(i) Escanaba Paper, or any subsequent owner or operator of the 

Escanaba Paper facility in Escanaba, Michigan, shall meet the 

following requirements and shall not cause or permit the 

emission of oxides of nitrogen to exceed the following limits:

(1) For Boiler 8, designated as EU8B13, a rolling 30-day average 

limit of 0.35 pounds per million British Thermal Units 

(#/MMBTU). 

(2) A continuous emission monitoring system shall be operated to 

measure NOx emissions from Boiler 8 in conformance with 40 CFR 

60 appendix F.

(3) The reference test method for assessing compliance with the 

limit in paragraph (i)(1) shall be a continuous emission 

monitoring system operated in conformance with 40 CFR 60 

Appendix F. A new 30-day average shall be computed at the end 

of each calendar day in which the boiler operated, based on the 

following procedure: first, sum the total pounds of NOx emitted 

from the unit during the operating day and the previous twentynine operating days, second sum the total heat input to the unit 

in MMBTU during the same period, and third, divide the total 

number of pounds by the total heat input during the thirty 

operating days. 

(4) For Boiler 9, also identified as EU9B03, a limit of 0.27 

#/MMBTU.
(5) The reference test method for assessing compliance with the 

limit in paragraph (i)(4) shall be a test conducted in 

accordance with 40 CFR 60 appendix A Method 7.

(6) Recordkeeping. Owner/operator shall maintain the following 

records regarding Boiler 8 and Boiler 9 for at least five years:

(i) All CEMS data, including the date, place, and time of 

sampling or measurement; parameters sampled or measured; and 

results.

(ii) All stack test results.

(iii) Daily records of fuel usage, heat input, and data used to 

determine heat content.

(iv) Records of quality assurance and quality control activities 

for emissions measuring systems including, but not limited to, 

any records required by 40 CFR part 60, appendix F, Procedure 1.

(v) Records of all major maintenance activities conducted on 

emission units, air pollution control equipment, and CEMS.

(vi) Any other records identified in 40 CFR 60.49b(g) or 40 CFR 

part 60, Appendix F, Procedure 1.

(7) Reporting. All reports under this section shall be submitted 

to the Chief, Air Enforcement and Compliance Assurance Branch,

U.S. Environmental Protection Agency, Region 5, Mail Code AE17J, 77 W. Jackson Blvd., Chicago, IL 60604-3590.

(i) Owner/operator of Boiler 8 shall submit quarterly excess 

emissions reports for the limit in paragraph (i)(1) no later 
than the 30th day following the end of each calendar quarter. 

Excess emissions means emissions that exceed the emissions limit 

specified in paragraph (i)(1) of this section. The reports 

shall include the magnitude, date(s), and duration of each 

period of excess emissions, specific identification of each 

period of excess emissions that occurs during startups, 

shutdowns, and malfunctions of the unit, the nature and cause of 

any malfunction (if known), and the corrective action taken or 

preventative measures adopted.

(ii) Owner/operator of Boiler 8 shall submit quarterly CEMS 

performance reports, to include dates and duration of each 

period during which the CEMS was inoperative (except for zero 

and span adjustments and calibration checks or when Boiler 8 is 

not operating), reason(s) why the CEMS was inoperative and steps 

taken to prevent recurrence, and any CEMS repairs or 

adjustments.

(iii) Owner/operator of Boiler 8 shall also submit results of 

any CEMS performance tests required by 40 CFR part 60, appendix 

F, Procedure 1 (Relative Accuracy Test Audits, Relative Accuracy 

Audits, and Cylinder Gas Audits).

(iv) When no excess emissions have occurred or the CEMS has not 

been inoperative, repaired, or adjusted during the reporting 

period, such information shall be stated in the quarterly 

reports required by sections (i)(7) of this section.
(v) Owner/operator of Boiler 9 shall submit reports of any 

compliance test measuring NOx emissions from Boiler 9 within 60 

days of the last day of the test. If owner/operator commences 

operation of a continuous NOx emission monitoring system for 

Boiler 9, owner/operator shall submit reports for Boiler 9 as 

specified for Boiler 8 in paragraphs (i)(7)(i) to (i)(7)(iv).
