been the primary sources of habitat destruction in the region. If 

 dredging and filling operations are significantly expanded, much of what 

 is left will be destroyed. Air pollution will increase if significant 

 hydrocarbon vapor emissions from additional tanker loading operations 

 occur in the ports. Smog from the Los Angeles basin is currently caus- 

 ing damage to trees up to 65 miles away in the San Bernardino and Los 

 Padres National Forests. 



5. Special Features . Santa Catalina and San Clemente Islands are 

 part of Los Angeles County. Both provide breeding sites for seabirds 

 and mammals. The OCS Task Force identified Santa Catalina as a possible 

 crew staging area if the island's owners, the Wrigley Family, consent to 

 this use. At present, the family controls the use of the Island in agree- 

 ment with the County Parks Department. 



According to the Parks and Recreational Department, Los Angeles' 

 beaches are the most heavily used coastal recreation areas in Southern 

 California (76,770,974 visitors in 1971). These areas have been used 

 so heavily that one of every three families seeking use of the beach 

 were turned away for several weeks in the summer of 1976.

1. Development and Production . Offshore oil and gas is currently 

 produced from fixed platforms and artificial islands on state lands in 

 Orange County (See Appendix I, Maps 19 and 20 and 22). Oil from 

 two state tideland fields is currently being produced from onshore wells 

 slant-drilled into offshore formations.
