Gulfstream Overview
What made Gulfstream unique?
• First natural gas transmission pipeline built in the Gulf of Mexico
• Largest pipeline in the Gulf of Mexico
! 420 miles of 36" OD, high pressure rating of 2180 psig MAOP
• Designed with no compression offshore
• First pipeline on east side of the Gulf of Mexico
• Florida’s first natural gas transmission pipeline in 40 years
• Only offshore gas pipeline to make landfall in Florida
! Strict dry gas specs ensure minimal quantity of liquids delivered
• Other technological breakthroughs during construction and
commissioning

Offshore Mitigation
Developed mitigation plan in conjunction with the Florida
Department of Environmental Protection, the Florida Marine
Research Institute, the U.S. Army Corps of Engineers, the
Hillsborough County Environmental Protection Commission, the
Minerals Management Service, and the National Marine Fisheries
Service.
Federal Waters
• Added new limestone hard bottom
• 49.4 acres of mitigation
• 153 man-made reef modules
• 130,000 tons of limestone
• Monitoring up to 10 years
Environmental
Offshore Mitigation
State Waters
•
19.74 acres of mitigation
•
Accomplished using 100 20X24
shallow water reef habitat modules
•
Required 5,000 tons of Florida
limestone
•
Required that divers physically
remove and transplant soft and
hard coral from the proposed pipe
lay area
Environmental
Environmental Mitigation
Onshore
• Spoil Island (65 acres)
!Created bird sanctuary w/ Audubon & Port
• Harbor Key (100 acres)
!Exotic plant removal
• Lake Wales Site (398 acres)
!Created and enhanced wetlands & uplands
!Planted over 117,000 trees
• Manatee Site (181 acres)
