Sampling Schedule Offset

Description

The number of days this monitor’s schedule samples are “offset” from the standard sampling schedule. The EPA standard schedule baseline date is 1/4/1956 and all non-daily sampling schedules are calculated from that date. If an offset is provided, this monitor’s schedule will be calculated from 1/4/1956 + offset value. (The sampling schedule for each year is posted on AMTIC.)

Business Rules

Must be a number greater than zero and less than the interval associated with the specified RCF. That is, if the RCF is every third day, the offset must be 1 or 2.
