- The Clean Water Act
- The EPA TMDL Lawsuit
- The TMDL Rule
2The Clean Water Act
- Originated as the Water Pollution Control Act
(WPCA) of 1948 - WPCA amendments in 1970 created the EPA
- WPCA Amendments of 1972 became what is commonly
known as the Clean Water Act (CWA) today
3So what exactly is the Clean Water Act?
4Basic CWA Premise
- It is the national goal of water quality which
provides for the protection and propagation of
fish, shellfish, and wildlife and provides for
recreation in and on the water - It sets fishable, swimmable goals
5Water Quality Standards
- Authorizes the regulatory requirements governing
the Water Quality Standards program
6Important Sections of the Clean Water Act
- 303(d) - requires all states to develop a list of
their states impaired waterbodies that do not
meet state regulatory water quality standards. - States must establish priority rankings for these
waters and develop TMDLs based on their priority
rankings.
7Important Sections of the Clean
Water Act
- 305(b) - provides EPA with
- a description of the water quality of all
navigable waters in the state - an assessment of the status of waters of the
state with regard to their support of
recreational activities and fish and wildlife
propagation - an assessment of the state's water pollution
control activities toward achieving the CWA - an estimate of the costs and benefits of
implementing the CWA - a description of the nature and extent of
nonpoint sources of pollution and recommendations
for programs to address nonpoint source
pollution.
8The CWA Its more than just the water quality
standards
- Establishes Grants for Pollution Control Programs
- Establishes Nonpoint Source Management Program
- Establishes National Estuary Program (including
Barataria-Terrebonne National Estuary Program) - National Pollutant Discharge Elimination System
(NPDES) - mainly point source permitting
9If TMDLs have been a provision of federal law
since 1972, why the sudden focus?
- Concept ahead of technology science
- 1996 TMDL LAWSUIT
101996 TMDL Lawsuit
- Environmental groups sued the EPA and Regulatory
Agencies in 38 states claiming TMDLs were not
being completed in a timely manner - THE ENVIRONMENTAL GROUPS WON!!!

15Other Factors in TMDL ImplementationThe
Federal TMDL Rule
- A Federal Rule is a set of regulations as to how
a law will be implemented - The highly criticized TMDL Rule was published
July 13, 2000
16The Federal TMDL Rule(Continued)
- Some two dozen parties challenged the rule in
court in August 2000 - Because of the controversy, Congress prohibited
EPA from putting the rule into effect by denying
funds for that purpose
17The Federal TMDL Rule(Continued)
- On December 26, 2002, the EPA announced its
intention to withdraw the rule because of the
unworkable nature of the regulations - Since then, the rule has been revised but never
published for public review
18How Will Withdrawal of the TMDL Rule Affect
(your state)?

- Surface Water Quality Standards Assessment
- TMDLs
- Nonpoint Source Programs
20Water Quality Standards
- Where did those water quality standards come
from? The facts of life - In its basic form, a standard is a use and
criteria to protect that use.
21Does (your state) have its own set of Water
Quality Rules?
- Yes- WQS are provisions of (your state) State Law
- Authorized by the (your state) Water Control Law
- Goal is to preserve, protect and enhance
- The natural resources of (your states) aquatic
ecosystems - Public health and welfare
- The quality of waters for their designated uses
22What are Louisianas Designated Uses?
- (your state) WQS define 8 uses for surface waters
- Primary Contact Recreation (PCR)
- Secondary Contact Recreation (SCR)
- Fish Wildlife Propagation (FWP)
- Drinking Water Supply (DWS)
- Shellfish Propagation (SFP)
- Agriculture (AGR)
- Outstanding Natural Resource (ONR)
- Limited Aquatic/Wildlife Use (LAW)
23Does EPA have a Role in (your states) Water
Quality Standards?
- Yes - EPA reviews States water quality standards
- Yes - EPA approves or disapproves States water
quality standards - Yes - EPA Administrator may promulgate States
standards if - New standards not consistent with applicable
requirements of the CWA - A new or revised standard is necessary to meet
CWA requirements
24Role of WQS in Water Quality Management A Big
Framework
- Set and revise water quality standards in State
waters - Determine use attainment with Water Quality
Inventory, 305(b) report and 303(d) list of
impaired waters - Establishes endpoints for Total Maximum Daily
Loads (TMDLs), Waste Load Allocations (WLAs) and
Load Allocations (LAs) - Establish permit limits
25Are Standards Developed for Point Sources?
- Yes Point Sources are required to have National
Pollution Discharge Elimination System (NPDES)
permits issued by DEQ - Permit limits are set based on water quality
standards or available technology
26Surface Water Quality Monitoring Program
27Surface Water Quality Monitoring Program
- (your state) has had a surface water quality
monitoring program since the (year) - (Add your state information regarding sampling)
- EX Prior to 1998, sampled about 185 sites each
month on 70-80 waterbodies
28Add your state map with waterbodies
The Problem? (your state) has over ? named
waterbodies
29Surface Water Quality Monitoring Program
- All monitored subsegments in the targeted basins
are sampled monthly - The new rotating basin system increased the
number of sites monitored from (add your state
numbers here) across the state - Approximately ? sites are sampled each month
- In addition, ? long-term sites on ? waterbodies
are sampled monthly, not subject to rotation
30Surface Water Quality Monitoring Program

- Sediment related 291
- Low DO 309
- Nutrients 335
- Oil Grease 7
- Mercury 173
- Pesticides 76
- 39 different suspected impairments in total
36Louisiana Impairments (Fecal Coliform/Pathogens)
Add your states impairments and descriptions here
- Term used to describe bacteria found in the
intestinal tract of warm-blooded animals - If fecal material is present in excessive
concentrations, the potential for pathogens, such
as E. Coli can be present. - Fecal material also contains nitrogen and
phosphorous and can result in nutrient
over-enrichment of water bodies causing algae
blooms and oxygen depletion
37Louisiana Impairments (Sedimentation)
- Comes from agricultural sources, construction
sites and other soil disturbing activities in
urban settings - Increases the turbidity of water
- Reduces light penetration, altering the oxygen
relationships for certain aquatic organisms - Nutrients such as nitrogen and phosphorous and
certain pesticides may enter streams with
sediment - Harmful effects may include rapid algae growth
and fish kills from oxygen depletion
38Louisiana Impairments (Organic Enrichment/Low DO)
- Dissolved oxygen comes from several sources
including natural sources such as algae - Dissolved oxygen is also generated from water
that flows at high velocities over rocks and
other terrain - There are also substances such as organic matter,
dead plant and fecal material which reduce oxygen
concentrations (also known as oxygen demanding
substances) - Water quality criteria establish DO levels of 3-5
ppm to support the propagation of fish - Many Louisiana (your state) streams have low flow
conditions and high water temperatures during the
summer months
39In Louisiana, many water bodies do not meet
nationally derived water quality standards due to
naturally occurring physical, chemical, and
biological factors. This is especially true for
dissolved oxygen

(Add an example of a primary cause of impairment
from your state.)
40Louisiana Impairments (Nutrients)
- Generally refers to nitrogen and phosphorus, but
would include any element or compound essential
for the operation of a living system - Impairment levels for nutrients are not
established in the Louisiana water regulations
for Louisiana water bodies - Louisiana, like most states, has narrative, but
not numeric, criteria for nutrients (LAC
33IX.1113.B.8)
41Nutrient Criteria are currently being developed
for regions in Louisiana (not just watersheds)
- Will be water body-type specific
- Lakes and reservoirs
- Rivers and streams
- Estuaries
- Coastal marine waters
- Tidally influenced waters
- Wetlands
42EPA has published some default national numeric
criteria recommendations for N, P, chlorophyll a,
and turbidity
- EPA and USGS are statistically deriving default
numeric criteria using data from 14 ecoregions
across the US - EPA encourages states to develop their own
methods (following EPAs guidance or other
defensible methods) in formulating numeric
nutrient criteria.
43LDEQs Nutrient Criteria Development Plan for
Louisiana
- LDEQ is committed to using its
own ecoregional framework to develop
water body-specific, ecoregional nutrient
criteria for Louisianas water bodies - LDEQ is drafting an updated plan to be submitted
to EPA Region 6 for the end of 2004
44Louisiana Impairments (Metals)
- Enter the environment through human activity and
natural occurrences - Sources include industrial activities, combustion
of fossil fuels, and atmospheric deposition
(evaporating into the atmosphere and returning to
the ground as a result of gravity or rainfall - Metals of concern include
45Most Prominent Suspected Sources of Impairment
- Unknown sources (largely metals, chlorides, and
sulfates) - Natural sources (largely related to low DO,
chlorides and sulfates) - Municipal sewage treatment, septic tanks and
other fecal coliform sources - Agriculture

- Scientific assessment of the chemical, physical,
biological, and economic factors affecting the
attainment of designated uses in a water body
70Biological Factors for UAAs
- Fish and macroinvertebrates (aquatic insects,
snails, etc) are collected from streams - Samples are sorted and counted to determine
number of different species and population size - Results are compared to reference or Ecoregion
streams to determine support of UAA needs
71UAAs Approved by EPA

72Effect of TMDLs on Existing Sources
- Dischargers will have to upgrade their WWTPs to
advanced secondary or tertiary treatment. - New sources may not be allowed to discharge or
may be forced to locate in other watersheds. - Nonpoint source loadings must be reduced 30 -
90 to meet D.O. criterion.
73(Your states)Nonpoint Source Program
74NPS Management Strategy
- A balanced approach to management combining
statewide education and watershed implementation - An interagency committee of federal, state and
local entities working collectively to solve
(your states) nonpoint source pollution - Annual Reporting on progress made in
implementation and water quality improvement
75Goal of Programs
- Increase the Level of BMP Implementation within
the Watershed - Measure the Effectiveness of BMPs in Reducing
Pollutant Loads at the Field Level and the
Sub-Watershed Level - Monitor Water Quality on the 4-year Rotating
Basin Cycle in order to Determine if Water
Quality is Improving
