SUPPLEMENTARY INFORMATION:

I. Background

    The Department of Labor, as part of its continuing effort to reduce
paperwork and respondent (i.e., employer) burden, conducts a
preclearance consultation program to provide the public with an
opportunity to comment on proposed and continuing information
collection requirements in accord with the Paperwork Reduction Act of
1995 (PRA-95) (44 U.S.C. 3506(c)(2)(A)). This program ensures that
information is in the desired format, reporting burden (time and costs)
is minimal, collection instruments are clearly understood, and OSHA's
estimate of the information collection burden is accurate. The
Occupational Safety and Health Act of 1970 (the OSH Act) (29 U.S.C. 651
et seq.) authorizes information collection by employers as necessary or
appropriate for enforcement of the Act or for developing information
regarding the causes and prevention of occupational injuries,
illnesses, and accidents (29 U.S.C. 657). The OSH Act also requires
that OSHA obtain such information with minimum burden upon employers,
especially those operating small businesses, and to reduce to the
maximum extent feasible unnecessary duplication of efforts in obtaining
information (29 U.S.C. 657).
    The Slings Standard (29 CFR 1910.184) specifies several collection
of information (paperwork) requirements, depending on the type of sling
(paragraph (e) of the Standard covers alloy steel chain slings;
paragraph (f) covers wire rope slings; paragraph (g) covers metal mesh
slings; paragraph (h) covers natural and synthetic fiber-rope slings;
and paragraph (i) covers synthetic web slings).
    The purpose of each of these requirements is to prevent workers
from using defective or deteriorated slings, thereby reducing their
risk of death or serious injury caused by sling failure during material
handling. The information on the identification tags, markings, and
codings assist the employer in determining whether the sling can be
used for the lifting task. The sling inspections enable early detection
of faulty slings. The inspection and repair records provide employers
with information about when the last inspection was done and about the
type of repairs made. This information provides some assurance about
the condition of the slings. These records also provide the most
efficient means for an OSHA compliance officer to determine that an
employer is complying with the Standard. Proof-testing certificates
give employers, workers, and OSHA compliance officers assurance that
the slings are safe to use. The certificates also provide the
compliance officers with an efficient means to assess employer
compliance with the Standard.

II. Special Issues for Comment

    OSHA has a particular interest in comments on the following issues:
     Whether the proposed information collection requirements
are necessary for the proper performance of the Agency's functions,
including whether the information is useful;
     The accuracy of OSHA's estimate of the burden (time and
costs) of the information collection requirements, including the
validity of the methodology and assumptions used;
     The quality, utility, and clarity of the information
collected; and
     Ways to minimize the burden on employers who must comply;
for example, by using automated or other technological information
collection and transmission techniques.

III. Proposed Actions

    OSHA is proposing to increase the existing burden hour estimate for
the collection of information requirements specified by the Standard
from 20,001 hours to 24,181, a total increase of 4,180 hours. This
increase in burden hours is a result of an adjustment in the number of
slings (from 1,116,667 to 1,350,000).
    Type of Review: Extension of a currently approved collection.
    Title: Slings (29 CFR 1910.184).
    OMB Control Number: 1218-0223.
    Affected Public: Business or other for-profits; Not-for-profit
organizations; Federal Government; State, Local, or Tribal Government.
    Number of Respondents: 1,350,000.
    Frequency of Response: On occasion.
    Total Responses: 297,676.
    Average Time per Responses: Varies from 1 minute (.02 hour) to
maintain a certificate to 30 minutes (.50 hour) for a manufacturing
worker to acquire information from a manufacturer for a new tag, make a
new tag, and affix it to a sling.
    Estimated Total Burden Hours: 24,181.
    Estimated Cost (Operation and Maintenance): $0.

1 UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WASHINGTON, D. C. 20460 OFFICE OF PREVENTION, PESTICIDES AND TOXIC SUBSTANCES MEMORANDUM SUBJECT: ORYZALIN TRED: Estimated Drinking Water Concentrations for Oryzalin for Use in the Human Health Drinking Water Risk Assessment. PC Code: 104201 DP Barcodes: D209537 FROM: Iwona Maher, Chemist Sid Abel, Branch Chief Pat Jennings, Risk Assessment Process Leader Environmental Risk Branch 1 Environmental Fate and Effects Division ( 7507C)

TO: Thurston Morton, Chemist Reregistration Branch IV Health Effects Division ( 7509C)

Gary Mullins, Chemical Review Manager Reregistration Branch III Special Review and Reregistration Division ( 7508C)

Attached is the EFED drinking water assessment for the tolerance reassessment for oryzalin and the data evaluation records for two soil adsorption/ desorption studies ( MRIDs: 43433201 and 43433202; Appendix III) submitted by the registrant. Oryzalin was first registered in 1974. A Registration Standard was issued in June, 1987 ( NTIS# PB89 102396) and an oryzalin Reregistration Eligibility Decision ( RED) was issued in September 1994.

Oryzalin is a pre emergent, surface applied herbicide used to control many annual grasses and certain broad leaf weeds. Its agricultural uses include berries, vine and orchard crops ( i. e., citrus fruits, pome and stone fruits, and tree nuts) and non agricultural uses include ornamentals, Christmas trees, non bearing fruit and nut trees, non bearing vineyards and berries, and established warm season turf. 2 Tier II PRZM/ EXAMS modeling was performed to estimate the drinking water concentrations for the human health dietary risk assessment. Estimated environmental concentrations were based on modeling a subset of the agricultural use scenarios to capture oryzalin's crop and non crop use spectrum, regional differences between the west and east coast, and the differences in method of applications and formulation. The scenarios that were modeled are California almonds ( ground and aerial application), North Carolina apples ( ground application), Florida citrus ( ground application), Oregon Christmas trees ( ground application), and Pennsylvania turf ( granular application via broadcast spreader). The most conservative estimates were obtained for ground application of oryzalin to Florida citrus at the maximum labeled annual application rate on 12 lb a. i./ acre, applied twice annually at 6 lb a. i./ acre with an interval between applications of 60 days. For the purpose of estimating acute risks, the predicted 1 in 10 year annual peak concentration of oryzalin in drinking water from surface water is 198 ppb. For evaluating chronic non cancer concerns, the estimated 1 in 10 year annual mean concentration of oryzalin in drinking water is 12.7 ppb. For evaluating concerns for cancer, the 36 year annual mean concentration is 9.2 ppb. This assessment was based on the incorporation of oryzalin shortly after application. Both acute and chronic concentrations for all other scenarios were significantly lower.

SCI GROW modeling predicted ground water concentrations of oryzalin at the annual application rate of 12 lb a. i./ acre ( i. e., two applications of 6 lb a. i./ acre) of 0.93 ppb in drinking water from shallow ground water sources. This concentration may be considered as both the acute and chronic upper bound value for use in the human health risk assessment. 3 Drinking Water Assessment for the Tolerance Reassessment of Oryzalin Use on Multiple Crops PC Code 104201 I. SUMMARY AND CONCLUSIONS Oryzalin is a pre emergent, surface applied herbicide used to control many annual grasses and certain broad leaf weeds. The herbicide was first registered in 1974. A Registration Standard was issued in June, 1987 ( NTIS# PB89 102396). Prior to the issuance of the Registration Standard, several agricultural crops were deleted. The only food crop groups remaining on oryzalin labels are berries, vine and orchard crops ( i. e., citrus fruits, pome and stone fruits, and tree nuts). In addition, oryzalin has many non food uses including ornamentals, Christmas trees, non bearing fruit and nut trees, non bearing vineyards and berries, and established warm season turf. An Oryzalin Reregistration Eligibility Decision ( RED) was issued in September 1994.

Formulations of oryzalin include: granular, wettable powder, water dispersible granulars, flowable concentrate and liquid. All liquid formulations can be applied by ground broadcast application, band application, or chemigation. Additionally, aerial application is labeled in California. Dry ( granular) formulations are applied via broadcast spreader. To estimate the drinking water concentrations for human health dietary risk assessment, Tier II PRZM/ EXAMS modeling was performed for use on California almonds ( ground and aerial application), North Carolina apples ( ground application), Florida citrus ( ground application), Oregon Christmas trees ( ground application), and Pennsylvania turf ( granular via broadcast spreader) with soil incorporation shortly after application . The most conservative surface water estimates were obtained for ground application of oryzalin to Florida citrus at the maximum annual application rate on the label of 12 lb a. i./ acre, applied twice annually at 6 lb a. i./ acre with an interval between applications of 60 days. For the purpose of estimating acute risks, the predicted 1 in 10 year annual peak concentration of oryzalin in drinking water from surface water is 198 ppb. The simulated 1 in 10 year annual mean ( chronic non cancer) and 36 year annual mean ( chronic cancer) concentrations 4 of oryzalin in drinking water are 12.7 ppb and 9.2 ppb, respectively. Both acute and chronic concentrations for all other scenarios were significantly lower including the scenario of aerial application on California almonds.

SCI GROW modeling predicted a concentration of oryzalin uses at the annual application rate of 12 lb a. i./ acre ( i. e., two applications of 6 lb a. i./ acre) as 0.93 ppb in drinking water from shallow ground water sources. This concentration may be considered as both the acute and chronic upper bound value for use in the human health risk assessment.

Ground and surface water concentrations were not estimated for the major degradate of oryzalin, 4 hydroxy 3,5 dinitrosulfanilamide ( OR 20). Laboratory fate studies indicate that OR 20 has an average half life of 58 days with K ads ranging from 0.165 to 0.310. These data would indicate the potential to underestimate environmental exposures should OR 20 be toxicologically important.

Based on laboratory data, oryzalin is moderately persistent and mobile in sandy soil with low organic matter content. The chemical is stable to hydrolysis and appears to be susceptible to rapid direct photolysis in water with a half life of 1.4 hrs. Therefore, it is not expected to persist in clear shallow surface waters exposed to sunlight. On the soil surface oryzalin appears to photodegrade rather rapidly with a half life of 3.8 days. Under aerobic conditions oryzalin biodegrades slowly, with a half life of 2.1 months. Under anoxic conditions it undergoes reduction more readily, with a half life of 10 days. Based on terrestrial field dissipation studies, it appeared to be moderately persistent under field conditions, its dissipation half lives ranged from 58 to 77 days.

Oryazlin appears to have a greater potential to contaminate surface water via spray drift than via runoff to nearby surface water. According to the McCall classification ( McCall et al., 1980), oryzalin appears to be mobile in sand and sandy loam, relatively mobile in loam, and immobile in clay loam. It is probably unlikely that oryzalin would reach ground water. However, in sandy soils and under some environmental conditions, such as excess precipitation, or where soil preferential flow conditions exist and exposure to sunlight is minimal, oryzalin residues may leach into ground water. If oryzalin reaches ground water, it probably will readily undergo reduction to more polar compounds.

Some of oryzalin degradates formed in aerobic soil metabolism may potentially leach into ground water. The major degradate, 4 hydroxy 3,5 dinitrosulfanilamide ( OR 20), is very mobile and moderately persistent and, therefore, has a potential for leaching. Oryzalin degradates were not monitored under field conditions.

Fate and transport data for oryzalin were sufficient to characterize drinking water exposure. Only, the aerobic and anaerobic aquaticc metabolism studies were not submitted. Fate data submitted for oryzalin degradates were limited to two soil adsorption/ desorption studies. If there are human and/ or ecotoxicological concerns associated with oryzalin degradates, a new terrestrial field dissipation and/ or more comprehensive laboratory data for oryzalin degradates may be requested.

II. USAGE PROFILE 5 Oryzalin is a selective pre emergent, surface applied, herbicide from the dinitroaniline family. The herbicide is used to control annual grasses and many broadleaf weeds in citrus, fruit and nut trees, berries, vineyards, turf, ornamentals and Christmas tree plantations. It is manufactured in granule, wettable powder, water dispersible granule, flowable concentrate and liquid. Liquid formulations are applied via ground broadcast application, band application, aerial application, and chemigation. Granular formulation is applied via broadcast spreader. The pre emerged herbicide is soil incorporated via ½  1 inch of rainfall, sprinkler irrigation or a shallow cultivation of 1 2 inches within 21 days. Table 1 provides label information for these crop and non crop uses that were selected for modeling purposes. 6 Table 1.

APPROACH TO DRINKING WATER ASSESSMENT A drinking water assessment for parent oryzalin was conducted for three agricultural scenarios: CA almonds, NC apples, and FL citrus. Oryzalin was applied via aerial ( CA almonds only) and ground application at the maximum rate of 12 lb ai/ acre annually with two applications of 6 lb a. i./ acre. Additionally, the assessment was performed for two non agricultural scenarios: PA golf course turf at a maximum annual ground application rate of 6 lb ai/ acre with three application of 2 lb a. i./ acre, and OR Christmas trees at a maximum annual ground application rate of 8 lb ai/ acre with two application of 4 lb a. i./ acre. This assessment was based on oryzalin incorporation shortly after application.

Tier II modeling employing PRZM EXAM was performed to estimate drinking water concentrations from surface water sources and the SCI GROW model was used to predict drinking water concentrations of oryzalin from ground water sources.

IV. ENVIRONMENTAL FATE SUMMARY The major route of oryzalin disappearence is aqueous photolysis, photodegradation on soil surface, and reduction under anaerobic condition. Oryzalin appears to degrade slowly under aerobic soil conditions and is stable to hydrolysis. Under field conditions oryzalin appeared to be moderately persistent, with a half life of about two months.

Oryzalin has the potential to contaminate surface water via spray drift. If there is little or no exposure to sunlight, runoff may contribute to the surface water contamination in the event of significant rainfall occurring after application prior to soil incorporation. Although oryzalin does not appear to be mobile under field conditions, the soil/ water partition coefficients indicate that chemical mobility will vary from mobile to immobile depending on soil type and organic matter content. Oryzalin is less likely to contaminate ground water resources due to reduction in the 7 anaerobic soil layer. However, in sandy soils under some environmental conditions, such as excess precipitation, or where soil preferential flow conditions exist and exposure to sunlight is minimal, oryzalin residues may leach into ground water and undergo reduction to more polar compounds.

Laboratory studies indicate that oryzalin is stable to hydrolysis ( MRID 41378401) but exhibits susceptibility to rapid direct aqueous photolysis; the aqueous photolytic half life is 1.4 hours ( MRID 41288701). The chemical also readily photodegrades on the soil surface with an extrapolated half life of 3.8 days ( sunlight equivalent nonlinear half life, MRID 41050001).

Oryzalin degrades aerobically with a half life of 63 days in sandy loam soil ( MIRD 41322801). Out of nine metabolites formed, three ( 4 hydroxy 3,5 dinitrosulfanilamide ( OR 20), 2 ethyl 7 nitro 1 propyl 1H benzimidazole 5 sulfonamide 3 oxide ( UN 2), and the unidentified compound UN 3; MRID 43433202) appeared to be very mobile. Others were relatively mobile or immobile. Under anaerobic conditions oryzalin nitro groups undergo reduction to amines, dealkylation, and ring formation to produce benzimidazoles, with a half life of 10 days ( MRID 41322802). Major anaerobic metabolites are 7 amino 2 ethyl 1 propyl 1H benzimidazole 5 sulfonamide ( i. e., OR 14; 10.3% of time zero radioactivity) and 7 amino 2 ethyl 1H benzimidazole 5 sulfonamide ( i. e., OR 16; 5.3 % of time zero radioactivity). The highly polar degradation products are associated with soil organic matter. Soil binding of oryzalin residues appears to be an important route of dissipation. In an aerobic soil metabolism study, oryzalin non extractible residues ( i. e., parent and metabolites) increased to 63.1% of time zero radioactivity at six months posttreatment ( PTT) and to 70.6% of time zero radioactivity at 60 days PTT in an anaerobic study. Formation of CO 2 and/ or volatile degradation products was not a major route of dissipation for oryzalin in both aerobic and anaerobic metabolism studies.

Substantial quantities of oryzalin could also be available for runoff for a few days to months postapplication depending on the degree of exposure to sunlight ( photodegradation on soil half life of 3.8 days; aerobic soil half life = 2.1 months; terrestrial field dissipation half lives of 77 146 and 58 138 days). The low to intermediate soil/ water partitioning of oryzalin ( K d = 2.1, 4.9, 8.4, and 12.9; MRID 41479802) indicates that fractions of oryzalin could be organic carbon transported via both dissolution in runoff water and adsorption to eroding soil. Based on its resistance to abiotic hydrolysis coupled with only a moderate susceptibility to aerobic and anaerobic biodegradation indicate that it will be somewhat more persistent in receiving surface waters that are deeper, have high light attenuation, low microbiological activities and long hydrological resident times.

While it appears that most of the applied oryzalin either binds to soil or degrades, some oryzalin degradates may have high potential for leaching. Parent oryzalin would be most mobile in coarse, wet, alkaline soils with little organic matter. However, parent oryzalin would not be stable if it was to leach into groundwater. Anaerobic conditions below the soil surface would result in reduction of the compound to more polar degradates. At least three oryzalin degradates, OR 20, UN 2 and UN 3, formed in aerobic soil metabolism ( MRID 43433202), have the potential to leach into ground water. The major degradate ( MIRD 41322801), OR 20, is moderately persistant and has a very high potential for leaching. The degradate appears to be very mobile in sand, sandy loam, and loam soils, with Freundlich K ads values ranging from 0.165 to 0.310 ( MRID 43433201). Under aerobic conditions, in different soils, OR 20 appears to degrade with the 8 average half lives ( t 1/ 2) of 58 days ( based on a formation decline curve; Tables IX through XII, 163 1, MRID 43433202) and 102 days ( based on a formation decline curve; 162 1, MRID 41323801). Apparent K d values for UN 2 ranged from 0.89 4.52 L/ kg and for UN 3 ranged from 1.50 4.85 L/ kg with the exception of 12.19 L/ kg in the sand soil ( MRID 43433202). The OR 20 degradate and other degradates have not been monitored in the field. Their persistence in natural waters is unknown.

In the field, oryzalin appears to degrade slowly with a half life of 68 days in Florida sand soil and a first phase half life of 58 in California loam soil and 77 days in Michigan silty clay loam soil. The second phase half lives were 138 days in California loam soil and 146 days in Michigan silty clay loam soil. Parent oryzalin did not appear to be mobile under field conditions. The parent was undetectable and always less than detection limits ( i. e., 0.01 ppm; MRID 42138001) below 12 inches of soil depth. Oryzalin degradates were not monitored in the field dissipation studies submitted.

Based upon its relatively low to intermediate soil/ water partitioning, significant fractions of the oryzalin in receiving surface waters should exist both dissolved in the water column and adsorbed to suspended and bottom sediment. The reported BCFs for oryzalin ( 32X to 106X) indicate that the bioaccumulation potential of oryzalin is relatively low.

V. DRINKING WATER ASSESSMENT Monitoring data for oryzalin in surface water and ground water were not found. Oryzalin is not included in National Water Quality Assessment ( NAWQA) Program, USGS. Concentrations of oryzalin in surface water and ground water were estimated via modeling.

Surface Water Assessment For the drinking water assessment, a Tier II PRZM EXAMS ( PRZM 3.12 and EXAMS 2.975) modeling simulation was performed using the index reservoir ( IR) scenario and the percent cropped area ( PCA) adjustment factor for the uses of oryzalin selected for non crops ( i. e., golf courses and Christmas trees) and crops ( i. e., almonds, citrus, and apples) that would result in the highest estimated environmental concentrations from the available combinations of crop and location. For apples and almonds, label instructions propose oryzalin to be ground applied twice at 6 lbs ai/ acre with a 2.5 month interval between applications. For citrus, label instructions were the same as for appleas and almonds except the interval between applications was 60 days. The California almonds scenario in which oryzalin was aerially applied simulated thee applications of 3.9 lbs a. i./ acre with 90 day intervals between applications. The Christmas tree scenario simulated two applications of 4 lbs ai/ acre with a 2 month interval between applications. The golf course scenario simulated three applications of 2 lbs ai/ acre with a 3 month interval between applications per proposed label.

Oryzalin is a surface applied herbicide in citrus, fruit and nut trees, berries, vineyards, turf, ornamentals and Christmas tree plantations. The pre emergent herbicide is soil incorporated via ½  1 inch of rainfall or sprinkler irrigation or a plowed to a depth of 1 2 inches within 21 days 9 after application. For the purpose of modeling it was assumed that soil incorporation was achieved via 1 inch of rainfall immediately after application for all crops except for turf, where granular formulations are soil applied and default soil incorporation depth of 4 cm, with concentration linearly decreasing with depth selected ( CAM = 1).

A graphical interface shell ( April 5, 2002), the pe3. pl program, was used to facilitate putting chemical and use specific input values into the proper positions in the PRZM input and the EXAMS chemical files. Tables 2 and 3 list the modeling input parameters. The PRZM/ EXAMS output files for oryzalin uses on golf courses, Christmas trees, almonds, citrus, and apples are presented in Appendix I. 10 Table 2.

The estimated drinking water concentrations for all other uses were significantly lower.

For evaluating acute concerns, the highest simulated 1 in 10 year annual peak concentration of oryzalin in drinking water was 198 ppb in Florida citrus index reservoir scenario adjusted with a default PCA factor of 0.87 in the absence of a specific PCA value for citrus. For evaluating chronic non cancer concerns, the simulated 1 in 10 year annual mean concentration of oryzalin in drinking water was determined to be 12.7 ppb. For evaluating concerns for cancer, the 36 year annual mean concentration was determined to be 9.2 ppb in the same scenario. Table 4 presents all simulated surface water concentrations of oryzalin for crop and non crop uses adjusted for a default PCA factor of 0.87.

Because oryzalin can be used on a broad spectrum of berries, vine and orchard crops and has several non crop uses in some regions it may be applied to multiple crops and non crops within a single watershed. In general, the likelihood that multiple crops will be found within single watersheds where oryzalin is used is unknown and therefore specific PCA adjustment factors were not used and each scenario was adjusted with the default PCA of 0.87. Potential to underestimate environmental concentrations may be associated with the application of the default PCA when uses on turf grass are co located with the other non crop uses and crop uses.

Within each scenario a change of oryzalin application dates or rainfall pattern may influence the modeling results. Oryzalin application dates where selected based on each crop and non crop profile and their planting dates from the PRZM crop scenarios. In some instances this information was based on information gathered from regional Pesticide Information Offices or regional Herbicide scientists.

B. Ground Water Assessment According to the McCall classification ( McCall et al., 1980), oryzalin appears to be mobile in sand and sandy loam, relatively mobile in loam, and immobile in clay loam. Oryzalin Kd values are 2.1, 4.9, 8.4, and 12.9 L kg o. c. 1 ( MRID 41479802). Under some environmental conditions oryzalin may reach vulnerable ground water resources. Open literature data suggests that oryzalin would be most mobile in coarse, moist, alkaline soils with little organic matter content ( Jacques and Harvey, 1979a; Helling, 1976). In a field dissipation study, oryzalin generally was undetectable and always less than detection limits ( ppm) below 12 inches of soil depth. Oryzalin degradates were not monitored in the field. An aged soil adsorption/ desorption study ( non guideline study, MRID 43433202) indicates that, out of nine oryzalin degradates studied, at least three are potentially very mobile to mobile depending on soil type. These degradates are 4 hydroxy 3,5 dinitrosulfanilamide ( OR 20; K d = 0.56 6.38 L/ kg), 2 ethyl 7 nitro 1 propyl 1H benzimidazole 5 sulfonamide 3 oxide ( UN 2; K d = 0.89 4.52 L/ kg), and the unidentified [ 14C] compound UN 3, with a K d ranging from 1.50 4.85 L/ kg except 12.19 L/ kg in the sand soil. Another adsorption/ desorption study conducted with OR 20 degradate also confirmed that, according to McCall classification, OR 20 is very mobile with Koc values ranging from 23.41 to 47.69 ( MRID 43433201). The drinking water modeling was conducted for parent oryzalin only.

The SCI GROW screening model was used to estimate ground water concentrations of oryzalin. The model estimates the upper bound ground water concentrations of pesticides likely to occur when the pesticide is used at the maximum allowable rate in areas where ground water is particularly vulnerable to contamination. Table 5 lists the input parameters used to model concentrations of oryzalin in ground water.

Aerobic Soil Metabolism t1/ 2 63 days MRID 41322801 ( GLN 162 1) 1   the median of four K oc values ( 840, 700, 933, 1290) was used The highest estimated concentration of oryzalin in drinking water from shallow ground water sources is 0.93 µ g/ L for application on almonds, apples, and citrus at 6 lb a. i./ acre applied 2 times per year. This concentration may be considered as both the acute and chronic upper bound value for use in the human health risk assessment.

Assumptions and Uncertainties SCI GROW was developed using K oc values ranging from 32 180 L/ Kg. Extrapolation beyond these values further increases the uncertainty of the ground water EECs. The K oc input value for oryzalin was 887 L/ kg o. c. Given that the K oc of oryzalin is outside the range of the K oc values used to develop SCI GROW, there is uncertainty regarding the estimated ground water concentrations such that the model may overestimate concentrations.

Some of oryzalin's degradates appear to be much more mobile than the parent and therefore, may have the potential to reach ground water resources. In particular, degradate 4 hydroxy 3,5 dinitrosulfanilamide, appears to be moderately persistent and very mobile, and has the potential to reach ground water resources via leaching in all soil types and under all conditions. Oryzalin degradates were not monitored in field studies. The drinking water environmental concentration 14 estimates were performed only for the parent. If human toxicological concerns are determined to be associated with any of the mobile oryzalin degradates, a drinking water assessment would need to be conducted for the degradate of concern. 15 VI.

DEPARTMENT OF ENERGY

Federal Energy Regulatory Commission

[Project No. 2503-154]

Duke Energy Carolinas, LLC; Notice of Availability of Draft
Environmental Assessment

    In accordance with the National Environmental Policy Act of 1969
and the Federal Energy Regulatory Commission's (Commission)
regulations, 18 CFR part 380 (Order No. 486, 52 FR 47897), the Office
of Energy Projects has reviewed the application for a new license for
the Keowee-Toxaway Hydroelectric Project, located on the Toxaway,
Keowee, and Little Rivers in Oconee County and Pickens County, South
Carolina and Transylvania County, North Carolina, and has prepared a
draft Environmental Assessment (EA) for the project. The project does
not occupy federal land.
    The draft EA contains staff's analysis of the potential
environmental impacts of the project and concludes that relicensing the
project, with appropriate environmental measures, would not constitute
a major federal action that would significantly affect the quality of
the human environment.
    A copy of the draft EA is on file with the Commission and is
available for public inspection. The draft EA may also be viewed on the
Commission's Web site at http://www.ferc.gov using the ``eLibrary''
link. Enter the docket number, excluding the last three digits in the
docket number field, to access the document. For assistance, contact
FERC Online Support at<EMAIL_ADDRESS>or toll-free at 1-
