JANUARY 26, 2023 01 11 00 - 1

SECTION 01 11 00

SUMMARY OF WORK

PART 1 GENERAL

1.01 NOTICE TO CONTRACTOR

A. Prior to the construction of the previous landfill expansions in the Southern Expansion Area (SEA), the U. S. Army Corps of Engineers (USACOE) informed Orange County, Florida (Owner) that portions of the SES were included in the historical Pinecastle Jeep Range, a former World War II arms practice range and training facility. The Pinecastle Jeep Range was used for small arms firing, air tactics evaluations, and training demonstrations of strafing, practice bombing, air-to-ground rocket firing and high explosive bombing. USACOE Fact Sheet titled “Formerly Used Defense Site Program, Pinecastle Jeep Range,” dated July 2007, identifies two target areas on the SES east of State Road 417, one centered on the proposed Cell 11 area and one near the proposed Western Borrow Area (WBA).

B. Orange County had munitions Remedial Investigations (RIs) performed on three different occasions in 2008, 2009, and 2013. More than 5,000 subsurface anomalies were investigated during these RIs of which approximately 99 percent were culture debris (nails, railroad spikes, metal scrap). Further information and requirements regarding munitions are provided in Section 01 35 00, Health and Safety Requirements.

1.02 WORK COVERED BY CONTRACT DOCUMENTS

A. The Work shall include, but not be limited to:

1. Construction of Bays 20, 21 and 22, encompassing approximately 24 acres of lined Class I solid waste disposal area contiguous and adjacent to existing Bay 19. The Work includes locating and exposing the liner anchor system southside of Bay 19, and construction of the interface with Bay 19 liner for a contiguous Bay 20 lined disposal area as shown on the plans and details.

2. The U. S. Army Corps of Engineers (USACOE) informed Orange County, Florida (Owner) that portions of the Southern Expansion Site (SES) were included in the Pinecastle Jeep Range, a former World War II arms practice range and training facility. The current risk level overall for the SES is “low risk” based on the hazard severity and an incident “probability of occurrence,” making the site suited for future planned activities. Prudent procedures working within the site should include 3R (recognize, retreat, and report) training, and a standard operating procedure for reporting future potential munitions and explosives of concern (MEC) and materials potentially presenting an explosive hazard (MPPEH) to the appropriate authorities. An area referred to as the

SUMMARY OF WORK PW\JACOBS AMERICA\ORANGE COUNTY FL\D3625200
