CLASS VI OPERATING AND REPORTING CONDITIONS

Facility Name: FutureGen 2.0 Morgan County CO 2 Storage Site

IL -137-6A-0004 (W ell #4)

Facility Contacts: Kenneth Humphreys, Chief Executive Officer,

FutureGen Industrial Alliance, Inc., Morgan County Office, 73 Central Park Plaza East, Jacksonville, IL 62650, 217-243-8215

L ocation of Injection Well: Morgan County, IL; 26−16N−9W; 39.80111oN and 90.07544oW

In jection Well Operating Conditions:

PARAM ETER/CONDITION LIMITATION or PERMITTED

VALUE UNIT

Maximum Injection Pressure

Surface 1,171 psig

Downhole 2,237 psig

Annulus Pressure 100 minimum psig Annulus Pressure/Tubing Differential 100 above surface injection pressure psig

The downhole gauge for injection pressure monitoring is located at: 3,850 feet below ground surface.

The maximum injection pressure, which serves to prevent confining-formation fracturing, was determined using the following formula/methodology:

 For maximum injection pressure using a downhole pressure gauge, the maximum pressure is calculated as follows: 90% of fracture pressure of the injection zone. Therefore, the maximum injection pressure using downhole pressure gauge is 2,252 psia or 2,252-14.7 = 2,237 psig

.

 For surface maximum wellhead injection pressure , this limitation was calculated using the following formula: [{90% of fracture gradient-(0.433psi/ft)(specific gravity)} X upper depth of perforated interval ] - atmospheric pressure. The maximum wellhead injection pressure is: [{0.585-(0.433)(0.64 )}3850] -14.7 = 1,171psig

.

If the downhole pressure gauge fails to function properly, then the maximum injection pressure shall immediately be limited to the calculated surface pressure until the downhole pressure gauge is repaired or replaced.

Shutdown Procedure:

The permittee has not developed procedures for implementing a gradual well shutdown.Summary of Requirements for FutureGen Alliance

Permit Number: IL- 137
