contract hauling wastewaters for off-site incineration); for most 
facilities, achieving the P2 allowable discharge by complying with 
pollution prevention practices and treatment of certain waste streams 
is less expensive. The cost estimate for the Zero/P2 Option selects the 
least costly alternative for each facility.
    As discussed in the proposed rule (59 FR 17896), EPA expanded the 
scope of the rule to account for facilities that formulate PAIs other 
than those PAIs covered by the 1988 survey questionnaire. In the 
proposal, EPA referred to these additional PAIs as the ``non 272'' 
PAIs. Several of the non-272 PAIs are being considered for exemption 
from the final rule (see Section II. A of this notice). Consistent with 
the methodology used at proposal, EPA assumed that facilities using 
only non-272 PAIs have the same average compliance costs, percent of 
impacted facilities, and average pollutant removals as facilities 
covered by the survey.

C. Economic Impacts

    EPA re-estimated the economic impacts resulting from the compliance 
costs using the methodology presented in the EIA for the proposed rule. 
EPA projected two categories of economic impacts that may result from 
regulation: severe impacts measured as projected facility closures, and 
moderate impacts measured as conversion of PFPR product lines to non-
pesticide formulating, packaging and repackaging operations, or 
compliance costs in excess of five percent of facility revenue. Under 
the proposed option, EPA projected facility closures at two facilities 
and moderate economic impacts at 250 facilities (see Table 1). Under 
the new combined Zero/P2 Option, EPA projects no severe impacts and 
moderate impacts at 162 facilities, a substantial decrease from the 
proposed rule.

D. Cost-Effectiveness

    Cost-effectiveness analysis is used in the effluent guidelines 
process to compare the efficiency of one regulatory option in removing 
pollutants to another regulatory option, and to compare the regulation 
with other promulgated regulations. Cost-effectiveness is defined as 
the incremental annual cost of a pollution control option in an 
industry or industry subcategory per incremental pollutant removal. The 
increments considered are relative to another option or benchmark such 
as existing treatment. The cost-effectiveness value, therefore, 
represents the marginal cost of removing the next pound of pollutant.
    For this cost-effective analysis, the costs were annualized using a 
social discount rate of seven percent. To facilitate comparison among 
rules promulgated in different years, cost-effectiveness values are 
always reported in 1981 dollars. Pollutant removals are measured in 
copper-based toxic ``pounds-equivalent''. This adjustment accounts for 
differences in toxicity among the regulated pollutants. (Note that the 
analysis presented here is not strictly comparable with that presented 
at proposal because the toxic weighting factor used for pyrethrin has 
decreased significantly since proposal as a result of a new calculation 
method.)
    Table 2 presents the total annualized costs, total pounds, total 
pounds-equivalent of pollutants removed, and average cost per pound 
removed for the three options (Options 1, Zero/P2, and 4). Table 3 
presents the incremental cost-effectiveness for the three options.

----------------------------------------------------------------------------------------------------------------
\1\ These removals are not strictly comparable with those presented in the cost-effectiveness at proposal as the
  toxic weighting factor used to calculate pound equivalent removals for Pyrethrin has decreased significantly  
  since proposal.                                                                                               
\2\ EPA is considering giving industry the choice of complying with zero discharge or the pollution prevention  
  alternative which allows a reduced discharge. This choice was proposed by industry. Option Zero/P2 combines   
  revised Options 2 and 3/S' into a single option of choice.                                                    
\3\ The removal numbers presented here are not precise. All options have virtually identical removals (2.7x10   
  \5\ pounds and 3.0x10 \7\ lb-eq). The precision with which we can estimate the removals is not precise enough 
  to accurately differentiate such small differences. The Zero/P2 Option is the least costly alternative and    
  removes approximately the same number of pounds as the other Options.                                         
\4\ Option 1 requires numerical limitations. EPA did not set numerical limitations and standards in the proposed
  regulation (59 FR 17875) because of the lack of data such as the long term monitoring data necessary to set   
  numerical limitations, lack of analytical methods for testing for many of the PAIs in wastewater, and the     
  large annual cost that would be associated with compliance monitoring for all PAIs that a PFPR facility may   
  use in production over a years time. The revised Option 1 costs presented here underestimate the true costs   
  associated with Option 1 because they only include monitoring costs associated with the original 272 PAIs.    
  They do not include monitoring costs associated with the Non-272 PAIs, because analytical methods have not    
  currently been identified for all of them.

\3\ The cost effectiveness numbers presented here are for illustrative  
  purposes only. All options have virtually identical removals (2.7x10

  estimate the removals is not precise enough to differentiate such     
  small differences. EPA has determined that the Zero/P2 alternative is 
  the least costly, and thus the most cost-effective.                   
\4\ Option 1 requires numerical limitations. EPA did not set numerical  
  limitations and standards in the proposed regulation (59 FR 17875)

  necessary to set numerical limitations, lack of analytical methods for

VI. Unfunded Mandates Reform Act

    Under section 202 of the Unfunded Mandates Reform Act of 1995 (the 
Act), P.L. 104-4, which was signed into law on March 22, 1995, EPA 
generally must prepare a written statement for rules with Federal 
mandates that may result in estimated costs to State, local, and tribal 
governments in the aggregate, or to the private sector, of $100 million 
or more in any one year. When such a statement is required for EPA 
rules, under section 205 of the Act EPA must identify and consider 
alternatives, including the least costly, most cost-effective or least 
burdensome alternative that achieves the objectives of the rule. EPA 
must select that alternative, unless the Administrator explains in the 
final rule why it was not selected or it is inconsistent with law. 
Before EPA establishes regulatory requirements that may significantly 
or uniquely affect small governments, including tribal governments, it 
must develop under section 203 of the Act a small government agency 
plan. The plan must provide for notifying potentially affected small 
governments, giving them meaningful and timely input in the development 
of EPA regulatory proposals with significant Federal intergovernmental 
mandates, and informing, educating, and advising them on compliance 
with the regulatory requirements.
    EPA has determined that the alternative Zero/P2 Option discussed in 
this notice does not include a Federal mandate that may result in 
estimated costs of $100 million or more to State, local, or tribal 
governments in the aggregate, or to the private sector, in any one 
year. EPA has estimated that the annual costs of the Zero/P2 Option to 
the private sector to be $32.7 million in 1988 dollars or $39.4 million 
in 1995). Although EPA has not empirically estimated the annual costs 
to States, local, or tribal governments resulting from implementation 
of the Zero/P2 Option, the Agency expects the annualized costs to be 
much less than those which the private sector, i.e., the PFPR 
facilities will face. States, local, or tribal governments will face 
the costs of issuing NPDES permits or conducting inspections of 
facilities; however, EPA does not expect these costs to produce any 
significant increase to the costs that these entities incur by issuing 
an NPDES permit or discharge agreement prior to the promulgation of the 
effluent limitations or pretreatment standards. EPA solicits comment on 
this estimate.
    As to section 203 of the Act, EPA has determined that the Zero/P2 
Option discussed in this notice will not significantly or uniquely 
affect small governments, including tribal governments. EPA recognizes 
that small governments may own or operate POTWs that receive wastewater 
from PFPR facilities subject to the pretreatment standards contained in 
this notice, including the Zero/P2 Option. Thus, there may be certain 
small governments which receive notices of intent from PFPR facilities 
that choose to avail themselves of the P2 alternative. These same small 
governments will [[Page 30233]] need to enforce the pretreatment 
standards through compliance mechanisms, including inspections. 
However, these mandates are already contained in the existing general 
Pretreatment Standards, which include requirements for an approved POTW 
pretreatment program. 40 CFR 403.8. Thus, EPA believes that any 
mandates resulting from this notice are not significant or unique.
    EPA has, however, sought meaningful and timely input from the 
private sector, states, and local governments on the development of 
this notice. After receiving comment on the pollution prevention 
alternative, EPA met with members of private sector who requested that 
such meetings be held to discuss this alternative. EPA shared a draft 
version of the pollution prevention alternative with the Effluent 
Guidelines Task Force, the members of which include industry, 
environmental groups, state governments, and owner/operators of POTWs. 
EPA officials also presented the pollution prevention alternative at a 
conference held by the Association of Metropolitan Sewerage Agencies, 
which includes representatives from, primarily, large and medium 
municipal sewer authorities (POTWs) from across the United States. EPA 
also plans to distribute this Federal Register notice to several 
smaller POTWs which service different small communities throughout the 
United States in an attempt to seek timely and meaningful input from 
small governments. Thus, EPA expects that any applicable requirements 
of section 203 of the Act will have been satisfied prior to 
promulgating a final rule.

VII. Solicitation of Comment

    In addition to those areas where EPA specifically requested comment 
throughout this notice, EPA solicits comment in the following areas:
     Research and development (R&D) facilities--EPA has 
received comment from stand alone R&D facilities that develop new 
formulations and perform efficacy and field testing on these new 
formulations. These facilities requested exemption from the PFPR 
effluent guidelines for several reasons. First, the majority of 
wastewater that is generated at these facilities is due to operation of 
a greenhouse or residue laboratory. EPA notes that even if these 
facilities are included in the final regulation, these wastewaters 
should not be considered process wastewater associated with pesticide 
formulating, packaging and repackaging operations.
    Second, the remainder of wastewater is generated by the operation 
of a quality control (QC) laboratory or by cleaning the pilot scale 
formulating equipment. Both of these wastewater sources would have been 
considered PFPR process wastewaters under the proposed rule. However, 
as discussed in today's notice, EPA is considering whether to exempt 
laboratory equipment rinsates from cleaning analytical equipment from 
the definition of PFPR process wastewater. In the case of rinsate 
generated from cleaning the experimental formulation equipment, 
commenters stated that they could not meet the proposed regulation of 
zero discharge based on reuse. Since these facilities do not produce 
the same pesticides again once they have completed testing, they do not 
have the same ability to reuse water as a typical PFPR facility. EPA is 
soliciting comment and additional information on whether stand alone 
R&D facilities that perform PFPR operations should be exempted from the 
PFPR effluent guidelines rule. EPA is not considering exempting 
wastewaters generated by R&D activities at PFPR facilities.
     Stand alone direct discharging PFPR facilities--EPA 
requests comment on allowing stand alone direct discharging PFPR 
facilities (i.e., PFPR facilities that do not perform pesticide 
manufacturing operations) to have the option of complying with the 
pollution prevention alternative. [Note: During the development of the 
proposed regulation, EPA estimated that there were only two direct 
discharging PFPR stand alone facilities (one of which was both an 
indirect and a direct discharger).] Based on available data, EPA does 
not believe that stand alone PFPR facilities have the necessary 
treatment in place to discharge directly to the nation's waters; 
therefore, Appendix B does not include BAT and NSPS limitations for 
PFPR stand alone direct discharging facilities.
    Triple rinse and the pollution prevention allowable discharge--EPA 
solicits comment and data on concentrations of pollutants (PAIs and 
other pollutants) found in the second and third rinses of a triple 
rinse from cleaning equipment interiors or raw material drums. In 
discussions with industry, EPA was asked whether the second or third 
rinses of a triple rinse could be considered a P2 allowable discharge 
for the purposes of the pollution prevention alternative. Under the 
pollution prevention alternative, as it is presented today, these 
rinses would have to be reused because EPA believes that these 
subsequent rinses contain pollutant loadings which are at high enough 
levels to be reused. However, if sufficient data is available, EPA may 
reconsider specifying reuse of these rinses and allow discharge 
(possibly only after treatment) in the final regulation. [Note to 
commenters providing data: please indicate if data represents 
concentrations in second or third rinses and if from drum rinsing, 
interior equipment rinsing, minibulk or bulk tank rinsing.]
    Burden to permitting authorities (NPDES and Pretreatment)--EPA 
solicits comment from POTWs and NPDES permit writers on the burden to 
them associated with both the variations of the pollution prevention 
alternative and on the different implementation approaches. EPA 
believes the burden for either of the variations of the P2 alternative 
and for implementation by self-certification is no larger than what is 
associated with the proposed zero discharge limitation as on-site 
inspections would still be the expected method of demonstrating 
compliance. EPA notes that implementation by self-certification of the 
pollution prevention alternative does not require analytical testing on 
the part of the permitting authority. However, EPA solicits comment, 
including estimates of burden, on whether there would be a substantial 
additional burden associated with increased use of guidance (versus the 
use of all practices being specified in the regulatory text). In 
addition, EPA solicits estimates of the burden associated with 
requiring submittal of paperwork for approval to the permitting 
authority (NPDES and/or pretreatment authority).

(1) After following the practices above, some wastewaters may require   
  treatment prior to discharge to POTWs. See definition of pollution    
  prevention allowable discharge.                                       
(2) After following the practices above, all wastewaters require        
  treatment prior to discharge directly to the nation's waters. See     
  definition of pollution prevention allowable discharge.               

Appendix C--List of PAI Specific Treatment Technologies

    This Appendix C contains those pollutant control technologies, such 
as hydrolysis, chemical oxidation, metals precipitation and activated 
carbon adsorption, which have been used for estimating compliance costs 
on a PAI specific basis. In general, these treatment technologies have 
been determined to be effective in treating pesticide containing 
wastewaters in literature, in bench or pilot scale treatability studies 
or in the Pesticide Manufacturing effluent guidelines.1 These are 
the same technologies that were presented as part of the Universal 
Treatment System at the time of proposal. However, these technologies 
are PAI specific and may need to be used in conjunction with one 
another to provide treatment for all PAIs used at a facility over a 
period of time. In addition, facilities may experience difficulties 
treating wastewaters that contain emulsions, therefore, ``appropriate'' 
treatment for emulsified wastewaters must include an emulsion breaking 
step. [Note: EPA has costed facilities for these types of dynamic 
treatment needs.] [[Page 30241]] 

    \1\ EPA is still determining the appropriate treatment 
technologies for a number of inorganic pesticide chemicals. 
Activated carbon (AC) adsorption was only used to provide a 
conservative cost estimate. Therefore, listed technologies for such 
PAIs are subject to change for final promulgation.

\1\ The 272 Pesticide Active Ingredients (PAIs) are listed first, by PAI code, followed by the non-272 PAIs from
  the 1988 FIFRA and TSCA Enforcement System (FATES) Database, which are listed in Shaughnessy code order. PAIs 
  that were exempted or reserved from the supplemental PFPR effluent guidelines are not listed in the table.    
\2\ The non-272 PAI names are taken directly from the 1988 FATES database. Several of the PAI names are         
  truncated because the PAI names listed in the FATES database are limited to 60 characters.                    
\3\ The non-272 PAIs do not have PAI codes.                                                                     
\4\ All Shaughnessy codes are taken from the 1988 FATES database. Some of the 272 PAIs are not listed in the    
  1988 FATES database; therefore, no Shaughnessy codes are listed for these PAIs.                               
\5\ The PAI classification and structural group are not provided for every PAI. Structural groups are provided  
  for the 272 PAIs, and classifications are provided for the non-272 PAIs.

\6\ The listed treatment technology represents the technology used as the basis for developing treatment costs  
  for wastewaters containing the PAI. The analysis of treatment technologies has not been completed for all     
  PAIs, therefore some non-272 PAIs were costed for activated carbon as a temporary treatment technology to give
  a conservatively high cost estimate.                                                                          
\7\ PAIs with an ``I'' in this column are considered to be active ingredients only when used on combination with
  other active ingredients listed in this table.                                                                
                                                                                                                
*This PAI code represents a category or group of PAIs; therefore, it has multiple Shaughnessy codes.
