Chlorpyrifos Revised Risk Assessment and Agreement with Registrants
First Aid Instructions Revised for Pesticide Product Labels
Project Safe Send Pesticide Collections Scheduled
In case you haven't heard the news, NDSU got hammered by a flood during the late night and early morning hours of June 20 and 21. Seven to eight inches of rain fell over a four hour period. This quickly over-whelmed drains and a lift station on the north end of campus failed. The result was tens of millions of dollars worth of damage to the campus and massive disruption of teaching, research, and extension activities.
The pesticide program did not suffer any long term damage. All our records, computer equipment, and publications were untouched by the water. However, the campus was closed for a couple of days and telephone systems were knocked out. We fell behind in processing certifications but the backlog was cleared up by the 26th of June.
Communications continues to be a problem and this will probably plague our program until the end of July. However, we have adopted some measures to help. What follows are some ways in which you can reach us in order of preference:
If you attempt to call us via cell phone or through the Plant Science Department please realize that we do not have voice mail capability so you may get a busy signal, the telephone may ring without answer, or you may get a recording from the main NDSU switchboard telling you that the lines are full or temporarily out of order. Be patient, we are trying to work through this set back the best we can.
Keep your head above water,

EPA has released its revised risk assessment and announced an agreement with registrants to eliminate and phase out certain uses of the organophosphate pesticide chlorpyrifos. Also known as Dursban, Lorsban, and other trade names, chlorpyrifos is one of the most widely-used insecticides in the U.S., both in agriculture and in and around the home.
The Food Quality Protection Act, enacted in 1996, sets a more stringent safety standard for most pesticides and offers special protection for children. In meeting the tough safety standard, EPA believes it can do a better job of protecting children and others by further reducing exposure to chlorpyrifos and providing the increased margins of safety now mandated by Federal law. These use modifications also will improve safety for workers who apply chlorpyrifos and for the environment.
EPA and the registrants have agreed to the following modifications:
The agreement phases in the various restrictions and cancellations to address higher risk uses of chlorpyrifos first. Because much of the risk reduction involves increasing margins of safety, it is reasonable to focus first on the uses that achieve the greatest risk reduction for children. Allowing other uses to continue for a specific period of time will help ensure that appropriate alternatives are available for a reasonable and orderly transition.
For additional materials on the chlorpyrifos decision, or for information on other aspects of the Agency's pesticide regulatory program, contact EPA's Office of Pesticide Programs at (703) 305-5017, or visit our web site, www.epa.gov/pesticides.
It is important the users of Dursban and Lorsban note that this is not a recall or a ban by EPA, so here are some points to consider:

On April 11, EPA proposed to revise the format and content of first aid advice on all pesticide product labels to make them easier to read. While companies can start to use this revision immediately, the Agency will accept public comments for 30 days. The revision incorporates recommendations by the medical community and the Consumer Labeling Initiative.
Changes to labels will include: section headings labeled First Aid instead of Statement of Practical Treatment; new format designs; as well as first aid advice for each pathway of exposure through the mouth, skin, inhalation, and eye. The goal is to revise all product labels by October 1, 2001.

BISMARCK — Unusable pesticides can be brought to any one of 16 Project Safe Send collection sites for safe and free disposal during the month of July.
"Project Safe Send is a perfect opportunity for farmers, ranchers, pesticide applicators and dealers to get rid of old pesticides, such as insecticides, weed killers and seed treatments," said Commissioner of Agriculture Roger Johnson. "Project Safe Send will take responsibility for these old pesticides and get rid of them safely and at no charge."
Johnson urged anyone with unusable pesticides, including household and garden products, to take part in the collection.
"Project Safe Send is primarily intended for agricultural pesticide users, but everyone — including homeowners who have any unusable pesticides — is welcome to take part," Johnson said.
Persons who plan to participate in Project Safe Send can call the North Dakota Department of Agriculture (NDDA), toll-free at 1-800-242-7535, for guidelines on transporting pesticides to the collection sites and for exact directions to the sites. People with large quantities of unusable pesticides should call NDDA to pre-register.
All sites will be open from 9 a.m. to 3 p.m. local time. Dates and directions to collection sites are listed below:
All collection sites are located at North Dakota Department of Transportation (DOT) facilities, unless otherwise noted in the following communities:
