2004 Part 70 Permit

appropriate national response agency, and to the Tennessee Emergency

Management Agency. 

§4-12 and §4-57(a)(3)(iii)(B)

13.0. Emergency Provision. 

13.1. Definition. An emergency is any situation arising from sudden and reasonably

unforeseeable events beyond the control of the permittee, including acts of God, 

which situation requires immediate corrective action to restore normal operation, 

and that causes the permittee to exceed a technology-based emission limitation 

under the permit, due to unavoidable increases in emissions attributable to the 

emergency. An emergency shall not include noncompliance to the extent caused 

by improperly designed equipment, lack of preventative maintenance, careless or 

improper operation, or operator error. §4-57(g)

13.2. An emergency constitutes an affirmative defense to an action brought for 

noncompliance with such technology-based emission limitations if the conditions 

of Item 13 of these Conditions of General Applicability are met, unless an 

ambient air violation occurs as a result of the emergency. The affirmative defense 

of emergency shall be demonstrated through properly signed, contemporaneous 

operating logs, or other relevant evidence which establishes that: 

13.2.1. An emergency occurred and that the permittee can identify the cause(s) of 

the emergency; and

13.2.2. The permitted facility was at the time being properly operated; and

13.2.3. During the period of the emergency the permittee took all reasonable steps 

to minimize levels of emissions that exceeded the emission standards, or 

other requirements in the permit; and

13.2.4. The permittee submitted telephone notice of the emergency to the Bureau 

Director within one (1) working day of the time when emission limitations 

were exceeded due to the emergency, and the permittee submitted a follow 

up written report to the Bureau within seven (7) days after the onset of the 

exceedance. This notice must contain a description of the emergency, any

steps taken to mitigate emissions, and corrective actions taken. §4-57(g)

13.3. In any enforcement proceeding, the permittee seeking to establish the occurrence 

of an emergency has the burden of proof. §4-12; 4-57(g) 

13.4. The permittee must employ all reasonable measures to keep emissions to a 

minimum during start-ups, shutdowns, operation, and emergencies. These 

measures may include installation and use of alternate control systems, changes in 

operating methods or procedures, cessation of operation until the process 

equipment or air pollution control equipment is repaired, maintaining sufficient 

spare parts, use of overtime labor, use of outside consultants and contractors, and 

other appropriate means. Exceedances of limitations on emissions that are caused 

by poor maintenance, careless operation, or any other preventable upset condition 
Signal Mountain Cement Company, L.P Page 8 of 27

2004 Part 70 Permit

or preventable equipment breakdown shall not be considered emergencies, and 

shall be considered in violation of the emission standard exceeded. §4-12

13.5. A log of any operation or failure to operate, start-up, or shutdown resulting in air 

pollutant emissions in excess of any applicable requirement must be kept at the 

Part 70 source. This log must record at least the following:

13.5.1. Stack, air pollution control equipment, or emission point involved;

13.5.2. Time excess emissions, start-up, or shutdown began or when excess 

emissions were first discovered by the source;

13.5.3. Type of exceedance qualifying as a malfunction, or reason for shutdown;

13.5.4. Time start-up or shutdown was complete or time the air pollutant source 

returned to normal operation after an emissions exceedance;

13.5.5. Documentation that the source was or was not, at the time of the onset of 

the exceedance, being properly operated;

13.5.6. Documentation of any preventative maintenance of the air pollution 

control equipment or process equipment or processes that had been 

completed prior to the emissions exceedance, start-up, or shutdown;

13.5.7. The steps taken by the source during the period of the emissions 

exceedance, start-up, or shutdown to minimize levels of emissions that 

exceeded the applicable requirements; and

13.5.8. The magnitude and identity of the excess emissions, expressed in pounds 

per hour and the units of the applicable emission limitation, and the 

operating data and calculations used in determining the magnitude of the 

excess emissions. §4-12

13.6. The information required by Items 13.5.1 and 13.5.2 of these Conditions of 

General Applicability must be entered into the log by the end of the shift during 

which the exceedance or other deviation began. All required information shall be 

entered in the log no later than 24 hours after the exceedance or other deviation 

has ceased or has been corrected. Any later discovered corrections may be added 

in the log as footnotes with the reason given for the change. There shall be no 

erasures, obliterations, modifications, or revisions of the log entry except by single

line-through and identification of corrections. §4-12

13.7. If the Bureau Director or the Administrator of the Chattanooga-Hamilton County

Health Department finds that a condition of air pollution exists or is likely to 

exist, and that it creates any emergency requiring immediate action to protect 

human health or safety, the mayor with the concurrence of the Bureau Director or 

the Administrator of the Chattanooga-Hamilton County Health Department shall 

order persons causing or contributing to the air pollution to reduce or discontinue 

immediately the emission of air pollutants. Upon issuance of any such order, the 

Bureau Director shall fix a place and time, not later than twenty-four (24) hours 
Signal Mountain Cement Company, L.P Page 9 of 27

(24) hours after commencement of such hearing, and without adjournment 

thereafter, the Board shall affirm, modify, or recommend to the mayor that the 

order be affirmed, modified or set aside. §4-20

14.0. Certification. Any application form, report, or compliance certification submitted 

pursuant to this permit shall contain a certification, as defined in §4-53, by a responsible 

official, as defined in §4-53, of truth, accuracy, and completeness. Any certification 

required by this permit shall state that based on information and belief formed after 

reasonable inquiry, the statements and information in the document are true, accurate, and 

complete. §4-56(d)

15.0. Modifications.

15.1. Administrative amendments to this permit shall be requested and may be granted 

in accordance with §4-58(d), and only for the reasons set forth therein. The

with the Tennessee Secretary of State. 

15.2. Minor permit modifications to this permit shall be requested and may be granted 

in accordance with §4-58(e)(1) and (2).

15.3. Significant permit modifications to this permit shall be requested and may be 

granted in accordance with §4-58(e)(3). 

15.4. Operational flexibility allows changes within this permitted source without 

requiring a permit revision, if the changes are not modifications under Title I of 

the Clean Air Act and the changes do not exceed the emissions allowable under 

this permit (whether expressed herein as a rate of emissions or in terms of total 

emissions), provided that:

15.4.1. The permittee provides the U.S. Environmental Protection Agency and the 

Bureau Director with written notification at least 7 days in advance of the 

proposed changes; and
