strict environmental standards, especially when crossing wetlands and 

 water courses, to minimize disturbances to fish and wildlife and their 

 habitats.

Leaks from tanks, valves, or pipelines in the storage tank area, 

 if they occur, may contaminate storm water confined in tank diked areas. 

 Normally the dikes built around the tanks to retain the liquid in case of 

 accidental rupture are used to collect runoff water [7]. This stormwater 

 system is separate from the stormwater system of the entire complex. The 

 potentially contaminated water from the dike areas is placed in the 

 waste treatment system, cleaned of oil with the API oil skimmer, aerated, 

 treated and discharged. Runoff areas outside the dikes may require 

 retention or settling ponds to collect and store the water before it is 

 released but generally does not receive the extensive treatment offered 

 for areas which come in direct contact with hydrocarbons. 



Subproject: Solid Waste Disposal (SP-13) 



Disturbing Activity: Solid waste disposal 



The major sources of solid waste problems from a marine terminal 

 system are storage tank and pipeline sludges. Periodically, sediment 

 sludges which have built up in pipelines and tank bottoms are removed to 

 containment facilities to prevent infiltration of toxic compounds into 

 adjacent soils, around or surface waters. Oil brine separator sludges 

 also contain toxic compounds, including ammonio, sulfur, and ferric 

 chloride, that require special storage and treatment. In the past, 

 solid wastes were weathered, then buried in designated sludge pits. 

 In some states, licensed contractors remove and dispose of the wastes, 

 using state-approved methods. 



Subproject: Industrial Wastewater Systems (SP-14) 



Disturbing Activity: Wastewater disposal 



Tanker bilge and ballast waters are the major sources of wastewater 

 at a marine terminal. Other wastewater sources include domestic sewage 

 cooling water, and stormwater runoff (and when applicable, process 

 water). Bilge water accumulation rate for a 20,000 dead-weight ton 

 tanker has been calculated at 80 gallons per minute, or about 115,000 

 gallons per 24 hours of operation [7], Bilge water accumulated by 

 tankers, tug boats and other service boats at a marine terminal is con- 

 tar^inated by fuel and oil leakage, and by metallic compounds from the 

 machinery. The bilge water requires collection and treatment before it 

 is discharged to receiving waters.
