AIR QUALITY CLASS I PERMIT 

COMPANY: Chemical Lime Company, Nelson Lime Plant 

FACILITY: Nelson Lime Plant 

PERMIT #: 

DATE ISSUED: August 8, 2011 

DATE EXPIRES: August 8, 2016 

SUMMARY 

This Class I permit is issued to Chemical Lime Company/Nelson Lime Plant, the Permittee, for operation 

of its limestone processing and lime manufacturing plant located approximately six miles east of Peach 

Springs in Yavapai County, Arizona. The limestone processing operation consists of a quarry area, a 

crushing and screening plant, and auxiliary operations. The lime manufacturing operation consists of prekiln limestone handling, two lime kilns, post-kiln lime handling, a hydrator, two peak demand generators, 

truck and rail loadout facilities, and solid fuel handling. Air pollution control equipment applied at the 

Nelson Lime Plant includes a number of baghouses, two multicyclone dust collectors, and a Ducon wet 

scrubber to control particulate matter emissions. 

This permit is issued in accordance with Title 49, Chapter 3 of the Arizona Revised Statutes. All 

definitions, terms, and conditions used in this permit conform to those in the Arizona Administrative 

Code R18-2-101 et. seq. (A.A.C.) and 40 Code of Federal Regulations (CFR), except as otherwise 

defined in this permit. All terms and conditions in this permit are enforceable by the Administrator of the 

U.S. Environmental Protection Agency except as otherwise provided in this Permit. 

The potential to emit of the following pollutants are greater than major source thresholds: (i) particulate 

matter with an aerodynamic diameter less than 10 microns (PM10), (ii) sulfur dioxide (SO2), (iii) nitrogen 

oxides (NOx), and (iv) carbon monoxide (CO). Additionally, the potential to emit of hydrogen chloride 

(HCl) also exceeds the major hazardous air pollutant threshold. Therefore, the facility is classified as a 

major source as defined in A.A.C. R18-2-101(64), and requires a Class I permit pursuant to A.A.C. R18-

302(B)(1)(a).

TERMINATION FOR CAUSE 

[A.A.C. R18-2-306.A.8.c; A.A.C. R18-2-321.A.1.c; A.A.C. R18-2-321.A.1.d; A.A.C. R18-2-321.A.2] 

A. The permit may be revised, reopened, revoked and reissued, or terminated for cause. The 

filing of a request by the Permittee for a permit revision, revocation and reissuance, 

termination, or of a notification of planned changes or anticipated noncompliance does 

not stay any permit condition. 

B. The permit shall be reopened and revised under any of the following circumstances: 

1. Additional applicable requirements under the Clean Air Act become applicable to 

the Class I source. Such a reopening shall only occur if there are three or more 

years remaining in the permit term. The reopening shall be completed no later 

than 18 months after promulgation of the applicable requirement. No such 

reopening is required if the effective date of the requirement is later than the date 

on which the permit is due to expire, unless an application for renewal has been 

submitted pursuant to A.A.C. R18-2-322.B. Any permit revision required 

pursuant to this subparagraph shall comply with the provisions in A.A.C. R18-2-

322 for permit renewal and shall reset the five-year permit term. 

2. Additional requirements, including excess emissions requirements, become 

applicable to an affected source under the acid rain program. Upon approval by 

the Administrator, excess emissions offset plans shall be deemed to be 

incorporated into the Class I permit. 
Permit No. 42782 Page 4 of 81 

3. The Director or the Administrator determines that the permit contains a material 

mistake or that inaccurate statements were made in establishing the emissions 

standards or other terms or conditions of the permit. 

4. The Director or the Administrator determines that the permit needs to be revised 

or revoked to assure compliance with the applicable requirements. 

C. Proceedings to reopen and reissue a permit, including appeal of any final action relating 

to a permit reopening, shall follow the same procedures as apply to initial permit issuance 

and shall, except for reopenings under Condition III.B.1 above, affect only those parts of 

the permit for which cause to reopen exists. Such reopenings shall be made as 

expeditiously as practicable. Permit reopenings for reasons other than those stated in 

Condition III.B.1 above shall not result in a resetting of the five-year permit term.

[A.A.C. R18-2-310.01] 

1. Excess emissions shall be reported as follows: 

a. The Permittee shall report to the Director any emissions in excess of the 

limits established by this permit. Such report shall be in two parts as 

specified below: 

i. Notification by telephone or facsimile within 24 hours of the 

time when the Permittee first learned of the occurrence of excess 

emissions including all available information from Condition 

XII.A.1.b 

ii. Detailed written notification by submission of an excess 

emissions report within 72 hours of the notification pursuant to 

Condition XII.A.1.a.i above. 

b. The report shall contain the following information: 

i. Identity of each stack or other emission point where the excess 

emissions occurred; 

ii. Magnitude of the excess emissions expressed in the units of the 

applicable emission limitation and the operating data and 

calculations used in determining the magnitude of the excess 

emissions; 
Permit No. 42782 Page 7 of 81 

iii. Date, time and duration, or expected duration, of the excess 

emissions; 

iv. Identity of the equipment from which the excess emissions 

emanated; 

v. Nature and cause of such emissions; 

vi. If the excess emissions were the result of a malfunction, steps 

taken to remedy the malfunction and the steps taken or planned 

to prevent the recurrence of such malfunctions; and 

vii. Steps taken to limit the excess emissions. If the excess 

emissions resulted from start-up or malfunction, the report shall 

contain a list of the steps taken to comply with the permit 

procedures. 

2. In the case of continuous or recurring excess emissions, the notification 

requirements of this section shall be satisfied if the source provides the required 

notification after excess emissions are first detected and includes in such 

notification an estimate of the time the excess emissions will continue. Excess 

emissions occurring after the estimated time period, or changes in the nature of 

the emissions as originally reported, shall require additional notification pursuant 

to Condition XII.A.1 above. 

[A.A.C. R18-2-310.01.C] 

B. Permit Deviations Reporting 

[A.A.C. R18-2-306.A.5.b] 

The Permittee shall promptly report deviations from permit requirements, including those 

attributable to upset conditions as defined in the permit, the probable cause of such 

deviations, and any corrective actions or preventive measures taken. Prompt reporting 

shall mean that the report was submitted to the Director by certified mail, facsimile, or 

hand delivery within two working days of the time when emission limitations were 

exceeded due to an emergency or within two working days of the time when the owner or 

operator first learned of the occurrence of a deviation from a permit requirement. 

C. Emergency Provision 

[A.A.C. R18-2-306.E] 

1. An “emergency” means any situation arising from sudden and reasonable 

unforeseeable events beyond the control of the source, including acts of God, that 

require immediate corrective action to restore normal operation, and that causes 

the source 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. 

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

noncompliance with such technology-based emission limitations if Condition 

XII.C.3 is met. 
Permit No. 42782 Page 8 of 81 

3. The affirmative defense of emergency shall be demonstrated through properly 

signed, contemporaneous operating logs, or other relevant evidence that: 

a. An emergency occurred and that the Permittee can identify the cause(s) 

of the emergency; 

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

c. During the period of the emergency, the Permittee took all reasonable 

steps to minimize levels of emissions that exceeded the emissions 

standards or other requirements in the permit; and 

d. The Permittee submitted notice of the emergency to the Director by 

certified mail, facsimile, or hand delivery within two working days of the 

time when emission limitations were exceeded due to the emergency. 

This notice shall contain a description of the emergency, any steps taken 

to mitigate emissions, and corrective action taken. 

4. In any enforcement proceeding, the Permittee seeking to establish the occurrence 

of an emergency has the burden of proof. 

5. This provision is in addition to any emergency or upset provision contained in 

any applicable requirement. 

D. Compliance Schedule 

[A.R.S. § 49-426.I.5] 

For any excess emission or permit deviation that cannot be corrected within 72 hours, the 

Permittee is required to submit a compliance schedule to the Director within 21 days of 

such occurrence. The compliance schedule shall include a schedule of remedial 

measures, including an enforceable sequence of actions with milestones, leading to 

compliance with the permit terms or conditions that have been violated. 

E. Affirmative Defenses for Excess Emissions Due to Malfunctions, Startup, and 

Shutdown 

[A.A.C. R18-2-310] 

1. Applicability 

This rule establishes affirmative defenses for certain emissions in excess of an 

emission standard or limitation and applies to all emission standards or 

limitations except for standards or limitations: 

a. Promulgated pursuant to Sections 111 or 112 of the Act; 

b. Promulgated pursuant to Titles IV or VI of the Clean Air Act; 

c. Contained in any Prevention of Significant Deterioration (PSD) or New 

Source Review (NSR) permit issued by the U.S. EPA;

Permit No. 42782 Page 9 of 81 

2. Affirmative Defense for Malfunctions 

Emissions in excess of an applicable emission limitation due to malfunction shall 

constitute a violation. When emissions in excess of an applicable emission 

limitation are due to a malfunction, the Permittee has an affirmative defense to a 

civil or administrative enforcement proceeding based on that violation, other than 

a judicial action seeking injunctive relief, if the Permittee has complied with the 

reporting requirements of A.A.C. R18-2-310.01 and has demonstrated all of the 

following: 

a. The excess emissions resulted from a sudden and unavoidable 

breakdown of process equipment or air pollution control equipment 

beyond the reasonable control of the Permittee; 

b. The air pollution control equipment, process equipment, or processes 

were at all times maintained and operated in a manner consistent with 

good practice for minimizing emissions; 

c. If repairs were required, the repairs were made in an expeditious fashion 

when the applicable emission limitations were being exceeded. Off-shift 

labor and overtime were utilized where practicable to ensure that the 

repairs were made as expeditiously as possible. If off-shift labor and 

overtime were not utilized, the Permittee satisfactorily demonstrated that 

the measures were impracticable; 

d. The amount and duration of the excess emissions (including any bypass 

operation) were minimized to the maximum extent practicable during 

periods of such emissions; 

e. All reasonable steps were taken to minimize the impact of the excess 

emissions on ambient air quality; 

f. The excess emissions were not part of a recurring pattern indicative of 

inadequate design, operation, or maintenance; 

g. During the period of excess emissions there were no exceedances of the 

relevant ambient air quality standards established in Title 18, Chapter 2, 

Article 2 of the Arizona Administrative Code that could be attributed to 

the emitting source; 

h. The excess emissions did not stem from any activity or event that could 

have been foreseen and avoided, or planned, and could not have been 

avoided by better operations and maintenance practices; 

i. All emissions monitoring systems were kept in operation if at all 

practicable; and 

j. The Permittee's actions in response to the excess emissions were 

documented by contemporaneous records. 

3. Affirmative Defense for Startup and Shutdown 
Permit No. 42782 Page 10 of 81 

a. Except as provided in Condition XII.E.3.b, and unless otherwise 

provided for in the applicable requirement, emissions in excess of an 

applicable emission limitation due to startup and shutdown shall 

constitute a violation. When emissions in excess of an applicable 

emission limitation are due to startup and shutdown, the Permittee has an 

affirmative defense to a civil or administrative enforcement proceeding 

based on that violation, other than a judicial action seeking injunctive 

relief, if the Permittee has complied with the reporting requirements of 

A.A.C. R18-2-310.01 and has demonstrated all of the following: 

i. The excess emissions could not have been prevented through 

careful and prudent planning and design; 

ii. If the excess emissions were the result of a bypass of control 

equipment, the bypass was unavoidable to prevent loss of life, 

personal injury, or severe damage to air pollution control 

equipment, production equipment, or other property; 

iii. The air pollution control equipment, process equipment, or 

processes were at all times maintained and operated in a manner 

consistent with good practice for minimizing emissions; 

iv. The amount and duration of the excess emissions (including any 

bypass operation) were minimized to the maximum extent 

practicable during periods of such emissions; 

v. All reasonable steps were taken to minimize the impact of the 

excess emissions on ambient air quality; 

vi. During the period of excess emissions there were no 

exceedances of the relevant ambient air quality standards 

established in Title 18, Chapter 2, Article 2 of the Arizona 

Administrative Code that could be attributed to the emitting 

source; 

vii. All emissions monitoring systems were kept in operation if at all 

practicable; and 

viii. Contemporaneous records documented the Permittee’s actions in 

response to the excess emissions. 

b. If excess emissions occur due to a malfunction during routine startup and 

shutdown, then those instances shall be treated as other malfunctions 

subject to Condition XII.E.2 above. 

4. Affirmative Defense for Malfunctions during Scheduled Maintenance. 

If excess emissions occur due to a malfunction during scheduled maintenance, 

then those instances will be treated as other malfunctions subject to Condition 

XII.E.2 above. 
Permit No. 42782 Page 11 of 81 

5. Demonstration of Reasonable and Practicable Measures 

For an affirmative defense under Condition XII.E.2 or XII.E.3, the Permittee 

shall demonstrate, through submission of the data and information required by 

Condition XII.E and A.A.C. R18-2-310.01, that all reasonable and practicable 

measures within the Permittee’s control were implemented to prevent the 

occurrence of the excess emissions. 

XIII. RECORD KEEPING REQUIREMENTS 

[A.A.C. R18-2-306.A.4] 

A. The Permittee shall keep records of all required monitoring information including, but 

not limited to, the following: 

1. The date, place as defined in the permit, and time of sampling or measurements; 

2. The date(s) analyses were performed;
