I. AMBIENT MONITORING
CRITERIA POLLUTANTS
(A) METHODS AND EQUIPMENT
(1) Sulfur dioxide stations shall employ EPA's automated
			 equivalent method. All other monitors shall be operated and maintained as
			 described in the appropriate Sections of  40 CFR Part 50  and 40 CFR Part
			 58.
(2) Sample collection lines and instrument manifolds shall be
			 constructed of Teflon or glass. Residence time in the sampling line shall not
			 exceed 20 seconds.
(3) Analyzers shall be designated EPA reference or EPA designated
			 equivalent method. Sulfur dioxide monitors shall be operated in the 0 to 1 ppm
			 range.
(4) A Quality Assurance (QA) manual and a station log book shall
			 be kept for all stations. The station log book shall be used to record all
			 ongoing activities associated with station operation. Upon approval by the
			 NWCAA, electronic log books may be utilized.
(5) Strip charts shall be used for all monitors unless the data
			 acquisition system is capable of generating trend graphs from one-minute
			 measurement averages. Paperless strip charts are acceptable if configured to
			 store one-minute measurement averages. For sulfur dioxide stations using data
			 acquisition based storage, one-minute data shall be reviewed for possible
			 5-minute violations.
(6) All stations shall be operated on Pacific Standard Time
			 (PST).
(B) CALIBRATION
(1) Instruments shall be calibrated with National Institute of
			 Standards and Technology (NIST) reference materials or NIST-traceable secondary
			 standards, using standard reference methods and EPA-approved procedures.
(2) Each instrument shall be calibrated at least once every six
			 (6) months and whenever span or precision checks deviate by more than 10% of
			 the true value or the absolute value of the zero response is equal to or
			 greater than five times the resolution of the monitor (for sulfur dioxide
			 monitors, 0.005 ppm)
(3) Data precision shall be determined using single point
			 precision checks performed at least once every two (2) weeks. Precision tests
			 are performed by challenging the analyzer with a test gas of known
			 concentration (between 0.080 and 0.100 ppm for sulfur dioxide). Precision data
			 must be within ±10% of the true value.
(4) Data accuracy shall be assessed by performance audits and
			 weekly span checks. All continuous analyzers are to be zeroed and spanned at
			 least weekly at 70% to 90% of scale using a test gas of known concentration.
			 Make appropriate calibration adjustments if the analyzer response deviates by
			 more than 10% from the true value.
(5) All standard materials used for calibrations, precision and
			 span checks shall be recertified every 6 months, or new standard materials
			 shall be used.
(6) If precision and span checks are conducted at the same time,
			 the precision test shall be conducted prior to any zero and span
			 adjustments.
(7) Gaseous monitors shall not be zeroed or span checked manually
			 when pollutant levels are detected at more than 50% of any applicable 5-minute
			 or hourly short-term standard. Monitors shall not be zeroed or spanned more
			 than twice a day.
(8) Written calibration and precision/span check procedures shall
			 be included in the QA manual required under paragraph I(A)(4).

			 precision/accuracy of the instrument, a review of QA manual and other QA
			 materials, siting parameters and operating procedures, as well as an inspection
			 of the station log for maintenance and calibration documentation.
(3) When a monitor does not fall within defined limits or
			 tolerances, ambient data shall be invalidated back to the most recent point in
			 time at which measurements are known to be accurate or an event which can be
			 identified as the probable cause of the failure.

			 represent a major modification to the test method, or a less stringent
			 interpretation of applicable regulations.
(3) Where measured concentrations or emissions of pollutants are
			 below the method detection limit, the value of the detection limit shall be
			 used to calculate average emissions, and the results shall be reported as "less
			 than DL" if all runs were below the DL, and "less than" the average of the runs
			 if one or more runs were above the DL. The detection limit shall be in units of
			 the standard and actual DLs, whether standard or calculated, must be reported.

			 non-compliance with the applicable emission standard, the results may be
			 considered a violation of that standard.
(2) A stack test may be stopped due to severe weather, tester
			 equipment failure, unit failure, safety considerations, or other conditions
			 beyond the control of the facility. The NWCAA observer may void a test or
			 individual run on-site if procedures are determined to be employed
			 incorrectly.
