Ariz. Admin. Code § 18-2-729

Current through Register Vol. 30, No. 50, December 13, 2024

Section R18-2-729 - Standards of Performance for Cotton Gins

A. Fugitive dust, lint, bolls, cotton seed or other material emitted from a cotton gin or lying loose in a yard shall be collected and disposed of in an efficient manner or shall be treated in accordance with R18-2-604 through R18-2-607.

B. No person shall cause, allow or permit to be emitted into the atmosphere, from any type of incinerator, smoke, fumes, gases, particulate matter or other gas-borne material which exceeds 40% opacity.

C. No person shall cause, allow, or permit the discharge of particulate matter into the atmosphere in any one hour from any cotton gin in total quantities in excess of the amounts calculated by one of the following equations:

1. For process sources having a process weight rate of 60,000 pounds per hour (30 tons per hour) or less, the maximum allowable emissions shall be determined by the following equation:

E = 4.10P^0.67

where:

E = the maximum allowable particulate emissions rate in pounds-mass per hour.

P = the process weight rate in tons-mass per hour.

2. For process sources having a process weight rate greater than 60,000 pounds per hour (30 tons per hour), the maximum allowable emissions shall be determined by the following equation:

E = 55.0P^0.11 -40

where "E" and "P" are defined as indicated in subsection (C)(1).

D. The test methods and procedures required by this Section are as follows:

1. The reference methods in the Arizona Testing Manual and 40 CFR 60, Appendix A shall be used to determine compliance with this Section as follows:

a. Method A-2 for the measurement of particulate matter,

b. Method 1 for sample and velocity traverses,

c. Method 2 for velocity and volumetric flow rate,

d. Method 3 for gas analysis,

e. Method 9 for visible emissions.

2. For Method A-2, the sampling time for each run shall be at least 60 minutes and the sampling rate shall be at least 0.85 dry standard cubic meters per hour (0.53 dry standard cubic feet per minute), except that shorter sampling times, when necessitated by progress variables or other factors, may be approved by the Director.
