### Fuel Restrictions: A. EU BF-5101 (Riley Boilers A, B & S) andBF-5002 (Superheaters A & B) shall be operated using only waste gas, fuel gas, tar oil, naphtha, phenol, substitute natural gas (SNG), or other lignite-derived fuels. Substitute fuels may be used for tar oil ifanalytical lab analysis shows the substitute fuel is less than or equal to tar oil inthe content ofash, sulfur and nitrogenper Btu.Applicable Requirement: Permitto Construct (PTC) 10027**Page~** of 49 PTO No. T5-F96007

Fuels and feedstock, other than those listed above, may be burned or charged provided the following conditions are met: Acceptable gasification feedstock shall meet the recycling criteria established in Section 33-24-02-02(5)(a) ofthe NDAC and must not be a listed hazardous waste. The Department shall approve in writing all initial feedstock usage. Any change in feedstock which will significantly increase emissions as defined in the Prevention of Significant Deterioration (PSD) rules shall require Departmental approval. Applicable Requirement: PTC Cond. 4. Miscellaneous Conditions: A. Production Rate: For purposes ofthis permit and the PSD rules, an increase in production rate above 170 million standardcubic feet perday (based ona 12-monthcalendaraverage) that causes a significant increase in actual emissions is considered a major modification. Applicable Requirement: PTC 3/23/93 B. Like-Kind Engine Replacement: This permit allows the permittee to replace the existing engines with like-kind engines. Replacement is subject to the following conditions:
