BRIEFS (2/7/03)
CONTENTS:
EPA has concluded that atrazine may continue to be used, provided all the precautions and the new specific measures are implemented to reduce risks to drinking water and that risks associated with exposures from food are not of concern. Exposure from residential uses and exposure to workers are low and have been addressed by changes in product use conditions. The provisions of this action, contained in the IRED, have also been incorporated into an agreement with the principal registrant of atrazine, Syngenta. Under this approach, Syngenta is required to conduct a specialized testing program in vulnerable watersheds on a weekly basis to monitor "raw" drinking water during high-use periods for this pesticide. If EPA’s regulatory safety standards are exceeded in raw drinking water, atrazine use is cancelled in that geographic area. This more stringent approach requiring weekly monitoring of "raw" drinking water during certain times of the year augments monitoring conducted under the Safe Drinking Water Act (SDWA) of "finished" drinking water. For all other areas where atrazine might be used, monitoring of finished drinking water for atrazine is rountinely required under the Safe Drinking Water Act (SDWA). For these systems, detections approaching the Maximum Contaminant Level (MCL) for atrazine will trigger additional monitoring and regulatory oversight. EPA‘s existing MCL remains protective and in place. If the MCL is violated, the pesticide manufacturer is required to take the steps necessary to assist the community water system return to compliance with the atrazine MCL. In this way EPA is allowing flexibility to account for local conditions while assuring that safety standards are met. The costs involved in this program will be the responsibility of atrazine manufacturers as part of their product stewardship. EPA is continuing to evaluate the potential effects of atrazine on amphibians, which continue to be the subject of additional research and analysis. EPA intends to submit the issue of atrazine effects on amphibians for independent scientific peer review by the FIFRA Scientific Advisory Panel in June, and anticipates completion of an amended IRED, including consideration of effects on amphibians, by Oct. 31, 2003.

PRIMISULFURON-METHYL (BEACON, CGA-136872, RIFLE) IS SAFE
Primisulfuron-methyl is a urea herbicide that is used on crop and non-crop areas for the control of grass weeds and many kinds of broad-leaved weeds. The compound is a selective postemergence systemic herbicide that is rapidly absorbed by plants and transported throughout the plant roots and foliage. The herbicide works by blocking cell growth in the active growing regions of the plant. The herbicide also acts to inhibit photosynthesis. Primisulfuron-methyl may be found in other herbicide formulations such as 2,4-D, dicamba, cyanazine, bromoxynil and atrazine. Contact: Christina Scheltema, Special

TOLERANCE REVOCATIONS FOR OXADIAZON (CHIPCO, RHONSTAR) FOR FOOD USES
EPA published a notice on August 1, 2001 proposing revocation of tolerances of two pesticides: oxadiazon and the insecticide tetradifon. EPA received a request to retain tolerances for tetradifon. EPA is evaluating issues described in the comment on tetradifon and will not take final action on these tolerances now. Commodities containing pesticide residues not covered by a tolerance are considered to be adulterated and are subject to seizure. A tolerance must meet the current safety standard established under FQPA if it is to be retained. (6)
DOES THE FOREST SERVICE NEED A PERMIT UNDER THE CLEAN WATER ACT?
Results from this government action are not expected soon unless the court does not grant the request for rehearing. In the meantime, the Forest Service is pursuing the process for an NPDES permit in the state of Oregon in order to implement an eradication project this spring where Btk will be aerially applied for control of a Gypsy Moth infestation. The FS is working cooperatively with the Oregon Dept. of Agric. and the Dept. of Environmental Quality. Date: January 8, 2003 © Inside Washington Publishers (Sent from USDA/CSREES) EPA and Justice Department investigators are targeting a network of pesticide manufacturers and suppliers in the United States and overseas who allegedly have been selling counterfeit versions of pesticides that are widely used to fight mosquitoes that may carry the West Nile virus, sources say. The investigation is one of the largest ever into the sale of alleged imitation pesticides, according to one federal investigator, and sources say the inquiry may prompt a rethinking of EPA policies aimed at protecting the distribution of pesticides used for public health purposes. Federal investigators have been scrutinizing the Sierra Chemical and Supply company, located in Anniston, AL, for allegedly distributing adulterated versions of popular pesticides. Sources say investigators have traced the company's distribution of its pesticides to municipalities across much of the Southeast and parts of the Midwest. The investigators obtained a search warrant and raided Sierra's facility in Anniston on Sept. 25. Sources say that investigators removed samples of pesticide chemicals from the premises along with color photocopied labels of the pesticide Aqua-Reslin, which is a mosquitacide widely used by local governments to kill mosquitoes that may carry the West Nile virus. Aventis Crop Science, which is owned by Bayer, produces Aqua-Reslin. A key investigator says that Bayer has been informed of the investigation, and a Bayer spokesman says that Bayer is cooperating with any investigation into the adulteration of its products. Investigators are examining whether Sierra sold imitation versions of Aqua-Reslin and several other pesticides. Investigators are also examining whether Sierra doctored the formulations of brand-name pesticides. Federal sources would not comment on the names of the other pesticides, but a state official familiar with the issue says investigators were scrutinizing whether Sierra was also selling counterfeit versions of Permanone, another mosquitacide produced by Aventis. Sources say investigators are focusing on Sierra's distribution activity in 2001, potentially extending as far back as 1997. Sources familiar with the investigation say it may lead EPA officials to reconsider the regulations surrounding the distribution of pesticides, especially pesticides that have a public health function. Currently, EPA requires any person seeking to manufacture, re-label or distribute a pesticide, to register its facility with the agency. Any pesticide sold in the United States must have a valid EPA registration number printed on its label. Registered facilities must report the amounts of pesticides they produce and sell from the facility. However, producers and distributors are at no point required to test the contents of their pesticides before selling them to other distributors, private users or municipal governments. But sources say additional regulations governing the distribution of public health pesticides may not stop the kind of possible crimes for which Sierra is under investigation. Investigators are expecting to file felony criminal charges in the upcoming months against Bill Murphy of Glenco, AL, the owner of Sierra Chemical, for allegedly violating federal copyright and trademark laws, as well as misdemeanor charges for violating provisions in the Federal Insecticide, Fungicide and Rodenticide Act governing labeling and adulterated pesticides, sources say. In addition, investigators are looking at potential violations of customs laws, claiming that Sierra may have imported much of its raw materials from overseas. Murphy denies any deliberate mislabeling of pesticides, while conceding that he may have not followed federal pesticide regulations to the letter of the law. Murphy admits to "some wrongdoing, mostly out of ignorance." "We did some things wrong, particularly when we first got started," Murphy says. But he adds that as he has gained more experience in the pesticide industry, his company has had no problems since. "Our material is extremely well-received by those who use it," he says. Federal investigators are looking at whether Sierra made copies of Aqua-Reslin labels and placed them on canisters of Sierra's own pesticide formulations, which sources say was a rough approximation of Aqua-Reslin. Sources say Sierra sold pesticides carrying the Aqua-Reslin label to municipalities in states across the Southeast and parts of the Midwest, including Georgia, Alabama, Louisiana, Ohio and Illinois, at prices well below the general market rate for the brand-name pesticide. Sources estimate Sierra may have accumulated at least hundreds of thousands of dollars in revenue from the sale of these pesticides. Murphy says he purchased Aqua-Reslin labels that he assumed were ready to use. He then purchased Aqua-Reslin, poured the pesticide into different containers, and then placed the labels on the new containers. "We shouldn't have repackaged anything," Murphy says, while denying that he placed the labels on his own product. Sources familiar with the investigation say that tests of Sierra's pesticides revealed chemical concentrations that were sometimes too high and other times too low to match the concentrations of chemicals in Aqua-Reslin. "It was pure Russian roulette," the source says. "It would have some efficacy, but not as high," says another source, adding, however, that some of the pesticides were "close." Investigators are also examining potential criminal violations in Sierra's supply chain, which sources say investigators have traced back to a British chemical company. Investigators believe that a middle man familiar with chemical suppliers in Europe may have acted as a broker between Murphy and the British company, a transaction that sources say may have violated U.S. customs laws governing the import of chemicals. Sources say that among the possible customs violations that investigators are pursuing, officials are examining whether proper tariffs were paid on the imported chemicals. Sources say that investigators are also examining other suppliers, both domestic and international, to determine whether Sierra may have obtained raw materials from other facilities. (8)
ENDANGERED SPECIES CONSULTATION PROCESS - COMMENTS DUE 3/10
Under the Endangered Species Act, EPA must ensure that registration of pesticides will not jeopardize the continued existence of threatened or endangered species or result in the destruction or adverse modification of critical habitat. Through an Advance Notice of Proposed Rulemaking published in the Federal Register, the federal government is seeking comments on a variety of approaches to improve and enhance the consultation processes among agencies. Improving the consultation process will directly benefit listed species and their habitat by ensuring that the potential effects of pesticides are examined in a timely and comprehensive manner. EPA routinely evaluates the potential effects of pesticides on wildlife. EPA also consults with the wildlife agencies about pesticide uses that may affect listed species. For many years the federal government has not systematically considered how to improve the efficiency of the consultation process. As a result of EPA's ongoing reexamination of previously registered pesticides, as well as recent litigation, the three agencies anticipate a significant increase in the number of future consultations. Thus, the three agencies have agreed to review and where necessary improve, the current consultation process so that timely regulatory decisions can be made that provide needed protections for species, without placing unnecessary burdens on farmers, homeowners and other pesticide users. These agencies are further coordinating this effort with the USDA to ensure that any modifications to the current processes or regulations take into account the need to consider the potential impacts on food and fiber producers. Similarly, the agencies are working to establish the most effective consultation process that will enhance stakeholder involvement and education around the endangered species protection efforts for pesticides. Specifically, the agencies are soliciting comments on the following approaches, such as:

NATIONAL PESTICIDE PRACTICE SKILLS GUIDELINES FOR MEDICAL & NURSING
PRACTICE
The purpose of the Initiative is to improve the recognition, management, and prevention of pesticide poisonings and overexposures by health care providers in the United States. The Initiative takes a strategic approach for incorporating environmental health information into the education and practice of health care providers, using pesticides as a model. The National Guidelines are a major step toward improving primary care practitioners' environmental knowledge and skills. For more information, contact the Project Director Leyla Erk McCurdy, Health Environment Programs 202-261-6488, mccurdy@neetf.org Michigan State University Extension has published a new book for fruit growers that responds to the increasing number of regulatory and environmental restraints on fruit production systems. To help fruit growers and consultants transition to more sustainable practices, MSU specialists collaborated with them to produce this publication explaining how ecology works within fruit production systems. The book explores how those who want a biologically intensive fruit production system must look at their farm as an ecosystem where organisms form an integrated web that allows farms to function. With knowledge of these interactions, growers can effectively modify their own production system. To enhance its appeal for its audience, Fruit Crop Ecology and Management was written and designed to explain ecological principles within a farming context using colorful photos and illustrations along with practical examples. Sample pages and content description can viewed at the MSU IPM Program website: http://www.msue.msu.edu/ipm/Pubs_eco.htm Fruit Crop Ecology and Management is a
collaboration of 20 authors from ten disciplines, and over 25 reviewers
from several states and the Netherlands. The teams’ expertise included
agricultural economics, agricultural journalism, agricultural meteorology,
entomology, farming, horticulture, integrated pest management, nematology,
sociology, sustainable agriculture, and plant pathology. Growers, crop
consultants, and food processors helped select the content and served as
authors and reviewers along with faculty and Extension agents. The book
includes information for tree fruit and small fruit grown in the Great
Lakes states with principles that can be extended beyond that region. The
soft-bound 104-page book sells for $16 ($19.20 international orders) and
