GENERAL CONDITIONS

1. The process or process equipment covered by this permit shall not be reconstructed, relocated, or modified, unless a Permit to Install authorizing such action is issued by the Department, except to the extent such action is exempt from the Permit to Instal l requirements by any applicable rule. ( R 336 .1201(1))

2. If the installation, construction, reconstruction, relocation, or modification of the equipment for which this permit has been approved has not commenced within 18 months, or has been interrupted for 18 months, this permit shall become void unless otherwise authorized by the Department. Furthermore, the permittee or the designated authorized agent shall notify the Department via the Supervisor, Permit Section, Air Quality Division, Michigan Depart ment of Environmental Quality , P.O. Box 30260, Lansing, Michigan 48909

- 7760 , if it is decided not to pursue the installation, construction, reconstruction, relocation, or modification of the equipment allowed by this Permit to Install. ( R 336 .1201(4))

3. If this Permit to Install is issued for a process or process equipment located at a stationary source that is not subject to the Renewable Operating Permit program requirements pursuant to R 336 .1210, operation of the process or process equipment is allow ed by this permit if the equipment performs in accordance with

the terms and conditions of this Permit to Install. ( R 336 .1201(6)(b))

4. The Department may, after notice and opportunity for a hearing, revoke this Permit to Install if evidence

indicates the process or process equipment is not performing in accordance with the terms and conditions of this permit or is violating the Department ’ s rules or the Clean Air Act. ( R 336 .1201(8), Section 5510 of Act 451, PA 1994)

5. The terms and conditions of th is Permit to Install shall apply to any person or legal entity that now or hereafter owns or operates the process or process equipment at the location authorized by this Permit to Install. If the new owner or operator submits a written request to the Depa rtment pursuant to R 336.1219 and the Department approves the request, this permit will be amended to reflect the change of ownership or operational control. The request must include all of the information required by subrules (1)(a), (b), and (c) of R 33 6.1219 and shall be sent to the District Supervisor, Air Quality Division, Michigan Department of Environmental Quality

. (R 336.1219)

6. Operation of this equipment shall not result in the emission of an air contaminant which causes injurious effects to human health or safety, animal life, plant life of significant economic value, or property, or which

causes unreasonable interference with the comfortable enjoyment of life and property. (R 336.1901)

7. The permittee shall provide notice of an abnormal condition, start

- up, shutdown, or malfunction that results in emissions of a hazardous or toxic air pollutant which continue for more than o ne hour in excess of any applicable standard or limitation, or emissions of any air contaminant continuing for more than two hours in excess of an applicable standard or limitation, as required in Rule 912, to the Department. The notice shall be provided not later than two business days after start

- up, shutdown, or discovery of the abnormal condition or malfunction. Written reports, if required, must be filed with the Department within 10 days after the start

up or shutdown occurred, within 10 days after the abnormal conditions or malfunction has been corrected, or within 30 days of discovery of the abnormal condition or malfunction, whichever is first. The written reports shall include all of the information required in Rule 912(5). ( R 336 .1912)

8. App roval of this permit does not exempt the permittee from complying with any future applicable requirements which may be promulgated under Part 55 of 1994 PA 451, as amended or the Federal Clean

Air Act.

9. Approval of this permit does not obviate the neces sity of obtaining such permits or approvals from other units of government as required by law.

10. Operation of this equipment may be subject to other requirements of Part 55 of 1994 PA 451, as amended and the rules promulgated thereunder.DTE Energy , Monroe Power Plant (B2816) September 4 , 2013

11. Except as provided in subrules (2) and (3) or unless the special conditions of the Permit to Install include an alternate opacity limit established pursuant to subrule (4) of R 336 .1301, the permittee shall not cause or permit to be discharged into the out er air from a process or process equipment a visible emission of density greater than the most stringent of the following. The grading of visible emissions shall be determined

in accordance with R 336 .1303. ( R 336 .1301) a) A six

- minute average of 20 per cent opacity, except for one six

- minute average per hour of not more than 27 percent opacity. b) A visible emission limit specified by an applicable federal new source performance standard. c) A visible emission limit specified as a condition of this Permit to Install.

12. Collected air contaminants shall be removed as necessary to maintain the equipment at the required operating efficiency. The collection and disposal of air contaminants shall be performed in a manner so as

to minimize the introduct ion of contaminants to the outer air. Transport of collected air contaminants in Priority I and II areas requires the use of material handling methods specified in R 336 .1370(2). ( R 336 .1370)

13. The Department may require the permittee to conduct accep table performance tests, at the permittee ’ s expense, in accordance with R 336 .2001 and R 336 .2003, under any of the conditions listed in R 336 .2001. ( R 336 .2001)DTE Energy , Monroe Power Plant (B2816) September 4 , 2013

a. Exceedences of the yearly actual emission of PM2.5 and SO 2 above the baseline actual emissions (BAE) by a significant amount, and

b. Identify if the year’s actual emissions differ from the pre

- construction projection. The pre

- construction projection is the sum of the projected actual emissions from each existing emission unit and the potential emissions from each new emission unit included in the Hybrid Applicability Test used for

FG

- ProjectPC1
