SECTION 5.06 - GENERAL STANDARDS FOR MAXIMUM PERMISSIBLE EMISSIONS

All sources and emissions units are required to meet the emission standards of this chapter. Where an emission standard listed in another chapter is applicable to a specific emissions unit, such standard wi ll take precedent over a general emission standard listed in this chapter. When two or more emissi ons units are connected to a common stack and the operator elects not to provide the means or facilities to sample emissions from the individual em issions units, and the re lative contributions of the individual emissions units to the common dis charge are not rea dily distinguishable, then the emissions of the common stack must meet the most restric tive standard of any of the connected emissions units. Further, all emissions units are required to use reasonably available control technology (RACT) which may be determined for some sources or source categories to be more stringent than the applicable emission limitations of any chapter of Title 173 WAC. Where curren t controls are determined to be less than RACT, ecology or the authority sha ll, on a case-by-case basis, define RACT for each source or source category and issue a regula tory order to the source or sources for installation of RACT.

A. Visible Emissions. No person shall cause or pe rmit visible plume from any s ource that exceeds twenty percent (20%) opacity for three min utes in any one hour period except:

1. When the emissions occur due to soot blowing/grate cleaning and the operator can demonstrate that the em issions will not exceed twenty percent (20%) opacity for more than fift een minutes (15) in any eight (8)
consecutive hours. The inte nt of this provision is to permit the soot blowing and grate cleaning necessary to the ope ration of boiler facilities. This practice, except for testing and trouble shooting, is to be scheduled for the same approximate times each day an d the Authority be advised of the
schedule.

2. When the owner or operator of the source supplies va lid data to show that the opacity exceeds twenty percent (20% ) as the result of the presence of condensed water droplets. The concentrat ion of particulate matter as shown by a source test approved by the Authorit y must be less than one-tenth (0.1) grains per dry standard cubic foot. For combustion emissions the exhaust gas volume shall be corrected to seven percent (7%) oxygen.

3. As provided for in WA C 173-433-110 "Opacity St andards For Solid Fuel

B. Preventing particulate ma tter from becoming airborne. No person shall cause or perm it the emission of particulat e matter from any source which is transported or becomes deposited beyond the property under direct control of the owner or operator of the source in su fficient quantity to i nterfere unreasonably with the use and enjoyment of the property upon wh ich the material was transported or deposited.

C. Material handling. No person shall cause or permit ma terial handling without taking reasonable precautions to prevent the release of contaminants to the ambient air.

D. Odor. Any person who shall cause or allow the generation of any odor from any source which may unreasonably i nterfere with an adjoining property owner's use and enjoyment of his property must use recogni zed good practice and procedure to reduce
these odors to a reasonable minimum.

E. Air contaminants or water vapor detrimental to persons or property. No person shall cause or permit the emiss ion of any air contam inant or water vapor from any source, including a ny air contaminant whose emission is not otherwise prohibited by this Regulation, if the air contaminant or wate r vapor causes detriment to the health, safety, or welfare of any pers on, or causes damage to property or business.

F. Sulfur dioxide.
1. No person shall cause or permit the emission of a gas containing sulfur dioxide in excess of 1,000 parts per million (ppm).

2. All concentrations of sulfur dioxide referred to above are by volume, dry standard conditions, and for combustio n emissions the exhaust gas volume shall be corrected to seven percent (7%) oxygen and based on the average of any period of si xty consecutive minutes.

G . Concealment and masking. No person shall cause or perm it the installation or use of an y device, or the use of any means which, without resulting in a reduction in the total am ount of air contaminant emitted, conceals an emission of an air c ontaminant which would otherwise violate any provisions of this chapter.

H. Fugitive dust sources.
1. The owner or operator of a source of fugitive dust shal l take reasonable precautions to prevent fugitive dust fro m becoming airborne and shall maintain and operate the s ource to minimize emissions.

2. The owner(s) or operator(s) of a ny existing source(s) of fugitive dust that has been identified as a significan t contributor to a Category I PM-10 area Page 2 of 3 SIP - YRCAA - Section 5.06

...shall be required to use reasona bly available control technology to control emissions. Significance will be determined by the definition found in 40 CFR Part 51, Appendix S, as amended July 1, 1990.

I. No person shall hereafter sell or install within the jurisdiction of the Yakima County Clean Air Authority any cont inuous, stationary air contamina nt source in which the air
contaminant emitted therefrom cannot be restricted to the standards as set forth in Sections 5.06(A) and 5.08.

J. The density or opacity of an air contaminant shall be measured at the point of its emission, except when the point of emission cannot be re adily observed it may be measured at an observable point on a plume nearest the point of emission.
