Instructions for

Opt-in Permit Application (40 CFR 74.16)

The designated representative of a combustion source that seeks to participate in the Opt-in Program is required to submit 

an opt-in permit application. The opt-in permit application gives EPA necessary information about the combustion source, 

such as its location, operating history, and emissions data.

Please type or print. The alternate designated representative may sign in lieu of the designated representative. For 

assistance, call the Acid Rain Hotline at (202) 233-9620. Enter the plant name from Step 1, the combustion source ID 

number from Step 2, and the date in the boxes provided on each page.

STEP 1 NADB is the National Allowance Data Base for the Acid Rain Program. To obtain the database on diskette, call 

the Acid Rain Hotline at (202) 233-9620. This data file is in dBase format for use on an IBM-compatible PC. It 

requires approximately 2 megabytes of hard disk space.

If the combustion source does not have an ORIS code, use the code from the Department of Energy 867 form. 

If no 867 form has been filed for the combustion source, leave this space blank, and EPA will assign a code.

STEP 2 The combustion source ID number and the combustion source short name are the ID number and name 

assigned by the operator to distinguish this combustion source from others at the facility.

STEP 3 Enter the latitude and longitude if they are known. If not, leave blank.

Enter the plant mailing address if it is different from the plant site address.

STEP 4 If the combustion source has participated in the Opt-in Program prior to submitting the current application, the 

combustion source may not submit a new opt-in permit application until four years after the effective date of its 

most recent opt-in permit. The opt-in permit's effective date is defined under 40 CFR 74.14(d)(1). This 

restriction does not affect participating opt-in sources when renewing their opt-in permits.

STEP 5 Briefly describe the combustion source for which the opt-in permit application is being submitted and the 

facility where the combustion source is located.

Example:

General Facility Description: Paper mill

Combustion Source Description: Boiler supplying steam to pulping process.

Attach a diagram showing the general layout of the facility and the location of the combustion source within the 

facility.

STEP 6 Check the first box if the combustion source uses a scrubber to control SO2 emissions. If the combustion 

source uses other SO2 control methods, check the second box and identify the method in the space provided. 

If the combustion source does not use controls for SO2 emissions, check the third box.

STEP 7 The combustion source must submit two copies of a complete monitoring plan with the opt-in permit 

application.

Check the second box or the third box to indicate when the Certificate of Representation for the combustion 

source was submitted. The Certificate of Representation must be submitted prior to or at the same time as the 

opt-in permit application.

STEP 8 Each combustion source must hold sufficient allowances to cover its emissions of SO2 as required in 40 CFR 

72.9(c)(1).

If the combustion source seeks to transfer allowances to a replacement unit or units for the replacement of 

thermal energy under 40 CFR 74.47, check the second box and submit a Thermal Energy Plan form.
Page 2 Opt-in Permit Application Instructions

STEP 9 Enter the month and year that the combustion source commenced operation.

Enter the number of hours that the combustion source operated during the six months preceding the application, the dates 

for this six month period, and indicate that data supporting the determination of the number of operating hours are 

attached. You may submit this data in ASCII format on a 3 1/2 inch high density floppy disk. If so, provide the file name 

and a complete description of the data layout of the file.

STEP 10 If the combustion source began operating before January 1, 1985, use data from 1985, 1986 and 1987 to determine the 

baseline utilization. Check the top box.

If the combustion sources began operating after January 1, 1985, or if the data required for determining the baseline 

utilization of the combustion source are not available due solely to a natural catastrophe, use data from the first three 

consecutive calendar years after December 31,1985, when the combustion source operated. Check the appropriate box 

and enter the first year for which data are used.

STEP 11 For each type of fuel used at the combustion source, complete and attach one Opt-in Permit Application Worksheet. Enter 

the number of worksheets attached in the box in Step 11.

STEP 12 Check the box next to each type of fuel combusted by the combustion source to indicate that a worksheet for that fuel is 

attached. If a fuel type used at the combustion source is not listed, check the "Other" box at the bottom of the table, and 

identify the fuel in the space provided. 

Enter the total 1985 (or first year) fuel consumption, average annual fuel consumption, and SO2 emissions for 1985 (or 

first year) from the bottom of the worksheet for each fuel type.

STEP 13 Total the 1985 (or first year) fuel consumption amounts listed in Step 12, and enter the result in box (a).

Total the average annual fuel consumption amounts listed in Step 12, and enter the result in box (b). This is the baseline 

utilization.

Total the SO2 emissions for 1985 (or first year) listed in Step 12, and enter the result in box (c).

STEP 14 Enter the total SO2 emissions for 1985 (or first year) from box (c) of Step 13. Divide it by the total 1985 (or first year) fuel 

consumption from box (a) of Step 13. The result is the actual 1985 (or first year) SO2 emissions rate.

STEPS 15,

16 and 17

In Steps 15, 16 and 17, enter the three federally enforceable SO2 emissions limits used to calculate the allowance 

allocation. These limits are (1) the 1985 allowable SO2 emissions rate; (2) the current allowable SO2 emissions rate; and 

(3) the current promulgated SO2 emissions limit. Please refer to 40 CFR 72.2, 74.23, 74.24 and 74.25 for additional 

descriptions of these limits.

If the regulatory limit is not measured in Ibs/mmBtu, use the appropriate conversion factor from the table below.

PART II - TABLE INFORMATION

Operating Year. If the combustion source began operating before January 1, 1985, enter data from 1985, 1986 and 1987. If 

the combustion source began operating after January 1, 1985, or if the data required on the worksheet are not available due 

solely to a natural catastrophe, use data from the first three consecutive calendar years after December 31, 1985, when the 

combustion source operated and for which data are available. Enter the operating years for which data are used in the 

spaces at the top of the table.

Quantity, Sulfur Content (%S), and Heat Content. This information may be submitted on a monthly or annual basis.

Fuel Consumption. This information may be submitted on a monthly or annual basis. For each month and/or each year, 

determine the fuel consumption using the following formula:

Fuel Consumption = ( quantity of fuel 

consumed ) x (heat content) x (unit conversion)

If submitting monthly data, total the monthly fuel consumption amounts to determine the annual fuel consumption.

The unit conversion for several types of fuel is listed in the following chart:

Fuel Type Unit Conversion

Coal 2

Oil 0.001

Natural Gas 1

Other Combustion source must specify

If the fuel type for this worksheet is not listed, the combustion source must specify the unit conversion in the calculation. 

Enter the annual fuel consumption for each year in the space on the bottom row of the table, and attach to the worksheet the 

annual fuel consumption calculation for each of the three operating years for which data are submitted.
