not come into direct contact with the petroleum and is not thereby 

 contaminated. However, it does present potentially significant thermal 

 pollution problems and directly kills organisms sucked in with the 

 cooling water. In addition, land subsidence may be caused in certain areas 

 by excessive aquifer withdrawal. 



Regulatory Factors 



A petrochemical complex must comply with a complex set of air and 

 water pollution control criteria derived in part from Federal legislation 

 and in part from state and local programs. Site specific controls 

 related to dredge and fill, pipelines, water supply, and transportation 

 may also require permits or approvals from various public agents. 



State and Local Role ; State and local legislation and other 

 actions aimed at reducing the potential for adverse effects on the 

 natural environment in particular, may be stimulated by the chreat of 

 location of major petrochemical complexes outside present ports and
