Summary of Petition

     The petitioner summary of the pesticide petition is printed below 
as required by section 408(d)(3) of the FFDCA. The summary of the 
petition was prepared by the Interregional Research Project Number 4, 
and represents the view of the Interreional Research Project. EPA is 
publishing the petition summary verbatim without editing it in any way. 
The petition summary announces the availability of a description of the 
analytical methods available to EPA for the detection and measurement 
of the pesticide chemical residues or an explanation of why no such 
method is needed.

PP 1E6322

     EPA has received a pesticide petition (1E6322) from the 
Interregional Research Project Number 4, 681 U.S. Highway 1 South, 
North Brunswick, New Jersey 08902-3390] proposing, pursuant to section 
408(d) of the FFDCA, 21 U.S.C. 346a(d), to amend 40 CFR 180.479 by 
establishing a tolerance for residues of the herbicide [halosulfuron, 
methyl 5-[(4,6-dimethoxy-2-pyrimidinyl) amino]carbonylaminosulfonyl-3-
chloro-1-methyl-1H-pyrazole-4-carboxylate] in or on the raw 
agricultural commodities (RAC) dry bean and succulent snap bean at 0.05 
parts per million (ppm). EPA has determined that the petition contains 
data or information regarding the elements set forth in section 
408(d)(2) of the FFDCA; however, EPA has not fully evaluated the 
sufficiency of the submitted data at this time or whether the data 
support granting of the petition. Additional data may be needed before 
EPA rules on the petition. This notice includes a summary of the 
petition prepared by Gowan Company, Yuma, Arizona 85366.

A. Residue Chemistry

    1. Plant metabolism. The metabolism of halosulfuron-methyl as well 
as the nature of the residues in plants is adequately understood for 
purposes of this tolerance.
    2. Analytical method. A practical analytical method, gas 
chromatography with a nitrogen specific detector (TSD) which detects 
and measures residues of halosulfuron-methyl, is available for 
enforcement purposes with a limit of detection that allows monitoring 
of food with residues at or above the levels set in these tolerances. 
This enforcement method has been submitted to the Food and Drug 
Administration for publication in the Pesticide Analytical Manual (PAM 
II). It has undergone independent laboratory validation and validation 
at the Beltsville laboratory.
    3. Magnitude of residues. In snap and dry bean residue studies, 
there were no quantifiable residues found in the RAC using an 
analytical method with limit of quantitation (LOQ) of 0.05 ppm.

B. Toxicological Profile

    The nature of the toxic effects caused by halosulfuron-methyl is 
discussed in unit II.B of the Federal Register on April 31, 2001 (66 FR 
45993) (FRL-6796-1).

C. Aggregate Exposure

    1. Dietary exposure. Tolerances have been established (40 CFR 
180.479) for residues of halosulfuron-methyl in or on a variety of 
plant and animal RACs.
    i. Food-- a. Acute exposure. For purposes of assessing the 
potential dietary exposure from food under existing and proposed 
tolerances, the aggregate exposure is based on the Theoretical Maximum 
Residue Contribution (TMRC) which is an estimate of the level of 
residues consumed daily if each food item contained pesticide residues 
equal to the tolerance.
    The calculated TMRC value using the 99.9th percentile 
consumption data was 0.006 milligrams/kilograms bodyweight day (mg/kg 
bwt day) or 1.2% acute Reference Dose (aRfD) for the general U.S. 
population. TMRC is obtained by multiplying the tolerance levels for 
each commodity by the daily consumption of the food forms of that 
commodity eaten by the U.S. population and various population 
subgroups.
    In conducting this exposure assessment, conservative assumptions 
were made resulting in a large overestimate of human exposure. Thus, 
the dietary exposures to halosulfuron-methyl are less 3.0% aRfD for all 
sub-populations. Food consumption data from DEEM software were used in 
the calculation.
    b. Chronic exposure. The chronic Reference Dose (cRfD) is 0.1 mg/
kg/day. For all established and proposed tolerances of halosulfuron-
methyl, the calculated TMRC value for the U.S. population is 0.00049 
mg/kg/day or 0.5% RfD.
    ii. Drinking water. The estimated environmental concentrations 
(EECs) in ground water (acute and chronic) is 0.008 [mu]g/L. The 
estimated EECs (acute and chronic) for surface water are 4.3 [mu]g/L 
and 1.1 [mu]g/L, respectively. These estimates are based on a maximum 
application rate of 0.063 lbs. active per acre, which may be applied 
twice per season. There is no Maximum Contaminant Level (MCL) 
established for residues of halosulfuron-methyl.
    2. Non-dietary exposure. The non-dietary exposure assessment for 
halosulfuron-methyl is discussed in unit II.C of the Federal Register 
on April 31, 2001 (66 FR 45993) (FRL-6796-1).

D. Cumulative Effects

    The potential for cumulative effects for halosulfuron-methyl is 
discussed in unit II.D of the Federal Register on April 31, 2001 (66 FR 
45993) (FRL-6796-1).

E. Safety Determination

    1. U.S. population. Aggregate chronic exposure to halosulfuron-
methyl from ``food only'' utilizes less than 1% of the chronic 
populated adjusted dose (cPAD) for the most sensitive subgroup, 
children (1-6 years). The lowest drinking water level of concern 
(DWLOC) calculated was 1,000 [mu]g/L for infants and children which is 
significantly higher than the EEC for chronic ground water (0.008 
[mu]g/L) and surface water (1.1 [mu]g/L). As a result, the aggregate 
risk from chronic exposure to halosulfuron-methyl residues from all 
anticipated dietary exposures does not pose appreciable risks to human 
health.
     Short-term risk--short-term aggregate exposure takes into account 
chronic dietary food and water plus short-term residential exposure. 
For halosulfuron-methyl, the EPA has determined that it is appropriate 
to aggregate exposure via

[[Page 38279]]

oral exposure route (food and water) with those via oral and dermal 
exposure routes from residential uses. The MOEs for ``food only'' and 
residential exposure routes are 113, 600, and 330 for females 13+ 
years. Short-term DWLOC for females 13+ is 10,000 [mu]g/L which is 
substantially higher than the EECs for acute surface water (4.3 [mu]g/
L). The food only and residential (oral and dermal) MOEs are well above 
the acceptable short-term aggregate MOE of 100. Therefore, exposure to 
halosulfuron-methyl residues resulting from current and proposed uses 
does not pose a short-term aggregate risk.
     Intermediate-term risk--intermediate-term aggregate exposure takes 
into account chronic dietary food and water plus intermediate-term 
residential exposure. The MOEs for ``food only'' and residential 
exposure routes are 22,800 and 120 for adult males, and 23,000 and 100 
for females 13+ years. The intermediate-term DWLOCs are 590 [mu]g/L and 
57 [mu]g/L, respectively, for adult males and females 13+. 
Intermediate-term DWLOCs are substantially higher than the EEC for 
chronic surface water (1.1 [mu]g/L). The food only and residential 
(dermal) MOEs are above the acceptable short-term aggregate MOE of 100. 
Therefore, exposure to halosulfuron-methyl residues resulting from 
current and proposed uses does not pose a intermediate-term aggregate 
risk.
     Halosulfuron-methyl has been classified as a Group E chemical 
based upon the lack of evidence of carcinogenicity in mice and rats, 
and has been classified as not likely to be a human carcinogen.
    Therefore based upon this risk assessment, there is reasonable 
certainty that no harm will result from aggregate exposure to 
halosulfuron-methyl residues resulting from current and proposed uses.
    2. Infants and children. FFDCA section 408 provides that EPA may 
apply an additional safety factor (up to 10) in the case of threshold 
effects for infants and children to account for pre-natal and post-
natal toxicity and the completeness of the data base. Except for the 
pending request for a developmental neurotoxicity study, the toxicity 
data base is complete for halosulfuron-methyl.
     The chronic RfD was determined to be 0.1 mg/kg/day based upon the 
chronic dog study. The percent of RfD occupied is 0.9% for the most 
sensitive population subgroup, children (1-6 years old). The DWLOC for 
chronic exposure for infants and children is 1,000 [mu]g/L and is 
significantly greater than the maximum concentration of halosulfuron-
methyl in drinking water (0.008 [mu]g/L in ground water and 1.1 [mu]g/L 
in surface water).
     Based upon reliable toxicity data, the use of an additional 10X 
safety factor is not warranted. Dietary assessments do not indicate a 
level of concern for potential risks to infants and children based upon 
the low use rates of halosulfuron-methyl, and the results of field and 
animal RAC studies conclude that detectable residues are not expected 
in human foods.
     Therefore, based on complete and reliable toxicity data and the 
conservative exposure assessment, it is concluded that there is 
reasonable certainty that no harm will result to infants and children 
from aggregate exposure to halosulfuron-methyl residues with respect to 
the proposed new uses on dry and succulent snap beans.

F. International Tolerances

     Maximum residue levels have not been established for residues of 
halosulfuron-methyl on any food or feed crop by the Codex Alimentarius 
Commission.
