Availability of Draft NPDES General 

Permits MAG580000 and NHG580000 

for Discharges From Publicly Owned 

Treatment Works Treatment Plants 

(POTW Treatment Plants) and Other 

Treatment Works Treating Domestic 

Sewage in the Commonwealth of 

Massachusetts and the State of New 

Hampshire 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice. 

SUMMARY: The Director of the Office of 

Ecosystem Protection, EPA–New 

England, is issuing a notice of 

availability for public comment of the 

draft National Pollutant Discharge 

Elimination System (NPDES) general 

permits for certain Publicly Owned 

Treatment Works Treatment Plants 

(POTW treatment plants) and Other 

Treatment Works Treating Domestic 

Sewage (collectively, ‘‘facilities’’) in the 

Commonwealth of Massachusetts 

(including both Commonwealth and 

Indian country lands) and the State of 

New Hampshire. Throughout this 

document, these two permits are 

collectively referred to as the ‘‘Publicly 

Owned Treatment Works General 

Permit’’ (‘‘POTW GP’’ or the ‘‘General 

Permit’’). The draft General Permits, 

upon final issuance, will replace the 

prior POTW GP which expired on 

September 23, 2010. 

The draft POTW GP establishes 

Notice of Intent (NOI) requirements as 

well as effluent limitations, standards, 

and prohibitions for facilities that 

discharge to fresh and marine waters. 

Coverage under these General Permits is 

available to facilities in Massachusetts 

classified as minor facilities and to 

facilities in New Hampshire classified 

as major or minor facilities. Owners 

and/or operators of these facilities, 

including those facilities authorized to 

discharge under the current General 

Permit, will be required to submit an 

NOI to be covered by the reissued 

POTW GP to both EPA-New England 

and the appropriate State agency, in 

accordance with the notification 

requirements of the General Permit. 

Following EPA and the State review of 

the NOI, the facility will receive a 

written notification from EPA of permit 

coverage and authorization to discharge 

under the General Permit. The eligibility 

requirements for permit coverage, 

including the requirement that a facility 

have a receiving water dilution factor 

equal to or greater than 50, are provided 

in the General Permit. The General 

Permit does not cover new sources as 

defined under 40 CFR 122.2. 

The purpose of this document is to 

solicit public comments on the 

proposed General Permits. 

Public Comment Period: The public 

comment period is from November 4, 

2010 to December 6, 2010. Interested 

persons may submit written comments 

on the draft General Permit to the EPARegion I at the address listed below. 

Within the comment period, interested 

persons may also request, in writing, 

that EPA hold a public hearing pursuant 

to 40 CFR Section 124.12, concerning 

the draft General Permits. Such requests 

shall state the nature of the issues 

proposed to be raised at the hearing. A 

public hearing may be held at least 

thirty days after public notice whenever 

the Regional Administrator finds that 

response to this notice indicates 

significant public interest. In reaching a 

final decision on this draft permit, the 

Regional Administrator will respond to 

all significant comments and make 

responses available to the public at 

EPA’s Boston office. All comments and 

requests for public hearings must be 

postmarked or delivered before 

midnight December 6, 2010, the close of 

the public comment period. All public 

comments or requests for a public 

hearing must be submitted to the 

address below.

draft General Permit may be hand

Endocrine Disruptor Screening 

Program (EDSP); Announcing the 

Availability of a Draft for Weight-ofEvidence Guidance Document: 

Evaluating Results of EDSP Tier 1 

Screening To Identify Candidate 

Chemicals for Tier 2 Testing 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice. 

SUMMARY: EPA is announcing the 

availability for public review and 

comment of a draft guidance document 

titled, ‘‘Weight-of-Evidence Guidance 

Document: Evaluating Results of EDSP 

Tier 1 Screening to Identify Candidate 

Chemicals for Tier 2 Testing.’’ This 

action is in compliance with a directive 

from the House Appropriations 

Committee FY 2010 Report directing the 

EPA to develop and publish criteria by 

October 30, 2010, for evaluating results 

of Tier 1 screening and determining 

whether a chemical should undergo Tier 

2 analysis. The purpose of the weightof-evidence (WoE) document is to set 

forth some of the general principles, 

criteria, and considerations EPA 

generally believes to be relevant under 

a WoE approach for evaluating data 

submitted as part of EPA’s two-tiered 

paradigm for screening and testing 

chemicals for endocrine activity (i.e., 

estrogen, androgen, and thyroid 

hormonal systems; E, A, and T) under 

the EDSP. This document provides a 

transparent scientific approach for 

broadly evaluating Tier 1 screening data 

to detect an interaction with E, A, and/ 

or T hormonal systems and determine if 

additional Tier 2 testing is necessary. 

DATES: Comments must be received on 

or before January 3, 2011.
