I. PRELIMINARY WORK PLAN – Irgarol

Introduction

The Food Quality Protection Act of 1996 mandated the continuous review of 

existing pesticides. All pesticides distributed or sold in the United States must generally 

be registered by EPA, based on scientific data showing that they will not cause 

unreasonable risks to human health or the environment when used as directed on product 

labeling. The registration review program is intended to make sure that, as the ability to 

assess risk evolves and as policies and practices change, all registered pesticides continue 

to meet the statutory standard of no unreasonable adverse effects. Changes in science, 

public policy, and pesticide use practices will occur over time. Through the new 

registration review program, the Agency periodically reevaluates pesticides to make sure 

that as change occurs, products in the marketplace can be used safely. Information on 

this program is provided at: http://www.epa.gov/oppsrrd1/registration_review/. 

The Agency is implementing the registration review program pursuant to Section 

3(g) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and will review 

each registered pesticide every 15 years to determine whether it continues to meet the 

FIFRA standard for registration. The Agency will consider benefits information and data 

as required by FIFRA. The public phase of registration review begins when the initial 

docket is opened for each case. The docket is the Agency’s opportunity to state what it 

knows about the pesticide and what additional risk analyses and data or information it 

believes are needed to make a registration review decision. After reviewing and 

responding to comments and data received in the docket during this initial comment 

period, the Agency will develop and commit to a final work plan and schedule for the 

registration review of Irgarol. 

 Irgarol (PC Code 128996) is registered for use as an antifoulant and materials 

preservative with a variety of registered uses. It is registered for use as an antifoulant to 

boat hulls, and as a preservative in paints, caulks, coatings, sealants, grouts, vinyl roofing, 

roof coatings, cements, stucco, wood stains, adhesives, plasters, and incorporated into 

boat hulls themselves. 

 A pesticide product containing Irgarol was first registered in September 1994. No 

Reregistration Eligibility Decision (RED) has been issued for this chemical. The Agency 

anticipates needing additional data to complete a risk assessment for the Irgarol 

registration review. 

Risk Assessment Status & Anticipated Data Needs

Human Health Risk Assessment Status and Anticipated Data Needs 

The Agency has reviewed the hazard and exposure databases for Irgarol and 

anticipates that additional toxicity and exposure data will be needed for the registration 

review of this case. Based on its reviews, the Agency believes risk assessments are 

5 of 107 
Docket Number: EPA-HQ-OPP-2010-0003 

www.regulations.gov 

needed to ensure that the Irgarol registration review case meets the FIFRA and FFDCA 

standards. The Agency will complete the human health risk assessments presented 

below. 

• Residential Exposure risk assessment via application of Irgarol-preserved 

paints and coatings. 

• Occupational Exposure risk assessment via direct-pour addition of Irgarol to 

materials being preserved, construction workers/roofers/painters working with 

preserved building materials, and application of Irgarol-based antifoulants to 

boat hulls and other aquatic surfaces. 

• Dietary (Drinking Water) risk assessment should Irgarol and its degradation 

products (Table 1) leach from water-contacting surfaces or be discharged by 

facilities and pass through water treatment plants into the drinking water 

supply. 

Further information and detailed justifications for the studies expected to be 

needed are available in “Summary of Human Health Effects Data for the Irgarol 

Registration Review Decision Document”, dated ___, 2010. 

Dietary and Drinking Water Exposure and Risk

Dietary Food Exposure 

Dietary (food) exposure to Irgarol is not expected to occur. Many of the use sites 

are inherently non-food-contact such as boat bottoms, stucco, and building materials. 

Although certain treated paints, coatings, stains, and caulks could be applied to surfaces 

having food contact, such as picnic tables, crop harvesting equipment, or commodity 

shipping bins, product labels with these uses restrict their application to outdoors, and 

prohibit use that may result in contact with food, feed, livestock, dairy animals, potable 

water, or living plants. 

Dietary Drinking Water Exposure 

The registered uses of Irgarol could result in contamination of surface water and 

groundwater because the algaecide is expected to slowly leach from antifoulant-painted 

boats. Also, wastewater containing residues may be discharged from facilities 

manufacturing paints, coatings, stucco, stains, caulks, and building materials formulated 

with Irgarol. Finally, leaching of residues from outdoor surfaces covered with Irgaroltreated materials may occur. Published literature indicates that abiotic hydrolysis, 

photolysis, and microbial metabolism will occur slowly in water. There is evidence that 

the degradates (see Table 1), which are closely related to Irgarol, are persistent in the 

aquatic environment. In fact, these degradates have been detected in a number of coastal 

waterways. Therefore, there is the potential for human exposure to Irgarol residues in 

drinking water to occur. The need for a drinking water exposure assessment will be 

revisited upon submission and review of the environmental fate data the Agency 

anticipates needing. These environmental fate data would be expected to be useful to 

6 of 107 
Docket Number: EPA-HQ-OPP-2010-0003 

www.regulations.gov 

determine if Irgarol can pass through wastewater treatment facilities into drinking water 

or migrate into residential groundwater wells as a result of its current use patterns. 

Tolerances

There are no tolerances or exemptions from tolerances for Irgarol.

aquatic environments, and they have been detected in a number of coastal waterways.

Aggregate/Cumulative Exposure & Risk

 In examining aggregate exposure, EPA takes into account the available and 

reliable information concerning exposures to pesticide residues in food and drinking 

water, as well as non-occupational pesticide exposures. As dietary (food) human 

exposure is not expected to result from the currently registered Irgarol uses, aggregate 

risk is likely to consist of residential exposure and, possibly, drinking water exposure. 

However, the need for a drinking water exposure assessment (and inclusion in an 

aggregate assessment) will be determined upon submission and review of the 

environmental fate data the Agency anticipates needing. Therefore, the need for an 

aggregate assessment will be revisited upon submission and review of the environmental 

fate data and human toxicology data that are anticipated as being required. 

 Section 408(b)(2)(D)(v) of FFDCA requires that, when considering whether to 

establish, modify, or revoke a tolerance, the Agency consider “available information” 

concerning the cumulative effects of a particular pesticide's residues and “other 

substances that have a common mechanism of toxicity.” EPA has not yet determined 

whether Irgarol has a common mechanism with other triazines; consequently, a 

cumulative assessment will not be performed at this time. 

Occupational and Residential Exposure and Risk

 The Agency reviewed all available data associated with Irgarol and has determined 

that the currently registered uses of Irgarol may result in residential and occupational 

exposure. Therefore, the Agency will conduct residential (handler and post-application) 

and occupational (handler) risk assessments to assess possible dermal and inhalation 

exposure to Irgarol. 

Anticipated Human Health Data Needs Summary:

 The Agency anticipates needing the following toxicity and exposure studies to 

perform a complete human health risk assessment for Irgarol: 

Anticipated Toxicity Data Needs 

• (GLN 870.3465) 90-day rat inhalation toxicity 

Occupational Handler Exposure Data Needs 

• (GLN 875.1700) Product Use Information – Outdoor 

• (GLN 875.2700) Product Use Information – Indoor

Further information and detailed justifications for the studies expected to be 

needed are available in “Summary of Human Health Effects Data for the Irgarol 

Registration Review Decision Document,” dated ___, 2010. 

Anticipated Physical/ Chemical Property Data Needs 

 All product chemistry data requirements have been fulfilled for the active 

ingredient Irgarol. Therefore, the Agency does not anticipate needing additional product 

chemistry data at this time. 

Further information is available in “Summary of Product Chemistry, Environmental 

Fate, and Ecotoxicity Data for the Irgarol Registration Review Summary Document”, 

dated ___, 2010. 

Anticipated Environmental Fate and Ecotoxicity Risk Assessment and Data Needs 

The Agency has reviewed the environmental fate and ecological hazard databases for 

Irgarol. Based on its review, EPA believes risk assessments are needed to ensure that the 

Irgarol registration review case meets the FIFRA standards. The Agency will complete 

the environmental fate and ecological hazard risk assessments presented below. Further 

information and detailed justifications for the studies that are expected to be required are 

available in the document titled “Summary of Product Chemistry, Environmental Fate, 

and Ecotoxicity Data for the Irgarol Registration Review Decision Document,” dated 

___, 2010. 

• Environmental fate, ecological and endangered species assessments for 

outdoor use of Irgarol-preserved materials such as exterior paints, coatings, and 

building materials that potentially pass through waste water treatment plants 

(WWTPs) and may be discharged into terrestrial and aquatic environments. 

Outdoor Irgarol use as wood preservatives and antifouling coatings will also be 

examined.

Environmental fate and ecological risk assessments have not been conducted for 

Irgarol. The use of Irgarol as a materials preservative could potentially result in 

environmental exposure. These uses may result in waste water treatment plant (WWTP) 

discharges into terrestrial and aquatic environments. Therefore, the Agency will conduct 

environmental fate and ecological risk assessments to assess environmental exposure 

resulting from possible discharges into terrestrial and aquatic environments. The Agency 

also anticipates that environmental fate and ecological data will be needed to conduct 

these assessments.

• (GLN 850.4450) Aquatic Plants Field Study 

Endangered Species 

 The Agency has not conducted a risk assessment that supports a complete 

endangered species determination. The ecological risk assessment planned during 

registration review will allow the Agency to determine whether Irgarol use has “no 

effect” or “may affect” federally listed threatened or endangered species (listed species) 

or their designated critical habitats. When an assessment concludes that a pesticide’s use 

“may affect” a listed species or its designated critical habitat, the Agency will consult 

10 of 107 
Docket Number: EPA-HQ-OPP-2010-0003 

www.regulations.gov 

with the U.S. Fish and Wildlife Service and/or National Marine Fisheries Services (the 

Services), as appropriate.

Trade Irritants 

Through the registration review process, the Agency intends to solicit information 

on trade irritants and, to the extent feasible, take steps toward facilitating irritant 

resolution. Growers and other stakeholders are asked to comment on any trade irritant 

issues resulting from lack of Maximum Residue Limits (MRLs) or disparities between 

U.S. tolerances and MRLs in key export markets, providing as much specificity as 

possible regarding the nature of the concern. 

Water Quality 

Irgarol is not identified as a cause of impairment for any water bodies listed as 

impaired under section 303(d) of the Clean Water Act, based on information provided at 

http://iaspub.epa.gov/tmdl_waters10/attains_nation_cy.cause_detail_303d?p_cause_grou

p_id=885. In addition, no Total Maximum Daily Loads (TMDL) have been developed 

for Irgarol, based on information provided at 

http://iaspub.epa.gov/tmdl_waters10/attains_nation.tmdl_pollutant_detail?p_pollutant_gr

oup_id=885&p_pollutant_group_name=PESTICIDES. More information on impaired 

water bodies and TMDLs can be found at http://www.epa.gov/owow/tmdl/. The Agency 

invites submission of water quality data for this pesticide. To the extent possible, data 

should conform to the quality standards in Appendix A of the OPP Standard Operating 

Procedure: Inclusion of Impaired Water Body and Other Water Quality Data in OPP’s 

Registration Review Risk Assessment and Management Process (see: 

http://www.epa.gov/oppsrrd1/registration_review/water_quality_sop.htm), in order to 

ensure they can be used quantitatively or qualitatively in pesticide risk assessments.

Environmental Justice 

EPA seeks to achieve environmental justice, the fair treatment and meaningful 

involvement of all people, regardless of race, color, national origin, or income, in the 

development, implementation, and enforcement of environmental laws, regulations, and 

policies. To help address potential environmental justice issues, the Agency seeks 

information on any groups or segments of the population who, as a result of their 

location, cultural practices, or other factors, may have atypical, unusually high exposure 

to Irgarol, compared to the general population. Please comment if you are aware of any 

sub-populations that may have atypical, unusually high exposure compared to the general 

population. 

Structure Activity Relationships 

EPA must rely upon information of appropriate quality and reliability for each 

decision made by the Agency. In the Office of Pesticide Programs (OPP), the evaluation 

process for a pesticide chemical traditionally begins with the applicant’s submission of a 

set of studies conducted with the specific pesticide chemical of interest. The use of the 

results of such testing (measured data) is a logical, scientifically rigorous process that 

identifies the physical, chemical, and environmental fate properties of the pesticide, as 

12 of 107 
Docket Number: EPA-HQ-OPP-2010-0003 

www.regulations.gov 

well as the dose and endpoints at which an adverse effect can occur in various animal 

species. 

Today, there is significant interest in alternative techniques, i.e., techniques other 

than data generation that could significantly inform the Agency’s decision-making 

process. Recently, OPP has made increasing use of structure activity relationship (SAR) 

as part of its regulatory decision-making process. In the SAR process, a chemical's 

molecular structure is compared to that of other chemicals for which data are available. 

These structural similarities are then used to make predictive judgments about a 

chemical’s physical, chemical, and biological properties. Thus, the chemical’s physical, 

chemical, and biological properties are a function of (or directly related to) the chemical’s 

molecular structure. Quantitative SAR is referred to as QSAR. To develop a QSAR, a 

selected set of measured data on a single physical, chemical, or biological property is 

used to derive a model (an equation) to predict the value of that property. 

 Since SAR assessments and QSAR modeling are another set of tools that are 

available to Agency scientists, OPP has begun a process shift that envisions shifting from 

the current study-by-study approach to an approach in which the use of predicted data, 

generated using validated models, is considered along with information from open 

literature and studies specifically generated under Part 161 requirements. All relevant 

information would be considered as part of a weight-of-the-evidence evaluation. 

At this time, EPA believes that for certain endpoints, especially physical/chemical 

and fate properties, that SAR and QSAR might be effectively utilized to fulfill these data 

requirements for many antimicrobial pesticide chemicals. When considering biological 

properties, at this time, EPA believes that SAR and QSAR can be most effectively 

utilized in the evaluation of chemicals that exhibit lower toxicity for human health and/or 

ecotoxicity parameters. This is appropriate because the risk assessment for lower toxicity 

chemicals can be stream-lined, i.e., a screening-level assessment procedure rather than 

multiple tiers of assessments with progressively more data requirements. 

If stakeholders believe that submission of predicted data can fulfill one of the data 

needs for Irgarol, then the Agency invites submission of this information. The submitter 

would be expected to supply a rationale describing the utility of the information and 

provide documentation on the scientific validity of the information. The determination 

that the predicted data fulfills the data requirement would be at the sole discretion of the 

Agency. Pre-submission consultation with the Agency is encouraged. 

Endocrine Disruptor Screening Program 

 Irgarol is a member of a class of pesticides collectively referred to as “triazine” 

pesticides. The Agency has examined the triazine class of pesticides with respect to a 

potential common mechanism of toxicity. This examination may be found at 

http://www.epa.gov/oppsrrd1/REDs/triazine_cumulative_risk.pdf. Several members of 

this class have been identified as causing toxicity through a similar mechanism of action. 

Specifically, atrazine, simazine, propazine, and certain degradates are considered to act 

13 of 107 
Docket Number: EPA-HQ-OPP-2010-0003 

www.regulations.gov 

through disruption of the hypothalamic-pituitary-gonadal axis to attenuate the luteinizing 

hormone surge. As a result of this attenuation, exposure of the animal to estrogen is 

continuous, providing an environment conducive to the development of mammary gland 

tumors. 

 In the case of Irgarol, structural similarity exists with at least one member of the 

triazine class, namely Terbutryn. However, there are no mechanistic data specific to 

Irgarol that have been generated to determine if it shares a common mechanism of 

toxicity with Terbutryn. Pharmaco-kinetic data for Irgarol have also not been generated 

to permit comparison with those of other structurally-similar triazine pesticides. Without 

additional data such as the above, neither can it be determined whether Irgarol shares a 

common mechanism of toxicity with other triazine pesticides nor can it be completely 

ruled out. The Agency would like more data on these concerns, but as there is already a 

data call-in program designed specifically for endocrine data needs, described below, the 

Agency does not anticipate that it will request endocrine-related data for Irgarol for 

Registration Review. However, if studies are received in response to an Endocrine 

Disruptor Screening Program data call-in before or during the Registration Review risk 

assessment for Irgarol, such data may be considered as part of the risk assessment. 

As required under FFDCA section 408(p), EPA has developed the Endocrine 

Disruptor Screening Program (EDSP) to determine whether certain substances (including 

pesticide active and other ingredients) may have an effect in humans or wildlife similar to 

an effect produced by a “naturally occurring estrogen, or other such endocrine effects as 

the Administrator may designate.” The EDSP employs a two-tiered approach to making 

the statutorily required determinations. Tier 1 consists of a battery of 11 screening assays 

to identify the potential of a chemical substance to interact with the estrogen, androgen, 

or thyroid (E, A, or T) hormonal systems. Chemicals that go through Tier 1 screening 

and are found to have the potential to interact with E, A, or T hormonal systems will 

proceed to the next stage of the EDSP where EPA will determine which, if any, of the 

Tier 2 tests are necessary based on the available data. Tier 2 testing is designed to 

identify any adverse endocrine related effects caused by the substance, and establish a 

dose-response relationship between the dose and the E, A, or T effect. 

Between October 2009 and February 2010, EPA issued test orders/data call-ins 

for the first group of 67 chemicals, which contains 58 pesticide active ingredients and 9 

inert ingredients. This list of chemicals was selected based on the potential for human 

exposure through pathways such as food and water, residential activity, and certain postapplication agricultural scenarios. This list should not be construed as a list of known or 

likely endocrine disruptors. 

Irgarol is not among the group of 58 pesticide active ingredients on the initial list 

to be screened under the EDSP. Under FFDCA sec. 408(p) the Agency must screen all 

pesticide chemicals. Accordingly, EPA anticipates issuing future EDSP test orders/data 

call-ins for all pesticide active ingredients.

Recent Regulatory Actions

There have been no recent regulatory actions involving Irgarol. 

Human Health Risk Assessment Status

The Agency has reviewed the hazard and exposure databases for the Irgarol 

registration review case and anticipates that additional toxicity and exposure studies will 

be needed for registration review. The Agency will conduct toxicological and 

occupational risk assessments to ensure that the Irgarol registration review case meets the 

safety standards established by FIFRA and FFDCA, as amended by FQPA. The need for 

a dietary (drinking water) risk assessment will be revisited upon receipt and review of the 

environmental fate data that are anticipated as being needed. 

 Further information and detailed justifications for the studies that are expected 

to be needed are available in “Summary of Human Health Effects Data for the Irgarol 

Registration Review Decision Document”, dated ___, 2010. 

Product Chemistry Database Status

The Agency has reviewed the product chemistry database for the Irgarol 

registration review case and anticipates that no additional product chemistry data will be 

needed for registration review. 

Further information is available in “Summary of Product Chemistry, 

Environmental Fate, and Ecotoxicity Data for the Irgarol Registration Review Summary 

Document”, dated ___, 2010. 

Environmental Fate & Ecological Risk Assessment Status

 The Agency has reviewed the environmental fate and ecotoxicity databases for 

the Irgarol case and anticipates that additional environmental fate and ecotoxicity data 

will be needed for registration review. The Agency will conduct environmental fate, 

ecotoxicity, and endangered species risk assessments for Irgarol. 

The Agency has not conducted a risk assessment that supports a complete 

endangered species determination. The ecological risk assessment planned during 

registration review will allow the Agency to determine whether Irgarol use has “no 

effect” or “may affect” federally listed threatened or endangered species (listed species) 

or their designated critical habitats. When an assessment concludes that a pesticide’s use 

“may affect” a listed species or its designated critical habitat, the Agency will consult

with the U.S. Fish and Wildlife Service and/or National Marine Fisheries Services (the 

Services), as appropriate.
