Monitoring & AQS


Before monitoring
Before Monitoring

  • QAPP (Quality Assurance Project Plan)

    • Ensures that the data collected meets the requirements

  • Annual monitoring plan

    • due to EPA Regional offices by July 1st of each year

  • Sampling Schedule

    • Daily, 3-day & 6-day Monitoring Schedule for PM-2.5

    • 6-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

    • http://www.epa.gov/ttnamti1/calendar.html

  • Duration

    • Continuous monitors for CO, SO2,NOx,Noy

    • 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

Monitoring & AQS


Additional info for reporting data to aqs
Additional info for Reporting Data to AQS

  • 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

§ 58.16 Data submittal and archiving

requirements.

(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 (http://www.epa.gov/ttn/airs/airsaqs/manuals/manuals.htm). 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.

Exceptional event rule
Exceptional Event Rule

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)

Monitoring & AQS


Eer aqs process
EER – AQS Process

  • 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

Monitoring & AQS


Data completeness and certification
Data Completeness and Certification

  • 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 5th 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 1st of the following year; ie, CY2010 data must be certified by May 1, 2011

  • What’s needed?

    • Data certification statement signed by the senior air pollution monitoring person from the monitoring agency in the form of a letter to the EPA Regional Administrator

    • AQS summary report

      • AMP450 (QuickLook) for CO, NO2, SO2, ozone, PM10, lead (12128) and PM2.5

      • AMP450NC (QuickLookNonCriteria) for other pollutants, lead (14129)

    • AQS quality assurance report – AMP255 (Data Quality) – for each monitor in the PQAO

      • See 40CFR 58 Appendix A; should be done for each PQAO
