Unfortunately, this receptor grid is from the Lakes program, which doesn't have an option to export a receptor grid by itself the way Trinity's program does. So, in lieu of giving you an electronic file, 1can give you the details of the grids that I used so you can enter "rtinto your modeling: Grid-1 Origin No. of Points Spacing XAs 442000 22 100m YAMS 4347200 11 100m Grid 2 Origin No. of Points Spacing XAxis 444200 5 100m YAxis 4347500 3 100m Please let me know tf you have any questions, Debbie Debbie Mulrooney Consulting Engineer DuPont Engineering Technology (DuET) Environmental Engineering Brandywine 9430/ Vote: 302-774-8083. / debbie.j.muli"ooney@usa.dupont.com Fax: 302-773-1202 DuPont Engineering Technology : Hnd the right consultant: http://engineering.dupont.com/env.engg/ http://engineering^upontconn/resources/tEchdir.htni DJM000343 EID502581
