National Management Measures To Control Nonpoint Source Pollution 
From Hydromodification

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: EPA is requesting comment on draft technical guidance for 
managing nonpoint source pollution from hydromodification. The term 
hydromodification refers to an activity that alters the geometry and 
physical characteristics of a stream or river in such a way that the 
flow patterns change. This guidance is intended to provide technical 
assistance to states, territories, authorized tribes, and the public 
for managing hydromodification and reducing nonpoint source pollution 
of surface and ground water. The guidance provides background 
information about nonpoint source pollution from activities associated 
with channelization and channel modification, dams, and streambank and 
shoreline erosion. It discusses the broad concepts of assessing and 
addressing water quality problems on a watershed level, and it presents 
up-to-date technical information about how to reduce nonpoint source 
pollution from hydromodification. Implementation of the guidance will 
result in increased use of scientifically sound, cost-effective 
hydromodification management measures, and will support states in their 
efforts to implement their Nonpoint Source Control Programs.

B. What Should I Consider as I Prepare My Comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through 
http://www.regulations.gov or e-mail. Clearly mark the part or all of the 

information that you claim to be CBI. For CBI information in a disk or 
CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as 
CBI and then identify electronically within the disk or CD ROM the 
specific information that is claimed as CBI). In addition to one 
complete version of the comment that includes information claimed as 
CBI, a copy of the comment that does not contain the information 
claimed as CBI must be submitted for inclusion in the public docket. 
Information so marked will not be disclosed except in accordance with 
procedures set forth in 40 CFR part 2.
    2. Tips for Preparing Your Comments. When submitting comments, 
remember to:
     Identify the rulemaking by docket number and other 
identifying information (subject heading, Federal Register date and 
page number).
     Follow directions--The agency may ask you to respond to 
specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
     Explain why you agree or disagree; suggest alternatives 
and substitute language for your requested changes.
     Describe any assumptions and provide any technical 
information and/or data that you used.
     If you estimate potential costs or burdens, explain how 
you arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
     Provide specific examples to illustrate your concerns, and 
suggest alternatives.
     Explain your views as clearly as possible, avoiding the 
use of profanity or personal threats.
     Make sure to submit your comments by the comment period 
deadline identified.

II. Background

    In 1993, under the authority of section 6217(g) of the Coastal Zone 
Act Reauthorization Amendments, EPA issued Guidance Specifying 
Management Measures for Sources of Nonpoint Pollution in Coastal 
Waters. That guidance document details management measures appropriate 
for the control of five categories of nonpoint sources of pollution in 
the coastal zone: agriculture, forestry, urban areas, marinas and 
recreational boating, and hydromodification. The document also includes 
management measures for wetlands, riparian areas, and vegetated 
treatment systems because they are important to the abatement of 
nonpoint source pollution in coastal waters. States and territories 
were required to adopt measures ``in conformity'' with the coastal 
management measures guidance for their Coastal Nonpoint Pollution 
Control Programs.
    State, territory, and tribal water quality assessments continue to 
identify nonpoint source pollution as a major cause of degradation in 
surveyed waters nationwide. In 1987, Congress enacted section 319 of 
the Clean Water Act to establish a national program to control nonpoint 
sources of water pollution. Under section 319, states, territories, and 
tribes address nonpoint source pollution by assessing the nonpoint 
source pollution problems within the state, territory, or tribal lands; 
identifying the sources of pollution; and implementing management 
programs to control the pollution. Section 319 also authorizes EPA to 
award grants to states, territories, and tribes to assist them in 
implementing management programs that EPA has approved. Program 
implementation includes nonregulatory and regulatory programs, 
technical assistance, financial assistance, education, training, 
technology transfer, and demonstration projects. In fiscal year 2005, 
Congress appropriated and EPA awarded approximately $207 million for 
state nonpoint source management program grants.
    The 1993 management measures guidance focused on conditions of and 
examples from the coastal zone. The draft national management measures 
guidance is intended to expand the focus nationwide to provide 
technical guidance on effective measures for managing hydromodification 
for the abatement of nonpoint source pollution. Although the practices 
detailed in the 1993 coastal guidance apply generally to inland areas, 
EPA has recognized the utility of developing and publishing technical 
guidance that explicitly addresses nonpoint source pollution on a 
nationwide basis. Moreover, additional information and examples from 
research and experience to date with implementation of the management 
measures are available to enrich the national guidance. These changes 
have helped to prompt the revision and expansion of the 
hydromodification chapter of the 1993 guidance.

III. Scope of the Draft Hydromodification Guidance--Sources of Nonpoint 
Source Pollution Addressed

    The draft technical guidance continues to focus on the major 
sources of pollution from hydromodification identified for the 1993 
coastal guidance by EPA in consultation with a number of other Federal 
agencies and other leading national experts, including several experts 
from the U.S. Army Corps of Engineers. Specifically, the guidance 
identifies management measures for the following:
Channelization and Channel Modification
     Physical and Chemical Characteristics of Surface Water
     Instream and Riparian Habitat Restoration
     Dams
     Erosion and Sediment Control
     Chemical and Pollutant Control
     Protection of Surface Water Quality and Instream and 
Riparian Habitat
     Streambank and Shoreline Erosion
     Eroding Streambanks and Shorelines

IV. Approach Used To Develop Guidance

    The draft management measures guidance is based in large part on 
the 1993 coastal guidance. The coastal guidance was developed using a 
workgroup approach to draw upon technical expertise within other 
Federal agencies as well as state water quality and coastal zone 
management agencies.
    The 1993 text has been expanded to include information on the 
application and effectiveness of hydromodification BMPs from recent 
research, the cost of installing BMPs, watershed-scale and ecological 
impacts of hydromodification activities, and certification programs for 
personnel involved in construction and dam removal.

V. Request for Comments

    EPA is soliciting comments on the draft guidance on nonpoint source 
management measures for hydromodification. The Agency is soliciting 
additional information and supporting data on the measures specified in 
this guidance and on additional measures that may be as effective or 
more effective in controlling nonpoint source pollution from 
hydromodification. EPA requests that commenters focus their comments on 
the technical soundness of the draft management measures guidance.
