Petition to Modify or Revoke Tolerances

Federal Register: March 9, 2005 (Volume 70, Number 45) Pages 11646-11648

SUMMARY: EPA requests public comment during the next 60 days on a petition (available in docket ID number OPP-2005-0050) received from California, Connecticut, Massachusetts, and New York, requesting that the Agency modify or revoke all tolerances (maximum legal residue limits) for the pesticides alachlor, chlorothalonil, methomyl, metribuzin, and thiodicarb.

DCPA (Dacthal):
Notice of Request to Terminate Certain Uses

Federal Register: February 16, 2005 (Volume 70, Number 31) Pages 79389-7941

SUMMARY: DCPA is an herbicide used to control weeds on a large number of sites, including cole crops, onions, cotton, alfalfa, tomatoes, and turf.

Amvac, the registrant, requested termination of a number of uses in response to concerns about the prevalance and widespread contamination of ground water with DCPA and especially its metabolite tetrachloroterephthalic acid (TPA or di acid) which came to light when the tolerances for DCPA were being reassessed.

EPA identified a number of uses which can potentially contribute to ground water contamination, and Amvac responded with a proposal to delete these uses. In a letter dated December 15, 2004, Amvac requested that EPA amend its DCPA product registrations to terminate the following uses:

Alfalfa, Arracacha, Artichokes (Chinese and Jerusalem, ) Beans, Bean yam, Beets, Chestnuts (soil treatment and nursery stock,) Chufa, Citron melon, Cotton, Crabapples (soil treatment and nursery stock), Cucumber, Edible canna, Eggplant, Garlic, Ginger, Kale, Leren, Peas, Pepper, Potato, Residential turf and ornamentals, Squash (including pumpkin), Sweet potatoes Tanier, Turnip, Walnuts (non-bearing and nursery stock), Yam


Amvac has requested that the use terminations become effective April 1, 2005, and that it be allowed to sell existing stocks with labels including the uses proposed for termination until April 1, 2007.

Pentachloronitrobenzene (PCNB, Terraclor, Turfcide):
Availability of Risk Assessment [OPP-2004-0202; FRL-7697-1]

Federal Register: March 2, 2005 (Volume 70, Number 40) Pages 100908-10092

SUMMARY: PCNB is a fungicide used to control diseases on a number of field crops, turf, and ornamentals. Use sites include cole crops, green beans, cotton, potatoes, peanuts, lawns, golf courses, and sod farms. PCNB is applied to soil, foliage, and seeds.

EPA announces the availability of EPA’s revised risk assessments for the fungicide pentachloronitrobenzene (PCNB). In addition, this notice solicits public comment on risk reduction options for PCNB. The public also is encouraged to suggest risk management ideas or proposals to address the risks identified in the revised risk assessments. Risks of concern associated with the use of PCNB are: Concentrations of PCNB and its metabolites in drinking water which result in dietary risks, risk for residential handlers and postapplication risks to children and adults exposed to treated turf, risks to golfers, occupational risk for a large number of scenarios (for both seed treatment and non-seed treatment handlers), and excess ecological risks (particularly for aquatic organisms). The Agency is soliciting information, via targeting specific risks of concern, in effective and practical risk reduction measures.

2,4-Dichlorophenoxyacetic Acid (2,4-D):
Availability of Revised Risk Assessments and Preliminary Risk Reduction Options [OPP-2004-0167; FRL-7691-5]

Federal Register: January 12, 2005 (Volume 70, Number 8) Pages 2158-2160

SUMMARY: 2,4-D is a herbicide in the phenoxy family used for selective control of broadleaf weeds.

EPA is making available the Agency’s revised risk assessments, initially issued for comment through a Federal Register notice published on June 23, 2004 (69 FR 35019) (FRL–7362–7); responses to comments; and related documents for 2,4-D. EPA is releasing for public comment its preliminary risk reduction options for 2,4-D. EPA is providing an opportunity, through this notice, for interested parties to provide risk management proposals or otherwise comment on risk management for 2,4-D. Considering EPA’s preliminary risk reduction options, such comments and proposals should further discuss ways to manage 2,4-D’s potential drinking water and ecological risks resulting from its aquatic and terrestrial use, as discussed in the Agency’s risk assessments.

Rodenticides:
Availability of Revised Comparative Ecological Risk Assessment

Federal Register: September 22, 2004 (Volume 69, Number 183) Pages 56756-56758

SUMMARY: This notices announces the availability of the revised comparative ecological risk assessment and related documents for nine rodenticides, which includes those addressed in the Reregistration Eligibility Decisions (REDs) for zinc phosphide and the rodenticide cluster (brodifacoum, bromadiolone, bromethalin, chlorophacinone, and diphacinone), as well as three other rodenticides, warfarin, difethialone, and cholecalciferol. This notice also opens a 60-day public participation period during which the public is encouraged to submit risk management ideas or proposals. These actions are designed to further efforts to engage stakeholders in a dialogue on risk reduction and risk management.
