inspection or Method 9 conducted by a District inspector may be counted as

meeting the requirement for the source to conduct same if the information and

records generated by the inspector meets the requirements of the permit and a copy

of the records are maintained by the source for a period of five years.

Record keeping provisions associated with all monitoring requirements shall

include the following information:

A. Identification of stack or emission point being monitored;

B. Operational conditions at the time of monitoring;

C. Records of any monitoring conducted, including records of emission or

federal, state and local air quality regulations.

IX. Paperwork Reduction Act

Any requirements established by this permit for the gathering and reporting if information are not subject

to review by the Office of Management and Budget (“OMB”) under the Paperwork Reduction Act

because this permit is not an “information collection request” within the meaning of 44

U.S.C.350(4)&(11), 3507, 3512 and 32518.

Futhermore, this permit and any information gathering and reporting requirements established by this

permit are exempt from OMB review under the Paperwork Reduction Act because it is directed to fewer

than ten persons. 44 U.S.C. 3502(4), (11), 5 C.F.R. 1320.5(a).

1. All point source emissions shall be controlled by baghouse type controls.

2. All raw materials transfer and crushing points upstream of kiln with potential to emit dust shall be

provided with water sprays with sufficient water volume to eliminate visible emissions.

3. Particulate control of haul roads shall be no less than 79.6% and shall be achieved by application of

water or KCAPCD-approved dust palliative(s). Visible fugitive dust emissions

from all haul roads shall not exceed 10% opacity.

C. Performance Tests

1. Within 60 days of achieving the maximum production rate of the proposed equipment but not later

than 180 days after initial startup of the equipment as defined in 40CFR 60.2(o), and at such other times

as specified by the EPA, NCCC shall conduct performance tests for NOx, NO2, CO and SO2 shall be

conducted and the results reported in accordance with the test methods set forth in 40 CFR 60, Part 60.8

and Appendix A. The following test methods shall be used:

a. Performance tests for the emissions of NOx and NO2 shall be conducted using EPA Methods 1-4 and

7E.

b. Performance tests for the emissions of SO2 shall be conducted using EPA Methods 1-4 and 8.

c. Performance test for the emissions of CO shall be conducted using EPA Methods 1-4 and 10

The EPA shall be notified in writing a lease thirty (3) days prior to such test to allow

time for the development of an approvable performance test plan and to arrange for an

observer to be present at the test.

Such prior approval shall minimize the possibility of EPA rejection of test results for

procedural deficiencies. In lieu of the above-mentioned test methods, equivalent methods

may be used with prior written approval from the EPA.

2. For performance test purposes, sampling ports, platforms and access shall be provided by NCCC

on the kiln exhaust stack in accordance with 40 CFR 60.8(e).

D. Emission Limits for Nitrogen Dioxide

On and after the date of this permit (Original: of startup), NCCC shall not discharge or cause the

discharge into the atmosphere NO2 in excess of 3.4 lbs/ton of clinker (30-day average) and 361.25

lb/hr (24-hour average) from the kiln stack (assumes 75% NO2 to NOx ratio). Enforcement of this

condition shall be based on NOx, CEM and NO2 to NOx ratio from most recent performance test.

EPA may set a new lower allowable emission rate for the above emission limits after reviewing the

performance test results or the initial NO2 monitoring data required under the Special Conditions C

and H.

If the NO2 emission limit is revised, the difference between the NO2 emission limit set forth above

and a revised lower NO2 emission limit shall be allowed as an emission offset for future

construction or modification.

E. Emission Limits for CO

On and after the date of startup, NCCC shall not discharge or cause to discharge into the

atmosphere CO in excess of the following amounts from kiln stack:

1. 3,000 lbs/hr (3-hour rolling average)

2. 2,000 lbs/hr (8-hour rolling average)

3. 1,200 lbs/hr (24-hour average)

EPA may set a new lower allowable emission rate for the above emission limits after reviewing the

performance test results or the initial CO monitoring data required under Special Conditions C and

H.

If the SO2 emission limit is revised the difference between the SO2 emission limit set forth above

and a revised lower SO2 emission limit shall not be allowed as an emission offset for future

construction or modification.

F. Emission Limits for Sulfur Dioxide

On or after the date of startup, NCCC shall not discharge or cause to discharge into the atmosphere

SO2 in exceeds of 53.83 lbs/hr (3-hour average) from the kiln stack.

EPA may set a new lower allowable emission rate for the above emission limits after reviewing the

performance test results or the initial SO2 monitoring data required under Special Conditions C and

H.

If the SO2 emission limit is revised, the difference between the SO2 emission limit set forth above

and a revised lower SO2 emission limit shall not be allowed as an emission offset for future

construction or modification.

G. Fuel Use and Operating Limits

1. NCCC shall only burn coal, petroleum coke, tire derived fuel (TDF), natural gas and/or fuel oil in the

kiln/preheater system. The maximum allowed TDF weight % is 50% of entire fuel mix, quarterly basis.

2. NCCC shall record and maintain records of the amounts of clinker produced, the plant hours of

operation, the amounts and type of fuel combusted, and TDF weight % each calendar quarter. All

information shall be recorded in a permanent form suitable for inspection. The file shall be retained for at

least two years following the date of such measurements, calculation and record.

H. Continuous Emission Monitoring

1. Prior to the date of startup and thereafter, NCCC shall install, maintain and operate the following

continuous emission monitoring systems in the main kiln stack:

a. Continuous monitoring systems to measure stack gas NOx, CO and SO2 concentrations. The systems

shall meet EPA monitoring performance specification (40 CFR 60.13 and 40 CFR 60, Appendix B,
