million man-hours compared with nearly 14.3 million man-hours in 1966. Only
four fatalities were recorded compared with 12 the previous year. Of the
four fatalities, three were at underground mines causcd by fails of roof
and the other was at a strip mine. The number of nonfatal injuries totaled
375. The State's fatal injury rates of 0.26 per million man-hours and 0.09
per million short tons were the lowest in the Nation and were well below
the national averages of 0.90 and 0.38, respectively. In National Safety
Competition, the Crescent Valley No. 7 mine of Hanna Coal Co., Division of
Consolidation Coal Co., was the winner of the surface group competition and
was awarded a trophy for having the best safety record of the year. The mine
worked 218,255 man-hours without any disabling injuries. Also in the same
competition, three other mines of the company (West Farm No. 22, Bradford
No. 16, and Georgetown No. 24) as well as Magnolia Mining Co. (Mapleton mine),
Belville Mining Co., Inc. (strip mine), and Mineral Transport, Inc. (Mineral
Patterson mine), were awarded Certificates of Achievement in Safety for working
without any disabling injuries. In National Safety Competition for underground
coal mines, the Coshocton mine of Mason & Sons Coal Co., Inc., and the
Low Ash No. 2 mine of Monroe Coal Co. also were given Certificates of Achievement
for their safety records. 
 
 Coke and Coal Chemicals.—Production 
of oven-coke decreased 5 percent below that of 1965 and totaled 8.1 million
tons valued at $139 million. 
 
 Peat.—Shipments and value were greater than that of 1966, but the
average value per ton decreased from $16.19 to $13.68. The increase was attributed
primarily to more active operations. Prices declined as operators reported
more lower-priced bulk sales. Output was from 11 counties; Stark County with
four operations ranked first in tonnage. Of the total sales, 40 percent was
moss peat, 32 percent humus, and 28 percent was reed-sedge peat. Most of
the peat was sold in bulk and used chiefly for soil conditioning. 
 
 Petroleum and National Gas.—Producti()n and value of both petroleum
and natural gas declined compared with that of 1966. According to the American
Associa 
tion of Petroleum Geologists, total well completions declined from 1,312
to 1,261 but total footage drilled increased from 3,733,000 to 4,088,000.
A total of 1,179 development and 82 wildcat completions were reported. Development
wells were drilled in 42 counties; Stark, Perry, Licking, and Morgan Counties
were the leading areas. Wildcat completions were reported in 34 counties;
Huron and Stark Counties with eight wells each were the leading areas for
wildcat activity. The number of wildcat completions dropped from 138 in 1966
to 82. Most drilling operators in Ohio used cable tool equipment. According
to the Division of Oil & Gas, Ohio Department of Natural Resources, 14,638
petroleum wells were productive at the end of 1967. 
 Reserves on December 31, 1967, were 762,731 million cubic feet of natural
gas (14.73 pounds per square inch absolute, at 60°F), and 92.1 million
barrels of crude petroleum, according to the Amen-, can Gas Association and
American Petroleum Institute. Compared with the end of 1966, reserves of
natural gas increased by 
7,516 million cubic feet but crude petroleum reserves decreased by 9.1 million
barrels. According to a survey, three companies operated natural gas storage
facilities having total capacity of 407,075 million cubic feet. Operators
of natural gas storage areas were East Ohio Gas Co. (four areas), Manufacturers
Light & Heat (one area), and Ohio Fuel Gas Co. (14 areas) .~ Permian
Corp. operated its Edison natural gas processing plant in Morrow County.
Propane, butane, and LP-gas mix were recovered by the refrigeration-absorption
process at the plant which formerly was operated by McWood Corp. 
 Nine petroleum refineries were active: 
total crude oil capacity as of January 1, 1967, was 460,700 barrels per day,
3,500 barrels less than in 1966. Gasoline output capacity totaled 221,605
barrels per day compared with 187,000 barrels the previous year. Other products
recovered at the refinery included asphalt, coke, lubricant, and paraffin.
For recovering gasoline and other products companies used catalytic and thermal
cracking and reforming, hydrocracking, coking, and alkylation processes.
Refineries were operated at Canton,
