effect in humans that is similar to an 

effect produced by a naturally occurring 

estrogen, or such other endocrine effect 

as the Administrator may designate. In 

1996, EPA chartered a scientific 

advisory committee, the Endocrine 

Disruptor Screening and Testing 

Advisory Committee (EDSTAC), under 

the authority of FACA, to advise it on 

establishing a program to carry out 

Congress’ directive. EDSTAC 

recommended a multi-step approach 

including a series of screens (Tier I 

screens) and tests (Tier II tests) for 

determining whether a chemical 

substance may have an effect similar to 

that produced by naturally occurring 

hormones. EPA adopted almost all of 

EDSTAC’s recommendations in the 

program that it developed, the 

Endocrine Disruptor Screening Program 

(EDSP), to carry out Congress’ directive. 

EPA is in the process of developing 

and validating the screens and tests that 

EDSTAC recommended for inclusion in 

the EDSP. In carrying out this validation 

exercise, EPA is working closely with 

the Interagency Coordinating Committee 

for the Validation of Alternate Methods 

(ICCVAM) and other validation groups, 

as appropriate. EPA also is working 

closely with the Organization for 

Economic Cooperation and 

Development’s (OECD) Endocrine 

Testing and Assessment Task Force to 

validate and harmonize endocrine 

screening tests of international interest. 

Finally, to ensure that EPA has the 

best and most up-to-date advice 

available regarding the validation of the 

screens and tests in the EDSP, EPA 

chartered the Endocrine Disruptor 

Methods Validation Subcommmittee 

(EDMVS) of the National Advisory 

Council for Environmental Policy and 

Technology (NACEPT). The EDMVS 

convened nine meetings between 

October 2001 and December 2003. In 

2003, NACEPT recommended EDMVS 

become an Agency level 1 FACA 

Committee due to the complexity of the 

recommendations. The EDMVAC was 

chartered in 2004. The EDMVAC 

provides independent advice and 

counsel to the Agency on scientific and 

technical issues related to validation of 

the EDSP Tier I screens and Tier II tests, 

including advice on methods for 

reducing animal use, refining 

procedures involving animals to make 

them less stressful, and replacing 

animals where scientifically 

appropriate. EDMVAC and previous 

EDMVS meeting information and 

corresponding docket numbers are 

available electronically, from the EPA 

Internet Home Page at http:// 

www.epa.gov/scipoly/oscpendo/. You 

may also go to the EPA Docket at http://

II. Background 

The U.S. Environmental Protection 

Agency is convening two workshops to 

train stakeholders on how to report for 

the 2006 Partial Updating of the TSCA 

Chemical Substance Inventory. The EPA 

is required by section 8(b) of the Toxic 

Substances Control Act (TSCA) to 

compile and update an inventory of 

chemical substances manufactured or 

imported into the United States. Every 

four years, manufacturers (including 

importers) of certain chemical 

substances on the Chemical Substance 

Inventory have been required to report 

data specified in the TSCA section 8(a) 

Inventory Update Rule (IUR), 40 CFR 

part 710. Past updates included 

information on the chemical’s 

production volume, site-limited status, 

and plant site information. 

Amendments to the IUR promulgated in 

the Federal Register on January 7, 2003 

(68 FR 848) (FRL–6767–4) expanded the 

data reported on certain chemicals to 

assist EPA and others in screening 

potential exposures and risks resulting 

from manufacturing, processing, and 

use of TSCA chemical substances. At 

the same time, EPA amended the IUR 

regulations to increase the production 

volume threshold which triggers 

reporting requirements from 10,000 

pounds per year to 25,000 pounds per 

year and established a new higher 

threshold of 300,000 pounds per year 

above which manufacturers must report 

additional information on downstream 

processing and use of their chemical 

substances. The 2003 amendments to 

the IUR also revoked the exemption 

from reporting for inorganic chemical 

substances, provided a partial 

exemption from reporting of processing 

and use information for chemical 

substances of low current interest, and 

continued the current exemption from 

reporting for polymers, microorganisms, 

and naturally occurring chemical 

substances. These changes modify 

requirements for information collected 

in calendar year 2005 and submitted in 

2006 and thereafter. These workshops 

may be of interest to persons currently 

reporting under the IUR and to 

manufacturers of inorganic chemical 

substances. 

The workshops will include a series 

of presentations by representatives of 

EPA on the Instructions for Reporting 

for the 2006 Partial Updating of the 

TSCA Chemical Substance Inventory. 

Subjects discussed will include 

reporting requirements, instructions for 

completing the reporting form, how to 

assert confidentiality claims, how to 

submit completed reports to EPA, and 

case studies illustrating different aspects 

of reporting. During the workshops, 

persons in attendance will be able to ask 

questions regarding the material being 

presented. The purpose of these 

meetings is to provide training to 

persons who must report in 2006 under 

the Inventory Update Rule. 

III. How Can I Request to Participate in 

this Meeting?

meeting by directing your web browser

SUMMARY: The Director of the Caribbean 

Environmental Protection Division 

(CEPD), Environmental Protection 

Agency—Region 2 (EPA), is issuing 

Notice of a Draft National Pollutant 

Discharge Elimination System (NPDES) 

general permit for discharges from small 

municipal separate storm sewer systems

of Puerto Rico. This draft NPDES 

general permit establishes Notice of 

Intent (NOI) requirements, standards, 

prohibitions and management practices 

for discharges of storm water from 

municipal separate storm sewer

small MS4s that discharge storm water 

will be required to submit a NOI to 

EPA–CEPD to be covered by the general 

permit and will receive a written 

notification from EPA–CEPD of permit 

coverage and authorization to discharge 

under the general permit. The eligibility 

requirements are discussed in the draft 

permit. The municipality must meet the 

eligibility requirements of the permit 

prior to submission of the NOI. This 

general permit does not cover new 

sources as defined under 40 CFR 122.2. 

DATES: Public comments are due by 

midnight on February 6, 2006. The 

general permit shall be effective on the
