- All internal Quality Control data must be requested during the establishment of the laboratory work agreement or additional fees may apply.
- Requested spikes are assessed at the same price per sample as environmental samples.
- Samples submitted and then later requested not to be analyzed must be submitted in email within 3 days of sample submission or the sample will be assessed analysis costs.
- Re-analysis requests must be provided within 30 days of data delivery.
- Original sample bottles will be disposed 12 months after delivery of data unless otherwise agreed upon in the established laboratory work agreement.
- The OGRL must be notified by the end of Quarter 3 of the current fiscal year of any changes to the estimated sample totals in the established laboratory work agreement or additional fees may apply.

The concentrations for the family of isomers for chlortetracycline, oxytetracycline, and tetracycline are processed with the following differences and assumptions:
- Only one isomer per family is physically added in the standard mix and standard addition solutions (isochlotetracycline, oxytetracycline, tetracycline)
- Equal instrument response for each isomer in a family is assumed
- Concentration is calculated on the sum of all isomers in a family and proportioned by area of individual isomer
