I-35 Construction Project and Erie Pier Material

Meeting #2 – January 23, 2011

•The requirement for a standing BUD duplicates the permit issued from MPCA’s Water Quality division.

•Both Water Quality and Solid Waste Programs at the MPCA use the Soil Reference Values (SRV) as their clean standard.

•This issue brings forward a legal question of whether a determination from one MPCA program can cover other programs as well.
