Update February 23, 2012:
The dispute resolution (Petition for Dispute Resolution) hearing on the Western Area Monitoring Plan was heard on Wednesday, January 11, at 1:30 PM, at 101 E. Huron Street, second floor, Ann Arbor, in the court room of the Honorable Donald E. Shelton.
Honorable Judge Shelton ruled for Gelman Sciences d/b/a PALL Life Sciences, Inc.'s (Defendant)at the hearing "without prejudice" .The ruling allows for the MDEQ to still rejoin the issue with better supporting documentation. The outcome of the ruling is that Gelman/Pall Life Sciences will not be required to install additional compliance monitoring wells, as requested by the MDEQ.The proposed additional compliance monitoring wells were to be installed at proper depths and closer to the known plume(s) at the core area, to aid in determining if the Consent Judgement requirement of non-expansionis achieved.
Also available for review is the Plaintiff's Brief in Response to Defendant's Petition for Dispute Resolution.
