TMDL implementation involves actions to be taken across
agricultural, forest, urban, and rural residential land uses to
reduce pollutants and improve water quality. This web site is
intended to provide information to help Designated Management
Agencies implement TMDLs for nonpoint source pollution. Most
links provide information applicable to any nonpoint source TMDL. Contact the appropriate
basin coordinator for further information regarding TDMLs.
One of the first steps for improving water quality after a TMDL is
completed is to develop a TMDL Implementation Plan. DEQ has
named certain federal, state, and local governments and agencies,
including cities, counties, and special districts as DMAs because
these agencies and governments have authority to manage and regulate
sources of pollutants that are listed in the TMDL. The following are
various documents that can assist in the development of an
Implementation Plan. Several documents are working drafts that will
be updated over time based on feedback from DMAs.
Implementation Plan Guidance
This document provides guidance to state and local government
designated management agencies on developing and implementing
sector-specific or source-specific Total Maximum Daily Load
implementation plans that are required by OAR 340-042-0080(3) to
address nonpoint sources of pollution.
Implementation Tracking Matrix
DOC (Appendix D of Implementation Plan Guidance above)
This is a template for DMAs to describe and report management
activities in their annual reports to ODEQ.
Management Strategy Checklist
This document identifies some key management strategies that all
plans should consider for various water quality parameters.
Many Designated Management Agencies are likely to have
management strategies developed and described in other documents.
This check list will help you reference what has been developed and
evaluate the adequacy of existing programs. If gaps are identified,
this check list will help DMAs address the deficiencies.

There are a variety of management measures that can be used in
developing Implementation Plans. The following are state or national
sources of information which may be helpful in identifying actions
to take. They are organized by nonpoint source or pollutant type.
Polluted Runoff - Nonpoint Source Pollution by Category
Federal and local management measures and other information
available for 8 categories of Nonpoint Source Pollution-Agriculture,
Forestry, Hydro/Habitat Modification, Marinas, Mining, Roads, Urban
and Wetland/Riparian Management.
Sources of bacteria include discharges of untreated or poorly
treated sewage resulting from malfunctions or overflows, and runoff
that carries feces from pets or wildlife.
Mercury is a potent neurotoxin that can cause damage to the brain
and nervous system. Primary sources of mercury in the Willamette
Basin are associated with nonpoint sources, namely the erosion of
soils containing mercury and runoff from atmospherically-deposited
The primary sources of nutrients are fertilizers (nitrogen) and soil
Riparian management (Temperature)
In both urban and rural areas, increased solar radiation can result
from removal of riparian (streamside) vegetation which reduces the
amount of shade over the water and increases stream temperature.
Riparian Monitoring and Restoration
Riparian Model Ordinances
Frequent sources of sediment are construction sites and roads.
Roads and Construction
Stormwater management is meant to reduce many pollutants from point
sources and nonpoint sources.

Model Development Code and User's Guide for Small Cities
Developed by Oregon's Transportation and Growth Management Program
at the request of Oregon's small cities. It is intended to assist
small cities in updating their ordinances to be consistent with
state planning policies, statutes, and administrative rules, while
providing options for implementing "smart development" practices.
The Water Quality Model Code and Guidebook Model
A companion to the Model Development Code and User's Guide for Small
Cities. Developed by the Department of Land Conservation and
Development and the Department of Transportation under the
Transportation and Growth Management Program (TGM). This guidebook
integrates many of the "smart development" inspired code
recommendations of the TGM project with recommended code language to
achieve water quality objectives. Where the two objectives do not
overlap, the author has tried to assure that there would be no
This is a short list of funding sources. More information about each
of these sources is available on the Boise State University

Environmental Protection Agency grants
Boise State University
Watershed Planning Tool developed by the Environmental Finance
Center at Boise State University that helps organizations determine
their funding needs to meet the goals and objectives of their
Watershed Program Plan, and provides a vast database of private and
public funding sources. The database is easy to search and useful to
small jurisdictions or grass roots organizations.
Oregon Department of Environmental Quality
- Nonpoint Source Water Quality
Control (319) Grants
Grant funds available through Section 319 of the Water Quality Act
of 1987 are a critical element in turning Oregon's NPS control
program into water quality protection realities in watersheds
throughout the state. ODEQ solicits proposals each year in October.
- Clean Water State Revolving Fund
Nonpoint projects are eligible, as long as they have a water quality
benefit, are sponsored by public entities, and demonstrate ability
to pay back the loan. Amounts and terms vary but interest rates are
well below levels of inflation. A portion of the SRF program may be
considered match to 319 grants. Example programs include: conversion
of open agriculture irrigations ditch to a piped system; City of
Portland riparian restoration/land purchase.

identified in the Willamette Basin TMDL.
Cost Estimate to Restore Riparian Forest Buffers and Improve Stream
Habitat in the Willamette
This report describes cost estimates to reduce nonpoint source
pollution in the Willamette Basin from restoring riparian
vegetation. It was submitted to the EPA for the 2008 Clean Watershed Needs Survey.
OWEB Restoration Priorities - Willamette Basin
Watershed restoration summaries were developed using work plans and
restoration priorities that were developed by local watershed
councils. They were compiled for each subbasin in the Willamette
- Willamette Priorities - DEQ (under development)
This 4-page document provides background information on the water
quality issues in the Willamette Basin, the perceived solutions, and
restoration projects needed to improve water quality. This will be
used to help direct 319 grant proposals.
Fact sheets on TMDL implementation in the Willamette
Southern Willamette Valley Groundwater Management Area
Implementing the TMDL requires consideration of groundwater
management because of the close link between groundwater and surface
water, especially regarding bacteria and nutrients.
