All sources with an aggregate heat input capacity greater than
five hundred million Btu per hour (500 MMBtu/hr) are subject to the
following:
460.1 Emission of sulfur
compounds, calculated as a calendar month average of sulfur dioxide, shall not
exceed one and one-half pounds per million Btu of heat input per hour (1.5 lbs
SO2/MMBtu, calendar month average of hourly
values).
460.2 Sources subject to
Section 460 shall submit an ambient monitoring proposal and monitoring schedule
for sulfur dioxide within one hundred and eighty (180) days of start-up. Each
proposal shall include:
460.21 At least one
recording meteorological station equipped to record wind speed and direction
and located and operated as in accordance with Appendix A of this
Regulation.
460.22 The sulfur
content and quantity of all materials, gaseous or liquid, fed to any boilers,
furnaces, heaters, flares or any other facility capable of generating heat,
resulting in emissions to the atmosphere. The sulfur content shall be expressed
in percent by weight of sulfur in each fuel type and shall contain an
explanation of how each was determined.
460.23 The method for monitoring the sulfur
content and quantity of fuel burned at each emission unit capable of emitting
sulfur to the atmosphere in quantities in excess of one hundred (100)
pounds/day of sulfur compounds calculated as sulfur dioxide. All emission units
capable of emitting less than one hundred (100) pounds/day of sulfur compounds,
calculated as sulfur dioxide may be monitored collectively as a single
emission.
460.24 The monitoring
proposal shall comply with provisions of Section 367 and Appendix A of this
Regulation.
460.3 The
total emissions of all sources located in that portion of Sections 2, 3, 4, 5,
9, Township 34 North and Sections 21, 27, 28, 29, 32, 33, 34, 35, in Township
35 North, Range 2 East, Willamette Meridian, all in Skagit County Washington,
and commonly known as March Point heavy industrial area, shall not exceed seven
thousand (7,000) pounds/hour of sulfur compounds, calculated as sulfur dioxide.
When the Control Officer reasonably believes that there exists
a substantial likelihood that this total is likely to be exceeded, he or she
shall establish additional temporary restrictions on any or all sources of
sulfur compounds in said area to maintain a total emission of less than seven
thousand (7,000) pounds/hour. The restrictions shall remain in force only so
long as the total emission will exceed 7,000 pounds/hour.
