January 2009 to August 2010
The former Ice House property was identified by the CDPHE to be a major asbestos spill under Colorado Regulation #8 Part B. Staff members performed oversight of the abatement and designed plans for on-site solid waste disposal of the spill.  The scope of work    included drafting an   application for certificate of designation  (CD), creating engineering designs, training, record-keeping, and constructing a closure plan related to the asbestos disposal site. Staff members also designed a solid waste disposal plan for the ACM and soil piles located on site. The plan addressed a variety of regulations, including Colorado Regulation #8, EPA, and National Emission Standards for Hazardous Air Pollutants (NESHAP) requirements, as they apply to asbestos disposal and encapsulation activities. Staff members managed the abatement contractor, ensured the usage of wet methods, monitored for visible emissions, and performed QA/QC compliance with NIOSH method 7202 for TEM air sampling. Staff continuously interfaced with both of the supervising CDPHE Divisions throughout all phases of the project.   They designed an alternative work plan to deal with the spill issues. Through this plan, the asbestos containing building materials and soil piles were encapsulated under concrete foundation walls and slab-on grade floors. The site was then filled with ACS, capped with clean clay soil and covered with asphalt. This plan saved the Count y more than one million dollars in construction fees.
