Environmental Instructional and Informational Memoranda

Environmental Instructional and Informational Memoranda ( I&IMs) provides staff, contractors, or other third parties with the required method, process, specifications or orderly way of accomplishing a function or task or a set of actions or operations which have to be executed in the same manner in order to achieve intended results. VDOT assumes no responsibility for any incorrect outcomes or damage resulting from the use of this information.  

Please note that the Environmental Division is in the beginning phases of converting all existing Environmental Memoranda (EM) to I&IMs. Existing EMs will be converted by individual program area and on an as-needed basis.
