Dear John, 

This letter follows-up our telephone conversation of December 22, 1986 

and responds to your request for written correspondence. In that 

conversation, I indicated to you that EPA is actively considering the comments 

which you submitted to Ms. Dianne Byrne of EPA in your letter of 

August 14, 1986. In your letter, you suggested that the distribution of 

projected new industrial mixed fuel-fired (i.e., combination) boilers be 

shifted toward the southern U.S., namely, Regions IV and VI. You cited 

numbers for new combination boilers installed between 1980 and 1984 in Regions 

I, V, and X, but did not provide numbers for Regions IV and VI. We are 

requesting that you provide EPA with this information to guide the 

supplemental analyses that Radian Corporation is conducting under EPA's 

direction. In addition to the number of industrial combination boilers in 

Regions IV and VI, our analyses would be enhanced if you could also provide 

information on the distribution of these boilers with respect to heat input 

capacity (i.e., size) and the mixture proportions of wood and fossil fuels. 

On a separate but related subject, you are no doubt aware that EPA is 

currently evaluating PM, NO , and S02 standards for boilers with heat input 

capacities below 100 million Btu/hr, referred to as the Small Boiler standard. 

As with the Industrial Boiler standards, EPA will project the population of 

new boilers expected in the Small Boiler source category. Specifically, EPA 

will project the number and distribution of new small boilers to be installed 

in the 5-year period of 1989 through 1993. We are requesting at this time any 

data or information that you may have and are willing to share with EPA that 

would guide the Agency's projections for new wood-fired and combination small 

boilers expected to be installed in this time period. This information would 

include, but not be limited to, recent sales data or your own projections for 

new wood-fired and combination small boilers. In addition, any information or 

opinions you may have on recent trends and developments in this source 

category would be appreciated and considered.

'LATo be most useful, the requested Information for both Regions IV and VI 

Industrial boilers and small boilers should be transmitted directly either to 

Dianne Byrne at EPA or me at Radian by January 23, 1987. This can be done 

either by letter or by telephone with a follow-up letter. 

If you have any questions regarding these requests, please do not 

hesitate to call. I'd like to thank you in advance for your cooperation and 

interest in these matters. 

Yours very truly, 

Edward F. Aul, Jr., P.E.
