The purpose of the Task was to complete National Emission Data System (NEDS) forms for area source emissions for each county in the state of Iowa. These forms are suitable for key punching. Input data were obtained, insofar, as possible, from the appropriate state agencies and the state's Implementation Plan. Where agency data were insufficent to complete the NEDS forms, entries were determined following procedures outlined in the manual for area source coding. The NEDS area source coding form is illustrated. The procedures are detailed for completing the form and refer to the specific information fields thereon.
