Review of the National Ambient Air 

Quality Standards for Lead; Proposed 

Rulemaking 

AGENCY: Environmental Protection 

Agency. 

ACTION: Advance notice of proposed 

rulemaking. 

SUMMARY: The Environmental Protection 

Agency is initiating a review of the 

primary and secondary national 

ambient air quality standards (NAAQS) 

for lead. This action is required by 

provisions of the Clean Air Act (CAA) 

as amended. 

ADDRESS: Docket No. A-83-22, which 

will contain material relevant to this 

standard review, is located in the 

Central Docket Section of the U.S. 

Environmental Protection Agency, West 

Tower Lobby, Gallery I, 401 M Street,

629-5655. 

SUPPLEMENTARY INFORMATION: On 

October 5,1978 (43 FR 46246), the 

Environmental Protection Agency 

promulgated national ambient air 

quality standards for lead under section 

109 of the Clean Air Act. 42 U.S.C. 7409. 

The primary (health-based) and 

secondary (welfare-based) standards 

were set at a level of 1.5 micrograms 

lead per cubic meter of air (jug Pb/m3), 

averaged over a calendar quarter. 

As indicated in previous Federal 

Register notice (47 FR 15643,17665, 

31751, 47668, 56551), EPA is now 

reviewing, updating, and revising the air 

quality criteria document for lead, 

pursuant to sections 108(c) and 109(d) of 

the Clean Air Act, 42 U.S.C. 7408(c) and 

7409(d). Release of the first draft of the 

revised criteria document was 

announced September 26,1983 in the 

Federal Register (48 FR 43724). The draft 

has undergone review by interested 

members of the public and the Clean Air 

Scientific Advisory Committee (CASAC) 

of EPA's Science Advisory Board. 

Comments submitted on the draft 

document and heard at the April 26-27, 

1984 CASAC meeting (49 FR 13916) are 

now being analyzed by EPA's 

Environmental Assessment and Criteria 

Office (ECAO) for necessary revisions 

to the draft. EPA will provide notice 

through the Federal Register of the 

status and availability of other 

documents related to the review of the 

lead standards. The public will be 

provided opportunities to comment 

through public meetings and/ or written 

comments. 

Major issues under consideration in 

this standard review include: 

1. Critical effect level—Recent studies 

suggest that relatively low-level 

exposure to lead may adversely affect 

cognitive development and 

neurobehavioral function in young 

children. The demonstration of such 

effects may require reevaluation of the 

rationale upon which the current 

primary standard is based to insure that 

the standard provides an adequate 

margin of safety to protect public health. 

2. Multi-media considerations—The 

natural presence of lead in the 

environment combined with human 

activities in the refining and use of the 

metal have resulted in widespread 

exposure to lead from various media. As 

with the current primary standard, the 

relative contribution of atmospheric 

lead, both direct and indirect, to body 

burden will continue to be an important 

issue in the review of the NAAQS. 

3. Air quality data—Lead air quality 

monitoring performed since the 

promulgation of the current standards 

reflects a significant downward trend in 

atmospheric lead that correlates closely 

with the reduction of lead in gasoline. 

The data have recently been critized, 

however, as not being representative of 

actual human exposure. At issue will be 

the appropriate role for such data in the 

evaluation of exposure. 

4. Risk assessment—The lead 

standards review may include, the first 

formal application of the NAAQS risk 

assessment program, which has been 

under development for several years. A 

CASAC Subcommittee on Risk 

Assessment has been formed to advise 

EPA on the planning and conduct of the 

lead risk assessment. The first meeting 

of the Subcommittee was held 

September 14-15,1983. The importance 

of the lead risk assessment as a factor in 

the review of the primary standard will 

depend in part on the results of the 

review by the CASAC and its 

subcommittee.

Texas &tea tol&pand the capacity of 

Transco's CTGS from approximately 

369,000 Mcf per day to 1,119,000 Mcf per 

day. It is further stated that such parties 

had acquired the rights to purchase 

quantities of gas produced from various 

offshore Texas blocks located in the 

vicinity of Transco's CTGS and 

therefore sought to expand the capacity 

of that system to enable the system to 

accommodate the quantities of gas 

anticipated to be delivered from such 

blocks. 

It is stated that on July 15,1982, the 

Commission issued a certificate of 

public convenience and necessity 

authorizing the construction and 

operation of a segment of the PCTL 

consisting of approximately 30.12 miles 

of 30-inch loop line extending from a 

junction platform in Brazos Block 538 to 

Cities Service Company's A production 

platform in Brazos Block A-76, offshore 

Texas, (the Offshore Loop) and certain 

measuring and regulating facilities at the 

Markham Plant onshore Texas. It is 

noted that authorization of the 

remainder of the PCTL is still pending 

before the Commission in Docket No. 

CP82-158-CC0. 

In order for Southern to attach gas 

reserves committed to it in Brazos Block 

A-47, offshore Texas, which are located 

in the vicinity of the proposed PCTL, it 

is stated that Southern has agreed to 

purchase an ownership interest in the 

PCTL sufficient to accommodate the 

quantities of gas it anticipates would be 

delivered from Brazos Block A-47. If so 

authorized by the Commission, 

Applicants propose to reallocate the 

ownership interests and capacity 

entitlements of the various parties in the 

PCTL (including the Offshore Loop) as 

follows: 

Transco 

Tennsssse

6.6667 

2.1333 

2.1333 

Applicants note that Transco's 

presently authorized 48.1333 percent 

ownership interest in the PCTL includes 

the 2.1333 percent interest attributable 

to the portion of the Brazos Block A-47 

reserves which are now committed to 

Southern and the proposed ownership 

percentages therefore reflect a reduction 

in Transco's ownership interest 

corresponding to the percentage 

ownership interest which Southern 

seeks to acquire. 

Any person desiring to be heard or to 

make any protest with reference to said 

amendment and petition should onor 

before September 14,1983, file with the 

Federal Energy Regulatory Commission, 

Washington, D.C. 20426, a mottion to 

intervene or a protest in accordance 

with the requirements of the 

Commission'o Rules of Practice and 

Procedure (18 CFR 385.214 or 385.211) 

and the Regulations under the Natural 

Gas Act (18 CFR 157.10). All protests 

filed with the Commission will be 

considered by the it in determining the 

appropriate action to be taken, but will 

not serve to make the protestants 

parties to the proceeding. Any person 

wishing to become a party to a 

proceeding or to participate as a party in 

any hearing therein must file a motion to 

intervene in accordance with the 

Commission's Rules. All persons who 

have heretofore filed need not file again.

Take notice that Wyoming Interstate 

Company, Ltd. (WIC) on August 16, 

1983, tendered for filing certain 

proposed changes to (1) the (Schedule of 

Shippers and List of Contract Demands 

and (2) Rate Schedule T of its FERC Gas 

Tariff, Original Volume No. 1. 

Rate Schedule T is a two-part rate 

under which WIC provides firm 

transportation service to its 

jurisdictional customers (Shippers). WIC 

intends to place its Cheyenne 

Compressor Station in service on 

October 1,1983, to provide increased 

system capacity necessary to meet its 

Shippers' increased nominations which 

will also become effective on that date 

as reflected in the revised Schedule of 

Shippers and List of Contract Demands. 

WIC's proposed revisions to Rate 

Schedule T reflects the annualized effect 

of the additional investment in gas plant 

for the installation of compression as 

authorized by the Commission's order in 

Docket No. CP79-80, et al., Opinion No. 

138. 

WIC proposes that the tariff revisions 

become effective on October 1,1983.

Draft General National Pollutant 

Discharge Elimination System Permit 

for Portions of Deep Seabed Mining 

Exploration Activities in the Pacific 

Ocean 

AGENCY: Environmental Protection 

Agency. 

ACTION: Notice of Draft General Permit. 

SUMMARY: The Environmental Protection 

Agency (EPA) Regional Administrator of 

Region 9 is today providing notice of a 

draft general National Pollutant 

Discharge Elimination System (NPDES) 

permit for certain discharges from 

vessels or other floating craft subject to 

the Deep Seabed Hard Mineral 

Resources Act (DSHMRA) engaged in 

deep seabed mining exploration 

activities under the DSHMRA in the 

Pacific Ocean. This draft general permit 

establishes effluent limitations, 

standards, prohibitions and other 

conditions on discharges from these 

activities, except for any discharge from 

the initial mining tests which is not 

covered by this permit. The area to be 

covered by this general permit, when 

issued, is located within that portion of 

the deep seabed in the Pacific Ocean 

between 110 degrees West and 180 

degrees West longitude and 5 degrees 

North and 20 degrees North latitude. 

This draft general permit is based on 

the administrative record available for 

public review in Region 9 of the 

Environmental Protection Agency. The 

fact sheet sets forth the principal facts 

and the significant factual, legal, and 

policy questions considered in the 

development of the draft permit. The 

terms of the permit are also discussed in 

the fact sheet. A copy of the fact sheet is 

reprinted and the draft permit can be 

obtained at the address given below. 

DATES: Comment Period.—Interested 

persons may submit comments on the 

draft general permit and administrative 

record to the Regional Administrator, 

Region 9 at the address below no later 

than October 20,1983. 

Public Hearing.—The Hearing Officer 

designated by the Regional 

Administrator will conduct a public 

hearing on October 6,1983, in the 

Nevada Room (6th floor), Region 9, U.S. 

Environmental Protection Agency, 215 

Fremont Street, San Francisco, 

California 94105, beginning at 10:00 a.m., 

Pacific time, until all persons have been 

heard. 

ADDRESS: Comments should be sent to

FACT SHEET AND SUPPLEMENTARY 

INFORMATION 

I. Background 

A. General Permits 

Section 402 (33 U.S.C. 1342) of the 

Federal Water Pollution Control Act, as 

amended (33 U.S.C. 1251 et-seq.) (the 

Clean Water Act (CWA)) authorizes 

EPA to issue NPDES permits for the 

purpose of regulating the discharge of 

pollutants to navigable waters. 

Section 301(a) of the CWA (33 U.S.C. 

1311(a)) provides that the discharge of 

pollutants is unlawful except in 

accordance with a NPDES permit. EPA's 

regulations authorize the issuance of 

general NPDES permits to categories of 

dischargers (40 CFR 122.28). EPA may 

issue a single general permit to a 

category of point sources located within 

the same geographic area whose 

discharges warrant similar pollution 

control measures. The Director of an 

NPDES permit program (in this case the 

Regional Administrator) is authorized to 

issue a general NPDES permit, according 

to criteria contained in 40 CFR 

122.28(a)(2)(ii), if there are a number of -

point sources operating in a geographic 

area that: 

1. Involve the same or substantially 

similar types of operations; 

2. Discharge the same types of wastes; 

3. Require the same effluent 

limitations or operating conditions; 

4. Require the same or similar 

monitoring requirements; and 

5. In the opinion of the Director, are 

more approporiately controlled under a 

general permit than under individual 

permits. 

As in the case of individual permits, 

violation of any condition of a general 

NPDES permit constitutes a violation of 

the CWA and subjects the discharger to 

the penalties specified in Section 309 of 

the CWA (33 U.S.C. 1319). Any owner or 

operator authorized to discharge by a 

general permit may be excluded from 

coverage by applying for an individual 

permit. This request may be made by 

submitting a NPDES permit application 

together with the reasons supporting the 

request to the Regional Administrator. 

In addition, the Regional Administrator 

may require any person who is 

authorized to discharge under this 

general permit to apply for and obtain 

an individual permit. Any interested 

person may petition the Regional 

Administrator to take this action. 

However, an individual NPDES permit 

will not be issued for a deep seabed 

mining exploration facility to be covered 

by this general NPDES permit unless it 

can be demonstrated that inclusion 

under the general permit is clearly 

inappropriate. The Regional 

Administrator may consider the 

issuance of individual permits according 

to the criteria in 40 CFR 122.28(b)(2). 

These include: 

1. The discharge(s) is a significant 

contributor of pollution; 

2. The discharger is not in compliance 

with the terms and conditions of the 

general permit; 

3. A change has occurred in the 

availability of demonstrated technology 

or practices or the control or abatement 

of pollutants applicable to the point 

source; 

4. Effluent guidelines are subsequently 

promulgated for the point sources 

covered by the general permit; 

5. A Water Quality Management Plan 

containing requirements applicable to 

such point source is approved; or 

6. The requirements listed in 40 CFR 

122.28(a) and identified in the previous 

paragraphs are not met. 

However, changes in pollutant control 

or abatement technology, effluent 

guidelines, or water quality standards 

affecting a large number of the covered 

point sources may be more 

appropriately addressed through 

modification, or revocation and 

reissuance of the final general permit. 

B. Deep Seabed Mining Exploration 

Activities in the Pacific Ocean 

Manganese nodules containing nickel, 

cobalt, manganese and copper have 

been the subject of commercial interest 

for nearly 25 years. In 1980, the Deep 

Seabed Hard Mineral Resources Act 

(DSHMRA) (30 U.S.C. 1401 et seq.) was 

enacted. The DSHMRA authorized the 

National Oceanic and Atmospheric 

Administration (NOAA) to issue 

licenses for exploration to Untied States 

citizens after July 1,1981. In preparation 

of issuance of licenses for exploration, 

in September 1981 NOAA issued deep 

seabed mining regulations for 

exploration licenses at 15 CFR Part 970, 

a final Programmatic Environmental 

Impact Statement (PEIS) and a final 

Technical Guideance Document.(TGD). 

Section 109(e) of the DSHMRA (30 

U.S.C. 1419(e)) provides that any 

discharge of a pollutant from a vessel or 

other floating craft subject to the 

DSHMRA is subject to the provisions of 

the Clean Water Act. EPA has advised 

NOAA of its intention to issue a general 

NPDES permit to cover deep seabed 

mining exploration activities which are
