On June 3, 2020, the U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit) issued an opinion in National Family Farm Coalition v. EPA, No. 19-70115, vacating the U.S. Environmental Protection Agency’s (EPA) 2018 decisions to extend the conditional registrations for three reduced volatility dicamba herbicides, Bayer’s XtendiMax, Corteva’s FeXapan, and BASF’s Engenia.
The manufacturers of these dicamba products designed them to facilitate control of glyphosate resistant weeds in strains of soybeans and cotton that have been genetically modified to be dicamba tolerant (DT). Although the manufacturers intended these dicamba products to be less volatile and less susceptible to drift into adjacent non-target areas than previous formulations of dicamba, there were nonetheless many complaints that the products cause damage to non-tolerant crops and other vulnerable vegetation. The Petitioners that challenged EPA’s decision to extend the conditional registrations for these reformulated dicamba products include a group representing small farmers who claim that the new dicamba products have damaged their crops (National Family Farm Coalition) and several non-governmental organizations that routinely oppose new pesticide registrations (the Center for Food Safety, the Center for Biological Diversity, and Pesticide Action Network North America).
Although the case included some allegations by the Petitioners that EPA did not comply with the requirements of the Endangered Species Act, the court did not reach those issues. The court found unanimously that EPA’s decision to extend the conditional registrations for the three dicamba herbicides did not satisfy the requirements of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Specifically, the court found that the administrative record compiled by EPA did not include “substantial evidence” supporting EPA’s determination that registering the new uses “would not significantly increase the risk of any unreasonable adverse effects on the environment.” EPA is required under FIFRA Section 3(c)(7)(B) to make this determination to grant a conditional registration of new uses of a currently registered pesticide. The court concluded that EPA could not make this required determination because, the court stated, the record shows that EPA “substantially understated the risks that it acknowledged” and also “entirely failed to acknowledge other risks.”
According to the court, EPA made six material errors in its analysis supporting the registrations. First, the court stated that EPA understated the amount of acreage planted with DT crops in 2018, and consequently also underestimated the amount of the new dicamba products that would be applied that year, even though the decision to extend the conditional registrations for the new dicamba products was not issued until the end of the 2018 growing season. Second, in the court’s view, EPA improperly found that the number of complaints concerning damage to non-target crops and vegetation by the new dicamba products might be over-reported when the record included overwhelming evidence that non-target damage was being under-reported. Third, the court stated that EPA refused even to estimate how much damage to non-target vegetation would be caused by the new dicamba products when the record contained sufficient information for EPA to make such an estimate. Fourth, according to the court, EPA refused to acknowledge the substantial risk of non-compliance with the large number of detailed restrictions set forth in the 40-page approved label, although the court found that “there was substantial evidence that even conscientious applicators had not been able to consistently adhere to the label requirements.” Fifth, the court believes EPA failed to acknowledge the anti-competitive effect of the new technology, which encourages other growers to use DT crops even if they do not use the new dicamba products, to avoid damage from nearby applications. Sixth, according to the court, EPA failed to acknowledge the social cost being caused in small communities where damage caused by use of the new dicamba products has turned formerly amicable neighbors against each other.
Based on all of these purported deficiencies, the court held that EPA’s rationale for determining that the risk of unreasonable adverse effects would not be significantly increased by the new dicamba uses, and that the registration for the new dicamba products could therefore be extended for two additional years, was not supported by “substantial evidence” in the administrative record taken as a whole. The court also held that remanding the matter to EPA for further action without vacatur would not be appropriate because EPA did not satisfy the requirement to extend the conditional registrations. Instead, the court simply vacated the registrations and invited EPA to try again. The court acknowledged that such a decision would cause disruption, especially for those growers that have already purchased DT seeds and dicamba herbicides for this year's growing season, but concluded that no remedy other than vacatur would be appropriate given the deficiencies in the administrative record.
When FIFRA was amended to allow new pesticide products to be “conditionally” registered even though the applicants had not submitted data to satisfy all applicable requirements, the focus was primarily on allowing registration of new products that are “substantially similar” to already registered products. FIFRA Section 3(c)(7) also allows conditional registrations to be issued for new uses of existing active ingredients and for new active ingredients without all required data if EPA has sufficient information to make certain findings while it waits for additional data, but requires that EPA be able to determine that certain requirements can be met even though not all of the supporting data that will ultimately be needed are yet available.
This court’s decision illustrates the type of problems that can occur when EPA issues a conditional registration for new products that are not “substantially similar” to registered products. The court’s view of the sufficiency of the record in this case sets a high bar for the determinations that must support other types of conditional registrations. This problem was previously illustrated when a reviewing court vacated a new registration for a new nanosilver product even though there were already registered nanosilver products. In that case, because EPA chose as a matter of policy to characterize the product as a new active ingredient, it was required to make a “public interest” determination under FIFRA Section 3(c)(7)(C). When the administrative record was deemed insufficient to support this mandatory determination, the reviewing court vacated the registration.
In the case of the new dicamba products, to grant conditional registrations for new uses of an existing active ingredient, EPA was required to determine that the new uses on DT soybeans and cotton would not “significantly increase the risk of unreasonable adverse effects on the environment” under FIFRA Section 3(c)(7)(B). The court found the record supporting this mandatory determination to be insufficient, resulting in the court’s vacatur of EPA’s decision. These two reviewing courts have taken a relatively deep dive into the administrative record supporting a conditional registration for a new use of an existing active ingredient or a new active ingredient in evaluating whether substantial evidence in the record supports the determinations required by FIFRA. Whether future decisions will maintain such a stringent evidentiary standard will be important to monitor.

On April 23, 2020, the Supreme Court ruled that pollution traveling indirectly to rivers and streams through groundwater can be covered by the Clean Water Act’s (CWA) permitting requirements. The case, County of Maui, Hawaii v. Hawaii Wildlife Fund, et al, 590 U.S. (2020), concerned whether pollutants discharged from a point source into groundwater, a non-point source, and then conveyed into navigable waters fall within permitting requirements of the CWA. In a 6-3 Opinion delivered by Justice Breyer, the Court held that the CWA “requires a permit when there is a direct discharge from a point source into navigable waters or when there is the functional equivalent of a direct discharge.” Slip op. at 15.
Under the CWA, a point source is a discernable conveyance such as a pipeline and other conduit, including wells (the Court notes that wells ordinarily result in discharge of pollutants through groundwater). Slip op. at 13. The case at issue concerned the County of Maui’s (Maui) operation of a wastewater reclamation facility that collected and partially treated sewage before pumping the treated water into four underground injection wells. From the wells, the treated water traveled half a mile through groundwater into the Pacific Ocean, a navigable water. Maui had not obtained a permit for the discharge, and in 2012, several environmental groups brought a citizens’ CWA lawsuit against the county.
The legal question of whether the CWA’s permitting program covers pollution that travels from a point source, like a factory discharge pipe or a containment pond, through groundwater before reaching a downstream water has major implications for industries ranging from agriculture to oil and gas. The Court’s “functional equivalent” standard for the reach of federal regulation is an interpretation that is narrower than the one sought by environmentalists and endorsed by the Ninth U.S. Circuit Court of Appeals, but the Court declined to defer to the U.S. Environmental Protection Agency’s (EPA) 2019 Interpretative Statement. 84 Fed. Reg. 16810, 16824 (April 2019).
EPA’s Interpretive Statement supported the argument of Maui and the U.S. Solicitor General that if any non-point source lies between the point source and the navigable water, a permit is not required for the release. Groundwater and non-point pollution that is generated, for instance, by rainwater runoff is not covered by the CWA and is regulated by the states. The Court rejected this interpretation, posing the question: “If that is the correct interpretation of the statute, then why could not the pipe’s owner, seeking to avoid the permit requirement, simply move the pipe back, perhaps only a few yards, so that the pollution must travel through at least some groundwater before reaching the sea?” Slip op. at 10. The Court held that “to follow EPA’s reading would open a loophole allowing easy evasion of the statutory provision’s basic purposes. Such an interpretation is neither persuasive nor reasonable.” Slip op. at 12.
The Court did not adopt the “fairly traceable” standard supported by the environmental groups and the Ninth Circuit either, as its scope would be too broad, and would interfere too seriously with states’ traditional and intended regulatory authority over groundwater and non-source pollution. Slip op. at 7-8.
The “functional equivalent of a direct discharge” standard will require a permit for discharge from any point source directly into navigable waters, and from point sources when the discharge “reaches the same result through roughly similar means.” The Court identified seven factors that may be relevant in determining whether the discharge comes “from” a point source:
(1) transit time, (2) distance traveled, (3) the nature of the material through which the pollutant travels, (4) the extent to which the pollutant is diluted or chemically changed as it travels, (5) the amount of pollutant entering the navigable waters relative to the amount of the pollutant that leaves the point source, (6) the manner by or area in which the pollutant enters the navigable waters, (7) the degree to which the pollution (at that point) has maintained its specific identity. Slip op. at 16.
The Court notes that time and distance will be important factors in many (though potentially not all) cases. For example, a distance of a few feet is concretely within the scope of the permitting requirement; a distance of 50 miles that may take a year for the water and perhaps mixing with other materials before reaching the navigable water is indeterminate.
The Court stated that the “functional equivalent” standard will essentially maintain EPA’s longstanding interpretation of the 1972 water law’s requirements prior to the 2019 Interpretive Statement that sought to narrow its reach. The Court further acknowledges that the new standard may expand the scope of the CWA as it applies to wells and septic systems, but does not expect an “unmanageable expansion” of the permitting program, and expects that EPA and the states will mitigate harms and initiate a best practices permitting policy, and that judges will exercise discretion mindful of the complexities of indirect discharges. Slip op. at 18.
The decision of the Supreme Court to construe National Pollutant Discharge Elimination System permitting requirements to extend to indirect discharges that originate at a point source but travel through groundwater before reaching navigable waters was not particularly surprising. Reviewing courts have generally been mindful that completely excluding all discharges to groundwater from permitting might encourage dischargers to use discharges to groundwater to evade otherwise applicable control requirements. Nonetheless, it was somewhat surprising when the Court created a new “functional equivalence” standard that was not specifically advocated by the litigants.
Although the Court clearly intended to adopt a construction that was less expansive than the “fairly traceable” standard adopted by the Ninth Circuit, EPA and the states will have to determine how the seven potentially relevant factors identified by the Court will be utilized in determining when a permit will be required for indirect discharges. EPA and the states will also have discretion to determine whether there are other “potentially relevant factors applicable to factually different cases” as anticipated by the Court. Slip op. at 16. This case involved deliberate discharges of municipal wastewater to underground injection wells, but future policy disputes and litigation are likely to focus on indirect discharges that are more inadvertent in character. Activities of particular interest include indirect discharges from agriculture, and indirect discharges from impoundments that have been used to collect coal ash, mining tailings, and other types of industrial waste.
In the absence of Congressional intervention to codify clearly what is required, the courts can only do so much. The Supreme Court has concluded that Congress could not have intended to create a loophole in the water permitting scheme so large as to encourage deliberate evasion, but it falls now to EPA and the states to determine what sort of indirect discharges are “functionally equivalent” to a direct discharge. Although the Court has afforded considerable latitude to permitting agencies in deciding how to effectuate the new standard, the decision will most likely lead to a new round of contentious litigation before a policy for permitting of indirect discharges can ultimately be adopted.

On April 6, 2020, the U.S. Environmental Protection Agency (EPA) published a notice in the Federal Register announcing the availability of its progress report in meeting its performance measures and goals for pesticide reregistration during fiscal year 2017 (2017 Report). Section 4(l) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) requires EPA to publish information about EPA’s annual achievements in this area. The 2017 Report discusses the completion of tolerance reassessment and describe the status of various regulatory activities associated with reregistration. The 2017 Report also provides the total number of products reregistered and products registered under the “fast-track” provisions of FIFRA. The report is available at EPA-HQ-OPP-2014-0125. Comments can be submitted on or before June 5, 2020.
EPA’s completed product registration actions totaled 255, short of EPA’s goal of 600 actions. The table below details the actions completed in FY 2017.
Table 1.—Product Reregistration Actions Completed in FY 2017 (as of September 30, 2017)
|Product reregistration actions
|Product amendment actions
|Product cancellation actions
|Product suspension actions
EPA also states that there were 4,370 products had product reregistration decisions pending at the end of FY 2017, compared to 4,621 products with product reregistration decisions pending at the end of FY 2016, and 5,133 products with product reregistration decisions pending at the end of FY 2015. Regarding changes in the universe of products in product reregistration, EPA states: “an increase or decrease can be due to fluctuations in numbers of products associated with product-specific Data Call-Ins (PDCIs).”
The number of applications for registration requiring expedited processing (i.e., “fast track” applications) that EPA considered and approved has been more consistent in recent years, with 2,223, 2,422, and 2,574 in 2015, 2016, and 2017 respectively.

On February 12, 2020, the U.S. Environmental Protection Agency (EPA) announced the availability of 11 products that have been approved for use to disinfect surfaces against the emerging multidrug-resistant fungus Candida auris (C. auris). C. auris can cause severe infections and spreads easily among hospitalized patients and nursing home residents. The 11 products are approved for use against C. auris to disinfect surfaces in hospitals, nursing homes, and other healthcare facilities, to help reduce patient infections. There were no antimicrobial pesticide products registered specifically for use against C. auris prior these new use registrations.
EPA worked in collaboration with the Centers for Disease Control and Prevention (CDC) and other federal partners to ensure that the products would be effective against C. auris. Previously, on October 16, 2019, EPA had granted public health exemptions under the provisions of section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) as amended, to the CDC, for uses of antimicrobial products, on hard, nonporous surfaces in healthcare settings for disinfection from C. auris.
The 11 products that are now registered for use against C. auris are:
- Avert Sporicidal Disinfectant Cleaner (EPA Reg. No. 70627-72);
- Blondie (EPA Reg. No. 67619-24);
- Dagwood (EPA Reg. No. 67619-25);
- Micro-Kill Bleach Germicidal Bleach Wipes (EPA Reg. No. 37549-1);
- Oxivir 1 (EPA Reg. No. 70627-74);
- Oxivir 1 Wipes (EPA Reg. No. 70627-77);
- Oxivir Wipes (EPA Reg. No. 70627-60);
- Oxycide™ Daily Disinfectant Cleaner (EPA Reg. No. 1677-237);
- Virasept (EPA Reg. No. 1677-226);
- Wonder Woman Formula B Germicidal Wipes (EPA Reg. No. 9480-12); and
- Wonder Woman Formula B Spray (EPA Reg. No. 9480-10).
Because there are few products with C. auris claims at this time, CDC and EPA have identified additional products that are effective against C. auris. Although these products do not yet have formal EPA-registered claims for C. auris, testing at CDC has confirmed they are effective against C. auris. The label on the product will not include instructions for C. auris. CDC guidance states to “follow the instructions provided for C. albicans, if included, or else follow those for fungicidal activity.” These products include:
- Oxivir TB Spray (EPA Reg. No. 70627-56); and
- PDI Super Sani-Cloth (EPA Reg. No. 9480-4).
The CDC Guidance further states that, if none of the above-listed products are available, or any of the EPA-registered products that are newly approved for the specific claims against C. auris, CDC recommends use of an EPA-registered hospital-grade disinfectant effective against Clostridioides difficile spores, because CDC believes these products have been used effectively against C. auris (List K).
Additional information on C. auris is available on EPA’s website and CDC’s website.

On February 6, 2020, Corteva Agriscience (Corteva), announced it will discontinue all production of the organophosphate (OP) insecticide chlorpyrifos by the end of the year. Corteva and its corporate predecessor, Dow AgroSciences, have been the principal global manufacturers of chlorpyrifos. Corteva announced that its decision to stop selling chlorpyrifos was based entirely on financial considerations. This announcement came on the same day that Corteva had previously agreed it would end further sales of chlorpyrifos in California, and less than a week after the date the European Union (EU) ended all sales of chlorpyrifos in member states. These actions followed a number of prior actions taken by other national and state governments to ban or severely restrict chlorpyrifos. Corteva emphasized in its public statements that the science demonstrates that chlorpyrifos can be safely used, but that the company made a business decision based on the declining markets for the product. In an interview reported by the Washington Post, Susanne Wasson, Corteva's President for Crop Protection said, “It’s a tough decision for us to make, but we don’t feel like it’s viable going forward.” In other statements, Corteva noted that in the last ten years their share of the global chlorpyrifos market had declined from 75% to less than 20%.
Chlorpyrifos has been registered for use in the U.S. for over 50 years, but has become increasingly controversial in the dozen years since the Pesticide Action Network of North America and the Natural Resources Defense Council filed a petition in 2007 to cancel all registrations and revoke all tolerances for chlorpyrifos. Following a protracted court battle and a decision by the Ninth Circuit Court of Appeals to force the U.S. Environmental Protection Agency (EPA) to take final administrative action concerning the 2007 petition, EPA proposed near the end of the Obama Administration to revoke all existing tolerances for chlorpyrifos. A significant basis for this proposal was a controversial decision by a panel of EPA scientists that the default tenfold safety factor established by the Food Quality Protection Act (FQPA) for infants and children, which EPA had previously waived based on studies establishing a threshold for acetylcholinesterase (AChE) inhibition, should be reinstated.
The new EPA safety factor determination was based in large measure on epidemiology studies that reported an association between exposure to chlorpyrifos at levels below the presumed threshold for AChE inhibition and adverse neurodevelopmental effects in children. Many industry scientists disputed the scientific basis for this EPA determination because confounding exposures and methodological biases in the epidemiology studies may have influenced the reported association with neurodevelopmental effects and because the EPA determination made unprecedented use of epidemiology data. Beyond the effect on chlorpyrifos, the EPA decision will likely continue to be controversial because EPA included a similar safety factor determination for all OP pesticides, even though the mechanism responsible for the reported neurodevelopmental effects attributed to chlorpyrifos has not been identified and the other OP products were not studied in the epidemiology studies.
In the first year of the Trump Administration, EPA Administrator Scott Pruitt decided not to adopt EPA’s previously proposed tolerance revocation and instead to deny formally the 2007 petition, citing unresolved scientific issues. This reversal of course, however, was not accompanied by any new scientific assessment or by any explicit revision of the prior FQPA safety factor determination. Later, the California Department of Pesticide Regulation (DPR) decided to designate chlorpyrifos as a Toxic Air Contaminant, a decision that was noteworthy because it was based primarily on new toxicology studies that DPR stated reported neurodevelopmental effects well below the threshold for AChE inhibition. DPR deemphasized the epidemiology data relied on in the EPA safety factor determination in its decision. Although EPA later stated that it would address these new toxicology studies as part of an accelerated registration review process, there were intervening decisions by the EU and by California to ban new sales, which may have contributed to Corteva’s February 6, 2020, decision to cease chlorpyrifos production.
The decision by Corteva to cease manufacturing chlorpyrifos reminds us that the decision to continue marketing any chemical substance cannot be based solely on the scientific data, but must also consider the regulatory climate and the economic viability of the product. For those of us with a long memory, the decision by Corteva is reminiscent of the decision nearly 40 years ago by the Dow Chemical Company to pull the plug on 2,4,5-T and silvex, after Dow had expended millions of dollars and many years of effort to contest an emergency suspension and subsequent cancellation of these herbicides. Dow made this decision even though it believed that the available data demonstrated the safety of those products.

The U.S. Environmental Protection Agency (EPA) announced on February 12, 2020, that it is seeking public input on a proposal to incorporate a new nanosilver pesticide product into textiles to combat odors, discoloration, and other signs of wear. The proposed registration decision is for NSPW Nanosilver, and the proposed pesticide product, Polyguard-NSPW Master Batch (Polyguard), will be incorporated into textiles to suppress bacteria, algae, fungus, mold, and mildew, which cause odors, discoloration, stains, and deterioration. According to EPA, based on its human health and ecological risk assessment, it has preliminarily determined that the new active ingredient in Polyguard meets the regulatory standard under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) for use as a materials preservative in textiles. EPA invites public comment on its proposal and preliminary findings. Comments are due March 13, 2020. More information is available in Docket ID EPA-HQ-OPP-2020-0043.
EPA notes that NSPW Nanosilver was the active ingredient in a previous conditional registration that it granted in 2015, for use as a materials preservative in textiles and plastics. As reported in our May 31, 2017, memorandum, that decision was challenged, and the U.S. Court of Appeals for the Ninth Circuit “vacated it on grounds that EPA’s public interest finding for granting the registration was without support in the record.” EPA states that the currently proposed product “is solely for use in specified textiles; therefore, Polyguard will have a more limited use authorization than the previously vacated conditional registration.” EPA notes that Polyguard will be formulated as a master batch, meaning that NSPW Nanosilver would be embedded within plastic beads or pellets, in contrast to the previous product registration, which was in the form of a liquid suspension.

On February 3, 2020, the U.S. Environmental Protection Agency (EPA) issued a Federal Register notice announcing the availability of an interim registration review decision for glyphosate. EPA previously issued a proposed interim registration review decision (PID) for glyphosate for comment in April 2019. At the time EPA issued the glyphosate PID for comment, EPA also issued a draft human health risk assessment and a preliminary ecological risk assessment for glyphosate. After reviewing the comments received concerning these assessments, EPA has not made any revisions to either assessment. EPA has determined that there are no dietary, residential, bystander, or occupational human health risks of concern associated with glyphosate use. EPA has also determined that there are some potential risks to plants, birds, mammals, and invertebrates from glyphosate use, but that these can be appropriately mitigated by label changes requiring enforceable spray drift management measures and adding a warning concerning the potential hazards to non-target organisms. EPA also has proposed some new measures to manage the development and spread of herbicide-resistant weeds. EPA has generally retained the proposed labeling changes identified in the PID, except for some modest adjustments to the proposed language concerning droplet size restrictions and swath displacement restrictions for aerial applications, and removal of spray drift advisory language for airblast application.
Despite considerable publicity recently concerning purported carcinogenic risks for glyphosate, including allegations that human exposure to glyphosate can be linked to non-Hodgkin's lymphoma, EPA has determined that glyphosate is not likely to be a human carcinogen and has steadfastly adhered to this basic conclusion. EPA made this determination for glyphosate after convening a meeting of the FIFRA Scientific Advisory Panel (SAP) to evaluate the carcinogenic potential of glyphosate in 2016.
The general purposes of the PID process are to allow EPA to move forward with aspects of the registration review process that are essentially complete, and to adopt interim risk mitigation measures, even though some of the actions required prior to a final registration review decision are not yet complete. As in the case of most recent PIDs, EPA states that it has not yet made a complete determination concerning potential effects or any required consultation for glyphosate under the Endangered Species Act (ESA), nor has it made a determination for glyphosate under the Endocrine Disruptor Screening Program (EDSP). In addition, EPA is considering a pending petition to prohibit preharvest use of glyphosate on oats, and to reduce the tolerance for glyphosate in oats, that was filed in 2018 by the Environmental Working Group and others. This petition is predicated on the potential carcinogenicity of glyphosate. Finally, EPA is still evaluating the question of whether additional data will be needed to evaluate properly the potential effects of glyphosate use on pollinators.
More information on glyphosate and EPA’s interim registration review decision is available here.
EPA's interim registration review decision for glyphosate is predicated on EPA's prior determination that the best available scientific data do not substantiate the claims that glyphosate may be a human carcinogen. As discussed above, the potential carcinogenicity of glyphosate was thoroughly evaluated by the FIFRA SAP in 2016. EPA's determination after that review that glyphosate is not a carcinogen has also been supported by other pesticide regulatory authorities. Nonetheless, EPA's view conflicts with a cancer classification decision for glyphosate by the World Health Organization (WHO), and with some recent tort case decisions that were based on the premise that there is a credible linkage between glyphosate exposure and human cancer. EPA recently announced that it would not permit or approve any cancer warning statements for inclusion in glyphosate labeling (including any statements that may be required pursuant to California's Prop 65) because EPA believes that such statements are false or misleading and would therefore cause the pesticides to be "misbranded."
It appears probable there will be continued litigation based on the purported carcinogenicity of glyphosate, along with various proposals to ban or restrict glyphosate use. The pending petition to restrict use of glyphosate on oats that was filed by EWG, et al., is expressly predicated on the potential carcinogenicity of glyphosate, so it appears probable that this petition will ultimately be denied by EPA. Nonetheless, unless WHO decides to reverse or modify its classification determination, or the courts determine that the recent tort awards for glyphosate users cannot be scientifically substantiated, the battles over the claimed carcinogenicity of glyphosate may persist for years.

The March 1, 2020, deadline for all establishments, foreign and domestic, that produce pesticides, devices, or active ingredients to file their annual production for the 2019 reporting year is fast approaching. Pursuant to Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Section 7 (7 U.S.C. § 136e), “any producer operating an establishment registered [under Section 7] shall inform the Administrator within 30 days after it is registered of the types and amounts of pesticides and, if applicable, active ingredients used in producing pesticides” and this information “shall be kept current and submitted to the Administrator annually as required.”
Reports must be submitted on or before March 1 annually for the prior year’s production. The report, filed through the submittal of EPA Form 3540-16: Pesticide Report for Pesticide-Producing and Device-Producing Establishments, must include the name and address of the producing establishment; and pesticide production information such as product registration number, product name, and amounts produced and distributed. The annual report is always required, even when no products are produced or distributed.
EPA has created the electronic reporting system to submit pesticide producing establishment reports using the Section Seven Tracking System (SSTS). Users will be able to use SSTS within EPA’s Central Data Exchange (CDX) to submit annual pesticide production reports. Electronic reporting is efficient, it saves time by making the process faster, and saves money in mailing costs and/or courier delivery and related logistics.
Link to EPA Form 3540-16, as well as instructions on how to report, and how to add and use EPA’s SSTS electronic filing system are available below.
Further information is available on EPA’s website.
