C.	Regulatory History

Creosote, one of the three “heavy duty wood preservatives” (the
others being the wood preservatives containing arsenic and/or chromium,
and Pentacholorphenol) was first registered in the United States in 1948
as a coal tar creosote active ingredient.  Presently, 13 products are
registered for use as industrial wood preservatives for above and below
ground wood protection treatments, as well as treating wood in marine
environments.  All 13 Creosote products are Restricted Use Pesticides;
12 are Ready-to-Use End-Use Products and 1 is a Manufacturing-Use
Product for formulating industrial end-use wood preservative products.
Creosote wood preservatives are used primarily in the pressure treatment
of railroad ties/crossties (about 70% of all Creosote use) and utility
poles/cross-arms (about 15 - 20% of all Creosote use).  Assorted
Creosote-treated lumber products (e.g., timbers, poles, posts and
ground-line support structures) account for the remaining uses for this
wood preservative.  The industry refers to different blends of Creosote
based on the wood treatment standards set by the American
Wood-Preservers’Association (AWPA).  For instance, P1/P13 and P2 are
the predominant blends used by the wood treating industry.  Typically,
railroad ties/crossties are treated with a P2 blend which is more
viscous than the P1/P13 blend typically used for treating utility poles.

In October 1978, an administrative review process was initiated to
consider 

whether the pesticide registration of the three heavy duty wood
preservative uses (including Creosote) should be canceled or modified. 
The Federal Register (Vol.49, No.139) of July 13, 1984 concluded that
process and announced that certain changes in the terms and conditions
of registration were required if registrants and applicants wished to
avoid cancellation.

After carefully evaluating the risks to public health posed by these
three heavy duty wood preservative chemicals (including Creosote) along
with the significant economic benefits resulting from their use, the
Agency determined that the use of Creosote as a wood preservative
chemical in accordance with certain modifications to terms of
registration would satisfy the statutory standard for registration. 
These modifications (classification as restricted use pesticide, workers
protection/protective clothing and equipment requirements, restricted to
non-residential uses, etc.) are noted in the Federal Register of January
13, 1986 (Vol.51, No. 7).

The Agency has announced and is currently processing a notice of receipt
of

requests by registrants of pesticide products containing creosote to
voluntarily cancel certain registrations and/or to amend to terminate
certain uses of affected products. Specifically, the five registrants
who are members of the Creosote Council III (Coopers Creek Chemical
Corporation, KMG-Bernuth, Inc.,  Koppers, Inc., Railworks Wood Products,
and Rutgers Chemicals AG) have requested in letters dated September 5,
2003 to cancel the registrations for their creosote non-pressure
treatment end-use products and/or to amend to terminate all non-pressure
treatment uses of other creosote products. These registrants are
requesting that the voluntary product cancellations and/or use
terminations become effective December 31, 2004. The registrants waived
all but 30 days of the 180-day comment period and have not requested any
existing stocks provision. At the request of a registrant, the Agency
published an extension to the public comment period on November 26,
2003, for an additional 30 days.  Unless a request is withdrawn by
December 26, 2003, the Agency intends to issue orders granting these
requests to cancel certain products, and to amend to terminate certain
uses.
