Common use of Continuous Data Clause in Contracts

Continuous Data. For the swine and dairy sites, the continuous sampling program under the NAEMS consisted of long- and short-term monitoring. Under long-term monitoring, continuous measurements were taken over a one-year period at a single site for each animal type (site IN4A for swine and site IN5A for dairy). The short-term monitoring consisted of continuous measurements taken at multiple sites on a rotating sampling schedule over a two-year period. Meteorological and lagoon liquid data were recorded as 5-minute average values, and emissions data were reported as 30-minute averages. These data were aggregated by the NAEMS researchers to obtain daily values. Consistent with the EPA’s Guidance for Quality Assurance Project Plans (EPA QA/G- 5), data completeness is defined as the measure of the amount of valid data obtained from a measurement system, compared to the amount of data that was expected to be obtained under normal conditions. Data completeness is expressed as the percent of valid data obtained from the measurement system. For data to be considered valid, they must meet all the acceptance criteria. As specified in the NAEMS QAPP, a valid day for a pollutant or process parameter was one in which more than 75 percent of the 30-minute measurement values recorded were valid (i.e., 36 half hours in the day passed all QA checks). The long-term monitoring sites had a second completeness goal to obtain valid emissions measurements for 75 percent of the total number of monitoring days on site (273 days would meet daily completeness criteria). For the short-term monitoring sites, the second completeness goal was to obtain emissions measurements for 10 days per quarter. The duration of the sampling events at any one site was dictated by weather conditions with a maximum duration of 21 days per quarter. The maximum duration was intended to ensure that the data quality indicator of 75 percent completeness of 10 days per quarter would not be prevented by adverse weather. Table 4-1 summarizes the monitoring schedule, the number of valid emissions days and data completeness by site. Table 4-1 also shows the quarter and season corresponding to each monitoring day. To simplify the seasonal assignments, if the monitoring period overlapped with another season by less than 15 days, the EPA assigned the monitoring period to the season that had the majority of days. The EPA assigned monitoring periods that overlapped the next season by more than 15 days as mixed- season periods (e.g., Fall/Winter). In the development of EEMs, the EPA considered all valid data days regardless of whether or not the NAEMS completeness goal was achieved. At all of the short-term monitoring sites, the measurement instrumentation was on site for at least once each quarter/season over the 2-year monitoring period. For NH3 emissions calculated using the RPM model, the 75-percent completeness criteria was achieved only at site OK4A. The final reports submitted to EPA do not discuss data completeness and do not provide detailed reasons for why the completeness goals were not achieved.
