SUPPLEMENTARY INFORMATION:

Background. The Commission in 1967 

assigned stream quality objectives (also 

called ‘‘criteria’’) for pH to all tidal and 

non-tidal interstate streams in the 

Delaware River Basin (‘‘basin’’). Since 

that time, scientists’ understanding of 

natural fluctuations in freshwater and 

saltwater pH levels has grown. 

Likewise, the development and 

application of pH criteria have evolved, 

while the Commission’s pH stream 

quality objectives have remained 

unchanged. Commission scientists in 

consultation with experts from DRBC 

member states and federal agencies have 

evaluated the pH criteria adopted by 

signatory states and recommended by 

federal agencies over the past four-anda-half decades. They have concluded 

that in order to minimize regulatory 

inconsistencies and better address 

natural pH cycles in the main stem 

Delaware River, two classes of revisions 

to the Commission’s criteria for this 

shared interstate waterway should be 

considered. The first concerns the range 

of pH levels deemed to comprise the 

numeric standard within the tidal and 

non-tidal zones of the main stem and 

tidal portions of tributaries. The second 

concerns excursions outside the 

standard range that are attributable to 

natural conditions. The proposed 

revisions were unanimously endorsed 

by the Commission’s Water Quality 

Advisory Committee (‘‘WQAC’’) in 

March 2009. The WQAC is a standing 

committee of stakeholders, including 

regulators, municipal and industrial 

dischargers, academicians and

environmental organizations that 

advises the Commission on technical 

matters relating to water quality within 

the basin. 

Proposed Change to Existing Criteria. 

The Commission’s existing pH criteria 

applicable to the main stem are 

expressed as ranges. ‘‘Between 6.0 and 

8.5’’ is the range currently assigned to 

all freshwater (non-tidal) zones of the 

main stem Delaware River—DRBC 

Water Quality Zones 1A through 1E. In 

all tidal zones—DRBC Water Quality 

Zones 2 through 6, which include the 

tidal main stem and tidal portions of its 

tributaries—the pH range currently in 

effect is ‘‘between 6.5 and 8.5’’. The 

proposed amendments would make 6.5 

the lower threshold of acceptable pH 

conditions for all water quality zones 

encompassing reaches of the main stem 

and tidal portions of its tributaries. 

Natural Conditions Clause. The 

proposed amendments would add a 

clause to the pH criteria recognizing 

natural deviations outside the 6.5 to 8.5 

pH range in the moderately acidic 

waters draining the Catskill Mountains 

and Pocono Plateau, the high-light and 

high-productivity zones of the non-tidal 

main stem, and the acidic coastal plain 

tidewaters of the Delaware Estuary. 

Proposed Rule Text. In accordance 

with these proposed changes, the pH 

criteria for Water Quality Zones 1A 

through 1E (non-tidal main stem) and 2 

through 6 (tidal main stem and tidal 

portions of tributaries) are proposed to 

be amended to read, ‘‘Between 6.5 and 

8.5 inclusive, unless outside this range 

due to natural conditions.’’ The affected 

sections of the Commission’s Water 

Quality Regulations consist of 

subsection C.3 of each of sections 2.20.2 

through 2.20.6, respectively, for Water 

Quality Zones 1A through 1E (non-tidal 

main stem); and sections 3.30.2 through 

3.30.6, respectively, for Water Quality 

Zones 2 through 6 (tidal main stem and 

tidal portions of tributaries). It is further 

proposed to amend paragraph 410.1(c) 

of title 18 of the Code of Federal 

Regulations by replacing the date of 

incorporation by reference that appears 

there (currently, December 8, 2010), 

with the date on which the Commission 

adopts a final rule in response to this 

proposal. 

Dated: September 17, 2013.

SUPPLEMENTARY INFORMATION: Pursuant 

to the National Environmental Policy 

Act of 1969, codified at 42 U.S.C. 4321– 

4370f, Department of Homeland 

Security Management Directive 023–01, 

and Commandant Instruction 

M16475.1D, we are making available to 

the public our FEIS assessing the 

potential environmental impacts 

associated with a proposed final rule to 

regulate discharges of dry cargo residue 

in the Great Lakes. 

In August 2008, the Coast Guard 

issued an Environmental Impact 

Statement (the Phase I FEIS), which 

evaluated regulatory alternatives for 

discharging DCR into the Great Lakes. 

Based in part on that FEIS’s findings, we 

published an interim rule on September 

29, 2008 (73 FR 56492). It kept in place 

the Coast Guard’s interim enforcement 

policy for Great Lakes DCR discharges 

and announced our intention to 

research Phase I FEIS data gaps related 

to DCR discharge control measure costs 

and effectiveness. 

The Phase II FEIS we are now making 

available is ‘‘tiered’’ off the Phase I 

FEIS, addresses the Phase I FEIS data 

gaps, and would provide support for a 

Coast Guard final rule to take the place 

of the 2008 interim rule. It finalizes the 

Phase II draft EIS that we made 

available for public comment when we 

issued a supplemental notice of 

proposed rulemaking (77 FR 44528; Jul. 

30, 2012) to propose the final rule. The 

Phase II FEIS reviews data we collected 

from approximately 2,000 DCR 

reporting forms and 30 Coast Guardobserved dry cargo loading and 

unloading operations. Data collected 

permitted further evaluations of DCR 

quantities and the effectiveness of 

control measures. The Phase II FEIS 

analysis concludes that the final rule 

would require maintaining a ‘‘broomclean’’ standard on the vessel deck and 

implementing a management plan to 

minimize DCR discharges from a 

vessel’s deck and tunnel. Vessels would 

need to keep onboard records of DCRrelated discharges and continue 

observing existing DCR discharge 

exclusion areas. Mitigation of nearshore 

and port impacts would be included 

through a prohibition of limestone and 

clean stone DCR discharges within 3 

statute miles of shore. In the Western 

Basin of Lake Erie, vessels not traveling 

beyond 3 statute miles from shore could 

discharge DCR within dredged 

navigation channels and not create 

adverse impacts to native sediment or 

benthos. 

We encourage you to submit 

comments or related material on the 

FEIS. Please include your personal 

contact information so we can contact 

you if we need to follow up. All 

comments received will be posted 

without change to http://

www.regulations.gov and will include 

any personal information you have 

provided. Anyone can search http://
