Title: Pollution Prevention for Municipal Operations


1
Pollution Prevention for Municipal Operations
  • Chris Kallis IEPA

2
NPDES Storm Water Programs
  • Industrial
  • Based on Standard Industrial Classifications
    and exposure to storm water
  • Construction
  • Land Disturbances gt 1 acre
  • Municipal
  • Communities in urbanized areas
  • Includes non traditional entities such as
    IDOT.

3
Municipal Operations Not Covered Under the Ms4
Permit
  • Wastewater Treatment Plants in excess of 1 MGD.
  • Landfills
  • Marinas
  • Airports
  • Steam Electric Plants

4
Storm Water Management Programs
  • Public Education and Outreach
  • Public Involvement
  • Illicit Discharge and Elimination
  • Construction Site Storm Water Control
  • Post Construction Storm Water Management
  • Pollution Prevention and Good Housekeeping for
    Municipal Operations

5
Developing an OM Program for Municipal
Operations
  • Park and Open Space Maintenance
  • Fleet and Building Maintenance
  • Operation of Storage Yards
  • Snow Dispersal
  • New Construction and Land Disturbances
  • Storm Water System Maintenance Procedures
  • Addressing Impacts from Flood Management Projects

6
Developing an OM Program for Municipal
Operations
  • The program should be designed to prevent and
    reduce the discharge of pollutants to the maximum
    extent possible.
  • Training of employees is required
  • Should address ways flood management projects
    impact water quality.

7
Landscaping and Lawn Care
  • Planting vegetation that needs minimal amount of
    care
  • Implementing landscaping techniques that minimize
    water usage
  • Watering just enough to supplement rainfall
  • Consider the possibility of using compost,
    natural or slow release fertilizers
  • Avoiding fertilizer or pesticide application
    before or during rain events
  • Consider adopting Integrated Pesticide Management
    Techniques

8
Integrated Pest Management (IPM)
  • The four steps are
  • 1. Setting Action Thresholds
  • 2. Monitoring and Identifying Pests
  • 3. Prevention
  • 4. Control

9
Vehicle and Equipment Maintenance
  • The changing of fluids and washing of vehicles
    being conducted indoors with floor drains being
    diverted to a holding tank or sanitary sewer.
  • If going to a sanitary sewer, an oil separator
    should be considered.
  • Avoiding the use of detergents as they emulsify
    oils and render oil separators ineffective.

10
Vehicle and Equipment Maintenance
  • Using drip pans when changing fluids
  • Keeping oily wastes separate from other wastes,
    especially solvents
  • Keeping coolant (antifreeze) containers covered
  • Using spigots or funnels to minimize drips or
    leaks

11
Vehicle and Equipment Maintenance
  • Keeping hydraulic equipment in good repair
  • Considering containment for fuel Islands
  • Making sure Spill Prevention and Response
    Procedures are in place and staff is adequately
    trained

Operation of Storage Facilities
  • Confining liquid and dry material storage to a
    specific indoor location.
  • Separation of potentially volatile materials.
  • Assuring drums are covered and properly stored,
    preferably indoors.
  • Assuring that drum washings are diverted to
    holding tanks or sanitary sewer.
  • Developing a disposal plan for waste materials.

15
Operation of Storage Facilities
  • Assuring that dumpsters be lidded and well
    maintained
  • Limiting the storage of scrap materials
  • Assuring that lead batteries are not in contact
    with storm water
  • Check for illicit connections to storm sewers

17
Compost Facilities
  • Making sure that the facility is located outside
    of a floodplain boundary and not placed within
    five feet of any water table
  • Insuring adequate control of runoff from the site
  • Collecting any leachate and disposing properly

18
Road Salt Storage
  • Storing road salt and sand mixtures in properly
    sized and covered structures or waterproof tarps
  • Making sure that the surface of the storage area
    is impervious and sloped to prevent runoff
  • Ordering salt early and unloading salt deliveries
    directly into storage area
  • Inspecting salt storage area to address immediate
    clean-up of spillage and exposure to runoff
  • Refer to Salt Storage Handbook from the Salt
    Institute (www.saltinstitute.org)

20
Road Salt Application
  • Minimizing salt spillage by not exceeding
    capacity of equipment during loading
  • Minimizing salt usage by periodically calibrating
    salt application equipment
  • Consider plowing before de-icing
  • Applying salt brine as a pre-treatment prior to
    impending storms
  • Using chemical application charts
  • Refer to the Chloride Reduction Study from the
    Dupage River Salt Creek Workgroup

22
Snow Removal
  • Making sure that street cleaning is a priority on
    snow removal routes
  • Placing snow piles in appropriate areas to
    minimize direct release of sediment and
    contaminants
  • Consider diverting drainage to grassy swales fro
    both primary treatment and velocity control

24
New Construction and Land Disturbance
  • All construction projects initiated by the MS4
    Permit are automatically covered. No Notice of
    Intent is required. A Storm Water Pollution
    Prevention Plan must be implemented in accordance
    with NPDES Permit conditions for each project
    that disturbs over an acre.

25
SWPPP Requirements
  • Site description that includes nature and
    sequence of construction activity and a site map
    showing activities, areas of disturbance,
    drainage, slopes and receiving waters
  • A description of stabilzation, structural and
    storm water management practices
  • Compliance with stabilization requirements and be
    at least as protective as the requirements in the
    Illinois Urban Manual 2002 edition

26
SWPPP Requirements
  • Inspections to be conducted every 7 calendar days
    or within 24 hours after a storm event of 0.5
    inches or greater
  • Incidence of Non Compliance to be sent to the
    Agency for any violation of the SWPPP
  • Insure that all contractors and sub-contractors
    identified in the SWPPP sign a certification
    statement tin accordance with NPDES Permit
    conditions.

Catch Basin and Storm Drain Cleaning
  • Identifying catch basins that require frequent
    maintenance in order to proritize
  • Identifying the need for repair of structures
    such as manholes and piping
  • Cleaning catch basins when debris has filled over
    one third of the way to the outlet
  • Coordinating catch basin cleaning with sweeping
    events checking for excessive siltation in
    ditches tributary to catch basins

30
Street Cleaning and Maintenance
  • Prioritize areas and performing maintenance
    routinely
  • Covering storm water inlets while performing
    maintenance, especially blacktopping
  • Collecting leaves in autumn
  • Sweeping salt and sand residues in the spring
  • Maintaining roadside vegetation

31
Flood Management Projects
  • Impacts to consider
  • Water Quality
  • Non Point Source Pollution
  • Maintaining aquatic habitats including the
    protection of riparian environments

32
Water Quality Protection Options
  • Ponds and Lakes in series
  • Wetland plantings
  • Aerators
  • Structural devices such as vortex units,
    oil/water separators and trash screens
  • Vegetated ditch bank programs

33
Septic System Management
  • Site Drawings should be kept of the system
    including locations of septic tank, distribution
    box and lines, seepage field or sand filter,
    chlorination tank and outlet
  • To prevent damage, avoid allowing heavy equipment
    to travel on top of the system
  • Minimize solids loading by avoiding the use of a
    garbage disposal
  • Avoid introducing materials that are not readily
    decomposed such as plastic items and trash

34
Septic System Management
  • Maintaining vegetation (preferably grass) by
    mowing regularly and removing woody vegetative
    growth
  • Inspecting systems, looking for evidence of
    problems such as sewage odors, backups of
    wastewater in lines or distribution box and
    ponding of wastewater on ground over seepage
    field
  • Pumping out septic tanks as needed
  • Coordinate with local Health Departments on
    monitoring of private systems

35
Assessing Your Program
  • Documenting Stormwater Program Activities
  • Raising Awareness
  • Changing Behavior
  • Reducing Loads From Sources
  • Improving Runoff Quality
  • Protecting Receiving Waters
