Under the consent decree MSD was required to create a Long Term Control Plan (originally required in 1990’s) by June 2006. MSD spent two years creating its “Wet Weather Improvement Plan” (WWIP) which is essentially the Long Term Control Plan. The 2006 WWIP is a 24 volume (3 ring binders) which may still be available from MSD.
Over the next 3 years USEPA and MSD (Cincinnati and Hamilton County) negotiated the contents of the LTCP. Finally in 2008, USEPA declined to approve the 2006 plan. In 2009 USEPA agreed to a two phase approach and modifications to the consent decree.
Phase I included a Partial Remedy for the Lower Mill Creek and other projects. the full list is in attachment 1a and 1b of the 2009 WWIP.
Attachment 2 contained a list of phase II projects. The final list of phase II projects is due June 2017 per the global consent decree.
At the MSD breakfast in October 2016, Gerald Checco stated public meetings would be held on Phase II in the spring of 2017, before submission to USEPA in June.
