Regulatory Directive: Residue Chemistry Guidelines
1 June 1998
Cat. No.: N/A
The Pest Management Regulatory Agency (PMRA) has finalized the Residue Chemistry Guidelines (RCGs) as Regulatory Directive Dir98-02. Petitioners are requested to utilize these guidelines in preparing, conducting and reporting experimental studies in support of residue chemistry data requirements. These guidelines are the result of considerable consultation with stakeholders and have been harmonized with the United States Environmental Protection Agency's (EPA) RCGs. Since the PMRA and the EPA RCGs are identical, the preparation of experimental data using either guideline will fulfill the data requirements of both regulatory agencies. The adoption of a common zone map by the PMRA and the EPA maximizes the use of field trial residue data to meet the RCG data requirements. Data waiver requests will always be considered when supported by a scientifically defensible rationale as to why nonconformance to data requirements should be considered as acceptable to the PMRA.
These guidelines were developed to assist the petitioner in submitting a scientific data package that will proceed smoothly and expeditiously through the scientific evaluation/assessment process. The data generated in these studies will allow PMRA scientists to evaluate the validity of each study and to elucidate the nature and magnitude of residues in treated foods. Joint reviews and work sharing will be greatly facilitated with the harmonization of the PMRA's and the EPA's RCGs.
