PERMIT MODIFICATION

Collins Pine Company in Chester, California

(NSR 4-4-4, SAC 84-02)

The modified PSD permit issued to Collins Pine Company allows the existing wet electrostatic 

precipitator control device to be replaced by a dry electrostatic precipitator.

The EPA hereby amends Special Conditions X.B, X.D, X.F, X.G and X.I as set forth in the PSD Permit issued 

by EPA Region 9 to Collins Pine Company on July 18, 1997 to read as follows:

B. Air Pollution Control Equipment

Collins Pine Company shall install, continuously operate, and maintain the following air pollution 

controls to minimize boiler #4 emissions: 

1. Collins Pine shall operate and maintain a multiclone dust collector. All exhaust gases from 

boiler #4 shall be directed through the multiclone.

2. Collins Pine shall operate and maintain a dry electrostatic precipitator (ESP). 

3. All exhaust gases from boiler #4 shall be vented through the multiclone and then through 

the dry ESP prior to venting to the atmosphere.

D. Fuel Usage

In boiler #4, Collins Pine Company shall burn only wood waste, clean lumber, yard waste, or 

mixture of only wood waste, clean lumber, and/or yard waste. Clean lumber means wood or 

wood products that have been cut or shaped and include wet, air-dried, and kiln dried wood 

products. Clean lumber does not include wood products that have been painted, pigmentstained, or pressure-treated by compounds, or manufactured wood products that contain 

adhesives or resins (e.g., plywood, particle board, flake board, and oriented strand board). 

Wood waste is limited to untreated wood and untreated wood products. Wood waste includes 

tree stumps (whole or chipped), trees, tree limbs (whole or chipped), bark, sawdust, chips, 

scraps, slabs, millings, and shavings. Wood waste does not include: (1) Grass, grass clippings, 

bushes, shrubs, and clippings from bushes and shrubs from residential, commercial/ retail, 

institutional, or industrial sources as part of maintaining yards or other private or public lands. 

(2) Construction, renovation, or demolition wastes. (3) Clean lumber. (4) Treated wood and 

treated wood products, including wood products that have been painted, pigment-stained, or 

pressure-treated by compounds, or manufactured wood products that contain adhesives or 

resins (e.g., plywood, particle board, flake board, and oriented strand board). Yard waste means 

grass, grass clippings, bushes, shrubs, and clippings from bushes and shrubs. Yard waste comes 

from residential, commercial/ retail, institutional, or industrial sources as part of maintaining 

yards or other private or public lands. Yard waste does not include: (1) Construction, renovation, 

and demolition wastes. (2) Clean lumber.

In boiler #4, Collins Pine can use Ultra Low Sulfur diesel fuel on startup events. (Limit of 10 

gallons per event).
F. Performance Tests

1. Within 60 days after achieving the maximum production rate, but no later than 90 days 

after commencing operation, and at such times as may be specified by the EPA, Collins 

Pine shall conduct or cause to be conducted performance tests (as defined in 40 CFR 

60.8) for PM10, PM2.5, NOx, CO, and opacity on the exhaust gases from the ESP stack, 

and shall furnish the EPA (Attn: ENF-2) a written report of the results of such tests. The 

tests for PM10, PM2.5, NOx, CO, and opacity at the ESP stack shall be conducted on an 

annual basis and at the maximum operating capacity of the facilities being tested. Upon 

written request and with supporting justification from Collins Pine, EPA may waive a 

specific annual test and/or allow for testing to be done at less than the maximum 

allowable operation capacity. Such request must be submitted (Attn: ENF-2) no later 

than 60 days prior to the annual test date.

2. Performance tests for the emissions of NOX, PM10, CO and PM2.5 shall be conducted 

and 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 shall be conducted using EPA 

Methods 1-4 and 7e,

b. Performance tests for the emissions of PM10 (Front half) shall be conducted 

using EPA Methods 1-4 and 201a,

c. Performance tests for the emissions of CO shall be conducted using EPA 

Methods 1-4 and 10,

d. Performance test for opacity shall be conducted using EPA method 9.

e. Performance tests for the emissions of PM2.5, inorganic and organic 

condensable particulate matter, shall be conducted using EPA Methods 1-4 and 

202 (Dry impinger method).

G. Emission Limits

On and after the effective date of this permit, Collins Pine shall not discharge, or cause the 

discharge into the atmosphere from boiler #4 pollutants in excess of the more stringent of the 

following specified limits:

Pollutant Mode Emission Limits

NOX Normal 55 lb/hr or 145 ppm @ 12 % C02 (3-hr avg)

Transient 85 lb/hr or 165 ppm@ 12% C02 (3-hr avg)

Pollutant Mode Emission Limits

CO Normal 220 lb/hr (3-hr avg)

Transient 950 lb/hr (3-hr avg)

Transient 575 lb/hr (8-hr avg)
Pollutant Maximum Emission Limit

PM10 13 lb/hr or 0.0265 gr/dscf@ 12 % C02 (3-hr avg)

Opacity Limits

On and after the effective date of this permit, Collins Pine shall not discharge or cause 

the discharge into the atmosphere from boiler #4 gases which exhibit an opacity of 20% 

or greater for any period of periods aggregating more than three minutes in any one 

hour.

Revision of Emission Limits

If the emission limit for any of the above pollutants is revised, the difference between the 

pollutant emission limit set forth above and the lower pollutant emission limit shall not be 

allowed as an emission offset for future construction or modification.

I. Continuous Emission Monitoring and Recordkeeping

3. Collins Pine shall maintain a file of all measurements and visibility observations, 

including continuous monitoring systems evaluations; all continuous monitoring 

systems or monitoring device calibration checks; adjustments and maintenance 

performed on these systems or devices; total annual hours of operation; hours 

operated in the transient or bypass mode; performance and all other 

information required by 40 CPR 60 recorded in a permanent form suitable for 

inspection. The file shall be retained for at least five years following the date of 

such measurement, maintenance, reports and records.

Diesel Fuel Recordkeeping: record amount of diesel fuel used during startup events 

to maintain flame stabilization. (Limit of 10 gallons per event).

All other permit conditions are unchanged and remain in effect.
