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 o f giving you an electronic file, I can give you the details o f the grids that I used so you can enter it into your modeling: G rid 1 O rig in No. of Points Spacing X A x is 442000 22 100m Y A xis 4347200 11 100m G rid 2 O rig in No. o f Points Spacing X A x is 444200 5 100m Y A xis 4347500 3 100m Please let me know if you have any questions, D e b b ie Debbie Mulrooney Consulting Engineer D uPont Engineering Technolog y (D uET) Environm ental Engineering Brandyw ine 9430/ V o ice: 302-774-8083- / Fax: 302-773-1202 debbie.j.m ulrooney(S)usa.dupont.com D uPont Engineering Technology : Find the right consultant: http://engineering.dupont.com /env_engg/ http://engineering.dupont.conn/resources/techdir.htrn D JM 0Q 0343 E ID 5 0 2 5 8 1
