facilities, and other process and service facilities. Employment was about
1,400 people, and operating costs were about $24 million per year. 
 A report was published that discussed producing alumina by a seldom-used
process, with special modifications to treat the iron-bearing bauxites of
Oregon and Washington.3 
 Exploration and development of mineral deposits in the State were conducted
by 23 companies. A directory was published by the Washington State Department
of Conservation that lists the firms and also shows locations of both metallic
and nonmetallic minerals operations and the 1965 mineral production by county.4

 Sales of electric energy by the Bonneville Power Administration (BPA) to
aluminum reduction and rolling plants in Washington increased nearly 24 percent
compared with 1966 sales; total revenue generated by these sales amounted
to $23.5 million. Electric energy production for the State's domestic needs
rose by 13 percent in 1967 from the prior year to reach 60.4 billion kilowatt-hours.

 Economic Activity and Employment.— Washington experienced a rate of
economic growth greater than that of any postwar year, excepting 1966 and
1951. Continued economic strength was indicated for the State by measuring
the significant gains recorded in several important indicators of business
activity. Although the 1966—67 gain in total personal income of 9.7
per. cent did not equal that for the period 1965—66 (13.1 percent),
it still exceeded the U.S. average of 6.9 percent and the Western States
average of 7.9 percent. Per capita personal income increased 8.0 percent
for the State compared with 5.9 percent for the Nation. According to the
Federal Reserve member bank report, bank loans rose 8.1 percent in the State,
compared with 6.2 percent nationally. Residental construction starts were
up 60
