The Missouri EIS (Emissions Inventory System) web site presented a unique challenge due to the extensive number of complicated, multi-layered forms that must be entered into the online inventory.   The system consists of a client/server application, a web application and a web portal for the regulated community to electronically submit Emissions Inventory Questionnaires (EIQ).  RKV associates developed an information architecture and navigation scheme that allows the user to easily access forms in any part of the online inventory questionnaire.  The uppermost frame on the page contains perpetual navigation and simplifies completion of the lengthy questionnaire, and a set of shortcuts were developed to give direct access to frequently used worksheets or forms.  Tools were created such as form checkers and report builders, to give users feedback on their progress in completing the questionnaire.   A set of storyboards for the web site were developed to facilitate programming and the graphic look and feel of the site was designed with banners, buttons and other related aret.

The interactive MoEIS serves 176 state government users, including 6 regional offices, 8 county offices, 1 main office and 4 local agencies.  An estimated 3,000 to 6,000 private industry users are able to submit EIQs annually via the internet.  The system consists of approximately 300 client/server windows and 110 Web application pages.  The DB2 relational database management system (DBMS) consists of over 3.5 million records.
