EPA Orders Five Illinois Feedlots To Stop Discharges to Nearby Streams
EPA Region 5 has ordered five Illinois feedlots to stop all unauthorized discharges of manure and wastewater and comply with the Clean Water Act. EPA also ordered several of the feedlots to apply to the Illinois EPA for discharge permits under the National Pollutant Discharge Elimination System. EPA has not assessed penalties as part of these actions.
Settles With Target on Pesticide Violations
EPA Region 5 has filed a consent agreement and final order with Target Corp. on alleged violations of federal rules on the labeling, distribution, and sale of pesticide products. A $40,950 penalty has been assessed against the company as part of the settlement. According to EPA, Target sold and distributed unregistered pesticides from its stores and on its Web site. The products are Antimicrobial Toilet Seats, three sizes of Home Ultimate Mattress Pads, Home Ultimate Pillows, and Cleaner With Bleach. The toilet seats, mattress pad, and pillows made "germ-killing" claims. The Cleaner With Bleach compared the product's properties to a similar, registered disinfectant bathroom cleaner sold by a competitor. Target is removing the pesticidal claims from these products.
77 Risk Assessment Available for Comment
EPA has released its risk assessment and related documents for the antimicrobial pesticide Busan 77 and has opened a public comment period on these documents. The public is encouraged to suggest risk management ideas or proposals to address the risks identified. EPA is developing a Reregistration Eligibility Decision (RED) for Busan 77 through a modified four-phase public participation process. Comments must be received on or before November 27, 2007.
EPA Proposes Penalty for Milk Plant in Maryland
EPA has proposed a $282,871 penalty against the operators of a milk processing plant in Laurel, Maryland, for failing to report an accidental release of at least 400 pounds of ammonia from the plant's refrigeration system in July 2006. EPA alleges that the Maryland & Virginia Milk Producers Cooperative Association, Inc., which owns and operates the Laurel plant, violated federal requirements for hazardous chemical reporting when it failed to immediately report the ammonia release to local, state, and federal emergency management agencies. The accidental release occurred while conducting maintenance on the plant's refrigeration compressors. The milk cooperative also failed to provide followup reports to state and local emergency officials.
Settles With California Wholesalers for Pesticide Violations
EPA settled with Four Seasons General Merchandise, Inc., a Los Angeles, California, non-durable goods wholesaler for $24,960 and with 26 California Bazar, a Vernon, California, company for $9,360 for the alleged sale and distribution of unregistered pesticides, a violation of federal pesticide law. EPA alleges that Four Seasons sold the unregistered pesticides Clorox Disinfecta -- a Mexican version of Clorox bleach -- and Citronella Incense mosquito coils to retailers in Guam and California on five occasions between August 2006 and March 2007. In addition to the fine, the wholesaler has agreed to return all unused products to the original seller. EPA alleges that 26 California Bazar sold the unregistered pyrethroid pesticide, Camping Mosquito Sticks, to Guam retailers on two occasions. In addition to the fine, the company has agreed to cease selling the product.
EPA Issues Allethrin Reregistration Eligibility Decision
EPA has released its Reregistration Eligibility Decision (RED) for the allethrin series of pesticides (bioallethrin, esbiol, esbiothrin, and pynamin forte). The Agency's risk assessments and other related documents also are available in the allethrins docket. The allethrins are synthetic pyrethroids used as insecticides on both indoor and outdoor use sites. Although the allethrins RED was signed on June 30, 2007, certain components of the document, which did not affect the final regulatory decision, were undergoing final editing at that time. These components, including the table of contents and the summary of labeling changes, have been added to the allethrins RED document. None of these additions or changes alter the conclusions documented in the June 30, 2007, allethrins RED. Few comments were received during the earlier comment periods for this reregistration case, and the issues related to this pesticide were resolved through consultations with stakeholders. The Agency therefore is issuing the allethrins RED without a comment period.
Proposes to Terminate Special Review of Dichlorvos (DDVP)
EPA has published a Proposed Determination to Terminate Special Review for the pesticide dichlorvos (DDVP). Since the initiation of the special review, additional data have become available. Based in part on these data, the Agency has changed its assessment of some of the risks associated with DDVP and has modified the terms and conditions of DDVP registrations accordingly. Moreover, during the recently concluded reregistration process for DDVP, EPA conducted an intensive and public review of whether DDVP registrations meet the FIFRA standard for registration, culminating in the Agency's 2006 Interim Reregistration Eligibility Decision (IRED) for DDVP. Through the reregistration processes the Agency resolved remaining concerns regarding cancer and cholinesterase effects. Based on the IRED, requested label amendments, and the voluntary cancellation of uses by the registrant, EPA has determined that the risks that were the basis of the Special Review are no longer of concern and, therefore, the Agency is proposing to terminate the special review of DDVP. To the extent that the Agency further revises its assessment of DDVP, it will do so outside of the special review context. Comments must be received on or before October 26, 2007.
Carbamate Revised Cumulative Risk Assessment Available for Comment
EPA has released its revised cumulative risk assessment for the N-methyl carbamate group of pesticides, and has opened a public comment period on this document and other support documents. As required by the Food Quality Protection Act, a cumulative risk assessment, which evaluates exposures based on a common mechanism of toxicity, was conducted to evaluate the risk from food, drinking water, residential, and other non-occupational exposures resulting from registered uses of N-methyl carbamate pesticides. The N-methyl carbamate group includes aldicarb, carbaryl, carbofuran, formetanate HCl, methiocarb, methomyl, oxamyl, pirimicarb, propoxur, and thiodicarb. Comments must be received on or before November 26, 2007.

Scientific Advisory Panel To Discuss Potential Atrazine Effect on Amphibian Gonadal Development; Other Atrazine Studies
On October 9-12, 2007, EPA will present to the FIFRA Scientific Advisory Panel (SAP) the Agency's analysis of the latest data from laboratory and field studies investigating a possible connection between amphibian gonadal development and the herbicide atrazine. Based on this thorough analysis, EPA finds that atrazine does not adversely affect amphibian gonadal development, and believes there is no compelling reason to pursue additional testing of atrazine for amphibian gonadal effects. The Agency is also awaiting the results of atrazine human cancer studies, and has received and is analyzing additional monitoring data from community water systems and data from an ecological watershed monitoring program. EPA will be asking the panel to comment on the Agency's approach and criteria for evaluating all the studies. The Agency has also posed a number of specific questions to the SAP regarding studies that the registrant conducted at EPA's request. Almost the entire first day of the 4-day meeting is reserved for public comments. A white paper and other background information on EPA's regulatory actions and decisions for atrazine are in the atrazine docket, EPA-HQ-OPP-2007-0498, at regulations.gov.
EPA Orders Oklahoma Ranch To Stop Unauthorized Discharges
EPA has issued a cease and desist administrative order to the Rocking BS Ranch near Wetumka, Oklahoma, for violations of the Clean Water Act, including an unauthorized discharge of pollutants flowing into an unnamed tributary to Middle Creek and then into Middle Creek in Hughes County, Oklahoma. The ranch, an unpermitted Concentrated Animal Feeding Operation, has been ordered to stop immediately all discharges of pollutants from its facility. The ranch has been given 7 days to properly reconstruct a lagoon spillway where the discharge occurred, and 30 days to finalize the reconstruction and survey the lagoon to determine the quantity of solid manure buildup and total capacity of the lagoon.

The N-Steps center is a "one-stop shop" for national, regional, and local nutrient criteria development.
EPA To Regulate Ion Generators as Pesticides
EPA has announced that machines which generate silver ions or other substances for pesticidal purposes will be regulated as pesticides. The September 21 Federal Register notice clarifies the Agencys position on the distinction between devices and pesticides with regard to ion-generating equipment and explains why such equipment will now be regulated. EPA will identify the information needed for an application for registration, and will give those products currently out of compliance time to obtain registration. The notice is not an action to regulate nanotechnology. EPA has not yet received any information that suggests that these products use nanotechnology. The Agency will evaluate any applications to register this type of equipment according to the same regulatory standards as other pesticides.
Registration Review Work Plans Available for Nine Pesticides
EPA has posted final work plans for registration review of the pesticides clofentezine, cyromazine, fenarimol, fomesafen, linalool, trichoderma species, triflumizole, paclobutrazol, and pyridate. These work plans are available through EPA's Registration Review Status page. The plans include the expected timelines for registration review. They also address any public comments in the initial registration review dockets.
Posts Online Update on Manure Digesters, Related Technology
AgSTAR has developed a Web-based update to highlight news about manure digester projects and other items of interest in the field. Many of the articles are summaries of online news stories, with hyperlinks to the original sources. The update also provides timely postings about applicable grants and calls for proposals, noteworthy events, and applicable regulatory policy changes. AgSTAR is a voluntary effort jointly sponsored by EPA, the U.S. Department of Agriculture, and the U.S. Department of Energy. The program encourages the use of methane recovery (biogas) technologies at confined animal feeding operations that manage manure as liquids or slurries. These technologies reduce methane emissions while achieving other environmental benefits.

EPA Settles With Arizona Chemical Manufacturer
EPA and Oasis Nursery and Hardware Products, Inc., a Tucson, Arizona, chemical manufacturer, have agreed to a $2,500 penalty for Oasis Nursery's alleged sale or distribution of unregistered and misbranded pesticides. The violations were discovered during a September 2006 inspection performed by the Arizona Department of Agriculture. The product in question was Root Brute Sewer Treatment Root Destroyer. The Root Brute contained an active ingredient from an unapproved source, which rendered the pesticide unregistered. In addition, the pesticide was misbranded because its labeling failed to include the word danger, a required warning for this product.
Files Complaint Against California Grocery Distributor
EPA filed an administrative complaint against Unified Western Grocers, a Los Angeles-based grocery distributor, seeking $538,200 for the alleged sale and distribution of an unregistered pesticide. Unified Western Grocers allegedly sold and distributed "Western Family Cleanser with Bleach," an unregistered product that states on the label that it "wipes out most household germs, including Staph, Salmonella, and Pseudomonas." The case was based on inspections conducted by the State of Californias Department of Pesticide Regulation and the State of Hawaiis Department of Agriculture in 2005 and 2006.
Pesticide Registration Review Dockets Open for Comment

EPA Issues Technical Document on Using Load Duration Curves in Development of Total Maximum Daily Loads
EPA has issued a technical document called "An Approach for Using Load Duration Curves in the Development of TMDLs." The duration curve approach allows for characterizing water quality conditions at different flow regimes. The method provides a visual display of the relationship between stream flow and water quality. The document describes basic steps needed to develop duration curves, which identify loading capacities, load and wasteload allocations, margins of safety, and seasonal variations. It is written for TMDL practitioners who are familiar with relevant technical approaches and legal requirements. The guide also discusses some considerations and limitations in using the approach, and includes several case examples.
