ENVIRONMENTAL PROTECTION AGENCY
[OPP-34152; FRL-6039-1]
Oryzalin: Amendment to the Reregistration Eligibility Decision
(RED)
AGENCY: Environmental Protection Agency (EPA).
ACTION: Amendment to the Oryzalin Reregistration Eligibility Decision
(RED) Document
-----------------------------------------------------------------------
SUMMARY: This notice amends the Oryzalin Reregistration Eligibility
Decision (RED) Document, Case 0186, pursuant to section 4(g)(2) of the
Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) 7 U.S.C. 136
et seq. This amendment revises the Personal Protective Equipment (PPE)
requirements established in the RED for handlers of oryzalin end-use
products. All handlers loaders of oryzalin liquid formulations will be
required to wear: chemical-resistant gloves, shoes, socks, long-sleeved
shirt, and long pants. In addition, mixers and loaders of liquid
formulations will be required to wear a chemical-resistant apron. PPE
for all other non-homeowner use scenarios will be determined based on
the toxicity of the end-use product, as per guidance provided by the
Worker Protection Standard (WPS). This notice does not apply to the
homeowner uses of oryzalin.
DATES: Written comments on the RED decisions must be submitted by
December 7, 1998.
ADDRESSES: Submit three copies of written comments identified with the
docket control number ``OPP-34152'' by mail to: Public Information and
Records Integrity Branch, Information Resources and Services Division

SUPPLEMENTARY INFORMATION:
Electronic Availability: Electronic copies of this document and
various support documents are available from the EPA home page at the
Federal Register-Environmental Documents entry for this document under
``Laws and Regulations'' (http://www.epa.gov/fedrgstr/).
EPA published a notice in the Federal Register of on March 8, 1995,
(60 FR 12763)(FRL-4940-6), announcing the availability of the Oryzalin
RED. In the RED, EPA provided its regulatory position on the registered
uses of oryzalin based on the information and data available at that
time. The RED set forth specific requirements for product
reregistration eligibility. The Agency required certain PPE (coveralls
over long-sleeved shirt and long pants,
[[Page 59994]]
chemical-resistant gloves, chemical-resistant footwear and chemical-
resistant headgear for overhead exposures) for all non-homeowner uses
of oryzalin. The RED also required a chemical-resistant apron for
mixers and loaders of all non-homeowner, end-use oryzalin liquid
products. The additional PPE were required to mitigate exposure to
oryzalin due to carcinogenicity concerns.
In the Oryzalin RED, the Agency used the Pesticide Handler Exposure
Database (PHED), Version 1.0, to derive exposure estimates for mixers,
loaders and applicators. In August 1995, DowElanco requested that the
Agency reconsider the additional PPE requirements. In responding to
this request, the Agency conducted a new risk and exposure assessment
using an updated version of this same database (PHED 1.1) that
contained more accurate information. The updated PHED database became
available after the Oryzalin RED document had been published. The
refined assessment indicated that the PPE requirements in the RED were
overly restrictive, however, the refined risk estimates still showed
that baseline PPE (i.e., long-sleeved shirt, long pants, socks and
shoes) were not adequately protective of mixers and loaders of the
liquid formulations and applicators using hand-held equipment.
For mixers and loaders of oryzalin liquids and applicators using
hand-held equipment, the Agency is now requiring, chemical-resistant
gloves, long-sleeved shirt, long pants, shoes, and socks. Additionally,
for mixers and loaders of oryzalin liquids, a chemical-resistant apron
is required. PPE for all other formulations will be determined based on
the acute toxicity of the end-use product, as per guidance provided by
the Worker Protection Standard (WPS).
For the low-pressure handwand use scenario, the refined oryzalin
exposure and risk assessment used the high-pressure handwand data set
rather than the low-pressure handwand data set. The Agency believes
that the high-pressure handwand data set more closely approximates the
type of spray equipment used to apply oryzalin to ornamentals and
turfgrass. The risk estimates for applicators with the high-pressure
handwand scenario were 3.5 x 10-5 with the baseline PPE and chemical-
resistant gloves, which is in the acceptable range for applicators.
