CY - PGC

CY - PGC = Protocol Gas Cylinder

This transaction is used to define the Producer ID (PGVP-ID) / Cylinder ID owned by an agency and the associated gas in the cylinder. This transaction is used to update end use date of a gas when the cylinder is refilled. When a cylinder has the same parameter defined twice the dates may not overlap.

Rules

A parameter defined for a cylinder may not be deleted if it is in use for an assessment.

Expiration Date/Last Use Date may not be null. The field should be updated if the gas runs out and the cylinder is refilled before the prior fill's expiration date.

A record is unique to a PGVP-ID / Cylinder ID / Agency Code combination.

If a cylinder is refilled with the same gas as before then there may not be any overlap of the certification date and expiration/last use date.

Parameter code(s) of the certified standard in a cylinder may only be CO, SO2, NO or NOx.
