Level of infrastructure is an indicator of the extent to which the petroleum industry along the Texas 
coast is focused on Galveston Bay. Of 31 oil refineries on the Texas coast, 12 (39 percent) are located 
in the four-county study area, representing 44 percent of the coastwide oil refinery design capacity 
(13). This is approximately 17 percent of the total oil refinery design capacity in the Gulf of Mexico. 
Of the 74 gas processing plants on the Texas coast, 22 (30 percent) are located in the four counties. 
Thirty-two percent of the gas processing plant design capacity along the Texas coast is located in the 
four county area (13). Of the 38 pipelines originating from either state or outer continental shelf (OCS) 
waters along the Texas coast, 16 (42 percent) make landfall in the four county area. The vast majority 
of pipelines from state waters make landfall in Brazoria County while the vast majority from OCS 
waters make landfall in Galveston County. Gas pipelines in these areas range in diameter from 6" to 
24," with oil pipelines being 4" to 14" in diameter (13).
