MF - Monitor Sample Schedule
----------------------------

For intermittent monitors, this transaction defines the expected time periods between samples.

Rules
^^^^^

Monitor Sampling Schedule is required for PM10 and PM2.5 monitors.
Error Messages:

The Required Collection Frequency assignment for a production monitor cannot be changed, (i.e., updated or deleted), in a manner that would leave any portion of that monitor's sample periods since 1987-07-01 without a required collection frequency.

A Seasonal Required Collection Frequency assignment, (i.e., where RCF Code is "S"), requires at least twelve Monthly Collection Frequencies for a PM2.5 monitor and a seasonal or random Required Collection Frequency assignment, (.i.e., where RCF Code is "8", "9", or "S"), requires at least one Monthly Collection Frequency for a non-PM2.5 monitor.
