Title: NPDES Phase II Storm Water Regulations
1NPDES Phase II Storm Water Regulations
- WHAT MUNICIPAL GOVERNMENTS NEED TO KNOW
2Overview
- Why care about storm water?
- What are the NPDES Phase II regulations?
- How does Phase II affect communities?
- How much is it going to cost?
3Why care about storm water?
- Rain snow become storm water when they hit
the ground - Storm water runoff affects the health of our
waterways
4Why care about storm water?
- Natural System
- Slow absorption
- Ground water recharge
- Natural filtration
- Low runoff
- Developed System
- Decreased absorption
- Decreased recharge
- Pollutant runoff
- High runoff
- Impacts
- Erosion sedimentation
- Flooding
- Decreased aesthetics recreation opportunities
5Why care about storm water?
Pollutants fall on impervious surface
Polluted storm water enters storm drain
Storm water enters waterway
Impaired waterway
Oil in parking lot
Storm drain outfall
Typical roadside catch basin
Sedimentation and flooding during rain event
Failed silt fence
6Why care about storm water?
- Reducing vegetation / increasing impervious
surface increases storm water volume - Higher flows when it rains lower flows during
dry weather - Storm water QUANTITY and QUALITY must be managed
properly
7Why care about storm water?
- Benefits of storm water management
- Decreased flooding
- Land preservation through erosion control
- Improved wetland and riparian habitat
- Lower capital investment in infrastructure
- Reduced operations maintenance costs
8What are the NPDES Phase II Stormwater
Regulations?
- National Pollutant Discharge Elimination System,
established in 1987 under the Clean Water Act - Phase I (1990) covers industrial sites,
construction sites over 5 acres, and
municipalities over 100,000 - Phase II (2003) covers industrial sites,
construction sites over 1 acre, and ALL public
entities (municipalities and institutions)
operating separate storm sewer systems AND
contained within the U.S. Census Urbanized Area
9Phase II affects
- Cities, villages and townships in the urbanized
area - Counties
- Public institutions (schools, hospitals, prisons,
etc.) - Construction sites over 1 acre
10What are the NPDES Phase II Stormwater
Regulations?
- NPDES Phase II Goal
- To reduce the discharge of pollutants to the
maximum extent practicable to protect water
quality
11What are the NPDES Phase II Stormwater
Regulations?
Jurisdictional Public Education Illicit
Discharge Elimination Public Participation
Pollution Prevention Good Housekeeping
Construction Storm Water Runoff Control Post
Construction Storm Water Management
Watershed Public Education Illicit Discharge
Elimination Public Participation Watershed
Plan Storm Water Pollution Prevention Initiative
12How does Phase II affect communities?
- Public Education Plan (PEP) Educate the public
about reducing storm water pollution - Illicit Discharge Elimination Plan (IDEP) Map
storm sewer systems, identify and eliminate
pollution sources
13How does Phase II affect communities?
- Watershed Plan Compile water quality data across
the watershed, determine goals and actions to
achieve those goals - Public Participation Plan Involve the public in
development of watershed plan - Storm Water Pollution Prevention Initiative
Identifies water quality initiatives to be
undertaken by each community based on watershed
plan
14How does Phase II affect communities?
- Both permits require implementation of Best
Management Practices (BMPs)
- Structural BMPs
- detention ponds
- swales
- infiltration basins
- sand filters
- filter strips
- swirl concentrators
- Non-Structural BMPs
- ordinances zoning
- education outreach
- maintenance activities (drain cleaning, street
sweeping)
15How does Phase II affect communities?
- Effective storm water management requires actions
by ALL municipal departments - Actions must be coordinated and communicated
between departments and other agencies (e.g.
county)
16How does Phase II affect communities?
- Many departments have a role
- Public Works / Public Services
- Planning Zoning
- Building
- Fleet Building Maintenance
- Parks Recreation
- Finance
17How does Phase II affect communities?
- Public Works / Public Services
- Development of watershed management plan
- Structural and non-structural BMPs (e.g.
engineering standards ordinances) - Erosion control
- Public education outreach (e.g. pollution
hotline, water bill inserts)
18How does Phase II affect communities?
- Planning Zoning
- Development of watershed management plan
- Non-structural BMPs (e.g. ordinances and zoning)
- Public education outreach
19How does Phase II affect communities?
- Building
- Soil erosion sedimentation controls
- BMP implementation
20How does Phase II affect communities?
- Fleet Building Maintenance
- Good housekeeping (maintenance activities)
- Landscaping / grounds maintenance
21How does Phase II affect communities?
- Parks Recreation
- Natural features protection
- Landscaping / grounds maintenance
- Public education outreach
22How does Phase II affect communities?
- Finance
- Budgeting for Phase II
23How much is it going to cost?
- Costs vary by community based on existing
programs (e.g. ordinances, newsletter, website) - Costs for some elements (e.g. public education)
can be shared under watershed-based approach - Estimates range from 1.50 to 8 per capita
during first permit cycle
24Next steps
- Your permit application was due March 10, 2003
- Identify primary point of contact and supporting
contacts in key departments - Identify partners watershed communities, nested
jurisdictions, and other key stakeholders - Inventory existing mechanisms to meet
requirements - Begin development of draft IDEP PEP
- Begin watershed planning
25Summary
- Effective storm water management will protect and
improve the quality of our waterways over the
long term - Effective implementation of Phase II requires
cooperative efforts of a variety of departments
within each municipality - Cooperative efforts within and between regulated
entities are cost-effective
