     If  Sulfur content Is In percent by weight on a dry basis.

     Tj  The larger number on each line refers to known resources.   This Includes both known recoverable reserves and known marginal and submarglnal
         resources.  It does not Include estimates of undiscovered  resources.

     37  The smaller number on each line is the Mitre estimate of known recoverable reserves alone; that which can be recovered with present technology
         and current prices.

     4/  Eastern Interior Is corrected.  Mitre figures are based  on J.A. DeCarlo, et_ al., Sulfur Content of United States Coals, Bureau of Mines,
         1C 8312 (1966), Table A-l, p.19.  This was altered by a  revision for the Illinois data in which the reserve estimates for low sulfur coal
         were modified.  See U.S. Department of Health, Education and Welfare, Control Techniques for Sulfur Oxide Air Pollutants, NAPCA No. AP-52
         (January 1969), table 4-2, pp. A-ll.

     Regions:  Northern Appalachia is defined  as Pennsylvania, the  northern part of West Virginia and Maryland.  The southern Appalachian region is
               composed of eastern Kentucky, the southern part of West Virginia, Tennessee, Virginia and Alabama.  The eastern Interior region is made
               up of Illinois, Indiana, western Kentucky, and Ohio.  The western Interior region is composed of Iowa, Kansas, Missouri, Oklahoma,
               Arkansas and Texas.  The northern Rocky Mountains  region is made up of North and South Dakota,  Montana, Wyoming and Idaho.  The southern
               Rocky Mountains region comprises Colorado, Utah, Arizona and New Mexico.  Finally, the West Coast includes Washington, Oregon and
               California; it excludes Alaska.

(1)  To avoid the rounded range gaps found in DeCarlo and succeeding publications
     (i.e., 1.0-1.1), differences have been halved to eliminate the gap.  Figures
     in parentheses are the mid-point of the ranges with the exception of the
     first (0.65) which was assumed for computational purposes.  In the body of
     the table, figures in the parentheses refer to the implied average sulfur
     level of the tonnages in each class.

(2)  Weighted average of 21,370 known reserves and 2,780 known recoverable
     reserves at 1.08 percent plus 23,050 known reserves and 2,995 known recoverable
     reserves at 1.50 percent.

(3)  Weighted average of 18,135 known reserves and 1,995 known recoverable reserves
     at 1.08 percent plus 9,890 known reserves and 1,090 known recoverable reserves
     at 1.50 percent.

(4)  Weighted average of 3,780 known reserves and 340 known recoverable reserves
     at 0.76 percent plus 585 known reserves and 50 known recoverable reserves
     at 1.05 percent.

(5)  Weighted average of 344,620 known reserves and 37,905 known recoverable
     reserves at 1.08 percent plus 61,385 known reserves and 6,750 known
     recoverable reserves at 1.5 percent.

      1)  The above  estimates  assume  recovery of 40 percent of the underground, and 70 percent
          the surface, reserve base  (measured and indicated deposits within 1000 feet of  the
          surface with seam  thickness of  at least 28 inches for bituminous and anthracite and
          at least .60 inches for  sub-bituminous and lignite).

      2)  Northern Plains reserves shown  are strippable only - deeper reserves are excluded.

      3)  No more than 1.2 pounds sulfur  dioxide per million BTy.

      4)  1.21 - 3.20 pounds S02  per  million BTU.

1The standard thickness  divisions are 14-28,  28-42, and >42 inches for bituminous coal and anthracite, and
   30-60, 60-120, and >120 inches for subbitumlnous coal and lignite.
sThe standard depth divisions are 0-1,000,  1,000-2,000, and 2,000-3,000 feet.
3Potential refers to coal  under a 400 square-mile are estimated from one or more measurements.
*Depth-thickness criteria  are 16 Inches at  100 feet, 18 inches at 150 feet, 22 inches at 200 feet, 32 inches
   at 600 feet, and 36 inches at 1,200 feet.
5Data for anthracite and bituminous coal are  also reported on an inferred rone basis with various thickness
   divisions and depth divisions of 1,000-2,000 or 0-3,000 feet.
BDepth Is not always reported, and sone divisions are 0-2,000 or 0-3,000 feet.
