Clean Air Act (CAA) Overview
purpose: control air pollution
titles
stationary sources
mobile sources
acid rain
permitting program for major sources
stratospheric ozone depletion
established criteria air pollutants (6 identified)
SO2 (sulfur dioxide)
CO (carbon monoxide)
PM (particulate matter)
NOX (nitrogen oxides)
Pb (lead)
O3 (ozone)
*main focus of CAA from 1970 - late 1990’s
Resource Conservation and Recovery Act (RCRA) (1976)
what are hazardous wastes?
3 criteria
must be solid waste as defined by RCRA
garbage, refuse, ash, liquids, gas
must be waste
any material that is abandoned/discarded
any inherently waste-like material that should be discarded
must be hazardous waste as defined by RCRA
listed in EPA regulations or
hazardous characteristics
ignitability, corrosive, reactive, toxic
mixture rule
derived from rule
Comprehensive Environmental Response, Compensation and Liability Act (CERCLA)
response to love canal
first major law addressing leaking/inactive/abandoned sites
short term emergency response
long term cleanup
remedial, not regulatory
applies to things that happened in past
applies to improper releases of hazardous substances (not just waste)
cleanup and liability focus
contrast w RCRA
Econlockhatchee River Characteristics
characteristics
little sub-basin:
originates in developed portion of Orlando
impacted water quality from channelization, sewage plants, urban stormwater
big sub-basin:
originates in large headwater swamp
38 miles long, 25 miles wide
flows north from east
in 1990, faced intense development pressure from CF population boom
Riparian Areas
land area that borders a body of water/is influenced by that water body
options to protect riparian areas
voluntary
incentives
land acquisition
full ownership, conservation easement, but very $$
Gov Regulation
local, state, fed, or some combo
Riparian Buffer
space separating a body of water from a land mass/area
purposes:
protect both water quality and quantity
protect aesthetics
protect wildlife habitat
*width of buffer dependent upon scientific, socioeconomic, legal and political factors such as function, cost/benefit, and legal limitations
Econlockhatchee River Case
who was involved?
south john river water management district
consultants
stakeholders
friends of the econ - home builders - realtors association
property owners
consultant findings/recommendation
riparian areas provide habitat for aquatic and wetland dependent wildlife
existing local, state, and federal laws did not protect riparian areas and wildlife
econ river protection zone
protect habitat of wetland and wetland dependent species in preservation zone
prohibit most land clearing and structures in preservation zone
a 2nd conservation zone to buffer 1st zone and protect more habitat
units of gov
3 counties, 3 cities
state and regional agency authority
permits for construction/alteration require they “will not be harmful to the districts water resources”
local regional authority
broad authority to adopt local laws to promote health, safety, and welfare of community
riparian buffer regulations generally interpreted as valid purpose
Outcomes of Econlackhatchee River Case
wmd adopted regulation establishing a 550’ buffer zone
counties adopted ordinances establishing protection zone
buffer zones still in place
lawsuits challenging legality of buffer zones
did WMD exceed statutory authority?
do buffer zones cause 5th amendment regulatory takings of private property?
*highlights the ongoing battle between legal and environmental battles as it emphasizes the struggles between human activity and the preservation of critical ecosystems
Types of Air Pollution
troposphere
ozone
lungs, corrosive
nox/sox compounds
acid rain
pm
respiratory damage
lead
neuro damage
other hazardous substances like benzene
carcinogenic, mutagenic, etc
co2 buildup in atmosphere
enhanced greenhouse effect/global warming
stratosphere
03 depletion
harmful radiation
Pre-Clean Air Act (CAA)
common law
wrong against person/property
public nuisance action
duty: unreasonable interference w a right common to the public
breach of duty
causation of injury
injury
GA v TN Copper Company
f - GA common law public nuisance against TN Copper Co alleging copper smelter further destroyed forests, orchards, crops
seeking damages/injunction
i - whether court should order an injunction when evidence of causation/injury & plaintiff is a state seeking to protect citizen interests
h - yes, injunction
r - court found that the interests of GA citizens outweighed benefits of TN Copper Co
*TN Copper settled w GA
*early example of emission limitations/standards
Clean Air Act (CAA) Cont’d
toxic/hazardous materials not regulated til 1990’s
benzene, asbestos, mercury, pcb’s
carbon emissions
mobile sources - 2010’s
stationary sources - not yet
air pollution standards
ambient (background air quality)
primary NAAQS for criteria pollutants
levels set to protect human health whilst allowing an adequate margin of safety
secondary NAAQS
levels set to protect public welfare
environment, visibility, climate, property, etc
NAAQS (National Ambient Air Quality Standards)
health based
EPA must periodically review/revise criteria and standards to protect
emission standards
technology based
Whitman v American Trucking Association (1997)
f - EPA proposed stricter ozone/particulate NAAQS, which require reduced emissions from buses and trucks
i - whether EPA may consider costs when implementing NAAQS
h - EPA may not
EPA must set standards at level “to protect public health with an adequate measure of safety”
State Implementation of NAAQS
adopt SIPs (State Implementation Plans)
monitor ambient air and report to EPA
require permit for stationary sources (title v permits)
apply emissions standards
tech based standards to control pollution from stationary sources
EPA designates areas of country according to whether they meet NAAQS as:
attainment areas
non-attainment areas
areas that dont meet NAAQS
SIPs in NA areas must include
transportation control plans
offset required for new/modified sources
more stringent emission standards
other actions like burning bans
insufficient data areas
Criteria Pollutant Emission Standards
to control pollution released from stationary sources
tech based standards
existing sources (power plants)
fossil fuel burning power plants release massive amounts of pollution
existing source exemption
CAA exempts existing sources from NSPS - “grandfathered”
unless major mods resulting in
more pollution
new pollutants
if major mods, then NSPS apply
Prevention of Significant Deterioration Program (PSD)
areas cleaner then NAAQS
must preserve air quality of the area
all national parks
National Emissions Standards for Hazardous Air Pollutants Program (NESHAPS)
HAPs
no ambient standards
no systematic monitoring of ambient air for HAPs
emission standards
originally based on protecting human health
abandoned in 1990
today: MACT
maximum achievable control technology
1990 CAA amendments
tech based
specific types of industries/HAPs
MACT + Residual Risk
residual risk assessment by EPA 10 years after MACT adopted
adopt additional emission standards if risk reduction needed/protect human health
CAA Permits
emissions standards applied to stationary air pollution sources through permits
title v operating permit for major sources
NC v TVA
f - TVA coal powered power plants in TN/AL releasing air pollutants causing public nuisance that harms citizens in NC
i1 - whether TVA plants are public nuisance
i2 - whether CAA displaces public nuisance suit by NC
h - TVA plants = nuisance; CAA can not displace public nuisance suits
r - harm to NC residents > benefits from TVA plants. TVA failure to install readily available control tech is not reasonable conduct
Mass v EPA Follow Up
EPA assessed whether ghg endangered public health
EPA adopted mobile source carbon regulation (2014)
American Electric Power v Connecticut
f - 8 states + some sue alleging power plant
C emissions are public nuisance. after suit filed, Mass v EPA decided; EPA initiated rulemaking to regulate C emissions from coal power plants
i - whether CAA displaces federal common law
h - CAA displaces federal common law nuisance suits to abate C
r - CAA “speaks directly” to emissions of C
*common law suits to control C no longer allowed
WV v EPA
f - new regulation requiring existing coal fired power plants to reduce C by subsidizing more generation by gas/wind/solar sources or reduce production of electricity
i - whether CAA granted EPA authority to devise emissions caps based on “generation shifting” approach
h - no, EPA regulation is invalid
r - EPA exceeded statutory authority
*court created/applied “major questions doctrine”
*CAA does not provide EPA authority to regulate carbon from stationary sources

Land Use Planning/Regulation
local government controls how land used
town, city, county, municipality
state government adopts statutes that create some requirements for local government
federal gov not directly involved
