AQS & Monitoring
In This Section We Will Talk About Monitoring & AQS 2 In the field Before Monitoring QAPP – quality assurance project plan Annual monitoring plan Sampling schedule Coding the data stream for AQS Regulations Exceptional events Data certification process

Before Monitoring Monitoring & AQS 4 QAPP (Quality Assurance Project Plan) Ensures that the data collected meets the requirements Annual monitoring plan due to EPA Regional offices by July 1 st of each year Sampling Schedule Daily, 3-day & 6-day Monitoring Schedule for PM day Monitoring Schedule for TSP, Pb, PM-10, and VOC 12-day Monitoring Schedule for PM-2.5 Collocation Use the sampling schedule to ensure data completeness Duration Continuous monitors for CO, SO 2, NO x, No y Ozone data can be stored in any interval convenient to the S/L/T internal system; however hourly data (duration 1) is reported Filter-based data is usually reported as 24-hour (duration 7) integrated samples
Additional info for Reporting Data to AQS Monitoring & AQS 5 Monitors and Monitoring Agency Data Management Systems operate and report on “Local Standard Time” year-round (i.e., do not adjust clocks for daylight savings time) Daily Samplers typically operate from midnight to midnight for the day of interest Data are always reported with the Start Hour, e.g., a CO monitor that is reporting data would use “00:00” for the hour from midnight to 1 a.m. Data submittal requirements are described in CFR §58.16

(a) The State, or where appropriate, local agency, shall report to the Administrator, via AQS all ambient air quality data and associated quality assurance data for SO2; CO; O3; NO2; NO; NOY; NOX; Pb– TSP mass concentration; Pb–PM10 mass concentration; PM10 mass concentration; PM2.5mass concentration; for filter-based PM2.5FRM/ FEM the field blank mass, sampler-generated average daily temperature, and sampler-generated average daily pressure; chemically speciated PM2.5 mass concentration data; PM10–2.5 mass concentration; chemically speciated PM10–2.5 mass concentration data; meteorological data from NCore and PAMS sites; average daily temperature and average daily pressure for Pb sites if not already reported from sampler generated records; and metadata records and information specified by the AQS Data Coding Manual ( The State, or where appropriate, local agency, may report site specific meteorological measurements generated by onsite equipment (meteorological instruments, or sampler generated) or measurements from the nearest airport reporting ambient pressure and temperature. Such air quality data and information must be submitted directly to the AQS via electronic transmission on the specified quarterly schedule described in paragraph (b) of this section. (b) The specific quarterly reporting periods are January 1–March 31, April 1–June 30, July 1–September 30, and October 1–December 31. The data and information reported for each reporting period must contain all data and information gathered during the reporting period, and be received in the AQS within 90 days after the end of the quarterly reporting period. For example, the data for the reporting period January 1–March 31 are due on or before June 30 of that year. (c) Air quality data submitted for each reporting period must be edited, validated, and entered into the AQS (within the time limits specified in paragraph (b) of this section) pursuant to appropriate AQS procedures. The procedures for editing and validating data are described in the AQS Data Coding Manual and in each monitoring agency’s quality assurance project plan. (d) The State shall report VOC and if collected, carbonyl, NH3, and HNO3 data, from PAMS sites to AQS within 6 months following the end of each quarterly reporting period listed in paragraph (b) of this section. (e) The State shall also submit any portion or all of the SLAMS and SPM data to the appropriate Regional Administrator upon request.
Monitoring data for AQS - Site Monitoring & AQS 7 Monitoring instrumentation is at a particular location Need to have a site established in AQS State code + county code + site ID Metadata – data describing the physical location Site ACME Particulate Measuring Device
Monitoring data to AQS – What is required to set-up a Site? Monitoring & AQS 8 Unique Site ID Metadata needed: Latitude and longitude (in decimal degrees) Horizontal datum (what datum was used for lat/lon?) Horizontal method (how was lat/lon measured?) Horizontal accuracy (accuracy of lat/lon, in meters) Vertical measure (elevation, in meters) Vertical accuracy (accuracy of elevation, in meters) Vertical method (how elevation measured?) Street address, land use type and location setting Agency Role (agency that is supporting this site) Primary Monitor Period (for lead, NO2, PM2.5)
Monitoring instrument(s) for different parameters/pollutants In AQS, a “monitor”means the sampling for a single parameter at a Site… does not refer to the actual measuring device Monitoring Monitoring & AQS 9 PM10 - Total PM10 – Lead PM10 – Mercury PM10 - Nickel 4 AQS Monitors Site ACME Particulate Measuring Device
Monitoring data to AQS – What is required to set-up a Monitor? Monitoring & AQS 10 An established Site Parameter code POC (parameter occurrence code) – a sequence number when measuring multiple occurrences of the same pollutant Metadata: Vertical probe height, etc is optional Sample period begin date Monitor type (SLAMS, Tribal Monitor.. ) Agency roles Monitoring objective Required collection frequency Collocation info

NAAQS Monitoring Monitoring & AQS 17 SO 2 NAAQS SO 2 hourly standard (2010) requires 1-hour and 5-minute data designate PMP at site-level for a new SO 2 monitor SO 2 and related SO 2 hourly (42401, duration 1) New reporting requirement for SO 2 5-minute, effective August 23, 2010 If you are reporting:Use parameter:Use duration:Use POC:Notes: maximum 5-minute SO 2 average from each hour use AQS parameter code “42406” duration code of “1” Use of POC 1 is suggested but not required. all of the twelve 5-minute averages from each hour use AQS parameter code “42401” duration code of “H”Often duration “1” data is reported as POC 1, so the use of POC 2 (if available) is suggested but not required. Since “42401” is also used for hourly SO 2 (duration 1) data, a new POC must be established. The maximum 5-minute average for each hour does not have to be identified and separately reported.
NAAQS Monitoring Monitoring & AQS 18 NAAQS NO 2 hourly standard (2010) requires hourly NO 2 data NO 2 annual standard (1971) requires hourly NO 2 data NO 2 and related Hourly NO 2 (42602, duration 1) NO, NO x from NO 2 instruments NO, NO y from NO 2 instruments at NCORE sites Parameter codes NO = nitrogen oxide = NO 2 = nitrogen dioxide = NO x = oxides of nitrogen = NO y = reactive oxides of nitrogen = NO y – NO = difference channel output from NO y box = designate PMP for a new NO 2 monitor

Agency Roles Monitoring & AQS 29 Collecting Agency who maintains the instrument in the field? Reporting Agency Who reports the data to AQS? Required for all pollutants Analyzing Agency Who (which lab) analyzes the filters? PQAO (Primary Quality Assurance Organization) Agency Who is responsible for QA, audits, etc? Required for all pollutants Start date no earlier than 1/1/2007
Exceptional Event Rule Monitoring & AQS 30 The Federal Regulations (40 CFR Part 50.14) allow Ambient Air Quality Measurements that are Exceedances or Violations of the National Ambient Air Quality Standards (NAAQS) that are caused by an “Exceptional Event” to be excluded from Attainment demonstrations. (Exceptional Event Rule = EER)
EER – AQS Process Monitoring & AQS 31 Reporting Agency “flags” data with exceptional Event Flag, and submits justification to EPA Regional office either concurs with exclusion or “non-concurs” AQS computes summaries (daily, quarterly, and annual) that either include or exclude the flagged data, with a unique “Exceptional Data Type ID” AQS Reports will show either summary data flagged with EDT ID 0 0 – No data has been flagged OR 1, 2, and 5 1 – The summary excludes all flagged data 2 – The summary does not exclude any data 5 – The summary excludes regionally concurred flagged data
Data Completeness and Certification Monitoring & AQS 32 Submission of data sample data should be submitted to AQS by the end of the calendar quarter following the measurement date; ie, measurements from March 5 th should be submitted to AQS by June 30th Annual Data Certification For SLAMS and FRM, FEM and ARM SPM stations All PAMS except SPM Calendar year’s data must be certified by May 1 st of the following year; ie, CY2010 data must be certified by May 1, 2011 What’s needed?
