Field trial data and processing data to support a SLN in state of ME for 75% WP formulation are outstanding.

16. Residue data from broccoli field trials will, by translation, fulfill data requirements for Brussels sprouts and cauliflower.

17. In order to accurately assess residue in/ on beans, data are required reflecting Uniroyal's current use pattern for beans, which allows for only a single field application at planting to beans ( excluding cowpeas) at a maximum of 1.5 lb ai/ A.

18. These studies have been submitted by Uniroyal and are currently under review.

19. Uniroyal's labeled uses on dry beans could potentially include use on soybeans. Therefore, field trial data are required reflecting the use PCNB on soybeans at the maximum rate. Alternatively, the registrant could prohibit direct field applications to soybeans, in which case separate field trial data for soybeans would not be required.

20. Data are required from Uniroyal depicting residues in/ on cottonseed following application of PCNB ( 2 lb/ gal EC and 10% G) at the maximum labeled rate ( 2 lb ai/ A). Uniroyal has submitted additional field trial data on cotton [ MRIDs 42534114, 42534115, and 43574901] reflecting use of G and EC formulations, which are currently under review. Residue data depicting PCNB residues in/ on cotton gin by products ( gin trash) is also required from six trials, three from each type of harvesting equipment ( stripper and mechanical picker).

21. These data were generated by Craven Laboratories and will not be used for assessing tolerances.

22. Although a total of 12 trials were conducted on peanuts, four different formulations were used. The Agency notes that Uniroyal formulations currently registered for use on peanuts include two granular ( G) formulations, a wettable powder ( WP), and a flowable concentrate ( FlC), and each of these formulations specify a maximum seasonal use rate of 2 lb ai/ A. An additional 10 field trials should be conducted in EPA Regions 2 ( 8 tests), Region 3 and 8 ( each 1 test) with the each of the three supported formulation for a total of 30 field trials. Samples of peanut hay must be taken and analyzed as well.

23. Seed treatment uses are no longer listed on any of Uniroyal's PCNB labels; therefore no additional residue data are required from crops that previously only had seed treatment uses.

24. Uniroyal submitted studies pertaining to its seed treatment uses ( MRIDs 41792601 41792605). These studies were not review by the Agency; however, Uniroyal has since deleted all seed treatment uses from its labels.

25. Residue data for ginseng should be generated in the representative countries and tolerance should be proposed.

26. A soybean processing study is required. Alternatively, the registrant could prohibit field applications to soybeans, in which case a soybean processing study would not be required.

27. Data requirements for plant metabolism, storage stability, and magnitude of the residues in/ on feed commodities must be fulfilled before requirements for animal feeding studies can be established.

28. CBRS No. 12326, DP Barcode D193790, F. Fort, 12/ 27/ 94.

29. The ChemSAC decided ( in June 2003) that based on all available data, PCNB treated crops should only be rotated to the labeled crops, therefore field accumulation studies on registered rotated crop are required. 70 Plant back interval in these studies should reflect the interval desired on product labels. The registrants are advised to consult the Agency in regard to which crops to be used in these studies. For information on conducting field accumulation studies on rotational crops, the registrant should refer to OPPTS Guideline No. 860.1900. ( continued; footnotes follow) 71 Table B2.

3. The nature of the residue in plants is not adequately understood. Additional data are required to upgrade Amvac's existing plant metabolism studies on peanuts, cabbage, and potatoes. In considering all three of Amvacs' plant metabolism studies, the Agency ( D184350 and D181195, J. Abbotts, 4/ 16/ 96) noted that the early metabolites in peanut, potato, and cabbage are similar, and the HPLC profiles of polar metabolites are also similar for these crops. Provided a new acceptable metabolism study is completed on potato or cabbage, including identification of the Unknown metabolites D and H, the Agency would be willing to conclude that the nature of the residue in plants was adequately understood.

10. As the available residue data on livestock feed items indicate that tolerances will be required for animal commodities, Amvac must propose a tolerance enforcement method for determining PCNB residues of concern in animal commodities.

11. The Agency has determined that PCNB, PCA, MPCPS, PCB, and HCB are completely recovered through PAM Vol. I, Methods 302, 303 and 304. No additional data are required ( D. Edwards, 8/ 1/ 86).

37. The ChemSAC decided ( in June 2003) that based on all available data, PCNB treated crops should only be rotated to the labeled crops, therefore field accumulation in registered rotated crop are required. Plant back interval in these studies should reflect the interval desired on product labels. The registrants are advised to consult the Agency in regard to which crops to be used in these studies. For information on conducting field accumulation studies on rotational crops, the registrant should refer to OPPTS Guideline No. 860.1900. 76 TOLERANCE REASSESSMENT SUMMARY Permanent tolerances for PCNB residues in/ on plant commodities are currently expressed as residues of PCNB per se [ 40 CFR § 180.291( a)] or as the combined residues of PCNB, and its metabolites, PCA and MPCPS [ 40 CFR § 180.291( b)]. There are also interim tolerances, which are also expressed as PCNB per se [ 40 CFR § 180.319]. There are presently no tolerances for PCNB in animal commodities.

The MARC met on April 16th , 2003 to determine the residues of concern for tolerance expression and for risk assessment. The MARC decided that as all the metabolites of PCNB are polychlorinated phenyl compounds and thus of toxicological concern, PCNB and all its metabolites ( including minor metabolites) are of concern in plants and animal commodities; they are currently more than 80 identified metabolites of concern. However, the residues of concern for tolerance setting purposes in primary and rotational crops, and livestock are PCNB, PCA, and PCTA.

Tolerances listed under § 180.319 should be reassigned to § 180.291( a) as time limited or permanent tolerances. Furthermore, all the current tolerance expressions which include PCNB per se should be changed to include PCNB, PCA, and PCTA per the MARC decision on 4/ 16/ 2003.

A summary of the PCNB tolerance reassessment and recommended modifications in commodity definitions are presented in Table C.

Tolerances Listed Under 40 CFR § 180.291( a):

Residue data for cottonseed must be submitted by both Uniroyal and Amvac before final decision is made. The current tolerance expressions which include PCNB per se should be changed to include PCNB, PCA, and PCTA per the MARC decision on 4/ 16/ 2003.

Tolerances Listed Under 40 CFR § 180.291( b):

Adequate residue data are available on collards, kale, and mustard greens grown in GA; these data indicate that the current 0.2 ppm regional tolerance is adequate.

Tolerances Listed Under 40 CFR § 180.319:

All tolerances for PCNB listed as " Interim tolerances" should be reassigned to § 180.291 and established as permanent or time limited tolerances. Furthermore, all the current tolerance expressions which include PCNB per se should be changed to include PCNB, PCA, and PCTA per the MARC decision on 4/ 16/ 2003. 77 Residue data from Uniroyal and Amvac support establishing a permanent tolerance at 0.1 ppm for the combined residues of PCNB, PCA, and PCTA in/ on head and stem Brassica vegetables Crop Subgroup. However, additional residue data for broccoli from Amvac are required.

The available residue data from Uniroyal would support establishing a permanent tolerance at 0.2 ppm for the combined residues of PCNB, PCA, and PCTA in/ on fruiting vegetables ( except Cucurbits); however, additional tests must be conducted by Amvac before a final decision can be made.

Based on the available residue data from Uniroyal, permanent tolerances should be established for garlic at 0.05 ppm. However, residue data must be submitted by Amvac.

Residue data are required from both Uniroyal and Amvac are required to establish a permanent tolerance in/ on potatoes.

The available residue data from Uniroyal and Amvac would support a temporary tolerance of 0.2 ppm for the combined residues of PCNB, PCA, and PCTA in/ on legumes; however, additional tests must be conducted before a permanent tolerance could be established.

The available residue data from Uniroyal and Amvac would support establishing a permanent tolerance at 0.5 ppm for the combined residues of PCNB, PCA, and PCTA in/ on peanut nutmeats, however, additional tests must be conducted before a final decision can be made.

Tolerances Needed Under 40 CFR § 180.291( a):

New tolerances are needed for PCNB residues in/ on cotton gin byproducts and potato, wet peel. Data are required from both Uniroyal and Amvac depicting PCNB residues in/ on cotton gin byproducts following application of PCNB at the maximum labeled rate.

Based on Amvac's potato field trials, the HAFT residues for potatoes are 0.95 ppm. Considering the HAFT residues and the 7x average concentration factor observed in Amvac's potato processing studies, the maximum expected combined residues in potato wet peel would be 6.65 ppm. Therefore, a tolerance of 7.0 ppm should be established for the combined residues of PCNB in potato, wet peel. However, supporting storage stability data for processed potato fractions are required to upgrade this processing study. Samples from the potato processing study were stored frozen for up to 218 days prior to analysis.

New tolerances are also needed for PCNB residues in/ on RACs of barley, corn, oats, peas, rice, safflower, sugar beets, soybeans, and wheat grown from seed treated with PCNB at the maximum labeled rate.

Adequate residue data are available from Amvac supporting the seed treatment of soybeans. These data indicate that separate tolerances should be established at 0.02 ppm in/ on soybean forage, hay, and seeds. However, seed treatment data for cereal grains, peas, safflower, and sugar beets remain outstanding. 78 Based upon the available feeding studies and the calculated theoretical dietary burdens for livestock, tolerances are required for animal commodities. Based on the regulated residues in animals, i. e., PCNB, PCA, and MPCPS, a tolerance of 0.05 ppm should be established for milk and tolerances of 1.0 ppm should be established for residues in meat, fat, and mbyp of cattle, goats, horse, and sheep. Tolerances should also be established at the enforcement method LOQ for residues in hog fat, meat, and mbyp; however, an enforcement method for animal commodities is not currently available.

A tolerance of 0.5 ppm should be established for residues in poultry fat, and tolerances of 0.05 ppm should be established for residues in eggs and poultry mbyp. A tolerance of poultry meat is not required as detectable residues are unlikely to occur in meat. 79 ( continued; footnotes follow) Table C. Tolerance Reassessment Summary for PCNB.

Furthermore, all the current tolerance expressions which include PCNB per se should be changed to include PCNB, PCA, and PCTA per the MARC decision on 4/ 16/ 2003. 81 DIETARY EXPOSURE ASSESSMENT SUMMARY A) PCNB A revised probabilistic chronic dietary risk assessment was completed on March 31st, 2004 ( Mohsen Sahafeyan, D298352, 3/ 31/ 2004). This chronic dietary risk assessment is considered to be a highly refined assessment using all available monitoring data, % CT ( percent crop treated) information, and processing factors. However, because monitoring data did not analyze for all PCNB metabolites of concern ( 86 identified metabolites), the ratio of total radioactive residues ( TRR) to PCNB from available metabolism studies is used in combination with monitoring residue data on PCNB. Otherwise, TRR values by themselves were used to estimate the total residues of concern.

This risk assessment was performed with both Dietary Exposure Evaluation Model Food Consumption Intake Database ( DEEM FCIDJ) and Lifeline models. The 1994 1998 USDA's Continuing Surveys of Food Intake by Individuals ( CSFII) was used by both models for a consumption data base. Since the results from both models were close, only those from DEEMFCID model are summarized below.

Two chronic dietary risk assessment were conducted. The first one includes both registered and unregistered commodities. This is because monitoring residue data show considerable number of detects in unregistered commodities. That is believed to be due to rotational crop effect based on the available studies and evidences. It is believed that the wide presence of PCNB and/ or its residues on unregistered crops are due to its uptake from soil by rotated crops ( rather than illegal use), which in turn is due to a very long half life ( 1555 days) of PCNB and/ or its metabolites in soil. The Chemistry Science Advisory Committee ( ChemSAC) has concluded that rotational crop restrictions to registered crops beyond 1 year is not enforceable and thus is impractical. Therefore, there is no practical expectation that dietary risks from PCNB on these unregistered crops could be mitigated by further restrictions on crop rotations.

The second risk assessment includes only registered commodities and was conducted in the interest of completeness but may not reflect the existing total dietary risk in the food chain from use of PCNB and its metabolites.

An important reminder is that the chronic dietary risk estimates are subject to change should the 2004 monitoring data on milk samples ( unavailable yet) from United States Agriculture Department, Pesticide Data Program ( USDA PDP) indicate the presence of higher levels of PCNB and its metabolites than what was assumed in that assessment.

The results of these chronic dietary risk assessments show that the risk for all population subgroups are below the level of concern; i. e., 100% cPAD. For the chronic dietary risk due to all crops, i. e., both registered and unregistered crops, the general U. S. population had 12% cPAD and population subgroup children 1 2 years old had the highest estimated risk of 34% cPAD. For the chronic dietary risk due to registered crops, the general U. S. population had 10% cPAD and population subgroup children 1 2 years old had the highest estimated risk of 27% cPAD. 82 When water was added to the analysis, % cPAD exceeded 100% for all populations except youth 13 19 with % cPAD of 78% and adults 20 49 with % cPAD of 97%; all other population subgroups exceeded the 100% cPAD mark and thus are of concern. The estimated risk including water for general U. S. population is 105% cPAD and the highest estimated risk is for population subgroup all infants with the 313% cPAD.

B) PCP Residues of free PCP, a known carcinogen, and conjugated PCP were found in some crops, and were detected in an anaerobic soil metabolism study and a terrestrial field dissipation study. With one exception, the conjugated PCP residues were thiol compounds that are not expected to form the phenol during metabolism/ degradation. Of potential concern, because it may cleave to form PCP, is PCP glycoside ( PCP Gly) that was found in potato callus and peels in an early, inadequate, metabolism study ( MRID# 41562903). In a more recent, adequate, potato metabolism study, callus and peels were not sampled separately, but no PCP Gly was found in any potato samples. Free PCP was detected in a rotational crop study on turnip one year following soil treatment at 10 or 2 lbs ai/ A. The concentrations were < 0.001 ppm in tops and < 0.004 ppm in roots. In the case of the rotational crop study, PCNB is not registered for use on turnips, but turnips were rotated into a field where crops were treated with PCNB.

A first tier worst case analysis was conducted assuming 0.004 ppm residues of PCP in all tuber crops and using the recently revised Q 1* ( 3/ 4 scaling factor) of 0.07 x 10 1 mg/ kg day. Under these circumstances, the potential risk may be 5 x 10 8 ( general population), which is not of concern.

CODEX HARMONIZATION As there are no established or proposed Codex maximum residue limits ( MRLs) for PCNB, harmonization of U. S. tolerances with Codex is not required. 83 AGENCY MEMORANDA CITED IN THIS DOCUMENT DP Barcode: None Subject: Addendum to the Residue Chemistry Chapter of the PCNB Registration Standard B Analytical Methods and Regulatory Incidents.
