Manufactured Gas Plant (MGP) Remediation - Update (B)
Staff is providing an update on the GRU MGP Remediation. Phase 1 construction is currently underway by the remediation contractor Environmental Consulting & Technology (ECT). Phase 1 remediation work began in July 2009 and is scheduled to be substantially complete by June 2010. Phase 2 work is scheduled to begin this month and to be substantially complete by September 2010.
Explanation
In 1990, GRU purchased the assets and liabilities of former Gainesville Gas Company (GGC). In 1992, a FDEP Consent Order was issued to the City to investigate and remediate the environmental impacts attributable to the Manufactured Gas Plant formerly operated by GGC. At this time GRU has executed a contract with ECT as the specified source contractor and construction is underway.
On July 1, 2009, GRU issued a Limited Notice to Proceed (NTP) to ECT to begin work on the associated stormwater piping and structures in the non-FDEP funded areas of the site. At that time work in the remaining areas was on hold pending FDEP approval of Petroleum Cleanup Preapproval Program funding. FDEP was subsequently secured, and on September 21, 2009 GRU issued the full NTP to ECT for Phase 1 of the remediation.
Phase 1 construction is well underway; a total of over 11,000 tons of contaminated material have already been removed from the site. Phase 1 construction is now scheduled to be substantially complete in June 2010, which is about 60 days behind the initial schedule. This is primarily due to delays encountered in the sheet piling installation and to the start-up of the dewatering water treatment system.
Phase 2 of the remediation is located immediately adjacent and to the south of the Phase 1 area. Construction in the Phase 2 area is scheduled to begin this month, and to be complete by August 2010. Although the estimated volume of contaminated soil in the Phase 2 area is approximately double that of Phase...
