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

accordance with procedures set forth in 40 CFR part 2. A copy of the 
comment that does not contain CBI must be submitted for inclusion in 
the public docket. Information not marked confidential will be included 
in the public docket without prior notice (including comments and data 
submitted electronically). The public docket and docket index, 
including printed paper versions of electronic comments that does not 
include any information claimed as CBI, will be available for public 
inspection in Rm. 119 at the address given above, from 8:30 a.m. to 4 
p.m., Monday through Friday, excluding legal holidays.

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.
