This assessment is intended to provide state and local agencies with information on whether their monitoring
networks still meet the monitoring objectives, whether new sites are needed, whether existing sites are no longer
needed, and whether new technologies are appropriate, as required by 40 CFR Part 58.10(d).  The assessment’s
recommendations are non-binding; rather, each state/local agency will decide, as part of their annual network
review (either this year or next year), whether to make any of the recommended changes.  Furthermore, although
there is no requirement for a periodic network assessment for tribal monitoring, this information may also be helpful
to Midwest tribes in evaluating their current and desired future monitoring activities.
