4-inch crude oil and condensate pipeline from the new Mobil-David field south
of Corpus Christi to the Suntide refinery at Corpus Christi. A 4-mile, 4-inch
crude oil pipeline connecting the Frost and Carbondale oilfields in Cass
County with the company's Bryans Mill processing plant was begun by Shell
Pipe Line Corp. Design capacity was estimated at 3,500 barrels daily. Black
Lake Pipe Line Co., jointly owned by Sinclair Oil Corp. and Placid Oil Co.,
completed a 192-mile, 8-inch crude oil and gas liquids line to Sinclair's
Houston refinery from the Black Lake oilfield near Natchitoches, La. 
 Two major pipelines to carry ammonia from Texas to midwestern markets were
planned by Mid-America Pipeline Co. and by Gulf Central Pipeline Co. Mid-America
will build an 850-mile line from Borger, Tex., to northwestern Iowa. The
line will deliver ammonia from the 1,000-ton-perday plant that Hill Chemical's,
Inc., was building at Borger to Iowa for fertilizer markets. Gulf Central
Pipeline Co. planned a $65 million, 2,000-mile ammonia transmission system
from gulf coast ammonia producers to midwest fertilizer markets. The proposed
system will' include a 10-inch trunk line from a gulf coast location to a
northern Missouri location with laterals to gulf coast ammonia plants and
to ammonia-consuming areas in Illinois, Indiana, Iowa, and Nebraska. Initial
pipeline capacity was estimated at 1.5 million tons per year with construction
to begin early in 1969. The first pipeline to deliver industrial gas from
a production facility to a consumer was under contract by Air Products &
Chemicals, Inc. A major chemical company contracted with Air Products to
receive hydrogen gas by pipeline directly from a new industrial gas facility
that Air Products was building in Houston. Nitrogen and argon will also be
produced for gulf coast markets at the Houston facility. 
 
NONMETALS 
 
 The nonmetallic mineral industry of Texas registered new gains. Total value
of output was up 10 percent, and accounted for 8 percent of the State's total
1967 mineral production value. Record highs were set in the production of
portland cement, lime, salt, and combined stoneshell, reflecting the increased
demand by construction, chemical, and other industrial 
users. Production was up during the year for ethylene dibromide, miscellaneous
clay, bail clay, kaolin, fuller's earth, gypsum, magnesium chloride, sand
and gravel, basalt, dimension granite, crushed marble, dimension and crushed
sandstone, crushed limestone, crushed marl, shell, and sulfur. Declines were
noted in production of fire clay, bentonite graphite, magnesium compounds,
natural sodium sulfate, perlite, crushed granite, miscellaneous stone, dimension
limestone, talc, and pumicite. New production reported in 1967 included crude
vermiculite and dimension marble. 
 
 Barite.—No production of crude barite was reported—the open-pit
barite mine in the Seven Heart Gap area of Culberson County was fnactive
during the year. Crude barite, mined outside of Texas, was processed at the
Brownsville plant of Dresser Minerals Division of Dresser Industries, Inc.;
at the Corpus Christi and Houston plants of Baroid Division of National Lead
Co.; and at the Houston plant of Milwhite Co., Inc. Output of the ground
barite declined 25 percent during 1967. 
 
 Bromine.—Texas continued as the Nation's second largest producer of
bromine. Elemental bromine was extracted from sea water at the Freeport plant
of Ethyl-Dow Chemical Co. on the Gulf Coast. Most of the output was consumed
in production of ethylene dibromide, used chiefly as an additive in antiknock
compounds in leaded gasolines. Total output and value of ethylene dibromide
were up slightly from 1966 levels. 
 
 Cement.—The portland cement industry in Texas attained record highs
in production, shipments, and total value. The increases followed a rise
in construction activity in the State during the year. Production of portland
cement was up about 3 percent from that of 1966. Shipments from plants in
Texas, which accounted for approximately 9 percent of the Nation's total,
were up almost 4 percent. Slightly more than 77 percent of the portland cement
shipments were moved by truck, 21 percent by rail, and 1 percent by water.

 Thirteen companies operated the State's 19 cement plants, located in Bexar,
Dallas, Ector, Ellis, El Paso, Harris, McLennan, Nolan, Nueces, Orange, Potter,
and Tarrant Counties. The 49 kilns at the plants
