Threshold Set Citation

The citation on a ThresholdSet provides the legal reference that compliance staff and regulators can use to verify that the ThresholdValues in Piper match the official published standards. For example, a citation might read "22 CCR Section 64431 — Table 64431-A" for California drinking water standards, or "EPA OSWER Directive 9200.4-17P, Table 2." Including an accurate citation is essential when submitting exceedance notifications to regulatory agencies, as the notification must reference the specific standard that was exceeded and the authority that established it.
